SUBSTRATE STOPPING POSITION DETERMINATION METHOD AND SUBSTRATE STOPPING POSITION DETERMINATION DEVICE

摘要

A substrate stopping position determination method of an electronic component mounting machine, is provided with a movement time calculation step of calculating movement times in which two mounting heads move in order to mount electronic components when a first substrate is positioned in a first side and a second substrate is positioned in a second side, an interference loss time calculation step of calculating an interference loss time in which, while one of the two mounting heads enters an interference area, the other waits to enter the interference area, and a stopping position determination step of determining the first and the second side set position which are selected from among all combinations as substrate stopping positions based on total movement times which are calculated for all of the combinations of the first and the second side set position and the interference loss time.

1. A substrate stopping position determination method of a component mounting machine which, in order to transport first and second substrates along a conveyance direction and mount electronic components on each, is provided with first and second substrate conveyance lanes which cause the first and second substrates to stop at each set position among a plurality of first and second side set positions which are set along the conveyance direction, and first and second mounting heads which mount the electronic components of first and second component supply devices, respectively, to the first and second substrates which are stopped in each of the set positions of the first and second sides, the method comprising:
a movement time calculation step of calculating respective movement times in which the first and second mounting heads move respectively in order to mount the electronic components when the first substrate is positioned in one set position of the first side and the second substrate is positioned in one set position of the second side; an interference loss time calculation step of calculating a waiting time which is a time in which, while one of the first and second mounting heads enters an interference area, the other waits to enter the interference area as an interference loss time based on a probability that, when one of the first and second mounting heads is anticipated to enter the interference area, the other is moving within the interference area, and based on the movement time in an interference area in which there is a likelihood that the first and second mounting heads which correspond to the respective first and second substrates which are each positioned in the same set positions as in the movement time calculation step will interfere with each other; and a stopping position determination step of determining the first side set position and the second side set position which are selected from among all combinations as substrate stopping positions based on total movement times which are calculated for all of the combinations of the first side set position and the second side set position by the movement time calculation step and the interference loss time which is calculated by the interference loss time calculation step.
