Abstract

Disclosed is a method for quality assurance in coating methods, characterized in that a plurality of parameters of the coating process are detected, compared with target values, which is given a deviation from a desired value an indication or the process can not be performed, and further the detected parameters stored in a database with assignment to the coating process.

Description

  • The invention relates to a method and a device for quality assurance in coating processes.
  • In coating processes, such as painting, an attempt is made to achieve a desired quality by strictly according to the specifications, for example, paint manufacturer is working. That is, certain parameters, such as temperature, viscosity of the paint and also parameters of the application process, for example in spraying, air supply, must be adjusted as accurately as possible according to the specifications of the manufacturer.
  • The object of the invention is to provide a method and a device for quality assurance in coating methods, in particular painting methods, which make it possible to reliably achieve and maintain the desired quality.
  • This invention is achieved by two basically independent modules, which can also be interconnected. According to the first module according to claim 1, a method for quality assurance is provided in which a plurality of parameters of the coating process are detected and these are compared with setpoints. If a deviation from a set point is detected, an indication is given to the operator or user of the method or the process can not be performed to avoid a faulty coating.
  • According to the second module according to claim 2 for quality assurance in coating process important parameters are recorded and stored in a database with assignment to the coating process. If quality issues are detected after performing the coating process, the parameters recorded in the database can be used to analyze why these problems occurred and how to resolve them.
  • Advantageously, both modules can be interconnected and used together to increase quality assurance.
  • Advantageously, parameters of the coating material, in particular of paint, are recorded. In this case, the temperature of the coating material and its viscosity can be detected. Usually, coating materials are stirred before application in order to bring them into a homogeneous state. Parameters of this stirring process, such as the stirring time, but also other parameters such as the stirrer used, speed, etc., can be sensibly detected. If multicomponent systems are used, it is expedient to detect the components used, in particular the respective amount, but possibly also their temperature and possibly viscosity, as well as the mixing time of the various components. Furthermore, useful information for the identification of the coating material used, for example, batch numbers are sensed. In particular, if quality problems occur after the coating process has been carried out, it is important to be able to identify the material used.
  • The idea of the invention is to record all parameters important for the quality of the coating and to compare them with predetermined nominal values. The mentioned parameters should only illustrate, with the recording of which parameter the quality can be increased. The person skilled in the art will be able to determine the essential parameters relating to the coating material in each coating process and make them available to the system in order to achieve the desired high quality.
  • Furthermore, it is advantageous to record parameters of the environment in which the coating process is carried out. These parameters also usually have a high influence on the quality of the coating process. The detection of the following parameters may be advantageous: air temperature and humidity. Usually, coating operations are carried out in rooms having controlled air circulation. In this case, it makes sense to record air circulation parameters, such as the volume of air supply and discharge per unit of time, and possibly also the actual speed of circulating air in the room, oxygen content and oil content of the ambient air. Furthermore, it may be advantageous to accurately detect parameters of the supplied air. Particular attention should be paid to the temperature and humidity of the supply air as well as the oxygen content and oil content of the supply air. The air pressure in the supply air duct should also be monitored.
  • Another area where parameters should be detected relates to the parameters of the article to be coated. In particular, the temperature of the object to be coated plays a significant role, which should be recorded and monitored. If so-called e-static is used during the coating process, ie if an electrical voltage is generated between the object to be coated and the coating device, the parameters characterizing the e-statics should also be recorded.
  • Often, during coating, the articles for finishing treatment to complete the coating result are fed to further processing stations. For example, objects are heated after the actual coating process, wherein special temperature profiles can be used to cure the coating material. Parameters that characterize these processes should also be recorded. In this regard, in particular the temperature of the coated article, ambient temperature, humidity of the environment and residence time in the processing station to think.
  • Advantageously, the object to be coated is identified before the start of the coating process. This can be done by a scan. This identification allows the coating parameters to be specifically assigned to the object.
  • Another parameter may be the intensity and / or the illuminance. The light intensity (Lux) of both the environment and the object to be coated and / or the coated object can be identified and stored, for example, in a database in order, inter alia, to be available there for quality assurance measures.
  • The system allows setpoints to be made available product-related. These setpoints can be made available, for example, by manufacturers of the coating materials. These values can be entered or updated directly by manufacturers in the system. It is thus possible for manufacturers, when supplying coating materials, to bring the corresponding nominal values directly into the system and thus no longer require updating by the user of the coating system, and the correct setpoints are always available, which has considerable advantages and contributes significantly to quality assurance.
  • Furthermore, after completion of the coating process, the system allows to enter data related to the coated article. Thus, data resulting from a test of the article or the coating of the article can be entered into the system. Here, for example, the layer thickness, and / or results of a visual inspection can be entered, but also person-related data, such as the identification of the processor who has performed the coating process. If quality problems arise later, these data can be evaluated and significantly contribute to the quality assurance of the process.
  • A suitable apparatus for carrying out the method has a first database in which predetermined data are stored and a second database in which new data can be stored. Furthermore, an input unit for inputting data as well as a computer for evaluation, in particular for comparing setpoint data with actual data are provided.
