Description

Technical Field

[0001] The utility model relates to the technical field of wafer storage devices, in particular to a wafer anti-fouling storage device. Background Art

[0002] Existing wafer storage devices generally use separate wafer boxes for storage, or use wafer bins to store a batch of wafers closely together in the bin. The use of wafer boxes for storage greatly reduces work efficiency. When wafers need to be taken out, each wafer box needs to be opened in turn and the wafers therein need to be taken out, which is cumbersome. At the same time, for wafers to be dried with ink, it is easy to contaminate the wafer box. Although the wafer bin has a large storage capacity, the wafers are closely attached to each other. For wafers to be dried with ink in the ink curing process, it is easy for the tension of the ink to cause the wafers to be further attached, making it difficult to separate the wafers and very easy to cause wafer damage.

[0003] The Chinese patent with the document number CN216270544U discloses a wafer box storage device, which introduces a mechanical arm to complete the intelligent access action of the wafer box, greatly improving the accuracy of the access action, avoiding collisions during the access process of the wafer box, and preventing the wafer from being damaged. However, the working efficiency of the mechanical arm is low, which is not practical for occasions where wafers are frequently accessed, and is not conducive to the drying operation of wafers to be dried ink;

[0004] The Chinese patent with the document number CN213620948U discloses a storage device for wafer processing. Under the elastic force generated by the sleeve, the sleeve rod and the first spring, the pushing mechanism will squeeze and push the wafer body forward and make it stably stuck in the box body. This method is easy to cause the wafer to be further pressed together due to the tension of the ink, making it difficult to separate the wafer and easily causing the wafer to be damaged.

[0005] Therefore, how to design a wafer anti-fouling storage device to solve the problem that wafers with ink to be dried are easily contaminated by the container, the ink may cause tension and make it difficult to separate the wafers, causing damage to the wafers, and ensure work efficiency has become a problem to be solved.
