Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a cell assembly method, electronic device, and computer-readable storage medium. Background Technology

[0002] In related technologies, with the development of the new energy and automotive industries, the demand for battery packs is increasing. For example, the power battery pack, as the core energy storage unit of electric vehicles, plays a crucial role. It is mainly responsible for storing and providing electrical energy to drive the electric motor, thus enabling the vehicle to move. Battery packs are generally divided into rigid battery packs and flexible battery packs. Because the outer shell of a rigid battery pack is made of metal or other hard materials, it provides good mechanical strength and structural protection, effectively resisting external impacts and compression. Therefore, it has gained widespread recognition and favor in the fields of new energy vehicles and energy storage. The core component of a rigid battery pack is the rigid battery module, which is composed of multiple rigid battery cells. In related technologies, rigid battery modules are mainly obtained by manually assembling multiple rigid battery cells, which is very inefficient. Summary of the Invention

[0085] Reference Figure 1 , Figure 1This is a simplified structural diagram of a battery cell assembly device used to perform the battery cell assembly method according to an embodiment of this application. The battery cell assembly device includes a transport module 100, a material carrier tray 200, a robotic arm module 300, a flipping module 400, an adhesive application module 500, and a stacking module 600. The robotic arm module 300, flipping module 400, adhesive application module 500, and stacking module 600 are disposed on one side of the transport module 100, and are arranged sequentially along the length of the transport module 100. The flipping module 400 includes a first robotic arm unit and a first vision unit. The material carrier tray 200 is used to place rigid battery cells 700, and the end face of the rigid battery cell 700 is provided with a positive electrode tab and a negative electrode tab. The material carrier tray 200 is movably mounted on the transport module 100. The transport module 100 is used to transport the material carrier tray 200. The robotic arm module 300 is used to transport the rigid battery cell 700 to the material carrier tray 200. The transport module 100 transports the material carrier tray 200 so that the material carrier tray 200 can move along the length of the transport module 100, allowing different modules to perform different actions on the rigid battery cells 700 on the material carrier tray 200. When the transport module 100 transports the material carrier tray 200 to the adjacent first vision unit, the first vision unit takes a picture of the rigid battery cells 700 on the material carrier tray 200 to obtain a first image. Then, based on the first image, the flipping module 400 confirms whether there exists a rigid battery cell 700 whose positive electrode tab is adjacent to the positive electrode tab of an adjacent rigid battery cell 700. If so, it controls the first robotic arm unit to flip the rigid battery cell 700 so that the positive electrode tab of any rigid battery cell 700 is adjacent to the negative electrode tab of an adjacent rigid battery cell 700, and the negative electrode tab of any rigid battery cell 700 is adjacent to the positive electrode tab of an adjacent rigid battery cell 700. The adhesive application module 500 is used to apply adhesive to the rigid battery cell 700. After the adhesive application is completed, the stacking module 600 stacks and combines the rigid battery cells 700 to obtain a rigid battery module.

[0086] It should be noted that the rigid battery module is only a semi-finished product in the production process of rigid battery packs. After obtaining the rigid battery module, subsequent processes require other steps, such as installing a casing on the rigid battery module, fixing the casing, and welding the rigid battery cells 700 in the rigid battery module to connect them in series. This application will not elaborate on the production process after obtaining the rigid battery module.

[0087] The first aspect of this application is based on... Figure 1 The schematic diagram of the battery cell assembly device proposes a battery cell assembly method. (Refer to...) Figure 2 , Figure 2This is a schematic flowchart illustrating the steps of a battery cell assembly method according to an embodiment of this application. The steps of the battery cell assembly method according to an embodiment of this application include, but are not limited to, steps S210 to S270.

[0088] Step S210: When the material carrier plate is near the robot arm module, control the robot arm module to transport a preset number of rigid battery cells onto the material carrier plate, and arrange the rigid battery cells in sequence.

[0089] It is worth noting that the material carrier tray 200 is provided with a preset number of contoured grooves. The rigid battery cell 700 is square in shape, and the shape of the contoured grooves matches the shape of the rigid battery cell 700, so that the rigid battery cell 700 can move smoothly with the material carrier tray 200 when the transport module 100 transports the material carrier tray 200. The preset number is the number of rigid battery cells 700 in the rigid battery module, so one rigid battery cell 700 on one material carrier tray 200 can produce one rigid battery module.

