Abstract
Description
Technical Field
[0001] This invention belongs to the field of light guide plate processing technology, and in particular relates to a light guide plate processing device. Background Technology
[0002] Current ultrafast rotary processing devices can only process arc-shaped micro-holes on light guide plates, and the micro-holes are also slightly arc-shaped. This leads to a reduction in the light-facing surface of the micro-holes and a decrease in the performance of the light guide plate. Therefore, in order to solve the above problems, this invention provides a high-speed rotary light guide plate processing device. Summary of the Invention
[0003] The purpose of this invention is to provide a light guide plate processing apparatus to solve the problems existing in the prior art.
[0004] To achieve the above objectives, the present invention provides a light guide plate processing apparatus, comprising:
[0005] A turntable is rotatably mounted on top of a base. A central reflector is provided at the center of the turntable. Multiple slide rails are evenly distributed around the turntable. A reflector is slidably mounted inside each slide rail. A rectangular through hole is provided below each reflector.
[0006] A truss, which is adjustablely mounted above the turntable, includes a top plate and support columns on both sides of the top plate, and the top plate is slidably mounted on the base via the support columns on both sides;
[0007] A light guide plate is disposed between the base and the turntable;
[0008] A laser is positioned above a central reflector. When the light guide plate is transmitted to a preset processing position and any one of the reflectors rotates into a preset area above the light guide plate, the laser is activated to process the light guide plate.
[0009] Optionally, each of the reflectors is mounted in a corresponding slide rail by means of a spring.
[0010] Optionally, mounting slots are symmetrically provided on both sides of the base, and the mounting slots are used to install the truss.
[0011] Optionally, one end of the mounting groove is provided with a threaded through hole, and a threaded rod is fitted inside the threaded through hole. A nut is engaged on the threaded rod, and the nut is fixedly connected to the support column. The support column is driven to slide by rotating the threaded rod.
[0012] Optionally, the central reflector is provided with multiple reflective surfaces, each of which corresponds to a reflector. The laser emitted by the laser is reflected by the central reflector to the reflector, and the laser reflected by the reflector is focused onto the light guide plate through the corresponding rectangular through-hole for processing.
[0013] Optionally, the bottom surface of the top plate and the top surface of each of the reflectors are located on the same horizontal plane.
[0014] The technical effects of this invention are as follows:
[0015] In this invention, the linear path movement of the reflector is restricted by a truss, changing the original curved path into a straight one. This results in the holes in the light guide plate being arranged in a straight line, with a more regular micro-hole morphology. Furthermore, this invention eliminates the need for dynamic adjustment of the turntable angular velocity, ensuring that the linear velocity of the reflector is the same at any position along the straight path of the truss, leading to more uniform dot patterns in the processed light guide plate.

[0028] like Figures 1-2 As shown, this embodiment provides a light guide plate processing apparatus, including:
[0029] Turntable 2 is rotatably mounted above base 1. A central reflector 6 is provided at the center of the turntable 2. Multiple slide rails 5 are evenly distributed around the turntable 2. A reflector 6 is slidably mounted inside each slide rail 5. A rectangular through hole 7 is provided below each reflector 6.
[0030] Truss 3, which is adjustablely installed above turntable 2, includes a top plate and support columns on both sides of the top plate. The top plate is slidably installed on base 1 through the support columns on both sides.
[0031] Light guide plate 9, which is disposed between base 1 and turntable 2;
[0032] A laser is positioned above the central reflector 6. When the light guide plate 9 is transmitted to the preset processing position and any one of the reflectors 6 rotates to the preset area above the light guide plate 9, the laser is activated to process the light guide plate 9.
[0033] Current ultrafast rotary processing equipment can only process arc-shaped micro-holes on the light guide plate 9, and the micro-hole morphology is also slightly arc-shaped. This will reduce the light-facing surface of the micro-holes and reduce the performance of the light guide plate 9. To solve the above problems, this embodiment sets up a truss 3 that contacts the reflector 6, changing the original arc path to a straight path. In this way, the holes punched in the light guide plate 9 are arranged in a straight line, and the micro-hole morphology is more regular.
[0034] The light guide plate processing device provided in this embodiment has the following specific structure:
[0035] A base 1 is provided, and a turntable 2 is provided on top of the base 1. A central reflector 6 is provided in the center of the turntable 2, and multiple slide rails 5 are evenly distributed around the turntable 2. The reflector 6 is slidably mounted on the turntable 2 via the slide rails 5. A rectangular through hole 7 is provided on the turntable 2 for the laser to pass through. The reflector 6 is connected to the end of the slide rail 5 by a spring. In the initial state of the spring, the reflector 6 is at the end of the slide rail 5.
[0036] The base 1 has symmetrical mounting slots 8 on both sides. The truss 3 is slidably mounted on the base 1 through the mounting slots 8. One end of the mounting slot 8 has a threaded through hole with a threaded rod inside. The threaded rod is fitted inside the threaded through hole and a nut is engaged on the threaded rod. The nut is fixed to the support column of the truss 3. The support column is driven to slide by rotating the threaded rod. The processing position can be controlled by controlling the position of the truss 3. The entire light guide plate 9 can be processed by controlling the truss 3 to move from left to right.
[0037] The truss 3, mounted on the base 1, contacts the reflector 6. The bottom surface of its top plate is on the same horizontal plane as the top surface of each reflector 6, thus restricting the movement of the reflector 6 along a straight path and changing the original curved path into a straight path. This results in the holes drilled in the light guide plate 9 being arranged in a straight line, with a more regular micro-hole morphology. Furthermore, this structure eliminates the need for dynamic adjustment of the angular velocity of the turntable 2, ensuring that the linear velocity of the reflector 6 is the same at any position along the straight path of the truss 3, resulting in more uniform dot patterns on the processed light guide plate 9. In operation, when the reflector 6 rotates to the underside of the truss 3, the spring is stretched, and the reflector 6 comes into contact with the truss 3. When the reflector 6 rotates away from the truss 3, the spring returns to its initial state, and the reflector 6 returns to its initial position.
[0038] Figure 2 This is a schematic diagram of the laser optical path in this embodiment. The central reflector 6 is provided with multiple reflective surfaces, and each reflective surface is provided in a one-to-one correspondence with each reflector 6. The laser located above the turntable 2 emits laser light, which passes through the central reflector 6, is reflected onto the reflector 6, and finally is focused onto the light guide plate 9 through the rectangular through hole 7 on the turntable 2.
[0039] In summary, this embodiment restricts the linear movement of the reflector 6 by using the truss 3, changing the original curved path into a straight path. This results in the holes in the light guide plate 9 being arranged in a straight line, with a more regular micro-hole morphology. Furthermore, this device eliminates the need for dynamic adjustment of the angular velocity of the turntable 2, ensuring that the linear velocity of the reflector 6 is the same at any position along the straight path of the truss 3, thus making the dot pattern of the processed light guide plate 9 more uniform.
[0040] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
