[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] See Figure 1 As shown, a vision-guided robot depalletizing and palletizing machine provided in this embodiment of the present utility model includes: a conveyor belt 1; a robotic arm 2, disposed on one side of the conveyor belt 1, with a clamp 3 installed at the lower end of the robotic arm 2; a camera 4, which is a binocular camera, disposed above the robotic arm 2; and a control box 5, which is connected to the robotic arm 2 and the camera 4 via signals.

[0025] During operation, after the operator places the pallet at the depalletizing position, the camera takes a picture of the product and sends the result to robotic arm 2. After receiving the information, robotic arm 2 moves to the corresponding position, uses gripper 3 to pick up the box and place it on the conveyor belt. By recognizing and analyzing the shape, size, position and other attributes of the items, the robot can accurately locate and manipulate the items, increasing the robot's perception of the surrounding environment. It has advantages such as high precision, strong adaptability, high flexibility, high safety, good stability and high degree of automation, which can greatly improve production efficiency and quality. It should be noted that the process of identifying and analyzing the attributes of an item, such as shape, size, and position, is existing technology in this field. For example, existing patents such as CN118529506A "Control Method and System for Palletizing Robot Based on Image Recognition" and CN119399271A "Palletizing Positioning Recognition Method, Automated Palletizing Feeding Device and Cigarette Packaging Supply Line" disclose the identification and analysis of attributes such as shape, size, and position of an item. However, the identification and analysis of attributes such as shape, size, and position of an item is not a key improvement of this utility model, so it will not be elaborated here.

[0026] See Figure 1 As shown, in some embodiments, the robotic arm 2 is mounted on a guide device 6, which includes an X-axis guide rail 61, a Y-axis guide rail 62, and a Z-axis guide rail 63. The X-axis guide rail 61 is slidably mounted on the Z-axis guide rail 63, and the Y-axis guide rail 62 is slidably mounted on the X-axis guide rail 61. The robotic arm 2 is mounted on the Y-axis guide rail 62. The robotic arm 2 can move along the X-axis, Y-axis, and Z-axis, and is driven by a motor and transmitted by a synchronous pulley to realize movement actions, which facilitates position adjustment for depalletizing and stacking.

[0027] See Figure 1As shown, in some embodiments, a display 8 is provided on one side of the conveyor belt 1. The display 8 is signal-connected to the control box 5. The control box 5 is used for the integrated installation of electrical control components. The display 8 is connected to the camera 4 to display 3D camera image recognition information.

[0028] See Figure 2 As shown, in some embodiments, see Figure 1 As shown, in some embodiments, the robotic arm 2 is connected to the clamp 3 via a detachable mechanism 7. The clamp 3 can be detached from the robotic arm, so that different types of clamps 3 can be replaced according to the shape and size of the items, such as vacuum suction cups, robotic arms, etc., to realize automatic destacking and stacking of items of different shapes and sizes, which is highly flexible.

[0029] See Figure 2 As shown, in some embodiments, the detachable mechanism 7 includes: a mounting plate 71 with bolt holes, on which the clamp 3 is mounted; and a connecting plate 72 connected to the mounting plate 71 via a connecting rod 73. The connecting plate 72 is detachably mounted inside the robotic arm 2. Multiple detachable mechanisms 7 can be prepared before use, and different clamps 3 can be mounted on the mounting plate 71 of one detachable mechanism 7. When in use, the connecting plate 72 on the corresponding clamp 3 can be directly installed inside the robotic arm 2, which is convenient and quick to install.

[0030] See Figure 2 As shown, in some embodiments, a limiting block 74 is installed at the lower end of the robotic arm 2. The limiting block 74 includes two movable blocks connected by hinges, and a limiting hole 75 is formed between the two movable blocks. The connecting rod 73 is accommodated in the limiting hole 75. The two movable blocks are locked together by bolts 76. By using the limiting hole 75 to lock the connecting rod 73, the movement of the clamp 3 can be reduced while the clamp 3 is installed on the robotic arm 2, thus ensuring the stability of the clamp 3 during operation.

[0031] See Figure 2 As shown, in some embodiments, the diameter of the connecting plate 72 is larger than the diameter of the limiting hole 75. After the connecting plate 72 is installed into the robotic arm 2, the connecting plate 72 can be restricted above the limiting block 74 by the blocking of the limiting block 74, thereby reducing the movement of the clamp 3.

[0032] See Figure 2 As shown, in some embodiments, the robotic arm 2 has a mounting hole 21 inside, the diameter of the connecting plate 72 is equal to the diameter of the mounting hole 21, and the outer wall of the connecting plate 72 abuts against the inner wall of the mounting hole 21, further reducing the shaking of the clamp 3 and ensuring stability.

[0033] See Figure 2As shown, in some embodiments, the thickness of the limiting block 74 is equal to the length of the connecting rod 73, which can just restrict the limiting block 74 between the mounting plate 71 and the lower end face of the robotic arm 2, thereby limiting the movement of the clamp and preventing it from moving up and down.

[0034] By recognizing and analyzing the shape, size, and position of items, the robot can accurately locate and manipulate them, achieving higher precision requirements. It can adapt to items of different shapes and sizes without requiring fixed shapes or dimensions. Through program modification and parameter adjustment, it can automatically depalletize and stack items of different shapes and sizes, offering high flexibility. Operators do not need to enter the robot's work area, avoiding safety hazards caused by operator error. The depalletizing and stacking processes are completed autonomously by the robot, avoiding the instability of manual operation and making the task more stable and reliable. The depalletizing and stacking processes are largely automated, requiring no human intervention, reducing labor intensity and human resource costs.
