Description

Technical Field

[0001] This utility model relates to the field of optical testing technology, and in particular to a device for testing the LED function of wearable electronic products. Background Technology

[0002] With the widespread adoption of smart wearable devices such as smartwatches, smart bands, and TWS earphones, the functionality and reliability of their integrated LED indicator lights have become one of the key indicators for measuring product quality. These LED lights bear important functions such as displaying battery level, connection status, and notification reminders. Therefore, it is an essential process to conduct 100% testing of the brightness, color, and blinking mode of LEDs during the manufacturing process.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: Traditional manual visual inspection methods are inefficient, labor-intensive, and prone to misjudgment and missed detection due to the subjective fatigue of the inspectors. Some automated inspection solutions are mostly conducted in open environments, which are easily affected by changes in ambient light in the workshop, resulting in unstable inspection results and poor reliability. Common conveying and positioning mechanisms lack collaborative design with the closed inspection environment. After the product is transported, it often needs to undergo multiple and complex positional adjustments before entering the inspection station. The process is cumbersome, which seriously restricts the overall inspection cycle and makes it impossible to achieve efficient, seamless integrated assembly line operations.

[0004] To address these issues, we provide a device for testing the LED function of wearable electronic products. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology is easily affected by external environmental interference during testing. To address this, we propose a test device for LED function of wearable electronic products.

[0006] To achieve the above objectives, this application adopts the following technical solution: a test device for LED function of wearable electronic products, including a workbench with a transport groove on its surface; an environmental component is provided on the surface of the workbench, the environmental component including a black box fixedly connected to the top of the workbench, a light-blocking curtain fixedly connected to one side of the black box, and a detector fixedly connected to the top of the inner cavity of the black box, the environmental component being used to create an environment most suitable for testing LED function; a transport component is provided on the surface of the workbench, the transport component including a first rotating shaft rotatably connected to the inner cavity of the transport groove, a second rotating shaft rotatably connected to the inner cavity of the transport groove, and a transport belt slidably connected to the surfaces of the first rotating shaft and the second rotating shaft, the transport component being used to transport the wearable electronic product to the inner cavity of the black box.

[0007] Preferably, the workbench surface is provided with a lifting groove, and a first cylinder is fixedly connected to the inner cavity of the lifting groove.

[0008] Preferably, a lifting block is fixedly connected to the output end of the first cylinder, and the lifting block is used to raise the wearable electronic product into the black box.

[0009] Preferably, a clamping groove is provided around the inner cavity of the black box, and a second cylinder is fixedly connected to the inner cavity of the clamping groove.

[0010] Preferably, a clamping block is fixedly connected to the output end of the second cylinder, and the clamping block is used to clamp wearable electronic products on the lifting platform.

[0011] Preferably, a slanted slider is fixedly connected to the surface of the workbench, and a light strip is provided around the top of the inner cavity of the black box.

[0012] Preferably, a motor is fixedly connected to the surface of the transport trough, and the output end of the motor is fixedly connected to one end of the first rotating shaft.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model constructs a stable, reliable, and efficient dedicated testing environment through improved environmental components. By fixing a closed black box on the top of the workbench and installing a light-blocking curtain at its entrance, this design fundamentally eliminates interference from external ambient light, such as the swaying of workshop ceiling lights or shadows caused by personnel movement, creating an ideal "dark room" environment for LED optical testing. This physical light-blocking method is more thorough, lower in cost, and extremely reliable than software algorithm compensation, ensuring the consistency of image acquisition conditions. In addition, the detector is fixed to the top of the inner cavity of the black box, and its position remains unchanged once set, avoiding the need for refocusing and repositioning for each test. This not only improves the detection accuracy but also significantly increases the detection efficiency. This integrated environmental design transforms uncontrollable open testing into controllable closed testing, which is a key technical solution to ensure the accuracy and repeatability of test results.

