Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated testing equipment technology, and in particular to a keyboard LED light testing device. Background Technology
[0002] With the development of computer keyboard backlight modules, computer keyboard backlight modules now integrate LED lights. To meet the requirements of keyboard use at night, the keyboard keys need to be laser-etched into backlit keys, meaning that the display part on each key can transmit light, allowing the light from below the keyboard to shine through, so that users can clearly distinguish each key and avoid accidental operation.
[0003] Currently, the production process simply involves manually inspecting each key on the keyboard to ensure it transmits light; keys that do are labeled as good and released for sale. However, as users demand higher standards for keyboards and their usage environments, more precise requirements are placed on the lumen output of the keyboard backlight. Yet, lumen output cannot be measured manually. Therefore, an effective solution for testing keyboard backlight lumen output is urgently needed. Summary of the Invention
[0004] The purpose of this invention is to provide a keyboard LED light detection device that can automatically detect the lumens of keyboard key lights, addressing the shortcomings of existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] This utility model provides a keyboard LED light testing device, which includes a machine base, a material carrier fixture movably mounted on the machine base, a dark box mounted on the machine base, a light lumen testing device mounted on the machine base and located inside the dark box, and a fixture moving drive device mounted on the machine base for driving the material carrier fixture to move into or out of the dark box. The light lumen testing device includes a movable plate movably mounted on the machine base, a light shield connected to the movable plate, a detection probe mounted on the light shield, and an illuminance meter mounted on the machine base; the detection probe passes through the light shield and is electrically connected to the illuminance meter.
[0007] Furthermore, the machine tool is equipped with a detection movement drive device for driving the moving plate to move along the X-axis and Z-axis of the machine tool.
[0008] Furthermore, the detection moving drive device includes a gantry frame mounted on the machine base, an X-axis linear drive module mounted on the crossbeam of the gantry frame, and a Z-axis linear drive module mounted on the X-axis linear drive module. The Z-axis linear drive module is connected to the sliding block of the X-axis linear drive module, and the moving plate is connected to the sliding block of the Z-axis linear drive module.
[0009] Furthermore, the light-shielding plate is arranged parallel to the material-carrying fixture, and fixed ribs are respectively provided on both sides of the movable plate. The top of the fixed ribs is connected to the movable plate, and the bottom of the fixed ribs is connected to the light-shielding plate.
[0010] Furthermore, the gantry frame is also equipped with a fixing frame, which has a first fixing groove and a second fixing groove.
[0011] Furthermore, the fixture moving drive device includes a Y-axis linear drive module mounted on the machine base, two guide rails respectively mounted on both sides of the Y-axis linear drive module, and sliders that slide in cooperation with the guide rails. The slider of the Y-axis linear drive module is connected to the material-carrying fixture, and both sides of the material-carrying fixture are respectively connected to the sliders on the two guide rails.
[0012] The beneficial effects of this utility model are:
[0013] This invention provides a keyboard LED light testing device. A loading fixture delivers the keyboard into a dark chamber, simulating the keyboard's use in a dark environment.

Detailed Implementation
[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.
[0023] like Figures 1 to 6 As shown, this utility model provides a keyboard LED light testing device, which includes a machine base 1, a material carrier 2 movably mounted on the machine base 1, a dark box 3 mounted on the machine base 1, a light lumen detection device mounted on the machine base 1 and located inside the dark box 3, and a fixture movement drive device 4 mounted on the machine base 1 for driving the material carrier 2 to move into or out of the dark box 3. The light lumen detection device includes a movable plate 11 movably mounted on the machine base 1, a light shield 12 connected to the movable plate 11, a detection probe 13 mounted on the light shield 12, and an illuminance meter 14 mounted on the machine base 1; the detection probe 13 penetrates the light shield 12, and the detection probe 13 is electrically connected to the illuminance meter 14. Specifically, the illuminance meter 14 is an instrument specifically used to measure luminance and brightness. The fixture movement drive device 4 is used to drive the material carrier 2 to move into or out of the dark box 3.
