Patent ID: 8196287

Claim:
An electronic component mounting line comprising an electronic component installation apparatus which installs an electronic component on a substrate, and a substrate inverting apparatus which is located in a downstream side of the electronic component installation apparatus and inverts the substrate having the electronic component installed thereon, wherein the electronic component installation apparatus comprises: two component installation parts having component supply parts for supplying electronic components mounted on the substrate and component installation mechanisms for taking the electronic components out of the component supply parts and transferring and installing the electronic components to the substrate, the component installation parts being placed symmetrically with respect to a line centerline of the electronic component mounting line in plan view, two substrate positioning parts which are disposed in correspondence with each of the two component installation parts and position and hold the substrate in installation work positions by the component installation mechanisms, two conveyance paths for feed which respectively feed the substrate carried from the upstream side to the downstream side, the conveyance paths for feed in which the substrate positioning parts are disposed, and a return conveyance path which returns the substrate carried from the downstream side to the upstream side and is disposed in a state of being sandwiched between the two conveyance paths for feed, wherein the substrate inverting apparatus comprises a substrate inverting unit, wherein the substrate inverting unit is joined to one of the two conveyance paths and the return conveyance path, inverts the substrate carried by the one of the two conveyance paths, and passes the inverted substrate to the return conveyance path.
