Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] The following gives specific embodiments.

[0024] Please refer to Figure 1-2As shown in the figure, an electronic transformer winding device includes a support 11, a winding drum 13 and a first motor 14; the winding drum 13 is arranged on the top of the support 11; a synchronous belt is installed between the bottom of the winding drum 13 and the output end of the first motor 14; a turntable 12 is arranged on the top of the support 11; the turntable 12 is rotationally connected to the winding drum 13; a lifting frame is fixedly connected to the top side of the support 11; an electric push rod 15 is fixedly connected to the top of the lifting frame; the output end of the electric push rod 15 is fixedly connected to a wheel seat 16; a wire guiding wheel 17 is rotationally connected to the bottom of the wheel seat 16; the first motor 14 and the turntable 12 are fixedly connected; when in use, the first motor 14 drives the winding drum 13 to rotate through the synchronous belt, the winding drum 13 is used for inserting a transformer bobbin, and the rotation of the winding drum 13 drives the transformer bobbin to rotate, so as to wind and wind copper wires. At the same time, the copper wire passes through the wire guiding wheel 17, and the height of the wire guiding wheel 17 is adjusted synchronously by relying on the electric push rod 15, so as to facilitate winding the copper wire evenly on the transformer bobbin, thereby improving the evenness of winding and facilitating winding the copper wire neatly.

[0025] Further, as Figure 1-3 shown in the figure, the turntable 12 is rotationally connected to the support 11; a second motor 2 is fixedly connected to the support 11; the output end of the second motor 2 is fixedly connected to the turntable 12; a plurality of winding drums 13 and first motors 14 are provided; when in use, both the first motor 14 and the second motor 2 are servo motors, the second motor 2 can drive the turntable 12 to rotate, and by arranging a plurality of winding drums 13, one can be used for inserting a transformer bobbin and the other can be used for removing the transformer bobbin, which can facilitate the cooperation of multiple workers and is convenient for use.

[0026] Further, as Figure 3-5As shown, a plurality of grooves are provided on the reel 13; a vertical rod is slidably connected to the middle of the reel 13; a fixed arm 31 is rotatably connected to the inner side wall of the groove; a pulling rope 32 is fixedly connected between the vertical rod and the fixed arm 31; a torsion spring is installed at the rotational connection of the fixed arm 31; a downward pulling assembly for pulling the vertical rod downward is provided at the bottom of the vertical rod; the downward pulling assembly includes a moving seat 42; the moving seat 42 is rotatably connected to the bottom end of the vertical rod; a guiding seat 41 is fixedly connected to the bottom of the support 11 at a position corresponding to the moving seat 42; a protrusion 43 is provided at a position corresponding to the lifting frame on the guiding seat 41; the moving seat 42 is slidably connected to the guiding seat 41; the moving seat 42 is arranged in a C-shaped structure; during use, the inner diameters of the reel 13 and the transformer bobbin are relatively small, which facilitates the insertion and extraction of the transformer bobbin. When the turntable 12 moves to the lifting frame, the protrusion 43 of the guiding seat 41 will squeeze, causing the moving seat 42 and the vertical rod to move downward. The downward movement of the vertical rod pulls the fixed arm 31 to rotate downward through the pulling rope, so that the fixed arm 31 abuts against the inner wall of the transformer bobbin, thereby fixing it. With the above settings, it is convenient for the staff to insert and extract the transformer bobbin and use it. The torsion spring is used to drive the fixed arm 31 to rotate and reset.

[0027] Further, as Figure 4 shown, the vertical rod includes an upper rod 51 and a lower rod 52; the lower rod 52 is inserted into the upper rod 51 and is slidably connected thereto; the lower rod 52 is rotatably connected to the moving seat 42; one end of the pulling rope 32 away from the fixed arm 31 is fixedly connected to the upper rod 51; a spring is fixedly connected between the upper rod 51 and the lower rod 52; during use, the vertical rod is composed of the upper rod 51 and the lower rod 52, which can be telescopically slid and are connected by a spring. When fixing a transformer bobbin with a relatively small inner diameter, the lower rod 52 will be stretched, causing the spring to be stretched, so it is convenient to fix various specifications of transformer bobbins.

[0028] Further, as Figure 4 shown, a fixed seat 61 is hinged to the top of the fixed arm 31; an elastic member 62 is fixedly connected between the fixed seat 61 and the fixed arm 31; during use, the fixed seat 61 can increase the contact area between the fixed arm 31 and the inner wall of the transformer bobbin, thereby improving the fixing effect and further improving the rotational stability. The elastic member 62 is used to facilitate the reset of the fixed seat 61.

[0029] Further, as Figure 4-5 shown, a pulley 7 is rotatably connected to the bottom of the moving seat 42. During use, the pulley 7 can reduce the friction with the guiding seat 41, thereby reducing wear and facilitating the movement of the moving seat 42.

[0030] Working principle: When in use, the first motor 14 drives the driving reel 13 to rotate synchronously through a synchronous belt. The reel 13 is used for inserting and placing the transformer bobbin. By relying on the rotation of the reel 13, the transformer bobbin is driven to rotate, so as to wind the copper wire. At the same time, the copper wire passes through the wire guide wheel 17, and the height of the wire guide wheel 17 is adjusted synchronously by means of the electric push rod 15, so as to facilitate the uniform winding of the copper wire on the transformer bobbin, thereby improving the uniformity of winding and facilitating the neat winding of the copper wire. When in use, both the first motor 14 and the second motor 2 are servo motors. The second motor 2 can drive the turntable 12 to rotate. By arranging a plurality of reels 13, one can be used for inserting and placing the transformer bobbin, and the other can be used for removing the transformer bobbin, which can facilitate the cooperation of multiple workers and is convenient for use. The inner diameters of the reel 13 and the transformer bobbin are relatively small, which can facilitate the insertion and removal of the transformer bobbin. When the turntable 12 moves to the lifting frame, the protrusion 43 of the guide seat 41 will squeeze, causing the moving seat 42 and the vertical rod to move downward. The downward movement of the vertical rod pulls the fixed arm 31 to rotate downward through stretching, so that the fixed arm 31 abuts against the inner wall of the transformer bobbin, thereby fixing it. With the above settings, it is convenient for workers to insert and remove the transformer bobbin and convenient for workers to use. The torsion spring is used to drive the fixed arm 31 to rotate and reset. When in use, the vertical rod is composed of an upper rod 51 and a lower rod 52, which can slide telescopically and are connected by a spring. When fixing a transformer bobbin with a relatively small inner diameter, the lower rod 52 will be stretched, causing the spring to be stretched, so that it is convenient to fix various specifications of transformer bobbins. By relying on the fixed seat 61, the contact area between the fixed arm 31 and the inner wall of the transformer bobbin can be increased, thereby improving the fixing effect and further improving the rotational stability. And the elastic member 62 is used to facilitate the reset of the fixed seat 61.
