Abstract
The invention discloses a transformer coil film wrapping and sintering process, comprising the following steps of: removing an oxidation layer on the surface of a copper wire; polishing the outer wall of the copper wire; winding a polyimide wrapping belt on the surface of the copper wire; and enabling the copper wire to pass through a high-frequency spiral induction coil and heat, and controlling a difference value between an instant temperature of the copper wire and a temperature threshold to be within a certain range when the instant temperature of the copper wire reaches the preset temperature threshold. In the transformer coil film wrapping and sintering process, the film can be fully wrapped and evenly sintered and deposited on the copper wire, the adhesiveness of the film wrapping is increased, the coil is prevented from generating a cracking phenomenon when the coil is wound, thereby effectively improving the insulativity and stability of the film wire.
Description
Technical field
The present invention relates to the transformer coil technical field, relate in particular to the wrapped sintering process of a kind of transformer coil film.
Background technology
Electromagnetic wire is motor, electrical equipment, add some points and the supporting basic material industries of industry such as electronic information, communication, and electromagnetic wire mainly be take enamelled wire as main, enamelled wire adding when easily producing pin hole behind man-hour, narrow limit occurs and applying inhomogeneous, bending easy to crack.At present, the film envelope curve substitutes just gradually traditional enamelled wire and uses as electromagnetic wire, but there is following defect in existing film envelope curve: fully equably sintering deposited on conductor, easily cause cracking, tack is poor, insulation property are poor, urgently to be resolved hurrily.
Summary of the invention
Problem for the prior art existence, the present invention proposes the wrapped sintering process of a kind of transformer coil film, can allow Transposed wind fully equably sintering be deposited on copper cash, improve the tack of Transposed wind, avoid the cracking phenomena of coil when coiling, thereby effectively improve insulating properties and the stability of film wire.
The wrapped sintering process of a kind of transformer coil film, comprise the steps:
Remove the oxide layer of copper line surface;
The outer wall of polishing copper cash;
In copper line surface around the polyimides band;
Make copper cash pass through and generate heat in frequency spiral shape induction coil, after the real-time temperature of described copper cash reaches predetermined temperature threshold values, control the real-time temperature of described copper cash and the difference between the temperature threshold values and be in certain limit.
Preferably, described make copper cash in frequency spiral shape induction coil by being specially: make copper cash axially passing through along frequency spiral shape induction coil spiral.
Preferably, the real-time temperature of the described copper cash of described control and the difference between the temperature threshold values are in certain limit and are specially: the real-time temperature of controlling described copper cash equals the temperature threshold values.
Preferably, described temperature threshold values is 350～380 ℃.
Preferably, make copper cash in frequency spiral shape induction coil by the time speed be 6～8m/min.
With prior art first than, the wrapped sintering process of a kind of transformer coil film in the present invention, pass through sintering process, can allow Transposed wind fully equably sintering be deposited on copper cash, improved the tack of Transposed wind, avoid the cracking phenomena of coil when coiling, thereby effectively improve insulating properties and the stability of film wire.
Embodiment
The present invention proposes the wrapped sintering process of a kind of transformer coil film, comprise the steps:
The oxide layer of S1, removal copper line surface.
Concrete, can adopt the mode of machining to remove the oxide layer of copper line surface, perhaps, adopt chemical solvent to soak the oxide layer that the mode of dissolving is removed copper line surface, bonding force between oxide layer and copper body is inadequate, if can not remove ahead of time, can affect the adhesion between follow-up surrounding layer and copper body.
The outer wall of S2, polishing copper cash.
Concrete, be mainly by the means of machining, to remove the burr of copper cash table wall, and copper body surface is polished smooth, thereby increase the adhesion between surrounding layer and copper body.
S3, in copper line surface around the polyimides band.
Concrete, by polyimides band uniform winding in copper line surface.
S4, make copper cash axially passing through and generating heat along frequency spiral shape induction coil spiral, by the time speed be 6～8m/min, after the real-time temperature of described copper cash reaches predetermined temperature threshold values, controlling the real-time temperature of described copper cash and the difference between the temperature threshold values is in certain limit, preferably, the real-time temperature of copper cash equals the temperature threshold values, and it is deposited to copper cash table wall equably that this temperature threshold values is conducive to the polyimides band, and the temperature threshold values is 350～380 ℃.
Concrete, logical high-frequency current in frequency spiral shape induction coil, copper cash passes its internal heat generation, and some points for measuring temperature are set on copper cash.
When the real-time temperature of point for measuring temperature, during lower than the temperature threshold values, make to raise by the electric current of spirality induction coil, thereby make the real-time temperature of point for measuring temperature continue to rise, thereby near the temperature threshold values; When the real-time temperature of point for measuring temperature equals the temperature threshold values, make to remain unchanged by the electric current of spirality induction coil, thereby the real-time temperature of point for measuring temperature is remained unchanged; When the real-time temperature of point for measuring temperature, during higher than the temperature threshold values, make by the current reduction of spirality induction coil, thereby the real-time temperature of point for measuring temperature is reduced, thereby near the temperature threshold values.Thereby controlling the real-time temperature of described copper cash and the difference between the temperature threshold values is in certain limit.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
