[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure are further elaborated in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limiting the present disclosure. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0034] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0035] The terms "first / second / third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first / second / third" can be interchanged with a specific order or sequence where permitted so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure pertains. The terms used herein are for the purpose of describing the present disclosure only and are not intended to limit the present disclosure.

[0037] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.

[0038] In the embodiments of the present disclosure, the battery may be a battery cell. A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy, and can be used to make a battery module or battery pack, thereby being used to supply power to an electrical device. The battery cell may be a secondary battery, which refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and continue to be used. The battery cell may be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, a lead-acid battery, etc., and the embodiments of the present disclosure are not limited to this.

[0039] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0040] In some embodiments, the battery cell further includes an electrolyte, which acts as a conductor of ions between the positive and negative electrodes. This disclosure does not specifically limit the type of electrolyte, and the electrolyte may be selected based on needs. The electrolyte may be liquid, gel, or solid.

[0041] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0042] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. The prismatic battery cell includes a square-shell battery cell, a blade-shaped battery cell, a polygonal battery, such as a hexagonal battery, etc. There is no special limitation in the present disclosure.

[0043] In some embodiments, the housing includes an end cap and a shell. The shell has an opening, and the end cap closes the opening to form a sealed space for accommodating the electrode assembly, electrolyte, and other substances. The shell may have one or more openings. One or more end caps may also be provided.

[0044] In some embodiments, the housing is provided with at least one electrode terminal, which is electrically connected to the tab. The electrode terminal may be directly connected to the tab or indirectly connected to the tab via an adapter component. The electrode terminal may be provided on the end cap or on the housing.

[0045] In some embodiments, the housing is provided with a pressure relief mechanism for releasing the internal pressure of the battery cell.

[0046] In the embodiments of the present disclosure, the battery may also be a single physical module including one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, in parallel or in hybrid via a busbar.

[0047] An embodiment of the present disclosure provides a method for changing product types on a production line. The production line includes at least one production device corresponding to a process of a product to be produced. As shown in FIG1 , the method includes steps S101 to S103, wherein:

[0048] Step S101: In response to a product change instruction, determine the size information of the product to be produced.

[0049] Here, the method can be executed by a control device, and the product changeover instruction is used to instruct the production equipment in the production line to change its model. The product to be produced is the product to be produced by the production line after the changeover, and the dimensional information of the product to be produced can represent the size of the product. Because the control parameters of the production equipment in the production line are different for different products, and the control parameters are related to the dimensional information of the product to be produced, therefore, before changing the production line, it is necessary to first determine the dimensional information of the product to be produced. In some embodiments, the dimensional information of the product to be produced may include at least one of the following: height information, width information, and thickness information.

[0050] In some embodiments, when the production equipment is the first production process on a production line, the product change instruction may be sent by a production execution system. The production execution system may determine whether to issue a product change instruction based on the number of work orders for the remaining products; the product change instruction may include the size information of the product to be produced. After receiving the product change instruction, the control device may parse the product change instruction to obtain the size information of the product to be produced.

[0051] In some embodiments, when the production equipment is not the first production process on a production line, the product changeover instruction can be represented by the production status of the flexible module of the production equipment of the previous production process or the previous production action. The dimensional information of the product to be produced can be determined based on this production status. In other words, the dimensional information of the product to be produced can be transmitted between production equipment corresponding to different production states, so that different production equipment can obtain the dimensional information of the product to be produced.

[0052] Step S102: Based on the size information of the product to be produced, a target value of a control parameter is correspondingly determined for at least one flexible module in the production equipment.

[0053] Here, the flexible module refers to a module in a production device that can change its own control parameters based on different types of products.

[0054] In an embodiment of the present disclosure, the control device can determine the target value of the control parameter for the flexible module based on the size information of the product to be produced corresponding to the function of the flexible module, wherein the size information of the product to be produced matches the function of the flexible module. For example, when the flexible module is used to detect the layer height of the incoming material of the product to be produced, the size information is the height information of the product to be produced, that is, based on the height information of the product to be produced, the target value of the control parameter is determined for the flexible module used to detect the layer height of the incoming material of the product to be produced; when the flexible module is used to transport the incoming material of the product to be produced, the size information is the width information of the product to be produced, that is, based on the width information of the product to be produced, the target value of the control parameter is determined for the flexible module used to transport the incoming material of the product to be produced.

[0055] In some embodiments, the control device can pre-set a control parameter set, which includes a first mapping relationship between the size information of multiple products and the target values ​​of their corresponding control parameters; after obtaining the size information of the product to be produced, the control device can match the size information of the product to be produced with the multiple first mapping relationships in the control parameter set, and determine the target value of the control parameter for at least one flexible module in the production equipment.

[0056] Step S103: sending the target value corresponding to the control parameter of the at least one flexible module to the controller of the corresponding flexible module to process the incoming material of the product to be produced.

[0057] Here, the processing mode of the incoming materials of the product to be produced can be processing or non-processing. In some embodiments, the non-processing can be testing or handling.

[0058] In the embodiment of the present disclosure, the target value of the control parameter can be sent to the controller of the flexible module, and the controller of the flexible module can control the flexible module to process the incoming materials of the product to be produced based on the target value of the control parameter.

