For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0059] At present, the application of battery devices is becoming more and more extensive. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0060] During the production process of battery devices, labels need to be attached to the battery devices. Labels can provide necessary product information and safety warnings, and also play an important role in brand promotion, traceability management, and regulatory compliance.

[0061] The traditional labeling process mostly involves manual label removal and label affixing, and finally manual smoothing of the label and exhaust of the air at the bottom of the label to complete the labeling action. Manual production efficiency is low and the quality is not high. Wrinkles, folded corners, bubbles and wrong positions will appear in the labeling process.

[0062] There are also some related technologies that use mechanical equipment to affix labels. However, due to the possibility of abnormal conditions in the mechanical equipment (such as loose mechanical connections), the structure that directly affixes labels will be offset when the first piece is processed at the beginning of the shift, making it difficult to perform accurate labeling operations.

[0063] Therefore, how to improve the efficiency and accuracy of labeling is an important issue in battery production and processing.

[0064] In view of this, the present application provides a battery labeling device, which utilizes a visual recognition device to identify the labeling area, and adopts a driving device to drive the labeling device to perform labeling to realize the automation of labeling, so as to improve the labeling efficiency. At the same time, it can also detect the coordinate information of the visual recognition device itself when it is in the initial position, thereby reducing the possibility of the visual recognition device still performing the labeling operation after the deviation occurs, and improving the accuracy of labeling.

[0065] The following is combined with Figure 1-7 The battery labeling device 100 provided in an embodiment of the present application is described and introduced.

[0066] Combined with Figure 1 and attached Figure 2As shown, an embodiment of the present application provides a battery labeling device 100, including a frame 10, a driving device 20, a labeling device 30 and a visual recognition device 40, wherein the driving device 20 is installed on the frame 10; the labeling device 30 is connected to the driving device 20, and is configured to move between a first initial position and a labeling position under the drive of the driving device 20; the visual recognition device 40 is connected to the driving device 20 or the labeling device 30, and moves synchronously with the labeling device 30, when the labeling device 30 is in the first initial position, the visual recognition device 40 is in a second initial position different from the first initial position, and the visual recognition device 40 is configured to be able to detect its own coordinate information at the second initial position.

[0067] The frame 10 is the installation base for the driving device 20, the labeling device 30 and the visual recognition device 40, and has a certain structural height. The structural form of the frame 10 is not limited. For example, it can be the support member 11 including the bottom and the mounting member 12 installed on the support member 11 as shown in the figure. The mounting member 12 can be a plate-shaped member, a block-shaped member or the like. The length direction of the mounting member 12 can extend along the second direction Y in the figure. In some embodiments, the second direction Y is a horizontal direction.

[0068] The driving device 20 is installed on the frame 10, specifically, it can be installed on the mounting member 12 of the frame 10. The driving device 20 is mainly used to drive the labeling device 30 and the visual recognition device 40 to move, thereby driving the labeling device 30 to pick up and attach labels.

[0069] In some embodiments, the driving device 20 can be a robot arm, or can be a driving structure described below that can perform movements with three degrees of freedom.

[0070] The visual recognition device 40 is mainly used to visually identify the position of the labeling area of ​​the battery device, and can also identify the position where the labeling device 30 picks up the label. The visual recognition device 40 transmits the acquired image information to the driving device 20, thereby instructing the action of the driving device 20, so that the driving device 20 can drive the labeling device 30 to pick up and attach the label.

[0071] The visual recognition device 40 is used to identify the labeling position, and the driving device 20 drives the labeling device 30 to move between the first initial position and the labeling position, thereby realizing automatic labeling operation. Compared with manual labeling, the labeling efficiency and accuracy can be improved.

[0072] In some embodiments, the visual recognition device 40 is communicatively connected to a control structure, the control structure is communicatively connected to the drive device 20 , and the control structure instructs the action of the drive device 20 based on the image information recognized by the visual recognition device 40 .

