Machine vision inspection technology is the most basic technology to ensure mass mount production, and it is also the fundamental reason for its application and value. Machine vision inspection system is used in common electronic materials, active components, IC packaging, passive components and finished electronic equipment to promote high-quality production and reduce costs.
At present, the size of surface mount components (SMD) of electronic products has become smaller and smaller, even as small as a few millimeters or even smaller, such as common electronic components such as transistors, capacitors, resistors and other components, in order to achieve higher density mounting on printed circuit board PCB and realize more existing functions. The decreasing size and increasing function greatly improve the performance of electronic equipment.
Visual inspection system products have very powerful visual tools. Under the application of this machine vision system, after the deployment of relevant technical training professionals, electronic production engineers can use machine vision to continuously meet the stringent production and packaging requirements to ensure product quality and safety. Thus, the application value of machine vision in the industrial field can be seen.
Machine vision can use two-dimensional and three-dimensional aspects to locate the PCB on the tray, guide the high-speed pick-up robot to single SMD components for picking, guide the robot arm back to the PCB to place the SMD, and finally verify the welding connection to confirm whether each SMD lead passes through the PCB or through the mounting hole. In these areas with high precision requirements, the advantages of machine vision are very obvious. It can complete the positioning work that people and even robots can not complete.
In addition, because the components on the circuit board are so dense, if manual method is used, it is impossible to carry out welding verification. However, the use of machine vision can not only verify the connection of circuit boards, but also provide defect feedback for manufacturing engineers to leave analysis data and basis even in case of welding cracks, insufficient reflow or other process characteristics.
The use of machine vision inspection system can meet the requirements of manufacturers to automatically check the spacing between components is becoming smaller and smaller, which is the real value of the visual inspection system.
