Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a glass grinding device for liquid crystal display substrates. Background Technology

[0002] The production of LCD glass substrates is a highly precise and technology-intensive process that requires extremely high cleanliness, flatness, purity, and dimensional stability. After the glass substrate is completely cured and cooled to a certain temperature, the continuous glass strip is conveyed to the cutting area and cut into specified sizes. The cut glass edges are usually quite sharp and prone to micro-cracks or chipping. Therefore, it is necessary to use a grinding device to chamfer and grind the four sides of the glass to form a smooth bevel or arc, which is called glass edge grinding.

[0003] Existing LCD substrate glass polishing devices mainly use diamond grinding wheels to polish the edges and corners of the glass. The grinding wheel consists of a wheel body and abrasive. The abrasive is usually fixed to the wheel body using processes such as sintering, bonding, and electroplating. Because it is a fixed structure, when the abrasive is severely worn and can no longer be used, it is usually replaced along with the wheel body. The wheel body is usually made of materials such as aluminum alloy, which occupies most of the area of ​​the abrasive, resulting in high cost. Moreover, the wheel body does not participate in the polishing work, so its surface wear is less, and its service life will far exceed that of the abrasive. Replacing the wheel body along with the abrasive would be wasteful. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a glass polishing device for liquid crystal display substrates to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass polishing device for a liquid crystal display substrate, comprising a device body and a motor, characterized in that: a first wheel is connected to the output end of the motor, and a second wheel is connected to the top of the first wheel; positioning rods and positioning holes are provided on both sides of the bottom of the second wheel and both sides of the top of the first wheel; a support ring is connected between the first wheel and the second wheel, and an abrasive is fixed to the outer ring of the support ring; positioning teeth are fixed to the inner ring of the abrasive; positioning grooves are provided on the outer rings of both the first wheel and the second wheel; a limit bolt is connected between the first wheel, the second wheel, and the positioning teeth, and an anti-loosening washer is sleeved on the outside of the limit bolt.

[0006] By adopting the above technical solution, during replacement, the workers disassemble the limiting bolts and anti-loosening washers sequentially. Then, the workers can remove the second wheel from the top of the first wheel. Removing the second wheel ends the limiting of the support ring, allowing the workers to remove the support ring and abrasive together for replacement. During installation, the workers place the new support ring containing the new abrasive onto the outer ring of the first wheel. Then, the workers install the second wheel back onto the top of the first wheel, using the limiting bolts and anti-loosening washers to limit the first and second wheels. The positioning rod and positioning hole work together to ensure concentricity and torsional strength between the first and second wheels, strengthening the connection, reducing radial force on the limiting bolts, and extending the service life of the limiting bolts. Furthermore, the positioning teeth and positioning groove work together to ensure concentricity and torsional strength between the first and second wheels and the support ring, strengthening the connection, reducing radial force on the limiting bolts, and increasing the torsional strength between the first and second wheels. The overall connection strength is improved, so the limiting bolts only need to resist axial force, resulting in good connection stability and high strength.

[0007] Furthermore, the first wheel body has a mounting hole at its bottom, and a limit mechanism is provided between the motor output end and the mounting hole, and the first wheel body is detachably connected to the limit mechanism through the mounting hole.

[0008] By adopting the above technical solution, when it is necessary to replace the entire grinding wheel, it is only necessary to operate the limiting mechanism to end the limiting between the first wheel body and the limiting mechanism, so that the entire grinding wheel can be removed.

[0009] Furthermore, the second wheel body is detachably connected to the first wheel body via a limiting bolt, and the support ring is detachably connected to both the first and second wheel bodies.

[0010] By adopting the above technical solution, when the abrasive is worn out and can no longer be used, the limiting bolt, the anti-loosening washer, and the second wheel can be disassembled in sequence to end the limiting of the support ring. Then the support ring and the abrasive can be disassembled and replaced together. Compared with replacing the entire grinding wheel, less material is used, reducing replacement costs.

[0011] Furthermore, the longitudinal section of the support ring is C-shaped.

