The welding method of the EVA film automatic placement and welding integrated machine comprises the following steps:

the glass sheet 50 is conveyed to the welding position by the conveyance normalization device 20;

the EVA film feeding device 30 cuts the EVA film onto the transfer platform 351;

the gripping sucker 443 of the transfer welding device 40 sucks the EVA film, conveys the EVA film to a preset welding position on the glass plate 50, and welds the EVA film to the preset position of the glass plate 50 by the welding component 444;

four corner welding assemblies 75 of the four corner welding 70 apparatus weld the EVA sheets at the four corners of the glass sheet 50 thereto after the glass sheet 50 is delivered to the welding location.

Preferably, three transfer platforms 351 may be provided, and the EVA film feeding device 30 places EVA films on the three transfer platforms 351, respectively. Meanwhile, a plurality of gripping suckers 443 are arranged on the transfer welding device 40, and the gripping suckers 443 grip the EVA film on the three transfer platforms 351 and then transfer the EVA film to a predetermined welding position on the glass plate 50, where the predetermined welding position is arranged in the middle of the glass plate 50. Then, three EVA sheets are welded to the glass plate 50 by the transfer welding device 40.

When the glass plate 50 is conveyed to the EVA film automatic placement and spot welding integrated machine, the EVA films are placed on the four corners of the glass plate. The EVA film at four corners is welded through the four-corner welding assemblies 75 when the EVA film is automatically placed and welded by the spot welding all-in-one machine for feeding, cutting, transferring and welding, so that the welding efficiency of the EVA film is improved.

The embodiments of the present utility model are not limited thereto, and the present utility model may be modified, substituted or combined in various other forms without departing from the basic technical spirit of the present utility model, which falls within the scope of the claims, according to the above-described aspects of the present utility model, using the general knowledge and conventional means of the art.
