[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a circular cover plate edge polishing fixture 10 includes: a lower bottom plate 100, an upper clamping plate 200 and a positioning member 300; the upper clamping plate 200 and the lower bottom plate 100 are arranged at intervals to form a cover plate positioning area; the positioning member 300 includes a first positioning block 310 and a second positioning block 320. The first positioning block 310 and the second positioning block 320 are located on the cover plate positioning area, and a first positioning groove 311 is formed on the first positioning block 310, and a second positioning groove 321 is formed on the second positioning block 320. The first positioning groove 311 and the second positioning groove 321 respectively abut against the side wall of the cover plate 20.

[0025] It should be noted that the lower bottom plate 100 is installed on the lower workpiece shaft of the edge polishing equipment, and the upper clamping plate 200 is installed on the upper workpiece shaft of the edge polishing equipment. After the lower bottom plate 100 and the upper clamping plate 200 are installed on the edge polishing equipment, a cover plate positioning area will be formed between the lower bottom plate 100 and the upper clamping plate 200. The cover plate 20 is placed on the cover plate positioning area, and the lower bottom plate 100 is used to carry and limit the cover plate. In this way, the upper and lower surfaces of the cover plate can be clamped and limited by the lower bottom plate 100 and the upper clamping plate 200; at the same time, the side wall of the cover plate 20 is positioned by the first positioning block 310 and the second positioning block 320 located on the cover plate positioning area to ensure the accuracy of the placement position of the cover plate 20, so as to facilitate the subsequent edge polishing operation of the side edge of the cover plate 20, that is, the edge of the cover plate 20. Specifically, before the edge polishing operation of the cover plate 20, a plurality of cover plates 20 are stacked on the cover plate positioning area in sequence. At the same time, the first positioning groove 311 on the first positioning block 310 and the second positioning groove 321 on the second positioning block 320 respectively abut against the side wall of the cover plate 20, so that a plurality of cover plates 20 can be stacked neatly and evenly together to avoid mutual misalignment of each cover plate, and further ensure the accuracy of the edge polishing position of each cover plate 20. After the positioning of the cover plate 20 is completed, the edge polishing equipment can be used to drive the upper clamping plate 200 or the lower bottom plate 100 to move, so that the upper clamping plate 200 or the lower bottom plate 100 approach each other, thereby realizing the clamping and fixing of the cover plate 20. For example, a cylinder connected to the upper clamping plate 200 is installed on the edge polishing equipment, and the upper clamping plate 200 is driven by the cylinder to press and fix the cover plate; finally, after the clamping and positioning of the cover plate are completed, the positioning member 300 can be removed, and then the edge polishing equipment is used to perform a unified polishing operation on the edges of each cover plate 20. In this way, the consistency of the edge polishing effect of each cover plate 20 can be ensured, the operation is simple, and the production quality of the product is further stabilized;

[0026] In one embodiment, please refer toFigure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , a first card hole 110 and a second card hole 120 are formed in the lower base plate 100. A first card block 312 is provided at one end of the first positioning block 310 facing the lower base plate 100, and a second card block is provided at one end of the second positioning block 320 facing the lower base plate 100. The first card block 312 is received in the first card hole 110, and the second card block is received in the second card hole 120. Then, the first positioning block 310 and the second positioning block 320 can be limited by the first card hole 110 and the second card hole 120, so as to ensure the accuracy of the placement position of the cover plate 20 and improve the consistency of the edge polishing effect of the cover plate 20. It should also be noted that when the first positioning block 310 is inserted into the lower base plate 100, a first limiting groove is formed at one end of the first positioning block away from the lower base plate, and the first limiting groove is attached to the side wall of the upper clamping plate 200. Similarly, when the second positioning block 320 is inserted into the lower base plate 100, a second limiting groove is formed at one end of the second positioning block 320 away from the lower base plate 100, and the second limiting groove is attached to the side wall of the upper clamping plate 200. In another embodiment, the first card hole 110 and the second card hole 120 can also be provided on the upper clamping plate 200 to limit the first positioning block 310 and the second positioning block 320 through the upper clamping plate 200.

That is, both the lower base plate 100 and the upper clamping plate 200 are made of plastic material. Since the cover plate 20 is usually a glass cover plate 20, the lower base plate 100 and the upper clamping plate 200 need to be made of plastic material to reduce the risk of damaging the cover plate 20 by the lower base plate 100 or the upper clamping plate 200. Preferably, the lower base plate 100 is a red bakelite lower base plate 100, and the upper clamping plate 200 is a red bakelite upper clamping plate 200, that is, both the lower base plate 100 and the upper clamping plate 200 are made of red bakelite material. In another embodiment, in order to further avoid reducing the risk of the lower base plate 100 and the upper clamping plate 200 damaging the cover plate, a buffer sponge pad can be provided on the side surface of the lower base plate 100 facing the cover plate. Similarly, a buffer sponge pad is also provided on the side surface of the upper clamping plate 200 facing the cover plate.

[0030] In one embodiment, both the first positioning block 310 and the second positioning block 320 are plastic positioning blocks. Similarly, in order to reduce the risk of the first positioning block 310 and the second positioning block 320 damaging the cover plate 20, both the first positioning block 310 and the second positioning block 320 are made of plastic material. Preferably, both the first positioning block 310 and the second positioning block 320 are red bakelite positioning blocks, that is, both the first positioning block 310 and the second positioning block 320 are made of red bakelite material.

[0031] Preferably, the first positioning groove 311 and the second positioning groove 321 are in an arc-shaped structure. That is, the outer shapes of the first positioning groove 311 and the second positioning groove 321 are adapted to the outer shape of the circular cover plate 20, so as to further ensure the positioning accuracy of the circular cover plate 20, and at the same time ensure that the circular cover plates 20 are stacked neatly, thereby improving the consistency of the edge polishing effect of the circular cover plate 20.

[0032] Please refer to Figure 3 As shown, in one embodiment, a lower mounting hole 130 is formed on the lower base plate 100. Through the lower mounting hole 130, it is convenient to mount the lower base plate 100 on the edge polishing device. For example, a clamping block is provided on the lower workpiece shaft of the edge polishing device, and the lower base plate 100 is mounted and fixed by clamping the clamping block into the lower mounting hole 130; in another embodiment, bolts, screws and other screw connectors can also be used to realize the mounting and fixing of the lower base plate 100. In this embodiment, a plurality of lower mounting holes 130 are provided, and each of the lower mounting holes 130 is arranged around the central axis of the lower base plate 100. For example, three lower mounting holes 130 are provided. In this way, after the lower base plate 100 is mounted on the edge polishing device, the lower base plate 100 can be prevented from rotating.

[0033] In one embodiment, an upper mounting hole 210 is formed in the upper clamping plate 200.
