Problems solved by technology

[0002] At present, when testing the appearance of air conditioners, we can only rely on human perception to check the appearance quality to judge whether it is qualified, which has brought many impacts on the quality control of product appearance.
In the existing methods for detecting the appearance of air conditioners, since the specifications of the lighting fixtures used for detection are not uniform, and there are no standard requirements for installation angles and heights, it is not convenient to detect air conditioners with damaged appearance, resulting in the appearance inspection of air conditioners. Low yield

Abstract

The invention provides an appearance inspection method. The appearance inspection method comprises the following steps: a pretreatment step: detecting intensity of illumination on the outer surface of an object to be inspected, and regulating a light source according to the intensity of illumination to enable the intensity of illumination of the object to be inspected to reach a preset value; an inspection step: observing the object to be inspected to check whether the appearance of the object to be inspected is damaged. According to the appearance inspection method disclosed by the invention, before inspection of the appearance of the object to be inspected, the pretreatment step is conducted to regulate the intensity of indoor illumination to the preset value; under the preset intensity of illumination, whether the appearance of the object to be inspected is damaged can be observed conveniently, further the appearance damage situation of the object to be inspected can be inspected quickly and accurately, and the inspection rate of the appearance of the object to be inspected can be increased.

Description

technical field [0001] The invention relates to the technical field of product appearance inspection, in particular to an appearance inspection method. Background technique [0002] At present, when testing the appearance of air conditioners, we can only rely on human perception to check the appearance quality to judge whether it is qualified, which has brought many impacts on the quality control of product appearance. In the existing methods for detecting the appearance of air conditioners, since the specifications of the lighting fixtures used for detection are not uniform, and there are no standard requirements for installation angles and heights, it is not convenient to detect air conditioners with damaged appearance, resulting in the appearance inspection of air conditioners. The output rate is low. Contents of the invention [0003] The main purpose of the present invention is to provide an appearance detection method, which can quickly and accurately detect the obj...
