Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insulating coating stripping device, and more particularly, it is an object of the present invention to provide a device that has a simple structure and can easily adjust the position of a cutter so that it can be adapted to thick and thin metal wires.

Generally, a coil L used in electrical equipment is made by winding a metal wire 2 made of copper or the like several times with an insulating coating 1 of polyurethane, enamel, etc. on the outer circumferential surface, as shown in FIG. Both ends of the wire 2 have a structure in which the insulation layer 1 is removed so that they can be connected by soldering, so-called terminal processing has been performed, and such a coil L can be inserted into a hole 4 of a printed circuit board 3, for example. Then, the printed pattern 5 and both ends of the coil L are connected and fixed by soldering.

The present invention relates to a stripping device for insulation repeating for terminal treatment of a coil as described above, and the present invention will be explained based on an embodiment in which this stripping device is applied to a winding machine. 2 is a block diagram of a winding machine to which a stripping device is applied. A is a stripping device that strips the insulation coating 1 of the metal wire 2 on which the insulation coating 1 has been applied, that is, it processes the end of the coil L, and B is a stripping device that applies the insulation coating 1. A wire holding device presses down the metal wire 2 during peeling (end treatment), C is a wire feeding device that sends out a certain amount of the metal wire 2 in one direction, D is a wire cutting device that cuts the metal wire 2, and E is a wire cutting device that cuts the metal wire 2. This is a winding device for forming wires.

FIG. 3 is a simplified explanatory diagram of a winding machine to which the stripping device of the present invention is applied.
rotates, and as a result of this rotation, the cutter 8 mounted on the rotating body 7 moves toward the center using the pin 9 as a fulcrum against the return spring 25 (see Fig. 4) due to centrifugal force, and the cutter 8 is rotated. 8 comes into contact with the metal wire 2 inserted through the center hole 10 of the rotating body T, and the rotating body 7 is moved in a linear direction by a moving member 11 to peel off the insulation layer 1.

(Details of the stripping device A will be described later.) In addition, in the wire holding device B, the holding member 12 is moved by compressed air or the like, and the metal wire 2 is held between the fixed base 13 and the holding member 12. Furthermore, the wire feeding device C rotatably attaches the pressing piece 16 on the movable body 14 with the pin 15,
The pressing piece 16 is pressed against the movable body 14 by the spring 17, thereby pinching the metal wire 2, and the movable body 14 is moved in a linear direction by the moving member 18.
The cutter 19 of the wire cutting device is moved by a cam mechanism or the like to cut the metal wire 2. Furthermore, in the winding device E, the winding member 21 rotates and moves in the axial direction by the driving member 20, winds the metal wire 2 on the winding member 21, and winds the coil L. It is designed to form.

In addition, 22 is a bobbin around which a metal wire 2 coated with an insulating layer 1 is wound, and 23 is a coil storage container.

Furthermore, the detailed configuration of the peeling device A will be explained with reference to FIGS. 4 and 5. On the outer periphery of the rotary body 7, which has a center hole 10 through which the metal wire 2 is inserted, there is a stopper part 2.
A cylindrical stopper member 24 having a hole 4a and a long hole 24b.
Fit the stopper member 24 to the rotating body 7 with the screw 2.
6, and a pair of cutters 8, each consisting of a blade 8b fixed to a mounting base 8a with a screw 8c, are rotatably mounted to the rotary body 7 by means of pins 9 while facing each other. Wrap the return spring 25 around the return spring 2.
5 is fixed to the head 9a of the pin 9, and the other end is fixed to the mounting base 8a of the cutter 8.
This allows the cutter 8 to open the center hole 1 in the center of the rotating body 7.
0, and the mounting base 8a is in a state of engagement with one of the stopper portions 24a of the stopper member 24.

Now, in this state, when the rotating body 7 rotates counterclockwise at high speed, this centrifugal force overcomes the spring force of the return spring 25,
The cutter 8 rotates toward the center of the rotating body T using the pin 9 as a fulcrum and comes into contact with the metal wire 2, and the mounting base 8a of the cutter 8 is attached to another stopper part 24 of the stopper member 24.
a to prevent further rotation of the cutter 8.

Further, the insulating repeat 1 is peeled off by moving the rotary body 7 in a linear direction by the moving member 11 while it is in a rotating state.

When the peeling operation is completed, the rotation of the rotating body 7 is stopped by the operation of the control switch, and as a result, the centrifugal force is released, and the cutter 8 is moved away from the center of the rotating body 7 by the return spring 25. It will rotate and return to its original position.

Further, the stopper member 24 can be rotated within the range of the elongated hole 24b by loosening the screw 26.
By changing the amount of movement toward 0, it is possible to adapt to the wire diameter of the metal wire 2.

