Blanket for polishing 2.5 D cover plate

Abstract

The utility model discloses a blanket for polishing a 2.5 D cover plate, which comprises the 2.5 D cover plate and a blanket for polishing the 2.5 D cover plate, the central part of the 2.5 D cover plate is a plane, the edge part of the 2.5 D cover plate is subjected to radian treatment to enable the edge of the 2.5 D cover plate to be a cambered surface, and the blanket is lengthened to be capable of extending to the cambered surface of the 2.5 D cover plate for covering so as to ensure that in the polishing process, the surface of the 2.5 D cover plate is smooth. And the blanket is completely swept to the corresponding position, so that the problem of white edge leakage caused by the fact that the cambered surface position of the edge of the 2.5 D cover plate is not swept is solved.

Description

Technical Field

[0001] This utility model relates to the field of 2.5D cover plate polishing technology, and in particular to a 2.5D cover plate polishing blanket. Background Technology

[0002] After CNC machining, a 2.5D cover plate has a reserved grinding area at the edge for polishing. This is achieved by polishing with a blanket (grinding + buffing). When the blanket is used for the first time, the machine pressure is set to the optimal parameters. However, when the blanket is used for a long time and its length is insufficient, the pressure will be insufficient as the blanket shortens. This can result in the 2.5D cover plate's edge curvature not being swept, causing white edges to appear on the 2.5D cover plate. However, when adjusting the pressure, increasing the pressure will increase the grinding amount, which can easily make the total thickness of the cover plate too thin. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems existing in the prior art and provide a 2.5D cover plate polishing blanket.

[0004] To achieve the above objectives, the technical solution provided by this utility model is: a 2.5D cover plate polishing blanket, comprising a 2.5D cover plate and a blanket for polishing the 2.5D cover plate, wherein the central part of the 2.5D cover plate is flat, the edge part of the 2.5D cover plate is arc-shaped so that the edge of the 2.5D cover plate is arc-shaped, and the length of the blanket is extended to cover the arc-shaped surface of the 2.5D cover plate.

[0005] Preferably, the arc surface of the edge of the 2.5D cover plate is lower than the position of the viewing window area.

[0006] Preferably, the blanket is placed on the polishing disc of the rotary polisher, with the 2.5D cover plate facing the blanket. The beneficial effects of this invention are:

[0007] This invention extends the length of the polishing blanket to cover the curved surface of the 2.5D cover plate, ensuring that the blanket is fully swept to the corresponding position during the polishing process, thereby solving the problem of white edges caused by the blanking of the curved surface of the 2.5D cover plate.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0014] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0015] Reference Figures 1-2 In a preferred embodiment of this utility model, a 2.5D cover plate polishing blanket includes a 2.5D cover plate and a blanket for polishing the 2.5D cover plate. The central portion of the 2.5D cover plate is flat, and the edges of the 2.5D cover plate are curved, making the edges of the 2.5D cover plate arc-shaped. The length of the blanket is extended to cover the arc-shaped surface of the 2.5D cover plate. The arc-shaped edge of the 2.5D cover plate is lower than the viewing window area. The blanket is placed on the polishing disc of a rotary polisher, with the 2.5D cover plate facing the blanket.

[0016] Preferably, the rotary polishing machine is model XJ-1, with a voltage of 220V and a power of 1.5KW.