[0090] It is worth noting that the rigid battery cells 700 are arranged in a row on the physical support disk to facilitate the execution of subsequent processes.

[0091] Step S220: Control the transport module to transport the material carrier tray to the flipping module, and control the first vision unit to acquire the first image of the material carrier tray;

[0092] Step S230: The first robotic arm unit based on the first image control flipping module flips the rigid battery cell so that the positive electrode of any rigid battery cell is adjacent to the negative electrode of the adjacent rigid battery cell, and the negative electrode of any rigid battery cell is adjacent to the positive electrode of the adjacent rigid battery cell.

[0093] It should be noted that in the rigid battery module, each rigid cell 700 needs to be soldered in a subsequent process to connect them in series. To facilitate this soldering process, the positive tab of any rigid cell 700 must be adjacent to the negative tab of the adjacent rigid cell 700, and the negative tab of any rigid cell 700 must be adjacent to the positive tab of the adjacent rigid cell 700. (Refer to...) Figure 3 , Figure 3 for Figure 2A schematic diagram of the processing in step S230. When the robotic arm module 300 transports the rigid battery cell 700 onto the physical support plate, it cannot sense the positions of the positive and negative tabs of the rigid battery cell 700. Therefore, in the physical support plate, there may be a situation where the positive tab of a certain rigid battery cell 700 is adjacent to the negative tab of an adjacent rigid battery cell 700, and the negative tab of the same rigid battery cell 700 is adjacent to the positive tab of an adjacent rigid battery cell 700. Therefore, it is necessary to identify the rigid battery cell 700 through the first image and control the first robotic arm unit to flip the rigid battery cell 700 so that the positive tab of the rigid battery cell 700 is adjacent to the negative tab of an adjacent rigid battery cell 700, and the negative tab of the same rigid battery cell 700 is adjacent to the positive tab of an adjacent rigid battery cell 700, so as to facilitate the subsequent series connection between the various rigid battery cells 700.

[0094] It should be noted that adjacent rigid battery cells 700 refer to rigid battery cells 700 that are adjacent to each other. For example, the material carrier tray 200 has four rigid battery cells 700, which are arranged in a row as the first, second, third, and fourth rigid battery cells 700. For the first rigid battery cell 700, its adjacent rigid battery cell 700 is the second rigid battery cell 700; and for the second rigid battery cell 700, its adjacent rigid battery cells 700 are the first and third rigid battery cells 700.

[0095] Step S240: Control the transport module to transport the material carrier tray to one side of the adhesive application module;

[0096] It is worth noting that in step S230, after the flipping process is completed, the first vision unit is controlled to acquire an image of the rigid battery cell 700 on the material carrier tray 200 again to determine whether there is a situation where the positive electrode tab of any rigid battery cell 700 is adjacent to the positive electrode tab of an adjacent rigid battery cell 700. If not, the transport module 100 is controlled to transport the material carrier tray 200 to one side of the adhesive application module 500.

[0097] Step S250: Control the adhesive application module to apply adhesive to the rigid battery cell;

[0098] Step S260: After the adhesive application is completed, the control transport module transports the material carrier tray to one side of the stacking module.

[0099] Step S270: Control the stacking module to stack and combine the various rigid cells to obtain a rigid battery module.

[0100] It is worth noting that, referring to Figure 4 , Figure 4This is a simplified structural diagram of the stacking module 600. The stacking module 600 includes a stacking platform 610 and a stacking robot assembly 620. In step S270, the stacking robot assembly 620 transports the rigid battery cells 700 from the material carrier tray 200 to the stacking platform 610, ensuring that the arrangement order of the rigid battery cells 700 on the stacking platform 610 is the same as the arrangement order of the rigid battery cells 700 on the material carrier tray 200. The stacking module 600 also includes four push plates: a first push plate 631, a second push plate 632, a third push plate 633, and a fourth push plate 634. Each push plate is located on the stacking platform, with the first push plate 631 and the second push plate 632 being opposite and parallel, and the third push plate 633 and the fourth push plate 634 being opposite and parallel. The first push plate 631 and the third push plate 633 are adjacent and perpendicular to each other. Each push plate is connected to a drive cylinder 640, which is used to drive the corresponding push plate to move so that the first push plate 631 and the second push plate 632 can move closer or further away from each other, and the third push plate 633 and the fourth push plate 634 can move closer or further away from each other. During stacking, the stacking steps are as follows: First, the rigid battery cells 700 on the material carrier tray 200 are transported to the stacking platform 610 by the stacking robot assembly 620, and each rigid battery cell 700 is located between the first push plate 631 and the second push plate 632, and each rigid battery cell 700 is located between the third push plate 633 and the fourth push plate 634. Then, the first push plate 631 and the second push plate 632 are driven to move closer to each other so that each rigid battery cell 700 is gathered and arranged neatly. Then, the third push plate 633 and the fourth push plate 634 are driven to move closer to each other, and the first push plate 631 and the second push plate 632 are driven closer to each other, thereby squeezing the rigid battery cells 700 to obtain a rigid battery module.

