Description

[Detailed Description of the Invention] The present invention relates to an automatic clamp for a wire winding machine that can clamp, cut, and remove wire rods at high speed and reliably.

Conventionally, wire clamping, cutting, and removing devices used for winding wire around bobbins, etc., have been used to clamp the wire, cut it by pulling it in a straight line, and then unclamp (release) it, and use a vacuum cleaner, etc. A common method is to suck in the residual wire, but this method has the disadvantage of requiring a large-capacity suction machine.

The purpose of the present invention is to eliminate such drawbacks and to prevent clamping, cutting, and
An object of the present invention is to provide an automatic wire clamping, cutting, and removing device that can perform removal work reliably and efficiently.

In order to achieve the above object, the present invention provides a pair of wire rod clamps attached to a wire rod clamp guide, the pair of wire rod clamps being rotatable, and one of the wire rod clamps being rotatable in the axial direction of the wire rod clamp guide. The wire rod is slidable, and the wire rod held between the pair of wire rod clamps is cut by rotating the pair of wire rod clamps, and the held wire rod is released by sliding one of the wire rod clamps, The wire rod attached to the wire rod clamp during cutting is removed by air blowing and its own weight.

The drawings are for explaining one embodiment of the present invention, and the bobbin 1 with a terminal is mounted on a winding shaft, and winding is performed by rotating it in the direction of the arrow.
The winding/terminal winding nozzle 2 can move freely in the X, Y, and Z axis directions by numerical (NC) control, etc., and performs traverse during terminal winding and winding. Between the wire clamps 4 and 5,
The surroundings can also operate in the same way. The shaft of the wire clamp 4 is guided by the wire clamp guide 3, and can be moved forward and backward (front: unclamping, rear: clamping), and can also rotate approximately 180 degrees. Further, the back and forth movement can be performed before, after and during rotation of 180 degrees.
The clamp 5 is constructed to be able to rotate only 180 degrees, and this rotation can only be performed at the same timing as the clamp 4. Incidentally, the wire clamping portions of these clamps 4 and 5 are treated with a discharge coating, which serves to prevent the wires from sagging. The air nozzle 6 is designed to rotate the wire clamps 4 and 5, and then blow air only when the clamp 4 is in the unclamped state.The nozzle 6 has the role of removing residual wire. 4 and 5, and wrap it around the terminal of bobbin 1. Then, remove the wire (remaining wire) that was attached to the wire clamp when cutting the wire after winding it around the bobbin last time. , remove it from the surface of the wire clamp.For this purpose, remove the wire clamps 4 and 5.
Rotate 180 degrees, move the wire clamp 4 forward, and at the same time blow air from the air nozzle to make the remaining wire fall. Next, the bobbin 1 is rotated to wind the wire, and then the wire is tied to the terminal again. Wire clamps 4 and 5 are 180
Rotate it back. The nozzle 2 then passes between the clamps 4 and 5. Clamp 4 is moved back to clamp the wire. Furthermore, rotate clamps 4 and 5 by 180° to perform cutting, and then immediately remove clamps 4 and 5.
Rotate back 180 degrees. At this time, as described above, residual lines adhere to the surface of the wire clamp. For this reason,
Unclamping is performed by moving the wire clamp 4 forward, and residual wires that have adhered are removed by blowing air. This completes the work of winding the wire on the bobbin with the terminal, tying it off, cutting it, and removing the remaining wires.

Next, automatically replace bobbin 1 with a new bobbin,
Repeat the same steps in sequence.

According to an embodiment of the present invention, since the device can be made compact and can be applied to a multi-axis winding machine, it is possible to produce high-speed and high-quality coils.

As explained above, according to the present invention, a series of operations using the wire's own weight and air blowing during clamping of the wire, cutting by rotation, and unclamping can be automated, so it is highly reliable and has the effect of high-speed processing. .

Furthermore, the automatic wire clamping, cutting, and residual wire removal mechanism of the present invention can be installed in a multi-axis winding machine, which has the effect of producing high-quality coils at high speed.
