Technical Field
[0001] This invention relates to the field of welding equipment technology, and in particular to a multi-station collaborative welding device and method for automotive parts. Background Technology
[0002] Laser welding technology, with its advantages of high energy density, narrow heat-affected zone, minimal welding deformation, and ease of automation, has been widely applied in the component joining processes of the automotive manufacturing industry. As the automotive industry continues to develop towards lightweight and high-strength designs, the welding quality and efficiency of various structural components, brackets, and housing parts directly affect the safety performance and production costs of the entire vehicle. In the mass production of automotive components, how to shorten welding auxiliary time, improve equipment utilization, and achieve continuous and efficient operation has become an important issue of ongoing concern within the industry.
[0003] Currently, most automotive parts welding is performed using single-station laser welding equipment. This type of equipment typically has only one workpiece clamping station. During welding, the operator must first clamp the workpiece to be welded onto the fixture. After the laser welding machine completes the entire welding stroke for the current workpiece, the equipment must be paused or manually intervened to remove the welded workpiece from the fixture before re-clamping the next workpiece to be welded, and only then can the next welding cycle begin. This sequential operation mode of welding, stopping, unloading, loading, and re-welding results in the welding actuator being idle for extended periods during loading and unloading. Auxiliary operation time accounts for a significant portion of the overall production cycle time. This is especially problematic for mass-produced thin-plate and small bracket parts, where the welding time per piece is already short; the frequent equipment start-ups, stops, and clamping operations further amplify the efficiency bottleneck.
[0004] For the reasons mentioned above, existing single-station laser welding equipment has low equipment utilization due to the need to stop and wait for loading and unloading, resulting in low welding efficiency of automotive parts and reduced production efficiency. Summary of the Invention

The laser welding machine 101 then welds the automotive parts. During this process, automotive parts that have already been welded on other fixtures 108 can be removed, and the automotive parts to be welded can be placed back on the empty fixture 108. After the laser welding machine 101 finishes welding the automotive parts, the drive component 104 drives the gear ring 106 and the ring rail 105 to rotate, so that multiple fixtures 108 rotate and adjust their positions.

After the laser welding machine 101 finishes welding the automotive parts, the motor 113 drives the gear 114, the gear ring 106, and the ring rail 105 to rotate, causing the multiple fixtures 108 to rotate and adjust their positions. This enables rapid loading and unloading of automotive parts during the welding process, allowing for multi-station collaborative loading and unloading. This allows the laser welding machine 101 to be quickly put into welding work, reducing downtime and improving the welding efficiency of automotive parts, thereby increasing production efficiency.
[0030] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figures 4-6 ,in, Figure 4 This is a schematic diagram of the overall structure of a second embodiment of a multi-station collaborative automotive parts welding device of the present invention; Figure 5 This is a front sectional view of the second embodiment of a multi-station collaborative automotive parts welding device of the present invention; Figure 6 This is a bottom cross-sectional view of the smoking component of a second embodiment of a multi-station collaborative automotive parts welding apparatus of the present invention.

When the exhaust fan 206 is turned on, the fumes generated during the welding of automotive parts are drawn away by the exhaust fan 206 through the smoke extraction holes 209, the cavity 208, and the duct 207.
[0036] Finally, the plurality of protective nets 210 are respectively fixedly connected to the baffles 204 and are respectively located within the plurality of smoke extraction holes 209. The protective nets 210 can prevent foreign objects from entering the smoke extraction holes 209 and the cavities 208.
[0037] When using this invention, during the welding of automotive parts, the baffle 204 is located on the side of the fixture 108. The baffle 204 is used to block the spatter generated during welding and prevent it from falling onto the gear ring 106. When the exhaust fan 206 is turned on, the fumes generated during the welding of automotive parts are drawn away by the exhaust fan 206 through the exhaust port 209, the cavity 208, and the duct 207. After welding is completed, the hydraulic cylinder 202 is first controlled to drive the bracket 203 and the baffle 204 to move upward, so that the height of the baffle 204 is higher than that of the clamp 108. Then, the motor 113 is started to drive the gear 114, the gear ring 106 and the ring rail 105 to rotate, so that the baffle 204 does not interfere with the clamp 108 when the ring rail 105 drives the clamp 108 to rotate. After the position of the clamp 108 is adjusted, the hydraulic cylinder 202 drives the bracket 203 and the baffle 204 to move downward, so that the baffle 204 returns to the side of the clamp 108.
[0038] Secondly, please refer to Figure 7 , Figure 7 This is a flowchart of a multi-station collaborative welding method for automotive parts according to the present invention.
[0039] This invention also provides a multi-station collaborative welding method for automotive parts, comprising: S1 places the automotive parts to be welded on the empty fixture 108, and drives the gear ring 106 and the ring rail 105 to rotate through the drive component 104, so that the fixture 108 containing the automotive parts moves to the bottom of the laser welding machine 101. The automotive parts to be welded are placed on the empty fixture 108 and fixed. The drive component 104 is controlled to drive the gear ring 106 and the ring rail 105 to rotate, so that the fixture 108 containing the automotive parts moves to the bottom of the laser welding machine 101.
[0040] The S2 laser welding machine 101 performs welding on automotive parts. During this process, automotive parts that have already been welded on other fixtures 108 can be removed, and automotive parts to be welded can be placed on empty fixtures 108, thus achieving rapid loading and unloading of automotive parts during the welding process.
