Single-sided film-coated board conveying system for circuit board production and production process thereof

Abstract

The invention relates to the technical field of circuit board production, in particular to a single-face film-coated board conveying system for circuit board production and a production process thereof, and the single-face film-coated board conveying system for circuit board production is characterized in that each conveying roller is fixedly connected with a plurality of pushing blocks which are uniformly distributed; a plurality of through holes are uniformly formed in the conveying belt; the film suction parts correspond to the through holes one to one, when the workpieces are polished by the polishing parts, the adsorption parts suck the film suction parts to stretch, and the adsorption parts adsorb the workpieces through the film suction parts; when the workpiece is conveyed to the position where the conveying roller at the tail is firstly in contact with the conveying belt, the pushing block extrudes the film suction part, so that the film suction part sucks a protective film on the lower surface of the workpiece under negative pressure; when the film suction part for sucking the protective film on the lower surface of the workpiece continuously rotates along with the conveying belt, the protective film is separated from the workpiece; and when the protective film is conveyed to the conveying roller at the head part and is separated from the conveying belt, the protective film adsorbed on the film adsorption part is propped against the discharge hole of the feeding part, so that the protective film is separated from the film adsorption part.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a single-sided film-coated board conveying system for circuit board production and a production process thereof. Background technique [0002] The production of PCB is very complicated. Taking a four-layer printed board as an example, the production process mainly includes PCB layout, core board production, inner layer PCB layout transfer, core board drilling and inspection, lamination, drilling, hole wall Copper chemical precipitation, outer layer PCB layout transfer, outer layer PCB etching and other steps. [0003] When transferring the layout of the inner layer PCB, first make the two-layer circuit of the middle core board (Core). After the copper clad board is cleaned, a layer of photosensitive film will be covered on the surface. This film will cure when exposed to light, forming a protective film on the copper foil of the copper clad laminate. [0004] ...

AI Technical Summary

Problems solved by technology

[0005] Traditionally, grinding machines and film tearing machines need to be provided at the same time for corresponding operations. The purchase cost of equipment is high, and the production process of circuit boards is complicated, which is easy to cause damage to circuit boards.
