Filed: 2001-03-02
Abstract: PROBLEM TO BE SOLVED: To easily predict a bending life in which a conductor part of core wire disconnects, before an insulating layer which is a coating material actually cracks. SOLUTION: A bending life, in which an electric wire or the like comprising a central conductor at least at its center comes to disconnect through bending, is predicted.

Title: Electric component mounting system
Inventor: SUHARA SHINSUKE
IPC: H05K13/04
Filed: 2001-03-07
Abstract: PROBLEM TO BE SOLVED: To improve efficiency of mounting work in an electric component mounting system. SOLUTION: A plurality of component holding devices 140 are moved and stopped by intermittent rotation of an intermittent rotating board 126 to suck and mount electric components. A suction nozzle 210 is held by a nozzle holding member 202 of each device 140. An engaging member 262 provided at a suction nozzle selection position is engaged on an engaging groove 260 of the member 202, and the member 202 is rotated to position a desired suction nozzle 210 at a working position. By connecting the member 262 to a rotating member 252 by an Oldham's coupling, the rotation of a nozzle selecting motor 282 can be transmitted while allowing the relative movement of the member 262 in a circumferential direction on a turning locus of the member 202. The rotation can be transmitted to the member 202 even after the member 202 starts rotation from the suction nozzle selection position, and thus, a stop time of the member 202 can be shortened while securing a time required for selecting a nozzle.
