<\/div>\n<\/div>\n\nThe Application<\/h2>\n\n\nThe\u00a0PCB (printed circuit board) industry<\/strong>\u00a0forms the backbone of the electronics industry. Almost all electronics products contain some form of PCB. These boards connect various components together with\u00a0copper traces<\/strong>. Various types of machines are needed to process and move the PCBs. Some examples of these machines are conveyors, buffers, marking machines, loaders and unloaders, and traffic controllers. During the entire production process, the PCBs need to be reliably detected in order to\u00a0determine their location<\/strong>\u00a0for further processing.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n
\nThe Goal<\/h2>\n\n\nThe detection of PCBs is by no means a straightforward task. Some challenges are\u00a0different colors, textures, and reflectivity<\/strong>\u00a0(from dull matt to shiny) of the PCB surface. Further challenges are\u00a0non-detection of holes and notches<\/strong>\u00a0in the PCB or\u00a0non-detection of shiny background objects<\/strong>. Other tasks would be the detection of components on PCBs or the accurate detection of PCB edges to determine an\u00a0accurate stop position<\/strong>. Furthermore, the sensors used for detecting the PCBs need to be very small in order to fit into the machines and need to offer simple mounting, where ideally no adjustment is needed.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n
\nThe Solution<\/h2>\n\n![\"ML100-8-HGU-100-RT\/102\/115\/162](\"https:\/\/www.pepperl-fuchs.com\/singapore\/images_inet_lowres_ZHI\/EC_CM_20210823_ML100_200px.png\")
\nML100-8-HGU-100-RT\/102\/115\/162 convergent beam sensor<\/span><\/div>\n\nThe\u00a0ML100 convergent beam sensor<\/strong>\u00a0is the best solution for the application due to a few properties. First, the sensor offers an\u00a0elongated light spot<\/strong>, which ensures that even under travel over holes and notches on the PCB, the device remains in the\u00a0\u201cON\u201d state<\/strong>. This is because the light spot ignores the holes and notches while the other portion of the light spot is still detecting the PCB. Secondly, the sensors\u2019\u00a0slim and well-defined light stop<\/strong>\u00a0enables accurate detection of the stop position. And thirdly, the sensor reliably detects PCBs with all types of color and texture due to its\u00a0superior optical design<\/strong>. In summary, the elongated light spot and the\u00a0excellent optical performance\u00a0<\/strong>are the key to the success of the sensor in this application. With this configuration, the sensor detects the PCB once it enters the light spot and does not switch off when it travels the length of the entire PCB. When moving the PCB perpendicular to the length of the light spot, the sensor ensures that the\u00a0stop position is accurate as determined<\/strong>\u00a0by the slim light spot.<\/p>\nTechnical Features:<\/strong><\/p>\n\n- Stable detection on all surfaces, including shiny PCBs<\/li>\n
- Elongated light beam ignores holes and notches on PCBs<\/li>\n
- Accurate detection of PCB position due to slim light spot<\/li>\n
- Excellent optical performance for stable detection of different PCBs<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n
<\/p>\n
\nThe Advantages<\/h2>\n\n\nThe ML100 convergent beam sensor has\u00a0excellent optical performance<\/strong>\u00a0and therefore little issues detecting PCBs of various reflectivity. In addition, mounting and aligning the ML100 series is simplified by a\u00a0red emitter LED\u00a0<\/strong>and\u00a0integrated all-metal threaded bushings<\/strong>. The switching states are also easily visible from all directions due to the highly visible LEDs.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n
