Description

Technical Field

[0001] The invention relates to the technical field of iron core coils, and in particular to an automatic winding device for large coils. Background Art

[0002] The iron core coil is a commonly used electrical component. It has many uses, such as enhancing magnetic field strength, converting voltage and current, and acting as a filter in circuits. Therefore, it is widely used in transformers.

[0003] According to the publication (announcement) number CN116613948A, the publication (announcement) date is 2023.08.18, and the disclosed Chinese patent: A fully automatic coil winding device for a motor rotor, comprising a workbench, a fixed rod, a fixed bracket and a support column, the bottom of the workbench is fixedly connected to a fixed plate, and the inside of the fixed plate is rotatably connected to a screw rod, and the end of the screw rod is fixedly connected to a first motor, and the first motor is fixedly connected to the bottom of the workbench through the bracket, and the top of the workbench is slidably connected to a bearing assembly, the fixed rod is fixedly connected to the top of the bearing assembly, and the top of the fixed rod is movably connected to a limit strip, and the side of the limit strip is threadedly connected to a fastening bolt, and the end of the fastening bolt is fit-connected to the side of the fixed rod, and the top of the bearing assembly is fixedly connected to a positioning assembly, the top of the bearing assembly is rotatably connected to a positioning column, and the side of the positioning column is fixedly connected to an annular loading plate, and the bottom of the positioning column is fixedly installed with a second motor. The device uses a limit assembly to ensure that the copper wire in the limit sleeve can always be stretched tight on the winding drum when the copper wire is pulled out, thereby avoiding the situation where the copper wire becomes loose or even excess copper wire falls on the workbench when the full-automatic coil winding device pulls the copper wire, thereby making the subsequent copper wire winding operation of the winding device smoother, and the limit spring is set so that the inner surface of the arc-shaped resistance plate can always fit the copper wire on the outer surface of the winding drum, thereby further improving the anti-loosening effect of the limit assembly.

[0004] In the prior art including the above patents, the annular core is generally wound with a gear-type annular winding machine when winding the coil.

However, this method can only be used to wind a smaller core. There are many coils on a large core, and a lot of wire is required.

Under the action of gravity, the movable plate 121 moves downward along the vertical portion 126 and gradually moves to the lowermost end of the vertical portion 126. The spring releases elastic potential energy to drive the movable plate 121 to move along the inclined portion 127.

A large coil automatic winding device, characterized in that: The invention comprises a base, on which is arranged: A winding assembly, comprising a movable seat movably mounted on the base, a movable frame movably arranged on the movable seat, the movable seat and the movable frame forming an annular track, and a connecting pipe for supporting a winding roller movably arranged on the annular track; A conveying assembly, comprising a plurality of movable plates movably mounted in the arc-shaped grooves on the base, wherein the base is provided with guide grooves corresponding to the plurality of movable plates one by one and used to guide the movement of the movable plates, wherein the movable plates move along the arc-shaped grooves to rotate the supporting iron core, and the plurality of movable plates alternately move downward and move in the opposite direction along the arc-shaped grooves; The guide groove comprises a horizontal portion, a vertical portion and an inclined portion connecting the horizontal portion and the vertical portion, and a tenon block adapted to the guide groove is arranged on the movable plate; A movable sheet is hinged at the connection between the inclined portion and the horizontal portion, a torsion spring is arranged between the movable sheet and the base, a spring is arranged between the movable plate and the base, and the horizontal portions of the plurality of guide grooves have different lengths; When the movable plate is lifting the iron core to move, the tenon block on the movable plate moves along the horizontal part of the corresponding guide groove, and the spring is stretched until the movable plate moves to the end of the horizontal part. Under the action of gravity, the movable plate moves downward along the vertical part and gradually moves to the lowest end of the vertical part. The spring releases elastic potential energy to drive the movable plate to move along the inclined part. The tenon block gradually pushes the movable plate, so that the movable plate rotates and leaves space for the tenon block to move. The movable plate continues to move and returns to the initial position. The movable plate contacts the tenon block. The movable plate seals the inclined part under the action of the torsion spring. The movable plate contacts the iron core and moves along the horizontal part. The annular rail is internally provided with a first gear ring formed by hinged connection of two annular parts and used to support the connecting pipe, and the movable seat is internally provided with a first bevel gear meshing with the first gear ring; A rotating disk for driving the movable plate to move is rotatably arranged on the base, and a synchronous block extending to the inside of the rotating disk is arranged on the movable plate; The bottom of the rotating disk is provided with synchronization grooves distributed in a circumferential array and adapted to synchronization blocks, and the synchronization blocks are slidably arranged on the movable plate.

2. A large coil automatic winding device according to claim 1, characterized in that: The rotating disk is provided with a plurality of concentrically distributed second gear rings, and the first bevel gear is slidably provided with a second bevel gear meshing with the second gear rings.

3. A large coil automatic winding device according to claim 2, characterized in that: The second bevel gear is provided with a synchronization rod extending to the inside of the first bevel gear, and the movable frame rotates relative to the movable seat to enable the second bevel gear to move relative to the first bevel gear.

4. A large coil automatic winding device according to claim 3, characterized in that: A shift plate is rotatably arranged on the synchronization rod, and a pull rope is arranged between the shift plate and the movable frame.

5. The large coil automatic winding device according to claim 1, characterized in that: A fixing rod for fixing the end of the wire is movably arranged on the rotating disk, and a clamping block for clamping the end of the wire is movably arranged on the fixing rod.

6. A large coil automatic winding device according to claim 5, characterized in that: A push block for driving the clamping block to move is movably arranged on the fixing rod, and the push block abuts against the base to separate the clamping block from the wire.
