Abstract
Description
Technical Field
[0001] This invention relates to the field of glass substrate processing equipment technology, and specifically to a glass substrate harpoon-type grinding worktable. Background Technology
[0002] Liquid crystal substrates typically refer to high-precision, high-performance substrate materials used in semiconductors, display panels, optoelectronics, and other fields. With the continuous development of electronic technology, high-generation substrates are widely used in various electronic products, including liquid crystal display panels and organic light-emitting diode panels.
[0003] In the LCD substrate manufacturing process, the grinding process mainly involves deep grinding of the substrate edges. Currently, when grinding high-generation substrates, the substrate is first transported to a grinding transfer table. After the long and short sides are ground and the substrate is centered, it is then transferred by a robotic arm to the bottom of the grinding mechanism and positioned. The grinding mechanism then grinds the edges of the substrate. After grinding one side of the substrate, it is transferred by a robotic arm to the transfer table, where the substrate is oriented and centered. Finally, it is transferred by a robotic arm to the bottom of the grinding mechanism for grinding. The overall grinding process for all four sides of the substrate is quite cumbersome, which prolongs the processing time and reduces processing efficiency.
[0004] Therefore, this application proposes a harpoon-type grinding stage for glass substrates. Summary of the Invention

[0019] This invention provides a harpoon-type grinding stage for glass substrates. Compared with the prior art, it has the following advantages:
[0020] 1. When processing the edges of the substrate, the number of times the substrate is transferred is reduced, which facilitates the grinding of the substrate edges. The overall grinding process of the four sides of the substrate is simpler, thereby shortening the processing time and improving processing efficiency.

[0022] 3.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Example 1
[0036] To address the technical problems in the background art, the following harpoon-type grinding stage for glass substrates is provided:
[0037] Combination Figures 1-9As shown, the present invention provides a harpoon-type grinding worktable for glass substrates, including two frames 1 arranged symmetrically. A mounting base 11 is fixedly installed on the top of each frame 1, and a vacuum stage 12 is installed on the top of each mounting base 11. The vacuum stage 12 includes a vacuum chamber 121 with an open top, fixedly installed on the top of the mounting base 11. A cover 122 for sealing the opening of the vacuum chamber 121 is fixedly installed on the top of the vacuum chamber 121 by screws. Support units are installed on the mounting base 11 on the side of each vacuum chamber 121 that is close to each other. Each support unit includes multiple support rods 13 linearly arrayed and fixedly installed on the mounting base 11 along the length of the frame 1. The side of the support rods 13 away from the vacuum chamber 121 is fixed by a connecting plate 14. A vacuum suction cup 15 is fixedly installed. A ventilation chamber 131 is opened in the support rod 13. A connecting pipe 132 connected to the ventilation chamber 131 is fixedly installed at one end of the support rod 13. The other end of the connecting pipe 132 is connected to the vacuum suction cup 15. A connecting pipe 133 connected to the ventilation chamber 131 is fixedly installed at the other end of the support rod 13. The other end of the connecting pipe 133 is connected to the vacuum box 121 and extends into the vacuum box 121. A solenoid valve 134 is fixedly installed at one end of the connecting pipe 133 extending into the vacuum box 121. A pump box 16 connected to the inside of the vacuum box 121 is fixedly installed on the frame 1. It is worth noting that a negative pressure pump is installed in the pump box 16. A base plate is placed on the top of the multiple support rods 13 of the two support units.
[0038] A groove 135 is provided on one side of the support rod 13 along the direction of the connecting plate 14. An installation block 2 is slidably installed on one side of the support rod 13 and within the groove 135 via an electric slider. A limiting member 21 is installed on the top of the installation block 2. The limiting member 21 extends above the support rod 13. Multiple sets of limiting members 21 are used to limit the substrate placed on multiple support rods 13 so that the substrate is placed centrally on multiple support rods 13.
