Publication number: 20020007227Abstract: Embodiments of the present invention provide a multiple head dispensing system having independently controlled dispensing heads. Each of the dispensing heads may be independently controlled to provide simultaneous, asynchronous operation and to allow dispensing of different materials onto substrates. Independent control of the dispensing heads is accomplished under the control of a controller in conjunction with a plurality of gantry systems, each of which positions one of the multiple dispensing heads over a substrate that is to receive dispensing material. In some embodiments, each gantry system utilizes two drive mechanisms, arranged in parallel, that provide movement of the dispensing head over an x-y plane. Multiple conveyor systems are utilized that allow parallel processing of work products in the dispensing system.Type: ApplicationFiled: February 21, 2001Publication date: January 17, 2002Inventors: Thomas C.
