[0029] The working principle of the above embodiment is:

[0030] (1) By simultaneously starting the first electric push rods 208 on the left and right sides, the connecting frames 207 on the left and right sides are driven to move up and down on the outside of the U-shaped slides 206 on the left and right sides, and then the mounting frame 1 and the driving mechanism 3 can be driven to adjust the height up and down, so that the tray and the materials in the tray can be transported to the processing tables at different heights for processing. The base 203 and the four universal wheels 204 cooperate with each other to move the feeder on the ground, thereby improving the convenience of transporting the feeder.

[0031] (2) By starting the moving module 301, the moving module 301 drives the connecting plate 303 to move forward, backward, left and right, and moves to the top of the pallet. Then, the second electric push rod 302 is started and drives the four suction cups 305 to move downward. The four suction cups 305 contact the pallet. At this time, the vacuum pump 306 is started and the air inside the four suction cups 305 is extracted. The four suction cups 305 suck the pallet. At this time, the pallet with suction is moved to the processing table under the drive of the moving module 301 and the second electric push rod 302. The vacuum pump 306 is then used to deflate the four suction cups 305. The four suction cups 305 fall off the pallet. Then, the material on the pallet can be processed and a cyclic feeding operation can be performed. This can reduce the labor of feeding and improve work efficiency.