[0101] The battery cell assembly method of this application embodiment, through the above steps S210 to S270, firstly, when the material carrier 200 is adjacent to the robot arm module 300, controls the robot arm module 300 to transport a preset number of rigid battery cells 700 onto the material carrier 200, and arranges the rigid battery cells 700 in sequence; then controls the transport module 100 to transport the material carrier 200 to the flipping module 400, controls the first vision unit to acquire a first image of the material carrier 200; based on the first image, controls the flipping module 400 to flip the rigid battery cells 700, so that the positive electrode tab of any rigid battery cell 700 is adjacent to the negative electrode tab of the adjacent rigid battery cell 700, so as to facilitate the subsequent welding process. Then, the control transport module 100 transports the material carrier tray 200 to one side of the adhesive application module 500; the control adhesive application module 500 applies adhesive to the rigid battery cells 700; after the adhesive application is completed, the control transport module 100 transports the material carrier tray 200 to one side of the stacking module 600; the control stacking module 600 stacks and combines the rigid battery cells 700 to obtain a rigid battery module. Thus, this application achieves automated production of rigid battery modules, eliminating the need for manual labor and improving production efficiency.

[0102] In one embodiment, the end face of the rigid battery cell 700 is further provided with a first marking portion 710 and a second marking portion 720, the first marking portion 710 surrounding the positive electrode tab and the second marking portion 720 surrounding the negative electrode tab; see reference Figure 5 , Figure 5 for Figure 2 A schematic diagram of a specific process for step S230. The specific process of step S230 may include, but is not limited to, steps S510 to S530.

[0103] Step S510: Obtain the first position information of the first rigid battery cell 700 based on the first image; the first position information includes the position information of the first identification part and the second identification part of the first rigid battery cell;

[0104] In one embodiment, the first identification part 710 and the second identification part 720 are different colors, for example, the first identification part 710 is red and the second identification part 720 is green. Therefore, by performing image processing on the first image, the position information of the first identification part 710 and the second identification part 720 of the rigid battery cell 700 can be obtained.

[0105] Step S520: Obtain the i-th position information of the i-th rigid battery cell based on the first image; the i-th position information includes the position information of the first and second identifiers of the i-th rigid battery cell;

[0106] Step S530: Based on the (i-1)th position information, the i-th position information is detected and processed. If the position of the first identifier of the (i-1)th rigid battery cell is adjacent to the position of the first identifier of the i-th rigid battery cell, and the position of the second identifier of the (i-1)th rigid battery cell is adjacent to the position of the second identifier of the i-th rigid battery cell, the first robotic arm unit is controlled to flip the i-th rigid battery cell so that the position of the first identifier of the (i-1)th rigid battery cell is adjacent to the position of the second identifier of the i-th rigid battery cell, and the position of the second identifier of the (i-1)th rigid battery cell is adjacent to the position of the first identifier of the i-th rigid battery cell; where i is 2, 3, ..., N; N is a preset number.

[0107] It is worth noting that when it is detected that the position of the first marking part 710 of the (i-1)th rigid battery cell 700 is adjacent to the position of the first marking part 710 of the i-th rigid battery cell 700, and the position of the second marking part 720 of the (i-1)th rigid battery cell 700 is adjacent to the position of the second marking part 720 of the i-th rigid battery cell 700, the first robotic arm unit is controlled to flip the i-th rigid battery cell 700. During the flipping process, the side of the i-th rigid battery cell 700 with the first marking part 710 and the second marking part 720 is kept facing upward, and then the i-th rigid battery cell 700 is rotated 180 degrees, thereby realizing the interchange of the positions of the first marking part 710 and the second marking part 720 in the i-th rigid battery cell 700.

