Description

Cleaning method and system Cross-reference to related application This disclosure is based on, and claims priority over, Chinese Patent Application No. 202311321041.6, filed on October 12, 2023, and entitled "CLEANING METHOD AND SYSTEM". Technical Field This disclosure relates to the technical field of batteries, and, in particular, to a cleaning method and system. Background of the technique New energy batteries are being used more and more in everyday life and in industry. For example, new energy vehicles equipped with batteries are widely used. Additionally, batteries are also increasingly used in energy storage and related fields. Currently, for an assembled battery production line, before mounting battery modules in a casing, the production line must first be stopped and a cleaning device used to clean the first battery module and verify the cleaning effect. This means the current cleaning method has to be performed on the production line, which is inconvenient and disrupts normal production. Document CN218223870U describes a plasma first-part cleaning device for battery cells. Compendium of the invention Embodiments of the present disclosure provide a cleaning method as defined in claims 1 to 6, a cleaning system as defined in claims 7 to 14, and a battery production line as defined in claim 15, which can effectively improve operational convenience without affecting normal production and improve production efficiency. Technical solutions for the embodiments of this disclosure are implemented as follows. In one aspect, an embodiment of this disclosure provides a cleaning method applied to a cleaning system. The cleaning system includes a control device, a quick-change platform, and a clamping jaw device. The method includes: determine, by the control device, whether there is a target tool on the quick-swap platform based on target first-item information when the target first-item information is received, where the target first-item information represents drawing information of a first-item battery module; and the target tool is a tool configured to be cleared in place of the first-item battery module; and control, by the control device, the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick exchange platform. In this embodiment, the cleaning system includes the control device, the quick-change platform, and the clamping jaw device. When the cleaning system cleans battery modules, the control device in the cleaning system can determine, based on the drawing information of the first-item battery module to be cleaned, whether there is a tool configured to be cleaned instead of the first-item battery module—that is, the target tool—on the quick-change platform. The control device then controls the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick-change platform.Outside of a production line corresponding to battery modules, the quick exchange platform and clamping jaw device can be used to complete the cleaning of the first-item battery module, thereby effectively improving the convenience of cleaning the first-item battery module and thus improving production efficiency. In some embodiments of this disclosure, the cleaning system includes a plasma cleaning machine, and the clamping jaw device includes a side gripper; and controlling the clamping jaw device to grasp the target tool for cleaning includes: control the clamping jaw device so that it moves to a gripping position corresponding to the target tool; control the side gripper to grasp the target tool based on the gripping position, and control the clamping jaw device to move to a clearing position when the side gripper grasps the target tool; and control the plasma cleaning machine to clean the target tool. In this embodiment, the control device can first control the clamping jaw device to move to the gripping position where the target tool can be gripped, then control the side clamp to grip the target tool in the gripping position, and then move the clamping jaw device that has gripped the target tool to the plasma cleaning machine where plasma cleaning can be performed, so that the plasma cleaning machine starts to be controlled to clean the target tool, thus completing the cleaning of the target tool, which is equivalent to completing the cleaning of the first-item battery module, thus cleaning the first-item battery module using the quick exchange platform and the clamping jaw device, and effectively improving the convenience of cleaning the first-item battery module.In some embodiments of this disclosure, the target tool includes a cleaning plate, and controlling the plasma cleaning machine to clean the target tool includes: Control the plasma cleaning machine for cleaning the cleaning plate. In this embodiment, when the control device controls the plasma cleaning machine to clean the target tool, the plasma cleaning machine is mainly controlled to clean the cleaning plate on the target tool, which can improve the operational convenience of cleaning the first-item battery module. In some embodiments of this