Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0036] It should be noted that when a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intermediate mechanism at the same time.

[0037] The embodiments of the present application provide a visual alignment labeling device, including a feeding area, a picking area and a working area. The visual alignment labeling device further includes:

[0038] A conveying mechanism for presetting the material in any posture at any position in the feeding area and conveying it to the working area through the conveying mechanism for labeling;

[0039] A detection mechanism for collecting the image information of the working area and generating the position coordinates and pose information of the material;

[0040] The manipulator obtains the label from the picking area, moves to the position corresponding to the material in the working area according to the position coordinates, and rotates the label according to the attitude information, so that the projection of the label on the material completely coincides with the labeling area, and moves the label along the first direction to fit the labeling area.

[0041] The provided vision alignment labeling device collects the image information of the working area through the detection mechanism and generates the position coordinates and attitude information of the material, enabling the labeling device to adapt to products with various shapes and attitudes. The conveying mechanism can automatically convey the material from the feeding area to the working area without the need for precise placement of the material, reducing the dependence on manual intervention. The manipulator automatically adjusts the position and angle of the label according to the position and attitude information provided by the detection mechanism, realizing the precise fitting of the label and the labeling area, thereby reducing the labor cost and improving the overall production efficiency.

[0042] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0043] Please refer to Figures 1-9 , an embodiment of the present application provides a vision alignment labeling device 100, including a feeding area 10, a picking area 20, and a working area 30. The vision alignment labeling device further includes:

[0044] A conveying mechanism 50, which presets the material to be placed at any position in the feeding area 10 in any attitude and conveys it to the working area 30 through the conveying mechanism 50 for labeling;

[0045] A detection mechanism 60, which collects the image information of the working area 30 and generates the position coordinates 611a and attitude information 612a of the material;

[0046] A manipulator 70, which obtains the label from the picking area 20, moves to the position corresponding to the material in the working area 30 according to the position coordinates 611a, rotates the label according to the attitude information 612a, makes the projection of the label on the material completely coincide with the labeling area, and moves the label along the first direction F1 to fit the labeling area.

[0047] Specifically, the feeding area 10 provides an area for loading and positioning the material. The material can enter in any attitude and position, and the device is allowed to process materials with different shapes and sizes, improving the ability to handle diverse products and reducing the need for manual intervention. The picking area 20 stores the labels, and the manipulator 70 obtains the labels to be labeled from here. The automated picking process reduces the manual operation time, improves the labeling speed and efficiency, and at the same time reduces the possibility of operation errors.

[0048] Furthermore, the conveying mechanism 50 controllably conveys the materials in the feeding area 10 to the working area 30 in any posture, ensuring the stability and accuracy of the materials during the transmission process and providing a reliable material conveying basis for the subsequent labeling process. The detection mechanism 60 collects the image information of the working area 30 and generates the accurate position coordinates 611a and posture information 612a of the materials through visual analysis, providing real-time and accurate material position and posture data, which provides an accurate basis for the manipulator 70 to accurately adjust the position and angle of the label, thereby ensuring that the label completely coincides with the labeling area of the materials. The manipulator 70 operates the position and angle of the label according to the detected position and posture information 612a, ensures that the label completely coincides with the labeling area of the materials, and moves the label along the first direction F1 to fit with the labeling area, realizing a highly automated labeling process, reducing the dependence on manual operation, improving the consistency and accuracy of labeling, and thus enhancing the production efficiency and quality control level.

[0049] In summary, the materials can be preset in the feeding area 10 in any posture and position. The conveying mechanism 50 is started to convey the materials from the feeding area 10 to the working area 30. After the materials reach the working area 30, the detection mechanism 60 collects the image information of the working area 30 and generates the accurate position coordinates 611a and posture information 612a of the materials. The manipulator 70 obtains the label from the material taking area 20 according to the detected information and accurately adjusts the position and angle of the label.

[0050] The label moves along the first direction F1, completely coincides with the labeling area of the materials, and completes the labeling process.

