[0047] In one embodiment, see Figure 1 A plurality of moving blocks 12 are arranged at intervals on the magnetic suspension guide rail 11, each moving block 12 is connected to a battery fixture 2, and the position adjustment of the plurality of moving blocks 12 can flexibly control the distance between adjacent battery fixtures 2 to improve the efficiency of battery 100 detection on the battery fixture 2.

[0048] The detection machine provided in the embodiment of the present application includes a conveying mechanism 1, which includes a magnetic levitation rail 11 and a moving block 12, and the moving block 12 is movably arranged on the magnetic levitation rail 11; a battery fixture 2, which is connected to the moving block 12 and is used to load a battery 100; a detection mechanism 3, which is arranged around the magnetic levitation rail 11 and has a detection position. When the moving block 12 drives the battery fixture 2 to the detection position, the detection mechanism 3 is used to detect the battery 100, and the moving block 12 moves on the magnetic levitation rail 11 to sequentially convey the battery fixture 2 to the detection position of the detection mechanism 3 through the movement of the moving block 12, thereby improving the efficiency of the detection mechanism 3 in detecting the battery 100 on the battery fixture 2, and can ensure the accuracy of the detection mechanism 3 in detecting the battery 100.

[0049] In one embodiment, a plurality of batteries 100 can be arranged on a battery fixture 2, and the detection mechanism 3 includes a plurality of detection units 31 spaced and distributed around the magnetic suspension guide rail 11;

[0051] In a specific embodiment, see Figure 1 , four batteries 100 are loaded on a battery fixture 2, and the detection mechanism 3 includes four detection units 31 spaced around the magnetic suspension rail 11, that is, the number of batteries on a battery fixture 2 corresponds to the number of detection units 31 around the magnetic suspension rail 11, and each detection unit 31 detects one battery 100, that is, Figure 1 The detection unit 31 at the lower left of the center detects the first battery on the battery fixture 2. Figure 1 The detection unit 31 on the upper left of the middle detects the second battery on the battery fixture 2. Figure 1 The detection unit 31 in the upper right center detects the third battery on the battery fixture 2. Figure 1 The detection unit 31 at the lower right center detects the fourth battery on the battery fixture 2 to improve the efficiency of the detection mechanism 3 in detecting the battery 100 .

[0052] In one embodiment, the detection mechanism 3 is an X-ray detection mechanism.

[0053] In this embodiment, by utilizing the characteristics of X-rays, the X-ray detection mechanism can penetrate the material of the battery pole piece and detect the structure and defects inside the battery. In this way, problems with the pole piece in the battery, such as pores, cracks and foreign matter in the pole piece, can be quickly and accurately discovered, ensuring the performance stability and safety of the battery.

[0054] In addition, X-ray detection can also be used to detect internal short circuits, electrode asymmetry, impurities, and electrolyte leakage within the battery, which can also ensure the performance and safety of the battery.

[0055] In one embodiment, see Figure 7 The detection mechanism 3 includes a detection frame 32, a light-emitting tube 33 and a detector 34. The light-emitting tube 33 and the detector 34 are connected to the detection frame 32 at intervals, and a detection position is formed between the light-emitting tube 33 and the detector 34.

[0056] In this embodiment, when the moving block 12 moves on the magnetic levitation rail 11 to transport the battery fixture 2 to the detection position of the detection mechanism 3, the light-emitting tube 33 emits X-rays to the battery 100 on the battery fixture 2. After passing through the battery 100, the X-rays can be imaged on the detection frame 32 to detect whether the battery 100 has defects, thereby improving the efficiency of battery 100 detection.

[0057] In one embodiment, see Figure 7 The detection mechanism 3 includes a driving member 35 and a base 36. A slide rail 321 is provided on the detection frame 32, and a slide groove is provided on the base 36. The driving member 35 is connected to the slide rail 321 and is used to drive the slide rail 321 to slide in the slide groove.

[0058] In this embodiment, the detection frame 32 can move on the base 36 through the slide rail 321, and can further drive the light-emitting tube 33 and the detector 34 to move, so that the light-emitting tube 33 can emit X-rays at different positions of the battery 100 and on batteries of different sizes, thereby ensuring the comprehensiveness of the detection of the battery 100 by the detection mechanism 3 and improving the accuracy of the detection of the battery 100 by the detection mechanism 3.

[0059] In one embodiment, see Figure 1 and Figure 2 The detection machine further includes a feeding mechanism 4, which is arranged around the magnetic suspension guide rail 11;

[0060] The loading mechanism 4 includes a loading track 41 and a loading transfer structure 42 . The loading track 41 is used to transport the tray cup 200 , which can carry the battery 100 . The loading transfer structure 42 is used to transfer the battery 100 in the tray cup 200 to the battery fixture 2 .

