At the same time, 13 accurately sends out a crimping abnormality detection signal for emergency stop of the crimping line L to the operation panel 5A via the signal line 15.
Upon receiving this signal, the operation panel 5A causes an emergency stop function such as a relay (not shown) to actuate the crimping machine 4A in an emergency manner and all the devices in the crimping line L. The operator confirms that the cause of the crimping line L stop is due to the occurrence of the terminal crimping abnormality, immediately removes and removes the element with the terminal crimping abnormality, and then operates the reset mechanism (not shown) of the operation panel 5A to produce the element. To resume.

ることができる。As described above, according to the present invention, abnormal crimping of terminals that may occur when crimping a metal terminal to an end of an electric wire with an automatic terminal crimping machine in order to produce a wiring element is performed. , The position detection sensor installed in the terminal crimping jig and the position detection reference jig detect it, and the terminal crimping abnormality detection unit detects it. Since the crimping machine is configured to stop in an emergency and to notify by an alarm unit, the production efficiency of crimping the terminal to the wiring element is hardly reduced,
In addition, it is possible to completely prevent the terminal crimping abnormal element from entering and flowing out to the product, which reduces the visual inspection man-hours of the terminal crimping element, and also prevents the product from being overlooked due to the oversight of the terminal abnormal crimping in the conventional visual inspection. It is possible to prevent the occurrence of functional malfunctions of the equipment caused by the repair or the mixing of the terminal crimping abnormal element, and to prevent the occurrence of user complaints.
