Technical Field
[0001] This utility model relates to the field of LED testing technology, and in particular to an LED light strip testing fixture. Background Technology
[0002] In the manufacturing process of LED light strips, the testing stage is a crucial step in ensuring product quality. Precise testing of indicators such as brightness, color temperature, and electrical performance is required using specialized testing fixtures. One of the core functions of these fixtures is to stably clamp and fix the light strip and the supporting plate, ensuring accurate and displacement-free positioning of the strip during testing and providing a reliable testing benchmark for the equipment. With the diversification of LED light strip applications, their specifications (such as length, width, and thickness) are showing a trend towards diversification, placing higher demands on the adaptability and flexibility of the testing fixtures.
[0003] Existing LED strip testing fixtures mostly employ a fixed clamping structure. Their core mechanical structure typically includes a base, a fixed bracket, and a manual clamping device. The fixed bracket is rigidly connected to the base and its position is not adjustable. The manual clamping device is usually a bolt-tightening or snap-fit structure. Technically, the clamping plate is pushed or the snap-fit is engaged by manually rotating the bolts, using mechanical force to press and fix the LED strip and strip plate in a preset position. During testing, the bolt tightening depth must be adjusted according to the LED strip's fixing dimensions, or a corresponding snap-fit specification must be selected. Manual experience is crucial to ensure appropriate clamping force, preventing displacement due to excessive looseness or damage due to excessive tightness. However, in the existing technology, the dimensions of the fixed bracket and the manual clamping device are fixed. When inspecting light strips and light strip plates of different lengths and widths, it is difficult to adapt to the new specifications of the products by adjusting the clamping structure. The entire set of inspection fixtures adapted to the corresponding size must be replaced to complete the inspection operation, resulting in a narrow range of fixture compatibility. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an LED light strip testing fixture, which aims to improve the problems of traditional fixtures having fixed clamping dimensions, being unable to accommodate light strips and light strip plates of different lengths and widths, requiring frequent fixture changes and having a narrow range of compatibility.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED light strip testing fixture, including a support, a bracket fixedly connected to the upper surface of the support, a hydraulic rod fixedly connected to the outer wall of the bracket, a pressure plate fixedly connected to the output end of the hydraulic rod, a left-right symmetrical clamping assembly provided above the support, and a quick-release assembly provided on the outer wall of the support; The clamping assembly includes a threaded post disposed above the support. A first fixing post is threadedly connected to the outer wall of the threaded post. A spring is fixedly connected to the outer wall of the first fixing post. A telescopic strip is fixedly connected to the outer wall of the first fixing post. A telescopic frame is slidably connected to the outer wall of the telescopic strip. A second fixing post is fixedly connected to the outer wall of the telescopic strip. A limit plate is fixedly connected to the inner wall of the second fixing post. A second rotating shaft is fixedly connected to the outer wall of the telescopic strip. The outer wall of the limit plate is attached to the inner wall of the connecting frame. A connecting frame is rotatably connected to the outer wall of the second rotating shaft. A first rotating shaft is fixedly connected to the inner wall of the connecting frame. A frame is fixedly connected to the outer wall of the telescopic frame. The inner wall of the frame is fixedly connected to the outer wall of the support plate. A guide plate is fixedly connected to the lower surface of the support plate. A rack is fixedly connected to the outer wall of the guide plate. A motor is fixedly connected to the inner wall of the support. A gear is fixedly connected to the output end of the motor. The gear meshes with the rack. A second fixing plate is fixedly connected to one end of the threaded post.
[0006] Furthermore, the quick-release assembly includes a connecting rod, which is disposed on the outer wall of the support. A fixing plate one and a fixing plate three are rotatably connected to the outer wall of the connecting rod. The inner walls of the fixing plate one and the fixing plate three are fixedly connected to the outer wall of the support. A clamping plate is fixedly connected to the lower surface of the fixing plate three, and the inner wall of the clamping plate is attached to the outer wall of the connecting rod.
[0007] Furthermore, two left-right symmetrical sliders are fixedly connected to the outer wall of the fixed column, and the inner wall of the frame is provided with left-right symmetrical sliding grooves, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove.
[0008] Furthermore, one end of the spring is fixedly connected to the inner wall of the frame, and the spring is disposed on the inner wall of the frame.
[0009] Furthermore, the outer wall of the rotating shaft is slidably connected to the inner wall of the telescopic frame, and the connecting frame is disposed on the inner wall of the telescopic frame.
[0010] Furthermore, the lower surface of the support plate is attached to the upper surface of the support, and the upper surface of the support is provided with symmetrical guide grooves. The outer wall of the guide plate is slidably connected to the inner wall of the guide groove.
[0011] Furthermore, the outer wall of the guide plate is attached to the inner wall of the support, and the outer wall of the rack is attached to the inner wall of the support.
