Abstract

The present invention relates to a motor coil winding device and, specifically, to a motor coil winding device in which a coil is wound around a former part arranged in parallel at a predetermined interval, and then the winding tension of the wound coil is reduced so that insertion into an insertion tool can be easy, thereby enabling the defect rate occurring during coil insertion to be reduced and improvement in coil production quality to be expected, and, further, adjusting the interval of the former part so that the coil can be wound in correspondence to the required winding size.

Abstract

The present invention relates to a motor coil winding device maintaining coil spacing and, more specifically, to a motor coil winding device in which, while a wire is wound around former parts that are arranged parallel at a predetermined interval so that the coil is wound therearound, the interval of the former parts is kept, thus enabling the spacing of a coil being manufactured to be maintained constant, and the manufactured coil can be easily inserted into an insert tool, and thus the motor coil winding device can be expected to lower a defect rate occurring in a wire insertion process and to improve production quality.

Abstract

The present invention relates to a motor coil winding machine provided with a coil bundle lowering device and, more specifically, to a motor coil winding machine provided with a coil bundle lowering device in which a coil bundle wound on a former is received in an inserting tool and then, before the inserting tool moves, the coil bundle is forcibly moved downward to be completely received into the inserting tool so that the coil bundle inserted into the inserting tool is prevented from being unintentionally separated, thereby improving work efficiency. According to the present invention, the coil bundle wound on the former is received in the inserting tool, and then, before the inserting tool moves, a pair of levers of the coil bundle lowering device approaching from one side are positioned above the coil bundle and forcibly move the coil bundle downward to be completely received into the inserting tool so that the coil bundle inserted into the inserting tool is prevented from being unintentionally separated, thereby improving work efficiency.

Abstract

The present invention relates to a motor coil winding machine capable of taping ends of coils and, more specifically, to a motor coil winding machine capable of taping ends of coils wherein, in the process of winding motor coils, multiple coils are taped into a bundle before being cut so as to prevent the multiple coils from widening or scattering away from each other after being cut, and the taping process is automated by an automatic taping machine, thereby substantially improving the effectiveness of the manufacturing process and the operation efficiency. The present invention is advantageous in that, in the process of winding motor coils, multiple coils are taped into a bundle before being cut so as to prevent the multiple coils from widening or scattering away from each other after being cut, and the taping process is automated by an automatic taping machine, thereby substantially improving the effectiveness of the manufacturing process and the operation efficiency. The present invention is also advantageous in that the operation efficiency can be further improved because ends of coils that have been cut can be stably retained by forceps members and retaining members.
