[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a positioning and gripping robotic arm, including a robotic arm body 1, a base 2 mounted on the surface of the robotic arm body 1, and a protective device 3 provided on the surface of the robotic arm body 1. By setting the protective device 3, the connection holes on the surface of the robotic arm body 1 can be protected, avoiding the situation where dust and other impurities adhere to the surface of the connection holes of the robotic arm body 1 after a long period of non-use, resulting in poor contact of the connection holes and causing the connection holes of the robotic arm body 1 to malfunction, thus improving the practicality of the equipment. The surface of the base 2 is provided with a disassembly device 4, which facilitates the disassembly of the robotic arm body 1 by the operator. This avoids the situation where the robotic arm body 1 is fixed by bolts in the traditional way, which makes disassembly time-consuming and laborious for the operator, resulting in low disassembly efficiency, thus improving the disassembly efficiency of the operator.
[0030] The specific design and function of its protective device 3 and disassembly device 4 will be explained below.
[0031] Reference Figure 2 and, 3 and Figure 4As shown in this embodiment: the protective device 3 includes a shaped block 301, which is fixedly connected to the surface of the robot body 1. A rotating rod 302 is rotatably connected to the surface of the shaped block 301. A protective plate 303 is fixedly connected to the arc surface of the rotating rod 302. A fixing block 304 is fixedly connected to the surface of the robot body 1. A fixing rod 305 is fixedly connected to the surface of the fixing block 304. A blocking block 308 is fixedly connected to the end of the fixing rod 305 away from the fixing block 304. An operating plate 306 is slidably connected to the arc surface of the fixing rod 305. A plug rod 307 is fixedly connected to the surface of the operating plate 306 near the fixing block 304. A slot is provided on the surface of the protective plate 303. When the operator needs to use the protective plate 303 to protect the robot body 1... When protecting the surface connection holes, rotating the protective plate 303 causes the rotating rod 302 to rotate. When the surface of the protective plate 303 contacts the fixing block 304, the insertion rod 307 is located directly in front of the slot of the protective plate 303. Pushing the operating plate 306 causes the insertion rod 307 to move. When the insertion rod 307 is inserted into the surface of the slot of the protective plate 303, the insertion rod 307 fixes the protective plate 303. At this time, the protective plate 303 can protect the connection holes on the surface of the robot body 1, achieving the effect of fixing the protective plate 303. This avoids the robot body 1 from shaking too much during operation, which could cause the protective plate 303 to open passively, resulting in a reduction in the protective effect of the protective plate 303. A placement slot is provided on the side of the protective plate 303 near the fixing block 304. A protective pad 309 is fixedly connected to the surface of the placement slot of the protective plate 303. When the operator rotates the protective plate 303, the protective plate 303 drives the rotating rod 302 to rotate, which in turn drives the protective pad 309 to rotate. When the protective pad 309 contacts the surface of the fixing block 304, the insertion rod 307 is located directly in front of the slot of the protective plate 303. At this time, the operator can push the operating plate 306 to move the insertion rod 307 until the insertion rod 307 is inserted into the surface of the slot of the protective plate 303. The protective pad 309 achieves the effect of shock absorption and protection, avoiding repeated contact and collision between the protective plate 303 and the fixing block 304, thus preventing the protective plate 303 from being easily damaged. The rotating rod 302... Two torsion springs 310 are fitted onto the arc-shaped surface of the robot body 1. The two ends of each torsion spring 310 are fixedly connected to the irregularly shaped block 301 and the protective plate 303, respectively. When the operator needs to use the connection holes on the surface of the robot body 1, the protective plate 303 can be opened, and the operating plate 306 can be pulled. The operating plate 306 moves the insertion rod 307. When the insertion rod 307 is completely disengaged from the surface of the slot in the protective plate 303, the insertion rod 307 contacts the fixing point to the protective plate 303. The torque of the torsion springs 310 causes the protective plate 303 to rotate, which in turn causes the rotating rod 302 to rotate until the protective plate 303 is fully opened. At this point, the operator can normally use the connection holes on the surface of the robot body 1. The torque of the torsion springs 310 achieves the effect of automatically opening the protective plate 303.Simultaneously, the protective plate 303 remains open, thus facilitating the use of the connection holes on the surface of the robotic arm body 1 by the operator.
