PLC Network Control System In The Car Axle Production Line Of Welding

Along with the automated industry's development, our country industrial automation advancement had already made the progress which attracts worldwide attention. And the manufacturing industry development is especially rapid, already became promotes our country economy rapidly expand the key forces and the supporting profession. The auto part manufacture such as automobile vehicle bridge welding installs the production line also in gradually to develop to the entire automated direction, domestic auto part enterprise production line's automaticity also in corresponding enhancement. But, still had the productivity to be low, waste serious and so on phenomena.The present paper mainly aims at the automobile vehicle bridge welding machine production line's control system to carry on the design, uses MITSUBISHI Corporation's Q series PLC to take the control core, using the ethernet, the MELSECNET/H net and CC-Link the field bus takes the directed net, the entire strip production line may come the flexibility change own practical capacity along with the consumer market demand. This article will be precisely under this situation, the control system will apply in the Jiangsu great wild goose flies in circles the automobile vehicle bridge welding to receive produces, will cause it under the secure premise the enhancement production efficiency as far as possible.The present paper has first carried on the PLC network control system's integrated design. The field apparatus carries on the connection through the CC-Link field bus and the MELSECNET/H net and Q12H CPU to form the directed net and to carry on the data to be interactive, the labor controls on PC machine to install the MCGS configuration software carries on the control signal transmission and the data acquisition through the ethernet module and Q12H CPU. This article discussed the production line PLC three network designs with emphasis. The first floor device control part basis performance-to-price ratio as well as the customer demand, use the Mitsubishi FX series or Q series PLC separately carry on the control, and has the vinylon touchscreen by to facilitate field personnels' operation; The first floor device control part also through the CC-Link field bus and the MELSECNET/H net connection is a whole; The workshop control station may have the MCGS labor through the installment to control in the PC machine gain production line production process the real-time data information.Present paper's PLC network control system's not only reduced the production cost in automobile vehicle bridge welding production line application design, raised the vehicle bridge production system's productivity, moreover the entire vehicle bridge welding control system improvement process's research many enterprise production lines improved the work for the profession to provide the successful case reference, heightened the national enterprise automobile vehicle height quality production confidence.
