Description

Technical Field

[0001] This application relates to the field of light guide plate processing technology, and in particular to a light guide plate cutting mechanism. Background Technology

[0002] A rapid cutting mechanism for light guide plates disclosed on the Chinese patent website (authorization announcement number: CN221717034U) solves the problem that in the production of light guide plates, large pieces of raw material need to be cut into small pieces. However, existing cutting devices require workers to manually remove and stack the cut pieces after each piece is cut, which is labor-intensive and inefficient. Nevertheless, the following problems still exist:

[0003] In practical use, existing light guide plate cutting mechanisms rely solely on a single laser blade to cut light guide plates, limiting the overall cutting speed and resulting in low work efficiency. Furthermore, the current cutting method has significant limitations in terms of cutting length and width, as the cutting length and width are often fixed. This means that when it is necessary to cut light guide plates of different widths to different lengths, this cutting method is difficult to meet the requirements. Utility Model Content

[0004] In order to solve the technical problems of low cutting efficiency and difficulty in adjusting the cutting length and width of existing light guide plate cutting mechanisms, this application provides a light guide plate cutting mechanism.

[0005] This application provides a light guide plate cutting mechanism, which adopts the following technical solution:

[0006] A light guide plate cutting mechanism includes a base, a conveyor belt on the top of the base, a support frame fixedly connected to one side of the base, and a collection box on the side of the support frame away from the base. A height adjustment component for adjusting the height of the laser cutter is vertically arranged on the top of the support frame. A length adjustment component, including a threaded rod, is arranged along the conveyor belt's conveying direction on the side of the height adjustment component closest to the conveyor belt. A cutting component, including a bidirectional threaded rod, is sleeved on the threaded rod, and two laser cutters reciprocate synchronously along the axial direction of the bidirectional threaded rod.

[0007] Optionally, the height adjustment assembly includes a hydraulic cylinder, which is fixedly connected to the top of the support frame. A sliding plate is fixedly connected to the output end of the hydraulic cylinder. Two sliding groove plates are fixedly connected to the side of the support frame near the base, and the sliding plate is slidably connected between the two sliding groove plates.

[0008] Optionally, the length adjustment assembly further includes an adjustment frame, which is threadedly connected to the threaded rod. The threaded rod is rotatably connected to one side of the sliding plate, and two guide rods are symmetrically fixedly connected to the sliding plate.

[0009] Optionally, both guide rods extend through the side of the adjusting frame, and a handle is fixedly connected to one end of the threaded rod.

[0010] Optionally, the cutting assembly further includes a servo motor, which is fixedly connected to the upper surface of the adjustment frame. The output end of the servo motor is coaxially fixedly connected to a pulley, which is rotatably connected to a bracket on one side of the adjustment frame.

[0011] Optionally, the bidirectional threaded rod is rotatably connected between the two side walls at the bottom of the adjusting frame, and a mating pulley is fixedly connected to one end of the bidirectional threaded rod near the pulley. The pulley and the mating pulley are connected by belt drive.

[0012] Optionally, both sides of the bidirectional threaded rod are threadedly connected to a fixing plate, a limiting rod is fixedly connected between the two side walls of the adjusting frame, the limiting rod passes through the two fixing plates, and the laser knife is fixedly connected to the bottom of the fixing plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. By setting up height adjustment components and length adjustment components, and controlling the extension and retraction of hydraulic cylinders, the sliding plate is driven to slide between two sliding groove plates, thereby changing the overall up-and-down action of the cutting components to achieve cutting and separation.

[0015] 2. By rotating the handle, the threaded rod can be rotated. With the support and limit of the guide rod, the distance between the adjusting frame and the support frame can be changed, making it easy to adjust the adjusting frame to the required cutting length.

[0016] 3. By setting up a cutting component, a servo motor drives a pulley to rotate, which in turn drives a mating pulley to rotate, thereby driving a bidirectional threaded rod to rotate. Under the action of a limit rod, two fixed plates can move relative to each other on the bidirectional threaded rod. Two laser cutters can cut the light guide plate simultaneously, greatly improving cutting efficiency and enabling the cutting of light guide plates of different widths. Attached Figure Description

[0020] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0021] Reference Figures 1-3 A light guide plate cutting mechanism includes a base 1, a conveyor belt 2 on the top of the base 1, a support frame 3 fixedly connected to one side of the base 1, and a collection box 4 on the side of the support frame 3 away from the base 1; a height adjustment component for adjusting the height of the laser blade is vertically arranged on the top of the support frame 3; a length adjustment component is arranged along the conveying direction of the conveyor belt 2 on the side of the height adjustment component near the conveyor belt 2, and the length adjustment component includes a threaded rod 9; a cutting component is sleeved on the threaded rod 9, and the cutting component includes a bidirectional threaded rod 14, and two laser blades reciprocate synchronously along the axial direction of the bidirectional threaded rod.

