[0021] Please see Figure 1 , Figure 2 and Figure 3The outer wall of the support frame 1 is equipped with a self-cleaning mechanism for convenient periodic cleaning of the conveyor belt 2. The self-cleaning mechanism includes an L-shaped frame 5, which is mounted on the outer wall of the support frame 1. An electric telescopic rod 6 is mounted on the top of the L-shaped frame 5. A first magnet plate 7 is mounted on the output end of the electric telescopic rod 6. A cleaning brush 9 is mounted on the outer wall of the first magnet plate 7, and a second magnet plate 8 is mounted on the top of the cleaning brush 9. An angle motor 10 is mounted on the outer wall of the L-shaped frame 5. A first mounting plate 11 is mounted on the output end of the angle motor 10. The outer wall of the first mounting plate 11 has a mounting screw groove 12, and the inner wall of the first mounting plate 11 has a pipe groove 13. A second mounting plate 14 is mounted on the outer wall of the first mounting plate 11, and an air jet 15 is mounted on the outer wall of the second mounting plate 14. This mechanism periodically cleans the surface of the conveyor belt 2, keeping the belt surface clean and preventing dust and debris from affecting the detection accuracy and transportation of the neon lamp. In addition to stability, the automatic cleaning device can reduce the workload of manual cleaning and improve production efficiency. First, the second magnet plate 8 and the first magnet plate 7 are attracted to each other, and the cleaning brush 9 is installed below the output end of the electric telescopic rod 6. Then, the first mounting plate 11 and the second mounting plate 14 are attached and connected by bolts and mounting screw grooves 12. The jet generator 15 is then installed outside the first mounting plate 11. At this time, the conveyor belt 2 is in an empty state and in a working state. Then, the electric telescopic rod 6 works and drives the cleaning brush 9 to move downward. The cleaning brush 9 contacts the surface of the conveyor belt 2. The working conveyor belt 2 cleans the surface. Then, the angle motor 10 works and drives the jet generator 15 to rotate, so that the nozzle of the jet generator 15 is aimed at the surface of the conveyor belt 2. At this time, the jet generator 15 works and blows away the dust and debris on the belt with high-pressure airflow, thereby improving the detection accuracy and transportation stability of the neon lamp.

[0022] Please see Figure 1 and Figure 4The outer wall of the bracket 1 is equipped with a collection mechanism for conveniently collecting unsuitable products. The collection mechanism includes a first collection box 16, which is installed on the outer wall of the bracket 1. An extension platform 17 is installed at the bottom of the first collection box 16, and a second collection box 18 is installed at the top of the extension platform 17. Both the outer walls of the first collection box 16 and the second collection box 18 are equipped with paper identification frames 19 and magnetic adsorption plates 20. Currently, after inspecting the neon lamp, the existing system cannot classify and collect unsuitable products, so this needs to be improved. Firstly, the second... The collection box 18 is placed on the extension platform 17 and adheres to the magnetic plate 20 on one side of the first collection box 16, which improves the stability of the second collection box 18. Then, the external card is taken out. The contents of the card are external surface abnormality and electrical abnormality. The card is placed in the card identification frame 19 outside the first collection box 16 and the second collection box 18 respectively. At this time, the staff can classify and place different types of neon lamps (unqualified) into the first collection box 16 and the second collection box 18 respectively. The length of the extension platform 17 is not fixed and is designed according to the amount of detection to avoid one box being unable to fully contain the unqualified products.

[0023] The working principle is as follows: a neon lamp is placed on conveyor belt 2, which transports the neon lamp to the interior of screening box 3. Inside screening box 3, optical components such as cameras and sensors are used to inspect the appearance of the neon lamp, such as whether the lamp tube has cracks, damage, or stains, and whether the shape and position of the electrodes are correct. By connecting to the electrodes of the neon lamp, its electrical performance is tested, such as whether parameters such as starting voltage, working current, and luminous intensity meet the specified range. The control panel 4 uses a programmable logic controller (PLC) to control and coordinate the operation of the entire equipment. Operators can set detection parameters, monitor equipment operation status, and view detection results through the human-machine interface. The control system judges the detection data according to the preset qualification standards. If all indicators of the neon lamp meet the requirements, it is judged as a qualified product; otherwise, it is judged as an unqualified product. The surface of the conveyor belt 2 is cleaned regularly to keep the belt surface clean and avoid dust and debris affecting the detection accuracy and transportation stability of the neon lamp. At the same time, the automatic cleaning device can reduce the workload of manual cleaning and improve production efficiency. First, the second magnet plate 8 and the first magnet plate 7 are attracted to install the cleaning brush 9 below the output end of the electric telescopic rod 6. Then, the first mounting plate 11 and the second mounting plate 14 are attached and connected by bolts and mounting screw grooves 12. The jet 15 is installed on the outside of the first mounting plate 11. At this time, the conveyor belt 2 is in an empty state and in a working state. When the electric telescopic rod 6 works, it drives the cleaning brush 9 to move downward, and the cleaning brush 9 contacts the surface of the conveyor belt 2. The working of the conveyor belt 2 cleans the surface. After cleaning, the angle motor 10 drives the jet 15 to rotate, so that the nozzle of the jet 15 is aimed at the surface of the conveyor belt 2. At this time, the jet 15 blows away the dust and debris on the belt with high-pressure airflow, thereby improving the detection accuracy and transportation stability of the neon lamps. The existing method cannot classify and store unsuitable products after the neon lamps are detected, so this needs to be improved. First, the second collection box 18 is placed on the extension platform 17 and attached to the magnetic adsorption plate 20 on one side of the first collection box 16 to improve the placement stability of the second collection box 18. Then, the external card is taken out. The card contains the contents of external surface abnormality and electrical abnormality. It is placed in the card identification frame 19 on the outside of the first collection box 16 and the second collection box 18 respectively. At this time, the staff can classify and place different types of neon lamps (unqualified) into the first collection box 16 and the second collection box 18 respectively. The length of the extension platform 17 is not fixed and is designed according to the amount of detection to avoid the situation where one box cannot fully store unqualified products.
