[0027] See also Figures 1 to 6 A wafer cassette stage system for automatically adjusting the position of a wafer cassette of the present invention comprises a stage 1, on top of which a wafer cassette 8 is placed; the wafer cassette 8 is used for placing wafers.

[0028] Specifically, the side wall of the wafer box 8 is detachably fixed to the top of the stage 1 through extrusion contact with the matching component 6 and the pushing component 10, so that the disassembly and installation of the wafer box 8 are convenient.

[0029] Specifically, the matching component 6 includes a slide groove 2, a cylinder 3, and a clamping plate 4; the slide groove 2 is embedded in the top of the loading platform 1, and the cylinder 3 is bolted inside the slide groove 2, and the moving end of the cylinder 3 is fixedly connected to the side wall of the clamping plate 4; a left receiving plate 5 and a right receiving plate 7 are fixedly connected to the left and right sides of the front end of the top of the loading platform 1 respectively; the cylinder 3 is connected to the external air source, and a position detection sensor 101 is fixedly connected to the top of the loading platform 1.

[0030] Specifically, a matching magnet is provided on the left receiving plate 5 and the right receiving plate 7, and the matching magnet and the magnet 17 are arranged close to each other with the same pole, so that when the magnet 17 approaches the left receiving plate 5 and the right receiving plate 7, the magnet 17 is pushed to move, so that the extrusion plate 14 moves away from the elastic airbag 15.

[0031] Specifically, the side walls of the wafer box 8 are in compression contact with the left receiving plate 5 and the right receiving plate 7; the pushing assembly 10 includes a cylinder 3, a clamping plate 4 and a groove 9; the groove 9 is embedded in the rear end of the top of the stage 1; and the cylinder 3 and the clamping plate 4 are arranged in the groove 9.

[0032] Specifically, the side wall of the wafer box 8 is provided with an installation cavity 11, and a push plate 12 is slidably connected in the installation cavity 11. The push plate 12 is fixedly connected to one end of a spring 13, and the other end of the spring 13 is fixedly connected to the inner wall of the installation cavity 11. The push plate 12 is fixedly connected to the extrusion plate 14, and an elastic airbag 15 is embedded in the side wall of the installation cavity 11. The elastic airbag 15 is connected to the limiting airbag 16, and the limiting airbag 16 is arranged on the inner wall of the wafer box 8.

[0033] Specifically, a magnet 17 is fixedly connected to the push plate 12 .

[0034] Specifically, the elastic airbag 15 and the limiting airbag 16 form a limiting component, and a plurality of limiting components are arranged in the installation cavity 11 .

[0035] Specifically, the wafer box 8 is placed on the stage 1, and then the cylinders 3 in the matching components 6 at the left and right ends are controlled to drive the clamping plates 4 to move. The two groups of clamping plates 4 contact the inner walls of the left and right ends of the wafer box 8 and push the wafer box 8 to move to the limited position. Then the air pressure of the cylinder 3 in the matching component 6 is maintained, and the cylinder 3 in the pushing component 10 is controlled to drive the clamping plates 4 to move. The clamping plates 4 push the wafer box 8 forward until it contacts the left receiving plate 5 and the right receiving plate 7. The air pressure is maintained after it is pushed until it can no longer be pushed forward. At this time, the operator observes whether the position detection sensor 101 is triggered to complete the positioning of the wafer box 8. When the wafer box 8 is close to the left receiving plate 5, the magnet 17 is close to the left receiving plate 5. Near the left receiving plate 5 and the right receiving plate 7, the magnet 17 is pushed to move, so that the squeezing plate 14 moves away from the elastic airbag 15, so that the elastic airbag 15 is restored, and then the elastic airbag 15 extracts the air in the limiting airbag 16, so that the limiting airbag 16 shrinks, and the limiting airbag 16 loses the contact restriction on the side wall of the wafer, which is convenient for wafer transfer; after waiting for the wafer to be taken away, reverse ventilation is performed to release the holding force of the cylinder 3 system in the matching component 6 and the pushing component 10, and the wafer box 8 is taken away. The squeezing plate 14 is reset with the assistance of the spring 13, and the squeezing plate 14 squeezes the elastic airbag 15 to make the limiting airbag 16 open outward, which is convenient for clamping the wafer in the wafer box 8 and improving the wafer box 8 when moving.