[0108] In one embodiment, using the first image, a first distance is calculated between the first marking portion 710 of the i-th rigid battery cell 700 and the first marking portion 710 of the (i-1)-th rigid battery cell 700, and a second distance is calculated between the first marking portion 710 of the i-th rigid battery cell 700 and the second marking portion 720 of the (i-1)-th rigid battery cell 700. If the first distance is less than the second distance, it indicates that the position of the first marking portion 710 of the (i-1)-th rigid battery cell 700 is adjacent to the position of the first marking portion 710 of the i-th rigid battery cell 700, and the position of the second marking portion 720 of the (i-1)-th rigid battery cell 700 is adjacent to the position of the second marking portion 720 of the i-th rigid battery cell 700.

[0109] If the first distance is greater than the second distance, it means that the position of the first marking part 710 of the (i-1)th rigid battery cell 700 is adjacent to the position of the second marking part 720 of the i-th rigid battery cell 700, and the position of the second marking part 720 of the (i-1)th rigid battery cell 700 is adjacent to the position of the first marking part 710 of the i-th rigid battery cell 700.

[0110] It is worth noting that, since there may be situations where the positions of multiple rigid battery cells 700 are unfavorable for subsequent soldering, the position information of the first marking portion 710 and the second marking portion 720 of the first rigid battery cell 700 is first determined. Then, the subsequent rigid battery cells 700 are flipped sequentially using the first marking portion 710 and the second marking portion 720 of the first rigid battery cell 700. Specifically, after step S510, steps S520 to S530 are repeated to ensure that the position of the first marking portion 710 of each rigid battery cell 700 is adjacent to the position of the second marking portion 720 of the adjacent rigid battery cell 700, and the position of the second marking portion 720 of each rigid battery cell 700 is adjacent to the position of the first marking portion 710 of the adjacent rigid battery cell 700. Since the first marking part 710 surrounds the positive electrode tab and the second marking part 720 surrounds the negative electrode tab, it is equivalent to realizing that the positive electrode tab of any rigid battery cell 700 is adjacent to the negative electrode tab of the adjacent rigid battery cell 700, and the negative electrode tab of any rigid battery cell 700 is adjacent to the positive electrode tab of the adjacent rigid battery cell 700, so as to facilitate the series connection between each rigid battery cell 700 in the subsequent process flow.

[0111] In one embodiment, reference is made to Figure 6 , Figure 6 This is a schematic diagram of a sub-process of the cell assembly method according to an embodiment of this application. Figure 6 The illustrated process flow is executed before step S220. Specifically, steps S610 to S620 are included, but are not limited to, preceding step S220.

[0112] Step S610: Control the first vision unit to acquire the second image of the material carrier plate;

[0113] Step S620: Based on the second image, the rigid battery cell is detected. If the first marking part or the second marking part is not located on the end face of the rigid battery cell, the first robotic arm unit is controlled to flip the rigid battery cell so that the first marking part and the second marking part of the rigid battery cell are located on the end face of the rigid battery cell.

[0114] It is worth noting that when the robotic arm module 300 transports the rigid battery cell 700 onto the material carrier tray 200, there may be a situation where the side of the rigid battery cell 700 with the positive and negative tabs is not facing upwards. To ensure that the side of the rigid battery cell 700 with the positive and negative tabs faces upwards, this embodiment controls the first vision unit to acquire a second image of the material carrier tray 200 through steps S610 to S620, and performs detection processing on the rigid battery cell 700 based on the second image to detect whether there is a case where the upward-facing side of the rigid battery cell 700 is missing the first marking portion 710 and... If the second marking portion 720 exists, it indicates that the side of the rigid battery cell 700 with the first marking portion 710 and the second marking portion 720 is not facing upwards, that is, the first marking portion 710 and the second marking portion 720 of the rigid battery cell 700 are not located on the end face of the rigid battery cell 700. Then, the first robotic arm unit is controlled to flip the rigid battery cell 700 so that the side of the rigid battery cell 700 with the first marking portion 710 and the second marking portion 720 faces upwards, which is equivalent to making the first marking portion 710 and the second marking portion 720 of the rigid battery cell 700 located on the end face of the rigid battery cell 700.

