In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As shown in the figures Figure 1 , 2 , 3, 4 and 7, the utility model provides a kind of multi-station laser welding machine, including machine table 1, the upper surface of machine table 1 is arranged and distributed with multiple workbenches 2, the inside of workbench 2 is provided with clamp module 3, both sides of workbench 2 are provided with moving mechanism 4, moving mechanism 4 is provided with laser welding head 5 close to clamp module 3 side, to make laser welding head 5 can be moved to the workbench 2 at different positions by moving mechanism 4, one side of machine table 1 is provided with controller 7, controller 7 is electrically connected with clamp module 3, moving mechanism 4 and laser welding head 5.

[0023] When performing welding operations: the metal railing workpieces to be welded can be placed inside the fixture modules 3 on multiple work frames 2 of the machine, and then the moving mechanism 4 is started by the controller 7, so that the moving mechanism 4 can drive the laser welding head 5 to perform welding operations on the joints of the two parts of the metal railings located in the fixture module 3. In this way, the welding machine can continuously weld the metal railing workpieces located at different work stations, and can realize the connection welding of multiple workpieces. At the same time, the moving mechanism 4 and the laser welding head 5 are provided on both sides of the work frame 2, so that the two sides of the metal railing workpiece located at the fixture module 3 can be welded simultaneously, thereby completing the welding operation of the metal railing product. There is no need to re-clamp the workpiece or change the position of the workpiece to perform welding operations on the other side of the product, which can effectively improve the work efficiency during product welding.

[0024] As attached Figure 1 、 2 As shown in Figures 3, 4, 5 and 6, the clamp module 3 includes a first cylinder part 31, a first clamping plate 32 and a second clamping plate 33. The first cylinder part 31 is arranged on one side of the workbench 2, and the movable end of the first cylinder part 31 extends through the workbench 2 and extends into the interior thereof. A movable plate 34 is provided at the movable end of the first cylinder part 31, the first clamping plate 32 is provided on the side of the movable plate 34 away from the first cylinder part 31, and the second clamping plate 33 is provided on the inner side of the workbench 2, with the open end of the second clamping plate 33 facing the open end of the first clamping plate 32. A mold cavity 35 is provided between the first clamping plate 32 and the second clamping plate 33, and a plurality of negative pressure adsorption ports 36 are provided on the side of the first clamping plate 32 and the second clamping plate 33 close to the mold cavity. An air suction device is externally connected to the negative pressure adsorption port 36 so that the negative pressure adsorption port 36 can have an adsorption force.

[0025] When it is necessary to weld and combine two parts of metal railing products: the two parts of the metal railing products can be placed on the open ends of the first clamping plate 32 and the second clamping plate 33 respectively, so that the workpiece to be welded can be first adsorbed through the negative pressure adsorption port 36, thereby preventing the workpiece to be welded from falling out of the first clamping plate 32 and the second clamping plate 33, and then the first cylinder part 31 is started, so that the movable plate 34 can be pushed by the movable end of the first cylinder part 31, and the first clamping plate 32 can be driven to move closer to the second clamping plate 33 by moving the movable plate 34, so that the two parts of the metal railing workpiece can be fitted together, which in turn facilitates the laser welding head 5 to perform welding operations on the connection between the two parts.

[0026] It should be noted that the first clamping plate 32 and the second clamping plate 33 are adjusted according to the internal shape of the workpiece to be welded. At the same time, the two parts of the metal railing products will protrude 3mm~6mm when placed on the first clamping plate 32 and the second clamping plate 33. After the two parts of the metal railing products are fitted to the second clamping plate 33 through the first clamping plate 32, the first clamping plate 32 and the second clamping plate 33 will not be in direct contact, and the two parts of the metal railing products will be fitted side by side. Therefore, a distance of 6mm~10mm will be left between the first clamping plate 32 and the second clamping plate 33, which can facilitate the laser welding head 5 to weld the two parts of the metal railing at the fitting point.

