Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a copper plating device for a circuit board with a high aspect ratio. Background Art

[0002] Circuit boards are also called printed circuit boards. In the manufacturing process of circuit boards, copper plating not only ensures the normal operation of the circuit boards, but also greatly improves the life of the circuit boards. However, some circuit board electroplating equipment still requires manual loading and unloading, and the process is not perfect.

[0003] The Chinese patent with announcement number CN215713475U discloses a horizontal high aspect ratio circuit board microporous copper plating device, which includes a plating box, connecting blocks are arranged on both sides of the filter frame, a sliding rod is arranged on the upper end of the connecting block, and a fastening bolt is arranged on one side of the sliding rod. Before the copper plating process, the operator pulls the sliding rod upward to drive the connecting block and the filter frame to move upward. When the upper surface of the connecting block moves to contact the inner wall of the side groove, the fastening bolt is rotated at this time to fix the sliding rod, that is, the filter frame is fixed. During the rising process of the filter frame, the suspended matter in the electroplating solution will stay above the filter frame, and the electroplating solution before filtration is below the filter frame and can be discharged through the liquid outlet pipe. At this time, the scraper is on the same horizontal line with the side groove and the filter frame. The operator uses the switch to make the cylinder push the scraper to move, so that the suspended matter on the surface of the filter frame can be removed. The operation is relatively simple and practical.

The pulley 702 drives the water absorption roller 703 to operate. When the water absorption roller 703 clamps the circuit board, the spring telescopic rod two 705 will adaptively extend and retract to ensure that the circuit board is not crushed. The water-absorbing roller 703 drives the circuit board to the storage table 901 via the moving table 900. At this time, the grabbing component 800 is running, the electric telescopic rod three 812 descends, and the electric telescopic rod four 814 extends to drive the fixed plate two 813. After it descends to a suitable height, the electric telescopic rod four 814 contracts and drives the fixed plate two 813 to limit the circuit board. Then the electric telescopic rod three 812 rises, and the motor three 802 drives the gear 803 to move and bring the circuit board to the top of the electroplating tank. Then the electric telescopic rod three 812 descends to put the circuit board into the electroplating tank for electroplating. After the electroplating is completed, the electric telescopic rod three 812 rises, and the motor three 802 drives the gear 803 to move in the tooth groove 8 04 moves to drive the mechanical claw 810 to bring the circuit board to the top of the second water washing tank, the electric telescopic rod three 812 descends, and after it reaches a suitable height, the electric telescopic rod four 814 extends to release the circuit board, and the circuit board falls steadily on the second water washing filter 603, and then the grabbing component 800 is reset. The second water washing process is consistent with the first water washing process. After the second water washing is completed, the moving component two 510 is operated to send the circuit board through the partition curtain 611 to the conveyor belt two 606 inside the air drying box 102, the transmission roller 607 and the fan 609 operate synchronously, the transmission roller 607 drives the conveyor belt two 606 to rotate, and the conveyor belt two 606 drives the circuit board to move backward, during which the fan 609 performs an air-drying operation on the circuit board.
