Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to a polishing fixture for a crater platform of unequal thickness 2D glass cover plates. Background Technology

[0002] The term "crater" refers to the raised shape of the camera hole on the glass cover of a mobile phone. Because the crater side of the mobile phone glass cover is higher than the surface, this type of glass cover is also called an unequal thickness 2D glass cover.

[0003] After AG sandblasting, these products require polishing of the crater plateau to achieve a combination of a smooth crater plateau and the remaining sandblasted surfaces. Therefore, a jig is needed to hold the product in place. However, existing jigs typically have cavities machined directly onto a single substrate. This type of jig is difficult to manufacture, has low precision in the cavities, provides poor product fixation, and is prone to failure if any part of it is damaged. Summary of the Invention

[0004] In order to solve the technical problems existing in the background art, the present invention proposes a polishing fixture for a volcano platform with unequal thickness 2D glass cover plate.

[0005] This invention proposes a polishing fixture for a crater platform of unequal thickness 2D glass cover plate, comprising: a bottom flat plate, a middle contour plate, and a clearance cover plate, wherein: The middle contour plate has contour holes designed to mimic the outline of a glass cover. The middle contour plate is fixed above the bottom flat plate, and the lower end of its contour holes is closed by the bottom flat plate to form a contour groove on its inner side. An air-proof cover is used to cover the top of the central contour plate, and the air-proof cover has air-proof holes for the crater on the air-proof glass cover.

[0006] Preferably, the cover plate is further provided with an inner groove and a suction cup installed in the inner groove. The cover plate is provided with a pressing hole at the bottom of the groove, and when the cover plate covers the middle contour plate, the suction cup is located inside the contour groove.

[0007] Preferably, the bottom of the suction cup is provided with a pressing post, which is located inside the pressing hole.

[0008] Preferably, the top of the pressing column is provided with a wear-resistant plate made of wear-resistant material, and the wear-resistant plate is flush with the surface of the air-proof cover plate.

[0009] Preferably, the inner peripheral wall of the vent hole is provided with an adhesive layer.

[0010] Preferably, the cover plate has a settling groove area, the bottom of the settling groove area has a through opening and a plug inserted into the through opening, the inner space of the plug forms a settling hole, one end of the plug has a flange, and the flange is submerged in the settling groove area; the adhesive layer is provided on the inner wall of the plug.

[0011] Preferably, the bottom flat plate, the middle contour plate, and the clearance cover are all circular toothed plates with grooves on their peripheral walls.

[0012] Preferably, multiple contour grooves are provided and arranged circumferentially.

[0013] Preferably, the bottom flat plate is provided with a positioning post that passes through the middle contour plate, and the clearance cover plate is provided with a positioning hole that matches the positioning post. When the positioning hole is fitted into the positioning post, the clearance cover plate is coaxial with the bottom flat plate, and the suction cup and the clearance hole are both located inside the contour groove.

[0014] Preferably, the positioning post is located at the center of the bottom plate.

[0015] In this invention, the bottom flat plate protects the bottom surface of the product from polishing during the polishing process. The middle contour plate and the bottom flat plate work together to form a contour groove, which fixes the product's position and prevents it from moving during polishing. The clearance cover plate shields the large surface area of ​​the product from polishing, allowing only the crater platform area inside the clearance holes to be polished, achieving a combination of a smooth crater platform and a sanded surface on the rest of the product. The combination of the bottom flat plate and the middle contour plate to form the contour groove structure facilitates grinding of the groove bottom and inner walls, thereby reducing processing difficulty. At the same time, it improves the fit accuracy between the contour groove and the product, enhances the product's fixation effect, and the bottom flat plate, middle contour plate, and clearance cover plate can all be replaced independently.

[0017] Reference Figure 1-5 The present invention proposes a polishing fixture for a crater platform of unequal thickness 2D glass cover plate, comprising: a bottom flat plate 1, a middle contour plate 2, and a clearance cover plate 3, wherein: The central contour plate 2 has contour holes 21 designed to mimic the outline of a glass cover. The central contour plate 2 is fixed above the bottom flat plate 1, and the lower end of the contour holes 21 is closed by the bottom flat plate 1 to form a contour groove on its inner side. A venting cover plate 3 is used to cover the central contour plate 2, and the venting cover plate 3 has vent holes 31 for venting the crater on the glass cover.

[0018] During polishing, the bottom flat plate 1 in the fixture is used to protect the bottom surface of the product from polishing. The middle contour plate 2 and the bottom flat plate 1 cooperate to form a contour groove, which is used to fix the position of the product so that it cannot move during polishing. The clearance cover plate 3 is used to shield the large surface of the product from polishing. Only the crater platform inside the clearance hole 31 is polished to achieve the combined effect of a smooth crater platform and a sanded surface on the rest of the product.