[0051] In a specific embodiment, the labeling device further includes a frame 40, and the detection mechanism 60 and the manipulator 70 are respectively arranged on the frame 40;

[0052] The conveying mechanism 50 includes a bracket 51 and a conveyor belt 52 arranged on the bracket 51. The bracket 51 is arranged on the frame 40. The preset materials are placed at any position of the conveyor belt 52 in any posture and are conveyed to the working area 30 by the conveyor belt 52 for labeling.

[0053] Specifically, the frame 40 provides a support and installation platform, integrating the various components of the entire labeling device. It ensures that each component works stably and reliably, reduces the errors caused by movement and vibration, and enhances the overall stability and reliability of the labeling device. The bracket 51 on the detection mechanism 60 supports and fixes the conveyor belt 52, ensuring that the conveyor belt 52 is stable and reliable during operation. It ensures that the conveyor belt 52 does not shake or shift when conveying materials, guaranteeing the accuracy and reliability of material conveyance.

[0054] Further, the conveyor belt 52 is responsible for transporting the preset material from the feeding area 10 to the working area 30. A controllable material transfer platform is provided, and the material can be preset on the conveyor belt 52 in any posture and position, so as to adapt to different labeling requirements and changes in the material form.

[0055] In a specific embodiment, the conveying mechanism 50 further includes a backlight plate 53, which is arranged on the bracket 51 and located between the bracket 51 and the conveyor belt 52, and on the side close to the detection mechanism 60.

[0056] Specifically, the backlight plate 53 provides uniform background illumination, enhancing the contrast between the material and the background, so that the detection mechanism 60 can collect image information more accurately. By providing a contrast background, through its uniform surface reflection and backlight projection, the edges of the material are clearly displayed, enabling the detection mechanism 60 to capture the contour and position of the material more clearly.

[0057] Further, the backlight plate 53 is fixed on the bracket 51 to make it stable and immovable. Ensure the position of the backlight plate 53 to provide a consistent background contrast effect, avoiding affecting the stability and accuracy of image acquisition due to the position change of the backlight plate 53. When the material on the conveyor belt 52 passes through the backlight plate 53, the contrast background provided by the backlight plate 53 can make it easier for the detection mechanism 60 to identify the edges and position of the material, thereby improving the detection accuracy.

[0058] In a specific embodiment, the detection mechanism 60 includes a camera member 61 arranged on the frame 40, and the camera member 61 is located above the working area 30 in the vertical direction;

[0059] The camera member 61 includes a vision module 611 and an image acquisition module 612 which are connected to each other. Both the vision module 611 and the image acquisition module 612 are data-connected to the manipulator 70. The vision module 611 identifies the labeling area to generate the position coordinates 611a of the material, and the manipulator 70 moves to the position coordinates 611a;

[0060] The image acquisition module 612 scans the material to acquire the posture information 612a of the material. The manipulator 70 rotates the label according to the posture information 612a to correspond to the posture of the material, and the manipulator 70 moves the label along the first direction F1 to fit the labeling area.

[0061] Specifically, the imaging component 61 is an important part of the detection mechanism 60 and is responsible for collecting image information within the working area 30. Fixing the imaging component 61 on the frame 40 ensures its stability and accuracy, avoiding affecting the quality of image collection due to vibration or movement. The imaging component 61 vertically looks down at the working area 30, capable of comprehensively covering the entire working area 30 and capturing the overall view and details of the material. Providing higher image resolution and viewing angle coverage enables the detection mechanism 60 to accurately identify the position and posture of the material, improving the detection accuracy.

[0062] Furthermore, the vision module 611 is responsible for image processing and analysis, generating the position coordinates 611a of the material; the image acquisition module 612 is responsible for capturing image information and obtaining the posture information 612a of the material. Separating the image acquisition and processing functions improves the processing efficiency and accuracy, ensuring the accurate acquisition of the position and posture information 612a of the material. Through a data connection to the manipulator 70, the detection results are transmitted to the manipulator 70 in real time. Realizing real-time sharing and synchronization of data ensures that the manipulator 70 can adjust its position and posture according to the latest detection information, improving the labeling accuracy.

