Description

Technical Field

[0001] The utility model relates to the technical field of diffusion plates, in particular to a fixing mechanism and a diffusion plate production and cutting device. Background Technique

[0002] Diffusion plates are made by chemical or physical means. When light travels through two media with different refractive indices, physical phenomena such as refraction, reflection, and scattering occur. By adding inorganic or organic light diffusing agents to substrates such as PMMA, PC, PS, PP, and HIPS, or by arranging an array of micro-feature structures on the substrate surface to artificially adjust the light, causing the light to refract, reflect, and scatter in different directions, thereby changing the light's traveling route and achieving sufficient dispersion of the incident light to produce an optical diffusion effect. There are three types of light diffusion plates. They are generally widely used in liquid crystal displays, LED lighting, and imaging display systems.

[0003] In the prior art, during the processing of diffusion plates, the processor needs to cut the diffusion plates according to the usage requirements of the diffusion plates. Professional diffusion plate cutting devices are generally used to cut diffusion plates. In traditional diffusion plate cutting devices, the structure for fixing the diffusion plates lacks flexibility and is not convenient for adjusting according to the size and thickness of the diffusion plates, which leads to the problem of poor practicability of the traditional fixing device for cutting diffusion plates.

When the output end of the cylinder 5 extends, the two moving plates 4 move away from each other, and when the output end of the cylinder 5 contracts, the two moving plates 4 move towards each other, so as to adjust the distance between the two U-shaped frames 6, and further effectively clamp and fix diffusion plates of different lengths. By rotating the threaded rod 9, the threaded sleeve 10 is driven to move, so that the threaded sleeve 10 drives the sliding frame 11 to slide up and down in the limiting sleeve 7, and further the soft pressing block 12 clamps and fixes the diffusion plate, realizing effective fixation of diffusion plates of different thicknesses.

[0025] Embodiment 2: On the basis of Embodiment 1, the rotating plate 2 is rotatably sleeved on the T-shaped shaft 13. The bottom of the T-shaped shaft 13 is fixedly connected to the bottom plate 1. One end of the connecting rod 3 is rotatably connected to the rotating plate 2 through a limit pin 14, and the other end of the connecting rod 3 is fixedly connected to the moving plate 4 through a limit pin 14. The T-shaped shaft 13 is fixedly installed on the bottom plate 1, so as to limit the rotating plate 2 through the T-shaped shaft 13. The connecting rod 3 drives the transmission between the rotating plate 2 and the moving plate 4 through the connection of the limit pin 14. The cylinder 5 is fixedly installed on the bottom plate 1 and the output end of the cylinder 5 is fixedly connected to one of the moving plates 4. The lower surface of the moving plate 4 is fixedly connected with a slider 15, and the slider 15 is slidably connected with the slide rail 16. The lower surface of the slide rail 16 is fixedly connected to the bottom plate 1. There are two moving plates 4 in a group and they are symmetrically arranged about the central plane of the bottom plate 1. The output end of the cylinder 5 is fixedly connected to one of the moving plates 4. The U-shaped frame 6 is fixedly installed on the upper surface of the moving plate 4, and the slider 15 is fixedly installed on the lower surface of the moving plate 4, so as to facilitate the movement of the moving plate 4 through the sliding connection between the slider 15 and the slide rail 16.

[0026] The diffusion plate production and cutting device is fixedly installed on the bottom plate 1, so as to facilitate subsequent cutting. The cylinder 5 is electrically connected to an external terminal control device. By controlling the expansion and contraction of the output end of the cylinder 5, the cylinder 5 drives the movement of one of the moving plates 4 fixedly connected to its output end. When this moving plate 4 moves, it will drive one end of the connecting rod 3 to move through the limit pin 14, so that the other end of the connecting rod 3 drives the rotating plate 2 to rotate on the T-shaped shaft 13, and then drives the movement of the other moving plate 4 through the transmission between the connecting rod 3 and the limit pin 14, thereby realizing the synchronous movement of the two moving plates 4. The moving plate 4 drives the U-shaped frame 6 to move under the sliding fit between the slider 15 and the slide rail 16. When the output end of the cylinder 5 extends, the two U-shaped frames 6 move away from each other. When the output end of the cylinder 5 contracts, the two U-shaped frames 6 move towards each other. In this way, the distance between the two U-shaped frames 6 can be adjusted in real time according to the length of the diffusion plate to be cut, and then the effective clamping and fixing of diffusion plates of different lengths can be realized, thus realizing the convenient adjustment function of this fixing mechanism.

