Roll-to-roll printing electronic ink-jet processing platform based on air floating roller support

Abstract

The invention discloses a roll-to-roll printing electronic ink-jet processing platform based on an air floating roller support. According to the processing platform, an rolling mechanism (1), a tension adjusting mechanism (2), a static air floating roller (4), a tension detecting mechanism (5) and a unrolling mechanism (6) are mounted on the same bottom plate (7C) from right to left successively.A nozzle mounting mechanism is fixed above the static air floating roller. The processing platform replaces a conventional rotating roller by the static air floating roller, generates a gas film between a porous cylinder body and a flexible film, separates the film from the porous cylinder body, eliminates the position error of the film caused by the processing error and assembly error of the rotating drum, and improves the printing accuracy of printing electronic ink-jet printing.

Description

technical field [0001] The present invention relates to the technical field of roll-to-roll printed electronics, and more particularly refers to a roll-to-roll printed electronic inkjet processing platform with the function of air support. Background technique [0002] In the field of roll-to-roll printed electronics technology, printed electronics technology needs to be able to print functional devices with multi-layer structural characteristics. For such devices, the registration accuracy (Overlay Accuracy) between layers is very important. The level of registration accuracy will directly affect the performance of electronic devices. To print such devices, a precision alignment system is required to achieve layer-to-layer registration. In today's high-end printed electronic devices, an ultra-precise alignment system is indispensable and increasingly important. [0003] In the multi-layer printing unit of existing roll-to-roll printed electronic equipment, the roller play...

AI Technical Summary

Problems solved by technology

The platform of the present invention adopts modular design of each mechanism, and on the other hand, two static air-floating support rollers are used to replace the traditional rotating roller, so as to solve the problem of the processing error and assembly error of the rotating roller itself when the traditional rotating roller is in contact with the flexible film. Film position accuracy is negatively affected
