[0056] like Figure 2 As shown, in order to detect the performance and quality of the vehicle lamps, a testing device is set up. The testing device is located on the outer surface of the base plate 1, and detects the vehicle lamps that need to be detected. The testing device includes a light receiving box 8 with a detection component, and the detection component in the light receiving box 8 detects the vehicle lamps.

[0057] Specifically, in order to carry out the detection work, the outer surface of the light receiving box 8 is fixedly mounted on the outer surface of the bottom plate 1. When the car light is powered on, the light beam is irradiated into the detection port of the light receiving box 8, and the light beam is detected by the detection component. A lifting hydraulic cylinder 81 is fixedly mounted on the upper surface of the bottom plate 1, and a fixed frame 82 is fixedly mounted on one end of the piston rod of the lifting hydraulic cylinder 81.

[0058] Working principle: After placing the headlight to be inspected on the support pad 62 on the fixed support rod 61, the headlight is supported, and the deflection motor 71 on the fixed support rod 61 is started to drive the fixed housing 7 to deflect, and the fixed rod 72 on the fixed housing 7 is pressed on the upper surface of the headlight.

[0059] The driving motor 2 on the bottom plate 1 is started, and the driving motor 2 drives the cam connected thereto to rotate, and the driving rotation pulls the connecting rod 31 to move, and the connecting rod 31 drives the pushing sleeve 32 to move up and down in the supporting sleeve 33 under the supporting plate 21, and the supporting plate 21 is pushed up and down by pushing the supporting sleeve 33, and the tension spring 35 on the supporting push rod 34 is stretched along with the lifting, and the supporting spring 37 in the fixed sleeve 36 is stretched and reset, driving the supporting plate 21 to vibrate, and driving the headlight to vibrate synchronously, simulating the vibration of the headlight of the vehicle during the forming process;

[0060] The fixed frame 82 is lowered under the pull of the lifting hydraulic cylinder 81, so that the detection camera 83 in the fixed frame 82 takes a picture of the headlight and checks whether the headlight surface is cracked after vibration. The rotating motor 41 drives the headlight to deflect left and right, which is convenient for all-round detection. The fill light 84 fills in the light.

[0061] When performing light energy detection, the rotating motor 41 on the rotating seat 4 drives the mounting frame 42 to rotate, so that the light of the headlight faces the direction of the light receiving box 8. After the hydraulic cylinder 52 is adjusted to push the position of the telescopic hydraulic cylinder 51, the connector 53 can be driven to be consistent with the position of the connection port on the headlight. The telescopic hydraulic cylinder 51 pushes the connector 53 to be plugged into the connection port of the headlight for electrical connection, so that the headlight is powered on. The light is detected by adjusting the input current, and the light is irradiated on the detection port of the light receiving box 8. The light is detected by the detection component in the detection port. After the detection is completed, the rotating motor 41 drives the headlight to reset.

[0062] After the adsorption electromagnet 77 is powered off, the movable fixing block 75 releases the fixing of the fixing rod 72 under the force of the pulling spring 76. After the deflection motor 71 drives the fixed housing 7 to reset, the reset spring 73 can drive the fixing rod 72 to reset.
