The pressing plate 300 is disposed parallel to the supporting plate 200, the pressing plate 300 and the supporting plate 200 define a flattening gap 11 in the up-down direction, and the film 20 is suitable to be placed in the flattening gap 11. That is, the lower surface of the pressure plate 300 is opposite to at least a portion of the upper surface of the pallet 200, the lower surface of the pressure plate 300 and the upper surface of the pallet 200 define a flattening gap 11, and the film 20 passes through the flattening gap 11. The pressing plate 300 and the supporting plate 200 can be stainless steel plates, the thickness of the pressing plate 300 can be 3mm-5mm, and the thickness of the supporting plate 200 can be 3mm-5mm, so that the method can adapt to different production process environments.

The pressing plate 300 has a starting end 310 and an ending end 320 in a longitudinal direction, and a transverse width of the starting end 310 of the pressing plate 300 is smaller than a transverse width of the ending end 320 of the pressing plate 300. The platen 300 has a flattened end 330 and a press-fit end 340 in a transverse direction, and a portion of a contour line of the flattened end 330 between the starting end 310 and the ending end 320 is configured as a flattened oblique line 331 in a projection plane parallel to the platen 300.

For example, the pressing plate 300 is parallel to a horizontal plane, and the longitudinal direction means a front-rear direction and the lateral direction means a left-right direction. The front end of the pressing plate 300 is a starting end 310, the rear end of the pressing plate 300 is an ending end 320, and the width of the starting end 310 of the pressing plate 300 in the left-right direction is smaller than the width of the ending end 320 of the pressing plate 300 in the left-right direction. The left end of the pressing plate 300 is a flattening end 330, the right end of the pressing plate 300 is a pressing end 340, and the contour line of the middle portion of the flattening end 330 in the front-rear direction is configured as a flattening oblique line 331, and the flattening oblique line 331 extends obliquely from front to rear and to the left.
