Description

Technical Field

[0001] This utility model relates to the field of precision grinding and polishing equipment, and in particular to a burr removal tool for grinding resin pads. Background Technology

[0002] In the field of precision grinding and polishing, grinding resin pads are a key consumable. Due to their excellent elasticity, wear resistance, and porous structure, they can effectively store and transport grinding slurry, making them widely used in high-precision surface treatment processes for semiconductor wafers, optical glass, and other materials. The grid groove design on the surface of the grinding resin pad is crucial for enhancing the flowability of the grinding slurry and timely removal of grinding debris, directly affecting the surface finish and polishing efficiency of the workpiece. Therefore, ensuring smooth, burr-free edges of the grid grooves is fundamental to guaranteeing the consistent performance and lifespan of the grinding resin pad.

[0003] However, during the manufacturing or finishing of polishing resin pads, irregular burrs often form on the top surface and sidewall edges of the grid grooves due to limitations in cutting or molding processes. If these burrs are not removed, they will not only affect the uniform distribution of the polishing slurry but may also scratch the surface of precision workpieces, leading to an increased defect rate. In existing technologies, the removal of burrs from grid grooves largely relies on manual removal and polishing by operators using handheld scrapers, sandpaper, or simple tools. This method is not only inefficient but also heavily dependent on personal experience, easily leading to incomplete burr removal or over-polishing that damages the groove structure. Especially for grid grooves with small spacing, manual operation makes it difficult to ensure the consistency of burrs in both vertical and horizontal directions and surface smoothness, thus affecting the overall quality stability of the polishing resin pad.

[0004] Therefore, how to develop a burr removal tool for grinding resin pads that can efficiently remove burrs in both horizontal and vertical directions of the mesh groove and perform surface grinding, simplify the operation process, improve processing efficiency, and ensure consistent processing quality has become a technical problem that urgently needs to be solved by those in this field. Utility Model Content

[0005] The purpose of this invention is to provide a burr removal tool for grinding resin pads, which can efficiently remove burrs in both horizontal and vertical directions of the mesh groove and perform surface grinding in one integrated manner, simplifying the operation process, improving processing efficiency, and ensuring consistent processing quality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a burr removal tool for grinding resin pads, comprising a flat plate, a handle, and two vertical plates. The handle is fixedly connected to the top of the flat plate, and the front end of the flat plate is configured as a first wedge structure. The bottom of the first wedge structure is sharpened to form a horizontal burr removal blade. Two vertical plates are arranged at intervals along the length of the flat plate and located at the bottom of the flat plate. The spacing between the two vertical plates matches the grid groove spacing of the abrasive resin Pad. The front end of the vertical plates is sharpened to form a vertical deburring blade. The outer side of the vertical plate is provided with a first frosted surface, and the bottom of the flat plate, adjacent to the outer side of the vertical plate, is provided with a second frosted surface.

[0007] Preferably, a horizontal plate is fixedly connected to the top of the two vertical plates. The horizontal plate is integrally formed with the vertical plates and forms an n-shaped structure. The horizontal plate is fixedly connected to the flat plate.

[0008] Preferably, the front end of the vertical plate is provided with a second wedge structure, which is formed by removing the bottom corner portion of the front end of the vertical plate.

[0009] Preferably, the inclined side of the second wedge structure is provided with a third wedge structure, the inclined surface of the third wedge structure faces outward and the bottom is sharpened, and the sharpening directions of the third wedge structures of the two vertical plates are symmetrically arranged, so as to make the cutting edge of the vertical deburring blade fit against the side of the grid groove of the abrasive resin Pad.

[0010] Preferably, the inclined surface of the first wedge structure is located at the top, for making the cutting edge of the horizontal deburring blade fit against the top surface of the grid groove of the abrasive resin pad.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention utilizes a horizontal deburring blade formed by a first wedge-shaped structure at the front end of the flat plate and its bottom edge, combined with a vertical deburring blade formed by a second and third wedge-shaped structure at the front end of the vertical plate. This allows for simultaneous contact with the top and side surfaces of the grid groove, achieving integrated and continuous removal of burrs in both horizontal and vertical directions. After deburring, the groove wall and top surface are immediately polished using the first and second abrasive surfaces. This effectively improves the efficiency and consistency of deburring and surface finishing, simplifies the operation process, and reduces reliance on operator experience. Thus, while ensuring that the edges of the polished resin pad grid groove are smooth and undamaged, it significantly improves the stability of processing quality and the service life of the tool.

