A terminal crimping device is composed of an elevating crimper for crimping terminals onto the exposed conductors of cables and an anvil positioned opposite said crimper. The crimper is caused to ascend and descend by means of drive means including a servo motor. The controlling of the terminal crimping operation is done by monitoring the height of the crimper at the time of terminal crimping and the load applied to said drive means and comparing a detected load to the height with the preset reference data to determine whether the terminal crimping performance is good or not. Thus, a reliable determination whether the terminal crimping performance is good or not is performed.

Control method of terminal crimping device

A method of controlling a terminal press attaching device by providing a elevating crimper for crimping terminals onto exposed conductors of the cables, setting an anvil opposite to the crimper, and elevating the drive means including a servo motor. More specifically, the crimp height for press attached terminals is monitored, a detected height and the predetermined set value are compared to control said drive means such that the detected height is made equal to the set value. Thus, the crimp height of the terminal to be attached (or the crimper height) is automatically and easily adjusted.

A method of controlling the terminal crimping device is proposed by providing an elevating crimper for crimping terminals onto exposed conductors of cables, positioning an anvil opposite to said crimper, elevating the drive means including a servo motor. The standard value for determining whether or not the crimper height is out of conformity with the standard value, the administration value for administering the crimper height, and the decision value for determining whether or not the crimping performance is good or not on the basis of the crimper height are recorded such that an alarm is issued when the crimper height is out of conformity with said standard value, said administration value, and said decision value at the time of terminal crimping operation.

A terminal crimping device includes an elevating crimper for crimping terminals onto exposed conductors of cables and an anvil positioned opposite to said elevating crimper so that the ascend/descend of the crimper is carried out by a servo motor. The terminal crimping device further includes a height sensor for outputting a crimp height at the time of crimping said terminals, a data storage unit for storing a pressing time range for determination on whether or not terminal crimping is normal and a crimper height value for determination of said pressing time; and determining unit for time measuring the time during which an output from said height sensor is not larger than the crimper height and determining that crimping is normal if the measured time is within said pressing time range. Thus, the determination on whether or not the terminal crimping is normal can be surely made.
