Description

Technical Field

[0001] This application relates to the technical field of edge grinding equipment, and in particular to an edge grinding equipment for liquid crystal display screen processing. Background Technology

[0002] Liquid crystal displays (LCDs) are a display technology that uses electric current to stimulate liquid crystal molecules, creating dots, lines, and surfaces that, in conjunction with backlighting, form an image. In the manufacturing process of LCDs, the edge-grinding process is particularly important. This process plays a crucial role in improving the aesthetics, user comfort, and durability of the display.

[0003] Currently, common edge-grinding equipment includes a platform, a fixture, and a grinding head. The fixture is mounted on the platform, and during edge grinding, the LCD screen is fixed to the platform using the fixture. The grinding head is rotatably mounted on the platform, and can move closer to or further away from the LCD screen, and can move along the extension direction of one sidewall of the LCD screen. When the LCD screen is fixed to the platform, the grinding head is activated and moved until it contacts the sidewall of the LCD screen to be edged. Then, the grinding head is moved along the extension direction of the sidewall to be edged to grind the LCD screen.

[0004] However, during grinding, the only way to adapt to the angle and shape of the sidewall to be ground on the LCD screen is to change the shape of the grinding head, which is quite troublesome. Summary of the Invention

[0005] To facilitate grinding of different sidewalls of the edge to be ground during grinding, this application provides an edge grinding device for liquid crystal display screen processing.

[0006] This application provides a grinding equipment for processing liquid crystal displays, which adopts the following technical solution: A liquid crystal display screen processing edge grinding device includes a worktable, on which a mounting frame is provided; A rotating roller is disposed on the top of the worktable, the rotating roller extends in a vertical direction, and the rotating roller is arranged opposite to each other along the extension trajectory of one side edge of the worktable; The grinding belt is connected end to end and sleeved on the outer circumference of the rotating roller; A driving element, disposed on the mounting frame, drives one of the rotating rollers to rotate. A connecting roller is rotatably connected to the top of the worktable, and there are multiple connecting rollers evenly spaced between the rotating rollers. A connecting block is disposed on the outer peripheral sidewall of the connecting roller. A connecting groove is formed on the inner peripheral side of the grinding strip for the connecting block to slide. When the connecting block slides in the connecting groove, it restricts the grinding strip from moving away from the connecting roller. A bearing seat is slidably connected to the worktable, and the bearing seat is directly opposite the grinding belt between the rotating rollers. A clamping seat that cooperates with the bearing seat to clamp the workpiece is slidably connected to the mounting frame. The worktable is provided with a power component that drives the bearing seat and the clamping seat to move closer to or away from the grinding belt. A push block is provided between the grinding belt and the bearing seat. There are two sets of push blocks arranged symmetrically in the upper and lower parts. Each set of push blocks has multiple push blocks and corresponds one-to-one with the connecting roller. The outer peripheral sidewall of the grinding belt is symmetrically provided with circumferentially extending actuating strips, and the actuating block is formed with actuating groove for the actuating strips to slide. The mounting bracket is equipped with a control component, which controls the toggle block to move closer to or away from the support seat. At this time, the grinding strip on the side closer to the support seat forms a grinding cavity.

[0007] By adopting the above technical solution, during edge grinding, the shape of the edge grinding cavity can be adjusted by controlling the actuating block to approach the bearing seat according to the shape and number of the sidewalls to be ground on the workpiece. This helps the edge grinding belt adapt to the sidewalls to be ground on the workpiece, making it convenient to grind different sidewalls without changing the grinding part to adapt to the workpiece, thus greatly improving the edge grinding speed.

[0008] Optionally, the control assembly includes a control bolt, a control plate, and a control strip; The control bar is connected to the actuating block, and the control bar and the actuating block correspond one-to-one. The grinding strip is located between the upper and lower opposite control bars, and the control plate is connected to the upper and lower opposite control bars. The control bolt is threadedly connected to the mounting bracket, and the control bolt is rotatably connected to the control bar.

