Description

Technical Field

[0001] This utility model relates to the field of wafer cassette opening technology, specifically a wafer cassette opening mechanism. Background Technology

[0002] A wafer is a silicon wafer used to fabricate silicon semiconductor circuits, and it is generally in the shape of a circular plate. To improve wafer loading efficiency and avoid environmental contamination during the wafer loading process, wafers are usually placed in a cassette. Batch loading of wafers is achieved by transferring the cassette. During the transfer process, the cassette cover remains locked. When loading wafers, the cover needs to be opened. The transfer platform of the cassette has limited space, and manual operation is restricted. The efficiency of manually opening the cover is low, which affects the wafer loading and inspection efficiency.

[0003] To address this problem, the present invention provides a wafer cassette opening mechanism. Utility Model Content

The opening assembly 300 is located on one side of the wafer cassette cover. The cover removal assembly can unlock and magnetically attach the wafer cassette cover, removing it from the wafer cassette to achieve the opening effect. The cover moving assembly 400 is connected to the overall frame 100 and the opening assembly 300. The cover moving assembly 400 drives the cover opening assembly 300 to move downwards or upwards, completing the opening or resetting of the wafer cassette. Before manual placement of the wafer cassette, the platform moving cylinder 204 resets, and the wafer cassette platform 201 moves to its original position. The operator places the wafer cassette according to the wafer cassette positioning pin 202.