[0073] It should be noted that "communication connection" refers to the connection between two structures via wired communication (such as Ethernet, optical fiber, serial port connection) and wireless communication (such as Wi-Fi, Bluetooth, NFC). The communication connection enables data, voice or video transmission between devices.

[0074] The control structure may be a control device built into the visual recognition device 40 or the drive device 20, or may be an independent control device as described below. The optional structural form of the control device is given below.

[0075] The first initial position refers to the position of the labeling device 30 before picking up and attaching the label, and the second initial position refers to the position of the visual recognition device 40 before picking up and attaching the label. The first position and the second position are different positions. In some embodiments, the first position and the second position are arranged at intervals along the second direction, that is, the labeling device 30 and the visual recognition device 40 are arranged at intervals along the second direction.

[0076] In this embodiment, the visual recognition device 40 is configured to be able to detect its own coordinate information at the second initial position. After obtaining the coordinate information, it is possible to determine whether the visual recognition device 40 is in the accurate initial position manually or by the following control device, and then to know whether the visual recognition device 40 is loose or the driving device 20 is abnormal. After knowing that the position of the visual recognition device 40 is normal, the labeling operation can be performed, which can further improve the accuracy of subsequent labeling operations.

[0077] The above detection can be performed only at the first piece of a shift (when the first label attaching operation of a batch is performed), or can be performed every time the visual recognition device 40 is reset to the second initial position.

[0078] Combined with Figure 3 As shown, in some examples, optionally, the visual recognition device 40 includes an image acquisition component 41, the battery labeling equipment also includes a calibration part 42, the image acquisition component 41 is connected to the driving device 20 or the labeling device 30, and when the visual recognition device 40 is in the second initial position, the calibration part 42 faces the camera setting of the image acquisition component 41, and the image acquisition component 41 is configured to obtain its own coordinate information by obtaining image information of the calibration part 42.

[0079] The image acquisition component 41 may include a camera or a video camera. In some embodiments, the image acquisition component 41 may include a charge coupled device camera (CCD visual camera), which mainly includes an optical component, a CCD chip, and an image processing unit. The optical component is responsible for capturing light and focusing it on the CCD chip, the CCD chip converts the light signal into an electrical signal, and the image processing unit processes the electrical signal into a visible image, which has high sensitivity and imaging stability.

[0080] Of course, the image acquisition component 41 of this embodiment can also use a CMOS camera, a scanning camera, etc. to replace the CCD visual camera.

[0081] When the visual recognition device 40 is in the second initial position, the calibration member 42 is disposed facing the camera of the image acquisition component 41 . In some embodiments, the calibration member 42 may be located directly below the image acquisition component 41 .

[0082] This embodiment adopts a camera calibration method, using an image acquisition component 41 to shoot a calibration part 42 of a fixed size and position that is known, extracting the position of feature points on the calibration part 42 through image processing technology, and then calculating the internal and external parameters of the image acquisition component 41 through a calibration algorithm, thereby determining the position of the image acquisition component 41 in the world coordinate system, and achieving higher detection accuracy, thereby providing accuracy assurance for subsequent labeling.

[0083] The image acquisition component 41 may have an image processing module and a data processing module built in, or the image acquisition component 41 may be connected to the following control device, and the control device is used to perform image processing and data processing to obtain its own coordinate information.

[0084] Of course, in addition to the above-mentioned camera calibration method, the two-line method and the angle intersection method can also be used to obtain the coordinates of the visual recognition device 40.

[0085] Taking the two-line method as an example, the above-mentioned calibration part 42 may not be provided, but a linear light source or laser may be added to the visual recognition device 40 to measure the position of the target point relative to the intersection of the two lines, thereby calculating the coordinates of the target point.

[0086] Taking the angle intersection method as an example, by using a measuring device (such as a theodolite or a laser goniometer) on two or more control points of known positions, the angle of the target point (visual recognition device 40) relative to these control points is measured, thereby calculating the coordinates of the target point.

[0087] Combined with Figure 4As shown, in some examples, optionally, the calibration member 42 is provided with a calibration portion 4231 for facing the image acquisition component 41 , the calibration portion 4231 is a hole or a protrusion, and the image acquisition component 41 obtains its own coordinate information by acquiring image information of the calibration portion 4231 .

