Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transformer preparation devices, and in particular relates to a transformer winding device. Background Art
[0002] Winding coils is an important process in transformer production. Now, motors are basically used to clamp and drive the magnetic core to wind the coils. In the process of transformer coil winding, the number of windings usually needs to be controlled according to the requirements of different transformer specifications. Existing transformer winding equipment generally controls the number of windings by controlling the number of rotations of the motor itself. This control method has certain shortcomings. For example, the number of rotations of the motor is not accurately controlled, resulting in inaccurate counting of the number of transformer windings. At the same time, when the 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 motor to reverse, resulting in inaccurate number of windings. Utility Model Content
[0003] Aiming at the technical problem that the number of winding coils in the existing transformer coil winding device is inaccurate, the utility model provides a transformer winding device, which can improve the accuracy of counting the number of transformer coils.
[0004] The utility model provides a transformer winding device, comprising a motor, a rotating shaft, a clamping head, a rotating block, a supporting plate, an abutment rod and a spring, wherein the motor is connected to the rotating shaft, and the rotating shaft is driven by the motor to rotate, one end of the rotating shaft is connected to the clamping head, and the clamping head is used to clamp the transformer core, and the other end of the rotating shaft is connected to the rotating block, the supporting plate is vertically arranged on one side of the rotating block, the abutment rod can be horizontally movably arranged on the supporting plate, the spring is respectively connected to the abutment rod and the supporting plate, a plurality of ratchet teeth are arranged around the outer wall of the rotating block, the end of the abutment rod is an inclined surface, and the end of the abutment rod abuts on the ratchet teeth of the rotating block under the elastic force of the spring to form a one-way rotation limiting structure, a Hall sensor is arranged at the end of the abutment rod, and a magnet block is arranged at the outer periphery of the rotating block.
[0005] Furthermore, a controller is included, and the controller is electrically connected to the motor and the Hall sensor respectively.
[0006] Furthermore, a base is included, and the support plate and the motor are fixed on the base.
[0007] When the transformer winding device is performing the winding operation of the transformer core, the transformer core can be fixed on the clamping head, and the transformer core can be driven to rotate by the motor, and then the winding operation can be performed in cooperation with the copper wire supply device. During the winding process, the rotating block rotates synchronously, and each time the magnet block on the rotating block passes through the end of the abutment rod, the Hall sensor on the abutment rod can sense and record it, so that the actual number of rotations of the transformer core can be directly detected by the Hall sensor. In addition, since the abutment rod elastically abuts against the outer wall of the rotating block, and the outer wall of the rotating block is a ratchet, a unidirectional rotation limiting effect can be formed to avoid motor reversal and ensure the accuracy of the number of winding turns.
