Description

The present invention analyzes an electrolytic solution stored in a predetermined volume in an electrolytic cell for metal surface treatment in a metal anodizing apparatus, and adds sulfuric acid (sulfuric acid) to the electrolytic cell to maintain a constant voltage and current value of the electrolytic solution. The present invention relates to a metal anodizing system in which chemicals such as acid, H ₂ SO ₄ ) are automatically added.

In general, a metal anodizing (anodizing) apparatus is an oxidation that has a considerable adhesion with a base metal by oxygen generated at the anode when a metal or a component is applied to the anode and electrolyzed with a dilute acid electrolyte. A film (aluminum oxide: Al ₂ O ₃ ) is formed. Anodization is a compound word (Ano-dizing) of an anode (Anode) and oxidation (Oxidizing). Also, there is a difference between electroplating and plating with a metal part on the cathode. The most representative material for anodization is aluminum (Al), and besides that, magnesium (Mg), zinc (Zn), titanium (Ti), tantalum (Ta), hafnium (Hf), niobium (Nb), etc. Anodizing is also applied to metal materials. In recent years, the anodizing of magnesium and titanium materials has also been increasingly used.

  In general, anodizing (Alodizing on Aluminum Alloys), which treats an oxide film on the surface of an aluminum material, erodes half of the aluminum surface when aluminum is electrolyzed at the anode, and forms an aluminum oxide film on the other half. Aluminum anodizing (anodization) can form films having different properties depending on the composition and concentration of various electrolytic (treatment) solutions, additives, electrolyte temperature, voltage, current, and the like.

  As the characteristics of the anodic oxide film, the film is a dense oxide, excellent in corrosion resistance, improved decoration and appearance, the anodic film is quite hard and excellent in wear resistance, improves the paint adhesion, and bonds ( Bonding) performance is improved, lubricity is improved, a unique hue for decorative purposes is exhibited, plating pretreatment is possible, and surface damage can be searched.

Particularly, in the characteristics of hard anodic oxidation (hard anodizing), low temperature (or room temperature) electrolysis due to the alloy characteristics of aluminum is a low temperature electrolysis method in a sulfuric acid (H ₂ SO ₄ ) solution. It is a hard coating with wear and insulation properties, and it can be said to be hard if it is at least 30 μm or more. In this method, the surface of aluminum metal is changed to alumina ceramic by an electrochemical method. If this construction method is applied, the aluminum metal itself is oxidized to be changed into aluminum or ceramic, and the properties of the aluminum surface are stronger than steel and more excellent in wear resistance than hard chrome plating. The surface of the alumina ceramic that has changed without being peeled off like plating or painting (coating) is excellent in electrical insulation (1,500 V), but electricity flows well inside. A tip technique using a hard anodizing surface treatment method has been developed and applied to such an aluminum metal.

  Thus, in order to perform hard anodizing on aluminum metal, after immersing aluminum metal in an electrolytic bath containing an acidic solution, particularly an electrolytic solution in which sulfuric acid is dissolved, an oxide film is applied to the metal surface by applying a predetermined voltage and current. To form. At this time, the thickness of the oxide film varies depending on the voltage and current applied to the electrolytic cell. In addition, a voltage and a current value of a predetermined magnitude must be maintained in the electrolytic solution, but the voltage and the current value change depending on the concentration of sulfuric acid dissolved in the electrolytic solution. Therefore, a predetermined amount of sulfuric acid must be added to the electrolytic solution.

  In the conventional general plating, in the process of covering a metal surface with a film having a predetermined thickness, an operator can perform a desired plating with a simple skill level or using predetermined data. Although the quality could be guaranteed to some extent for the plating applied in this way, the metal anodizing surface treatment deposits several tens of alloys by the precipitation oxidation method on the metal surface. At this time, silicon, iron, copper, or the like that interferes with the anodizing surface treatment of the metal is also dissolved. Therefore, in order to remove foreign matter or dissolved aluminum remaining in the electrolyte during the metal anodizing surface treatment, a predetermined concentration of sulfuric acid is added to the electrolyte, and the thickness and hue of the coating can be uniformly treated by the sulfuric acid concentration. it can. That is, usually about 200 grams of sulfuric acid must be dissolved in one liter of electrolyte. However, since the concentration of sulfuric acid decreases during the metal anodizing surface treatment, a predetermined amount of sulfuric acid must be supplied to the electrolyte. Therefore, a predetermined voltage and current value must be maintained in the electrolyte, and sulfuric acid is added for this purpose.

