Mobile phone battery size and appearance defect detection system and detection method

Abstract

The invention discloses a mobile phone battery size and appearance defect detection system. The system comprises the following components of: a light source; an optical imaging system; an image capture system which communicates with the optical imaging system; an image acquisition and digitization system which communicates with the image capture system; an intelligent image processing and decision-making system which communicates with the image acquisition and digitalization system and the light source; and a control execution module which communicates with the intelligent image processing and decision making system. According to the detection system and detection method of the invention, a hardware detection platform is established, camera calibration is realized, and pre-processing such as median filtering and edge detection is carried out on collected pictures; for the appearance defect detection of a mobile phone battery, the defects of the detected pictures are judged to obtain information such as the size, the number and the position of the defects, so that the surface defects are detected.

Description

technical field [0001] The invention relates to the technical field of mobile phone battery size and appearance defect detection, and more specifically, relates to a mobile phone battery size and appearance defect detection system and detection method. Background technique [0002] Mobile Internet technology is gradually popularized and applied in daily life. As a terminal of modern communication, mobile phone has become a necessity in people's daily life. Correspondingly, the demand for mobile phone batteries is also increasing, and the requirements for its size and appearance defects are also increasing. High, each mobile phone battery has corresponding characters and patterns, indicating the date of manufacture, manufacturer, precautions, etc. of the mobile phone battery, which requires a lot of time to judge whether the printed patterns and text on the battery surface meet the specified standards. Determine whether the size of the battery meets the specified standards. ...

AI Technical Summary

Problems solved by technology

[0003] In the industrial field, the accuracy of the size and appearance defect detection of mobile phone batteries is getting higher and higher. At present, in the manufacture of mobile phone batteries, the size measurement and surface defect detection are all done manually, which is time-consuming and labor-intensive, and it is difficult to meet the detection requirements. and various standards

The traditional precision measurement method is to measure the mobile phone product by the measurer through the measuring tools such as the microscope instrument and the caliper. error occurred

Moreover, in the face of mass production, many companies often choose the method of random inspection, which cannot directly reflect the overall situation of the product. In addition, long-term measurement work will make the measurement personnel tired and cause measurement errors. Therefore, the traditional measurement method can no longer meet the needs of modern production. need