disclosure, the quick-swap platform includes a through-beam laser sensor and a reader-writer; and determining whether the target tool is on the quick-swap platform based on battery module plan type information includes: detect, by the control device, whether there is a tool on the quick exchange platform based on the through-beam laser sensor; read a radio frequency identification chip corresponding to the tool by means of the reader-writer when it is determined that the tool is on the rapid exchange platform, to obtain identity information of the tool; and Determine if the tool is the target tool based on the tool's identity information and the target first-item information. In this embodiment, since the through-beam laser sensor is provided on the quick-swap platform, the control device can determine if there is a tool on the quick-swap platform based on detection by the through-beam laser sensor. When it is determined that the tool is on the quick-swap platform, the radio frequency identification chip corresponding to the tool is read by the reader-writer on the quick-swap platform to determine if the tool on the quick-swap platform is the target tool configured to be cleaned instead of the first-item battery module. This accurately detects whether there is a tool on the quick-swap platform and whether the tool matches the first-item battery module, thus improving the automation and intelligence of the cleaning system. In some embodiments of this disclosure, the quick-change platform includes a placement section, and after the control device controls the clamping jaw device to grasp the target tool for cleaning when the target tool is determined to be on the quick-change platform, the method further includes: control, by the control device, the clamping jaw device to place the target tool in the placement section. In this embodiment, each time the control device controls the clamping jaw device to grasp the target tool to complete cleaning, the control device can also control the clamping jaw device to place the target tool in the placement section, thereby improving the automation and intelligence of the cleaning system. In some embodiments of this disclosure, the quick-change platform includes a work section, and after the control device controls the clamping jaw device to position the target tool in the positioning section, the method further includes: control, by the control device, the quick exchange platform to pull the target tool from the placement section to the working section. In this embodiment, the quick-change platform also includes the working section in addition to the placement section, so that the control device can also control the quick-change platform to pull the target tool placed in the placement section to the working section, to facilitate gripping for the next time and cleaning, thereby improving the automation and intelligence of the cleaning system. In some embodiments of this disclosure, the method also includes: to control, by the control device, the quick-change platform to move out when an operating instruction to move out of the quick-change platform is received; or The control device commands the quick-change platform to move backward when it receives an operating instruction to move backward. In this embodiment, when the control device receives an operating instruction to move the quick-change platform outward, the quick-change platform can be controlled to move outward, or when the control device receives an operating instruction to move the quick-change platform backward, the quick-change platform can be controlled to move backward, thus completing the operation of moving the quick-change platform outward or backward and improving the automation and intelligence of the cleaning system. In a second aspect, an embodiment of the present disclosure provides a cleaning system. The cleaning system includes a quick-change platform, a clamping jaw device, a plasma cleaning machine, and a control device, where The quick-change platform and clamping jaw device are connected to the control device; the control device is configured to control, when it is determined that there is a target tool on the quick-change platform based on target first-item information, the clamping jaw device to grab and move the target tool to the plasma cleaning machine for cleaning; and The quick exchange platform is configured to hold the target tool. In this embodiment, the target tool can be placed on the quick-change platform. When the control device receives the target first-item information and determines that the target tool is on the quick-change platform, the clamping jaw device can be controlled to grasp the target tool and move it to the plasma cleaning machine for cleaning. This allows the cleaning operation to be completed using the quick-change platform and the target tool without cleaning the first-item battery module on a battery production line, thereby effectively improving the convenience of cleaning the first-item battery module and further enhancing production efficiency.

