Both sides of the fixed seat 223 are connected with movable components 24, and the movable components 24 are used for the transmission of thin sheets. The fixed seat 223 is connected to the vertical plate 21. A rotating shaft 221 is connected between the two groups of movable components 24, and the rotating shaft 221 is slidably connected to one end of the fixed seat 223.

The first sensor 222 is disposed at the center of the moving base 22 for detecting whether there is a sheet on the moving base 22 .

[0036] By setting up a transmission mechanism, since the transmission modules 20 can be set up independently, the staff can select the number of transmission modules 20 according to actual production needs, and obtain a transmission mechanism of the required length through free combination, which is convenient for adjusting the transmission distance, and through the free combination of the transmission modules 20, it is convenient to increase and reduce the workstations to adapt to different types of thin film production.

The centering mechanism 50 is arranged on the transmission module 20 and is located on one side of the rotating mechanism 30, and the centering mechanism 50 is used for correcting the position of the thin film. The thin film is sent to the transmission module 20 corresponding to the rotating mechanism 30 and the centering mechanism 50 respectively through the transmission mechanism, and the thin film is first turned under the action of the rotating mechanism 30 and the suction cup assembly 40, and then the position of the turned thin film is adjusted by the centering mechanism 50, thereby realizing the direction correction and position adjustment of the thin film, thereby improving production efficiency.

[0038] Specifically, the rotating mechanism 30 includes a mounting frame 31, a rotating driving member 32 and a rotating member 33. The mounting frame 31 is arranged on the base 10.

A synchronous wheel 332 is provided on the rotating shaft 331. The synchronous wheel 332 is connected to the output end of the rotating driving member 32 through a second synchronous belt. In this embodiment, the rotating driving member 32 is a servo motor, and a rotating synchronous wheel 332 that transmits synchronously with the synchronous wheel 332 is connected to its output end. When the rotating driving member 32 is started, the rotating shaft 331 rotates synchronously with the rotating driving member 32, thereby driving the suction cup assembly 40 to turn, thereby realizing the direction of rotation of the sheet.

The suction cup 41 is provided with a plurality of groups of suction nozzles 42 arranged circumferentially for sucking the thin sheet. The suction cup 41 is connected to the rotating mechanism 30. When the thin sheet is sucked, the thin sheet is sucked by the suction nozzle 42, so that the thin sheet is closely attached to the suction nozzle 42, thereby realizing the suction of the thin sheet by the suction cup assembly 40.
