Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED light detection technology, and in particular to a fixing bracket for LED light detection. Background Technology
[0002] The LED lamp bead light testing fixture is an auxiliary device specifically designed for testing the optical performance of LED lamp beads. Its core function is to fix the position of the lamp beads through a mechanical structure, ensuring that the light emission angle and position of the lamp beads remain stable during the testing process, thereby making the test data of optical parameters such as light intensity, color temperature, and wavelength more accurate and reliable.
[0003] However, in the existing technology, most existing fixtures adopt "customized clamping structures", which can only be adapted to LED beads of specific package sizes. They lack universality for other packages or irregularly shaped beads. The clamps used for 5050 beads cannot clamp the smaller 0805 beads because the opening size is fixed, which means that the entire fixture needs to be replaced when the production line changes the type of beads. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fixing bracket for testing LED beads.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fixing bracket for detecting LED light beads, comprising a fixing bracket body, and further comprising:
[0006] A clamping range adjustment assembly includes a sliding plate connected to a fixed frame body, an adjustment block connected to the sliding plate, a fixed plate slidably connected to the adjustment block, a rocker arm slidably connected to the fixed plate, a transmission block slidably connected to the rocker arm, the rocker arm being rotatably connected to the fixed frame body, a transmission rod slidably connected to the transmission block, and a transmission assembly connected to the transmission block.
[0007] In a preferred embodiment, the transmission assembly includes a fixed frame fixedly connected to the fixed frame body, a crossbar slidably connected to the fixed frame, and a disc slidably connected to the crossbar.
[0008] Using the above technical solution: when the crossbar is displaced during use, the disc can be rotated, causing the fixed rod on the disc to move the sliding rod, thus changing the position of the sliding rod when it contacts the LED.
[0009] In a preferred embodiment, a fixed rod is rotatably connected to the crossbar, the fixed rod is fixedly connected to the bottom of the disc, a spring is fixedly connected to the bottom of the fixed rod, and a sliding rod is fixedly connected to the bottom of the spring.
[0010] The above technical solution utilizes a spring to make the connection between the sliding rod and the fixed rod more flexible.
[0011] In a preferred embodiment, universal joints are fixedly connected to both ends of the sliding plate. The side of the universal joint away from the sliding plate is fixedly connected to the fixed frame body, and the side of the universal joint near the fixed plate is fixedly connected to the fixed plate.
[0012] The above technical solution, by incorporating universal joints, makes the connection between the sliding plate, the fixed frame body, and the fixed plate more flexible.
[0013] In a preferred embodiment, a slot is provided on the side of the fixing frame body near the fixing plate, and the fixing plate is slidably connected in the slot on the fixing frame body.
[0014] The above technical solution is adopted: by setting a slot, the sliding of the fixed plate is limited when the fixed plate slides in the slot.
[0015] In a preferred embodiment, the rocker arm is rotatably connected to the fixed frame body via a pivot.
[0016] The above technical solution is adopted: by setting a rotating shaft, the rocker arm can rotate more flexibly within the transmission block, making it easier for the rocker arm to slide the fixed plate up and down.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0018] When this utility model uses a fixed frame to expand the clamping range of the fixed plate, the crossbar is moved inward, causing the transmission rod to shift. The transmission rod slides in the inclined groove of the transmission block. With the help of the inclined plane transmission principle, the transmission block slides downward in the slot of the fixed frame body. The downward movement of the transmission block presses down on the near side of the rocker arm with the lever principle, causing the far side of the rocker arm to lift up. The lifted rocker arm lifts the fixed plate through the linkage transmission. The fixed plate drives the adjusting block to move upward. Finally, the sliding plate pushes the adjusting block to slide out of the fixed plate, completing the expansion of the clamping range. By moving the adjusting block, the sliding plate, rocker arm and other components are linked together, and the clamping range can be flexibly adjusted. There is no need to replace the entire clamp, so it can be compatible with LED beads of different sizes and package types. This solves the problem in the prior art that the existing technology cannot clamp the smaller 0805 LED beads. Attached Figure Description

[0028] 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.
[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a fixing bracket for LED lamp bead light detection, including a fixing bracket body 1, and further including:
[0030] The clamping range adjustment assembly 2 includes a sliding plate 27 connected to the fixed frame body 1, an adjustment block 26 connected to the sliding plate 27, a fixed plate 25 slidably connected to the adjustment block 26, a rocker arm 23 slidably connected to the fixed plate 25, a transmission block 21 slidably connected to the rocker arm 23, the rocker arm 23 being rotatably connected to the fixed frame body 1, a transmission rod 22 slidably connected to the transmission block 21, and a transmission assembly 3 connected to the transmission block 21.
