Description

Technical Field

[0001] This invention belongs to the field of laser cutting machine technology, specifically a laser cutting device for light guide plates. Background Technology

[0002] A light guide plate is an optical component used to efficiently convert point or line light sources into uniform surface light sources. During manufacturing, it is often necessary to use laser cutting to cut multiple circular plates from a single light guide plate for use in various circular optical devices.

[0003] Patent CN211465195U discloses a laser cutting machine for a light guide plate, including a machine body, a cutting mechanism, and a fixing mechanism. During laser cutting, the light guide plate reflects the laser light, which can cause serious eye damage to workers. The installation of a light-shielding device blocks the laser light from reflecting into the workers' eyes, improving the safety of the working environment. The light-shielding plate is made of one-way transparent glass, ensuring that workers can observe the cutting effect of the cutting head on the light guide plate and the operating status of the device. The clamping device firmly fixes the light guide plate under the cutting head, allowing for easy rotation of both sides of the light guide plate without the need for other devices underneath. The structure is simple, flexible, and easy to operate. The gasket is made of sponge material, preventing scratches from mechanical friction during fixing and providing protection. This device offers a safe working environment, simple structure, and convenient operation.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: When multiple circular plates are laser-cut from the light guide plate, a collection box is used to collect the cut circular plates. The circular plates then pile up haphazardly in the collection box.

[0005] However, in some cases, after collecting a certain number of discs, it is necessary to divide a specified number of discs into multiple containers based on the total number of discs for subsequent transportation and retrieval. Because the discs are piled up haphazardly in the collection box, it is difficult to remove the specified number of discs at once by simply dumping them, thus affecting the smooth progress of the dispensing process.

[0010] Preferably, a threaded rod is threadedly connected to one side of the slider, and both ends of the threaded rod are rotatably connected to the mounting bracket.

[0011] Preferably, the support frame is provided with a light guide plate positioning assembly; The light guide plate positioning assembly includes two cylinders, which are symmetrically fixedly connected to two support frames. A positioning plate is fixedly connected to the piston end of each cylinder.

[0012] Preferably, the body is provided with an adjustment component for adjusting the orientation of the mounting bracket; The adjustment assembly includes a lead screw guide module three located on one side of the bottom of the inner cavity of the machine body. The movable end of the lead screw guide module three is fixedly connected to a movable seat one. A lead screw guide module four is provided on one side of the upper surface of the movable seat one. The movable end of the lead screw guide module four is fixedly connected to the bottom of the movable seat two. A motor one is fixedly connected to one side of the top of the movable seat two. The output end of the motor one is fixedly connected to one side of the mounting bracket.

[0013] Preferably, it also includes an anti-crushing component; The anti-pinch component includes multiple blocks that are longitudinally distributed and laterally slidably inserted through the front and rear limit plates. Each of the front and rear limit plates is fixedly connected to a sliding groove plate. A pressing rod for pressing the block is slidably connected to the sliding groove of the sliding groove plate. A winding roller is rotatably connected to the bottom of each of the front and rear limit plates.

[0016] The beneficial effects of this invention are as follows: 1. The laser cutting equipment for light guide plates described in this invention utilizes a follow-up collection auxiliary component. Each time a circular plate is cut, it is placed within a enclosure composed of four limiting plates, resulting in multiple circular plates being neatly stacked. Subsequently, according to packaging requirements, a specified number of circular plates can be dropped out through the enclosure and packaged into different containers, facilitating subsequent unified transfer and retrieval of the circular plates.

[0017] 2. The laser cutting equipment for light guide plates described in this invention utilizes an anti-crushing component. When multiple circular plates are placed within a enclosure, multiple blocks support and separate the plates, preventing breakage due to pressure from upper plates on lower plates and thus ensuring plate quality. Furthermore, when collecting the plates, the pressing rod resets, causing the blocks to also reset, resulting in the plates falling sequentially.

[0018] 3. The laser cutting equipment for light guide plates described in this invention utilizes an auxiliary release component. When the cut circular plate is stuck and cannot fall normally, a suction cup can be used to hold the circular plate and place it stably on two support blocks. This avoids the situation where the cut circular plate gets stuck due to friction and cannot fall normally, thus affecting the normal collection of the circular plate. Furthermore, compared to directly pushing the circular plate down, this method uses negative pressure suction to push the circular plate down and stably place it on the two support blocks, avoiding the situation where the circular plate bends or breaks due to the simultaneous support force and pushing force of the support blocks when directly pushing it.

[0023] Please refer to Figures 1-10 The present invention provides a technical solution: a laser cutting device for light guide plates, including a body 1, a laser cutting head 37, a displacement component for driving the laser cutting head 37 inside the body 1, and a follow-up collection auxiliary component for collecting the cut circular plates inside the body 1. The follow-up collection auxiliary component includes a second movable base 11. The upper ends of both sides of the second movable base 11 are rotatably connected to a mounting frame 13.

