Description

Technical Field

[0001] The present application relates to the field of support technology, and in particular to a grinding support device. Background Art

[0002] At present, when ultra-thin glass is produced, the ultra-thin substrate glass needs to be ground. When grinding, the substrate glass needs to be placed on a grinding support platform. When the glass is placed on the grinding support platform for grinding, the distance between the edge of the substrate glass and the outer edge of the grinding support platform must be greater than 20 mm to ensure that the cooling water cover and the grinding table block do not interfere with each other during the grinding process. Because the thickness of the substrate glass is relatively small (≤0.7 mm), and such a large distance (the distance between the edge of the substrate glass and the outer edge of the grinding support platform is greater than 20 mm) causes the cooling water to rush up and down the substrate glass during grinding, and the grinding wheel applies a certain grinding force to the substrate glass during grinding, which will cause the position of the substrate glass on the glass substrate to shift, thereby causing grinding defects in the substrate glass.

[0003] In the prior art, the surface of the grinding support platform is formed by splicing a plurality of blocks. The blocks formed by splicing may move during the grinding process, resulting in poor levelness and stability, and easily causing grinding defects.

[0004] Therefore, how to improve the stability of the grinding support device becomes an urgent problem to be solved. Summary of the invention

[0005] A technical problem to be solved by the present application is: how to provide a grinding support device with high stability.

[0006] In order to solve the above technical problems, the present application provides a grinding support device, comprising:

[0007] The block is integrally formed and has a first surface and a second surface disposed opposite to the first surface, the first surface is a plane and is used to place the glass substrate, and the block has a first through groove that runs through the first surface and the second surface;

[0008] A support frame, the support frame has a bottom surface and a top surface that are arranged opposite to each other, the top surface is connected to the second surface, and the support frame has a second through groove that passes through the bottom surface and the top surface, and one end of the second through groove is connected to the first through groove;

[0009] A vacuum pumping component is connected to the other end of the second through hole.

[0010] In this embodiment, a cross-sectional area of ​​the first through-groove in a direction parallel to the first surface is greater than a maximum cross-sectional area of ​​the second through-groove in a direction parallel to the first surface.

[0011] In this embodiment, the second through groove is extended in a direction perpendicular to the first surface of the block;

[0012] The diameters of the second through grooves along the extension direction are the same; or

[0013] The diameter of the second through groove close to the top surface is larger than the diameter close to the bottom surface.

[0014] In this embodiment, the second through groove is a cylindrical structure, the first through groove is a disc-shaped structure, and the cross-sections of the first through groove and the second through groove along the direction perpendicular to the first surface are T-shaped structures.

[0015] In this embodiment, a plurality of second through slots are arranged at intervals on the support frame, and the plurality of second through slots do not interfere with each other;

[0016] The block is provided with a plurality of first through grooves corresponding to the second through grooves one by one.

[0017] In this embodiment, the support frame also has a plurality of hollow structures.

[0018] In this embodiment, the table block and support frame are aluminum structures.

[0019] In this embodiment, the table block and the support frame are connected via a first fixing assembly.

[0020] In this embodiment, it also includes:

[0021] The base is connected to the bottom surface of the support frame via a second fixing component.

[0022] In this embodiment, the first fixing component is a bolt;

[0023] The second fixing component is a bolt.

[0024] Therefore, the grinding support device provided by the present application includes a table block, a support frame and a vacuum assembly. The table block is an integral structure formed in one piece. The first surface of the table block is used to place a glass substrate. The low-frequency surface is a plane, and the table block is an integral structure. Therefore, during the grinding process, the levelness of the first surface of the table block will not change, and the levelness of the first surface will not be inconsistent due to the vibration generated during the grinding process, thereby ensuring the grinding quality. The table block is provided with a first through hole that passes through the first surface and the second surface. The second surface of the table block is connected to a support frame, and the support frame is used to support and fix the table block so that the table block can be used to place a glass substrate. The support frame is provided with a second through groove that passes through the top surface and the bottom surface. The first through groove is connected to the second through groove, and the end of the second through groove away from the first through groove is also connected to a vacuum assembly. Therefore, when the glass substrate is placed on the first surface of the block, the vacuum assembly can absorb the air between the glass substrate and the first surface through the second through groove and the first through groove, so that the glass substrate can be adsorbed on the first surface of the block, thereby avoiding the problem of the glass substrate shifting during the grinding process due to weak adsorption, improving the accuracy of the block, increasing the stability of the grinding support device, and thus avoiding grinding defects of the product and improving product quality.