[0063] Still further, the vision module 611 identifies the labeling area on the material through image processing and generates its position coordinates 611a. Providing the accurate position of the labeling area provides an accurate moving target for the manipulator 70, ensuring that the label is attached to the correct position. The manipulator 70 moves above the labeling area according to the position coordinates 611a provided by the vision module 611. Precise positioning of the manipulator 70 enables the label to be accurately aligned with the labeling area, improving the accuracy and consistency of labeling.

[0064] The image acquisition module 612 scans the material to obtain its posture information 612a, such as changes in the tilt angle. This enables the imaging component 61 to comprehensively understand the posture of the material, providing a basis for the manipulator 70 to adjust the angle of the label and ensuring perfect adhesion of the label to the material surface. Subsequently, the manipulator 70 adjusts the angle of the label according to the posture information 612a of the material to make it consistent with the surface posture of the material. Ensuring that there are no bubbles or skews when the label adheres to the material surface improves the labeling quality and aesthetics. The manipulator 70 moves the label along a predetermined direction to make it adhere to the labeling area of the material.

[0065] In summary, the material is conveyed to the working area 30, and the imaging member 61 looks down at the working area 30 in the vertical direction. The image acquisition module 612 captures the image information of the material, and the vision module 611 processes the image, identifies the labeling area of the material, and generates the position coordinates 611a. The detection mechanism 60 transmits the position coordinates 611a of the material to the manipulator 70, and the manipulator 70 moves to the corresponding position. The image acquisition module 612 scans the material, obtains the attitude information 612a of the material, and transmits it to the manipulator 70. The manipulator 70 adjusts the angle of the label according to the attitude information 612a to make the label correspond to the material attitude. The manipulator 70 moves the label in the first direction F1 to make it adhere to the labeling area of the material, completing the labeling.

[0066] In a specific embodiment, the detection mechanism 60 further includes a light supplement member 62, the light supplement member 62 is disposed on the frame 40, the light supplement member 62 is provided with a through hole 621, and a part of the imaging member 61 extends into the through hole 621.

[0067] Specifically, the light supplement member 62 provides additional light sources to supplement the light in the detection area and improve the image quality. By increasing the additional illumination, the light supplement member 62 can reduce the problems of shadows and uneven light, enabling the detection mechanism 60 to capture clearer and higher-contrast images, and improving the accuracy of image processing and recognition. The light supplement member 62 is fixed on the frame 40 to provide a stable light source within the working area 30. Fixing the light supplement member 62 on the frame 40 ensures its stable position, avoids affecting the consistency of the light due to vibration or movement, and guarantees stable lighting conditions in the detection area all the time, improving the detection accuracy and reliability.

[0068] Furthermore, a through hole 621 is provided on the light supplement member 62 to enable a part of the imaging member 61 to extend into it, ensuring that the imaging member 61 can directly observe the detection area and at the same time benefit from the uniform light provided by the light supplement member 62. The design of the through hole 621 enables the imaging member 61 to be directly located at the middle position of the light source provided by the light supplement member 62, ensuring that the image collected by the imaging member 61 has uniform illumination, no obvious shadows or reflections, and improving the image quality and recognition accuracy. A part of the imaging member 61 extending into the through hole 621 enables the imaging member 61 to pass through the through hole 621 of the light supplement member 62 and directly look down at the detection area, thereby obtaining a clearer image. A part of the imaging member 61 extending into the through hole 621 places it in the best observation position, combined with the uniform light provided by the light supplement member 62, ensuring that the image collected by the imaging member 61 is clearer and more accurate, and improving the detection accuracy.

[0069] In a specific embodiment, the manipulator 70 includes a first slide rail 71 and a labeling assembly 72, the first slide rail 71 is disposed on the frame 40, and the labeling member 722 is rotatably connected to the first slide rail 71;

[0070] Define the direction from the material picking area 20 to the working area 30 as the second direction F2, and the first slide rail 71 is arranged along the second direction F2.

