Problems solved by technology

[0003] In the production process of canned infusion bottles, unqualified and defective products will inevitably appear, which not only brings safety hazards, but also may affect product quality
The traditional manual light inspection method is difficult to guarantee the reliability and rapidity of detection, thus causing some unqualified products to flow into the market and causing damage to the corporate image
[0004] At present, the market is limited by hardware, and the general image acquisition system has poor resolution of colors. Although many domestic companies are committed to the research and development of light inspection machines, due to problems such as insufficient mechanical manufacturing technology and poor detection algorithms, the developed light In the process of detecting foreign objects, the detection machine has a high rate of missed detection and false detection, and repeated detection is required, which leads to low detection efficiency
Therefore, the prior art has the technical problems of low detection efficiency and low accuracy

Embodiment 1

[0055] figure 1 A schematic structural diagram of a defective sorting and rejecting device for filling infusion bottles 1038 provided by the present invention, such as figure 1 As mentioned above, the device includes: a light source, an industrial camera, a robotic arm 101 and a host computer 102, wherein,

[0056] The industrial camera and the robotic arm 101 are respectively connected to the host computer 102 through Gigabit Ethernet; the maximum transmission rate of the Gigabit Ethernet data interface can reach 1000Mb / s, which is much higher than the transmission rate of USB2.0 and 1394. The industrial camera in the invention is a variable magnification area array CCD color camera. CCD color camera integrates photoelectric conversion, charge storage, charge transfer, and signal reading. Using charge as a signal, it has the advantages of low power consumption, low voltage operation, and no lag. Whether it is static acquisition or dynamic acquisition, it can be obtained with...

Embodiment 2

[0068] On the basis of Example 1, after the detection of black foreign objects and white foreign objects is completed, Example 2 adds the following zero-degree incubator 201, spray box 202 and third industrial camera 203, wherein,

[0069] The zero-degree incubator 201 accommodates the infusion bottle 1038 to be detected. The zero-degree incubator 201 is a box-type structure, and its side is provided with a side cover that can be automatically opened and closed. When the mechanical arm 101 triggers the limit switch, the side cover drives the structure. Turn on the power to open the side cover, and the robotic arm 101 extends into the zero-degree incubator 201 to take out the infusion bottle 1038, and moves away from the zero-degree incubator 201. When the set position is reached, the limit switch is released and the side cover is closed. Specifically, the limit switch can be arranged on the slide rail where the carrying platform of the robotic arm 101 is located. When the carry...

Embodiment 3

[0077] Based on Embodiment 1 or 2 of the present invention, Embodiment 3 of the present invention is a method for detecting defective products in the production process of canned infusion bottles reasonably based on big data. More objective, precise and standardized. Effectively reduce the missed detection rate and false detection rate in the sorting and rejection of defective infusion bottles, thereby improving the accuracy of detection. Moreover, automated and intelligent detection can greatly improve the detection efficiency of the production line, greatly shorten the detection time, and save costs. The system is a high-speed online detection system integrating machine vision, precision machinery and real-time control. It mainly realizes the detection of bottle mouth breakage, the detection of contamination on the bottle mouth, the bottom of the bottle and the bottle wall, as well as the detection and rejection of residual liquid in the bottle. and other functions.

Abstract

The invention discloses a quality detection method, system and device for filling infusion bottle production, and the method comprises the steps: transferring a sample infusion bottle into a quality detection system through a mechanical arm, and obtaining sample image data outputted by a white foreign matter detection station and a black foreign matter detection station, extracting structural features of sample infusion bottles and quality features of the infusion bottles from the sample image data to serve as a first sample set; adding the first sample set into the current sample set, and adjusting parameters of an upper computer identification model; transferring the sample infusion bottles into the quality detection system again to obtain a second sample set, and adding the second sample set into the current sample set until a trained target model is obtained; and detecting the quality of the infusion bottle by using the target model. According to the embodiment of the invention, the capacity of the current sample set for training the model can be simply, automatically and quickly expanded, and more accurate training of the target model can be realized.

Description

technical field [0001] The invention relates to the technical field of product inspection, and more particularly to a quality inspection system for filling infusion bottle production. Background technique [0002] Before large infusion products are finalized and flow into the society, many links such as measurement, positioning, correction, and identification are involved. [0003] In the production process of canned infusion bottles, it is inevitable that unqualified defective products will appear, which not only brings hidden safety hazards, but also may affect product quality. The traditional manual light inspection method is difficult to ensure the reliability and rapidity of the inspection, which causes some substandard products to flow into the market and damages the corporate image. [0004] At present, the market is limited by hardware, and the general image acquisition system has poor color resolution. Although many domestic companies are committed to the research ...
