[0002] Mini LED is a new type of display technology with LED chips ranging from 50 to 200 micrometers in size. It uses direct-lit backlighting and achieves higher brightness, contrast, color gamut, and longer lifespan through local dimming technology. Mini LED technology not only enhances the visual experience but also solves the problem of uneven backlighting in traditional LEDs, resulting in a more uniform and detailed image. Furthermore, Mini LED technology is characterized by its thinness, lightness, and energy efficiency, and is widely used in high-end televisions, professional monitors, laptops, and other fields.

[0003] MiniLED, as a new generation of display technology, has advantages over traditional LEDs, such as high energy efficiency, long lifespan, and high resolution. Major consumer electronics manufacturers are experiencing a surge in demand for it. However, due to its small chip size and dense layout, quality inspection is difficult, and the detection accuracy and efficiency are insufficient, resulting in low yield and high costs. This has become an industry bottleneck for the large-scale mass production and application of MiniLED. Therefore, this utility model proposes a testing device for MiniLED production to solve the above problems. Utility Model Content

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a testing device for Mini LED production, including a base 1, a testing platform 2, and a support frame 3. The testing platform 2 is located on the top of the base 1, and the support frame 3 is fixedly connected to the back side of the base 1. A testing mechanism is located on the top of the support frame 3. A moving platform 4 is located inside the base 1, and an automatic feeding mechanism is located on the top of the moving platform 4. Multiple Mini LEDs are placed on the testing platform 2, and the automatic feeding mechanism moves the multiple Mini LEDs downward toward the testing mechanism. The testing mechanism automatically tests the multiple Mini LEDs. After the test is completed, the automatic feeding mechanism drives the Mini LEDs to reset, and the Mini LEDs are then removed.

[0020] Guide rods 9 are symmetrically fixedly connected to both sides of the base 1, and through holes 14 are symmetrically provided on both sides of the movable platform 4. The movable platform 4 is slidably connected to the guide rods 9 through the through holes 14.

[0021] A cylinder 10 is fixedly installed inside the moving stage 4. The output end of the cylinder 10 is fixedly connected to one side of the moving stage 4. The moving stage 4 and the high-precision camera 13 are parallel to each other. The output end of the cylinder 10 can drive the moving stage 4 to move forward. The gripper 6 is connected to the moving stage 4 as one unit through the sliding frame 5, so that the Mini LED card located in front of the gripper 6 can be inserted into its interior.

[0022] The automatic feeding mechanism includes a sliding frame 5, grippers 6, a lead screw 7, a motor 8, and a slider 15. The sliding frame 5 is located on the top of the moving platform 4. Multiple sets of grippers 6 are fixedly connected to the top of the sliding frame 5. The lead screw 7 is rotatably connected inside the moving platform 4. The motor 8 is fixedly installed on one side of the base 1. The slider 15 is fixedly connected to one side of the sliding frame 5. The outer wall of the slider 15 is slidably connected to the inner wall of the moving platform 4. One end of the lead screw 7 is fixedly connected to the output end of the motor 8, and the other end of the lead screw 7 passes through the interior of the slider 15 and is threadedly connected to it. The bottom of the grippers 6 is fitted and connected to the top of the detection platform 2. The spacing between a set of grippers 6 is equal to the length of the Mini LED. After the LED card is inserted into the interior of a set of grippers 6, the lead screw 7 and the slider 15 are threaded together, and the moving stage 4 restricts the movement trajectory of the slider 15. When the motor 8 drives the lead screw 7 to rotate in the forward direction inside the moving stage 4, it can drive the slider 15 to move to the left. The grippers 6 are connected to the slider 15 as one unit through the sliding frame 5. The slider 15 can drive the grippers 6 to move to the left on the top of the detection stage 2. The grippers 6 push the card into its interior and move the MiniLED to below the high-precision camera 13, completing the automatic feeding and improving the detection efficiency.

[0023] The detection mechanism includes a second cylinder 11, a connecting frame 12, and a high-precision camera 13. The second cylinder 11 is fixedly mounted on the top of the support frame 3. The output end of the second cylinder 11 is fixedly connected to the connecting frame 12, and the high-precision camera 13 is fixedly mounted on the bottom of the connecting frame 12. When the Mini LED moves below the high-precision camera 13, the output end of the second cylinder 11 drives the high-precision camera 13 downwards via the connecting frame 12, allowing the high-precision camera 13 to capture images of the Mini LED. The high-precision camera 13 has high resolution and a high frame rate, enabling it to capture minute features of the Mini LED wafer or module. During image capture, a stable light source ensures that the image of the Mini LED being detected is clear, without shadows or reflections. The image is then converted into an electrical signal and transmitted to an image processing system in a computer. The image processing system uses algorithms to extract and identify features in the image, which may include Mini LED characteristics. The system can determine whether the object being tested has defects or abnormalities by comparing the brightness, color, shape, and size of the LED with preset standards or templates. After the test is completed, the output end of the second cylinder 11 drives the high-precision camera 13 to move upward and reset through the connecting frame 12.

[0024] When the motor 8 drives the lead screw 7 to rotate in the opposite direction inside the moving stage 4, it can drive the slider 15 to move to the right. The gripper 6 is connected to the slider 15 through the sliding frame 5. The slider 15 can drive the gripper 6 to move to the right on the top of the detection stage 2, and move the Mini LED that has been detected out from under the high-precision camera 13. The output end of the first cylinder 10 drives the gripper 6 to move backward and reset through the moving stage 4.

[0025] The testing equipment for Mini LED production has a cylinder 10 whose output can drive the moving stage 4 to move forward. The gripper 6 is connected to the moving stage 4 via a sliding frame 5, allowing the Mini LED located in front of the gripper 6 to be inserted into it. The lead screw 7 is threadedly engaged with the slider 15, and the moving stage 4 restricts the movement trajectory of the slider 15. When the motor 8 drives the lead screw 7 to rotate forward inside the moving stage 4, it can drive the slider 15 to move to the left. The gripper 6 is connected to the slider 15 via the sliding frame 5, and the slider 15 can drive the gripper 6 to move to the left on the top of the testing stage 2. The gripper 6 pushes the Mini LED inserted into it to move below the high-precision camera 13, completing automatic feeding and improving testing efficiency.