[0039] A mounting bracket 3 is installed on the outer side of the two frames 1, which is sleeved on the top of the two frames 1. A horizontal slide rail 31 is fixedly installed on the inner top wall of the mounting bracket 3 and directly above the two frames 1. A sliding block 32 is slidably installed on the bottom of the slide rail 31. An electromagnetic slider 33 connected to the sliding block 32 is fixedly installed on the slide rail 31. A horizontal slide rail 34 is fixedly installed on the bottom of the sliding block 32. A sliding block 35 is slidably installed on the bottom of the slide rail 34. An electromagnetic slider 36 connected to the sliding block 35 is fixedly installed on the slide rail 34. A grinding mechanism 4 is installed on the bottom of the sliding block 35, which is used to grind the edge of the substrate placed on the multiple support rods 13. A rotation and translation mechanism 5 is installed on the mounting bracket 3, which is used to rotate or translate the substrate placed on the multiple support rods 13.
[0040] During the grinding process of the substrate edge, the substrate is transported onto multiple support rods 13 of two sets of support units, with each side of the substrate positioned between two adjacent support rods 13. At this time, the substrate contacts multiple vacuum suction cups 15 at the ends of the support rods 13. Multiple electric sliders located on both sides of the substrate cause the mounting blocks 2 to move simultaneously along the slide grooves 135 towards the substrate. As the mounting blocks 2 move, they drive multiple limiting members 21 to move and contact the substrate. When the limiting members 21 on both sides of the substrate are in contact with the substrate, the substrate placed on the support rods 13 is positioned to limit its movement. The substrate is placed centrally on multiple support rods 13. At this time, the solenoid valve 134 connected to the ventilation chamber 131 of the support rod 13 in contact with the substrate within the vacuum chamber 121 is opened, while the other solenoid valves 134 are closed. Then, the negative pressure pump in the pump box 16 is activated, drawing air out of the vacuum chamber 121 and creating a negative pressure. Air from the multiple vacuum suction cups 15 flows into the vacuum chamber 121 through the ventilation chambers 131 of the support rods 13, thus enabling the multiple vacuum suction cups 15 to perform negative pressure positioning on the substrate. Meanwhile, the electromagnetic slider 33 moves the sliding block 32... The bottom of slide rail 31 slides, causing the grinding mechanism 4 to move between the two support rods 13 and contact the edge of the substrate. Then, the electromagnetic slider 36 moves the slider 35 at the bottom of slide rail 34, driving the grinding mechanism 4 to move between the two support rods 13, thus achieving the grinding process on the edge of the substrate. After the grinding process between the two support rods 13 and the edge of the substrate is completed, the electromagnetic sliders 33 and 36 work together to grind the edges on the opposite sides. After the grinding process on both sides of the substrate located between the two adjacent support rods 13 is completed, the pump box 16 is controlled. The negative pressure pump is turned off, canceling the negative pressure positioning of the substrate. The substrate is rotated by the rotation and translation mechanism 5, and with the cooperation of the rotation and translation mechanism 5 in translating the substrate, the other two sides of the substrate are respectively located between two adjacent support rods 13. Similarly, the negative pressure positioning of the substrate and the grinding operation of the other two sides of the substrate can be realized. In summary, when processing the edge of the substrate, the number of times the substrate is transferred is reduced, which facilitates the grinding operation of the edge of the substrate. The overall grinding process of the four sides of the substrate is relatively simple, thereby shortening the processing time and improving the processing efficiency.
[0041] In this embodiment, the limiting member 21 includes a vertical column 211 fixedly installed on the top of the mounting block 2. An annular rubber block 212 is sleeved on the outside of the column 211. A limiting bolt 213 for limiting the annular rubber block 212 is threadedly connected to the top of the column 211. By removing the limiting bolt 213, the limiting of the annular rubber block 212 can be removed, making it easy to disassemble and replace the annular rubber block 212. In use, the mounting block 2 is moved towards the substrate simultaneously along the slide groove 135 by multiple electric sliders located on both sides of the substrate. When the mounting block 2 moves, the annular rubber block 212 is moved by the column 211. When the annular rubber blocks 212 on both sides of the substrate are in contact with the substrate, the substrate placed on the multiple support rods 13 can be limited, so that the substrate is placed in the center on the multiple support rods 13.