[0027] Preferably, guide rods 37 are provided at the upper and lower ends of the movable plate 34, and the two ends of the guide rods 37 are connected to the inner side surfaces of the work frame 2. A shaft sleeve 38 is provided at the connection between the movable plate 34 and the guide rods 37, so that when the first cylinder 31 drives the movable plate 34 to move toward the second clamping plate 33, it can be guided by the guide rods 37, thereby avoiding the movable plate 34 from deviating.

[0028] As attached Figure 1 、 2 As shown in , 3, 4, 5 and 6, a top pressing module 6 is provided at the upper and lower ends of the working frame 2, and the controller 7 is electrically connected to the top pressing module 6. The top pressing module 6 includes a first top pressing component 61, a second top pressing component 62 and a sliding component 63. The first top pressing component 61 is arranged on one side of the interior of the working frame 2, and the second top pressing component 62 is arranged on the other side of the interior of the working frame 2. The moving end of the first top pressing component 61 is arranged opposite to the second top pressing component 62, and the sliding component 63 is arranged at the top end of the working frame 2, and the movable end of the sliding component 63 is connected to the first top pressing component 61 and the second top pressing component 62.

[0029] When the two parts of the metal railing product are bonded together by the clamp module 3, the first pressing assembly 61 and the second pressing assembly 62 can be activated to move the movable ends of the first pressing assembly 61 and the second pressing assembly 62 to the first clamping plate 32 and the second clamping plate 33 respectively through the sliding assembly 63, so that the workpiece to be welded at the first clamping plate 32 and the second clamping plate 33 can be connected, so that the workpiece to be welded can be positioned on the first clamping plate 32 and the second clamping plate 33, which can effectively avoid the workpiece from being offset during welding;

[0030] After subsequent welding is completed, the clamp module 3 is opened first, so that the welded product can be supported in the work frame 1 through the work of the first pressing component 61 and the second pressing component 62 to prevent it from falling directly to the ground.

[0031] The first pressing assembly 61 includes a second cylinder 611 and a top block 612. The second cylinder 611 is arranged on one side of the work frame 2. The movable end of the second cylinder 611 extends into the work frame 2. The top block 612 is arranged at the movable end of the second cylinder 611. The top surface of the top block 612 is connected to the sliding assembly 63. The bottom end of the top block 612 is provided with a positioning rod 613.

[0032] When a top-joining operation is required, the second cylinder 611 is first activated, and the movable end of the second cylinder 611 drives the top block 612, so that the top block 612 can be moved toward the first clamping plate 32 through the sliding assembly 63. When the top block 612 moves, it can drive the positioning rod 613 to move, so that the positioning rod 613 can top-join the workpiece to be welded at the first clamping plate 32;

[0033] Because the structures of the first pressing assembly 61 and the second pressing assembly 62 are consistent, and are mirrored with the center line of the workbench 2, the working principles of the second pressing assembly 62 are consistent with those of the first pressing assembly 61, so that the second pressing assembly 62 can press the workpiece to be welded at the second clamping plate 33.

[0034] It should be noted that the sliding assembly 63 is a combination of a slide and a slide rail, which is a conventional technical structure on the market.

[0035] As attached Figure 1 、 2 As shown in Figure 7, the moving mechanism 4 includes a first moving component 41, a second moving component 42 and a third moving component 43. The first moving component 41 is arranged on both sides of the workbench 2, the second moving component 42 is arranged at the moving end of the first moving component 41, and the third moving component 43 is arranged at the moving end of the second moving component 42. The moving end of the third moving component 43 is provided with a laser welding head 5.

[0036] By providing a first moving assembly 41, a second moving assembly 42 and a third moving assembly 43, the laser welding head 5 can be driven to move in multiple directions, left and right, front and back, up and down, so as to better meet the welding operation of the workpiece to be welded inside the fixture module 3.

[0037] It should be noted that the first moving assembly 41 , the second moving assembly 42 and the third moving assembly 43 are all assemblies of slides and rails, and are conventional position moving assemblies.

It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
