[0015] The first clamp block and the second clamp block are slidably connected to the fixed rod, and the first clamp block and the second clamp block are threadedly connected to the lead screw.

[0016] In some embodiments, the first clamping assembly further includes a drive mechanism;

[0017] The drive mechanism is connected to the lead screw drive. The drive mechanism is configured to drive the lead screw to rotate, and the lead screw drives the first clamp block and the second clamp block to move closer to each other or further away from each other.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0036] Firstly, such as Figure 1 As shown, an embodiment of this application provides a laser welding station 100, including a fixed plate 1 and a first clamp assembly 2. A plurality of first telescopic rods 11 are provided on one side of the fixed plate 1, and the first telescopic rods 11 are adapted to extend and retract along a first direction X. The first clamp assembly 2 and the fixed plate 1 are arranged opposite to each other along the first direction X, and the clamp assembly is connected to the fixed plate 1 through the plurality of first telescopic rods 11.

[0037] The first clamping assembly 2 can clamp the workpiece to be welded. Multiple first telescopic rods 11 can adjust the distance between the first clamping assembly 2 and the fixed plate 1, and also adjust the angle. For example, when two first telescopic rods 11 are included, if one first telescopic rod 11 is extended while the other is compressed, the first clamping assembly 2 can be tilted relative to the fixed plate 1, thereby adjusting the angle between the first clamping assembly 2 and the fixed plate 1, and thus adjusting the angle of the workpiece to be welded. That is, the laser welding station 100 provided in this embodiment, through the cooperation of multiple first telescopic rods 11, can adjust the position and angle of the first clamping assembly 2, improving the degree of adjustment freedom and meeting the needs of different welding scenarios.

[0038] Among them, such as Figure 1As shown, the first telescopic rod 11 can be a double-section support rod, with a ball joint at one end near the first clamp assembly 2. The first clamp assembly 2 is provided with a corresponding bushing. The first clamp assembly 2 is connected to the first telescopic rod 11 through the bushing and the ball joint, which, while realizing telescopic adjustment, also helps to realize angle adjustment by utilizing the cooperation of the ball joint and the bushing, thereby improving the flexibility of adjustment.

[0039] It is understood that the selection of the first telescopic rod 11 and the connection form between the first telescopic rod 11 and the first clamp assembly 2 are merely illustrative examples, and those skilled in the art may choose other forms as needed.

[0040] In some embodiments, such as Figure 2 As shown, the laser welding station 100 also includes a first connector 3 and a second connector 4. The first connector 3 is connected to the fixed plate 1, and the second connector 4 is movably connected to the first clamp assembly 2. The first connector 3 and the second connector 4 are adapted to slide together along a first direction X.

[0041] The connection stability between the first clamp assembly 2 and the fixed plate 1 can be improved by using the first connector 3 and the second connector 4. Through the cooperation between the first connector 3, the second connector 4 and the multiple first telescopic rods 11, telescopic movement can be achieved, the angle can be adjusted, and the stability of the first clamp assembly 2 during the welding process can be ensured.

[0042] Specifically, the first connecting member 3 is disposed at the bottom of the fixed plate 1, and the second connecting member 4 is disposed at the bottom of the first clamping assembly 2. The first connecting member 3 is fixedly connected to the fixed plate 1 to ensure structural stability. The second connecting member 4 is movably connected to the first clamping assembly 2. While achieving a sliding connection through the first connecting member 3 and the second connecting member 4, it also ensures the degree of freedom of the first clamping assembly 2 relative to the fixed plate 1, making it convenient to adjust the angle of the first clamping assembly 2.

[0043] For example, such as Figure 2 As shown, the first clamp assembly 2 and the second connecting plate can be connected by a rotating shaft 42. The first clamp assembly 2 can rotate around the rotating shaft 42, thereby placing the multiple first telescopic rods 11 in different states and thus achieving angle adjustment. The first connecting member 3 can be provided with a sliding groove 31 extending along the first direction X, and the second connecting member 4 can be provided with a slider 41. Through the cooperation of the sliding groove 31 and the slider 41, the first connecting member 3 and the second connecting member 4 can slide along the first direction X.

[0044] In some embodiments, such as Figure 1 As shown, the laser welding station 100 includes four first telescopic rods 11, which are arranged in a ring.

[0045] By setting four first telescopic rods 11 and arranging them in a ring, the connection stability between the first clamping assembly 2 and the fixed plate 1 can be ensured while giving the first clamping assembly 2 good freedom. By placing the four first telescopic rods 11 in different extension and retraction states, the angle of the first clamping assembly 2 relative to the fixed plate 1 can be adjusted, thereby realizing the adjustment of the laser welding angle.

[0046] It is understood that the number of four first telescopic rods 11 is only for illustrative purposes. Depending on actual needs, two, six or eight first telescopic rods 11 can also be selected, as long as the first clamp assembly 2 and the fixed plate 1 can be telescopically connected and the angle can be adjusted.

[0047] In some embodiments, such as Figure 3 As shown, the first clamp assembly 2 includes a first clamp base 21 and a first clamp body 22. The first clamp base 21 is connected to the fixed plate 1 through a plurality of first telescopic rods 11, and the first clamp body 22 is disposed on the side of the first clamp base 21 opposite to the fixed plate 1.

