Description

Technical Field

[0001] This utility model relates to the field of laser welding of seat handles, specifically a dual-station laser welding device for seat handles. Background Technology

[0002] In the field of seat manufacturing, the welding quality of seat handles directly affects the overall structural strength and safety of the seat. Laser welding has become a common process for welding seat handles due to its advantages such as high welding precision and small heat-affected zone, and corresponding laser welding equipment has also been widely used. Currently, most laser welding devices for seat handles on the market are single-station designs, meaning they can only weld one seat handle at a time. During the welding process, the seat handle must first be fixed by a clamping device. After welding is completed, the clamping device is released to remove the workpiece, and then a new workpiece to be welded is re-clamped. The welding mechanism has a long idle waiting time throughout the process, which is difficult to meet the needs of efficient production. At the same time, the clamping and fixing of existing devices mostly rely on manual operation, requiring manual adjustment of the clamping position and locking. This is not only cumbersome, but also prone to errors due to human operation, resulting in the seat handle not being firmly fixed or misaligned, which affects the welding accuracy and may even lead to welding misalignment, incomplete welding, and other problems, increasing subsequent rework costs. Therefore, a dual-station laser welding device for seat handles needs to be designed to solve the above problems. Utility Model Content

At the bottom of the first slider 3 and at the top of the linkage frame 1, there is an opening 20 for use with the first slider 3. By setting a drive mechanism and placing the handle to be welded inside the L-shaped frame 15, the first motor 8 is started. The first motor 8 drives the turntable 9 to rotate. The rotation of the turntable 9 drives the slide rod 10 to move. The movement of the slide rod 10 drives the strip frame 13 to move back and forth. The movement of the strip frame 13 drives the first slider 3 to move. The movement of the first slider 3 can drive the second slide plate 4 to move.
