Laser peeling and film sticking integrated device

Abstract

The invention provides a laser peeling and lamination integration device. A laser peeling and lamination integration solution is realized, the capacity use ratio of the laser peeling system can be effectively improved, and production beat requirements can be achieved. In addition, the floor space and the factory overhead of a clean room can be saved, and flexible display manufacture cost is obviously lowered. Furthermore, in the scheme of the invention, the design of double laser peeling workbenches, double flexible screen platform deck rotary plate systems and double film carrying tables is further adopted, so that whole operation is not single-line operation, working efficiency is effectively improved, and manufacture cost is lowered.

Description

technical field [0001] The invention relates to OLED flexible display manufacturing technology, in particular to an integrated device for laser peeling and film sticking. Background technique [0002] Flexible display technology is one of the important development directions of OLED in the future. It has many advantages such as ultra-light, ultra-thin, rollable, portable, and impact-resistant. The preparation methods of FOLED include Roll to Roll (roll to roll) and Sheet to Sheet (sheet to sheet). The former has undergone major equipment transformation, and it is impossible to predict the mass production time. The latter is the mainstream of current technical research, and some manufacturers have already achieved mass production. [0003] In the sheet-to-sheet process, the flexible substrate needs to be bonded to the rigid carrier, which can then be processed using conventional equipment, and finally the flexible display on the rigid carrier substrate is released by a lift-...

AI Technical Summary

Problems solved by technology

[0010] Among them, the laser stripping equipment is a single workpiece table, and the loading and unloading is a serial movement, and the stripping action takes about 4 seconds, which makes the utilization rate of the laser capacity low, and the excimer laser used in the existing laser stripping equipment is expensive and maintenance cost High, resulting in higher cost COO of laser stripping equipment

[0011] For flexible film lamination equipment, subject to flexible screen transmission and flexible screen film lamination process, the production cycle is about 10 seconds, which cannot meet the production line production cycle requirements

If simply increase the ratio of equipment, it will greatly increase the clean room area and factory costs
