[0024] The inner wall of the bottom of the collecting tank 71 is inclined, and the lowest point of the bottom of the collecting tank 71 faces the curved pipe 62 .

[0025] Furthermore, by setting the bottom inner wall of the collecting tank 71 to be inclined, the cleaning agent dripping on the bottom inner wall of the collecting tank 71 can automatically flow into the curved pipe 62 under the action of gravity.

[0026] In this embodiment, when in 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 fit tightly on the second sealing ring 45. During testing, the deflection plate 52 is driven by the rotating table 51 to drive the multi-station assembly 7 to rotate. When the collecting groove 71 abuts against the stopper 42, the rotating table 51 stops rotating. At this time, the top of the collecting groove 71 will fit tightly with the first sealing ring 41. Then, the water pump 64 is started, and 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 headlight to clean the headlight. The cleaning agent after cleaning falls directly to 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.

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; 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; 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; 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.
