[0022] Please refer to Figures 1 to 4 , a battery post-welding detection assembly, including a battery carrier 42 and a detection mechanism 41. The battery carrier 42 is used for clamping the battery 1; the detection mechanism 41 is located on the side of the battery carrier 42 and is arranged near the end of the battery 1 in the length direction; the battery carrier 42 includes a fixed bracket 421 and a clamping part 422. The clamping part 422 is adjustably assembled on the fixed bracket 421. The battery 1 is arranged on the clamping part 422. The clamping part 422 can be adjusted relative to the fixed bracket 421 so that the long side and the short side of the battery top cover are respectively in the detection positions. Here, the attitude of the battery 1 is adjusted by the battery carrier 42, so that the long side and the short side of the welded battery top cover can respectively reach the detection positions, and thus the same detection mechanism 41 can be used to complete the detection of the long side and the short side plates of the battery top cover, effectively saving costs.

[0023] In this embodiment, the clamping part 422 includes a fixed bottom plate 4221, which is rotatably connected to the fixed bracket 421; a support plate 4222 and a pneumatic gripper 4223 are provided on the fixed bottom plate 4221, and the battery 1 is placed on the support plate 4222 and fixed by the pneumatic gripper 4223; a first driving structure 423 is provided on the fixed bracket 421, which is used to drive the fixed bottom plate 4221 to rotate relative to the fixed bracket 421. Optionally, the first driving structure 423 includes a motor 4231 and a cross-direction gear 4232, and the fixed bottom plate 4221 is rotatably connected to the fixed bracket 421 through the cross-direction gear 4232. The motor 4231 is installed on the fixed bracket of the clamping part 422, and is used to drive the cross-direction gear 4232 to operate to realize the flipping of the fixed bottom plate 4221, thereby realizing the flipping of the battery 1 to switch the long side and the short side of the battery top cover so that they are respectively in the detection position, so as to cooperate with the detection mechanism 41 for detection.

[0024] In another embodiment, the fixed base plate 4221 can be installed on the fixed bracket 421 through a rotating shaft, and a motor is disposed on the fixed bracket 421, and the output shaft of the motor is drivingly connected to the rotating shaft.

[0025] In this embodiment, a rotating mounting seat 42211 is provided on the fixed base plate 4221, the support plate 4222 and the pneumatic gripper 4223 are installed on the first side surface 4201 of the fixed base plate 4221, the rotating mounting seat 42211 is provided on the second side surface 4202 of the fixed base plate 4221, and the rotating mounting seat 42211 is installed on the output shaft of the cross-steering gear 4232.

[0026] As Figure 1 , Figure 2 and Figure 4 As shown, a limiting notch 42221 is provided on the support plate 4222, and the battery 1 is located in the limiting notch 42221. The limiting notch 42221 is used to initially limit the battery 1 so as to cooperate with the mechanical gripper to fix the battery 1.

[0027] like Figure 1 and Figure 2 As shown, the detection mechanism 41 includes a second driving structure 411 and a moving plate 412. The second driving structure 411 is used to drive the moving plate 412 to move; the moving plate 412 is provided with a first detection module 413 and a second detection module 414. When the battery 1 is in the detection position, the battery 1 is in the detection area of ​​the first detection module 413 and the second detection module 414. The first detection module 413 and the second detection module 414 here are 3D cameras. The second driving structure 411 is a linear module. In this embodiment, the battery 1 is a blade battery, and both ends of the battery 1 in the length direction have battery top covers. Therefore, the battery post-welding detection assembly here includes two detection mechanisms 41, which are correspondingly arranged at the two ends of the battery 1 to improve the detection efficiency.

[0028] Of course, in other embodiments, the post-welding detection assembly of the battery can also be applied to the detection after the welding of the top covers of other types of square shell batteries, and the detection mechanism 41 is specifically set according to the number of top covers.

[0029] When in use, as Figure 1 shown, it is the first state of the battery carrier 42. At this time, the long side of the battery top cover is in the detection position. At this time, the second driving structure 411 drives the moving plate 412, that is, the first detection module 413 and the second detection module 414, to move along the detection direction W to complete the detection of the long side; then under the action of the first driving structure 423, the clamping part 422 flips forward along the detection direction W so that the battery carrier 42 is in the state as Figure 2 shown. At this time, the short side of the battery top cover is in the detection position. At this time, the second driving structure 411 drives the moving plate 412, that is, the first detection module 413 and the second detection module 414, to move along the detection direction W to complete the detection of the short side.

[0030] Furthermore, a linear module is arranged on the moving plate 412, and the first detection module 413 and the second detection module 414 are respectively movably assembled on the moving plate 412 through the linear module. When in use, the battery 1 is located between the first detection module 413 and the second detection module 414. The movably assembled manner of the first detection module 413 and the second detection module 414 on the moving plate 412 enables the distance between the first detection module 413 and the second detection module 414 and the battery 1 to be adjustable, which is convenient for detecting the long side and the short side.

[0031] As Figure 3 and Figure 4 shown, a bar 4211 and a limit pin 4212 are arranged on the fixed bracket 421 for limiting and fixing the bottom plate 4221. Specifically, when detecting the long side of the battery top cover, the second side surface 4202 of the fixed bottom plate 4221 abuts against the bar 4211; when detecting the short side of the battery top cover, the rotary mounting seat 42211 abuts against the limit pin 4212.
