Abstract:
1. An electronic component mounting device that mounts an electronic component fetched from a component supplying part by a mounting head on a substrate transported by a substrate transporting mechanism and positioned at a component mounting position, the electronic component mounting device comprising: a head moving mechanism that moves the mounting head between the component supplying part and the component mounting position, two rows of transporting conveyors that constitute the substrate transporting mechanism, and that transport the substrate in a substrate transporting direction, the component mounting position set at each of the transporting conveyors; a substrate-bottom receiving mechanism which is set at the component mounting position, and which receives the positioned substrate from a lower surface side of the substrate by multiple bottom receiving pins; and a bottom receiving plate in a rectangular plate shape, which holds the bottom receiving pins in the substrate-bottom receiving mechanism such that the bottom receiving position can be adjusted; wherein the bottom receiving plate has holding parts for fetching on two side end surfaces on an upstream side and a downstream side in the substrate transporting direction, respectively, and a pivotal shaft having a longitudinal axis parallel to the substrate transporting direction and provided on each of the two side end surfaces, wherein each of the holding parts rotates around the its respective pivotal shaft; the holding parts do not protrude from an upper surface of the bottom receiving plate when the holding parts are not used; when an operator carries out the fetching operation, the holding parts protrude from the upper surface, wherein the holding parts for fetching have rod-shaped holding parts arranged on the two side end surfaces, respectively, and rotating around a horizontal pivot, wherein the two rows of transporting conveyors include a first transporting conveyor and a second transporting conveyor, and in the first transporting conveyor, the pivot is located on one end side of one of the rod-shaped holding parts, the one end side distant from the second transporting conveyor while the bottom receiving plate is installed in the substrate-bottom receiving mechanism.
