Description

Technical Field

[0001] This invention belongs to the field of liquid crystal glass panel processing technology, and in particular relates to a polishing equipment and polishing method for liquid crystal glass panel processing. Background Technology

[0002] The LCD panel is the core component of an LCD monitor, accounting for approximately 80% of the total cost. Its structure includes the LCD panel and backlight system, achieving 16.7 million colors through red, green, and blue color filters. The manufacturing technology is divided into front-end array processing, mid-end cell processing, and back-end module assembly, requiring over 300 dust-free precision processes. The main types include TN, IPS, and VA technologies. TN panels have a fast response time but a narrower viewing angle, while IPS and VA panels offer wide viewing angles and high color accuracy.

[0003] In the production of LCD glass panels, surface polishing is required. However, existing LCD glass panel polishing equipment can only polish one side at a time. Polishing the back requires stopping the machine, flipping the LCD glass panel, and then re-fixing it. This is not only cumbersome but also reduces polishing efficiency. Furthermore, polishing debris adheres to the LCD glass surface, requiring further cleaning after polishing to ensure the panel's cleanliness. Therefore, we provide a polishing device and method for LCD glass panel processing to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a polishing device and method for processing liquid crystal glass panels. By controlling a first motor to drive a first worm gear to rotate, which in turn drives a second worm wheel meshing with it to rotate, thereby driving a second polishing roller to rotate. Under the action of a first locking block engaging with a first locking slot, the first worm gear drives the second worm gear to rotate via a cylindrical tube, causing the second worm gear to mesh and drive the first worm wheel to rotate, which in turn drives the first polishing roller to rotate. During the height adjustment of the second polishing roller, the first and second polishing rollers can simultaneously polish the upper and lower surfaces of the liquid crystal glass panel, effectively improving the efficiency of polishing. To improve grinding efficiency, the use of the first and second cleaning components effectively removes grinding debris, ensuring the cleanliness of the LCD glass panel. This solves the problem of existing LCD glass panel grinding equipment, which can only grind one side during operation. When grinding the back side, the equipment needs to be stopped, the LCD glass panel flipped over, and then re-fixed, which is not only cumbersome but also affects grinding efficiency. In addition, the grinding debris generated during the grinding process adheres to the LCD glass surface, requiring cleaning again after grinding, thus addressing the issue of LCD glass panel cleanliness.

[0017] This invention also includes a polishing method for processing liquid crystal glass panels, comprising the following steps: S01: First, place the LCD glass plate on the operating table between the two positioning plates. Then, energize each electromagnet to move the clamping plate closer to the outer wall of the LCD glass, thus completing the fixing and clamping of it. S02: Next, control the second polishing roller to move downwards, so that the second polishing roller is in contact with the upper surface of the liquid crystal glass plate. Initially, the position of the first polishing roller is in contact with the lower surface of the liquid crystal glass plate. Then, control the first polishing roller and the second polishing roller to rotate, so as to simultaneously polish the upper and lower surfaces of the liquid crystal glass plate. S03: Then, the first cleaning component and the second cleaning component work together to collect and clean the debris generated during the polishing process; S04: By controlling the operation of the power component, the bidirectional threaded rod drives the two moving plates to move, and then the positioning plate drives the liquid crystal glass panel to move in the horizontal direction, thereby achieving the polishing of the entire upper and lower surfaces of the liquid crystal glass panel.

[0018] The present invention has the following beneficial effects: 1. By setting up a grinding component, the present invention controls the first motor to drive the first worm to rotate, which in turn drives the second worm wheel meshing with it to rotate, thereby driving the second grinding roller to rotate. Under the action of the first locking block and the first locking groove, the first worm drives the second worm to rotate through the cylindrical tube, so that the second worm meshes with and drives the first worm wheel to rotate, which in turn drives the first grinding roller to rotate. During the process of the second grinding roller adjusting its height, the first grinding roller and the second grinding roller can simultaneously grind the upper and lower surfaces of the liquid crystal glass plate, effectively improving the grinding efficiency.

[0019] 2. This invention, by setting up a first cleaning component and a second cleaning component, controls two first cleaning rollers to converge towards each other. A rod on one of the first cleaning rollers is inserted into a cylindrical groove on the other first rotating rod, causing a corresponding locking rod on the rod to engage with a second locking groove inside the cylindrical groove, thus achieving docking of the two first cleaning rollers. Simultaneously, the two first cleaning rollers can rotate synchronously. The rotating first cleaning rollers clean the debris generated during the polishing of the upper surface of the liquid crystal glass panel, sweeping the debris into a first collection box. Debris generated during the polishing of the lower surface of the liquid crystal glass panel by the first polishing roller falls directly into a second collection box. With the operation of two fans, the debris is adsorbed into the second collection box, thereby improving the cleaning effect and ensuring the cleanliness of the liquid crystal glass panel.

