Research On Vision Detection System Applied To The Circuit Board Gluing Quality Of Automobile Sensor

With the rapid development of the electronic technology, computer technology and the modern network technology, The traditional detection methods cannot meet the needs of modern industrial development, has a good real-time, visual and intelligent high online image detection technology has been widely used in industrial automation, automotive, aerospace and other fields. The so-called online image detection technology, Using image processing technology, image detection technology and the combination of industry automation technology to realize the target of observation and detection. In the last few years, This field has been gradually moving towards high-end, And widely used in automobile manufacturing. The design and study of Vision Detection System Applied to the Circuit Board Gluing Quality of Automobile Sensor, Not only to be more perfect this fields, and to ensure the detection precision, raise the production efficiency, lower the determination cost, actively promote the development of electronic technology in automotive manufacturing.Image processing module is the core content of this paper, in this paper, Through a set of Image Collection System to complete image collection for the detecting element, such as LED light source, CCD camera and image acquisition card. On the basis of the LabVIEW software program editor, Location of target image is realized by using multiple template matching, and complete the image processing; Calculating each region gluing area percentage of the image to be detected by using Image Segmentation Algorithm, compare whether meet the setting percentage threshold.Realizing the detection of the circuit board gluing quality of automobile sensor.The automobile sensor circuit board glue, can play a role in protecting the circuit, waterproof and moistureproof. To ensure that gluing area of the sensor circuit boardisintact, the non-gluing area is not glued, making the performance of the circuit board has been assured that the quality of the sensor has been improved.To the design of the vision detection system applied to the circuit board gluing quality of automobile sensor, solve the deficiency of the traditional manual detection method, such as low precision, low efficiency and high cost of detection affected by external environmental factors, has realized the detection that is non-contact, visualization and intelligent.