[0015] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] like Figure 1-4 As shown, a burr removal tool for grinding resin pads includes a flat plate 1, a handle 2 and two vertical plates 3. The handle 2 is fixedly connected to the top of the flat plate 1. The front end of the flat plate 1 is configured as a first wedge structure 4. The bottom of the first wedge structure 4 is sharpened to form a horizontal burr removal blade. Two vertical plates 3 are arranged at intervals along the length of the flat plate 1 and are located at the bottom of the flat plate 1. The spacing between the two vertical plates 3 matches the grid groove spacing of the abrasive resin Pad. The front end of the vertical plate 3 is sharpened to form a vertical deburring blade. The outer side of the vertical plate 3 is provided with a first frosted surface 5, and the bottom of the flat plate 1 is provided with a second frosted surface 6 in the area adjacent to the outer side of the vertical plate 3.

[0017] Specifically, the spacing between the two vertical plates 3 matches the grid groove spacing of the abrasive resin Pad, allowing the vertical plates 3 to be smoothly embedded and move along the grid groove, thereby effectively removing irregular burrs in the vertical direction of the groove wall.

[0018] Specifically, the first frosted surface 5 is used to polish the vertical inner wall of the grid groove after the vertical burrs are removed from the vertical plate 3; the second frosted surface 6 is used to polish and finish the top surface of the grid groove after the horizontal burrs are removed by the horizontal deburring blade.

[0019] Specifically, the handle 2 is mounted above the flat plate 1 for easy gripping and operation. In use, the operator holds the handle 2, smoothly places the tool into the grid groove, and pushes it forward. During this process, the horizontal and vertical deburring blades remove burrs in the horizontal and vertical directions respectively, while the first abrasive surface 5 and the second abrasive surface 6 immediately polish the deburred surface, achieving integrated deburring and polishing operations. This method is simple and highly efficient.

[0020] Specifically, a horizontal plate 7 is fixedly connected to the top of the two vertical plates 3. The horizontal plate 7 is integrally formed with the vertical plates 3 and forms an n-shaped structure. The horizontal plate 7 is fixedly connected to the flat plate 1.

[0021] Specifically, the front end of the vertical plate 3 is provided with a second wedge structure 8, which is formed by removing the bottom corner portion of the front end of the vertical plate 3.

[0022] Specifically, the inclined side of the second wedge structure 8 is provided with a third wedge structure. The inclined surface of the third wedge structure faces outward and is sharpened at the bottom. The sharpening directions of the third wedge structures of the two vertical plates 3 are symmetrically arranged to make the cutting edge of the vertical deburring blade fit against the side of the grid groove of the abrasive resin Pad.

[0023] Specifically, the second wedge structure 8 provides a wedge-shaped guide for the vertical deburring blade, increasing its effective area for cutting into and removing burrs. As the tool slides along the grid groove, the burr removal process is smoother and more continuous, thus significantly reducing cutting resistance and making the operation more labor-saving and efficient.

[0024] Specifically, the inclined surface of the first wedge structure 4 is located at the top, which is used to make the cutting edge of the horizontal deburring blade fit against the top surface of the grid groove of the abrasive resin Pad.

[0025] First, the operator needs to hold the handle 2 fixed to the top of the plate 1 and place the tool steadily into the grid groove of the grinding resin Pad, ensuring that the distance between the two vertical plates 3 matches the groove spacing of the grid groove, so that the vertical plates 3 can be smoothly embedded in the groove, preparing for subsequent deburring and polishing operations. Then, after the tool is in place, the operator smoothly advances the tool forward along the direction of the grid groove. During this process, the horizontal deburring blade at the bottom of the first wedge structure 4 at the front end of the plate 1 will fit against the top surface of the grid groove, effectively removing irregular burrs in the horizontal direction. Meanwhile, the vertical deburring blade formed by the second wedge structure 8 at the front end of the vertical plate 3 and the third wedge structure on it will fit tightly against the side of the grid groove, continuously cutting off burrs in the vertical direction, thereby achieving efficient deburring. Finally, as the tool is advanced, the first frosted surface 5 on the outer side of the vertical plate 3 will polish and repair the vertical inner wall of the grid groove after the vertical burrs are removed. At the same time, the second frosted surface 6 on the bottom of the flat plate 1 and the area adjacent to the outer side of the vertical plate 3 will polish the top surface of the grid groove after horizontal burr removal, so that burr removal and polishing are completed in one step, improving the surface smoothness. In its design, this invention utilizes a second wedge-shaped structure 8 at the front end of the vertical plate 3 to provide a wedge-shaped guide for the vertical deburring blade, increasing the effective area for cutting and removing burrs and reducing resistance during the advancement process. Simultaneously, the first wedge-shaped structure 4 ensures that the horizontal deburring blade always adheres to the top of the groove, further guaranteeing more effortless and stable operation, as well as the continuity and effectiveness of deburring. Furthermore, this invention can complete the removal of burrs in both the horizontal and vertical directions of the grid groove and surface polishing in one operation. The method is simple and easy to implement, significantly improving work efficiency and ensuring the consistency of the quality of the polishing resin pad.
