Description

Technical Field

[0001] This utility model relates to the field of sodium batteries, and more specifically, to a sodium battery top cover welding device. Background Technology

[0002] Sodium batteries, also known as sodium salt batteries, are safer and more stable than aluminum batteries. They also have a longer lifespan, simpler recycling processes, and less pollution. They are widely used in various household appliances and electric toys and are an environmentally friendly energy storage device.

[0003] A search revealed an existing patent (publication number: CN221560125U) that discloses a battery top cover sealing welding device. The welding device includes a clamp, a laser welding head, an output optical fiber, and a laser. The clamp is used to fix the battery casing and top cover. The clamp includes a bottom rotating platform, a fixed base, multiple cylinders, and a top rotating platform. The fixed base is fixed to the bottom rotating platform, and the multiple cylinders are fixed to the fixed base and the top rotating platform, used to push the casing tight and press down to fix the top cover. The bottom and top rotating platforms can rotate coaxially and synchronously. The laser light generated by the laser is transmitted to the laser welding head via the output optical fiber, and the laser welding head outputs laser light to weld the top cover and casing. The welding device provided by this invention can ensure faster welding speed, better weld formation, and better welding quality, while eliminating the need for pre-tack welding.

[0004] The slight deformation that may occur during the processing of existing sodium batteries makes it difficult to achieve precise fitting and positioning. When pressing and fixing the top cover, excessive pressure can easily cause deformation or surface damage to the top cover, reducing the product qualification rate. At the same time, the patent documents cited above do not propose any solutions to solve the above problems.

[0005] Therefore, a sodium battery top cover welding device is proposed to address the above problems. Utility Model Content

[0020] 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.

[0021] Example 1

[0022] As attached Figures 1 to 4 The sodium battery top cover welding device shown includes a workbench 1. A drive motor 10 is provided on one side of the upper end of the workbench 1. The drive motor 10 is connected to a lead screw 11 through an output shaft. A sliding block 12 is threaded to the outside of the lead screw 11. A connecting seat 13 is provided at equal intervals on the upper end of the sliding block 12. A cylinder 14 is provided on the upper end of one side of the connecting seat 13. A buffer mechanism 16 is connected to one side of the cylinder 14 through a pneumatic rod 15. A flexible pressure head 17 is provided at the bottom of the buffer mechanism 16.

[0023] Among them, the pressing component with a flexible pressing head 17 that directly contacts the top cover of the sodium battery is made of flexible material. On the one hand, it enhances the fit with the surface of the top cover and avoids scratches on the appearance of the top cover due to hard contact. On the other hand, it can adapt to the slight unevenness of the surface of the top cover through its own slight deformation, ensuring the pressing stability and ensuring that the top cover and the shell fit tightly.

[0024] Example 2

[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the upper end of the workbench 1 is provided with placement slots 2 at equal intervals, and the placement slots 2 are fitted with elastic slots 3; furthermore, by providing placement slots 2 at equal intervals on the upper end of the workbench 1, the horizontal displacement of the shell can be precisely limited, ensuring that the shell is placed in a uniform position.

[0027] In a preferred embodiment, a rotary motor 18 is connected to the bottom fixed frame of the workbench 1. A drive wheel 19 is connected to one side of the rotary motor 18 via an output shaft. A belt 20 is sleeved on the outside of the drive wheel 19, and driven wheels 21 are evenly spaced on one side of the drive wheel 19. Furthermore, by providing a rotary motor 18, the drive wheel 19 is driven to rotate via the output shaft, providing rotational power for the annular weld seam during sodium battery welding.

[0028] In a preferred embodiment, the driven wheel 21 is sleeved with the belt 20, and the upper ends of the driving wheel 19 and the driven wheel 21 are connected to the elastic groove 3 through the fixed seat; furthermore, by providing the elastic groove 3, it has a certain elastic deformation capability, and can conform to the outer wall of the shell by its own deformation when the shell undergoes slight deformation due to processing error.

[0029] In a preferred embodiment, a hydraulic cylinder 4 is provided on the other side of the upper end of the workbench 1, a hydraulic rod 5 is sleeved on one side of the hydraulic cylinder 4, and a slider 6 is fixedly provided on one side of the hydraulic rod 5; furthermore, by providing the hydraulic cylinder 4, the hydraulic rod 5 is driven to extend and retract, providing power for the lateral movement of the slider 6, ensuring that the welding head 9 can be aligned with the seam of batteries of different specifications.

[0030] In a preferred embodiment, an electric telescopic rod 7 is fixedly provided on the upper end of the slider 6, and a connecting rod 8 is fixedly provided on the upper end of each electric telescopic rod 7. Welding heads 9 are provided at equal intervals on the side of the connecting rod 8 near the placement groove 2. Furthermore, by providing the electric telescopic rod 7, the height of the connecting rod 8 can be changed, thereby adjusting the vertical distance between the welding head 9 and the sodium battery joint, ensuring that the welding head 9 can accurately fit the welding position.

[0031] The working process of this utility model is as follows:

[0032] After the drive motor 10 starts, it drives the lead screw 11 to rotate through the output shaft. Since the lead screw 11 and the sliding block 12 are connected by a thread, the rotational motion of the lead screw 11 is converted into the linear motion of the sliding block 12 along the axis of the lead screw 11. The connecting seats 13, which are evenly spaced on the upper end of the sliding block 12, move synchronously with the sliding block 12, thereby driving the cylinder 14, the buffer mechanism 16, and the flexible pressure head 17 to adjust their positions as a whole. This allows for precise adaptation to the positioning reference of the top cover according to the size requirements of sodium batteries of different specifications, ensuring that the relative position of the pressing component and the sodium battery meets the welding requirements. At the same time, the placement groove 2 at the upper end of the worktable 1 is used to accommodate the sodium battery shell. The elastic groove 3 inside the placement groove 2 can adapt to the slight processing error of the shell through its own elastic deformation, further improving the fitting and positioning accuracy of the shell and the top cover. The pressing and fixing of the top cover is achieved through a combination structure of cylinder 14 driving and buffer protection. When the sodium battery shell and the top cover are placed in place, the cylinder 14 is activated, and the buffer mechanism 16 and the flexible pressure head 17 are pushed towards the top cover through the air rod 15. The buffer mechanism 16 can absorb the impact force during the pressing process, avoiding deformation of the top cover caused by rigid contact. The flexible pressure head 17 is flexibly attached to the surface of the top cover, which not only enhances the stability of the pressing but also reduces the formation of indentations, effectively protecting the appearance and structural integrity of the top cover. After the rotary motor 18 at the bottom of the workbench 1 is started, it drives the drive wheel 19 to rotate through the output shaft. The drive wheel 19 drives multiple driven wheels 21 to rotate synchronously through the belt 20. The elastic groove 3 connected to the upper end of the driven wheel 21 through the fixed seat rotates together, thereby driving the sodium battery in the placement groove 2 to rotate as a whole. At the same time, the hydraulic cylinder 4 on the other side of the workbench 1 pushes the slider 6 to move laterally through the hydraulic rod 5. The electric telescopic rod 7 at the upper end of the slider 6 can adjust the height of the connecting rod 8, so that the welding head 9 on the connecting rod 8 is precisely aligned with the welding joint between the top cover and the shell. During the rotation of the sodium battery, the welding head 9 continuously outputs welding energy to achieve continuous welding of the circumferential weld, ensuring the uniformity and reliability of the welding.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