[0031] When this utility model uses the fixing frame to expand the clamping range of the fixing plate 25, the horizontal bar 31 is moved inward, which drives the transmission rod 22 to move. The transmission rod 22 slides in the inclined groove of the transmission block 21. With the help of the inclined plane transmission principle, the transmission block 21 slides downward in the slot of the fixing frame body 1. The downward movement of the transmission block 21 presses down on the near side of the rocker arm 23 by lever principle, causing the far side of the rocker arm 23 to lift up. The lifted rocker arm 23 lifts the fixing plate 25 through the linkage transmission. The fixing plate 25 drives the adjusting block 26 to move up. Finally, the sliding plate 27 pushes the adjusting block 26 to slide out of the fixing plate 25, thus completing the expansion of the clamping range. By moving the adjusting block 26, the sliding plate 27, the rocker arm 23 and other components are linked together to realize the flexible adjustment of the clamping range. Without replacing the whole fixture, it can be compatible with LED lamp beads of different sizes and package types, solving the problem that the prior art cannot clamp the smaller 0805 lamp beads.
[0032] like Figures 2 to 3 As shown, the transmission assembly 3 includes a fixed frame 33 fixedly connected to the fixed frame body 1. A crossbar 31 is slidably connected to the fixed frame 33, and a disk 32 is slidably connected to the crossbar 31. The disk 32 is driven to rotate by the linear displacement of the crossbar 31. By using the conversion mechanism between circular motion and linear motion, the horizontal motion of the crossbar 31 is converted into the displacement of the sliding rod 29, so as to realize the fine control of the contact position between the sliding rod 29 and the lamp bead, and ensure the accuracy and consistency of the lamp bead positioning during the detection process.
[0033] like Figures 4 to 5 As shown, a fixed rod 211 is rotatably connected to the crossbar 31. The fixed rod 211 is fixedly connected to the bottom of the disc 32. A spring 210 is fixedly connected to the bottom of the fixed rod 211. A sliding rod 29 is fixedly connected to the bottom of the spring 210. The adaptive deformation characteristics of the spring 210 can adapt to LED beads of different sizes and surface shapes, enhancing the fit and stability during clamping.
[0034] like Figure 5 As shown, universal joints 28 are fixedly connected to both ends of the sliding plate 27. The side of the universal joint 28 away from the sliding plate 27 is fixedly connected to the fixed frame body 1, and the side of the universal joint 28 near the fixed plate 25 is fixedly connected to the fixed plate 25. The multi-degree-of-freedom connection characteristics of the universal joint 28 eliminate motion interference in mechanical transmission. When adjusting the clamping range, it ensures that all components move in coordination, thereby improving the overall transmission efficiency and smooth operation of the structure.
[0035] like Figure 1 as well as Figure 5As shown, a slot is provided on the side of the fixed frame body 1 near the fixed plate 25. The fixed plate 25 is slidably connected in the slot on the fixed frame body 1. The slot forms a mechanical limiting guide for the fixed plate 25, strictly constraining its sliding trajectory, preventing deviation or shaking during the adjustment process, providing a reliable support benchmark for lamp bead detection, and improving the accuracy of the detection data.
[0036] like Figure 1 , Figure 3 , Figure 4 As shown, the rocker arm 23 is rotatably connected to the fixed frame body 1 via a rotating shaft 24. The rotating shaft 24 allows the rocker arm 23 to rotate more flexibly within the transmission block 21, facilitating the rocker arm 23 to move the fixed plate 25 up and down.
[0037] Working principle:
[0038] like Figure 1-5 As shown, when it is necessary to fix small LED beads and increase the clamping range on the fixing plate 25, the operator only needs to move the crossbar 31 to clamp inward, causing the transmission rod 22 to be displaced and slide in the inclined groove on the transmission block 21. This causes the transmission block 21 to slide downward in the corresponding slot on the fixing frame body 1, causing the side of the rocker arm 23 near the transmission block 21 to be pressed down and slide, and the side of the rocker arm 23 away from the transmission block 21 to be lifted. This causes the fixing plate 25 to be lifted, which in turn causes the fixing plate 25 to move the adjusting block 26 upward, causing the sliding plate 27 to move the adjusting block 26 out of the fixing plate 25, thereby expanding the clamping range.
[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
