[0026] In a specific example, the multi-stage sliding pull-out mechanism 11 adopts a double-stage structure, and the tray support seat 12 includes a support vertical plate and a tray support plate, the two support vertical plates are arranged front and back, and the tray support plate is arranged horizontally on the support vertical plate. The tray limiter 13 corresponds to the limiter of the tray, and is arranged on the support vertical plate or the tray support plate.

[0027] Furthermore, a material tray sensor 14 is provided on the topmost layer of the multi-stage sliding and pulling mechanism 11 or at the material tray support seat 12 .

[0028] Among them, see Figure 3 A lifting limit block 21, an L-shaped tray rear end limit sheet metal 22 and a top tray sensor 23 are set on the top of the lifting drive module 20, a displacement sensor 24 is set on the lifting path of the lifting drive module 20, and a bottom hard stop 25 is set at the bottom of the lifting drive module 20.

[0029] Among them, see Figure 4 The tooth fork assembly 30 includes a tooth fork base plate 31 and two tooth fork ribs 32 extending forward. The two tooth fork ribs 32 are arranged at both ends of the tooth fork base plate 31 and extend forward. The rear end face of the tooth fork base plate 31 is installed to the lifting movable end of the lifting drive module 20.

[0030] Furthermore, a material sensing photoelectric switch 33 according to a preset number of material trays is also provided on the tooth fork rib plate 32, and is used for detecting that when the number of material trays reaches a preset number, the controller sends a start descending instruction to the lifting drive module 20.