[0012] By adopting the above technical solution, the shape of the support ring can increase the contact area between the support ring and the abrasive, thereby increasing the bonding area and making the abrasive bonding stability better.

[0013] Furthermore, there are eight positioning rods and eight positioning holes, arranged in groups of four, with one group of positioning rods and holes interspersed with another group of positioning rods and holes.

[0014] By adopting the above technical solution, the concentricity and torsional strength between the first wheel body and the second wheel body are ensured through the cooperation of the positioning rod and the positioning hole, the connection effect is strengthened, the radial force on the limit bolt is reduced, and the service life of the limit bolt is extended.

[0015] Furthermore, multiple positioning teeth and positioning grooves are provided, and the multiple positioning teeth and positioning grooves are distributed in a ring array.

[0016] By adopting the above technical solution, the positioning teeth and positioning grooves cooperate to ensure the concentricity and torsional strength between the first wheel body, the second wheel body and the support ring, strengthen the connection effect, reduce the radial force on the limit bolt, and improve the torsional strength between the first wheel body and the second wheel body. The overall connection strength is improved, so that the limit bolt only needs to resist the axial force, resulting in good connection stability and high strength.

[0017] Furthermore, a pushing mechanism and a conveying mechanism are respectively installed on the top of the main body of the device, and an adjustment mechanism is installed inside the main body of the device, with the motor installed on the side of the adjustment mechanism.

[0018] By adopting the above technical solution, the glass substrate is transported to the conveying mechanism by conveying equipment such as roller conveyors or by manual placement. During this process, the pushing mechanism pushes the glass substrate to calibrate its position, preventing it from shifting and colliding with the main body of the device during subsequent displacement. Then, the glass substrate is sent into the main body of the device by the conveying mechanism. During this process, the horizontal position and vertical height of the motor are adjusted by the adjusting mechanism so that the abrasive can correspond to the glass substrate. Then, the motor output drives the first wheel, the second wheel, the support ring, the abrasive and other structures to rotate, so that the abrasive moves relative to the edge of the glass substrate to start the grinding work. After grinding, the glass substrate is transported to the rear of the main body of the device and unloaded by conveying equipment such as roller conveyors or by manual removal.

[0019] Furthermore, the first wheel, the second wheel, and the positioning rod are made of 6063 or 6061-T6 aluminum alloy.

[0020] By adopting the above technical solutions, the cost of 6063 aluminum alloy is lower than that of 6061-T6 aluminum alloy, which can save on usage costs and is suitable for medium and low cost, lightweight and corrosion resistance requirements. Although 6061-T6 has a higher cost, it has higher strength and can withstand the centrifugal force generated by higher speed, making it suitable for high load and high speed requirements.

[0021] Furthermore, both the support ring and the positioning teeth are made of galvanized 45 steel.

[0022] By adopting the above technical solution, the support ring is made of galvanized 45 steel, which gives the support ring good corrosion resistance, wear resistance and impact resistance, and reduces the residual magnetism during magnetic separation. During the recycling process, the recycling company can separate the crushed support ring from the crushed abrasive through magnetic separation, and thus recycle them separately.

[0023] Furthermore, the top of the second wheel body is provided with a clearance hole, and the diameter of the clearance hole is larger than the diameter of the mounting hole.

[0024] By adopting the above technical solution, the setting of the clearance hole ensures that the limiting mechanism is only connected to the first wheel body, and the second wheel body will not obstruct the limiting mechanism. Firstly, when changing the abrasive, it is not necessary to remove the first wheel body from the limiting mechanism, simplifying the disassembly process. Secondly, when it is necessary to replace the entire grinding wheel, only the limiting mechanism needs to be operated, and the limiting bolts do not need to be operated.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the arrangement of a first wheel body, a second wheel body, a support ring, abrasive, limiting bolts, and anti-loosening washers, allows for the sequential disassembly of the limiting bolts, anti-loosening washers, and second wheel body when the abrasive is severely worn and can no longer be used. This releases the limiting effect on the support ring, allowing it to be disassembled and replaced along with the abrasive. Compared to replacing the entire grinding wheel, this method uses less material, reducing replacement costs. Furthermore, the support ring can be separated by magnetic separation during recycling, improving recycling efficiency.