[0014] 2. This utility model greatly improves the overall testing efficiency through improved transportation components, integrating the loading and unloading process with the closed testing process to form a highly efficient "tunnel-type" testing production line. After the product to be tested is placed outside the box, it is carried by the conveyor belt and enters the black box in sequence through the inclined slider and the light-blocking curtain. The lifting groove and the first cylinder structure are responsible for precise positioning in the vertical direction. This division of labor mode of "production line transmission + positioning and lifting" has the dual advantages of high-speed transportation and precise positioning. While ensuring that the product is accurately delivered to the testing station, it perfectly meets the rhythm requirements of the high-speed production line. Attached Figure Description

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Example 1 Please see Figures 1-4 This utility model is a device for testing the LED function of wearable electronic products. It includes a workbench 1, a transport groove 2 on the surface of the workbench 1, and an environmental component on the surface of the workbench 1. The environmental component includes a black box 3 fixedly connected to the top of the workbench 1, a light-blocking curtain 4 fixedly connected to one side of the black box 3, and a detector 5 fixedly connected to the top of the inner cavity of the black box 3. The environmental component is used to create the most suitable environment for testing the LED function. The surface of the workbench 1 is provided with a transport component, which includes a first rotating shaft 6 rotatably connected to the inner cavity of the transport groove 2, a second rotating shaft 7 rotatably connected to the inner cavity of the transport groove 2, and a transport belt 8 slidably connected to the surfaces of the first rotating shaft 6 and the second rotating shaft 7. The transport component is used to transport the wearable electronic product to the inner cavity of the black box 3.

[0022] Specifically: Black box 3 is a sealed enclosure with openings on one side and bottom. Its inner walls are lined with matte black light-absorbing material to minimize internal light reflection. A light-blocking curtain 4, composed of multiple overlapping layers of flexible black material, is suspended at the entrance of black box 3, forming a barrier that allows the product to pass through while effectively blocking external light intrusion. Detector 5, fixed to the center of the top of the inner cavity of black box 3, is a high-resolution industrial camera equipped with an LED strip 16, used to provide stable and uniform illumination for the product under test and to acquire clear images. The first rotating shaft 6 and the second rotating shaft 7 drive a conveyor belt to deliver wearable electronic products into black box 3.

[0023] Example 2 Please see Figures 1-4 Based on embodiment 1, a lifting groove 9 is provided on the surface of the workbench 1. A first cylinder 10 is fixedly connected to the inner cavity of the lifting groove 9. A lifting block 11 is fixedly connected to the output end of the first cylinder 10. The lifting block 11 is used to lift wearable electronic products into the black box 3. A clamping groove 12 is provided around the inner cavity of the black box 3. A second cylinder 13 is fixedly connected to the inner cavity of the clamping groove 12. A clamping block 14 is fixedly connected to the output end of the second cylinder 13. The clamping block 14 is used to clamp the wearable electronic products on the lifting platform. A slanted slider 15 is fixedly connected to the surface of the workbench 1. A light strip 16 is provided around the top of the inner cavity of the black box 3. A motor 17 is fixedly connected to the surface of the transport groove 2. The output end of the motor 17 is fixedly connected to one end of the first rotating shaft 6.

[0024] Specifically: Motor 17 drives the first rotating shaft 6 to rotate, thereby driving the conveyor belt 8 to circulate. The operator places the wearable electronic product to be tested at the entrance end of the conveyor belt 8. The product is sent into the inclined slider 15 along with the conveyor belt 8, and then passes through the light-blocking curtain 4 into the detection station inside the black box 3. The output end of the first cylinder 10 pushes the lifting block 11 to rise, steadily lifting the product on the conveyor belt 8 to a preset precise detection height. The second cylinder 13 pushes the clamping blocks 14 in four directions to move synchronously towards the center, gently and firmly clamping the product from all sides to ensure that the product is completely fixed during the detection process. The light strip 16 is used to provide the best detection lighting conditions. The camera of the detector 5 quickly acquires images of the indicator lights on the surface of the product.

[0025] Working principle: The user starts the equipment through the external control system. The product to be tested is automatically conveyed by the conveyor belt 8, passes through the light-blocking curtain 4 via the inclined slider 15, and enters the detection station inside the black box 3. The first cylinder 10 sends the product to the preset detection height through the lifting block 11. The second cylinder 13 drives the clamping block 14 to accurately position and fasten the product from all sides to ensure that it does not move during the detection process. Then, the light strip 16 inside the black box 3 is lit to provide the optimal lighting environment for the camera to take pictures. At the same time, the product is controlled to enter the test mode and all LED indicators are lit in a cycle. The detector 5 quickly captures high-definition images at the preset trigger point and detects them, thus completing the entire workflow.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
