The illuminating lamp 43 emits light all the time, and the light passes through the paired second glass windows 42 and the water in the water storage tank 6, and then relies on the second brightness sensor 41 to detect its brightness. After the level is reached, the brightness sensed by the second brightness sensor 41 will be lower than the corresponding value, so the second brightness sensor 41 will generate signal feedback, so that the electric valve 46 will be opened, so that the drain pipe 45 will discharge the water in the water storage tank 6, and then the After time, the water in the water storage tank 6 has been drained substantially, and now the second water pump 37 starts, so that the external water source enters the spherical body 39 through the water inlet pipe 38, and then relies on the spray hole 40 on the spherical body 39 to spray out. 40 is evenly distributed on the spherical body 39, so it can be flushed in all directions, so that the inner wall of the water storage tank 6 is cleaned. When the turbidity of the water discharged from the drain pipe 45 is reduced to a usable level, the electric valve 46 is closed. The water ejected from the spray hole 40 is then stored in the water storage tank 6 to facilitate water storage.

A method for detecting the quality of a finished product of an automobile LED lamp, the specific steps are as follows:

The first step is to start the driving motor 22, and the driving motor 22 will drive the clamping plate 21 to rotate counterclockwise to the horizontal position through the rotating arm 23, put the car lamp to be tested into the lamp fitting groove 16, and the lamp will be in contact with the rubber convex ring 15, and the power connection position on the detection lamp just touches the corresponding connection post 13 to realize power-on, so that the detection lamp is turned on, and the rubber protruding ring 15 ensures that the space where the connection post 13 is located is close to the inside of the detection box 1 One side is sealed, and then the driving motor 22 is controlled to drive the clamping plate 21 to rotate, and the pair of second electric telescopic rods 17 are operated to extend during the rotation, and the lamp is fixed and clamped by the clamping block 18, and one of the second electric telescopic rods 17 is extended. The telescopic rod 17 drives the connected top block 20 to touch the start switch button on the laser lamp 19, and the laser lamp 19 emits laser light;

The second step, start the first water pump 3, the first water pump 3 pumps out the water in the water storage tank 6 through the water pump 4, then sprays the lamp body through the distributed nozzle 5, and starts the first electric telescopic rod 2 at the same time, the first The electric telescopic rod 2 is elongated, so that the push plate 48 moves laterally to the detection box 1. During the lateral movement, the rollers 49 pass through the inclined guide plates 50 at each position in turn. When passing by, the rollers 49 roll up along the inclined guide plates 50. Since the first electric telescopic rod 2 is connected to the detection box 1 through the telescopic connecting rod 24 and the first spring 25, the roller 49 drives the pushing plate 48 and the first electric telescopic rod 2 to rise together. When the roller 49 breaks away from the inclined guide plate 50, It falls down, that is, bumps up and down, so as to simulate the impact of the bumps in the driving process of the vehicle on the headlights of the car, and the water sprayed by the nozzle 5 simulates rainwater. The water spraying test is carried out on the bumpy headlights to detect whether the lamps are bumpy. Under the circumstances, whether the part connection position will be separated, causing water to enter;

Step 3: The energized lamp illuminates the first glass window 26 during the moving process, and the first brightness sensor 27 detects the brightness. When a certain part of the lamp is separated due to bumps during the detection process, water enters the lamp, causing the lamp to fail to work normally. When the light is turned on, if the brightness detected by the first brightness sensor 27 is lower than the set value, feedback will be generated, which means that there is a problem in the detection process of the car headlight;

Step 4: After the clamped car headlights have passed the rain and bump test, firstly control the first electric telescopic rod 2 to shrink and reset, and then control the driving motor 22 to drive the clamping plate 21 to rotate counterclockwise to the horizontal position, that is, from the detection box 1 Rotate out, because the second electric telescopic rod 17 still maintains an extended state at this time, relying on the clamping block 18 to clamp the lamp, so the laser lamp 19 still keeps lighting, so when the clamping plate 21 is rotated out and turned to the horizontal position At this time, the laser lamp 19 that lights up is just aligned with the sleeve 29, and the light that occurs is injected into the sleeve 29, and the brightness sensor switch 30 in the sleeve 29 just generates induction, so that the third electric telescopic rod 28 and the hot air blower 36 Start, the third electric telescopic rod 28 stretches, so that the lifting plate 31 descends, and the lifting plate 31 just descends to the clamping plate 21 in the horizontal position, and the groove 44 on the lifting plate 31 is then placed on the clamping plate 21. The lamp shells are butted together, and the water-absorbing cotton pad 32 inside the groove 44 is convenient for absorbing the water stains on the surface of the lamp shell.
