Description

Detailed Description of the Invention The present invention provides a wire assembly tooling of a motor stator wire winding and assembly machine with a winding frame function, moves the winding head forward to wind the electric wire on the wire assembly tooling, and then winds the wire. The present invention relates to a wire guide device for a motor stator winding and assembling machine, which is configured to retreat the wire head and insert the wires wound around the wire assembling tooling into the stator core.

FIGS. 1 and 2 are diagrams schematically showing the motor stator winding and assembling machine. 1 is a winding head that moves back and forth on the track 2; 3 is a flyer attached to the tip of the winding head for winding; 4 is inserted through the winding head 1 and is wound by the flyer 3; 5 is an inserter having a reel 6 around which the wire is wound; 7 is a stator core held on a pallet 8; and 9 is a conveyor. As shown in FIG. 1, this motor stator winding and assembling machine advances the winding head 1 to approach the inserter 5,
In this position, the inserter 5 is inserted by the flyer 3.
After that, the winding head 1 is moved backward, and in the meantime, the stator core 7 is conveyed by the conveyor 9 to a position facing the inserter 5, and the wire assembly tooling 10 of the inserter 5 is advanced. Then, wire assembly is performed by inserting the electric wire 4 wound around the winding frame 6 into the stator core 7. When the wire assembly is completed, the tooling 10 is moved backward, the stator core 7 is sent in the direction of arrow A, and the next electric wire is inserted. To wind the wire, move the winding head in the direction of arrow B in Figure 2.
The winding for the next stator core is carried out by the flyer 3 again.

In this way, in a motor stator wire winding and assembling machine in which the wire assembling tooling has a winding frame function, the winding head needs to be moved forward and backward for a considerable distance, so there is no need to move it back and forth. mosquito,
Even if it gets hot, there is a problem that does not occur with a winding machine that has a short moving distance. In other words, generally in a winding machine,
As shown in FIG. 3, the wire 4 is fed from a wire pack 11 set at a fixed position to the winding head 1 through a guide tube 12. Therefore, in a wire winding and assembling machine that requires the winding head to be moved back and forth a large distance as described above, there is no problem when the winding head 1 is moved back because the distance l between the winding head and the guide tube 12 is short. However, when the winding head 1 moves forward, the distance L becomes longer, as shown in FIG. Therefore, the deflection of the electric wire becomes extremely large in the span L, and the electric wire may be damaged or, in severe cases, may break.

In view of the above problems, the present invention aims to guide the wire to the winding head in a manner that prevents the wire from swinging out and prevents the wire from being damaged or cut even when the winding head moves forward. It is an object of the present invention to provide a wire guiding device that can perform the following steps.

Next, an example of the implementation of the present invention is shown in FIGS. 5 and 6.
The diagram will be explained.

FIG. 5 and FIG. 6 are diagrams showing an embodiment of the present invention.

The wire guide device of the present invention telescopically connects a movable base 17 fixed to a winding head 16 and a fixed base 18 attached to a wire pack (not shown) by a pantograph mechanism 19. That is, in the pantograph mechanism 19, an even number of grid members 19a having appropriate lengths are connected in an X shape by center pins 20, 20', and their tips are connected by side pins 21. Lattice members 19b having half the length of member 19a are connected by side pins 21, and the other end of each pair of lattice members 19b is connected to base pin 2.
2 is connected to the movable base 17 and the fixed base 18, so that the pantograph mechanism 19 can expand and contract between the movable base 17 and the fixed base 18 in accordance with the movement of the winding head 16.

Thus, the electric wire guide tubes 23a and 23b are attached to each cross axis of the pantograph mechanism, that is, each center pin 20 and 20', and the base pin 2
Similarly, the guide tube 23c is attached to 2. The guide tube is made of ceramic, for example, and is fixed perpendicularly to and penetrating the center pin and base pin, so that it is installed linearly at the wire passing position of the pantograph mechanism 19. .

The fixed base 18 has a fixed base fixing member 25 fixed to a wire pack (not shown) on a mount 24 of a wire winding and assembling machine, for example, and directly faces the movable base 17 on the upper part of the fixing member 25. It is fixed with bolts etc. Therefore, this fixing member 25 is also provided with an insertion hole through which the electric wire 26 can be inserted.

Since the center pins 20, 20' and the base pin 22 rotatably connect the lattice members 19a, 19b, there is a risk that they will rotate due to the expansion and contraction movement of the pantograph mechanism 19, and when these pins rotate, each guide tube 23a - 23c may similarly rotate and the guide tube may face in a direction other than the path of the electric wire. However, the guide tube 23c of each base pin 22
, attach the base pin to the movable base 17 using a set screw, etc.
Since it can be fixed to the fixed base 18, it can be fixed so as to match the traveling direction of the electric wire 26.

Therefore, in the present invention, the center pin 20,
A rotation stopper rod 27 is connected to the outer end of 20'. For example, in the illustrated embodiment, center pin 2
0, 20' are extended to the outside of the pantograph mechanism 19 to protrude, and one end of the rotation stopper rod is inserted into the center pin 20 of one of the extension parts, and the screw 29 is inserted.
The pantograph mechanism 1
9 expands and contracts, each center pin 20, 20' does not rotate, so that the guide tubes 23a, 23b always face the path of the electric wire. In addition, in order to prevent the rotation stopper rod 27 from colliding with the fixed base when the pantograph machine 19 is contracted, rod insertion holes 28 are provided at corresponding positions of the rotation stopper rods of the fixed base 18 and the fixed member 25. .

Since the electric wire guide device of the present invention has the above-described configuration, each guide tube 23 of the pantograph mechanism 19
If the wires 26 of a, 23b, and 23c are inserted and set, when the winding head 16 moves forward, the sixth
As shown in the figure, the pantograph mechanism 19 is in an extended state. That is, between the movable base 17 and the fixed base 18, both ends of the pantograph mechanism 19 and each cross axis are lined up at appropriate intervals, so each guide cylinder of the center pins 20, 20' and the base pin 22 is aligned at that position. 23a, 23b,
An electric wire 26 can be led out from 23c.

Next, when the winding head 16 retreats from the above state, the pantograph mechanism 19 is pressed and contracted so that the base pin 22 and the center pins 20, 20' approach each other, as shown by the chain line in FIG. At this time, the rotation stopper rod 27 slides on the center pin 20' while the fixed base 18 and the fixed member 25
center pins 20, 2 through the rod insertion hole 28 of
0' rotation can be braked. Therefore, each guide tube 23a, 23b, 23c can lead out the electric wire 26 over substantially the entire area when the pantograph mechanism 19 is contracted.

Although the illustrated embodiment shows an example in which two intersecting shafts (center pins) of the pantograph mechanism 19 are used, the present invention is not limited to this. For example, the number of grid members 19a of the pantograph mechanism may be increased. If a corresponding cross shaft is installed, a guide cylinder is installed on the cross shaft, and a rotation stopper rod 27 is installed on each cross shaft, even when the winding head 16 moves over a considerable distance, The guide tube allows the electric wire to be easily led out.

As described above, the present invention allows the pantograph mechanism to expand and contract as the winding head moves back and forth, and despite the expansion and contraction, the electric wire is led out through the guide tube attached to the cross shaft, which is prevented from rotating by the rotation prevention rod. Since the electric wire is configured so as to move forward, the electric wire can be prevented from swinging by each guide tube even when the winding head moves forward, so that the electric wire can be guided to the winding head without being damaged or cut.
