[0003] For example, an automatic LED bead cutting device, as disclosed in announcement number CN218428569U, includes a collection box with multiple support feet at its bottom and a processing table at its top. Support rods are mounted on both sides of the processing table at the top of the collection box, and a support frame is mounted on the top of each support rod. A cutting mechanism is mounted on the support frame above the processing table. A length measuring mechanism is provided at the top of the collection box. The above-mentioned prior art has the following technical problems:

[0004] Existing cutting devices are not suitable for continuous cutting of LED chips. They can only cut one set of LED chips at a time. After the LED chips are cut, they need to be removed and another set of LED chips needs to be clamped, resulting in low overall work efficiency.

[0005] Therefore, we propose an LED chip cutting device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an LED chip cutting device to solve the problem mentioned in the background art that the existing cutting devices on the market are not convenient for continuous cutting of LED chips, and can only cut one set of LED chips at a time. After the LED chips are cut, they need to be removed and another set of LED chips needs to be clamped, which leads to low overall work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED bead cutting device, comprising a support platform and a connecting frame fixed to the upper end of the support platform. A power cylinder is installed in the middle of the upper end of the connecting frame, and a limit cover is fixed to the telescopic end of the power cylinder. A drive motor is connected to the side of the limit cover, and a cutting disc is fixed to the output end of the drive motor. A movable guide plate is installed in the middle of the support platform, and the lower middle of the movable guide plate is installed on the output end of a servo motor. The movable guide plate has a guide groove, and a limiting component for cutting LED bead sheets is installed inside the guide groove. The bottom of the limiting component is connected to the movable guide plate through an auxiliary spring, and a magnetic block is installed at the end of the rod on the limiting component. An electromagnet is installed on the transverse central axis of the support platform.

[0008] Preferably, the movable guide plate has multiple guide grooves evenly distributed on it, and each guide groove is equipped with a limiting component inside.

[0009] By adopting the above technical solution and setting multiple guide slots, multiple processing stations can be formed on the movable guide plate.

[0010] Preferably, the limiting component includes a movable block, and a clamping screw is installed on the side of the movable block, and a fixed block is connected to the lower end of the clamping screw.

[0011] By adopting the above technical solution, the fixed block at the lower end of the clamping screw can be moved by rotating the clamping screw on the moving block.

[0012] Preferably, the clamping screw and the fixing block are symmetrically arranged about the transverse central axis of the moving block, and the sides of the clamping screw and the moving block are threaded together.

[0013] By adopting the above technical solution, the symmetrically arranged clamping screws and fixing blocks facilitate the positioning of the LED light bead sheets to be cut.

[0014] Preferably, the lower outer wall of the movable block and the inner wall of the guide groove are in contact with each other, and the movable block can slide inside the guide groove.

[0015] By adopting the above technical solution, the outer wall of the moving block and the inner wall of the guide groove fit together, thereby ensuring the stability of the moving block when it moves in the guide groove.

[0016] Preferably, the magnetic properties of the magnetic block on the movable block rod are the same as those of the electromagnet after it is energized.

[0017] By adopting the above technical solution, when the electromagnet is energized, it can generate a repulsive magnetic force on the magnetic block on the moving block rod.

[0018] Preferably, a protective upright plate is provided above the movable guide plate, and the protective upright plate is eccentrically positioned above the movable guide plate, and the protective upright plate is made of transparent material.

[0019] By adopting the above technical solution, the setting of the protective plate not only allows for the replacement of LED chips on the blocked limiting components during processing, but also facilitates the observation of the processing status of the remaining LED chips.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the LED lamp bead cutting device can improve the cutting efficiency of LED lamp beads by setting multiple switchable processing stations on the worktable and rotating and adjusting to the next station after processing at one station is completed.

[0021] 1. It is equipped with a movable guide plate. By rotating the movable guide plate, the guide groove and the limiting component on it can switch positions. The repulsive magnetic force generated by the electromagnet on the magnetic block after being energized can make the limiting component move towards the center of the movable guide plate, which facilitates the subsequent cutting of LED lamp beads.