[0071] Specifically, the main structure of the manipulator 70 includes a first slide rail 71 and a labeling assembly 72. The first slide rail 71 is used to provide a moving path between the material picking area and the working area 30, and the labeling assembly 72 is used to perform the operations of picking and labeling the labels. The first slide rail 71 provides the moving route of the manipulator 70, enabling the manipulator 70 to move stably on a predetermined path. The labeling assembly 72 performs the operations of picking and labeling the labels to ensure that the labels can be accurately attached to the materials. The first slide rail 71 is fixed on the frame 40 to provide stable support and a moving path. Ensure the stability and accuracy of the slide rail, avoid errors caused by the instability of the slide rail, and improve the accuracy and consistency of labeling.

[0072] Furthermore, the labeling member 722 can move along the first slide rail 71 and at the same time has a rotating function, and can adjust the angle according to the posture of the material. The rotatable connection of the labeling member 722 to the slide rail allows the labeling member 722 to adjust the angle according to different postures of the material during the movement, improving the accuracy and adaptability of label attachment, and ensuring that the label can be accurately attached to the labeling area of the material. Define the direction from the material picking area 20 to the working area 30 as the second direction F2, clarify the direction from the material picking area 20 to the working area 30, and facilitate the layout and design of the slide rail and the manipulator 70. Make the movement path of the manipulator 70 clear, improve the standardization of equipment design and the simplicity of operation.

[0073] Still further, the first slide rail 71 is arranged along the direction from the material picking area 20 to the working area 30 to ensure that the manipulator 70 can move smoothly between these two areas. The setting direction of the slide rail is consistent with the direction from the material picking area to the working area 30, ensuring that the manipulator 70 can efficiently move from the material picking area 20 to the working area 30, improving work efficiency and operation coherence.

[0074] In a specific embodiment, the manipulator 70 further includes a second slide rail 73. The second slide rail 73 is arranged on the bracket 51 along a third direction F3 perpendicular to the second direction F2, and the labeling assembly 72 is on the second slide rail 73.

[0075] Specifically, a second slide rail 73 is added to the manipulator 70 to endow it with the ability to move in multiple directions. Adding the second slide rail 73 expands the degrees of freedom of movement of the manipulator 70, enabling it to move not only in the second direction F2 but also in the third direction F3, enhancing the flexibility and coverage of the manipulator 70 within the working area 30. The second slide rail 73 is arranged on the bracket 51, and its direction is perpendicular to the second direction F2, that is, the third direction F3. By arranging the second slide rail 73 in the third direction F3 perpendicular to the second direction F2, the manipulator 70 can move in two perpendicular directions, improving the flexibility and precision of operation. This allows for better adjustment of the position of the labeling component 72 to adapt to different positions and postures of the material.

[0076] Furthermore, the labeling component 72 is installed on the second slide rail 73 and can move along the second slide rail 73. Installing the labeling component 72 on the second slide rail 73 endows it with the ability to move in the third direction F3. This increases the operating range of the labeling component 72, enabling it to cover a larger working area 30, adapt to materials of different sizes and positions, and enhance the flexibility and efficiency of labeling.

[0077] In a specific embodiment, the labeling component 72 includes a third slide rail 721 and a labeling member 722. The third slide rail 721 is arranged on the second slide rail 73 along the first direction F1, and the labeling member 722 is rotatably connected to the third slide rail 721.

[0078] Specifically, the main structure of the labeling component 72 includes a third slide rail 721 and a labeling member 722. The third slide rail 721 provides a moving path for the labeling member 722, and the labeling member 722 is used to perform the operations of picking up and attaching labels. The combination of the third slide rail 721 and the labeling member 722 endows the labeling component 72 with the ability to move and position precisely, ensuring that the label can be attached to the material accurately and without error, improving the accuracy and efficiency of labeling. The third slide rail 721 is installed on the second slide rail 73 and is arranged along the first direction F1 (usually the vertical direction). This enables the labeling component 72 to move in the vertical direction, further expanding the degrees of freedom of movement of the labeling component 72, enabling it to more flexibly adapt to different positions and heights of the material, and improving the flexibility and adaptability of operation.

