Embodiment 1

[0049] Example 1: Using dual cameras combined with a bottom light source to detect foreign objects in infusion bottles

[0050] The detection system includes an intermittent rotating device, which is in the shape of a disc or a ring, and an upper pressing device and a lower pressing device that cooperate with each other are provided on the upper surface of the intermittent rotating device, and a first and the second two friction wheels, the two friction wheels are in the same plane as the lower pressing device, the rotation shafts of the two friction wheels are connected with servo motors, and the detection system also includes two cameras, The two cameras are connected to the computer, and the extension lines of the lenses of the two cameras intersect at one point. As the shooting station of the infusion bottle to be detected, a bottom light source is provided below the shooting station.

[0051] The detection process is as follows: the infusion bottle to be detected is plac...

Embodiment 2

[0052] Example 2: Using dual cameras combined with bottom light or backlight light source to detect foreign matter in the infusion bottle (bottom light source and backlight light source are irradiated alternately)

[0053] The detection system is based on the detection system of Embodiment 1. The side of the shooting station is also provided with a backlight source (the backlight source and the camera using the light source are arranged on different sides of the shooting station), and the bottom light source and the backlight light source are connected to the light source. controller.

[0054] The detection process is as follows: the infusion bottle to be detected is placed between the upper and lower compression devices through the corresponding transmission equipment, and is compressed by the upper and lower compression devices. When the intermittent rotation device carries the infusion bottle to be detected and reaches the first When the friction wheel is at the correspondi...

Embodiment 3

[0055] Example 3: Using dual cameras combined with bottom light and backlight light source to detect foreign matter in the infusion bottle (both light source and backlight light source are irradiated at the same time)

[0056] The detection system is the same as that of Example 2.

[0057]The detection process is as follows: the infusion bottle to be detected is placed between the upper and lower compression devices through the corresponding transmission equipment, and is compressed by the upper and lower compression devices. When the intermittent rotation device carries the infusion bottle to be detected and reaches the first When the friction wheel is at the corresponding position, the infusion bottle to be detected is rotated and accelerated through the first friction wheel, and when the intermittent rotation device carries the infusion bottle to be detected to the position corresponding to the second friction wheel, the infusion liquid to be detected is rotated through the ...

Abstract

The invention relates to a detection method and a detection system for foreign matters in an infusion bottle. The detection method comprises the following steps of: rotating a to-be-detected infusion bottle; photographing the bottle by utilizing a camera so as to obtain a multi-frame image; processing the image to obtain feature information of blocks in the bottle; removing the blocks formed by interferences of bubbles and lights; and comparing the feature information of the residual blocks with a detection standard, and judging whether the foreign matters exist, so as to judge whether the infusion bottle is qualified. The detection system comprises an intermittent rotating device and the camera, wherein upper compression devices and lower compression devices for fixing the relative positions of the to-be-detected infusion bottle and the intermittent rotating device are arranged on the intermittent rotating device, and friction wheels for driving the upper compression devices and the lower compression devices to rotate are arranged at the outer side of the intermittent rotating device. By utilizing the detection method and the detection system, the automatic detection on the foreign matters in the infusion bottle can be realized, and the problems of low efficiency, high labor intensity, easiness in generation of quality fluctuation and the like in the conventional detection method are solved; a reliable detection result can be obtained, and the export quality of products is effectively guaranteed.

Description

technical field [0001] The invention relates to a detection method and a detection system for foreign matter in an infusion bottle, which belongs to the technical field of detection and is mainly used for on-line detection of automatic production lines such as food and medicine. Background technique [0002] Medical infusion bottles have very high requirements on the cleanliness of the liquid in the bottle, but due to the production process or production environment, the finished infusion may be mixed with tiny foreign objects such as glass chips, aluminum chips, rubber chips, hair, fibers or insoluble drugs . The particles of these foreign bodies are small, and may enter the human body along with the infusion during intravenous infusion, causing blood vessel blockage, resulting in cystic phenomenon, and seriously endangering the life and health of patients. [0003] According to the provisions of the Chinese Pharmacopoeia, in the production process of infusion bottles, the...
