In Fig. 2, the MPU 100 includes a program for determining whether or not a defective is made according to the detection result of the wires 12 and 12P. Referring to Figure 1, the operation of the wire 12, 12P inspection device of the housing pins 122, 122P according to the present invention will be described.

First, the first and second jigs 126 and 126P are placed in an open state so that the housing pins 122 and 122P reach a predetermined target position (step 22). Next, the housing pins 122 and 122P reach a target position of the positioner 120 of the housing 14 to determine whether the first and second jigs 126 and 126P are to be driven (step 24).

When the housing pins 122 and 122P reach the target position, the positioner 120 is raised to raise the housing pins 122 and 122P (step 26).

The MPU 100 then generates a control signal to mount the wires 12, 12P of the housing pins 122, 122P of the raised housing pins 122, 122P to the first and second inspection jigs 126, 126P. (Step 28). That is, the housing 14 having the pins 122 and 122P paired with the wires 12 and 12P from the first and second jigs 126 and 126P by advancing the first and second jigs 126 and 126P. Insert and fix it.

Next, the thickness detecting sensor 20 is controlled by the control of the MPU 100 to check the thickness and the size of the housing 14 having the pins 122 and 122P of the paired wires 12 and 12P. Inspect with control (step 30). In the inspection step 30, the connector setting unit 30 selects the connector wire 12P to be inspected in one control operation by a mode command by the MPU 100, and the next one control operation is repeated by a clear command. Each time it is changed to the right / left / duplex mode, it controls the necessary connector wire 12P and returns to the original control operation mode by the reset command.

Next, the pair of wires 12 and 12P in the connecting state of the housing pins 122 and 122P of the wires 12 and 12P of the housing pins 122 and 122P mounted on the first and second jigs 126 and 126P. It is determined whether the thickness of the housing 14 including the pins 122 and 122P forming the size and the magnitude of the tensile force are good or inferior goods within the allowable range (step 32).

If there are no wires 12 and 12P of the housing pins 122 and 122P that are determined to be defective after the inspection (NO in step 32), the thickness and tensile force of the housing containing the pins 122 and 122P of the wires 12 and 12P are incorporated. The size is transmitted to the production management system via a network interface (not shown) and displayed on the display device 60 as good (step 34).

On the other hand, if it is determined that the defective product after the inspection (YES in step 32), the MPU 100 controls the positioner 120 with respect to the housing pins 122 and 122P, which are end portions of the wires 12 and 12P, so that the corresponding wire 12 12P) reads and displays the thickness and the tension of the housing incorporating the pins 122 and 122P as poor (step 36). That is, the thickness and tensile force of the housing containing the pins 122 and 122P of the read wire pairs 12 and 12P are transmitted to the production management system through a network interface (not shown).

Next, marked as good on the display device 60 (step 34), the pair of pins 122 and 122P of the wires 12 and 12P is the size of the thickness and tensile force of the housing in which the pins 122 and 122P are incorporated. When the inspection is completed, the wires 12 and 12P of the respective housing pins 122 and 122P are separated by reversing the first and second jigs 126 and 126P (step 38). Next, a control signal is generated by the MPU 100 to separate the wires 12 and 12P of the housing pins 122 and 122P mounted on the first and second inspection jigs 126 and 126P (step 40). Then, by lowering the positioner 120, the inspection cycle marked as good / bad on the display device 60 ends (step 42). The test cycle is repeated until the end signal is input from the user.

Therefore, the present invention, as described above, according to the housing pin inspection apparatus and method according to the present invention, since the thickness of the housing and the tension of the housing containing the pin constituting the pair of the wire can be automatically inspected, the wire and It is possible to increase the speed and precision of inspection of defective products by automatically checking the mounting state of the housing by the thickness detecting sensor, and to improve the connection state of the pins used when the pins are coupled and the diameter and tensile strength of the wires. You can get the result.

Embodiment of the present invention is for the purpose of illustration, those of ordinary skill in the art, modifications, changes, replacements will be possible through the technical scope illustrated in this specification.
