With reference to Fig. 2, the adjustment portion 4 may include measuring mechanism 42.
The measuring mechanism 42, for measure it is from the copper foil of 11 uncoiling of the negative pole part, with the width direction (X-axis
Direction) on the basis of thickness distribution.When the measuring mechanism 42 to copper foil on the basis of the width direction (X-direction)
When thickness distribution measures, the regulating mechanism 41 can individually convey each transfer member 31 to the supply department 2
The flow of electrolyte be adjusted, thus, it is possible to the thickness distribution of the copper foil measured by the measuring mechanism 42, from
And the flow of electrolyte is adjusted according to each feed region 17.
Therefore, the electrolytic copper foil manufacturing device 10 of the utility model can make the measuring mechanism 42 and the adjusting machine
It interacts between structure 41, and can be more accurate and accurately adjusts 11 carried out electrodeposit of the negative pole part
The thickness of copper foil.Therefore, the electrolytic copper foil manufacturing device 10 of the utility model can further decrease the width side of copper foil
Thickness deviation in (X-direction), therefore the quality and yield rate of copper foil can not only be further increased, and can be into one
Step improves the quality and yield rate using the secondary cell manufactured by copper foil.
Hereinafter, illustrating the interaction between the measuring mechanism 42 and the regulating mechanism 41, and adjust copper
The process of foil thickness.
First, the measuring mechanism 42 can to the copper foil from 11 uncoiling of the negative pole part, with the width direction (X
Axis direction) on the basis of thickness distribution measure.In this case, the measuring mechanism 42 can be in copper foil from the cathode
The thickness distribution of copper foil is measured immediately after 11 uncoiling of portion.The measuring mechanism 42 can also be in copper foil from the negative pole part
After 11 uncoilings and after the dry liquid of residual dried, the thickness distribution of copper foil is measured.
Later, the regulating mechanism 41 is according to the thickness distribution on the basis of the width direction (X-direction), Neng Goudan
Solely the flow of the electrolyte to being conveyed from the transfer member 31 controls.For example, when the measuring mechanism 42 measures
When some of copper foil is partially larger than root thickness, the regulating mechanism 41 can be reduced via corresponding with some part of copper foil
The transfer member 31 and convey electrolyte flow.Opposite to thatly, when the measuring mechanism 42 measures copper foil
When some part is less than root thickness, the regulating mechanism 41 can increase via corresponding with some part of copper foil described
The flow of transfer member 31 and the electrolyte of conveying.In this case, root thickness was used as in manufacturing copper foil institute's phase during
The copper thickness of prestige can be preset before copper foil manufacturing operation by operating personnel.
Secondly, the electrolyte of the supply department 2 is transported to via the transfer member 31, it can be with the regulating mechanism 41
The flow adjusted is supplied to the feed region 17.
Then, the negative pole part 11 can be such that copper foil is electrolysed heavy using the electrolyte supplied to the feed region 17
It forms sediment.Therefore, when the flow for the electrolyte supplied to some feed region 17 is reduced, in the negative pole part 11 with the supply
The thickness of the copper foil of the carried out electrodeposit in the adjacent part in region 17 may be reduced.When what is supplied to some feed region 17
When the flow of electrolyte increases, the copper of the carried out electrodeposit in the part adjacent with the feed region 17 in the negative pole part 11
The thickness of foil may increase.
The adjustment portion 4 may include multiple measuring mechanisms 42.
The measuring mechanism 42 is directed to the copper foil from 11 uncoiling of the negative pole part, according to along width direction (the X-axis side
To) configuration measured zone it is (not shown) measure copper foil thickness, so as to measure copper foil with the width direction (X-axis
Direction) on the basis of thickness distribution.In this case, the measured zone is equivalent to a measuring mechanism 42 in the width side
The imaginary area included by the range of copper thickness can be measured in (X-direction).For example, including M in the adjustment portion 4
In the case of the measuring mechanism 42, the measuring mechanism 42 divides the copper foil in the width direction (X-direction)
For M measured zones, and the thickness of copper foil is measured according to each measured zone.
Therefore, the electrolytic copper foil manufacturing device 10 of the utility model is measured by reducing a measuring mechanism 42
The measured zone size, come can further increase measure copper thickness measurement operation accuracy and precision.
The measuring mechanism 42 is configurable between the negative pole part 11 and the reeling end 15.In copper foil from the cathode
During the trucking department 13, the cutting part 14 and the reeling end 15 being transported to after 11 uncoiling of portion, the measurement
Mechanism 42 can be continuously to the thickness across the part of the measured zone set of copper foil.In this case, the measurement
Mechanism 42 can configure in a manner of from the spaced-apart interval for making copper foil electrodeposit in the negative pole part 11.
Therefore, the electrolytic copper foil manufacturing device 10 of the utility model is implemented in the measuring mechanism 42 for measuring copper foil thickness
During the measurement operation of degree, the interference degrees between the measuring mechanism 42 and the negative pole part 11 can be reduced.Therefore,
The electrolytic copper foil manufacturing device 10 of the utility model can improve the measurement for measuring copper thickness of the measuring mechanism 42
The easiness of operation.In addition, in the electrolytic copper foil manufacturing device 10 of the utility model, the measuring mechanism 42 can be in copper foil
The thickness of copper foil is measured after at the time of terminating electrodeposit.Therefore, the electrolytic copper foil manufacturing device 10 of the utility model can
Further increase the accuracy of the measurement operation for measuring copper thickness of the measuring mechanism 42.
The utility model illustrated above is not limited to embodiment and attached drawing as described above, for the utility model
The those of ordinary skill of affiliated technical area it should be clear that the technical concept without departing from the utility model scope
It is interior, various replacements, deformation and change can be carried out.
