Description
Technical field
The utility model relates to etchant concentration and measures opertaing device field, particularly relates to a kind of concentration of oxalic acid controller.
Background technology
TFT, touch-screen ito film etching solution amount ratio are comparatively large, necessary 24H continuous seepage, and control to carry out in real time to etchant concentration, with chemical titration, the cycle is long, and needs off-line measurement, can not well monitor in real time.In process of production, in order to save the consumption of ito film etching solution, ito film etching solution needs Reusability to reality, and an addition, at about 400L, therefore needs to measure to ensure that liquor strength is in certain controlled range to concentration of oxalic acid in real time.
Utility model content
The purpose of this utility model is: provide a kind of concentration of oxalic acid controller, relevant to conductance profile according to the concentration of oxalic acid liquid, the real-time concentration of liquid is gone out by the Conductivity Calculation measuring liquid in real time, and according to real-time concentration, moisturizing is carried out to system, ensure that liquor strength is in certain controlled range, decreases the impact of fluctuation of concentration on product quality.
To achieve these goals, the technical solution of the utility model is:
A kind of concentration of oxalic acid controller, comprises main engine bed, metering supply portion and measures control part; Described metering supply portion comprises acid solution inlet port, acid solution refluxing opening and water purification supply mouth; Acid solution to be measured enters to flow through behind described metering supply portion from described acid solution inlet port and flows out from described acid solution refluxing opening; Described metering supply portion provides part described acid solution to be measured to described mensuration control part; Described mensuration control part is measured the conductivity of described acid solution to be measured and is sent supply instruction to described metering supply portion, controls described water purification supply mouth and provides water purification supply to described acid solution refluxing opening.
Further, described metering supply portion also comprises water purification supply opening, is connected to outside water purification source.
Further, also discard solution discharge port is comprised.
The utility model is owing to have employed above-mentioned technology, and the good effect making it compared with prior art to have is:
The utility model measures control part and metering supply portion owing to being provided with, by measuring the conductivity of liquid in real time, according to concentration and the conductance profile relation of oxalic acid liquid, calculate the real-time concentration of liquid, and according to real-time concentration, moisturizing is carried out to system, ensure that liquor strength is in certain controlled range, decreases the impact of fluctuation of concentration on product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model concentration of oxalic acid controller.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of concentration of oxalic acid controller, comprises main engine bed 1, metering supply portion 2 and measures control part 3; Described metering supply portion 2 comprises acid solution inlet port 4, acid solution refluxing opening 5 and water purification supply mouth 8; Acid solution to be measured from described acid solution inlet port 4 enter flow through described metering supply portion 2 after flow out from described acid solution refluxing opening 5; Described metering supply portion 2 provides part described acid solution to be measured to described mensuration control part 3; Described mensuration control part 3 is measured the conductivity of described acid solution to be measured and is sent supply instruction to described metering supply portion 2, controls described water purification supply mouth 8 and provides water purification supply to described acid solution refluxing opening 5.
Preferably, described metering supply portion 2 also comprises water purification supply opening 7, is connected to outside water purification source.
Preferably, also comprise discard solution discharge port 6, discharge for the waste liquid in concentration of oxalic acid controller.
The utility model is by measuring control part 3 by measuring the conductivity of liquid in real time, according to concentration and the conductance profile relation of oxalic acid liquid, calculate the real-time concentration of liquid, and according to the rate of water make-up that real-time concentration certainty annuity needs, then instruction is sent to metering supply portion 2, by water purification supply mouth 8 to acid solution refluxing opening 5 supply water purification, ensure that liquor strength is in certain controlled range, decreases the impact of fluctuation of concentration on product quality.
Shown in Figure 1, according to Production requirement, board feed flow is given from TANK (liquid reserve tank) the A or TANK B etching machine bench 10, the utility model concentration of oxalic acid controller supply liquid is given by acid solution inlet port 4 while feed flow, measure the conductance that control part 3 records feed flow, and calculate the concentration of liquid to be measured, and then calculate amount and the time of moisturizing, concentration is inclined must be higher, and the relative moisturizing time is longer.
In sum, the utility model, according to the conductivity of liquid, calculates the concentration of liquid in real time, and controls, and can better ensure the quality of product, and the effective serviceable life extending liquid, reduce cost of use.