[0027] 2. This utility model, through the setting of positioning rod and positioning hole, ensures the concentricity and torsional strength between the first wheel body and the second wheel body, strengthens the connection effect, reduces the radial force on the limit bolt, and extends the service life of the limit bolt by cooperating with the positioning rod and positioning hole.

[0028] 3. By setting positioning teeth and positioning grooves, and with the positioning teeth and positioning grooves cooperating, this utility model ensures the concentricity and torsional strength between the first wheel body and the second wheel body and the support ring, strengthens the connection effect, reduces the radial force on the limit bolt, and can improve the torsional strength between the first wheel body and the second wheel body. The overall connection strength is improved, so that the limit bolt only needs to resist the axial force, resulting in good connection stability and high strength. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A glass polishing apparatus for liquid crystal display substrates, such as Figures 1-6As shown, the device includes a main body 1 and a motor 5. The output end of the motor 5 is connected to a first wheel 6, and the top of the first wheel 6 is connected to a second wheel 7. Positioning rods 15 and positioning holes 16 are provided on both sides of the bottom of the second wheel 7 and on both sides of the top of the first wheel 6. There are eight positioning rods 15 and eight positioning holes 16, arranged in groups of four. One group of positioning rods 15 and positioning holes 16 is staggered with another group of positioning rods 15 and positioning holes 16. A support ring 11 is connected between the first wheel 6 and the second wheel 7. The longitudinal section of the support ring 11 is C-shaped. An abrasive 12 is fixed on the outer ring of the support ring 11. Positioning teeth 17 are fixed on the inner ring of the abrasive 12. Both the first wheel body 6 and the positioning teeth 17 are made of galvanized 45 steel. Positioning grooves 18 are provided on the outer rings of both the first wheel body 6 and the second wheel body 7. Multiple positioning teeth 17 and positioning grooves 18 are provided, arranged in a circular array. Limiting bolts 13 connect the first wheel body 6, the second wheel body 7, and the positioning teeth 17. Anti-loosening washers 14 are fitted onto the outside of the limiting bolts 13. The second wheel body 7 is detachably connected to the first wheel body 6 via the limiting bolts 13. The support ring 11 is detachably connected to the first wheel body 6 and the second wheel body 7. The difference between this grinding wheel and existing grinding wheels lies in the fact that existing grinding wheels are integrally formed from a single body. Then, it is fixed to the abrasive 12 through sintering, bonding, etc. When the abrasive 12 is severely worn, the entire wheel body needs to be replaced together, resulting in material waste and recycling trouble. However, this technical solution only optimizes the traditional fixing of the abrasive 12 to the wheel body to fixing the abrasive 12 to the support ring 11, with the first wheel body 6, the second wheel body 7, and the support ring 11 being detachable structures. The production process of the abrasive 12 can be set according to the conventional settings in the field, such as using a ceramic adhesive to bond and fix the abrasive 12 to the support ring 11, and the abrasive 12 being diamond abrasive 12, etc. First, only the support ring 11 is recycled, while other components such as the first wheel body 6 and the second wheel body 7 are retained. This design minimizes waste during disassembly and recycling, and reduces costs when purchasing new abrasive 12 due to the small size of the support ring 11 and the reduced material consumption. Secondly, the support ring 11 is made of galvanized 45 steel, giving it excellent corrosion resistance, wear resistance, and impact resistance, while also reducing the residual magnetism during magnetic separation. During recycling, the recycling company can separate the pulverized support ring 11 from the pulverized abrasive 12 using magnetic separation, allowing for separate recycling. In conventional designs, the wheel body is typically made of non-magnetic materials such as aluminum alloy or engineering plastics, making the separation of the abrasive 12 from the wheel body cumbersome. Therefore, this technical solution reduces the difficulty of separation during recycling.

