Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spacer insertion bonding apparatus for a magnetic core.
[0002]
[Prior art]
The toroidal coil is formed by winding a thin strip made of amorphous metal with excellent magnetic properties in an annular shape, forming a C-shape by forming a slit in a part of the strip, and then using a spacer in the slit to maintain the slit spacing There is something that intervenes.
[0003]
When attaching a spacer to the slit of the C-shaped toroidal coil, conventionally, the spacer is leveled and an adhesive is applied to the upper and lower surfaces thereof, and this spacer is inserted into the slit of the toroidal coil to cut off the excess portion. The way was done. In addition, a method of applying an adhesive around the spacer after inserting the slit into the slit and cutting an excess portion before applying the adhesive to the spacer has been performed.
[0004]
[Problems to be solved by the invention]
However, in the conventional method of applying the adhesive to the spacer and then inserting it into the slit, the adhesive is applied upward from the nozzle disposed on the lower side of the spacer in order to apply the adhesive to the lower surface side of the horizontal spacer. Since the discharged adhesive is discharged, there is a problem that a “liquid dripping” phenomenon occurs in which the discharged adhesive hangs down by its own weight.
[0005]
When this dripping occurs, not only the adhesive cannot be accurately applied to the spacer, but also in some cases, the adhesive adheres to the nozzle hole and the nozzle hole is blocked, or other parts around the nozzle are blocked. There was a risk that the adhesive would adhere and cause dirt and malfunction.
[0006]
In addition, when the spacer is inserted into the slit, the adhesive applied to the spacer is scraped off at the edge of the slit, and a necessary amount of adhesive cannot be secured, resulting in a decrease in the adhesive strength of the spacer. .
[0007]
On the other hand, the method of inserting the adhesive into the slit before applying the adhesive to the spacer and then applying the adhesive around the spacer has a problem that the adhesive strength of the spacer is weakened.
[0008]
An object of the present invention is to solve such problems and prevent the occurrence of dripping phenomenon of the adhesive and prevent the adhesive applied to the spacer from being scraped off at the edge of the slit. Accordingly, it is an object of the present invention to provide a spacer insertion / bonding device for a magnetic core capable of securing a necessary amount of an adhesive applied to the spacer and thereby reliably bonding the spacer to the magnetic core.
[0009]
[Means for Solving the Problems]
The present invention is a spacer insertion bonding apparatus for a magnetic core, and is configured as follows in order to solve the above-described technical problems. That is, the present invention is a spacer insertion bonding apparatus for a magnetic core that inserts and adheres a spacer to a slit of a C-shaped magnetic core, and holds the magnetic core and widens the slit. And a slit positioning means for rotating the slit widening means and receiving a stop signal to stop the rotation, thereby positioning the slit of the magnetic core at the spacer insertion position, and the slit positioning means being rotated by the slit positioning means Slit detection means for detecting the slit of the magnetic core and supplying the stop signal to the slit positioning means, turning the spacer 90 ° to arrange the adhesive application surface of the spacer vertically or horizontally, and Hold for a predetermined time when the adhesive application surface is vertical, and move the spacer when the adhesive application surface is horizontal Spacer turning insertion means for inserting into the slit at the spacer insertion position, adhesive application means for applying an adhesive to the adhesive application surface held vertically by the spacer turning insertion means, and the slit And a spacer cutting means for cutting the spacer inserted in a predetermined position.
[0010]
In this magnetic core spacer insertion / adhesion apparatus, since the spacer coated with the adhesive is inserted after widening the slit, it is possible to prevent the adhesive from being scraped off at the edge of the slit. In addition, since the adhesive is applied after the adhesive application surface is vertical, it is possible to prevent the adhesive from falling off the spacer.
[0011]
The adhesive application means may be provided with a nozzle for applying the adhesive, and the nozzle may discharge the adhesive obliquely downward.
In this case, the adhesive discharged from the nozzle can be prevented from dripping and the nozzle hole being blocked.
[0012]
Further, by relatively moving the nozzle and the spacer, the adhesive discharged from the nozzle can be intermittently applied to a plurality of positions on the adhesive application surface.
