[0061] Working principle:

[0062] First, a PCB board with electronic components plugged in is placed on a conveyor line for conveyance. When the PCB board body moves to block the sensing line between the first transmitting module 11a and the first receiving module 11b, a first signal is sent to the control processor 8. The control processor 8 controls the first telescopic mechanism 131 to drive the L-shaped baffle 132 to move upward to the inside of the conveyor line.

[0063] Then, when the PCB body moves to contact the L-shaped baffle 132 and blocks the sensing line between the third transmitting module 13a and the third receiving module 13b, a second signal is sent to the control processor 8, causing the conveyor line to stop conveying. The control processor 8 controls the second transmitting module 12a to transmit the sensing line to the second receiving module 12b. If the sensing line is not blocked, it is determined that the welding hole on the PCB body is directly opposite the wire flow path. The control processor 8 then controls the second telescopic mechanism 23 to move the receiving box 24 downward, and controls the first telescopic mechanism 131 to move the L-shaped baffle 132 downward to not block the conveying path of the PCB body.

[0064] At this time, the receiving box 24 moves downward, causing the lower end of the wire flow channel 21 to gradually approach the welding hole of the PCB board body. In the process of the receiving box 24 moving downward, the gear 27b on the threaded rod 27a first contacts the tooth plate 27g, and the engagement between the gear 27b and the tooth plate 27g drives the gear 27b to rotate circumferentially, thereby driving the threaded rod 27a to rotate circumferentially, and then drives the movable plate 27c to move toward the receiving box 24. The push rod 26 moves along with the movable plate 27c, thereby pushing the cables in the receiving box 24 to move toward the wire flow channel 21, so that the cables located at the connection between the wire flow channel 21 and the storage slot 25 first enter the wire flow channel 21 and fall onto the closing plate 28.

[0065] In the process of cable movement, the cable to be dropped into the wire flow channel 21 will first contact the vertical block 6, and the push rod 26 will push the moving cable to move along the arc of the vertical block 6 and push the vertical block 6 to rotate circumferentially. At this time, the torsion spring 7 stores energy until a moving cable falls into the wire flow channel 21, the gear 27b and the tooth plate 27g are disengaged, the push rod 26 will stop pushing, and the vertical block 6 will reset under the energy storage of the torsion spring 7. The vertical block 6 will limit the cable still in the storage slot 25, and the cable loading operation is completed.

[0066] When the gear 27b is disengaged from the toothed plate 27g, the first roller 27k contacts the arcuate surface of the first arcuate block 27f. The downward movement of the first roller 27k pushes the first arcuate block 27f and the first vertical plate 27d to move laterally along the arcuate surface of the first arcuate block 27f, so that the toothed plate 27g does not block the downward movement path of the first roller 27k.

[0067] When the cable falls into the wire channel 21, the second roller 29c follows the receiving box 24 to move down until it contacts the arc surface of the fourth arc block 29f, and the downward movement of the second roller 29c drives the closing plate 28 to move laterally along the arc surface of the fourth arc block 29f, gradually opening the lower end opening of the wire channel 21, so that the internal cable falls into the welding hole of the PCB board body, and the wire insertion operation is completed. If the second transmitting module 12a transmits the sensor line to the second receiving module 12b and the sensor line is blocked, a blocking signal is sent to the control processor 8 to control the fourth transmitting module 42 to transmit the sensor line.

[0068] Finally, after the second roller 29c moves out of the curved surface of the fourth curved block 29f, the sensor line emitted by the fourth transmitting module 42 is received by the fourth receiving module 41, and a fourth signal is sent to the control processor 8. The control processor 8 controls the second telescopic mechanism 23 to drive the receiving box 24 to move upward, and the second transmitting module 12a stops transmitting the sensor line to the second receiving module 12b, and the fourth transmitting module 42 stops transmitting the sensor line to the fourth receiving module 41, and the conveyor line continues to convey the PCB board body;

[0069] When the second telescopic mechanism 23 drives the accommodating box 24 to move upward, the first roller 27k and the second roller 29c move upward along with the accommodating box 24. The horizontal line of the gear 27b first moves above the toothed plate 27g. At this time, the first roller 27k moves upward until it contacts the arc surface of the second arc block 27h. The upward movement of the first roller 27k drives the second arc block 27h and the first vertical plate 27d to move horizontally along the arc surface of the second arc block 27h to reset, so that the toothed plate 27g moves back to a state where it can mesh with the gear 27b.

[0070] The second roller 29c moves upward until it contacts the arc surface of the third arc block 29e, and the upward movement of the second roller 29c drives the closing plate 28 along the arc surface of the third arc block 29e to move horizontally to re-cover the lower end opening of the wire flow channel 21, thereby completing the operation of inserting a cable into the welding hole of the PCB board body.
