Detailed Description of the Invention

[0001]

The present invention relates, in assembly and fabrication process of the core, to a rapid contact wearing location for bonding fixed by an adhesive sandwich the core of the halved left and right directions.

[0002]

2. Description of the Related Art Conventionally, a split core is adhered with a water-soluble adhesive, and the paste portion is forcibly dried in order to shorten the waiting time for the paste to dry naturally. When using a microwave oven as a drying oven, in order to prevent the water-soluble adhesive from swelling due to microwave irradiation and creating a gap in the adhesive surface of the core, before the core is dried The band is tightened or a microwave oven is provided with a clamp mechanism to clamp the core.

[0003]

According to the above-mentioned conventional rapid bonding method and its apparatus, the worker is required to attach and remove the band, and the band must be recovered, which requires a long working time. There was a problem of passing. When a microwave oven has a clamp mechanism, the clamp inside the furnace must be replaced every time the core type or size changes.
There is a problem that it is not suitable for high-mix low-volume production. Further, when a metal is used for the clamp part, there is a problem that electric discharge is generated by the microwave. Further, bearings and the like cannot be used because the internal grease is exhausted by the irradiation of microwaves, so that there is a problem that the mechanical mechanism is difficult to use.

[0004] The present invention is to provide a quick contact wearing location of the core to be clamped prior Iriro to microwave oven, may prevent discharge in the furnace together with the core can be automatically bonded in a short time The purpose is.

[0005]

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, will be described with reference to FIG rapid contact wearing location of the core in the embodiment of the present invention.

As shown in FIGS. 1 to 4, the core rapid bonding apparatus 1 comprises a microwave oven (not shown) and a carrier jig 2, and the carrier jig 2 clamps the core 3. The flat plate-shaped adherend mounting base 4 on which the core 3 is mounted, the pair of left and right clamp claws 5a and 5b for clamping the core 3 on the adherend mounting base 4, and the left and right The clamp claw drive mechanism 6 drives the clamp claws 5a and 5b to open and close.

The adherend mounting base 4 has a pair of channel-shaped members 7 and 8 arranged in parallel with each other in the longitudinal direction on the lower surface side of the mounting base and both ends of the channel-shaped members 7 and 8 facing each other. It has support members 9, 10, and 11 that connect between the parts and between the central parts. The adherend mounting table 4 is
A plurality of elongated hole-shaped cutout grooves 4a are formed in the left-right direction, and the clamp claws 5a and 5b pass through the cutout grooves 4a and project to the upper side of the adherend mounting base 4 to open and close along the cutout grooves 4a. Configured to work.

The clamp claw driving mechanism 6 has a pair of rod-shaped members 12 and 13 arranged along the longitudinal direction, and the rod-shaped members 12 and 13 are penetrated by and supported by the support members 9, 10 and 11, respectively. ing. The support member 10 is attached to each of the rod-shaped members 12 and 13.
Bearing metal 14, 15, 1 on each side
6 and 17 are slidably arranged. Each rod-shaped member 12,
A screw shaft 18 arranged parallel to the rod-shaped members 12, 13 is provided between the screw shafts 13, and the screw shaft 18 is provided for each of the support members 9, 1
It pierces 0 and 11 and is rotatably supported. Screw shaft 1
8 is divided into a right-hand threaded portion 18a and a left-handed threaded portion 18b with the support member 10 as a boundary. The right-handed threaded portion 18a is provided with a ball nut 19, and the left-handed threaded portion 18b is provided with a ball nut 2.
0 is slidably arranged by the rotation of the screw shaft 18. The screw shaft 18 is configured to be rotatable and driven by a torque motor (not shown) connected to the right screw portion 18a. The bearing metals 14 and 16 and the ball nut 19 are connected to each other by a connecting member 21 so that they slide integrally. The bearing metals 15 and 17 and the ball nut 20 are connected to each other by a connecting member 22 so that they can slide integrally. Both clamp claws 5a and 5b are connected to the connecting members 21 and 22, respectively. The lock nut 23, which is screwed into the end portion of the right-hand thread 18a, locks the ball nut 19 at a predetermined position, and is pressed (rotated and slid) to the ball nut 19 side by a cylinder device (not shown). ) And is configured to lock.

The adhesive for adhering the split core 3 to each other is a water-soluble adhesive, and the composition and proportion of the solvent and the viscosity are as follows. _{SiO 2 = 33.5% MgO = 2.1} % FeO = 0.1% Al 2 O 3 = 0.4% Na 2 O = 8.5% Mizukai Other = 55.4% Viscosity: about 20000 cp lock The nut 23, the screw shaft 18, the support members 9, 10,
A reinforced fluororesin is used for the contact portion with 11 in order to prevent discharge due to the antenna effect.

The operation of the above-described embodiment will be described below. In the object mounting base 4, the water-soluble adhesive is applied to the bonding surface of the core 3, and the core is mounted at a predetermined position on the mounting table 4 with the bonding surfaces aligned with each other.

In the clamp pawl drive mechanism 6, the ball nut 19 is rotated by rotating the torque motor.
(20) The bearing metal 14, 16 (15, 17) is integrally formed from the end side (shown in phantom line in FIG. 1) of the right-hand threaded portion 18a (left-hand threaded portion 18b) to the center side (in FIG. 1). Slide (shown by the solid line). Along with the rotational drive of the torque motor, the cylinder device presses the lock nut 23 toward the ball nut 19 side. When the lock nut 23 comes into contact with the ball nut 19 at the stop position, all the ball nuts 1
9, 20, the bearing metals 14, 15, 16, 17 are locked.

The clamp claws 5a and 5b are the ball nut 1
As the 9 (20) and the bearing metal 14, 16 (15, 17) slide toward the center side, the core 3 is clamped by closing along the notch groove 4a. As described above, by adopting the lock nut 23 and the torque motor, it is possible to maintain the state in which the core is clamped with an appropriate force so that the core is not broken and a gap is not formed on the bonding surface.

In the microwave furnace, the core 3
Irradiate with microwave to rapidly dry the adhesive. Thus, while the core 3 is held on the transfer jig 2 in a clamped state, the core 3 is transferred into the microwave oven using the conveyor device, and the adhesive is rapidly dried in the oven.
The core can be automatically bonded in a short time.

Further, since the reinforced fluororesin is used in the contact portion between the lock nut 23, the screw shaft 18 and the supporting members 9, 10, 11 and the absorption rate of microwaves is lowered, It is possible to prevent electric discharge in the microwave furnace.

[0020]

According to rapidly contact worn location of the core of the present invention, because it can automatically bonded in a short time a core, can reduce the burden on the operator, performs the shorter time compared to manual operations be able to. Further, since the transfer jig is provided outside the microwave oven, the clamp claws can be easily replaced, and thus workability can be improved and high-mix low-volume production can be supported.

Further, since a resin material capable of preventing electric discharge in the microwave furnace is used for the rotary contact portion between the lock nut and the screw shaft, the adhesive can be dried stably. As a result, high quality cores can be produced.
