Description
Technical Field
[0001] This utility model relates to the field of assembly of direct-emitting flat panel lights, and in particular to an LED light strip bonding and positioning fixture. Background Technology
[0002] Adhesive positioning fixtures are specialized tools used to assist in the precise positioning and fixation of workpieces during the bonding process. Through structural design, the position of the workpiece is limited to ensure the positional accuracy and stability during bonding. LED light strips are characterized by their slender structure, dense component arrangement, and frequent bonding and fixation to components such as substrates and housings. Without positioning fixtures, misalignment or skewness can easily occur during bonding, leading to poor circuit connections, uneven light emission, or appearance defects. With the help of adhesive positioning fixtures, the installation position of LED light strips can be precisely defined, ensuring the consistency and reliability of bonding points, while improving assembly efficiency and product yield in mass production.
[0003] The bonding and positioning fixture typically consists of a positioning mechanism, a clamping mechanism, a support mechanism, and a reference component. During use, the positioning mechanism matches the shape of the LED light strip through structures such as grooves and bosses, limiting its position in the X, Y, and Z axis directions. The clamping mechanism uses components such as elastic pressure plates and adjustable pressure blocks to provide uniform pressure without damaging the light strip and prevent displacement during bonding. The support mechanism provides a stable bearing plane for the light strip, avoiding deformation caused by uneven force. The reference component is used to calibrate the overall positioning accuracy of the fixture, ensuring consistency during multi-station production.
[0004] In existing technologies, some LED strip bonding and positioning fixtures employ the following process: the LED strip is placed in a positioning mold, silicone rubber is applied to the back of an aluminum substrate using a glue applicator, and then the base is inverted onto the mold to precisely fit the LED strip into the center of the groove on the base. However, this method has limitations. During assembly, the positioning mold needs to be customized based on the number of LED beads in the LED strip and the distribution spacing of each group of strips on the base. When faced with a wide variety of products, small production batches, and differences in the number of LED beads in the strips and the spacing between groups, a large number of positioning molds of different specifications need to be customized. This not only leads to a complex variety of positioning molds and a significant increase in initial investment costs, but also poses challenges to cost control and production management in the early stages of production. Therefore, an LED strip bonding and positioning fixture is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an LED light strip bonding and positioning fixture, which aims to improve the problem that in the existing technology, when traditional LED light strips are bonded to the chassis, the positioning mold needs to be customized. In scenarios with a wide variety of products and small production batches, this can easily lead to an excessive number of positioning molds required and high initial capital investment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An LED light strip bonding and positioning fixture includes a lower base, with multiple supports slidably connected to the top of the lower base. Fixing frames are detachably connected to both the left and right sides of each support. An adjustment mechanism is installed on the outside of each fixing frame, and a limit mechanism is installed inside each fixing frame. The adjustment mechanism includes a slide rail, the outer wall of which is fixedly connected to the outer wall of the fixed frame. The outer walls of both slide rails are detachably connected with quick-release bolts. The outer walls of the quick-release bolts are threaded with wing nuts. The outer walls of the slide rails are threaded with fixing bolts. A support assembly is provided on the outside of the lower chassis. As a further description of the above technical solution: The support component includes a lower frame, the inner wall of which is fixedly connected to the outer wall of the lower chassis, and an upper frame is fixedly connected to the top of the lower frame. As a further description of the above technical solution: The limiting mechanism includes multiple support plates, the outer walls of which are fixedly connected to the inner wall of the fixed frame. A damper is fixedly connected to the outer wall of each support plate, and a push block is fixedly connected to the other end of the damper. A limiting block is slidably connected to the outer walls of two push blocks. As a further description of the above technical solution: The inner wall of the fixed frame is fixedly connected with multiple limiting blocks, and the damper is sleeved with a spring. As a further description of the above technical solution: One end of the spring is fixedly connected to the outer wall of the support plate, and the other end of the spring is fixedly connected to the outer wall of the push block; As a further description of the above technical solution: The outer wall of the first limiting block is slidably connected to the outer walls of the two second limiting blocks, and the outer walls of the plurality of pushing blocks are slidably connected to the inner wall of the fixed frame. As a further description of the above technical solution: The outer wall of the support is provided with multiple limiting grooves, and the outer wall of the limiting block is slidably connected to the outer wall of the limiting groove; As a further description of the above technical solution: The outer wall of the fixing bolt is threaded to the inner wall of the fixing frame, and the outer wall of the slide rail is provided with multiple slots.
[0007] This utility model has the following beneficial effects: 1. In this utility model, by adjusting the cooperation between the wing nut and the quick-release bolt in the adjustment mechanism, the slide rail and the fixed frame are controlled to slide, thereby achieving the effect of flexibly adjusting the spacing of the support body according to the specifications of the LED light strip, effectively reducing the number of positioning molds required and reducing the initial investment cost.
