Embodiment 1

[0029] like 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 be rotated, and specifically, one of the conveying rollers 11 is coaxial on one of the conveying rollers 11 A conveying drive wheel 12 is provided. The conveying drive wheel 12 is connected with a conveying motor through a belt, and the conveying drive wheel 12 is driven to rotate by the conveying motor to drive the conveying roller 11 to rotate. 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 conveyor belt 14 is rotated by the conveyor roller 11 to drive the conveyor belt 14 to rotate to realize the conveying of the workpiece, and the conveyor be...

Embodiment 2

[0051] This embodiment 2 provides a production process of a single-sided film-coated board conveying system for circuit board production, wherein fixing a single-sided film-coated board conveying system for circuit board production is the same as that of 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 into the feeding box 21; 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 suction film spring 53 to the lower limit ring 523 is in contact with the bottom end surface of the installation groove 143; the grinding roller 31 starts to rotate and drives the grinding belt 32 to rotate, so that the grinding belt 32 grinds the upper surface of the workpiece; the grinding debris f...

Abstract

The present 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 its production process, wherein a single-sided film-coated board conveying system for circuit board production includes: each There are a number of evenly distributed push blocks fixedly connected to the conveying roller; a number of through holes are evenly opened on the conveyor belt; a number of suction film parts, each suction film part corresponds to each through hole, when the workpiece is polished by the grinding part, the suction part The suction film part stretches, and the suction part absorbs the workpiece through the suction film part; when the workpiece is transported to the position where the conveying roller at the tail first contacts the conveyor belt, the push block squeezes the film suction part to make the film suction part suck Hold the protective film on the lower surface of the workpiece; when the suction film part of the protective film on the lower surface of the workpiece follows the conveyor belt and continues to rotate, the protective film is separated from the workpiece; The protective film on the film-absorbing part is offset by the discharge port of the feeding part, so that the protective film is separated from the film-absorbing 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 inner-layer PCB layout, the two-layer circuit of the middlemost core board (Core) must be made first. After the copper clad laminate is cleaned, a layer of photosensitive film will be covered on the surface. This film will be cured when exposed to light, forming a protective film on the copper foil of the copper clad laminate...
