The feeding driving mechanism 303 comprises a feeding driving piece 311, a feeding connecting rod 312 and a feeding linkage rod 313, wherein the feeding driving piece 311 and the feeding linkage rod 313 are located below the first carrying platform 201, the upper end of the feeding connecting rod 312 is connected with a feeding rotating block 325, the lower end of the feeding connecting rod 312 passes through a feeding support through hole 208 and then is connected with the feeding linkage rod 313, the feeding driving piece 311 is fixed on the lower surface of the first carrying platform 201, and the driving rod of the feeding driving piece 311 is fixedly connected with the feeding linkage rod 313. The feeding driving member 311 drives the feeding linkage rod 313 to move up and down, so as to drive the first rotating shaft 308 to rotate, and the feeding rotating block 325 abuts against the feeding stop block 319. Specifically, the feeding connecting rod 312 lifts up to drive the feeding rotating block 325 to rotate clockwise until the feeding rotating block abuts against the first feeding stop portion 320 of the feeding stop block 319, so that the feeding loading member 301 is in a horizontal position matched with the first die fixing member 401; the feeding link 312 moves down, driving the feeding rotating block 325 to rotate counterclockwise until it abuts against the second feeding stopper 321 of the feeding stopper 319, so that the feeding loader 301 is in an upright position to be engaged with an external robot. Wherein, the included angle between the horizontal position and the vertical position of the loading piece 301 is 90 degrees. The design uses the feeding linkage rod 313 to drive each feeding connecting rod 312 to rotate, ensures the synchronization of overturning actions, and has compact structure and saves driving equipment. And the loading rotating block 325 cooperates with the loading stop block 319 to enable the loading member 301 to stay at a designated position after being turned over.

If the initial position before the rotation of the partial loading member 301 is not the vertical position or the horizontal position, when the loading driving member 311 drives the loading member 301 to rotate through the loading link 312, there is a case where the loading rotating block 325 of the partial loading member 301 has been abutted against the loading stop 319 and the loading rotating block 325 of the partial loading member 301 has not been abutted against the loading stop 319 (i.e., has not reached the designated position). To solve this problem, in this embodiment, the lower end of each feeding link 312 is connected to the feeding link 313 through a first elastic sheet, the first elastic sheet enables the feeding link 312 to be flexibly connected to the feeding link 313, and the first elastic sheet can absorb the excessive momentum to drive the feeding loading member 301 to abut against the feeding stop 319, so that the stop position of each feeding loading member 301 connected to the feeding link 313 is consistent after rotation. Specifically, when the feeding rotating block 325 of the part of the feeding loading member 301 is already abutted against the feeding stop block 319 (i.e. turned in place), and the feeding rotating block 325 of the part of the feeding loading member 301 is not abutted against the feeding stop block 319 (turned in place), the feeding driving member 311 continues to drive the feeding linkage rod 313 to act, so that the non-turned feeding loading member 301 continues to rotate until turned in place, and the turned-in-place feeding loading member 301 drives the first elastic sheet to deform through the feeding connecting rod 312 to absorb the surplus momentum, so that all the feeding loading members 301 are ensured to be turned and remain at the designated positions. The arrangement of the first elastic sheet can also make up the height difference between the feeding connecting rods 312 caused by installation or technology, and reduce the installation and processing requirements of the feeding connecting rods 312.
