Abstract

This application relates to a label feeding mechanism and an automated code reading / writing device. The label feeding mechanism includes a material preparation mechanism, an adsorption mechanism, and a rocker arm mechanism. The rocker arm mechanism is connected to a negative pressure adsorption component and is used to drive the movement of the negative pressure adsorption component. The rocker arm mechanism includes a mounting frame, a first driving component, a rocker arm, a lifting component, and a connecting component. The connecting component is slidably disposed on the mounting frame along a first direction. The lifting component is slidably disposed on the connecting component along a second direction. During the process of transferring the label from the material preparation position to the feeding position, the first driving component drives the rocker arm to rotate, and the rotation of the rocker arm correspondingly drives the lifting component to move. Furthermore, since the connecting component is slidably disposed on the mounting frame along the first direction, and the lifting component is slidably disposed on the connecting component along the second direction, the lifting component can drive the label adsorbed by the negative pressure adsorption component to rise and fall along the second direction, and simultaneously move along the first direction to the feeding position, which can stably grasp the label, effectively reduce jamming and deformation defects, and improve work efficiency.

[0016] In one embodiment, the placement slot is adapted to the shape of the label; and / or, the lifting mechanism is located at the bottom of the first hopper.

[0017] On the other hand, this application also provides an automated code reading and writing device, including the aforementioned label feeding mechanism, and further comprising:

[0018] A conveying mechanism is provided with a loading position and a unloading position. The conveying mechanism is used to receive the labels provided by the label loading mechanism and convey the labels from the loading position to the unloading position.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] It should be noted that the tags in this embodiment include, but are not limited to, paper tags, RFID electronic tags, NFC tags, etc. Specifically, the tags in this embodiment refer to tags made of soft and breathable materials. In one specific embodiment, the tag is set as an NFC tag, and the description will be based on an NFC tag. Of course, other types of tags can be selected in this embodiment, and no particular limitation is made here.

[0034] In related technologies, NFC tags have the following drawbacks in automated production: First, due to their soft and easily wrinkled nature, traditional feeding methods using friction wheels or mechanical grippers are prone to causing material jamming, deformation, or failure to pick up materials. Second, NFC tag production lines often employ a decentralized process model, distributing feeding, reading, writing, and unloading processes across different equipment, resulting in multiple material handling and repositioning operations. This decentralized production layout not only leads to long production cycles and low efficiency but also accumulates errors due to multiple positioning operations, severely impacting the final reading and writing accuracy and the first-pass yield. Furthermore, it requires a significant investment of manpower for material transfer and monitoring.

[0035] Based on the above reasons, this application provides a label feeding mechanism and an automated code reading and writing device, which can improve the stability and accuracy of material handling, effectively reduce jamming and deformation defects, and thus improve work efficiency.

[0036] The following will combine Figures 1 to 3 A detailed description will be provided of a label feeding mechanism and an automated code reading and writing device according to an embodiment of this application.

[0037] See Figures 1 to 3 This application provides a label feeding mechanism 10, which includes a material preparation mechanism 11, an adsorption mechanism 12, and a rocker arm mechanism 13.

[0038] The material preparation mechanism 11 is used to move the labels to the material preparation position. The material preparation position can be a fixed position or a non-fixed position, and can be flexibly adjusted according to actual needs; no restrictions are imposed here. The material preparation position can be set in conjunction with the rocker arm mechanism 13 so that the rocker arm mechanism 13 can drive the suction mechanism 12 to pick up the labels. Specifically, the material preparation mechanism 11 can move the labels to the material preparation position in various ways, such as lifting, lateral movement, etc.; no restrictions are imposed here. In order to make reasonable use of space and reduce the floor area, in one embodiment, the material preparation mechanism 11 specifically moves the labels to the material preparation position by lifting.

[0039] Please see Figure 2 For example, the material preparation mechanism 11 includes a first hopper 111, a lifting mechanism 112, and a first sensor 113. The first hopper 111 has a placement slot 1111 for stacking and storing labels to be processed (not shown in the figure). The lifting mechanism 112 includes, but is not limited to, electric push rods, cylinders, or hydraulic cylinders, etc., and is not limited here. The lifting mechanism 112 is connected to the first hopper 111 and is used to lift the labels in the first hopper 111 so that the topmost label moves to the material preparation position. The first sensor 113 is installed in the first hopper 111 and is used to sense whether there is a label at the material preparation position. Specifically, both the first sensor 113 and the lifting mechanism 112 are electrically connected to a controller. When the first sensor 113 senses that there is a label at the material preparation position, the controller controls the lifting mechanism 112 to stop operating; conversely, when the first sensor 113 senses that there is no label at the material preparation position, the controller controls the lifting mechanism 112 to lift, so that the label moves to the material preparation position.

