[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-2 This utility model provides a multi-arm rotary handling robot arm, comprising:

[0029] Base 1, on which a fixing component is installed;

[0030] Multi-degree-of-freedom robotic arm 2 is horizontally connected to the top of base 1 via a rotating assembly;

[0031] An angle adjustment component is installed at the end of the multi-degree-of-freedom robotic arm 2;

[0032] The mechanical gripper is mounted on an angle adjustment assembly. The mechanical gripper includes a mounting frame 3, on which a lifting frame 4 is vertically slidably connected. A lifting assembly is mounted on the mounting frame 3. The lifting assembly is used to control the lifting of the lifting frame 4. A clamping assembly and a spacing adjustment assembly are provided on the lifting frame 4. The clamping assembly is symmetrically slidably connected to the lifting frame 4. The spacing adjustment assembly is used to adjust the distance between the two clamping assemblies.

[0033] The control system, multi-degree-of-freedom robotic arm 2, angle adjustment component, rotation component, lifting component, spacing adjustment component, and clamping component are all connected to the control system.

[0034] When this invention is in operation, if an object needs to be moved, the entire robotic arm system is first activated by the control system. The control system, by controlling the rotating component and the multi-degree-of-freedom robotic arm 2, precisely positions the robotic gripper above the object to be moved. The flexibility of the multi-degree-of-freedom robotic arm 2 allows for complex movements in three-dimensional space to adapt to different working environments and object positions. After approaching the object, the angle adjustment component starts working, adjusting the tilt angle of the robotic gripper according to the shape, size, and handling requirements of the object, ensuring that the robotic gripper can contact the object in the most suitable posture. The control system then activates the lifting component, driving the lifting mechanism via a motor or hydraulic device. The frame 4 moves vertically on the mounting frame 3, bringing the gripping components close to the object. Once the gripping components contact the object, the spacing adjustment component starts working, adjusting the distance between the two gripping components according to the width or diameter of the object to ensure that they can grip the object tightly and evenly. After successfully gripping the object, the control system uses the rotating component and the multi-degree-of-freedom robotic arm 2 to transport the object to the target position. After reaching the target position, the lifting component starts again to lower the object to an appropriate height. Then, the spacing adjustment component releases the gripping components and releases the object. After completing the transport task, the robotic gripper returns to the initial position or standby position, ready for the next transport.

[0035] Further optimization of the scheme: the rotating component includes a rotary motor, a turntable 5 is fixedly connected to the bottom of the multi-degree-of-freedom robotic arm 2, the turntable 5 is rotatably connected to the top surface of the base 1, the rotary motor is fixed on the base 1, the output shaft of the rotary motor is fixedly connected to a drive gear, and the outer wall of the turntable 5 is provided with tooth grooves, and the drive gear meshes with the tooth grooves.

[0036] When the control system receives a handling command, it first starts the rotary motor in the rotating assembly. At this time, the rotary motor is stationary, and the drive gear on its output shaft is either not engaged or about to engage with the toothed groove on the outer wall of the turntable 5. The turntable 5 is rotatably connected to the top surface of the base 1 through some means (such as bearings), ensuring that the turntable 5 can rotate smoothly. As the rotary motor starts, its output shaft begins to rotate, driving the drive gear to rotate as well. Because the drive gear matches the toothed groove design on the outer wall of the turntable 5, the continuous rotation of the rotary motor is transmitted to the turntable 5 through the drive gear, causing the turntable 5 to rotate on the top surface of the base 1 in a predetermined direction and speed. The rotation of the turntable 5 will drive the multi-degree-of-freedom robotic arm 2, which is fixedly connected to it, to rotate as well. The multi-degree-of-freedom robotic arm 2, through its internal joints and drive mechanism, can perform complex spatial movements such as pitch, yaw, and roll while rotating, in order to achieve precise positioning and handling of objects at different positions and angles.

[0037] Further optimization of the scheme: the angle adjustment component includes an angle adjustment motor 6, which is installed at the end of the multi-degree-of-freedom robotic arm 2, and the mounting bracket 3 is fixedly connected to the angle adjustment motor 6.