[0088] The calibration member 42 includes a base 421 , support rods 422 and a calibration plate 423 . The number of the support rods 422 may be one or more as shown in the figure. In some implementations, the lower ends of the plurality of support rods 422 are mounted on the plurality of bases 421 in a one-to-one correspondence.

[0089] The calibration plate 423 can be installed on the support member 11 by means of fasteners such as bolts, and the calibration plate 423 is provided with the above-mentioned calibration portion 4231 .

[0090] The calibration member 42 is provided with a calibration portion 4231, which is a hole or a protrusion. The hole or protrusion is usually of a regular geometric shape with clear edges, and is easy to be accurately identified and located by an image processing algorithm. This helps to improve the accuracy of camera calibration, thereby more accurately determining the internal and external parameters of the camera.

[0091] Compared with the outer contour of the calibration part 4231 which may be affected by factors such as irregular shape, blurred edges or background interference, resulting in inaccurate feature point extraction, using holes or protrusions as feature points can reduce the mismatch rate because their shape and position are relatively fixed.

[0092] In addition, the feature points of holes or protrusions have good stability under different lighting conditions and different viewing angles. This makes the camera calibration process more adaptable to environmental changes and improves the robustness of the calibration results.

[0093] In some examples, optionally, the calibration portion 4231 is a hole, and the holes include a first calibration hole 42311, a second calibration hole 42312, and a third calibration hole 42313. The image acquisition component 41 obtains its own coordinate information by respectively obtaining the diameter of the first calibration hole 42311, the diameter of the second calibration hole 42312, and the diameter of the third calibration hole 42313, and respectively obtaining the center distance between the first calibration hole 42311, the second calibration hole 42312, and the third calibration hole 42313.

[0094] The image acquisition component 41 obtains the image of the calibration part 42 and uses the following control device or internal control structure (not shown in the figure) to calculate the diameter of the first calibration hole 42311, the diameter of the second calibration hole 42312 and the diameter of the third calibration hole 42313 respectively.

[0095] It is also possible to obtain the center distance between the first calibration hole 42311 and the second calibration hole 42312 , the center distance between the first calibration hole 42311 and the third calibration hole 42313 , and the center distance between the second calibration hole 42312 and the third calibration hole 42313 .

[0096] Taking the image acquisition component 41 including a CCD vision camera as an example, after obtaining the above data, the coordinate information of the CCD vision camera can be calculated using a camera calibration algorithm.

[0097] In some embodiments, the specific data processing process is as follows:

[0098] Image acquisition, acquiring an image of the calibration part 42;

[0099] Feature extraction, through image processing, and using edge detection, corner detection and other algorithms, the center positions of the first calibration hole 42311, the second calibration hole 42312 and the third calibration hole 42313 are extracted.

[0100] The coordinates are determined. The world coordinate systems of the first calibration hole 42311, the second calibration hole 42312 and the third calibration hole 42313 are known. The world coordinates of the center of the first calibration hole 42311 are P1(X 1 ,Y 1 ,Z 1 ), the world coordinate of the center of the second calibration hole 42312 is P2(X 2 ,Y 2 ,Z 2 ), the world coordinates of the center of the third calibration hole 42313 are P3(X 3 ,Y 3 ,Z 3 ), the image acquired by the CCD visual camera can obtain the image coordinates of the first calibration hole 42311, the second calibration hole 42312 and the third calibration hole 42313. The image coordinates of the center of the first calibration hole 42311 are p1(x1, y1, z1), and the image coordinates of the center of the second calibration hole 42312 are p2(x 2 ,y 2 ,z 2 ), the image coordinates of the center of the third calibration hole 42313 are p2(x 3 ,y 3 ,z 3 ).

[0101] Camera calibration, use camera calibration to determine the camera's internal and external parameters. The internal parameters include focal length, principal point coordinates, etc., and the external parameters include rotation matrix R and translation vector T. The purpose of camera calibration is to establish the relationship between the world coordinate system and the camera coordinate system.

