[0002] Battery consistency refers to the convergence of key characteristic parameters of a group of lithium-ion batteries. It is a relative concept; there is no such thing as the most consistent, only more consistent. For multiple strings of cells in the same battery pack, each parameter should ideally fall within a relatively small range.

[0003] In the related art, the production of soft battery packs mainly relies on manual production, which not only has low production efficiency, but also does not pay attention to consistency issues during manual production, resulting in poor consistency of the produced soft battery packs, thereby resulting in a short service life of the soft battery packs.

The first transport component 310 and the second transport component 320 are parallel to each other. The loading module 200 and the testing module 100 are located on one side of the first transport component 310 and the second transport component 320. The tab cutting module 400, the stacking module 500, and the welding module 600 are located between the first transport component 310 and the second transport component 320.

[0077] based on Figure 1 Schematic soft battery pack manufacturing equipment, the first embodiment of the present application provides a soft battery pack manufacturing method. Figure 2 , Figure 2 The following is a flow chart of the steps of the soft battery pack manufacturing method. The soft battery pack manufacturing method of the embodiment of the present application may include but is not limited to the following steps:

[0078] Step S210, controlling the test module to perform electrical testing on the soft battery cell to obtain the test internal resistance, test capacity, and test open circuit voltage of the soft battery cell;

[0079] It is worth noting that the tested internal resistance refers to the internal resistance of the soft battery cell 800 when it is working; the tested capacity refers to the ability of the soft battery cell 800 to store electrical energy, usually measured in milliampere-hours (mAh); and the tested open circuit voltage refers to the difference between the positive electrode potential and the negative electrode potential when the soft battery cell 800 is in a disconnected state.

[0080] Step S220, obtaining an internal resistance difference based on the tested internal resistance and the preset internal resistance, obtaining a capacity difference based on the tested capacity and the preset capacity, and obtaining a voltage difference based on the tested open-circuit voltage and the preset open-circuit voltage;

[0081] In one embodiment, multiple soft battery cells 800 are tested in advance, and the average value of the tested internal resistances of the multiple soft battery cells 800 is used as the internal resistance difference; the average value of the tested capacities of the multiple soft battery cells 800 is used as the preset capacity; and the average value of the tested open-circuit voltages of the multiple soft battery cells 800 is used as the preset open-circuit voltage.

[0082] In one embodiment, multiple soft battery cells 800 are tested in advance, and the mode of the tested internal resistances of the multiple soft battery cells 800 is used as the internal resistance difference; the mode of the tested capacities of the multiple soft battery cells 800 is used as the preset capacity; and the mode of the tested open-circuit voltages of the multiple soft battery cells 800 is used as the preset open-circuit voltage.

[0083] Step S230, obtaining a consistency score of the soft battery cell based on the internal resistance difference, the capacity difference, and the voltage difference;

[0084] Step S240: If the consistency score is greater than a preset threshold, control the loading module to transport the soft battery cell to the first transport assembly;

[0085] Step S250: If the consistency score is less than or equal to a preset threshold, control the loading module to transport the soft battery cell to the second transport assembly;

[0086] In one embodiment, the loading module 200 is a loading robot.

[0087] Step S260, controlling the tab cutting module to cut the tabs of the soft battery cells in the transport module;

[0088] Step S270: Control the stacking module to stack a preset number of soft battery cells in the first transport assembly to obtain a first soft battery module; control the stacking module to stack a preset number of soft battery cells in the second transport assembly to obtain a second soft battery module;

[0089] It is noteworthy that, since the first flexible battery module is composed of flexible cells 800 with a consistency score greater than a preset threshold, the tested internal resistance, tested capacity, and tested open-circuit voltage of each flexible cell 800 from the first flexible battery module are relatively close, thus the first flexible battery module has good consistency. The second flexible battery module is composed of flexible cells 800 with a consistency score less than or equal to the preset threshold, thus the tested internal resistance, tested capacity, and tested open-circuit voltage of each flexible cell 800 from the second flexible battery module are relatively close, thus the second flexible battery module has good consistency.

