Technical Field

[0001] This utility model relates to the field of battery water-cooled plate welding technology, specifically to a laser welding device for battery water-cooled plates with adjustable angle. Background Technology

[0002] Battery water-cooled plates are key components used in the thermal management of power battery systems. They primarily absorb the heat generated during battery operation through the circulation of liquid, thereby controlling the battery temperature within a reasonable range and ensuring battery performance, lifespan, and safety. Battery water-cooled plates are typically constructed from metal sheets such as aluminum alloys or copper, using processes like stamping, brazing, and friction stir welding to create flow channels and cavities. The surface may be adorned with fins or mesh structures to enhance heat exchange efficiency. Laser welding equipment for battery water-cooled plates is a precision welding device specifically designed for their manufacture. It uses a high-energy-density laser beam focused on the area to be welded on the water-cooled plate, causing the metal material to locally melt and solidify to form a strong weld. This connects key structures such as flow channels and plate splicing. However, existing laser welding equipment cannot rotate the water-cooled plate during use, making welding inconvenient, and it also cannot fix the plate's position, affecting the welding effect.

[0027] 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.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a laser welding device for battery water-cooled plates with adjustable angle, including a base 10, a turntable 20, a placement plate 30, an electric telescopic rod 301, a push plate 302, a pressure sensor 303, a gasket 305, a limiting block 306, a support frame 40, a cylinder 401, a protective cover 402, a robotic arm 403, a welding head 404, and a shock-absorbing column 405;

[0029] The battery water-cooling plate uses a laser welding device, which facilitates the fixing and rotation of the water-cooling plate. The specific implementation method is as follows:

[0030] A turntable 20 is embedded in the surface of the base 10, and a placement plate 30 is connected to the surface of the turntable 20. A movable structure is installed on the surface of the base 10, and the movable mechanism includes: an electric telescopic rod 301 symmetrically mounted on the surface of the turntable 20, a push plate 302 connected to the end of the output shaft of the electric telescopic rod 301, a pressure sensor 303 mounted on the surface of the push plate 302, and gaskets 305 symmetrically mounted on the surface of the push plate 302. A limit block 306 is connected to the surface of the gaskets 305. The turntable 20 and the base... The base 10 and the placement plate 30 are rotatably connected. The surface of the placement plate 30 is provided with a groove, and the bottom of the push plate 302 is inserted into the groove on the surface of the placement plate 30. The placement plate 30 and the push plate 302 are slidably connected. The end of the push plate 302 is correspondingly set with the surface of the pressure sensor 303. The placement plate 30 and the push plate 302 are slidably connected. The protective cover 402 is positioned correspondingly to the placement plate 30, and the protective cover 402 is set on the outside of the placement plate 30.

[0031] The water-cooled plate is placed on the surface of the placement plate 30. At this time, the electric telescopic rods 301 on both sides are activated, causing their ends to extend. The ends of the electric telescopic rods 301 push the push plate 302, causing its bottom to move within the groove on the surface of the placement plate 30. Simultaneously, the push plates 302 on both sides slide on the surface of the placement plate 30, causing the push plates 302 to move the pad 305 inward. The pad 305 then moves the limiting block 306 inward. When the limiting block 306 moves, the water-cooled plate exerts resistance on the limiting block 306, causing the limiting block 306 to move inward. 6. End-compression pressure sensor 303. When pressure sensor 303 receives compression, it measures the pressure formed on the water-cooled plate. At the same time, pressure sensor 303 transmits an electrical signal to the control system. The control system closes the electric telescopic rod 301, so that the electric telescopic rod 301 fixes the position of the limit block 306, fixing the water-cooled plate on the surface of the placement plate 30. At this time, the placement plate 30 is rotated by hand, so that the placement plate 30 drives the turntable 20 to rotate, so that the turntable 20 rotates on the surface of the base 10. At this time, the placement plate 30 drives the water-cooled plate on the surface to rotate, thus adjusting the position of the water-cooled plate.

[0032] The battery water-cooling plate uses a laser welding device, which facilitates protection during welding. The specific implementation method is as follows:

[0033] A support frame 40 is mounted on the surface of the base 10, and a cylinder 401 is mounted on the surface of the support frame 40. A protective cover 402 is connected to the end of the output shaft of the cylinder 401. A robotic arm 403 is connected to the end of the output shaft of the protective cover 402, and a welding head 404 is connected to the end of the robotic arm 403. A shock-absorbing column 405 is connected to the surface of the base 10. The protective cover 402 is positioned corresponding to the placement plate 30, and the protective cover 402 is located on the outside of the placement plate 30. The end of the shock-absorbing column 405 is positioned corresponding to the protective cover 402, and the protective cover 402 is made of transparent material.

[0034] The end of cylinder 401 drives the protective cover 402 to move downward, so that the protective cover 402 moves to the outside of the placement plate 30 and wraps the placement plate 30 inside the protective cover 402. At the same time, the protective cover 402 drives the robotic arm 403 to move, and the robotic arm 403 drives the welding head 404 to move downward. When the bottom of the protective cover 402 is in contact with the surface of the shock absorber 405, cylinder 401 is closed to fix the position of the protective cover 402. At this time, the control system drives the robotic arm 403 to move, so that the robotic arm 403 welds the water-cooled plate. At this time, the protective cover 402 can block the outside of the water-cooled plate to prevent sparks from flying out.

[0035] Working principle: When using this adjustable-angle laser welding device for battery water-cooled plates, a push plate 302, a pressure sensor 303, a gasket 305, and a limit block 306 are provided to facilitate the fixing and rotation of the water-cooled plate. A cylinder 401, a protective cover 402, and a shock-absorbing column 405 are provided to facilitate protection during welding, thereby increasing the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
