Description

Technical Field

[0001] This invention belongs to the field of glass grinding technology, specifically a glass grinding device. Background Technology

[0002] The liquid crystal glass substrate is an important component of the liquid crystal display screen. Grinding is an important process in the processing of the liquid crystal glass substrate. In the grinding process, the liquid crystal glass substrate needs to be adsorbed on the adsorption device of the grinding machine, and then the four corners of the glass substrate are ground by the grinding wheel of the grinding machine.

[0003] Existing technologies also offer some solutions. For example, patent application CN219485391U discloses a grinding wheel for glass grinding, comprising: a grinding wheel body, the grinding wheel body being a flat cylindrical shape, a mounting hole being provided at the center of the grinding wheel body, and multiple chip removal grooves being provided on the grinding wheel body. The chip removal grooves are parallel to the axial direction of the grinding wheel body, and both ends of the chip removal grooves extend to the two end faces of the grinding wheel body, respectively. The openings of the chip removal grooves extend to the circumferential surface of the grinding wheel body, and the multiple chip removal grooves are arranged in a circular array around the center of the grinding wheel body. The circumferential surface of the grinding wheel body is the chip removal surface. The chips generated during high-speed grinding can be discharged promptly and effectively, improving grinding efficiency.

[0004] While the above technical solution solves the problem of timely removal of debris, other issues still exist in practical use. For example, when grinding glass, coolant is needed to cool the grinding head and glass panel. However, the coolant is highly viscous due to the presence of glass debris, which often causes blockage in the coolant recovery pipe. Furthermore, when the glass is placed inside the placement cavity, its close contact with the cavity wall affects subsequent removal.

[0005] Therefore, the present invention provides a glass grinding apparatus. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The glass grinding device of the present invention includes a grinding worktable, a support base fixedly installed below the grinding worktable, a plurality of receiving platforms fixedly installed on the front end face of the support base, the plurality of receiving platforms being arranged in a linear array on the front end face of the support base, and a placement groove being formed on the upper end face of each receiving platform for placing glass to be ground. A grinding seat is installed on the front end face of the support base, the grinding seat being integrally formed by a drive seat and a grinding head, the grinding seat facing the glass inside the placement groove. A coolant pipe is installed on the front end face of the support base, the end of the coolant pipe being connected to an external storage seat. An agitation mechanism is provided on the front end face of the support base and below the receiving platforms, the agitation mechanism being used to agitate and recover the coolant. A discharge mechanism is provided inside the receiving platforms, the discharge mechanism being used to automatically lift out the ground glass.

[0008] Preferably, a pressure relief valve is fixedly installed on the front end face of the support base, and the pressure relief valve is connected to the grinding head side inside the grinding base through a pressure relief pipe. Two liquid permeation tanks are opened inside the receiving platform.

[0009] Preferably, the agitation mechanism includes two recovery pipes fixedly installed on the front end face of the support base. The top ends of the two recovery pipes extend into the liquid permeation tank. A collection tank is provided below the receiving platform. A return pipe is provided at the bottom of the collection tank. The end of the return pipe away from the collection tank is connected to the end of the coolant pipe. The outside of the return pipe is connected to an external control pump body through a power line.

[0010] Preferably, the agitation mechanism further includes a rotating vertical shaft rotatably disposed inside the collection tank, with stirring blades fixedly installed on the outer circumferential surface of the rotating vertical shaft. The rotating vertical shaft is made of magnetic material, and a magnetic stirrer is disposed below the receiving platform. A waste pipe is threadedly installed at the bottom of the collection tank, with the top end of the waste pipe contacting the end of the return pipe. A filter screen is disposed inside the return pipe near the waste pipe.

[0011] Preferably, the discharge mechanism includes a placement plate that is slidably mounted on the side wall of the placement groove. The shape of the placement plate is adapted to the shape of the glass to be ground. The receiving platform is provided with a fixing unit inside, which is used to fix the glass to be ground.

[0012] Preferably, the fixing unit includes a sliding groove formed inside the receiving platform. Two sliding grooves are provided and are symmetrically arranged with respect to the receiving platform. An electric push rod is fixedly installed inside each sliding groove. A clamping soft sleeve is fixedly installed at the telescopic end of the electric push rod. A rubber sleeve is fitted on the outer surface of the clamping soft sleeve.