[0090] It should be noted that those skilled in the art can set the preset threshold according to actual needs.

[0091] Step S280 , controlling the welding module to perform welding processing on the first battery module to obtain a first soft battery pack; controlling the welding module to perform welding processing on the second battery module to obtain a second soft battery pack.

[0092] The soft battery pack manufacturing method according to the first embodiment of the present application, through steps S210 to S280, first controls the testing module 100 to perform electrical testing on the soft battery cells 800 to obtain the test internal resistance, test capacity, and test open-circuit voltage of the soft battery cells 800; controls the tab cutting module 400 to cut the tabs of the soft battery cells 800 in the transport module; controls the stacking module 500 to stack a preset number of soft battery cells 800 in the first transport component 310 to obtain a first soft battery module; controls the stacking module 500 to stack a preset number of soft battery cells 800 in the second transport component 320 to obtain a second soft battery module; controls the welding module 600 to weld the first battery module to obtain a first soft battery pack; and controls the welding module 600 to weld the second battery module to obtain a second soft battery pack. In this way, automated production is achieved and production efficiency is improved. Furthermore, a first soft battery module is obtained from a preset number of soft cells 800 in the first transport component 310. The consistency scores of the preset number of soft cells 800 in the first transport component 310 are all greater than a preset threshold. Therefore, the tested internal resistance, tested capacity, and tested open-circuit voltage of each soft cell 800 in the first transport component 310 are relatively close. Thus, the consistency of each soft cell 800 in the first soft battery pack is high, which can improve the service life of the first soft battery pack. A second soft battery module is obtained from a preset number of soft cells 800 in the second transport component 320. The consistency scores of the preset number of soft cells 800 in the second transport component 320 are all less than or equal to the preset threshold. Therefore, the tested internal resistance, tested capacity, and tested open-circuit voltage of each soft cell 800 in the second transport component 320 are relatively close. Thus, the consistency of each soft cell 800 in the second soft battery pack is high, which can improve the service life of the second soft battery pack.

[0093] In one embodiment, step S230, obtaining a consistency score of the soft battery cell 800 based on the internal resistance difference, the capacity difference, and the voltage difference, includes:

[0094] The consistency score is calculated based on the scoring calculation formula; the calculation formula is:

[0095] F = a*x+b*y+c*z;

[0096] Among them, F represents the consistency score, x represents the internal resistance difference, a represents the weight of the internal resistance difference, y represents the capacity difference, b represents the weight of the capacity difference; z represents the voltage difference, and c represents the weight of the voltage difference.

[0097] It is worth noting that the consistency score is calculated by the scoring calculation formula, and the closer the consistency scores of the two soft batteries 800 are, the higher the consistency of the two soft batteries 800 is. It should be noted that those skilled in the art can set the values ​​of a, b, and c according to actual conditions.

[0098] In one embodiment, referring to Figure 3 , Figure 3 Schematic diagram of the structure of the tab cutting module 400 according to an embodiment of the present application. The tab cutting module 400 includes a clamping assembly 430, a positioning platform 410, a visual inspection assembly 440, and a cutting assembly 420. The positioning platform 410 is provided with a positioning groove 411.

[0099] Step S260, controlling the tab cutting module to cut the tabs of the soft battery cells in the transport module, includes the following steps:

[0100] Step S261, controlling the clamping assembly to clamp the soft battery cell from the transport module and move the soft battery cell to the positioning groove;

[0101] Step S262, controlling the visual inspection component to take photos of the soft battery cell located in the positioning groove to determine the cutting position on the soft battery cell;

[0102] Step S263 : Based on the cutting position, control the cutting assembly to cut the soft battery cell.

