Description

Technical Field

[0001] This utility model relates to the field of paper box packaging technology, and more specifically, to a cigarette box packaging adhesive spraying detection device and system. Background Technology

[0002] During the carton packaging process, adhesive needs to be applied to the carton paper in the paper transport channel. After the adhesive is applied, the carton paper is pressed together by the cigarette cartons to complete the carton packaging.

[0003] In existing technologies, gluing mainly employs two methods: spraying and roller coating. However, both methods have certain drawbacks. For example, when using an automatic glue spraying method to apply glue to carton paper, the process is often hampered by factors such as air pressure, nozzle blockage, glue quality, and air bubbles, leading to occasional glue spraying difficulties. Roller coating, on the other hand, suffers from glue loss due to factors such as roller gaps and intermittent roller stoppage. This results in glue streaks and dots being lost on the carton paper, preventing the packaging from sticking and causing it to fall apart. Furthermore, these defects are often sporadic, sudden, and intermittent; once defective products enter the market, they harm consumer interests and negatively impact the company's reputation.

[0040] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0041] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0042] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0043] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0045] This utility model provides a device for detecting adhesive spraying on cigarette box packaging, as described in the following embodiment. Figures 1 to 3 As shown, this utility model embodiment provides a cigarette box packaging adhesive spraying detection device, including: a main unit 11, a display screen 12, an electrical control cabinet 13, and a detection component 14;

[0046] Both the display screen 12 and the detection component 14 are mounted on the host 11; furthermore, the host 11 and the display screen 14 are connected by a rocker arm.

[0047] The host 11 is connected to the electrical control cabinet 13 via communication.

[0048] Understandably, the detection device is installed as a single unit, making it compact, aesthetically pleasing, and convenient on-site, without adversely affecting the original structure or usage habits. The display screen 14 connects to the main unit via a rocker arm, further enhancing convenience. This device has upgrade potential, allowing for easy additions or subtractions to accommodate future defect detection. It operates without noise. Electrical installation complies with specifications (low-voltage switchgear and control equipment) and features comprehensive safety protection functions and measures. The design, manufacture, installation, and operation all comply with relevant industry standards and specifications of the People's Republic of China, as well as internationally accepted standards.

[0049] Furthermore, the detection component 14 includes: a support component 141, a guide rail component 142, a light source component 143, a probe component 144, and a photoelectric sensor 145.

[0050] The support assembly 141 is used to connect to the host 11 and to arrange the various components. The guide rail assembly 142 is used to convey the material 00. The light source assembly 143 is used to provide a light source. The probe assembly 144 is used to take pictures of the area where the adhesive is sprayed on the material 00. The photoelectric sensor 145 is used to sense the position of the material 00 and trigger a detection switch.

[0051] Specifically, the guide rail assembly 142 conveys material 00 from bottom to top, and the signal from the photoelectric sensor 145 is sent to the electrical control cabinet 13 via the host 11. The microcontroller in the electrical control cabinet 13 determines that material 00 is in place based on the synchronization signal from the photoelectric sensor 145. Next, it controls the light source assembly 143 to start, and simultaneously sends a start signal to the probe assembly 144. The probe assembly 144 acquires an image of the current adhesive application point of material 00. The image acquired by the probe assembly 144 is sent to the host 11 for image recognition to determine the adhesive application status of the material.

[0052] Specifically, the detection software in the host 11 identifies the image acquired by the probe component 11 and compares it with the stored image template. If the pattern, color, similarity (FIT), and image position coordinates (X, Y) are within the set tolerances, the glue dot is considered qualified; otherwise, it is considered unqualified.

[0053] Meanwhile, the software in host 11 uses a vision system to learn the individual differences and deviations between good products, and identifies products that differ from these differences as defective products—an intelligent detection tool. During intelligent learning, it automatically removes defective products, eliminates human error during learning, and automatically calculates and sets thresholds.

[0054] Finally, the main unit 11 sends a quality signal to the electrical control cabinet 13. Based on the quality signal, the electrical control cabinet 13 rejects any substandard material 00. Furthermore, it can also issue alarms for any abnormalities.

