[0002] A robotic arm is an automated mechanical device controlled by a program. It typically consists of a base, joints, a drive unit, and an end effector. It is widely used in manufacturing, logistics and warehousing and other fields. By receiving instructions, the robotic arm can accurately position itself at a point in three-dimensional (or two-dimensional) space to perform fine operations such as grasping, handling, and assembly.

[0003] AGV robots are increasingly used in factory logistics. Traditional AGVs mainly complete the function of transporting goods, but in modern intelligent manufacturing scenarios, it is often necessary to complete simple operations such as grasping and placing during transportation. This requires equipping AGVs with robotic arms. The combination of robotic arms and AGV robots can grasp and move packages in warehouses, replacing manual handling.

[0004] In the existing technology, the connection between the robotic arm and the AGV is usually fixed with bolts. Although this method allows for flexible disassembly of the robotic arm, bolt connection not only requires special tools, but also takes a long time to install, thus making it impossible to quickly assemble and disassemble the robotic arm.

[0023] Example 1

[0024] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a robot-based quick-assembly robotic arm, including a robotic arm assembly 100, a base 110, and a fixing mechanism 200, including a base 210 located at the bottom of the base 110, a fixing component 220 for connecting the base 210 and the base 110, and limiting holes 230 and limiting posts 240 for limiting the base 210 and the base 110. The fixing component 220 is provided in four sets, respectively located around the surface of the base 110. The fixing component 220 includes... The screw 221 includes a threaded hole 222 on the surface of the base 210, an external thread 223 on the lower end of the surface of the screw 221, an upper washer 224 on the top of the screw 221, a thrust washer 225 on the top of the upper washer 224, a cam handle 226 on the upper end of the thrust washer 225, a lower washer 227 and a spring 228 sleeved on the surface of the screw 221. The lower end of the screw 221 passes through the base 110 and extends into the inner cavity of the threaded hole 222. The external thread 223 is threadedly connected to the inner cavity of the threaded hole 222.

[0025] like Figure 1-4As shown, the quick-change connector 130 and the gripper 140 can be easily connected to replace different grippers 140 according to usage requirements, thus adapting to different task needs. The four sets of fixing components 220, together with the limiting holes 230 and the limiting posts 240, enable quick fixing and disassembly of the robotic arm assembly 100. The fixing components 220 are a combination of screw 221 and threaded hole 222, cam handle 226, spring 228 and multiple sets of washers. By rotating the cam handle 226, the screw 221 is locked or released, thus achieving tool-free quick locking. The limiting post 230 and the limiting hole 240 cooperate to ensure that the base 210 and the base 110 are accurately aligned, avoiding installation deviation. The buffer pad 250 provides buffer protection during installation, while enhancing the tightness between the mounting surfaces and improving overall stability. This effectively solves the problems of traditional bolt connection methods in terms of disassembly and assembly efficiency, tool dependence and ease of operation.

[0026] Example 2

[0027] Reference Figure 1 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] In this embodiment, the robotic arm assembly 100 also includes an arm 120 located at the upper end of the base 110, a quick-change connector 130 located at the end of the arm 120, and a gripper 140 movably connected to the quick-change connector 130.

[0029] The boom 120 consists of at least three booms 120, and each boom 120 is movably connected by a joint. The boom 120 is located on top of the base 110 and is rotatably connected to the base 110. The quick-connect joint 130 is fixed to the end of the boom 120 by bolts, and the gripper 140 is inserted into the quick-connect joint 130.

[0030] like Figure 1As shown, the gripper 140 is designed as a replaceable module to adapt to the gripping needs of workpieces of different shapes and sizes. The gripper 140 can be equipped with sensors to monitor the gripping force in real time, ensuring the stability and safety of the workpiece during handling. During the operation of the robotic arm assembly 100, the arm 120 achieves multi-degree-of-freedom operation through the flexible rotation of its joints, greatly improving the flexibility and applicability of the robotic arm. The quick-change connector 130 not only ensures the rapid replacement of the gripper 140 but also guarantees the stability of the connection through bolt fixing, preventing damage during operation. In the event of an unexpected situation caused by loose connection during the process, the base 110, as the supporting foundation of the robotic arm, is connected to the base 210 through the fixing mechanism 200, ensuring that the entire robotic arm remains stable during movement or operation. Moreover, the base 110 adopts a rotating structure, which can work in conjunction with the arm 120 to achieve all-round and multi-angle operation, enhancing the flexibility and work efficiency of the robotic arm. In addition, the rotating structure design of the base 110 allows the robotic arm to flexibly turn and adjust in the horizontal and vertical planes, further expanding its operating range and application scenarios.

