1.
Common Inspection Challenges of Appearance Defect Inspection 1.
Limitations of Manual Inspection Manual inspection can achieve accurate surface inspection, but for high-speed online processes, it is not only slow but also costly
.
2.
Material Surface Variations From low-contrast black rubber surfaces to highly reflective or transparent materials such as glass or plastic, there are significant differences in the surface properties of materials in different industries
.
3.
Defect type and location The different shapes and locations of surface defects pose serious challenges for 100% quality control
.
4.
Defects within geometric tolerances Due to the height/depth of some surface defects, defects smaller than the geometric tolerance cannot be detected
.
Second, the technical difficulties of surface appearance defect detection According to different classification standards, product surface defect detection can be divided into many categories: for example, according to the shape of the product, it can be divided into regular product surface defect detection and irregular product surface defect detection
.
According to the product, it can be divided into surface defect detection of metal parts and surface defect detection of plastic parts
.
According to the inspection requirements, it is mainly divided into full defect inspection and partial defect inspection
.
Although there are many types of surface appearance defect detection, in general, the problems existing in the current surface appearance defect detection mainly include the following aspects: 1.
Detecting product arcs and cylinders: defect detection is due to the definition of defects by different people Different, even if the same person is under different lighting conditions, the definition of the same defective product is different
.
Therefore, it is difficult to measure this defect specifically, and the detection of camber and cylinder is even more problematic.
Due to the influence of factors such as cameras and lenses, it is difficult to detect the cambers or cylinders at different positions on the surface.
defect
.
Some would suggest that the product could be turned, yes, but that would affect the detection speed, which is an important indicator of the viability of the equipment that customers care about
.
Since its establishment, Yingtaide has been committed to solving various automated vision solutions for customers
.
2.
Detect the inner wall and inner hole of the product: Due to the characteristics of the lens itself, it is difficult for visual inspection to detect the internal defects of the product, especially the internal defects of some slender parts
.
Difficulty does not mean that it cannot be solved.
After long-term experimental research, Shenzhen Yingtaide Technology Co.
, Ltd.
has made great achievements in detecting the inner wall of oil-free bearings, detecting needle rollers in needle roller bearings, and detecting internal thread defects of screws
.
At present, our visual inspection equipment can fully detect the internal defects of parts
.
3.
Detection of rubber parts: There are three main problems in the detection of rubber parts
.
One is that most of the rubber parts are black in color.
Black is easy to absorb light, and it is not easy to light up in visual inspection, which can easily lead to some defects that are missed
.
The second point is that because the rubber parts are large, the parts are irregular, and the detection of surface defects is difficult
.
Third, due to its own characteristics, it is often difficult for rubber parts to find internal cracks and particles without stretching
.
The above three points determine the difficulty of rubber parts inspection, which is why the use of visual inspection of rubber parts is currently limited
.
At present, the inspection of rubber parts is still a difficult point for our entire industry
.
At present, only large cracks and missing blocks can be detected, and the road to defect detection of rubber parts is still far away, and we need to continue our efforts
.

3D inspection solutions 1.
Automated non-contact inspection The non-contact 3D intelligent inspection system will not damage the surface material, can produce highly accurate and highly repeatable measurement data, and can match the online production speed
.
2.
Defect Recognition and Analysis The 3D intelligent inspection system has built-in anchoring and part matching functions to ensure that the same position of each part conveyed on the conveyor can be detected regardless of changes in part position
.
3.
Sub-micron-level high-resolution surface defect detection In order to obtain higher detection accuracy, please use metrology-level 3D technology (such as structured light scanning inspection) for sub-micron precision surface analysis
.
4.
Handling multiple types of surface materials The 3D intelligent inspection system provides a variety of exposure methods and data processing algorithms for handling reflective surfaces (such as small electronic parts) and low-contrast surfaces (such as tire surfaces and sidewalls)
.
The above points are the contents of appearance defect inspection introduced for you.
The equipment includes: optical screening machine, automatic inspection equipment, visual inspection equipment, optical image screening machine, CCD visual inspection equipment, industrial visual inspection, defect inspection equipment, high-speed online inspection equipment, machine vision inspection, non-standard inspection equipment, etc.
, if you need to use machine vision inspection technology in your industrial production line