[0022] 2. A clamping screw is provided. The rotation of the clamping screw can move the fixing block at the lower end, thereby clamping and limiting the LED lamp bead sheet, thus ensuring the stability of the LED lamp bead sheet during cutting.

[0023] 3. Equipped with a protective stand, the LED beads on the limiting component away from the cutting disc can be replaced during the cutting process. The protective stand also blocks flying debris during the cutting process. Furthermore, the protective stand is made of transparent material, allowing real-time observation of the cutting status of the remaining LED beads. Attached Figure Description

[0030] 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.

[0031] Example 1: Please refer to Figures 1-5 Existing cutting devices are not suitable for continuous, uninterrupted cutting of LED chips. They can only cut one set of LED chips at a time. After cutting, the LED chips need to be removed and re-clamped to form another set, resulting in low overall work efficiency. To solve this technical problem, this embodiment discloses the following technical content: an LED chip cutting device, including a support platform 1 and a connecting frame 2 fixed to the upper end of the support platform 1. A power cylinder 3 is installed in the middle of the upper end of the connecting frame 2, and a limit cover 4 is fixed to the telescopic end of the power cylinder 3. A drive motor 5 is connected to the side of the limit cover 4, and a cutting disc 6 is fixed to the output end of the drive motor 5. A movable guide plate 7 is installed in the middle of the support platform 1, and the lower middle of the movable guide plate 7 is installed on the output end of a servo motor. The movable guide plate 7 has a guide groove 8, and a guide groove 8 is installed inside the guide groove 8. The limiting component 9 for cutting LED beads has its bottom connected to the movable guide plate 7 via an auxiliary spring 10. A magnetic block 11 is installed at the end of the rod on the limiting component 9. An electromagnet 12 is installed on the transverse central axis of the support platform 1. Multiple guide grooves 8 are evenly distributed on the movable guide plate 7, and a limiting component 9 is installed inside each guide groove 8. The limiting component 9 includes a moving block 901, and a clamping screw 902 is installed on the side of the moving block 901. A fixing block 903 is connected to the lower end of the clamping screw 902. The clamping screw 902 and the fixing block 903 are symmetrically arranged about the transverse central axis of the moving block 901, and the clamping screw 902 and the side of the moving block 901 are threaded together. The lower outer wall of the moving block 901 and the inner wall of the guide groove 8 are in contact with each other, and the moving block 901 can slide inside the guide groove 8. The magnetic block 11 on the rod of the moving block 901 has the same magnetism as the electromagnet 12 after it is energized.

[0032] When cutting LED chips, the LED chips are sequentially placed onto the limiting component 9 in the movable guide plate 7. Then, the clamping screw 902 is rotated, which causes the lower fixing block 903 to clamp the LED chips. Next, the electromagnet 12 is energized, which generates a repulsive magnetic force on the magnetic blocks 11 located on the same straight line and close to each other. This causes the moving block 901 to move towards the center of the movable guide plate 7. After the moving block 901 is in place, the limiting cover 4 is moved downward by the power cylinder 3. After the limiting cover 4 moves downward, the rotating cutting disc 6 controlled by the drive motor 5 cuts the LED chips on the moving block 901. After one moving block 901 is cut, the movable guide plate 7 is rotated by the servo motor, so that the LED chips on the next moving block 901 are cut in the same way. This process is repeated to improve the cutting efficiency of the LED chips.

[0033] Example 2: The technical content disclosed in this example is a further improvement on the basis of Example 1 above. The following technical content is disclosed in this example: a protective plate 13 is provided above the movable guide plate 7, and the protective plate 13 is eccentrically positioned above the movable guide plate 7, and the protective plate 13 is made of transparent material.

[0034] By setting the protective plate 13, the movable guide plate 7 can be separated, so that the LED lamp beads on the limiting component 9 on the side away from the cutting plate 6 can be replaced during the cutting process without stopping the machine. At the same time, the protective plate 13 can block the debris generated during the cutting of other LED lamp beads. Moreover, the protective plate 13 is made of transparent material, so the cutting status on the other limiting components 9 can be observed through the protective plate 13.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
