Description

Roller for machining metal foil
Technical field
The present invention relates to a kind of roller for machining metal foil.In more detail, the present invention relates generally to and constitutes the improvement of metal material that the surface is formed with the roller for machining metal foil of a plurality of recesses.
Background technology
All the time, in order to be that tens of microns metal foil surface forms protuberance at thickness, generally adopt plating method, etching etc.But, when adopting these methods at every 1cm 2Metal foil surface on form tens of and even hundreds of when having the protuberance of micron unit-sized, must comprise the Precision Machining of a plurality of operations, need numerous and diverse operation, thereby required time is very long.Nonetheless, the rate of still can not fully reducing the number of rejects and seconds.The liquid waste processing that is accompanied by the use of plating liquid, etchant etc. and produces also becomes problem.In addition, also insufficient according to the bond strength of formed protuberance of these methods and metal forming, when applying external stress, usually can peel off from metal forming.Therefore, making aspect the metal forming that the surface has protuberance, plating method, etching etc. is difficult to say so to the industrialization advantageous method.
In addition, thus the metal system of making plate object has obtained widely using by the technology of this metal system plate object being carried out press molding by the formed crimping clamping part of the pair of rolls that is in crimped status.As the typical example of this press molding technology, can list the cold rolling etc. of steel.
For example, people have proposed to be formed with on the surface crater (crater) shape recess and along the scheme (for example with reference to patent documentation 1) of the dull roll (dull roller) of the protrusion of the marginal swell of this crater shape recess.Dull roll is to be used between cold rolling process and annealing operation, in surface of cold-rolled steel plate so-called unglazed vestige (dull marks) is set.Thus, be under the situation of intermittently annealing when annealing operation, can prevent the scorification of steel plate.In addition, be under the situation of continuous annealing when annealing operation, can prevent crawling of steel plate when in annealing furnace, transporting steel plate.
In addition, in patent documentation 1, putting down in writing since the protrusion on dull roll surface by brute force by being pressed on the surface of steel plate, thereby flow in the locality plasticity that surface of steel plate produces steel plate materials, so that steel plate materials flows into the recess of dull roll, thereby makes steel plate be able to asperitiesization.Moreover, in patent documentation 1, also putting down in writing in the roller rotation that makes surface smoothing, to the projecting laser pulse of roller surface, make the fusion regularly of roller surface, with the crater shape recess of formation rule, thereby produce dull roll.
Yet patent documentation 1 only discloses and has been used to increase the technology of surface roughness that thickness is the cold-rolled steel sheet of hundreds of microns and even several millimeters, for thickness only tens of microns metal foil surface form the technology of protuberance but without any open.In addition, do not have specific record in the patent documentation 1, thereby can think that dull roll is formed by general material about the dull roll material.So-called general material for example is than the cold-rolled steel sheet steel of hard more.For the dull roll of above-mentioned material, disappear because its surperficial crater shape recess waits because of wearing and tearing easily, thereby be used in can not forming with plant-scale protuberance.In addition, make dull roll, then can't form recess with desirable opening shape if on the roller of above-mentioned material, implement Laser Processing.For example, be the recess of rhombus if desire forms opening shape, then the edge of opening of this recess can be because of the waste heat fusion of laser, thereby becomes ellipse.
In addition, people have also proposed a kind of stack (for example with reference to patent documentation 2), and its surface is formed with concavo-convex, and concave depth is 5～100 μ m, and the total area of protuberance top end surface is 10～80% with respect to the ratio of roller total surface area.Yet the technology in the patent documentation 2 also is to be that the surface of cold-rolled steel plate of hundreds of micron and even several millimeters is provided with unglazed vestige at thickness, rather than is the protuberance that tens of microns metal foil surface forms overshooting shape at thickness.In patent documentation 2, there is not specific record about the stack material, therefore the stack of patent documentation 2 is the same with the dull roll in the patent documentation 1, be used in also can't forming, and can not form recess with desirable opening shape with plant-scale protuberance.
In addition, people have also proposed a kind of calender device (for example with reference to patent documentation 3), and it comprises first working roll and the second level and smooth working roll of side face that is formed with along a plurality of annular recessed portion of circumferentially extending (forming the annular groove of raised line).In the calender device of patent documentation 3, the mode that first working roll and second working roll are parallel to each other with axis is carried out crimping and is formed the crimping clamping part.Make long chi shape metal system plate object by this crimping clamping part, on a surface of the thickness direction of this plate object, form a plurality of projections thus, thereby can obtain the metal plate for producing flat plate.This metal plate for producing flat plate is carried out bending process etc., can obtain flat tube thus.The pipe for flowing of refrigerant that this flat tube can be used as condenser uses.
