Description

Technical Field

[0001] This utility model relates to the field of glass cover plate splitting technology, and in particular to a glass cover plate splitting fixture. Background Technology

[0002] Currently, smart products, including mobile phone cameras, smart wearables, and smart home appliances, all use glass covers with high transparency, high strength, scratch resistance, and impact resistance, especially glass covers with raised structures.

[0003] In the production of glass cover plates, multiple glass cover plates are typically formed onto a single piece of glass using molding technology. Then, a dicing technique is used to obtain multiple glass cover plates from the single piece of glass. Currently, the commonly used dicing technique involves laser cutting to create multiple glass cover plates of the required size. However, traditional dicing fixtures are prone to stress concentration during the dicing process, leading to glass cover plate breakage and wear, which affects the quality of the glass cover plates and production efficiency. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a glass cover plate cleaving fixture that can prevent the glass cover plate from breaking and wearing during the cleaving process.

[0005] This utility model provides a glass cover plate sharding fixture, comprising: a lower pressure plate with a limiting groove in its middle, the bottom of which is provided with a plurality of spaced-apart perforated grooves that penetrate the lower pressure plate; an upper pressure plate with a supporting boss on its surface facing the lower pressure plate, the supporting boss having a plurality of spaced-apart sharding bosses, the plurality of sharding bosses corresponding one-to-one with the plurality of perforated grooves; and an elastic element, one end of which is mounted on the supporting boss and the other end extending toward the lower pressure plate, the height of which is greater than the height of the sharding bosses.

[0006] Furthermore, a clearance groove is provided on the cleavage protrusion.

[0007] Furthermore, the projected area of ​​the support boss on the limiting groove is smaller than the area of ​​the limiting groove.

[0008] Furthermore, the elastic element is any one of a spring, a foam pad, or a rubber pad.

[0009] Furthermore, the elastic element is a stainless steel spring.

[0010] Furthermore, the glass cover plate shattering fixture also includes an abutment block, which is fixed to the side of the stainless steel spring facing the lower pressure plate.

[0011] Furthermore, the elastic coefficient of the stainless steel spring ranges from 0.5 N / mm to 2 N / mm.

[0012] Furthermore, the number of elastic elements is four, and they are evenly distributed around the support boss.

[0013] Furthermore, both the upper pressure plate and the lower pressure plate are made of bakelite.

[0014] Furthermore, clearance grooves are provided at the four corners of the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) By setting an elastic element between the lower pressure plate and the upper pressure plate, and the elastic element protruding from the surface of the split boss used to support the glass cover plate, the elastic element provides a certain buffer to the glass cover plate when the lower pressure plate and the upper pressure plate are closed, so as to prevent the glass cover plate from being broken and worn.

[0017] (2) By setting a relief groove on the cracked protrusion of the glass cover plate, the protrusion on the glass cover plate can be extended into the relief groove, thus avoiding stress on the protrusion and ultimately causing the glass cover plate to crack. Attached Figure Description

[0026] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Figure 1 This is an exploded view of the glass cover plate splitting fixture provided by this utility model. To facilitate understanding of this solution, a whole piece of glass 4 is added between the upper pressure plate 2 and the lower pressure plate 1, wherein the whole piece of glass 4 contains multiple glass cover plates 41. Figure 2 This is a schematic diagram of the structure of the lower pressure plate 1 provided by this utility model. Figure 3 This is a schematic diagram of the structure of the upper pressure plate 2 and the elastic element 3 provided by this utility model.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a glass cover plate cracking fixture, including a lower pressure plate 1, an upper pressure plate 2, and an elastic element 3. The elastic element 3 is installed between the lower pressure plate 1 and the upper pressure plate 2. The lower pressure plate 1 and the upper pressure plate 2 are closed to clamp the entire piece of glass 4 located between them, that is, to clamp the glass cover plate 41. Among them, when the lower pressure plate 1 and the upper pressure plate 2 are closed, the elastic element 3 plays a role in buffering the compressive force between them, preventing the glass cover plate 41 from being subjected to excessive compressive force and cracking or wear.

[0029] Specifically, the lower pressure plate 1 has a rectangular bowl-shaped structure with a limiting groove 11 in the middle. Multiple spaced perforated grooves 12 are provided at the bottom of the limiting groove 11, penetrating the lower pressure plate 1. The upper pressure plate 2 has a supporting boss 21 on its surface facing the lower pressure plate 1. Multiple spaced splitting bosses 22 are provided on the supporting boss 21, corresponding one-to-one with the multiple perforated grooves 12. The splitting bosses 22 can support a whole piece of glass 4 with multiple glass cover plates 41, facilitating the splitting operation of the glass cover plates 41 and ensuring the setting accuracy of the glass cover plates 41. The perforated grooves 12 allow the glass cover plates 41 to be removed after the splitting operation. Preferably, the support boss 21 is set in the limiting groove 11 and the splitting boss 22 is one-to-one with the hollow groove 12 and set close to each other, so that one splitting boss 22 corresponds to one glass cover plate 41 and one hollow groove 12, so that the lower pressure plate 1 and the upper pressure plate 2 can clamp and fix the glass cover plate 41, and at the same time control the splitting operation of each glass cover plate 41.