  Therefore, the hard anodizing surface treatment of aluminum metal has made it possible for the worker to realize the thickness and hue of the metal oxide film with many years of skill. Also, skilled workers had to accept a certain percentage of defects. Therefore, anodizing surface treatment with a metal oxide film by an unskilled person or an amateur worker has led to the disadvantage of increasing the defect rate and inefficient productivity.

  Moreover, since the voltage and electric current value of electrolyte solution must be constant for uniform anodizing surface treatment of metal, the concentration of sulfuric acid dissolved in the electrolyte solution must also be constant. Therefore, it is not only troublesome to measure the concentration of sulfuric acid dissolved in the electrolyte solution and put a predetermined amount of sulfuric acid into the electrolytic cell, but it is more difficult to put an accurate amount of sulfuric acid. . Therefore, there is a problem that the time required for increasing the metal film thickness is increased, and manpower and cost for anodizing surface treatment of aluminum metal are increased.

  Of course, in order to solve such problems, the applicant has proposed Korean Patent No. 10-1048041. This relates to a sulfuric acid automatic charging device of a metal anodizing device. A metal anodizing device that immerses a plating object in an electrolytic bath in which the electrolytic solution is stored and anodizes the plating object by applying power to the electrolytic solution. A sensing device that is immersed in the electrolytic solution and senses the voltage and current value of the electrolytic solution; a power source applied to the sensing device is controlled, and the voltage and current values input from the sensing device are preset. A controller that compares a reference voltage and a current value and outputs a control signal; and a controller provided under a storage tank in which sulfuric acid is stored. The storage tank is opened and closed by the control signal of the controller, and sulfuric acid is supplied to the electrolytic cell through a pipe. A constant voltage and current value is maintained in the electrolyte stored in the electrolytic cell. Sulfuric acid of a predetermined amount by injecting, it is possible to enhance the work efficiency of the metal of the anode die Managing plated product quality improvement, productivity improvement, convenience and metal anodizing apparatus work.

  However, according to such a configuration, the sensing device is installed soaked in the electrolyte and measures the electrical conductivity of the electrolyte, so the electrical conductivity of the electrolyte is measured during the metal anodizing process. Therefore, there is a problem in that the sulfuric acid concentration is not accurately measured and the error is large.

  In particular, for more accurate measurement, it is necessary to measure the electrical conductivity in a state where the anodizing of the metal in the electrolytic cell is stopped. Since anodizing cannot be performed, it is difficult to continuously perform anodizing work, and electrical conductivity monitoring and sulfuric acid injection control are performed in an almost dangerous workplace, so the state of the electrolyte can be monitored remotely in a control room, etc. It is also difficult to do.

  Referring to FIGS. 1 to 3, the present invention accurately measures and senses the electrical conductivity of the electrolyte stored in the electrolytic cell 1 in real time and maintains a predetermined voltage and current value in a metal anodizing apparatus. Thus, a predetermined amount of a chemical such as sulfuric acid is automatically charged into the electrolytic cell 1, and a predetermined volume of electrolytic solution is stored in the electrolytic cell 1 of the metal anodizing device. At this time, the plating object 1a is immersed in the electrolytic cell 1, and the plating object is anodized by applying a power source having a predetermined size to the electrolytic solution.

  Meanwhile, an electrolytic solution measuring device 100 is provided on one side of the electrolytic cell 1 in order to measure the electrical conductivity of the electrolytic solution stored in the electrolytic cell 1, that is, a voltage and a current value of a predetermined magnitude.

  The electrolyte measuring device 100 is mounted in a container 110 in which an electrolyte flowing in through the water inlet pipe 102 is stored by driving a pump P1 into which the electrolyte stored in the electrolytic tank 1 flows, and in the container 110. And a positive (+) electrode 120 and a negative (−) electrode 130 for measuring electrical conductivity.

  Of course, the water intake pipe 102 is connected to one side of the container 110, and the water distribution pipe 104 for discharging the electrolytic solution inside the container 110 to the electrolytic cell 1 is connected to the other side of the container 110.

  At this time, the positive (+) electrode 120 and the negative (-) electrode 130 are installed while maintaining a distance from each other, and can be formed in a rod shape as shown, but the negative (-) electrode 130 is a cylinder. A negative (-) electrode 130 is integrally coupled to an inner wall of an insulator (not shown), and a plurality of through holes are formed in the negative (-) electrode 130 integrally coupled to the insulator. The positive (+) electrode 120 can be attached to the center of the cylindrical negative (−) electrode 130 at a constant distance from the negative (−) electrode 130.

