[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] In order to solve the problems in the prior art that the method of polishing a flexible glass plate using a contoured jig is high in cost and that the glass grinding amount is inconsistent and the yield is low due to uneven force on the glass, the utility model provides a polishing jig for a flexible non-planar glass plate, comprising: a base 4, on which a through hole 6 is provided; and a frame 2, which surrounds the base 4; wherein the side wall surface of the frame 2 and the top surface of the base 4 form a placement area for the glass to be polished, the polishing jig is configured to be able to extract air from the through hole 6 to make the glass to be polished fit the base 4, and the polishing jig is configured to be able to allow air to pass through the through hole 6 to separate the glass to be polished from the base 4.

[0030] like Figure 1 As shown, the surface shape of the base 4 can be set to be the same as the shape of the glass to be polished. The shape of the glass to be polished is determined by the shape designed by the vehicle display screen, such as a rectangle or other polygon. The base 4 can be made of abrasive (polyurethane) material. The frame 2 is set around the periphery of the base 4 and is higher than the base 4 to form a placement area for the glass to be polished. The glass to be polished can be partially embedded in the placement area for the glass to be polished. The height difference between the frame 2 and the base 4 is preferably in the range of 1 to 3 mm. The base 4 can be used to support the glass to be polished, and the frame 2 can be used to limit the glass to be polished.

[0031] The through hole 6 on the base 4 passes through the top and bottom surfaces of the base 4 so as to extract the air between the glass to be polished and the base 4 so that the glass to be polished and the base are fitted together and flattened. In the subsequent polishing process, the glass is evenly stressed and the yield is high. Moreover, when air is introduced into the through hole 6 again, the glass to be polished is separated from the base 4. Since the flexible glass plate of this solution can be restored to its original state, this solution does not change the product structure.

[0032] Compared with the existing method of polishing flexible glass plates using a contoured jig, the solution of the present application has a low manufacturing cost and a short processing and production cycle. In addition, since a through hole 6 for sucking the product flat is provided on the base 4, the product surface is subjected to uniform force during polishing, the glass grinding amount is consistent, and the yield is high.

[0033] In some embodiments, the length of the base 4 is set to 500 mm to 1000 mm. Figure 3 As shown, the flexible glass plate needs to meet certain size requirements to avoid breakage during the flattening process. Combined with the size of the lower plate 1, the length of the glass to be polished applicable to the jig of the present application can be 500 mm to 1000 mm. In addition, the inclination angle of the glass to be polished applicable to the jig of the present application can be 0 degrees to 75 degrees, and the inclination angle here is set to the angle between the cut surface of the side of the flexible glass plate in the over-bent state and the horizontal plane.

[0034] In some embodiments, there are multiple through holes 6, and multiple through holes 6 are arranged at the ends of the base 4. When the glass to be polished is flattened, it can be placed with the concave surface facing upwards, and then vacuum is drawn through the multiple through holes 6 arranged at both ends of the base 4, so that both ends of the glass are adsorbed and attached to the top surface of the base 4; it can also be placed with the concave surface facing downwards, and first one end of the glass is adsorbed and attached to the base 4 using the through holes 6, and then the other end of the glass is adsorbed and attached to the base 4. Therefore, the through hole 6 can be arranged at the end of the base 4. When the length of the glass to be polished is long, the through hole 6 can also be opened in the middle of the base 4.

[0035] In some embodiments, the through hole 6 is configured as a T-shaped hole. Figure 1 and 3 As shown, the through hole 6 is set as a T-shaped hole, which can facilitate the quick absorption of the glass to be polished in both the length and width directions. The through hole 6 can also be a cross-shaped hole.

[0036] In some embodiments, a damping cloth 5 is laid on the base 4 to reduce the friction between the glass to be polished and the base 4. Figure 1 and 3 As shown, in order to further ensure the yield of the product during the production process, a damping cloth 5 needs to be attached to the top surface of the base 4 to prevent defects caused by friction between the product and the base 4. The damping cloth 5 can cover the entire top surface of the base 4.

[0037] In some embodiments, the frame 2 is a scraper strip. The wear-resistant scraper strip is used to protect the side of the glass to be polished, thereby isolating and protecting the chamfer and the straight part of the glass to be polished during the polishing process.

[0038] On the other hand, the utility model provides a polishing machine, comprising: the aforementioned polishing jig for flexible non-planar glass plates; a lower plate 1 on which the polishing jig is arranged; and an upper plate arranged above the lower plate 1.

[0039] like Figure 1 As shown, the lower plate 1 can be a round aluminum plate for supporting and fixing the polishing jig, and the upper plate can be a grinding plate for rubbing and polishing the surface of the glass to be polished. During the production process, the upper plate is moved above the polishing jig and is close to the upper surface of the glass to be polished. The upper plate and the lower plate 1 rotate in opposite directions to achieve relative movement and rub and polish the glass to be polished.

[0040] In some embodiments, the upper surface of the lower plate 1 is provided with an isolation layer 3, and the isolation layer 3 is abrasion dermabrasion. Figure 2 As shown, the upper surface of the lower plate 1 can be glued with an isolation layer 3, and the base 4 can also be glued to the isolation layer 3 to prevent aluminum chips from being generated during the production process from causing damage to the polished glass. The isolation layer 3 can be made of abrasive (polyurethane) material.

[0041] In some embodiments, there are multiple polishing jigs on the lower plate 1, and the multiple polishing jigs are arranged at equal intervals. Figure 1 and 3 As shown, the number of polishing jigs is determined by the size of the glass to be polished, and is generally 1 to 3. In addition, each polishing jig of the present application can directly turn over the glass to be polished during the production process, without the need for the existing profiling jig to turn over the glass during the production process and move it to a profiling jig of another shape for polishing.

[0042] In some embodiments, there are multiple lower discs 1, and each lower disc 1 corresponds to an upper disc. The polishing machine of the present application has multiple lower discs 1 and multiple upper discs corresponding to the lower discs 1. In some specific embodiments, each polishing machine can be provided with 3 to 5 lower discs 1 and 3 to 5 upper discs. The shape and area of ​​the lower disc 1 can be the same as those of the upper disc.

[0043] So far, various embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

[0044] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
