AI Automated Vision Inspection System Equipment For Drinking Straws

Product background:

The straw or drinking tube is a cylindrical, hollow plastic product. Its main function is to drink beverages and water in a cup, and it is also used to suck the bone marrow of some cooked animal long bones. At present, with the rapid development of computer and machine vision technology, a visual detection device replaces the manual observation method to detect the straw, but the detection light source and detection camera set by the existing visual detection device are mostly inconvenient after the fixing is completed. Adjusting its position cannot make the detection light source and the detection camera in the best detection distance and detection angle, which may cause a certain misjudgment of the visual detection device during detection, thereby reducing the detection efficiency of the visual detection device.

Inspection principle:

In view of the problems existing in the prior art, the purpose of the present invention is to provide a visual detection device for drinking straws, wherein the visual detection device for drinking straws is provided with an upper detection light source, an upper camera, a lower detection light source and a lower camera with The function of adjusting the distance between the tube and the material, and the upper and lower cameras also have the function of adjusting the inclination angle, so as to reduce the misjudgment rate of the visual inspection device, improve the detection accuracy and detection efficiency of the visual inspection device, and set the The upper cover and the lower cover are convenient to switch, which brings great convenience to the adjustment of the upper detection light source, the upper camera, the lower detection light source and the lower camera.

Inspection details:

The inspection machine adopts multiple sets of high-pixel industrial cameras and high-performance stroboscopic light sources to carry out omni-directional visual inspections for product appearance defects. The equipment can realize 7*24 hours of all-weather operation, and it can be online automatically. Eliminate substandard products.The whole set of inspection equipment includes mechanical, visual electronic hardware and inspection system software. The entrance and exit of the equipment are reserved for docking positions to facilitate on-site operations.

1. In actual detection, due to the influence of the critical fluctuation state of the data of some detection items, it will lead to a certain probability.

If the product is falsely detected, it can be adjusted through the parameter setting of the system software to achieve the actual effect.

2. Black spots, stains, impurities, hair and other defect features (different colors), the gray value contrast difference corresponding to the detection index should be greater than 40 (it can be understood as: placing the sample at an arm distance, about 30cm or more, can be Defect features seen by visual inspection) can be effectively detected. If the sample has transparent oil stains or light-colored black spots, and the gray value contrast difference is low (below 40), the detection effect cannot be achieved.

3. The horizontal direction of the straw belt is the blind area of the camera's field of view, so the defect features at this position cannot collect images for input.

Line recognition, but this position is relatively narrow, the vertical distance is about 1.0mm.
