Infusion Bottle Automatic Electronical Micropore Leak Inspector

Application

The machine is dedicated to inspect infusion bottles for possible liquid leakage (including plastic bottles and glass bottles).

Working principle

Containers are transferred by deliver track to infeed wheel for equidistant separation. 30 divided robots take bottles constantly and turn them over 180°. After twice turn over, bottles reach different inspection station for upper and bottom inspection. After inspection, they enter outfeed wheel. Then qualified and unqualified products are discharged separately by reject unit.

Voltage principle

V is high frequency high voltage power, its two ends is separately connected with emitting electrode and receiving electrode. C₁ and C₂ are capacitance between electrode and solution (Because of the cut off by isolated bottle surface, electrode can not contact solution, then form capacitance). R is solution resistance. When no leak present on container, the generated induction current is defined as I₁. When container is leaked, the capacitance between bottle surface and electrode will disappear, capacitive reactance generated by capacitance is zero, the return circuit will generate higher current I₂. Compare the current value to judge if the container is leaked.
