Embodiment 1

[0029] Such as Figure 1 to Figure 6As shown, this embodiment provides a single-sided film-coated board conveying system for circuit board production, including: two conveying rollers 11, and one of the conveying rollers 11 can rotate, specifically, coaxial on one of the conveying rollers 11 A conveying driving wheel 12 is provided, and the conveying driving wheel 12 is connected with a conveying motor through a belt, and the conveying driving wheel 12 is driven to rotate by the conveying motor so as to drive the conveying roller 11 to rotate, and each conveying roller 11 is fixedly connected with a number of evenly distributed Pushing blocks 13, specifically, each pushing block 13 is evenly arranged in a row along the axial direction of the conveying roller 11, and each row of pushing blocks 13 is evenly arranged along the circumferential direction of the conveying roller 11; The belt 14 is driven by the rotation of the conveyor roller 11 to rotate the conveyor belt 14 so as ...

Embodiment 2

[0051] This embodiment 2 provides a production process of a single-sided film-coated board conveying system for circuit board production, wherein a single-sided film-coated board conveying system for circuit board production is fixed as in embodiment 1, and will not be repeated here.

[0052] A specific production process of a single-sided film-coated board conveying system for circuit board production is as follows, the workpieces are sequentially placed in the feeding box 21; the workpieces slide down along the feeding slide rail 22 and feeding guide block 23 to the conveyor On the belt 14; the conveying roller 11 rotates to drive the conveying belt 14 to rotate, so that the workpiece is conveyed to the bottom of the grinding belt 32; the conveying roller 11 stops rotating; the adsorption air pump 42 works, and the suction film lower sleeve 52 is drawn by the adsorption air cover 41 to stretch Suction film spring 53 to the lower limit ring 523 and the bottom end surface of in...

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] ...