[0102] The conversion from the world coordinate system to the camera coordinate system is to convert the positions of the three holes of the calibration piece 42 in the world coordinate system to the camera coordinate system according to the camera calibration result. The conversion formula is:

[0103]

[0104] Where R is the rotation matrix and T is the translation vector.

[0105] Calculate the camera coordinates by the known positions Pc of the first calibration hole 42311, the second calibration hole 42312 and the third calibration hole 42313 in the camera coordinate system respectively 1 (Xc 1 ,Yc 1 ,Zc 1 ), Pc 2 (Xc 2 ,Yc 2 ,Zc 2 ) and Pc 3 (Xc 3 ,Yc 3 ,Zc 3 ), and their positions in the image coordinate system p 1 (x 1 ,y 1 ,z 1 ), p 2 (x 2 ,y 2 ,z 2 ) and p 2 (x 2 ,y 2 ,z 2 ), using the perspective projection formula:

[0106]

[0107] Where f is the focal length of the camera.

[0108] Determine the camera position. According to the above steps, the position of the CCD vision camera in the world coordinate system can be determined. The CCD vision camera coordinates can be calculated by the following formula:

[0109]

[0110] Among them, R -1 is the inverse of the rotation matrix.

[0111] The above technical solution uses simple image processing technology to extract the center position and diameter of the hole, combined with the known size of the calibration piece, to achieve fast and accurate image acquisition component calibration and coordinate acquisition. Then the detected coordinates of the first calibration hole 42311, the second calibration hole 42312, and the third calibration hole 42313 are compared with the preset world coordinates of the three.

[0112] Combined with Figure 3 and attached Figure 5 As shown, in some examples, optionally, the visual recognition device 40 further includes a light emitting component 43, and the light emitting component 43 is used to provide a light source for the image acquisition component 41 in the second initial position.

[0113] The structure of the light emitting component 43 is not limited, as long as it can emit light to provide a light source for the visual recognition device 40. In some embodiments, the visual recognition device 40 can be a lamp. The light emitting component 43 can move with the visual recognition device 40, or it can be fixed in position and only used for lighting when the visual recognition device 40 performs coordinate detection.

[0114] In this embodiment, the visual recognition device 40 is designed to include a light-emitting component 43, which can provide a light source for the visual recognition device 40, thereby significantly improving image quality and detection accuracy, while being able to adapt to a variety of detection scenarios and requirements.

[0115] In some examples, optionally, the light emitting component 43 includes a light emitting ring 431 , which is connected to the labeling device 30 and arranged relative to the image acquisition component 41 along a first direction X, where the first direction X is an arrangement direction from the driving device 20 to the frame 10 .

[0116] The light-emitting ring 431 can be connected to the labeling device 30 by mechanical connection (such as welding, bonding, bolt connection, clamping), etc. For example, the light-emitting ring 431 can be directly or indirectly connected to the second mounting frame 34 described below.

[0117] In some embodiments, the light-emitting ring 431 may be connected to a connecting arm 432 , one end of the connecting arm 432 is fixedly connected to the light-emitting ring 431 , and the other end is connected to the labeling device 30 via the above-mentioned mechanical connection method.

[0118] The radial dimension of the inner wall of the luminous circle 431 should be greater than or equal to the range of the field of view of the image acquisition component 41 extending to the luminous circle 431, so as to facilitate image acquisition by the image acquisition component 41. The field of view of the camera is indicated by a dotted line in the figure.

[0119] The light-emitting component 43 is designed to include a light-emitting ring 431. Light can pass through the middle of the light-emitting ring 431 without affecting the visual recognition device 40 in acquiring images. The light-emitting ring 431 moves with the labeling device 30 and the image acquisition component 41. Therefore, it can provide a light source during the entire process of the image acquisition component 41 acquiring images, which can facilitate the camera to acquire image information of the target object under the light-emitting ring 431. In addition, the annular light-emitting ring 431 can provide uniform lighting, ensuring that the contrast between the target object and the background in the image is maximized, thereby improving the image quality.