[0115] In one embodiment, reference is made to Figure 7 , Figure 7 This is a simplified structural diagram of the adhesive application module 500 according to an embodiment of this application. The adhesive application module 500 includes a cleaning component 510, an adhesive application component 520, and a film removal component 540, which are arranged sequentially. The cleaning component 510 is used to perform plasma cleaning on the rigid battery cell 700, the adhesive application component 520 is used to apply adhesive tape to the side of the rigid battery cell 700, and the film removal component 540 is used to remove the protective film from the adhesive tape.

[0116] Reference Figure 8 , Figure 8 for Figure 2 A schematic diagram of a specific process for step S250. Step S250 may include, but is not limited to, steps S810 to S850.

[0117] Step S810: Control the cleaning assembly to perform plasma cleaning on the hard battery cell;

[0118] Step S820: Control the transport module to transport the material carrier tray to one side of the adhesive application assembly;

[0119] Step S830: Control the adhesive application assembly to apply the tape to the side of the rigid battery cell;

[0120] Step S840: Control the transport module to transport the material carrier tray to one side of the film-tearing assembly;

[0121] Step S850: Control the film-peeling assembly to peel off the tape on the rigid battery cell.

[0122] In this embodiment, through steps S810 to S850, the cleaning component 510 is first controlled to perform plasma cleaning on the rigid battery cell 700 to ensure that the rigid battery cell 700 is dry, clean, and free of oil, dust, and other impurities. Then, the transport module 100 is controlled to transport the material carrier tray 200 to one side of the adhesive application component 520. The adhesive application component 520 then applies adhesive tape to the side of the rigid battery cell 700. The transport module 100 then transports the material carrier tray 200 to one side of the film-peeling component 540, which peels off the protective film from the adhesive tape on the rigid battery cell 700. This completes the adhesive application process. Applying adhesive to the rigid battery cell 700 provides heat insulation and electrical insulation, preventing high temperatures or current leakage from the battery cell to the external environment and reducing the occurrence of safety accidents.

[0123] In one embodiment, reference is made to Figure 9 , Figure 9 This is a simplified structural diagram of the adhesive application assembly 520 according to an embodiment of this application. The adhesive application assembly 520 includes a first driving unit 5210, a second driving unit 5220, a third driving unit 5230, a first adsorption unit 5240, a second adsorption unit 5250, a first clamping unit 5231, a first tape cutting unit 5280, a first tape releasing unit 5260, a second tape cutting unit 5290, and a second tape releasing unit 5270. The first driving unit 5210 is connected to the first adsorption unit 5240 and is used to drive the first adsorption unit 5240 to move. The second driving unit 5220 is connected to the second adsorption unit 5250 and is used to drive the second adsorption unit 5250 to move. The third driving unit 5230 is connected to the first clamping unit 5231 and is used to drive the first clamping unit 5231 to move.

[0124] Reference Figure 10 , Figure 10 for Figure 8 A schematic diagram of a specific process for step S830. Step S830 may include, but is not limited to, steps S1010 to S1070.

[0125] Step S1010: Control the third drive unit to control the first clamping unit to clamp the first side and the second side of the rigid battery cell, and control the third drive unit to control the first clamping unit to drive the rigid battery cell to rise; wherein, the first side and the second side of the rigid battery cell are opposite to each other.

[0126] It is worth noting that the rigid battery cell 700 is rectangular in shape, with its first and second sides facing away from each other. Since no adhesive is required on the first and second sides, the third drive unit 5230 controls the first clamping unit 5231 to clamp the first and second sides of the rigid battery cell 700. This allows the third drive unit 5230 to control the first clamping unit 5231 to lift the rigid battery cell 700, moving it away from the material carrier tray 200. This ensures sufficient space around the rigid battery cell 700, preventing interference from adjacent rigid battery cells 700 during the adhesive application process, and facilitating subsequent adhesive application steps.

[0127] Step S1020: Control the first tape release unit to release the first tape, and control the first drive unit to control the first adsorption unit to adsorb the first tape. When the first tape reaches the preset length, control the first tape release unit to stop releasing the first tape, and control the first tape cutting unit to cut the first tape.

