Description

Winding device of coil Technical Field The utility model relates to the field of winding machines, in particular to a winding device of a coil. Background The winding machine is used for winding a wire or a cable on a shaft, is widely applied to industries such as electronics, electricity, communication, automobiles and the like, the wire wound by the winding machine is mostly an inductance coil of an electronic product and an electric product, the surface material of the coil is usually an insulating material for protecting the coil and preventing short circuit, and the wire outlet part of the winding machine can generate shearing stress with the wire in the winding process of the winding machine, so that the wire can locally generate shearing deformation, fatigue damage and crack expansion of the wire, the insulating material on the surface of the coil is damaged, the insulating performance of the coil is influenced, the short circuit is caused between the coil and other parts, and the risk of motor faults is increased. Disclosure of utility model The present utility model is directed to a winding device for a coil, which overcomes the above-mentioned drawbacks of the prior art. The winding device of the coil comprises a workbench and a winding mechanism, wherein the winding mechanism comprises a tubular wire outlet device and a driving assembly for driving the wire outlet device to rotate, one end of the wire outlet device, which is used for outlet wire, is provided with a plurality of balls which are circumferentially distributed by taking the axis of the wire outlet device as the center in a rolling way, the number of the balls is more than two, and a conducting wire is positioned among the balls. Through the technical scheme, the rolling balls are arranged at one end of the outgoing line of the wire outlet device in a rolling way, so that the friction force between the coil and the port of the wire outlet device is converted into rolling friction from sliding friction, and the friction loss of the coil in the winding process is reduced. The utility model is further characterized in that a plurality of hemispherical notches are formed in the inner wall of the outlet at the end part of the outlet, and the balls are rotationally connected in the hemispherical notches. Through foretell technical scheme, the ball rotates to be connected in the hemisphere notch for the ball is more stable when rolling motion, is difficult for taking place the skew. The utility model is further arranged that the distance between the center of the ball and one end of the pipe body, which is far away from the outlet, in the edge of the inner side of the outlet is smaller than the radius of the ball. Through foretell technical scheme, can make the ball expose in the body, prevent at the wire winding in-process, the wire takes place shear stress friction with the edge right angle of body, causes wearing and tearing. The wire outlet comprises a ball base and a ball buckle cover, wherein the ball base is fixed on the end face of the pipe body, the ball buckle cover is detachably connected to the ball base, and the hemispherical notch is formed in the ball base and the ball buckle cover respectively. Through foretell technical scheme, make the installation of ball buckle closure can be more convenient tear open on the ball base. The utility model is further arranged such that the minimum distance between any two adjacent balls is less than the diameter of the wire. Through foretell technical scheme, prevent that the wire from deviating out the clearance between the adjacent ball at wire winding in-process, avoid wire and body direct contact, increase the friction that it received. The utility model is further characterized in that a wire fixing device is arranged below the wire outlet, a wire guide wall is arranged on one side, far away from the wire outlet, of the wire fixing device, and one side, close to the wire outlet, of the wire guide wall is a cambered surface subjected to surface polishing treatment. Through the technical scheme, the polishing treatment of the cambered surfaces of the wire fixing device and the wire guide can reduce the friction force on the surfaces of the wire fixing device and the wire guide, so that the winding is smoother. The wire-winding device has the beneficial effects that the ball is arranged at the port of the wire-winding device, so that the contact area between the coil and the wire-winding device can be reduced, the friction between the wire-winding device and the coil can be reduced, the friction loss of the coil in the wire-winding process can be reduced, meanwhile, the ball is exposed out of the tube body, the shearing stress of the wire and the edge right angle of the wall in the wire-winding process can be prevented, and the abrasion risk of the wire can be increased.
