[0033] Embodiment

[0034] When the device is used, it is used in cooperation with a thickness gauge, and is applied to the adjustment of the die screw 13, and the process is as follows:

[0035] The thickness information of the die surface scanned by the thickness gauge is fed back to the PLC, the PLC automatically runs the linear module 2 through AI algorithm and PID control, the vertical adjustment mechanism is run to the die screw 13, at this time the vision camera 5 works to take the position and angle of the screw that needs to be adjusted, the light source 6 can provide ambient light during this time, then the vertical adjustment mechanism is lowered to the screw adjustment position, the locking motor 7 (the locking motor 7 is a rotary drive motor) moves, the screwdriver bit 8 adjusts the position of the die screw 13, after the end, the vertical adjustment mechanism rises, the linear module 2 returns to the initial position, the thickness gauge continues to measure and feed back the thickness information, and the process is repeated to realize the automatic control of the thickness.

[0036] When the vision camera 5 works, the position and angle of the screw that needs to be adjusted are judged through AI recognition, and the process is as follows:

[0037] Firstly, the vision camera 5 adopts a vision sensor with a model of MV-CA050, a resolution of 300,000 pixels, and a frame rate of 60 frames per second.