[0009] By adopting the above technical solution, the control component controls the actuating block through control bolts, control plate and control bar, so that the size and shape of the grinding cavity are adapted to the side wall of the workpiece to be ground.

[0010] Optionally, the control bolt slides up and down on the mounting bracket, and the mounting bracket is rotatably connected to lifting bolts that correspond one-to-one with the control plate, and the lifting bolts are rotatably connected to the control plate; The connecting roller includes a roller body and a roller sleeve. The roller sleeve is fitted on the outer periphery of the roller body, and the connecting block is disposed on the outer periphery of the roller sleeve. The roller body is provided with a limiting block, and the roller sleeve is formed with a limiting groove for the limiting block to slide up and down. The mounting bracket is threaded with a drive bolt, which is rotatably connected to and coaxially arranged with the roller sleeve.

[0011] By adopting the above technical solution, the lifting bolt is rotatably connected to the control board, enabling fine-tuning of the control board's up and down position. The connecting roller, through the design of its roller body and sleeve, allows for adjustment of the position of the sleeve and connecting block by rotating the drive bolt, facilitating adaptation to the position of the corresponding actuating block.

[0012] Optionally, the mounting bracket is provided with a first baffle, which is located between the grinding belt and the bearing seat; A second baffle is provided at the bottom of the first baffle, and the second baffle is located below the toggle block; An electrostatic generator is provided on the side of the first baffle and the second baffle facing away from the toggle block.

[0013] By adopting the above technical solution, the installation of the first and second baffles reduces the splashing of debris during grinding, protecting the working environment and worker safety. The electrostatic generator releases static electricity onto the first and second baffles, attracting tiny particles generated during grinding and improving the cleanliness of the working environment.

[0014] Optionally, the worktable is slidably connected to a movable block that can move closer to or further away from the grinding belt, and a rotating shaft is rotatably connected to the movable block, the rotating shaft being fixedly connected to the bearing seat; The movable block is provided with a rotating sleeve fitted on the outer periphery of the rotating shaft. A power coil spring is wound around the outer periphery of the rotating shaft. One end of the power coil spring is engaged with the rotating shaft, and the other end is engaged with the rotating sleeve. The movable block has a plug-in post that slides up and down, and the bottom of the support base is provided with a plurality of plug-in slots spaced apart along the circumference. The movable block is provided with a drive spring that drives the plug-in post to insert into the plug-in slot when aligned. The workbench is equipped with a power assembly. When the support seat moves away from the grinding belt, the power assembly drives the power coil spring to elastically contract. The worktable is provided with a push groove, the worktable is provided with a push column that slides in the push groove, the worktable is provided with a push spring that pushes the push column out of the push groove, and the push column is provided with a push surface that is inclined to the side away from the grinding belt; The movable block has a movable groove for the push column to slide in, and the outer peripheral sidewall of the plug-in column is provided with a drive block that slides up and down in the movable groove. The drive block is inclined to the side facing away from the grinding belt and has a drive surface. When the moving block moves away from the grinding belt, the pushing column slides past the driving block. At this time, the pushing column slides on the driving surface, pushing the driving block to slide downward, and causing the insertion column to disengage from the insertion slot. When the moving block moves toward the grinding belt, the driving block slides on the pushing surface, pushing the pushing column into the pushing groove. At this time, the driving block slides past the pushing column.

[0015] By adopting the above technical solution, the moving block achieves automatic rotation with the support seat through the setting of the rotating shaft and the power coil spring.

[0016] Optionally, the power assembly includes a power rack and a power gear; The power gear is disposed on the outer periphery of the rotating shaft and rotatably connected to the moving block. The power rack is disposed on the worktable and is slidably connected to the moving block. The power rack meshes with the power gear.

[0017] By adopting the above technical solution, the power component drives the rotating sleeve to rotate through the interaction of the power rack and the power gear, so that the power coil spring enters the elastic storage state.

[0018] Optionally, the power component is a power cylinder, which is disposed on the worktable, and the piston rod of the power cylinder is connected to the side of the moving block away from the grinding belt.

