The loading position 1 and the transfer position 2 are on the same straight line in the horizontal direction, the transfer position 2 and the feeding position 3 are on the same straight line in the vertical direction, the loading position 1 means that the first carrier 210 is located at a position capable of receiving the manual film 10, the transfer position 2 means that the first carrier 210 is located at a position capable of transferring the film 10 to the second carrier 310, the transfer position 2 means that the second carrier 310 is located at a position capable of receiving the manual film 10 transferred by the first carrier 210, and the feeding position 3 means that the film 10 on the second carrier 310 can be sucked by the film coating manipulator.

The first carrier 210 may be a pallet, or a tray, and the first driving member 200 may be any linear motion unit capable of driving the first carrier 210 to move to and from the loading position 1 and the transferring position 2, such as an air cylinder, an electric screw rod, or a belt conveying mechanism; the second carrier 310 may be a pallet, a pallet or a tray, and the second driving member 300 may be any linear motion unit such as an air cylinder, an electric screw rod or a belt mechanism that can drive the second carrier 310 to move to and from the transfer station 2 and the feeding station 3; the processing chip of the control element may be, but is not limited to, a single chip microcomputer, an ARM (Advanced RISC Machine: high-end reduced instruction set Machine), and an FPGA (Field-Programmable Gate Array).

As shown in fig. 1 (looking at the left-hand part of the film supply device alone), the first carrier 210 is already filled with film 10 and the second carrier 310 is waiting for the last film 10 to be sucked away.

With reference to fig. 1 and 2, in the film supplying apparatus, a first carrier 210 is first manually loaded at a loading position 1 to load a wad of films 10, then a first driving member 200 drives the first carrier 210 to move to a transfer position 2 to transfer the films 10 to a second carrier 310 located at the transfer position 2, after the films 10 are transferred to the second carrier 310, the first carrier 210 is driven by the first driving member 200 to return to the loading position 1 to continue waiting for loading, a second driving member 300 drives the second carrier 310 to move to a feeding position 3 for feeding a film laminating manipulator, and after the films 10 on the second carrier 310 are completely supplied, the second carrier 310 is driven by the second driving member 300 to return to the transfer position 2 to wait for the transfer of new films 10 from the first carrier 210 to the second carrier 310.
