Methods and devices for laminating

A laminating device, comprising:

• a first conveying device configured to convey a film-like structure;
• a second conveying device arranged along a conveying direction of the first conveying device, a conveying speed of the first conveying device being greater than that of the second conveying device, the second conveying device receiving the film-like structure conveyed by the first conveying device, the film-like structure forming a folded portion on the second conveying device;
• a laminating apparatus configured to convey an object to be laminated and receive the film-like structure conveyed by the second conveying device, wherein the film-like structure with the folded portion is laminated with the object to be laminated on the laminating apparatus;
• and
• a plurality of suction assemblies, wherein the plurality of suction assemblies are distributed at intervals on a conveying surface of the second conveying device, and two adjacent suction assemblies respectively suction the film-like structure so that the film-like structure forms the folded portion between the two adjacent suction assemblies.