[0079] Furthermore, the labeling member 722 is installed on the third slide rail 721, can move along the third slide rail 721, and has a rotating function to adapt to the posture of the material. The rotatable connection between the labeling member 722 and the third slide rail 721 allows the labeling member 722 to adjust its angle according to the posture of the material during movement, ensuring that the label can be perfectly aligned with the labeling area of the material, and enhancing the accuracy and consistency of labeling.

[0080] In a specific embodiment, the labeling member 722 includes a rotating portion 722a and an adsorption portion 722b arranged in sequence. The adsorption portion 722b is provided at one end of the third slide rail 721 close to the conveying mechanism 50, and the rotating portion 722a is fixedly connected to the adsorption portion 722b to drive the rotation of the adsorption portion 722b.

[0081] Specifically, the labeling member 722 consists of two main parts: the rotating portion 722a and the adsorption portion 722b. The rotating portion 722a is responsible for rotational adjustment, and the adsorption portion 722b is responsible for grasping and placing labels. The design of the separation function enables the labeling member 722 to flexibly handle materials in different postures, improving the accuracy of label attachment. The rotating portion 722a enables the adsorption portion 722b to adapt to different angles, while the adsorption portion 722b ensures the firm grasping and precise placement of the labels. The adsorption portion 722b is located at one end of the third slide rail 721, close to the conveying mechanism 50, facilitating the picking up of labels directly above the materials on the conveyor belt 52. The position design of the adsorption portion 722b enables it to operate efficiently near the conveying mechanism 50, reducing the movement path and improving work efficiency. The position close to the conveying mechanism 50 ensures the quick picking up and attachment of labels, reducing the waiting time.

[0082] Furthermore, the rotating portion 722a is fixedly connected to the adsorption portion 722b, and the movement of the rotating portion 722a drives the adsorption portion 722b to perform rotational adjustment. The connection between the rotating portion 722a and the adsorption portion 722b enables the adsorption portion 722b to flexibly adjust the angle, adapt to various postures of the materials, and ensure that the labels can be accurately attached to the predetermined positions of the materials. The presence of the rotating portion 722a improves the adaptability and accuracy of labeling.

[0083] In a specific embodiment, the labeling device further includes a lifting mechanism 80. The lifting mechanism 80 is provided on one side of the frame 40 close to the conveying mechanism 50, and the output shaft of the lifting mechanism 80 is fixedly connected to the conveying mechanism 50 to drive the conveying mechanism 50 to move along the first direction F1.

[0084] Specifically, the lifting mechanism 80 is located at a position on the side of the frame 40 close to the conveying mechanism 50, facilitating access by operators and robotic automation systems to the conveyor belt 52 and related labeling devices. This position design ensures that the lifting mechanism 80 does not interfere with the normal operation of the conveyor belt 52 during operation and is convenient for operators to perform maintenance and adjustment. The lifting mechanism 80 is directly fixedly connected to the conveying mechanism 50 through its output shaft. This design enables the lifting mechanism 80 to lift and lower the conveying mechanism 50 along the first direction F1 through its movement.

[0085] Furthermore, the lifting mechanism 80 can adjust the height of the conveying mechanism 50 through the movement of its output shaft, enabling materials of different shapes and sizes to meet the scanning requirements of the detection mechanism 60. Through the lifting function of the lifting mechanism 80, it can ensure that the materials on the conveyor belt 52 are at the optimal height and position during the operation of the detection mechanism 60, thereby achieving a comprehensive and accurate scan of the materials. The presence of the lifting mechanism 80 ensures that the detection mechanism 60 can conduct a comprehensive scan over the entire surface of the material, regardless of the changes in the shape and height of the material. This design guarantees that the labeling device can maintain consistent detection accuracy and quality standards when processing materials of various shapes and sizes. By adjusting the height of the conveyor belt 52, it is possible to avoid partial scanning or omission caused by different material heights.

[0086] The above are only the embodiments of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all fall within the protection scope of the present application.
