[0019] Example This embodiment provides a lead-acid battery welding device, such as... Figures 1-4As shown, it includes: a base 100, a motor-driven conveyor belt 114 on the surface of the base 100, a bracket 110 fixedly connected to the top of the base 100, an electric push rod 111 slidably connected to the bracket 110, a mounting plate 112 fixedly connected to the telescopic end of the electric push rod 111, a battery tab welding head 113 fixedly connected to the bottom of the mounting plate 112, and a fumigation mechanism 200 for absorbing welding fumes on the base 100; the fumigation mechanism 200 includes a filter box 213 fixedly installed at the bottom of the base 100, a fan 214 fixedly installed on one side of the filter box 213, a pressure plate 210 below the mounting plate 112, an air inlet 211 at the bottom of the pressure plate 210, and the air inlet 211 and the filter box 213 are connected by an air duct 212.

[0020] A lead-acid battery welding device employing the above technical solution is equipped with a fume extraction mechanism 200. When welding the battery, the fan 214 is started, creating a negative pressure inside the filter box 213. At this time, the welding fumes are drawn in from the air inlet 211 and sent into the filter box 213 through the air duct 212. After being filtered by the filter plate inside the filter box 213, the fumes are discharged, thus treating the harmful gases and reducing harm to the human body. When welding the battery, the electric push rod 111 extends, and the mounting plate 112 drives the pressure plate 210 to move down, pressing and fixing the battery through the pressure plate 210 to ensure stability during welding.

[0021] To treat harmful gases, the filter box 213 has internal slots for holding coarse filter plates, fine filter plates, and activated carbon adsorption plates. The coarse and fine filter plates filter dust from the air, while the activated carbon adsorption plates adsorb harmful substances from the air, thus treating welding fumes.

[0022] For replacing the filter plates and adsorption plates, a maintenance cover is rotatably connected to one side of the filter box 213. A sealing ring is provided at the junction of the maintenance cover and the side wall of the filter box 213. The sealing ring improves the airtightness of the filter box 213, preventing air leakage and the release of untreated gas.

[0023] To compress the battery and improve stability during welding, a telescopic mechanism 220 connects the pressure plate 210 and the mounting plate 112. The telescopic mechanism 220 includes a fixed rod fixedly connected to the top of the mounting plate 112, a telescopic rod slidably connected to the bottom of the fixed rod, and the telescopic rod fixedly connected to the top of the pressure plate 210. A spring is fixedly connected between the pressure plate 210 and the mounting plate 112. An electric push rod 111 moves the mounting plate 112 downwards, causing the pressure plate 210 to first contact the battery. The electric push rod 111 then moves the battery tab welding head 113 further downwards, causing the pressure plate 210 to compress the spring and perform a tight welding of the battery.

[0024] To prevent the pipes from affecting the lifting and lowering of the pressure plate 210, a through hole corresponding to the battery tab welding head 113 is opened at the center of the surface of the pressure plate 210, and the air duct 212 is set as a telescopic pipe.

[0025] To prevent the pipes from becoming blocked, reinforcing rings are spaced apart on the inner wall of the expansion joint, and these reinforcing rings are perpendicular to the axis of duct 212. Even when the pipes contract, airflow can still be maintained.

[0026] To ensure stability when pressing the battery, four telescopic mechanisms 220 are provided and symmetrically arranged between the pressure plate 210 and the mounting plate 112.

[0027] In summary, the lead-acid battery welding device provided in this embodiment has the following advantages: A fume extraction mechanism 200 is provided. When welding the battery, the fan 214 is started, creating a negative pressure inside the filter box 213. At this time, the welding fumes are drawn in from the air inlet 211, sent into the filter box 213 through the air duct 212, filtered by the filter plate inside the filter box 213, and then discharged, treating harmful gases and reducing harm to the human body. When welding the battery, the electric push rod 111 extends, and the mounting plate 112 drives the pressure plate 210 to move downwards, pressing and fixing the battery through the pressure plate 210, ensuring stability during welding.

[0028] During use, the battery pack is moved to the area below the battery tab welding head 113 via the conveyor belt 114. The battery tab welding head 113 is lowered by the electric push rod 111 to weld the battery. The welding fumes generated during welding are drawn into the filter box 213 for purification and then discharged under the action of the fan 214, thus avoiding harm to the human body from the welding fumes.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
