FIG. 3 is a flow chart of a bath compensation analysis method according to an embodiment of the present invention. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.
Step S1: and acquiring the tank body information and the concentration detection value of the tank liquid parameter in the tank body.
The tank body is a medicine tank containing tank liquid in the anodic oxidation process, and the tank body can be one of a degreasing tank, a black film stripping tank, a chemical polishing tank, an anodic oxidation tank and a hole sealing tank. The bath parameters can be chemicals in the bath or can be specific components. For example, the tank is an anodic oxidation tank, and the tank parameters include the concentration of sulfuric acid and the concentration of aluminum ions.
The slot body information includes at least one of a slot position number, a slot position name, a slot body type and a slot body volume.
When the concentration detection value of the bath solution parameter is obtained, a bath solution sample can be automatically collected, and the concentration detection value of at least one bath solution parameter is obtained after the bath solution sample is analyzed. The method of analyzing the bath solution can be a calibration method. In one embodiment, the concentration of the main component is analyzed according to the concentration of the standard solution, the amount of the standard solution and an operation model corresponding to the bath solution parameters, wherein the operation model comprises an empirical coefficient corresponding to the detection item.
Step S2: and judging whether the concentration detection value is smaller than a corresponding first preset threshold value.
And comparing the concentration detection value with a corresponding first preset threshold value to judge whether the concentration detection value is smaller than the first preset threshold value. And the first preset threshold is the lower limit value of the normal concentration range corresponding to the bath solution parameter. If yes, chemicals are required to be added, and the step S3 is carried out; if not, the process returns to step S1.
Step S3: analyzing one or more chemicals to be added into the groove body.
Specifically, according to the tank body information and the tank liquid parameters, one or more chemicals to be added to the tank body are analyzed.
Step S4: when the chemical to be supplemented is one, the amount of the chemical to be supplemented is analyzed by a first analysis method.
Specifically, the first analysis method is as follows: and matching corresponding operation logics according to the tank body information and the tank liquid parameters, and analyzing the addition amount of the chemicals through the corresponding operation logics.
It can be understood that the operation logic in the first analysis method is classified according to the slot type and the detection parameter, and the operation logic is the same for the same type of slot and the same detection parameter.
In one embodiment, the arithmetic logic for analyzing the chemical addition amount by the first analysis method is m ═ c (c)1-c2)*V*f1(ii) a Wherein m is the addition of chemicals, c1As a concentration standard value, c2V is the volume of the tank body, f is the concentration detection value1To adjust the scale factor, f1Is a variable related to the slot information.
Step S5: when the chemicals to be supplemented are multiple, the addition amount of the multiple chemicals is analyzed by the second analysis method.
Referring to fig. 4, fig. 4 is a flowchart of a second analysis method. Step S5 specifically includes the following steps.
Step S51: the feeding height of each chemical was analyzed.
The method is described below by taking a chemical polishing bath as an example. The chemicals to be supplemented comprise a first chemical and a second chemical, wherein the first chemical is sulfuric acid, and the second chemical is phosphoric acid.
The first chemical is supplemented to a height h1＝(c2/ω2/ρ2*V/f/f1-c1/ω1/ρ1V/f)/a/b; the second chemical is supplemented to a height h2＝(c1/ω1/ρ1*V/f/f1-c2/ω2/ρ2V/f)/a/b, wherein c1、c2Respectively detecting the concentration of the first chemical and the concentration of the second chemical; omega 1 and omega 2 are respectively the mass percentage of the first chemical product and the second chemical product; rho1,ρ2Density of the first chemical and the second chemical, respectively; v is the volume of the tank body; f is a volume correction factor; f. of1Is a scaling standard coefficient; a. b is the length of the groove body and the width of the groove body respectively.
Step S52: and analyzing the addition amount of the various chemicals by using the operation logic corresponding to the chemicals with the addition height being a positive value.
According to the formula of the supplement heights h1 and h2, one of h1 and h2 is positive and the other is negative. After the supplement height of the chemical is analyzed in step S51, the operation logic corresponding to the chemical with the supplement height being a positive value is selected.
