Field of the Invention [0001] The present invention relates to a motor coil winding machine capable of taping at the end of a coil, and more particularly, to a motor coil winding machine in which a plurality of coils are cut by taping The present invention relates to a motor coil winding machine capable of taping the end of a coil so as to improve the efficiency of the manufacturing process and the work efficiency by automating the taping process through the automatic tapping machine while preventing the coils of the strands from spreading or scattering.

Generally, a motor is a device for obtaining rotational power by converting electrical energy into mechanical energy, and is widely used not only for household electric appliances, but also for electric automobile equipment and industrial equipment. Such a motor is a main component in which a coil is wound around a stator and a rotor rotatably installed with a gap in the stator.

In this case, a method of winding the coil on the stator is a method in which the coil is wound directly on the stator and a method in which the coil is first wound in a predetermined shape and inserted into the insertion groove formed between the teeth and the teeth formed on the inner wall of the stator. It is common to wind the coil. The winding method of the coil is wound by the winding machine.

A known conventional coil winding machine has a structure in which a plurality of coils are wound around a forma when the pliers supplied with the coils are rotated around the forma. When a certain amount is wound, the ends are cut, After inserting it in the tool, the coil is wound on the forma again, and when it is wound a certain amount, the end is cut again. Since the coils to be wound at this time are several strands, there is a phenomenon that the strands of the coils are widened or scattered from each other after the cutting, and there is a considerable inconvenience in the winding process as well as the subsequent process. There has been a disadvantage in that it is necessary to manually work to fix a plurality of strands of coils by twisting them to form a bundle.

8, in order to wind a plurality of strands of coils C onto the forma 200, a feed is performed from the upper side through the inside of the one side pliers 300, As shown in Fig. Then, the clamp cylinder 730 of the clamp member 700 provided at the lower side is moved back and forth and upward to catch the coil C. Here, it is a matter of course that the positioning of the clamping cylinder 730 is set by a controller and a sensor not shown.

9, when the clamping cylinder 730 grasps the coil C, the automatic tapping machine 630 is moved downward and backward and forward in the lateral direction so that a plurality of strands of coils C are wound Taping is performed so as to be bundled and returned to the original position. 10, the pliers 300 rotate along the outer periphery of the pillar 200 to start winding the coil C, and the coil C is wound several times, preferably about two to three turns, The clamping member 730 of the clamping member 700 is operated downward while gripping the coil C. As a result, The downwardly-operated coil C is inserted between a pair of columns of a fixing member 800 provided at the edge of the upper plate 510 of the rotary table 500, and the blocking plate 820 is opened, The inner plate 830 is supported by the elastic member 840 so as to mitigate the impact. At the same time, the open plate 820 is restored and closed, It is constrained so as not to be detached to the outside.

In this operation, the pliers 300 continuously wind the coil C on the outer periphery of the pillar 200. The pillar 200 is wound around the pillar 200 in accordance with the rotation of the plier 300 so that the coil C can be sequentially wound. ) Is gradually lowered, and the coil C wound by the inserting tool T placed in the lower rotary table 500 is inserted by the downward movement.
