[0036] Embodiment 1:

[0037] A power battery pack sorting device of this embodiment, such as Figure 1 and Figure 2As shown, it includes a first universal conveyor 1 and a second universal conveyor 2, the first universal conveyor 1 includes an inlet end and two outlet ends, the second universal conveyor 2 includes an inlet end and two outlet ends, the inlet end of the first universal conveyor 1 is provided with a transparent conveyor belt 3, the bottom of the transparent conveyor belt 3 is provided with a first visual inspection device 100, and the top of the first universal conveyor 1 is provided with a second visual inspection device 200; the first outlet end of the first universal conveyor 1 is connected to the inlet end of the second universal conveyor 2 through an intermediate conveyor belt 4, the top of the second universal conveyor 2 is provided with a charge and discharge limit device 5, and the first and outlet ends of the second universal conveyor 2 are provided with an outlet conveyor belt 6.

[0038] The transparent conveyor belt 3 conveys the battery pack along the first direction to the input end of the first universal conveyor device 1. The first universal conveyor device 1 can convey the battery pack along the first direction to the first output end, and convey the battery pack along the second direction to the second output end. The first output end of the first universal conveyor device 1 is connected to the intermediate conveyor belt 4, and the second output end of the first universal conveyor device 1 is connected to the NG station through the blanking slope. During the process of the battery pack being conveyed by the transparent conveyor belt 3, the bottom surface of the battery pack is photographed by the first visual inspection device 100 at the bottom of the transparent conveyor belt 3. When the battery pack is conveyed to the first universal conveyor device 1, the top and side surfaces of the battery pack are photographed by the second visual inspection device 200. The first visual inspection device 100 and the second visual inspection device 200 are both connected to an external computer. After the external computer receives the captured image, it identifies whether the appearance of the battery pack is intact through the image. Specifically, if the battery pack has no defects on its exterior, the controller controls the first universal conveyor 1 to convey the battery pack along the first direction to the intermediate conveyor 4, and further conveys the battery pack to the second universal conveyor 2 through the intermediate conveyor 4. If the battery pack has defects on its exterior, the controller controls the first universal conveyor 1 to convey the battery pack along the second direction to the NG station, and then performs a first sorting on the battery pack according to whether the exterior is defective or not.

[0039] After the battery pack with good appearance is conveyed to the second universal conveyor 2, it is connected to the interface of the battery pack through the charge and discharge limit device 5, and the battery pack is charged and discharged to detect the battery pack's power health. For battery packs with qualified power health, the second universal conveyor 2 conveys the battery pack along the first direction to the outgoing conveyor 6, and the battery pack is subsequently transported through the outgoing conveyor 6; for battery packs with unqualified power health, the second universal conveyor 2 conveys the battery pack along the second direction to the NG station, and the battery pack is sorted a second time according to the power health.

[0040] like Figure 7As shown, the first universal conveying device 1 has the same structure as the second universal conveying device 2. Taking the first universal conveying device 1 as an example, it includes a conveying table, a universal ball 300, a first direction shaft 301, a second direction shaft 302, a first direction drive motor 311, and a second direction drive motor 312. A plurality of universal balls 300 are rotatably installed in the sockets on the conveying table. A first direction shaft 301 is provided on one side of each row of universal balls 300 for rotation along the first direction. A roller in contact with the universal ball 300 is mounted on the first direction shaft 301, and the first direction shaft 301 is connected to the output shaft of the first direction drive motor 311 through a gear meshing structure. The roller on the first direction shaft 301 is driven to rotate by the first direction drive motor 311, thereby driving each row of universal balls 300 to rotate along the first direction. Similarly, a second direction rotating shaft 302 is provided on one side of each column of universal balls 300 for rotation along the second direction, and a roller in contact with the universal balls 300 is mounted on the second direction rotating shaft 302, and the second direction rotating shaft 302 is connected to the output shaft of the second direction driving motor 312 through a gear meshing structure. The second direction driving motor 312 drives the roller on the second direction rotating shaft 303 to rotate, thereby driving each column of universal balls 300 to rotate along the second direction, and finally realizing the first universal conveying device 1 to transport the battery packs along the first direction or the second direction.

Taking the first material storage turntable 9 as an example, it includes a turntable body, and four groups of radial convex ridges passing through the center of the turntable body are arranged on the turntable body along the circumferential direction. The four groups of radial convex ridges divide the top bearing surface of the turntable body into four temporary storage areas. In each temporary storage area, a radial slide groove is arranged along the radial direction passing through the center of the turntable body. A push plate is slidably arranged in the radial slide groove. The bottom of the push plate extends to the bottom of the turntable body and is connected to the radial cylinder. The battery pack is transported to a temporary storage area by the conveyor belt, and the turntable body rotates to temporarily store the battery pack to prevent the battery pack from piling up on the first universal transfer device 1 and the second universal transfer device 2. When the temporary storage area rotates to align with the conveyor belt, the radial cylinder drives the push plate to be pushed out, and then pushes the battery pack in the temporary storage area onto the conveyor belt for subsequent transmission.