[0059] In the embodiment of the present disclosure, the size information of the product to be produced can be determined through the product changeover instruction, and then based on the size information of the product to be produced, the target value of the control parameter can be correspondingly determined for at least one flexible module in the production equipment; finally, the target value corresponding to the control parameter of at least one flexible module is sent to the controller of the corresponding flexible module to process the incoming material of the product to be produced. In this way, according to the size information of the product to be produced, the target value of the control parameter can be quickly determined for at least one flexible module in the production equipment, so that the controller of the flexible module controls the flexible module to process the incoming material of the product to be produced based on the target value of the control parameter. In this way, the target value of the control parameter of the production equipment on the production line is determined by the size information of the product to be produced, and the changeover efficiency of the production line can be improved.

[0060] In some embodiments, the flexible module includes at least one of the following: a drive module and a detection module; when the flexible module includes a drive module, step S103 may include: the control device sends the target value of the control parameter to the controller of the drive module, wherein, after the drive module reaches the target point, the actuator or detection module connected to the drive module processes the incoming material of the product.

[0061] Here, the drive module can be a module capable of providing force and motion, used to drive an actuator or detection module. The actuator can be a mechanism for securing incoming materials for the product to be produced; illustratively, the actuator can be a clamping plate mounted on a robot's gripper. The robot can be a robot located in various production processes. The detection module can be a module for detecting incoming materials for the product to be produced; illustratively, the detection module can be a detection sensor for detecting the layer height of the incoming materials for the product to be produced.

[0062] In the embodiment of the present disclosure, after the control device sends the target value of the control parameter to the controller of the drive module, the controller can control the drive module to reach the target point based on the target value of the control parameter, so that the actuator or detection module connected to the drive module can process the incoming material of the product.

[0063] In some embodiments, when the flexible module includes a detection module, the control parameters of the detection module include position parameters of the target object detected by the detection module; the above step S103 can be implemented by steps S131 and S132:

[0064] Step S131: The control device sends the target value of the position parameter of the target object to the controller of the detection module.

[0065] Step S132: The detection module detects the target object based on the target value of the position parameter.

[0066] Here, the position parameter of the target object is used to represent the target value assigned by the detection module according to the position parameter to detect the target object. The target object can be an object to be detected in the incoming material of the product to be produced.

[0067] In the embodiment of the present disclosure, when the flexible module is a detection module, the control device can send the target value of the position parameter of the target object to the controller of the detection module, and the controller can control the detection module to detect the target object based on the target value of the position parameter.

[0068] For example, when the incoming material of the product to be produced is a battery cell, the target object may be a battery cell code on the battery cell; the detection module may scan the battery cell code on the battery cell according to the position parameters of the target object.

[0069] The production equipment in step S101 is the production equipment of the first production process on the production line. As shown in FIG2 , step S101 can be implemented through steps S201 and S202:

[0070] Step S201: Receive a product change instruction sent by a production execution system; the product change instruction includes information about the product to be produced, and the product change instruction is sent when the production execution system determines that the number of work orders for the remaining products is 0.

[0071] Here, the first production process is the first process in the production line that processes the incoming materials of the product to be produced. For example, when the incoming materials of the product to be produced are battery cells, the first production process may be a loading process.

[0072] In the disclosed embodiment, before step S201, if the production execution system determines that the number of work orders for the remaining products is zero, a product change instruction is sent to the control device of the production equipment in the first production process, so that the control device receives the product change instruction sent by the production execution system. Here, the number of work orders for the remaining products can indicate that the product currently being produced on the production line has been completely completed and the production process for the next product (i.e., the product to be produced) needs to be carried out, so the product change instruction is sent to perform a cut, pull, and change of the production line.

[0073] In some embodiments, the production execution system may determine whether the number of work orders for the remaining products is 0 based on the number of qualified products currently being produced, the number of unqualified products currently being produced, and the number of required products. If the number of qualified products currently being produced is greater than or equal to the sum of the number of unqualified products previously produced and the number of required products, the determination is made as to whether the number of work orders for the remaining products is 0.

[0074] Step S202: Determine the size information of the product based on the product information to be produced.

[0075] Here, the product information to be produced is used to represent the type of product to be produced, and different types of products correspond to different size information. During implementation, a second mapping relationship exists between each piece of product information to be produced and the corresponding size information. The control device can determine the size information of the product corresponding to the product information to be produced based on this second mapping relationship.

[0076] In the embodiment of the present disclosure, when the production equipment is the production equipment corresponding to the first production process, the product size information can be determined by receiving a product change instruction including product information sent by the production execution system, thereby improving the efficiency of determining the product size information.

[0077] The production equipment in step S101 is a production equipment that is not the first production process on the production line. As shown in FIG3 , step S101 can be implemented through steps S301 to S302:

[0078] Step S301: Obtain the production status of the flexible module in the production equipment corresponding to the previous process or the previous production action.

[0079] Here, the previous process is the preceding process among adjacent processes in production time. For example, if the production process for product a is: process a first, then process b, then process a is the preceding process of process b. The previous production action refers to the preceding production action among adjacent production actions in a non-first production process. For example, if process a includes production action 1 that is performed first and production action 2 that is performed later, then production action 1 is the preceding production action of production action 2.