[0120] Combined with Figure 3 and attached Figure 6 As shown, in some examples, optionally, the labeling device 30 includes an adsorption mechanism 31, which is connected to the driving device 20 and is used to adsorb the label.

[0121] The adsorption mechanism 31 may include a suction cup, which is connected to a negative pressure pipeline (not shown in the figure). When performing labeling operations, the suction cup is driven to move by the driving device 20, and first uses its own negative pressure to absorb the label transferred from the label feeding equipment (not shown in the figure), and then uses the visual recognition device 40 to identify and move the label to the labeling area of ​​the battery device, press down the label and release the adsorption of the label to complete the labeling operation.

[0122] The shape and size of the suction cup can match the shape of the label, or can be slightly larger or smaller than the size of the label, as long as it can meet the requirements of picking up, placing and pressing down the label.

[0123] The suction cup can be used to pick up and place only one label at a time, or the suction cup can be sized to accommodate the simultaneous pick up and placement of multiple labels.

[0124] In this embodiment, the labeling device 30 is designed to include an adsorption mechanism 31. The adsorption mechanism 31 is used to pick up and place labels, which can achieve a high-precision labeling effect, improve the flatness and firmness of label pasting, and thus improve the labeling quality. In addition, the adsorption mechanism 31 can adapt to labels of different sizes and shapes, and by adjusting the position and pressure of the adsorption mechanism 31, it can flexibly respond to various labeling needs.

[0125] In some examples, optionally, the labeling device 30 also includes a rotating mechanism 32, the rotating mechanism 32 is connected to the driving device 20, the adsorption mechanism 31 is installed on the rotating mechanism 32 and connected to the driving device 20 through the rotating mechanism 32, the axial direction of the rotating mechanism 32 is set along the first direction X, the first direction X is the arrangement direction from the driving device 20 to the frame 10, and the rotating mechanism 32 is used to drive the adsorption mechanism 31 to rotate around the axial direction of the rotating mechanism 32.

[0126] In some embodiments, the first direction X may be a vertical direction, and the rotating mechanism 32 may drive the adsorption mechanism 31 to rotate around the axial direction of the rotating mechanism 32 .

[0127] The purpose of this design is that when the cross-section of the suction cup of the adsorption mechanism 31 is a rectangle or other non-circular cross-section, the angle of the suction cup can be adjusted by rotating the suction cup so that the label can be aligned, the stability of the suction cup moving the label can be improved, the label can be more accurately attached to the battery device at a preset angle, and the labeling areas of different battery shapes can be matched, further improving the accuracy of labeling.

[0128] The rotating mechanism 32 may include a hollow cylindrical structure. The cylindrical structure may be provided with a rotating driving member (not shown in the figure) inside or outside. The rotating shaft of the rotating driving member is coaxially connected to the adsorption mechanism 31 .

[0129] In order to facilitate the installation of the rotating mechanism 32 and the adsorption mechanism 31, the labeling device 30 of this embodiment also includes a first mounting frame 33 and a second mounting frame 34. The first mounting frame 33 is connected to the driving device 20 by bolts and other connecting parts. The upper end of the rotating mechanism 32 is installed on the first mounting frame 33, and the lower end of the rotating mechanism 32 is connected to the second mounting frame 34. The adsorption mechanism 31 is installed on the second mounting frame 34.

[0130] The present embodiment does not impose too many restrictions on the shapes of the first mounting frame 33 and the second mounting frame 34 , as long as they can meet the installation requirements of the rotating mechanism 32 and the adsorption mechanism 31 respectively.

[0131] Combined with the attachment again Figure 6 As shown, in some examples, optionally, the labeling device 30 further includes a pressing mechanism 35, which is connected to the driving device 20 and is used to press down the label.

[0132] The pressing mechanism 35 may be directly or indirectly connected to the driving device 20 . For example, the pressing mechanism 35 may be installed on the first mounting frame 33 or the second mounting frame 34 .

