PP sheet cutting equipment and method thereof

Abstract

The invention relates to PP film (prepreg film) cutting equipment and a method thereof. The cutting equipment comprises a main frame with a PP film transmission mechanism, a worktable arranged on the main frame, a feeding mechanism arranged on the upper stream of the worktable and a human-computer interaction interface control system. The worktable comprises a laser and a cutting head for receiving a laser beam output by the laser and forming a cutting light beam. Through the structure, the integral PP film laser cutting equipment is provided to avoid the phenomena of powder removal and silk removal in the cutting process, realize automatic cutting and reduce production cost.

Description

【Technical field】 [0001] The invention relates to a cutting device and a method thereof, in particular to a PP sheet (prepreg film) cutting device. 【Background technique】 [0002] The circuit board is composed of multi-layer copper foil wires and an insulating carrier between the copper foil wires. This carrier is a PP sheet (Prepreg film). In the process of manufacturing circuit boards, it is generally necessary to cut PP sheets. [0003] see figure 1 , PP sheet is made up of glass fibers or other fibers 91 and colloid (for example, resin) 92 . At present, the cutting method of PP sheet is mainly: placing the rolled PP sheet on special equipment, and then cutting the PP sheet into a certain shape with a blade. During the cutting process, powder removal (crushed rubber powder) and wire removal (fiber strands) will occur at the incision position of the PP sheet. [0004] see figure 2 , These powders and filaments tend to be caught in the circuit board, causing the gap b...
