[0002] Visual recognition LED appearance inspection equipment is a device that uses computer vision technology to automatically inspect the appearance of LEDs. It acquires images of LED products through a high-resolution camera and a dedicated light source, and then uses image processing algorithms to identify and detect defects on the product surface, such as scratches, cracks, and color abnormalities. This equipment can complete inspection tasks quickly and accurately, improve production efficiency, and reduce the error rate of manual inspection.

[0003] The current method for inspecting the appearance of LEDs involves energizing the LED, taking a picture of one side of the LED, and then rotating the LED to take a picture of the other side. This method has certain drawbacks. When the LED is rotated after being energized, each side needs to be inspected one by one, which is slow and inefficient. In addition, if the rotation angle is not properly controlled, it is easy to miss some LEDs. Therefore, a visual recognition-based LED appearance inspection device is proposed to address the above problems. Utility Model Content

[0027] 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.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-8 This utility model provides a technical solution:

[0030] The LED appearance inspection device based on visual recognition includes an inspection device body 1. A bracket 2 is fixedly connected to the left side of the inspection device body 1. A drive assembly 3 is fixedly connected to one side of the bracket 2. A fixing assembly 5 is installed inside the drive assembly 3. The drive assembly 3 includes a housing 31. A limit groove 32 is formed inside the housing 31. An electric telescopic rod 33 is fixedly connected to the inner side of the housing 31 near the limit groove 32. A toothed plate 34 is fixedly connected to the end of the piston rod of the electric telescopic rod 33. An extension plate 35 is fixedly connected to the front end of the housing 31. A shaft rotation hole 36 is formed inside the extension plate 35. The fixing assembly 5 includes a flexible wire 51. A rotating column 52 is fixedly connected to the outer side of the flexible wire 51. A gear 53 is fixedly connected to the outer side of the rotating column 52. A clamping shell 54 is fixedly connected to the front end of the rotating column 52. The gear 53 meshes with the upper end of the toothed plate 34.

[0031] As a further implementation of this solution, the front and rear ends of the toothed plate 34 are fixedly connected to rails. The toothed plate 34 is slidably connected to the inner side of the limiting slide groove 32 through the rails. A gap is set between the right end of the toothed plate 34 and the right end of the limiting slide groove 32. Through the above settings, this structural design makes the toothed plate 34 more stable during sliding. The setting of the rails effectively restricts the direction of movement of the toothed plate 34, preventing it from deviating or shaking during movement. At the same time, the gap between the right end of the toothed plate 34 and the right end of the limiting slide groove 32 provides the necessary space for the installation and movement of other components.

[0032] As a further implementation of this solution, a horizontal plate 37 is fixedly connected to the front end of the housing 31, and a camera 38 is fixedly connected to the bottom end of the horizontal plate 37. The camera 38 is aligned vertically with the light-emitting diode body 4. The electric telescopic rod 33, the camera 38 and the detection equipment body 1 are electrically connected. Through the above settings, the camera 38 can accurately align with the light-emitting diode body 4, ensuring that the captured image is clear and accurate, providing a high-quality data foundation for subsequent image processing and defect detection.

[0033] As a further implementation of this solution, a ball bearing 58 is fixedly connected to the outside of the rotating column 52. The ball bearing 58 is fixedly connected to the inside of the shaft rotation hole 36. The rear end of the rotating column 52 extends out of the rear end of the shaft rotation hole 36. The gear 53 is installed inside the housing 31. A rotating hole is opened on the inner side of the housing 31 near the rotating column 52 and the gear 53. The flexible wire 51 is electrically connected to the detection equipment body 1. Through the above settings, this structural design makes the transmission more precise and efficient, and can accurately control the rotation angle of the light-emitting diode body 4 to ensure the integrity and accuracy of the detection. The flexible wire 51 has a certain length so as not to affect the rotation of the rotating column 52.

[0034] As a further implementation of this solution, the inner side of the clamping shell 54 is provided with a slot 55 and a flared mouth 57. A spring plate 56 is slidably connected to the inner side of the slot 55. The spring plate 56 is electrically connected to the flexible wire 51. The pins of the light-emitting diode body 4 are in contact with the spring plate 56. The pins of the light-emitting diode body 4 are inserted into the flared mouth 57 and the slot 55. Through the above settings, it is possible to accommodate pins of different sizes, improve the compatibility and adaptability of the device, and further improve the efficiency and reliability of detection.

[0035] As a further implementation of this solution, a dovetail-shaped slider is fixedly connected to one side of the spring plate 56, and a dovetail-shaped groove is opened on the inner side of the clamping shell 54 near the spring plate 56. The dovetail-shaped slider of the spring plate 56 is embedded in the dovetail-shaped groove of the clamping shell 54. The spring plate 56 is installed at both the upper and lower ends of the slot 55. Through the above settings, it is possible to effectively prevent the light-emitting diode body 4 from shifting or falling off, thereby ensuring the stable clamping and electrical connection of the pins of the light-emitting diode body 4, improving the stability and reliability of the device, and further improving the accuracy and efficiency of detection.

[0036] Workflow: When simultaneously testing multiple LED bodies 4, the LED bodies 4 are first installed at one end of the fixing component 5. The leads of the LED bodies 4 are inserted into the flared opening 57. The flared opening 57 is an expansion design to improve the convenience of inserting the LED bodies 4. After the leads of the LED bodies 4 enter the slot 55, the leads of the LED bodies 4 contact the two spring plates 56. The spring plates 56 deform, which clamps the leads of the LED bodies 4 and fixes them in place. The spring plates 56 slide inside the slot 55. At this time, the LED bodies 4 are electrically connected to the testing device body 1 through the spring plates 56 and the flexible wire 51. The LED bodies 4 are then powered on and emit light. After multiple LED bodies 4 are installed, the camera 38 is controlled by the testing device body 1 to take a picture of one side of the LED bodies 4. The appearance of the LED bodies 4 is then analyzed by the testing device body 1. At this time, the electric telescopic rod 33 controlled by the detection device body 1 drives the toothed plate 34 to move. The toothed plate 34 slides inside the limiting groove 32, which limits the movement direction of the toothed plate 34. When the toothed plate 34 moves, it simultaneously drives multiple externally meshing gears 53 to rotate. The gears 53 drive the rotating column 52 and the clamping shell 54 to rotate simultaneously. The rotating column 52 is rotatably connected to the shaft rotating hole 36 through the ball bearing 58. At the same time, the rotating column 52 will drive the flexible wire 51 to twist. The flexible wire 51 is a flexible wire and does not affect the normal rotation of the rotating column 52. When the clamping shell 54 rotates, it will drive the light-emitting diode body 4 to rotate, thereby taking pictures and detecting the other side of the light-emitting diode body 4, and then analyzing whether the light-emitting diode body 4 is qualified, thus completing the detection work. Through the above principle, when the device detects the appearance of the light-emitting diode body 4, it can accurately control the rotation angle of multiple light-emitting diode bodies 4, thereby ensuring the accuracy and completeness of the detection of the light-emitting diode body 4, and improving the efficiency of the detection of the light-emitting diode body 4.
