It is mainly composed of power supply module, CPU module, digital input and output module, analog input and output module, communication module, base plate or guide rail, expansion cable, special module, etc. On the one hand, it is the signal loop input to the PLC, and on the other hand, it is the circuit output by the PLC to the control components. The PLC input and output circuits and components constitute a complete control system. The PLC circuit board usually needs to be welded during the production process;

[0003] The existing technology usually uses an automatic welding device to perform circuit board welding operations. However, the existing automatic welding device has a simple structure.