[0024] In this embodiment, as Figure 3 , Figure 4 , Figure 6As shown, the displacement assembly includes two support frames 2 fixedly connected inside the body 1. The top of the two support frames 2 is provided with a second screw guide module 6. The moving end of the second screw guide module 6 is fixedly connected to a crossbeam 3.

The piston end of the fifth cylinder 39 is fixedly connected to one end of the laser cutting head 37.

[0025] A cylinder 28 is fixedly connected to the center of the bottom of the mounting bracket 13. A connecting block 29 is fixedly connected to the piston end of the cylinder 28. Multiple connecting rods 30 are rotatably connected to the connecting block 29 along the circumferential direction, and the end of each connecting rod 30 is rotatably connected to the bottom of a transverse block 31.

[0026] A threaded rod 16 is threadedly connected to one side of the slider 17. Both ends of the threaded rod 16 are rotatably connected to the mounting bracket 13. Motors 14 are fixedly connected to both sides of the bottom of the mounting bracket 13. The output end of the motors 14 is fixedly connected to one end of the threaded rod 16.

[0027] The support frame 2 is equipped with a light guide plate positioning assembly; The light guide plate positioning assembly includes two cylinders 7, which are symmetrically fixedly connected to two support frames 2. A positioning plate 8 is fixedly connected to the piston end of each cylinder 7.

[0028] The main body 1 is equipped with an adjustment component for adjusting the position of the mounting bracket 13; The adjustment assembly includes a lead screw guide module 3 9 located on one side of the bottom of the inner cavity of the body 1. The movable end of the lead screw guide module 3 9 is fixedly connected to a movable seat 1 4. A lead screw guide module 4 10 is provided on one side of the upper surface of the movable seat 1 4. The movable end of the lead screw guide module 4 10 is fixedly connected to the bottom of the movable seat 2 11. A motor 12 is fixedly connected to one side of the top of the movable seat 2 11. The output end of the motor 12 is fixedly connected to one side of the mounting bracket 13.

[0029] Specifically, in existing technologies, when multiple circular plates are laser-cut from a light guide plate, a collection box is used to collect the cut circular plates. However, the circular plates tend to pile up haphazardly in the collection box.

[0030] However, in some cases, after collecting a certain number of discs, it is necessary to divide a specified number of discs into multiple containers based on the total number of discs for subsequent transportation and retrieval. Because the discs are piled up haphazardly in the collection box, it is difficult to remove the specified number of discs at once by simply dumping them, thus affecting the smooth progress of the dispensing process.

[0031] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: This method is only used to collect multiple circular plates of the same size at a time. First, the light guide plate to be cut is placed between two positioning plates 8. Then, the cylinders 7 on both sides are used to move the two positioning plates 8 so that the two positioning plates 8 are respectively attached to the two side edges of the light guide plate, thus clamping and fixing the light guide plate.

[0032] Subsequently, by adjusting the position of the laser cutting head 37 in the x, y, and z axes using the lead screw guide module 1 5, lead screw guide module 2 6, and cylinder 5 39, the laser cutting head 37 can be used to cut the light guide plate.

[0033] Furthermore, during the cutting process, the position of the moving seat 2 11 is adjusted using the lead screw guide module 3 9 and the lead screw guide module 4 10, so that the axis of the bottom disc of the moving seat 2 11 coincides with the axis of the disc to be cut. At this time, the two support blocks 38 are at their highest point, and when the disc is cut off, it will fall on the two support blocks 38. Moreover, according to the diameter of the disc, the connecting block 29 is moved up and down by the cylinder 3 28, and multiple connecting rods 30 can simultaneously drive multiple transverse blocks 31 to slide, thereby adjusting the size of the enclosure composed of four limiting plates 19 and matching this size with the diameter of the disc.

[0034] After the circular plate lands on the two support blocks 38, the two sliders 17 are driven to descend simultaneously by the rotation of the threaded rod 16 driven by the motor 2 14. The support blocks 38 pass through the strip-shaped through hole on the limiting plate 19 from top to bottom. When the circular plate moves to the bottom of the mounting frame 13, the cylinder 2 18 drives the support blocks 38 to be pulled out from the enclosure, and the circular plate lands on the disc in the middle of the mounting frame 13.

[0035] Repeat the above operation. Each time a circular plate is cut, it is lowered by two support blocks 38 and placed on the circular plate below. This results in multiple circular plates being neatly stacked within the enclosure.

[0036] After the cutting work is completed and a sufficient number of circular plates are placed in the enclosure, the mounting frame 13 is rotated 180 degrees using motor 12. At this point, multiple circular plates are clamped by multiple limiting plates 19 and will not fall. Then, a container for collecting the circular plates is placed below the limiting plates 19. At this point, depending on the number of circular plates collected, the slider 17 is driven longitudinally again to align the end of the support block 38 with the corresponding circular plate, and then the two support blocks 38 are used to clamp it.