[0019] By adopting the above technical solution, the power component uses a power cylinder, and the moving block moves closer to or further away from the grinding belt through the extension and retraction movement of the power cylinder.

[0020] Optionally, the driving component is a drive motor, which is fixed to the mounting frame, and the output shaft of the drive motor is connected to and coaxially arranged with one of the rotating rollers.

[0021] By adopting the above technical solution, the driving component is a drive motor, which is fixed to the mounting frame. The output shaft is connected to one of the rotating rollers and is coaxially arranged. When started, it drives the rotating roller and the grinding belt to rotate.

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses an edge grinding device for processing liquid crystal displays.

[0027] See Figure 1 The edge grinding equipment includes a worktable 1, on which a mounting frame 11 is fixedly installed. The mounting frame 11 includes multiple horizontal columns and vertical columns that are fixedly connected to each other.

[0028] The edge grinding equipment also includes a rotating roller 2, a grinding belt 3, and a driving component. The rotating roller 2 is rotatably connected to the top of the worktable 1, and its central axis extends vertically. The rotating roller 2 is located on the side of the vertical column of the mounting frame 11 away from the edge of the worktable 1. There are two rotating rollers 2 arranged symmetrically. The two rotating rollers 2 are spaced apart and opposite each other along the trajectory of one side edge of the worktable 1, and the distance between the two rotating rollers 2 is greater than the length of the workpiece. The grinding belt 3 is connected end to end and sleeved on the outer periphery of the opposite rotating roller 2. When the rotating roller 2 rotates, it drives the grinding belt 3 to rotate cyclically.

[0029] The driving component is a drive motor 12, which is fixedly connected to the mounting bracket 11 and positioned above the grinding belt 3. The output shaft of the drive motor 12 is fixedly connected to one of the rotating rollers 2 and is coaxially arranged. When the drive motor 12 starts, it drives the rotating roller 2 to rotate, causing the grinding belt 3 to enter a rotating state. See Figure 1 and Figure 2 The edge grinding equipment also includes a connecting roller 4 and a connecting block 31. The connecting roller 4 is fixedly connected to the top of the worktable 1 and is located between the relatively rotating rollers 2. There are multiple connecting rollers 4 and they are evenly spaced. In this embodiment, there are three connecting rollers 4.

[0030] The vertical cross-section of the connecting block 31 is a "T" shape. The connecting block 31 is fixedly connected to the outer peripheral sidewall of the connecting roller 4. A connecting groove 41 is formed on the inner peripheral sidewall of the grinding belt 3. The connecting groove 41 extends circumferentially, and its vertical cross-section is a "T" shape. The connecting block 31 is slidably connected within the connecting groove 41. At this time, the connecting block 31 restricts the grinding belt 3 from moving away from the connecting roller 4.

[0031] See Figure 3 and Figure 4 The worktable 1 is provided with a sliding groove 19, the extension direction of which is perpendicular to the connection line between the relatively rotating rollers 2. A movable block 18 is provided on the worktable 1, which is slidably connected in the sliding groove 19. A rotating shaft 51 is rotatably connected to the movable block 18. A bearing seat 5 is fixedly connected to the top of the rotating shaft 51. The bearing seat 5 is located on the vertical side of the grinding belt 3 away from the mounting frame 11, and the bearing seat 5 is directly opposite the grinding belt 3 between the relatively rotating rollers 2.

[0032] A length-adjustable clamping column is slidably connected to the mounting frame 11. The clamping column is located directly above the sliding groove 19, and its sliding trajectory is parallel to that of the moving block 18. A clamping seat 13 is provided at the bottom of the clamping column, located directly above the support seat 5. During installation, the workpiece to be edged is placed on top of the support seat 5, and then the length of the clamping column is adjusted so that the support seat 5 and the clamping seat 13 cooperate to clamp and fix the workpiece. Then, the edge of the workpiece can be edged using the edge grinding belt 3. In this embodiment, the clamping column includes a column body and a column sleeve. The top of the column sleeve is slidably connected to the mounting frame 11, and the column body slides up and down on the column sleeve. A fixing bolt is threaded onto the column sleeve, and the adjusted fixing column is fixed by the fixing bolt. In other embodiments, a fixing column can be slidably inserted through the column sleeve, and a fixing groove is provided on the column body. The length of the clamping column is fixed by the fixing column and the fixing bolt.

