Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art based on this application are within the protection scope of the present utility model.

[0018] To address the issue of manually opening an inspection port to check for "white spots" during powder material mixing, which is inefficient and carries the risk of foreign matter falling into the mixture, this invention provides a mixing system.

[0019] In this embodiment of the utility model, a mixing system is provided, see [link to relevant documentation]. Figure 1a and Figure 1b The system includes: a mixing bin 1, a feeding port 2, a discharging port 3, a camera air blowing device 4, a high-definition camera group 5, a paddle 6, a flash device 7, and a display device. The display device is electrically connected to the high-definition camera group 5 and the flash device 7 respectively; The high-definition camera group 5 is installed on the top of the mixing hopper 1; The blade 6 is disposed inside the mixing bin 1 and located at the bottom; the shooting range of the high-definition camera group 5 includes the material-facing surface of the blade 6; The outlet of the camera air blowing device 4 faces the high-definition camera group 5.

[0020] In this embodiment of the invention, the mixing silo 1 can be a drum. The discharge port 2 can include one or more, and in actual use, these ports can be located at the top of the mixing silo 1. In one case, the mixing system in this embodiment is applied to the mixing of powder materials; specifically, one or more powders can be mixed, therefore, the one or more discharge ports can be used to discharge different raw materials respectively. In actual use, the discharge port 3 can be located at the bottom or side wall of the mixing silo 1, through which the mixed powder can be output. In practical use, the feeding port 2 and the discharging port 3 may also include a feeding switch and a discharging switch, respectively. Furthermore, the feeding switch and the discharging switch can be electrically connected to the display device. The opening and closing of the feeding switch and the discharging switch can be controlled by the control module in the display device. In one example, the display device includes an adaptive image enhancement processing module. The aforementioned control module can be the adaptive image enhancement processing module. The adaptive image enhancement processing module can be a chip or processor, such as a GPU (Graphics Processing Unit) or a CPU (Central Processing Unit).

[0021] In this embodiment, the high-definition camera group 5 is disposed on the top of the mixing hopper 1, and the display device is electrically connected to the high-definition camera group 5 and the flash device 7, respectively. This allows the display device to control the camera to acquire images inside the mixing hopper 1, thereby enabling the identification of "white spots" based on the acquired images. In one example, the display device can be electrically connected to another display device, allowing the display to show the images acquired by the high-definition camera group 5. This facilitates the operator's identification of "white spots" based on the acquired images. In another example, the display device can process the acquired images and automatically identify "white spots" based on the processed images. Specifically, the display device can automatically identify "white spots" using a pre-trained network model. The adaptive image processing module is electrically connected to the high-definition camera group 5 and the flash device 7, allowing the display device to control the high-definition camera group 5 to acquire images while simultaneously controlling the flash to illuminate, thereby improving the quality of the acquired images and facilitating the identification of "white spots" based on the acquired images. In one example, the high-definition camera group 5 can be an omnidirectional camera group.

[0022] In this embodiment of the present invention, the blade 6 is disposed inside the mixing bin 1 and located at the bottom; the shooting range of the high-definition camera group 5 includes the material-facing surface of the blade 6, so the high-definition camera group 5 can also capture images of the blade 6, thereby identifying the wear condition of the blade 6 through the captured images, which facilitates timely maintenance and replacement of the blade 6 by the operator.

[0023] As can be seen, the present invention allows for the installation of a camera on the top of the mixing hopper of the mixing system. This camera is electrically connected to a display device, enabling the acquisition of images inside the mixing hopper via a high-definition camera array. The high-definition camera then transmits the images to the display device for display. This allows for the acquisition of images inside the mixing hopper without opening it, thus enabling the determination of the presence of white spots. This not only improves detection efficiency but also prevents the risk of foreign objects falling in due to opening the mixing hopper.

[0024] In one possible implementation, the system further includes: a light strip; the light strip is ring-shaped and disposed on the inner wall of the mixing hopper 1, located at the top. In this embodiment of the invention, the light strip can be an LED (light-emitting diode) light source. The light strip facilitates the acquisition or observation of images inside the mixing hopper 1. In one example, an observation window can also be provided at the top of the mixing hopper 1, facilitating manual observation in emergency situations, such as when a camera malfunctions. In one example, the observation window can be a recessed observation window with a diameter of 50mm and a transparent cover. In another example, the light strip is a ring-shaped LED cold light source with a color temperature of 6500K and a width of 12mm, capturing images of the material surface at the transparent observation window of the mixing hopper 1, ensuring black-and-white contrast and clarity.

[0025] In one possible implementation, the system further includes: a light source air blowing device; the light source air blowing device includes a plurality of air blowing nozzles; the plurality of air blowing nozzles are directed toward the light strip. By directing the air blowing nozzles toward the light strip, it is easier to remove adhering substances, such as dust, from the surface of the light strip. This eliminates the need for manual cleaning, improving practicality and convenience. In one example, the light source air blowing device includes 12 air blowing nozzles, and the 12 air blowing nozzles are directed toward the light strip.