[0080] Here, the production status of the flexible module in the production equipment can represent information about the product currently being produced by the production equipment. That is, when a production line undergoes a cut, pull, or changeover, the production equipment in that production process needs to update the production status of the flexible module in that production equipment while processing the product being produced. This allows the production equipment in the next process to obtain product information from the production status of the flexible module in the production equipment corresponding to the previous process, allowing for cut, pull, or changeover.

[0081] Step S302: When the product information in the production status of the previous process or the previous production action is different from the product information in the production status of the current production equipment, determine the size information of the product to be produced based on the product information in the production status of the previous process or the previous production action.

[0082] In the embodiment of the present disclosure, after the control device obtains the production status of the flexible module in the production equipment corresponding to the previous process or the previous production action, it needs to determine whether the product information in the production status is the same as the product information in the production status of the current production equipment. If it is determined to be different, the size information of the product to be produced is determined based on the product information in the production status of the previous process or the previous production action.

[0083] In some embodiments, the product information to be produced may be the same as the product information of the production status of the current production equipment. In this case, there is no need to re-determine the size information of the product to be produced, and the size information of the currently produced product can be used as the size information of the product to be produced.

[0084] In the embodiment of the present disclosure, for production equipment that is not the first production process, the size information of the product to be produced can be determined by the production status of the flexible module in the production equipment corresponding to the previous process or the previous production action within the process. In this way, the accuracy of determining the size information of the product to be produced can be improved, because if the size information of the product to be produced is wrong, then the production equipment corresponding to the previous process or the previous production action within the process will be corrected during the process of processing the incoming materials of the product to be produced. Therefore, after the production verification of the production equipment corresponding to the previous process or the previous production action within the process, the accuracy of determining the size information of the product to be produced can be improved.

[0085] In some embodiments, a production line includes a loading device corresponding to the loading process, which includes a layer height detection device. The layer height detection device's drive module includes a first servo drive module that drives a layer height detection sensor along the height direction. As shown in Figure 4, layer height detection device 410 includes a first servo drive module 411 mounted on a bracket 413 and a layer height detection sensor 412. The first servo drive module 411 is used to drive the layer height detection sensor 412 to descend to a target point based on the product's height information, and then perform layer height detection on the incoming product.

[0086] Based on FIG4 , the above step S102 can be implemented through steps S121 to S122:

[0087] Step S121: The control device determines a layer height detection parameter value for the first servo drive module based on the height information of the product to be produced.

[0088] Step S122: The first servo drive module drives the layer height detection sensor to descend to the target point according to the height information of the product, and then performs layer height detection on the incoming product.

[0089] In the embodiment of the present disclosure, after obtaining the height information of the product to be produced, the control device can determine the target point based on the difference between the current height information of the first servo drive module and the height information of the product to be produced, and then control the first servo drive module to drive the layer height detection sensor to descend to the target point, and then perform layer height detection on the incoming material of the product.

[0090] In some embodiments, the driving module of the feeding equipment further includes a second servo driving module on the gripper of the feeding robot; the feeding robot may be a four-axis or six-axis robot, as shown in FIG5 , the gripper 420 of the feeding robot includes a first clamping plate 421, a second clamping plate 422, and a second servo driving module 423; wherein the second servo driving module 423 is capable of adjusting the spacing between the first clamping plate 421 and the second clamping plate 422, so that the first clamping member (not shown) of the first clamping plate 421 and the second clamping member (not shown) of the second clamping plate 422 are respectively against opposite sides of the width direction of the product. Based on FIG5 , the above S102 can be implemented through steps S123 to S124:

[0091] Step S123: The control device determines a loading positioning parameter value for the second servo drive module based on the width information of the product to be produced.

[0092] Step S124: The second servo drive module drives the two clamping plates on the gripper to move so that the distance between the two clamping plates is adjusted to match the width information of the product.

[0093] Here, the two clamping plates on the gripper of the loading robot are the first clamping plate and the second clamping plate mentioned above.

[0094] In the embodiment of the present disclosure, the loading positioning parameter value corresponds to the width information; the second servo drive module can drive the two clamps on the gripper to move based on the loading positioning parameter value, so that the distance between the two clamps is adjusted to match the width information of the product, thereby enabling the gripper of the loading robot to grab the incoming materials of the product to be produced.

[0095] In some embodiments, the loading equipment further includes a loading turntable; the loading robot is used to grab incoming materials of the products to be produced and place them on the loading turntable.

[0096] In some embodiments, the above method may further include step S125:

[0097] Step S125: The control device updates the production status of the gripper of the loading robot to the product information of the product.

[0098] In the disclosed embodiment, while or after determining the loading positioning parameter value for the second servo drive module on the gripper based on the width information of the product to be produced, the production status of the gripper of the loading robot can be updated. In this way, the loading turntable, which is the next production action of the loading robot, can obtain the product information of the product based on the production status of the gripper of the loading robot. Therefore, for the loading turntable, step S101 can also be implemented through steps S111 to S112:

[0099] Step S111: The control device obtains the production status of the gripper of the loading robot.

