SAKI 2d aoi smt Automated Optical Inspection machine BF-LU1

SAKI BF-LU1 is a high-performance two-dimensional automatic optical inspection equipment (AOI) dedicated to the quality inspection of PCB (printed circuit board) in SMT (surface mount technology) production lines. The equipment uses high-resolution optical imaging + AI intelligent algorithm to quickly identify problems such as solder joint defects, missing parts, wrong parts, and polarity errors to ensure quality control of the electronic assembly process.

3. Core features

(1) High-precision optical imaging

Adopt high-resolution CCD camera with multi-angle LED light source to ensure clear imaging of solder joints and components.

Supports red, green, blue and white light combination to enhance the contrast of different materials (such as solder and plastic components).

(2) Intelligent detection algorithm

Based on AI machine learning, automatically identify solder joint defects (low tin, high tin, bridge, cold solder joint, etc.).

(3) Flexible programming and automation

Support CAD file import, automatically generate detection programs, and reduce manual setting time.

(4) Efficient production integration

Can be linked with SMT placement machine, reflow soldering, and MES system to achieve real-time defect feedback and automatic sorting.

4. Main functions

(1) Solder joint detection

Solder paste printing detection (low tin, high tin, offset, bridge).

BGA/QFN solder joint detection (cold solder joint, missing ball, offset).

(2) Component detection

Missing components, wrong parts, reverse polarity, offset, monument.

(3) Data management

Storage of detection results, SPC trend analysis, and NG/OK data export.

Support barcode scanning to achieve PCB traceability.

(4) Production line linkage

Communicate with MES system to achieve automatic sorting or alarm shutdown.

5. Operation precautions

(1) Environmental requirements

Temperature: 15~30℃ | Humidity: 30~70% RH

(2) PCB placement

Ensure that the PCB is flat and fixed to avoid warping that affects imaging.

The conveyor track must be kept clean to prevent jamming.

(3) Light source calibration

Check the uniformity of the light source when starting the machine every day, and perform white balance calibration if necessary.

(4) Software settings

Select a dedicated inspection template according to the component type (BGA, CHIP, etc.) and optimize the inspection parameters.

(5) Safe operation

It is prohibited to adjust the camera focus at will, and it must be operated by trained personnel.

6. Common faults and solutions

Fault phenomenon Possible cause Solution

Blurred image/uneven brightness Lens contamination/aging of light source/focus offset Clean the lens, replace the light source, and recalibrate the focus

False alarm rate is too high Detection threshold is set too strictly/light source angle is not appropriate Optimize algorithm parameters and adjust light source angle

Transmission track is stuck Foreign objects on the track/sensor failure Clean the track and check the photoelectric sensor

Software crash/no response Insufficient memory/program conflict Restart the software, release memory, and update the version

Communication failure (MES/PLC) Loose network cable/protocol configuration error Check network connection and reconfigure communication protocol

7. Maintenance method

(1) Daily maintenance

Clean the lens and light source surface (use dust-free cloth + alcohol).

Check whether the transmission track is smooth and remove residual tin slag.

(2) Weekly maintenance

Calibrate light intensity and white balance.

Back up detection program and system parameters.

(3) Monthly/quarterly maintenance

Check whether the camera fixing screws are loose.

Clean or replace the heat dissipation filter