[0026] In one possible implementation, the drive module of the paddle 6 is also electrically connected to the display device. By connecting the drive module of the paddle 6 to the display device, the control module in the display device can control the rotation of the paddle 6, thereby controlling the operation of the mixing machine to ensure that no angle of the hopper bottom is obstructed by the paddle 6, and that all material-facing surfaces of the paddle 6 can be recorded. For example, the display device can send a signal to make the mixing paddle 6 rotate at a low speed. Through multiple image acquisitions, images of all positions in the mixing hopper 1 can be acquired, ensuring that all inner walls of the mixing hopper 1 are not obstructed by the paddle 6. Simultaneously, images of the paddle 6 can be acquired to detect the wear condition of the paddle 6. In one example, the display device includes an adaptive image enhancement processing module, which can be the control module. This adaptive image enhancement processing module can be a chip or processor, such as a GPU (Graphics Processing Unit) or a CPU (Central Processing Unit).

[0027] In one possible implementation, the inlet of the camera air blowing device 4 is connected to a compressed air pipeline. This allows the camera to be cleaned using compressed air via the camera air blowing device 4, ensuring image quality. Simultaneously, in practical use, blowing air onto the camera via the camera air blowing device 4 can also cool it, thus helping the camera operate in high-temperature environments. In another possible implementation, the high-definition camera assembly 5 includes a dust cover; the driving module of the dust cover is electrically connected to the display device. Through the electrical connection between the driving module of the dust cover and the display device, the opening and closing of the dust cover can be controlled by a control module in the display device, allowing the dust cover to be opened when image acquisition is needed and closed when acquisition is not required. In one example, the display device includes an adaptive image enhancement processing module, and the aforementioned control module can be this adaptive image enhancement processing module. This adaptive image enhancement processing module can be a chip or processor, such as a GPU (Graphics Processing Unit) or a CPU (Central Processing Unit). In one possible implementation, the system further includes a cleaning universal head; the inlet of the cleaning universal head is connected to a compressed air pipe or a water pipe. The cleaning universal head can utilize compressed air or water to clean the interior of the mixing chamber 1 and the impeller 6, etc. In one example, during image acquisition, the dust cover and camera air blowing device 4 can be opened to clean the environment and camera. After this cleaning, the high-definition camera group 5 begins operation. The omnidirectional camera group enables all-around image capture, while the flash and cooling device work together to prevent the equipment from overheating.

[0028] In one possible implementation, the inner wall of the impeller 6 and / or the mixing hopper 1 is coated. In another possible implementation, the system further includes a bottom cleaning device. The high-definition camera group 5 can also detect the coating on the inner wall of the impeller 6 or the mixing hopper 1. Specifically, during wear detection of the inner wall of the impeller 6 and / or the mixing hopper 1, after the mixing process is completed and before material is added, the high-definition camera group 5 begins to detect wear on the inner wall of the impeller 6 and / or the mixing hopper 1. The discharge port 2 is opened, and the universal nozzle of the bottom cleaning device is used to clean the mixing hopper 1 and the impeller 6 using high-pressure airflow or high-pressure water flow. After cleaning, detection is performed. Specifically, for the small amount of dust and material interference remaining inside the mixing equipment, dynamic light source adjustment and anti-interference algorithms, such as adaptive threshold segmentation, can be used to reduce misjudgments. The wear condition of the facilities within mixing silo 1 is assessed and confirmed through visual inspection. A signal is sent to cause the mixing paddle 6 to rotate at low speed to ensure that the paddle 6 does not obstruct any view of the inner walls of mixing silo 1, while simultaneously detecting the wear condition of the paddle 6. The model outputs the damage type, such as "crack," "stripping," or "wear," along with its location coordinates. False detections are filtered out based on a confidence threshold (>95%). After wear detection is complete, the system discharges the material. If any abnormality occurs, the system alarms and suspends equipment operation.

[0029] In one possible implementation, the system further includes a rapid dust collection device; the rapid dust collection device is connected to the top of the mixing silo 1. Dust collection can be performed first when image acquisition is required. Specifically, the rapid dust collection device can be a cyclone separator, etc. In one example, when performing image acquisition, dust collection can be performed first by activating the rapid dust collection device to quickly collect suspended dust in the air after mixing for approximately 30 seconds; then image acquisition is performed by photographing the material in the mixing silo 1 to check for "white spots" on the material. In one example, the high-definition camera group 5 used in this embodiment can be an industrial camera, such as a monochrome camera with a resolution ≥8MP, combined with a ring-shaped LED cold light source and a color temperature of 6500K, to capture images of the material surface at the transparent window of the mixing silo 1, ensuring clear black and white contrast. Therefore, the collected graphics can be used to: determine the uniformity of material mixing, and determine whether there are "white spots" in the mixed material; determine the wear of mechanical structure coating, and determine whether there is wear on the blades 6 or the coating; optimize the mixing time, and if uneven mixing is detected, the blades 6 can be controlled to continue mixing.

