Battery module aluminum bar welding is the process of connecting the aluminum bar to the battery module through welding technology.

After the two pairs of aluminum bar bodies 4 are fixed, the first electric telescopic rod 8 drives the welding head of the laser welder 7 to approach the aluminum bar body 4. At the same time, the sliding rod cylinder 5 drives the first electric telescopic rod 8 and the laser welder 7 to move, and a pair of aluminum bar bodies 4 on one side are welded, and the laser welder 7 welds the aluminum bar bodies 4 on the other side. During the process, smoke is generated. At this time, the exhaust fan 1301 draws the smoke into the second telescopic hose 1306 through the bend 1305 on the other side, and then introduces it into the connecting pipe 1303 through the bend 1305 on one side and the first telescopic hose 1304, and then enters the purification box 14 through the air guide pipe 1302. The harmful gas therein is purified by the purification liquid, and then the large amount of fine particles and odors therein are adsorbed and filtered by the detachable activated carbon plate 13011 to be discharged cleanly. After the welding of a pair of aluminum row bodies 4 on one side is completed, the second electric telescopic rod 1104 pulls the rack plate 1103 and the movable sleeve plate 1102 to move along the T-shaped rod 1106, so that the rack plate 1103 drives the gear 1101 through the meshing action. It rotates 180°, driving the mounting plate 2 and the battery module body 3 to rotate, so that the unwelded aluminum row body 4 on the other side rotates to the bottom of the laser welder 7, and the gear 1101 rotates to drive the rotating rod 1308 and multiple stirring blades 1309 to rotate, stirring the purified liquid to flow, fully contacting with the smoke, and fully removing the harmful gases therein, and during the movement of the movable sleeve plate 1102, it drives the extrusion hemisphere 1201 to move synchronously, and during the movement of the extrusion hemisphere 1201, it contacts with multiple active protrusions 1205 in turn, and squeezes the active protrusions 1205 to move when in contact, driving the double-hole sleeve plate 1206 to move along a pair of I-shaped rods 1208, so that the insulation sealing plate 1207 is separated from the insulation frame 1202, and the insulation is cancelled.The cold air generated by the cooling of the magnetic refrigeration rod 1204 overflows and flows around the mounting plate 2, cooling the laser welder 7 that has just finished working, and then the laser welder 7 continues to weld the battery module body 3 and the aluminum bar body 4 on the other side.
