The clamping device 43 is provided with a pneumatic cylinder 47, which controls the drop of the vehicle lamp. Through the control of the control system on each motor and pneumatic cylinder, the vehicle lamp of different sizes and shapes can be realized, and the drop test in multiple directions can be realized, so as to meet the future drop test requirements of the vehicle lamp.

[0052] During the test, before the test, the clamping plate 48 is first lifted by the pneumatic cylinder 47, and then the clamping plate driving lead screw 42 is driven to rotate by rotating the hand wheel 41, and the movement direction of the clamping device 43 is ensured through the clamping guide rod 44, so as to realize the stable movement of the clamping device 43 and make the clamping device 43 close.

During the test, the retractable block 37 is retracted according to the instruction of the control system 5, and the turnover platform 31 will rotate downward at the moment of retraction, so as to realize the drop test of the through-type tail lamp. During the test, after the auxiliary arm 3 is lifted to the drop height required by the vehicle lamp test standard, the control system 5 controls the pneumatic cylinder 47 to retract the clamping plate 48, so as to realize the drop of the vehicle lamp at the preset posture and height. If it is necessary to ensure the angle during the drop, an angle measuring instrument can be used to continuously adjust the angle of the vehicle lamp.