[0033] See Figure 4 and Figure 5 The worktable 1 is equipped with a power component, namely a power cylinder 14, which is fixed inside the worktable 1. The piston rod of the power cylinder 14 is fixedly connected to the side wall of the moving block 18 away from the grinding belt 3. When the power cylinder 14 is activated, it drives the bearing seat 5 to move closer to or away from the grinding belt 3. At this time, the bearing seat 5 cooperates with the clamping seat 13 to move the workpiece closer to or away from the grinding belt 3, facilitating the grinding of the workpiece and the replacement of the workpiece. Multiple control buttons are installed and fixed on the worktable 1, corresponding to the drive motor 12 and the power cylinder 14. In use, the drive motor 12 is controlled by the control buttons (the drive motor 12 is located on the side wall of the moving block 18 away from the grinding belt 3). Figure 3 (Winning the bid) and the opening and closing of the power cylinder 14.

[0034] See Figure 2 A toggle block 32 is provided between the grinding belt 3 and the bearing seat 5. There are two sets of toggle blocks 32, which are arranged symmetrically from top to bottom. Each set of toggle blocks 32 has multiple blocks, which correspond one-to-one with the connecting roller 4. The two sets of toggle blocks 32 are located at the top and bottom edges of the grinding belt 3, respectively. Aggle strips 33 are symmetrically arranged on the outer peripheral sidewall of the grinding belt 3. The toggle strips 33 extend circumferentially, and the ends of the toggle strips 33 are connected, with the vertical cross-section forming a "T" shape.

[0035] See Figure 6 and Figure 7 The actuating block 32 has an actuating groove 321 on the side facing the grinding belt 3. The groove of the actuating groove 321 is in the shape of a "T". The actuating strip 33 is slidably connected in the actuating groove 321.

[0036] Mounting bracket 11 is equipped with a control component 6, which controls the toggle block 32 to move closer to or further away from the support seat 5. When the toggle block 32 moves closer to the support seat 5 (the support seat 5 is in...), the toggle block 32 moves closer to the support seat 5. Figure 4When the marked side moves, the actuating block 32 drives the top and bottom edges of the grinding belt 3 between the relatively rotating rollers 2 to flip, so that the grinding belt 3 between the relatively rotating rollers 2 forms a grinding cavity, which can increase the grinding area of ​​the grinding belt 3, or grind the workpiece when the grinding surface of the workpiece is an arc structure. This is beneficial for the grinding belt 3 to grind multiple grinding surfaces of the workpiece and adapt to the shape of the grinding surface of the workpiece.

[0037] The control assembly 6 includes a control bolt 61, a control plate 62, and a control strip 63. The control strip 63 is fixedly connected to the actuating block 32 and has a "7" shape. There are multiple control strips 63, each corresponding to one of the actuating blocks 32. The grinding edge strip 3 is located between the upper and lower opposing control strips 63. There are multiple control plates 62, each corresponding to two upper and lower control strips 63. The two ends of the control plate 62 are fixedly connected to the side of the upper and lower opposing control strips 63 away from the actuating block 32, and the control plate 62 has a "7" shape.

[0038] The control bolt 61 is threaded onto the vertical column of the mounting bracket 11, and its end is rotatably connected to the top of the control strip 63. In use, rotating the control bolt 61 moves the control plate 62 closer to or further away from the support seat 5 (the support seat 5 is located in...). Figure 4 (If the bid is successful), the control bar 63 will cause the toggle block 32 to move closer to or away from the support seat 5.

[0039] The control bolt 61 slides up and down on the mounting bracket 11. The mounting bracket 11 is rotatably connected to the lifting bolt 621, which corresponds one-to-one with the control plate 62. The lifting bolt 621 is rotatably connected to the control plate 62. In use, rotating the lifting bolt 621 can drive the control plate 62 to move up and down.