[0037] By subsequently enlarging the size of the enclosure, the multiple round plates located below the support block 38 will fall into the container as they lose the clamping grip of the limiting plate 19. The round plates clamped by the support block 38 and located above it will not fall. Repeating the above operation allows a specified number of round plates to be packaged into different containers, facilitating subsequent unified transfer and retrieval.

[0038] In this embodiment, as Figure 4 , Figure 5 , Figure 9 , Figure 10 As shown, it also includes an anti-crushing component; The anti-crushing component includes multiple blocks 25 that are longitudinally distributed and laterally slidably inserted on the front and rear limit plates 19. Each of the front and rear limit plates 19 is fixedly connected to a sliding groove plate 24. A pressing rod 22 for pressing the block 25 is slidably connected to the sliding groove of the sliding groove plate 24. Each of the front and rear limit plates 19 is rotatably connected to a winding roller 21. A baffle 26 is wound on the winding roller 21. The end of the baffle 26 is fixedly connected to one side of the pressing rod 22. A limit block 27 is fixedly connected to one side of the bottom of the sliding groove plate 24. The baffle 26 is slidably inserted on the limit block 27. A spring 33 is fixedly connected to one end of the block 25. The other end of the spring 33 is fixedly connected to the limit plate 19.

[0039] One end of the extrusion rod 22 is threadedly connected to a threaded rod 23. Both ends of the threaded rod 23 are rotatably connected to the slide plate 24. A motor 32 is fixedly connected to one side of the top of the slide plate 24. The output end of the motor 32 is fixedly connected to one end of the threaded rod 23. A motor 20 is fixedly connected to one side of the bottom of the slide plate 24. The output end of the motor 20 is fixedly connected to one end of the winding roller 21.

[0040] Specifically, in the above embodiments, although multiple circular plates can be stacked in the enclosure for subsequent packaging, as more circular plates are added to the enclosure, the pressure on the lower circular plates increases accordingly. This can easily lead to the circular plates breaking due to compression, thus affecting their quality.

[0041] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: In the initial state, the extrusion rod 22 is located at the bottom of the slide plate 24 and does not contact any of the stops 25. At this time, the ends of the stops 25 do not extend into the enclosure.

[0042] Each time a circular plate is placed within the enclosure, motor 32 drives threaded rod 23 to rotate, causing pressing rod 22 to rise a certain distance and contact one inclined surface of stop block 25, pressing stop block 25 into the enclosure. Spring 33 is compressed; for simplicity, only one spring 33 is shown in the diagram. The end of stop block 25, after being pressed by pressing rod 22, extends into the enclosure. Furthermore, as pressing rod 22 moves upward, motor 30 drives winding roller 21 to rotate, unwinding the baffle cloth 26 wound on winding roller 21. The baffle cloth 26 is used to prevent the compressed stop block 25 from returning to its original position.

[0043] By repeating the above operation, multiple blocks 25 can be used to support and separate the multiple circular plates, thereby preventing the lower circular plate from breaking due to pressure from the upper circular plate and ensuring the quality of the circular plates. Furthermore, when it is necessary to collect the circular plates, the pressing rod 22 resets, and the multiple blocks 25 will also reset accordingly, causing the circular plates to fall down in sequence.

[0044] In this embodiment, as Figure 7 As shown, the movable seat 4 is equipped with an auxiliary disengagement component; The auxiliary disengagement assembly includes a cylinder 36 fixedly connected to one side of the movable seat 4. A vacuum generator 34 is fixedly connected to the piston end of the cylinder 36, and a suction cup 35 is connected to the air inlet end of the vacuum generator 34.

[0045] Specifically, in the above embodiments, although the cut circular plate can be picked up by the support block 38, in some cases, the cut circular plate may get stuck due to friction and cannot fall normally, thus affecting the normal collection of the circular plate.

[0046] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When the cut circular plate gets stuck and cannot fall normally, cylinder 36 drives vacuum generator 34 and suction cup 35 to descend, causing suction cup 35 to adhere to the upper surface of the circular plate. Then, vacuum generator 34 is activated, using negative pressure to hold suction cup 35 in place. Suction cup 35 is then driven downwards, pushing the circular plate off the light guide plate and placing it stably on the two supports 38. Suction cup 35 then releases the circular plate. This avoids the cut circular plate getting stuck due to friction, preventing it from falling normally and thus affecting normal collection. Furthermore, compared to directly pushing the circular plate down, this method uses negative pressure to push it down and stably place it on the two supports 38, avoiding the bending or breakage that can occur when directly pushing the plate, as the plate is simultaneously subjected to the supporting and pushing forces of the supports 38.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
