Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The method of round knife blade of the present invention is not curled and passivated in the process of cutting and slitting is as follows: Figure 4 As shown in the longitudinal sectional view, in the process of cutting and slitting, always keep the wheel knife blade piercing the epoxy resin 2 and glass cloth base 1 of the prepreg 3 that is in contact with the wheel knife blade 15, only piercing The epoxy resin 12 that does not pierce the semi-curing agent that is in contact with the roller, so that the blade 15 of the wheel cutter does not contact the roller during the cutting and slitting process, thereby ensuring that the blade 15 of the wheel cutter will not curl Passivation, keeping sharp while taking advantage of the brittle nature of the prepreg epoxy, after the prepreg epoxy 2 and glass cloth base 1 are cut and the pre...

Abstract

The invention relates to the technical field associated with cutting equipment, in particular to cutting equipment and a cutting method for cutting prepregs. The cutting equipment comprises a bearing device for bearing the prepregs and a cutter feeding device for cutting the prepregs along the vertical direction of the bearing device, wherein the cutter feeding device comprises a transmission mechanism and a cutting mechanism connected with the transmission mechanism; and a fine adjustment mechanism for controlling the cutter feeding device to move along the vertical direction of the bearing device is arranged between the transmission mechanism and the cutting mechanism. The cutting equipment and the cutting method have the advantages that: the wear of a cutting edge of a cutting tool is avoided in the cutting of the prepregs; the cut width of the cut prepregs is small; the cutting size accuracy is high; edge scattering that leads to cut edge quality deterioration is avoided; crushed fine semi-solidified resin and resin glass fiber dust are reduced and even eliminated; the sanitation of the working environment is improved; and the body health of operators and the cleanness of cutting workshops are improved.

Description

technical field [0001] The present invention relates to the relevant technical field of cutting equipment, in particular to a cutting equipment and a cutting method for cutting prepreg. Background technique [0002] Common rigid printed circuit boards (PCB) and copper clad laminates (CCL) are basically epoxy resin glass cloth-based double-sided printed circuit boards, such as figure 1 As shown, the substrate used is made of glass cloth base 1 (usually used for double-sided and multi-layer), pre-impregnated with epoxy resin or other resin with semi-curing agent, and the epoxy resin of semi-curing agent is cured after rolling On both sides 2, 12 of the glass cloth base, a thinner (0.02-0.5mm in thickness) semi-cured resin glass fiber cloth (prepreg p.p) substrate 3 is formed. Then, through the PP slitting and cutting machine, the pieces are cut into the required size. Its cutting process is as figure 2 shown. The semi-cured resin glass fiber cloth base sheet 3 passes thro...
