Then, the method to the peak value emission wavelength of setting above-mentioned upper reaches LED30a, middle reaches LED30b, downstream LED30c describes.
At first, the method to the peak value emission wavelength of setting upper reaches LED30a describes.Fig. 8 representes to set the flow process of the peak value emission wavelength of upper reaches LED30a.The peak value emission wavelength of upper reaches LED30a; Be to be the thickness of water with respect to the solvent in the active material intermixture that is dried at upstream region Ta; Do not make the ultrared wavelength of the scope of this active material intermixture boiling, the ultrared absorptivity that is set to water reaches maximum wavelength.In addition, the active material intermixture does not seethe with excitement and is meant that the water in this active material intermixture does not seethe with excitement.
Specifically; As shown in Figure 9; Derive the first relevant of relation that the expression ultrared wavelength (transverse axis among Fig. 9) that LED30 sent and the ultrared absorptivity (longitudinal axis among Fig. 9) of water are arranged in advance, the thickness derivation (the operation A1 of Fig. 8) that first is correlated with presses the water in the active material intermixture.In addition, the thickness of the thickness of water and active material intermixture self is roughly the same.In addition, in embodiment illustrated, the thickness of water has two kinds of 10 μ m and 2 μ m, but in fact also derive in advance the first relevant of other thickness is arranged.
In addition, shown in figure 10, derive second relevant (the operation A1 of Fig. 8) that the expression ultrared wavelength (transverse axis among Figure 10) that LED30 sent and the relation of the luminous intensity (longitudinal axis among Figure 10) of LED30 are arranged in advance.In addition, in embodiment illustrated, it is the LED of 2.84 μ m～4.45 μ m that expression has ultrared wavelength, is correlated with but in fact also derive in advance to have with respect to second of other wavelength.
And shown in figure 11, the third phase of the relation of the luminous intensity (longitudinal axis among Figure 11) of the LED30 when derivation in advance has the thickness (transverse axis among Figure 11) of the water in the expression active material intermixture to come to life with the active material intermixture closes (the operation A1 of Fig. 8).In addition, in Figure 11, third phase close above be that the luminous intensity of LED30 is higher than under the situation of the luminous intensity that third phase closes the boiling of active material intermixture.On the other hand, in Figure 11, third phase close below be that the luminous intensity of LED30 is lower than under the situation of the luminous intensity that third phase closes, the active material intermixture does not seethe with excitement.
And, infer the thickness (the operation A2 of Fig. 8) of the water in the active material intermixture that upstream region Ta is dried.In this execution mode, the thickness of this water for example is estimated to be 10 μ m.
Then, be based on the thickness of the water that operation A2 infers, use the first relevant ultrared wavelength corresponding (below, be also referred to as " peak wavelength ") (the operation A3 of Fig. 8) of deriving with the ultrared maximum absorbance of water.In this execution mode, be 3 μ m with the corresponding peak wavelength of thickness 10 μ m of water.
Then, be based on the peak wavelength that operation A3 infers, use the maximum emission intensity (the operation A4 of Fig. 8) of the second relevant upper reaches LED30a of derivation.In this execution mode, the maximum emission intensity of the upper reaches LED30a corresponding with peak wavelength 3 μ m is 1.0.
Then, be based on the maximum emission intensity of thickness with the upper reaches LED30a that derives at operation A4 of the water that operation A2 infers, use third phase to close to judge active material intermixture whether seethe with excitement (the operation A5 of Fig. 8).
Then, when active material intermixture in operation A5 is judged as when not seething with excitement, the peak value emission wavelength of upper reaches LED30a is set to the peak wavelength (the operation A6 of Fig. 8) of in operation A4, deriving.That is, in the LED30a of the upper reaches, use the peak wavelength of in operation A4, deriving LED as emission wavelength.On the other hand, when active material intermixture in operation A5 is judged as boiling, be back to above-mentioned operation A3, carry out operation A3～operation A5.Then, until active material intermixture in operation A5 be judged as do not seethe with excitement till, repeat these operations A3～operation A5.
In this execution mode, in operation A5, the thickness 10 μ m of relative water, the luminous intensity that third phase closes is 0.6.To this, the maximum emission intensity of the upper reaches LED30a that in operation A4, derives is 1.0.Therefore, active material intermixture boiling.
Like this, in this execution mode, the active material intermixture is judged as boiling in operation A5, therefore, is back to operation A3.In operation A3, use the first relevant derivation peak wavelength corresponding with the absorptivity that is only second to maximum absorbance.In this execution mode, peak wavelength is 6 μ m.Then, in operation A4, use the second relevant maximum emission intensity 0.5 that derives the upper reaches LED30a corresponding with peak wavelength 6 μ m.Then, in operation A5, use third phase to close and judge whether the active material intermixture seethes with excitement.In this execution mode, the maximum emission intensity of upper reaches LED30a is 0.5, and the active material intermixture does not seethe with excitement.
Like this, when active material intermixture in operation A5 is judged as when not seething with excitement, the peak value emission wavelength of upper reaches LED30a is set at the peak wavelength (the operation A6 of Fig. 8) of in operation A4, deriving.In this execution mode, the peak value emission wavelength of upper reaches LED30a is set at 6 μ m.That is, LED30a use peak value emission wavelength is the LED of 6 μ m at the upper reaches.
For the peak value emission wavelength of middle reaches LED30b and downstream LED30c, carry out above-mentioned operation A1～A6 too and set.Then, in this execution mode, the peak value emission wavelength of downstream LED30c is set at 3 μ m.In addition, the peak value emission wavelength of middle reaches LED30b is greater than the peak value emission wavelength of 3 μ m less thaies, 6 μ m, for example is set at 4.5 μ m.
