Description

A coil winding limiting device

Technical field

The utility model belongs to the technical field of transformer production equipment, and specifically relates to a coil winding limiting device.

Background technique

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is widely used in industry, agriculture, transportation, urban communities and other fields. The main components of the transformer are: primary coil, secondary coil and iron core.

When producing a transformer, wires need to be wound around the coil bobbin to form a coil. The steps for winding a coil are usually as follows: first, fix the coil bobbin on the mounting shaft driven by the motor, and then fix the wire ends of the wires on the coil bobbin; then let the motor drive the coil bobbin to rotate, and form a limiting guide for the wire. The wheel moves parallel to the axial direction of the coil bobbin; in this way, the wire can be evenly wound around the circumference of the coil bobbin.

After the existing winding device completes the preset number of turns, the winding is usually stopped by cutting off the power to the motor. The motor has rotational inertia after the power is cut off. Therefore, in actual operation, the coil is often caused by the rotational inertia of the motor. The actual number of turns is higher than the preset number of turns.
