Description

Technical Field

[0001] The present invention relates to the technical field of 3D glass, and in particular to a 3D glass polishing jig. Background Art

[0002] In the production process of 3D glass, the concave and convex surfaces of the 3D glass need to be polished separately first, and then the convex surface of the 3D glass needs to be anti-glare treated by AG chemical etching. Before chemical etching, in order to protect the concave surface of the 3D glass from being etched by chemical solutions, protective oil will be sprayed on the concave surface of the 3D glass. However, this process will also cause the protective oil to splash onto the straight body part of the convex surface of the 3D glass and the curved body part around the 3D glass. In order to facilitate the removal of the protective oil splashed on the convex surface of the 3D glass, the concave surface of the 3D glass is usually sprayed with protective oil first, and then the convex surface of the 3D glass is polished by a polishing machine. Therefore, a fixture is needed that can expose the convex surface of the 3D glass to the polishing brush and effectively isolate the concave surface of the 3D glass from the polishing brush. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a 3D glass polishing jig.

[0004] A 3D glass polishing jig is used to assist in polishing a 3D glass convex surface, comprising a jig body, the top of which has or can form a first profiling surface that can fit and adhere to a glass concave surface, and the top of the jig body has an annular surface. When the glass concave surface and the first profiling surface form an adaptable fit, the annular dividing surface between the glass concave surface and the convex surface fits and abuts against the annular surface.

[0005] Preferably, the fixture body includes a carrier plate, the top of the carrier plate has a groove body, a soft cushion layer is arranged in the groove body, the bottom wall of the groove body is a second contour surface of the glass concave surface, and a first flow channel connected to the groove body is opened on the carrier plate; forming the first contour surface that can fit with the glass concave surface specifically includes: placing the glass in the groove body, extracting the gas between the glass concave surface and the bottom wall of the groove body through the first flow channel, causing the cushion layer to deform between the glass concave surface and the second contour surface), so that the top surface of the cushion layer is shaped into the first contour surface that fits with the glass concave surface, and the annular dividing surface is sunk to fit with the annular surface.

[0006] Preferably, the cushion layer has a through groove running through from top to bottom, and the through groove is communicated with the first flow channel.

[0007] Preferably, the through groove includes a main through groove a located in the middle part of the cushion layer and distributed along the relative long side direction of the second profiling surface, and a plurality of branch through grooves b evenly distributed on the cushion layer and distributed along the relative wide side direction of the second profiling surface. The connection point between the through groove and the first flow channel is located in the center part of the main through groove a.

[0008] Preferably, a plurality of slits are provided on the upper surface of the cushion layer, one end of which is connected to the main through groove a or the branch through groove b, and the other end of which passes through the edge of the cushion layer.

[0009] Preferably, the carrier plate is further provided with a plurality of second flow channels connecting the slits, the annular surface, and the first flow channels.

[0010] Preferably, the fixture body has an inclined surface extending obliquely downward from the top of the annular surface to the outer peripheral surface of the fixture body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The concave surface of the 3D glass can be reliably supported on the first profiling surface, and the annular surface can not only limit the glass to prevent it from shifting during the polishing process, but also completely expose the convex surface of the 3D glass to the polishing brush, and isolate the concave surface of the 3D glass from the polishing brush, so that only the convex surface of the 3D glass is polished, and the vertical position of the concave surface of the 3D glass will not be polished, which effectively protects the protective oil of the vertical position of the concave surface of the 3D glass. Therefore, in the subsequent AG etching process, the chemical solution will not etch the vertical position of the concave surface of the glass, thereby ensuring the yield rate of 3D glass processing.

[0013] The soft cushion layer can provide shock absorption and protection for the concave surface of the 3D glass during the polishing process. The through grooves and slits on the cushion layer are more convenient for the discharge of gas in the fixture during vacuum adsorption, so that the center part and the body of the 3D glass can be more firmly adsorbed to the cushion layer, and the cushion layer and the second contour surface on the carrier plate, and the cushion layer can more easily form a second contour surface that matches the concave surface of the 3D glass.

[0019] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 .3D glass polishing jig, used to assist in polishing the convex surface of 3D glass, including a jig body 1, the top of the jig body 1 has or can form a first contour surface 11 that can fit and fit with the glass concave surface 21, the top of the jig body 1 has an annular surface 12, when the glass concave surface 21 forms an adaptation fit with the first contour surface 11, the annular dividing surface 23 between the glass concave surface 21 and the convex surface 22 fits and fits against the annular surface 12.

