Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding method and an apparatus for winding wires in a winding work having a hollow winding hole in an aligned manner.

2. Description of the Related Art In recent years, the need for aligned windings has increased in the windings of magnetic heads for computers.

An example of the conventional winding method described above will be described below with reference to FIG. 1 is a winding work, 2 is a wire rod, 43 is a winding work holding means, and 44 and 45 are guide means for forming a passage path of the wire rod, and the guide means is the winding arrangement direction of the winding work, The winding work is sandwiched and arranged so as to face each other so as to approach the work. Next, the operation will be described. When the wire 2 is inserted into the winding hole of the winding work 1 and pulled out to the other of the winding works, the guide means 44 and 45 move forward to form a passage path for the wire near the winding work and hold the winding work. The means 43 is moved to wind the wire at a predetermined position. After winding, the guide means 44 and 45 are retracted, the wire is inserted again, and the above operation is repeated to perform winding.

Problems to be Solved by the Invention However, in the above-described configuration, in the case of winding of an extremely fine wire having a wire rod diameter of several tens of microns, the wire rod escapes from a minute gap between the winding work and the guide means, and Not only is it difficult to arrange the wires, but it is difficult to constantly apply tension to the wire during winding due to the shape of the winding work.The guide means retracts because the wire is wound and the next insertion operation is performed. After that, the wound wire rod is loosened, and the wire rod moves, which causes a problem that the wire arrangement is not fixed.

In view of the above problems, the present invention has a structure in which a guide member can contact a winding work and a wire that has already been wound in forming a wire path, and the wire is wound at an accurate position, and the winding is performed. The aligned winding is realized by holding the wound wire and preventing displacement due to loosening of the wire.

Means for Solving the Problems In order to solve the above problems, in the present invention, one end of the wire rod is inserted from one side of the winding hole so as to wind the wire rod around a winding work having a hollow winding hole. In a winding method in which a wire rod protruding into the other of the winding holes is drawn, the drawn wire rod is wound, and the tip of the wire rod is inserted again into the winding hole, a predetermined tension is applied to the drawn wire rod. After winding the wire around one side of the winding work while absorbing the wire looseness that occurs when moving to the next insertion operation, the wire rod holding means presses and holds the wire around the one side by the wire rod holding means, When inserting one end of the wire from one side of the winding hole and pulling out the wire protruding to the other side,
The wire rod guide means forms a fixed wire rod passage to maintain the posture of the wire rod, and the winding work is wound while moving in the winding arrangement direction for each winding with respect to the wire rod passage route. Characterized by a line.

Further, according to the present invention, a work holding means that holds a winding work and can be arbitrarily positioned in the arrangement direction of the wire rod, and grips the wire rod at a predetermined distance from one end of the wire rod and inserts the wire rod from one of the winding holes. A winding chuck, a drawing chuck that grips the wire rod inserted by the winding chuck and draws it out to the other of the winding holes, and a predetermined tension is applied to the wire rod drawn by the drawing chuck to wind the wire rod around the winding work. A tension unit, a wire rod holding means for pressing and holding the wire rod wound by the tension unit on the winding work, and a fixed wire rod passage whose tip is movable and comes into contact with the winding work and the already wound wire rod. Having a pair of guide means for forming a wire, and the pair of guide means are arranged at positions opposed to each other in the wire rod arrangement direction of the winding work held by the work holder. Both the moving the workpiece holding means to the wire array direction for winding the wire, further said wire retaining means, the positional relationship between the winding work is provided in the workpiece holding means so as constant.

Effect of the Invention With the above-described configuration, according to the present invention, when winding a wire rod, the movable element provided at the tip of the guide means is brought into contact with the winding work and the already wound wire rod to form a closed wire path, thereby ensuring accurate By winding the wire and holding it by applying a predetermined tension to the wire, the wire holding means presses and holds the wire work and the wire that has already been wound. Has been realized.

Approaches the winding work 1, the driving cylinder of the guide portion 21 operates, and the guide tip 24 contacts the winding work 1 by the driving spring 28 to form a passage for the wire 3. Wire rod 3
Is drawn around a predetermined position of the winding work through the passage path of the wire rod as the pull-out chuck 10 is moved downward by the pull-up chuck vertical direction transfer means 12.
The winding chuck 7 is again moved by the winding chuck vertical transfer means 8
Is moved to a position apart from the pull-out chuck 10 by a predetermined distance, and the wire rod is transferred to the tension unit 18.
When is activated, the guide means 16 and 17 and the wire rod holding means 20 return to their original state. By repeating the above-described operation, aligned winding is performed on the computer head.
