Abstract

The invention discloses a mask ear loop welding detection method with ear loops facing outward, which comprises the following steps: preset standard mask connection points, perform convolution operation and visual inspection on the mask to be tested, and obtain the connection points of the mask to be tested, Judging that the deviation between the connection point of the mask to be tested and the connection point of the standard mask is greater than the set threshold, the mask to be tested is an unqualified product for ear strap welding. The invention of the present application avoids processing the texture of the solder joints of the ear straps, has high accuracy of detection results, and is less difficult to debug in practical applications, and is compatible with all masks produced with the ear straps facing outward.

Description

technical field [0001] The invention relates to the technical field of mask ear loop welding detection, in particular to a method for detecting mask ear loop welding with the ear loop facing outward. Background technique [0002] A mask is a hygienic product used to filter the air entering the mouth and nose, and protect the human respiratory system and physical health. Wearing a mask on the human body can protect and filter out droplets, dust, exhaust gas and other germs and pollutants that affect health from entering the human body. internal. The mask mainly includes a mask body made of multi-layer filter materials, nose ribs and ear straps. The ear straps need to be connected to the mask body by welding. During the mask production process, the welding quality of the ear straps needs to be tested to ensure the quality of the mask. In actual application, the welding quality inspection of ear straps is to detect and judge the connection point, where the connection point is ...
