For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] At present, after the winding or lamination of the battery cells is completed, the battery cells are usually directly processed in the next step. The battery cells with bad size cannot be found in time, which easily leads to the battery cells with bad size continuing to carry out subsequent operations such as lug welding, increasing the risk of battery scrapping. In addition, if the size of the battery cells after winding or lamination is directly detected, the battery cells are in a loose state at this time. There is a large deviation between the size of the battery cells in the loose state and the size of the battery cells completed in the subsequent hot pressing process, and the size of the battery cells in the loose state has a large fluctuation, and the relevant size of the battery cells cannot be accurately detected, which reduces the accuracy of the size detection of the battery cells, and easily leads to the battery cells with bad size continuing to carry out subsequent processing operations.

[0044] In order to solve the above problems, Figure 1 to Figure 4 As shown, this embodiment provides a battery cell detection mechanism 10, which includes a driving component 1, a pressing component 2 and a detection component 3, wherein the pressing component 2 is located above the conveyor belt 30 for conveying the battery cell 20, the pressing component 2 is connected to the output end of the driving component 1, the driving component 1 can drive the pressing component 2 to press against the battery cell 20 on the conveyor belt 30, and the detection component 3 is used to detect the size of the battery cell 20 pressed by the pressing component 2. The battery cell detection mechanism 10 provided in this embodiment detects the size of the battery cell 20 conveyed on the conveyor belt 30, so as to facilitate timely discovery of defective battery cells 20, avoid subsequent processes from continuing to process defective battery cells 20, and reduce the scrapping of batteries. In addition, by pressing the battery cell 20 located on the conveyor belt 30 with the pressing component 2, the detection component 3 detects the size of the compacted battery cell 20, ensuring that the size of the detected battery cell 20 is consistent with the size of the battery cell 20 after subsequent hot pressing, thereby accurately detecting the relevant size of the battery cell 20 and ensuring the accuracy of the size detection of the battery cell 20.

[0045] It should be noted that, in the present embodiment, the detection of the size of the battery cell 20 by the detection component 3 includes detecting the spacing between the tabs 201 of the battery cell 20, the margins of the tabs 201, the size of the tabs 201, etc. However, it is not limited to this, and the detection component 3 can also detect other relevant sizes of the battery cell 20. In addition, by detecting the size of the battery cell 20 by the detection component 3, it is convenient to correct the defective battery cell 20 in time, ensure that the relevant size of the battery cell 20 meets the required size, and facilitate the subsequent processing of the corrected battery cell 20.

The above arrangement, by designing the connecting plate 21 into a frame form and using the transparent pressing plate 22 to press the battery cell 20, avoids the obstruction of the detection of the pressing assembly 3 by the pressing assembly 2, so that the detection assembly 3 can detect the size of the battery cell 20 through the avoidance hole 211 and the transparent pressing plate 22 in turn.

[0057] In this embodiment, if Figure 1 to Figure 3 As shown, the battery cell detection mechanism 10 also includes a light source assembly 5, which is mounted on the lower end surface of the fixed frame 41.

Specifically, the buffer stopper can be in the form of a limiting rubber block.

[0060] In order to facilitate understanding of the battery cell detection mechanism 10 disclosed in this embodiment, Figure 1 to Figure 3 The specific working process of the battery cell detection mechanism 10 is described as follows:

[0061] When the battery cell 20 is wound or stacked and is conveyed by the conveyor belt 30 to the bottom of the pressing component 2 (i.e., the detection position), the conveyor belt 30 stops conveying the battery cell 20, and then the driving component 1 drives the pressing component 2 to descend until the transparent pressing plate 22 presses on the battery cell 20. At this time, the multiple CCD cameras 31 in the detection component 3 jointly take pictures of the pressed battery cell 20 for detection. When the detection component 3 completes the detection, the driving component 1 drives the pressing component 2 to rise and reset, and the conveyor belt 30 continues to convey the battery cell 20 that has passed the detection.

[0062] The present embodiment further provides a battery processing device, which includes a conveyor belt 30 and the above-mentioned battery cell detection mechanism 10, wherein the conveyor belt 30 is used to convey the battery cells 20 for unloading, and the battery cell detection mechanism 10 is used to detect the size of the battery cells 20 conveyed by the conveyor belt 30. By applying the above-mentioned battery cell detection mechanism 10, the battery processing device is convenient for timely detection of defective battery cells 20, avoiding the subsequent process of continuing to process the defective battery cells 20, reducing the scrapping of batteries, and can ensure that the size of the detected battery cell 20 is consistent with the size of the battery cell 20 after subsequent hot pressing, thereby accurately detecting the relevant size of the battery cell 20 and ensuring the accuracy of the size detection of the battery cell 20.
