Abstract:
1. An electronic component mounting system formed so that a screen printing portion for printing electronic component joint paste on boards is disposed on an upstream side of a component mounting portion for mounting electronic components on the boards, the electronic component mounting system comprising: an individual printing mechanisms, which are provided in the screen printing portion and controlled individually so that printing operations can be performed independently and setup change works due to change in print target board type can be executed individually; a board distributing portion by which printed boards conveyed out of the individual printing mechanisms are distributed to board delivery mechanisms provided in the component mounting portion in accordance with any board distribution pattern; the board delivery mechanisms which are provided in the component mounting portion to convey the boards distributed by the board distributing portion, and component mounting mechanisms which are provided in the component mounting portion to execute component mounting operations on the boards conveyed by the board delivery mechanisms; a mode instruction portion which designates a work mode indicating a mode of component mounting work to be executed by each of individual mounting lanes in multi-board mounting work in which the individual mounting lanes each composed of a combination of corresponding one of the individual printing mechanisms, corresponding one of the board delivery mechanisms and corresponding one of the component mounting mechanisms are operated to execute component mounting work on boards simultaneously and concurrently; and a control portion which controls the screen printing portion and the component mounting portion in accordance with the designated work mode; wherein the mode instruction portion selectively designates either of a first work mode in which component mounting work is continuously executed on a single board type in each individual mounting lane and a second work mode in which component mounting work is intermittently executed on a plurality of board types in one individual mounting lane while the setup change work is executed repeatedly in the individual printing mechanism of the individual mounting lane whenever the board types are changed from one to another in the individual mounting lane, so that component mounting work for the board types in the individual mounting lane and component mounting work for the single board type in another individual mounting lane are executed simultaneously and concurrently in the second work mode.
