Abstract

The invention discloses a prepreg cutting and drilling integrated device. The prepreg cutting and drilling integrated device comprises a prepreg coiling and locking mechanism, a punching mechanism, acutting mechanism and a collection mechanism. The punching mechanism and the cutting mechanism are progressive die mechanisms. The cutting mechanism and the collection mechanism are connected througha conveying mechanism. According to the prepreg cutting and drilling integrated device, the punching mechanism is additionally arranged in front of a cutting position and can complete the punching procedure before cutting. The prepreg cutting and drilling integrated device is high in punching precision, not prone to deviation and low in product rejection rate. The punching procedure is conducted before the cutting procedure. Time consumed for manually collecting and stacking plates is saved. The number of equipment purchasing types is reduced. The connection time between a slicing machine anda punching machine and the preparation time are saved. The production efficiency is improved. The production cost is lowered. The requirements for automatic production are met. The invention further discloses a machining process. The machining process is high in machining precision, efficiency and automation degree and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board production, and relates to a prepreg processing device and process, in particular to a prepreg cutting and punching integrated device and processing technology. Background technique [0002] Prepreg, also known as PP sheet, is mainly composed of resin and reinforced materials, and has been widely used in printed circuit board technology. The prepreg is a thin sheet material formed by treating a reinforced material (such as glass fiber cloth) with resin impregnation and curing to an intermediate level. It can be used as a bonding material and an interlayer insulating material for the inner conductive pattern of a multilayer printed circuit board. . Usually a multi-layer printed circuit board is formed by laminating and laminating the core board and the prepreg. The prepreg forms the wetting layer and plays the role of bonding the core board. Although it has a certain initial thicknes...