[0019] As can be seen from the above, in this invention, the bottom flat plate 1 protects the bottom surface of the product from being polished during the polishing process; the middle contour plate 2 and the bottom flat plate 1 cooperate to form a contour groove, which is used to fix the product position so that it cannot move during polishing; the clearance cover plate 3 shields the large surface of the product from polishing, and only the crater platform area inside the clearance hole 31 is polished, so as to achieve the combined effect of a smooth crater platform and a sanded surface on the rest of the product. Furthermore, the structural design of the contour groove formed by the bottom flat plate 1 and the middle contour plate 2 facilitates the grinding of the bottom and inner wall of the groove, thereby reducing the processing difficulty. At the same time, it improves the fitting accuracy between the contour groove and the product and improves the fixing effect on the product.

[0020] In addition, in this embodiment, the clearance cover 3 is also provided with an inner groove and a suction cup 4 installed in the inner groove. The clearance cover 3 is provided with a pressing hole 32 at the bottom of the groove. When the clearance cover 3 covers the middle contour plate 2, the suction cup 4 is located inside the contour groove. In use, the glass cover is placed in the contour groove, the clearance cover 3 is placed on top of the glass cover, and the crater on the glass cover is placed in the clearance hole 31. Then, the exposed crater port platform is polished using a polishing device. After polishing, the pressing hole 32 presses the suction cup 4 to hold the glass cover in the contour groove. Then, the clearance cover 3 is lifted to remove the glass cover in the contour groove, and a new glass cover is placed in the contour groove. Finally, the glass cover on the clearance cover 3 is removed, and the clearance cover 3 is placed back on the base plate for another round of polishing.

[0021] As can be seen from the above, the present invention provides an inner groove on the clearance cover plate 3, a suction cup 4 is provided in the inner groove, and a pressing hole 32 is provided at the bottom of the groove on the clearance cover plate 3. When the clearance cover plate 3 covers the bottom plate, the suction cup 4 is located inside the contour groove. The suction cup 4 is pressed through the pressing hole 32 so that the suction cup 4 can hold the glass cover plate placed in the contour groove. Then, when the clearance cover plate 3 is lifted, the glass cover plate in the contour groove is brought out of the contour groove along with the clearance cover plate 3, thereby saving replacement time and improving work efficiency.

[0022] Furthermore, in this embodiment, the bottom of the suction cup 4 is provided with a pressing post, which is located inside the pressing hole 32. Pressing down the pressing post causes the suction cup 4 to suck up the glass cover plate.

[0023] Furthermore, the top of the pressing column is provided with a wear-resistant plate 5 made of wear-resistant material, and the wear-resistant plate 5 is flush with the surface of the air-proof cover plate 3.

[0024] In addition, in this embodiment, the inner peripheral wall of the vent hole 31 is provided with an adhesive layer 7, so as to absorb the polishing powder entering the gap between the vent hole 31 and the crater, and avoid damage to the glass cover plate due to the powder entering the vent cover plate 3.

[0025] Specifically, the clearance cover 3 has a recessed area, the bottom of which has a through-hole and a plug 6 inserted into the through-hole. The inner space of the plug 6 forms a clearance hole 31. One end of the plug 6 has a flange that is submerged in the recessed area, allowing the recessed area to accommodate the flange so that it does not protrude above the surface of the clearance cover 3. An adhesive layer 7 is applied to the inner wall of the plug 6. After the product is placed in the contour groove, the plug 6 is first removed from the clearance cover 3, then the clearance cover 3 is replaced, and the crater of the product is allowed to exit through the through-hole. Then, the plug 6 is inserted into the through-hole from above the crater. This facilitates the replacement of the adhesive layer and prevents the adhesive layer from contacting the outer wall of the crater.

[0026] Furthermore, in this embodiment, the bottom flat plate 1, the middle contour plate 2, and the clearance cover plate 3 are all circular toothed plates with grooves on their peripheral walls. This allows the fixture to cooperate with a surface grinder. During the grinding operation, the fixture is placed in the surface grinder so that the grooves on the bottom flat plate, the middle contour plate 2, and the clearance cover plate 3 can mesh with the internal and external teeth of the surface grinder, thereby using the surface grinder to grind the exposed port platform of the crater.

[0027] Furthermore, in this embodiment, multiple contour grooves are provided and arranged circumferentially.

[0028] In this embodiment, the bottom flat plate 1 is provided with a positioning post 11 that passes through the middle contour plate 2, and the positioning post 11 is located at the center of the bottom flat plate; the clearance cover plate 3 is provided with a positioning hole 33 that matches the positioning post 11, and when the positioning hole 33 is fitted into the positioning post 11, the clearance cover plate 3 is coaxial with the bottom flat plate 1, and the suction cup 4 and the clearance hole 31 are both located inside the contour groove. The design of the positioning post 11 and the positioning hole 33 facilitates the quick assembly and disassembly of the clearance cover plate 3.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
