Description

Technical Field

[0001] The invention relates to the technical field of coil winding, in particular to an automatic winding device for an automobile ignition coil. Background Art

[0002] Coil usually refers to a ring-shaped wire winding. The most common coil applications are: motors, inductors, transformers and loop antennas. The coil in the circuit refers to the inductor. It means that the wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow or contain an iron core or a magnetic powder core, which is referred to as inductance. Inductance can be divided into fixed inductance and variable inductance. Fixed inductance coil is referred to as inductance or coil. The capacitance between turns of the coil, between the coil and the shielding cover, and between the coil and the bottom plate is called distributed capacitance. The existence of distributed capacitance reduces the Q value of the coil and deteriorates the stability. Therefore, the smaller the distributed capacitance of the coil, the better. Before winding, you need to apply a layer of alcohol on the self-adhesive wire, because the self-adhesive wire itself has a layer of chemical substance on the surface. When the chemical substance encounters alcohol, it becomes sticky, so it can make the wires more tightly wound.

[0003] However, the coating structure currently used is usually complex in structure, high in cost, and not very convenient to operate. The coating area is not uniform during coating, and the tensioning force of the wound wire on the iron core is greatly affected by the structure when the wire is wound, making it inconvenient to maintain consistency.

[0015] The present invention provides an automatic winding device for an automobile ignition coil, which has the following beneficial effects:

[0016] 1. The automatic winding device for an ignition coil for an automobile places an iron core on a supporting plate inside a positioning device, drives the air cylinder to move downward by rotating the lifting structure inside the bracket, drives the extrusion plate to be squeezed on the top of the iron core, and inserts the positioning airbag into the inside of the iron core at the same time, and then inflates the inside of the air cylinder through an air nozzle, and the air inside the air cylinder enters the inside of the positioning airbag through the air cavity, the positioning airbag expands and pushes the extrusion pad to be squeezed on the inner wall of the iron core, and then the wire to be wound passes through the guide device and is fixed on the iron core, at this time, the supporting plate is driven to rotate by a driving motor, and the supporting plate drives the iron core to rotate by friction to be wound, and the extrusion of the extrusion plate and the supporting plate can fix the iron cores of different shapes and sizes, so that the application range of the device is wider, and at the same time, the positioning airbag can be inserted into the inside of the iron core, and the extrusion pad can be pressed against the inner wall of the iron core to make the fixation of the iron core more stable, so that the device can not only fix the iron cores of different shapes and sizes, but also has better stability of fixation.

[0017] 2. The automatic winding device for the automotive ignition coil is provided with a guiding device. When in use, the wire to be wound is passed through the processing device and the guiding ring, and then hydraulic oil is injected into the hydraulic chamber through a small hydraulic cylinder. The pressure pushes the hydraulic telescopic rod to extend, and the hydraulic telescopic rod drives the friction pad to be pressed against the side of the wire, thereby applying tension to the wire between the positioning device and the guiding device, so that the wire can maintain a certain tension when it is wound on the iron core, avoiding the situation where the wound wire is loose. At the same time, the tension can also be freely adjusted by the pressure inside the hydraulic chamber, which is convenient to use. In addition, since the tension is controlled by the friction between the friction pad and the wire, the tension of the wire at different positions on the iron core can be kept consistent.

[0018] 3. The automatic winding equipment for automobile ignition coils is provided with a processing device. When in use, the wire is passed through the conical guide ring and the sponge ring, and the alcohol inside the liquid storage tank enters the coating cavity and flows to the sponge ring through the discharge pipe. When the wire moves inside the sponge ring, the alcohol can be smeared on the wire through the sponge ring. Since the sponge ring completely wraps the wire, the alcohol can be smeared on the wire more evenly.

[0019] 4. The automatic winding device for the automotive ignition coil is provided with a toggle ring and a conical guide ring. Since the conical guide ring is concentrically arranged with the sponge ring, when the wire is inserted, it can be guided by the conical guide ring. The wire first passes through the conical guide ring and then through the sponge ring, making the threading operation more convenient. At the same time, the toggle ring can be driven to rotate by rotating the conical guide ring, and the toggle ring drives the plug to rotate, thereby rotating the plug to one end of the drain pipe to block one end of the drain pipe, so that the device can prevent alcohol from being lost from the inside of the drain pipe when not in use, and the operation is also relatively convenient.
