Asynchronous punching process for coated conductive foam

Abstract

The invention discloses an asynchronous punching process for coated conductive foam, which includes the steps as follows: forming is carried out: conductive hot melt cloth and PU foam are passed through a limiting fixture, a heating mold and a cooling mold of a conductive foam forming machine in turn; the coated conductive foam is pulled out by a conveyor belt; the conductive foam passes through aback glue fixture, a first roller rolls up to remove a piece of release paper thereof, and a second roller drives a first release film to fit the conductive foam; a first asynchronous motor rolls upthe first release film; a second asynchronous motor drives a second release film to fit the conductive foam; a punching machine punches the conductive foam according to the product characteristic demand; and a synchronous motor coils the finished conductive foam after punching. The original step-by-step coating forming replaced by the online integrated forming, and through conveying, punching andasynchronous winding, the difficulty that coated conductive foam cannot be wound in a traceless way and cannot be batch-grasped and pasted for SMT use is solved. The process loss, raw material loss and leftover material loss are greatly reduced, and the efficiency of production and assembly is improved.

Description

technical field [0001] The invention relates to the field of conductive foam, in particular to an asynchronous punching process of coated conductive foam. Background technique [0002] With the development of science and technology, the design of EMI EMC electronic products tends to be miniaturized, integrated and modularized. The first problem that electronics needs to solve is the problem of volume integration and miniaturization. The growth of early consumer electronics mainly came from traditional TVs, notebook computers and other products. With the renewal of the concept of personal consumer electronics, traditional consumer electronics products have entered a relatively stable development stage, while smart phones and tablet computers have become new growth engines for the entire consumer electronics market. Since this type of electronic product has the characteristics of compact structure, many components and high integration, the mutual interference between compone...

Problems solved by technology

[0003] At present, due to factors such as technology, equipment, materials, and product structural characteristics, the coated conductive foam cannot be crease-free and rolled into rolls for customers to use automatically.

Due to the inability to achieve crease-free winding, the production process requires a lot of labor, manual typesetting and low production efficiency, and the market supply is insufficient

At present, due to the accelerated update cycle of electronic products, in the installation and use of coated conductive foam, most of them are manually pasted by a large number of personnel, resulting in low efficiency.
