By moving in a direction parallel to the guide cutter projections 44 makes the leading end of the pin 3 by pressing the base end of the pin 3 and the step implantation implanting the workpiece (bobbin 2) in order.

  Based on the above configuration, the cutting process and the driving process of the wire 1 are performed in a state where the wire 1 to be the pin 3 is engaged with the guide cutter groove 34, so that the thin wire 1 (pin 3) is surely not bent. In addition to being cut, the cut pin 3 is reliably driven into the workpiece (bobbin 2) without bending.

  The push cutter 40 having the guide cutter projection 44 simplifies the structure of the pinning device 10 by performing both the function of cutting the wire 1 and the function of driving the wire 1 (pin 3) into the workpiece (bobbin 2). Thus, the reliability of the pinning device 10 can be improved and the cost of the pinning device 10 can be reduced.

At this time, the pin guide machine 70 is operated so that the pin guide block 71 is opposed to the pin 3 to perform the driving preparation step of surrounding the pin 3 with the guide cutter groove 34.

  Based on the above configuration, the pin guide block 71 guides the pin 3 to and from the guide cutter groove 34 in the driving step, so that the thin pin 3 is reliably driven without bending.

  In the present embodiment, after the cut backup machine 60 is operated and the cut backup block 61 is separated from the guide cutter 30 in the driving preparation step, the pin guide machine 70 is operated to bring the pin guide block 71 closer to the guide cutter 30. The configuration.

  Based on the above configuration, the push cutter 40 for driving the pin 3 is prevented from interfering with the backup block 61 in the driving preparation step. In the cutting process and the driving process, the thin wire 1 (pin 3) is bent by switching the position where the wire 1 that fits in the guide cutter groove 34 and becomes the pin 3 is surrounded by the backup block 61 or the pin guide block 71. The cut pins 3 are reliably driven without bending into the work (bobbin 2).

  Note that the cut backup block 61 and the cut backup machine 60 may be eliminated, and the pin guide machine 70 may be provided with a mechanism for moving the pin guide block 71 in the Z-axis direction. In this case, the pin guide block 71 is brought into contact with the guide cutter 30 at an upper position close to the push cutter 40 in the cutting preparation process and the cutting process, while the lower position away from the push cutter 40 in the pressing preparation process and the pressing process. So as to contact the guide cutter 30. In this way, in the cutting process and the driving process, the position where the wire 1 that fits in the guide cutter groove 34 and becomes the pin 3 is surrounded by the pin guide block 71 is switched, so that the thin wire 1 (pin 3) is surely not bent. And the pin 3 that has been cut is reliably driven without bending into the workpiece (bobbin 2).

  Further, the pin guide block 71 and the pin guide machine 70 may be eliminated, and the cut backup machine 60 may be provided with a mechanism for moving the cut backup block 61 in the Z-axis direction. In this case, the cut backup block 61 is brought into contact with the guide cutter 30 at the upper position close to the push cutter 40 in the cutting preparation process and the cutting process, while the lower position away from the push cutter 40 in the pressing preparation process and the pressing process. So as to contact the guide cutter 30. In this manner, in the cutting process and the driving process, the position where the wire 1 that fits in the guide cutter groove 34 and is surrounded by the cut backup block 61 is switched, so that the thin wire 1 (pin 3) is surely not bent. And the pin 3 that has been cut is reliably driven without bending into the workpiece (bobbin 2).
