METHOD FOR CONTROLLING ACCURATE DISPENSING OF ADHESIVE DROPLETS

摘要

This device relates to the field of adhesive application more particularly to applying small amounts of adhesive to read-write slides to secure microcomponents. It is difficult to regulate the amount of adhesive dispensed when only small amounts are required, it is also difficult to accurately position these adhesive droplets on the read-write slide to secure microcomponents in the proper location. The adhesive dispensed is optically monitored using a camera (18) and monitor (16). The adhesive is dispensed through an orifice but does not contact the target surface until it is visually found to be within pre-established limits, once within these limits the adhesive is dispensed to the slide. The dispensing system also includes: a console (10), including a keyboard (12), an illuminating source (20), a dispenser (30) and a pneumatic power source (22).
