Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a sodium battery welding device. Background Technology

[0002] A sodium battery is a secondary battery that uses sodium metal or sodium alloy as the negative electrode material and sodium-containing compounds as the positive electrode material. Charge transfer and battery charging and discharging processes are achieved through the insertion and extraction of sodium ions between the positive and negative electrodes.

[0003] A search revealed Chinese patent application CN202320293581.7, which discloses an aluminum shell welding device for sodium-ion batteries. The device includes a frame, a rotating base, and a rectangular tube. The rotating base is rotatably mounted on the frame, and support arms are symmetrically mounted on the top side of the rotating base. Clamping plates are slidably mounted on two opposite sides inside the rectangular tube. U-shaped arms are mounted on both opposite sides of the rectangular tube and are rotatably connected to the support arms. When an aluminum shell is placed inside the rectangular tube, two pneumatic cylinders simultaneously move the clamping plates, fixing the aluminum shell inside the rectangular tube. This achieves the limiting and fixing of aluminum shells of different specifications. During the welding process, in addition to multi-angle adjustments to the laser welding head, a first motor drives the rotating base to rotate and adjust the welding angle, and a second motor rotates the rectangular tube to perform welding on its ends.

[0004] In the aforementioned prior art, the main method is to use a motor to drive the threaded rod to adjust the height and moving distance of the laser welding head, thereby enabling the laser welding head to weld the casing of the sodium battery. Although this adjustment welding method is relatively convenient, this welding device is only suitable for welding conventional rectangular sodium battery casings. When welding irregularly shaped casings or when welding at specific angles on the inner wall of the casing, it is inconvenient to adjust the angle of the laser welding head, making the use of the welding device rather inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a sodium battery welding device that solves the problem that existing sodium battery welding devices are inconvenient to weld at certain special angles inside irregularly shaped sodium battery casings, making the welding device less convenient to use.

[0007] The above technical solution involves using a first electric telescopic rod to move a clamping plate, which then clamps and restricts the sodium battery casing.

[0008] As a preferred embodiment of the above technical solution, a second electric telescopic rod is fixedly connected to the upper end of the first support plate, and a push plate is fixedly connected to the end of the second electric telescopic rod away from the first support plate.

[0011] The above technical solution restricts the movement of the push plate by allowing the slider to slide within the slide rail.

[0012] As a preferred embodiment of the above technical solution, a third electric telescopic rod is fixedly connected to the upper end of the push plate, and a connecting plate is fixedly connected to the upper end of the third electric telescopic rod.

The two ends of the fourth electric telescopic rod are fixedly connected to adapters, and the ends of the adapters away from the fourth electric telescopic rod are rotatably connected to the second support plate and the rotating plate, respectively.

[0017] Through the above technical solution, the rotating plate is pulled by the operation of the fourth electric telescopic rod, thereby allowing the rotating plate to adjust the welding angle of the laser welder with the assistance of the adapter rod.

[0018] As a preferred embodiment of the above technical solution, a third motor is fixedly connected to the lower end of the rotating plate, and a laser welder is fixedly connected to the output shaft of the third motor.

[0019] The above technical solution allows for the adjustment of the rotation angle of the laser welder by operating a third motor.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a sodium battery welding device, including a base 1, a first motor 11 fixedly connected to the lower side of the base 1, and a turntable 12 fixedly connected through the output shaft of the first motor 11 through the base 1. A first support plate 13 is fixedly connected to one end of the base 1, and an adjustment component is provided on the upper end of the base 1. The adjustment component includes an adjustment component fixedly connected to the upper end of the base 1, and a fixing plate 21 provided at both ends of the turntable 12. The lower end of the fixing plate 21 is fixedly connected to the base 1, and a first electric telescopic rod 22 is fixedly connected to the upper end of the fixing plate 21. A clamping plate 23 is fixedly connected to the end of the first electric telescopic rod 22 away from the fixing plate 21. By adjusting the structure, the height and angle of the laser welder 219 can be adjusted to improve the welding range of the welding device, enabling welding of sodium battery shells with special shapes and positions, and improving the ease of use of the welding device.

[0029] like Figure 1 As shown, a second electric telescopic rod 24 is fixedly connected to the upper end of the first support plate 13, and a push plate 25 is fixedly connected to the end of the second electric telescopic rod 24 away from the first support plate 13. The push plate 25 is moved and adjusted by activating the second electric telescopic rod 24.

