Technical Field

The invention mainly relates to the electrolytic copper foil production technology, in particular to a method for calculating the polar distance between a cathode roller and an anode tank and a method for adjusting the polar distance between the cathode roller and the anode tank.

Background

The groove pressure is one of the key factors affecting the quality of the copper foil and the production electricity quantity.

However, in the prior art, there is no method how to evaluate the calculation of the cathode roll and the anode tank.

The solution is obtained by the following formula:

wherein R is_{Anode tank}Is the radius of the anode channel, R_{Cathode roll}Is the radius of the cathode roller, theta is the corresponding corner of the anode groove; h is_y，h_xIs a parameter;

secondly, then the cathode roll is lifted and moved upwards h_y-x。

(1) the basic idea of the application is as follows: a method for calculating the polar distance between a cathode roller and an anode tank is provided, and the method comprises the following steps:

that is, only the distance that the cathode roller moves upward (downward movement may be, or h takes a negative value) needs to be known, that is, the new pole pitch can be known.

(2) Another idea of the present application is to address the following problems: pole pitch is from d_xIs adjusted to d_yHow does the cathode roll move?

When the polar distance is from d_xIs adjusted to d_yWhile the cathode roll distance is moved up h_y-xThe distance is solved by:

the above equation hy, hx has no explicit solution, which can be solved by the Matlab program.

The cathode roll is moved upward manually (by inserting a spacer between the central rotating shaft of the cathode roll and the support portion, or by a mechanical control method such as "a production process for removing white spots by electrolytic copper foil, a foil forming machine, a pole pitch control method" filed by the applicant on the same day).

Drawings

The invention will be further described in detail with reference to examples of embodiments shown in the drawings to which, however, the invention is not restricted.

FIG. 2 is a diagram of a calculation example of example 1.

Detailed Description

Example 1 method for adjusting the polar distance between a cathode roll and an anode cell, the radius of the cathode roll was R_{Cathode roll}The radius of the anode groove is represented by R_{Anode tank}The distance of upward movement of the cathode roll is represented by h, the corresponding rotation angle of the two anode grooves is represented by theta, and the bottom opening of the anode groove is represented by k.

In the initial state (when the device is installed), the anode groove and the cathode roller are concentric, and the polar distance d is equal to R_{Anode tank}-R_{Cathode roll}。

After the cathode roller moves upwards for h, the polar distances between each point of the anode tank and the front part of the cathode roller are different, and when evaluating the tank pressure, the average polar distance d can be adopted₁To calculate the average pole distance d₁Is calculated as follows:

in use, the groove pressure is often low (less than 3.5V), and the probability of occurrence of white spots in the copper foil is high, and in order to avoid the problem of white spots, the groove pressure is generally increased to 5V or more. And the pole pitch is increased, so is the groove pressure. Therefore, the slot pressure is often increased by increasing the pole pitch.

Two comparative example diagrams are given in fig. 2:

the parameters are as follows: r_{Cathode roll}＝750mm，R_{Anode tank}＝760mm，k＝100mm；θ＝180°、150°。

The above-mentioned embodiments are only for convenience of description, and are not intended to limit the present invention in any way, and those skilled in the art will understand that the technical features of the present invention can be modified or changed by other equivalent embodiments without departing from the scope of the present invention.