[0030] One end of the elastic element 3 is mounted on the support boss 21, and the other end extends toward the lower pressure plate 1. The height of the elastic element 3 is greater than the height of the split boss 22, ensuring that the elastic element 3 protrudes from the surface of the split boss 22 near the lower pressure plate 1. By setting the elastic element 3 between the upper pressure plate 2 and the lower pressure plate 1, and ensuring that the height of the elastic element 3 is greater than the split boss 22 used to support the entire glass 4, the elastic element 3 first acts as a support and buffer when the lower pressure plate 1 and the upper pressure plate 2 are closed and close together. This prevents the lower pressure plate 1 and the upper pressure plate 2 from acting directly on the entire glass 4, thus preventing the glass cover plate 41 from being subjected to excessive compressive force and resulting in cracking and wear.

[0031] In one embodiment, the cleaving boss 22 is provided with a clearance groove 221. The clearance groove 221 is used to accommodate the protruding structure on the glass cover plate 41, preventing the protruding structure from being squeezed and worn during the cleaving process, thus affecting the quality of the product. It should be noted that the protruding structure on the glass cover plate 41 has high precision, and if there is a large amount of pressure during the cleaving process, it is easy to wear, which may lead to the scrapping of the glass cover plate 41. Therefore, it is necessary to provide a clearance groove 221 to protect the protruding structure on the glass cover plate 41.

[0032] In one embodiment, the projected area of ​​the support boss 21 on the limiting groove 11 is smaller than the area of ​​the limiting groove 11, ensuring that the support boss 21 can be placed into the limiting groove 11, so that the lower pressure plate 1 and the upper pressure plate 2 can press and fix the thinner whole piece of glass 4.

[0033] In one embodiment, the elastic element 3 is any one of a spring, a foam pad, or a rubber pad.

[0034] In one embodiment, the elastic element 3 is a stainless steel spring 31. The stainless steel spring 31 is a type of elastic element made primarily of stainless steel, possessing excellent corrosion resistance, high-temperature resistance, and non-magnetic properties. Using a stainless steel spring 31 for the elastic element 3 can improve the service life and cleaving accuracy of the glass cover plate cleaving fixture, while reducing production costs.

[0035] Based on the above solution, the glass cover plate cleaving fixture also includes an abutment block 32. The abutment block 32 is square in shape and is fixed to the side of the stainless steel spring 31 facing the lower pressure plate 1. That is, by setting the abutment block 32 at the end of the stainless steel spring 31 that contacts the lower pressure plate 1, the accuracy of the contact between the two is ensured, thereby improving the accuracy of cleaving.

[0036] Based on the above scheme, the elastic coefficient of the stainless steel spring 31 is in the range of 0.5N / mm-2N / mm, so that the stainless steel spring 31 can provide sufficient elastic force to buffer the closing of the lower pressure plate 1 and the upper pressure plate 2, while ensuring that the stainless steel spring 31 will not affect the normal closing of the lower pressure plate 1 and the upper pressure plate 2.

[0037] In one embodiment, the number of elastic elements 3 is four and they are evenly distributed around the support boss 21, so that the lower pressure plate 1 and the upper pressure plate 2 are subjected to uniform force, and thus the entire piece of glass 4 sandwiched between the two is subjected to uniform force, thereby improving the positioning accuracy of the glass cover plate 41.

[0038] In one embodiment, both the upper pressure plate 2 and the lower pressure plate 1 are made of bakelite. Bakelite is a synthetic thermosetting plastic, polymerized from phenol and formaldehyde under high temperature and pressure, and possesses excellent insulation, heat resistance, and mechanical strength. The use of bakelite for both the upper pressure plate 2 and the lower pressure plate 1 extends the service life of the glass cover plate shattering fixture.

[0039] In one embodiment, the four corners of the limiting groove 11 are provided with avoidance grooves 13 to avoid the four corners of the supporting boss 21, so as to prevent the supporting boss 21 from interfering with the lower pressure plate 1 when the lower pressure plate 1 and the upper pressure plate 2 are closed.

[0040] To facilitate understanding of this application, the following operating instructions for the glass cover plate cleaving fixture are provided. First, a single piece of glass 4 with multiple glass cover plates 41 is provided and placed on the elastic member 3 or on the cleaving boss 22. Then, the lower pressure plate 1 and the upper pressure plate 2 are closed and fixed to clamp the single piece of glass 4. At this time, the slit groove 12 is aligned sequentially with the glass cover plate 41 and the cleaving boss 22, and the protruding structure on the glass cover plate 41 is located within the clearance groove 221. Finally, the single piece of glass 4 is cut using a laser, and the cut-off glass cover plate 41 is removed from the slit groove 12, completing the cleaving process of the glass cover plate 41.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
