[0002] Currently, in practical applications of LED chips, LED chips are typically soldered onto circuit boards. When testing the operational status of LED chips, a common practice is to move the chip board under a testing device, photograph it with a camera, and use image recognition technology to determine if the chips are functioning correctly.

[0003] However, when a fault is detected in an LED bead, it is often necessary to check the solder joints between the LED bead pins and the circuit board in order to find out the cause of the fault. In the existing technology, the entire LED bead board needs to be manually flipped over to check the condition of the pin solder joints. The manual flipping operation increases the workload of the operator and reduces the detection efficiency. On the other hand, in the process of frequent manual operation, not only is it easy to make operation errors, resulting in damage to the LED bead board or LED bead, but the accuracy and stability of manual detection are also difficult to guarantee.

[0020] 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.

[0021] Please see Figure 1-3 This embodiment provides an LED bead testing device to increase the convenience of testing LED beads.

[0022] Specifically, it includes a detection device 1, a mounting bracket 2, a camera 3, a linear guide rail 4, and a mounting assembly 5; the mounting bracket 2 is mounted on the detection device 1, the camera 3 is mounted on the top of the mounting bracket 2, the linear guide rail 4 is mounted on the detection device 1, and the mounting assembly 5 is drivenly connected to the linear guide rail 4 so that the linear guide rail 4 moves the mounting assembly 5 below the camera 3 during operation.

[0023] In actual use, the LED light bead board is placed on the mounting component 5 and fixed by the mounting component 5. The linear guide 4 is then started. The linear guide 4 starts to operate according to the preset program or instructions, driving the mounting component 5 to move smoothly along a specific trajectory, and finally accurately moving the mounting component 5 to below the camera 3.

[0024] Once the installation component 5 reaches the designated position, the camera 3 begins to work. The camera 3 will take pictures of the LED light bead board located below it according to the set parameters, such as shooting frequency, exposure time, and shooting resolution. The image information captured by the camera 3 will be transmitted to the image processing system connected to it.

[0025] The image processing system uses specialized image recognition algorithms and analysis software to process and analyze the images captured by camera 3. By comparing the image characteristics of normal LED beads with the state of the beads in the current captured image, it determines whether the LED beads are faulty, such as whether the beads are lit, whether the brightness is normal, or whether the color is abnormal.

[0026] In detail, to facilitate the rotation of the LED bead board and the inspection of its pin soldering parts, the mounting assembly 5 in this example includes a mounting plate 501 that is driven and connected to the linear guide rail 4. Bearing seats 502 are provided on both the left and right sides of the upper surface of the mounting plate 501. Rotating shafts 503 are rotatably connected inside the two bearing seats 502. A horizontal plate 504 is provided at the opposite end of the two rotating shafts 503. Plastic clips 505 are installed on the front and rear sides of the upper surface of the horizontal plate 504 for clamping and fixing the LED bead board. A motor 506 that is driven and connected to the rotating shaft 503 is provided on one of the bearing seats 502.

[0027] If an LED bead malfunction is detected, mounting component 5 plays a further role. Motor 506 in mounting component 5 starts, and its control unit is connected to the control system of detection device 1, receiving control signals to drive shaft 503 to rotate. This, in turn, causes the horizontal plate 504, which holds the LED bead board, to rotate. After the horizontal plate 504 rotates 180°, the LED bead board's pins face upwards, and camera 3 captures an image again, obtaining image information of the LED bead pins and the solder joints on the circuit board. The image processing system analyzes the newly acquired image, checking for issues such as cold solder joints, detached solder joints, and short circuits, thereby comprehensively diagnosing the cause of the LED bead malfunction.

[0028] Furthermore, in order to facilitate the adjustment of the distance between the two bearing seats 502 and thus adapt to LED lamp bead boards of different sizes, a distance is maintained between the two bearing seats 502 in this embodiment. An adjustment component 6 is also provided inside the mounting plate 501 to adjust the distance between the two bearing seats 502.

[0029] In detail, the adjustment component 6 includes a mounting groove 601 that is horizontally opened inside the mounting plate 501. A screw 602 is rotatably connected between the left and right sides of the inner wall of the mounting groove 601. A connecting block 603 is threadedly connected to the outer side of the screw 602. The two connecting blocks 603 are respectively connected to the bottom of the two bearing seats 502.

[0030] Furthermore, a knob is provided on the side of the mounting plate 501 to be fixedly connected to the screw 602. The outer side of the screw 602 has two threaded grooves, and the thread directions of the two threaded grooves are opposite.

[0031] In actual use, rotating the knob fixedly connected to the screw 602 on the side of the mounting plate 501 causes the screw 602 to rotate. Since the screw 602 has two threaded grooves with opposite directions on its outer side, and these grooves are threaded to two connecting blocks 603 respectively, and the connecting blocks 603 are connected to the bottom of the two bearing seats 502 respectively, rotating the knob causes the screw 602 to rotate, driving the two connecting blocks 603 to move towards or away from each other within the mounting groove 601, thereby adjusting the distance between the two bearing seats 502. After adjusting the distance, the LED bead board is placed on the horizontal plate 504, and the LED bead board is firmly clamped and fixed using the plastic clips 505 on the front and rear sides of the upper surface of the horizontal plate 504.

[0032] In addition, in order to ensure the spacing between the two bearing seats 502, the upper surface of the mounting plate 501 in this embodiment is provided with two sliding grooves, and the bottom of the bearing seat 502 is provided with two sliders 604, which are slidably connected inside the two sliding grooves respectively.

[0033] In actual use, when the two bearing seats 502 move in opposite directions or back to back, the slider 604 at the bottom of the bearing seat 502 will slide synchronously in the groove on the upper surface of the mounting plate 501. The cooperation between the slider 604 and the groove provides a stable guiding effect for the movement of the bearing seat 502, restricting the bearing seat 502 to move in a straight line along the direction of the groove, ensuring that the spacing adjustment between the two bearing seats 502 can be accurately carried out in the preset direction, and avoiding deviation or shaking.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, 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 a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] 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.
