[0002] In many fields such as liquid crystal displays and lighting, light guide plates, as a key optical component, play an important role in transforming line light sources or point light sources into uniform surface light sources. Their surface quality, such as flatness, roughness, and gloss, directly affects the light propagation efficiency and uniformity, and thus determines the display effect or lighting quality of the final product.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing light guide plate polishing devices with non-replaceable polishing heads are often designed and optimized for a certain type or class of light guide plates with specific specifications and requirements. This results in the device being unable to flexibly adjust the characteristics of the polishing head, such as the hardness, particle size, and shape of the polishing material, to adapt to diverse processing requirements when facing the polishing needs of different types of light guide plates. Utility Model Content
[0004] The technical problem to be solved by this utility model is that there are many types of light guide plates in the prior art. Depending on different application scenarios and design requirements, their materials, sizes and the polishing effects required on the surface vary significantly.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a light guide plate polishing device, including a polishing device body 1; a polishing mechanism 2 is installed on the top of the polishing device body 1, a rotating rod 3 is installed on the bottom of the polishing mechanism 2, an adjusting column 4 is provided at the bottom of the rotating rod 3, a rotating column 5 is rotatably connected inside the adjusting column 4, a polishing rod 6 is provided inside the rotating column 5, a polishing head 7 is fixedly connected to the bottom of the polishing rod 6, a limiting hole 8 is opened inside the polishing rod 6, arc blocks 9 are fixedly connected to both ends inside the adjusting column 4, and limiting grooves 10 are opened on both sides of the rotating column 5, the limiting grooves 10 are... A push block 11 is slidably connected, and an insertion rod 12 is fixedly connected to the side of the push block 11 near the limiting hole 8. The operator aligns the polishing rod 6 with the inside of the rotating column 5 and inserts it. At the same time, the operator rotates the rotating column 5. As the rotating column 5 rotates, it drives the push block 11 and the insertion rod 12 to move, and the push block 11 gradually contacts the arc block 9. When it moves to the thicker end of the arc block 9, the arc block 9 pushes the push block 11 to drive the insertion rod 12 to be inserted into the inside of the limiting hole 8, thus completing the limiting. Through the above settings, the operator can change polishing heads 7 of different specifications to polish the light guide plate.
[0017] Reference Figure 4As shown in this embodiment: a return spring 13 is fixedly connected to the side of the push block 11 near the limiting hole 8, and the side of the return spring 13 away from the push block 11 is fixedly connected to the inside of the limiting groove 10. When the worker moves the push block 11 into the limiting groove 10, the push block 11 compresses the return spring 13 to store force, and drives the insertion rod 12 to be inserted into the inside of the limiting hole 8. When the worker releases the insertion rod 12, the return spring 13 releases the stored force, pushing the push block 11 and the insertion rod 12 to move in opposite directions, so that the insertion rod 12 is disengaged from the inside of the limiting hole 8, so that the worker can separate the rotating column 5 and the polishing rod 6.
[0018] Reference Figure 4 As shown, in this embodiment: the size of the insertion rod 12 is adapted to the size of the limiting hole 8, and the surface of the insertion rod 12 is inserted into the interior of the limiting hole 8. When the insertion rod 12 is fully inserted into the interior of the limiting hole 8, a tight fit is formed between the two, which effectively prevents relative movement between the rotating column 5 and the polishing rod 6, thereby ensuring the stability and accuracy of the polishing process.
[0019] Reference Figure 4 As shown in this embodiment: both ends of the limiting groove 10 are provided with first sliding grooves 14, and both ends of the push block 11 are fixedly connected with first sliders 15. The surface of the first slider 15 is slidably connected to the inside of the first sliding groove 14. When the push block 11 moves inside the limiting groove 10, the first slider 15 slides inside the first sliding groove 14. This sliding connection design not only ensures the smoothness of the push block 11's movement, but also effectively prevents the push block 11 from deviating or shaking during the movement.