Detailed description of achievements The technical solutions in the embodiments of this disclosure are clearly and completely described below with reference to the accompanying drawings. It may be understood that the specific embodiments described herein are intended only to explain the related application, but not to limit it. It should also be noted that, for ease of description, only parts related to the related application are shown in the accompanying drawings. New energy batteries are increasingly used in everyday life and industry. They are not only used in energy storage systems such as hydroelectric, thermal, wind, and solar power plants, but are also widely used in electric vehicle applications such as electric bicycles, electric motorcycles, electric cars, aerospace, and more. In the realizations of this disclosure, the battery may be a battery cell. A battery cell refers to a basic unit capable of converting chemical energy into electrical energy and can be used to manufacture a battery module or battery pack to supply power to a power-consuming device. A battery cell may also be a secondary battery. A secondary battery refers to a battery cell in which active materials can be activated by charging for reuse after the battery cell has been discharged. The battery cell may be a lithium-ion battery, a sodium-ion battery, a lithium-sodium-ion battery, a lithium-metal battery, a sodium-metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid storage battery, etc., which is not limited in the achievements of this disclosure. In the embodiments of this disclosure, the battery may also be a single physical module comprising one or more battery cells to provide increased voltage and capacity. When a plurality of battery cells is provided, the cells are connected in series, in parallel, or in a series-parallel configuration by means of a bus bar component. The battery may be a battery module or a battery pack. During the assembly of batteries into a battery casing, before the battery modules are assembled into the casing, a cleaning device is used to clean each battery module. The battery modules are then assembled into the casing to ensure the final batteries meet assembly requirements. The cleaning effect is verified by an ink test on the first cleaned battery module at the beginning of each shift. A specific operating procedure for cleaning a first-item battery module is as follows: (1) Cleaning of the first battery module of a current shift is completed; (2) a robot carries the module to a detection position; (3) a worker enters the device to perform a cleaning effect test on the battery module; (4) after the test is completed, a first-article result is entered into a computer and uploaded to a manufacturing execution system (MES) to complete a first-article task; (5) the robot cleans the first battery module again (removing any remaining substances on a surface during the test); (6) the robot assembles the first battery module into the housing for assembled batteries; and (7) The robot continues to grasp the next battery module, clean it, and place it in the housing. It is clear that the current cleaning method must be implemented on a production line. When cleaning the first battery module, the production line must first be suspended. Then, the cleaning device is used to clean the first battery module and verify the cleaning effect, which disrupts the normal production of the assembled batteries. Furthermore, an operator has to enter the device to operate it, which is not only inconvenient but also hazardous. To address the problems with the current cleaning method, the realizations in this disclosure provide a cleaning method and system. The cleaning system includes a control device, a quick-change platform, and a clamping jaw device.The control device can determine if there is a target tool on the quick-change platform based on target first-item information when the target first-item information is received, where the target first-item information represents drawing information of a first-item battery module; and the target tool is a tool configured to be cleaned instead of the first-item battery module; and when it is determined that the target tool is on the quick-change platform, the clamping jaw device is controlled to grip the target tool for cleaning, which can effectively improve the convenience of operation without affecting normal production and improve production efficiency. The technical solutions in the embodiments of this disclosure are described below clearly and completely with reference to the accompanying drawings in the embodiments of this disclosure. An embodiment of the present disclosure provides a cleaning method applied to a cleaning system. FIG. 1 is a first schematic diagram of a compositional structure of a cleaning system according to an embodiment of the present disclosure. As shown in FIG. 1, the cleaning system 0 may include a control device 1, a quick-swap platform 2, and a clamping jaw device 3, and the control device 1 may be connected to the quick-swap platform 2 and the clamping jaw device 3, wherein the control device 1 may be any of a programmable logic controller (PLC), a single-chip microcomputer, an intermediary computer, and a higher-level computer;and is configured to determine if there is a target tool on the quick-swap platform based on target first-item information when the target first-item information is received, where the target first-item information represents drawing information of a first-item battery module; and