In addition, as a method for determining pass / fail by image processing in each inspection apparatus, a known image processing method may be appropriately employed.

  This embodiment is configured as described above. When the crimp terminal 35 is assembled, the electrical component supply station 11 cuts one lead portion 18a of the capacitor 18 that is sequentially sent out to a predetermined length (one side). After the cutting step), the suction pipe 22 is fitted in the suction state, and the capacitor 18 is held in the suction state (electrical component suction step). In this state, the other lead portion 18b is cut to a predetermined length (the other side) Cutting process) and automatically transferred to the next process.

  In the inner conductor crimping station 12, the crimping portion 24b of the inner conductor terminal 24 is crimped to the other lead portion 18b of the attracted capacitor 18 by the movement control of the suction pipe 22 (inner conductor crimping step).

  Thereafter, the inner conductor terminal 24 is connected to one lead portion 18 a of the capacitor 18, and is automatically conveyed to the inner conductor mounting station 13 of the next process by the suction pipe 22.

  In the inner conductor mounting station 13, the attracted inner conductor terminal 24 is inserted into the mounting hole 29 a of the holder member 29 in the outer conductor terminal 27 and mounted by controlling the movement of the suction pipe 22 (inner conductor mounting). Step), after the mounting, the suction of the suction pipe 22 is released, and in the suction released state, the suction pipe 22 is retracted and returned to the second supply position F (suction means retracting step). Here, the crimp terminal 35 is assembled.

  Thereafter, the crimp terminal 35 is sent out to the outer conductor crimping station 14, and the outer conductor crimping station 14 is supplied with the co-crimp terminal 31 and supplied with the coaxial electric wire 1 peeled off in a desired state, crimped, and leaded. The portion 18a and the center conductor 1d are crimped and connected by the co-crimping terminal 31, and the first crimping piece 27f and the second crimping piece 27g of the outer conductor terminal 27 are crimped and connected to the braided layer 1c and the outer skin layer 1a, respectively. Thus, a state in which the crimp terminal 35 is crimped and connected to the end of the coaxial cable 1 is obtained (terminal crimping step).

  As described above, the assembly of the series of crimp terminals 35 in which the inner conductor terminal 24 and the capacitor 18 are assembled to the outer conductor terminal 27 can be automatically performed by the automatic conveyance control by the suction pipe 22, so that the cycle time can be improved. In addition to being excellent in productivity, cost reduction can be achieved, positioning accuracy can be improved, and product quality can be improved.

  In addition, the inner conductor terminal 24, which is a fine component, and the lead portion 18b of the capacitor 18 can be automatically crimped, so that it is not necessary to approach the hand as in manual work, and safety is improved.

  Further, since the crimp terminals 35 that are sequentially assembled are transported to the position of the outer conductor crimping station 14, the operator only needs to be at the position of the outer conductor crimping station 14, and between the stations 11, 12, 13, 14, There is no need to move across.

  In addition, in each inspection area E, G, K, the processing status is inspected by image processing, and the inspection accuracy is improved and the generation of defective products is effective compared to the case of visual inspection. There is an advantage that the quality of the product can be further improved.

  Further, when crimping the crimping terminal 35 and the coaxial cable 1, the coaxial cable 1 can be set from above, and compared with the case where the outer conductor terminal 27 is inserted from the axial direction, the crimping part 27 c and the braid The sliding contact with the layer 1c can be effectively prevented, and problems such as scattering of the braided layer 1c can be effectively avoided.

  Further, since the inner conductor guide body 33 is disposed between the inner conductor mounting position H and the second supply position F in the inner conductor mounting station 13, the holder mounted on the connection portion 27 a of the outer conductor terminal 27. When the inner conductor terminal 24 is inserted into the mounting hole 29a of the member 29, there is an advantage that the posture of the inner conductor terminal 24 can be corrected to a predetermined posture, and the inner conductor mounting process is smoothly performed.

  Further, as the suction means, the suction pipe 22 that can be fitted onto the one lead portion 18a is adopted, so that the suction state of the capacitor 18 and the like is stabilized, and the transfer operation can be performed satisfactorily.

  In the above embodiment, the inner conductor mounting station 13 and the outer conductor crimping station 14 are arranged side by side. However, the chain-like crimp terminal 35 assembled at the inner conductor mounting station 13 is wound up. It is good also as a structure which crimps | bonds the crimp terminal 35 with respect to the coaxial electric wire 1 in the outer conductor crimping station 14 arrange | positioned separately using the accommodated chain-like crimp terminal 35.

  In the coaxial cable 1, a conductive foil such as an aluminum foil may be provided on the inner periphery, the outer periphery, or both of the braided layer 1 c, and the two conductors are not necessarily disposed concentrically. There is no need, and an electric wire in which two conductors are arranged in parallel may be used. Furthermore, an electric wire provided with another conductor in addition to the two conductors may be used. That is, all the electric wires having at least two conductors are targeted for processing.

  Furthermore, although the structure using the capacitor 18 is shown as an electrical component, various electrical components having a pair of lead components such as a resistance component and a rectifying element component should be adopted according to the required electrical characteristics. Can do.