[0008] 2. In this utility model, in the limiting mechanism, the spring and the damper work together to make the limiting block one accurately snap into the limiting groove of the support body. When it is necessary to replace the support body with a different appearance, the limiting block one uses the spring force and the damper to buffer and provide stable limiting for the inserted new support body. This ensures the consistency of the bonding point of the support body when the tooling is adapted to support bodies of different specifications, thereby improving product quality and production efficiency.

Detailed Implementation
[0011] 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.
[0012] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an LED light strip bonding and positioning fixture, including a lower base plate 1. The lower base plate 1 serves as the basic support structure of the fixture and is located at the bottom of the fixture, playing the role of supporting and fixing all the support bodies 2. Multiple support bodies 2 are slidably connected to the top of the lower base plate 1. The lower base plate 1 provides the installation foundation for the support bodies 2 and ensures the stability of the entire fixture. Fixing frames 3 are detachably connected to both sides of the support bodies 2. The fixing frames 3 can be adjusted to a specified position according to actual needs and then tightened to prevent the support bodies 2 from shaking. An adjustment mechanism 4 is installed on the outside of the fixing frame 3. The adjustment mechanism 4 is used to adjust the position of the fixing frame 3 to adapt to the positioning requirements of LED light strips of different specifications. A limiting mechanism 5 is installed inside the fixing frame 3. The limiting mechanism 5 limits and fixes the support bodies 2 to ensure accurate positioning during the bonding process. The adjusting mechanism 4 includes a slide rail 41, which is fixed to the outer wall of the fixed frame 3, providing an installation position for components such as the quick-release bolt 42. The slide rail 41, in conjunction with the quick-release bolt 42 and the wing nut 43, adjusts the position of the fixed frame 3. The outer wall of the slide rail 41 is fixedly connected to the outer wall of the fixed frame 3, ensuring a stable connection between the slide rail 41 and the fixed frame 3 and guaranteeing the normal operation of the adjusting mechanism 4. Both slide rails 41 have quick-release bolts 42 detachably connected to their outer walls, which, in conjunction with the wing nut 43, allow the fixed frame 3 to be adjusted by loosening or tightening. The quick-release bolt 42 is threaded with a wing nut 43 on its outer wall, which can be manually tightened by the operator to adjust the tightness of the quick-release bolt 42 and the slide rail 41, making it easy to adjust the position of the fixed frame 3. The slide rail 41 is threaded with a fixing bolt 44 to fix the slide rail 41 to the fixed frame 3, ensuring the stability of the structure after adjustment and preventing the slide rail 41 from detaching from the fixed frame 3. The lower chassis 1 is provided with a support component 45 on its exterior, which provides additional support for the entire tooling and enhances stability.
[0013] Reference Figures 2 to 4 The support component 45 includes a lower frame 451, which serves as the bottom support structure of the support component 45 and together with the upper frame 452 forms a frame, providing an adhesive positioning base for the support body 2. The inner wall of the lower frame 451 is fixedly connected to the outer wall of the lower chassis 1, so that the lower frame 451 and the lower chassis 1 form a stable connection, enhancing the overall support strength of the tooling. The top of the lower frame 451 is fixedly connected to the upper frame 452, and the upper frame 452 and the lower frame 451 form a support frame.