In patent documentation 3, the material as first working roll discloses carbide alloy.Moreover, the carbide alloy of JIS V10～60 is also disclosed.Yet the technology of patent documentation 3 is not that tens of microns metal forming is a processing object with thickness.In addition, in patent documentation 3, as the formation method of annular recessed portion, the just engraving of concrete record does not carry out any record with regard to Laser Processing.Under the situation for engraving, it is very difficult forming a plurality of recesses with micron unit sizes with the interval about 10～50 μ m.In addition, even if use Laser Processing, form the recess of a plurality of microns units on carbide alloy, it is even that the opening shape of its recess and opening diameter also may not become.Moreover in patent documentation 3, using carbide alloy only only is to be worn for the bottom surface that prevents annular recessed portion.
On the other hand, by Laser Processing before the technology of punching on the electronic components such as pottery system fur sheet material and circuit substrate is (for example with reference to patent documentation 4) well known.That is, utilize laser processing technology usually, form recess on surfaces such as ceramic layer, resin beds.Yet motion or report do not utilize Laser Processing to form hundreds of and even tens million of the technological thoughts with recess of micron unit sizes in the metal surface as yet.And when utilizing Laser Processing to form a plurality of above-mentioned recess in general metal surfaces such as stainless steel, it is inhomogeneous that the opening shape of the recess of this metal surface and opening diameter can become.Moreover its mechanical strength of formed recess, mar proof etc. are lower, exist to cause problems such as wearing and tearing, distortion, breakage easily.
Moreover, be to adopt usually thereby use the ceramic roller on side face, be formed with a plurality of recesses that resin sheet is carried out press molding carries out embossing processing on the resin sheet surface technology.Yet when using the ceramic roller be formed with recess on side face that metal forming is carried out press molding, ceramic roller side face produces a large amount of crackles, damaged, crack etc., thereby can't carry out continuous press molding to metal forming.

The specific embodiment
Roller for machining metal foil of the present invention can be used in for example with the metal forming press molding, with the metal forming (to call " metal forming with protuberance " in the following text) that obtains having on one or two surface of thickness direction protuberance.Specifically, use the device for forming and processing of the metal system roller that comprises roller for machining metal foil of the present invention and surface smoothing.The mode that roller for machining metal foil and metal system roller are parallel to each other with axis is carried out crimping and is formed the crimping clamping part.Metal forming is supplied to the crimping clamping part and makes it pass through this crimping clamping part, thereby the surface that makes desire form protuberance contacts with the side face of roller for machining metal foil, just can obtain having on the surface metal forming of protuberance thus.In addition, during use 2 roller for machining metal foil are carried out crimping, just can obtain two surfaces thus and have the metal forming of protuberance.
The metal forming of using roller for machining metal foil of the present invention to carry out press molding is not particularly limited, and can list Copper Foil, copper alloy foil, tinfoil paper, stainless steel foil, aluminium foil, alloy foil, lead foil, nickel foil, zinc paper tinsel etc.In addition, the metal forming of using roller for machining metal foil of the present invention to carry out press molding preferably has the metal forming of characteristics such as crystal boundary is yielding, annealing temperature is lower.In addition, the thickness of metal forming is not particularly limited, and is preferably 10～100 μ m, more preferably 10～50 μ m.
The metal forming with protuberance of using roller for machining metal foil of the present invention and being obtained by processing such as Copper Foil, copper alloy foils is for example applicable to as the negative electrode collector in the lithium secondary battery.On each protuberance surface of the metal forming that obtains by processing such as Copper Foil, copper alloy foils, form the column that contains negative electrode active material and play a role by vacuum deposition method as negative electrode active material layer with protuberance.At this moment, as negative electrode active material, for example can use silicon, Si oxide, silicon-containing alloy, silicon compound, tin, tin-oxide, Sn-containing alloy, tin compound etc.
Owing to be formed with the negative electrode active material layer of column on the protuberance surface, thereby absorbed, thereby can prevent the distortion of negative electrode collector and even negative pole and negative electrode active material layer peeling off from the negative electrode collector etc. at the stress that expansion and contraction produced that embeds and be accompanied by during the removal lithium embedded ion negative electrode active material.Consequently, it is good and can realize the lithium rechargeable battery of high output to obtain charge and long-time stability etc.