[0040] Based on the aforementioned embodiments, the material preparation mechanism 11 further includes a second sensor 114. The second sensor 114 is disposed in the first hopper 111 or the lifting mechanism 112, and is used to sense whether there is a label in the first hopper 111. The second sensor 114 is electrically connected to the controller. When the second sensor 114 senses that there is no label in the first hopper 111, the controller controls the lifting mechanism 112 to stop working.

[0041] Please see Figure 2 and Figure 3 For example, the adsorption mechanism 12 includes a negative pressure adsorption element 121 for adsorbing labels. The negative pressure adsorption element 121 includes, but is not limited to, a vacuum suction cup 1212. Specifically, the negative pressure adsorption element 121 includes a first negative pressure tube 1211 and a vacuum suction cup 1212. One end of the first negative pressure tube 1211 is connected to the vacuum suction cup 1212. The adsorption mechanism 12 also includes a negative pressure device 122 and a connecting tube 123. The negative pressure device 122 is connected to the negative pressure adsorption element 121 via the connecting tube 123. The connecting tube 123 is specifically connected to the first negative pressure tube 1211. The negative pressure device 122 can flexibly adjust and control the negative pressure of the vacuum suction cup 1212 according to actual needs, thereby achieving stable label adsorption and being suitable for adsorbing labels of various sizes and weights.

[0042] In one embodiment, the negative pressure device 122 has multiple adjustable levels of negative pressure, for example, 3 to 5 levels. The negative pressure device 122 is electrically connected to a controller, which adjusts the number of levels of the negative pressure device 122 according to the label's air permeability, ensuring that the negative pressure of the negative pressure device 122 is positively correlated with the label's air permeability. This prevents excessive negative pressure from causing label deformation and avoids insufficient negative pressure from failing to stably adsorb the label.

[0043] For example, the rocker arm mechanism 13 is connected to the negative pressure adsorption member 121 and is used to drive the negative pressure adsorption member 121 to move, so that the negative pressure adsorption member 121 switches between the material preparation position and the material feeding position.

[0044] Specifically, the rocker arm mechanism 13 includes a mounting bracket 131, a first drive member 132, a rocker arm 133, a lifting member 134, and a connecting member 135. The first drive member 132 is mounted on the mounting bracket 131. The first drive member 132 is connected to one end of the rocker arm 133 to drive the rocker arm 133 to rotate. The other end of the rocker arm 133 is connected to the lifting member 134.

[0045] For example, the connector 135 is slidably disposed on the mounting frame 131 along a first direction, which is the arrangement direction of the material preparation position and the material loading position. The lifting member 134 is slidably disposed on the connector 135 along a second direction. The second direction is at an angle to the first direction. Optionally, the first direction is horizontal, the second direction is vertical, and the angle between the first and second directions is 90°. Of course, the angle between the first and second directions can also be any angle between 60° and 120°, or other sizes, without particular limitation.

[0046] For example, the negative pressure adsorption component 121 is installed on the lifting component 134. The lifting component 134 serves to support and lift the negative pressure adsorption component 121, and can drive the negative pressure adsorption component 121 to move synchronously, thereby transferring the label from the preparation position to the loading position.

[0047] When the label feeding mechanism 10 is in use, the preparation mechanism 11 can move the label to the preparation position; the rocker arm mechanism 13 drives the negative pressure adsorption component 121 to move to the preparation position, and the negative pressure adsorption component 121 picks up the label; after the label is picked up, the rocker arm mechanism 13 drives the negative pressure adsorption component 121 to move to the feeding position, the negative pressure adsorption component 121 breaks the vacuum and places the label at the feeding position, thus completing the label feeding and proceeding to the feeding of the next label.

