Abstract
A component mounting condition determination method is used in a component mounter of mounting components onto a board using a mounting head having plural suction nozzles, and includes: a maximum suction component number determination step (Loop A, S11 to S16) of determining the maximum number of components to be suctioned by the mounting head so as to be greater than an upper limit of a suction power within which the suction nozzles do not drop components even when the mounting head moves at a predetermined speed; and a task determination step (S18 to S20) of determining a task which is a group of components to be mounted in one iteration of a series of operations that includes suctioning, transporting, and mounting components by the mounting head, based on the determined maximum number of components.

A component mounting condition determination method for use in a component mounter which mounts components, onto a board, using a mounting head having a plurality of suction nozzles, each of the components being one of a plurality of component types, said method comprising:
- a condition determination step of obtaining parameters regarding a suction power of each of the suction nozzles to suction the components, and determining a component mounting condition so that the suction nozzles do not drop the components when suctioning the components with the suction power specified by the obtained parameters, and
- a component mounting step of mounting the components onto the board according to the component mounting condition determined in said condition determining step, by moving the mounting head having the suction nozzles, the board being stationary from a start to an end of the mounting of the components,
- wherein said condition determination step includes
- a maximum suction component number determination step of determining, for each of the plurality of component types, a maximum number of components capable of being suctioned by the mounting head to meet a condition that the suction power of each of the suction nozzles is equal to or greater than a transportable suction power, the transportable suction power being a suction power at which the suction nozzles do not drop the components even when the mounting head moves at a predetermined speed, and
- a leakage parameter input receiving step of receiving, for each of the plurality of component types, an input of a leakage parameter which indicates a degree of an air leakage from each of the suction nozzles,
- wherein in said maximum suction component number determination step, the maximum number of components capable of being suctioned which corresponds to the received leakage parameter is determined by referring to a maximum suction component number table which indicates a correspondence between the leakage parameter and the maximum number of components capable of being suctioned by the mounting head, and
- wherein in the component mounting step, the components are mounted onto the board using the mounting head such that an equal number of or a smaller number of components are mounted than the maximum number of components capable of being suctioned determined in the maximum suction component number determination step.
