A polishing mechanism is provided on the operating table. A clamping mechanism for fixing the position of the light guide plate is provided on one side of the operating table. An adjustment mechanism for moving the light guide plate is also provided on the operating table. This utility model, through its cleaning mechanism, facilitates the cleaning of debris on the surface of the light guide plate, improving the operator's work efficiency.

[0003] Based on the above, the inventors have discovered the following problems: the above-mentioned device can effectively clean debris from the surface of the light guide plate, but manual loading is still required. During long-term labor, operators may experience excessive labor consumption and unstable operation, which may affect the production quality of the light guide plate. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a light guide plate polishing machine with a positioning and feeding structure, comprising a base and a conveyor belt, wherein the base is provided with a conveyor belt on one side, a feeding component is provided at the upper end of the conveyor belt, limiting components are provided on both sides of the conveyor belt, an operating table is provided on the side of the conveyor belt away from the base, a polishing mechanism is provided on one side of the operating table, a support seat is provided on the other side of the operating table, and a fixing mechanism is provided on the support seat.

[0005] Furthermore, the feeding assembly includes a support frame located on the side of the conveyor belt, with a placement box at the upper end of the support frame. A hydraulic telescopic rod is provided at the upper end of the base, with the output end of the hydraulic telescopic rod facing the conveyor belt. A push plate is provided at the output end of the hydraulic telescopic rod. A groove is provided on one side of the hydraulic telescopic rod and at the upper end of the base, with a movable block movably connected in the groove. The side of the push plate is connected to the side of the movable block.

[0006] Furthermore, movable grooves are provided on both sides of the lower end of the inner wall of the placement box, and a rotating shaft is provided in each movable groove. A clamping plate is provided on the rotating shaft and located in the movable groove. One end of a pair of rotating shafts passes through the movable groove and is respectively provided with gear one and gear two. Gear one and gear two mesh with each other, and gear two and gear one are movably connected to the side of the support frame. One of the rotating shafts of the pair extends out of the placement box and is provided with a transmission plate. The transmission plate is adapted to the moving block.

[0007] Furthermore, the limiting component includes a connecting plate, a pair of connecting plates symmetrically arranged on both sides of the conveyor belt, and a rotating bolt threadedly connected to the connecting plate, the rotating bolt being movably connected to the limiting plate toward the upper end of the conveyor belt.

[0008] Furthermore, the moving block is provided with a trapezoidal groove, the bottom height of which is less than the bottom height of the transmission plate, and the top height of which is greater than the bottom height of the transmission plate.

[0009] Furthermore, a roller is movably provided at the lower end of the transmission plate, and a rubber layer is provided on the opposite side of the pair of clamping plates.

[0010] Furthermore, the pair of limiting plates are funnel-shaped, and the distance between the pair of limiting plates facing the hydraulic telescopic rod is greater than the distance between them facing the operating table.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the light guide plate polishing machine with a positioning and feeding structure is reasonable and has the following advantages: By coordinating the push plate, moving block, and transmission plate, the light guide plate on the conveyor belt can be pushed while simultaneously fixing and separating the light guide plate at the bottom of the placement box from the one on the conveyor belt. When the light guide plate at the top of the conveyor belt moves along the belt, the upper end of the light guide plate on the conveyor belt will not rub against the lower end of the light guide plate at the bottom of the placement box, thus ensuring the integrity of the light guide plate surface. When the hydraulic telescopic rod is activated in the reverse direction, the push plate, transmission plate, and moving block all return to their initial positions, thereby releasing the clamping plates from fixing the light guide plate. This allows the light guide plate inside the placement box to fall onto the conveyor belt under gravity, preparing for the next feeding cycle. In summary, this achieves continuous and stable [feeding]. The feeding operation effectively solves the problems of labor consumption and operational instability that may occur with traditional manual feeding, and does not damage the surface structure of the light guide plate. Compared with traditional manual conveying, it can greatly reduce labor consumption. Moreover, through the cooperation of the limiting plate and the conveyor roller belt, the light guide plate can be gradually moved to the operating table, and its position can be corrected to the center of the operating table, ensuring the accuracy of subsequent polishing operations. When rotating the rotating bolt, the limiting plate can be pushed towards the upper end of the conveyor roller belt, thereby adjusting the distance between a pair of limiting plates, and then guiding light guide plates of different sizes, thus expanding the applicability of this device.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 The present invention provides a technical solution as follows: Example: In this embodiment, a light guide plate polishing machine with a positioning and feeding structure includes a base 1 and a conveyor belt 5. The base 1 has a conveyor belt 5 on one side, a feeding component on the upper end of the conveyor belt 5, and limiting components on both sides of the conveyor belt 5. An operating table 8 is provided on the side of the conveyor belt 5 away from the base 1. A polishing mechanism 3 is provided on one side of the operating table 8, and a support seat 2 is provided on the other side of the operating table 8. A fixing mechanism 6 is provided on the support seat 2.

