Description

[0001] PLATING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coating apparatus used for coating a material in an electrodeposition painting test process, and more particularly, to an improved coating apparatus capable of accurately maintaining coating conditions of a material, thereby improving the reproducibility and reliability of the coating.

In general, materials produced in the steel manufacturing process are subject to various quality certification tests and evaluations depending on the purpose of use.

Materials produced for household appliances and automobiles are subjected to various quality certification tests and evaluations according to the purpose of use. For example, materials produced for home appliances and automobiles are subjected to electroplating through various processes for the purpose of conducting experiments such as corrosion resistance and adhesion, and quality certification and evaluation are carried out in accordance with the intended use of the coating material.

Electrodeposition coating deposits a number of materials processed to a certain size in the prepared coating solution and conducts the painting work using the current supply method.

Most of the electrodeposition coating methods used in laboratories depend on manual work by the operators, and there is no electrodeposition coating equipment for quality certification experiment and evaluation progress.

Electrodeposition coating experiment is a factor that influences the mixing ratio of the coating solution, temperature, voltage, total polar ratio and agitation force.

The temperature of the coating solution is adjusted to the temperature of the coating solution by indirectly depositing the container in boiling water in a state of storing the coating solution in a beaker or a constant container, and then performing an electrodeposition coating.

When the temperature drops, the above procedure is repeated. Because it is difficult to control the temperature accurately, the problem of reproducibility and reliability arises due to enlargement of experimental deviation.

Repetition of the process during the experiment reduces the time, efficiency of the experiment, and the efficiency of the operator.

In the conventional coating apparatus, the coating solution can be adjusted to a predetermined temperature by heating the coating solution storage container or the beaker using boiling water. Then, the anode is connected to the coating solution storage container or the beaker, and the cathode And the rectifier is operated to perform electrodeposition coating.

However, in the conventional coating apparatus, the coating layer is unevenly formed due to unevenness in the mixing ratio of the coating solution stored in the container used as the material and electrode, and the adhesion of the coating layer formed on the material is remarkably reduced. Also, in the conventional art, there is a high possibility that an electric shock accident or the like may occur during the test as the coating solution storage container is exposed in a state of being charged with the anode.

Further, conventionally, it is necessary to stir the plating solution so that the plating solution is well coated on the workpiece during the electrodeposition coating process for coating the workpiece.

To this end, the conventional coating apparatus may be provided with a stirrer having a stirring blade operated by a motor. The stirrer is fixed using a holder, and a stirring blade to be connected to the motor of the stirrer is inserted into the storage container and is stirred as the rotating blades are rotated.

However, the conventional stirrer may cause interference with the storage container or the material due to vibrations generated by the operation of the motor or the like,

Therefore, it is required to retest due to interference with the material, cause damage to the equipment, and cause the coating solution to overflow around the painting or stirring process, thereby causing environmental pollution.

It is an object of the present invention to provide a coating apparatus which can be repeatedly used to paint a material for evaluation and evaluation of quality of a coating layer formed on the material and can reproduce the same coating conditions .
