Hereinafter, the operation and effect of the present invention by the above configuration will be described in detail.

In FIG. 2, the control unit 22 controls the detection operation of the lead bending state of the inspection target part and the inspection operation of defects in accordance with the key signal from the key input unit 24. FIG. That is, under the control of the controller 22, the motor driving unit 25 operates and stops the servo motor 26, and the indexing drive 27 to which the servo motor 26 is connected to the entrance side is connected to the servo motor ( At each operation (for example, every one revolution) of 26, the exit side is rotated at a constant angle, thereby rotating the pitch wheel 32 connected to the exit side by one pitch. That is, in the configuration as shown in FIG. 3, the pitch wheel 32 is rotated by one pitch by a predetermined time unit by the driving of the servo motor 26 and the indexing drive 27 to transfer the tapered part 33. Each time the pitch wheel 32 transfers a pitch, the fraser bar 34 and the component inspection device 33 contact the lead wires of the taped components as shown in FIG. 3, thereby inspecting the components. In the above, for example, the lead bending state detection operation of the component, the fiber sensor 31 is installed at a position capable of detecting the lead wire of the steady state component, the fire sensor 31 is the ON signal if the steady state component When the lead wire of the part is bent, the fiber sensor 31 is out of the correct position, and thus the fiber sensor 31 cannot detect the lead wire of the part, thereby outputting an off signal.

Then, under the control of the control unit 22, the measurement unit 23 inspects the inspection target part and outputs the result to the control unit 23, and the control unit 22 receives the result data from the measurement unit 23. Displayed on the display unit 21.

The test pattern signal is applied to the inspection target part by the control from the measurement unit 23, and the result is measured by the probe 29 and the measurement jig unit 28 which are in contact with the lead wire of the inspection target part. It is input to the unit 23. Then, the measurement signal from the fiber sensor 31 for detecting the lead bending state of the inspection target component is amplified through the amplifier 30 and input to the measurement unit 23. The measurement unit 23 performs signal processing (A / D conversion) on the lead bending measurement signal input from the amplification unit 30 and the positive and negative inspection signals input from the measurement jig unit 28 to measure the measured data. It outputs to the control part 22.

An example of a control method of the controller 22 will be described below with reference to the flowchart of FIG. 4.

First, when the power is turned on or the operation of the sequencer and the component inspection device is started by the start signal, the controller 22 initializes each device (S41), and can be compared with the measurement signal which is a result of inspecting the inspection target part. The standard data is input (S42).

When the preparation operation as described above is completed, first output a control signal to the motor driving unit 25 to rotate the pitch wheel 32 by one pitch (S43), and when the inspection target part is transferred to the inspection position by the operation, The inspection device 33 and the fraser bar 34 come into contact with the inspection target part and inspect the quantity, part inspection and lead bending state of the part. First, the detection signal from the fiber sensor 31 is amplified by the amplification unit 30, is signal processed by the measuring unit 23, and then applied to the control unit 22, and the control unit 22 checks this signal, 여부 Determine whether it is a part. For example, if the signal from the fiber sensor 31 is an on signal, the inspection target part is judged to be normal, and if an off signal is input, the lead wire is determined to be a bent part. If it is determined in the step that the lead of the component is in the 휜 state, it is controlled to output an error signal to inform the operator that the lead wire of the component (S46), the sequencer is stopped (S47). Then, the replacement of the defective part by the operator is made (S48), and when the start signal is input (S49), the process returns to the first stage and the component inspection operation of the next inspection target part is started. The start signal may be generated by the operator operating the start key of the key input unit 24 after replacing the defective part.

On the other hand, if it is determined that the normal part in the lead bending determination step (S44), it is checked through the probe 29 and the measuring jig part 28 to check whether the measured value and the standard difference set in the initialization step is the same (S45). ). That is, by checking whether the parts are good or defective, and if it is determined that the failure, outputs an error (S46), and informs the operator that the bad parts have occurred, stop the sequencer (S47) to perform the replacement operation of the bad parts. (S48). On the other hand, if it is determined that the good or bad in the determination step (S45), the pitch wheel 32 is rotated one pitch, the next part is transferred to the inspection position, and the inspection operation is repeated.

As described above, the present invention allows the lead wire to detect the pinned part in the sequencer, so that the component having the conventional pin lead wire is used in the assembling process as it is, thereby improving the occurrence of errors during assembly and increasing the efficiency of the assembling process. will be.