[0133] In some embodiments, the pressing mechanism 35 is installed on the rotating mechanism 32 and rotates synchronously with the adsorption mechanism 31, so that the pressing mechanism 35 can adjust its position together with the adsorption mechanism 31 under the drive of the rotating mechanism 32, making it convenient for the pressing mechanism 35 to directly press down the adsorption mechanism 31 to attach the label on the battery device.

[0134] After the adsorption mechanism 31 is driven by the driving device 20 to attach the label to the battery device, the pressing mechanism 35 of this embodiment presses down the label to further improve the flatness and firmness of the label, reduce the occurrence of undesirable phenomena such as label warping or bubbles, and thus further improve the labeling quality.

[0135] In some examples, optionally, the pressing mechanism 35 includes a telescopic member 351, a connecting frame 352 and a rolling member 353 connected in sequence along a first direction X, the first direction X is the arrangement direction of the driving device 20 to the frame 10, one end of the telescopic member 351 is connected to the rotating mechanism 32, and the other end is connected to the connecting frame 352, the rolling member 353 is rotatably installed on the connecting frame 352, and the telescopic member 351 is used to drive the connecting frame 352 and the rolling member 353 to move along the first direction X.

[0136] The telescopic member 351 refers to a structure that can be telescoped in a certain direction. In some embodiments, the telescopic member 351 can be telescoped in the first direction X, or in a direction that is an acute angle with the first direction X, as long as it can drive the connecting frame 352 and the rolling member 353 to move downward.

[0137] In some embodiments, the rolling member 353 is a roller, which is mounted on the connecting frame 352 to rotate around its own axis. The connecting frame 352 can be connected to the lower end of the telescopic member 351.

[0138] When pressing the label down, the telescopic member 351 drives the connecting frame 352 and the rolling member 353 to press down, and the driving device 20 can drive the rolling member to move along the second direction Y and the third direction Z in the figure, so as to compact all areas of the label and further improve the stability of the label after being installed on the battery device.

[0139] In some examples, optionally, one end of the telescopic member 351 is hinged to the driving device 20 , and the other end is hinged to the connecting frame 352 .

[0140] One end of the telescopic member 351 is hinged to the driving device 20. The telescopic member 351 and the driving device 20 may be directly hinged or indirectly hinged. In some embodiments, the upper end of the telescopic member 351 is hinged to the rotating mechanism 32. Specifically, the upper end of the telescopic member 351 may be hinged to the above-mentioned cylindrical structure. At this time, the rotating mechanism 32 only drives the adsorption mechanism 31 to rotate.

[0141] Alternatively, the upper end of the telescopic member 351 may be hingedly mounted on the rotating drive member of the rotating mechanism 32 or the second mounting frame 34, so that the rotating mechanism 32 can simultaneously drive the telescopic member 351 and the adsorption mechanism 31 to rotate, so that the position relationship between the rolling member 353 and the suction cup below the telescopic member 351 is fixed, making it convenient for the rolling member 353 to directly press down after the suction cup places the label.

[0142] The lower end of the telescopic member 351 is hinged to the connecting frame 352. In some embodiments, the length direction of the telescopic member 351 can be as follows: Figure 3As shown, the telescopic member 351 is arranged at an acute angle to the first direction X. When the rolling member 353 abuts against the label and the telescopic member 351 is extended and retracted, the upper and lower ends of the telescopic member 351 rotate in opposite directions at the same time, driving the rolling member 353 and the connecting member to move along the first direction X in the figure and the second direction Y in the figure, so that the downward pressure and translation of the rolling member 353 can cover most or all areas of the label.

[0143] During the pressing process of the pressing mechanism 35 , the driving device 20 can also drive the pressing mechanism 35 to move along the first direction X and the second direction Y, thereby providing a better label rolling effect.

