PET Preform Bottle Appearance Inspection Equipment with Good Product Collect Function

Wide-mouth PET bottle embryos appearance defect detection equipment

Technical standards

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.