[0020] 3. This invention applies current to an electromagnet, causing it to generate magnetic force that attracts a corresponding iron plate towards the outer wall of the liquid crystal glass panel. Then, the first L-shaped plate moves the clamping plates towards the outer wall of the liquid crystal glass panel, allowing the four clamping plates to securely hold the liquid crystal glass panel. During this process, each first spring is in a stretched state to ensure the stability of the liquid crystal glass panel during movement and polishing, thereby improving the polishing effect. By controlling the movement of the two positioning plates along the direction of the first guide groove, the liquid crystal glass panel is moved along the direction of the first guide groove, thus achieving uniform feeding of the liquid crystal glass panel during polishing and improving the consistency and efficiency of polishing.

Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0025] Example 1, please refer to Figure 1-16The present invention provides the following technical solution: a grinding device for processing liquid crystal glass panels, comprising a positioning and clamping assembly 1, a grinding assembly 2 disposed on the positioning and clamping assembly 1, two first cleaning assemblies 3 symmetrically disposed on the positioning and clamping assembly 1, a second cleaning assembly 4 disposed below the positioning and clamping assembly 1, a power assembly 5 disposed at the bottom of the positioning and clamping assembly 1, and a transmission assembly 7 disposed at the bottom of the positioning and clamping assembly 1; the positioning and clamping assembly 1 is used for positioning and clamping the liquid crystal glass panel; the grinding assembly 2 is used for simultaneously grinding the upper and lower surfaces of the liquid crystal glass panel; the first cleaning assemblies 3 are used for cleaning the debris generated during grinding the upper surface of the liquid crystal glass panel; the second cleaning assembly 4 is used for cleaning the debris generated during grinding the lower surface of the liquid crystal glass panel; the power assembly 5 is used for providing power for the movement of the positioning assembly; and the transmission assembly 7 provides power for the operation of the two first cleaning assemblies 3.

[0026] Positioning and clamping assembly 1 includes an operating table 101, with several support columns 102 symmetrically fixedly connected to the bottom of the operating table 101, and two linearly distributed first guide grooves 103 (e.g., ...) through the top of the operating table 101. Figure 3 (The length of the first guide groove 103 on the left is less than the length of the first guide groove 103 on the right). Symmetrically distributed second guide grooves 104, perpendicular to the two first guide grooves 103, are provided on the top of the operating table 101. A rectangular slot 105, perpendicular to the first guide grooves 103, is provided through the top of the operating table 101. A movable plate 106 is slidably connected to the inner wall of the second guide groove 104. A control box 107 is fixedly connected to the top of the operating table 101. A positioning plate 108 is fixedly connected to the top of the movable plate 106. A first sliding groove 109 is symmetrically provided on one side of the positioning plate 108. The first sliding groove 109 is fixedly connected to the opposite sides of the two sides. A guide rod 110 is fixedly connected, and a first L-shaped plate 111 that slides and engages with a first sliding groove 109 is slidably sleeved on the outer wall of the guide rod 110. A clamping plate 112 is fixedly connected to the end of the first L-shaped plate 111, and a first spring 113 sleeved on the guide rod 110 is fixedly connected between the first L-shaped plate 111 and the first sliding groove 109.

[0027] The operation process of this embodiment is as follows: First, the liquid crystal glass plate is placed on the operating table 101 and positioned between the two positioning plates 108. Then, each electromagnet 115 is energized, causing the electromagnet 115 to attract the corresponding iron plate 114 to move towards the outer wall of the liquid crystal glass plate. Then, the clamping plate 112 is moved towards the outer wall of the liquid crystal glass plate by the first L-shaped plate 111, so that the four clamping plates 112 can fix and clamp the liquid crystal glass plate. During this process, each first spring 113 is stretched to ensure the stability of the liquid crystal glass plate during movement and polishing, thereby improving the polishing effect. By controlling the two positioning plates 108 to move along the direction of the first guide groove 103, the liquid crystal glass plate is moved along the direction of the first guide groove 103, thereby achieving uniform feeding during the polishing of the liquid crystal glass plate, thereby improving polishing consistency and polishing efficiency.

