[0002] Automobile headlights have multiple functions such as lighting and warning lights. In addition to their functions, they also have strict requirements on the appearance after installation on the body. For example, the fit between the installed headlights and the body sheet metal needs to have a uniform gap to ensure the appearance. The part that the installed headlights and the body sheet metal touch is the lampshade, so it is particularly important to test the lampshade of the assembled headlights.

[0032] Among them, when it is necessary to change the type of headlight to be detected, the steps are as follows: the first step is to move the conveying seat 21 to the detection station 102, first the driving end of the lifting drive structure 30 is extended to drive the lampshade detection upper seat 50 to descend, and then the connection between the lampshade detection upper seat 50 and the lifting frame 31 is released, so that the lampshade detection upper seat 50 is erected above the headlight positioning lower seat 40 under the cooperation of the limiting column 42 and the limiting cone column 52; the second step is to release the connection between the conveying seat 21 and the headlight positioning lower seat 40 and start the lifting support unit 70. When the lifting support unit 70 switches from the retracted state to the extended state, the driving end of the lifting support unit 70 passes through the outlet, and the headlight positioning lower seat 40 and the lampshade detection upper seat 50 are supported above the conveying seat 21; the third step is to open the two doors 122 at the rear end of the machine frame 12, and move the transfer vehicle to the upper portion of the conveying seat 21. At the rear end of the main body 10, after the transfer vehicle is detachably locked with the main body 10, the lower seat 40 for positioning the lamp and the upper seat 50 for detecting the lamp shade are manually pushed onto the transfer vehicle, and after the lock between the transfer vehicle and the main body 10 is released, the transfer vehicle and the lower seat 40 for positioning the lamp and the upper seat 50 for detecting the lamp shade are transported to the storage position; in the fourth step, another transfer vehicle carrying the lower seat 40 for positioning the lamp and the upper seat 50 for detecting the lamp shade for replacement are moved to the rear end of the main body 10 and detachably locked with the main body 10, and the lower seat 40 for positioning the lamp and the upper seat 50 for detecting the lamp shade for replacement are manually pushed onto the lifting support unit 70, and after the lifting support unit 70 is switched from the extended state to the retracted state, the lower seat 40 for positioning the lamp for replacement is detachably connected with the conveying seat 21, and the upper seat 50 for detecting the lamp shade for replacement is detachably connected with the lifting frame 31. In this way, the lamp shade detection device for detecting the lamp changes the type of lamp to be detected.
