Some embodiments, referring to fig. 1 to 4, the present application provides a tab folding detection device, including: the battery tab shaping device comprises a shaping module 110, a marking module 120 and a detection module 130, wherein the shaping module 110 is used for carrying out initial dislocation shaping on tabs of a battery cell to form a dislocation area 220, the marking module 120 is used for carrying out color marking on the dislocation area 220 to form a continuous color block 230 on the dislocation area 220, the shaping module 110 is used for carrying out secondary dislocation shaping on the dislocation area 220 to enable the continuous color block 230 to be changed into a separated color block 240, and the detection module 130 is used for carrying out folding detection on the separated color block 240 to obtain a folding detection result.
In the exemplary embodiment, when the battery cell is a multi-tab battery cell, after the pole pieces are formed into the battery cell through winding or lamination processes, a plurality of positive electrode tabs and a plurality of negative electrode tabs may exist on one battery cell, in a subsequent process flow, the plurality of positive electrode tabs may be connected with each other to form a positive electrode of the battery cell, and the plurality of negative electrode tabs may be connected with each other to form a negative electrode of the battery cell. Before connecting, need detect the anodal utmost point ear and the negative pole utmost point ear of electric core, detect each utmost point ear on the electric core promptly, guarantee that utmost point ear does not produce and turns over a book, prevent that a plurality of anodal utmost point ears or a plurality of negative pole utmost point ears contact failure when interconnect. Between a plurality of anodal utmost point ears of electric core or between a plurality of negative pole utmost point ears be parallel to each other and be interval distribution under the condition of not connecting, not mutual contact between different anodal utmost point ears or the negative pole utmost point ear, but can shelter from each other between a plurality of anodal utmost point ears or between a plurality of negative pole utmost point ears this moment, the detection that inconvenient utmost point ear was turned over and is rolled over.
The utmost point ear that detection device detected is rolled over to utmost point ear is the same utmost point ear of organizing that needs interconnect, like a plurality of positive pole utmost point ears or a plurality of negative pole utmost point ears, positive pole utmost point ear and negative pole utmost point ear position on electric core can set up wantonly, for example, positive pole utmost point ear and negative pole utmost point ear setting are in same one side of electric core, perhaps positive pole utmost point ear sets up at the top of electric core, and negative pole utmost point ear sets up in the bottom of electric core. The positive electrode tab and the negative electrode tab in the embodiment are arranged on the same side of the battery cell, and when the positive electrode tab or the negative electrode tab is detected respectively, the detection flow of the tab folding detection device is the same, so that the detection process of the tab folding detection device is described in detail by taking the detection flow of the positive electrode tab as an example.
The battery cell comprises a battery cell main body 210, a positive electrode lug and a negative electrode lug, and the positive electrode lug is subjected to dislocation shaping through the shaping module 110, so that a plurality of positive electrode lugs are attached to each other, the tail end region of the positive electrode lugs is exposed on the detection surface, and a dislocation region 220 after dislocation shaping is formed. The size of dislocation region 220 is relevant with the degree of inclination of positive pole utmost point ear for electric core main part 210 during dislocation plastic, and different degrees of inclination can make the terminal area of positive pole utmost point ear that exposes different, and the degree of inclination can be according to the type of positive pole utmost point ear and subsequent detection needs arbitrary setting.
The misalignment region 220 is color-marked by the marking module 120, and a continuous color patch 230 is formed on the misalignment region 220. When color marking is performed, different marking materials can be selected according to subsequent different detection modes, so that the detection module 130 can accurately identify the color marking. In the example, when the image recognition mode is used for detection, the color with larger color difference with the positive electrode lug is selected, so that the collected image data can clearly distinguish the color mark on the positive electrode lug. When a device such as a photoelectric sensor which actively emits a detection signal and detects according to a received reflection signal is used, the detection module 130 can also achieve the effect of identifying the color mark by marking the detection signal with a material having a larger difference with the absorption rate of the positive electrode tab according to the absorption rate of the positive electrode tab to the detection signal.
And then, the secondary dislocation shaping is performed on the dislocation area 220 through the shaping module 110, so that the continuous color blocks 230 are changed into separate color blocks 240.