[0028] Example 2, please refer to Figure 1-16 This second embodiment improves upon the first embodiment as follows: the grinding assembly 2 includes a U-shaped frame 201 fixedly connected to the top of the operating table 101. A cylinder 202 is fixedly connected to the top of the U-shaped frame 201, and a horizontal plate 203 is fixedly connected to the output end of the cylinder 202. The grinding assembly 2 also includes mounting plates 204 fixedly connected to opposite sides of the rectangular slot 105. A first rotating shaft 205 is rotatably connected between the two mounting plates 204, and a first grinding roller 206 is fixedly connected to the outer wall of the first rotating shaft 205. A second sliding groove 207 is provided on one side of the mounting plate 204, and a slider 208 is slidably connected to the inner wall of the second sliding groove 207. A second rotating shaft 209 is rotatably connected between the two sliders 208, and a second grinding roller 210 is fixedly connected to the outer wall of the second rotating shaft 209. A first worm gear 211 is fixedly connected to the outer wall of the first rotating shaft 205, and a second worm gear 212 is fixedly connected to the outer wall of the second rotating shaft 209. A connecting rod 213 is fixedly connected to the top of the 08, and the connecting rod 213 is fixedly engaged with the horizontal plate 203. A mounting base 214 is fixedly connected to one side of the horizontal plate 203. A first motor 215 is fixedly connected to the bottom of the mounting base 214. A first worm gear 216 is fixedly connected to the output end of the first motor 215. A support plate 217 is fixedly connected to one side of the mounting plate 204. A second worm gear 218 is rotatably connected to the top of the support plate 217. First locking blocks 219 are symmetrically fixedly connected to the outer walls of the first worm gear 216 and the second worm gear 218. A first fixing plate 220 is fixedly connected to one side of the mounting plate 204. A cylindrical tube 221 is rotatably connected through the top of the first fixing plate 220. The inner wall of the cylindrical tube 221 is symmetrically provided with first locking grooves 222 that slide with each first locking block 219. The first worm gear 216 meshes with the second worm wheel 212, and the second worm gear 218 meshes with the first worm wheel 211.

[0029] The operation process of this embodiment is as follows: After the liquid crystal glass plate is positioned and clamped, the first polishing roller 206 initially adheres tightly to the lower surface of the liquid crystal glass plate. Then, the control cylinder 202 drives the horizontal plate 203 to move downward, which in turn drives the second polishing roller 210 to move downward through the connecting rod 213 and the slider 208, so that the second polishing roller 210 abuts against the upper surface of the liquid crystal glass plate. At the same time, during the downward movement of the horizontal plate 203, the horizontal plate 203 drives the first motor 215 to move downward through the mounting base 214, which in turn drives the first worm gear 216 to move downward. During the downward movement of the first worm gear 216, the second worm wheel 212 on the second rotating shaft 209 moves downward synchronously with it, thereby ensuring that the first worm gear 216 is always in a meshing state with the second worm wheel 212. Then, the first motor 215 is started, causing the first motor 216 to move downward. The first worm gear 216 rotates, which in turn drives the second worm wheel 212 meshing with it to rotate. This, in turn, drives the second polishing roller 210 to rotate via the second rotating shaft 209. Through the engagement of the first locking block 219 on the first worm gear 216 and the first locking groove 222 inside the cylindrical tube 221, the first worm gear 216 drives the cylindrical tube 221 to rotate. Simultaneously, the cylindrical tube 221 drives the second worm gear 218 to rotate. The second worm gear 218 meshes with and drives the first worm wheel 211 to rotate. This, in turn, drives the first polishing roller 206 to rotate via the first rotating shaft 205. During the height adjustment process of the second polishing roller 210, the first polishing roller 206 and the second polishing roller 210 can simultaneously polish the upper and lower surfaces of the liquid crystal glass plate, effectively improving polishing efficiency.

[0031] The operation process in this embodiment is as follows: Figure 1 , 8As shown, during the polishing process of the liquid crystal glass panel being pushed from left to right, the right-side positioning plate 108 drives the two toothed plates 117 to move synchronously to the right, causing the toothed plates 117 to mesh and drive the spur gear 319 to rotate, which in turn drives the lead screw 302 to rotate. The lead screw 302, through the second L-shaped plate 303, drives the first collection box 304 and the first cleaning roller 308 to converge towards each other. After the right-side positioning plate 108 passes the first collection box 304, the two first collection boxes 304 are brought together, and at the same time, the two first cleaning rollers 308 are docked. At this time, the first collection box 304 and the first cleaning roller 308 are fitted above the liquid crystal glass panel. During the docking process of the two first cleaning rollers 308, the insertion rod 312 on one of the first cleaning rollers 308 is inserted into the cylindrical groove 309 on the other first rotating rod 307, causing the locking rod 31 on the insertion rod 312 to be engaged. The first cleaning rollers 308 are synchronously rotated by the second slot 310 inside the cylindrical groove 309. Then, by controlling the rotation of the first sprocket 317, the first sprocket 317 drives the sleeve 315 to rotate. With the engagement of the limiting groove 316 inside the sleeve 315 and the second locking block 311, the first rotating rod 307 is driven to rotate, thereby driving the two first cleaning rollers 308 to rotate. The rotating first cleaning rollers 308 clean the debris generated during the grinding of the upper surface of the liquid crystal glass plate, and the debris is swept into the first collection box 304. The debris generated by the first grinding roller 206 during the grinding of the lower surface of the liquid crystal glass plate falls directly into the second collection box 401. With the operation of the two fans 402, the debris is adsorbed into the second collection box 401, thereby improving the debris cleaning effect.