the target tool is a tool configured to be cleaned instead of the first-item battery module; and the control device controls the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick-swap platform. The quick-swap platform 2 can be configured to hold the tool. The clamping jaw device 3 can be configured to grasp the tool held on the quick-swap platform 2. In the embodiments of this disclosure, FIG. 2 is a first schematic diagram of a process for implementing a cleaning method according to one embodiment of this disclosure. As shown in FIG. 2, the method for performing cleaning by a cleaning system may include the following steps. In step 101, a control device determines whether there is a target tool on a quick-change platform based on target first-item information when the target first-item information is received, where the target first-item information represents drawing information of a first-item battery module; and the target tool is a tool configured to be cleaned in place of the first-item battery module. In the embodiments of this disclosure, the control device can first determine whether the target tool is on the quick-swap platform based on battery module plan information when the battery module plan information is received, where the battery module plan information represents the plan information of the first-item battery module to be cleaned; and the target tool is a tool configured to be cleaned in place of the first-item battery module. It should be noted that in the embodiments of this disclosure, when the cleaning system starts first-item cleaning, the control device in the cleaning system can receive the target first-item information by means of a human-machine interaction module, where the human-machine interaction module can be a human-machine interface (HMI). For example, an operator can perform, via the HMI, a selection operation on the first-item battery module that needs to be cleaned, and after receiving selection operation information from the first-item battery module, the HMI sends the target first-item information to the control device, or the control device receives the target first-item information via the HMI. It should be noted that in the realizations of this disclosure, the target tool may be one of multiple tools, and different tools may be used to perform cleaning instead of different first-item battery modules. It should be noted that, in the embodiments of the present disclosure, multiple identical or different tools may be placed on the quick-swap platform, and the control device first has to determine if there is, on the quick-swap platform, a target tool corresponding to the first-item battery module that currently needs to be cleaned, so that a subsequent cleaning operation will be performed only when it is determined that the target tool is on the quick-swap platform. In step 102, the control device controls the clamping jaw device to grab the target tool for cleaning when it is determined that the target tool is on the quick exchange platform. In the embodiments of this disclosure, after determining whether there is a target tool on the quick-change platform based on target first-item information when the target first-item information is received, the control device can control the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick-change platform. In some embodiments of this disclosure, if the control device determines that there is no target tool on the quick-change platform, alarm processing can be performed by means of the human-machine interaction module; for example, alarm processing can be performed by displaying alarm warning information to alert the operator that there is no target tool on the quick-change platform. In some embodiments of this disclosure, the cleaning system also includes a plasma cleaning machine. In some embodiments of this disclosure, the clamping jaw device includes a side clamp. In some embodiments of this disclosure, when the clamping jaw device is controlled to grip the target tool for cleaning, the control device can control the clamping jaw device to move to a gripping position corresponding to the target tool; control the side gripper to grip the target tool based on the gripping position; control the clamping jaw device to move to a cleaning position when the side gripper grips the target tool; and control the plasma cleaning machine to clean the target tool.It should be noted that in the embodiments of the present disclosure, when the clamping jaw device is controlled to move to the gripping position corresponding to the target tool, the clamping jaw device may first be controlled to move to a position above the target tool, and then the clamping jaw device may be controlled to move toward the target tool in a vertical direction perpendicular to a ground, which is equivalent to movement on a Z axis in a three-dimensional coordinate system until the clamping jaw device moves to the gripping position. It may be understood that in the embodiments of this disclosure, the gripping position may be a position above the target tool, and when the clamping jaw device moves to the gripping position, the control device may grip the target tool by controlling the side clamp on the clamping jaw device to perform a gripping action. It can be understood that in the embodiments of this disclosure, the cleaning position represents a position in which the cleaning of the target tool can be completed by the plasma cleaning machine. In some embodiments of the present disclosure, after the clamping jaw device is