In addition, by the resulting metal forming with protuberance of the present invention also applicable to the metal forming in the flexible printed circuit board for example or metal level, lead frame with metal substrate etc.
Roller for machining metal foil of the present invention has 2 features.The 1st feature is to be formed with a plurality of recesses on its side face.The 2nd feature is that the skin section at least that is formed with recess comprises the metal material with particular characteristics.
Recess is to have opening on the side face (being designated hereinafter simply as " roller side face ") at roller for machining metal foil of the present invention, compares the roller side face to the inner recess of roller or hollow area of space.The bottom surface of recess can be the plane of general planar, also can be dome-shaped.
Each recess is generally forming independently with mode that adjacent other recess is not connected, but the invention is not restricted to this, also can partly be connected to form one, can also all be connected to form one.Preferred each recess forms independently in disconnected mode.
The opening shape of the recess on the roller side face is not particularly limited, but preferably sub-circular, approximate ellipsoidal, approximate rhombus, approximate regular polygon etc.Regular polygon is preferably 3～8 limit shapes, more preferably 4～6 limit shapes.In addition, sub-circular comprises the shape of circle and sub-circular.This situation is equally applicable to other shape.
The opening diameter of the recess on the roller side face is not particularly limited, and is preferably 1 μ m～35 μ m, more preferably 2 μ m～30 μ m.When opening diameter was lower than 1 μ m, the opening diameter that is difficult to make each recess is uniformity roughly.When opening diameter surpassed 35 μ m, being unwell to thickness was the Surface Machining of the metal forming about tens of microns.In addition, when metal forming is carried out press molding, under the effect of additional stress, might produce wearing and tearing and distortion etc. at recess.In addition, be under the situation of sub-circular, approximate ellipsoidal or approximate regular polygon at opening shape, opening diameter is the minimum positive diameter of a circle length of this circle of interior bag, ellipse or regular polygon.Opening shape is under the situation of approximate rhombus, and opening diameter is a catercorner length long in this rhombus diagonal.
Concave depth is not particularly limited, and for example can carry out suitable selection according to the height of the protuberance that forms in the metal foil surface desire etc.Be preferably 0.2～1.5 times of opening diameter, more preferably 0.3～1.2 of opening diameter times.When concave depth is lower than 0.2 times of opening diameter, might form protuberance in metal foil surface with uniform size and shape.In addition, when 1.5 times the mode that surpasses opening diameter with concave depth forms, adopt very difficulty of laser processing method.And adopt the cutting rule expending a large amount of time aspect the recess formation or to come down to impossible.In addition, concave depth is meant and drops to the length of vertical line that hypothesis is present in the roller side face of recess opening part from the darkest place of recess bottom surface depression.
In the formation spacing of roller side face upper recess at the axis direction (length direction) of roller and circumferentially all be not particularly limited.The axis direction spacing of recess can be carried out suitable selection according to design load of the length of the opening diameter of recess, opening shape, roller and the metal forming with protuberance that will obtain etc., be preferably more than the 4 μ m, more preferably 8～30 μ m are preferably 15～30 μ m especially.When the axis direction spacing of recess is lower than 4 μ m, adopts laser processing method to make between the recess easily and interlink.Therefore, the area on the roller surface between recess and the recess that is adjacent becomes extremely small, consequently, under the effect of the stress that is added when metal forming is carried out press molding, the compartment between recess and the recess that is adjacent might deform.In addition, the spacing higher limit on the axis direction can be according to suitable in addition selections such as the length of roller.
In addition, spacing on the circumferencial direction of recess also can be carried out suitable selection according to design load of the circumferential length of the opening diameter of recess, opening shape, roller and the metal forming with protuberance that will obtain etc., but be preferably more than the 4 μ m, more preferably 5～20 μ m.When the spacing of the circumferencial direction of recess is lower than 4 μ m, adopts laser processing method to make between the recess easily and link.Therefore, the area that separates the roller surface of recess becomes extremely small, and under the effect of the stress that is added when metal forming is carried out press molding, the partition between the recess might deform.In addition, the spacing higher limit on the circumferencial direction can be carried out suitable selection according to circumferential length of roller etc.
