The second support rods and the first support rods are staggered along the longitudinal direction. The multiple groups of second support rods are also used to carry pallets. When the feed rack 2 collects a certain number of pallets, the discharging cylinder 5 drives the shuttle car 7 to move to the bottom of the feed rack 2, and the lifting screw 4 drives the feed rack 2 to move downward. The multiple groups of first support rods move to the gap between the multiple groups of second support rods and continue to move downward. The pallets fall onto the shuttle car 7, and the discharging cylinder 5 drives the shuttle car 7 to move to the initial position. The pallets are manually moved away to complete loading and unloading.

The suction cup cylinder 23 extends and the suction cup 24 fixed on the suction cup cylinder 23 grabs the mobile phone display panels in the tray one by one and places them on the laser cutting equipment for processing;

[0038] (4) The discharge lifting platform mechanism 3 drives the feed rack 2 to move upward through the lifting screw 4, the positioning cylinder 17 fixed on the ferry plate 16 retracts, and the tray falls onto the feed rack 2 of the discharge lifting platform mechanism 3, and the ferry plate 16 returns to its initial position;

[0039] (5) After the feed rack 2 collects a certain number of empty pallets, the discharge cylinder 5 drives the shuttle trolley 7 to move to the bottom of the feed rack 2. The lifting screw 4 of the discharge lifting platform mechanism 3 drives the feed rack 2 to move downward. The shuttle trolley 7 of the discharge mechanism 8 receives the empty pallets and returns to the initial position. The pallets are manually moved away, and the loading action is completed.
