The direction in which the slide substrate 2 moves along the guide rail is perpendicular to the axial direction of the central rotating shaft of the cathode roller and is horizontal.
The sliding base plate 2 can be driven by an air rod 3, the air rod 3 is parallel to the guide rail, and the movable end of the air rod is fixedly connected with the end face of the sliding base plate 2.

The distance between the vertical guide wheel 1 and the cathode roller in the horizontal direction is adjusted through data fed back by the electrolyte height sensor.
For "the distance in the horizontal direction between the vertical guide wheel 1 and the cathode roll is adjusted by the data fed back by the electrolyte level sensor", the adjustment is as follows:

S3-3-3，x0+assigning x to x0。
Need to explainIs that x0、y1The adjustment of (a) is of the mm order and therefore its sensitivity needs to be analyzed.
Second, sensitivity analysis
Firstly, taking the radius of a cathode roller as 750mm (namely the cathode roller with the diameter of 1.5 m) as an example, the radius of a vertical guide wheel is 100 mm;
as shown in fig. 3, in the initial state, x0 is 900mm, and y0 is 80mm, 120mm, 160mm, 200mm, 300mm, 400mm, 6 cases are selected.
FIG. 3 depicts the variation of y1 for the distance X the vertical guide wheels move toward the cathode roller (the X-axis is positive for the direction the cathode roller points toward the vertical guide wheels, so the X-axis of FIG. 2 is negative); i.e. x on the abscissa and y on the ordinate1' (i.e., dy)1/dx)
Secondly, taking the radius of the cathode roller as 1150mm (namely the cathode roller with the diameter of 2.3 m) as an example, the radius of the vertical guide wheel is 100 mm; as shown in fig. 4, 6 cases of y0 being 80mm, 120mm, 160mm, 200mm, 300mm, 400mm were selected. In the initial state, x0 is 1300 mm.
FIG. 4 depicts the variation of y1 for the distance X the vertical guide wheels move toward the cathode roller (the X-axis is positive for the direction the cathode roller points toward the vertical guide wheels, so the X-axis of FIG. 4 is negative); i.e. x on the abscissa and y on the ordinate1' (i.e., dy)1/dx)
Thirdly, taking the radius of the cathode roller as 1350mm (namely the cathode roller with the diameter of 2.7 m) as an example, the radius of the vertical guide wheel is 100 mm; as shown in fig. 5, 6 cases of y0 being 80mm, 120mm, 160mm, 200mm, 300mm, 400mm were selected. In the initial state, x0 is 1500 mm.
FIG. 5 depicts the variation of y1 for the distance X the vertical guide wheels move toward the cathode roller (the X-axis is positive for the direction the cathode roller points toward the vertical guide wheels, so the X-axis of FIG. 5 is negative); i.e. x on the abscissa and y on the ordinate1' (i.e., dy)1/dx)
From the above three cases, y0The smaller，dy1The smaller the/dx，That is, the lower the sensitivity; while the lower the sensitivityThe more convenient the mechanical control (e.g. y)1The 2mm movement is needed, and the corresponding two schemes of x being 0.8mm and x being 1mm are needed, and the scheme of x being 1mm is certainly more convenient for accurate control).
X in FIGS. 3, 4 and 50The selection of (A) is set according to the actual situation (the value of y1 is between 350mm and 100 mm).
Starting from sensitivity control, y0It is preferable to take 200mm or more.
However, the vertical guide wheels are positioned too high, and the length of the O-ring from the cathode roll to the vertical guide wheels may cause crystallization problems (not only the O-ring is crystallized in the present application, but also the vertical guide wheels that are allowed to contact).
This is also one reason why the vertical guide wheels in previous production lines could not be set too high.
Thirdly, treatment of crystallization problem
According to the results obtained in stage two, y0 is 200mm or more. Therefore, the O-ring has a long time above the plane of the central axis of the cathode roll and has a certain distance from the cathode roll in the X direction.
The above also provides space for setting up the crystallization process.
One convenient way is to provide the cleaning roller 6, as shown in fig. 2 and 6, to provide absorbent cotton on the surface of the cleaning roller 6, that is, to absorb the electrolyte on the lower surface of the cleaning roller into the absorbent cotton when the O-ring contacts the vertical guide wheel. This scheme is also used in practice.
In the simple mode, the timing needs to be adjusted manually.
In order to solve the problems, an improved scheme is provided:
as shown in fig. 7:
an O-ring crystallization preventing device 7 is provided on the slide base plate 2.
The O-ring crystallization prevention apparatus 7 includes: a roller 7-1 with a notch, a wind-up roller 7-2 and a wind-up roller 7-3;
the roller with the notch 7-1 is characterized in that the corresponding phase angle of the notch is 42-20 degrees;
the notch corresponds to the O-shaped ring;
the unwinding roller 7-3 is wound with linear absorbent cotton (the linear absorbent cotton is made by the prior art, for example, 201811054700.3), and the linear absorbent cotton passes through a horizontal notch after coming out of the unwinding roller 7-3 and then is wound on the winding roller 7-2.
