This project is mainly to develop a precision and efficient automatic stamping production line to achieve automatic stamping loading and unloading, and combined with the use of PLC and sensors, real-time perception and collection of the production line each station production of products and operating status, component status adjustment and optimization, to achieve self-fault diagnosis, can identify and isolate faults, users can online monitoring, fault prediction and diagnosis. Thus from the previous pure manual loading and unloading to automatic loading and unloading, manual operation reduced by 75%, effectively reduce labor costs and labor, production efficiency reached 7~8s/ piece, product output product pass rate increased to 99.9973%. The project scheme can be copied quickly, has demonstration in the punching line, and has broad market prospects.