[0100] Step S112: When the product information in the production status of the gripper is different from the product information in the production status of the loading turntable, the control device determines the size information of the product to be produced based on the product information in the production status of the gripper.

[0101] In the disclosed embodiment, the loading robot is the device corresponding to the previous production action of the loading turntable; therefore, the production status of the loading robot's gripper can be transmitted to the loading turntable. This eliminates the need to send the loading turntable information about the product to be produced through the production execution system, improving the efficiency of the loading turntable in determining the product information to be produced.

[0102] In some embodiments, the driving module of the loading equipment also includes a fifth servo drive module on the loading turntable. Please refer to Figure 6 for a schematic diagram of the equipment structure of the loading turntable. As shown in Figure 6, the loading turntable 51 includes a frame body 510, and at least one support frame 513 (two support frames 513 are shown in Figure 6) provided on the frame body 510, as well as a fifth servo drive module (not shown) and a centering plate 511 provided on each support frame. Among them, the centering plate 511 is used to shape a plurality of battery cells 512 (i.e., the incoming materials of the products to be produced) and then stack them; the fifth servo drive module is used to drive the two centering plates 511 on the loading turntable to move so that the distance between the two centering plates 511 is adjusted to match the width information of the product. Based on Figure 6, the above-mentioned step S102 can be implemented by step S126:

[0103] Step S126: The control device determines a feeding centering parameter value for the fifth servo drive module based on the width information of the product to be produced.

[0104] Here, the fifth servo drive module is used to drive the two centering plates on the loading turntable to move, so that the distance between the two centering plates is adjusted to match the width information of the product, so that the center lines corresponding to the incoming materials of multiple products are in a straight line, thereby realizing the centering processing of the incoming materials of multiple products.

[0105] In the embodiment of the present disclosure, after the gripper of the loading robot grabs the incoming materials of the products to be produced and places them on the loading turntable, the fifth servo drive module can drive the two centering clamps on the loading turntable to move based on the loading centering parameter value, thereby realizing the centering processing of the incoming materials of the products to be produced.

[0106] In some embodiments, the driving module of the loading equipment further includes a sixth servo driving module on the loading turntable; the sixth servo driving module is used to push the incoming material of the product in the thickness direction of the product to eliminate the gaps between multiple incoming materials.

[0107] In some embodiments, the driving module of the loading equipment also includes a seventh servo drive module on the gripper of the material picking robot. The material picking robot can be a four-axis or six-axis robot. As shown in Figure 7, the gripper 61 of the material picking robot includes a third clamping plate 611, a fourth clamping plate 612 and a seventh servo drive module (not shown); wherein, the battery cell 512 is located between the third clamping plate 611 and the fourth clamping plate 612; the seventh servo drive module is used to drive the third clamping plate 611 and the fourth clamping plate 612 on the gripper 61 of the material picking robot to move, so that the distance between the third clamping plate 611 and the fourth clamping plate 612 on the gripper of the material picking robot is adjusted to match the width information of the product. The above step S102 can be implemented by step S127:

[0108] Step S127: The control device determines a material picking positioning parameter value for the seventh servo drive module based on the width information of the product to be produced.

[0109] Here, the seventh servo drive module is used to drive the two clamping plates on the gripper of the retrieving robot to move so that the distance between the two clamping plates on the gripper of the retrieving robot is adjusted to match the width information of the product. The two clamping plates on the gripper of the retrieving robot are the third clamping plate and the fourth clamping plate.

[0110] In the disclosed embodiment, the material picking positioning parameter value corresponds to the width information; the seventh servo drive module can drive the two clamps on the gripper of the material picking robot to move based on the material picking positioning parameter value, so that the distance between the two clamps on the gripper of the material picking robot is adjusted to match the width information of the product, thereby enabling the gripper of the material picking robot to grab the incoming materials of the product to be produced.

[0111] In some embodiments, while determining the material picking positioning parameter value for the seventh servo drive module, the production status of the material picking robot can be updated to the product information of the product.

[0112] In some embodiments, when the product to be produced is a module and the incoming material is a battery cell, the loading equipment further includes a first battery cell tray; the above-mentioned material-picking robot is used to grab the battery cells of the module into the first battery cell tray.

[0113] In some embodiments, after step S127, the method further includes steps S128 to S129:

[0114] Step S128: Obtain the production status of the material-retrieving robot.

[0115] Step S129: Write the product information in the production status of the picking robot into the identification code of the first battery cell tray.

[0116] In the embodiment of the present disclosure, by writing the product information in the production status of the material picking robot into the identification code of the first battery cell pallet, the product information to be produced can be transferred to the first battery cell pallet, so that the equipment for the next production action of the first battery cell pallet can obtain the product information to be produced based on the identification code of the first battery cell pallet.

[0117] In some embodiments, the identification code of the first battery cell tray may be a Radio Frequency Identification (RFID) code.

[0118] In some embodiments, the detection module of the feeding equipment further includes a first code scanning detection module; the target object is a battery cell code; the above step S102 can also be implemented through steps S130 to S131:

[0119] Step S130: The control device determines a target value of a position parameter of a cell code for the first code scanning detection module based on the size information of the product to be produced;

[0120] Step S131 : The first code scanning detection module scans the cell code on the incoming material of the product to be produced based on the target value of the position parameter of the cell code.

