Description

TECHNICAL FIELD The present invention relates to a wire rod adhesive application device used when winding a wire rod while applying an adhesive agent to manufacture a winding wire.

Conventional technology When winding wires to manufacture windings, the WET winding method, which uses an adhesive such as epoxy to bond the wires, is the DRY winding method, which uses bond wires to bond the wires. The winding machine is relatively less expensive than the winding machine, but the operator is very particular about the winding machine. Therefore, it is necessary to increase the productivity of windings per operating time of the winding machine. However, the conventional method of applying the adhesive between the layers of the winding by brushing is time consuming and does not increase the productivity of the winding.

Therefore, a method has been partially adopted in which the felt is soaked with the adhesive and the wire is passed through the felt before the winding machine to continuously apply the adhesive to the wire.

However, in this method, the amount of adhesive applied to the wire increases when the adhesive is supplied to the felt, and the amount of adhesive applied to the wire gradually decreases by the time the next adhesive is supplied to the felt. As described above, the amount of adhesive applied to the wire varies, and it is difficult to stably and continuously apply a fixed amount of adhesive to the wire.

Also, since the adhesive application process is the final process of winding manufacturing,
With the felt, it is difficult to make the position of the wire in the height direction (the position where the wire is introduced) in front of the winding machine constant. If a sheave is installed on the downstream side of the felt, the position of the wire in the height direction can be made constant in front of the winding machine, but this is impossible because the sheave becomes sticky with an adhesive.

Furthermore, when winding a wire around a square coil, the wire swings up and down due to fluctuations in the upper end position of the winding jig, but the felt cannot handle the runout, and it is difficult to perform line winding due to misalignment of the wire. is there.

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to make it possible to apply a fixed amount of adhesive to a wire continuously in a stable manner, and to keep the position of the wire in the height direction in front of the winding machine constant. Another object of the present invention is to provide a wire rod adhesive coating device that can wind the wire rods in a square coil in a lined manner without positional displacement of the wire rods.

Means for Solving the Problems The above-mentioned object is achieved by the wire adhesive application device according to the present invention. In summary, the present invention discloses that an adhesive winding ring for winding up the adhesive is rotatably disposed by immersing the lower part in the adhesive in a container accommodating the adhesive. On the outer peripheral surface of the upper part of the ring, the wire that is guided to the winding jig of the winding machine is suspended, and the adhesive application ring for applying the adhesive wound up by the adhesive winding ring to the wire is rotatable. Is disposed at the suspension position of the wire on the outer peripheral surface of the upper portion of the adhesive coating ring,
A wire rod adhesive coating device in which a wire rod holding ring for pressing the wire rod from above and preventing the wire rod from falling off the adhesive ring is rotatably provided. A groove for accommodating the wire rod is provided on the surface, and the outer peripheral surface of the adhesive winding ring is made of rubber and is configured to be inserted into the groove of the outer peripheral surface of the adhesive coating ring.
