Chen Demu, Chairman of Hangzhou Jiepai Transmission Technology Co., Ltd.

1. Industry Development

Gears are the most common way of mechanical transmission. The reducer is a transmission component composed of multiple gears. It mainly uses the meshing of the gears to change the motor speed, torque and load capacity, and can also be used to achieve precise control. Among them, the gear reducer is the core component of the energy transmission and power transmission device in the industrial system, and is known as the "chip" of the machinery industry.

Starting from the production of reducer accessories, JIE has independently developed and launched various industrial reducer products such as worm reducer and gear reducer, and has rich experience in research, development and manufacturing of transmission equipment. Chen Demu said that the reducer can be regarded as a subdivision of gears. According to different usage occasions, gear products can be roughly divided into vehicle gears and industrial gears. Among them, industrial gear devices are mostly customized products, which need to be specially designed and matched with the requirements of the host machine, and only a small part are serialized standard products. If further subdivided, industrial gears can be divided into medium and large and small and medium, and small and medium can be divided into two types: general-purpose and special-purpose. In logistics equipment, the application of general-purpose reducers is the main one.

The gear industry is a technology-intensive industry. As a key transmission component, it has the characteristics of precision, high efficiency, safety, and reliability. It puts forward high requirements for the accuracy and hardness of gear products. In recent years, with the development of new materials, numerical control automation and other technologies, the production quality and production efficiency of gears have been rapidly improved. The manufacturing industry of gears and transmission parts in my country has made significant progress, and the transformation from a big gear manufacturing country to a manufacturing power has been accelerated. However, due to the more stringent requirements for high-end products on technology, technology, and materials, most domestic companies still have shortcomings in R&D and manufacturing. There is still a large gap.

Taking the widely used reducer as an example, Chen Demu said that my country's reducer industry is in a polarized situation, with excess capacity in the low-end market and reliance on imports in the high-end market. At present, there are a large number of reducer manufacturers in the country, but the scales are large and small, and their development levels are different. In the high-end market, only a small number of local companies with a certain scale and technological advantages have entered the mid-to-high-end field as effective alternatives.

According to his observation and judgment, the industry is approaching the time window for reshuffle and reorganization. Local enterprises need to improve their technological level and accumulate continuous technology research and development to adapt to the fierce market competition environment; that is, enterprises with technological advantages and rich production experience have It may become an integrator and snatch the market share of high-end products from international leading enterprises, while enterprises with serious homogeneity and relying on low-price competition may be integrated or even withdraw from the market.

2. Intelligent evolution

In order to adapt to industry development and market changes, JIE has been established for more than 30 years. It has developed from a pure transmission equipment manufacturer to a provider of intelligent transmission solutions, and strives to become an innovator, changer and leader in the industry. Chen Demu said that the reason why Jiepai wants to upgrade from professional efforts to intelligence is mainly based on the judgment of the general trend, "We must look at the present from the past, not the present from the past."

JIE intelligent transmission solution

Looking at the development trend of the global gear industry, Chen Demu believes that it is in the stage of gradual evolution from version 1.0 to version 4.0. At present, most domestic enterprises are still in the version 1.0 stage, mainly focusing on the production of simple transmission products such as worm reducers, gear reducers, and planetary reducers; a few enterprises are exploring version 2.0, and strive to expand and other transmission equipment and systems; international well-known enterprises are in the leading position in version 3.0, and have advantages in transmission systems, drive systems, control systems, etc. Intelligent digital technology, and strive to become a "smart transmission solution provider".

In Chen Demu's business philosophy, enterprises should not be "big and comprehensive" or "small and comprehensive", but should master the core technology and specialize in the technical industry. To this end, JIE adheres to the development plan of "specialization, intelligence, and globalization", invests 500 million yuan to build a smart factory with Industry 4.0 standards, and forms an innovative model of "JIE Intelligent Transmission Research Institute Science and Technology Innovation Center Future Factory" , to promote the upgrading of enterprises from production platforms to innovation platforms.

Today's JIE adopts the world's leading complete set of European and American imported equipment and technology, and provides various high-quality intelligent gear reduction motors, intelligent industrial gearboxes, intelligent planetary gearboxes, high-efficiency worm reducers, and high-efficiency motors to domestic and foreign customers in strict accordance with industry standards. , Servo motors and servo drives, frequency conversion integrated geared motors and frequency converters, intelligent monitoring systems and intelligent transmission solutions. In addition, it is committed to the project planning of the whole process ecosystem, multi-system data middle platform, and integrated industrial platform and the implementation of the optimal solution for lean production in the whole value chain. By applying technologies such as big data, cloud computing, Internet of Things, and artificial intelligence, it can realize Intelligent manufacturing and intelligent monitoring operation and maintenance of transmission products such as reducers.