The electrode manufacturing apparatus 1 that relates to this execution mode is made up of above mode.The processing of then, being used to of being carried out by this electrode manufacturing apparatus 1 being made electrode E describes.
Metal forming M unreels from let off roll 10, and is arrived coating portion 11 by conveyance.In coating portion 11,, apply from a slimy active material intermixture S who applies 20 to the surface of the metal forming M in the conveyance.At this moment, through supplying with active material intermixture S from the coating of the both sides that are configured in metal forming M 20,20, the thickness on the two sides of metal forming M with equalization applies active material intermixture S simultaneously.In addition, will be coated in the central portion of the short side direction of metal forming M from the active material intermixture S of coating 20 supply.And through supplying with active material intermixture S intermittently from applying 20, a plurality of zones on the long side direction of metal forming M apply active material intermixture S.
Then, the metal forming M that is coated with active material intermixture S is arrived drying section 12 by conveyance.At drying section 12, the radiation heating that places the infrared ray of a plurality of LED30 and a plurality of reflecting plate 40 of the both sides of metal forming M to produce through the origin autogamy makes the active material intermixture S on two sides of metal forming M dry.At this moment, the peak value emission wavelength of upper reaches LED30a is 6 μ m as stated, and the peak value emission wavelength of middle reaches LED30b is 4.5 μ m, and the peak value emission wavelength of downstream LED30c is 3 μ m.And, the active material intermixture S ground that do not seethe with excitement, active material intermixture S absorbs infrared ray to greatest extent, and active material intermixture S is dried in above-mentioned LED30 successively.
In addition, at drying section 12,, make the active material intermixture S drying on the two sides of metal forming M through the Convective Heating that the air of being supplied with by the arid region D that forms to the both sides at metal forming M from air supply opening 41, D produces.And, through in the D of arid region, produce from the air-flow of air supply opening 41 to the end of arid region D, flow smoothly to arid region D from the water of active material intermixture S evaporation, and the water of this evaporation is not removed with can not being attached to metal forming M again.The active material intermixture S on the two sides of metal forming M is dried in this wise, forms the active material layer F of the thickness of regulation on the two sides of this metal forming M.
After this, form the metal forming M of active material layer F, arrived takers-in 13, and batch at this takers-in 13 by conveyance.The a series of processing of electrode manufacturing apparatus 1 finishes in this wise, and electrode E is made.
Adopt above mode; Drying section 12 is split into 3 regional Ta, Tb, Tc; And the peak value emission wavelength of the LED30 of regional Ta, Tb, Tc is set at the wavelength of the scope that does not make active material intermixture S boiling; Therefore can be as prior art the surface of the active material layer of ground on metal forming form concavo-convexly, can have the active material layer F on level and smooth surface with the thickness formation of equalization.In addition, also do not peel off in the generation of the border of metal forming M and active material layer F.And the peak value emission wavelength of the LED30 of regional Ta, Tb, Tc is set at the ultrared absorptivity that makes water and reaches maximum wavelength, therefore can heat active material intermixture S efficiently and make its drying.And be set in each regional Ta, Tb, Tc of the emission wavelength of such LED30 carry out, and therefore compared with prior art can shorten the drying time of active material intermixture S more, also can shorten the length of drying section 12.As stated according to this execution mode, can suitably and efficiently form active material layer F on the surface of the metal forming M of band shape.
In addition, at drying section 12,, make the active material intermixture S on the metal forming M dry through radiation heating that produces by infrared ray and the Convective Heating that produces by the air of in the D of arid region, supplying with from air supply opening 41 from a plurality of LED30 and reflecting plate 40.Because use radiation heating that produces by infrared ray and the such 2 kinds of drying means of Convective Heating that produce by air in this wise, can suitably make this active material intermixture S dry.And, under the situation of having used the radiation heating that produces by infrared ray, do not exist with ... the ultrared radiant heat of distance ground conduction between LED30 and reflecting plate 40 and the metal forming M.Therefore, can suitably do not heated active material intermixture S by the bending of metal forming M and obliquity effects ground.
In addition, at drying section 12, can make in the D of arid region to produce from the air-flow of air supply opening 41 to the end of arid region D.Through this air-flow, when active material intermixture S on making metal film M was dry, discharged the end of the water of evaporation D from the arid region, water that therefore should evaporation can be not again attached to the surface of metal forming M.Therefore, can more suitably make the active material intermixture S on the metal forming M dry.
In addition, reflecting plate 40 clips the surface configuration relatively of LED30 and metal forming M, therefore is radiated the infrared ray of the opposition side of metal forming M from LED30, is radiated metal forming M in reflecting plate 40 reflections.Therefore, can utilize whole infrared rays, can make the active material intermixture S on the metal forming M dry efficiently.
In addition, in coating portion 11, the long side direction of metal forming M be horizontal direction towards conveyance metal forming M, therefore can not flow to the upstream side or the downstream of the conveyance direction of this metal forming M at the active material intermixture S of the surface applied of metal forming M.And, the short side direction of metal forming M be vertical direction towards conveyance metal forming M, therefore can apply active material intermixture S equably on the two sides of metal forming M.Active material intermixture S can be suitably applied in coating portion 11 like this, therefore active material layer F can be on metal forming M, suitably formed.
In addition, between let off roll 10 and takers-in 13, long side direction be horizontal direction towards conveyance metal forming M, therefore can metal forming M be reduced to certain height, make the maintenance of electrode manufacturing apparatus 1 become easy.Therefore, can form active material layer F on the surface of metal forming M effectively.