[0121] In the disclosed embodiment, the cell code is located in different positions on different types of products, so it is necessary to determine a target value for the cell code position parameter based on the size information of the product to be produced. The target value for the cell code position parameter is used to represent the position information of the cell code on the incoming material of the product to be produced.

[0122] In the disclosed embodiment, the control device first obtains image information of the incoming material of the product to be produced through the first barcode scanning detection module, and then the control device determines the position information of the battery code in the image information based on the target value of the position parameter of the battery code; finally, the first barcode scanning detection module scans the battery code based on the position information of the battery code in the image information; the control device writes the content information of the battery code into the identification code of the first battery cell tray.

[0123] In some embodiments, the next step of the loading process includes a gluing process; the production line includes a gluing device corresponding to the gluing process; as shown in FIG8 , step S101 can be implemented through steps S801 to S802:

[0124] Step S801: The control device scans the identification code of the first battery cell tray to obtain product information of the products in the first battery cell tray.

[0125] Step S802: When the product information of the product in the first battery cell tray is different from the product information in the production status of the gluing device, the control device determines the size information of the product to be produced based on the product information of the product in the first battery cell tray.

[0126] In the disclosed embodiment, because the gluing process precedes the loading process, the dimensions of the product to be produced can be determined based on the product information in the gluing process's production status for gluing equipment that is not part of the first production process. The first cell tray, however, is the final production step in the loading process, so the dimensions of the product to be produced can be determined based on the product information scanned from the first cell tray's identification code.

[0127] In some embodiments, the flexible module in the gluing device includes a visual inspection module and a correction drive module; wherein, the correction drive module can be a flexible module in the film correction mechanism in the gluing device, and the correction drive module can include a first correction drive module and a second correction drive module. As shown in Figure 9, the film correction mechanism 81 includes a substrate 810, and at least one first correction drive module 811 (Figure 9 shows four groups of first correction drive modules) and a second correction drive module 812 arranged on the substrate 810; wherein, the first correction drive module 811 is used to adjust the storage space for placing the film based on the size information of the product. After placing part of the film into the storage space of the first correction drive module 811, the second correction drive module 812 can push all the films into the storage space of the first correction drive module 811 at one time, thereby achieving position correction of the film to be applied.

[0128] In the embodiment of the present disclosure, step S102 can be implemented through steps S803 to S804:

[0129] Step S803: The control device determines target values ​​of film positioning parameters for the correction drive module and film position parameters for the visual inspection module based on the size information of the product to be produced.

[0130] Step S804: the correction drive module performs position correction on the film to be attached based on the target value of the film positioning parameter.

[0131] Here, the film positioning parameter is used to correct the position of the film.

[0132] In the actual application process, the film is stored in the silo, and the size of the film in each silo corresponds to the size information of the product to be produced. Therefore, before obtaining the film, it is necessary to first read the product information to be produced from the identification code of the first battery cell tray, and then obtain the film from the silo corresponding to the product information to be produced. Because the postures of the multiple films stored in the silo may be different, if the film is directly attached to the side of the incoming material of the product after being obtained from the silo, the glue-applying positions corresponding to the incoming materials of different products will be different. Therefore, in the embodiment of the present disclosure, the correction drive module can perform position correction on the film to be attached based on the target value of the film positioning parameter corresponding to the size information of the product.

[0133] In some embodiments, after the position of the film to be attached is corrected, the method further includes steps S805 to S806:

[0134] Step S805: The control device determines the gluing position information of the product based on the product information of the product, and controls the gluing mechanism to stick the film to the side of the product;

[0135] Step S806: The visual inspection module detects the position of the film on the product based on the target value of the film position parameter.

[0136] Here, the target value of the film position parameter is used to characterize the theoretical position of the film on the product; in the embodiment of the present disclosure, after controlling the gluing mechanism to stick the film to the side of the product based on the gluing position information corresponding to the product information of the product, the visual inspection module can detect the position of the film on the product based on the target value of the film position parameter to verify whether the actual position of the film matches the target value of the film position parameter.

[0137] In some embodiments, the side of the product may be a side with a smaller area among the multiple sides of the product.

[0138] In some embodiments, the above-mentioned gluing equipment includes at least one of the following: a small-surface gluing equipment and a large-surface gluing equipment; the film correction parameters include at least one of the following: a small-surface film correction parameter and a large-surface film correction parameter; the film position parameters include at least one of the following: a small-surface film position parameter and a large-surface film position parameter.

The eighth servo drive module drives the fifth clamping plate 911 and the sixth clamping plate 912 on the gripper of the group robot to move, so that the distance between the fifth clamping plate 911 and the sixth clamping plate 912 on the gripper 91 of the group robot is adjusted to match the width information of the product, and then the product can be grasped in the width direction of the product. In the embodiment of the present disclosure, the above-mentioned step S801 can be implemented by step S311:

[0141] Step S311: The control device scans the identification code of the first battery cell tray to obtain product information of the products in the first battery cell tray.