[0027] Embodiment 3: On the basis of Embodiment 2, an upper gear 17 is provided on the upper side of the limit seat 8. A rotating shaft 18 is fixedly sleeved inside the upper gear 17. The rotating shaft 18 is rotatably sleeved inside the limit sleeve 7, and a handwheel 19 is fixedly sleeved at one end of the rotating shaft 18. The rotating shaft 18 is rotatably sleeved at the top of the limit sleeve 7. An upper gear 17 is fixedly sleeved on one side of the rotating shaft 18, and a handwheel 19 is fixedly sleeved on the outside of the other side of the rotating shaft 18. The rotation of the rotating shaft 18 is facilitated by the handwheel 19. A lower gear 20 is meshed with the lower side of the upper gear 17. The lower gear 20 is sleeved on the top of the threaded rod 9 and is fixedly connected to the threaded rod 9. The upper gear 17 and the lower gear 20 are in meshing transmission. A bearing is fixedly installed on one side of the limit seat 8 fixedly installed inside the limit sleeve 7, thus facilitating the rotation of the threaded rod 9. The lower gear 20 is fixedly sleeved on the top end of the threaded rod 9. The sliding frame 11 is slidably sleeved inside the limit sleeve 7. The soft pressing block 12 is fixedly connected to the sliding frame 11. An anti-slip plate 21 is provided on the lower side of the soft pressing block 12. The anti-slip plate 21 is fixedly connected to the U-shaped frame 6. The sliding frame 11 is slidably connected to the limit sleeve 7. The limit sleeve 7 performs sliding limit on the sliding frame 11. The soft pressing block 12 presses and fixes the diffusion plate, thus preventing the diffusion plate from being damaged. The anti-slip plate 21 is fixedly installed on the U-shaped frame 6, so that through the anti-slip function of the anti-slip plate 21, the diffusion plate is more stable during the cutting process.

[0028] When the two U-shaped frames 6 are adjusted to fit the size of the diffusion plate, the diffusion plate is placed between the U-shaped frames 6. At this time, by rotating the handwheel 19, the handwheel 19 drives the rotating shaft 18 fixedly sleeved inside it to rotate inside the limit sleeve 7. The rotating shaft 18 drives the upper gear 17 to rotate. The upper gear 17 is immediately meshed with the lower gear 20 for transmission. The lower gear 20 drives the threaded rod 9 to rotate under the limiting action of the limit seat 8. The threaded rod 9 drives the threaded sleeve 10 sleeved thereon. The threaded sleeve 10 is fixedly installed inside the sliding frame 11. Thus, the threaded sleeve 10 drives the sliding frame 11 to move synchronously, and further enables the sliding frame 11 to move inside the limit sleeve 7. By adjusting the rotation direction of the handwheel 19, the sliding frame 11 can be lifted and lowered inside the limit sleeve 7. In this way, the distance between the bottom of the sliding frame 11 and the U-shaped frame 6 can be adjusted in real time according to the thickness of the diffusion plate to be cut, achieving the effect of clamping and fixing diffusion plates with different thicknesses, and thus realizing the function that the fixing mechanism can be adjusted according to the thickness of the diffusion plate. The soft pressing block 12 is driven by the sliding frame 11 to press and fix the diffusion plate. At the same time, both sides of the lower surface of the diffusion plate are in contact with the anti-slip plate 21, further increasing the stability of the clamping and fixing of the diffusion plate.