[0022] To enable the height and length adjustment components to operate, the height adjustment component includes a hydraulic cylinder 5, which is fixedly connected to the top of the support frame 3. A sliding plate 7 is fixedly connected to the output end of the hydraulic cylinder 5. Two sliding groove plates 8 are fixedly connected to the side of the support frame 3 near the base 1. The sliding plate 7 is slidably connected between the two sliding groove plates 8. The hydraulic cylinder 5 drives the sliding plate 7 to slide between the two sliding groove plates 8, adjusting the distance between the overall cutting component and the conveyor belt 2 to facilitate cutting the light guide plate. The length adjustment component also includes an adjustment frame 10, which is connected to a threaded rod 9. The threaded connection is such that the threaded rod 9 is rotatably connected to one side of the sliding plate 7. Two guide rods 11 are symmetrically fixedly connected to the sliding plate 7. The two symmetrically arranged guide rods 11 provide auxiliary support for the adjusting frame 10 to improve the stability of the device. Both guide rods 11 pass through the side of the adjusting frame 10. One end of the threaded rod 9 is fixedly connected to the handle 6. The rotation of the handle 6 drives the threaded rod 9. The guide rods 11 limit the adjusting frame 10 to ensure that the adjusting frame 10 acts parallel to the threaded rod 9, so as to change the distance between the adjusting frame 10 and the support frame 3.

[0023] By setting up height adjustment components and length adjustment components, and by controlling the extension and retraction of hydraulic cylinder 5, the sliding plate 7 is driven to slide between two sliding groove plates 8, thereby changing the overall up-and-down action of the cutting component to achieve cutting and separation. By turning handle 6, the threaded rod 9 is driven to rotate, and under the support and limit of guide rod 11, the distance between adjustment frame 10 and support frame 3 can be changed, making it easy to adjust adjustment frame 10 to the required cutting length.

[0024] To enable the cutting assembly to operate, the cutting assembly also includes a servo motor 12, which is fixedly connected to the upper surface of the adjusting frame 10. A pulley 13 is coaxially fixedly connected to the output end of the servo motor 12. The pulley 13 is rotatably connected to a bracket on one side of the adjusting frame 10. The servo motor 12 drives the pulley 13, and the bracket on one side of the adjusting frame 10 supports the pulley 13, thus achieving transmission. A bidirectional threaded rod 14 is rotatably connected between the two side walls of the bottom of the adjusting frame 10. A mating pulley 15 is fixedly connected to the end of the bidirectional threaded rod 14 near the pulley 13. The pulley 13 and the mating pulley 15... The pulley 15 is connected via belt drive, and the belt drive drives the pulley 15 to rotate, thereby driving the bidirectional threaded rod 14 to rotate. Both sides of the bidirectional threaded rod 14 are threadedly connected to the fixing plates 16. The two side walls of the adjusting frame 10 are fixedly connected to the limiting rod 17, which passes through the two fixing plates 16. The laser cutter is fixedly connected to the bottom of the fixing plates 16. The limiting rod 17 limits the two fixing plates 16 to ensure that when the bidirectional threaded rod 14 rotates, the two fixing plates 16 move relative to each other on the bidirectional threaded rod 14, so as to improve the cutting efficiency of the laser cutter at the bottom of the fixing plate 16 on the light guide plate.

[0025] By setting up a cutting component, the servo motor 12 drives the pulley 13 to rotate, and the belt drives the mating pulley 15 to rotate, thereby driving the bidirectional threaded rod 14 to rotate. Under the action of the limit rod 17, the two fixed plates 16 can move relative to each other on the bidirectional threaded rod 14. The two laser cutters can cut the light guide plate at the same time, which greatly improves the cutting efficiency and can cut light guide plates of different widths.

[0026] Working principle: The light guide plate is conveyed to the appropriate position by the conveyor belt 2. The adjustment frame 10 is adjusted to the required cutting length by rotating the handle 6. The hydraulic cylinder 5 is controlled to extend and retract so that the laser knife is in contact with the surface of the light guide plate, which can cut light guide plates of different widths. Then, the servo motor 12 is driven to drive the bidirectional threaded rod 14 to rotate under the transmission of the pulley 13, the cooperating pulley 15 and the belt. Under the limit of the limit rod 17, the two fixed plates 16 move relative to each other, which improves the cutting efficiency of the laser knife on the light guide plate. After the cutting is completed, the cut light guide plate part is conveyed to the collection box 4 by the conveyor belt 2.

[0027] 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.