[0042] In this embodiment, the grinding mechanism 4 includes a mounting plate 41 fixedly installed at the bottom of the sliding block 35. Vertical telescopic rods 42 are symmetrically fixedly installed at the bottom of the mounting plate 41. A connecting frame 43 is fixedly installed at the bottom of the two telescopic rods 42. A drive rod 44 connected to the connecting frame 43 is fixedly installed at the bottom of the mounting plate 41. A support plate 45 is installed at the bottom of the connecting frame 43. A horizontal mounting shaft 46 is rotatably mounted on the support plate 45. A grinding disc 47 is detachably fixed to one end of the mounting shaft 46 by screws. A motor 48 for driving the mounting shaft 46 to rotate is fixedly installed on the support plate 45. In use, the edge of the substrate located between two adjacent support rods 13 is ground. During grinding, the electromagnetic slider 33 causes the sliding block 32 to slide at the bottom of the slide rail 31, displacing the grinding disc 47 above the edge of the substrate between the two support rods 13. At this time, the drive rod 44 causes the connecting frame 43 to move downward along the two telescopic rods 42, inserting the grinding disc 47 between the two support rods 13. Then, the electromagnetic slider 33 makes the grinding disc 47 contact the edge of the substrate. The control motor 48 is turned on, causing the mounting shaft 46 to rotate on the support plate 45, driving the grinding disc 47 to rotate and grind the substrate. At this time, the electromagnetic slider 36 causes the sliding block 35 to move at the bottom of the slide rail 34, thereby driving the grinding disc 47 to move between the two support rods 13, thus realizing the grinding of the edge of the substrate.
[0043] Example 2
[0044] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:
[0045] In this embodiment, the rotation and translation mechanism 5 includes a slide rail 3 51 fixedly installed on the inner top wall of the mounting frame 3 and located on one side of the slide rail 1 31. The slide rail 3 51 is the same length as the slide rail 1 31. A sliding block 3 52 is slidably installed on the bottom of the slide rail 3 51. An electromagnetic slider 3 53 connected to the sliding block 3 52 is fixedly installed on the slide rail 3 51. A mounting plate 2 54 is fixedly installed on the bottom of the sliding block 3 52. Vertical telescopic rods 2 55 are symmetrically fixed on the bottom of the mounting plate 2 54. A connecting frame 2 56 is fixedly installed on the bottom of the two telescopic rods 2 55. The bottom of the mounting plate 2 54... A drive rod 541 connected to a connecting frame 56 is fixedly installed. A vertically oriented rotating shaft 561 is rotatably mounted on the connecting frame 56. A fixing bracket 562 is fixedly mounted at the bottom of the rotating shaft 561. A motor 563 for driving the rotating shaft 561 to rotate is fixedly mounted on the connecting frame 56. A horizontal plate 57 is fixedly mounted at the bottom of the fixing bracket 562. A cavity 571 is opened inside the horizontal plate 57. Multiple vacuum suction cups 58, each communicating with the inside of the cavity 571, are fixedly mounted at the bottom of the horizontal plate 57. A device communicating with the inside of the cavity 571 is fixedly mounted at the top of the horizontal plate 57. The connected negative pressure pipe 59 is noteworthy because its other end is connected to an external negative pressure device. During use, the electromagnetic slider 53 causes the sliding block 52 to slide at the bottom of the slide rail 51, positioning the horizontal plate 57 above the substrate. The drive rod 541 causes the connecting frame 56 to move downwards along the two telescopic rods 55, ensuring that multiple vacuum suction cups 58 contact the substrate. Then, the external negative pressure device draws air out of the cavity 571 through the negative pressure pipe 59, creating negative pressure within the cavity 571 and consequently within the multiple vacuum suction cups 58. Due to the vacuum... All suction cups 2 58 are in contact with the substrate, thus the substrate can be fixed by multiple vacuum suction cups 2 58. At this time, the connecting frame 2 56 is moved upward along the two telescopic rods 2 55 by the driving rod 2 541, so that the substrate is not in contact with the vacuum suction cup 1 15. The sliding block 3 52 is moved at the bottom of the slide rail 3 51 by the electromagnetic slider 3 53, so that the substrate can be translated. When it is necessary to rotate the substrate, the rotating shaft 561 is rotated by the motor 2 563, so that the horizontal plate 57 can be rotated by the fixing frame 562, thus realizing the rotation of the substrate, which is easy to control.
