The workpiece is limited by the limit plate to prevent the workpiece from being offset due to external factors, resulting in inaccurate positions of some workpieces during processing. The vacuum adsorption module is then started to adsorb and fix the workpiece, and the fixing ring is driven while the moving plate moves, and the cleaning brush is driven by the fixing ring.

When in use, the workpiece is placed at the position where the vacuum adsorption module needs to be fixed. At this time, the rotating plates on both sides of the mounting shell are rotated to drive the threaded rods through the rotating plates, thereby driving the moving plate, and then driving the connecting block, and then driving the limit plate through the connecting block.