[0144] In some embodiments, the connecting frame 352 can also be designed to have an elastic portion (not shown in the figure), which can be located at the upper end of the connecting frame 352. The elastic portion can undergo elastic deformation along the first direction X. For example, when the downward pressure of the rolling member 353 along the first direction X affects its own movement along the second direction Y, the elastic portion can be compressed, so that the rolling member 353 can not only press the label, but also roll the label along the second direction Y.

[0145] In this embodiment, both ends of the telescopic member 351 are designed as hinged structures. When the telescopic member 351 is extended and retracted, the two ends of the telescopic member 351 rotate, thereby driving the rolling member 353 to generate multiple degrees of freedom to better perform the label pressing operation.

[0146] Combined with Figure 3 and attached Figure 7 As shown, in some examples, optionally, the labeling device 30 further includes a dust cleaning mechanism 36, which is connected to the driving device 20 and is used to clean dust from the battery labeling area.

[0147] The cleaning mechanism 36 can be directly or indirectly connected to the driving device 20. For example, the cleaning mechanism 36 can be installed on the above-mentioned first mounting frame 33, or on the second mounting frame 34, or directly on the third driving mechanism 23 described below of the driving device 20.

[0148] The cleaning mechanism 36 is used to remove dust from the battery labeling area, which means that the cleaning mechanism 36 can remove at least part of the dust from the battery labeling area, thereby providing a clean installation surface for the installation of the label, so that the label can be more firmly bonded to the battery labeling area, thereby improving the stability of the label after bonding.

[0149] In some examples, optionally, the dust cleaning mechanism 36 includes an air blowing line 361, and the air blowing line 361 is used to blow air into the battery labeling area.

[0150] The dust cleaning mechanism 36 is designed to include an air blowing pipeline 361, and the air outlet of the air blowing pipeline 361 is used for dust cleaning, which has a simple structure and is easy to implement.

[0151] The air blowing pipeline 361 can be connected to and communicate with an external gas delivery device (not shown in the figure). The gas delivery device can be any structure such as an air compressor, a fan, etc. that can deliver air flow to the air blowing pipeline 361. This embodiment will not list them one by one.

[0152] In some embodiments, the lower end of the blowing pipe 361 may be slightly higher than the bottom end of the suction cup, for example, the difference between the two is between 1 mm and 100 mm, so as not to affect the suction cup adsorbing the label and can be closer to the battery labeling area.

[0153] Combined with the attachment again Figure 1 As shown, in some examples, optionally, the driving device 20 includes a first driving mechanism 21, a second driving mechanism 22 and a third driving mechanism 23. The first driving mechanism 21 is installed on the frame 10 and connected to the second driving mechanism 22.

The second driving mechanism 22 is connected to the third driving mechanism 23 and is used to drive the third driving mechanism 23 to move along the third direction Z. The third driving mechanism 23 is connected to the labeling device 30 and is used to drive the labeling device 30 to move along the first direction X. The first direction X is the arrangement direction of the driving device 20 to the frame 10.

[0154] The first driving mechanism 21 may include a first driving member 211 and a first linear reciprocating motion component 212. The first driving member 211 is transmission-connected to the first linear reciprocating motion component 212. The second driving mechanism 22 is installed on the first linear reciprocating motion component of the first linear reciprocating motion component 212. The first driving member 211 drives the first linear reciprocating motion component of the first linear reciprocating motion component 212 to move, thereby driving the second driving mechanism 22 to move along the second direction Y in the figure.

[0155] Similarly, the second driving mechanism 22 may include a second driving member 221 and a second linear reciprocating motion component 222. The second driving member 221 is installed on the above-mentioned first linear reciprocating motion component. The second driving member 221 is transmission-connected to the second linear reciprocating motion component 222. The third driving mechanism 23 is installed on the second linear reciprocating motion component of the second linear reciprocating motion component 222. The second driving member 221 drives the second linear reciprocating motion component of the second linear reciprocating motion component 222 to move, thereby driving the third driving mechanism 23 to move along the third direction Z in the figure.

