Inspection principle
Daily chemical products have penetrated into all aspects of people’s lives. When people choose daily chemical products, they will choose their habitual product brands according to their habits. There are more and more cosmetics and detergent manufacturers in China who choose in-mold labelled plastic bottles to package their own products. In-mold labeling technology will be more and more widely used in cosmetics, detergents, daily chemical industries and other industries, and it will be more and more favored by consumers. After adopting the in-mold labeling technology for daily chemical products, the brand image and product display effect are improved.
Compared with self-adhesive labels, it reduces the off-label phenomenon and the waste rate, saves the cost of manual labeling, and improves production efficiency. Therefore, as an important part of the outer packaging of the product, the quality detection of the finished product is an important part of the production of product packaging.
However, in the production process, after the film is blow-molded, it cannot be detected separately. Therefore, in the production process, through the detection requirements of the external packaging, Keye Tech design a set of overall packaging detection programs to break through the tradition. Low detection efficiency, use AI vision detection technology to improve production efficiency.
Detecting products
PP in-mold cup products, used for daily chemical packaging, see actual samples for details.
Detection principle
Through the docking conveying device (the product needs to be output in a straight line with the mouth facing upwards, and the product spacing must be kept above the radius of the cup mouth), the products are transferred to a specific station in a stable and orderly manner,and then the high-pixel sample image taken by the industrial camera is transferred to the image processing software, and the standard sample is compared and analyzed to determine the good product and the defective product, and control the corresponding pneumatic to remove the defective products and finally collect the qualified products.
The software will open the sample comparison standard, and the production personnel on the customer site can control the comparison accuracy and choose the accuracy standard most suitable for their own production conditions, thereby controlling the product defect rate.
Detecting details
Our design plan adopts 14 sets of high-pixel industrial cameras and high-performance stroboscopic light sources to carry out a full range of visual detection for the appearance defects of the bottle body. The detection speed is 120 pieces per minute. The equipment can realize 7*24 hours of operation, and the unqualified products can be automatically rejected online.
The whole set of detecting equipment includes mechanical parts, visual electronic hardware and detecting system software. The entrance and exit of the detecting machine can be integrated with the on-site conveyor line (see the design drawings for details), and can be connected to the upstream and downstream production equipment according to the specific production needs of the customer.
System composition
(1) Mechanical part:
The mechanical part is the core component of the system, which carries all the transmission devices and electronic hardware (industrial cameras,
Light source, industrial computer, touch screen, electrical box, etc.).
The conveyor belt adopts a vacuum adsorption belt to adsorb and fix the sample on the surface of the belt without sliding, so that the picture can be accurately taken.
(2) Hardware part:
The hardware part includes camera, lens, light source, high-speed air valve, computer, touch screen and other electrical equipment, the overall logic control of the system is realized by the high-speed FPGA chip.
Images collected by real machine (see actual samples for details):
