Component mounting device and component mounting method

摘要

When performing the device type changing operation with the change of the board type to undergo mounting, the component mounting device, which has a first mounting lane and a second mounting lane and which is structured so as to be able to select either an independent mounting mode or an alternate mounting mode, moves a mounting head of the mounting lane to and thereafter positions and fixes to a previously-set predetermined withdraw position [P] where entry of a portion of a body of an operator by way of an opening (19) formed in a protective cover (18a) can be prevented and where safety of the operator is not impaired even if a mounting head of a mounting lane on the other side has undergone collision.

1. A component mounting device comprising:
a first board conveying mechanism and a second board conveying mechanism which convey boards delivered from an upstream device in a board conveying direction and which have board holding parts for positioning and holding the boards, respectively; a first component supplying part and a second component supplying part which are provided respectively beside the first board conveying mechanism and the second board conveying mechanism and supply components to be mounted on the boards; a first component mounting mechanism and a second component mounting mechanism which take out the components with mounting heads from the first component supplying part and the second component supplying part which are provided respectively in accordance with the first board conveying mechanism and the second board conveying mechanism, and mount on the boards which are held by a board holding part of the first board conveying mechanism and a board holding part of the second board conveying mechanism; and a mounting controlling part which controls a first mounting lane composed of the first board conveying mechanism, the first component supplying part and the first component mounting mechanism and a second mounting lane composed of the second board conveying mechanism, the second component supplying part and the second component mounting mechanism; wherein, when device type changing operation is performed with change of the type of boards which are the mounted objects in one of the first mounting lane and the second mounting lane, the mounting controlling part moves the mounting head of the component mounting mechanism belonging to the mounting lanes to a withdraw position wherein the withdraw position is set at a position so that the behavior that an operator makes a part of the body or a foreign object enters through an opening part provided at a protective cover part which separates the movable area of the component mounting mechanism from the component supplying part can be blocked, and the safety of the operator is not impaired by the operation of the component mounting mechanism which belongs to the mounting lane opposite to the concerned mounting lane, and the mounting controlling part fixes a position of the mounting head to the withdraw position by a brake mechanism provided in the component mounting mechanism.
