Roll-to-roll patterning equipment based on die cutting

Abstract

The invention belongs to the technical field related to ductile circuit manufacturing, and discloses roll-to-roll patterning equipment based on die cutting. The equipment comprises an unwinding roller, a flexible belt, a die cutting mechanism, a tension detection mechanism, a stripping mechanism and a winding mechanism, wherein the unwinding roller, the die cutting mechanism, the tension detectionmechanism, the stripping mechanism and the winding mechanism are sequentially arranged at intervals; one end of the flexible belt is accommodated in the unwinding roller, and the other end of the flexible belt sequentially penetrates through the die cutting mechanism, the tension detection mechanism and the stripping mechanism to be connected to the winding mechanism; the die cutting machine is used for patterning the flexible belt; the tension detection mechanism is used for carrying out tension detection on the flexible belt and feeding back the detection results to the winding mechanism; the stripping mechanism is used for stripping the patterned flexible belt; and the winding mechanism is used for collecting a stripped finished product roll and a stripped waste product roll and adjusting the flexible belt according to the detection results, so that the tension of the flexible belt is made to be within a preset range. According to the roll-to-roll patterning equipment based on thedie cutting, the production efficiency is improved, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field related to ductile circuit production, and more specifically relates to a roll-to-roll patterning equipment based on die-cutting. Background technique [0002] In recent years, flexible devices have developed rapidly, such as epidermal sensors and flexible screens, etc. have been developed relatively maturely. Flexible devices often have strong ductility and compliance, and are easy to attach to the surface of the human body and follow the movement of the human body freely. The mechanism of action realizes many functions such as sign monitoring, motion measurement, auxiliary perception, and signal generation. In addition, its weight is often quite light, and it is quite convenient to use and store. Due to its huge application prospects, it has continued to become one of the hot issues in the scientific research community in recent years. [0003] Flexible devices are often composed of internal functional la...

Problems solved by technology

[0004] Currently commonly used patterning methods mainly include laser cutting, chemical etching, etc. These methods are more suitable for small batch production, but with the maturity of product development, the demand for flexible devices is gradually increasing, and the processing speed of these processing methods is relatively slow , the disadvantages of complex operation and high cost have gradually emerged. Among them, chemical etching and printing methods have also been applied to mass production to a certain extent, but there are still certain disadvantages that limit their development. For example, chemical etching uses corrosive materials and is easy to produce. Pollution; while the printing method is mainly aimed at liquid metal materials, the material cost is often relatively expensive, and the die-cutting scheme is also partially applied, but it still cannot be widely promoted due to waste discharge and other issues.