[0035] In the related art, when producing ultra-thin glass, it is necessary to grind the ultra-thin substrate glass, but the surface of the grinding support platform currently used to place the glass substrate is formed by splicing a plurality of blocks. The blocks formed by splicing will move during the grinding process, resulting in poor levelness and stability, and easy to cause grinding defects. The present application provides a grinding support device, which uses an integrally formed block structure, so that during the grinding process, the block will not have levelness and stability problems due to the vibration caused by grinding, thereby avoiding the generation of grinding defects, and through the first through groove and the second through groove set on the block and the support frame connected to the vacuum assembly, the glass substrate placed on the block can be adsorbed and fixed, further avoiding the movement of the glass substrate during grinding, and further improving the grinding quality.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] like Figure 1 As shown, the present application provides a grinding support device 1, comprising:

[0038] The block 11 is integrally formed and has a first surface 111 and a second surface 112 disposed opposite to the first surface 111. The first surface 111 is a plane for placing a glass substrate. The block 11 has a first through groove 113 that passes through the first surface 111 and the second surface 112.

[0039] The support frame 12 has a bottom surface and a top surface that are oppositely arranged, the top surface is connected to the second surface 112, and the support frame has a second through groove 121 that penetrates the bottom surface and the top surface, and one end of the second through groove 121 is connected to the first through groove 113;

[0040] A vacuum pumping component is connected to the other end of the second through hole.

[0041] In this embodiment, the block 11 is a plate-like structure, and the first surface 111 can be circular or rectangular, which can be set according to the needs. The support frame 12 is set under the block 11 to support the block 11. It can be a regular structure or a scissor-shaped structure to better provide support for the block 11. The vacuum pump component can be a vacuum pump, which is used to absorb the air between the glass substrate and the block 11 through the second through groove 121 and the first through groove 113, so that the glass substrate can be vacuum-adsorbed on the block 11 to achieve the fixation of the glass substrate.

[0042] The present application provides a grinding support device 1, comprising a table block 11, a support frame 12 and a vacuum assembly. The table block 11 is an integral structure formed in one piece. The first surface 111 of the table block 11 is used to place a glass substrate. The bass surface is a plane, and the table block 11 is an integral structure. Therefore, during the grinding process, the levelness of the first surface 111 of the table block 11 will not change, and the levelness of the first surface 111 will not be inconsistent due to the vibration generated during the grinding process, thereby ensuring the grinding quality. The table block 11 is provided with a first through hole that passes through the first surface 111 and the second surface 112. The second surface 112 of the table block 11 is connected to the support frame 12. The support frame 12 is used to support and fix the table block 11 so that the table block 11 can be used to place a glass substrate. The support frame 12 is provided with a second through groove 121 that passes through the top surface and the bottom surface. The first through groove 113 is connected to the second through groove 121, and the end of the second through groove 121 away from the first through groove 113 is also connected to the vacuum assembly. Therefore, when the glass substrate is placed on the first surface 111 of the block 11, the vacuum assembly can absorb the air between the glass substrate and the first surface 111 through the second through groove 121 and the first through groove 113, so that the glass substrate can be adsorbed on the first surface 111 of the block 11, thereby avoiding the problem of the glass substrate shifting during the grinding process due to weak adsorption, improving the accuracy of the block 11, increasing the stability of the grinding support device 1, and thus avoiding grinding defects of the product, improving the grinding yield, improving product quality and the accuracy of the device, and also extending the life of the device.

[0043] In the embodiment of the present application, a cross-sectional area of ​​the first through-groove 113 in a direction parallel to the first surface 111 is greater than a maximum cross-sectional area of ​​the second through-groove 121 in a direction parallel to the first surface 111 .

[0044] In this embodiment, the first through groove 113 can be extended in a direction perpendicular to the first surface 111 of the block 11, so that the length of the first through groove 113 is the shortest, thereby accelerating the vacuuming speed. The second through groove 121 can be extended in a direction perpendicular to the first surface 111 of the block 11, or can be extended according to the setting of the support frame 12, as long as the two ends of the second through groove 121 are respectively located at the bottom surface and the top surface.

[0045] In this embodiment, the cross-sectional area of ​​the first through groove 113 in the direction parallel to the first surface 111 is larger than the maximum cross-sectional area of ​​the second through groove 121 in the direction parallel to the first surface 111, so that the first through groove 113 can be connected with the area to be vacuumed through a larger area, thereby increasing the vacuuming speed. The area to be vacuumed is the area between the block 11 and the glass substrate.

[0046] like Figure 1As shown, in the embodiment of the present application, the second through groove 121 is extended in a direction perpendicular to the first surface 111 of the block 11;

[0047] The diameters of the second through grooves 121 along the extending direction are the same; or

[0048] The diameter of the second through groove 121 close to the top surface is larger than the diameter close to the bottom surface.

