Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] With the advancement of science and technology, there are more and more automated robots with more and more extensive functions. In the industrial manufacturing process, in order to save manpower and improve production efficiency, intelligent manipulators have emerged. Manipulators are automatic operating devices that can imitate certain movements and functions of human hands and arms to grasp, carry, flip objects or operate tools according to fixed procedures, greatly improving production efficiency.

[0027] See also Figure 1-Figure 4 As shown, this embodiment provides an adjustable intelligent robotic arm, including a base 1, a rotating structure 2 is fixedly connected to the upper surface of the base 1 near the center, a protective shell 11 is fixedly connected to the upper surface of the rotating structure 2 near the outer edge, a large arm 12 is connected above the protective shell 11, and a lateral adsorption component 3 is fixedly connected to the other end of the large arm 12. The grasping position is adjusted by the lateral adsorption component 3, and at the same time, different grasping objects are grasped more forcefully by the lateral adsorption component 3.

[0028] The improvement of this embodiment is that: the mechanical arm can rotate in multiple directions through the rotating structure 2, and the mechanical arm is limited by the limit block 21 to avoid the mechanical arm being unable to be fixed when rotating. At the same time, the graspable position is adjusted by the lateral adsorption component 3, eliminating the trouble of fixing the position of the object. At the same time, the lateral adsorption component 3 is used to grasp objects of different shapes to avoid the possibility of falling during the grasping process.

[0029] Taking into account that the grasping position of the robot arm is limited when grasping an object, it needs to be fixed in position to grasp, which greatly affects the efficiency. Therefore, the lateral adsorption component 3 includes a limit frame 31, and the outer wall of the limit frame 31 is fixedly connected to the end of the upper arm 12. Slide bars 34 are fixedly connected on both sides of the limit frame 31. The slide bars 34 are slidably connected to the inside of the forearm 33. The forearm 33 is used to slide over the slide bar 34 to increase the grasping range of the robot arm and improve efficiency.

[0030] Taking into account that it is difficult to recover the robotic arm during grasping, a connecting plate 36 is fixedly connected to the other end of the forearm 33, a hydraulic rod 37 is fixedly connected to the connecting plate 36 near the center, the output end of the hydraulic rod 37 is fixedly connected to the inside of the connecting disk 38, a mechanical claw 39 is fixedly connected to the lower surface of the connecting disk 38, the support arm at the upper end of the mechanical claw 39 is connected to the output end of the hydraulic rod 37, and the output end of the hydraulic rod 37 is used to move forward to drive the mechanical claw 39 to grasp.

[0031] Taking into account that the mechanical claw 39 may fall off due to the different shapes of the objects when grasping, a plurality of suction cups 35 are provided on the inner surface of the mechanical claw 39, and the adsorption force of the plurality of suction cups 35 is utilized to clamp and adsorb objects of different shapes to avoid the possibility of falling during the grasping process.

The limiting groove 320 is matched with the limiting ball 321. The forearm 33 is limited by the overlap of the limiting groove 320 inside the forearm 33 and the limiting ball 321. At the same time, the elastic member 322 below the limiting ball 321 enables the forearm 33 to move over the sliding rod 34 through external force.

[0033] Considering that if the bottom of the robotic arm cannot rotate, its working range will be greatly limited, which means that the robotic arm can only move and operate within a fixed plane or space and cannot cover a wider area. Therefore, the rotating structure 2 includes a rotating outer ring 24, and the bottom of the rotating outer ring 24 is fixedly connected to the base 1. The inner wall of the rotating outer ring 24 is fixedly connected with a plurality of clamping plates 23, and the clamping plates 23 are rotatably connected to the limit block 21.

[0034] The utility model is used for an adjustable intelligent mechanical arm device. When it is used, the rotating structure 2 above the base 1 drives the arm 12 to rotate. The rotating structure 2 includes a rotating outer ring 24. The inner wall of the rotating outer ring 24 is provided with a plurality of clamping plates 23. The clamping plates 23 clamp the limit block 21. The other end of the limit block 21 is connected to the gear plate 22. At the same time, a plurality of elastic plates 25 are also provided on the inner wall of the rotating outer ring 24. The outer side of the elastic plate 25 fits the limit block 21, so that the arm 12 can move in one direction above the base 1. The lateral adsorption component 3 connected to the upper end of the arm 12 includes A limit frame 31 is provided with slide bars 34 on both sides of the limit frame 31. The slide bars 34 are slidably connected to the inside of the forearm 33 so that the forearm 33 moves above the slide bars 34. At the same time, the forearm 33 is limited by the snap structure 32. A connecting plate 36 is connected to the other end of the forearm 33. A hydraulic rod 37 is provided near the center of the connecting plate 36.
