Inspection principle
The defects of wide-mouth PET bottle embryos are mainly caused by
black spots, impurities, gaps, overlaps, cracks, scratches, holes,
bubbles, deformation, size and other defects in the production
process due to the incomplete production technology and mechanized
production line. , Wide-mouth PET bottle embryos are part of the
bottle, which is mainly processed by injection molding. Before
blowing the finished product, it must undergo strict product
appearance detection. Through equipment detection, problems in
production can be found in time and reminded It can improve the
quality of products and ensure the interests of consumers.
The PET bottle embryos defect detection machine produced by our
company can effectively detect various defects of the bottle
embryos, equipped with 10 sets of high-pixel industrial cameras to
comprehensively detect the appearance defects of the outer side of
the bottle embryos, the opening of the embryo and the bottom of the
embryo. After the system collects the sample image, the image
processing software is compared with the standardized sample to
determine the good product and the bad product. Good products are
detected and defective products are automatically eliminated
online, and the counting function can be realized after the
finished product is detected, and the counting accuracy rate is
100%. The software will open the sample comparison standard, and
the production personnel at the customer site can control the
comparison accuracy and select the most suitable accuracy standard
for their own production conditions, thereby controlling the defect
rate.
1. Four cameras are used for double stations around the bottle
embryo: because the product is made of PET, the four cameras are
divided into two stations, and each station is equipped with two
cameras and two sets of backlight sources to complete the detection
of the outer side of the bottle embryo, the detection content
includes black spots, bubbles, stains, and oil stains with color
difference.
2. Four cameras are used for the bottle embryo mouth: four
detection stations for the bottle embryo mouth, respectively to
detect the bottle embryo mouth, and the detection content includes
the lack of material, burrs, overlaps, stains and black spots in
the bottle embryo mouth.
3. The detection of the bottle embryo support ring adopts a camera
to detect the lack of material of the support ring.
4. The detection of the bottom of the bottle embryo uses a camera
to detect the black spots and voids at the bottom of the bottle
embryo.
