[0026] It also includes a controller and an alarm. The controller is used to control the operation of motor 1 5, motor 2 36, cylinder 12, laser transmitter 31, laser receiver 32 and the alarm.

[0027] Working principle: Place the computer housing plate 22 on the upper end of the rotating plate 2, and make the four right angles of the computer housing plate 22 just fit with the four L-shaped plates 3. Adjust the height of the slider 2 30 according to the height of the computer housing plate 22, so that the laser emitted by the laser emitter 31 just fits with the upper end surface of the computer housing plate 22, and the laser emitter 31 successfully receives the laser signal emitted by the laser emitter 31. Then use bolts to fix the slider 2 30 and the slide rail 2 29, start the motor 2 36, the motor 2 36 drives the screw rod 35 to rotate, and the screw rod 35 drives the slider 1 27 and the slide rail 1 26 to move, so that the laser emitter 31 sweeps across the entire upper end surface of the computer housing plate 22. During the detection process, if the laser receiver 32 cannot receive the laser signal emitted by the laser emitter 31, it means that the computer housing plate 22 has paint splattered paint protrusions, then the laser receiver 32 sends a signal to the controller, and the controller commands the alarm to work, thereby reminding the staff that the computer housing plate 22 is unqualified.

[0028] After the detection of the upper end surface of the computer housing plate 22 is completed, the cylinder 12 is started, and the cylinder 12 drives the pressure plate 15 to move downward, and the computer housing plate 22 is clamped by the pressure plate 15 and the rotating plate 2. Then the motor 15 is started, and the motor 15 drives the rotating plate 2 to rotate through the reducer 6, thereby driving the computer housing plate 22 to rotate. The rotating plate 2 drives the square frame 21 to rotate during the rotation process. Since the push rod 19 is against the square frame 21, the square frame 21 drives the push rod 19 to move horizontally during the rotation process. Since the distance between the sliding seat 17 and the square frame 21 remains unchanged, the distance between the magnifying glass 18 and the side of the computer housing plate 22 to be observed and inspected also remains unchanged, so that it is convenient for the staff to detect through the magnifying glass 18.
