Dispensing system and method

Abstract

A dispensing system and method for dispensing material onto a substrate. The dispensing system includes a frame, a support, coupled to the frame, that supports the substrate at a dispensing position in the dispensing system, and a dispensing head, coupled to the frame, that dispenses the material onto the substrate. The dispensing head includes a motor unit having a first motor coupled to an output drive mechanism, and a dispensing unit, removably coupled to the motor unit, having a material outlet from which the dispensing material is dispensed, the dispensing unit having a dispensing mechanism coupled to the material outlet and coupled to the output drive mechanism of the motor unit such that operation of the first motor causes the dispensing mechanism to dispense material through the outlet.

What is claimed is:  
     
         1 . A dispensing system for dispensing material onto a substrate, the dispensing system comprising: 
 a frame;    a support, coupled to the frame, that supports the substrate at a dispensing position in the dispensing system; and    a dispensing head, coupled to the frame, that dispenses the material onto the substrate, the dispensing head including: 
 a motor unit having a first motor coupled to an output drive mechanism; and  
 a dispensing unit, removably coupled to the motor unit, having a material outlet from which the dispensing material is dispensed, the dispensing unit having a dispensing mechanism coupled to the material outlet and coupled to the output drive mechanism of the motor unit such that operation of the first motor causes the dispensing mechanism to dispense material through the outlet.