[0142] Correspondingly, step S802 can be implemented through step S321:

[0143] Step S321: When the product information of the product in the first battery cell tray is different from the product information in the production state of the group robot, determine the size information of the product to be produced based on the product information of the product in the first battery cell tray.

[0144] Correspondingly, the above step S102 can be implemented through steps S132 to S133:

[0145] Step S132: Based on the size information of the product to be produced, determine the target value of the control parameter for the eighth servo drive module on the gripper of the group robot.

[0146] Step S133: The eighth servo drive module drives the two clamps on the gripper of the group robot to move, so that the distance between the two clamps on the gripper of the group robot is adjusted to match the width information of the product.

[0147] Here, the two clamping plates on the gripper of the group robot are the fifth clamping plate and the sixth clamping plate mentioned above.

[0148] In some embodiments, the method may further include: updating the production status of the gripper of the group robot to product information of the product.

[0149] In some embodiments, the glue laminating equipment further includes a small unit grouping table; as shown in FIG11 , the small unit grouping table 100 includes a grouping table frame body 1001, and a loading mechanism 101 of a loading area, a pressing mechanism 102 of a pressing area, a first unloading mechanism 103 of a first unloading area, and a second unloading mechanism 104 of a second unloading area, which are arranged on the grouping table frame body 1001; wherein the loading mechanism 101 includes a first fixing mechanism 105; the pressing mechanism 102 includes a second fixing mechanism 106 and a pressing sub-mechanism 107; the first unloading mechanism 103 includes a third fixing mechanism 108; and the second unloading mechanism 104 includes a fourth fixing mechanism 109;

[0150] The first fixing mechanism 105, the second fixing mechanism 106, the third fixing mechanism 108 and the fourth fixing mechanism 109 all include a ninth servo drive module (not shown) and a clamping jaw; the ninth servo drive module drives the two clamping jaws on the fixing mechanism so that the distance between the two clamping jaws matches the thickness information of the product. The pressurizing sub-mechanism 107 includes a tenth servo drive module and a pressurizing plate; the tenth servo drive module is used to adjust the position of the pressurizing plate. The first fixing mechanism 105, the second fixing mechanism 106, the third fixing mechanism 108 and the fourth fixing mechanism 109 can rotate counterclockwise. For example, after rotating 90° counterclockwise, the first fixing mechanism 105 is located at the pressurizing mechanism 102, the second fixing mechanism 106 is located at the first unloading mechanism 103, the third fixing mechanism 108 is located at the second unloading mechanism 104, and the fourth fixing mechanism 109 is located at the loading mechanism 101.

[0151] In the embodiment of the present disclosure, step S301 may be implemented through step S312:

[0152] Step S312: Obtain the production status of the gripper of the group robot;

[0153] Correspondingly, step S302 can be implemented through step S322:

[0154] Step S322: When the product information in the production status of the group robot's gripper is different from the product information in the production status of the fixed mechanism located in the unloading area, determine the size information of the product to be produced based on the product information in the production status of the group robot's gripper.

[0155] In the embodiment of the present disclosure, the size information of the product to be produced may be thickness information. The fixing mechanism of the blanking area may be, for example, the third fixing mechanism and / or the fourth fixing mechanism in FIG. 11 .

[0156] Correspondingly, the above step S102 can be implemented through steps S134 to S135:

[0157] Step S134 : determining a product fixing parameter value for a ninth servo drive module of a fixing mechanism located in a blanking area based on thickness information of the product to be produced.

[0158] In step S135 , the ninth servo drive module in the blanking area drives the two clamping jaws on the corresponding fixing mechanism so that the distance between the two clamping jaws matches the thickness information of the product.

[0159] In some embodiments, after the ninth servo drive module of the fixing mechanism located in the unloading area controls the distance change of the clamping jaws based on the fixed parameter value of the product, the fixing mechanism can be controlled to rotate to the loading area, and the group robot can place the incoming product between the two clamping jaws; then the fixing mechanism is controlled to rotate to the pressurizing area; based on the size information of the product to be produced obtained from the production status of the fixing mechanism, the pressurizing parameter value is determined for the tenth servo drive module; the tenth servo drive module is used to adjust the position of the pressurizing plate on the pressurizing mechanism based on the pressurizing parameter value; after the product to be produced is pressurized by the pressurizing mechanism, the fixing mechanism located in the pressurizing area can be rotated to the unloading area.

[0160] In some embodiments, the gluing equipment also includes a blanking robot; the size information of the product to be produced can be obtained from the production status of the fixed mechanism located in the blanking area to determine the target value of the control parameter for the eleventh servo drive module on the gripper of the blanking robot; the eleventh servo drive module is used to drive the two clamps on the gripper of the group robot to move, so that the distance between the two clamps on the gripper of the blanking robot is adjusted to match the size information of the product, so that the incoming product can be clamped from the blanking area.

[0161] In some embodiments, the gluing equipment further includes a second battery cell tray; the unloading robot is configured to transfer products from the unloading area to the second battery cell tray. In the disclosed embodiment, information about the product to be produced, obtained from the production status of the unloading robot, can be written into the identification code of the second battery cell tray.

