[0031] The robotic arm includes a robotic arm control box 1. At the bottom inside the robotic arm control box 1, there is a movable chassis 2. At the top of the movable chassis 2, a plurality of first hydraulic cylinders 3 are connected. One end of the first hydraulic cylinder 3 is fixedly connected to the robotic arm control box 1 through bolts, and the other end is fixedly connected to the movable chassis 2 through bolts. At the bottom of the movable chassis 2, a plurality of universal wheels 4 are connected.
[0032] In the present invention, the first hydraulic cylinder 3 can push the movable chassis 2 inside the robotic arm control box 1, and can push the bottom of the movable chassis 2 out through the inside of the robotic arm control box 1, so that the universal wheels 4 are in contact with the ground, and the robotic arm control box 1 is lifted, and the robotic arm is lifted. Or the movable chassis 2 and the universal wheels 4 are pulled back into the inside of the robotic arm control box 1, so that the robotic arm control box 1 stands on the ground, and the movement of the robotic arm can be avoided.
[0033] As Figure 1 and Figure 2 shown, at the top inside the robotic arm control box 1, there are a first motor 5 and a support base 6. The first motor 5 is installed inside the robotic arm control box 1 by bolts. At the top of the support base 6, there is a mounting base plate 7 fixed. At the top of the mounting base plate 7, there is a connecting chassis 8 installed by bolts. Above the connecting chassis 8, there is a first robotic arm 10. A shaft rod passes through the bottom of the first robotic arm 10, and the shaft rod is fixedly connected to the bottom of the first robotic arm 10. The input shaft of the shaft rod is connected to a second motor 9, and the second motor 9 is installed on one side of the connecting chassis 8 by bolts.
[0034] In the present invention, the first motor 5 drives the support base 6 and the mounting base plate 7 to rotate, which can change the steering angle of the robotic arm and adjust the robotic arm to a suitable position. Then, the second motor 9 drives the first robotic arm 10 to rotate, which can change the rotation angle of the first robotic arm 10 and adjust the first robotic arm 10 to a suitable inclined position.
[0035] As Figure 1 shown, at the top of the first robotic arm 10, there is a movable seat 11. An activity shaft passes through the inside of the movable seat 11, and the activity shaft is fixedly connected to the movable seat 11. The input shaft of the activity shaft is connected to a third motor 12, and the third motor 12 is installed on the first robotic arm 10 by bolts.
[0036] In the present invention, the third motor 12 can drive the movable seat 11 and the second robotic arm 13 to rotate, which can change the rotation angle of the second robotic arm 13 and adjust the second robotic arm 13 to a suitable inclined position.
[0037] As Figure 1 and Figure 3 shown, the movable seat 11 is fixedly connected to a second robotic arm 13. Inside the second robotic arm 13, there is a second hydraulic cylinder 14. One end of the second hydraulic cylinder 14 is installed inside the second robotic arm 13 by bolts, and the other end is connected to a movable arm 15.
[0038] In the present invention, the second hydraulic cylinder 14 can push the movable arm 15 to move, so that the movable arm 15 moves along the central axis direction of the second robotic arm 13, and the extension length of the movable arm 15 can be controlled.
[0039] As Figure 1 and Figure 4As shown, one end of the movable arm 15 is bolted with a motor box 16. Inside the motor box 16, a fourth motor 17 is bolted. The output shaft of the fourth motor 17 is connected to a movable plate 18.
[0040] In the present invention, the fourth motor 17 can drive the rotation angle of the movable plate 18 to change the position of the wire harness fixing block 19 on the movable plate 18.
[0041] As Figure 5 shown, a wire harness fixing block 19 is arranged on one side of the movable plate 18.
[0042] As Figure 1 and Figure 5 shown, a chute 21 is formed inside the movable plate 18. Inside the chute 21, a bidirectional lead screw 22 is arranged. The input shaft of the bidirectional lead screw 22 is connected to a fifth motor 23. The fifth motor 23 is bolted on the movable plate 18. Clamping plates 26 are arranged on both sides of the wire harness fixing block 19. An active slider 24 is fixed to the clamping plate 26. The active slider 24 is locally adapted to the chute 21 and is slidably connected. A lead screw sleeve 25 is embedded inside the active slider 24. The lead screw sleeve 25 is in threaded cooperation with the bidirectional lead screw 22.
[0043] In the present invention, the wire harness fixing block 19 can be installed on the movable plate 18. The fifth motor 23 drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 can push the two lead screw sleeves 25 and the active sliders 24 towards each other inside the chute 21. Since the active slider 24 is fixedly connected to the clamping plate 26, the two clamping plates 26 can clamp the wire harness fixing block 19, and the wire harness fixing block 19 and the infrared camera 20 are installed on the movable plate 18.