[0020] Reference Figure 4 As shown in this embodiment: limiting grooves 16 are provided on both sides of the adjusting column 4, and limiting holes 17 are provided on both sides of the rotating column 5. A return spring 18 is fixedly connected to the side of the limiting hole 17 near the limiting groove 16, and a limiting rod 19 is fixedly connected to the side of the return spring 18 near the limiting groove 16. When the operator rotates the rotating column 5 to push the push block 11 to drive the insertion rod 12 into the limiting hole 8, the limiting holes 17 at both ends of the rotating column 5 are parallel to the limiting groove 16, and the limiting rod 19 is quickly inserted into the limiting groove 16 under the action of the return spring 18, thus locking the rotating column 5 and preventing it from rotating during polishing.
[0021] Reference Figure 4As shown in this embodiment: both ends of the limiting hole 17 are provided with second sliding grooves 20, and both ends of the limiting rod 19 are fixedly connected with second sliders 21. The surface of the second sliders 21 is slidably connected to the interior of the second sliding grooves 20. This sliding connection design further enhances the connection stability and flexibility between components. When the limiting rod 19 slides inside the second sliding grooves 20 through the second sliders 21, it not only ensures that the limiting rod 19 can move smoothly as required, but also effectively limits its deviation in unexpected directions, thereby improving the reliability and durability of the overall structure.
[0022] Reference Figure 5 As shown in this embodiment: two guide blocks 23 are fixedly connected to the outer diameter surface of the rotating column 5, and two guide grooves 22 are opened inside the adjusting column 4. The surface of the guide groove 22 is slidably connected to the inside of the guide block 23. When the operator rotates the rotating column 5, the rotating column 5 drives the guide block 23 to rotate inside the guide groove 22. Through the above settings, the guide block 23 can slide stably in the guide groove 22. This sliding connection design not only enhances the connection strength between the rotating column 5 and the adjusting column 4, but also ensures the stability of the rotating column 5 during rotation.
[0023] Working principle: The operator aligns the polishing rod 6 with the interior of the rotating column 5 and inserts it. Simultaneously, the operator rotates the rotating column 5, which moves the push block 11 and the insertion rod 12, gradually bringing the push block 11 into contact with the arc block 9. When it reaches the thicker end of the arc block 9, the arc block 9 pushes the push block 11, causing the insertion rod 12 to insert into the limiting hole 8, thus completing the limiting. This setup allows the operator to change polishing heads 7 of different specifications to polish the light guide plate. When the operator moves the push block 11 into the limiting groove 10, the push block 11 compresses the return spring 13 to store force. The insertion rod 12 is inserted into the limiting hole 8. When the operator releases the insertion rod 12, the return spring 13 releases its stored force, pushing the push block 11 and the insertion rod 12 to move in opposite directions, causing the insertion rod 12 to disengage from the limiting hole 8. This allows the operator to separate the rotating column 5 and the polishing rod 6. When the insertion rod 12 is fully inserted into the limiting hole 8, a tight fit is formed between the two, effectively preventing relative movement between the rotating column 5 and the polishing rod 6, thus ensuring stability and accuracy during the polishing process. When the push block 11 moves inside the limiting groove 10, the first slider 15 moves accordingly. The sliding connection design of the first groove 14 ensures the smooth movement of the push block 11 and effectively prevents the push block 11 from shifting or shaking during movement. When the operator rotates the rotating column 5 to push the push block 11 with the arc block 9, causing the insertion rod 12 to be inserted into the limiting hole 8, the limiting holes 17 at both ends of the rotating column 5 are parallel to the limiting groove 16. Under the action of the return spring 18, the limiting rod 19 is quickly inserted into the limiting groove 16, completing the locking of the rotating column 5 and preventing self-rotation during polishing. This sliding connection design further enhances the connection stability and flexibility between components. When the limiting rod 19 slides inside the second slide groove 20 via the second slider 21, it not only ensures that the limiting rod 19 can move smoothly as required, but also effectively limits its deviation in unexpected directions, thereby improving the reliability and durability of the overall structure. When the operator rotates the rotating column 5, the rotating column 5 drives the guide block 23 to rotate inside the guide groove 22. Through the above settings, the guide block 23 can slide stably in the guide groove 22. This sliding connection design not only enhances the connection strength between the rotating column 5 and the adjusting column 4, but also ensures the stability of the rotating column 5 during rotation.