[0046] In this embodiment, the two ends of slide rail 31 and slide rail 51 extend to the outer sides of the two frames 1 respectively. A vertical rotating rod 451 is fixed to the top of the support plate 45. The support plate 45 is rotatably mounted on the bottom of the connecting frame 43 via the rotating rod 451. A motor 431 for driving the rotating rod 451 to rotate is fixedly mounted on the connecting frame 43. By setting the two ends of slide rail 31 and slide rail 51 to extend to the outer sides of the two frames 1 respectively, and then using electromagnetic slider 33 to make sliding block 32 slide at the bottom of slide rail 31, the grinding mechanism 4 is moved to grind the edge of the substrate. When grinding the substrate edge, the sliding block 52 can be made to slide at the bottom of slide rail 51 by electromagnetic slider 53, so that the horizontal plate 57 is moved to the two frames 1. On one side of the outer edge, the grinding mechanism 4 is moved to make way for the grinding mechanism 4. Conversely, when the substrate placed on multiple support rods 13 is rotated or translated by the rotation and translation mechanism 5, the sliding block 32 can be slid at the bottom of the slide rail 31 by the electromagnetic slider 33, so that the grinding mechanism 4 is moved to the outer edge of the two frames 1, thus making way for the rotation and translation mechanism 5. By setting the support plate 45 to be rotatably installed at the bottom of the connecting frame 43 via the rotating rod 451, when grinding the edge of the substrate, the motor 3 431 can be controlled to work to make the rotating rod 451 rotate, thereby driving the support plate 45 to rotate around the rotating rod 451, so that the side of the grinding disc 47 away from the support plate 45 contacts the edge of the substrate, which is beneficial for grinding the edge of the substrate.
[0047] In this embodiment, the top of the support rod 13 has several ventilation holes 136 that are connected to the inside of the ventilation chamber 131. A sealing member 6 is installed on the support rod 13 and inside the ventilation holes 136. It is used to seal or unseal the multiple ventilation holes 136. Specifically, in this embodiment, the pump box 16 is also equipped with an air supply pump. By setting the ventilation holes 136, after the edge of the substrate is ground, the substrate is transferred to one side of the two frames 1 by the rotation and translation mechanism 5. When the substrate is transferred to the next processing step by the external vacuum suction cup robot, gas is supplied to the vacuum box 121 by the air supply pump in the pump box 16 and the solenoid valves 134 in the vacuum box 121 are fully opened. At this time, the gas in the vacuum box 121 flows into the ventilation chamber 131 and is discharged upward through the ventilation holes 136 at the top of the support rod 13, thereby blowing onto the substrate and achieving the effect of cleaning the dust adhering to the edge of the substrate during the grinding process.
[0048] Example 3
[0049] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:
[0050] In this embodiment, the sealing component 6 includes a sealing plate 61. A mounting groove 137, communicating with the interior of the ventilation chamber 131, is provided on the side of the support rod 13 near the vacuum chamber 121 and above the connecting pipe 133. The sealing plate 61, which is in contact with the top wall of the ventilation chamber 131, is slidably installed inside the ventilation chamber 131. The sealing plate 61 has several through holes 611, which can be connected to several ventilation holes 136 respectively. A sealing block 138 for sealing the mounting groove 137 is fixedly installed on the support rod 13. It is worth noting that when the sealing block 138 seals the mounting groove 137, the sealing block 138... A drive rod 62 connected to the sealing plate 61 is fixedly installed on the sealing block 138 and located in the ventilation cavity 131, fitting the cross section between the support rod 13 and the sealing block 138. In use, when the sealing of multiple ventilation holes 136 is removed, the sealing plate 61 is slid in the ventilation cavity 131 by the drive rod 62, so that multiple perforations 611 are connected to multiple ventilation holes 136 respectively, thus removing the sealing of ventilation holes 136. Conversely, when the sealing plate 61 is slid in the ventilation cavity 131 by the drive rod 62, multiple perforations 611 are connected to one side of multiple ventilation holes 136 respectively, thus achieving the sealing effect of multiple ventilation holes 136.