[0048] In the label feeding mechanism 10 described above, during the process of transferring labels from the preparation position to the feeding position, the first driving component 132 drives the rocker arm 133 to rotate, and the rotation of the rocker arm 133 correspondingly drives the lifting component 134 to move. Furthermore, since the connecting component 135 is slidably disposed on the mounting frame 131 along the first direction, and the lifting component 134 is slidably disposed on the connecting component 135 along the second direction, the lifting component 134 can drive the labels adsorbed by the negative pressure adsorption component 121 to rise and fall along the second direction, and simultaneously move along the first direction to the feeding position. This allows for stable label gripping, effectively reducing jamming and deformation defects, and effectively reducing positional shifts caused by centrifugal motion, making the label transfer position more accurate and reliable, and improving work efficiency.

[0049] Especially for soft and breathable labels, the negative pressure adsorption component 121 stably adsorbs the label, and the rocker arm mechanism 13 moves the label along the first and second directions, so that the label can be smoothly transferred from the preparation position to the feeding position. The feeding is stable and reliable, which solves various problems such as difficulty in feeding such labels, easy material jamming, damage caused by deformation, displacement of the feeding position or failure to pick up the material, resulting in low work efficiency.

[0050] In related technologies, when the negative pressure adsorption component 121 adsorbs tags, it is prone to material stacking defects for tags made of breathable materials, which can lead to subsequent code reading / writing failures. Based on this, please refer to... Figure 3 Based on the aforementioned embodiments, the label feeding mechanism 10 further includes a vibration mechanism 14. The vibration mechanism 14 is connected to the negative pressure adsorption member 121. Specifically, the vibration mechanism 14 is sleeved onto the first negative pressure tube 1211 of the negative pressure adsorption member 121, or it can be connected to the first negative pressure tube 1211 in other ways, without particular limitation. The vibration mechanism 14 is used to drive the negative pressure adsorption member 121 to vibrate. When the negative pressure adsorption member 121 contacts and adsorbs a label, the vibration mechanism 14 is activated simultaneously, causing the negative pressure adsorption member 121 to vibrate, thereby effectively preventing label stacking defects. Because once labels are stacked, the negative pressure adsorption member 121, driven by the vibration mechanism 14, can stably adsorb only one label, while the remaining labels fall off under the action of vibration force. The vibration direction of the vibration mechanism 14 includes, but is not limited to, the horizontal or vertical direction. The specific vibration frequency, amplitude, and vibration time can be adjusted and set according to actual needs, as long as the excess labels fall off, without particular limitation.

[0051] Based on the aforementioned embodiments, the label feeding mechanism 10 further includes a bracket 15 disposed between the negative pressure adsorption member 121 and the lifting member 134. The bracket 15 is mounted on the lifting member 134, and the negative pressure adsorption member 121 is mounted on the bracket 15. Specifically, the first negative pressure tube 1211 is mounted on the bracket 15. The bracket 15 may include, but is not limited to, an L-shaped plate. Under the action of the bracket 15, there is a gap between the first negative pressure tube 1211 and the lifting member 134, providing a larger installation space for the vibration mechanism 14 and preventing interference between the vibration mechanism 14, which is mounted on the first negative pressure tube 1211, and the lifting member 134.

[0052] Please see Figure 2 In some embodiments, the mounting bracket 131 is provided with a guide member 1311 extending along a first direction. The guide member 1311 includes, but is not limited to, a guide rail. The lifting member 134 includes the guide rail. The connecting member 135 includes a first slider 1351 and a second slider 1352. The first slider 1351 and the second slider 1352 are connected. The first slider 1351 is slidably disposed on the guide member 1311, and the second slider 1352 is slidably disposed on the guide rail. Under the drive of the rocker arm 133, the lifting member 134 slides along the second slider 1352 on one hand, and drives the first slider 1351 to slide along the guide member 1311 on the other hand, thereby realizing the stable movement of the negative pressure adsorption member 121 and the label along the first and second directions.

[0053] Based on the aforementioned embodiments, in order to improve the rotational stability of the rocker arm 133, the mounting frame 131 is provided with a slide rail 13121. The other end of the rocker arm 133 is slidably disposed in the slide rail 13121. The other end of the rocker arm 133 is also rotatably connected to the lifting member 134. Specifically, the mounting frame 131 includes a mounting plate 1312, and the slide rail 13121 is formed on the mounting plate 1312. The first driving member 132 includes, but is not limited to, a motor, and the motor shaft 1321 is connected to one end of the rocker arm 133. When the first driving member 132 drives one end of the rocker arm 133 to rotate, the other end of the rocker arm 133 slides along the slide rail 13121, and the rocker arm 133 synchronously drives the lifting member 134 to move.