[0040] See Figure 2 The connecting roller 4 includes a roller body 42 and a roller sleeve 43. The roller body 42 is fixedly connected to the worktable 1, and the roller sleeve 43 is fitted onto the outer periphery of the roller body 42. A connecting block 31 is fixedly connected to the outer periphery of the roller sleeve 43. A limiting block 421 is fixedly connected to the outer periphery of the roller body 42, and the roller sleeve 43 has a limiting groove 431 extending in the vertical direction. The limiting block 421 slides up and down in the limiting groove 431. In use, the roller sleeve 43 can slide up and down on the roller body 42, and the roller body 42 can be restricted to rotate by the limiting block 421.

[0041] Mounting bracket 11 is threadedly connected to drive bolt 44, which is rotatably connected to and coaxially arranged with the top end face of roller sleeve 43. Rotating drive bolt 44 can drive roller sleeve 43 to move up and down. In use, the vertical height of roller sleeve 43 is adjusted by drive bolt 44, and the vertical height of toggle block 32 is adjusted by lifting bolt 621, so that the extension trajectory of grinding cavity adapts to the extension trajectory of workpiece edge sidewall.

[0042] See Figure 1 and Figure 2 A first baffle 15 is fixedly connected to the mounting bracket 11. The first baffle 15 is located between the grinding belt 3 and the support seat 5, and is close to one of the rotating rollers 2. The first baffle 15 is slidably connected to the grinding belt 3. In use, when the grinding belt 3 grinds the workpiece, the powder generated by grinding follows the movement of the grinding belt 3. Then, the powder impacts the first baffle 15, which restricts the powder. A second baffle 16 is fixedly connected to the bottom of the first baffle 15. The second baffle 16 is located below the actuating block 32 and is used to catch the falling powder.

[0043] An electrostatic generator 17 is installed and fixed on the side of the first baffle 15 and the second baffle 16 facing away from the actuating block 32. When in use, the electrostatic generator 17 generates an electrostatic adsorption field at the position of the first baffle 15 and the second baffle 16 near the actuating block 32, so that the powder generated by the grinding belt 3 is adsorbed on the first baffle 15 and the second baffle 16, reducing the possibility of powder scattering.

[0044] See Figure 4 A rotating sleeve 52 is rotatably connected inside the movable block 18. The rotating sleeve 52 is sleeved on the outer periphery of the rotating shaft 51 and is coaxially arranged. The inner diameter of the rotating sleeve 52 is larger than the outer diameter of the rotating shaft 51. A power coil spring 53 is wound around the outer periphery of the rotating shaft 51. One end of the power coil spring 53 is engaged with the outer wall of the rotating shaft 51, and the other end is engaged with the inner wall of the rotating sleeve 52.

[0045] See Figure 3 and Figure 4 The movable block 18 has a sliding insertion post 181, and the line connecting the insertion post 181 and the rotating shaft 51 is parallel to the line connecting the rotating roller 2. The bottom of the support seat 5 has multiple insertion slots 54, spaced 90 degrees apart circumferentially. A drive spring 182 is installed inside the movable block 18. When the rotating shaft 51 rotates, it drives the support seat 5 to rotate until the insertion post 181 aligns with the insertion slot 54. Then, the drive spring 182 drives the insertion post 181 to insert into the insertion slot 54, restricting the rotation of the support seat 5. At this time, one side of the workpiece to be ground faces the grinding belt 3.

[0046] See Figure 7 and Figure 8 The workbench 1 is equipped with a power unit 7 and a support base 5 (the support base 5 is located in...). Figure 4When the bearing seat 5 moves away from the grinding belt 3, the power assembly 7 drives the rotating sleeve 52 to rotate, causing the power coil spring 53 to elastically contract. The power assembly 7 includes a power rack 71 and a power gear 72. The power gear 72 is fixedly connected to the outer periphery of the rotating shaft 51 and rotatably connected to the moving block 18. The power rack 71 is fixedly connected to the vertical groove wall on one side of the sliding groove 19. The power rack 71 is slidably connected to the moving block 18, and the power rack 71 meshes with the power gear 72. When the bearing seat 5 moves away from the grinding belt 3, the power rack 71 and the power gear 72 cooperate to drive the rotating sleeve 52 to rotate, causing the power coil spring 53 to elastically contract.

