The fourth hydraulic cylinder 35 can improve the clamping stability of the anode plate and accurately adapt to the edge contour of special-shaped or large-sized anode plates. The linkage system of the air pump 40 and the metal corrugated telescopic tube 41 uses negative pressure adsorption to flexibly fix the surface of the anode plate through the first through hole 38. The fifth hydraulic cylinder 39 is used to adjust the position of the fixing bar 37. Therefore, the clamp improves the clamping efficiency while taking into account the protection function of the brittle metal oxide coating, which significantly improves The welding yield and process reliability can be improved by combining the cooling plate 42 and the serpentine flow channel 43 with the liquid inlet pipe 44, the liquid discharge pipe 45, the coolant tank 46 and the coolant output pump 47 to dynamically manage the welding area and quickly extract the welding heat accumulation to avoid the lattice distortion or peeling of the iridium metal oxide coating due to high temperature, while reducing the risk of thermal deformation of the base titanium material. The visual monitoring component adopts a multi-degree-of-freedom electric pan-tilt 48 equipped with a high-precision CCD camera 49, which can track the welding pool morphology, weld trajectory and inert gas coverage status in real time. Combined with the algorithm analysis of the microcontroller 14, it can automatically correct the welding parameters and optimize the gas flow of the jet ring 26 to ensure process consistency. The synergy of the cooling system and visual feedback not only extends the continuous operation time of the equipment,Precise traceability of welding quality is achieved through data closed-loop control, providing reliable guarantee for mass production of high-performance titanium anode plates.