controlled to move into the cleaning position, the operator can splash ink onto the target tool gripped in the side clamp, and then the control device can control the plasma cleaning machine to perform a cleaning operation in response to a cleaning start instruction. For example, the cleaning position might be located diagonally above the plasma cleaning machine. The control device operates the clamping jaw to grip and move the target tool to the cleaning position. Then, after the operator applies ink to the target tool, a start operation can be performed on the plasma cleaning machine. For example, a start button on the plasma cleaning machine can be pressed, or a start operation can be performed on the plasma cleaning machine in the human-machine interface module. The plasma cleaning machine will then send a start cleaning instruction to the control device, which will begin controlling the plasma cleaning machine to perform the cleaning operation on the target tool in response to the start cleaning instruction. It should be noted that in the embodiments of this disclosure, when the control device controls the plasma cleaning machine to clean the target tool, the plasma cleaning machine can be controlled to clean a cleaning plate. It should also be noted that in the embodiments of the present disclosure, the cleaning plate is made of the same material as the first-article battery module. That is, in the embodiments of the present disclosure, since the cleaning plate on the target tool is made of the same material as the first-article battery module, when the control device controls the plasma cleaning machine to perform a cleaning operation on the target tool, the cleaning of the target tool can be completed by cleaning only the cleaning plate on the target tool instead of cleaning the entire structure of the target tool. In some embodiments of this disclosure, after the target tool cleaning is completed, a cleaning effect test may also be performed depending on the target tool. In some embodiments of this disclosure, after controlling the clamping jaw device to grip the target tool for cleaning, the control device can control the clamping jaw device to place the target tool back on the quick-change platform to perform the cleaning effect test. In some embodiments of the present disclosure, after the cleaning system control device controls the clamping jaw device to grip the target tool for cleaning, the cleaning system can also perform a cleaning operation on battery modules when the target tool passes the cleaning effect test, wherein the cleaning operation on battery modules includes a cleaning operation on the first-item battery module and battery modules other than the first-item battery module. In some embodiments of the present disclosure, after cleaning the battery modules, battery housing assembly can be performed based on the cleaned battery modules; that is, a process is performed to allow the modules to enter the housing. For example, when performing the cleaning effect test, the operator can flip the target tool over to allow the cleaning plate on the target tool to face upwards, and then perform the cleaning effect test on one surface of the cleaning plate. In some embodiments of this disclosure, when the operator performs the cleaning effect test on the surface of the cleaning plate, dyne ink may be applied to the surface of the cleaning plate, and a dyne value of the cleaning plate surface is then obtained. When the dyne value of the cleaning plate surface falls within a predetermined range of values, it can be determined that the cleaning effect test has been passed. In the realizations of this disclosure, since the cleaning effect test is performed outside of a production line apparatus, the production line apparatus can continue producing while the cleaning effect test is being performed, thereby improving production efficiency. It should be noted that in the embodiments of this disclosure, the cleaning method implemented using the quick-change platform, clamping jaw device, and tool does not affect the production line for assembled batteries. Therefore, it is not necessary to suspend the production line, and a first-item cleaning process can be performed simultaneously with another assembly, such as a battery housing for assembled batteries, without impacting production capacity. Furthermore, compared to current related technologies, the cleaning method according to this disclosure allows for more convenient cleaning of battery modules in a manipulator, reduces worker involvement, has a higher degree of automation, and effectively improves safety performance. In some embodiments of this disclosure, the rapid exchange platform may include a through-beam laser sensor and a reader-writer. In some embodiments of this disclosure, when it is determined whether the target tool is on the quick-swap platform based on the battery module's planar information, the control device can detect whether there is a tool on the quick-swap platform based on the through-beam laser sensor; a radio frequency identification (RFID) chip corresponding to the tool is read by the reader-writer when it is determined that the tool is on the quick-swap platform, to obtain the tool's identity information; and whether the tool is the target tool is determined based on the tool's identity information and the battery module's planar information. In some embodiments of this disclosure, the quick-swap platform may further include a tool holder, the tool is placed in the tool holder, and the radio frequency