[0013] Preferably, the discharge mechanism further includes a through groove inside the receiving platform, in which multiple L-shaped pushers are slidably installed. The side of each L-shaped pusher away from the through groove is connected to the telescopic end of two electric push rods. The groove wall of the placement groove has a vertical groove. Both sides of the placement plate are slidably installed inside the vertical groove via rectangular blocks. Each rectangular block has a wedge block fixedly installed on both sides. Each rectangular block has a limit spring fixedly installed on its lower end face. The end of the limit spring away from the rectangular block is fixedly installed inside the vertical groove. The placement plate is fixedly installed between two rectangular blocks.

[0014] Preferably, a rotating bead is rotatably installed on the side of the L-shaped pusher near the rectangular block, and the rotating bead contacts the side wall of the wedge block; during operation, the rotating bead facilitates the L-shaped pusher to squeeze the wedge block when in contact with it, thereby facilitating the downward movement of the shelf and its complete placement inside the placement groove.

[0015] Preferably, the sidewall of the rectangular block is slidably installed inside the vertical groove via a limiting post, and the vertical groove has a groove adapted to the limiting post; during operation, the limiting post ensures that the rectangular block moves along an axis, which facilitates subsequent glass polishing.

[0016] Preferably, the outer side of the return pipe is connected to an external control pump via a power cord, and a sealing sleeve is provided at the contact point between the return pipe and the coolant pipe; during operation, the clean coolant inside the return pipe can be easily introduced into the coolant pipe through the external pump.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The glass grinding device of the present invention uses stirring blades to agitate the coolant containing glass fragments in the collection tank, so that the glass fragments can quickly pass through the collection tank and filter screen into the return pipe, avoiding the problem of the collection tank being blocked due to the high viscosity of the coolant containing glass fragments. Moreover, some glass fragments with a weight greater than the buoyancy of the coolant will slide into the waste pipe along the collection tank under the obstruction of the filter screen and be stored in the waste pipe. Then, the cleaner coolant will re-enter the coolant pipe along the return pipe, which facilitates the reuse of the coolant.

[0019] 2. The glass grinding device of the present invention moves an L-shaped pusher toward the side close to the wedge block. Then, the end of the L-shaped pusher will press the inclined surface of the wedge block, causing the wedge block to move the rectangular block and the placement plate downward. The rectangular block presses down the limiting spring. After the clamping soft sleeve is fixed to the side wall of the glass, the placement plate is also completely moved into the placement groove. This ensures that most of the coolant and glass fragments fall into the placement groove, ensuring the cleanliness of the entire grinding workbench.

[0020] 3. The glass grinding device of the present invention controls an electric push rod to move the clamping sleeve away from the glass sidewall, and the electric push rod will move the L-shaped pusher away from the wedge block. After the L-shaped pusher is completely separated from the wedge block, the limit spring under pressure returns to its original state and moves the placement plate away from the placement groove. This can avoid the glass from being too close to the groove wall, which would make it difficult to remove the glass later. The operation is more convenient. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 4 As shown, a glass grinding apparatus according to an embodiment of the present invention includes a grinding worktable 1, a support base 2 fixedly installed below the grinding worktable 1, a plurality of receiving platforms 3 fixedly installed on the front end face of the support base 2, the plurality of receiving platforms 3 being arranged in a linear array on the front end face of the support base 2, and a placement groove 4 being provided on the upper end face of each receiving platform 3 for placing the glass to be ground, a grinding seat 5 being installed on the front end face of the support base 2, the grinding seat 5 being integrally formed by a drive seat and a grinding head, the grinding seat 5 facing the glass inside the placement groove 4, a coolant pipe 201 being installed on the front end face of the support base 2, the end of the coolant pipe 201 being connected to an external storage seat, an agitation mechanism being provided on the front end face of the support base 2 and below the receiving platform 3, the agitation mechanism being used to agitate and recover the coolant, and a discharge mechanism being provided inside the receiving platform 3, the discharge mechanism being used to automatically lift out the ground glass;

