Abstract: In a multilayer coil which winds “n” wire rods (4) (“n” is an integer number of two or more) in line around a winding core (2) having a cross section of a polygonal shape. An intersection portion (5) is formed on a face where feeding of the winding core is made by feeding the wire rods by an amount of “n” wire rods during a period when the wire rods (4) are wound by one round around the winding core (2), so that the wire rods in a lower layer and an upper layer intersect therein. A twist portion (6) is formed at an end of at least one face out of the faces where the feeding is made, wherein two wire rods out of “n” wire rods are twisted to replace an arrangement of the wire rods.

Abstract: A winding device winds a wire (90) onto a core (8) having a plurality of teeth (8b) protruding from a yoke and having slots (8a) formed between each tooth (8b). The winding device winds the wire (90) by causing a nozzle (3) which lets out the wire (90) to perform a relative motion. The winding device is provided with pusher plates (72) which guide the wire (90) into the slots (8a), and inserts the wire (90) into the slots (8a) by causing the pusher plates (72) to move relative to the core (8).

Abstract: This invention provides a coil winder which can shorten the time required to wind coils. The coil winder has a nozzle for feeding out a wire, a stator support base, a head for supporting the nozzle free to move radially relative to the rotation axis of the stator support base, a head support shaft which supports the head and extends axially, a head support shaft displacement mechanism for moving the head support shaft to and fro axially, a head support shaft rotating mechanism for rotating the head support shaft around the axis, a traverse shaft which passes through the head support shaft, a traverse shaft rotating mechanism for rotating the traverse shaft, and a nozzle displacement device for displacing the nozzle radially relative to the axis due to the relative rotation of the traverse shaft with respect to the head support shaft. Motors provided for the head support shaft rotating mechanism and the traverse shaft rotating mechanism are supported by a frame.

Abstract: A coil winding apparatus 1 includes a transvers mechanism which displaces a wire supply part 8 and a spinds 5 to which a bobbin 4 is fitted relative to each other in an axial direction. This traverse mechanism includes a first traverse mechanism 11 and a second traverse mechanism 15 which have a different displacement range and displacement pitch. The first traverse mechanism 11 and second traversemechanism 15 are displaced independently of one another, so even when a wire of fine diameter is rapidly wound on a narrow width, the coil winding alignment does not break down, and the coil turns can be wound at high speed in an orderly arrangement.

Abstract: A winding machine, as a ball screw mechanism for moving a nozzle section (10) in three dimensional directions, comprises a lateral movement mechanism (20), a lengthwise movement mechanism (30), a vertical movement mechanism (40), and a nozzle lateral movement mechanism (50). The lateral movement mechanism (20) supports the lengthwise movement mechanism (30), and the lengthwise movement mechanism (20) supports the vertical movement mechanism (40) and the nozzle lateral movement mechanism (50) at the lengthwise movement mechanism (30). A support plate (12) of the nozzle section (10) is directly connected to a vertical movement member (44) of the vertical movement mechanism (40) via a rail (47) and a rail groove (12A) and directly connected to a lateral movement member (54) of the lateral movement mechanism (50) via a guide (57) and a sliding member (14).

Abstract: An actuator for a magnetic head of a disk device has a rotating arm constructed of resin. The arm is supported rotatably in a housing on an electrically conducting shaft, and a magnetic head supported by a supporting member at one end of the arm is moved to various positions above the magnetic disk when the arm is rotated by a rotating mechanism. An electrically conducting mechanism conducts static electricity from the supporting member of the magnetic head to the shaft so that static electricity is prevented from accumulating on the head supporting member of the resin arm or in its vicinity.

Abstract: An arm unit for a hard disk drive is made by assembling together a plurality of stacked arms, a bearing member for supporting the arm unit upon a pivot shaft, and a coil for providing a magnetic force to swing the arm unit around the pivot shaft. Spacers are provided between the arms, and structural are provided for maintaining gaps between the arms and the spacers. Holes formed in the arms and in the spacers receive the bearing member while maintaining a predetermined gap. These assembled elements are then arranged within a mold and are fixed together into one unitary body by resin injected into the mold. By this construction, the assembly of the unit into the mold is facilitated, and the manufacturing cost of the arm unit is reduced.

Abstract: An automatic coil winder comprises a spindle on which a bobbin is mounted for rotation, and a nozzle for supplying a wire to the bobbin. The coil winder comprises a first arm and a second arm which move respectively in triaxial directions. The nozzle is supported on the first arm while a plurality of auxiliary tools are supported on the second arm. Two arms move the nozzle and the auxiliary tools independently, whereby the winding work to the bobbin can be efficiently carried out.

Abstract: An automatic coil winder provided with a turret having a rotation axle for carrying a bobbin and a motor for rotating this rotation axle, and provided with a nozzle for supplying wire to the bobbin, further comprises a mechanism for rotating the turret and a mechanism for fixing the turret in a predetermined rotation position. The rotation axis of the bobbin can therefore be inclined depending on the projection direction of a terminal pin on the bobbin, and the tying of the wire around the pin can be easily accomplished. By providing a displacement mechanism which can displace the turret in three dimensions, it is easy to adapt to operations other than winding such as soldering wire to the terminal pin or taping it to the bobbin, and the entire series of coil manufacturing processes can be automated.

The winding unit includes a nozzle bar, a nozzle device provided on the nozzle bar for supplying the wire, a clamping device on the nozzle bar for holding an end of the wire and a nozzle displacement device for supporting the nozzle bar and moving it in three dimensions.