[0051] In this embodiment, a spraying mechanism 7 is installed on one side of each of the two frames 1. The spraying mechanism 7 includes a support plate 71 fixedly installed on one side of the frame 1. A vertical water inlet pipe 72 is fixedly installed on the support plate 71 and is connected to an external cleaning fluid delivery device. A positioning frame 73 is rotatably installed on the support plate 71 above the water inlet pipe 72. A motor 74 for driving the positioning frame 73 to rotate is fixedly installed on the support plate 71. A water pipe 75 is fixedly installed on the positioning frame 73. Multiple nozzles 76, all connected to the inside of the water pipe 75, are linearly arrayed along its length. When the water pipe 75 is horizontal, the multiple nozzles 76 are located directly below the water pipe 75. The water pipe 75 is connected to the water inlet pipe 72 through a connecting hose 77. By setting up the spraying mechanism 7, the edges of the substrate are ground. After processing, the substrate is transferred to one side of the two frames 1 by the rotation and translation mechanism 5, and then transferred to the next processing step by the external vacuum suction cup robot. During this process, the substrate is moved towards the spraying mechanism 7. During this process, the positioning frame 73 is rotated on the two support plates 71 by the two motors 74, so that the ends of the two water pipes 75 are close to each other and are horizontal. The external cleaning fluid delivery equipment is controlled to deliver cleaning fluid to the water inlet pipe 72. The cleaning fluid enters the water pipe 75 through the connecting hose 77 and is sprayed downward through multiple nozzles 76. When the substrate is transferred to one side of the two frames 1 by the rotation and translation mechanism 5, and then transferred to the next processing step by the external vacuum suction cup robot, the substrate is moved below the two water pipes 75, so that the cleaning fluid sprayed by the nozzles 76 can be sprayed onto the substrate, achieving the cleaning effect on the edge of the substrate.
[0052] In this embodiment, an arc-shaped groove 711 is formed on the bearing plate 71, and a support rod 731 is fixedly installed on one side of the positioning frame 73. The support rod 731 is slidably hinged to the arc-shaped groove 711. When the water pipe 75 is horizontal, the support rod 731 is located at the bottom end of the arc-shaped groove 711. By setting the arc-shaped groove 711 and the support rod 731, when the water pipe 75 is horizontal, the support rod 731 is located at the bottom end of the arc-shaped groove 711, thereby achieving the effect of supporting the support rod 731 through the bearing plate 71. The positioning frame 73 supports the water pipe 75, increasing its stability. A snap-fit mechanism 8 is installed at the end of each of the two water pipes 75 away from the inlet pipe 72. This mechanism is used to snap or unsnap the two water pipes 75 together. By setting the snap-fit mechanism 8, the two water pipes 75 can be snapped together, forming a single unit. The ends of the two water pipes 75 are snapped and fixed, further increasing their stability.
[0053] In this embodiment, the locking mechanism 8 includes a positioning frame 81 and a positioning block 82. The positioning frame 81 is fixedly installed at the ends of both water pipes 75 away from the inlet pipe 72. Positioning blocks 82 are rotatably connected to both positioning frames 81. One positioning block 82 has a slot 821, and the other positioning block 82 has a fixedly installed locking block 822 that can engage with the slot 821. A motor 83 for driving the positioning block 82 to rotate is fixedly installed on one of the positioning frames 81. When both water pipes 75... When in a horizontal position, the locking block 822 can be inserted into the locking slot 821 and engaged with it. In use, when both water pipes 75 are in a horizontal position, the locking block 822 is inserted into the locking slot 821. At this time, the control motor 83 works, causing the positioning block 82 connected to it to rotate on the positioning frame 81. The locking block 822 engages with the locking slot 821, thereby driving the other positioning block 82 to rotate on the other positioning frame 81, making the locking slot 821 horizontal, thus achieving the effect of locking and fixing the ends of the two water pipes 75.