[0032] Example 4, please refer to Figure 1-16This fourth embodiment is an improvement on the first embodiment, with the following modifications: the power assembly 5 includes a second motor 501 fixedly connected to the bottom of the operating table 101; a first upright plate 502 is fixedly connected to the bottom of the operating table 101; a bidirectional threaded rod 503 rotatably connected to the output end of the second motor 501 is fixedly connected to the first upright plate 502; a first bevel gear 504 is fixedly connected to the outer wall of the bidirectional threaded rod 503; two pushing members 6 adapted to one of the moving plates 106 are provided on the outer wall of the bidirectional threaded rod 503; each pushing member 6 includes a first circular plate 601 fixedly connected to the outer wall of the bidirectional threaded rod 503; a sliding rod 602 is symmetrically slidably connected through one side of the first circular plate 601; a second circular plate 603 slidably sleeved on the bidirectional threaded rod 503 is fixedly connected between the two sliding rods 602; and the first circular plate 601 and the second circular plate 603 are aligned with each other. The system includes a second spring 604 fixedly connected to the corresponding slide rod 602, baffles 605 fixedly connected to the ends of both slide rods 602, a bidirectional threaded rod 503 threadedly engaged with two movable plates 106, a transmission assembly 7 including a second upright plate 701 fixedly connected to the bottom of the operating table 101, a second rotating rod 702 rotatably connected through one side of the second upright plate 701, a second bevel gear 703 fixedly connected to one end of the second rotating rod 702 and meshing with the first bevel gear 504, and a second sprocket 704 fixedly connected to the other end of the second rotating rod 702, with a chain meshing between the second sprocket 704 and the first sprocket 317, and a PLC controller installed in the control box 107, with the PLC controller electrically connected to the first motor 215, cylinder 202, electromagnet 115, electric push rod 305, and second motor 501 via wires.

[0033] The operation process in this embodiment is as follows: Figure 1 , 14As shown in Figure 15, initially, the left movable plate 106 and the second circular plate 603 in the left pushing member 6 are in contact. At this time, the second spring 604 in the left pushing member 6 is in a compressed state, while the right second circular plate 603 is in a free state. By controlling the second motor 501 to drive the bidirectional threaded rod 503 to rotate, the bidirectional threaded rod 503 drives the two movable plates 106 to move to the right (initially, the left movable plate 106 and the bidirectional threaded rod 503 are disengaged from the threaded connection, but under the compression state of the left second circular plate 603 and the rotation of the bidirectional threaded rod 503, the left movable plate 106 quickly achieves threaded connection with the bidirectional threaded rod 503). After the left movable plate 106 moves to the right and abuts against the left first guide groove 103, the two electromagnets 1 on the left are controlled. When power is cut off, under the elastic force of the first spring 113, the clamping plate 112 moves away from the liquid crystal glass plate via the first L-shaped plate 111, so that the two clamping plates 112 on the left positioning plate 108 no longer clamp the liquid crystal glass plate. At the same time, the left moving plate 106 just disengages from the threaded connection on the bidirectional threaded rod 503, so that the left positioning plate 108 no longer moves to the right with the right positioning plate 108, while the two clamping plates 112 on the right positioning plate 108 are still in the clamping state, so that the two clamping plates 112 on the right can drag the liquid crystal glass plate to continue to move to the right, thereby avoiding the left positioning plate 108 from continuing to move to the right and interfering with the movement of the second grinding roller 210, thus ensuring that the liquid crystal glass plate is polished on both sides completely, thereby improving the polishing quality. During the rotation of the bidirectional threaded rod 503, the bidirectional threaded rod 503 drives the first bevel gear 504 to rotate, which in turn drives the second bevel gear 703 to rotate. This, in turn, drives the second sprocket 704 through the second rotating rod 702, which in turn drives the first sprocket 317 to rotate through the chain, thus providing power for the rotation of the first sprocket 317.
