[0048] In the specific working process, the battery cell 7 is transferred to the accompanying fixture 6 of the first step conveyor line 2 through the loading component 1, and then the first step conveyor line 2 works. When the accompanying fixture 6 with the battery cell 7 moves to the loading code scanning component 21, the loading code scanning component 21 can identify the identity of the current battery cell 7 and bind the identification result to the battery cell 7; then the accompanying fixture 6 with the battery cell 7 continues to move, and when it moves to the X-Ray imaging component 22, the X-Ray imaging component 22 takes a perspective photo of the battery cell and determines whether the battery cell 7 is qualified, and binds the determination result to the battery cell identity.

[0049] In this embodiment, the accompanying jig 6 moves with the first stepping conveyor line 2 or the second stepping conveyor line 4, and no additional tray is required, which reduces the cost. Moreover, since the accompanying jig 6 moves with the conveyor line and does not need to be moved up and down again, high-precision transmission and positioning of the battery cell 7 can be achieved.

[0052] Specifically, the first fixing plate 61, the second fixing plate 62 and the third fixing plate 63 are all strip structures, and the three are arranged in parallel and spaced apart. The second fixing plate 62 is located between the first fixing plate 61 and the third fixing plate 63. Both ends of the second fixing plate 62 are recessed downwardly. A first slider is provided at the first recess. The two first sliders are respectively provided with a first longitudinal positioning block 66 and a second longitudinal positioning block 67; in this way, the first slider slides at the first recess, which can drive the first longitudinal positioning block 66 and the second longitudinal positioning block 67 to move, so that the longitudinal length of the above-mentioned area is changed.

[0056] The structure of the second stepping conveying line 4 is the same as that of the first stepping conveying line 2 .

[0057] Specifically, the conveyor belt 23 includes two belts arranged in parallel, with a gap between the two belts.

[0063] In this embodiment, when the battery cell 7 flows to the X-Ray imaging component 22, the X-Ray imaging component 22 takes a perspective photo of the battery cell and determines whether the battery cell 7 is qualified, and binds the determination result to the identity of the battery cell; then, when it continues to flow to the unloading and scanning component 41, after scanning the code there, when the battery cell is qualified, unloading is achieved through the unloading component 5, and conversely, when the battery cell 7 is defective, unloading is achieved through the defective product unloading component 8; this setting method realizes automatic classification of the battery cell 7.

[0074] Specifically, the flat panel detector 224 and the X-ray source 225 are used to take a perspective view of the inside of the battery cell, and determine whether the battery cell is good or defective based on the perspective view. The first vertical moving module 222 can adjust the height of the flat panel detector 224, and the second vertical moving module 223 can adjust the height of the X-ray source 225, and then adjust its distance from the tested battery cell, so as to achieve different magnifications.
