During the production process of glass, the glass generally needs to be roughly processed, such as cutting into specific shapes or additional frosting and polishing. During the processing, it needs to be clamped and positioned to ensure the accuracy of the operation.

For example, the patent with patent publication number CN220446420U discloses a glass processing table that is easy to position and clamp, which solves the problem in the prior art that the size of the glass to be processed is affected by the size of the glass to be processed, and the personnel need to adjust the positioning and clamping device inside the processing table to meet the requirements of adapting to the size of the processed glass. If it takes a long time to complete the adjustment of the processing table, it will increase the difficulty of operating the device for the personnel, thereby reducing the work efficiency of the personnel.

[0032] Specific implementation method in this embodiment: when it is necessary to perform secondary processing on the produced glass, the glass to be processed is placed on the upper surface of the carrier 1, and by starting the driving unit 4, the driving unit 4 simultaneously drives several racks 2 to move towards each other. When moving, the fixed seat 5 is located on the lower surface of the glass. When several movable plates 6 contact the side of the glass, the glass is pushed to the center position of the carrier 1, and the center position of the glass is aligned with the center position of the carrier 1, which is convenient for secondary processing of the glass. When the glass is located at the center position of the carrier 1, the rack 2 continues to move, and the movable plate 6 is pressed on the fixed seat 5 moves toward the fixed plate 12. At this time, the spring 11 is compressed. When the movable plate 6 moves, it drives the fixed rod 10 to slide in the waist-shaped groove 8 on the connecting rod 7. Since one end of the connecting rod 7 is fixed, when the fixed rod 10 slides in the waist-shaped groove 8, it drives the elastic pressing wheel 9 to move downward. The elastic pressing wheel 9 with elasticity presses the glass on the bearing platform 1, which is convenient for secondary processing of the glass. After the secondary processing of the glass is completed, the driving unit 4 drives the plurality of racks 2 to move in opposite directions. At this time, the tension of the spring 11 is released, and the movable plate 6 is pushed back to the starting position, and the processed glass can be removed.

[0033] It is worth noting that the number of the above-mentioned racks 2 is not limited, and the number of racks 2 can be set according to the shape of the glass. The above-mentioned glass can be round, square or regular polygonal and can be positioned and clamped by moving several racks 2. For irregular or rectangular glass, the positioning method is specifically introduced in the following embodiment.