[0103] Specifically, the tab is located at one end of the soft battery cell 800. When the clamping assembly 430 transports the soft battery cell 800 to the positioning groove 411, the end of the soft battery cell 800 without the tab is abutted against the bottom of the positioning groove 411, and the end with the tab is located outside the positioning groove 411, and the clamping assembly 430 keeps clamping the soft battery cell 800 to fix the soft battery cell 800. Then, the visual inspection assembly 440 takes a photo of the soft battery cell 800 located in the positioning groove 411 for inspection, and determines the cutting position in the tab that needs to be cut based on the preset length. Then, the cutting assembly 420 is controlled to cut at the cutting position of the tab, thereby completing the cutting process.

[0104] It is worth noting that during the production process of the soft battery cell 800, due to process defects, the lengths of the pole ears of the soft battery cell 800 are different. In order to stack multiple soft battery cells 800 in subsequent steps, the pole ears of the soft battery cell 800 are cut through steps S261 to S263 so that the pole ears of each soft battery cell 800 have the same length.

[0105] In some embodiments, the stacking module 500 includes a glue application assembly, a film tearing assembly, and a stacking assembly;

[0106] In step S270, controlling the stacking module to stack a preset number of soft battery cells in the first transport assembly to obtain a first soft battery module includes the following steps:

[0107] Step S271, controlling the adhesive laminating assembly to adhere the adhesive tape to the side surface of the soft battery cell in the first transport assembly;

[0108] Step S272, controlling the film tearing assembly to tear the tape on the soft battery cell;

[0109] In one embodiment, the film tearing assembly includes a film tearing clamp arm (not shown in the figure) and a film tearing drive unit (not shown in the drawing), the film tearing drive unit is connected to the two film tearing clamp arms, and the film tearing drive unit is used to drive the two film tearing clamp arms to move, so that the two film tearing clamp arms are close to the film of the tape on one side of the soft battery cell 800, and then the two film tearing clamp arms are close to each other so that the two film tearing clamp arms clamp the film, and then the film tearing drive unit drives the two film tearing clamp arms away from the soft battery cell 800 to separate the film from the tape; then drives the two clamp arms close to the film of the tape on the other side of the soft battery cell 800 to complete the film tearing of the tape on the other side, thus completing the film tearing process.

[0110] It should be noted that, during the film tearing process of the film tearing assembly, the soft battery cell 800 needs to be fixed. For example, the soft battery cell 800 can be clamped by a robotic arm to achieve the fixing of the soft battery cell 800.

[0111] Step S273 , controlling the stacking assembly to stack a preset number of soft battery cells with adhesive tapes to obtain a first soft battery module.

[0112] It is worth noting that, through steps S217 to S273, the soft battery cells 800 in the first transport component 310 are stacked, and the soft battery cells 800 are glued together with tape, so that the soft battery cells 800 are firmly connected.

[0113] It should be noted that the second soft battery module is obtained by stacking the soft battery cells 800 in the second transport assembly 320 by the stacking module 500. The process of obtaining the second soft battery module is the same as that of obtaining the first soft battery module, which will not be repeated here.

[0120] Step S2715 , controlling the second adsorption unit to attach the second adhesive tape to the second side surface of the soft battery cell.

[0121] It is worth noting that, in the embodiment of the present application, through steps S2711 to S2715, the first adhesive tape is applied to the first side of the soft battery cell 800, and the second adhesive tape is applied to the second side of the soft battery cell 800.

The third side and the fourth side are opposite each other. The thickness of the soft battery cell 800 is relatively thin, and the area of ​​the third and fourth sides is very small. Therefore, only the first and second sides need to be adhesively applied.

[0122] In one embodiment, referring to Figure 5 , Figure 5 The following is a schematic diagram of the structure of a stacking assembly according to an embodiment of the present application. The stacking assembly includes a stacking platform 5250, a stacking robot 5260, and a push plate drive unit 5200. The stacking platform 5250 is surrounded by a first push plate 5210, a second push plate 5220, a third push plate 5230, and a fourth push plate 5240. The first push plate 5210 is opposite and parallel to the second push plate 5220, and the third push plate 5230 is opposite and parallel to the fourth push plate 5240. The first push plate 5210, the second push plate 5220, the third push plate 5230, and the fourth push plate 5240 are each equipped with a push plate drive unit 5200.

