[0002] When performing immersion gold plating on PCBs, it is necessary to manually stack batches of circuit boards together, separating them with plastic spacers. Multiple copper wires are then threaded through holes on the edges of the boards to connect them into groups, which are then hung on the immersion gold plating production line for processing. According to industry insiders, this work is currently done manually in production factories. This work is tedious, labor-intensive, and inefficient.

[0053] In this specific embodiment, the front end of the conveying component 3 may optionally be provided with a flip plate 31, which is used to flip the stacked PCB board 4 by 90 degrees and then transport it to the conveying component 3.

[0054] Working principle:

[0055] At the start of the work, the PCB board is subjected to immersion gold treatment. At this time, the edges of the PCB board 4 are covered with adhesive tape to protect the sides of the board and prevent the chemical from seeping into the board. Therefore, the through holes are covered. Before inserting the board, the adhesive tape must be pierced with a needle. Multiple PCB boards 4 are stacked on the feeding mechanism 12. When the robot arm 13 of this station picks up the board from the feeding mechanism 12 with its four-axis robot, it is positioned by CCD vision correction and placed in the positioning position. The board holes are aligned with the four preset positioning needles 14 and then pressed down to pierce the adhesive tape, thus completing the board positioning.

[0056] Next, the PCB board 4 is attracted to the pallet chain assembly 24 using suction cup 213. At this time, the shearing assembly 26 is aligned with the PCB board 4 after the position adjustment assembly 27 and itself move in the shearing module 261. The pallet chain 246 moves downward under the drive of the pallet chain motor 244, approaching the wire feeding mechanism 265. The wire feeding mechanism 265 pulls out the copper wire 5 wound on the copper wire reel 263 through the straightener 264 and passes it upward through the four small holes pierced by the positioning needle 14 on the PCB board 4. The copper wire traction clamp 2662 located in the stroke module 262 clamps the copper wire 5. When the copper wire 5 in the four holes is clamped by the corresponding four copper wire traction clamps 2662, the vibrating plate 221 vibrates, injecting the isolation column 2676 into the lower column tube 2672 through the hose 222. With the cooperation of the push column cylinder 2673 and the column separating block 2674, it is inserted into the copper wire 5. Then, continue to repeat the above actions to form an interval between PCB board 4, isolation column 2676 and PCB board 4, and place PCB board 4 with isolation column 2676 in place on the transmission belt of lifting output component 25 through tray chain 246.

[0057] The conveyor belt 255 is designed to be adjustable in size, which can be adjusted according to the size of the PCB to be processed.

[0058] After the PCBA boards are stacked, the bending cylinder 2682 controls the bending head 2684 to extend, inserting one end of the copper wire 5 into the bending head 2684. Under the control of the bending cylinder 2683, the bending head 2684 rotates, cooperating with the bending arc plate 2685 to bend the copper wire 5. After the upper part is bent, the wire cutting mechanism 266 descends to the bottom under the drive of the stroke cylinder, and the copper wire 5 located at the bottom of the PCB board 4 is cut by the cutting cylinder 2661. After cutting, the copper wire 5 is bent again by the bending component 268, thus completing the board threading operation of the complete PCB board 4. The conveyor motor 253 of the lifting output component 25 starts, and the stacked PCBA boards are sent to the conveyor component 3 via the conveyor belt 255. After the finished board is output, it is rotated 90 degrees by the flipping plate 31, so that the side of the board group contacts the conveyor belt. This prevents the board surface from deforming under force and also saves the length of the temporary storage and receiving conveyor belt. When the conveyor belt is full, a sensor detects and triggers an alarm to alert the operator to remove the tray.
