Description

Technical Field

[0001] This utility model relates to the field of automated logistics, and in particular to an integrated automatic weighing and barcode scanning device for small parcels using a robotic arm. Background Technology

[0002] With the booming development of e-commerce, the logistics industry has ushered in unprecedented business growth. A massive number of small parcels are frequently circulating in major logistics centers and express delivery outlets, placing extremely high demands on the efficiency and accuracy of parcel sorting. Small parcels are characterized by their small size and light weight, but their sheer quantity and variety make efficient and accurate sorting a crucial link in ensuring smooth logistics and improving customer satisfaction.

[0003] In existing traditional sorting lines, the weighing and scanning of packages are distributed across multiple independent workstations. Packages pass sequentially through weighing and scanning stations on the conveyor belt, with each station requiring specialized operators or equipment to complete a specific task. This step-by-step processing method causes packages to stop, wait, and be transferred multiple times throughout the sorting process, increasing sorting time.

[0004] While traditional robotic arms have improved automation to some extent in small parcel sorting, they still have significant shortcomings in weighing and scanning. After a traditional robotic arm picks up a parcel, it often needs to be transferred multiple times to different weighing and scanning devices. This multiple transfer not only increases the movement path and time cost of the robotic arm, but also easily leads to problems such as parcel displacement and collisions during the transfer process, affecting the accuracy of weighing and scanning.

[0005] Therefore, there is a need to provide an integrated robotic arm device for automatic weighing and barcode scanning of small packages. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] Example: An integrated robotic arm device for automatic weighing and barcode scanning of small packages, such as... Figures 1-4As shown, the device includes a support frame 1, a conveying assembly 2, a connecting frame 3, a controller 4, an electric slide rail 5, a base 6, a robotic arm body 7, grippers 8, a pressure sensor 9, a barcode scanner 10, a miniature weighing sensor 11, a display screen 12, a detection camera 13, a placement frame 14, and a guardrail 15. The support frame 1 serves as the basic support structure for the entire device. The conveying assembly 2 is horizontally mounted on the upper part of the support frame 1. The conveying assembly 2 is used for horizontal conveying of small items wrapped within the device. The conveying assembly 2 consists of two conveying wheels, a conveyor belt, and a rotary drive component. The two conveying wheels are rotatably connected to the upper left and right sides of the support frame 1, respectively. A rotary drive component is installed on the upper right front side of the support frame 1, and the rotary drive component is connected to the front end of the right-side conveying wheel. 1. A connecting frame 3 is symmetrically connected to the rear side. A controller 4 is installed on the top of the left connecting frame 3. The controller 4 is responsible for coordinating and controlling the operation of various components. The controller 4 is electrically connected to the conveying component 2. An electric slide rail 5 is installed horizontally between the two connecting frames 3. A base 6 is installed on the electric slide rail 5 via an electric slider. The robotic arm body 7 is installed on the base 6. The electric slide rail 5 drives the base 6 to move horizontally, thereby adjusting the horizontal position of the robotic arm body 7. The controller 4 is electrically connected to the robotic arm body 7. A gripper 8 is installed on the gripper end of the robotic arm body 7. The gripper 8 is the component that directly contacts the small package and performs the gripping function. The controller 4 is electrically connected to the gripper 8. Pressure sensors 9 are installed inside each gripper 8. Sensor 9 is used to detect the pressure exerted on the gripper 8 when grasping the package in real time. Controller 4 is electrically connected to pressure sensor 9. A barcode scanner 10 is installed on the outer side of the gripper end of the robotic arm body 7. Barcode scanner 10 is used to scan barcode or QR code information on the surface of the package. Controller 4 is electrically connected to barcode scanner 10. A miniature weighing sensor 11 is installed on the outer side of the gripper end of the robotic arm body 7. Miniature weighing sensor 11 is used to measure the weight of the package. Controller 4 is electrically connected to miniature weighing sensor 11. A display screen 12 is installed on the rear side of controller 4. Display screen 12 is electrically connected to pressure sensor 9, barcode scanner 10, and miniature weighing sensor 11. Display screen 12 is used to display the data collected by each sensor in real time. The system displays information such as package weight, barcode information, and pressure value, as well as image information captured by the detection camera 13. Operators can intuitively understand the operating status of the device and package information through the display screen 12, facilitating monitoring, debugging, and maintenance. A detection camera 13 is installed on the right front side of the controller 4. The detection camera 13 is used to monitor the position and posture of small packages on the conveying assembly 2 in real time. The detection camera 13 is electrically connected to the controller 4 and the display screen 12. The detection camera 13 is located above the conveying assembly 2. A placement frame 14 is connected to the top of the connecting frame 3 on the right side. The placement frame 14 is used to temporarily store packages that have been weighed. After the miniature weighing sensor 11 on the robotic arm body 7 finishes weighing...The robotic arm 7 places the package into the placement frame 14, then rotates 180 degrees to allow the barcode scanner 10 to scan the package within the frame. Guardrails 15 are connected to the front and rear sides of the top of the support frame 1 to prevent packages from falling off.

[0022] When the robotic arm automatic weighing and scanning integrated device is needed, first connect the device to the power supply to start its operation. Then, place the small packages to be processed sequentially at the starting end of the conveyor assembly 2. The rotation drive component in the conveyor assembly 2 will start working, driving the conveyor belt in the conveyor assembly 2 to transport the small packages to the right. During the transport process, the detection camera 13 can monitor the position, posture, and other information of the small packages on the conveyor assembly 2 in real time and transmit the collected image signals to the controller 4. The controller 4 analyzes and processes the images to determine whether the package has reached the appropriate position, that is, the position where the robotic arm can accurately grasp it. If the package has not reached the appropriate position, the controller 4 continues to control the operation of the conveyor assembly 2; if the package has reached the appropriate position, the controller 4 sends a stop signal to the conveyor assembly 2 to stop the conveyor belt.

[0023] According to the package position information fed back by the detection camera 13, the controller 4 controls the electric slide rail 5 to move the base 6, adjusts the horizontal position of the robotic arm body 7, so that the robotic arm gripper end is close to the package. The robotic arm body 7 adjusts the position and posture of the gripper according to the preset motion trajectory, so that the gripper 8 is aligned with the package.

[0024] The controller 4 controls the gripper 8 to close and grasp the package. During the grasping process, the pressure sensor 9 can detect the pressure on the gripper 8 in real time and transmit the pressure data to the controller 4. The controller 4 adjusts the gripping force of the gripper 8 according to the pressure data to ensure that the package is grasped stably and to avoid damaging the package due to excessive gripping force.

[0025] After the robotic arm grabs the package, the miniature weighing sensor 11 starts to work, measures the weight of the package, and transmits the weight data to the controller 4. The controller 4 stores and processes the weight data, and transmits the data to the display screen 12 for real-time display.

[0026] After weighing, the robotic arm 7 places the package in the placement frame 14. Then, the robotic arm 7 rotates 180 degrees so that the barcode scanner 10 faces the package in the placement frame 14. The barcode scanner 10 scans the barcode or QR code information on the package surface and transmits the scanned data to the controller 4. The controller 4 identifies and processes the barcode information, matches it with the order information in the logistics system, and completes the association of package information.

[0027] After scanning, according to the logistics sorting requirements, the controller 4 controls the robotic arm to take the package out of the placement box 14 and place it in the corresponding sorting area or the conveyor equipment of the next processing stage. The above steps are repeated to process the subsequent small packages in sequence.

[0028] Once the day's parcel processing tasks are completed, the operator can simply turn off the power to the robotic arm's automatic weighing and scanning integrated device.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
