Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field> □ The present invention relates to a device for positioning a magnetic head □ on a gimbal for supporting a magnetic head of a magnetic disk device.
□ <Prior art> Double-sided flexible magnetic/magnetic disk drives can follow changes in the position of the magnetic disk caused by bending of the jacket, etc., and can achieve stable □ 7-degree contact between the magnetic disk and the magnetic disk. Thus, the magnetic head is fixed to an elastic gimbal having a multidirectional fulcrum.

The magnetic head is supported and mounted in a double-sided flexible magnetic disk device, as shown in FIG. The pivot projection 4 is configured to press the center position of the back surface. A magnetic disk 5 is sandwiched between opposing magnetic heads 1.1, and information is recorded and reproduced on the magnetic disk 5. In this magnetic disk device, if the fixed position of the magnetic head relative to the gimbal deviates from a predetermined position, the stable point changes due to the influence of the weight around the magnetic disk and the magnetic head, causing track deviation of the magnetic head. Therefore, high positioning accuracy is required for fixing the magnetic head to the gimbal. As shown in Figure 10, to the magnetic field 7
The fixing position accuracy of the hand 1 with respect to the gimbal 3 is, for example, ±0.0 in both the X direction and the Y direction. ．． It is 1m.

Conventionally, the work process of positioning and fixing the magnetic head to the gimbal for supporting the magnetic head was performed manually, but as mentioned above, high precision is required for positioning the magnetic head with respect to the gimbal. In addition to requiring a long time, the fixing position of the magnetic head relative to the gimbal lacks reproducibility, resulting in a problem of poor product yield.

The magnetic head is placed on the magnetic head supporting gimbal by the conveying means, and the magnetic head supporting gimbal is moved by the driving means to position the magnetic head on the magnetic helad supporting gimbal. It is characterized by what it did.

A predetermined biasing force is applied to the spring 38.

FIG. 4 shows the partial configuration of the suction part of the suction pad 13,
The four holes 40 are for attracting the magnetic head supporting gimbal 2, and the recess and head attracting hole 41 are for attracting the magnetic helad 1. The suction pad 13 has
Five sets of these four holes 40, depressions, and head suction holes 41 are formed in parallel.

Hereinafter, a procedure for positioning the magnetic head on the magnetic head supporting gimbal using the above-described apparatus will be explained.

The suction pad 13 moves in the direction of arrow A2 due to the drive of the cylinder 16.
direction, and picks up five magnetic head supporting gimbals 2 placed on the gimbal tray 23 at once. Then, by driving the cylinder 16, the suction pad 13 moves toward the arrow A.
After moving in one direction, the member 17 is driven by the transport motor 21 and the feed screw 22, and the suction pad 13 moves in the direction of arrow B2.
direction, and the five gimbals 2 are conveyed to above the positioning plate 30. When the suction pad 13 reaches a predetermined position on the positioning plate 30, the cylinder 16 is driven to
The suction pad 13 moves in the direction of arrow A2. As shown in FIG. 3, the positioning pins 32 and 33 protruding from the groove 31 of the positioning plate 30
1.12 and position the gimbals 2 with respect to the positioning plate 30, the suction force of the suction pad 13 is cut off, and the five gimbals 2 are placed at predetermined positions on the positioning plate 30. Thereafter, the suction pad 13 moves in the direction of the arrow A1 by the drive of the cylinder 16, and then moves in the direction of the arrow B1 by the driving force of the transport motor 21 and the feed screw 22 to the position where the suction pad 13 first attracted the gimbal 2. Moving.

Next, the gimbal tray 23 and head tray 24 move in the direction of arrow C1 by the driving force of the transport motor 28 and the feed screw 29, and the head tray 24 moves to the position where the gimbal tray 23 was previously. Then, the suction band 13 is driven by the cylinder 16 and moves in the direction of arrow A2, attracts five magnetic heads 1 on the head tray 24 at once, moves in the direction of arrow A1, and then moves to the direction of arrow A1. Due to the driving force of the feed screw 22, the suction pad 13 moves in the direction of arrow B.
The five magnetic heads 1 move in two directions, and the five magnetic heads 1 touch the positioning plate 30.
It is transported to the top. The suction pad 13 is the positioning plate 30
When the suction pad 13 reaches the predetermined position above the
Moving in two directions, the magnetic head core la of the magnetic head 1 is inserted into the opening 10 of the gimbal 2 placed on the positioning plate 30, as shown in FIG. Then, the suction force of the suction pad 13 is cut off, and the five magnetic heads 1 are respectively placed on the five gimbals 2 at the same time. At this time,
The magnetic head core 1a passes through the aperture lO of the gimbal 2,
The penetrating portion 1b of the magnetic head core 1a enters into the groove 31 of the positioning plate 30. FIGS. 5 and 6 respectively show the planar and cross-sectional configurations of the magnetic head 1 and gimbal 2 in this state. After placing the magnetic head 1 on the gimbal 2, the suction pad 13 moves in the direction of arrow A1.

When positioning the gimbal 2 on the positioning plate 30 using the positioning pins 32 and 33 and when inserting the magnetic head core la of the magnetic head 1 into the opening 10 of the gimbal 2, the pin fixing plate 34 resists the bias of the spring 38. It is pressed against the stopper 37 by the bias of the cylinder 36, and is positioned at a predetermined position.

Then, when the gimbal 2 and magnetic helad 1 are completely placed on the positioning plate 30 by the above-described operation, the cylinder 3
6 is removed, and with the bias of the spring 38, the pin fixing plate 34 is guided by the linear guide 35° 35 and moves in the direction of arrow B2, and the positioning pin 32.6 fixed to the pin fixing plate 34 is moved. 33 moves in the direction of arrow B2. By moving the positioning bins 32 and 33 in the direction of arrow B2, the gimbal 2 moves in the direction of arrow B2, as shown in FIG.
The penetrating portion 1b of the magnetic/head core 1a is the wall 3 of the groove 31.
1a, the magnetic head core 1a is prevented from moving in the direction of arrow B2 by the wall 31a.

Then, as the gimbal 2 further moves in the direction of arrow B2, the magnetic head core 1a moves into the opening 10 of the gimbal 2.
The magnetic head 1 is guided by the hypotenuse 10c or 10d and fits into the 4th part surrounded by the side 10a and the hypotenuses 10c and 10d, completing the positioning of the magnetic head 1 with respect to the gimbal 2 in the X and Y directions. 7 and 8 respectively show the planar configuration and cross-sectional configuration of the magnetic head 41 and the gimbal 2 in a state where positioning has been completed. In this way, the magnetic head core 1a is connected to the aperture 1 of the gimbal 2.
By simply moving the gimbal 2 in one direction while being guided by the oblique side 10c or 10d of the magnetic head 1, the magnetic head 1 can be positioned with respect to the gimbal 2 in the X and Y directions. When the positioning of the magnetic head 1 is completed, the magnetic head 1 is then bonded to the gimbal 2 with instant adhesive using an automatic adhesive dropping device (not shown).

Through the above series of operations, it becomes possible to position and bond five magnetic heads to five gimbals at once.

<Effects of the Invention> As explained above, in the present invention, the positioning of the magnetic head with respect to the gimbal for supporting the magnetic head can be performed automatically, thereby reducing the time required for manufacturing the magnetic head supporting device. Mass production becomes possible and cost reduction can be achieved. Furthermore, by forming the opening into which the magnetic head core of the magnetic head supporting gimbal is inserted into a specific shape, the positioning process can be simplified and the positioning device can be simplified.
