Description

Technical Field

[0001] The utility model relates to the technical field of foam assembly, in particular to an automatic foam assembly device. Background Art

[0002] With the continuous development of foam technology, foams are introduced in many products to solve problems in the product production process. Foam is a material obtained by foaming plastic particles, and has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, convenient use, flexible bending, ultra-thin volume, and reliable performance.

[0003] With the development of production automation, more and more foams can now be assembled automatically. For example, the existing patent (publication number: CN210504582U) can automatically separate the foam bottom film from the foam and continuously separate it automatically, eliminating the cumbersome manual process of separating the foam from the foam bottom film, saving labor, improving work efficiency, reducing the production cost of enterprises, and meeting the needs of large-scale production of enterprises. However, the separation of its bottom film lacks effective continuous separation. When the bottom film does not form continuous separation, it is easy to cause sudden breakage or jumping of the foam when the foam moves to the foam conveying platform, resulting in chaos of the foam on the foam conveying platform. At the same time, it is also easy to cause the release paper at both ends of the foam to warp, affecting secondary processing, resulting in position deviation when pasting the foam, and thus leading to a high error rate. Summary of the Utility Model
