AOI Inspection Machine SMT patches and inspection equipment
1. Product introduction
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.
2. AOI function: AOI effective detection rate: more than 99%
(manual detection rate: about 70%);
Reduce labor: 2-4 people/production line, high detection
efficiency;
Through the SPC function, the process defects can be accurately
counted and can be effectively controlled;
The stability is much higher than that of labor, long-term use, the
comprehensive cost can be significantly reduced;
It can enhance the company's comprehensive strength and effectively
improve the company's overall competitiveness.
3. AOI advantages:
1) Inspectable items:
After the wave soldering of the DIP plug-in: more tin, less tin,
tin hole, short circuit, pin not out, etc.
SMT: missing parts, misalignment, wrong parts, polarity reverse,
breakage, pollution, less tin, more tin, short circuit, virtual
soldering, etc.
Polar two-legged pieces
Polar bilegs, including polar bipedals, diodes and other
components, which are also common components of solder after the
furnace.
This type of component device has polarity (directionality), some with silk screen printing, and the silk screen printing is mostly fuzzy screen printing;
Some have polarity markings, which are mostly a fixed area of the
component. Its registration diagram is as follows:
In the figure above, the red box is the main frame, the blue box is
the less tin (empty welding, missing parts) box,
the purple box is the wrong part box, and the yellow box is the polar box. Its registration form is as follows:
As shown in Figure (1) above, all the sensing items for resistors. Its registration and debugging are as follows:
| Component Type | Detection Item | Description |
| resistance | 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 ><Offset>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 (missing) 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 "Error" algorithm < Basic detection items for wave soldering>< Wrong piece>using the "OCV" algorithm. |
Tip: The missing frame of the resistor is the same detection frame as the wrong part frame, which mainly detects silk screening.
