TW201728057A - Coil winding method with enameled wire terminal winding-management function capable of solving the inconvenience problem of manually cutting a finished enameled wire when winding the coil for a motor stator, as well as preventing the winding-management pin from being crooked or broken by a mechanic tensile force - Google Patents

Abstract

A coil winding method with an enameled wire terminal winding-management function, comprising a thread positioning step, an initial segment thinning step, an initial segment winding/positioning step, a magnetic pole arm winding step, an ending segment thinning step, an ending segment winding/position step and a cutting step, or, depending on the phase of the stator after the magnetic pole arm winding step, at least one rotation stator may be added and a magnetics pole arm winding step performed. The initial segment (before the magnetic pole arm winding) and the ending segment (after the magnetic pole arm winding) are respectively subjected to a thinning process, and then the thinned initial segment and ending segment are wound around the winding-management pin, so that wire cutting for the initial segment and the ending segment can be performed by applying a mechanic tensile force (e.g. using gripper and winder). In this way, not only the enameled wire terminal can be neatly wound and handled in the winding-management pin without exposing the wire tail, but also the trimming step can be omitted to simplify the workflow and prevent the winding-management pin from crook and breakage due to the pulling. The initial segment and the ending segment after the thinning process can make the subsequent soldering operations easier.

Description

Coil winding method with enameled wire end winding wire function

The present invention relates to a method for coil winding of a motor stator winding coil, and more particularly to a coil winding method having the function of an enameled wire end winding wire.

At present, the stator coil winding operation of the motor is mainly performed by a winding machine. In the operation of the stator coil wire group of the motor, the stator is mounted on the stator positioning member of the winding machine, and the winding is passed through the winding. The enamelled wire end of the winder output of the machine is fixed on the wire gripper, and then the enameled wire is first wound around the wrap wire end of a magnetic pole arm of the stator, and then the wire of the enameled wire is wound around the stator by the winder. After the number of turns of the arm is predetermined, the enameled wire is wound around the wrap line of the magnetic pole arm, and the enameled wire is broken by a manual cutting means or a mechanical breaking means, or the enameled wire is wound around the wire of the stator in the winder. After the magnetic pole arm is rotated for a predetermined number of turns, the stator is rotated, and then the enameled wire is continuously wound around the other magnetic pole arm until the magnetic pole arm of the connecting wire is wound, and the enameled wire is wound around the magnetic pole arm of the connecting wire to wrap the wire tip, and the manual hand shear The breakage mode or mechanical pull-off method breaks the enameled wire.

However, in the method of uncovering the stator coil winding, the manual cutting method is adopted to break the enameled wire, and the winder must be stopped. The operation is manually performed by the operator, and the operation takes time and labor. As for the mechanical breaking method, the enameled wire is broken, which is simpler than the manual cutting of the enameled wire. However, for the enameled wire with a large wire diameter, the mechanically pulled enameled wire breakage method is liable to cause the twisted wire tip on the stator magnetic pole to be pulled or broken. Furthermore, the above-mentioned breaking method of the enameled wire by the manual cutting method, or the breaking method of the mechanical lacquered enameled wire, will cause the tail end of the enameled wire to protrude outside the tangled wire tip, in order to prevent the enameled wire tail from being exposed to the coil winding. In order to be affected, the operator must manually re-wrap the tail of the enameled wire at the end of the wrap line.

In addition, after the stator magnetic pole coil winding, the enameled wire end still maintains the same wire diameter, and the outer layer has an insulating layer. When the coil of the subsequent stator coil is soldered to the circuit board, the operator must remove the insulating layer of the surface of the enameled wire end of the coil. In order to carry out the welding wire, it is not easy to solder the welding.

The main purpose of the present invention is to provide a coil winding method with the function of enameled wire end winding wire, which solves the inconvenience of mechanically breaking the enameled wire of the magnetic pole coil winding by manual cutting in the stator winding process, or mechanical breaking is completed. When the enameled wire of the magnetic pole coil winding is easy to pull or break the twisted wire tip and the like.

In order to achieve the foregoing purpose, another coil winding method with the function of the enameled wire end tangling line proposed by the present invention utilizes a winding machine to perform a coil winding on a plurality of complex magnetic pole arms, the coil winding method comprising: a line The head positioning step is fixed on the wire gripper by the enamelled wire end of the winder of the winding machine; and the line segment refining step is performed by a processing device to perform a detailed processing method on the predetermined starting line segment of the enameled wire To reduce the cross-sectional area of the starting line segment; a line segment winding positioning step, the winding line segment of the enameled wire is wound around the winding wire tip of the winding starting magnetic pole of the stator; A winding start pole arm winding step is a predetermined number of turns of the winding starting magnetic arm of the winding of the section after the enamelled wire is connected to the starting line by the winder. The at least one rotating stator and the step of performing the magnetic pole arm winding determine the number of repetitions and the magnetic pole arm according to the preset phase of the stator, and each rotating stator and the performing magnetic pole winding step drive the stator to rotate at an angle to make the winding to be wound. The magnetic pole arm is rotated to a predetermined position, and then the enamelled wire is wound by the winder to the predetermined number of turns of the magnetic pole arm until the pole arm of the predetermined knot line completes the winding; a knot segment refining step is passed through the winder Pulling the enameled wire to the processing device, and the processing device applies a refinement processing method to the predetermined knot segment of the enameled wire to reduce the cross-sectional area of the knot segment; a knot segment winding step is performed by the winder The wire segment of the enameled wire is wound around the wire end of the magnetic pole arm of the predetermined wire; and a wire breaking step is performed by applying tension to the wire by the wire winder and the winder respectively The enameled wire is disconnected from the end of the starting line segment wound on the wire end of the winding wire and the end of the knot segment, and the coil winding of the predetermined magnetic pole arm of the stator is completed.

The wire end can be closely attached to the wrap line tip, and the wireless tail protrudes beyond the wrap line tip: as described above, the line segment and the knot line segment which are refined by the enameled wire are respectively arranged around the wrap line tip. When the starting line segment and the connecting line segment of the enameled wire are subjected to tensile force, the enameled wire is broken from the end of the starting line segment wound on the tip of the winding wire and the end of the knot segment, and the wire end of the wire segment and the wire end of the knot segment are closely adhered to the wrap.