[0055] In one optional implementation, the host computer 11 can be a fanless, fanless CES-E series machine vision AI industrial-grade industrial control computer from Foxconn Technology Group Corporation of Taiwan. It is equipped with an 8th generation Intel Core i7-8700T CPU processor with six cores and eight threads, a CPU clock speed of 3.2GHz, dual solid-state drives (128GB + 1TB), 16GB of memory, and an imported high-speed image acquisition board. It boasts strong processing capabilities, stable and reliable performance, and can adapt to the processing needs of complex algorithms, facilitating hardware upgrades. The high-configuration solid-state drives ensure high reliability of the system software. The built-in gigabit network card features high communication speed and stable data transmission, providing open communication protocols to support the MES data acquisition system in collecting and integrating operational data from the detection equipment.

[0056] Furthermore, the support assembly 141 includes a support frame 1441, a base plate 1442, and a connecting arm 1443;

[0057] The base plate 1442 is connected to the bottom of the support frame 1441; one end of the connecting arm 1443 is connected to the top of the support frame 1442, and the other end is connected to the side of the main unit 11.

[0058] The guide rail assembly 142 is vertically connected to one side of the support frame 1441, and the guide rail assembly 142 drives the material 00 to move from bottom to top.

[0059] Furthermore, referring to Figures 4 to 6 As shown, the light source assembly 143 includes a first light source 1431 and a second light source 1432. The first light source 1431 and the second light source 1432 are respectively connected to one side of the oriented guide rail assembly 142 of the support assembly 141, and the first light source 1431 and the second light source 1432 are respectively located on both sides of the material 00.

[0060] Furthermore, both the first light source 1431 and the second light source 1432 are vertically elongated strip-shaped LED light sources;

[0061] The lengths of the first light source 1431 and the second light source 1432 are not less than the length of the adhesive spraying area of ​​the material 00 along the vertical direction.

[0062] Furthermore, both the first light source 1431 and the second light source 1432 are parallel to the material 00 and are located on the outside of the adhesive spraying area of ​​the material 00.

[0063] Furthermore, the light-emitting surfaces of the first light source 1431 and the second light source 1432 are flush with the edge of the material 00.

[0064] Understandably, since there are glue application points at both ends of material 00, it is necessary to illuminate each of these glue application points separately. (Refer to...) Figure 4As shown, the adhesive spraying area includes adhesive strips and adhesive dots. Positioning both the first light source 1431 and the second light source 1432 vertically ensures a bright and uniformly lit area, resulting in clear imaging and preventing misjudgments caused by uneven lighting. Attaching the first light source 1431 and the second light source 1432 to the edges of the material 00 provides ample illumination.

[0065] In one optional implementation, the first light source 1431 and the second light source 1432 can be 24V DC LED cold light sources. These feature high stability, low light decay (less than 15% light decay after 20,000 hours), and high brightness (90 lumens / watt). They are equipped with a high-precision constant current driver and variable brightness LED light source adjustment technology, allowing for optimal illumination brightness configuration based on different material grades. Simultaneously, time-sharing exposure technology is employed to minimize the impact of various reflective interferences, and brightness adjustment can be achieved via software. It exhibits good adaptability to various brands of materials, features a PWM soft constant-on mode, prevents flickering, and does not interfere with the normal work of on-site personnel. The overall layout is integrated and sealed, with a service life exceeding 100,000 hours, and the system light source and spare parts are provided for life.

[0066] Furthermore, the probe assembly 144 includes a first camera 1441 and a second camera 1442, which are respectively connected to one side of the directional guide rail assembly 142 of the support assembly 141, and the first camera 1441 and the second camera 1442 are respectively opposite to the glue spraying area of ​​the material 00.

[0067] Furthermore, both the first camera 1441 and the second camera 1442 are set perpendicular to the material 00;

[0068] The shooting holes of both the first camera 1441 and the second camera 1442 are pointed towards the material 00.

[0069] Understandably, the first camera 1441 and the second camera 1442 are used to acquire real-time images of the two glue spraying points. The first camera 1441 and the second camera 1442 need to be perpendicular to the material 00 and directly facing the glue spraying point to ensure that the acquired images are clear and free of deformation.