[0030] like Figure 1 and Figure 4 As shown, a slider 26 is fixedly connected to the lower end of the push plate 25, and a slide rail 27 is sleeved on the lower end of the slider 26. The lower end of the slide rail 27 is fixedly connected to the base 1. When the push plate 25 moves, it drives the slider 26 to slide in the slide rail 27. The slider 26 and the slide rail 27 assist the movement of the push plate 25.

[0031] like Figure 1As shown, a third electric telescopic rod 28 is fixedly connected to the upper end of the push plate 25, and a connecting plate 29 is fixedly connected to the upper end of the third electric telescopic rod 28. The connecting plate 29 can be moved and adjusted by activating the third electric telescopic rod 28.

[0032] like Figure 3 As shown, a second motor 210 is fixedly connected to one end of the connecting plate 29, and a threaded rod 211 is fixedly connected through the output shaft of the second motor 210 through the connecting plate 29. The end of the threaded rod 211 away from the second motor 210 is rotatably connected inside the connecting plate 29, and a threaded plate 212 is threadedly engaged with the outer side of the threaded rod 211. A second support plate 213 is fixedly connected to the end of the threaded plate 212 away from the connecting plate 29. By starting the second motor 210, its output shaft drives the threaded rod 211 to rotate. The threaded engagement between the threaded rod 211 and the threaded plate 212 causes the threaded plate 212 to drive the second support plate 213 to move and adjust.

[0033] like Figure 1 and Figure 2 As shown, a rotating plate 214 is inserted inside the end of the second support plate 213 away from the connecting plate 29, and adapter rods 215 are fixedly connected to both sides of the rotating plate 214. The end of the adapter rod 215 away from the rotating plate 214 is rotatably connected to the second support plate 213, and a fourth electric telescopic rod 216 is provided at the upper end of the rotating plate 214. The two ends of the fourth electric telescopic rod 216 are fixedly connected to adapter pieces 217, and the ends of the adapter pieces 217 away from the fourth electric telescopic rod 216 are rotatably connected to the second support plate 213 and the rotating plate 214 respectively. By activating the fourth electric telescopic rod 216, it pulls the rotating plate 214 with the assistance of the adapter pieces 217, thereby allowing the rotating plate 214 to rotate with the assistance of the adapter rods 215, and adjusting the angles of the third motor 218 and the laser welder 219.

[0034] like Figure 1 As shown, a third motor 218 is fixedly connected to the lower end of the rotating plate 214, and a laser welder 219 is fixedly connected to the output shaft of the third motor 218. By starting the third motor 218, its output shaft can drive the laser welder 219 to rotate and adjust.

[0035] Working principle: When welding the sodium battery casing using the welding device, the sodium battery casing to be welded is first placed on the turntable 12. Then, the first electric telescopic rods 22 on both sides are activated. After the first electric telescopic rods 22 are activated with the support of the fixed plate 21, the output shaft drives the clamping plate 23 to move and clamp the sodium battery casing. Then, with the support of the first support plate 13, the second electric telescopic rod 24 is activated. After the second electric telescopic rod 24 is activated, it extends and pushes the push plate 25 to move with the assistance of the slider 26 and the slide rail 27. While the push plate 25 is moving, it drives the third electric telescopic rod 28 and the connecting plate 29 to move. When the third motor 218 and the laser welder 219 move directly above the sodium battery casing to be welded, the second electric telescopic rod 24 is closed. Then, the third electric telescopic rod 28 and the second motor 210 are activated simultaneously. The operation of the third electric telescopic rod 28 drives the connecting plate 29 to move. The vertical adjustment is achieved by connecting plate 29, third motor 218, and laser welder 219. After the second motor 210 is started, its output shaft drives the threaded rod 211 to rotate. The threaded engagement between the threaded rod 211 and the threaded plate 212 causes the threaded plate 212 to move the second support plate 213. This allows the second support plate 213 to drive the third motor 218 and laser welder 219 for horizontal adjustment. After adjustment, the operation of the fourth electric telescopic rod 216, with the assistance of the adapter 217, pulls the upper end of the rotating plate 214. This allows the rotating plate 214, with the assistance of the adapter rod 215, to drive the third motor 218 and laser welder 219 for angle adjustment. At this time, the third motor 218 can also be started to drive the laser welder 219 for rotational adjustment. After adjustment, the laser welder 219 can be used to weld the casing of the sodium battery.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
