[0046] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0047] like Figures 1 to 6 As shown, a special-shaped group welding workstation includes:

[0048] A conveying mechanism 100 is used to convey the product 1 to be welded, and the conveying mechanism 100 includes a conveying frame 2;

[0049] A clamping mechanism 200 , wherein the clamping mechanism 200 is connected to the conveying frame 2 and is used to clamp and fix the product 1 on the conveying mechanism 100 ;

[0050] The welding device 300 is located on one side of the conveying mechanism 100 and is used to weld the product 1 clamped and fixed on the conveying mechanism 100 .

[0051] Specifically, after the conveying mechanism 100 conveys the product 1 to its position, the clamping mechanism 200 clamps and fixes the product 1, and then the welding device 300 welds the clamped product 1, thereby preventing the product 1 from shifting during the welding process and thus avoiding the product 1 from being scrapped.

[0052] like Figure 2 As shown, the clamping mechanism 200 may include at least two clamping assemblies 3 sequentially arranged along the conveying direction of the conveying mechanism 100;

[0053] The clamping assembly 3 may include a fixed clamping block 4, a movable clamping block 5, a clamping slide 6 and a clamping cylinder 7;

[0054] The fixed clamping block 4 is connected to the conveying frame 2;

[0055] The clamping slide 6 is slidably connected to the conveying frame 2 along the width direction of the conveying frame 2;

[0056] The movable clamping block 5 is connected to the clamping slide 6, and the conveying mechanism 100 is used to convey the product 1 through between the fixed clamping block 4 and the movable clamping block 5;

[0057] One end of the clamping cylinder 7 is connected to the conveyor frame 2, and the other end of the clamping cylinder 7 is connected to the clamping slide 6. The clamping cylinder 7 is used to drive the clamping slide 6 and the movable clamping block 5 to move toward the fixed clamping block 4 so that the fixed clamping block 4 and the movable clamping block 5 clamp the product 1 on the conveying mechanism 100. Specifically, after the product 1 is transported to the conveying mechanism 100, due to the long length of the product 1, at least two clamping assemblies 3 are required to clamp the product 1 stably and securely, thereby preventing the product 1 from shifting during the welding process. After the product 1 is clamped and secured, the welding device 300 is used to weld the product 1. In this embodiment, the product 1 includes a base plate and ribs spot-welded to the base plate. The welding device 300 is used to fully weld the base plate and the ribs.

[0058] like Figure 1 、 6 As shown, the conveying mechanism 100 may be connected to a positioning mechanism for blocking and positioning the product 1 on the conveying mechanism 100. The positioning mechanism may include a positioning rod 8 and a positioning cylinder 9.

[0059] The positioning rod 8 is connected to the positioning cylinder 9, which is connected to the conveyor frame 2. The positioning cylinder 9 is used to drive the positioning rod 8 to rise so that the positioning rod 8 blocks and positions the product 1. The positioning cylinder 9 is also used to drive the positioning rod 8 to descend to release the blocking positioning of the product 1. Specifically, during operation, the positioning cylinder 9 first drives the positioning rod 8 to rise so that the positioning rod 8 blocks and positions the product 1, then the clamping mechanism 200 clamps and fixes the product 1, and then the welding device 300 welds the product 1; after welding is completed, the clamping mechanism 200 releases the product 1, and then the positioning cylinder 9 drives the positioning rod 8 to descend again to release the blocking positioning of the product 1, and the conveying mechanism 100 continues to convey the product 1.

[0060] like Figures 1 to 6 As shown, the special-shaped small group stand-up welding workstation may further include a ground rail component 10 and a mobile drive mechanism corresponding to the welding device 300;

[0061] The ground rail component 10 is fixedly arranged;

[0062] The welding device 300 is slidably connected to the ground rail component 10 along the conveying direction of the conveying mechanism 100;

[0063] The mobile drive mechanism is connected to the corresponding welding device 300 and is used to drive the corresponding welding device 300 to move on the ground rail component 10. Specifically, because the product 1 is long, it is necessary to drive the welding device 300 to move to different positions on the ground rail component 10 to weld different welding points. In this embodiment, the mobile drive mechanism corresponds to each welding device 300.

[0064] like Figures 1 to 6 As shown, the welding device 300 may include a mobile frame 11 and a welding robot 12;

[0065] The welding robot 12 is connected to the mobile frame 11 and is used to weld the product 1 on the conveying mechanism 100;

[0070] The motor is connected to the corresponding mobile frame 11 so that the motor drives the gear to rotate, and then drives the mobile frame 11 to move on the ground rail component 10 through the cooperation of the gear and the rack, and then drives the welding robot 12 on the mobile frame 11 to move.

[0071] like Figure 1 、 4As shown in Figures 5 and 6, the movable frame 11 is slidably connected to the ground rail component 10 through a linear guide rail, and a lubrication mechanism 13 is connected to the movable frame 11 for conveying lubricating grease to the linear guide rail.

[0074] The lubrication pump is connected to the movable frame 11, the inlet of the lubrication pump is connected to the oil storage container, and the outlet of the lubrication pump is connected to the oil separator. The lubrication pump is used to pump the lubricating grease in the oil storage container into the oil separator and then allow the lubricating grease to flow from the oil outlet of the oil separator to the linear guide rail; wherein, the specific structure of the lubrication pump and the oil separator is the existing technology well known to those skilled in the art and will not be described in detail in this embodiment.

[0078] The controller is connected to the conveying mechanism 100 and the welding robot 12. The controller is used to control the welding robot 12 to weld qualified products 1 according to the scanned image of the product 1. The controller is also used to control the conveying mechanism 100 to convey unqualified products 1 to the repair station according to the scanned image of the product 1. Specifically, if the captured image of the product 1 is significantly different from the original image, it means that there is a problem with the assembly of the product 1, which means that the product 1 is unqualified.

[0079] like Figure 1 、 4 As shown in , 5 and 6, the ground rail component 10 and the conveying mechanism 100 are respectively provided with two;

[0080] The two conveying mechanisms 100 are arranged in parallel between the two ground rail components 10;

[0081] At least one welding device 300 is slidably provided on each of the floor rail components 10;

[0082] The clamping mechanisms 200 are also provided with two and correspond one to one with the conveying mechanisms 100 . The clamping mechanisms 200 are connected to the conveying frames 2 in the corresponding conveying mechanisms 100 and are used to clamp and fix the products 1 on the corresponding conveying mechanisms 100 .

[0083] Specifically, each of the conveying mechanisms 100 is connected to at least one of the positioning mechanisms, and the conveying mechanism 100 can be a roller conveyor. In this embodiment, two of the welding devices 300 are slidably provided on each of the floor rail components 10, and the floor rail component 10 is a robot floor rail.

[0084] To sum up, after the conveying mechanism 100 conveys the product 1 into place, the clamping mechanism 200 clamps and fixes the product 1, and then the welding device 300 welds the clamped product 1, thereby preventing the product 1 from shifting during the welding process and thus avoiding the product 1 from being scrapped.