[0054] The mounting plate 1312 is placed vertically, and the rocker arm 133 rotates around the center of the pivot 1321 along the surface of the mounting plate 1312 when it swings. The rocker arm 133 swings between a first extreme position and a second extreme position. The initial position of the rocker arm 133, which is also the first extreme position, corresponds to the material preparation position. When it moves to the first extreme position, it can adsorb the label through the negative pressure adsorption component 121 on the lifting component 134. The final position of the rocker arm 133, which is also the second extreme position, corresponds to the material release position. When it moves to the second extreme position, it can release the label by breaking the vacuum through the negative pressure adsorption component 121. The angle between the first extreme position and the horizontal direction is, for example, 20° to 60°, and the angle between the second extreme position and the horizontal direction is, for example, 120° to 160°.

[0055] Please see Figure 2 In some embodiments, the placement groove 1111 is adapted to the shape of the label. Specifically, when the label is rectangular, the cross-sectional profile of the placement groove 1111 is rectangular. In this way, the placement groove 1111 can play the role of positioning the label and ensure the positioning accuracy of the label. Optionally, the first hopper 111 includes four angle steels 1112, which enclose to form the placement groove 1111.

[0056] For example, the lifting mechanism 112 is located at the bottom of the first hopper 111. The lifting mechanism 112 lifts the labels in the first hopper 111 upwards, so that the stacked labels are lifted one by one to the preparation position. Specifically, according to the sensing signal of the first sensor 113, the topmost label is controlled to move to the preparation position under the action of the lifting mechanism 112. The lifting mechanism 112 stops moving, and the rocker arm mechanism 13 can perform the picking action accordingly. After the rocker arm mechanism 13 drives the negative pressure suction member 121 to remove the topmost label, the lifting mechanism 112 continues to lift the stacked labels and begins the loading action of the next label.

[0057] Please see Figure 1 and Figure 2Another embodiment of this application also provides an automated code reading and writing device, including the label feeding mechanism 10 of any of the above embodiments.

[0058] For example, the automated barcode reader / writer device also includes: a conveying mechanism 20, a barcode reader 30, a barcode writer 40, and a controller.

[0059] The conveying mechanism 20 has a loading position and a unloading position. The conveying mechanism 20 is used to receive the labels provided by the label loading mechanism 10 and transport the labels from the loading position to the unloading position.

[0060] The barcode reader 30 is located between the loading and unloading positions and is used to read the labels located on the conveying mechanism 20.

[0061] The code writer 40 is located between the code reader 30 and the unloading position. The code writer 40 is used to write codes on the labels located on the conveying mechanism 20.

[0062] The controller is electrically connected to the conveying mechanism 20, the barcode reader 30, the barcode writer 40, and the label feeding mechanism 10, respectively.

[0063] The aforementioned automated label reading and writing device, on the one hand, includes a label feeding mechanism 10, and the technical effects are brought about by the label feeding mechanism 10, including the beneficial effects of the label feeding mechanism 10, which will not be elaborated here; on the other hand, the label feeding mechanism 10, the conveying mechanism 20, the label reader 30, and the label writer 40 are all electrically connected to the controller and work in coordination under the control of the controller, which can realize continuous operation of label feeding, reading, writing, and unloading. Moreover, the feeding, reading, writing, and unloading functions are seamlessly integrated and uniformly controlled by the controller, eliminating the time waste and positioning accumulation error caused by the transfer of materials between different devices, significantly improving the production rhythm, reading and writing accuracy, and product consistency, reducing labor costs, and having a high degree of automation.

[0064] Based on the aforementioned embodiments, the automated barcode reading and writing device further includes a second hopper 50. The second hopper 50 is located at the unloading position. After the label reading and writing are completed, the conveying mechanism 20 transports the labels to the second hopper 50 for collection and processing.

[0065] The conveying mechanism 20 is positioned at the end closest to the label feeding mechanism 10, and this feeding position is adjacent to the label feeding mechanism 10. The label feeding mechanism 10 can directly convey labels to the feeding position, reducing material conveying time. The other end of the conveying mechanism 20 is positioned at the unloading position, and this other end is adjacent to the second hopper 50.

