In the present application, after the loading assembly places the trays 40 one by one on the support table 25, it moves to a preset position under the drive of the transmission drive 21, and then performs shooting detection through the detection mechanism 30.

[0029] In the present application, the transmission drive member 21 is an electric slide.

[0030] Further, the loading assembly includes a loading bracket 22, a left lifting device 23 and a right lifting device 24, a plurality of trays 40 are stacked in the vertical direction along the loading bracket 22, and can move in the vertical direction along the loading bracket 22; the left lifting device 23 and the right lifting device 24 are respectively arranged on both sides of the loading bracket 22 and can drive the trays 40 to move in the vertical direction along the loading bracket 22, so as to place a single tray 40 on the support platform 25. In the present application, the stacked trays 40 move onto the support platform 25 under the action of gravity, the left lifting device 23 and the right lifting device 24 cooperate to move the second tray 40 from the bottom to the top upward, at this time only the last tray 40 is placed on the support platform 25, and the single tray 40 is moved to a preset position by the transmission drive 21.

[0031] Furthermore, the loading bracket 22 includes four stoppers 221, and the four stoppers 221 correspond to the four corners of the tray 40 respectively; the stoppers 221 are provided with stop angles 222, and the stoppers 221 position the tray 40 through the stop angles 222; the stoppers 221 are provided with notches 223, and the support platform 25 can drive the tray 40 to detach from the loading bracket 22 through the notches 223. In the present application, four stoppers 221 are provided, and the tray 40 can be limited at the four corners of the tray 40, so that the tray 40 can only move in the vertical direction along the loading bracket 22. When there is only one tray 40 on the support platform 25, the tray 40 can detach from the loading bracket 22 through the notch 223.

[0032] Further, the left lifting device 23 and the right lifting device 24 are symmetrically arranged, and the left lifting device 23 and the right lifting device 24 have the same structure.