[0061] In this embodiment, the battery 100 is Figure 1 The loading port in the loading is loaded onto the loading track 41, and the loading track 41 is provided with a loading station. The loading transfer structure 42 can be a loading robot. When the battery 100 is transported to the loading station through the loading track 41, the loading robot grabs the battery 100 and transfers the battery 100 to the battery fixture 2. The movement of the moving block 12 transports the battery fixture 2 to the detection position of the detection mechanism 3 in turn and performs detection, thereby ensuring the efficiency of the battery 100 from loading to detection.

[0062] In one embodiment, see Figure 1 , further comprising a material discharge mechanism 5, the material discharge mechanism 5 being arranged around the magnetic suspension guide rail 11;

[0063] The unloading mechanism 5 includes an unloading track 51 and an unloading transfer structure 52 . The unloading track 51 is used to transport the support cup 200 , and the unloading transfer structure 52 is used to transfer the battery 100 on the battery fixture 2 to the support cup 200 .

[0064] The unloading track 51 has an unloading station, and the unloading transfer structure 52 can be an unloading robot. When the battery 100 is tested, the unloading robot grabs the battery 100 and transfers the battery 100 from the battery fixture 2 to the unloading station of the unloading track 51. The battery 100 is transported on the unloading track 51 and passes through Figure 1 The material is unloaded from the unloading port in the equipment and transferred to the logistics line outside the equipment, ensuring the efficiency of the battery 100 from detection to unloading.

[0065] In one embodiment, see Figure 1 The unloading track 51 is connected to the loading track 41 through the middle track, and the tray cup 200 that does not carry the battery 100 in the loading track 41 can be transported to the unloading track 51 through the middle track.

[0066] In this embodiment, the cup 200 carrying the battery 100 can be a real cup, and the cup 200 not carrying the battery 100 can be an empty cup; the real cup carries the battery loading and moves to the loading position under the conveying action of the loading track 41, the loading transfer structure 42 transfers the battery 100 to the battery fixture 2, and the empty cup continues to be conveyed along the loading track 41 and the middle track to the unloading track 51. When the empty cup moves to the unloading position, the unloading transfer structure 52 places the tested battery 100 into the empty cup. At this time, the empty cup becomes a real cup, and the real cup continues to be conveyed until unloading, thereby improving the utilization efficiency of the cup 200.

[0067] In one embodiment, see Figures 2 to 5 The loading transfer structure 42 includes a rotating member 421, a mounting plate 422 and at least one chuck 423, the chuck 423 is connected to the mounting plate 422, and the rotating member 421 is connected to the mounting plate 422 and is used to drive the mounting plate 422 and the chuck 423 to rotate.

[0068] In this embodiment, the rotating member 421 in the loading transfer structure 42 can be a flipping mechanism such as a motor or a gear. When the rotating member 421 drives the mounting plate 422 and the chuck 423 to rotate, the orientation of the chuck 423 can be adjusted, thereby realizing the setting direction of the battery 100 in the chuck 423.

[0069] In one embodiment, the battery 100 in the cup 200 can be placed vertically to ensure the stability of the cup 200 in carrying the battery 100; and the battery 100 on the battery fixture 2 can be placed horizontally to facilitate the arrangement of the battery 100 on the battery fixture 2; after the rotating member 421 rotates the clamp 423 from vertical to horizontal, the battery 100 can be efficiently placed on the battery fixture 2 while facilitating the clamp 423 to clamp the battery 100 from the cup 200, such as Figures 3 to 5 shown.

[0070] In one embodiment, the unloading transfer structure 52 may also be provided with the same flipping mechanism as the loading transfer structure 42 , so as to facilitate the transfer of the battery 100 from the battery fixture 2 to the support cup 200 .

[0072] In this embodiment, when the clamp 423 clamps the battery 100, in order to avoid a hard collision between the clamp 423 and the battery 100, the elastic deformation of the elastic member 424 can be used to drive the clamp 423 to move, so that the clamp 423 is set as a movable clamp. On the basis of ensuring the efficiency of the clamp 423 in clamping the battery 100, it is avoided that the clamp 423 collides with the battery 100 and causes damage to the battery 100.

[0073] The groove and the guide rail 4221 can be slidably matched, so that the guide rail 4221 can provide guidance for the movement of the clamp 423, thereby preventing the clamp 423 from tilting and ensuring the accuracy of the clamp 423 in clamping the battery 100.
