Description

Technical Field

[0001] The utility model relates to the technical field of visual recognition devices, in particular to a visual recognition device for pole-changing operations in an electrolysis workshop. Background Art

[0002] The anode changing device in the electrolysis workshop is a device used to automatically grasp and replace anodes during the electrolysis production process. It is generally composed of a robotic arm, a gripper, a drive mechanism and a control system.

[0003] The robotic arm can move in three dimensions, precisely positioning its gripper to the desired anode. The gripper typically has adjustable gripping force, allowing it to securely grasp the anode according to its size and shape through mechanical structures (such as clamps and claws). A drive mechanism, typically hydraulic, pneumatic, or electric, powers the movement of the robotic arm and gripper. A control system receives commands and precisely controls the movements of the robotic arm and gripper, ensuring accurate anode handling, handling, and placement.

[0004] During the pole changing process, the position of the gripper and the anode is generally determined by a visual sensor installed on one side of the gripper. However, in the actual pole changing process, the electrolysis workshop is an environment with a strong magnetic field, high temperature and high dust. Therefore, the lens surface of the visual sensor is often affected by the adhesion of dust and strong magnetic effects, which affects the normal operation. Therefore, the visual sensor needs to be inspected and cleaned frequently. However, the visual sensor in the prior art is generally fixed by bolts. During the inspection and cleaning process, multiple bolts need to be rotated in sequence to realize the installation and disassembly of the visual sensor, which affects the inspection and cleaning efficiency of the visual sensor.
