s3, the transport mechanism 3 transports the empty jig 42 to the upper part of the transfer mechanism 7, and the second jacking cylinder 721 jacks up the positioning plate 722 and clamps the empty jig 42 to continuously jack up to the lower part of the object placing plate 54 for positioning;

S4, the pushing assembly 52 is matched with the second driving cylinder 535 and the pushing cylinder 542 to perform blanking on the copper substrate in the tray 53 to the corresponding empty-load jig 42;

s5, the second lifting cylinder 721 descends the positioning assembly 72 bearing the full-load jig 42, and descends the full-load jig 42 to the conveying mechanism 3;

S6, the transporting mechanism 3 conveys the full-load jig 42 to the lower part of the jig collecting assembly 6 and is positioned above the first jacking cylinder 63, the first jacking cylinder 63 jacks up the full-load jig 42 into the jig collecting assembly 6, at the moment, the limiting assembly 62 fixes the clamping position of the full-load jig 42, and the first jacking cylinder 63 contracts and resets, so that the feeding operation of the copper substrate is completed.

Before step S1, the placement plate 54 carrying the trays 53 is pulled out from the lower portion of the pushing assembly 52 through the sliding rail, so as to facilitate batch placement of copper substrates into each of the slots 530.

After step S1 is completed and before step S2 is performed, after the placement plate 54 is pushed into place, the pushing motor 522 starts to drive the stroke pushing pins 523 and pushes the copper substrates in the material tanks 530 to move towards the movable plate 532, when the number of copper substrates in each material tank 530 is different, the corresponding stroke pushing pins 523 shrink to keep the first copper substrate row to abut against the movable plate 532, at this time, the first driving cylinder 527 drives the pressing module 524 to descend until the pressing block presses and fixes the copper substrates in the second copper substrate row.

In step S2, the output shaft of the jacking motor 44 is contracted by a defined distance, which is a distance of one thickness of the jig 42.
