Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding tooling for a square battery cell module. Background Technique

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is an important aspect of the application of laser material processing technology, mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] The existing welding tooling designs generally tend to be fixed in position. Since the position of the welding tooling is immovable, workers have to spend a lot of time and energy to accurately move the workpiece to be welded to the preset welding station. This process not only greatly increases the cost of material handling but also significantly increases the complexity of the operation process. In addition, the fixed welding tooling limits the operation flexibility to a certain extent. During the welding process, fine-tuning or quickly switching the welding points may be required according to the actual situation, but the fixed tooling position often fails to meet these requirements. This limitation may make the welding operation more cumbersome and difficult, and may even affect the final welding quality and overall efficiency due to the inability to adapt to changes.

[0037] Working principle: The user places the battery cell module body 73 on the top of the flow plate 71, making it located on one side opposite to the two limiting blocks 76. Subsequently, the aluminum palladium 74 is placed on the surface of the aluminum palladium 74. The limiting plate 75 can limit the aluminum palladium 74. Then, the user starts the lifting cylinder 64, and the output end of the lifting cylinder 64 drives the round block 63 to move upward. The round block 63 drives the first fixing plate 62 to move.

Then, by starting the transmission mechanism 4, the transmission mechanism 4 drives the clamping block 5 to move. The clamping block 5 drives the flow plate 71 to move. When the flow plate 71 moves, it will drive the lifting mechanism 6 to move and simultaneously drive the battery cell module body 73 to move. When the battery cell module body 73 moves to a specified position, the user starts the electric guide rail 82, so that the slider 83 slides on the surface of the electric guide rail 82. The slider 83 drives the second fixing plate 84 to move. Then, the second fixing plate 84 is started. The second fixing plate 84 can drive the second placement plate 91 to move. The second placement plate 91 drives the air knife 92 to move. The second placement plate 91 drives the third placement plate 93 to move through the pressing cylinder 95. The third placement plate 93 drives the fireproof bellows 94 to move. When the third placement plate 93 moves, it drives the suction pipe 98 to move, thereby increasing the dust collection range.
