In a complex manufacturing line, each component looks like it has long eyes. Through its own RFID system, it can automatically find the required parts and components, and the qualified rate of one-time assembly of the production line is about 85%. Yesterday, the reporter learned from the Chongqing Municipal Science and Technology Commission that the “863” project “Development and Application of Radio Frequency Identification Technology for Discrete Manufacturing Process Management” has passed the inspection and acceptance. The first discrete manufacturing RFID production line in China is in Longxin Industrial Co., Ltd. Completed investment.

Into the company's production workshop, a motorcycle frame, parts, engines, etc. in the pipeline, step by step, sitting on the side of the assembly of the workers, like a robot, from a fixed place, take a fixed Parts, tight screws, complete assembly, almost no mistakes.

“This kind of orderly and accurate assembly can be very rare in the previous manufacturing line.” Liu Youxing, Deputy Director of the Department of System Management of Longxin Industry Co., Ltd. introduced, in the past, the production plan of the production line for one day, as well as The procedures for ingredients, assembly, testing, etc. needed by each station are all manually issued. The head of the shift on duty is then notified verbally by the team leader. It will waste a lot of time and manpower and the efficiency will be low.

"Every day there are about 6 or 7 mistakes in material distribution or assembly. The pass rate for one-off assembly is only 55%-70%," he said.

Today, the production line equipped with an RFID system is completely different. At the scene, the reporter saw that each motorcycle frame on the production line was equipped with an RFID chip, and the chip collected all kinds of information, including its type, quality, and even suppliers.

Then, through the radio frequency identification of the frame and the components, the components to be installed will be accurately delivered to the front by the production line. After the completion of the work, the information will be automatically written into the chip; and what it needs next. The system will also automatically prepare for it and implement "one to one correspondence" in each process.

“It is like installing a 'eye' for a fully automatic assembly line, and the components will identify each other and complete the assembly accurately. The management personnel can complete the material distribution, testing, packaging, etc. as long as they are sitting in the office.” As the R&D team takes the lead Liu Weining, professor at Chongqing University, said that due to the “one to one correspondence” between parts, the system can accurately respond to various temporary or random changes in production plans, so that the one-time qualification rate of manufacturing lines can be increased to 80%—85. %.

At present, Chongqing has been listed as a pilot unit by the Ministry of Science and Technology. This "Chongqing-made" radio frequency identification production line model for discrete manufacturing is about to be promoted nationwide.
