Example of Invention

Next, an embodiment in which the method of the present invention is applied to a magnetic head for perpendicular magnetization will be described with reference to the drawings.

That is, as shown in FIG. 1A, the core hole (3) of the first magnetic head is set by the first insertion mechanism (first wire insertion means) (2) for positioning and setting the tip of the wire (1). ) Center position "X", and the first suction nozzle (first suction means) (4) is set on the opposite side, and then the roller (L) sucks the wire in the conveyed state, Pass the tip of 1) through the core hole (3) as shown in a. The chip (5) is rotated as shown in the drawing so that it is wound around the chip (5) while passing through the wire (1). The axis of rotation at this time is the straight line A shown in FIG.

Next, the tip of the wire (1) is guided to the center of the core hole (3) by the second insertion mechanism (second wire insertion means) (6) provided on the opposite side and provided on the other side. The second suction nozzle (second suction means) (7) is also guided to the central portion of the core hole (3), and the roller (L) sucks the wire in the transporting state so that the wire tip as shown in FIG. The return to the core hole (3) is completed and the winding for one turn is completed. By repeating this process with a single wire a desired number of times, it is possible to wind around the outer core portion (8) of the chip (5) as shown in FIG.

That is, the winding of the coil (9) of the magnetic head for erasing the perpendicular magnetization is formed.

The first insertion mechanism (2) and the second insertion mechanism (6)
For example, the structure of Japanese Patent Laid-Open No. 60-9161 is cited as the prior art.
Similarly to the pair of blocks (31) of the first and second wire feeding devices (18) and (20) disclosed in Japanese Patent Publication No. 4 (1998), a pair of gripping bodies having an openable / closable (separable) structure. It can be configured.

Next, the winding of the coil of the perpendicular magnetic recording magnetic head will be described with reference to FIG.

The tip of the wire (11) is set to the guide position by the first insertion mechanism (2) at the center of the core hole of the tip (10), and the first suction nozzle (4) is moved to the opposite side to set the suction position. In operation, the wire (11) is sucked and passes through the core hole (14). At this time, the wire (11) used has a structure in which two wires are insulated from each other and integrated in parallel. The two-wire wire can be wound without twisting.

Therefore, the sucked wire (11) rotates in the winding direction of the tip (10) as shown in the drawing while being stretched by the suction or stretched by gripping. The rotation axis at this time is the second
It is a straight line B shown in the figure. Then, the tip of the wire (11) is guided by the second insertion mechanism (6) to the central position of the coil hole (14) of the tip (10) to set the position and move the suction nozzle (7) to the position. By setting, one-turn winding with two main wires is completed. If a desired number of this step is carried out, the coil (15) of the magnetic head for magnetic recording / reproducing for perpendicular magnetization is wound by winding on the 35th floor.

The structure of this magnetic head is shown in FIG.

That is, the winding on the chip (5) configured to form the head gap (33) by the core pieces (31) (32) made of a ferromagnetic material and the head gap (36) by the core pieces (34) (35) It shows the winding on the chip (10) configured to be formed.

FIG. 3 shows the above description more specifically in the order of steps.

FIG. 3 (A) shows a winding process of the erasing magnetic head, and FIG. 3 (B) shows a winding process of the recording / reproducing magnetic head.

After setting the magnetic head which is the work, the wire (1) is guided from the wire winding frame (not shown) to the wire insertion mechanism (2) through the guide roller (41), and this mechanism (2) is moved to the tip ( When the tip of the wire (1) is controlled so as to be located at the X position of the core hole (3) of 5) and the suction nozzle (4) is set to the opposite X position and suction is performed, the wire (1) is as shown in the figure.
Penetrates.

Next, in order to hook the winding start end of the wire (1) on the L-shaped grip (42) as shown in the figure, the tip (5) is rotated 90 degrees in the direction opposite to the wire winding direction. By this rotation, the wire (1) is pressed, and then the cutter (43) provided in the wire insertion mechanism (2) is lowered to perform wire cutting.

Next, in the direction in which the wire (1) is wound around the chip (5)
Rotate it by 270 degrees and wind the passed wire (1) around the outer core (8) as shown in FIG. The rotation of 270 degrees was 90 degrees in the opposite direction in the step b, so it is 180 degrees if there is no rotation operation in the step b.

Next, the tip of the wound wire (1) is guided to the core hole by the second insertion mechanism (6), the suction nozzle (7) is installed in the passage hole path of this core hole, and suction operation is performed as shown in FIG. .

By this suction, the wire (1) passes through the core hole (8) and one turn is completed.

Next, the tip (5) is rotated 180 degrees so as to be wound around the outer core (8) as shown in FIG.

Next, as in the case of (a), the insertion mechanism (2) guides to the X position of the core hole (3) to set the position and the suction nozzle (4)
The wire (1) is passed through the core hole as shown in FIG.

Then, the tip (5) is rotated 180 degrees as shown in the figure to wind the outer core (8) for three turns.

A state in which such a process is repeated 30 turns is as shown in FIG.

Next, after the winding is completed, the tip is rotated 90 degrees, and the cutter (43) provided on the insertion mechanism (2) hooked on the lock mechanism of the wire (1) cuts the terminal end of the wire (1). Then, the winding process of the chip (5) is completed.

Next, the wire (11) of the two wires is wound by the process shown in Fig. 3 (B). Since this step is the same as the step shown in FIG.

In this way, the head coil of the magnetic head for perpendicular magnetization can be automatically wound. Although the winding of the magnetic head for perpendicular magnetization has been described in the above embodiment, any composite magnetic head can be applied.
