چکیده انگلیسی
In order to improve the performance of the piezoelectric micro jetting dispenser used in opto-electronic packaging industry, a new structure of the needle with a pin joint is suggested. Dynamic characteristics of the proposed micro jetting dispenser has been improved because the needle can swing around the joint and motion interference between the needle and the guiding part is decreased with the new structure. Compared with the original dispenser, the needle stroke of the proposed dispenser is increased 1.8 times, and the velocity of the needle increased 1.4 times. The jet performance is also improved. Adhesives with viscosity of 1.8âPaâs are jetted by the new micro dispenser smoothly. The mathematical models and dynamics simulation model are established. The tested results agree with the simulation ones, which proves that the models and the structure of the proposed dispenser are reliable.
