Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a splicing grinding pad and plate clamp. Background Art

[0002] Abrasive pads are indispensable tools in the processing of materials such as glass, ceramics, silicon wafers, and semiconductor wafers. When grinding larger materials, larger abrasive pads are required. However, larger massage pads are not convenient to install and use directly, and need to be spliced ​​from multiple small abrasive pads. The backs of these small abrasive pads are coated with adhesive to facilitate sticking them to the abrasive disc to form a continuous abrasive surface.

[0003] At present, the method used for installing larger grinding pads is for operators to splice these small grinding pads and attach them to the grinding disc to form a complete grinding pad. Since each grinding pad has an adhesive backing, once the splicing position is inaccurate during splicing, the adhesive backing will easily stick to the grinding disc and need to be torn off and re-adhered, which will affect the viscosity and integrity of the adhesive backing. In addition, it is often difficult for operators to complete the splicing of multiple grinding pads at one time, and splicing gaps or overall misalignment are prone to occur. Utility Model Content

[0004] The utility model provides a splicing grinding pad plate clamp, which can solve the problems in the prior art that a larger grinding pad is inconvenient to install and a small grinding pad is easy to be spliced ​​inaccurately.

[0005] According to the utility model, a splicing grinding pad and plate clamp comprises: a clamp body, one end surface of the clamp body is depressed downward to form a groove for the grinding pad to be placed, and the depth of the groove is lower than the thickness of the grinding pad.

[0006] Through the provision of the groove in the utility model, the operator can easily place and adjust the position of the grinding pad without causing inaccurate splicing due to the lack of limit.

[0007] By setting the depth of the groove in the utility model to be lower than the thickness of the grinding pad, it can be ensured that after the grinding pad is placed, the adhesive backing part will not directly contact the groove opening, thereby preventing the adhesive backing from adhering to the fixture.

[0008] Preferably, the groove is circular in shape.

[0009] In the utility model, the circular groove is arranged to match the shape of the grinding pad, thereby increasing the stability of the grinding pad in the fixture, reducing the problem of displacement or misalignment, and improving the accuracy of splicing.

[0010] Preferably, an anti-stick coating is provided on the bottom of the groove and the side walls of the groove.

[0011] In the utility model, an anti-stick coating is arranged in the groove to further prevent the adhesive backing of the grinding pad from sticking to the fixture, thereby improving the convenience and accuracy of operation and effectively preventing the adhesive backing from sticking and causing the stickiness of the grinding pad to decrease.

[0012] Preferably, through holes of equal size are provided in the groove and in the middle of the anti-stick coating.

[0013] In the utility model, through the provision of the through hole, when the disc of the grinding machine is an annular disc, it can also penetrate through the through hole, thereby achieving effective fixation and precise positioning of the hollow grinding pad, which helps to ensure the stability of the processing of the hollow grinding pad.

[0014] Preferably, one end of the anti-stick coating close to the groove opening extends horizontally to the edge of the end surface of one end of the clamp body close to the groove.

[0015] In the utility model, the anti-stick coating is extended to the edge of the clamp body to ensure that the edge of the grinding pad will not stick to the clamp during the process of putting in and taking out, and can prevent the backing glue from sticking to the clamp body due to excessive amount, thereby improving the convenience of operation.

[0016] Preferably, the material of the clamp body is hard engineering plastic.

[0017] In the utility model, the clamp body is made of hard engineering plastic material, so it can have good flatness, impact resistance and corrosion resistance, and is relatively light. In addition, the hard engineering plastic material will not scratch the grinding pad.

[0018] Preferably, the material of the anti-stick coating is silicone.

[0019] In the utility model, organic silicon is used as the anti-stick coating material, which has good anti-stick performance and high temperature resistance, thereby extending the service life of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0029] Example 1

[0030] like Figure 1-8 As shown, this embodiment provides a base for an assembled ladder cage, which includes a clamp body 100, and one end surface of the clamp body 100 is recessed downward to form a groove 110 for the grinding pad to be placed in, and the depth of the groove 110 is lower than the thickness of the grinding pad.

[0031] By providing the groove 110 in this embodiment, the operator can easily place and adjust the position of the grinding pad without causing inaccurate splicing due to the lack of limit.