  In this case, the insulator is made of synthetic resin, particularly PVC (polyvinyl chloride) pipe, and the negative (-) electrode 130 and the positive (+) electrode 120 can be made of metal, particularly lead, By using a platinum-treated metal material, it is possible to accurately detect the electric conductivity of the electrolytic solution by preventing foreign substances from sticking to each other, and the negative (−) electrode 130 and the positive (+) electrode 120 are detected. The fixing members 122 and 132 are preferably made of synthetic resin or metal as a nonconductor or insulating material, and the supporting members 122 and 132 are preferably made of synthetic resin or rubber.

  Of course, the positive (+) electrode 120 and the negative (−) electrode 130 are fixed to the terminals 124 and 134 and connected by the electric wires 125 and 135, and measured by the positive (+) electrode 120 and the negative (−) electrode 130. The power source, that is, the voltage and current values to be input is input to the controller 200, and the controller 200 controls the power source applied to the electrolyte solution measuring apparatus 100. The control signal is output by comparing the preset reference voltage and current value.

  On the other hand, the controller 200 compares the voltage and current values input from the electrolyte solution measuring apparatus 100 with a preset reference voltage and current value and outputs a control signal, and stores a drive program. The memory unit 220 stores all data input to the controller 200, and stores reference data related to temperature, voltage and current values and chemical input such as sulfuric acid. The input data stored in the memory unit 220 is reset as reference data for metal anodizing or utilized as a standardized database or data.

The controller 200 controls the driving of the pump P <b> 1 and causes the electrolytic solution in the electrolytic cell 1 to flow into the container 110 of the electrolytic solution measuring device 100. In this case, the controller 200 does not continuously circulate the electrolyte solution, and is driven during the set time to stop the operation after the container 110 is filled with the electrolyte solution, thereby setting the time (for example, 3 to 5 minutes). During this period, the voltage and current of the electrolyte are measured and compared with a preset reference voltage and current value.
Thereafter, the driving of the pump and the measurement process of the electrolytic solution can be repeatedly performed in a set time unit (for example, in units of 1 hour or 30 minutes), and the electrolytic cell 1 is maintained while maintaining such a reference voltage and current value. Within this, continuous metal anodizing is possible.

  Meanwhile, the controller 200 may further include a USB connection unit 250 and a communication unit 260.

  At this time, a USB memory 252 is connected to the USB connection unit 250, and voltage and current values measured at the positive (+) electrode 120 and the negative (−) electrode 130 are digitized and stored in the USB memory 252. . The numerical data accumulated and stored in this manner can be reset to reference data for metal anodizing or can be utilized later as a standardized database or data.

  The communication unit 260 can be operated in a wired / wireless manner, but can be composed of short-range wireless communication means such as Bluetooth or long-range communication means, and is used for control in a control room (for example, an office room). It is connected to the computer 300, and data can be transmitted and received in real time to check the control state of the pump P1 and the voltage and current value of the electrolyte at a remote place. Of course, it is also possible to control the driving of the controller 200 via the control computer 300.

  In particular, the control computer 300 outputs a warning sound through a buzzer or a speaker provided in the control computer when the control state of the pump and the voltage and current value of the electrolyte exceed or are less than the allowable values. Enable the administrator to take immediate action.

  On the other hand, an electromagnetic valve 410 is provided below the chemical storage tank 400 in which chemicals such as sulfuric acid are stored, so that the chemical storage tank 400 is opened and closed by a control signal from the controller 200 and is connected to the electrolytic cell 1 through the pipe 412. Add chemicals or block chemicals.

  The controller 200 has a thermometer 430 that is immersed in the electrolytic solution and senses the temperature of the electrolytic solution attached to the chemical storage tank 400, and monitors the temperature of the chemical charged in the electrolytic tank 1.

  In addition, the controller 200 visually displays the voltage and current values measured and sensed by the electrolytic solution measuring apparatus 100 and the amount and time of chemicals charged into the electrolytic solution through the electromagnetic valve 410. The unit 230 is further included.

  At this time, the display unit 230 is provided with a voltage indicator 231, a current indicator 232, a time indicator 233, and a temperature indicator 234.

  The display unit 230 is further provided with a toggle switch (T / S) so that the operator can select a power source.

  On the other hand, referring to FIG. 4, the controller 200 is provided with a toggle switch (T / S), and a power source applied to the electrolyte measuring device 100 can be selected. That is, by operating the toggle switch T / S, the AC power supply (AC) applied to the R end and the S end can be selected in one or two stages on the primary side of the transformer T, so that the transformer T The power source that is caused to the secondary side is applied. Then, the power source induced on the secondary side of the transformer T is rectified by the diodes D1 and D2, and a positive (+) DC power source is applied. The negative (-) DC power supply is provided with a timer T / S so that the DC power supply can be applied during the set time.

