Description

Technical Field

[0001] This utility model relates to the field of diffusion plate edge trimming, and in particular to an edge trimming device for diffusion plate processing. Background Art

[0002] A diffuser plate is a material used in optics, electronics, and other fields, possessing specific optical and high-temperature resistance properties. It is commonly used in optical devices, display devices, LED lighting, and other products. The main function of a diffuser plate is to uniformly scatter or transmit light, allowing the light to be distributed or diffused more evenly, thereby achieving the purpose of softening the light and improving light utilization.

[0003] A search revealed a cutting device for processing diffuser plates, with publication number CN220030385U. The device includes a base and a support. A housing is fixedly mounted in the center of the base's bottom end. A lead screw is rotatably connected inside the housing. The lead screw is threadedly connected to a slide table via a threaded sleeve. A slider is fixedly mounted in the center of the slide table's top end. A limiting plate is fixedly connected to the top of the slider. A support is fixedly mounted on one side of the base's top end. This invention places one side of the diffuser plate against one side of the limiting plate. The limiting plate can limit the diffuser plate and prevent it from tilting. By controlling the extension of the hydraulic rod of the hydraulic cylinder, a spring can be compressed. The spring can then exert pressure on a pressure plate, which, through a rubber pad, can press the diffuser plate firmly.

[0004] Based on the aforementioned patent, by attaching one side of the diffuser plate to one side of the limiting plate, the limiting plate can limit the diffuser plate and prevent it from tilting. By controlling the extension of the hydraulic rod of the hydraulic cylinder, the hydraulic rod can push the horizontal plate down. When the horizontal plate drives the pressure plate down to apply pressure to the diffuser plate, it can compress the spring. The spring can then react the pressure to the pressure plate. The pressure plate can press the diffuser plate tightly through the rubber pad. Since the height of the pressure plate is lower than the height of the bottom of the blade, the diffuser plate can be quickly fixed before the blade reaches it. When the blade at the bottom of the horizontal plate reaches the diffuser plate, it can prevent the diffuser plate from shifting. The blade can then cut the edge of the diffuser plate without manual cutting, saving manpower and ensuring the quality of the cut edge of the diffuser plate. However, when the device cuts the diffuser plate, it can only perform single-sided cutting, and the efficiency of cutting multiple edges of the plate is relatively low. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4This utility model provides an embodiment of a cutting device for processing diffuser plates, comprising a support platform 1, a fixed mounting bracket 2 fixedly connected to the top of the support platform 1, a cylinder 6 fixedly connected to the middle of the top of the fixed mounting bracket 2, first limiting rods 5 slidably connected to both sides of the fixed mounting bracket 2, a pressing plate 3 fixedly connected to the bottom of the first limiting rods 5, a push rod 7 fixedly connected to the middle of the top of the pressing plate 3, pressing fixing components installed on both sides of the pressing plate 3, and cutting blades 9 fixedly connected to both sides of the bottom of the pressing plate 3. Positioning plates 11 slidably connected to both sides of the support platform 1, and a mounting frame 13 fixedly connected to the middle of the bottom of the support platform 1. A bidirectional threaded rod 21 is rotatably connected inside the mounting frame 13, and a drive is fixedly connected to the left side of the mounting frame 13. The drive motor 12 and the support platform 1 are equipped with waste collection components on both sides of the bottom end. The support platform 1 has cutting slots 10 on both sides. The pressing and fixing component includes multiple second limiting rods 8 located on both sides of the pressing plate 3. The bottom end of the second limiting rod 8 is fixedly connected to a positioning pressing block 4. The bottom end of the positioning pressing block 4 is fixedly connected to a friction increasing rubber pad 20. The top two sides of the friction increasing rubber pad 20 are connected to the bottom two sides of the pressing plate 3 through compression springs 19. The outer sides of the second limiting rod 8 are respectively slidably connected to the inside of the pressing plate 3. The drive end of the drive motor 12 is fixedly connected to the left side of the bidirectional threaded rod 21. The output end of the cylinder 6 is fixedly connected to the top of the push rod 7. The outer two sides of the drive motor 12 are respectively threadedly connected to the inside of the positioning plate 11.

[0026] The diffuser plate to be trimmed is placed on the top of the support platform 1. At this time, the drive motor 12 is started to drive the bidirectional threaded rod 21 to rotate. As the external thread of the bidirectional threaded rod 21 contacts the internal thread of the positioning plate 11, and the directions of the threads on both sides of the external threaded rod 21 are opposite, the positioning plate 11 is moved inward at the same time to fix the diffuser plate. At this time, the cylinder 6 is started to drive the push rod 7 to push downward, pressing the pressing plate 3 downward. The first limiting rod 5 at the bottom of the positioning pressing block 4 contacts the surface of the plate. As the pressing plate 3 continues to press, the compression spring 19 is compressed and deformed. The compression spring 19 generates a downward compressive force on the positioning pressing block 4, further fixing the plate. When the cutting blade 9 contacts the edge of the plate and cuts, the cutting blade 9 enters the interior of the cutting groove 10, thereby completely cutting the edge of the diffuser plate. The device can cut both sides of the plate at the same time. When both sides of the plate are uneven, the efficiency of the cutting work can be improved.

[0027] Reference Figure 1 , Figure 2 and Figure 5The waste collection assembly includes collection frames 16 located on both sides of the bottom end of the support platform 1. Support grooves 18 are provided on both sides of the inside of the collection frame 16. Support sliders 14 are slidably connected inside the support grooves 18. Collection boxes 15 are fixedly connected to the inside of the support sliders 14. Traction handle grooves 17 are provided at the bottom end of the collection boxes 15.

[0028] The cut diffuser plate scrap will fall downwards through the groove 10. The scrap will fall into the collection box 15 under the constraint of the collection frame 16. The collection box 15 is supported by the sliding between the support slider 14 and the support groove 18. When there is too much scrap inside, the collection box 15 is pulled outwards by the traction handle groove 17, thereby cleaning up the scrap inside. This prevents the scrap after cutting from accumulating on the table surface and affecting the subsequent cutting accuracy of the diffuser plate, and facilitates the handling of scrap.

[0029] Working principle: The diffuser plate to be trimmed is placed on the top of the support platform 1. The drive motor 12 is then activated, rotating the bidirectional threaded rod 21, which simultaneously moves the positioning plate 11 inwards to fix the diffuser plate. Simultaneously, the cylinder 6 is activated, pushing the push rod 7 downwards, pressing the pressing plate 3 down. The first limiting rod 5 at the bottom of the positioning pressing block 4 contacts the surface of the plate. As the pressing plate 3 continues to press, the compression spring 19 deforms, generating a downward compressive force on the positioning pressing block 4, further compressing the plate. When the cutting blade 9 contacts the edge of the plate and cuts, the cutting blade 9 enters the inside of the cutting groove 10, thereby completely cutting the edge of the diffuser plate. The cut diffuser plate waste will fall downwards along the groove of the cutting groove 10. The waste will fall into the inside of the collection box 15 under the restriction of the collection frame 16. The entire collection box 15 is supported by the sliding between the support slider 14 and the support groove 18. When there is too much waste inside, the collection box 15 is pulled outwards by the traction handle groove 17, thereby completing the cleaning of the waste inside.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
