Development of electroplating production lines at home and abroadElectroplating production lines have evolved from manual operation to mechanical and automation. Some slots are basically unused in the internal line, and the crane moves around on these unnecessary slots, which not only reduces production efficiency but also affects product quality. Selecting the automatic switch QF as the switch of the main power supply can not only achieve the short-circuit protection of the main circuit, but also play the role of isolating the three-phase AC power supply, making it more convenient to use and maintain.
In the PLC control circuit, an isolation transformer TC is designed to prevent power supply interference. The isolation transformer TC is selected. It is generally configured according to the power consumption of the PLC. Its power consumption is 40VA. Its input power supply has two types: 100~110V and 200~220V. Considering the compatibility with the power supply of external electrical appliances as much as possible, the 220V power supply port is selected for power input.
In fact, the electroplating production lines in some countries do not have such advanced predecessors. In the electroplating production line, the crane is manually operated and the operator who controls the crane follows the crane. The equipment is worse than that of some enterprises in my country. Slot positioning and arbitrary slot advancement processing Because all slots input the same signal to the PLC, in order to distinguish different slots, this software sets up a special counter. The counter increases by 1 when a slot is advanced and decreases by 1 when a slot is retreated. This is equivalent to assigning a number to each slot, and the value of the counter is the slot number.
