[0023] Please refer to Figures 1-4 , the technical solution provided by the present utility model:

[0024] A wafer storage bracket, comprising: a storage rack 1; a plurality of support plates 2 are uniformly and fixedly connected to the inner wall of the storage rack 1, a plurality of wafer placement boxes 3 are uniformly placed on the support plates 2, a plurality of sliding plates 4 are respectively movably arranged on the upper surfaces of the plurality of support plates 2, and each sliding plate 4 is correspondingly arranged on the lower surface of each wafer placement box 3 for supporting the wafer placement box 3, a plurality of guide rods 5, and each guide rod 5 is respectively correspondingly arranged inside each sliding plate 4, and one end of the guide rod 5 is fixedly connected to the inner wall of the storage rack 1;

[0025] Specifically, the storage rack 1 provided in the wafer storage bracket can limit a plurality of support plates 2, and the plurality of support plates 2 are arranged in upper and lower layers. The plurality of sliding plates 4 can be supported by the support plates 2. The wafer placement boxes 3 are placed on the provided sliding plates 4. A plurality of slots for storing wafers are opened inside the wafer placement boxes 3, so that each wafer can be stored vertically. When an operator takes the wafer placement box 3, the sliding plate 4 can be pulled outward. At the same time when the operator pulls the sliding plate 4, the movement position of the sliding plate 4 on the support plate 2 can be limited by the guide rod 5. When the sliding plate 4 is pulled outward, the wafer placement box 3 can be pulled to the outside of the storage rack 1, which is convenient for the operator to take the wafer placement box 3. At the same time, it can also prevent the wafer placement box 3 located on the adjacent sliding plate 4 from accidentally touching and falling when the wafer placement box 3 is taken, thereby improving the safety during the use of the present application and reducing the production loss caused by wafer damage;

[0026] Furthermore, it should be noted that the storage rack 1 is composed of a U-shaped rack and a plurality of moving wheels fixedly installed on the lower surface of the U-shaped rack. The installation position of the plurality of support plates 2 can be limited by the U-shaped rack, and the plurality of provided moving wheels can facilitate the operator to control the movement of the U-shaped rack, thereby enabling the transportation of the stored wafers.

[0027] In order to limit the movement position of the sliding plate 4 on the support plate 2 and prevent the support plate 2 from falling off, a limit block 6 is fixedly connected to the end of the guide rod 5 away from the storage rack 1, and the limit block 6 is located inside the sliding plate 4.

[0028] In order to limit the position of the wafer placement box 3 on the sliding plate 4 and improve the stability of the wafer placement box 3 when placed, a rectangular limit frame 7 is fixedly connected to the upper surface of the sliding plate 4, and the wafer placement box 3 is located inside the rectangular limit frame 7.

[0029] In order to reduce the friction between the sliding plate 4 and the support plate 2 when the sliding plate 4 moves, a plurality of placement holes 8 are uniformly opened on the upper surface of the support plate 2, a ball 9 is arranged inside the placement hole 8, and the side of the ball 9 away from the placement hole 8 is in contact with the lower surface of the sliding plate 4.

[0030] In order to prevent the slide plate 4 from moving randomly on the support plate 2 when supporting the wafer placement box 3, a plurality of storage grooves 10 are evenly opened inside the end of the support plate 2 away from the storage rack 1. The number of the plurality of storage grooves 10 matches the number of the plurality of slide plates 4. A snap-fit assembly 11 is arranged inside the storage groove 10. A snap-fit groove 12 is opened on the lower surface of the slide plate 4. The top end of the snap-fit assembly 11 is located inside the snap-fit groove 12.

[0031] In order to facilitate the control of the slide plate 4 to drive the wafer placement box 3 to move outward, a push plate 14 is fixedly connected to the side of the rectangular limit frame 7 close to the storage rack 1, and a pop-up component 13 is arranged between the side of the push plate 14 away from the rectangular limit frame 7 and the inner wall of the storage rack 1.

[0032] The clamping assembly 11 includes: an L-shaped clamping strip 1101 located inside the storage slot 10, a first spring 1102 is elastically connected to the lower surface of the L-shaped clamping strip 1101, a top end of the L-shaped clamping strip 1101 is located inside the clamping slot 12, and a pressing plate 1103 is fixedly connected to one end of the L-shaped clamping strip 1101 away from the clamping slot 12;

[0033] Specifically, when the slide plate 4 is pushed into the storage rack 1, the L-shaped card strip 1101 can be controlled to move upward under the elastic force of the first spring 1102, and the top end of the L-shaped card strip 1101 can be inserted into the inside of the clamping groove 12, so as to limit the position between the support plate 2 and the slide plate 4, and prevent the slide plate 4 from moving freely on the support plate 2 when supporting the wafer placement box 3. When it is necessary to control the movement of the slide plate 4, the operator can control the pressing plate 1103 to press downward. When the pressing plate 1103 is pressed, the L-shaped card strip 1101 can be controlled to move downward. When the L-shaped card strip 1101 moves downward, the first spring 1102 can be squeezed to contract, and at the same time, the top end of the L-shaped card strip 1101 can be controlled to disengage from the clamping groove 12.

Through the cooperation between the extension tube 1301, the limiting rod 1302 and the push plate 14, the movement of the rectangular limiting frame 7 can be guided, enhancing the stability of the rectangular limiting frame 7.

[0036] Brief description of the usage process:

[0037] During use:

[0038] Process step 1, wafer loading: Carefully place the wafers one by one into the wafer placement box 3, and place the multiple wafer placement boxes 3 loaded with wafers into the rectangular limiting frames 7 on different sliding plates 4 respectively, thus completing the wafer loading.

[0039] Process step 2, wafer storage: Push the sliding plate 4 together with the wafer placement box 3 into the storage rack 1. While pushing the sliding plate 4, the rectangular limiting frame 7 can squeeze the ejection component 13 to contract. After the sliding plate 4 is completely pushed in, the L-shaped clamping strip 1101 will move upward under the elastic force of the first spring 1102 and insert into the clamping groove 12, thus fixing the position of the sliding plate 4 and preventing it from moving randomly on the support plate 2, and completing the wafer storage.

[0040] Process step 3, wafer retrieval: The operator presses the pressing plate 1103 to control the L-shaped clamping strip 1101 to move downward and disengage from the clamping groove 12. At this time, the sliding plate 4 is no longer fixed. Under the elastic force of the second spring 1303, the sliding plate 4 can drive the wafer placement box 3 to slide outward and move to the outside of the storage rack 1. The operator can conveniently remove the wafer placement box 3 from the sliding plate 4 without worrying about accidentally touching and causing other wafer placement boxes 3 to fall.

[0041] Through the operations of process step 1, process step 2, and process step 3, the wafers can be well protected during storage and retrieval, reducing production losses caused by wafer damage and improving safety at the same time.
