Title: Component suction position teaching method in component mounting device
Inventor: KURINO GENICHIRO
IPC: H05K13/02
Filed: 2002-12-27
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently teach a suction position of a component in a component mounting device and to improve component mounting efficiency.  <P>SOLUTION: The component supplied from a component supply device is image-picked up by a recognition camera, and the suction position of the component is taught. When a component size is large, teaching is performed by performing a jog operation after the recognition camera moves to a lower left endpoint which is previously obtained from a component dimension (S6). Then, the recognition camera moves to an upper right endpoint (S9) and second teaching is performed. A center of a straight line connecting both points is taught as the suction position of the component. Since the recognition camera automatically moves to the two points which are previously obtained by calculation when teaching work is performed on the two points of the component, a distance that an operator is to move the recognition camera small by a jogging operation can be shortened, and a time required for teaching work can be shortened.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