[0066] Based on the aforementioned embodiments, the automated barcode reader / writer device further includes a first position sensor 61 and a second position sensor 62. Both the first position sensor 61 and the second position sensor 62 are electrically connected to the controller. The first position sensor 61 is positioned close to the barcode reader 30 and is used to sense whether a tag has moved to the barcode reader station. When the first position sensor 61 senses a tag at the barcode reader station, the controller accordingly stops the conveyor mechanism 20 and controls the barcode reader 30 to read the tag located at the barcode reader station. After the barcode reader 30 finishes reading the tag, the controller controls the conveyor mechanism 20 to continue running, causing the tag to be conveyed towards the writer 40. The second position sensor 62 is used to sense whether a tag has moved to the writing station. When the first position sensor 61 senses a tag at the writing station, the controller accordingly stops the conveyor mechanism 20 and controls the writer 40 to write the tag located at the writing station. After the writer 40 finishes writing the tag, the controller controls the conveyor mechanism 20 to continue running. Therefore, by combining the position sensing signals from the first position sensor 61 and the second position sensor 62, the delivery position of the tag can be precisely controlled, thereby ensuring that reading and writing can be carried out smoothly.

[0067] In some embodiments, two conveying mechanisms 20 are provided. The two conveying mechanisms 20 are arranged sequentially along the conveying direction. A barcode reader 30 is correspondingly arranged with respect to the upstream conveying mechanism 20, and a barcode writer 40 is correspondingly arranged with respect to the downstream conveying mechanism 20. The two conveying mechanisms 20 operate independently under the control of the controller. Specifically, when the barcode reader 30 needs to read a code, the controller stops the conveying mechanism 20 corresponding to the barcode reader 30, while the conveying mechanism 20 corresponding to the barcode writer 40 can continue operating; similarly, when the barcode writer 40 needs to write a code, the controller stops the conveying mechanism 20 corresponding to the barcode writer 40, while the conveying mechanism 20 corresponding to the barcode reader 30 can continue operating, allowing the tags to be conveyed forward. This improves work efficiency.

[0068] Based on the aforementioned embodiments, the conveying mechanism 20 includes a second driving member 21, a conveyor belt 22, a housing 23, and rotating wheels 24. The second driving member 21 includes, but is not limited to, a motor. The second driving member 21 is connected to the rotating wheels 24 and drives the rotating wheels 24 to rotate. The specific number of rotating wheels 24 is not limited and can be set to one, two, three, or other numbers according to actual needs. The rotating wheels 24 are rotatably mounted on the housing 23 and drive the conveyor belt 22 to rotate. The conveyor belt 22 is arranged around the housing 23. When the conveyor belt 22 is driven by the rotating wheels 24, it can support and convey labels.

[0069] Based on the aforementioned embodiments, the conveying mechanism 20 further includes a second negative pressure pipe 25. The conveyor belt 22 has multiple first negative pressure holes. The top wall of the housing 23 has multiple second negative pressure holes. One end of the second negative pressure pipe 25 is connected to the housing 23, and the other end is connected to the negative pressure device 122. Under the action of the negative pressure device 122, the surface of the conveyor belt 22 has an adsorption function, allowing the labels to be stably placed on the conveyor belt 22, thereby preventing the labels on the conveyor belt 22 from shifting, ensuring that the labels are accurately conveyed to the reading station and writing station, and reducing the defect rate.

[0070] In related technologies, labels may fail to be read or written, requiring them to be scrapped as defective products. Defective labels, if not separated promptly, typically need to be separated in subsequent processes, reducing work efficiency and increasing labor costs. Therefore, the automated label reader / writer device also includes a rejection mechanism 70. The rejection mechanism 70 may include, but is not limited to, a cylinder, hydraulic cylinder, or electric cylinder. The rejection mechanism 70 is electrically connected to the controller and is positioned between the label writer 40 and the unloading position. When the controller determines a label is defective, the rejection mechanism 70, under the controller's control, rejects the defective label from the conveyor mechanism 20. This effectively prevents defective labels from flowing into the second hopper 50, increasing the risk of re-inspection and improving work efficiency.

[0071] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0072] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0074] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0075] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