[0049] In this embodiment, when the support frame 12 has a setting space, the second through groove 121 can be extended in a direction perpendicular to the first surface 111 of the block 11, that is, extended in a vertical direction. At this time, the length of the second through groove 121 is the shortest, so the vacuuming speed is the fastest, and vacuuming can be achieved quickly to adsorb the glass substrate on the block 11.

[0050] In this embodiment, the second through groove 121 has the same diameter along the extension direction, so that the second through groove 121 is a cylindrical structure or a regular quadrangular prism structure, and the air circulation speed of the second through groove 121 is the same along the extension direction, so that the air circulation speed in the second through groove 121 is uniform.

[0051] In this embodiment, the diameter of the second through groove 121 along the extension direction gradually decreases from bottom surface to bottom surface, so that the second through groove 121 is a truncated cone structure, and the air circulation speed of the second through groove 121 along the extension direction gradually decreases from the top surface to the bottom surface, so that the air in the area to be vacuumed can be quickly absorbed and then slowly transmitted to speed up the speed at which the glass substrate is adsorbed on the block 11.

[0052] In the embodiment of the present application, the second through groove 121 is a cylindrical structure, the first through groove 113 is a disc-shaped structure, and the cross-section of the first through groove 113 and the second through groove 121 along the direction perpendicular to the first surface 111 is a T-shaped structure.

[0053] In this embodiment, the cross-section of the groove body formed by the first through groove 113 and the second through groove 121 as a whole is a T-shaped structure, the diameter of the first through groove 113 of the disc-shaped structure is greater than the diameter of the cylindrical structure, and the cross-sectional area of ​​the first through groove 113 of the disc-shaped structure is greater than the second through groove 121 of the cylindrical structure, so that the air in the area to be vacuumed can be quickly absorbed, and the glass substrate can be quickly absorbed and fixed on the block 11.

[0054] like Figure 1 As shown, in the embodiment of the present application, a plurality of second through slots 121 are arranged at intervals on the support frame 12, and the plurality of second through slots 121 do not interfere with each other;

[0055] The block 11 is provided with a plurality of first through grooves 113 corresponding to the second through grooves 121 one by one.

[0056] In this embodiment, the plurality of second through grooves 121 provided on the support frame 12 are evenly distributed on the support frame 12, and correspondingly, the plurality of first through grooves 113 are also evenly distributed on the block 11, so that the glass substrate can be more firmly and evenly absorbed and fixed, thereby avoiding displacement of the glass substrate, deformation or up and down vibration of the glass substrate, and further avoiding grinding defects of the glass substrate, thereby avoiding product waste or quality risks.

[0057] like Figure 1 As shown, in the embodiment of the present application, the support frame 12 also has a plurality of hollow structures 122 .

[0058] In this embodiment, the weight of the grinding support device 1 can be reduced, thereby reducing the load rate of the entire device, extending its service life, reducing the failure rate of the equipment, enhancing the equipment accuracy, and improving the processing quality of the product.

[0059] In the embodiment of the present application, the platform block 11 and the support frame 12 are aluminum structures.

[0060] In this embodiment, the aluminum material is lighter in weight, thereby reducing the weight of the grinding support device 1, thereby reducing the load rate of the entire device, extending its service life, reducing the failure rate of the equipment, enhancing the equipment accuracy, and improving the processing quality of the product.

[0061] In the embodiment of the present application, the platform block 11 and the support frame 12 are connected via a first fixing component.

[0062] In this embodiment, the table block 11 and the support frame 12 can be fixedly connected or detachably connected. The table block 11 and the support frame 12 can be connected by welding or by a first fixing component. As long as the table block 11 and the support frame 12 can be fixedly connected, no limitation is made here.

[0063] In the embodiment of the present application, it also includes:

[0064] The base 13 is connected to the bottom surface of the support frame 12 via a second fixing component.

[0065] In this embodiment, a side of the support frame 12 away from the platform 11 is further connected to a base 13, and the base 13 is used to support the support frame 12. The base 13 can be made of stainless steel to prevent it from tipping over due to being too light. It can also be made of aluminum like the platform 11 and the support frame 12 to reduce weight.

[0066] In the embodiment of the present application, the first fixing component is a bolt;

[0067] The second fixing component is a bolt.

[0068] In this embodiment, the table block 11 is connected to the support frame 12 via a first fixing component, which may be a bolt, an adhesive layer, or other fixing structures. The support frame 12 is connected to the base 13 via a second fixing component, which may be a bolt, an adhesive layer, or other fixing structures.

[0069] In the embodiment of the present application, a grinding wheel and a water cover are also included. The grinding wheel is arranged on the edge of one side of the block 11 through an external structure and is located above the block 11, so that the portion of the glass substrate extending out of the block 11 can be ground to achieve grinding of the glass substrate. The water cover is arranged outside the grinding wheel and can spray water during the grinding process to avoid excessive temperature during the grinding process.