[0128] It is worth noting that the tape is in the form of a film roll, which includes a first film roll. The first film roll is installed in the first tape release unit 5260. The tape in the first film roll is released by controlling the first tape release unit 5260. In one embodiment, a first length detection unit (not shown in the figure) is also provided. The first length detection unit is located on one side of the first tape release unit 5260. The first length detection unit is used to detect the length of the first tape. When the first tape reaches a preset length, the first tape release unit 5260 is controlled to stop releasing the first tape, and the first tape cutting unit 5280 is controlled to cut the first tape.

[0129] Step S1030: Control the first driving unit to control the first adsorption unit to attach the first tape to the third side of the rigid battery cell.

[0130] Step S1040: Control the second tape release unit to release the second tape, and control the second drive unit to control the second adsorption unit to adsorb the second tape. When the second tape reaches the preset length, control the second tape release unit to stop releasing the second tape, and control the second tape cutting unit to cut the second tape.

[0131] It is worth noting that the film roll includes a second film roll, which is installed in the second tape release unit 5270. The tape in the second film roll is released by controlling the second tape release unit 5270. In one embodiment, a second length detection unit (not shown in the figure) is also provided. The second length detection unit is located on one side of the second tape release unit 5270 and is used to detect the length of the second tape. When the second tape reaches a preset length, the second tape release unit 5270 is controlled to stop releasing the second tape, and the second tape cutting unit 5290 is controlled to cut the second tape.

[0132] Step S1050: Control the second driving unit to control the second adsorption unit to attach the second adhesive tape to the fourth side of the rigid battery cell; wherein the third side of the rigid battery cell is opposite to the fourth side.

[0133] It is worth noting that the first adsorption unit 5240 and the second adsorption unit 5250 are positioned opposite each other. The distance between the first adsorption unit 5240 and the third side of the rigid battery cell 700 is smaller than the distance between the second adsorption unit 5250 and the third side of the rigid battery cell 700. However, the distance between the first adsorption unit 5240 and the fourth side of the rigid battery cell 700 is greater than the distance between the second adsorption unit 5250 and the fourth side of the rigid battery cell 700. Therefore, by using the first adsorption unit 5240 to attach the first tape to the third side of the rigid battery cell 700 and controlling the second adsorption unit 5250 to attach the second tape to the fourth side of the rigid battery cell 700, the bonding efficiency can be improved.

[0134] Step S1060: Control the first driving unit to control the first adsorption unit to move away from the hard battery cell, and control the second driving unit to control the second adsorption unit to move away from the hard battery cell.

[0135] In step S1070, the third drive unit controls the first clamping unit to drive the rigid battery cell down and causes the first clamping unit to release the rigid battery cell so as to place the rigid battery cell on the material carrier tray.

[0136] In this embodiment, the adhesive application process for the rigid battery cell 700 is achieved through steps S1010 to S1070. During adhesive application, the third drive unit 5230 is first controlled to control the first clamping unit 5231 to lift the rigid battery cell 700. After adhesive application is completed, the third drive unit 5230 is controlled to control the first clamping unit 5231 to lift the rigid battery cell 700 and release the rigid battery cell 700 so that the rigid battery cell 700 is placed on the material carrier tray 200. In this way, while completing the adhesive application process, the position of the rigid battery cell 700 remains unchanged from its position before adhesive application. Moreover, the rigid battery cell 700 does not rotate or perform any other actions during the adhesive application process, which ensures that the positions of the positive and negative electrodes in the rigid battery cell 700 remain unchanged.

[0137] In one embodiment, reference is made to Figure 7 The adhesive application module 500 in this embodiment further includes an adhesive application detection component 530, which is located between the adhesive application component 520 and the film removal component 540. (Refer to...) Figure 11 , Figure 11 This is a simplified structural diagram of the adhesive application detection component 530 according to an embodiment of this application. The adhesive application detection component 530 includes a second vision unit 532, a second robotic arm unit 531, a defective product placement stage 533, and a good product placement stage 534. Multiple rigid battery cells 700 that have undergone pre-applied adhesive treatment and passed the adhesive application process are placed on the good product placement stage 534. (Refer to...) Figure 12 , Figure 12 This is a schematic diagram of a sub-process of a cell assembly method according to another embodiment of this application. Before step S840, the method of this embodiment further includes the following steps:

[0138] Step S1210: Control the transport module to transport the material carrier tray to one side of the adhesive detection component;

[0139] Step S1220: Control the second vision unit to acquire a third image of the rigid battery cell on the material carrier plate;

[0140] Step S1230: The rigid battery cell is subjected to adhesive adhesion detection processing through the third image. If the adhesive adhesion of the rigid battery cell is found to be unqualified, the unqualified rigid battery cell is determined, and the second vision unit is controlled to acquire the fourth image of the unqualified rigid battery cell.