[0040] See Figures 1-6In the above embodiment, a pushing mechanism 2 and a conveying mechanism 3 are respectively installed on the top of the main body 1. An adjusting mechanism 4 is installed inside the main body 1. A motor 5 is installed on the side of the adjusting mechanism 4. The glass substrate is conveyed to the conveying mechanism 3 by conveying equipment such as a roller conveyor or by manual placement. During this process, the pushing mechanism 2 pushes the glass substrate to calibrate its position, preventing the glass substrate from shifting and colliding with the main body 1 during subsequent displacement. Then, the glass substrate is sent into the main body 1 by the conveying mechanism 3. During this process, the horizontal position and vertical height of the motor 5 are adjusted by the adjusting mechanism 4 so that the abrasive 12 can correspond to the glass substrate. Then, the output end of the motor 5 drives the first wheel 6, the second wheel 7, and the support. The rotating structure of the support ring 11, abrasive 12, etc. causes the abrasive 12 to move relative to the edge of the glass substrate to start the grinding work. After grinding, the glass substrate is transported to the rear of the main body 1 of the device and unloaded by conveying equipment such as roller conveyor or manual material handling. The bottom of the first wheel body 6 is provided with a mounting hole 8. A limit mechanism 9 is provided between the output end of the motor 5 and the mounting hole 8. The limit mechanism 9 includes a screw, a lock nut (pressure plate), and a positioning pin (lock pin) to prevent the first wheel body from rotating relative to the other. The first wheel body 6 is detachably connected to the limit mechanism 9 through the mounting hole 8. When the entire grinding wheel needs to be replaced, the limit mechanism 9 can be operated to release the limit between the first wheel body 6 and the limit mechanism 9, so that the entire grinding wheel can be removed.

[0041] Example 2:

[0042] Based on the above embodiment one, in order to simplify the disassembly and assembly steps in some cases, the following settings are now adopted.

[0043] See Figures 1-6 In the above embodiment, the top of the second wheel body 7 is provided with a clearance hole 10. The diameter of the clearance hole 10 is larger than the diameter of the mounting hole 8. The clearance hole 10 ensures that the limiting mechanism 9 is only connected to the first wheel body 6, and the second wheel body 7 will not obstruct the limiting mechanism 9. Firstly, when changing the abrasive 12, it is not necessary to remove the first wheel body 6 from the limiting mechanism 9, which simplifies the disassembly process. Secondly, when the entire grinding wheel needs to be replaced, only the limiting mechanism 9 needs to be operated, and the limiting bolt 13 does not need to be operated.

[0044] Example 3:

[0045] Based on the above embodiment one, the following settings are now adopted to be applicable to different scenarios.

[0046] See Figures 1-6In the above embodiments, the first wheel body 6, the second wheel body 7, and the positioning rod 15 are made of 6063 or 6061-T6 aluminum alloy. The cost of 6063 aluminum alloy is lower than that of 6061-T6 aluminum alloy, which can save on usage costs and is suitable for medium and low cost, lightweight and corrosion resistance requirements. Although 6061-T6 is more expensive, it has higher strength and can withstand the centrifugal force generated by higher speed, making it suitable for high load and high speed requirements.

[0047] The implementation principle of this utility model is as follows: First, the glass substrate is transported to the conveying mechanism 3 by a conveying device such as a roller conveyor or by manual placement. During this process, the pushing mechanism 2 pushes the glass substrate to calibrate its position, preventing it from shifting and colliding with the main body 1 of the device during subsequent displacement. Then, the glass substrate is fed into the main body 1 of the device by the conveying mechanism 3. During this process, the horizontal position and vertical height of the motor 5 are adjusted by the adjusting mechanism 4 so that the abrasive 12 can correspond to the glass substrate. Then, the output end of the motor 5 drives the first wheel 6, the second wheel 7, the support ring 11, the abrasive 12, and other structures to rotate, so that the abrasive 12 moves relative to the edge of the glass substrate to start the grinding work. After grinding, the glass substrate is transported to the rear of the main body 1 and unloaded by a conveying device such as a roller conveyor or by manual removal. It should be noted that the glass grinding device for liquid crystal display substrates is the glass edge grinding machine in the prior art, which is a well-known technology in this field. Therefore, its working principle is only briefly described in this technical solution.