That is, in FIG. 4, when the screw 26 is loosened and the stopper member 24 is rotated clockwise, the stopper part 2
4a also rotates clockwise, and as a result, the cutter 8 moves away from the center hole 10 of the rotating body 1, and the movement of the cutter 8 toward the center hole 10 due to centrifugal force becomes shallow, and the metal wire 2 with a large wire diameter When the stopper member 24 is rotated counterclockwise, the cutter 8 comes closer to the center hole 10 of the rotating body 7, and the cutter 8 moves toward the center hole 10 due to centrifugal force. becomes deep and can be adapted to the metal wire 2 having a small wire diameter.

Furthermore, as is clear from FIG. 4, the blade portion 8 of the cutter 8
b has a plurality of mounting holes 8d, of which two holes 8d
The blade part 8b is attached to the mounting base 8a by inserting a screw 8c into the screw 8c, but when the blade part 8b becomes dull, it is necessary to shift the attachment hole 8d of the blade part 8b relative to the screw 8c. This changes the contact position of the blade portion 8b with respect to the metal wire 2, so that one blade portion 8b can be used for a long period of time.

Next, the operation of the above winding machine will be explained with reference to FIG.
First, one end of the metal wire 2 wound around the bobbin 22 is taken out and the winding machine is driven with the wire being connected to the stripping device A1, the wire holding device B1, the wire feeding device C1, the wire cutting device, and the winding device E. , First, the wire holding device B operates to press the metal wire 2.

Next, the peeling device A is driven.

That is, the drive unit 6 of the stripping device A operates to rotate the rotary body 7, whereby the cutter 8 comes into contact with the insulation repeat 1 on the metal wire 2 due to centrifugal force, and in this state, the movable member 11 rotates the rotary body 7. direction away from wire holding device B (direction of arrow X)
As a result, a part of the insulation coating 1 on the metal wire 2 is peeled off, and the exposed length of the metal wire 2 at the end of the coil L (terminus treatment length) is increased by the amount of movement of the rotating body 7. It is determined.

When the peeling work is finished, the rotation of the drive unit 6 is stopped, and
The rotation of the rotating body 7 also stops, the cutter 8 separates from the metal wire 2, and the rotating body 7 and the moving member 11 automatically return to their original positions, and at this time, the wire presser by the wire presser B is released. Next, the wire feeding device C operates, and the moving member 18 moves the movable body 14 in the direction of the arrow Y to feed out a certain amount of metal wire 2. At the same time, the winding device E starts.
When the winding member 21 rotates and moves in the direction of the arrow Z and winds up the fed-out metal wire 2 onto the winding member 21 to form the coil L, the wire feeding device C returns to its original position. At the same time, the cutter 19 of the wire cutting device operates to cut the metal wire 2.
Finally, when the winding member 21 of the winding device E returns to its original position, the coil L formed on the winding member 21 is removed from the winding member 21 and placed inside the coil storage container 23. It is made to fall.

Further, when feeding the wire, the wire feeding device C presses the metal wire 2 against the movable body 14 with the tip of the pressing piece 16 pressed by the spring 17, thereby holding the metal wire 2 between the ends of the metal wire 2. When returning to the original position after wire feeding, the movable body 14 and the pressing piece are moved together with one end of the metal wire 2 wrapped around the winding member 21 of the winding device E. 16 returns, and at this time, the tip of the pressing piece 16 pressed by the spring 17 is no longer hooked on the metal wire 2, and the tip of the pressing piece 16 returns while sliding on the metal wire 2. .

Furthermore, when the metal wire 2 is fed out by the wire feeding device C, the metal wire 2 is pulled out from the bobbin 22, and then the metal wire 2 in a state of repeated insulation to be stripped is positioned in the stripping device A.

Then, by repeating the above-described operations, the coil L is automatically manufactured.

In addition, when cutting the wire, as shown in FIG. 6, the intermediate portion of the exposed portion of the metal wire 2 from which the insulation coating 1 has been peeled off is cut to form the terminal portion of the coil L that is continuously formed. Therefore, the stripping in the stripping device A is performed so as to simultaneously form one of the two terminals of the coil L.

That is, according to the present invention, the stopper member 24 having the stopper part 24a is fixed to the rotating body 7 with the screw 26, and the cutter 8 rotatably attached to the rotating body 7 by the pin 9 is attached to the stopper part 24a. The cutter 8 is engaged with a stopper portion 24a of the member 24, and by loosening the screw 26 and moving the stopper member 24, the position of the cutter 8 relative to the center hole 10 of the rotating body 7 is adjusted. Therefore, its structure is simple, and the position of the cutter 8 that can be adapted to the thickness of the metal wire 2 can be adjusted extremely easily.
