Embodiment 1
[0085] Embodiment 1: A copper foil thickness uniformity processing equipment 2, comprising: a copper foil thickness measuring device 2-1, a first treatment tank 2-2, and a second treatment tank 2-3 according to the advancing direction of the copper foil;
[0086] The copper foil thickness measuring device 2-1 includes several laser online thickness gauges 2-2-1 arranged along the width of the copper foil;
[0087] The copper foil is divided into N parts along the width (preferably, the copper foil is equally divided into N parts); a laser online thickness gauge 2-2-1 is set in the middle of each part (it needs to be explained Yes, the above division is only for convenience of explanation: the position of the online thickness gauge 2-2-1 is not to cut the copper foil into N parts, that is, the processed copper foil is still a whole in width);
[0088] The first treatment tank 2-2 includes: the first treatment tank body 2-2-1, the first anode plate assembly 2-2-2, the second ano...
Embodiment 2
[0128] Example 2, such as Figure 8 As shown, the first treatment tank is provided with 2 first anode plate assemblies and 2 second anode plate assemblies; the second treatment tank is provided with 2 third anode plate assemblies and 2 fourth anode plate assemblies.
Embodiment 3
[0129] Embodiment 3, the copper foil of Embodiment 1 is divided into N parts, which are processed separately. Specifically, it is processed according to odd-even numbers.
[0130] N parts of the width of the copper foil, the width of each part is less than 33mm.
[0131] The scheme of embodiment 3 is: y treatment tanks are set, and the metal plates in the y treatment tanks correspond respectively: yk+1, yk+2, yk+3...yk+y; (k=0,1...) .
[0132] For example: the first treatment tank processes the part whose sequence in the width direction of the copper foil is: yk+1;
[0133] The second treatment tank processes the part whose sequence in the width direction of the copper foil is: yk+2;
[0134] ...
[0135] The y-th treatment tank processes the part whose sequence in the width direction of the copper foil is: yk+y.
[0136] When y=3, 3 treatment slots are set;
[0137] The first treatment tank processes the copper foil width direction sequence: 1, 4, 7... (the sequence can...

Abstract
The invention discloses copper foil thickness uniformity treatment equipment, an aftertreatment production line and a raw foil-aftertreatment integrator, and belongs to the technical field of production of electrolytic copper foil. The equipment is characterized by comprising, in the forward direction of copper foil, a copper foil thickness measurement device, a first treatment tank, and a secondtreatment tank, wherein the copper foil thickness measurement device comprises N laser online thickness gauges which are set along the breadth of the copper foil, and anode plate assemblies of the first treatment tank and the second treatment tank both adopt a mode of alternate arrangement of "metal plates & insulating plates". Each metal plate can adopt independent current density, thereby thickening the two sides of the copper foil. By means of the copper foil thickness uniformity treatment equipment, aftertreatment production line and raw foil-aftertreatment integrator, high-quality copperfoil with uniform thickness can be provided, and the requirements of clients for high-performance lithium-battery copper foil are met.
Description
technical field [0001] The invention relates to the field of electrolytic copper foil production, and more specifically relates to a copper foil thickness uniformity treatment equipment, a post-processing production line, and a raw foil-post-processing combined machine. Background technique [0002] "DB-44-T-837-2010 Electrolytic Copper Foil for Lithium-ion Batteries" requires that the uneven thickness of copper foil should not exceed 2%, which is mainly based on the requirements of coating negative active materials and normal charging and discharging of lithium batteries. consider. [0003] Existing research routes start from the raw foil process of copper foil to improve the non-uniformity of copper foil thickness. Through the raw foil process, the thickness unevenness of copper foil can be controlled at about 2%-5%. [0004] However, as lithium battery customers have higher and higher requirements for the quality of delivered copper foil (some customers require: the une...