[0012] Furthermore, the gear meshes with two symmetrical racks.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the gear to mesh with the upper and lower symmetrical racks, so that the two support plates can adjust and clamp the light strip plate in the guide groove driven by the rack. Then, the fixed plate position is adjusted up and down by the threaded column itself, and the spring connected to the threaded column slides in the slide groove through the telescopic bar to limit the sliding of the fixed plate, thereby better adjusting and clamping the light strip. This solves the problems of traditional tooling clamping size being fixed, difficult to be compatible with light strips and light strip plates of different lengths and widths, requiring frequent tooling changes and having a narrow range of applicability. It reduces light strip displacement, improves the reliability of test results, reduces the frequency of tooling changes, reduces equipment investment costs, and reduces the light strip damage rate caused by improper clamping.
[0014] 2. In this utility model, the connecting rod is placed inside the first fixing plate and the second fixing plate, so that the groove at the end of the connecting rod is limited in the clamping plate on the lower surface of the second fixing plate, and the clamping part of the clamping plate is just in the groove at the end of the connecting rod. When disassembling, the connecting rod is rotated so that the groove at the end of the connecting rod rotates away from the clamping side, thereby enabling quick disassembly, improving the efficiency of detection and switching, enhancing the flexibility of equipment adaptation, reducing equipment downtime for maintenance, and reducing maintenance labor costs.

[0017] 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.
[0018] Reference Figure 1 - Figure 5 An embodiment of this utility model is provided: an LED light strip testing fixture, including a support 1, a bracket 2 fixedly connected to the upper surface of the support 1, a hydraulic rod 4 fixedly connected to the outer wall of the bracket 2, a pressure plate 5 fixedly connected to the output end of the hydraulic rod 4, a left-right symmetrical clamping assembly provided above the support 1, and a quick-release assembly provided on the outer wall of the support 1. The clamping assembly includes a threaded post 11, which is positioned above the support 1. A fixed post 13 is threadedly connected to the outer wall of the threaded post 11. A spring 10 is fixedly connected to the outer wall of the fixed post 13. A telescopic strip 18 is fixedly connected to the outer wall of the fixed post 13, with one end of the telescopic strip 18 fixedly connected to the outer wall of the fixed post 13, allowing the threaded post 11 to drive the telescopic strip 18 to move. A telescopic frame 14 is slidably connected to the outer wall of the telescopic strip 18, providing a sliding trajectory for the telescopic strip 18. The telescopic bar 18 slides within the telescopic frame 14. A fixed post 22 is fixedly connected to the outer wall of the telescopic bar 18, and a limiting plate 21 is fixedly connected to the inner wall of the fixed post 22. The limiting plate 21 is used to limit the movement of the connecting frame 20. During the sliding process of the telescopic bar 18 and the connecting frame 20, the limiting plate 21 fits into a groove on the outer wall of the connecting frame 20, ensuring that the rotating shaft 19, fixedly connected to the connecting frame 20, remains in a state of sliding along the internal trajectory of the telescopic frame 14. When the rotating shaft 19 slides to the rightmost end of the telescopic frame 14, the limiting plate 21... The position plate 21 slides to another groove on the outer wall of the connecting frame 20, causing the rotating shaft 19 to disengage from its movement trajectory and releasing the telescopic bar 18 from its limit. A rotating shaft 23 is fixedly connected to the outer wall of the telescopic bar 18. The outer wall of the limiting plate 21 is attached to the inner wall of the connecting frame 20. The outer wall of the rotating shaft 23 is rotatably connected to the connecting frame 20. A rotating shaft 19 is fixedly connected to the inner wall of the connecting frame 20. A frame 9 is fixedly connected to the outer wall of the telescopic frame 14. The inner wall of the frame 9 is fixedly connected to the outer wall of the support plate 3. A guide plate 8 is fixedly connected to the lower surface of the support plate 3. A rack 16 is fixedly connected to the outer wall of the support 1, and a motor 15 is fixedly connected to the inner wall of the support 1. A gear 17 is fixedly connected to the output end of the motor 15. The gear 17 meshes with the rack 16. The gear 17 meshes with the upper and lower symmetrical racks 16, causing the symmetrical racks 16 to move in opposite directions, which drives the symmetrical support plate 3 to move along the symmetrical guide groove 6 through the symmetrical guide plate 8. This allows the support plate 3 to clamp and fix the light strips of different specifications. A fixing plate 12 is fixedly connected to one end of the threaded column 11.
[0019] Specifically, starting the motor 15 drives the gear 17 to rotate. The gear 17 meshes with the symmetrical racks 16, causing the racks 16 to drive the symmetrical guide plates 8 to move in opposite directions within the guide grooves 6. This, in turn, drives the symmetrical support plates 3 to move synchronously, thus fixing and clamping the plate on which the light strip is placed. At the same time, the threaded post 11 in the support plate 3 drives the fixing plate 12 to adjust its position up and down, fixing the light strip at the upper and lower limits. Pulling the threaded post 11, in conjunction with the spring 10, causes the slider 25 to slide within the slide groove 24. At this time, the threaded post 11 drives the telescopic strip 18 to move. The telescopic strip 18 slides within the telescopic frame 14 via the rotating shaft 19. During this process, the limiting plate 21 always fits against a groove on the outer wall of the connecting frame 20, limiting the connecting frame 20. This ensures that when the sliding stops, the connecting frame 20 can unidirectionally limit the telescopic strip 18 within the telescopic frame 14, thereby fixing the threaded post 11. When the telescopic bar 18 drives the connecting frame 20 to slide to the rightmost side of the telescopic frame 14, the limiting plate 21 on the outer wall of the telescopic bar 18 fits into another groove on the outer wall of the connecting frame 20. At this time, the limiting plate 21 limits the connecting frame 20, causing it to leave the trajectory inside the telescopic frame 14. Pushing it back to the leftmost side of the telescopic frame 14 allows the telescopic frame 14 to once again limit the telescopic bar 18 in one direction.