[0031] Example 3

[0032] Reference Figure 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, the upper washer 224 is fixedly connected to the screw 221, the thrust washer 225 is fixed to the top of the upper washer 224, the cam handle 226 is movably connected to the thrust washer 225 through a rotating shaft, one end of the spring 228 is fixedly connected to the fixing component 220, the other end of the spring 228 contacts the bottom of the upper washer 224, and the bottom of the lower washer 227 contacts the surface of the base 110.

[0034] The fixing mechanism 200 also includes a limiting hole 230 opened at the bottom of the base 110, a limiting post 240 fixed at the top center of the base 210, and a buffer pad 250 sleeved on the surface of the limiting post 240.

[0035] The end of the limiting post 240 away from the base 210 extends into the inner cavity of the limiting hole 230 and is movably connected to the inner cavity of the limiting hole 230. The bottom and top of the buffer pad 250 contact the top of the base 210 and the bottom of the limiting hole 230, respectively.

[0036] It also includes an AGV trolley 300, with a base 210 fixed to the top of the AGV trolley 300 by bolts.

[0037] like Figure 2-4As shown, when the robotic arm assembly 100 needs to be installed on the AGV trolley 300, firstly, the base 210 is fixed to the top of the AGV trolley 300 with bolts. Then, the limiting hole 230 at the bottom of the base 110 is aligned with the limiting post 240 at the center of the top of the base 210, and the base 110 is moved downward until the limiting post 240 is fully inserted into the limiting hole 230. At this time, the bottom and top of the buffer pad 250 contact the top of the base 210 and the bottom of the limiting hole 230, respectively, providing buffer protection during installation and enhancing the tightness between the mounting surfaces. Next, the cam handle 226 in the four sets of fixing components 220 is rotated, thereby driving the screw 221 to move downward in the threaded hole 222 until the lower pad... The bottom of plate 227 is in close contact with the surface of base 110. Then, the cam handle 226 is pressed down. At this time, the spring 228 is in a compressed state, providing a downward preload to ensure a stable connection between the screw 221 and the threaded hole 222. When the robotic arm assembly 100 needs to be disassembled, simply place the cam handle 226 on the upper part and then rotate the cam handle 226 in the opposite direction to easily loosen the screw 221, thus achieving quick disassembly of the robotic arm assembly 100. By adopting the fixing mechanism 200, including the base 210, fixing component 220, and the cooperation of limiting hole 230 and limiting post 240, the quick installation and disassembly of the robotic arm assembly 100 on the AGV trolley 300 is realized, improving the installation efficiency and operation convenience of the robotic arm.

[0038] In use, the robotic arm assembly 100 mainly consists of a base 110, an arm 120, a quick-connect coupling 130, and a gripper 140, and is responsible for performing tasks such as grasping, handling, and assembly. The fixing mechanism 200 is used to securely install the robotic arm assembly 100 onto the AGV trolley 300. The fixing mechanism 200 includes a base 210, a fixing component 220, a limiting hole 230, a limiting post 240, and a buffer pad 250. The AGV trolley 300 serves as the mobile platform for the robotic arm, enabling flexible deployment and spatial transfer of the robotic arm. The base 110 serves as the supporting foundation for the robotic arm and is connected to the base 210 through the fixing mechanism 200 to ensure that the entire robotic arm remains stable during movement or operation.

[0039] The base 210 is fixed to the top of the AGV trolley 300 with bolts. Then, the limiting hole 230 at the bottom of the base 110 is aligned with the limiting post 240 at the center of the top of the base 210, and the base 110 is moved downward until the limiting post 240 is fully inserted into the limiting hole 230. The bottom and top of the buffer pad 250 contact the top of the base 210 and the bottom of the limiting hole 230, respectively. Then, the cam handle 226 in the four sets of fixing components 220 is rotated to make the screw 221 engage with the threaded hole 222, completing the quick installation of the robotic arm component 100. The upper washer 224 and the thrust washer 225 together form a locking structure. The cam handle 226 controls the locking and releasing states through the rotating shaft. The spring 228 provides preload to prevent the screw 221 from loosening and improve the reliability of the connection. Quick disassembly and assembly can be achieved by rotating the cam handle 226, thereby improving maintenance and replacement efficiency.