[0013]
In this case, since the amount of adhesive per location can be reduced, it is possible to prevent dripping even when a low viscosity adhesive is used.
Further, the slit widening means can expand the entire width of the inner peripheral surface of the magnetic core to increase the width of the slit.
[0014]
In this case, since a local force can be prevented from being applied to the magnetic core, deformation of the magnetic core and deterioration of the magnetic characteristics can be prevented.
[0015]

The spacer feeding unit 45 includes a pedestal 47 attached to the turning drive unit 46 and a plurality of rotating rollers 48 and 49 attached to the pedestal 47 in two rows.
[0029]
The spacer 4 is sandwiched between the rotating rollers 48 and 49 on both sides so as not to drop off, and the rotating rollers 48 and 49 are rotated by a predetermined angle in directions opposite to each other, whereby the spacer 4 is horizontally moved by a predetermined distance.

Further, the holding parts 62 and 63 convey the magnetic core 2 to the discharge position by the rotation of the holding plate 61, where the magnetic core 2 is opened and discharged to the collection box 64.
[0033]
Next, the operation of the spacer insertion bonding apparatus 1 will be described. In this spacer insertion bonding apparatus 1, first, as shown in FIG. 3, the magnetic core 2 aligned with the core feed portion 21 of the core supply means 11 descends in the core feed portion 21 by its own weight, for example, and waits. It is dropped onto the core receiving part 27 of the core conveying part 22 at the position. At this time, the opening on the slit widening means 12 side of the core receiving portion 27 is closed by the shutter 24.
[0034]
Next, as shown in FIG. 7, the shutter 24 is raised to open the opening on the slit widening means 12 side of the core receiving portion 27. Subsequently, as shown in FIG. 8, the cylinder 23 is operated to move the core conveyance unit 22 horizontally toward the core widening unit 12 side. The magnetic core 2 placed on the core receiving portion 27 is fitted into the chuck portion 34 of the collet chuck 30 (FIG. 4) of the core widening portion 12. Thereafter, the chuck portion 34 is enlarged and the magnetic core 2 is held.
[0035]
When the core transport part 22 is moving horizontally, the magnetic core 2 at the lowermost end in the core feed part 21 is stopped by a stopper (not shown) so that it does not fall inadvertently. After the magnetic core 2 is held by the chuck portion 34 of the slit widening portion 12, as shown in FIG. 9, the core transport portion 22 is moved horizontally and returned to the standby position, and then the shutter 24 is lowered. Then, the stopper of the core feed part 21 is opened, and the internal magnetic core 2 is dropped onto the core receiving part 27 of the core transport part 22.
[0036]
Thereafter, as shown in FIG. 10, the horizontal driving means 40 of the slit detecting means 14 is operated, and the support plate 41 attached thereto is horizontally moved to the core widening portion 12 side. As a result, the photo sensor 42 on the support plate 41 approaches the magnetic core 2 held by the chuck portion 34 of the core widening portion 12 to a predetermined distance. Next, the core widening portion 12 is rotated at a high speed, for example, in the counterclockwise direction by the slit positioning means 13.
[0037]
Thus, by rotating the core widening part 12, the magnetic body core 2 currently hold | maintained is rotated. While the magnetic core 2 is rotating, detection light is irradiated from the photo sensor 42 of the slit detection means 14 toward the outer peripheral surface of the magnetic core 2, and the detection light reflected by the magnetic core 2 is photo Light is received by the sensor 42. The presence or absence of the slit 3 can be detected by measuring the intensity of the detection light.
[0038]
When the photosensor 42 detects the slit 3 of the magnetic core 2, a stop signal is sent from the photosensor 42 and supplied to the slit positioning means 13. In response to this stop signal, the slit positioning means 13 stops. Next, as shown in FIG. 11, the slit positioning means 13 is rotated at a relatively low speed in the opposite direction to the previous time, that is, in the clockwise direction. When the slit 3 is detected by the photo sensor 42, a stop signal is sent and the slit positioning means 13 stops. As a result, the slit 3 is arranged at a predetermined position, that is, at the spacer insertion position.