[0035] During operation, the glass to be ground is placed inside the placement groove 4 of the receiving platform 3. Then, the grinding head is moved closer to the glass by the drive seat inside the grinding seat 5, and the grinding head is controlled to grind the end face of the glass. The grinding method and driving method of the grinding seat 5 are existing technologies and will not be described in detail here. During the glass grinding process, the coolant is flowed from the coolant pipe 201 by the control of the external pump and flows to the grinding position on the end face of the glass. Then, the stirring mechanism can stir the glass fragments and coolant after use and speed up their recovery. Moreover, the discharge mechanism can automatically remove the ground glass to avoid the glass from sticking too much to the wall of the placement groove 4, which would make it difficult to remove the glass.

[0036] A pressure relief valve 6 is fixedly installed on the front end face of the support base 2. The pressure relief valve 6 is connected to the grinding head side inside the grinding base 5 through a pressure relief pipe. Two liquid permeation tanks 301 are opened inside the receiving platform 3.

[0037] During operation, if the pressure of the grinding head is too high when grinding the glass end face inside the grinding base 5, the pressure can be released by controlling the pressure relief valve 6, thereby ensuring that the grinding base 5 can grind the glass normally.

[0038] like Figures 3 to 6As shown, the agitation mechanism includes two recovery pipes 7 fixedly installed on the front end face of the support base 2. The top ends of the two recovery pipes 7 extend into the liquid permeation tank 301. A collection tank 8 is provided below the receiving platform 3. A return pipe 9 is provided at the bottom of the collection tank 8. The end of the return pipe 9 away from the collection tank 8 is connected to the end of the coolant pipe 201. The outside of the return pipe 9 is connected to an external control pump body through a power line. In this embodiment, the collection tank 8 is a funnel, but it can also be other similar receiving and collecting structures.

[0039] During operation, when the coolant flows from the coolant pipe 201 to the glass grinding position, some of the coolant mixed with glass fragments will flow through the liquid permeation groove 301 inside the placement groove 4 into the recovery pipe 7 and into the collection tank 8. Then, the coolant below can flow back into the coolant pipe 201 through the return pipe 9, realizing the reuse of the coolant. The operation is relatively convenient.

[0040] like Figures 4 to 8 As shown, the stirring mechanism also includes a rotating vertical shaft 10 rotatably disposed inside the collection tank 8. A stirring blade 11 is fixedly installed on the outer circumference of the rotating vertical shaft 10. The rotating vertical shaft 10 is made of magnetic material, and a magnetic stirrer is disposed below the receiving platform 3. A waste pipe 12 is threadedly installed at the bottom of the collection tank 8, and the top end of the waste pipe 12 contacts the end of the return pipe 9. A filter screen 13 is disposed inside the return pipe 9 near the waste pipe 12. During operation, rotating the magnetic stirrer causes the magnetic rotating vertical shaft 10, which is also magnetic, to rotate to a certain extent. This rotation method is existing technology and will not be described in detail in this embodiment. Simultaneously, the stirring blade 11 rotates, causing it to agitate the coolant containing glass fragments in the collection tank 8. This allows the glass fragments to pass through the collection tank 8 and filter screen 13 quickly into the return pipe 9, preventing the collection tank 8 from becoming clogged due to the high viscosity of the coolant containing glass fragments. Furthermore, some glass fragments heavier than the buoyancy of the coolant will slide down the collection tank 8 into the waste pipe 12 and be stored there, while the cleaner coolant will then flow back into the coolant pipe 201 through the return pipe 9, facilitating the reuse of the coolant.

[0041] After a glass grinding process is completed, the waste inside can be processed by unscrewing the threaded waste tube 12.

[0042] It should be noted that the core component of a magnetic stirrer is a magnetically driven stir bar, usually made of magnetic material, which can rotate in response to changes in the external magnetic field. When the magnetic stirrer is working, the electromagnet at its bottom generates a rotating magnetic field. This rotating magnetic field acts on the magnetic rotating vertical shaft (i.e., the stir bar), causing it to rotate inside the container, thereby achieving the stirring effect. The rotation amplitude and speed of the magnetic rotating vertical shaft can be controlled by adjusting the stirrer settings to adapt to different experimental needs.