[0016] The feeding assembly includes a support frame 7 located on the side of the conveyor belt 5, and a placement box 4 is provided on the upper end of the support frame 7. A hydraulic telescopic rod 13 is provided on the upper end of the base 1, with the output end of the hydraulic telescopic rod 13 facing the conveyor belt 5. A push plate 17 is provided on the output end of the hydraulic telescopic rod 13. A sliding groove 14 is provided on one side of the hydraulic telescopic rod 13 and on the upper end of the base 1. A movable block 12 is movably connected in the sliding groove 14. The side of the push plate 17 is connected to the side of the movable block 12.

[0017] The lower two sides of the inner wall of the placement box 4 are provided with movable grooves 18. Each movable groove 18 is provided with a rotating shaft 20. A clamping plate 19 is provided on the rotating shaft 20 and located in the movable groove 18. One end of each pair of rotating shafts 20 passes through the movable groove 18 and is provided with a gear 15 and a gear 26 respectively. The gear 15 and gear 26 mesh with each other, and both gear 26 and gear 15 are movably connected to the side of the support frame 7. One of the rotating shafts 20 extends out of the placement box 4 and is provided with a transmission plate 21. The transmission plate 21 is adapted to the moving block 12. The placement box 4 is filled with several light guide plates. At this time, the light guide plate at the lower end of the placement box 4 is located above the conveyor belt 5. When feeding is required, the hydraulic telescopic rod 13 is activated, which drives the push plate 17 to move towards the guide plate between the conveyor belt 5 and the placement box 4. At the same time, the movement of the push plate 17 drives the moving block 12 to move in the same direction in the slide 14. When the moving block 12 contacts the transmission plate 21, the trapezoidal groove design in the moving block 12 allows the transmission plate 21 to rotate around the axis of the rotating shaft 20 to a certain angle, and can maintain the rotation angle of the transmission plate 21 for a period of time. At this time, the rotation of the transmission plate 21 drives the rotating shaft 20 to rotate, thereby driving the gear 15 to rotate in the same direction and the gear 2 16 to rotate in the opposite direction, thereby driving the pair of clamping plates 19 to rotate closer to each other, which can push the light guide plate at the bottom of the placement box 4 into the light guide plate. The light guide plate at the bottom of the placement box 4 is slightly moved upwards, causing it to separate slightly from the light guide plate on the conveyor belt 5. As the push plate 17 continues to move, it can push the light guide plate on the conveyor belt 5 to the position of the limiting plate 10. Since the light guide plate at the bottom of the placement box 4 is separated from the light guide plate at the top of the conveyor belt 5, when the light guide plate at the top of the conveyor belt 5 moves on the conveyor belt 5, the upper end of the light guide plate on the conveyor belt 5 will not rub against the lower end of the light guide plate at the bottom of the placement box 4, thus ensuring the integrity of the light guide plate surface. When the hydraulic telescopic rod 13 is started in reverse, it drives the push plate 17, the transmission plate 21 and the moving block 12 to return to their initial positions, thereby releasing the clamping plates 19 from fixing the light guide plate, allowing the light guide plate in the placement box 4 to fall onto the conveyor belt 5 by gravity, thus preparing for the next feeding.

