Description

Technical Field

[0001] The invention relates to the technical field of prepreg cutting and drilling, in particular to a prepreg automatic cutting and drilling device and method. Background Art

[0002] As the downstream application market of printed circuit boards (PCBs), such as smart phones, tablet computers and other electronic products, develops towards large-scale integration, lightweight and high intelligence, PCB production is becoming more and more precise. Prepreg automatic cutting and drilling devices are widely used in the field of circuit board production, especially for prepreg processing that requires high-precision cutting and punching. The current prepreg automatic cutting and drilling devices are often composed of a feeding mechanism, a cutting mechanism, a drilling mechanism, a dust collection mechanism and a receiving mechanism. In order to ensure the cleanliness of the working environment, the current semi-cured sheet automatic cutting and drilling device needs to clean up the scraps and debris generated during the cutting and drilling process in order to ensure the cleanliness of the working environment. The waste generated by cutting is scraps, which can be collected and reused, while the waste generated by drilling is debris dust, which cannot be utilized. The two are different in nature. Most of them are now mixed and recycled using negative pressure pipes. The existing semi-cured sheet automatic cutting and drilling device is difficult to recycle in separate ways, so that the debris dust and scraps are mixed together. The two types of waste cannot be collected independently, which will contaminate each other and affect subsequent recycling and reuse. Secondly, the existing semi-cured sheet automatic cutting and drilling device needs to use a filter to block the debris dust when collecting it. However, it is difficult to dredge the filter, so that the air permeability of the filter will decrease, which will affect the negative pressure effect, thereby reducing the debris dust recovery effect. Therefore, we propose an automatic cutting and drilling device and method for semi-cured sheets. Summary of the invention
