[0025] Working principle:

[0026] First, place the base plate 1 on a flat table or ground. Then, press the clamping plate 10 inward. Next, place the PCB circuit board to be electroplated into the groove 13 between the two symmetrical clamping plates 10. Then, release the clamping plates 10. The clamping plates 10 will automatically reset under the action of the telescopic rod 8 and the spring 9, thus clamping and fixing the PCB circuit board. After all the PCB circuit boards are installed, tighten the bolts 12 one by one. The bolts 12 will push the pressing block 14 to move, thereby fixing the PCB circuit board into the groove 13 and improving the stability of the PCB circuit board. After all the PCB circuit boards are installed, turn on the servo motor 5. The servo motor 5 will drive the circular... The disc 7 rotates slowly, allowing the PCB circuit boards between the two clamping plates 10 to sequentially enter the electroplating solution 4 for electroplating.

After electroplating is completed, the piston 11 is removed to discharge the electroplating solution 4. The disc 7 continues to rotate slowly, allowing the electroplating solution 4 adhering to the PCB circuit boards to detach quickly. Finally, the servo motor 5 is turned off and the PCB circuit boards are removed.