[0018] The limiting component includes a connecting plate 9. A pair of connecting plates (9) are symmetrically arranged on both sides of the conveyor belt 5. A rotating bolt 11 is threaded onto the connecting plate 9. The rotating bolt 11 is movably connected to the upper end of the conveyor belt 5 via a limiting plate 10. Through the design of the connecting plate 9 and the rotating bolt 11, rotating the rotating bolt 11 can push the limiting plate 10 to move towards the upper end of the conveyor roller belt 5, thereby adjusting the distance between a pair of limiting plates 10, and then guiding light guide plates of different sizes to ensure that the light guide plates can move to the middle position of the operating table 8. Combined with the fixing mechanism 6, the light guide plates can be fixed in the middle position of the operating table 8, thereby preventing the light guide plates from shifting. Combined with the design of the polishing mechanism 3, the light guide plates can be accurately polished.

[0019] The movable block 12 is provided with a trapezoidal groove, the bottom height of the trapezoidal groove is less than the bottom height of the transmission plate 21, and the top height of the trapezoidal groove is greater than the bottom height of the transmission plate 21. With the design of the trapezoidal groove, when the transmission plate 21 is located on the inclined surface of the trapezoidal groove, it can smoothly push the transmission plate 21 to rotate around the axis of the rotating shaft 20. With the design of a rubber layer on the opposite side of the clamping plate 19, the clamping plate 19 can avoid scratching the side of the light guide plate, thus ensuring the structural integrity of the light guide plate.

[0020] The transmission plate 21 is movably provided with a roller 22 at its lower end, and a rubber layer is provided on one side of the pair of clamping plates 19 facing each other. With the design of roller 22 at the lower end of transmission plate 21, there will be no jamming when transmission plate 21 moves back and forth in the trapezoidal groove in moving block 12, ensuring the normal operation of transmission plate 21.

[0021] Among them, the pair of limiting plates 10 are funnel-shaped, and the distance between the pair of limiting plates 10 on the side facing the hydraulic telescopic rod 13 is greater than the distance on the side facing the operating table 8. By using a pair of limit plates 10 in a funnel shape, combined with the operation of the conveyor belt 5, the light guide plate can be gradually moved to the operating table 8, and the position of the light guide plate can be corrected to the middle position of the operating table 8, thus ensuring the accuracy of the subsequent polishing operation of the light guide plate.

[0022] Working principle: During use, several light guide plates are placed inside the placement box 4. At this time, the light guide plate at the lower end of the placement box 4 is located above the conveyor belt 5. When feeding is required, the hydraulic telescopic rod 13 is activated, which drives the push plate 17 to move towards the guide plate between the conveyor belt 5 and the placement box 4. At the same time, the movement of the push plate 17 drives the moving block 12 to move in the same direction within the slide groove 14. When the moving block 12 contacts the transmission plate 21, the trapezoidal groove design within the moving block 12 allows the transmission plate 21 to rotate to a certain angle around the axis of the rotating shaft 20. To maintain the rotation angle of the transmission plate 21 for a certain period of time, the rotation of the transmission plate 21 drives the rotation shaft 20 to rotate, thereby driving gear 15 to rotate in the same direction and gear 16 to rotate in the opposite direction, thereby driving a pair of clamping plates 19 to rotate closer to each other. This can fix and slightly move the light guide plate at the bottom of the placement box 4, so that the light guide plate at the bottom of the placement box 4 and the light guide plate on the conveyor roller belt 5 are slightly separated. As the push plate 17 continues to move, the push plate 17 can push the light guide plate on the conveyor roller belt 5 to the position of the limit plate 10, and then the conveyor roller belt 5 The light guide plate, in conjunction with the limiting plate 10, can be moved onto the operating table 8 for the next polishing operation. Since the light guide plate at the bottom of the placement box 4 is separated from the light guide plate at the top of the conveyor belt 5, when the light guide plate at the top of the conveyor belt 5 moves on the conveyor belt 5, the upper end of the light guide plate on the conveyor belt 5 will not rub against the lower end of the light guide plate at the bottom of the placement box 4, thus ensuring the integrity of the light guide plate surface. When the hydraulic telescopic rod 13 is activated in the reverse direction, it drives the push plate 17, the transmission plate 21, and the moving block 12 to return to their initial positions, thereby releasing the clamping plates 19 from fixing the light guide plate, allowing the light guide plate in the placement box 4 to fall onto the conveyor belt 5 under gravity, thus preparing for the next loading. By repeating the above operation, the light guide plate can be continuously conveyed to the top of the operating table 8.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
