[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] like Figures 1 to 4 As shown, the crane 100 for automatically reading cargo label information in this embodiment of the present invention includes a body 1, a robotic arm 2, a barcode scanning module 31, a hoisting assembly 4, and a sensor module.

[0033] The machine body 1 includes a crossbeam 11. The robotic arm 2 is mounted on the crossbeam 11. The robotic arm 2 includes a multi-segment forearm and a scanning unit 3. The forearm can drive the scanning unit 3 to move.

[0034] A barcode scanning module 31 is located in the barcode scanning unit 3. The barcode scanning module 31 is used to obtain the information stored in the label on the goods 200. The lifting assembly 4 is used to lift the goods 200.

[0035] The sensor module is used to detect the position and status of the hoisting assembly 4.

[0036] For example, the body 1 provides an overall support structure and provides a mounting position for the robotic arm 2 through the crossbeam 11 on it; the robotic arm 2 is mounted on the crossbeam 11 and consists of multiple movable forearms and a scanning unit 3 for mounting the scanning module 31. These forearms can move flexibly to drive the scanning unit 3 to accurately position the label of the goods 200.

[0037] The barcode scanning module 31 is located in the barcode scanning unit 3 and is specifically responsible for reading the information stored in the label of the goods 200.

[0038] The lifting component 4 is used to actually lift the cargo 200, so that the entire device can not only automatically identify the cargo 200 information, but also realize the cargo 200 handling function.

[0039] The sensor module is used to detect the specific position and status of the hoisting component 4, ensuring that the scanning operation is initiated at the appropriate time. At the same time, it monitors key parameters throughout the process, ensuring that the hoisting and information collection of cargo 200 can be completed safely and accurately without human intervention, thereby improving work efficiency and automation level.

[0040] In this embodiment of the invention, when the crane 100, which automatically reads cargo label information, needs to handle cargo 200, the lifting assembly 4 is first used to lift the cargo 200. It moves along the crossbeam 11 to a designated position and adjusts its posture according to the size and shape of the cargo 200 to ensure a firm grip or hold. Once the cargo 200 is successfully lifted, the sensor module begins to monitor the position and status of the lifting assembly 4 in real time, ensuring the safety and accuracy of the entire process.

[0041] After the hoisting assembly 4 lifts the cargo 200 to the preset position, the sensor module confirms that the robotic arm 2 and the barcode scanner 3 are in place. At this time, the robotic arm 2 is activated, causing it to move the barcode scanner 3 close to the label on the cargo 200 along the preset path, and quickly acquire and record the information in the label.

[0042] In related technologies, when a crane lifts a 200-ton load, the operator needs to perform manual scanning for a long time, which is labor-intensive and can easily cause fatigue, affecting work efficiency and accuracy.

[0043] The crane 100, which automatically reads cargo label information according to this embodiment of the invention, greatly reduces the burden on operators by integrating an automated robotic arm 2 and a high-precision barcode scanning module 31. The robotic arm 2 can automatically adjust its posture according to the position of the cargo 200 and accurately position itself at the label, completing the label scanning without manual intervention. This not only improves the scanning speed and accuracy but also significantly reduces the labor intensity of manual operation. At the same time, the sensor module monitors the status and position of the lifting assembly 4 in real time, ensuring that the barcode scanning operation is initiated at the appropriate time. This further enhances the automation level and work efficiency of the crane 100, making the cargo lifting and information collection process smoother, more efficient, and safer, avoiding errors and inefficiencies caused by human fatigue.

[0044] Therefore, the crane 100 that automatically reads cargo label information according to this utility model embodiment not only improves operating efficiency, but also improves the reliability and safety of the work.

[0045] In some embodiments, such as Figure 2 As shown, the robotic arm 2 includes a base 20, a first forearm 21, a second forearm 22, and a third forearm 23. The base 20 is fixed to one end of the crossbeam 11. One end of the first forearm 21 is rotatably connected to the base 20. The first forearm 21, the second forearm 22, and the third forearm 23 are connected in sequence, and the third forearm 23 is connected to the scanning unit 3.

[0046] For example, the base 20 is fixed to the end face of one end of the crossbeam 11, and one end of the first forearm 21 is connected to the base 20 by a rotatable connection, so that the first forearm 21 can rotate flexibly and adjust its angle within a certain range.

[0047] The first forearm 21, the second forearm 22, and the third forearm 23 are connected in sequence to form a progressive telescopic and bending structure. This design not only expands the operating range of the robotic arm 2, but also enhances its flexibility and positioning accuracy. The third forearm 23, as the end part of the robotic arm 2, is directly connected to the barcode scanner 3, which can accurately move the barcode scanner 3 to the target position, thereby realizing efficient scanning and information collection of the label on the goods 200.

[0048] The crane 100 of this utility model, which automatically reads cargo label information, can flexibly deploy the number of forearms according to the position of the label on the cargo 200 during operation. For example, when the label on the cargo 200 is close and within the basic coverage area of ​​the robotic arm 2, only the first forearm 21 needs to be activated to complete the scanning operation, thereby saving energy and improving response speed. When the label is far away or requires higher precision positioning, the crane 100 will deploy the second forearm 22 and the third forearm 23. Through the coordinated movement of multiple forearm sections, the working range of the robotic arm 2 is expanded, and the scanning unit 3 can accurately align with the label position. This intelligent deployment mechanism not only improves the adaptability of the robotic arm 2 but also optimizes the overall operating efficiency, enabling the crane 100 to flexibly cope with the label scanning needs of the cargo 200 in different scenarios. Whether it is a short or long distance, a simple or complex environment, it can efficiently complete the task.

