Product Background
PCB board visual inspection is mainly to find out the defects of
electronic components and printed circuits by visually inspecting
the characteristics of electronic components, which can help you
more easily detect the problem of incorrect gaps between
conductors. At the same time, visual inspection is generally used
in production. The early stage of the process allows everyone to
find defects and repair them in the early stage of production as
much as possible to ensure a high product qualification rate. With
the development and progress of modern industry, traditional
detection methods can no longer fully meet the requirements of
modern industrial production. For the measurement requirements of
mechanical parts, real-time, online, non-contact detection,
high-speed, and high-accuracy detection modes are the
characteristics of the current manufacturing industry.
Inspection principle&features
PCB circuit board AOI inspection equipment, based on optical
principles, uses image analysis to denoise, enhance, binarize and
other processing of images, and uses deep learning and automatic
control technology to comprehensively detect and process defects
encountered in production, and generate real-time generation Test
Report. Detectable items: mainly detect PCB scratches, exposed
copper, dirt, poor dyeing, and integrity detection of solder joints
and wrong orientation.
The detection process is as follows: after the product is in place,
the client device gives a trigger signal, the industrial camera
completes image acquisition, and the PCB board component
intelligent visual inspection system detects the detection content
(component (plug-in) mixing detection, whether there is a component
(plug-in) or not). Detection, component (plug-in) positive and
negative detection, component (plug-in) color detection, component
(plug-in) direction detection, wire color detection, terminal block
color detection, terminal block direction detection) for efficient
analysis and processing. And the processed results, output OK/NG
results to the client designated terminal, the overall detection
results are as follows.
| 1.Product inspection status: online dynamic inspection |
| 2.Product inspection speed: 30~200 pieces/min (depending on the
complexity of product graphics) |
| 3.Inspection items: appearance, tracking printed circuit, solder
joint inspection, electronic parts welding inspection |
| 4.Response time: ≤200m |
| 5.Quality control: customized according to customer requirements |
| 6.Detection form: realize high-speed, stable and precise operation |
| 7.System performance: Ability to adapt to lack of light, or
illumination, and changes in focal length |
| 8.Detection form: It can realize the detection of different
precision requirements of partitions |
Machining Process
The mechanical part is the core component of the system, which
carries all the transmission devices and electronic hardware
(industrial cameras, light sources, industrial computers, touch
screens, electrical boxes, etc.). The conveyor is controlled by a
servo motor, and the image capture is accurate. The equipment is
equipped with two defective product inlets to separate serious
defective products (such as drum bottom, oblique leather tip, etc.)
and general defective products.
