[0034] A new type of PCB processing tool and its application method:

[0035] Step 1: The spring 24 drives the shift block 22 to move backward, so that the pin 23 is inserted into the lock hole of the frame 1, and then the drawer 2 is fixed in the placement slot of the frame 1. The worker holds the grip 21 with his right hand and uses his right thumb to shift the shift block 22 forward, so that the shift block 22 drives the pin 23 to separate from the lock hole. At this time, the grip 21 can be pulled to the left to slide the drawer 2 out of the placement slot to the left, thereby facilitating the inspection and maintenance of the tool body 25 located in the placement hole of the drawer 2.

[0036] Step 2: The electrical equipment in the entire device is controlled by the controller 12 to work. When a drill bit needs to be installed on a group of drilling machines 11, the clamping plate 493 and the tool body 25 located in the placement hole of the drawer 2 are visually monitored by the visual probe 31. The visual probe 31 determines the information of each tool body 25 based on the mark 26 on the top of the tool body 25. When a tool body 25 needs to be taken, the first motor 4 drives the first screw 41 to rotate, and then drives the first internal thread slider 42 to slide left and right. The first internal thread slider 42 drives the electric telescopic rod 44 to slide left and right through the slide plate 43, and then the electric telescopic rod 44 can drive the clamping plate 493 to move backward. When the clamping plate 493 moves to the top of the tool body 25, the second electric The machine 48 drives the second screw rod 46 to rotate, and drives the second internally threaded slider 47 to move downward through the second screw rod 46, and then drives the clamping plate 493 to move downward through the second internally threaded slider 47. When the two groups of clamping plates 493 move downward to the left and right sides of the tool body 25, the bidirectional screw rod 491 is driven to rotate by the third motor 494, and the two groups of third internally threaded sliders 492 are driven to move inward through the bidirectional screw rod 491, thereby driving the two groups of clamping plates 493 to move inward to clamp the tool body 25. When the clamping plates 493 are misaligned, the controller 12 controls the device to stop working, and the sound and light alarm 3 sounds an alarm, and then the second motor 48, the electric telescopic rod 44 and the first motor 4 perform a reset operation, thereby driving the clamping plates 493 to move to the initial position.

[0037] Step three: Since the positions of the multiple groups of drilling machines 11 inside the frame 1 are fixed, the controller 12 controls the first motor 4, the electric telescopic rod 44 and the second motor 48 to cooperate with each other according to the position of the drilling machine 11 where the drill bit needs to be installed, and inserts the tool body 25 clamped and fixed by the clamping plate 493 into the tool hole at the bottom of the drilling machine 11.
