Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transformer preparation devices, and in particular relates to a coil winding anti-reversal device. Background Art
[0002] Winding coils is an important process in transformer production. Now, basically, a drive motor is used to clamp and drive the magnetic core to wind the coils. In the process of transformer coil winding, it is usually necessary to control the number of winding turns according to the requirements of different transformer specifications. Existing transformer winding equipment generally controls the number of winding turns by controlling the number of rotations of the drive motor itself. This control method has certain shortcomings. For example, the number of rotations of the drive motor is not accurately controlled, resulting in inaccurate counting of the number of transformer windings. At the same time, when the drive motor stops winding, due to the linkage of other equipment, such as the action of the wire cutting device, the copper wire will be pulled, which will cause the drive motor to reverse, resulting in inaccurate number of winding turns. Utility Model Content
[0003] Aiming at the technical problem that the existing transformer coil winding device has inaccurate winding number, the utility model provides a coil winding anti-reversal device, which can improve the accuracy of transformer coil winding number counting.
[0004] The utility model provides a coil winding anti-reversal device, comprising a driving motor, a rotating shaft, a magnetic core clamp, a turntable, a magnetic block, a mounting seat, a hook and a Hall sensor, wherein the driving motor is connected to the rotating shaft, and the rotating shaft is driven to rotate by the driving motor, one end of the rotating shaft is connected to the magnetic core clamp, and the magnetic core clamp is used to clamp the transformer core, and the other end of the rotating shaft is connected to the turntable, and a plurality of ratchets are arranged around the outer wall of the turntable, the mounting seat is located on the upper side of the turntable, the top end of the hook is rotatably connected to the mounting seat, and the bottom end of the hook abuts against the ratchet of the turntable under the action of gravity to form a one-way rotation limiting structure, the Hall sensor is arranged on a side of the mounting seat close to the turntable, and the magnetic block is arranged at the outer peripheral position of the turntable.
[0005] Furthermore, the coil winding anti-reversal device also includes a controller, and the controller is electrically connected to the drive motor and the Hall sensor respectively.
[0006] Furthermore, the coil winding anti-reversal device also includes a support frame, and the drive motor and the mounting seat are both fixed on the support frame.
[0007] When the coil winding anti-reversal device is performing the winding operation of the transformer core, the transformer core can be fixed on the core clamp, and the transformer core is driven to rotate by the driving motor, and then the winding operation is performed in cooperation with the copper wire supply device. During the winding process, the turntable rotates synchronously, and each time the magnetic block on the turntable passes through the Hall sensor, the Hall sensor can sense and record, so that the actual number of rotations of the transformer core can be directly detected by the Hall sensor. In addition, since the hook abuts against the outer wall of the turntable through gravity, and the outer wall of the turntable is a ratchet, a unidirectional rotation limiting effect can be formed to avoid the reversal of the driving motor and ensure the accuracy of the number of winding coils.