Specifically, the step of analyzing the replenishment amounts of the plurality of chemicals by using the operation logic corresponding to the chemical having the replenishment height of a positive value is specifically:
step S521: and judging whether the liquid level needs to be supplemented independently.
Specifically, whether the current liquid level of the tank body is lower than a control threshold of the liquid level or not is judged, and if yes, the liquid level needs to be supplemented independently.
Step S522: if separate liquid level replenishment is required, the replenishment amount for each chemical is calculated separately.
If the supplement height of the first chemical is a positive value, the operation logic of the supplement amount of the first chemical is m1＝a*b*(H-h1)/(f1+1)*ρ1+a*b*h1*ρ1The operation logic of the supplementary addition amount of the second chemical is m2＝a*b*(H-h1)/(f1+1)*f1*ρ2Wherein H is the liquid level difference to be supplemented.
If the supplement height of the second chemical is a positive value, the operational logic of the supplement amount of the first chemical is m1＝a*b*(H-h2)/(f1+1)*ρ1The operation logic of the supplementary addition amount of the second chemical is m2＝a*b*(H-h2)/(f1+1)*f1*ρ2+a*b*h2*ρ2。
Step S523: and if the independent liquid level supplement is not needed, calculating the supplement amount of the chemicals with positive supplement height, and the chemicals with negative supplement height do not need to be supplemented.
In the above exemplary embodiment, if the replenishment level of the first chemical is positive, the operation logic for calculating the replenishment amount of the first chemical is: m1＝a*b*h1*ρ1(ii) a The amount of the second chemical added, M2, was 0 and was not added.
If the supplementary height of the second chemical is a positive value, the operation logic for calculating the supplementary amount of the chemical with the supplementary height of the positive value is as follows: m2＝a*b*h2*ρ2(ii) a The amount of the first chemical added, M1, was 0 and was not added.
In one embodiment, after the step S4 or S5, the bath compensation analysis method further includes the steps of: and generating a slot position compensation analysis report. The analysis report comprises compensation information of the plurality of tanks, so that a user can comprehensively know the state of the anodic oxidation process and conveniently inquire the state.
After the step S4 or S5, the bath compensation analyzing method further includes the steps of: and analyzing the supplement specification of the chemicals according to the basic information of the supplement chemicals. The basic information of the chemicals includes chemical names, chemical packaging specifications, drug categories, and the like. For example, for a degreasing tank, the tank liquid parameter is hydrochloric acid, the concentration detection value is 7.2, the concentration standard value is 8, and the analyzed addition amount is 2 packets of hydrochloric acid with a preset specification.
In one embodiment, after obtaining the concentration detection value of the bath liquid parameter in the bath body, the method further comprises: judging whether the concentration detection value is larger than a corresponding second preset threshold value, wherein the second preset threshold value is an upper limit value of a normal concentration range; if so, the amount of the bath solution to be discharged outside the bath body is analyzed.
The tank liquid compensation analysis method can obtain tank body information and a concentration detection value of a tank liquid parameter in the tank body; judging whether the concentration detection value is smaller than a corresponding first preset threshold value or not; when the concentration detection value is smaller than a first preset threshold value, analyzing one or more chemicals to be added into the tank body; when one chemical to be supplemented to the tank solution is needed, analyzing the supplement amount of the chemical by a first analysis method; and when the chemical to be supplemented to the tank solution is multiple, analyzing the supplementary amount of the chemical by a second analysis method.
Therefore, the tank liquid compensation analysis method can automatically judge whether the tank body needs to be replenished or not, analyze the type of the chemical to be replenished and automatically analyze the replenishment amount of the chemical according to the type of the chemical. The tank liquor compensation analysis method replaces a manual operation mode, improves the operation efficiency and accuracy of compensation analysis, reduces the difference range of the concentration of the tank liquor after drug supplementation, and avoids the risk of tank discharge caused by excessive compensation.
In addition, the tank liquor compensation analysis method can simultaneously analyze a plurality of tank positions, has high operation speed, can realize cloud storage of big data, historical data query and data sharing of different units, and meets the requirements of modern production.