[0125] Step S2732: Control the push plate driving unit to control the first push plate and the second push plate to move closer to each other, and control the push plate driving unit to control the third push plate and the fourth push plate to move closer to each other, so as to gather the soft battery cells to obtain a first soft battery module.

[0126] Through the above-mentioned steps S2731 and S2732, the stacking robot 5260 is first controlled to transport a preset number of soft battery cells 800 to the stacking platform 5250, and arrange each soft battery cell 800 in the stacking platform 5250, and then the push plate driving unit 5200 is controlled to control the first push plate 5210 and the second push plate 5220 to approach each other, and the push plate driving unit 5200 is controlled to control the third push plate 5230 and the fourth push plate 5240 to approach each other, so that each soft battery cell 800 is gathered, that is, the tapes of each soft battery cell 800 are pasted together, thereby obtaining a first soft battery module.

[0127] It should be noted that, in order to facilitate subsequent welding processing, the preset order means that the positive electrode ear of the j-th soft battery cell 800 in the first soft battery module is adjacent to the negative electrode ear of the j+1-th soft battery cell 800, and the negative electrode ear of the j-th soft battery cell 800 is adjacent to the positive electrode ear of the j+1-th soft battery cell 800, where j is a positive integer less than N, and N is a preset number.

[0131] Specifically, the bending assembly includes a bending clamp arm 611 and a bending drive unit 612, which are arranged on one side of the roller 621. The bending drive unit 612 drives the bending clamp arm 611 to clamp the tab. After the bending clamp arm 611 clamps the tab, the bending drive unit 612 drives the bending clamp arm 611 to rotate, thereby driving the tab to rotate, so that the tab of the soft battery cell 800 is bent, and the bent portion of the tab is parallel to the end face of the first battery module.

[0132] Step S282: Control the roller drive assembly to drive the roller to abut against the end surface of the first battery module, and control the roller drive assembly to drive the roller to roll back and forth on the end surface of the first battery module to press the bent portion of the tab against the end surface of the first battery module;

[0133] Step S283, controlling the welding assembly to weld the bent portion of the negative electrode tab of the i-th soft battery cell in the first battery mold to the bent portion of the positive electrode tab of the (i+1)-th soft battery cell;

[0134] Step S284, control the welding assembly to weld the bent portion of the positive electrode ear of the first soft battery cell to the positive electrode adapter, and control the welding assembly to weld the bent portion of the negative electrode ear of the Nth soft battery cell to the negative electrode adapter to obtain a first soft battery pack, wherein i is a positive integer less than N, and N is a preset number.

[0135] It is worth noting that through steps S280 to S284, the tab of the soft battery cell 800 is first bent, and the bent portion of the tab is parallel to the end face of the first battery module, and then the roller drive assembly 622 is controlled to drive the roller 621 to roll back and forth on the end face of the first battery module to press the bent portion of the tab against the end face of the first battery module, thereby improving the welding quality in the subsequent process. Then, the welding assembly is controlled to weld the bent part of the negative ear of the i-th soft battery cell 800 in the first battery module to the bent part of the positive ear of the i+1-th soft battery cell 800, the welding assembly is controlled to weld the bent part of the positive ear of the first soft battery cell 800 to the positive electrode adapter, and the welding assembly is controlled to weld the bent part of the negative ear of the N-th soft battery cell 800 to the negative electrode adapter, thereby realizing the series connection between the soft battery cells 800 in the first battery module, thereby obtaining the first soft battery pack, realizing the automated production of the first soft battery pack, and improving production efficiency.

[0136] It should be noted that the process of obtaining the second soft battery pack is the same as the process of obtaining the first soft battery pack, which will not be described in detail.