[0030] To illustrate the superiority of the present invention, the following description, in conjunction with the automated detection process achievable through embodiments of the present invention, will further illustrate this advantage.

[0031] In this embodiment of the invention, the high-definition camera group 5 can capture images of the interior of the mixing silo 1 by means of image acquisition. After image capture, a record is automatically generated, including relevant data such as application function, application time, and material ratio. Initially, images of relevant mixing "white spots" and equipment wear are input, and through self-learning, relevant situations are identified. Abnormal scenes can also be automatically recorded during use. Through continuous algorithm iteration, a recognition accuracy rate of over 95% is ultimately achieved.

[0032] Specifically, the uniformity of mixing and the optimization of mixing time: After the mixing equipment completes the mixing work, the visual inspection equipment automatically starts the uniformity detection. Among them, the running time T0; T0=f(D1 / D2,ρ1 / ρ2,H); (D1 / D2: particle size ratio, ρ1 / ρ2: density ratio, H: historical mixing efficiency data, model training data: training 50 batches of mixing records (including successful / failed cases). (1) Dust collection: turn on the rapid dust collection device to quickly collect the suspended dust in the air after mixing for about 30s; (2) Image acquisition: take pictures of the material in mixing silo 1 and check the "white spot" phenomenon of the material: use an industrial camera (black and white camera, resolution ≥8MP) with a ring LED cold light source (color temperature 6500K) to collect the material surface image at the transparent window of mixing silo 1 to ensure clear black and white contrast; Parameter settings: Grayscale range for black areas: 0-50 (8-bit); Grayscale range for white areas: 200-255 (8-bit). White spot detection threshold: Area of ​​consecutive pixels > 0.1mm 2 And the grayscale value is ≥200; Hierarchical gridding analysis: The image is divided into a 5×5 grid (25 detection units), and the area ratio of white points in each unit is calculated; Uniformity indicators: Standard deviation of white spot percentage across the entire grid ≤ 3%; maximum / minimum unit white spot area ratio ≤ 2:1. If no white spots are detected, the system continues to run and records the mixing run time T0; if no white spots are detected in 5 consecutive batches of mixing (SD ≤ 3%), the current mixing time T0 can be set as the new baseline time (T_base), and subsequent batches will continue to be optimized starting from T_base, with a compression coefficient of x; T_base = T0 × (1 - x%), (compressing x% each time); if white spots appear in a batch after optimization and compression (SD > 3%), immediately restore to the previous effective time, freeze the compression operation for 3 batches, and reduce the compression coefficient x. Optimization iteration: After five consecutive batches without white spots following time compression, record T0 and start a new round of optimization. If white spots are detected (SD>3%), compensate for the mixing time according to the grading standard (ΔT=k×T0). Grading standards: Mild unevenness: SD∈(3%,5%) (white spots are scattered, with slight local clustering) compensation coefficient k=0.1; Moderate unevenness: SD∈(5%,10%) (white spots are in patches or obvious bright spots appear) compensation coefficient k=0.2; Severe unevenness: SD>10% (large unmixed areas) compensation coefficient k=0.3, and manual verification is required. After remixing, image acquisition is performed again, and the cycle continues until the standard is met or the forced termination condition is met; ① Standard termination: SD≤3% after compensation mixing, stop immediately and record successful data; ② Forced termination: (a) If the standard is not met after 3 consecutive compensations, if the same batch has been compensated and mixed, the subsequent ΔT will decrease in gradient (e.g., the second compensation coefficient k=0.05); (b) The cumulative mixing time exceeds 1.5 times the initial time (alarm is triggered and the case is handed over to manual processing).

[0033] AI (Artificial Intelligence) optimization logic: Data feedback: The results of each mixing and each compensation mixing are input into the reinforcement learning model to optimize the initial values ​​of the running time T0 and the compensation coefficient k; Dynamic adjustment: The model learns the correlation between different material characteristics (such as the density ratio of black and white powder) and the compensation effect based on historical data.

[0034] The visual inspection system in this embodiment of the invention can specifically identify wear and white spots, avoiding the risks of insufficient material mixing and the introduction of foreign objects due to equipment wear. Furthermore, AI visual inspection can be used to determine white spot data and optimize mixing parameters, thereby improving mixing time and increasing the output of the mixing equipment.

[0035] As can be seen, the present invention allows for the installation of a camera on the top of the mixing hopper of the mixing system. This camera is electrically connected to a display device, enabling the acquisition of images inside the mixing hopper via a high-definition camera array. The high-definition camera then transmits the images to the display device for display. This allows for the acquisition of images inside the mixing hopper without opening it, thus enabling the determination of the presence of white spots. This not only improves detection efficiency but also prevents the risk of foreign objects falling in due to opening the mixing hopper.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
