"Having cut employment by half, production efficiency has increased by 108.28%, product non-performing rate has dropped by 27.56%, labor cost has been saved by 50 million yuan." Behind this series of figures, it is one of the results of Guiyang Hisense's implementation of a smart manufacturing strategy.
In the LCD TV production room of the Hisense Industrial Park in Guiyang Economic Development Zone, a yellow intelligent robot about 2 meters high is transmitting a large 65-inch screen. This yellow robot is a PCBI precision and heavy-duty assembly robot introduced by Hisense at the end of 2016. It is mainly used to produce products of 43 inches or more.
“The plane articulated robot, the auto-reversing robot, the PCBI precision and the heavy-duty assembly robot are all on the battlefield, and smart devices are readily available.†Wen Honggang, secretary of the party committee of Guiyang Hisense Electronics Co., Ltd., said that in the TV assembly line, each TV needs 600 to 800 components, all through the intelligent program to guide AGV to complete the transport, daily intelligent robots will be in accordance with the production model and a number of different configurations, through data identification, automatically transfer raw material information to the system platform, and then The parts need to be scattered into each ingredient box and automatically distributed, allowing workers to save time and effort.
Prior to this, Guiyang Hisense's production workshop mainly informed delivery personnel via walkie-talkies or telephones, and its timeliness and accuracy were relatively poor. Nowadays, with this intelligent system, not only has the accuracy of material distribution been improved, but a production line has also saved the cost of labor for at least seven distribution staff.
Before June 2015, the production cycle of the module machine production line was 24 seconds. Through the manufacturing upgrade, the production cycle of the GM1 line was increased to 14 seconds in the second half of 2015, and the production cycle of the GM2 line was raised to 17 seconds. And it is superior in quality and speed compared to previous manual operations. Guilin Li, head of the comprehensive management department of Guiyang Hisense, said that when the number of Hainan’s largest employees reached 1,000 people, it has been gradually reduced to 500 people through the transformation of intelligent production lines for many years. Employees have decreased, but production capacity has risen. Guiyang Hisense's annual production has increased from nearly 700,000 units in 2011 to 1.9 million units in 2017, an average annual increase of more than 10%.
"At present, the company has 12 intelligent systems in use, covering raw material warehouse management, logistics management, electronic operations, etc.; robots, automation equipment, etc., have been widely used in production, inspection, packaging and other aspects of the company's production. Accuracy and efficiency have increased dramatically.
"With the diversification of market demands, we have upgraded and upgraded our products from appearance, color, and performance to produce a variety of products that meet market demands." Wen Honggang said that Guiyang Hisense's laser TV products will not only break the past The monopoly of devices by foreign companies has also completely changed the traditional mode of TV production. In July of last year, Guiyang Hisense became the only TV manufacturer in the list of “Smart Manufacturing Pilot Demonstration Projects 2016†issued by the Ministry of Industry and Information Technology. In the next step, Guiyang Hisense will continue to develop in the area of ​​“big data + industry†and will apply for national-level “smart manufacturing special projects†and “green manufacturing special projectsâ€.
Since entering Guiyang in 1997, Guiyang Hisong has achieved a leapfrog development. After 20 years of efforts, small businesses with an annual output of 50,000 sets of color TVs now have 3 modern factories, 3 machine lines and 3 module production lines. , 3 substrate production lines, 3 SMT chip lines, has formed a 32-65-inch large-screen LCD flat panel full range of product production capacity, the products are exported to more than 10 provinces and regions in the Midwest. In 2016, the output value of Guiyang Hisense reached 6.005 billion yuan. This year, as of the end of October, the output value reached 5.45 billion yuan.
The speed is not reduced, and the quantity is even better. Guiyang Hisense is making its way into the smart manufacturing of the entire industry chain.
What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.
A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.
The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.
The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.
Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.
At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