[0162] In some embodiments, the large-surface gluing equipment in the gluing equipment can perform large-surface gluing on the products placed in the second battery cell tray. Here, large-surface gluing refers to gluing the larger side surfaces of the products. The process of this large-surface gluing process can be seen in steps S803 to S806.

[0163] In some embodiments, the next process of the gluing process includes a pre-stacking process; the pre-stacking equipment corresponding to the pre-stacking process includes a pre-stacking robot. During implementation, the pre-stacking robot may be a four-axis or six-axis robot. Among them, the gripper of the pre-stacking robot may include a twelfth servo drive module, a seventh plywood, and an eighth plywood; the twelfth servo drive module is used to drive the seventh plywood and the eighth plywood on the gripper of the pre-stacking robot to move, so that the distance between the seventh plywood and the eighth plywood is adjusted to match the height information of the product. In the embodiment of the present disclosure, the structure of the gripper of the pre-stacking robot can be seen in Figure 10. The difference from the gripper of the group robot shown in Figure 10 is that the gripper of the group robot grabs the product in the width direction of the product, while the gripper of the pre-stacking robot grabs the product in the height direction of the product.

[0164] In some embodiments, the production status of the gripper of the pre-stacking robot may be updated based on the product information in the identification code of the second battery cell tray.

[0167] Step S137 : The twelfth servo drive module drives the two clamping plates on the gripper of the pre-stacking robot to move so that the distance between the two clamping plates is adjusted to match the height information of the product.

[0168] Here, the two clamping plates on the gripper of the pre-stacking robot are the seventh clamping plate and the eighth clamping plate.

[0169] In the disclosed embodiment, the pre-stacking equipment further includes a pre-stacking platform, onto which a pre-stacking robot is configured to grab products. The pre-stacking platform is configured to press at least two incoming products together; the pressing surface is the side of the product with the larger area of ​​film applied.

[0170] The equipment structure of the pre-stacking station can be seen in Figure 12. The pre-stacking station 120 includes a support body 123, a placement platform 124 disposed on the support body 123, two sets of thirteenth servo drive modules 121, and two sets of fourteenth servo drive modules 122 located on the placement platform 124. The thirteenth servo drive module 121 is used to adjust the position of the battery cell pads of the pre-stacking station 120; the fourteenth servo drive module 122 is used to adjust the position of the pre-stacking plates of the pre-stacking station 120. On the left side of Figure 12 is a single-row module 125. Single-row module 125 only requires a single gluing process, that is, gluing on the larger side of the battery cell. The thirteenth servo drive module 121 and the fourteenth servo drive module 122 located on the left side are used to press the larger side surfaces of the two battery cells in the single-row module 125 together. On the right side of Figure 12 is a double-row module 126, which requires two gluing processes, i.e. gluing is performed on both the side with a larger area and the side with a smaller area of ​​the battery cell. The above-mentioned small unit grouping station is used to press the sides with a smaller area of ​​the two battery cells together; the thirteenth servo drive module 121 and the fourteenth servo drive module 122 located on the right side are used to press the sides with a larger area of ​​the four battery cells of the double-row module 126 together.

[0171] Based on FIG12 , the above step S102 can be implemented through steps S138 to S140:

[0172] Step S138: The control device determines the pad position parameters for the thirteenth servo drive module of the pre-stacking platform based on the width information of the product to be produced, and determines the stacking position parameters for the fourteenth servo drive module of the pre-stacking platform based on the thickness information of the product to be produced.

[0173] Step S139: The thirteenth servo drive module adjusts the position of the battery cell pad of the pre-stacking platform based on the pad position parameter.

[0174] In the disclosed embodiment, the thirteenth servo drive module adjusts the position of the battery cell pad of the pre-stacking table based on the pad position parameters corresponding to the width information of the product, so that the incoming materials of at least two products can be placed on the battery cell pad after the position is adjusted.

[0175] Step S140: The fourteenth servo drive module adjusts the position of the pre-stacking plate of the pre-stacking table based on the stacking position parameter.

[0176] In the embodiment of the present disclosure, the fourteenth servo drive module adjusts the position of the pre-stacking plate of the pre-stacking table based on the stacking position parameters corresponding to the thickness information of the product, and the pre-stacking plate after position adjustment can press the incoming materials of at least two products.

[0177] In some embodiments, the next process of the pre-stacking process includes a stacking process; and the stacking equipment corresponding to the stacking process includes a stacking robot. During implementation, the stacking robot may be a four-axis or six-axis robot. Among them, the stacking robot may include a fifteenth servo drive module and a ninth clamping plate; the fifteenth servo drive module is used to drive the two ninth clamping plates on the gripper of the stacking robot to move so that the distance between the two ninth clamping plates is adjusted to match the thickness information of the product. In the embodiment of the present disclosure, the structure of the gripper of the stacking robot can be seen in Figure 10. The difference from the gripper of the group robot shown in Figure 10 is that the gripper of the group robot grabs the product in the width direction of the product, while the gripper of the stacking robot grabs the product in the thickness direction of the product.

[0178] In some embodiments, the production status of the gripper of the stacking robot can be updated based on the production status of the pre-stacking station.

