Description

Technical Field

[0001] This utility model relates to the field of test fixture technology, specifically to an RGB lighting test fixture. Background Technology

[0002] With the increasing popularity of mechanical keyboards and gaming keyboards, users' demands for keyboard visual experience are rising. As a core component for achieving colorful lighting effects, the quality and performance of the RGB backlight module directly affect the keyboard's market competitiveness. In the keyboard production process, the lighting test of the RGB backlight module is a crucial step. It requires testing whether the LEDs emit light normally, whether the color display is uniform, and whether there are any short circuits or open circuits in the circuitry, to ensure that the products leaving the factory meet quality standards.

[0003] However, traditional testing methods for keyboard RGB backlight modules have many compatibility issues and are difficult to meet the needs of mass production: the connection cables of keyboard RGB backlight modules vary depending on the keyboard model and design scheme. Traditional testing often relies on manual connection of test lines, which is complicated and inefficient. In addition, keyboard production is mostly batch processing, and traditional test fixtures can usually only test a single backlight module at a time, requiring repeated clamping, powering, and disassembly processes. In large-scale production, this can easily become a bottleneck restricting the efficiency of the production line. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an RGB lighting test fixture, which solves the technical problems of complex testing operations and low efficiency of traditional test fixtures.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an RGB lighting test fixture, including a base, a camshaft rotatably connected to the base through a bearing, one end of the camshaft extending to the outside of the base and fixedly provided with a pressure arm, a handle fixedly provided at the end of the pressure arm, and multiple cams evenly distributed on the camshaft, with a test unit mounted on the base below each of the multiple cams. The test unit includes a base plate that is bolted to the base. Two symmetrically arranged fixing blocks are fixed on the base plate. Pressure blocks are rotatably connected to the two fixing blocks via a rotating shaft. Two sets of springs are installed between the pressure blocks and the base plate. A protrusion is fixed to the bottom of the pressure block, and a test head is detachably installed on the protrusion.

[0006] Preferably, the test head is inserted into the protrusion, and two bolts are threaded onto the side wall of the test head.

[0007] Preferably, a positioning block is fixedly provided at the bottom of the base plate, and the positioning block is inserted into a positioning slot opened on the base.

[0008] Preferably, the base plate has a cable tray.

[0009] Preferably, two limiting blocks are fixedly provided on the side wall of the base near the pressure arm.

[0010] Preferably, an indicator light is fixed on the side wall of the base near the test unit.

[0011] By employing the above technical solution, this utility model provides an RGB lighting test fixture, which has at least the following beneficial effects: 1. This RGB backlight testing fixture, by setting up test units, pushes the connecting cable of the RGB backlight module into the cable slot on the base plate. The spring force on the pressure block makes the test head fit against one end of the connecting cable, thereby performing the lighting test on the RGB backlight module. No connection alignment is required, which has the advantages of simple and convenient testing. In addition, it is equipped with multiple test units, which can test multiple RGB backlight modules at the same time, greatly improving the testing efficiency.

[0012] 2. This RGB lighting test fixture has the advantage of wide applicability because the test head on the protrusion is installed by bolt two. Therefore, different models of RGB backlight modules can be tested by disassembling the test head. Attached Figure Description

[0015] 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.

[0016] The keyboard RGB backlight module is a component that integrates red, green, and blue primary color LED beads and driver circuitry. It is mainly used to provide colorful backlighting effects for products such as mechanical keyboards and gaming keyboards. It is the core hardware for realizing keyboard light color changes and dynamic lighting effects, directly affecting the keyboard's visual experience and user interaction.

[0017] Due to the technical shortcomings of existing technologies, such as complex testing operations and low efficiency, please refer to... Figures 1-4 This embodiment provides an RGB backlight testing fixture, which has the advantages of simple and convenient testing, and can simultaneously test multiple RGB backlight modules, greatly improving testing efficiency. The fixture includes a base 1, and a camshaft 3 is rotatably connected to the base 1 through a bearing 2. One end of the camshaft 3 extends to the outside of the base 1 and is fixedly mounted with a pressure arm 4. A handle 5 is fixedly mounted at the end of the pressure arm 4. Multiple equidistantly distributed cams 6 are fixed on the camshaft 3, and a test unit 7 is mounted on the base 1 below each of the multiple cams 6. In use, the pressure arm 4 is moved down by pulling the handle 5, and the pressure arm 4 drives the cam 6 to rotate through the camshaft 3. The cam 6 squeezes the test unit 7 and opens it. Then, the connection cable of the RGB backlight module is pushed into the cable groove 711 on the base plate 71. Finally, the handle 5 is released, and the test unit 7 can light up the RGB backlight module and perform the test.

[0018] The connection cables for traditional keyboard RGB backlight modules vary depending on the keyboard model and design. Traditional testing often relies on manual connection of the test cables, which is complex and inefficient. To address this issue, please refer to... Figure 3The test unit 7 includes a base plate 71 mounted on the base 1 by bolts 72. Two symmetrically arranged fixing blocks 73 are fixed on the base plate 71. Pressure blocks 75 are rotatably connected to the two fixing blocks 73 by a rotating shaft 74. Two sets of springs 76 are installed between the pressure blocks 75 and the base plate 71. A protrusion 77 is fixed on the bottom of the pressure block 75. A test head 78 is detachably mounted on the protrusion 77. When the pressure block 75 is squeezed by the cam 6, the pressure block 75 will rotate around the rotating shaft 74. At this time, the spring 76 is compressed, and the test head 78 is lifted. Then, the connection cable of the RGB backlight module is pushed into the cable groove 711 on the base plate 71. When the cam 6 stops squeezing the pressure block 75, the pressure block 75 is pushed back to its original position under the elastic force of the spring 76, so that the test head 78 contacts one end of the connection cable, realizing the power-on lighting test.

[0019] Different RGB backlight module models use different connecting cables, and traditional fixtures can only test a single model of RGB backlight module, which has limitations. For this issue, please refer to... Figure 3 The test head 78 is inserted into the protrusion 77, and the side wall of the test head 78 is threaded with a bolt 79. Since the test head 78 on the protrusion 77 is installed by the bolt 79, different models of RGB backlight modules can be tested by disassembling the test head 78, which has the advantage of wide applicability.

[0020] When a single test unit 7 is damaged, it is difficult to ensure that it is installed in the correct position when replacing it. Therefore, a positioning plug 710 is fixed at the bottom of the base plate 71, and the positioning plug 710 is inserted into the positioning slot 10 opened on the base 1. When replacing a single test unit 7, the connection between the positioning plug 710 and the positioning slot 10 can ensure that the test unit 7 can be installed accurately.

[0021] Furthermore, a cable tray 711 is provided on the base plate 71; the cable tray 711 can be used to place the connection cable of the RGB backlight module, which facilitates quick lighting test.

[0022] To prevent the pressure arm 4 from rotating excessively, two limiting blocks 8 are fixed on the side wall of the base 1 near the pressure arm 4; the limiting blocks 8 restrict the rotation area of ​​the pressure arm 4 to prevent the pressure arm 4 from rotating excessively.

[0023] During the lighting test, the test results need to be displayed intuitively. Therefore, an indicator light 9 is fixed on the side wall of the base 1 near the test unit 7. Different indicator lights 9 are used to display the lighting test results so that the testers can understand them more intuitively.

[0024] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