In this manual, the spacing of axis direction (length direction) is by the distance (length) between 2 parallel lines of the center of 2 adjacent on axis direction recesses and extension along the circumferential direction.Circumferential spacing is by the center of 2 adjacent in a circumferential direction recesses and along the distance (length) between 2 parallel lines of axis direction extension.So-called recess center is meant the center of the opening of recess.The center of so-called opening is meant when opening shape when recess is sub-circular, approximate ellipsoidal or approximate regular polygon the center that the minimum of this circle of interior bag, ellipse or regular polygon is just being justified.In addition, the opening shape when recess is that 2 intersection of diagonal are the center of opening when being similar to rhombus.
The section configuration of the recess on the direction vertical with the side face of roller preferably from the roller side face towards the recess bottom surface, its section width is gradually or the conical in shape of dwindling continuously.Because the recess section is conical in shape, thus by the press molding of metal forming when metal foil surface forms protuberance, can significantly improve the recess of roller side face and the release property of metal forming protuberance, thereby be very difficult to produce the undesirable conditions such as distortion of protuberance.
Recess adopts Laser Processing to form, about the details appearance back explanation of Laser Processing.
The skin section at least that is formed with recess of roller for machining metal foil of the present invention comprises specific metal material.The Rockwell hardness of this metal material is counted HRA81.2～90.0 with the A scale, is preferably HRA83.9～89.0, and bending strength is 3GPa～6GPa, is preferably 3.3GPa～5.5GPa.
When Rockwell hardness is lower than HRA81.2 in the A scale, even metal forming is carried out press molding, also because the flattening of roller, perhaps crooked on direction of principal axis, thereby might not can make the formation of protuberance become insufficient to the sufficient pressure of metal forming transmission, thereby reduce the height of protuberance, perhaps can not be formed uniformly the protuberance that has roughly near the size and shape of design load.Therefore, might can not obtain having the metal forming of desirable protuberance.In addition, roller for machining metal foil surface produces wearing and tearing, thereby is easy to generate the wearing and tearing, distortion etc. of recess.On the other hand, when Rockwell hardness in the A scale during above HRA90.0, be easy to generate crackle, damaged, cracking etc. at the recess of roller for machining metal foil, thereby might cause making the shape of protuberance to deform or form the press molding of inadequate metal forming such as protuberance in unwanted position.
In this manual, Rockwell hardness (HRA) is according to JIS Z-2245, particularly the value that is calculated by following formula.
HRA＝100-0.5h
(in the formula, h represents the difference h of the compression distance of diamond penetrator)
The difference h of the compression distance of diamond penetrator obtains by following method.The radius of curvature of using the top is 120 ° a diamond penetrator as 0.2mm, coning angle, additional initial load 98.07N on specimen surface, additional testing load 588.4N then, additional once more afterwards initial load.The compression distance of diamond penetrator under twice the initial load before and after measuring is with the difference of these measured values difference h as the compression distance of diamond penetrator.
In addition, when bending strength is lower than 3GPa, easily produce cracking, damaged, crackle etc., thereby might cause making the shape of protuberance to deform or form the press molding of inadequate metal forming such as protuberance in unwanted position at the recess of roller for machining metal foil.Therefore, might make roller for machining metal foil can not bear long-term use, and it is insufficient also can to cause protuberance to form at the use initial stage, thereby increases the scrappage of product.On the other hand, when bending strength surpasses 6GPa, even metal forming is carried out press molding, also because the flattening of roller, perhaps crooked on direction of principal axis, thereby might not can make the formation of protuberance become insufficient to the sufficient pressure of metal forming transmission, thus reduce the height of protuberance, perhaps can not be formed uniformly the protuberance that has roughly near the size and shape of design load.In addition, the abrasion resistance properties on roller for machining metal foil surface reduces, and is easy to generate the wearing and tearing, distortion of recess etc.In addition, metal forming is shaped after the processing, and the release property between roller for machining metal foil and the metal forming reduces, and might produce undesirable conditions such as being involved in of the metal forming that caused by roller for machining metal foil.
In this manual, bending strength is according to JIS Z-2248, the value that specifically records by the following method.Sample uses diameter D to be 13mm, the length pole as 300mm.Universal testing machine and its attached bend test device are used in the anti-reflecting bending strength determining test, and length of support is set at 200mm from L, implements 3 bend tests.Load when supposing sample fracture is maximum load W Max, bending strength σ bCalculate by following formula.
σ b＝8W maxL/πD 3