[0070] In one alternative implementation, a Hengda industrial camera with a resolution of 2 megapixels can be used. This high-speed industrial camera boasts a long lifespan, stable performance, strong anti-interference capabilities, and clear, spotless, and wavy imaging. The camera directly captures images, reducing false rejections caused by variations in light sources. To work efficiently with the camera, a Japanese Computar 6mm compact lens can also be used, capable of capturing the full resolution of a megapixel camera (≥5 megapixels), with low distortion (below 0.01%), while maintaining high contrast and clear images across the entire screen area.

[0071] Furthermore, the photoelectric sensor 145 is connected to the side of the support frame 141 near the guide rail assembly 142.

[0072] Based on the same inventive concept, this utility model also provides a cigarette box packaging adhesive spraying detection system, referring to... Figure 7 As shown, a cigarette box packaging adhesive spraying detection system includes: an integrated industrial control computer 21, a human-machine interface 22, a single-chip microcomputer 23, a camera 24, an LED light source 25, an alarm 26, a rejection mechanism 27, and a video camera 28.

[0073] The LED light source 25, alarm 26, rejection mechanism 27, and camera 28 are all electrically connected to the microcontroller 23.

[0074] It should be noted that the integrated industrial control computer 21 is located inside the host 11, the microcontroller 23 is located inside the electrical control cabinet 13, and the display screen 12 is used to display the human-machine interface 22. The camera 24 is used in the probe assembly 144, and the LED light source 25 is used in the light source assembly 143.

[0075] It should be noted that the rejection mechanism 27 is a device that automatically identifies and rejects non-conforming materials in real time when the system detects them. Additionally, the system has an alarm 26, which provides an alarm notification during rejection and simultaneously outputs an alarm and shutdown signal when continuous rejections occur (the number can be preset). This prompts operators to promptly check the product quality status and prevent the quality defects from escalating. The rejection mechanism of this system has manual / automatic buttons for easy on-site equipment debugging.

[0076] The integrated industrial computer 21 communicates with the single-chip microcomputer 23;

[0077] The detection software in the all-in-one industrial computer 21 is capable of intelligent self-learning. Using images of adhesive dots on paperboard during production as training data, it continuously and automatically adjusts detection parameters to achieve stable and accurate detection. This reduces the need for manual parameter adjustments and lowers the professional requirements for maintenance. The detection software tools include pattern positioning detection, line positioning detection, pattern matching detection, warping detection, surface defect detection, and surface grayscale detection. Various defects can be flexibly detected using the software's tools. It can effectively detect a wide range of defects.

[0078] Furthermore, the system features flexible statistical analysis. During operation, the detection device provides various defect statistics tables and ratio comparisons for each brand and shift, based on process requirements, including output, rejection rate, and defect information. This allows for the determination of the weight of each defect, facilitating analysis of its causes. It can automatically store single-channel bad smoke images and bad smoke images from all channels, according to settings. It also records the date and time of bad smoke image generation in detail, facilitating quality tracking and analysis. The data can be stored long-term on a 1TB solid-state drive, with data rolling over (date period can be manually set).

[0079] The integrated industrial computer 21 is electrically connected to the human-machine interface 22.

[0080] The camera 24 is electrically connected to the integrated industrial computer 21 and the microcontroller 23.

[0081] Furthermore, camera 24 is electrically connected to integrated industrial computer 31 via network cable and Ethernet port. The industrial Ethernet interface provides an open communication protocol for flexible and convenient function expansion, and can be integrated with data from material handling systems. It can also perform data acquisition for data acquisition systems.

[0082] In summary, the cigarette box packaging adhesive spraying detection device and system provided by this utility model achieves at least the following beneficial effects:

[0083] In the embodiments provided by this utility model, photoelectric sensors are used to locate materials during transportation. The probe assembly captures images of the glue spraying areas on the left and right transverse ends and the long side of the material, and sends them to the host for analysis and processing. This detects potential issues such as missing or misaligned glue dots, and then rejects, statistically analyzes, and issues alarms.