[0038] The scheme is further optimized. The lifting component includes a lifting motor 7, which is fixedly connected to the lifting frame 4. The output shaft of the lifting motor 7 is fixedly connected to a lifting gear. A toothed plate is vertically fixedly connected to the mounting frame 3, and the lifting gear meshes with the toothed plate.

[0039] The mounting frame 3 and the lifting frame 4 slide vertically together, and the two adopt a plate-slot cooperation method (rail and slide plate cooperation). The lifting frame 4 has a through slot, and the mounting frame 3 has an installation slot. The toothed plate is installed in the installation slot. The lifting gear extends through the through slot and meshes with the toothed plate in the installation slot. The lifting motor 7 drives the lifting gear to rotate, so as to realize the climbing and lifting of the lifting frame 4.

[0040] The scheme is further optimized. The spacing adjustment component includes a spacing adjustment motor 8, which is fixedly connected to the lifting frame 4. The output shaft of the spacing adjustment motor 8 is fixedly connected to a bidirectional screw 9, which is rotatably connected to the lifting frame 4. A slider 10 is horizontally slidably connected to the lifting frame 4. The bidirectional screw 9 passes through the slider 10 and is threadedly connected to the slider 10. The clamping component is installed on the slider 10.

[0041] Further optimization of the scheme: the clamping assembly includes a side plate 11, which is symmetrically fixedly connected to both sides of the slider 10. The upper and lower ends of any side plate 11 are respectively rotatably connected to a gripper 12. An electrically controlled push rod 13 is fixedly connected to the back side of the slider 10. The output shaft of the electrically controlled push rod 13 is fixedly connected to a push rod 13. The push rod 13 and the electrically controlled push rod 13 are vertically arranged. Two sets of connecting rods 14 are respectively rotatably connected to both ends of the push rod 13. The connecting rods 14 are rotatably connected to the middle position of the gripper 12.

[0042] When no spacing adjustment command is received, the spacing adjustment motor 8 is stationary, and the bidirectional screw 9 is also stationary. At this time, the slider 10 remains in a fixed position on the lifting frame 4, and the grippers 12 of the clamping assembly are open, ready to receive the object. When the control system receives a spacing adjustment command, it starts the spacing adjustment motor 8. The output shaft of the spacing adjustment motor 8 begins to rotate, driving the bidirectional screw 9 to rotate as well. Since the bidirectional screw 9 and the slider 10 are threadedly connected, and the slider 10 is horizontally slidably connected on the lifting frame 4, the rotation of the bidirectional screw 9 causes the slider 10 to move to the sides or center on the lifting frame 4. After the clamping assembly is adjusted to the appropriate position, the control system starts the electrically controlled push rod 13. The output shaft of the electrically controlled push rod 13 begins to extend or retract, driving the push rod 13 to move as well. Because the push rod 13 and the electrically controlled push rod 13 are vertically positioned, and both ends of the push rod 13 are rotatably connected to the gripper 12 at the middle position via connecting rods 14, the movement of the push rod 13 causes the gripper 12 to rotate around its upper and lower ends, thus closing or opening the gripper 12. After successfully gripping an object, the multi-arm rotary handling robot will transport the object to the target position according to a predetermined path and speed. Upon reaching the target position, the electrically controlled push rod 13 will restart, causing the gripper 12 to open and release the object. Then, components such as the spacing adjustment motor 8 and the lifting assembly will reset and standby according to a predetermined program, awaiting the next handling command.

[0043] The movement of slider 10 causes side plate 11 and clamping components to move together, thereby changing the distance between the two clamping components. This process can be precisely adjusted according to the width or diameter of the object, ensuring that the clamping components can grip the object tightly and evenly. The flexibility of the spacing adjustment component and the clamping components allows the multi-arm rotary handling robot to adapt to objects of different shapes, sizes, and weights, improving the system's versatility and adaptability.

[0044] The solution is further optimized by setting several sets of fixing components on the base 1. The fixing components include fixing seats 15, which are fixed to the bottom side of the base 1 and are equipped with fixing bolts.
