Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a winding device for a toroidal core for use in a VTR or digital camera, and particularly for winding a micro toroidal core such as a magnetic or magnetic core. For [9 suitable toroidal play core 41s! Regarding equipment.

[Background of the invention]

As a prior art for automatically winding a coil around a micro toroidal core such as a magnetic head, Japanese Patent Application Laid-Open No. 58-2OS1
There is a winding device disclosed in Japanese Patent No. 12.

However, in the prior art, the structure is such that the two fingers that grip the material are driven by independent means, so that after inserting the wire into the core hole, the wire is passed through the pupil, Vibrations are generated mechanically or by control in the vicinity of each positioning point. For this reason, when both fingers grip the wire at the same time, a slight movement is applied to the wire in the direction in which it is passed.
This imaging causes the wire to buckle, causing bending at the tip of the wire. As winding is continued, the wire rod repeatedly twitches and the bending force of the wire accumulates. The tip is misaligned by the length of the song.

As the winding is repeated, the amount of positional deviation is 1! There is a problem in that the wire rod cannot be inserted into the core hole.

[Purpose of the invention]

An object of the present invention is to solve the problems of the prior art and to suppress the occurrence of bending of the tip of the wire during winding.

To provide a winding device for a toroidal core which can always smoothly insert a wire into a core hole.

[Summary of the invention]

The present invention provides two grippers that can independently slide and open/close in a direction intersecting the direction of insertion of the wire into the core hole. , these 2-g9. This gripper is characterized by being configured so that the grippers can be moved and rotated together in the insertion direction of the wire rod, and this configuration eliminates the relative movement between the two grippers and improves the speed during winding. The bending of the tip of the wire suppresses the occurrence of scratches, and the wire can always be inserted smoothly into the core hole.
