A terminal crimping apparatus is equipped with a vertically reciprocating crimper for crimping a terminal to an exposed conductive portion of an electric wire and an anvil opposing to the crimper. The crimper is vertically reciprocated by an activation device, such as a servo-motor. The apparatus has a sensor to monitor a load applied to the activation device or to monitor the height of the crimper when the terminal is crimped. A driver control for the apparatus includes a decision section comparing the monitored load or the monitored crimper height with predetermined reference data to determine whether the terminal is correctly crimped.

Method of controlling a terminal crimping apparatus

An apparatus for crimping a terminal includes a crimper vertically reciprocating to crimp electric terminals to conductors of a striped wire, and anvil opposing the crimper, and an operating mechanism for vertically reciprocating the crimper. The operating mechanism has a piston-crank apparatus to vertically reciprocate a ram attached to the crimper and a servo-motor connected to a circular plate in the piston-crank mechanism by way of a reduction gear. The operating mechanism also has a control device that stops the servo-motor for a given time period when the crimper is positioned at its lowest position to prevent spring-back of the crimper material.