[0047] A pushing groove 191 extending away from the sliding groove 19 is formed on the vertical side wall of the sliding groove 19 away from the power rack 71. The worktable 1 is provided with a long, rectangular pushing column 192, which slides within the pushing groove 191. The pushing column 192 has a pushing surface 1921 inclined on the side facing away from the grinding belt 3. The worktable 1 is provided with a pushing spring 193, which is installed within the pushing groove 191. One end of the pushing spring 193 abuts against the pushing column 192, and the other end abuts against the side wall of the pushing groove 191 away from the groove opening. When the pushing spring 193 is released elastically, it pushes the pushing column 192 out of the pushing groove 191.

[0048] A moving groove 183 is formed on the side of the moving block 18 facing away from the power rack 71. The moving groove 183 extends horizontally. When the moving block 18 slides in the sliding groove 19 away from the grinding belt 3, the pushing column 192 can slide through the moving groove 183. A driving block 1811 is fixedly connected to the outer peripheral side wall of the insertion column 181. The driving block 1811 slides up and down in the moving groove 183. The driving block 1811 has a driving surface 1812 formed at an angle on the side facing away from the grinding belt 3.

[0049] When the moving block 18 moves away from the grinding belt 3 and closer to the push column 192, the power coil spring 53 enters the retracted state; then, when the moving block 18 slides past the push column 192, the push column 192 slides past the drive block 1811. At this time, the push column 192 slides on the drive surface 1812, pushing the drive block 1811 to slide downward, causing the insertion column 181 to slide downward and squeeze the drive spring 182, so that the insertion column 181 disengages from the insertion slot 54. At this time, the power coil spring 53 is released elastically, driving the rotating shaft 51 to enter the rotation state, driving the workpiece to rotate; when the push column 192 passes the drive block 1811, the drive spring 182 is released elastically, pushing the insertion column 181 to abut against the bearing seat 5 (the bearing seat 5 is in Figure 4 At the bottom of the workpiece (marked out), when the bearing seat 5 rotates to the next adjacent insertion slot 54 aligned with the insertion post 181, the drive spring 182 drives the insertion post 181 to insert into the insertion slot 54, keeping the side wall of the next adjacent edge to be ground facing the grinding strip 3.

[0050] When the moving block 18 passes the push post 192, the moving block 18 stops moving away from the grinding belt 3; then the moving block 18 is controlled to move towards the grinding belt 3, at which point the moving block 18 passes the push post 192 again. Then, when the driving block 1811 passes the push post 192 towards the grinding belt 3, the driving block 1811 slides on the push surface 1921, pushing the push post 192 into the push groove 191, pushing the spring 193 into a compressed state, so that the driving block 1811 can slide past the push post 192. Then the bearing seat 5 (the bearing seat 5 is in Figure 4 When the workpiece approaches the grinding belt 3 and is subjected to grinding, the power coil spring 53 stretches in the opposite direction. Then, when the bearing seat 5 drives the workpiece that has completed grinding away from the grinding belt 3, the power coil spring 53 first elastically recovers and then elastically contracts, accumulating the power to drive the rotating shaft 51 to rotate.

[0051] The implementation principle of a liquid crystal display screen edge grinding device according to an embodiment of this application is as follows: During edge grinding, based on the number of sidewalls to be ground and their extension trajectory, the number of grinding surfaces of the grinding belt 3 on the workpiece is adjusted by controlling the actuating block 32 to move closer to the bearing seat 5. The extension trajectory of the grinding cavity is adjusted by controlling the vertical height of the actuating block 32 and the vertical height of the roller sleeve 43, so that the grinding cavity adapts to the workpiece to be ground. Then, the electrostatic generator 17 is started, and the drive motor 12 and the power cylinder 14 are started by controlling the control button, so that the grinding belt 3 can perform edge grinding with the workpiece.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