[0048] The first clamping base 21 is used to connect the first clamping assembly 2 and the fixing plate 1, and to ensure the degree of freedom of the first clamping assembly 2. The first clamping body 22 is used to clamp the workpiece to be welded. By adjusting the relative position between the first clamping base 21 and the fixing plate 1, the first clamping body 22 can be moved, thereby adjusting the position and angle of the workpiece to be welded.

[0049] In some embodiments, such as Figure 3 As shown, the first clamp base 21 is provided with a fixing rod 211 and a lead screw 212, both extending along a second direction Y, which intersects with the first direction X. The first clamp body 22 includes a first clamp block 221 and a second clamp block 222 disposed opposite to each other along the second direction Y. The first clamp block 221 and the second clamp block 222 are slidably connected to the fixing rod 211, and are threadedly connected to the lead screw 212.

[0050] The moving direction of the first clamping block 221 and the second clamping block 222 can be restricted by the fixing rod 211. The screw 212 is threadedly connected to the first clamping block 221 and the second clamping block 222, and the relative position between the first clamping block 221 and the second clamping block 222 can be adjusted by rotating the screw 212, thereby realizing the clamping and disassembly of the workpiece to be welded.

[0051] For example, such as Figure 3As shown, two fixing rods 211 may be included to improve the stability of the first clamping block 221 and the second clamping block 222 during the sliding process along the second direction Y. The two fixing rods 211 may be disposed on opposite sides of the lead screw 212.

[0052] In some embodiments, such as Figure 3 As shown, the first clamping assembly 2 also includes a drive mechanism 23. The drive mechanism 23 is drivenly connected to the lead screw 212, and the drive mechanism 23 is configured to drive the lead screw 212 to rotate, and the lead screw 212 drives the first clamping block 221 and the second clamping block 222 to move closer to or further away from each other.

[0053] The first clamp block 221 and the second clamp block 222 can be adjusted by the drive mechanism 23, thereby improving the degree of automation and adjustment efficiency.

[0054] For example, the drive mechanism 23 can be a drive motor. When the drive motor is working, it can drive the lead screw 212 to rotate, thereby driving the first clamping block 221 and the second clamping block 222 to move along the second direction Y, changing the distance between the first clamping block 221 and the second clamping block 222. The lead screw 212 may include two symmetrically arranged threaded sections in the second direction Y, and the two threaded sections are arranged in opposite directions. When the lead screw 212 rotates, it can cause the first clamping block 221 and the second clamping block 222 to move towards each other or away from each other, thereby bringing the first clamping block 221 and the second clamping block 222 closer together or further apart.

[0055] In some embodiments, such as Figure 3 As shown, anti-slip pads 2211 are provided on both the first clamp block 221 and the second clamp block 222.

[0056] By using the anti-slip pad 2211 provided on the second clamping block 222 and the first clamping block 221, the clamping stability of the first clamping assembly 2 on the workpiece to be welded can be improved.

[0057] In some embodiments, such as Figure 4 As shown, the laser welding station 100 also includes a second clamping assembly 5 and a plurality of second telescopic rods 12. The plurality of second telescopic rods 12 are disposed on the side of the fixing plate 1 opposite to the first telescopic rod 11, and the plurality of second telescopic rods 12 extend along a first direction X. The second clamping assembly 5 is connected to the fixing plate 1 through the plurality of second telescopic rods 12.

[0058] Specifically, a first clamping assembly 2 and a second clamping assembly 5 are respectively provided on both sides of the fixed plate 1 along the first direction X. The first clamping assembly 2 is connected to the fixed plate 1 via multiple first telescopic rods 11, and the second clamping assembly 5 is connected to the fixed plate 1 via multiple second telescopic rods 12. This configuration allows for two welding positions to be included simultaneously within a single laser welding station 100, enabling the simultaneous welding of two workpieces and improving integration.

[0059] It is understandable that the second clamping assembly 5 can have the same structure as the first clamping assembly 2, or it can differ from it. When the second clamping assembly 5 and the first clamping assembly 2 have the same structure, design and manufacturing costs can be reduced and maintenance efficiency improved. When the structures of the second clamping assembly 5 and the first clamping assembly 2 differ, different welding scenario requirements can be met by using the second clamping assembly 5 and the first clamping assembly 2.

[0060] Secondly, embodiments of this application also provide a laser welding system, such as... Figure 5 As shown, it includes the laser welding station 100 as described above.

[0061] The laser welding system provided in this application embodiment has all the beneficial effects of the laser welding station 100 described above, which will not be repeated here.

[0062] In some embodiments, such as Figure 5 As shown, the laser welding system includes a worktable 210 and multiple laser welding stations 100. The laser welding stations 100 are disposed on the worktable 210, and partitions 220 are provided between adjacent laser welding stations 100.

[0063] By including multiple laser welding stations 100 in a single laser welding system, the integration level can be further improved, enabling simultaneous welding of multiple tasks to meet the needs of more application scenarios.

[0064] For example, such as Figure 5 As shown, the laser welding system includes two laser welding stations 100, both of which are set on the worktable 210 and are separated by a partition 220, so that the same laser welding system includes multiple welding stations.

[0065] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
