Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a mounting device for a magnetic head core used for manufacturing a magnetic head having a pair of adjacent magnetic head cores, and particularly relates to a mounting device for a magnetic head core, which is used for manufacturing a magnetic head having a pair of adjacent magnetic head cores. The present invention relates to a magnetic head core mounting device that can greatly simplify the process.

[Prior Art] The magnetic head shown in FIGS. 8 and 9 is used in a video tape recorder, in which a protrusion 63 with a slit 62 formed in the center is formed on one side of a roughly square base plate 61. The magnetic head cores 64 and 64 are fixed to the tips of the protrusions, respectively. Such a magnetic head is attached to the tip of a rotating arm built into the drum of a video tape recorder through an insertion hole 65 in the center of the base plate 61, and sends and receives signals by scanning the magnetic tape wound around the drum. It is designed to do this.

In this type of magnetic head, two head cores 64
The reason for this is to make the image clearer during special playback. In such a magnetic head, if the levels of the tape sliding surfaces of the two head cores 64 do not match exactly, the two heads will not trace the same position on the tape, and the fidelity of the signals sent and received will decrease. Since this increases noise, it is necessary to precisely match the level of the sliding surfaces of both heads. To do this, conventionally, a jig is used to grip the first and second head cores 64 with their sliding surfaces aligned at the same level, and an adhesive resin is applied while the head cores 64 are gripped by this jig. , both head cores 64 were fixed simultaneously by pressing against the base plate 61.

[Problems to be Solved by the Invention] However, in the conventional techniques as described above, there was a problem to be solved in that the winding process was very time-consuming. That is, two head cores 64 are fixed to the base plate 61 in parallel, and furthermore, in order to miniaturize devices and improve recording density, the head cores 64 themselves have become smaller and their installation intervals have become narrower. . The work of winding a thin wire around the head core 64 having such a complicated and fine structure requires skill even when performed manually, and is inefficient. On the other hand, when winding work is mechanized, in a magnetic head in which one head core 64 is attached to the base plate 61, the base plate 61 is placed upright on a base that rotates in a horizontal plane, and the winding hole is A device has been proposed in which the wire is wound by rotating the base while gripping one end of the inserted wire (Japanese Patent Application No. 63-27).
No. 2116). In such a device, winding can be done quickly and stably by rotating the head instead of the wire, but it is not applicable to a magnetic head in which two head cores are already fixed, such as the subject of this application. It is difficult to do so because the wire and the other head interfere.

An object of the present application is to provide a head core mounting device that can simplify the winding work by applying the above-described winding machine to at least one of the magnetic head cores.

This configuration includes a positioning device that positions the device by slightly moving it relative to the device, and a fixing device that fixes the device in the positioned state.

[Function] In such a magnetic head core mounting device, after the first head core is mounted on the base plate by the first head core mounting device, the base plate is moved to a position facing the second head core mounting device by the conveyance device. , positioning the second head core while slightly moving it using the second head core mounting device, so that the deviation in the level of the sliding surface of the second head core with respect to the first head core is within a certain reference range. do.

Hereinafter, a process of attaching a head core using the magnetic head core attaching apparatus configured as described above will be explained.

First, the base plates 1 are sequentially fed from the base plate supply device 1a, and fixed to the carrier IO at the base plate attachment position of the transport device 2. That is, a mechanism for releasing the clamp 17 of the carrier 10 is provided at this base plate mounting position,
As a result, the base plate l at the tip of the robot arm 3a is held at the base plate holder 1 of the carrier 10 with the clamp I7 lifted.
6 and lower the clamp 17 to fix it. next,
The carrier 10 is transferred to a position facing the first head core mounting device 3, and the head core 1 is mounted by the first head core mounting device 3.
9 is supplied to the head core stand 20.

The head core 19 moves from the stock part 22a to the positioning part 22.
After being moved and positioned, it is supplied onto the head core stand 20 of the carrier 10 by the transfer section 23. The head core 19 is placed on the head core stand 20 and the suction hole 21
The head core 20 is fixed in place by the negative pressure of the head core 20.
As shown in FIG. 3, the heights of the base plate 1 and the base plate 1 are deviated in the vertical direction. Here, carrier IO lifting platform 1
5 is pushed down to press the base plate l against the head core 19, and the carrier 10 is further transferred to the resin application position by the conveyor 2, and here the resin P is applied to the joint between the base plate 1 and the head core 19.
supply. The resin P is not supplied between the surfaces of the base plate 1 and the head core 19, but is supplied to the intersection between the upper surface of the head core 19 and the lower end surface or side end of the base plate 1, as shown in FIG. Therefore, the resin layer hardly penetrates between the surfaces of the base plate l and the head core 19. Therefore, it is less likely that the head cores 19 will shift in the Z direction due to variations in the thickness of the resin layer. The base plate l coated with resin P in this way
Then, the head core 19 is further moved to the rib of the resin curing device 5, and is cured and fixed by exposing the resin P to ultraviolet rays, for example.

Next, the carrier IO is moved along the conveyance line to the front of the second head core attachment device 6, and here, the stock part 2
The second head core 19 is supplied from 2 a to the top of the head core stand 20 via the transfer section 23 and temporarily fixed by the negative pressure of the suction hole 21 . Here, although the position of the head core 19 is generally constant, the position of the head core 19 is
There is a slight deviation relative to 9. In this state, the carrier 10 is transferred to the old part of the resin coating device 8, and resin is coated in the same manner as the first head core. Next, the carrier IO is transferred by the transport device 2 and moved in front of the position adjustment device 7. In the position adjustment device 7, the button 42 attached to the lower end of the second slide member 41 is positioned slightly above the top surface of the head core stand 20 of the carrier 10, and the operator can use the screw 50 for moving in the X direction. and handles 50a and 5 of the neno 51 for moving in the Y direction.

Rotate 1a and 5 lb to connect the first head core 19a and the second head core! 9b so that their relative positions are aligned. At this time, the second head core 19b
is temporarily fixed on the head core stand 20 by being pressed by the base plate I, so that it can freely move relative to the head core stand 20 by pressing the two sides with the pusher 42. Note that when positioning the head core 19, the head core 19 cannot be moved in the direction of being pulled back by the bushings 42, but since the bushings 42 move at a very slow speed, there is no problem in actual positioning work. With the carrier 1 positioned in this way,
0 in front of the curing device and fix it.

Note that the above explanation omits the winding process, but the first
After the head core is attached, the first Δ and rad core is wound in an appropriate manner. That is, the base plate 1 itself or the carrier lO may be removed from the conveying device 2 and attached to a winding machine for winding, or the winding may be performed manually. When using a winding machine, as mentioned above, only i magnetic head cores are fixed, so it is necessary to use a device that winds the wire by rotating the base plate itself without interference between the wire and other head cores. Even when the head cores are installed manually, the work is much easier than when the two head cores are both attached.

[Effects of the Invention] As detailed above, the present invention includes a conveyance device that intermittently conveys a base plate, and a first head core attachment device and a second head core attachment device installed along the conveyance device. By providing the second head core mounting device with a positioning device that positions the second head core by slightly moving it relative to the base plate, and a fixing device that fixes the second head core in the positioned state, the two magnetic head cores can be fixed. Since the magnetic heads such as the one shown in FIG.

By incorporating a wire process, this winding process can be mechanized or easily performed by hand, which is an excellent effect.
