The flux applying device 7 has a flux tank in which a flux liquid is stored in place of the stripping liquid in the same stripping liquid tank 51 of the stripping apparatus 5. Other configurations are the same as those of the peeling device 5 described above. By operating the coil lowering air cylinder, the air core coil C is lowered to a predetermined position, and the coil terminal C0 is immersed in the flux liquid in the raised bucket for a predetermined time. Thus, the flux is adhered to the portion of the coil terminal C0 where the insulating coating has been peeled off.

The pre-soldering device 8 has the same structure as the flux applying device 7 except that a solder bath containing molten solder is provided instead of the flux liquid. The air cylinder for lowering the coil is operated to lower the air core coil C to a predetermined position, and the coil terminal C0 is immersed in the solder in the raised bucket for a predetermined time. Thus, the coil terminal C
A preliminary solder is adhered to 0.

The control device 9 comprises a sequence controller, and controls the drive motor 28, the air cylinders 54, 57, 61 and the like based on signals sent from positioning sensors and switches (not shown). When each coil holding unit 3 reaches a predetermined position in the cutting device 3 or the peeling device 4, the control device 9 stops the transfer, and then performs a cutting operation or a peeling operation in the cutting device 3 or the peeling device 4. When the operation is completed, the next coil holding unit 3 is transferred until it reaches a predetermined position. Therefore, in each device such as the cutting device 3, the processing of the coil terminal C0 is performed in parallel.

When the coil C is removed from the coil holding unit 3, the air cylinder 111 for moving back and forth is operated to bring the locking claw 119 close to the coil holding unit 3 as shown by a solid line in FIG. Thereafter, the air cylinder 116 for vertical movement is operated to lower the locking claw 119 to the position shown by the dashed line in FIG. Then, if the cylinder rod is retracted by operating the air cylinder 111 for moving back and forth, the coil C is moved from the locking pin 37 onto the magazine rod 121 by the locking claw 119. When the number of the coils C reaches a predetermined number, the coil C is detached from the magazine rod 121.
