Description
Technical field
The utility model relates to capacitor aluminium foil manufacture fields, more particularly to a kind of leading for capacitor aluminium foil production
Electric roller.
Background technique
With the rapid development of domestic electronics industry, aluminium electrolutic capacitor is more widely applied, and performance requirement is also more next
It is higher.It in electronic aluminum foil corrosion processing technology, is rolled using conductive rollers and is contacted with aluminium foil, transmit electric current to aluminium foil.Due to
On this aluminium foil production line, conductive rollers usually will be by very big electric current, and to ensure to have between aluminium foil and conductive rollers certain
Frictional force be therefore usually disposed with a plurality of axially extending silver-colored conductive bar evenly-spacedly on the roller of conductive rollers.This
Cause manufacturing cost very high.
Summary of the invention
The utility model is intended to provide a kind of conductive rollers, and it is high that there are manufacturing costs to solve the problems, such as existing conductive rollers.For
This, the specific technical solution that the utility model uses is as follows:
A kind of conductive rollers, in the production of capacitor aluminium foil, including conductive roller, roll shaft and ring flange, the conduction
Roller is mounted on the roll shaft by the ring flange, is disposed with a plurality of axial direction evenly-spacedly on the conduction roller and is prolonged
The conductive bar stretched, which is characterized in that the conduction roller, roll shaft, ring flange and conductive bar are by copper, copper alloy, stainless steel or aluminium
It is made, one layer of silver powder coating of cold spraying on the upper surface of the conductive bar.
Further, the thickness of silver powder coating is between 0.2 millimeter to 5 millimeters.
Further, the thickness of one layer of silver powder coating of cold spraying on the side of the conductive bar, the silver powder coating is less than institute
State the thickness of the silver powder coating on the upper surface of conductive bar.
Further, the silver powder coating layer thickness on the side of the conductive bar is 0.2 millimeter, the upper table of the conductive bar
Silver powder coating on face with a thickness of 2 millimeters.
Further, one layer of stainless steel powder coating of cold spraying on the side of the conductive bar.
Further, the thickness of stainless steel powder coating is between 0.2 millimeter to 1 millimeter.
The utility model by adopting the above technical scheme, has the beneficial effect that the utility model is led by using in copper
Cold spraying silver powder coating on electric item, can either meet the signal requirement of high current, but can reduce the whole manufactures of conductive rollers at
This.
Detailed description of the invention
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Fig. 1 is the schematic diagram of the conductive rollers of the utility model.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
Referring to Fig.1, the conductive rollers 1 in a kind of production for capacitor aluminium foil are described.Conductive rollers 1 may include conductive roller
10, roll shaft 20 and ring flange 30, conductive roller 10 are mounted on roll shaft 20 by ring flange 30.Uniform intervals on conductive roller 10
It is disposed with a plurality of axially extending conductive bar 40 with opening.Conductive roller 10, roll shaft 20, the shape of ring flange 30 and conductive bar 40 are big
It is small to be well known to the skilled person, it is not discussed herein.Conductive roller 10, roll shaft 20, ring flange 30 and conductive bar 40
It is made of copper, copper alloy, stainless steel or aluminium.In order to improve conductive bar 40 carrying high currents ability, the upper table of conductive bar 40
One layer of silver powder coating 50 of cold spraying on face.Since cold spray process has the coating of spraying good, the sprayable any thickness of compactness
The characteristics of, thus the thickness size of silver powder coating 50 selected according to the actual situation (such as service life, manufacturing cost etc. because
Element).In general, the thickness of silver powder coating 50 can be between 0.2 millimeter to 5 millimeters.
In some cases, in order to further increase conductive bar 40 carrying high currents ability, the side of conductive bar 40
On also one layer of silver powder coating of cold spraying.Since side is not allowed easy to wear, the thickness of the silver powder coating is less than the conductive bar
Upper surface on silver powder coating thickness.In a specific embodiment, the silver powder coating layer thickness on the side of conductive bar 40
Be 0.2 millimeter, and the silver powder coating on the upper surface of conductive bar 40 with a thickness of 2 millimeters.
It is applied in the biggish production technology of some corrosivity in conductive rollers 1, in conductive bar 40 by copper, copper alloy or aluminum
In the case where, in order to improve the corrosion resistance of conductive bar 40, one layer of stainless steel powder coating of cold spraying on the side of conductive bar 40.
Preferably, the thickness of stainless steel powder coating can be between 0.2 millimeter to 1 millimeter.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