[0048] When the abrasive 12 is severely worn and needs to be replaced, the setting of the clearance hole 10 ensures that the limiting mechanism 9 is only connected to the first wheel body 6, and the second wheel body 7 will not obstruct the limiting mechanism 9. Firstly, when replacing the abrasive 12, it is not necessary to remove the first wheel body 6 from the limiting mechanism 9, simplifying the disassembly process. Secondly, when the entire grinding wheel needs to be replaced, only the limiting mechanism 9 needs to be operated, without the need to operate the limiting bolt 13. In this technical solution, the grinding wheel refers to a multi-component mechanism composed of the first wheel body 6, the second wheel body 7, the mounting hole 8, the clearance hole 10, the support ring 11, the abrasive 12, the limiting bolt 13, the anti-loosening washer 14, the positioning rod 15, the positioning hole 16, the positioning tooth 17, and the positioning groove 18.

[0049] During replacement, the worker removes the limiting bolt 13 and the anti-loosening washer 14 in sequence. Then, the worker can remove the second wheel body 7 from the top of the first wheel body 6. Removing the second wheel body 7 ends the limiting of the support ring 11. The worker can then remove the support ring 11 and the abrasive 12 together for replacement. During installation, the worker places the new support ring 11 containing the new abrasive 12 onto the outer ring of the first wheel body 6. Then, the worker installs the second wheel body 7 back onto the top of the first wheel body 6, and uses the limiting bolt 13 and the anti-loosening washer 14 to limit the first wheel body 6 and the second wheel 7. The positioning rod... The positioning teeth 15 and 16 cooperate to ensure the concentricity and torsional strength between the first wheel body 6 and the second wheel body 7, enhance the connection effect, reduce the radial force on the limit bolt 13, and extend the service life of the limit bolt 13. The positioning teeth 17 and 18 cooperate to ensure the concentricity and torsional strength between the first wheel body 6 and the second wheel body 7 and the support ring 11, enhance the connection effect, reduce the radial force on the limit bolt 13, and improve the torsional strength between the first wheel body 6 and the second wheel body 7. The overall connection strength is improved, so that the limit bolt 13 only needs to resist the axial force, resulting in good connection stability and high strength.

[0050] The difference between this technical solution and existing grinding wheels lies in the fact that existing grinding wheels are integrally molded and then fixed to the abrasive 12 through sintering, bonding, etc. When the abrasive 12 wears out severely, the entire wheel body needs to be replaced, resulting in material waste and recycling difficulties. This technical solution, however, optimizes the traditional fixing of the abrasive 12 to the wheel body to fixing the abrasive 12 to the support ring 11, with the first wheel body 6, the second wheel body 7, and the support ring 11 being detachable structures. The manufacturing process of the abrasive 12 can be set according to conventional practices in the field, such as using ceramic adhesives to bond the abrasive 12 to the support ring 11, or using metal brazing to fix the abrasive, etc. The abrasive 12 is diamond abrasive 12, etc. Firstly, only the support ring 11 is recycled. The first wheel body 6 and the second wheel body 7, along with other components, are retained, thus minimizing waste during disassembly and recycling. Furthermore, the small size of the support ring 11 reduces material consumption when purchasing new abrasive 12, resulting in lower costs. Secondly, the support ring 11 is made of galvanized 45 steel, giving it excellent corrosion resistance, wear resistance, and impact resistance, while also reducing the residual magnetism during magnetic separation. This allows recycling companies to separate the pulverized support ring 11 from the pulverized abrasive 12 using magnetic separation, enabling separate recycling. In contrast, conventional designs in this field typically use non-magnetic materials such as aluminum alloys and engineering plastics, making the separation of the abrasive 12 from the wheel body cumbersome. Therefore, this technical solution reduces the difficulty of separation during recycling.
