Abstract

A work machine and a mounting method by which end portions of a wire member can be mounted on connecting sections which are arranged variously are provided. A work head includes a first holding section configured to hold a first end portion and a second holding section configured to hold a second end portion. A control device includes a first mounting section configured to mount the first end portion held by the first holding section on a first connecting section, a moving section configured to cause a work head moving device to move the work head in accordance with a position of the second connecting section after having mounted the first end portion on the first connecting section, and a second mounting section configured to mount the second end portion held by the second holding section on a second connecting section.

Dependent claims

A work machine comprising:

a substrate holding device including a clamp configured to hold a circuit substrate including a first connecting section and a second connecting section on a first surface of the circuit substrate;
a work head configured to hold a wire member including a first end portion and a second end portion so as to mount the wire member on the circuit substrate held by the substrate holding device;
a work head moving device configured to move the work head, the work head including a first chuck configured to hold the first end portion;
and a second chuck configured to hold the second end portion;
and
a control device configured to
mount the first end portion, being held by the first chuck, on the first connecting section;
determine multiple paths of the wire member to be bent between the first connecting section and the second connecting section so as to avoid contacting a component mounted on the first surface of the circuit substrate;
select a path out of the multiple paths based on a predetermined criteria;
cause the work head moving device to move the work head in accordance with a position of the component and a position of the second connecting section after having mounted the first end portion on the first connecting section based on the path;
and
mount the second end portion, being held by the second chuck, on the second connecting section.
