20090056114 | NOZZLE MECHANISM, MOUNTING HEAD AND ELECTRONIC COMPONENT MOUNTING APPARATUS - In an electronic component mounting apparatus, nozzle mechanisms are formed slender by providing shaft-type linear motors vertically upward of nozzle units and providing linear encoders vertical upward of the shaft-type linear motors, respectively. Thus, it becomes implementable to reduce the occupational area of the individual nozzle mechanisms in XY directions (horizontal direction), allowing the pitch of neighboring nozzles to be narrowed. It also becomes achievable to keep up with increasingly narrowing mounting pitches of electronic components in boards of increasingly smaller-size and higher-integration. | 03-05-2009 |
