Description

Technical Field

[0002] The cells used in photovoltaic cells need to be coated, and during the production of the cells, the defects of the cells need to be detected. Currently, in this field, cell defects are generally identified manually and then the cells are sorted, but this method is too dependent on manual labor, has low reliability, and is inefficient. In order to solve the above problems, some existing technologies use X-ray scanning technology to detect defects in cells, such as the Chinese patent document with announcement number CN 117174617 A. This patent uses a rotating method to detect defects in the cells located on the flip wheel in turn. Compared with the manual identification method, the efficiency and reliability are improved, but the efficiency is still relatively low. Utility Model Content

[0038] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0039] Please refer to Figures 1-4A battery cell inspection device includes a first conveying component 1, a second conveying component 2, a visual recognition component 3 and a sorting mechanism 4; in a first direction, the first conveying component 1 and the second conveying component 2 are arranged in sequence, and a detection gap 5 is formed between the first conveying component 1 and the second conveying component 2, and the visual recognition component 3 is arranged toward the detection gap 5; in a second direction, a sorting end 40 of the sorting mechanism 4 is arranged opposite to the conveying surface of the second conveying component 2; the sorting end 40 of the sorting mechanism 4 can move along the second direction and / or the third direction.

[0040] It is worth noting that the first direction refers to the conveying direction of the first conveying component 1 and the second conveying component 2, the second direction refers to the vertical direction, and the third direction refers to another horizontal direction that is perpendicular to the first direction and the second direction at the same time, that is, the first direction, the second direction and the third direction constitute a three-axis coordinate system.

[0041] It can be understood that, through the cooperation of the first conveying component 1 and the second conveying component 2, a detection gap 5 is formed between the two, so that when the battery cell 7 passes through the detection gap 5, the visual recognition component 3 can obtain the surface image of the battery cell 7 from the detection gap 5, and then judge whether the battery cell 7 is qualified. If the battery cell 7 is judged to be unqualified, the unqualified battery cell 7 will be sorted to a designated location by the sorting mechanism 4, while the qualified battery cell 7 will continue to be conveyed and stacked. The utility model can quickly detect defects in the battery cell 7 with high continuity and recognition efficiency, and has high accuracy and reliability in identifying defects in the battery cell 7.

[0042] In some embodiments, the visual recognition component 3 includes an image acquisition end 31 ; the image acquisition end 31 forms an angle α with the first direction that is less than 90°. Optionally, the angle α is between 0° and 90°. Preferably, the angle α is 66°. The angle α formed between the image acquisition end 31 and the first direction enables the image acquisition end 31 of the visual recognition component to capture a complete surface image of the battery cell 7 through the detection gap 5 .

[0043] In some embodiments, a gantry 6 is further included; the sorting mechanism 4 is mounted on the gantry 6 and is connected to the gantry 6 so as to be relatively movably connected.

[0044] In some embodiments, the sorting mechanism 4 includes an adsorption assembly 41, a lifting assembly 42 distributed along the second direction, and a transverse movement assembly 43 distributed along the third direction; the adsorption assembly 41 is transmission-connected to the movable end of the lifting assembly 42; and the lifting assembly 42 is transmission-connected to the movable end of the transverse movement assembly 43. The lifting assembly 42 and the transverse movement assembly 43 are provided to drive the adsorption assembly 41 to move along the second direction or the third direction, thereby adsorbing and transporting unqualified battery cells 7 located on the second conveying assembly 2 to a designated area. Specifically, the transverse movement assembly 43 is used to drive the lifting assembly 42 and the adsorption assembly 41 to move along the third direction. Preferably, the transverse movement assembly 43 is a slide.

[0045] In some embodiments, the lifting assembly 42 includes an extension member 421 and a lifting drive member 422. The extension member 421 is arranged along the second direction. The lifting drive member 422 is connected to one end of the extension member 421, and the other end of the extension member 421 is connected to the movable end of the transverse movement assembly 43. The provision of the extension member 421 is used to reduce the distance between the lifting drive member 422 and the conveying surface of the second conveyor assembly 2, thereby facilitating the adsorption of the battery cell 7. Preferably, the lifting drive member 422 is a linear cylinder.

[0046] In some embodiments, the adsorption assembly 41 includes a bracket 411, a first adsorption member 412, and a second adsorption member 413.

[0047] In some embodiments, in the second direction, the side of the adsorption plate 4112 away from the frame 4111 forms an adsorption groove 44 with the adsorption surface of the first adsorption member 412 and the adsorption surface of the second adsorption member 413. The adsorption groove 44 is provided to form an adsorption cavity between the battery cell 7 and the first adsorption member 412 and the second adsorption member 413 after the adsorption plate 4112 contacts the battery cell 7, thereby ensuring adsorption pressure.

[0048] In some embodiments, the visual recognition assembly 3 includes an image recognition member 32 and an adjustment bracket 33; the image recognition member 32 and the adjustment bracket 33 are hingedly connected to adjust the angle α between the image recognition member 32 and the first direction. Specifically, in the third direction, two opposing side walls of the adjustment bracket 33 each have an arcuate slot 35. One end of the image recognition member 32 is hingedly connected to the adjustment bracket 33, and the other end of the image recognition member 32 is slidably connected to the arcuate slot 35 via a limiting post 34 to adjust the angle α between the image recognition member 32 and the first direction.

[0049] In some embodiments, in the first direction, the visual recognition component 3 is offset from the detection gap 5, and the image acquisition end 31 of the visual recognition component 3 is disposed toward the detection gap 5. The purpose of the offset between the visual recognition component 3 and the detection gap 5 is to form an angle α between the orientation of the image acquisition end 31 of the visual recognition component 3 and the first direction, thereby enabling rapid acquisition of image data of the battery cell 7.

[0050] In some embodiments, a storage rack 8 is further included; in the third direction, the storage rack 8 is disposed on one side of the second conveyor assembly 2, and the sorting end 40 of the sorting mechanism 4 can be disposed opposite the storage rack 8.