identification chip is located on a lower portion of the tool holder. It should be noted that in the embodiments of the present disclosure, different tools can be supported by means of different tool holders; that is, a tool is placed on the quick-change platform according to a tool holder corresponding to the tool, a lower part of this corresponding tool holder is provided with a radio frequency identification chip, and identity information of the tool placed in this tool holder can be determined by reading the radio frequency identification chip. It should also be noted that in the embodiments of this disclosure, the radio frequency identification chip may store the tool's identity information; for example, the tool's identity information may be planar information, and the planar information may include relevant information from a battery module and product corresponding to this tool. In some embodiments of this disclosure, the rapid exchange platform also includes a placement section and a work section. In some embodiments of this disclosure, after controlling the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick-change platform, the control device can control the clamping jaw device to place the target tool into the placement section. In some embodiments of the present disclosure, after controlling the clamping jaw device to place the target tool in the placement section, the control device can control the quick-change platform to pull the target tool located in the placement section to the working section. In some embodiments of this disclosure, the control device may further control the quick-change platform to move out when an operating instruction to move out of the quick-change platform is received; or control the quick-change platform to move backward when an operating instruction to move backward from the quick-change platform is received. For example, the move-out or move-back operation of the quick-change platform can be applied to a usage scenario where a tool needs to be placed or replaced on the quick-change platform, such as a scenario where there is no tool on the quick-change platform and the operator needs to place a tool on the quick-change platform for subsequent use. As shown in FIG. 3, the method may include the following steps. In stage 301, an operator presses a move-out button corresponding to a quick-change platform. In this embodiment, when a tool is placed on the quick-change platform, the operator can press the move-out button corresponding to the quick-change platform after preparing the tool, and a control device performs step 302 in response to a move-out operating instruction. At stage 302, the quick exchange platform moves out automatically. In step 303, the operator removes a suction cup positioning plate on the quick exchange platform. In step 304, the operator places the tool and a tool holder together on the suction cup positioning plate. In step 305, the operator pushes back the suction cup positioning plate. In stage 306, the operator presses a back movement button corresponding to the quick exchange platform. In step 307, the quick-change platform is controlled to automatically move backward. For example, as shown in FIG. 4, when a first-item plasma cleaning process is initiated, the method may include the following steps. In stage 201, an operator selects a first-item battery module in a human-machine interaction module. In step 202, a control device determines if there is a target tool on a quick-change platform. In this embodiment, the control device determines whether the target tool is on the quick-change platform. This includes determining if a tool is present on the quick-change platform and whether that tool is the target tool. Step 203 is then executed when the target tool is determined to be present, or step 211 is executed when the target tool is not present. In step 203, the control device controls a clamping jaw device to move to a position above the target tool. In step 204, the clamping jaw device is controlled to move into a gripping position in a Z-axis direction. In stage 205, a side gripper is controlled to grasp the target tool. In step 206, the clamping jaw device is controlled to move back to an origin in the Z-axis direction. In step 207, the clamping jaw device is controlled to move to a cleaning position from the origin. For example, the cleaning position can be a position diagonally above a plasma cleaning machine. In step 208, the operator splashes ink onto the target tool and starts the plasma cleaning machine. In stage 209, the control device controls the plasma cleaning machine to clean the target tool. In step 210, the control device controls the clamping jaw device to place the target tool back into the quick-change platform. In this embodiment, after the target tool is cleaned by the plasma cleaning machine, the first-item plasma cleaning process is completed. In stage 211, alarm processing is performed. In this embodiment, the control device can perform alarm processing to alert the operator that there is no target tool on the current quick-change platform; and the cleaning operation can be continued after the target tool is placed on the quick-change platform. In the embodiments of the present disclosure, on the assembled battery production line, a network structure for assembling battery modules in a housing can be as shown in FIG. 5. The control device 1 can be a PLC, and control device 1 can be connected to a valve terminal 81, a distributed input / output module 82, a human-machine interface