[0034] Working principle: When in use, through software control, the red light generator 30 fixed on the beam 22 emits red light through the galvanometer 301 to locate the PSD sensor module for scanning. After receiving the red light, the PSD sensor module will transmit the signal to the computer. The computer will calculate the corresponding coordinate value through the software, and then read the PSD sensor module value through the software, fine-tune the galvanometer motor position in the galvanometer 301, so that the PSD sensor module reading is within the error range of the predetermined standard value, and complete the precise size debugging. Then, the galvanometer 301 is controlled by software to hit the left, right, up and down sensors. By adjusting the galvanometer 301PID, the PSD sensor module reading is made to be within the error range of the preset standard value, and accurate dimensional debugging is completed. After the calibrated 2D galvanometer system is tested on the treadmill for 10 minutes, 20 minutes, 30 minutes, 1 hour, and 2 hours, the PSD software will automatically collect the signal values ​​during this period, convert them into coordinate differences, and then obtain the temperature drift value of the equipment through mathematical and statistical analysis by the software, and automatically generate a test report, including center error, dimensional deviation, and temperature drift, which intuitively shows the debugging results of this 2D galvanometer.

Since the workpiece usually has a multi-faceted structure, when the workpiece is turned over, the two slides on both sides of the top of the marble platform 1 15 is lowered, so that the telescopic rod 16 is lowered to both sides of the workpiece, and the clamping claws 161 are driven by the telescopic rod 16 to move toward the workpiece, so that both sides of the workpiece are clamped by the two clamping claws 161, and then the nut 131 is driven by the screw rod 13 to move upward until the workpiece has enough rotation space, and the telescopic rod 16 is driven by the rotating motor 162 to rotate the workpiece to rotate the reverse side, and then the turned workpiece is placed in the positioning fixture 12 for the next scanning; after the turning is completed, the position correction is performed again through software control, and the red light generator 30 fixed on the beam 22 emits red light through the galvanometer 301 to locate the PSD sensor module for scanning, and the PSD sensor module will transmit the signal to the computer after receiving the red light, and the computer will present the corresponding coordinate value through software calculation, and then the PSD sensor module value is read through the software, and the galvanometer motor position in the galvanometer 301 is fine-tuned to make the PSD sensor module reading reach the error range of the predetermined standard value, so as to complete the accurate size debugging.Then, the galvanometer is controlled by software to hit the left, right, upper and lower sensors. By adjusting the galvanometer 301PID, the PSD sensor module reading is within the error range of the preset standard value to complete precise dimensional debugging. After the calibrated 2D galvanometer system is tested on the treadmill for 10 minutes, 20 minutes, 30 minutes, 1 hour, and 2 hours, the PSD software will automatically collect the signal values ​​during this period, convert them into coordinate differences, and then derive the temperature drift value of the equipment through mathematical and statistical analysis by the software. A test report is automatically generated, including center error, dimensional deviation, and temperature drift. At the same time, after the scanning of the processed product is completed, the processed product can be clamped by the clamp 161 and then sent to the conveyor for transmission through an external manipulator to meet the needs of fully automatic production.
