Benefits of technology

[0015] In another general aspect, the invention features a dispensing system 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 motor coupled to an output drive mechanism, a dispensing unit having a material outlet from which the material is dispensed, the dispensing unit having a dispensing mechanism coupled to the material outlet, and means for removably coupling the motor unit to the dispensing unit such that operation of the motor causes the dispensing mechanism to dispense material through the outlet.

Problems solved by technology

These dispensing systems typically are only able to dispense one material at a time, and the throughput of product in these systems may be less than desired because of the time required to dispense multiple materials serially using one dispensing head.
This solution is expensive since two complete machines are used, and since additional manufacturing space is required.

Embodiment Construction

[0030] For purposes of illustration, embodiments of the present invention will now be described with reference to dispensing units designed for use with a multiple head dispensing system 10, shown in FIG. 1 and described below and in co-pending U.S. patent application Ser. Nos. 09 / 033,022, and 09 / 189,014, both of which are assigned to the assignee of the present application, Speedline Technologies, Inc. Those skilled in the art will appreciate that embodiments of the present invention are not limited for use with multiple head dispensing systems, but also may be used in single head applications as well.

[0031] The multiple head dispensing system 10 will now be described with reference to FIGS. 1 and 2. FIG. 1 shows a perspective view of a multiple head dispensing system 10, and FIG. 2 shows a top view of the dispensing system 10. For ease of illustration, the system is shown in FIGS. 1 and 2 without an outer covering.

[0032] The dispensing system 10 includes a lower compartment 12 t...

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.

Description

RELATED APPLICATIONS [0001] This application is a continuation in part of U.S. patent applications Ser. Nos. 09 / 033,022, and 09 / 189,014 both of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates generally to an apparatus and method for performing a plurality of work operations in parallel using a plurality of work devices within one workstation. More specifically, the present invention relates to an apparatus and method for dispensing material onto a substrate using one or more dispensing heads in a dispensing system. BACKGROUND OF THE INVENTION [0003] There are several types of prior art dispensing systems used for dispensing metered amounts of liquid or paste for a variety of applications. One such application is in the assembly of printed circuit boards and integrated circuit chips. In this application, dispensing systems are used in the process of encapsulating integrated circuits with an encapsulating material and in the proce...