[0039]
As described above, when the slit 3 is positioned, the rotation direction and the rotation speed of the magnetic core 2 are changed by first detecting the slit 3 as fast as possible by rotating it in the counterclockwise direction at a high speed. This is because the slit 3 is accurately arranged at a predetermined position by rotating the magnetic core 2 overrun by inertia at a low speed in the reverse direction when the rotation is suddenly stopped.
[0040]
At the same time as positioning the slit 3 in this way, or before or after that, as shown in the figure, the spacer feeding portion 45 is turned 90 ° by the turning drive portion 46 of the core turning insertion means 15, and the pedestal 47 is moved. Placed horizontally. As a result, the rotating rollers 48 and 49 on the pedestal 47 are set up vertically, and the spacers 4 sandwiched therebetween, and thus the adhesive application surfaces 5 and 6 are arranged vertically. Retained.
[0041]
After the spacer 4 is vertically set up by the spacer turning insertion means 15, the support plates 53 and 54 of the adhesive application means 16 are horizontally moved in the direction approaching each other as shown in FIG. Then, as shown by a two-dot chain line in FIG. 6, the nozzles 51, 52 attached to the support plates 53, 54 approach the adhesive application surfaces 5, 6 of the spacer 4 to a predetermined distance and obliquely move from the nozzles 51, 52. A predetermined amount of the adhesive 55 is intermittently discharged downward and applied to the adhesive application surfaces 5 and 6.
[0042]
At the time of application of the adhesive, the nozzles 51 and 52 move in the first direction along the adhesive application surfaces 5 and 6 as described above, in this example, the vertical direction, and the spacer 4 is bonded by the rotary rollers 48 and 49. It is moved in a second direction that is parallel to the application surfaces 5 and 6 and perpendicular to the first direction, in this example, in the horizontal direction. Then, the moving direction of the nozzles 51 and 52 and the moving direction of the spacer 4 are appropriately combined, and the adhesive 55 is provided at a plurality of positions at appropriate intervals between the adhesive application surfaces 5 and 6 as shown in FIG. It is applied in the form of dots. In this example, the adhesive 55 is applied to a total of six places, three places vertically and two places horizontally.
[0043]
After the adhesive 55 is applied to the adhesive application surfaces 5 and 6 of the spacer 4 in this way, the photosensor 42 of the slit detecting means 14 is returned to the original standby position as shown in FIG. The spacer feeding portion 45 of the inserting means 15 is turned 90 ° to return the spacer 4 to the horizontal state. Further, the support plates 53 and 54 of the adhesive application means 16 are horizontally moved away from each other, and the nozzles 51 and 52 are returned to the original standby positions.
[0044]
Next, as shown in FIG. 15, the slit positioning means 13 is lowered by a predetermined distance, and the slit 3 of the magnetic core 2 held by the slit widening means 12 is held by the spacer turning insertion means 15. 4 is arranged just beside the tip. Subsequently, as shown in FIG. 16, the rotation rollers 48 and 49 of the spacer swivel insertion means 15 are rotated, whereby the spacer 4 is horizontally moved to the slit 3 of the magnetic core 2 by a predetermined length, in this example. It is inserted until it hits the chuck portion 34.
[0045]
Next, the holding plate 61 of the core discharging means 18 is horizontally moved to the spacer turning insertion means 15 side by the driving means 60, and the magnetic core 2 is held from above and below by one holding portion 62 attached to the holding plate 61. The Thereafter, the actuator 31 (FIG. 4) of the slit widening portion 12 is operated, and the rod 36 is pulled out from the taper 35 of the chuck portion 34. As a result, the diameter of the chuck portion 34 is reduced, and the magnetic core 2 can be extracted from the chuck portion 34.