3. Help logistics

Through continuous R&D and innovation, JIE has launched a series of core software and hardware products with independent intellectual property rights, such as JRT intelligent gear reduction motor, JRH intelligent industrial gearbox, JRP intelligent planetary gearbox, JRW high-efficiency worm reducer, JD high-efficiency motor , JC intelligent transmission scheme, etc. Among them, JRT intelligent geared motors have the advantages of beautiful appearance, low noise, no oil leakage, fast delivery, intelligence, and no faults, including JRTR geared motors, JRTF parallel shaft-geared motors, JRTK bevel geared-geared motors , JRTS worm pair - gear reduction motor and other full range of products.

JRT intelligent geared motors follow the concept of modularization and optimization design. The whole series of products include geared motors and frequency conversion integrated geared motors. They support AD type solid shaft input, AM type IEC motor input, AQS type servo motor input, and AN type NEMA motor input. Various input interface types, such as solid shaft output, splined hollow shaft output, and shrink disc output, etc., support various installation types such as foot mounting, flange mounting, and torque arm mounting, and support multi-stage Modularization and integration of reducers and reducers of different models and specifications, and personalized design and manufacture according to customer needs.

In addition to making good products, JIE is also exploring the sinking service market and entering more subdivided fields, and the logistics industry is one of them. "Behind smart logistics is smart logistics equipment, and behind smart logistics equipment is smart transmission solutions." In Chen Demu's view, from flat warehouses to three-dimensional warehouses, from relying on labor to relying on machines, the logistics market has huge potential. But he also realized that logistics companies serve many industries and involve many application scenarios, such as e-commerce logistics, express logistics, factory logistics, airport logistics, etc. Each field has its own characteristics. The logistics robots and conveyor lines used Logistics equipment such as logistics equipment, stackers, etc. have different requirements for transmission devices. High reliability, high safety, fatigue resistance, long life, and low failure rate are common requirements, which leads to the fact that high-end parts of logistics equipment are still the main components. Rely on imports.

Chen Demu said that the demand for transmission of logistics equipment is not only a single reducer, but a combination of a series of software and hardware systems such as reducer, motor, and frequency converter. "These technologies belong to different fields and require cross-border and integration of technologies, which is a huge challenge for companies that simply manufacture reducers." He believes that many domestic reducer companies cannot meet the needs of the entire logistics equipment. The biggest gap with imported equipment lies. JIE, however, can better facilitate the upgrading of intelligent logistics equipment through intelligent transmission solutions such as "reducer, motor, frequency converter, sensor, Internet of Things" and intelligent digital technology of "execution layer, collection layer, drive layer, control layer, application layer".

4. Landing application

With superior and stable performance and the support of intelligent systems, currently JIE related transmission devices and systems are widely used in logistics equipment such as stackers, conveyor lines, elevators, etc., and have cooperated with China Post, JD Logistics, SF Express, Beiqi Logistics and equipment companies such as China Academy of Sciences and Hangcha have established long-term and deep cooperative relations.

In JIE's future factory, its intelligent transmission solution has been applied in all aspects. According to reports, Jie brand's intelligent warehousing and logistics system covers No. 1 factory, No. 2 factory, No. 3 factory, raw material warehouse, semi-finished product warehouse, finished product warehouse, box smart factory, gear smart factory, motor smart factory, assembly smart factory, etc. Logistics, transportation, storage and distribution of 50,000 kinds of materials in JIE Intelligent Transmission Industrial Park; the main equipment used includes 50kg stacker, 1.2T stacker, 2.4T stacker, 20,000 bins, and 20,000 pallets Position and AGV, RGV, elevators, etc.; the main intelligent products involved are frequency conversion integrated geared motors, distributed and cabinet-mounted inverters, controllers, servo motors, servo drives, etc.

JIE intelligent transmission solution helps the logistics equipment industry to upgrade

Chen Demu said that according to the characteristics of the logistics industry and the characteristics of logistics equipment, corresponding design and adjustment should be carried out in product research and development. For example, most of the stackers are high in height and fast in operation speed, and are prone to problems such as swinging, shifting or even overturning of the goods during the emergency stop process. In order to ensure safe and stable operation, JIE has built-in low-speed The backlash gear and algorithm have the function of anti-momentary swing; the expanded design of the motor can make the acceleration higher and ensure the transmission efficiency, and its geared motors adopt double-coil brakes for fast braking to ensure the stability of the stacker. precise positioning.