module 83, a remote input / output module 84, a servomotor 85, a small PLC 86, and a servo controller 87.Additionally, the control device 1 can be connected to a PC terminal 88 of an MES, and the PC terminal 88 of the MES can be connected to a camera 89 and a video monitoring system 810. The camera 89 can be a charge-coupled device (CCD). In one embodiment of this disclosure, a cleaning method is provided and applied to a cleaning system. The cleaning system includes a control device, a quick-change platform, and a clamping jaw device. The control device determines whether a target tool is present on the quick-change platform based on target first-item information when the target first-item information is received, where the target first-item information represents drawing information of a first-item battery module to be cleaned; and the target tool is a tool configured to be cleaned in place of the first-item battery module; and the control device controls the clamping jaw device to grasp the target tool for cleaning when it is determined that the target tool is on the quick-change platform.Therefore, it can be seen that when the cleaning system cleans the first-item battery module, the control device in the cleaning system can determine, based on the first-item battery module that has to be cleaned, if there is a tool set up to be cleaned instead of the first-item battery module on the quick-change platform, i.e., the target tool, to control the clamping jaw device to grab the target tool for cleaning when it is determined that the target tool is on the quick-change platform.Outside of a production line corresponding to battery modules, the quick exchange platform and clamping jaw device can be used to complete the cleaning of the first-item battery module, thereby effectively improving the convenience of cleaning the first-item battery module and thus improving production efficiency. Based on the above-mentioned embodiment, a cleaning system is provided in another embodiment of the present disclosure. As shown in FIGS. 6, 7, and 9, the cleaning system 0 may include a control device 1, a quick-change platform 2, a clamping jaw device 3, a plasma cleaning machine 4, a power mechanism 5, and a protective frame 6. In the embodiments of the present disclosure, the control device 1 can be connected to the quick-change platform 2 and the clamping jaw device 3, and the control device 1 is configured to control, when it is determined that there is a target tool 7 on the quick-change platform 2 based on target first-item information, the clamping jaw device 3 to grab and move the target tool 7 to the plasma cleaning machine 4 for cleaning; and the quick-change platform 2 is configured to place the target tool 7. In some embodiments of this disclosure, the control device 1 can determine whether the target tool 7 is on the quick-swap platform 2 based on plan-type information from the battery module when the target first-item information is received, where the target first-item information represents plan-type information of a first-item battery module; and the target tool 7 is a tool configured to be cleaned instead of the first-item battery module; and the control device controls the clamping jaw device 3 to grip the target tool 7 for cleaning when it is determined that the target tool 7 is on the quick-swap platform 2.

Here, the arrangement of the clamping parts 712 facilitates the gripping of the base body 71 by the clamping jaw device 3, and at least two clamping parts 712 are evenly distributed so that the clamping jaw device 3 can apply a more uniform force to the target tool 7, thereby reducing the possibility of the target tool 7 tilting. As shown in FIGS. 11, 12, and 14, in some embodiments of this disclosure, the target tool 7 further includes a tool holder 73. The tool holder 73 includes a positioning portion 731 and limiting portions (pin stems 732 as shown in FIG. 14). As shown in FIGS. 7 and 11, the positioning portion 731 is used for positioning on the quick-change platform 2.

In the embodiments of the present disclosure, the tool holder 73 can be placed directly on the moving member 22, or the tool holder 73 is detachably connected to the moving member 22 by means of clamps, a fastener, etc., to facilitate replacement with a different type of target tool 7. In the embodiments of this disclosure, the placement part 731 may be of a block structure, a plate-type structure, a rod-type structure, etc. For example, the placement part 731 is of a plate-type structure, and the thickness direction of the placement part 731 is established in the vertical direction. A lower side surface of the placement part 731 is joined to an upper side surface of the movement member 22, such that the movement member 22 provides stable support for the placement part 731. Here, with the arrangement of the tool holder 73, the cleaning plate 72 can be supported, and one side of the cleaning plate 72 that needs cleaning is suspended, to reduce the possibility of the cleaning plate 72 becoming soiled. As shown in FIGS.12, 13 and 14, in some embodiments of the present disclosure, the limiting part includes a pin stem 732, the base body 71 is provided with a connection hole 713, and the pin stem 732 can be extended into the connection hole 713, so that the pin stem 732 radially limits the base body 71, thereby fixing the cleaning plate 72 to the tool holder 73. In the embodiments of this disclosure, the radial cross-section of the pin stem 732 may be circular, square, triangular, hexagonal, or similar.

