AI Technical Summary
The lids of existing wafer boxes are prone to jamming wafers, which increases the risk of wafer damage and affects safety during transportation and storage.
A novel wafer cassette was designed, employing an elastic block and positioning plate structure, combined with a low-friction coating and low-friction materials. Through the cooperation of the elastic block and positioning plate, the cassette cover is prevented from jamming the wafer. The elastic deformation of the elastic block and the low-friction coating reduce friction, ensuring that the wafer can be smoothly removed.
This effectively reduces the risk of wafers being damaged by being jammed by the casing cover, reduces economic losses, and improves safety during transportation and storage.

[0018] When the wafer 300 needs to be taken out, open the box cover 200 to move the box cover 200 upward by a distance, at this time the spring 5 returns to the original state so that the positioning plate 2 does not contact the upper part of the wafer 300, then press the pressing plate 3 downward, the spring 5 is elongated, the positioning plate 2 moves in the direction of the wafer inner box 1002 to push the wafer 300 clamped in the first clamping groove 2001 out to leave the wafer 300 in the wafer inner box 1002, avoiding the risk that the wafer 300 is taken up together with the box cover 200 and then falls to the ground and is broken, the elongated spring 5 returns to the original state, so that the positioning plate 2 returns to the original state under the action of the spring 5, and then the box cover 200 is completely opened to facilitate taking out the wafer 300 from the wafer inner box 1002, and the elastic block 1 has elasticity, so that the wafer 300 is more easily removed from the first clamping groove 2001 under the action of the positioning plate 2, avoiding the problem that the box cover 200 is easily clamped with the wafer 300, so as to greatly reduce the risk that the wafer 300 is damaged due to being clamped by the box cover 200, and reduce economic loss.
