Automatic slitting machine for auxiliary material of flexible circuit board

Abstract

The invention provides an automatic slitting machine for an auxiliary material of a flexible circuit board. A slitting mechanism of the automatic slitting machine comprises a cutter shaft and cutter sets, wherein the cutter shaft can penetrate through the cutter sets to be connected with the cutter sets. The cutter sets comprise the upper cutter set and the lower cutter set. The upper cutter set is composed of a plurality of cutter set units and ring-shaped upper gaskets, wherein each ring-shaped upper gasket is arranged between two adjacent cutter set units, and each cutter set unit comprises a clamping base, an upper annular circular cutter and a snap ring. The lower cutter set is composed of a plurality of lower annular circular cutters and ring-shaped lower gaskets, wherein each ring-shaped lower gasket is arranged between two adjacent lower annular circular cutters. When the upper cutter set and the lower cutter set are pressed tightly and respectively, cutting edges of the upper annular circular cutters correspond to cutting edges of the lower annular circular cutters in sequence so that each upper annular circular cutter and the corresponding lower annular circular cutter can be vertically attached to each other. According to the automatic slitting machine for the auxiliary material of the flexible circuit board, due to the facts that the upper cutter set of the slitting mechanism is provided with the cutter set units composed of the clamping bases, the upper annular circular cutters and the snap rings and the gaskets, and the upper cutter set is used in cooperation with the lower cutter set provided with the gaskets, the slitting accuracy is higher, and the material can be slit to the extent that the minimum width of the material is 5mm.

Description

technical field [0001] The invention relates to an automatic slitting machine, in particular to an automatic slitting machine for auxiliary materials of flexible circuit boards. Background technique [0002] With the continuous development and progress of science and technology, the requirements for circuit boards are getting higher and higher, especially digital products pursue convenience and light weight. Flexible circuit boards with scrambling, ultra-thin and light weight are used as high-tech products in The field of electronics has been greatly developed and applied. At the same time, with the gradual increase of labor costs and the gradual improvement of product performance requirements, automation equipment has developed rapidly. The automation equipment for circuit board auxiliary materials such as reinforcement has sprung up like mushrooms after rain. However, with the emergence of automation equipment, the slitting equipment specially used for the roll-shaped au...

AI Technical Summary

Problems solved by technology

[0003] The slitting mechanism of the slitting machine of the prior art comprises a cutter shaft and a knife set through which the knife shaft passes through, and the knife set is as figure 1 As shown, including the upper annular circular knife 101 and the lower annular circular knife 102 whose thicknesses on both sides are fixed and the blades fit together up and down, since the thicknesses of the upper annular circular knife 101 and the lower annular circular knife 102 are fixed, according to the cutting machine Cutting stability is required, and its thickness has a certain limit, so generally only materials with a width greater than 10mm can be cut.
