摘要：According to the requirements of hot indium sealing process for the sealing of alloys and quartz glasses, the basic functions of a hot-sealing system including temperature and force control are determined. An automatic indium-sealing device is developed, and the temperature control is using phase-shift trigger for thyristor. Impedance control strategy is adopted for force control, and force control is realized by the precise moving of the heating components driven by a linear stepping motor. Control software based on LabVIEW is developed by adopting modularization programming method, and multithread technology is utilized to process multi-task. Practical application proves that the system can realize precise temperature and force control with high automation as well as the stable product consistency. ?2010 IEEE.
