[0002] MAG welding systems are required in the production and processing of battery boxes for new energy vehicles. MAG (Metal Electrode Gas Shielded Welding) technology is widely used in industries such as automobile manufacturing, construction machinery, and steel structures due to its high welding efficiency, low cost, and wide applicability. With the development of intelligent and automated manufacturing, higher requirements are being placed on the welding precision, production efficiency, and stability of MAG welding systems.
[0003] Traditional MAG welding systems have the following shortcomings in practical applications: First, most adopt a single-robot welding mode, and the loading and unloading of new energy vehicle battery boxes and welding operations cannot be carried out synchronously during the welding process, resulting in low equipment utilization and long production cycles; Second, heat input control relies heavily on preset parameters, making it difficult to adjust in real time according to changes in the material, thickness, and welding environment of new energy vehicle battery boxes, which easily leads to quality problems such as excessively large welding heat-affected zone, deformation of new energy vehicle battery boxes, and weld porosity. Summary of the Invention
[0004] To address the problems in the background art, this utility model proposes a MAG welding system based on dual-robot collaborative control and adaptive heat input optimization.

Placement racks: The placement racks are symmetrically arranged at the edge of the base, and each placement rack has a welding component on its top surface; The top surface of the workbench is equipped with multiple fasteners.
[0006] Preferably, the fixing component includes a U-shaped frame disposed on the top surface of the workbench, a lead screw threadedly connected to the U-shaped frame, and a handle disposed at the end of the lead screw. The other end of the lead screw is rotatably provided with a clamping plate, and the clamping plate is slidably disposed with the U-shaped frame.
[0007] Preferably, the welding assembly includes a welding robot mounted on a placement frame and a welding head disposed at the end of the welding robot.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention utilizes a servo motor to facilitate the rotation of the worktable, thereby allowing the installed new energy vehicle battery box to be rotated under the welding components for easier welding. The use of two welding components further facilitates rapid welding of the new energy vehicle battery box, improving welding efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1-3 This utility model provides a technical solution: The MAG welding system based on dual-robot collaborative control and adaptive heat input optimization includes a base 1 and a worktable 2 set on the top surface of the base 1, with the worktable 2 rotatably mounted to the base 1. A mounting cavity 9 is provided in the middle of the top surface of the base 1, and a servo motor 10 is provided in the mounting cavity 9, with the output shaft of the servo motor 10 fixedly connected to the top surface of the worktable 2. The use of the servo motor 10 facilitates the rotation of the worktable 2, thereby facilitating the rotation of the installed new energy vehicle battery box under the welding assembly for welding purposes. The placement racks 7 are symmetrically arranged at the edge of the base 1, and each placement rack 7 has a welding component on its top surface. The use of two welding components facilitates the rapid welding of the new energy vehicle battery box and improves the welding efficiency of the new energy vehicle battery box. The top surface of the workbench 2 is equipped with multiple fasteners 3; the use of fasteners 3 makes it easy to fix the new energy vehicle battery box, avoids the phenomenon of the new energy vehicle battery box moving during welding, thus facilitating the welding of the new energy vehicle battery box and improving the welding quality of the new energy vehicle battery box.
[0015] In this utility model, the fixing component 3 includes a U-shaped frame 303 set on the top surface of the workbench 2, a lead screw 301 threadedly connected to the U-shaped frame 303, and a handle 304 set at the end of the lead screw 301. The other end of the lead screw 301 is rotatably provided with a clamping plate 302, and the clamping plate 302 is slidably set with the U-shaped frame 303. By rotating the lead screw 301, the clamping plate 302 is moved, and then the clamping force between the clamping plate 302 and the U-shaped frame 303 is used to clamp and fix the new energy vehicle battery box.
[0016] In this invention, the welding assembly includes a welding robot 4 mounted on a mounting frame 7, which is bolted to the top surface of the mounting frame 7. A welding head 5 is located at the end of the welding robot 4 and is bolted to the end of the welding robot 4. A welding machine 6 is also bolted to the top surface of the mounting frame 7, and the welding machine 6 and the welding head 5 are electrically connected by a cable. The welding robot 4 is a Yaskawa welding robot, model AR2010, and the welding machine 6 is a Panasonic welding machine, model GP6. The welding speed can reach 0.85m / min, and precise arc control can be achieved, thereby controlling the welding heat input and ensuring controllable weld quality. The cost is expected to be reduced by 20% compared to the past.
[0017] In this utility model, an annular slider 11 is provided on the bottom surface of the worktable 2, and an annular groove is provided on the top surface of the base 1 to match the annular slider 11; the rotation of the worktable 2 is facilitated by the mutual cooperation of the annular slider 11 and the annular groove.
[0018] In this utility model, a workstation 8 is provided on the front end face of the base 1, and only one workstation 8 is provided, which can reduce the input of one employee and save the welding cost of the new energy vehicle battery box.
[0019] Working principle: When using this utility model, the worker starts placing the new energy vehicle battery box from workstation 8. Specifically, the worker places the new energy vehicle battery box between the U-shaped frame 303 and the clamping plate 302, then rotates the handle 304 to drive the lead screw 301 to rotate, thereby pushing the clamping plate 302 to move. Finally, the clamping force between the clamping plate 302 and the U-shaped frame 303 is used to clamp and fix the new energy vehicle battery box. Then, the servo motor 10 is started, and the output shaft of the servo motor 10 rotates, driving the worktable 2 to rotate, which in turn drives the new energy vehicle battery box to rotate by 90°. Every time the worktable 2 rotates 90°, it moves another new energy vehicle battery box under the welding head 5, and then the worker can continue to place the new energy vehicle battery box on the U-shaped frame 303. At the same time, the welding robot 4 welds the new energy vehicle battery box. After the new energy vehicle battery box is welded, the servo motor 10 continues to rotate, causing the new energy vehicle battery box to rotate and move another unwelded new energy vehicle battery box under the welding head 5. Then, the worker removes the welded new energy vehicle battery box and places another new energy vehicle battery box in the U-shaped frame 303. This allows the new energy vehicle battery box to be installed on one side, rotated to the welding position, and the welding robot 4 to start welding, while the worker on the other side starts picking up and loading parts. This allows the equipment to continue working even when the worker stops, improving the efficiency of the welding work.
