[0062] The present application will be described in detail below.

[0063] The preparation process of the bare battery cell includes coating, slicing, tab welding, and tab encapsulation of the positive and negative electrode raw materials, and then winding and flat pressing the wound core together with the cut membrane to form the bare battery cell. The prepared bare battery cell is loaded into an aluminum plastic shell, then side sealed, and then sealed after injecting electrolyte into the injection hole.

[0064] At present, during the process of coating and casing the bare battery cell, an upper and lower circulating line is generally used for conveying, wherein the upper layer is driven by a servo motor module, and the lower layer is driven by a servo synchronous belt return. The upper and lower circulating lines jointly convey the bare battery cell to perform one-stop coating and casing process. However, this conveying structure has low conveying efficiency, which affects the production rhythm of the overall production line.

[0065] In order to solve the problem of low rhythm in the conveying process of the existing bare battery cell, an embodiment of the present application provides a bare battery cell coating and casing production line. The bare battery cell coating and casing production line can not only be applied to the conveying and manufacturing of bare battery cells, but also be applied to other fields such as logistics and automobile manufacturing. The following description of the present application is based on the conveying of bare battery cells.

[0066] As shown in FIG. 1, the bare battery cell coating and casing production line includes a first conveying module 11, a film material conveying module 12, and a shell material conveying module 13. As shown in FIG. 2, the first conveying module 11 includes a magnetic drive conveying line 111 for conveying bare battery cells. The film material conveying module 12 is used to wrap the bare battery cells on the magnetic drive conveying line 111. The shell material conveying module 13 is arranged at the next station of the film material conveying module 12 along the conveying direction of the magnetic drive conveying line 111. As shown in FIG. 9, the shell material conveying module 13 includes a first mechanical arm 133 and at least two feeding conveying lines 131. The first mechanical arm 133 is used to load the shell on the feeding conveying line 131 into the wrapped bare battery cell.

[0067] The conveying direction of the magnetic drive conveying line 111 in the embodiment can refer to the arrow direction in FIG. 1, that is, the conveying direction of the magnetic drive conveying line 111 is from right to left. The specific direction can be determined according to the actual situation, and the embodiment of the present application does not limit it.

[0068] Referring to FIG. 3, the magnetic drive conveying line 111 includes a stator body 11111, a guide rail (not labeled in the figure), an armature winding (not labeled in the figure) arranged on the stator body 11111, and a mover body 11112. The guide rail is arranged on the stator body 11111. The armature winding can magnetically cooperate with the mover body 11112. Under the action of the armature winding, the mover body 11112 can slide on the guide rail. Since the connection structure and working principle of the magnetic drive conveying line 111 are prior art, they will not be described here.

[0069] The film material conveying module 12 in the embodiment can be a multi-degree-of-freedom mechanical arm, and the specific type can be determined according to actual conditions, which is not limited in the embodiment.

[0070] Referring to FIG. 9, two feeding conveying lines 131 are arranged side by side, and a shell for assembling a bare battery cell is placed on each feeding conveying line 131.

[0071] In the embodiment, the feeding conveying line 131 can be a roller conveying line, a belt conveying line, etc., and the specific type can be determined according to actual conditions, which is not limited in the embodiment.

[0072] In the embodiment, the first mechanical arm 133 can be a four-degree-of-freedom mechanical arm, a five-degree-of-freedom mechanical arm, etc., and the specific type can be determined according to actual conditions, which is not limited in the embodiment.

[0073] In use, when the magnetic drive conveying line 111 conveys the bare battery cell to the position of the film material conveying module 12, the film material conveying module 12 wraps the corresponding cell film on the bare battery cell, and then the magnetic drive conveying line 111 conveys the wrapped bare battery cell to the position of the shell material conveying module 13. At this time, the first mechanical arm 133 grabs the shell on the feeding conveying line 131 and assembles the corresponding shell on the wrapped bare battery cell.

[0074] In the technical scheme of the embodiment, since the magnetic drive conveying line 111 itself has a high conveying speed, the conveying efficiency of the bare battery cell 100 can be improved when the bare battery cell 100 is conveyed by the magnetic drive conveying line 111, and the production rhythm of the overall production line is effectively improved. At the same time, since the shell material conveying module 13 includes at least two feeding conveying lines 131, one of the feeding conveying lines 131 can be used for feeding, and the other feeding conveying line 131 can be used for standby. The two feeding conveying lines 131 work simultaneously to ensure that there is always a shell on the production line, and the machine does not need to be stopped when the shell on one of the feeding conveying lines 131 is used up, thereby improving the feeding rhythm and further improving the production rhythm of the overall production line.

At this time, after the first connecting conveying line 1112 is started, the bare battery cell 100 on the first connecting conveying line 1112 can be conveyed to the magnetic driving sub-conveying line 1111.

[0079] When the bare battery cell 100 on the first connecting conveying line 1112 is conveyed to the magnetic driving sub-conveying line 1111, the first connecting conveying line 1112 can be separated from the magnetic driving sub-conveying line 1111. Then, a new bare battery cell 100 is placed on the first connecting conveying line 1112, and then the first connecting conveying line 1112 is connected with the magnetic driving sub-conveying line 1111 again, so that the new bare battery cell 100 on the first connecting conveying line 1112 can be conveyed to the magnetic driving sub-conveying line 1111.
