Varnished floor cloth, also known as floor leather (not PVC plastic
floor), is a floor covering material that belongs to rubber and
plastic products. Plastic varnished floor cloth has the advantage
of light weight, flexibility, good mechanical strength, comfortable
foot feel, wear resistance, stain resistance, corrosion resistance,
heat insulation, sound insulation, moisture resistance, low water
absorption, good insulation, and self-extinguishing , Easy to
clean, simple construction, convenient maintenance, low price and
other advantages, it is widely used in a large number of civil
buildings and public places, factories and laboratories which need
high requirements for cleanliness. Many manufacturers will arrange
corresponding product detection after the completion of the
production of varnished cloth. However, in the traditional
detection scheme, the appearance quality of varnished cloth leather
should be detect by oblique visual inspection under scattered
sunlight or fluorescent light. This method is wasting too much
time, and there is no way to higher the production efficiency.
1. Whether there are cracks, fractures and delamination on the
surface of the floor leather, if there are any, the floor leather
can be judged as unqualified.
2. Whether there are wrinkle marks, bubble pollution spots and
pattern deformation phenomena, the ones that are not observed are
the first-class and first-class products; the ones that very slight
and not obvious are regarded as qualified.
3. Whether there are any missing patterns on the surface of the
4. Is there any defect in the transparent wear-resistant film layer
on the surface?
5. Whether there is any deviation in the surface multi-color
overprinting, and whether there are color differences in different
If have above defects but do not affect the overall appearance of
the product as qualified. Finally, the appearance quality of the
varnished cloth is determined based on the above judgments.
Before the floor leather leaves the factory for sale, the factory
that has conditions will also conduct the final outer packaging
detection on the already packaged floor leather to make sure that
there will be no problems in the final step of the product, such as
the detection of product name factory name, product mark, grade,
batch number, quality, length, etc,of each roll of packaging.
When the floor leather surface defect detection machine is in
normal production on the production line, the bright LED linear
light source uses the principle of transmission to illuminate the
surface of the product (for the floor leather product with thicker,
surface defect detection angle requirements, the reflective floor
is used), the line scan camera set up on the production line
performs real-time synchronous scanning, and the system passes the
defect image collected by the camera through the KVS image
processing unit for defect segmentation processing.
Due to the obvious difference between the gray scale of the flawed
image and the gray scale of the normal product, the AI artificial
intelligence algorithm is used to enable the system to find and
locate the flaws accurately , and effectively judge and classify
the flaws at the same time .