Further, the cross section of the notch is arc-shaped.
The special design is that: the cross section of the linear absorbent cotton is in a round shape (good elasticity in the radial direction and the length direction), when the linear absorbent cotton passes through the notch, a part of the cross section of the linear absorbent cotton is arranged on the outer side of the roller 7-1, so that when the inclination angle of the O-shaped ring changes, the roller 7-1 can be applied without rotating (the size of a phase angle corresponding to the notch is 42-20 degrees, the linear absorbent cotton passes through the horizontal notch, the cross section of the linear absorbent cotton is in a round shape, and the common effect of the characteristics is that when the inclination angle of the O-shaped ring changes in a range of 70-85 degrees, the roller 7-1 does not need to rotate, and the linear absorbent cotton can be always contacted with the O-shaped ring).
The special design also includes: the X-direction moving base plate 7-4 and the X-direction moving power mechanism 7-5, wherein the X-direction moving power mechanism 7-5 is used for driving the X-direction moving base plate 7-4 to move in the X direction; the X-direction moving substrate 7-4 and the X-direction moving power mechanism 7-5 are both arranged on the upper surface of the sliding substrate 2.
The X-direction moving power mechanism 7-5 adopts the prior art, for example: screw-nut design, gas lever design.
The roller 7-1, the wind-up roller 7-2 and the unreeling roller 7-3 are all fixedly arranged on the sliding substrate 2 through a rack.
The radius of the roller 7-1 is rRollerThe coordinates of the central axis are: x is the number ofRoller，yRoller(ii) a The section radius of the linear absorbent cotton is r under the condition of no stressCotton；
Then:
xroller＝(yRoller-E)/C
E and C are both parameters and are calculated using the following formula:
C＝(b-y1)/(a-x1)
E＝b-C·a-(C2+1)0.5r’
x1＝{R2a+Rb[(a2+b2-R2)0.5]}/(a2+b2)
y1＝{R2b-Ra[(a2+b2-R2)0.5]}/(a2+b2)
a＝x0R/(R+r)
b＝y0R/(R+r)
r' is in (r)Roller～rRoller+rCotton) In the meantime.
It should be noted that, in the following description,
knowing xRollerThe moving distance of the X-direction moving substrate 7-4 can be controlled.
The scheme of example 1 is further optimized as follows:
for "adjusting the distance in the horizontal direction between the vertical guide wheel 1 and the cathode roll and simultaneously adjusting the distance in the horizontal direction between the roll 7-1 and the cathode roll by the data fed back by the electrolyte level sensor", the adjustment is as follows:
s3-2-4, the distance X' that the X-direction moving substrate 7-4 moves on the sliding substrate 2 is as follows:
first, according to newly assigned x of S3-2-30And solving the X-axis target coordinate range of the central axis of the roller 7-1 as follows: x is the number ofRoller target 1、xRoller target 2
Solving for xRoller target 1
a＝x0R/(R+r)
b＝y0R/(R+r)
x1＝{R2a+Rb[(a2+b2-R2)0.5]}/(a2+b2)
y1＝{R2b-Ra[(a2+b2-R2)0.5]}/(a2+b2)
C＝(b-y1)/(a-x1)
E＝b-C·a-(C2+1)0.5rRoller
xRoller target 1＝(yRoller-E)/C；
Solving for xRoller target 2
a＝x0R/(R+r)
b＝y0R/(R+r)
x1＝{R2a+Rb[(a2+b2-R2)0.5]}/(a2+b2)
y1＝{R2b-Ra[(a2+b2-R2)0.5]}/(a2+b2)
C＝(b-y1)/(a-x1)
E＝b-C·a-(C2+1)0.5(r roller + r cotton)
xRoller target 2＝(yRoller-E)/C
Second, compare xA roller,xRoller target 1、xRoller-target 2:
if xRoller target 1<xRoller+x<xRoller target 2In between, the X-direction moving power mechanism 7-5 is not started, that is, X' is equal to 0;
otherwise (simultaneously contain: x)Roller+x<xRoller target 1，xRoller+x>xRoller target 2Two cases)，The distance X ', X' by which the X-direction moving substrate 7-4 moves on the sliding substrate 2 satisfies:
xroller target 1<xRoller+x+x’<xRoller target 2
X' is calculated to be positive, indicating positive movement along the X axis; x' is calculated negative, the surface moves in the negative direction along the X axis;
thirdly, x isRoller+ x + x' assigning xRoller。
The steps of S3-3-4, S3-3-4 are the same as the steps of S3-2-4.
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.
