Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion-proof fields. The robotic arm is a complex system with uncertainties such as parameter perturbations, external interference, and unmodeled dynamics. Therefore, the modeling model of the robotic arm also has uncertainties. For different tasks, it is necessary to plan the motion trajectory of the robotic arm joint space, so as to cascade and form the terminal posture.

Among them, the utility model provides a welding robot arm operation device, which solves the problem that the existing welding robot arm is easy to leak welding.

[0004] In the above-mentioned prior art solution, an image acquirer is provided, and the target part after welding is photographed and detected by the image acquirer. The image acquirer transmits the captured image signal to the processor, and then the processor controls the second robot arm to perform repair welding on the target part according to the received image signal. However, the second robot arm is equipped with an image acquirer and a welding device, so that when the second robot arm performs the repair welding operation, the smoke generated during welding flows upward and easily adheres to the camera end of the image acquirer, resulting in the image acquired by the image acquirer not being clear enough.

[0010] In some embodiments, a guide plate is fixedly mounted on the bottom end of the connecting pipe, and the guide plate is in the shape of a hollow frustum.

[0011] In some embodiments, moving seats are slidably mounted on both sides of the sliding track, and the two mechanical arms are respectively fixedly mounted on a side wall far from the two moving seats.

[0012] Compared with the prior art, the utility model has the following significant advantages:

[0013] Firstly, the utility model uses a camera to shoot the welding place of the welding device, so that the staff can check the welding results in real time. During the welding process, the fan generates suction inside the connecting pipe to suck away the smoke generated during welding, so as to avoid the smoke during welding adhering to the camera end of the camera, which causes the camera to be unable to shoot well.
