Description

Technical Field

[0001] The utility model relates to the technical field of guiding mechanisms, in particular to a twisting and pulling guiding device for an automatic anode grabbing device for pole changing in an electrolysis workshop. Background Technique

[0002] The automatic anode grabbing device for pole changing in an electrolysis workshop is a device used in the electrolysis production process to achieve automatic grabbing and replacement of anodes. It generally consists of a robotic arm, a gripper, a driving mechanism, a control system, etc. The robotic arm can move in three-dimensional space to accurately position the gripper at the anode position to be grabbed. The gripper usually has adjustable clamping force and can tightly grasp the anode according to the size and shape of the anode through mechanical structures (such as clamps, jaws, etc.). The driving mechanism provides power for the movement of the robotic arm and the gripper, and common methods include hydraulic drive, pneumatic drive, and electric drive. The control system is responsible for receiving instructions and precisely controlling the actions of the robotic arm and the gripper to ensure that operations such as grabbing, transporting, and placing the anode are accurate.

[0003] Since a connecting component is provided between the anode and the electrolysis furnace for fixation, a twisting and pulling device is installed on the gripper to disassemble the fixing piece. However, during the twisting and pulling operation, the twisting and pulling device needs to accurately align with and act on the anode guide rod and its connecting components (such as bolts of the small box fixture, etc.). During the movement of the gripper, due to the long distance between the gripper and the connecting component, the twisting and pulling device is prone to misalignment with the connecting component during movement, thus affecting the use effect of the twisting and pulling device.