  In this case, in the present invention, when the chemical dissolved in the electrolyte is, for example, sulfuric acid, the concentration is 200 ± 50 g per liter, the sensed current is 10 ± 2 A, and the sensed temperature is 20 ± 1 ° C. Preferably, the sensed voltage is 15 ± 2V and the metal anodizing time is 30 ± 2 minutes. In particular, it is preferable that sulfuric acid contains a biosurfactant to promote bubble activation of the electrolyte.

  On the other hand, in the present invention, the thickness and hue of the plating are determined by the voltage and current values applied to the electrolytic cell 1 and the anodizing time. The controller 200 applies a predetermined voltage and current to the positive (+) electrode 120 and the negative (−) electrode 130 of the electrolytic solution measuring apparatus 100 via the electric wires 125 and 135. Between the positive (+) electrode (26) and the negative (-) electrode 130, a current flows through the electrolyte inside the container. At this time, the current value changes depending on the concentration of the chemical dissolved in the electrolytic solution, and the voltage value between the positive (+) electrode 120 and the negative (−) electrode 130 also changes. Therefore, the controller 200 measures and senses the concentration of the chemical dissolved in the electrolytic solution by sensing the voltage and current value between the positive (+) electrode 120 and the negative (−) electrode 130. Is. The controller 200 receives the temperature value of the electrolytic solution together with a thermometer 240 that is attached in the electrolytic cell 1 and measures the temperature of the electrolytic solution. The controller 200 stores the input data in the memory unit 220 and the USB memory 252, compares the input data with the reference data stored in the memory unit 220 and the USB memory 252, and stores the drug from the drug storage tank 400 in which the drug is stored. Whether or not it can be thrown in and the amount to be thrown in will be determined.

  In order to maintain a predetermined voltage and current value in the electrolytic solution, the concentration of the chemical dissolved in the electrolytic solution without opening the electromagnetic valve 410 if the concentration of the chemical dissolved in the electrolytic solution is within the set standard. If the value does not reach the set standard, the electromagnetic valve 410 is opened. At this time, the amount of chemicals introduced from the electromagnetic valve 410 is measured to monitor the shut-off time of the electromagnetic valve 410. Further, the controller 200 senses the temperature of the electrolyte and preheats the chemical storage tank 400. This makes it possible to minimize the defective rate of metal anodizing when the temperature of the electrolyte is lowered by introducing a chemical having a temperature lower than that of the electrolyte.

  All data input / output to / from the controller 200 is stored in the memory unit 220 and the USB memory 252 and can be used as reference data for metal anodizing. In addition, by creating standardized data in a table, the worker can perform improved metal anodizing only by monitoring the display unit 230 of the controller 200.

  Therefore, by allowing the electrolyte stored in the electrolytic cell 1 to maintain a constant chemical concentration, not only skilled but also amateurs can minimize the plating defect rate during anodizing. The chemical concentration can be accurately measured even during anodizing work, and highly reliable data can be secured and the chemical can be input, so that productivity can be improved.

And a pump P2 for feeding the electrolytic solution through the water pipe 14. With such a configuration, the electrolytic solution entering beyond the separation wall 4 of the electrolytic cell 1 is separated from the foreign matter by the filtration network 12 and re-entered into the electrolytic cell 1.

  Further, according to FIG. 6, a metal impurity removing device 20 is provided on the other side of the electrolytic cell 1 in order to adsorb metallic impurities dissolved in the electrolytic solution of the electrolytic cell for metal anodizing. At this time, the metallic impurity removing device 20 is attached to the filtration tank 21 and the filtration tank 21 so as to adsorb the metallic impurities dissolved in the electrolytic solution entering beyond the separation wall 5 of the electrolytic tank 1.

At this time, it is preferable that the metallic impurity adsorption filter 22 proposed by the present applicant in Korean Patent No. 10-1244166 is applied as it is.

  Of course, it is natural that both the pumps P2 and P3 are controlled by the controller 200. As shown in FIG. 7, the electrolytic solution can be obtained by continuously providing the degreasing device 10 and the metallic impurity removing device 20. However, it is also possible to adopt a configuration in which impurities such as oil are filtered while passing through the primary degreasing device 10 and then filtered secondarily while passing through the metallic impurity removing device 20.