[0046]
Subsequently, the clamping pressure of the clamping unit 62 is further increased, and the magnetic core 2 is pressed with a predetermined pressure. Thus, both end surfaces of the slit 3 of the magnetic core 2 are pressed against the spacer 4 with a predetermined force, and the magnetic core 2 and the spacer 4 are securely bonded. Thereafter, as shown in FIG. 17, the spacer cutting means 17 is raised while rotating, and the spacer 4 is cut from a predetermined position. In this example, the spacer 4 is cut along the outer peripheral surface of the magnetic core 2.
[0047]
After the spacer 4 is cut, as shown in FIG. 18, the holding plate 61 of the core discharging portion 18 is moved horizontally and returned to the original standby position. Thereafter, the holding plate 61 is rotated 180 °. Thereby, as shown in FIG. 19, the holding parts 62 and 63 on both sides of the holding plate 61 are replaced, and the magnetic core 2 held by the holding part 62 is arranged at the discharge position.
[0048]
And the clamping pressure of the clamping part 62 falls, the magnetic body core 2 is open | released, and it discharges | emits to the collection box 64. FIG. At this time, the quality of the magnetic core 2 can be judged by appropriate quality judgment means (not shown), and the good product and the defective product can be distinguished and discharged.
[0049]
Simultaneously with the recovery operation of the magnetic core 2, the slit positioning means 13 is raised and returned to the standby position. As a result, the entire spacer insertion bonding apparatus 1 returns to the initial position, and thereafter, the bonding process of the spacer 4 is repeatedly performed as described above.
[0050]
As described above, the spacer insertion bonding apparatus 1 widens the slit 3 of the magnetic core 2 by the widening means 12 and then inserts the spacer 4 coated with the adhesive 55 into the slit 3. It is possible to prevent the adhesive from being scraped off at the edge. Therefore, the necessary amount of the adhesive 55 applied to the spacer 4 can be secured and the spacer 4 can be securely bonded to the magnetic core 2. Moreover, since the spacer 4 thicker than the set width of the slit 3 can be inserted, the processing accuracy of the slit 3 and the spacer 4 can be lowered to facilitate the processing.
[0051]
Further, since the adhesive 55 is discharged obliquely downward from the nozzles 51 and 52 (FIG. 6) of the bonding means 16, the adhesive 55 drips and the nozzle holes are closed, or the nozzles 51 and 52 It is possible to prevent the peripheral portion from being contaminated with an adhesive and causing malfunction.
[0052]
Furthermore, since the adhesive 55 discharged from the nozzles 51 and 52 is intermittently applied to a plurality of positions on the adhesive application surfaces 5 and 6 of the spacer 4 arranged vertically, the adhesive applied to one place. The amount of 55 can be reduced. Therefore, even if the low-viscosity adhesive 55 is used, the occurrence of dripping can be prevented, so that the configuration of the adhesive application means 16 can be simplified.
[0053]
【The invention's effect】
As described above, according to the spacer insertion bonding apparatus for magnetic cores of the present invention, since the spacer coated with the adhesive is inserted after widening the slit, the adhesive is scraped off at the edge of the slit. As a result, a necessary amount of adhesive can be secured and the spacer can be securely bonded to the magnetic core. Also, since the adhesive is applied after the adhesive application surface is vertical, it is possible to prevent the adhesive from falling off the spacer, so that each part under the spacer is soiled with adhesive and operates It is possible to prevent the occurrence of defects.
[0054]
In addition, when a nozzle for applying adhesive is provided on the adhesive application means and the adhesive is discharged obliquely downward from this nozzle, the adhesive discharged from the nozzle drips and the nozzle hole is blocked. Can be prevented.
[0055]
Furthermore, when the adhesive discharged from the nozzle is intermittently applied to a plurality of positions on the adhesive application surface by relatively moving the nozzle and the spacer, the amount of adhesive per location is reduced. Therefore, dripping can be prevented even when a low viscosity adhesive is used. Therefore, the structure of the adhesive application means can be simplified by using a low-viscosity adhesive that is easy to handle.
[0056]
In addition, if the slit width is increased by expanding the inner peripheral surface of the magnetic core as a whole by the slit widening means, it is possible to prevent local force from being applied to the magnetic core. Deformation of the body core and deterioration of the magnetic properties can be prevented.
