摘要:
The invention provides a mounting apparatus with a beam (6) which is free from adverse effect on its performance due to thermal distortion and misalignment of its guide rails, on which the beam (6) for mounting operation travels. One end of the beam (6) is rotatably supported on a slide, which moves along the guide rails. Another end of the beam (6) is also rotatably supported on another slider through a moving element (47). The slider and the mounting element (47) move along the guide rail. The moving element (47) moves in a direction perpendicular to the guide rails.

An electronic component mounting apparatus has a pair of guides (8), a beam (6) travelling along the guides (8) and a mounting head placed on the beam (6). A first linear (7) motor moves the beam (6) along the guides (8), and a second linear motor moves the mounting head along the beam (6). A thermal insulating portion placed between the beam (6) and the guides (8) thermally insulates the two components from each other. Thermal conduction portions (16, 41) are placed on the fixed elements (12) of the first (7) and second linear motors. This configuration assures an accurate operation of the mounting apparatus by eliminating thermal deformations of their components.
摘要:
A component-mounting block of an electronic component-mounting apparatus has mounting heads installed thereon. Each mounting head has a nozzle-replacing device for replacing at least one selected sucking nozzle by at least one other sucking nozzle to be newly selected. The replacement is possible during travel of the component-mounting block between a mounting position and a sucking position effected by a X-Y moving stage. At least one mounting head carries at least one sucking nozzle rotatable about a vertical axis of a nozzle holder. The mounting head has the nozzle holder, and an engaging member holder. Sucking nozzles are circumferentially arranged about the vertical axis of the nozzle holder and vertically retractably held by the nozzle holder. The engaging member holder holds engaging members which engageably face the nozzles. The nozzles are engaged with the engaging members when the holders are relatively vertically moved toward each other, and are retracted when the holders are moved away from each other. The engagement can be prevented. A selected engaging member is prevented from engaging with a corresponding sucking nozzle by rotating the holders about the vertical axis. Alternatively, at least one nozzle is disengaged from a corresponding engaging member at a desired rotational angle of the holders.

A pallet-storing block of an electronic component-mounting apparatus stores a plurality of pallets each carrying thereon a tray containing a large number of electronic components. A desired pallet selected from the pallets is moved along a transfer path, in a manner such that the desired pallet is advanced to be introduced into a pickup area which extends to cover almost all of the transfer path or withdrawn from the pickup area into the pallet-storing block. Desired electronic components are sequentially picked up from the desired pallet introduced into the pickup area and mounted on a circuit board. The desired pallet is moved to a desired position within the pickup area.
摘要:
A main block of an electronic component-mounting apparatus has a first side parallel to a transfer passage for transferring a circuit board, a second side perpendicular to the first side, and a pickup area to which electronic components are supplied for being picked up. A first electronic component-feeding block is arranged on the first side, and includes a plurality of feeders arranged in parallel with each other for directly feeding a plurality of types of electronic components, respectively, to the pickup area. A second electronic component-feeding block is arranged on the second side, and includes a plurality of trays each carrying a number of electronic components thereon, and selectively bringing the plurality of trays to the pickup area to thereby supply a plurality of types of electronic components to the pickup area.