[0179] In some embodiments, the above step S102 can be implemented through steps S141 to S142:

[0180] Step S141: Based on the thickness information of the product to be produced, determine the target value of the control parameter for the fifteenth servo drive module on the gripper of the stacking robot.

[0181] Step S142: The fifteenth servo drive module drives the two clamps on the gripper of the stacking robot to move so that the distance between the two clamps is adjusted to match the thickness information of the product.

[0182] Here, the clamping plate on the gripper of the stacking robot is the ninth clamping plate mentioned above.

[0183] In some embodiments, the stacking device further includes a stacking shaping mechanism, a stacking robot is used to grab the pressed products onto a module tray in the stacking shaping mechanism, and the stacking shaping mechanism is used to stack the products on the module tray.

The paired shapers 4 are configured such that at least one of their actions enables the paired shapers 4 to move closer to or further away from each other along a first direction above the stacking table 2, and the alignment operation is performed by the approaching action of the shapers 4.

[0185] As shown in FIG13 , a reference plate 6 is provided on one end of the base support in the second direction. The reference plate 6 is supported, for example, by a bracket (not shown) secured to the base support. The reference plate 6 can be fixedly positioned slightly above the loading surface of the stacking platform 2 to block workpieces placed on the stacking platform 2. The reference plate 6 can also be configured to move in a third direction, allowing it to be moved slightly above the loading surface of the stacking platform 2 as needed. When the reference plate 6 is required to function as a block, it is positioned in a lower blocking position. When it is no longer required, it can be raised to a third position. When the reference plate 6 is raised to the third position, a passage is formed below the reference plate 6 for transporting workpieces, the workpiece queue 11, or an empty pallet 8. Optionally, the reference plate 6 can also translate in the second direction, allowing the starting position of the workpiece queue 11 to be adjusted based on the length of the workpiece queue 11 to be stacked, among other factors. Movement of the reference plate 6 in the second and third directions can be achieved by an actuator. The lower portion of the frame 3 has a running section (not shown) that cooperates with the base-side slide rails 12 and running rails 13 on the base bracket side.

The first shaper 41 and the second shaper 42 are configured to move toward or away from each other in the first direction, and the second shaper 42 and the third shaper 43 are configured to move toward or away from each other in the first direction. By moving the first shaper 41 and the second shaper 42 toward or away from each other in the first direction, workpieces located between the first shaper 41 and the second shaper 42 can be aligned and stacked. By moving the second shaper 42 and the third shaper 43 toward or away from each other in the first direction, workpieces located between the second shaper 42 and the third shaper 43 can be aligned and stacked. This allows two groups of workpieces to be aligned and stacked simultaneously in an automated manner, effectively improving stacking efficiency. The simple structure and operation effectively reduce production costs. Furthermore, each shaper (such as the first shaper 41 , the second shaper 42 and the third shaper 43 ) has a shaping surface 4 a facing the adjacent shaper, and the shaping surface 4 a is used to come into contact with the workpiece.

[0187] In the disclosed embodiment, the stacking device 140 further includes a push plate 52 and a reference plate 6. The push plate 52 is used to push the workpiece. The push plate 52 is mounted on the base support and is configured to move forward or backward in a second direction intersecting the first direction. The forward movement of the push plate 52 performs the pushing operation. The reference plate 6 is mounted on the base support and is located on the opposite side of the push plate 5 in the second direction to block the workpiece.

[0188] In the disclosed embodiment, the stacking device 140 further includes a conveying system for the tray 8, which is provided on the stacking platform 2. Specifically, the system includes a conveying rail (not shown) provided on the stacking platform 2 and extending along the second direction. Driven by a fourth drive device 9 serving as a power source, the tray 8 can be conveyed along the conveying rail through a passage to the stacking platform 2 and carried by the stacking platform 2. The power of the fourth drive device 9 can be transmitted to the tray 8 in the form of a gear and rack, a sprocket and chain, a double-speed chain, or the like.

[0189] Based on FIG. 13 and FIG. 14 , the above step S102 can be implemented through steps S143 to S144:

[0190] Step S143: The control device determines a target value of a shaping parameter for the third servo drive module based on the thickness information and width information of the product to be produced.

[0191] Step S144 : The third servo drive module adjusts the position of the stacking plate of the stacking shaping mechanism based on the target value of the shaping parameter.

Based on FIG15 , step S102 can be implemented through steps S145 to S146:

[0195] Step S145 : The control device determines a pressurizing position parameter value for the fourth servo drive module based on the height information of the product to be produced.

[0196] Step S146: The fourth servo drive module adjusts the position of the pressurizing plate of the module in the pressurizing device based on the pressurizing position parameter value.

The size information includes height information.

[0199] In some embodiments, the production line also includes a module scanning device corresponding to the pressurization process. As shown in Figure 16, the module scanning device 160 includes a device support frame 163, and a sixteenth servo drive module 161 and a second scanning detection module 162 provided on the device support frame 163 (Figure 16 shows two groups of sixteenth servo drive modules and two groups of second scanning detection modules 162); wherein, the second scanning detection module 162 is used to scan the product according to the target value of the number of scanning modules; the sixteenth servo drive module 161 is used to drive the second scanning detection module to move according to the target value of the movement parameter.
