The present invention relates to an insulator paper conveying and cutting device for an electric motor, and more particularly, to a conveying and cutting device for an electric motor that can be cut automatically by a certain length by conveying the insulation paper bent in the insulating paper automatic bending device.

In general, electric motors have a permanent magnet as a stator and an armature as a rotor, and an armature as a stator and a permanent magnet as a rotor. In the latter case, a coil is wound around the stator, which is the armature. When the current flows through the coil, the rotor is rotated by generating torque to the rotor together with the magnetic field of the permanent magnet, thereby generating the rotational force of the motor.

In this type of motor, the coil is inserted into the slot of the stator by using an angular copper or a copper wire, and a means of fixing the coil of the stator so that it does not protrude while being inserted into the slot is required. It is used to prevent coil protrusion. In other words, by inserting the coil into the slot of the stator and then inserting the insulating sheet bent in the U-shape into the slot, it also serves as insulation to prevent the coil from protruding.

In order to insert the insulating film for preventing the protruding coils into the slot of the stator, the width and length of the slot of the stator must be measured to cut and bend the insulating paper according to these specifications. Conventionally, all of these operations are performed manually by using a bending tool. Was done.

Since the work such as cutting of the insulating paper is all made by hand, there is a problem that it takes a lot of work time required for this, not only low production efficiency, but also difficult to produce a uniform product.

An object of the present invention is to provide an insulating paper conveying and cutting device capable of automatically cutting the insulating paper bent in a predetermined required length by automatic insulating paper bending device.

The present invention for achieving the object as described above is composed of a cutting device for fixing the insulating paper and a fixing device for fixing the insulating paper to easily cut the insulating paper and a cutting device for cutting the insulating paper.

The conveying apparatus has an insulating paper fixing cylinder installed vertically on the upper part so that the insulating paper can be fixed by pneumatic pressure, and a lower portion of the conveying cylinder is installed horizontally to move the insulating paper to the cutting device while moving forward and backward by the pneumatic pressure. It is structured to be able to do it, and when it moves forward, the insulating paper is fixed and when it is reversed, the fixing is released.

And, when cutting the insulating paper, the fixing device for preventing deformation and fixing so that it can be cut constantly is installed in the vertical direction, when the insulating paper is transported by pressing the insulating paper by air pressure, and after the insulating paper is cut, the fixing Release it so that the insulation paper to be cut next can be transported.

The insulating paper cutting device is capable of cutting the insulating paper while the cutting paper having a small shape is operated up and down by a cutting cylinder provided vertically.

By using the insulating paper conveying and cutting device having the structure as described above, it is possible to cut a large amount of insulating paper in a short time to improve productivity, and to accurately cut the required length, so that the quality of the product can be uniformly You can do it.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

1 is a schematic front view of an insulating paper conveying and cutting device according to the present invention, and is composed of an insulating paper conveying device 2, a cutting fixing device 3, and an insulating paper cutting device 4 on a support 1.

The insulated paper 5 exits the insulated paper automatic bending device (not shown) and is transported by the insulated paper transport device 2 toward the insulated paper cutting device 4 by the required length.

FIG. 2A is a plan view of the insulating paper conveying apparatus 2 and the cutting fixing apparatus 3 of FIG. 1, and the insulating paper conveying apparatus 2 reciprocates along the guides 6 provided on both sides. When the transfer cylinder (7) is installed at the bottom, the air is supplied to the air inlet (8a) of the left side when moving forward, the air is supplied to the air inlet (8b) of the right side when moving backward, Numeral 3 indicates that the cylinder installed in the vertical direction can be fixed by pressing insulating paper by air pressure.

FIG. 2 (b) is a cross-sectional view taken along the line A-A of the insulator paper conveying apparatus in FIG. 2 (a), wherein a fixing cylinder 9 for insulated paper conveying is provided on the mounting table 10a, and an insulator paper conveying apparatus ( A transfer cylinder 7 is provided to move the back and forth 2) so that the insulating paper 5 is transferred, and the transfer device 2 is capable of reciprocating along the guides 6 provided on both sides.

FIG. 2C is a cross-sectional view taken along line BB of the fixing device 3 for cutting in FIG. 2A, and the cutting cylinder 11 is installed perpendicular to the mounting table 10b to be cut by air pressure. The jar 5 can be pressed and fixed.

(A) and (b) of FIG. 3 show a front view and a side view of the insulating paper cutting device 4 in FIG. 1, in which a cutting machine 13 connected to a cutting cylinder 12 installed vertically has the cutting cylinder ( The insulating paper 5 can be cut while operating up and down by the air pressure supplied to the air inlets 14a and 14b provided at the upper and lower parts of 12).

The operation process of the insulating paper transfer and cutting device having the structure as described above is performed as follows.

After the cutter 13 of the cutting device 4 is raised and the fixing cylinder 11 for cutting is released, the fixing cylinder 9 of the insulating paper feeder 2 fixes the insulating paper 5, When the conveying cylinder 7 conveys the conveying apparatus 2 by the length of the insulating sheet to be cut, the cutting fixed cylinder 11 fixes the insulating sheet and the cutter 13 descends by the cutting cylinder 12 to cut the insulating sheet. Will cut. Then, the transfer device 2 returns to its original position, transfers the insulation paper again, and the cutting process of the cutter is repeated.

On the other hand, this series of processes can be performed sequential by using a limit switch or by using a timer to control the supply of compressed air.

By using the insulating paper conveying and cutting device having the structure and operation as described above, it is possible to cut a large amount of insulating paper in a short time, thereby improving productivity and cutting the product precisely to the required length. It becomes possible to make it uniform.
