It should be noted that when the Z-axis servo linear module 8 works to drive the mounting frame 9 to descend, the screwdriver head 19 moves to the screw. At this time, the guide column 9 cooperates with the spring 15 to enable the lifting slide 21 to drive the servo motor mounting plate 14 to move on the mounting frame 9, thereby achieving a buffering effect and making the screwdriver head 19 better fit with the screw thread, thereby achieving the detection effect of tightening the screw and then loosening it.

[0026] Specifically, the socket placement plate 11 has a plurality of placement slots 21 corresponding to the servo motor 17, and a plurality of auxiliary blocks 23 are arranged at one end of the placement slot 21 away from the product positioning assembly 102.

It should be noted that when one of the servo motors 17 drives the screwdriver head 19 to work and detects a defective product, the corresponding product defect indicator light 3 lights up, which will remind the operator to remove the defective product in time.

[0031] The working principle of this specific implementation is as follows: first, manually place the socket products in 21 in turn, then use the auxiliary cylinder 28 to drive the transmission rod 27 to move, so that the socket placement plate 11 moves to the required working position, adjust the socket to be detected, and then use the product positioning cylinder 24 to drive the auxiliary positioning clamping plate 22 to move above the socket placement plate 11, so that the auxiliary positioning clamping plate 22 is close to one end surface of the socket and cooperates with the placement groove 21 and the auxiliary stopper 23 to position the socket, and then the three-axis linkage adjustment screwdriver head 19 of the Y-axis servo linear module, the X-axis servo linear module, and the Z-axis servo linear module is used. When it reaches the required working position above the socket, the Z-axis servo linear module 8 drives the mounting frame 9 to descend, and the screwdriver head 19 moves to the screw. At this time, the guide column 9 cooperates with the spring 15 to make the lifting slide 21 drive the servo motor mounting plate 14 to move on the mounting frame 9 to achieve a buffering effect. At the same time, the screwdriver head 19 can better fit the screw thread, thereby realizing the detection effect of tightening and then loosening the screw. If defective products appear during the detection process, the corresponding product defective indicator light 3 will light up to remind the operator. After the detection is completed, the screwdriver head 19 is reset away from the socket, and the auxiliary positioning clamp 22 is away from the socket, and the detected product can be removed.

[0032] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