[0021] The concave surface 21 of the 3D glass can be reliably supported downward on the first profiling surface 11, and the annular surface 12 can not only limit the 3D glass 2 to prevent it from shifting during the polishing process, but also completely expose the convex surface 22 of the 3D glass to the polishing brush, and isolate the concave surface 21 of the 3D glass from the polishing brush, so that only the convex surface 22 of the 3D glass is polished, and the vertical position of the 3D glass concave surface 21 is not polished, and the protective oil of the vertical position of the 3D glass concave surface is effectively protected, so that in the subsequent AG etching process, the chemical solution will not etch the vertical position of the glass concave surface 21, thereby ensuring the yield rate of 3D glass processing.

[0022] Reference Figure 1-Figure 5 The fixture body 1 includes a carrier plate 10, the top of the carrier plate 10 has a groove body 13, a soft cushion layer 3 is arranged in the groove body 13, the bottom wall of the groove body 13 is a second profiling surface 14 of the glass concave surface 21, and the carrier plate 10 is provided with a first flow channel 15 connected to the groove body 13; forming the first profiling surface 11 that can fit with the glass concave surface 21 specifically includes: placing the glass 2 in the groove body 13, and extracting the gas between the glass concave surface 21 and the bottom wall of the groove body 13 through the first flow channel 15, so that the cushion layer 3 is deformed between the glass concave surface 21 and the second profiling surface 14, so that the top surface of the cushion layer 3 is shaped into the first profiling surface 11 that fits with the glass concave surface 21, and the annular dividing surface 23 sinks to fit with the annular surface 12.

[0023] The soft cushion layer 13 can provide shock absorption and protection for the concave surface 21 of the 3D glass during the polishing process. In practical applications, the soft cushion layer 13 can be made of damping cloth with good air permeability such as silk. The first flow channel 15 is connected to the vacuum adsorption hole on the lower working disk of the polishing machine, and the 3D glass is firmly positioned in the carrier 10 through vacuum adsorption.

[0024] In order to make the cushion layer 3 play a better buffering and shock absorbing role, the cushion layer 3 can be made of rubber material. At the same time, it does not affect the vacuum adsorption of the 3D glass. The gas passes through the cushion layer 3 and then discharged through the first flow channel 15. The cushion layer 3 has a through groove 31 running through the upper and lower parts, and the through groove 31 is connected to the first flow channel 15.

[0025] Reference Figure 2In order to make the cushion layer 3 deform evenly under force during vacuum adsorption of the 3D glass so that its top surface can more easily form the first profiling surface 11, the through groove 31 includes a main through groove 31a located in the middle of the cushion layer 3 and distributed along the relatively long side direction of the second profiling surface 14, and a plurality of branch through grooves 31b evenly distributed on the cushion layer 3 and distributed along the relatively wide side direction of the second profiling surface 14. The connection point between the through groove 31 and the first flow channel 15 is located in the center of the main through groove 31a.

[0026] In order to make the cushion layer 3 easier to deform, a plurality of slits 32 are provided on the upper surface of the cushion layer 3, one end of which is connected to the main through groove 31a or the branch through groove 31b and the other end passes through the edge of the cushion layer 3. When the cushion layer 3 is deformed, the slits 32 will crack.

[0027] In order to form a strong negative pressure adsorption between the first profiling surface 11 and the standing position of the 3D glass concave surface 21, a plurality of second flow channels 16 connecting the slits 32, the annular surface 12, and the first flow channel 15 are also provided on the carrier 10, so that when the carrier 10 is evacuated, the gas between the standing position of the glass concave surface 21 and the cushion layer 3 and the second profiling surface 14 can be discharged through the slits 32, the second flow channel 16, and the first flow channel 15. In actual applications, the second flow channel 16 can be made into an annular groove adjacent to the annular surface 12 and a plurality of branch flow channels located inside the carrier 10 and connected to the first flow channel 15.

[0028] In order to make the polishing brush more fully and easily contact the convex surface 22 of the 3D glass and ensure the polishing effect, the fixture body 1 has an inclined surface 17 extending obliquely downward from the top of the annular surface 12 to the outer peripheral surface of the fixture body 1. In actual applications, in order to increase the strength of the side of the inclined surface at the top of the annular surface 12 that abuts against the annular dividing surface 23 of the 3D glass and prevent it from collapsing, this part can be processed into a horizontal platform with a width between 0.2mm-0.3mm.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
