[0035] The first driving wheel 163 is driven to rotate by the servo motor 161, and the first driving wheel 163 drives the first driven wheel 164 through the first transmission belt 168 after rotating, thereby driving the first connecting shaft 162 to rotate, and the first connecting shaft 162 drives the first bevel gear 18 connected to the axial end portion to rotate, and the first bevel gear 18 on the first connecting shaft 162 drives the first bevel gear 18 connected to the lifting assembly 17 to rotate, thereby driving the lifting assembly 17.

[0039] The first bevel gear 18 connected to the lead screw 172 rotates after receiving the power of the transmission assembly 16, the lead screw nut 173 moves up and down on the lead screw 172, thereby adjusting the height of the belt conveyor 15, so that the cutting piece on the belt conveyor 15 can be raised to the height that the suction cup 14 can be adsorbed.
[0040] Specifically, as shown in Figure 7As shown, the rack 11 on both sides of the second fitting seat 171 is provided with a third fitting seat 174, the middle part of the third fitting seat 174 is fixedly connected with a connecting column 175 located in the cavity 111, the part of the connecting column 175 located in the cavity 111 is matched with a sliding block 176, the wall surface of the rack 11 located outside the connecting column 175 and close to the side of the belt conveyor 15 is provided with a second sliding groove 113, and the sliding block 176 is connected with the end of the belt conveyor 15 through the second sliding groove 113.

When the distance between the two ends of the cutting piece reaches a specified value, the belt conveyor 15 stops working. If the distance between the two ends of the cutting piece sensed by the first proximity sensors 102 on both sides of the belt conveyor 15 is not consistent, it means that the position of the stacked cutting piece is offset, and the operator can adjust the position of the stacked cutting piece according to the sensing results of the first proximity sensors 102 on both sides of the belt conveyor 15. The second proximity sensor 104 senses the distance between the belt conveyor 15 and the cutting piece to prevent the belt conveyor 15 from over-traveling during lifting and to monitor whether the position of the cutting piece on the belt conveyor 15 is offset during lifting. The operator can know this situation according to the sensing results of the second proximity sensor 104, so as to make quick adjustments.