[0014] Reference Figures 3 to 5The limiting mechanism 5 includes multiple support plates 51. When it is necessary to replace the support body 2 with one that meets different appearance requirements, the limiting mechanism 5 can provide stable limiting after the support body 2 is installed. The support plates 51 are fixed to the inner wall of the fixed frame 3. The support plates 51 are used to install the damper 52 and provide a fixed support point for the damper 52. The outer walls of the multiple support plates 51 are all fixedly connected to the inner wall of the fixed frame 3 to ensure that the multiple support plates 51 are stably installed in the fixed frame 3 and to provide support for components such as the damper 52. The outer walls of the support plates 51 are fixedly connected to the damper 52. 2. When the push block 53 moves, the movement is buffered by the internal medium damping effect, reducing vibration and making the limiting process smoother. The other end of the damper 52 is fixedly connected to the push block 53, which is connected to the damper 52 and the spring 55. Under the action of the damper 52 and the spring 55, it can slide in the fixed frame 3. Pushing the limiting block 54 can limit or release the support body 2. The outer walls of the two push blocks 53 are slidably connected to the limiting block 54. The movement of the push block 53 drives the movement of the limiting block 54 to achieve the limiting and fixing of the support body 2. Multiple limiting blocks 56 are fixedly connected to the inner wall of the fixed frame 3. The limiting blocks 56 restrict the sliding direction and range of the limiting block 54, ensuring that the limiting block 54 slides smoothly within the fixed frame 3 and ensuring the accuracy of the limiting. A spring 55 is sleeved on the outside of the damper 52. When the push block 53 moves, it stores or releases elastic force to push the push block 53 to reset. In conjunction with the damper 52, the push block 53 moves more smoothly. One end of the spring 55 is fixedly connected to the outer wall of the support plate 51. Fixing one end of the spring 55 allows it to stably apply elastic force to the push block 53. The other end of the spring 55 is fixedly connected to the outer wall of the push block 53. The elastic force pushes the push block 53 to reset, ensuring the normal operation of the limiting mechanism 5. The outer wall of the limiting block 54 is slidably connected to the outer walls of the two limiting blocks 56. Under the restriction of the limiting blocks 56, the limiting block 54 can only slide in the horizontal direction, thereby achieving the precise limiting of the limiting block 54 on the support body 2. The outer walls of multiple pushing blocks 53 are slidably connected to the inner wall of the fixed frame 3, allowing them to slide smoothly within the fixed frame 3 and ensuring that the pushing blocks 53 can properly push the limiting block 54. The outer wall of the support body 2 has multiple limiting grooves 6, which cooperate with the limiting block 54 to limit the fixed frame 3 and prevent the fixed frame 3 from shaking on the support body 2. The outer wall of the limiting block 54 is slidably connected to the outer wall of the limiting groove 6. After being inserted into the limiting groove 6, it restricts the position of the fixed frame 3 and ensures the stability of the tooling structure. The outer wall of the fixing bolt 44 is threadedly connected to the inner wall of the fixed frame 3 to fix the slide rail 41 on the fixed frame 3, ensuring that the adjustment mechanism 4 is firmly connected to the fixed frame 3. The outer wall of the slide rail 41 has multiple slots 7, which cooperate with the quick-release bolt 42. The quick-release bolt 42 can be inserted into different slots 7 to adjust the position of the fixed frame 3 on the slide rail 41, thereby adjusting the spacing of the support body 2.
[0015] Working principle: First, loosen the wing nut 43 to loosen the connection between the quick-release bolt 42 and the slide rail 41. Then, pull the quick-release bolt 42 out of the slide rail 41. At this time, the two adjacent slide rails 41 can slide freely relative to each other, and the fixed frame 3 will also move synchronously with the slide rail 41. By sliding the fixed frame 3 and the slide rail 41, the distance between the support body 2 can be adjusted. After the distance is adjusted to a suitable position that meets the specifications of the LED light strip, reinsert the quick-release bolt 42 along the slot 7 into the slide rail 41, and then tighten the wing nut 43. The wing nut 43 and the quick-release bolt 42 are fixed to each other by threads, thereby completing the fastening of the fixed frame 3. This achieves the purpose of flexibly adjusting the distance of the support body 2 according to the specifications of the LED light strip, effectively reducing the number of positioning molds required.
[0016] When installing the support body 2, as the support body 2 is pushed down along the outer wall of the fixed frame 3, the support body 2 first squeezes the outer wall of the limiting block 54, forcing the limiting block 54 to slide into the fixed frame 3. One end of the limiting block 54 has inclined surfaces distributed on its upper and lower sides, each inclined surface corresponding to a pushing block 53. When the limiting block 54 slides, its two inclined surfaces will simultaneously squeeze the two pushing blocks 53, causing the pushing blocks 53 to slide along the inclined surfaces in a direction away from each other. The movement of the pushing blocks 53 causes the spring 55 and the damper 52 to be compressed. The spring 55 stores elastic force along the movement direction of the pushing block 53, while the damper 52 buffers the compression impact force through the flow of internal medium. When the limiting block 54 is aligned with the limiting groove 6 of the support body 2, the spring 55 releases its elastic force, pushing the limiting block 54 into the limiting groove 6. At the same time, in conjunction with the damping effect of the damper 52, a stable limit is formed on the support body 2, effectively preventing the support body 2 from shaking.
[0017] When it is necessary to quickly replace or disassemble the support body 2, lift the support body 2 upwards. The inner wall of the limiting groove 6 applies force to the limiting block 54, causing the limiting block 54 to slide along the inclined plane and squeeze the pushing block 53. The pushing block 53 drives the spring 55 to compress and store energy. The pushing block 53 drives the damper 52 to buffer. After the limiting block 54 has completely slid out of the limiting groove 6, the fixing frame 3 and the support body 2 are released from the limiting, and the disassembly of the support body 2 can be completed so that the support body 2 with different appearance can be replaced.
[0018] 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.
