Research on Automatic Detection Device of PCBA Solder Defects in Automobile Steering Gear
In order to improve the efficiency of welding detection in automatic Assembly line of automobile steering machine,the automatic defect detection technology is applied to the automatic solder welding production of automobile steering machine Printed Circuit Board Assembly(PCBA),and then the automatic solder welding detection device of automobile steering machine is developed.On the one hand,the hardware equipment such as controller,electric cylinder and camera are selected and designed.On the other hand,the image recognition and feature extraction algorithms of solder joints are designed.In the field,several groups of products were photographed,and a lot of tests were carried out on the collected solder joint images.The results show that the accuracy rate of the device is 98.2%,the false detection rate is 1.2%,the missed detection rate is 0.6%,and the average detection time of each image is 122.47 ms,which meets the quality requirements of the project and effectively improves the detection efficiency and reliability of PCBA tin welding defects.