[0032] By setting the depth of the groove lower than the thickness of the complete polishing pad in this embodiment, it can be ensured that after the complete polishing pad is placed, the adhesive backing part will not directly contact the groove opening, thereby avoiding adhesion of the adhesive backing to the fixture.

[0033] In this embodiment, the shape of the groove 110 is circular.

[0034] In this embodiment, the circular groove 110 is configured to match the shape of the polishing pad, thereby increasing the stability of the polishing pad in the fixture, reducing displacement or misalignment problems, and improving splicing accuracy.

[0035] In this embodiment, an anti-stick coating 120 is disposed on the bottom of the groove 110 and the sidewalls of the groove 110 .

[0036] In this embodiment, the anti-stick coating 120 is provided in the groove 110 to further prevent the adhesive backing of the polishing pad from adhering to the groove 120, thereby improving the convenience and accuracy of operation and effectively preventing the adhesive backing from adhering to reduce the viscosity of the polishing pad.

[0037] In this embodiment, through holes 130 of the same size are disposed at the middle of the groove 110 and the anti-stick coating 120 .

[0038] Through the provision of the through hole 130 in this embodiment, when the disc of the grinder is an annular disc, the hollow grinding pad can also be inserted through the through hole 130 to achieve effective fixation and precise positioning of the hollow grinding pad.

[0039] In this embodiment, one end of the anti-stick coating 120 close to the opening of the groove 110 extends horizontally to the edge of one end surface of the clamp body 100 close to the groove 110 .

[0040] In this embodiment, the anti-stick coating 120 extends to the edge of the clamp body 100 to ensure that the edge of the polishing pad will not stick to the clamp body 100 during the placement and removal process, thereby improving operational convenience and preventing excessive adhesive from sticking to the clamp body 100 and causing adhesive residue.

[0041] In this embodiment, the material of the clamp body 100 is hard engineering plastic.

[0042] In this embodiment, the clamp body 100 is made of hard engineering plastic material, so it has good integrity, impact resistance and corrosion resistance, and is relatively light. In addition, the hard engineering plastic material will not scratch the polishing pad.

[0043] In this embodiment, the material of the anti-stick coating 120 is silicone.

[0044] In this embodiment, organic silicon is used as the material of the anti-stick coating 120 , which has good anti-stick performance and high temperature resistance, thereby extending the service life of the clamp body 100 .

[0045] When the present embodiment is used, the complete polishing pad uses the fixture body 100 without a through hole, and the polishing pad with a hollow center uses the fixture body 100 with a through hole 130. The operator puts the small piece of polishing pad into the groove of the fixture body 100 with the adhesive facing upward. Since the depth of the groove 110 is lower than the thickness of the polishing pad and the inner surface is provided with an anti-stick coating 120, the polishing pad can move and adjust its position in the groove 110. Multiple polishing pads are spliced ​​in the groove 110 to form a complete polishing surface; the anti-stick coating 120 ensures that the position of each polishing pad can be easily adjusted during the splicing process, improving the accuracy and tightness of the splicing, and due to the presence of the anti-stick coating 120, the adhesive will not stick to the surface of the fixture body 100 or the groove 110. After the splicing is completed, the operator puts the fixture body 100 and the built-in polishing pad as a whole on the laminating machine, covers the adhesive, and cuts off the excess and unnecessary parts; since the adhesive is not damaged, the polishing pad can be firmly adhered to form a flat and continuous polishing surface. Take the fixture body 100 and the grinding pad covered with adhesive backing as a whole. The size of the adhesive backing after cutting is slightly larger than the grinding pad. After tearing off the release film, put it on the grinder and align it. When the grinding disc on the grinder is a round disc, you can use the fixture body 100 without the through hole 130. Here, a complete grinding pad is placed in the fixture. When the grinding disc on the grinder is an annular disc, use the fixture body with the through hole 130. Here, a hollow grinding pad is placed in the fixture. This ensures that the fixture body 100 is placed in the disc. Finally, slowly drop the grinding disc and press the grinding pad for some time. After it is fully fitted and shaped, you can check the fitting effect and use the grinder normally for processing.

[0046] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0047] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and implementation methods similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the scope of protection of the present invention.
