[0035] The inner wall of the bottom of the collection tank 71 is inclined, and the lowest point of the bottom of the collection tank 71 faces the elbow 62.

[0036] Furthermore, by setting the inner wall of the bottom of the collection tank 71 to be inclined, the cleaning agent dripping on the inner wall of the bottom of the collection tank 71 can automatically flow into the elbow 62 under the action of gravity.

[0037] In this embodiment: during use, the vehicle lamp is placed on the second sealing ring 45. Under the action of the gravity of the vehicle lamp, the vehicle lamp will be closely attached to the second sealing ring 45. During detection, the rotary table 51 drives the deflection plate 52 to drive the multi-station assembly 7 to rotate. After the collection tank 71 abuts against the stop block 42, the rotary table 51 stops rotating. At this time, the top of the collection tank 71 will be closely attached to the first sealing ring 41;

[0038] Then the water pump 64 is started. The water pump 64 sucks the cleaning agent in the liquid storage tank 61 and sprays it from the nozzle 69 through the hose 65. The cleaning agent sprayed from the nozzle 69 acts on the vehicle lamp to clean the vehicle lamp. The cleaning agent after cleaning directly falls on the bottom of the collection tank 71 under the action of gravity and flows back into the liquid storage tank 61 through the elbow 62. After being filtered by the filter plate 63, the clean cleaning agent will be pumped back into the hose 65 by the water pump 64. Through the filtration of the filter plate 63, the cleaning agent can be reused multiple times;

[0039] By starting the two second motors 710 to drive the corresponding screw rods 72 to rotate, the two screw rods 72 then drive the two swing arms 74 to move through the two sleeves 73, and the two swing arms 74 then drive the spray head 69 to move through the frame 78. In addition, by controlling the extension and retraction of the electric push rod 798, the electric push rod 798 drives the rectangular seat 792 to move, and the rectangular seat 792 then drives the connecting plate 1 791 to move through the connecting plate 2 795 and the articulated arm 796, and the connecting plate 1 791 then drives the spray head 69 to rotate with the two rotating shafts 691 as the center of the circle, so that by adjusting the position and angle of the spray head 69, all-round cleaning of the headlights can be achieved;

[0040] By starting the two motors 76 to drive the two gear columns 77 to rotate in opposite directions, the two gear columns 77 then drive the two gears 75 to rotate, and the two gears 75 then drive the two swing arms 74 to rotate, and the two swing arms 74 rotate to move the lifting frame 78 up and down, so that the distance between the nozzle 69 and the headlight can be adjusted, so as to ensure that the distance between the nozzle 69 and the headlight is always consistent when the nozzle 69 cleans the headlight in all directions;

[0041] After the washing of the headlights is completed, the hot air blower 66 is started, and the hot air blower 66 sprays hot air from the nozzle 69 through the hose 65, and the sprayed hot air dries the headlights after washing with the cleaning agent, and the hot air generated during drying is discharged through the multiple exhaust pipes 43;

[0042] When the cleaning of the headlight is completed, the rotating table 51 is started to drive the multi-station assembly 7 to rotate and reset. Without the obstruction of the multi-station assembly 7, the light emitted by the headlight can be visually inspected through the camera 12. In addition, the robot arm 8 drives the camera 2 9 to take pictures of the fastener installation locations on the headlight to detect whether there are any missing fasteners on the headlight.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
