Description

[0002] Metal sheets are widely used in fields such as automobile manufacturing, home appliance production, and architectural decoration. Using metal sheets can not only improve the appearance quality of products but also provide protection functions such as anti-corrosion, wear resistance, and weather resistance. The use of outer covers of metal sheets is also a commonly used technology in modern industrial design. When using metal sheets, it is necessary to process the base materials of the metal sheets. Surface treatment can improve the surface adhesion of the metal sheets and effectively improve the subsequent paint polishing effect.

[0035] When the present invention is used, the steps of the surface treatment process for the metal substrate include:

[0036] Step 1: Install and fix the fixing frame 1 to fix the entire device on the ground. The movement of the clamping component at the top is controlled by the first driving motor inside to move. The second servo inside the clamping component controls the clamping jaws 10 to clamp the metal plate body 8. During the clamping process, the air guide pipe 24 is inflated by an external air pump to make the inflatable clamping rubber pad 9 bulge outwards, and continuous inflation is obtained through the air guide pipe 24 to ensure the clamping force of the inflatable clamping rubber pad 9 and maintain the clamping action on the metal plate body 8. The angle of the metal plate body 8 at the bottom can be adjusted by controlling the rotating top plate 11 with the first servo.

[0037] Step 2: When the metal plate body 8 moves to the position of the polishing processing component, the second driving motor controls the lifting of the position of the polishing processing component, and the polishing roller 14 performs the polishing work on one side of the metal plate body 8. During the polishing process, the telescopic movement of the first electric push rod can adjust the position of the telescopic polishing block 15.

[0038] Step 3: After the polished metal plate body 8 is dried, the operator unloads it. Since the clamping component after unloading has metal material debris and metal plate oil stains adhered to the inflatable clamping rubber pad 9 during the polishing process, the cleaning component is used to clean the inflatable clamping rubber pad 9. When cleaning, first, the air guide pipe 24 sucks air to suck the inflatable clamping rubber pad 9 back into the clamping jaws 10 to be in a concave state. The second electric push rod 19 pushes the cleaning telescopic block 20 to the middle of the clamping component. The third electric push rod 25 pushes out the two cleaning brush heads 22 respectively and extends them into the concave positions of the corresponding inflatable clamping rubber pads 9. Driven by the third driving motor, the swinging brush block 27 performs a swinging cleaning action, and the cleaning brush heads 22 clean each inflatable clamping rubber pad 9. After cleaning, the inflatable clamping rubber pad 9 enters the next clamping and polishing process along with the clamping component.