The pin stem 732 with a square radial cross-section may be circumferentially limited to restrict its rotation about the base body 71. The radial cross-section of the connecting hole 713 may also be circular, square, triangular, hexagonal, or similar. For example, the radial cross-section of the pin stem 732 is circular, and the radial cross-section of the connecting hole 713 matches the radial cross-section of the pin stem 732, so that when the pin stem 732 is extended into the connecting hole 713, an outer peripheral wall of the pin stem 732 joins an inner peripheral wall of the connecting hole 713. In the embodiments of this disclosure, the center axis of the pin stem 732 can be set in either a horizontal or a vertical direction. To facilitate the connection and separation of the base body 71 and the tool holder 73, the center axis of the pin stem 732 is set in the vertical direction. The base body 71 can then be moved in the vertical direction to connect to or separate from the tool holder 73, and this direction corresponds to a movement direction of the clamping jaw device 3. In the embodiments of this disclosure, the pin stem 732 may be an equal-diameter stem, or the pin stem 732 may be a variable-diameter stem. For example, the pin stem 732 is a variable-diameter stem, and one end of the pin stem 732, far from the seating portion 731, has a gradually reduced radial dimension in a direction away from the seating portion 731, so that a tapered structure is formed at the end of the pin stem 732 far from the seating portion 731, to facilitate extension into the connecting hole 713. Here, with the arrangement of the pin stem 732 and the connection hole 713, the pin stem can be conveniently connected or disconnected from the connection hole, the limit can be achieved in multiple directions, and the base body 71 can be stably fixed to the tool holder 73. As shown in FIGS.11, 12 and 14, in some embodiments of the present disclosure, there are at least two pin stems 732, the two pin stems 732 form a positioning assembly, and the two pin stems 732 in the positioning assembly are distributed along a diagonal of the positioning portion 731.

In some embodiments of the present disclosure, there are two pin stems 732, and the two pin stems 732 are distributed at two vertices of the placement portion 731 along a diagonal of the placement portion 731. Correspondingly, two connection holes 713 are distributed at two vertices of the base body 71 along a diagonal of the base body 71. Here, the arrangement of the at least two pin stems 732 can improve the limiting effect, and the two pin stems 732 in the same positioning assembly are distributed along the diagonal of the positioning part 731, resulting in greater spacing between the two pin stems 732, thereby achieving a better limiting effect and support of the base body 71. As shown in FIGS. 11, 12 and 14, in some embodiments of this disclosure, the tool holder 73 further includes support parts 733. The support parts 733 connect to the placement part 731, the support parts 733 and the limiting parts are located on the same side of the placement part 731, and the support parts 733 abut against the base body 71. In the embodiments of this disclosure, the support part 733 may be of a block structure, a plate-type structure, a column-like structure, etc. For example, the support part 733 is of a column-like structure, and the direction of a central axis of the support part 733 is parallel to the direction of the central axis of the pin stem 732. When the pin stem 732 is extended in the corresponding connecting hole 713, a lower side of the base body 71 abuts an upper end surface of the support part 733, such that the support part 733 raises the base body 71 to prevent contact between the cleaning plate 72 on the base body 71 and the placement part 731. Here, with the arrangement of the support parts 733, the support parts 733 can raise the base body 71 relative to the placement part 731 to avoid contact between the cleaning plate 72 and the placement part 731, and the side of the cleaning plate 72 that needs cleaning is suspended, to reduce the possibility of the cleaning plate 72 getting dirty. As shown in FIGS. 11, 12 and 14, in some embodiments of the present disclosure, there may be at least two support parts 733, and the at least two support parts 733 and at least two limiting parts are alternately distributed along an edge of the placement part 731. For example, there are two support parts 733 and two pin stems 732; the two support parts 733 are arranged at two vertices of the placement part 731 along one diagonal of the placement part 731, and the two pin stems 732 are arranged at two vertices of the placement part 731 along the other diagonal of the placement part 731.Here, since the support parts 733 and the limiting parts in the placement part 731 are alternately distributed, the placement part 731 supports the base body 71 more evenly, and the limiting parts limit the base body 71 more evenly, so that the base body 71 receives force in a more balanced way, and has a more stable structure. As shown in FIGS. 11, 12 and 14, in some embodiments of the present disclosure, the handles 734 are further arranged at both ends of the placement portion 731 in a length direction of the placement portion, to facilitate movement of the target tool 7 by the operator by means of the handles 734.