[0141] It is worth noting that unqualified cells refer to rigid cells 700 that fail the adhesive bonding test. In step S1230, if all rigid cells 700 on the material carrier tray 200 are found to have passed the adhesive bonding test, then steps S1240 to S1260 do not need to be executed, and step S840 can be executed directly.

[0142] Step S1240: Obtain the non-conforming location information of the non-conforming hard battery cells based on the fourth image. The non-conforming location information includes the sorting information of the non-conforming hard battery cells and the position information of the first and second identification parts of the non-conforming hard battery cells.

[0143] Step S1250: Control the second robotic arm unit to transport the non-conforming hard battery cells to the defective product placement table;

[0144] In step S1260, the second robotic arm unit is controlled to obtain qualified hard battery cells from the good product placement table, and based on the unqualified position information of the unqualified hard battery cells, the qualified hard battery cells are transported to the material carrier tray so that the qualified position information of the qualified hard battery cells is the same as the unqualified position information of the unqualified hard battery cells.

[0145] It is worth noting that a qualified rigid battery cell 700 refers to a rigid battery cell 700 placed on the good product placement table 534 and having passed the adhesive application test. The qualified position information includes the sorting information of the qualified rigid battery cells 700 and the position information of the first marking part 710 and the second marking part 720 of the qualified rigid battery cells 700; the qualified position information can be obtained through the second vision unit 532.

[0146] In related technologies, during the battery cell assembly process, if a battery cell is found to have substandard adhesive bonding, the production process needs to be stopped, and the entire material carrier 200 is treated as waste, resulting in low production efficiency. However, in the embodiment of this application, through steps S1210 to S1260, if a substandard hard battery cell 700 is detected to have substandard adhesive bonding, a qualified hard battery cell 700 is used to replace the substandard one. Thus, the production process can continue without stopping, improving production efficiency.

[0147] Reference Figure 13 , Figure 13 This is a simplified structural diagram of the film-tearing assembly 540 according to an embodiment of this application. The film-tearing assembly 540 includes a second clamping unit 545, a first film-tearing unit 544, a fourth driving unit 541, and a fifth driving unit 542. The fourth driving unit 541 is connected to the second clamping unit 545 and is used to drive the second clamping unit 545 to move. The fifth driving unit 542 is connected to the first film-tearing unit 544 and is used to drive the first film-tearing unit 544 to move.

[0148] In one embodiment, step S850 includes, but is not limited to, the following steps:

[0149] The fourth drive unit 541 controls the second clamping unit 545 to clamp the Nth rigid battery cell 700, and controls the fourth drive unit 541 to control the second clamping unit 545 to drive the Nth rigid battery cell 700 to rise.

[0150] The fifth drive unit 542 controls the first film-tearing unit 544 to peel off the film of the first adhesive tape on the third side of the Nth rigid battery cell 700; wherein the third side of the Nth rigid battery cell 700 is the side close to the (N-1)th rigid battery cell 700.

[0151] The fourth drive unit 541 controls the second clamping unit 545 to drive the Nth rigid battery cell 700 down, and causes the second clamping unit 545 to release the Nth rigid battery cell 700 so as to place the Nth rigid battery cell 700 on the material carrier tray 200.

[0152] In step S850, when peeling off the film of the adhesive tape, the Nth rigid battery cell 700 is the last rigid battery cell 700. Normally, the last rigid battery cell 700 needs to be in contact with the housing, meaning the fourth side of the Nth rigid battery cell 700 is in contact with the housing. During housing installation, adhesive is applied to the housing, so it is generally not necessary to peel off the film from the side of the rigid battery cell 700 that is in contact with the housing. When peeling off the film of the adhesive tape, only the film of the first adhesive tape on the third side of the Nth rigid battery cell 700 is peeled off, without peeling off the film of the second adhesive tape on the fourth side of the Nth rigid battery cell 700. This simplifies the film-peeling process and improves production efficiency. Furthermore, during the film-tearing process, the fourth drive unit 541 controls the second clamping unit 545 to drive the Nth rigid battery cell 700 upward. After the film is torn, the second clamping unit 545 controls the Nth rigid battery cell 700 to descend and releases the Nth rigid battery cell 700, so as to place the Nth rigid battery cell 700 on the material carrier plate 200, ensuring that the position of the Nth rigid battery cell 700 remains unchanged during the film-tearing process.

