Description

Technical Field

[0001] This utility model relates to the field of 3D glass processing technology, specifically to a 3D glass concave surface cleaning fixture. Background Technology

[0002] Polishing is an essential process in the production of glass covers, used to polish the glass surface. PVC is commonly used to make polishing fixtures, ensuring a smooth and uniform surface finish. However, during polishing, the prolonged rotation and friction of the polishing brushes can cause the PVC fixture to wear down, deform, and collapse. This leaves the curved edges of the 3D glass exposed without fixture protection, resulting in the edges of the 3D glass being higher than the fixture. This can easily lead to issues like excessive curvature and chipping / cracking of the 3D glass. Furthermore, the fixture needs to be replaced promptly after wear, resulting in low efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a 3D glass concave surface cleaning fixture.

[0004] The purpose of this utility model is achieved through the following technical solution: a 3D glass concave surface cleaning fixture, including a fixture body, a groove for placing 3D glass is opened in the middle of the top of the fixture body, an annular rectangular groove is opened around the top of the fixture body corresponding to the groove, an annular metal strip is embedded in the annular rectangular groove, the top surface of the annular metal strip is higher than the top surface of the fixture body, and the top surface of the placed 3D glass is flush with the top surface of the annular metal strip.

[0005] Furthermore, a vacuum adsorption tank is provided on the bottom surface of the tank, and an air extraction hole is provided in the middle of the bottom of the vacuum adsorption tank, penetrating the upper and lower surfaces of the fixture body.

[0006] Furthermore, the tank shown is a rounded rectangle, and the vacuum adsorption tank is in the shape of a grid.

[0007] Furthermore, the distance between the top surface of the annular metal strip and the top surface of the fixture body is 0.15-0.25 mm.

[0008] Furthermore, the distance between the top surface of the annular metal strip and the top surface of the fixture body is 0.2 mm.

[0009] Furthermore, the top surface of the 3D glass protrudes beyond the top surface of the annular metal strip after placement.

[0010] Furthermore, the distance between the top surface of the placed 3D glass and the top surface of the annular metal strip is 0.05-0.15mm.

[0011] Furthermore, the distance between the top surface of the placed 3D glass and the top surface of the annular metal strip is 0.1 mm.

[0012] The beneficial effects of this utility model are as follows: The 3D glass concave surface polishing fixture of this utility model has an annular rectangular groove opened around the top of the fixture body corresponding to the groove, and an annular metal strip is embedded in the annular rectangular groove. This can increase the wear resistance of the fixture body, improve the efficiency of the fixture, and reduce the cost. The strength of the annular metal strip can more effectively protect the arc edge and arc height of the glass from being defective due to deformation and collapse of the fixture during the polishing process, thereby improving the product yield.

[0017] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-3 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] See Figure 1-3 A 3D glass concave surface cleaning fixture includes a fixture body 1. A groove 12 for placing 3D glass 11 is opened in the middle of the top of the fixture body 1. A ring-shaped rectangular groove 13 is opened around the top of the fixture body 1 corresponding to the groove 12. A ring-shaped metal strip 14 is embedded in the ring-shaped rectangular groove 13. The top surface of the ring-shaped metal strip 14 is higher than the top surface of the fixture body 1. The top surface of the placed 3D glass 11 is flush with the top surface of the ring-shaped metal strip 14.

[0019] The 3D glass concave surface polishing fixture of this utility model has an annular rectangular groove 13 opened on the top of the fixture body 1 around the groove 12, and an annular metal strip 14 embedded in the annular rectangular groove 13. This can increase the wear resistance of the fixture body 1, improve the efficiency of the fixture, and reduce the cost. The strength of the annular metal strip 14 can more effectively protect the arc edge and arc height of the glass from being defective due to deformation and collapse of the fixture during the polishing process, thereby improving the product yield.

[0020] In this embodiment, a vacuum adsorption tank 15 is provided on the bottom surface of the tank body 12, and an air extraction hole 16 penetrating the upper and lower surfaces of the fixture body 1 is provided in the middle of the bottom of the vacuum adsorption tank 15. The above structure is designed to adsorb the 3D glass 11 and prevent it from shifting during the polishing process.

[0021] In this embodiment, the groove 12 is a rounded rectangle, and the vacuum adsorption groove 15 is in the shape of a grid. The shape of the groove 12 matches the convex surface of the 3D glass 11, which facilitates the placement of the 3D glass 11.

[0022] In this embodiment, the distance between the top surface of the annular metal strip 14 and the top surface of the fixture body 1 is 0.15-0.25 mm. This distance ensures that the polishing brush does not contact the top surface of the fixture body 1. To achieve the best performance of this invention, the distance between the top surface of the annular metal strip 14 and the top surface of the fixture body 1 is 0.2 mm.

[0023] Another preferred embodiment of this utility model is as follows: the top surface of the placed 3D glass 11 protrudes beyond the top surface of the annular metal strip 14. Specifically, the distance between the top surface of the placed 3D glass 11 and the top surface of the annular metal strip 14 is 0.05-0.15 mm. This distance ensures that the polishing brush does not contact the top surface of the fixture body 1. To achieve the best performance of this utility model, the distance between the top surface of the placed 3D glass 11 and the top surface of the annular metal strip 14 is 0.1 mm.

[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