[0156] Further, the third driving mechanism 23 may include a third driving member 231 and a third linear reciprocating motion component 232. The third driving member 231 is installed on the above-mentioned second linear reciprocating motion component. The third driving member 231 is transmission-connected to the third linear reciprocating motion component 232. The first mounting frame 33 of the labeling device 30 is installed on the third linear reciprocating motion component of the third linear reciprocating motion component 232. The third driving member 231 drives the third linear reciprocating motion component of the third linear reciprocating motion component 232 to move, thereby driving the labeling device 30 to move along the first direction X in the figure.

[0157] In some embodiments, the first driving member 211 may include a motor, specifically a servo motor, the first linear reciprocating motion component 212 may include a screw slider, and the first linear reciprocating motion component may be a slider in the screw slider. Similarly, the second driving member 221 and the third driving member may also include a motor, and the second linear reciprocating motion component 222 and the third reciprocating motion component may also include a screw slider, respectively.

[0158] In addition, the lead screw slider may be replaced by a crank slider, a gear rack, or other components that can convert rotary motion into linear motion, which are not listed one by one in this embodiment.

[0159] Of course, the structural forms of the first drive mechanism 21, the second drive mechanism 22 and the third drive mechanism 23 of the present embodiment are not limited thereto. For example, the three can also be structures capable of linear motion, such as cylinders, hydraulic cylinders, electric cylinders, etc. The cylinder body of the cylinder is the above-mentioned first drive member 211, the second drive member 221 and the third drive member, and the piston rod of the cylinder is the above-mentioned first linear reciprocating motion component, the second linear reciprocating motion component and the third linear reciprocating motion component.

[0160] In this embodiment, the driving device 20 is designed to include a first driving mechanism 21, a second driving mechanism 22 and a third driving mechanism 23. The first driving mechanism 21 drives the second driving mechanism 22 to move along the second direction Y, the second driving mechanism 22 drives the third driving mechanism 23 to move along the third direction Z, and the third driving mechanism 23 drives the labeling device 30 to move along the first direction X, so that the driving device 20 drives the labeling device 30 to move along the first direction X, the second direction Y and the third direction Z with three degrees of freedom, thereby improving the flexibility of the labeling device 30 and making labeling operations more convenient.

[0161] In some embodiments of the present application, the battery labeling device 100 also includes a control device (not shown in the figure), which is communicatively connected to the visual recognition device 40. The control device is configured to receive coordinate information detected by the visual recognition device 40 and compare the coordinate information with preset coordinates to determine whether the visual recognition device 40 is misaligned.

[0162] The control device is used to compare the coordinate information detected by the visual recognition device 40 with the preset coordinates to automatically and intelligently determine whether the visual recognition device 40 is misaligned. The result is more accurate and convenient for subsequent early warning.

[0163] The control device may be an independent control structure or a control structure built into the visual recognition device 40. In some embodiments, the control device may include a control circuit such as a PLC or an MCU that can receive data, process data, and send control signals.

[0164] The control device is respectively connected to the visual recognition device 40, the first drive device 20, the second drive device 20 and the third drive device 20 for communication, and sends control instructions to the drive device 20 by acquiring the image of the visual recognition device 40, so that the drive device 20 can drive the labeling device 30 to move to the designated area for picking up and attaching labels.

[0165] The control device stores preset coordinates inside, or the visual recognition device 40 stores preset coordinates inside. The preset coordinates are ideal coordinates of the image acquisition component 41 of the visual recognition device 40. When the difference between the two is within a preset range, for example, in the X, Y, and Z coordinate systems (in some embodiments, the first direction X, the second direction Y, and the third direction Z in the figure), when the difference between the preset coordinates and the difference detected by the visual recognition device 40 is not greater than 2 mm in any direction, it is determined that the visual recognition device 40 is in a normal position, the driving device 20 or the recognition device is not loose, and labeling operations can be performed.

[0166] Correspondingly, when the above-mentioned difference is greater than 2 mm, it indicates that the visual recognition device 40 or the driving device 20 is loose. At this time, the control device may be connected to a display device or an alarm device (not shown in the figure) to prompt the staff to make corrections through the display device or the alarm device.