[0153] In one embodiment, reference is made to Figure 13 The film-tearing assembly 540 also includes a second film-tearing unit 546 and a sixth driving unit 543; the sixth driving unit 543 is connected to the second film-tearing unit 546 and is used to drive the second film-tearing unit 546 to move.

[0154] In one embodiment, step S850 may further include the following steps:

[0155] The fourth drive unit 541 controls the second clamping unit 545 to clamp the first rigid battery cell 700, and controls the fourth drive unit 541 to control the second clamping unit 545 to drive the first rigid battery cell 700 to rise.

[0156] The sixth drive unit 543 controls the second film-tearing unit 546 to peel off the film of the second adhesive tape on the fourth side of the first rigid battery cell 700; wherein the fourth side of the first rigid battery cell 700 is the side close to the second rigid battery cell 700.

[0157] The fourth drive unit 541 controls the second clamping unit 545 to drive the first rigid battery cell 700 down and causes the second clamping unit 545 to release the first rigid battery cell 700 so as to place the first rigid battery cell 700 on the material carrier tray 200.

[0158] In step S850, when peeling off the film of the adhesive tape, the first rigid battery cell 700 typically needs to be in contact with the housing, that is, the third side of the first rigid battery cell 700 is in contact with the housing. Since adhesive is applied to the housing during installation, it is generally not necessary to peel off the film from the side of the rigid battery cell 700 that is in contact with the housing. When peeling off the film, only the film of the second adhesive tape on the fourth side of the first rigid battery cell 700 is peeled off, without peeling off the film of the first adhesive tape on the third side of the first rigid battery cell 700. This simplifies the film-peeling process and improves production efficiency. Furthermore, during the film-tearing process, the fourth drive unit 541 controls the second clamping unit 545 to drive the first rigid battery cell 700 upward. After the film is torn, the second clamping unit 545 controls the first rigid battery cell 700 to descend and releases the first rigid battery cell 700 to place the first rigid battery cell 700 on the material carrier tray 200, ensuring that the position of the first rigid battery cell 700 remains unchanged during the film-tearing process.

[0159] In one embodiment, step S850 may further include the following steps:

[0160] The fourth drive unit 541 controls the second clamping unit 545 to clamp the j-th rigid battery cell 700, and controls the fourth drive unit 541 to control the second clamping unit 545 to drive the j-th rigid battery cell 700 to rise; where j is a positive integer greater than 1 and less than N.

[0161] The fifth drive unit 542 controls the first film-tearing unit 544 to peel off the film of the first adhesive tape on the third side of the j-th rigid battery cell 700;

[0162] The sixth drive unit 543 controls the second film-tearing unit 546 to peel off the film of the second adhesive tape on the fourth side of the j-th rigid battery cell 700;

[0163] The fourth drive unit 541 controls the second clamping unit 545 to drive the j-th rigid battery cell 700 down, and causes the second clamping unit 545 to release the j-th rigid battery cell 700 so as to place the j-th rigid battery cell 700 on the material carrier tray 200.

[0164] In step S850, when peeling off the film of the adhesive tape, the rigid battery cell 700 located between the first rigid battery cell 700 and the Nth rigid battery cell 700 needs to have not only the film of the first adhesive tape on its third side peeled off, but also the film of the second adhesive tape on its fourth side peeled off. During the film peeling process, the fourth drive unit 541 controls the second clamping unit 545 to drive the j-th rigid battery cell 700 upward. After the film is peeled off, the second clamping unit 545 controls the second clamping unit 545 to drive the j-th rigid battery cell 700 downward and releases the j-th rigid battery cell 700 to place the j-th rigid battery cell 700 on the material carrier tray 200, ensuring that the position of the j-th rigid battery cell 700 remains unchanged during the film peeling process.

[0165] A second aspect of this application provides an electronic device including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the cell assembly method of any one of the first aspects of the embodiment.
