AOI Inspection Machine SMT patches and inspection equipment
1. AOI principle: use modern optical principles and digital camera technology to shoot the detected object in real time, analyze and process the captured image through computer and special software, and automatically generate detection results.smd machine smt machines
2. AOI function: AOI effective detection rate: more than 99% (manual detection rate: about 70%);smt machine
Reduce labor: 2-4 people/production line, high detection efficiency;pick and place machine
Through the SPC function, the process defects can be accurately counted and can be effectively controlled;smt pick and place machine
The stability is much higher than that of labor, long-term use, the comprehensive cost can be significantly reduced;pick place machine
It can enhance the company's comprehensive strength and effectively improve the company's overall competitiveness.smd pick and place machine
3. AOI advantages:
1) Inspectable items:pick and place smd machine
After the wave soldering of the DIP plug-in: more tin, less tin, tin hole, short circuit, pin not out, etc.surface mount device
SMT: missing parts, misalignment, wrong parts, polarity reverse, breakage, pollution, less tin, more tin,
smt placement equipment short circuit, virtual soldering, etc.
As shown in Figure (1) above, all the detection items of polar dichograms. Its registration and debugging are as follows:
Component type | Detections | Description |
Polar two-legged pieces | Ontology frame | The function of the body frame is to position and offset. Its registration and debugging are described in the "< Basic detection items for wave soldering ><Offset>Offset" algorithm using the "NCC" algorithm. |
Less tin frame | The role of the solder frame is to detect the creeping condition of the solder joint. Its registration and debugging are shown in the "< Basic detection items for wave soldering>< Less tin>less tin" algorithm using the "COLOR" algorithm. | |
Empty weld frame | The purpose of the empty welding frame is to detect whether the solder joint has been empty welded. Its registration and debugging are shown in < Basic detection items for wave soldering >the "< Empty welding>Air Welding" algorithm using the "COLOR" algorithm. | |
Wrong part box | The function of the wrong part frame is to detect whether the solder joint is the wrong part, side standing, standing monument, and white. Its registration and debugging are described in the "< Basic detection items for wave soldering>< Wrong piece>Wrong Parts" algorithm using the "NCC" algorithm. | |
Missing parts box | The function of the missing part box is to detect whether the component is missing parts. Its registration and debugging are described in the "< Basic detection items for wave soldering>< Missing pieces>Missing Parts" algorithm using the "Histogram" algorithm. |
Tip: When the body of the polar two-legged part has silk screening, the polar frame and the wrong part frame are the same detection frame.