[0020] Reference Figure 1 - Figure 6 The quick-release assembly includes a connecting rod 28, which is mounted on the outer wall of the support 1. A fixing plate 7 and a fixing plate 3 26 are rotatably connected to the outer wall of the connecting rod 28. The inner walls of fixing plates 7 and 3 26 are fixedly connected to the outer wall of the support 1, providing initial positioning for the connecting rod 28. A clamping plate 27 is fixedly connected to the lower surface of fixing plate 3 26, with its inner wall fitting against the outer wall of the connecting rod 28. The clamping position of clamping plate 27 aligns with the position of the groove at the tail end of the connecting rod 28. Rotating the connecting rod 28 causes its tail end groove to rotate away from the clamping side, thus enabling quick disassembly of the entire assembly and enhancing the equipment's adaptability. The outer wall of fixing column 13 is fixedly connected to... There are two left-right symmetrical sliders 25. The inner wall of the frame 9 has left-right symmetrical sliding grooves 24. The outer wall of the slider 25 is slidably connected to the inner wall of the sliding groove 24. One end of the spring 10 is fixedly connected to the inner wall of the frame 9. The spring 10 is set on the inner wall of the frame 9. The outer wall of the rotating shaft 19 is slidably connected to the inner wall of the telescopic frame 14. The connecting frame 20 is set on the inner wall of the telescopic frame 14. The lower surface of the support plate 3 is attached to the upper surface of the support 1. The upper surface of the support 1 has left-right symmetrical guide grooves 6. The outer wall of the guide plate 8 is slidably connected to the inner wall of the guide groove 6. The outer wall of the guide plate 8 is attached to the inner wall of the support 1. The outer wall of the rack 16 is attached to the inner wall of the support 1. The gear 17 is meshed with the two upper and lower symmetrical racks 16.
[0021] Specifically, the connecting rod 28 is first placed into the symmetrically fitted fixing plate 7 and fixing plate 26. The groove at the end of the connecting rod 28 is limited within the clamping plate 27 fixed on the lower surface of the fixing plate 26 to limit the connecting rod 28. When disassembling, simply twist the connecting rod 28 to rotate the groove at its end to the side that is not clamped, and the connecting rod 28 can be quickly removed, achieving quick disassembly of the whole.
[0022] Working principle: When using an LED light strip testing fixture that requires adjustable clamping, first start the motor 15. The motor 15 drives the gear 17 to rotate. The gear 17 meshes with the symmetrical racks 16, which in turn drive the symmetrical guide plates 8 to move in opposite directions within the guide grooves 6. This allows the symmetrical guide plates 8 to drive the symmetrical support plates 3 to move in the same direction, thus fixing and clamping the plate holding the light strip. At the same time, the threaded post 11 in the support plate 3 drives the fixed plate 12 to adjust its position up and down, thus fixing the light strip at the upper and lower limits. Pulling the threaded post 11, in conjunction with the spring 10, causes the slider 25 to slide within the slide groove 24. During this process, the threaded post 11 drives the telescopic bar 18 to move. The telescopic bar 18 moves through the rotating shaft 1. 9. The telescopic frame 14 slides inside the telescopic frame 14. During the sliding process, the limiting plate 21 is always attached to a groove on the outer wall of the connecting frame 20. The limiting plate 21 limits the connecting frame 20 so that when the sliding stops, the connecting frame 20 can limit the telescopic strip 18 in one direction inside the telescopic frame 14, thereby limiting the telescopic strip 18 to the threaded post 11. The position of the fixing plate 2 12 driven by the threaded post 11 is adjusted and fixed. When the telescopic strip 18 drives the connecting frame 20 to slide to the rightmost side of the telescopic frame 14, the limiting plate 21 on the outer wall of the telescopic strip 18 is attached to another groove on the outer wall of the connecting frame 20. At this time, the limiting plate 21 limits the connecting frame 20 so that it is removed from the track inside the telescopic frame 14, and then pushes it back to the leftmost side of the telescopic frame 14, thereby allowing the telescopic frame 14 to limit the telescopic strip 18 in one direction again. Furthermore, when quickly disassembling an LED light strip testing fixture, first place the connecting rod 28 into the symmetrically fitted fixing plate 7 and fixing plate 3 26. Then, the groove at the end of the connecting rod 28 is limited within the clamping plate 27 fixedly connected to the lower surface of the fixing plate 3 26, thereby limiting the connecting rod 28. When disassembling it, simply rotate the groove at the end of the connecting rod 28 to the side that is not clamped, so that the connecting rod 28 can be quickly disassembled, thus enabling the quick disassembly of the entire fixture.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
