AI Technical Summary
Existing anti-static material racks lack locking mechanisms, making them prone to falling off when stored in multiple layers or at an angle, thus reducing stability.
The electrostatic clamp adopts a combination structure of electrostatic basket, slotted plate, movable plate, ratchet and pawl. The synchronous pulley and lead screw drive the slider through belt to achieve stable locking of electrostatic clamp. The meshing of ratchet and pawl achieves self-locking, ensuring that the clamp is locked in a fixed position.
This improves the stability of the anti-static material rack, preventing circuit boards from loosening or falling due to vibration or external force during transportation and use, and ensuring that items are securely fixed.
