Background

In a plurality of manufacturing fields of electronic products, automobiles, medical appliances and the like, die cutting processing is a key process widely applied. The die cutting process mainly uses a die cutting machine and a die cutting tool to cut various materials (such as foam, double-sided adhesive tape, film, rubber, metal foil and the like) according to preset shapes so as to obtain required parts. These components are typically subjected to multiple layers of material to meet the performance requirements of the final product.

Traditional material bonding methods are mainly finished by manual or simple mechanical devices. For example, materials such as foam and double-sided adhesive tape are manually attached to the main material tape, respectively, and then cut. This approach has a number of drawbacks:

The production efficiency is low, the manual bonding speed is low, bonding position deviation is easy to occur, repeated adjustment is needed, and the production efficiency is seriously affected.

The product quality is unstable, the consistency of the laminating pressure is difficult to ensure by manual lamination, and flexible materials such as foam and the like are easy to deform, fold or shift, so that the quality and the appearance of the final product are influenced. Particularly, for thicker and soft materials such as foam, permanent deformation is easy to generate due to uneven stress in the attaching process.

The problems of glue overflow, unreasonable lamination and the like are easy to occur, namely, the lamination position and pressure are difficult to accurately control by manual lamination, and particularly, the problems of glue overflow, unreasonable lamination, suspended material and the like are easy to occur for lamination of multi-layer materials, so that the defective rate of products is increased.

The material scratch problem is that in the traditional attaching process, friction between the material and equipment parts easily causes surface scratch of the material, and the appearance and performance of the product are affected.
