In order to make the image of the glass plate captured by the camera or the like clear, the light source plate is required to provide a camera light source. However, in the process of laser film removal, the position of the local film removal may coincide with the light source plate, and the problem that the light source plate is damaged by the laser direct light source plate may occur.

The focal length adjusting motor 42 rotates to drive the focal length adjusting screw 43 to rotate, and further drives the bearing plate 44 to move. When the carrier plate 44 moves, the focus adjustment slider slides along the focus adjustment guide rail 41 in cooperation with the carrier plate 44 to perform a guiding function. And the bearing plate 44 drives the second support frame 5 and the pickup mechanism 4 to slide when moving, so that the second support frame 5 and the pickup mechanism 4 are forced to slide close to or far away from the galvanometer component 7 on the first support frame 3, and the laser beam emitted by the galvanometer component 7 can always fall on the central vertex of the cambered surface glass 67 absorbed by the pickup mechanism 4. And because the second support frame 5 and the pickup mechanism 4 slide together, the problem that the pickup mechanism 4 interferes with the second support frame 5 in the sliding process is also avoided.

In this embodiment, as shown in fig. 7, a distance measuring instrument 68 is further disposed on the second supporting frame 5, and the distance measuring instrument 68 is fixed on the cross beam 10. The distance meter 68 is used to measure the distance from the distance meter 68 itself to the curved glass 67. Since the distance between the second support frame 5 and the first support frame 3 is known in the initial state, that is, the distance between the distance meter 68 and the galvanometer component 7 is known, the distance between the distance meter 68 and the galvanometer component 7 is obtained by subtracting the distance between the distance meter 68 and the cambered glass 67 from the distance between the distance meter 68 and the galvanometer component 7. The distance between the focal position of the laser beam emitted by the galvanometer component 7 and the galvanometer component 7 is known, and the distance between the focal position of the laser beam emitted by the galvanometer component 7 and the galvanometer component 7 minus the distance between the galvanometer component 7 and the cambered glass 67 obtains the distance that the pickup mechanism 44 needs to move. Meanwhile, a galvanometer adjusting guide rail is arranged on the first support frame 3 and arranged along the conveying direction of the conveying belt 2. The galvanometer adjusting slide block is slidably arranged on the galvanometer adjusting guide rail, the moving seat 46 is arranged on the galvanometer adjusting slide block, and the galvanometer component 7 and the camera 8 are both arranged on the moving seat 46. And a galvanometer adjusting motor is also arranged on the galvanometer adjusting guide rail and used for driving the galvanometer adjusting slide block to slide on the galvanometer adjusting guide rail. In the film removing process, as the film removing surface of the arc-surface glass 67 is in a certain arc shape, in order to enable the laser beam to always fall on the film removing surface in the film removing process, the vibrating mirror adjusting motor drives the vibrating mirror adjusting slide block to slide according to a derivative equation of the longitudinal displacement distance of the vibrating mirror relative to the initial position of the vibrating mirror, so that the vibrating mirror longitudinally displaces, and finally the focus of the laser beam always falls on the film removing surface in the film removing process; this is a matter that can be derived by a person skilled in the art based on the common general knowledge in the art and is not the point of the invention of this patent, and therefore is not described here.