[0043] The discharge mechanism includes a placement plate 401 that is slidably installed on the side wall of the placement groove 4. The shape of the placement plate 401 is adapted to the shape of the glass to be ground. The receiving platform 3 is provided with a fixing unit inside, which is used to fix the glass to be ground.

[0044] During operation, when placing the glass to be ground, it is first placed in the placement groove 4 inside the placement plate 401, and then the glass can be fixed by the fixing unit. This ensures the stability of the glass during the grinding process and improves the subsequent glass forming effect.

[0045] like Figures 4 to 10 As shown, the fixing unit includes two sliding grooves 14 formed inside the receiving platform 3, arranged symmetrically with respect to the receiving platform 3. Each sliding groove 14 has an electric push rod 15 fixedly installed inside it. The telescopic end of the electric push rod 15 is fixedly installed with a clamping sleeve 16, and the outer surface of the clamping sleeve 16 is covered with a rubber sleeve. During operation, when the glass is placed on the surface of the placement plate 401, the electric push rod 15 inside the sliding groove 14 is moved by controlling the telescopic end of the two electric push rods 15 to drive the clamping sleeve 16 to move. Then, the two corresponding clamping sleeves 16 will clamp the glass. The clamping sleeves 16 not only protect the side wall of the glass, but also improve its stability during the grinding process, which is beneficial to the subsequent processing of the glass.

[0046] The discharge mechanism also includes a through groove 17 inside the receiving platform 3. Multiple L-shaped pushers 18 are slidably installed in the through groove 17. The side of the multiple L-shaped pushers 18 away from the through groove 17 is connected to the telescopic end of two electric push rods 15 respectively. The groove wall of the placement groove 4 is provided with a vertical groove 19. Both sides of the placement plate 401 are slidably installed inside the vertical groove 19 through rectangular blocks 20. Both sides of each rectangular block 20 are fixedly installed with a wedge block 21. The lower end face of each rectangular block 20 is fixedly installed with a limit spring 22. The end of the limit spring 22 away from the rectangular block 20 is fixedly installed inside the vertical groove 19. The placement plate 401 is fixedly installed between two rectangular blocks 20.

[0047] During operation, when the telescopic end of the electric push rod 15 moves the clamping sleeve 16, the telescopic end of the electric push rod 15 will simultaneously move the L-shaped push frame 18, causing the L-shaped push frame 18 to move towards the side closer to the wedge block 21. Then, the end of the L-shaped push frame 18 will press against the inclined surface of the wedge block 21, causing the wedge block 21 to move the rectangular block 20 and the placement plate 401 downwards. The rectangular block 20 presses down the limiting spring 22. After the clamping sleeve 16 has finished fixing the side wall of the glass, the placement plate 401 has also completely moved into the placement groove 4. This ensures that most of the coolant and glass fragments fall into the placement groove 4, ensuring the cleanliness of the entire grinding workbench 1.

[0048] After one grinding cycle is completed, the electric push rod 15 is controlled to move the clamping sleeve 16 away from the glass sidewall. The electric push rod 15 will also move the L-shaped pusher 18 away from the wedge block 21. When the L-shaped pusher 18 is completely disengaged from the wedge block 21, the limit spring 22, which is under pressure, returns to its original state and moves the placement plate 401 away from the placement groove 4. This avoids the glass from being too close to the groove wall of the placement groove 4, which would make it difficult to remove the glass later. The operation is more convenient.

[0049] A rotating bead 23 is rotatably mounted on the side of the L-shaped pusher 18 near the rectangular block 20. The rotating bead 23 contacts the side wall of the wedge block 21. During operation, the rotating bead 23 facilitates the L-shaped pusher 18 to press the wedge block 21 when it contacts it, thereby facilitating the downward movement of the shelf 401 and its complete placement inside the placement groove 4.

[0050] The sidewall of the rectangular block 20 is slidably installed inside the vertical groove 19 via the limiting post 24, and the vertical groove 19 has a groove that matches the limiting post 24. During operation, the limiting post 24 is provided to ensure that the rectangular block 20 is on a straight axis when it moves, which facilitates the subsequent polishing of the glass.

