OEM Ai Vision Cap Inspection System Machine for Edibel Oil Bottle Closures

Cooking oil is an indispensable seasoning for cooking and cooking in human daily life. In recent years, many large bottles of edible oil, soy sauce and other bottles have used combined caps. Such caps can effectively avoid the waste of edible oil. At the same time, the packaging of edible oil is an important part of food safety. Many manufacturers of combined oil caps have gradually increased their inspection efforts on the appearance quality of the combined caps. However, traditional manual inspections cannot achieve good results. The visual fatigue of the inspection and the factors of objective judgment have caused the final inspection effect to be inaccurate, which greatly affects the production efficiency of the production line. For the special structure of the combined cap, Keye Technology has customized a set of inspection programs for the combined oil cap.

Cooking oil bottle caps

Inspection Principle

Through the feeding and handing equipment, the caps are transferred to specific stations in a stable and orderly manner, and then the high-pixel sample images taken by industrial cameras are transferred to the image processing software. After comparing and analyzing the standardized samples, the products are judged as good and defective, and the corresponding control is controlled. The pneumatic components will reject defective products, and finally collect 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 defect rate.

Inspection Details

The whole system adopt 10 sets of high-pixel industrial cameras and high-performance stroboscopic light sources to conduct a full range of visual inspections for the appearance defects of smart cover products. The inspection speed is 300/min. The equipment can realize 7*24 hours of operation. , The unqualified products can be automatically rejected online.

The complete system includes mechanical parts, visual electronic hardware and inspection system software, which can be deployed independently on the customer site for use, and can be connected to the production equipment of the upper and lower processes according to the specific production needs of the customers.

Inspection Standard

In actual testing, due to the critical fluctuation state of certain testing item data affecting the judgment, it will cause a certain probability of product misdetection, which can be adjusted through the parameter setting of the system software to achieve the actual performance..

Camera working principle

Front area detection: The product passes through the adsorption conveyor belt, and a set of industrial cameras are placed on the top to match the vision

The light source is used to collect the front image of the product for analysis and processing.

Outside area detection: Taking into account the structural characteristics of the product, 4 sets of cameras are required to form the side detection of the ring.

Combined with the use of the visual light source, the imaging does not interfere with each other, and the system analysis and processing are performed after the image is collected.

Internal area detection: Taking into account the structural characteristics of the product, 4 sets of cameras are required to form the side detection of the ring.

Combined with the use of the visual light source, the imaging does not interfere with each other, and the system analysis and processing are performed after the image is collected.

Concave area detection: the product is output with the front side (brand side) upwards, guided into the glass turntable

Later, the concave angle of view was opened, and a set of industrial cameras were installed below to cooperate with the use of visual light sources to collect products.Analyze and process the concave image of the product.

The system needs to be maintained and cleaned regularly during use (such as conveyor belt cleaning, camera cleaning, etc.). After the finished product is tested, it can realize the counting function, and the counting accuracy is in the range of N to (N+5).
