Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bobbin rotation type winding device, in which winding wire, wiring, and lead wires are wound around the terminals of the coil bobbin, the terminals of which are perpendicular to the winding axis. It can be used effectively when forming a coil by repeatedly cutting the lead wire several times, and is especially effective when winding a coil bobbin with many terminals and wanting to minimize the length of the terminal hair after cutting the lead wire. This is a means of mechanization.

As shown in Fig. 1, recent coil bobbins have a large number of terminals 2 embedded in the flanges 1' of the coil bobbin 1, a large number of winding parts 3, and the same coil bobbin 1 is divided into many parts. More and more things need to be wound.

Conventionally, as shown in FIGS. 2a and 2b, this type of winding device for a coil bobbin 1 has been used to wind a coil around a terminal 2 on which one coil has already been wound and a lead wire portion 4 of the wire is wound thereon. Then, after winding the wire 6, one end of which is held by the chucks 5, 5', around the terminal 2 of the guide nozzle 7,
- When removing the excess wire 6 of the lead wire portion on the A' wire with a cutter, there was a risk of cutting the lead wire 8 of the other terminal 2 and the connecting wire 9 between the winding layers. The above operation was explained for the winding start line, but the same applies to cutting the winding end line.

For the above reasons, when winding several coils on the same coil bobbin 1, the winding and winding are done by a machine and the lead wire cutting is done manually, or the lead wire cutting is done outside the coil bobbin. The long lead wires were processed in a later process. In any case, the efficiency of winding work is low on one hand, and the lead wire processing on the other hand is troublesome, and efficiency becomes extremely low when there are a plurality of winding wires and wires. When dealing with a wide variety of products, there are drawbacks such as difficulty in processing lead wires that are suitable for the terminals.

Also, as shown in Fig. 2a, chucks 5, 5'
Depending on the positional relationship between the terminal 2 and the terminal 2, the direction of the whiskers of the wire 6 wound around the terminal 2 after cutting differs considerably, and the direction of the straight line connecting the terminal 2 and the chucks 5 and 5' is different from the straight line A-A'. The more the angle differs from the right angle, the longer the hairline becomes, which causes inconvenience when assembling the coil bobbin 1 and other parts, so a hair removal process is necessary.

The present invention aims to eliminate the above-mentioned conventional drawbacks and to provide a highly versatile and high quality winding device.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

It is configured to mesh with the spur gear 39. That is, when the rotary table 19 is indexed and rotated and set in the winding station, the spur gear 34 of the drive shaft 31 that has come to the winding station meshes with the spur gear 39, and rotational force is transmitted. ing.
