태양광 모듈 제조를 위한 라미네이터의 히팅시스템 제어에 관한 연구

초록

Technology of the laminator equipment, which is the core equipment in the manufacturing process of the solar module, requires a technique of combining the uniformity of the surface temperature of the heater, the degree of vacuum, and the pressure control technology. In terms of users, solar modules tend to have high output and large area. Therefore, this paper designs, manufactures and localized laminator equipments using these core technologies. In addition, for the optimal design of a large-area(3,600mm*2,200mm) heating system to cope with the large-sized solar module, a silicone rubber heater was selected based on heater selection, heater hot wire pattern and heater placement. The proposed silicone rubber heater is a single heater with three hot wire patterns, and the heater size(1,100mm*400mm*1.5mm) is placed with 18ea heaters. As a result of the fabrication and the experiment, the target specification, the starting temperature characteristic, followed the target temperature setpoint within 30minutes. and the temperature deviation from the surface temperature setpoint is within ±2℃.