[0024] In practical applications, the keyboard to be tested is placed and fixed on the carrier fixture 2. Then, the fixture moving drive device 4 drives the carrier fixture 2 to move, moving the keyboard to be tested into the dark box 3, until the keyboard is moved to the detection position of the light lumen detection device. Next, the moving plate 11 moves and drives the light shield 12 to cover the keyboard on the carrier fixture 2, aligning the detection surface of the detection probe 13 on the light shield 12 (i.e., the bottom surface of the light shield 12) with the key to be tested. Finally, the keyboard is powered on, and the lights on the keys are turned on. At this time, the detection probe 13 detects the lumen of light transmitted by the key and transmits the data to the illuminance meter 14 for analysis, thereby determining whether the light transmission lumen of the keyboard key meets the production standard. After one test is completed, the moving plate 11 drives the light shield 12 to the next position to test the light transmission of other keys.
[0025] In this technical solution, the dark box 3 provides a relatively dark environment for the keyboard, simulating the keyboard's use in a dark environment and avoiding unnecessary external light from causing significant errors in the detection. The light shield 12 is used to block light from other keys in non-detection states, preventing interference with the keys being detected.
[0026] This invention uses a material carrier fixture 2 to deliver the keyboard into a dark chamber 3. The environment inside the dark chamber 3 simulates the keyboard's use in a dark environment. Then, an illuminance meter 14, in conjunction with a detection probe 13, detects and analyzes the lumens of light transmitted through the keyboard keys to determine if they meet production standards. The entire process is completed using an automated moving mechanism and professional testing instruments, eliminating the need for manual operation and solving the problem of the inability to detect light lumens with the naked eye, effectively improving testing efficiency and accuracy.
[0027] In this technical solution, the machine tool 1 is equipped with a detection movement drive device 5 for driving the moving plate 11 to move along the X-axis and Z-axis directions of the machine tool 1. The detection movement drive device 5 includes a gantry frame 51 mounted on the machine tool 1, an X-axis linear drive module 52 mounted on the crossbeam of the gantry frame 51, and a Z-axis linear drive module 53 mounted on the X-axis linear drive module 52. The Z-axis linear drive module 53 is connected to the sliding block of the X-axis linear drive module 52, and the moving plate 11 is connected to the sliding block of the Z-axis linear drive module 53.
[0028] In practical applications, the detection drive device 5 can drive the moving plate 11 to move along the X-axis and Z-axis directions on the machine base 1, that is, to move laterally and vertically. The vertical movement of the moving plate 11 is used to lower the light shield 12 to cover the keyboard and to move the light shield 12 away from the keyboard. The horizontal movement of the moving plate 11 is used to move the detection probe 13 on the light shield 12 to the position corresponding to other keyboard keys, so that the detection probe 13 can detect the keys.
[0029] In this technical solution, the light-shielding plate 12 is arranged parallel to the material-carrying fixture 2. Fixed ribs 54 are respectively provided on both sides of the moving plate 11. The top of the fixed ribs 54 is connected to the moving plate 11, and the bottom of the fixed ribs 54 is connected to the light-shielding plate 12. The bottom of the fixed ribs 54 has a triangular design. This structural design ensures that the light-shielding plate 12 and the material-carrying fixture 2 remain parallel at all times, and also enhances the support strength of the light-shielding plate 12, ensuring more precise movement of the light-shielding plate 12.
[0030] In this technical solution, the gantry frame 51 is further provided with a fixing frame 55, which has a first fixing slot 551 and a second fixing slot 552. The first fixing slot 551 is used to place the probe adapter, which is electrically connected to the detection probe 13. The second fixing slot 552 is used to place the illuminance meter 14, which is electrically connected to the probe adapter. This structure is designed to facilitate the storage of the detection instruments, making the overall structure of the equipment simpler and more compact.
[0031] In this technical solution, the fixture moving drive device 4 includes a Y-axis linear drive module 41 mounted on the machine base 1, two guide rails 42 respectively mounted on both sides of the Y-axis linear drive module 41, and a slider 43 that slides in cooperation with the guide rails 42. The slider of the Y-axis linear drive module 41 is connected to the material-carrying fixture 2, and both sides of the material-carrying fixture 2 are respectively connected to the sliders 43 on the two guide rails 42. This structure is simple and compact in design. Through the cooperation of the Y-axis linear drive module 41, the guide rails 42, and the sliders 43, the movement of the material-carrying fixture 2 can be more stable and reliable, and the movement position can be more precise.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
