Problems solved by technology
[0004] Coating tools usually operate automatically according to the set operating parameters, but for the same coating tool, even if the same operation is performed on the same part of the same product at the same position, it will still be affected by complex factors such as material viscosity and operating temperature. Factors, resulting in the coating thickness may change at any time

The invention relates to a quality monitoring method, system and apparatus based on a coating thickness value and a medium. The quality monitoring method based on the coating thickness value comprises the following steps that: a coating thickness data set is acquired, wherein the coating thickness data set comprises at least one coating thickness value obtained by measuring the coating thickness of a coating at the same position of the same part of at least one same coated product sequentially coated by the same coating tool through a standard measuring tool; and the coating thickness data set is analysed to determine if operating parameters of the coating tool need to be adjusted. According to the quality monitoring method, system and apparatus based on the coating thickness value and the medium of the embodiment of the invention, the change of the coating thickness value of the coated product can be monitored, and subsequent possible coating defects / non-ideal coating can be predicted based on the analysis of the coating thickness value of the coated product, so that the operating parameters of the coating tool can be adjusted in time to provide more stable and better coating quality.
Description
technical field [0001] The disclosure relates to product quality management, in particular to a quality monitoring method, system, device and medium based on coating thickness values. Background technique [0002] Painted products, such as painted automobiles, typically have a paint film consisting of two coats of primer and an outermost clearcoat. After the car is painted, a standard measuring robot is generally used to monitor the thickness of each paint layer in the paint film. Measured thickness data is used to determine whether each paint layer of the painted product is compliant, if not, respray may be required. [0003] When painting a product such as an automobile, the thickness of each coating needs to fall within a corresponding predetermined range in order to present a qualified painting effect. For example, for the outermost varnish layer, it may be desired that its thickness is between 45-65 μm. If the thickness of the actual varnish layer is less than 45 μm, ...