Due to the closed operation of the stacker, there are great limitations in the later maintenance. JCI intelligent monitoring system of Jie brand can resolve the problem. The system has the advantages of saving labor costs, ensuring the operation of production lines, eliminating potential safety hazards, avoiding unplanned shutdowns, and remote real-time monitoring of operation and maintenance. It can provide customers with information including temperature, vibration, voltage, current, air pressure, humidity, and geographical location. Information; following the concept of modularization and optimization design, the system integrates technologies such as Internet of Things, cloud computing, big data analysis and artificial intelligence, and can provide customers with remote status monitoring and intelligent operation and maintenance services of reducers and geared motors, status monitoring Data cloud diagnosis and analysis, remote push of bearings, gears and other key parts status assessment reports and maintenance plans and other services can also be customized according to customer needs.

In fact, intelligent monitoring is an important part of JIE Intelligent Transmission Solution. Through the JIE Intelligent Platform (JIEIoT), life expectancy and health management can be better predicted, and intelligent monitoring can be used to facilitate intelligent operation and maintenance; the platform has energy management, health Management, audio-visual management, operation and maintenance management, parts management and other functions can solve the pain points of factory operation and maintenance such as operation and maintenance costs, production stop loss, safety accidents, etc., and realize the perfect linkage between online and offline, domestic and foreign. According to JIE’s internal statistics, through intelligent monitoring services, user investment costs can be reduced by 30%, manual operation and maintenance costs can be reduced by 80%, and economic losses caused by unplanned downtime can be reduced by 80%.

5. Future development

As the core components, the quality and technology of transmission products such as reducers directly affect the performance and market performance of logistics equipment. At the same time, the needs of users change, and the requirements for diversification, personalization, and intelligence are gradually increasing. In response to changes in market demand, local transmission companies are facing new challenges. JIE will use the future factory as the basis to strengthen production and manufacturing, innovative R&D capabilities and service levels.

1. Based on the "future factory"

The future factory built by JIE through years of digital transformation includes operation command center, intelligent central warehouse, box intelligent factory, gear intelligent factory, motor intelligent factory, assembly intelligent factory, intelligent inspection test, intelligent park management, etc. part. Under the overall planning of the whole value chain lean production "future factory", not only the production capacity has been greatly improved, but also the "full system, multi-process and integrated" management can be realized by using technologies such as big data, cloud computing and Internet of Things. Through process and layout optimization, JIE realizes the transformation from "discrete manufacturing" to "process manufacturing", and enables its intelligent transmission scheme to be applied and innovated in the real scene of the future factory.

In the process of JIE upgrading from specialization to intelligence, and from a manufacturing enterprise to a manufacturing service enterprise, the future factory plays an important supporting role. Chen Demu said that based on the future factory, JIE will position itself as "specialized, specialized and new", and strive to realize independent controllability for every product and every technology, and break through the "stuck neck" technical problem.

2. Ensure high quality delivery

In order to take the initiative in market competition and compete with foreign brands, JIE pays special attention to QCD (Quality, Cost, and Delivery). According to Chen Demu, in order to make a good product, Jiepai will do five confirmations: product demand confirmation, product proposal confirmation, product appraisal confirmation, product mass production confirmation, product delivery confirmation, and finally ensure that high-quality products are delivered to customers.

In his view, the quality assurance of products is the bottom line. During the whole process of manufacturing, JIE will follow every technical standard, process standard, quality standard and acceptance standard, through online processing inspection, online assembly test and real-time inspection Test to ensure that each part is free from defects, each product is delivered perfectly, and the warranty period will be extended by 6 months compared with imported products. At the same time, Jiepai puts more emphasis on comprehensive cost performance, and can quickly carry out product design according to the individual requirements of customers, form a production plan, and meet the specific requirements of customers at a reasonable cost and within a shorter delivery period.

4. Join hands to build a new ecology

The specialized division of labor in the industrial chain will bring more opportunities for industry development. Chen Demu said frankly that the reducer is the first product of Jie brand, and it must be done well. For the bolts, gaskets, sealants and other accessories in the reducer, professional suppliers will be found to build a new ecology with the upstream and downstream. It is reported that JIE, from supply chain management, innovation chain integration, industrial chain development, value chain coordination to ecological chain construction, has passed the 3 million project (training 100 excellent employees, integrating 100 excellent suppliers, serving 100 excellent customers) ) to build an industrial alliance and achieve win-win cooperation.

Chen Demu believes that no matter how the market changes, only companies with strong research and development capabilities, stable product quality, high service levels, and strong sustainable operation capabilities can take the lead in the market. In the future, JIE will be based in China, export to Europe and the United States, and serve the world.
