Changing into handling part 511,512,513,514 in any; All changing into liquid reservoir 55; Dispose in that (direction that the moving direction (directions X) of F1～F3) intersects is (in this example with aluminium foil F; The Y direction of quadrature) relative a plurality of electrodes 53, aluminium foil F pass through between the electrode respect to one another 53 from a plurality of electrodes 53 singly.In this example, have 4 electrodes 531,532,533,534 as electrode 53, the electrode 531,534 that is positioned at both sides is maintained on the pair of sidewalls part 553 that changes into liquid reservoir 55.Therefore, (the aluminium foil F1 among the F1～F3) is from electrode 531, pass through between 532, and aluminium foil F2 is from electrode 532, pass through between 533, and aluminium foil F3 is from electrode 533, pass through between 534 for 3 aluminium foil F.
(F1～F3) compares with electrode 53 (electrode 531,532,533,534) and is set as high potential aluminium foil F.Particularly, (F1～F3) applies earthed voltage, electrode 53 (electrode 531,532,533,534) is applied the structure of negative potential adopt to utilize 69 couples of aluminium foil F of power supply roller.Perhaps, (F1～F3) applies positive voltage, electrode 53 (electrode 531,532,533,534) is applied the structure of earthing potential adopt to utilize 69 couples of aluminium foil F of power supply roller.Therefore, any one two sides of 3 aluminium foil F is all become by dc electrolysis (anodic oxidation) and changes into paper tinsel Ff, on such two sides that changes into paper tinsel Ff, is formed with dielectric layer (aluminium oxide).
(reeling end 70)
With reference to Fig. 1 and Fig. 4 (b) when explaining, be that aluminium foil F (3 takers-in Q (Q1, Q2, Q3) of F1～F3) are batched in the center rotation Yi Bian reeling end 70 disposes on one side shown in arrow Q α with the axis L b that extends at above-below direction.Takers-in Q1, Q2, Q3 and outlet roller R1, R2, R3 have man-to-man relation, takers-in Q1, Q2, Q3 batch respectively with their Width towards above-below direction (Z direction) and the mobile down aluminium foil F (F1, F2, F3) of state arranged side by side each other.Particularly, takers-in Q1 batches the aluminium foil F1 that sees off from outlet roller R1, and takers-in Q2 batches the aluminium foil F2 that sees off from outlet roller R2, and takers-in Q3 batches the aluminium foil F3 that sees off from outlet roller R3.
(handling action)
In aluminium foil apparatus for continous treatment 100, (F1～F3) sees off from workpiece unloading part 20 under the state arranged side by side each other towards above-below direction (Z direction) at the Width that makes them as foil, etched not along its length continuously with the aluminium foil F of a plurality of strips.In addition; Make a plurality of aluminium foil F of having seen off (F1～F3) keep its Width towards above-below direction (Z direction) and state arranged side by side each other on one side from etching solution L3, detergent remover L4 with change into and pass through continuously the liquid L5, carry out etch processes on one side, clean processing and change into processing.Its result, at reeling end 70, keep its Width towards the state of above-below direction (Z direction) with 3 aluminium foil F (F1～F3) batch as changing into paper tinsel Ff respectively.
(action effect)
As described above, in aluminium foil apparatus for continous treatment 100, can be through aluminium foil F not being turned back at the above-below direction several times with the roller of flat-hand position configuration.Therefore, even under the situation that aluminium foil F cuts off, make aluminium foil F once more in treatment fluid through not needing the too many time yet.
In addition, aluminium foil F is owing to make its Width towards above-below direction, therefore when coming in and going out treatment fluid, need not turn back at above-below direction through roller etc., can the number of turns of aluminium foil F be suppressed at Min..The quality that causes because of turning back that therefore can suppress aluminium foil F descends.For example, when carrying out continuous etching, can prevent at the no electrolytic etching state of part generation of turning back, so can improve the etching multiplying power based on roller in etch processes portion 30.In addition,, can prevent, crack changing on the film (anode oxide film) in the part of turning back based on roller changing into handling part 50 when changing into continuously.In addition, because the number of turns of aluminium foil F is less, therefore,, can not apply excessive power to aluminium foil F even use as aluminium foil F under the situation of aluminium foil of 150 μ m～200 μ m thickness yet.Therefore, even the situation of the thick aluminium foil F of 150 μ m～200 μ m degree can not produce the paper tinsel fracture yet.
At this, to compare with the situation that aluminium foil F is turned back through roller at the above-below direction several times with flat-hand position configuration, the length that impregnated in the aluminium foil F in the treatment fluid (etching solution L3, detergent remover L4, change into liquid L5) simultaneously shortens.But, because handle a plurality of aluminium foil F simultaneously, so can avoid the remarkable decline of productivity.
In addition, in treatment fluid reservoir (etching solution reservoir 35, detergent remover reservoir 45, change into liquid reservoir 55), aluminium foil F gets into from going into latasuture crack (going into latasuture crack 351s, 451s, 551s), comes out from going out latasuture crack (going out latasuture crack 352s, 452s, 552s).Therefore, make Width towards above-below direction when making aluminium foil F move and handle, the position generation seepage that treatment fluid gets into the treatment fluid reservoir from aluminium foil F position and aluminium foil F leave the treatment fluid reservoir.But, because the position that the position of aluminium foil F entering treatment fluid reservoir and aluminium foil F leave the treatment fluid reservoir is slot-shaped, so can the seepage of treatment fluid be suppressed at less.
In addition; Owing to be provided with treatment fluid feedway from treatment fluid to treatment fluid reservoir (etching solution reservoir 35, detergent remover reservoir 45, change into liquid reservoir 55) that supply with; Therefore can treatment fluid be replenished to the treatment fluid feedway only with amount from treatment fluid reservoir seepage treatment fluid partly.Therefore, can the liquid level of treatment fluid be maintained assigned position.In addition, owing to have treatment fluid retracting device (etching solution retracting device 37, detergent remover retracting device 47, change into liquid retracting device 57), therefore can prevent the waste of treatment fluid.In addition; Make the treatment fluid that reclaims by the treatment fluid retracting device be back to the treatment fluid return flow path (etching solution return flow path 39, detergent remover return flow path 49, change into liquid return flow path 59) of treatment fluid reservoir because have, turn back to the treatment fluid reservoir so can make from the treatment fluid of treatment fluid reservoir seepage.The waste of the treatment fluid in the time of therefore, can liquid level that keep treatment fluid being in assigned position is suppressed at less.
In addition; Unloading part 20 has the outlet roller R that places vertically that a plurality of one side see aluminium foil F off around central axis rotation one side that above-below direction extends, Yi Bian reeling end 70 has the takers-in Q that places vertically that aluminium foil F is batched in the central axis rotation of extending around above-below direction on a plurality of one side.Therefore, even, also can carry out seeing off of aluminium foil F and batching of aluminium foil F effectively in that Width is made under the situation that aluminium foil F moves and handle towards above-below direction.
In aluminium foil apparatus for continous treatment 100; Mobile route along aluminium foil F is provided with a plurality of treatment fluid reservoir; The treatment fluid reservoir of the part in a plurality of treatment fluid reservoir (etching solution reservoir 35); Each of a plurality of aluminium foil F is carried out alternating current electrolysis,, each of a plurality of aluminium foil F is carried out dc electrolysis in the treatment fluid reservoir (changing into liquid reservoir 55) of another part.Therefore, can carry out alternating current electrolysis and dc electrolysis through an aluminium foil apparatus for continous treatment 100 to aluminium foil F.
