Coiled material supply device for flexible circuit board production

Abstract

The invention relates to a coiled material supply device for flexible circuit board production. The coiled material supply device comprises a support plate, a coiled material support mechanism, a first guide roller, a coiled material splicing mechanism, a group of flat steel plates, a coiled material thickness detection mechanism, a second guide roller and a tension control mechanism, wherein the coiled material support mechanism comprises an air expansion shaft which is rotationally mounted on the support plate; the first guide roller is positioned above the front side of the air expansion shaft; the coiled material splicing mechanism is arranged at the rear side of the first guide roller; the group of flat steel plates are detachably connected to two sides of the upper surface of a fixing part of the coiled material splicing mechanism through bolts; the coiled material thickness detection mechanism is arranged below the rear side of the fixing part and is used for detecting the residual thickness of the coiled material; the second guide roller is located at the rear side of the fixing part, and a third guide roller set which is arranged up and down is rotationally mounted at the upper part of the second guide roller; and the tension control mechanism is arranged at the upper side of the fixing part of the coiled material splicing mechanism. The coiled material supply device is compact in structure and small in occupied space; the splicing precision can be effectively improved, so that rapid and accurate splicing of new / old coiled materials is realized; and the offset when the new coiled material is output can be effectively reduced.

Description

technical field [0001] The invention relates to a coil material supply device for flexible circuit board production, which is mainly used for coil material supply in the printing process of flexible circuit boards. Background technique [0002] Flexible circuit board is a highly reliable flexible printed circuit board made of polyimide, polyester film, ribbon, flexible cloth and coated paper. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. The coil supply device is the basis of the circuit board printing and processing production line, and the circuit board printing efficiency, printing effect, and printing quality are greatly affected by the coil supply device. [0003] The existing coil supply device for flexible circuit board production has the following defects in the actual use process: 1) The overall structure is not compact enough, which not only leads to increased space occupation, but also increases the position...

Problems solved by technology

[0003] In the actual use of the existing coil supply device for flexible circuit board production, there are the following defects: 1) The overall structure is not compact enough, which not only leads to increased space occupation 2) When the coils are exhausted, the splicing accuracy of the new / old coils is insufficient, resulting in low splicing efficiency of the new / old coils, and when the new coils are output The position offset is large
