The technical solution proposed by the invention is as follows: providing a plate film pasting structure, which comprises a plate and a diaphragm, wherein the plate is provided with at least one unit surface and at least one step part positioned on the side edge of the unit surface on the film pasting side of a plate body, the step part has a height difference relative to the laterally adjacent unit surface, a dead angle space is arranged between the unit surface and the side end surface of the step part adjacent to the unit surface, the diaphragm is pasted on the film pasting side of the plate, and the diaphragm is pasted on the outer surfaces of the unit surface and the step part;
the plate is provided with at least one air accommodating hole, the air accommodating hole is formed in the step part, and the air accommodating hole extends from the step part back to the outer surface of the plate body towards the plate body and is communicated with the dead angle space.
In the above sheet material film structure, the step portion is formed around the outer periphery of the cell surface, and the step portion is provided with a plurality of the air accommodating holes distributed around the cell surface.
In the plate material film formation structure, the unit surface has a polygonal shape, and the plurality of air accommodating holes are distributed at each corner of the polygonal unit surface.
In the above sheet material film formation structure, the unit surface is a polygon, and the plurality of air accommodating holes are distributed at each side position of the polygon unit surface.
In the above-described sheet material film structure, the depth of the air accommodating hole in the thickness direction of the step portion is smaller than or equal to the thickness of the step portion.
In the above-described sheet material film-sticking structure, the sheet material body has a plurality of the cell surfaces arranged at intervals, and the step portion is formed around the outer peripheries of the plurality of the cell surfaces.
The invention has the advantages that the plate film pasting structure utilizes the step part of the plate higher than the unit surface to be provided with at least one air containing hole, and the air containing hole extends from the outer surface of the step part to be communicated to the dead angle space between the side end surface of the step part and the unit surface. In the roller film pressing operation, when the roller rolls the diaphragm from the step geometric area between the plate body and the step part to the outer surface of the step part, the gas in the dead angle space of the step geometric area can be discharged to the gas containing holes at the adjacent positions by the extrusion action of the roller, wherein before the diaphragm completely seals the gas containing holes, the gas containing holes are used for providing a gas escape path, so that part of the gas in the dead angle space can be discharged from the outer surface of the step part through the gas containing holes, until the diaphragm completely seals the opening of the gas containing holes at the outer surface of the step part, under the action of the roller extrusion pressing film, the compressibility of the gas, the rest part of the gas in the dead angle area can be concentrated in the dead angle space between the side end surface of the step part and the unit surface communicated with the gas containing holes, thus, the diaphragm can be smoothly attached to the plate and the step geometric area thereof, and a relatively complete film attaching effect can be achieved, and can effectively avoid the defect that the diaphragm is adhered to the surface of the plate to generate bubbles due to gas residue.