[0032] Reference Figure 5 and Figure 6 As shown, specifically, the disassembly device 4 includes a base plate 41. The surface of the base 2 is slidably connected to the base plate 41. Two square rods 42 are fixedly connected to the surface of the base plate 41. Two sliding rods 43 are slidably inserted into the square rods 42. One end of each sliding rod 43 is fixedly connected to an L-shaped block 44, which is slidably connected to the surface of the base plate 41. A handle 45 is fixedly connected to the end of each sliding rod 43 away from the L-shaped block 44. A square block 46 is fixedly connected to the surface of the handle 45. A limiting rod 47 is slidably inserted into the square block 46. Two limiting grooves are formed on the surface of the base plate 41. When the operator needs to disassemble the robot body 1, the handle 47 is pulled. 5. The handle 45 moves the sliding rod 43, which in turn moves the L-shaped block 44. When the handle 45 moves to the appropriate position, the limiting rod 47 is directly above the limiting groove of the base plate 41. The limiting rod 47 slides downward under the influence of gravity until it inserts into the surface of the limiting groove of the base plate 41. At this point, the L-shaped block 44 is completely detached from the surface of the base 2. The operator can then disassemble the robot body 1 together with the base 2. Moving the base 2 causes the robot body 1 to move. When the base 2 is completely detached from the surface of the base plate 41, the operator can perform maintenance on the robot body 1. The limiting rod 47 has achieved its intended function. The L-shaped block 44 is fixed to prevent it from sliding, making it easier for workers to disassemble the base 2. A spring 48 is fitted onto the arc surface of the sliding rod 43, with both ends of the spring 48 fixedly connected to the square rod 42 and the handle 45, respectively. When workers need to repair the robotic arm body 1, they can disassemble the robotic arm body 1 together with the base 2. Pulling the handle 45 stretches the spring 48, causing the handle 45 to move the sliding rod 43, which in turn moves the L-shaped block 44. When the L-shaped block 44 is completely detached from the surface of the base 2, workers can then disassemble the robotic arm body 1 together with the base 2 for further processing. After maintenance, the robot body 1 and base 2 are moved back to their original positions. The limit rod 47 is pulled. When the limit rod 47 is completely disengaged from the surface of the limit groove of the base plate 41, the limit rod 47 releases the fixation of the handle 45. The rebound force of the spring 48 drives the handle 45 to move. The handle 45 drives the sliding rod 43 to move. The sliding rod 43 drives the L-shaped block 44 to move until the L-shaped block 44 moves to the surface of the base 2. The rebound force of the spring 48 achieves the effect of automatically moving the L-shaped block 44 back. At the same time, it can limit the movement of the handle 45 and the sliding rod 43, and the movement of the L-shaped block 44, thus improving the stability of the L-shaped block 44 when it is fixed to the base 2.
[0033] Working principle: When the operator needs to protect the connection holes on the surface of the robot body 1 using the protective plate 303, rotating the protective plate 303 causes the rotating rod 302 to rotate, which in turn causes the protective pad 309 to rotate. When the protective pad 309 contacts the surface of the fixing block 304, the insertion rod 307 is positioned directly in front of the slot in the protective plate 303. Pushing the operating plate 306 causes the insertion rod 307 to move. When the insertion rod 307 is inserted into the surface of the slot in the protective plate 303, it fixes the protective plate 303 in place. At this time, the protective plate 303 can protect the connection holes on the surface of the robot body 1. When the operator needs to access the connection holes on the surface of the robot body 1, the protective plate 303 can be opened. Pull the operating plate 306, which moves the insertion rod 307. When the insertion rod 307 is completely disengaged from the surface of the slot in the protective plate 303, it contacts the fixing of the protective plate 303. The torque of the torsion spring 310 drives the protective plate 303 to rotate, which in turn drives the rotating rod 302 to rotate until the protective plate 303 is fully opened. At this point, the operator can use the connection holes on the surface of the robot body 1 normally. This achieves the effect of protecting the connection holes on the surface of the robot body 1, preventing dust and other impurities from adhering to the surface of the connection holes after a long period of non-use, which could lead to poor contact and cause the connection holes to malfunction.
[0034] When the operator needs to repair the robotic arm body 1, the robotic arm body 1 can be disassembled together with the base 2. Pulling the handle 45 stretches the spring 48, causing the handle 45 to move the sliding rod 43, which in turn moves the L-shaped block 44. When the handle 45 moves to the appropriate position, the limiting rod 47 is directly above the limiting groove of the base plate 41. The limiting rod 47 slides downward under the influence of gravity until it inserts into the surface of the limiting groove of the base plate 41. At this point, the L-shaped block 44 is completely detached from the surface of the base 2. The operator can then disassemble the robotic arm body 1 together with the base 2, move the base 2, and the base 2 will move the robotic arm body 1 until the base 2 is completely detached from the surface of the base plate 41. The operator can then repair the robotic arm body 1. After maintenance of the robot body 1 is completed, the robot body 1 and base 2 are moved back to their original positions. The limit rod 47 is pulled. When the limit rod 47 is completely disengaged from the surface of the limit groove of the base plate 41, the limit rod 47 releases the fixation of the handle 45. The rebound force of the spring 48 drives the handle 45 to move. The handle 45 drives the sliding rod 43 to move. The sliding rod 43 drives the L-shaped block 44 to move until the L-shaped block 44 moves to the surface of the base 2. The L-shaped block 44 fixes the base 2. At this time, it achieves the effect of facilitating the disassembly of the robot body 1 by the staff. This avoids the situation where the robot body 1 is fixed by bolts when it malfunctions, which is time-consuming and laborious for the staff to disassemble the robot body 1, resulting in low disassembly efficiency.