[0049] In some embodiments, the axial dimensions of the first forearm 21, the second forearm 22, and the third forearm 23 decrease sequentially. This sequential decrease in axial dimensions of the first forearm 21, the second forearm 22, and the third forearm 23 results in a progressively compact layout for the robotic arm 2, which not only improves overall flexibility and operational precision but also effectively reduces inertia and vibration that may occur during the robotic arm 2's movement. By combining the longer first forearm 21 with the smaller third forearm 23, the robotic arm 2 can gradually reduce the size of its end-effector while ensuring sufficient torque and stability, thereby better adapting to complex operating environments and accurately positioning the label on the goods 200. This progressively smaller size design also optimizes the weight distribution of the robotic arm 2, making it more stable and efficient during extension, retraction, and rotation.

[0050] In some embodiments, the crane 100 that automatically reads cargo label information includes a controller, and the barcode scanning module 31 is electrically connected to the controller.

[0051] For example, the barcode scanning module 31 interacts with the controller via electrical connection to exchange data and transmit commands. This design allows the barcode scanning module 31 to transmit the collected label information to the controller in real time. Simultaneously, the controller can send operation commands to the barcode scanning module 31 based on preset programs or sensor feedback, thereby achieving precise control of the scanning process. Through this close linkage mechanism, the crane 100, which automatically reads cargo label information, can automatically complete information collection, processing, and recording without human intervention, not only improving operational efficiency but also enhancing the intelligence level of the crane 100.

[0052] In some embodiments, such as Figure 1As shown, the hoisting assembly 4 includes a hoisting chain 41 and a suction cup 42. One end of the hoisting chain 41 is connected to the crossbeam 11, and the other end of the hoisting chain 41 is connected to the suction cup 42.

[0053] For example, one end of the lifting chain 41 is securely connected to the crossbeam 11, ensuring the reliable suspension and load-bearing capacity of the entire lifting assembly 4; the other end of the lifting chain 41 is connected to the suction cup 42, a design that allows the suction cup 42 to move flexibly and accurately pick up the goods 200 as needed. By adjusting the length and angle of the lifting chain 41, the lifting assembly 4 can adapt to lifting tasks of goods 200 at different heights and positions, not only improving operational flexibility but also ensuring stability and safety during the lifting process.

[0054] In some embodiments, the sensor module includes a position sensor and a status sensor, wherein the position sensor is used to detect the position of the hoisting assembly 4 and the status sensor is used to detect the load status of the hoisting assembly 4.

[0055] For example, the position sensor accurately detects the position of the lifting component 4, providing real-time feedback on its specific coordinates and posture in space, ensuring that the robotic arm 2 can operate precisely according to the actual position of the lifting component 4. Simultaneously, the status sensor focuses on monitoring the load status of the lifting component 4, including but not limited to the suction force of the suction cup 42, the weight of the cargo 200, and its balance, ensuring that each lifting operation is safe and reliable. Through this dual monitoring mechanism, the sensor module not only provides crucial data support, enabling the controller to make more accurate operational decisions, but also effectively prevents potential safety hazards, such as overload or cargo 200 slippage. Therefore, the crane 100 of this embodiment, which automatically reads cargo label information, can automatically adjust and optimize the lifting and scanning process without human intervention, ensuring efficient and stable operation and significantly improving overall work efficiency and safety.

[0056] In some embodiments, the status sensor is a pressure sensor, which is disposed on the surface of the suction cup 42 to detect the pressure of the suction cup 42.

[0057] For example, a pressure sensor is installed on the surface of the suction cup 42, specifically for detecting the pressure distribution when the suction cup 42 comes into contact with the cargo 200. By monitoring the pressure changes on the surface of the suction cup 42 in real time, the pressure sensor can accurately determine whether the suction cup 42 is firmly attached to the cargo 200, and whether the suction force is uniform and strong enough, ensuring stability and safety during the lifting process.

[0058] The crane 100 of this utility model, which automatically reads cargo label information, not only improves operational reliability but also allows the crane 100 to dynamically adjust the operating parameters of the suction cup 42 based on the actual adsorption effect. For example, it can automatically increase the vacuum or adjust the position of the suction cup 42 when insufficient adsorption force is detected to ensure optimal adsorption. Furthermore, data provided by the pressure sensor can help prevent potential operational risks, such as avoiding cargo 200 slippage due to weak adsorption, thereby further enhancing the automation level and operational safety of the crane 100.

[0059] In some embodiments, such as Figure 3 As shown, there are multiple lifting assemblies 4, which are arranged sequentially along the crossbeam 11. For example, the arrangement of multiple lifting assemblies 4 not only expands the coverage of the crane 100 that automatically reads cargo label information, but also enables it to adapt to the lifting needs of cargo 200 of different sizes, weights and positions, and can easily cope with both single-point operation and multi-point collaborative operation.

[0060] In some embodiments, such as Figure 4 As shown, the scanning unit 3 is equipped with an image acquisition module, which is electrically connected to the controller. The image acquisition module is used to acquire the location information of the tag.

[0061] The scanning unit 3 is equipped with an image acquisition module, which interacts with the controller via an electrical connection and is specifically used to acquire the position information of the labels on the goods 200. For example, during operation, when the robotic arm 2 moves the scanning unit 3 near the goods 200, the image acquisition module captures the image of the label in real time and analyzes its specific position and angle using a built-in algorithm, then transmits this information to the controller. The controller quickly adjusts the posture of the robotic arm 2 and the direction of the scanning unit 3 based on the received data, ensuring that the scanning module 31 can accurately align with the label and complete the scanning operation. This design not only improves the success rate and efficiency of label recognition but also enables the crane 100, which automatically reads the label information of the goods, to adapt to labels of goods 200 with different shapes, sizes, and placement angles, maintaining high-precision positioning capabilities even in complex environments.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