[0051] The outside of the return pipe 9 is connected to an external control pump via a power cord. A sealing sleeve is provided at the contact point between the return pipe 9 and the coolant pipe 201. During operation, the clean coolant inside the return pipe 9 can be easily introduced into the coolant pipe 201 via the external pump.

[0052] During operation, the glass to be ground is placed inside the placement groove 4 of the receiving platform 3. Then, the grinding head is moved closer to the glass by the drive seat inside the grinding base 5, and the grinding head is controlled to grind the end face of the glass. The grinding method and driving method of the grinding base 5 are existing technologies and will not be described in detail here. During the glass grinding process, the coolant is drawn from the coolant pipe 201 by the control of the external pump and flows to the grinding position on the end face of the glass. Then, the stirring mechanism can stir the glass fragments and coolant after use. This process accelerates the recycling of the glass and allows for the automatic removal of the ground glass via the discharge mechanism, preventing the glass from sticking too closely to the wall of the placement groove 4 and making it difficult to remove. When the coolant flows from the coolant pipe 201 to the glass grinding position, some of the coolant mixed with glass fragments will flow through the liquid permeation groove 301 inside the placement groove 4 into the recycling pipe 7 and then into the collection tank 8. Subsequently, the coolant below can flow back into the coolant pipe 201 through the return pipe 9, enabling the coolant to be reused. The operation is quite convenient.

[0053] By energizing the magnetic stirrer and causing it to rotate, the vertical shaft 10, which is also magnetic, will rotate to a certain extent. This rotation method is existing technology and will not be described in detail in this embodiment. The rotation of the vertical shaft 10 will simultaneously drive the stirring blade 11 to rotate, so that the stirring blade 11 will agitate the coolant mixed with glass fragments in the collection tank 8. This allows the glass fragments to pass through the collection tank 8 and the filter screen 13 as quickly as possible into the return pipe 9, avoiding the problem of the collection tank 8 becoming clogged due to the high viscosity of the coolant containing glass fragments. Moreover, some glass fragments whose weight is greater than the buoyancy of the coolant will slide into the waste pipe 12 along the collection tank 8 and be stored in the waste pipe 12 under the obstruction of the filter screen 13. Then, the cleaner coolant will enter the coolant pipe 201 again along the return pipe 9, which is convenient for the reuse of the coolant.

[0054] When the glass is placed on the surface of the shelf 401, the electric push rods 15 inside the sliding groove 14 are moved by controlling the movement of the two electric push rods 15. This causes the telescopic ends of the two electric push rods 15 to move the clamping sleeves 16. Then, the two corresponding clamping sleeves 16 will clamp the glass. The clamping sleeves 16 not only protect the sidewalls of the glass, but also improve its stability during the grinding process, which is beneficial for subsequent processing of the glass. When the telescopic ends of the electric push rods 15 move the clamping sleeves 16, the telescopic ends of the electric push rods 15 will simultaneously move the clamping sleeves 16. The L-shaped pusher 18 moves, causing it to move closer to the wedge block 21. Then, the end of the L-shaped pusher 18 will press against the inclined surface of the wedge block 21, causing the wedge block 21 to move the rectangular block 20 and the placement plate 401 downward. The rectangular block 20 presses down the limiting spring 22. After the clamping sleeve 16 has finished fixing the side wall of the glass, the placement plate 401 has also moved completely into the placement groove 4. This ensures that most of the coolant and glass fragments fall into the placement groove 4, ensuring the cleanliness of the entire grinding workbench 1.

[0055] After one grinding cycle is completed, the electric push rod 15 is first controlled to move the clamping sleeve 16 away from the glass sidewall, and the electric push rod 15 will move the L-shaped pusher 18 away from the wedge block 21. When the L-shaped pusher 18 is completely disengaged from the wedge block 21, the limit spring 22, which is under pressure, returns to its original state and moves the placement plate 401 away from the placement groove 4. This avoids the glass from being too close to the groove wall of the placement groove 4, which would make it difficult to remove the glass later. The operation is more convenient. A rotating bead 23 is provided so that when the L-shaped pusher 18 contacts the wedge block 21, it can squeeze the wedge block 21, thereby making it easier for the placement plate 401 to move down and be completely placed inside the placement groove 4.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
