Description

Technical Field

[0001] This invention relates to the field of diaphragm processing technology, specifically to a parallel die-cutting device and method for large-size, high-precision automotive-mounted precision adhesive diaphragms. Background Technology

[0002] Currently, the die-cutting of automotive precision adhesive films mainly adopts a single-axis die-cutting method, which cuts the film to be die-cut into the required shape in one go. This method has low die-cutting efficiency, and the die-cutting accuracy is greatly affected by the quality of the die-cutting tool and the experience of the operator.

[0003] To improve the die-cutting efficiency and precision of automotive precision adhesive films, multi-axis die-cutting technology has emerged in recent years. Multi-axis die-cutting technology refers to dividing the film to be die-cut into multiple die-cutting units, and then performing die-cutting in parallel by multiple die-cutting spindles. This method can improve die-cutting efficiency and reduce the requirements for the quality of die-cutting tools and the experience of operators. However, existing multi-axis die-cutting technology has the following problems: Generally, when producing films, it is necessary to first cut the film into multiple parts and then perform die-cutting. This process makes the overall processing steps more complex and requires manual transfer and installation, which is not only time-consuming and labor-intensive but also has low production efficiency.
