1o1ˉ8。 Head position Correct∶ on funcIion and residual amount detection function
This function appⅡ
es pressure to the inside of syringe to the extentthat the adhesiVe does not come out and
estimates the head position ofthe inside of syringe by rneasuring the airˉ
discharge tirne。
Based on the estimated head pos"ion,this function aut°
maticaⅡ y chaOges the dispensing pressure so thatthe
energy of Compressed引
rin the insde of sy"nge can巾
e equal and corrects the change of d⒗
pensing diameter
due to the head pos"ion.
