[0003] However, in actual application, the above device still has the following problems: when the first rotating motor drives the winding frame to rotate and wind, the second rotating motor drives the second rotating shaft to rotate and unwind. Due to the lack of a guiding structure for the coil wire, the coil wound on the winding frame is not wound evenly, affecting the quality of the hollow coil. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic winding device for a transformer coil in view of the above-mentioned shortcomings. By providing a guiding mechanism, the coil wire can be evenly wound onto a jig, thereby avoiding the situation in which the coil quality is affected by uneven coil winding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transformer coil automatic winding device comprises a base, a winding frame, a guide frame and a controller arranged on the base, a shrinking jig rotatably connected to the winding frame, a guide ring slidably connected to the guide frame, a motor fixed to the winding frame, a transmission mechanism 1 used to connect the motor output shaft and the shrinking jig, and a transmission mechanism 2 used to connect the motor output shaft and the guide ring, wherein the shrinking jig and the motor are electrically connected to the controller.

[0007] Furthermore, a driving shaft is connected to the output shaft of the motor via a coupling, and the motor is connected to the transmission mechanism 1 and the transmission mechanism 2 via the driving shaft.

[0008] Furthermore, the contraction jig includes an inflatable shaft rotatably connected to the winding frame through a bearing, an inflatable cavity arranged in the inflatable shaft, an airbag arranged in the inflatable cavity, and an air tube connected to the airbag at one end. Four through grooves are radially opened on the inflatable shaft, and a telescopic slide key is slidably connected in the through groove. One end of the telescopic slide key extends into the inflatable cavity and is fixed on the airbag. After the other end of the telescopic slide key extends out of the through groove, it is connected with an arc-shaped abutting piece. The outer arc surfaces of the four arc-shaped abutting pieces are combined to form a winding frame. When the telescopic slide key is in a retracted state, the inner arc surface of the arc-shaped abutting piece abuts against the outer arc surface of the inflatable shaft.

[0009] Furthermore, the transmission mechanism 1 includes a driving wheel 1 arranged on the driving shaft, a driven wheel 1 arranged on the inflatable shaft, and a belt 1 used to connect the driving wheel 1 and the driven wheel 1.

[0010] Further, the second transmission mechanism includes a guide shaft rotatably connected to the guide frame, a guide rod arranged parallel to the guide shaft, a guide seat slidably connected to the guide rod, a second driving wheel arranged on the driving shaft, a second driven wheel arranged on the guide shaft, and a belt two used to connect the second driving wheel and the second driven wheel. The guide shaft is arranged parallel to the inflatable shaft, and an annular guide groove is arranged on the guide shaft. The two opposite ends of the annular guide groove extend toward the two ends of the guide shaft with the axis of the guide shaft as the center, and a slider is slidably connected in the annular guide groove. After one end of the slider extends out of the annular guide groove, it is connected to the guide seat, and the guide ring is fixed on the guide seat.

[0011] The beneficial effects of the utility model are:

[0012] In practical applications, one end of the coil wire is passed through the guide ring and then wound onto the shrinking jig. During the process of the shrinking jig being driven to rotate by the motor through the transmission mechanism 1, the motor drives the guide ring to slide through the transmission mechanism 2, thereby guiding the coil wire to be evenly wound onto the shrinking jig. After the winding is completed, the shrinking jig is shrunk so that the hollow coil after winding can be easily removed. The utility model is provided with a guiding mechanism so that the coil wire can be evenly wound onto the jig, thereby avoiding the situation where the coil quality is affected by uneven coil winding.
