[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please see the attached Figure 1-5 The aluminum shell cylindrical battery sealing welding fixture in the embodiment of the present invention includes a base plate 1, a clamping mechanism 2 and a transmission mechanism 4 are connected to the base plate 1, the clamping mechanism 2 is connected to a plurality of cylindrical batteries 3, and the transmission mechanism 4 is used to drive the clamping mechanism 2 to clamp and fix the plurality of cylindrical batteries 3. The clamping mechanism 2 and the transmission mechanism 4 can clamp and fix the plurality of cylindrical batteries 3. This solution takes a group of 6 cylindrical batteries as an example, and the clamping and fixation are achieved by the clamping mechanism 2 and the transmission mechanism 4.

[0030] The clamping mechanism 2 includes a limiting plate 21 and a fixing plate 23, which are spaced apart and used to place the cylindrical battery 3;

[0031] The limiting plate 21 is provided with a plurality of limiting grooves 26, which are all V-shaped and continuously arranged. The limiting grooves 26 are arranged in a V-shape, so that batteries of different sizes can be limited, thereby improving the practicality and universality of the clamping mechanism 2. The plurality of limiting grooves 26 are continuously arranged. On the one hand, under the condition of the same length of the limiting plate 21, more cylindrical batteries 3 can be limited to improve the utilization rate. On the other hand, a certain distance can be maintained between the plurality of cylindrical batteries 3, which is convenient for orderly welding and improves the stability and consistency of welding. A plurality of push rods 25 are connected to the upper sliding surface, and one end of each of the push rods 25 is fixedly connected to an arc plate 24. The arc plates 24 correspond to the plurality of limiting grooves 26 one by one. A cylindrical battery 3 is limited and fixed between an arc plate 24 and a limiting groove 26. The other ends of the push rods 25 extend out of the fixing plate 23 and are fixedly connected to the supporting spring 22. One end of the push rod 25 is in the shape of an elongated cylinder, and the other end is in the shape of a flat cylinder. The flat cylinder is used to limit the elongated cylinder, such as Figure 2 As shown, the support spring 22 is connected between the flat cylinder and one side of the fixed plate 23. The support spring 22 can absorb and reduce the pressure to a certain extent, so that the appropriate pressure is maintained between the pushing rod 25 and the cylindrical battery 3, avoiding excessive squeezing of the cylindrical battery 3, and thus enhancing the stability of the pushing rod 25 and the arc plate 24 pressing the cylindrical battery 3.

[0032] An anti-slip pad 27 is fixedly connected to one side of the arc plate 24. The arc plate 24 is made of a flexible metal sheet with good flexibility, so that the arc plate 24 can adapt to and fit cylindrical batteries of different sizes to achieve effective limiting and fixation. The arc plate 24 can increase the force-bearing area of ​​the cylindrical battery 3. On the one hand, it maintains the stability of the pressure, and on the other hand, it prevents the cylindrical battery 3 from being deformed due to local pressure. The anti-slip pad 27 is made of silicone, which can enhance the tightness and stability of the connection between the arc plate 24 and the cylindrical battery 3, and prevent the cylindrical battery 3 from self-rotating during the clamping process.

[0033] like Figure 2 and Figure 3As shown, taking a group of 6 cylindrical batteries as an example, the transmission mechanism 4 includes a first connecting rod 45, two U-shaped plates 46 and a second connecting rod 47. The two U-shaped plates 46 are respectively fixedly connected to the two ends of the plurality of pushing rods 25. The two U-shaped plates 46 are fixedly connected to the two pushing rods 25 at both ends. The first connecting rod 45 and the second connecting rod 47 are connected between the two U-shaped plates 46. One end of the first connecting rod 45 and the second connecting rod 47 are respectively connected to the middle of the two U-shaped plates 46, and the other ends of the first connecting rod 45 and the second connecting rod 47 are respectively connected to the middle of the plurality of pushing rods 25. The transmission mechanism 4 also includes a connecting rod The connecting plate 44 has connecting seats 48 fixedly connected at both ends of one side of the connecting plate 44. The two connecting seats 48 are respectively connected to the first connecting rod 45 and the second connecting rod 47, that is, the first connecting rod 45 is connected to the pushing rod 25 in the middle near the middle of the second connecting rod 47, and the second connecting rod 47 is connected to the pushing rod 25 in the middle near the middle of the first connecting rod 45. Then, the first connecting rod 45 and the second connecting rod 47 are staggered and mutually limited, which can improve the stability of the connection between the first connecting rod 45 and the second connecting rod 47 and the two connecting seats 48, make the force more uniform, and facilitate the effective clamping and fixation of each circular battery 3.

[0034] A support plate 42 is fixedly connected to the base plate 1, and one end of the support plate 42 is fixedly connected to a micro-electric cylinder 41. The output end of the micro-electric cylinder 41 extends out of the support plate 42 and is fixedly connected to one side of the connecting plate 44. The micro-electric cylinder 41 drives the connecting plate 44 and the pushing rod 25 connected thereto to move through its piston to clamp and fix the round battery 3.

[0035] A slider 43 is fixedly connected to the bottom of the connecting plate 44, and a slide groove 49 is fixedly connected to the bottom plate 1 between the support plate 42 and the fixed plate 23. The slide groove 49 and the slider 43 are connected to each other. The slide groove 49 is used to guide the connecting plate 44, thereby improving the stability of the movement of the connecting plate 44, avoiding its skewness, and improving the stability of the operation of the clamping mechanism 2 and the transmission mechanism 4.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
