[0069] Hereinafter, the present disclosure will be described in detail.

[0070] 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.

[0071] With the improvement of battery production technology, automated production lines are now widely used for battery processing, assembly, transportation and testing.

[0072] A battery pack contains a variety of fasteners. For example, there are multiple fasteners between the battery pack casing and the upper cover, as well as between battery modules within the battery pack, or between adjacent battery modules. Currently, automated equipment is often used to tighten the fasteners between the battery pack casing and the upper cover.

[0073] However, in the solutions provided by the related art for fastening the fasteners between the box body and the upper cover of the battery pack, there is a disadvantage that the automated equipment is not flexible enough in fastening the fasteners, and there are many usage restrictions.

[0074] It should be noted that the battery packs in the embodiments of the present disclosure can be used, but are not limited to, in power storage systems, vehicles, ships, aircraft, and other electrical devices. The use of battery packs can provide a higher total energy. Furthermore, the battery packs are formed by placing multiple battery packs in a sealed box, which provides more reliable dust and water resistance. Therefore, they can be used in harsher, humid, and even submerged environments.

[0075] A battery pack can contain multiple battery cells, which can be connected in series, parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections. Multiple battery cells can be directly connected in series, parallel, or in a hybrid configuration. Alternatively, a battery pack can consist of multiple battery cells connected in series, parallel, or in a hybrid configuration to form a battery module, which is then connected in series, parallel, or in a hybrid configuration to form a complete battery. The battery can also include other structures, such as a busbar assembly to electrically connect multiple battery cells.

[0076] In the embodiment of the present disclosure, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0077] The battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present disclosure.

[0078] The electrode assembly consists of 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 is placed between the positive and negative electrodes to prevent short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0079] In some embodiments, the electrode assembly includes tabs that can conduct current from the electrode assembly. The tabs include a positive tab and a negative tab.

[0080] In some embodiments, a battery cell may include an outer shell. The outer shell is used to encapsulate components such as the electrode assembly and electrolyte. The outer shell may be a steel shell, an aluminum shell, a plastic shell (such as polypropylene), a composite metal shell (such as a copper-aluminum composite shell), or an aluminum-plastic film. The outer shell may also include a housing and a cover, with a receiving cavity formed between the housing and the cover. Furthermore, terminals may be disposed on the cover.

[0081] 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.

[0082] Some embodiments of the present disclosure are described in detail below with reference to FIG. 1 to FIG. 16 .

[0083] Specifically, referring to Figures 1, 2 and 11, the battery pack fastening system 1 provided in the embodiment of the present disclosure includes an operating platform 11, a fastening assembly 12, a drive assembly 13 and a control module. Among them, the operating platform 11 includes a lifting mechanism 111 and a tray 114. The tray 114 is placed on the lifting mechanism 111. The tray 114 is provided with a storage portion for placing the battery pack, and an operating space is formed above the operating platform 11. The fastening assembly 12 includes a fastening component 121, a marking component 122 and a camera component 125. The fastening component 121 is used to fasten the fasteners between the box body and the upper cover of the battery pack placed on the storage portion. The marking component 122 is used to mark the fasteners. The camera component 125 is used to obtain images of the fasteners. The fastening assembly 12 is installed at the free end of the drive assembly 13. The drive assembly 13 is used to drive the fastening assembly 12 to move to any position in the operating space. The drive assembly 13 and the camera assembly 125 are both electrically connected to the control module. The control module can provide visual guidance for the movement of the fastening assembly 12 based on the image of the fastener obtained by the camera assembly 125, so that the fastening assembly 12 moves to a position corresponding to the fastener to complete the fastening or marking of the fastener.

[0084] It should be noted that in the embodiment of the present disclosure, the specific structural form of the operating platform 11 is not limited. The operating platform 11 can provide support for the battery pack and can lift the tray 114. There are a variety of structural forms that can achieve the above-mentioned purpose. For example, the above-mentioned operating platform 11 can be set as a table-type workbench, and the tray 114 containing the battery pack can be placed on the desktop of the workbench, so that the battery pack can be easily operated. On this basis, the table-type workbench can be set to have a lifting function. For this purpose, the table-type workbench with a lifting function can also be considered as a lifting mechanism. Specifically, a driving member can be set between the legs of the workbench and the desktop to drive the desktop to lift, thereby driving the tray 114 and the battery pack to lift. In addition, the operating platform 11 can also be set specifically according to the battery pack production line's method of transporting the battery pack. It should be noted that, in the embodiment of the present disclosure, a conveyor belt can be used to transport the battery pack. For this, the operating platform 11 can be set as the above-mentioned table-type workbench; in addition, an automated guided vehicle (AGV) can be used to transport the battery pack. The electromagnetic or optical guiding devices provided on the AGV can be used to guide the movement of the AGV, so that the AGV can move along a specified path. In general, in order to facilitate the transportation of the battery pack, the tray 114 on the operating platform 11 can also be set to be able to move with the AGV, so as to facilitate the transportation of the battery pack between different workstations. For this, referring to Figure 1, the operating platform 11 can be set as a support frame structure that can facilitate the movement of the AGV. It should be noted that, in the embodiment of the present disclosure, the AGV can be referred to as a transport cart.

[0085] In addition, it should be noted that, in the embodiments of the present disclosure, there is no limitation on the accommodation portion provided on the tray 114. Specifically, the accommodation portion can be provided according to the shape of the battery pack. Furthermore, in some embodiments of the present disclosure, the space of the accommodation portion can be set to be adjustable. For example, referring to FIG. 11 , in some embodiments of the present disclosure, a support frame can be provided on the tray 114 to form an accommodation portion for placing the battery pack, and a screw rod can be provided on the tray 114 to adjust the space between the support frames. In this way, the tray 114 can accommodate battery packs of different models and specifications.

[0086] On this basis, an operating space for the battery pack fastening system 1 to operate the battery pack is formed above the operating platform 11. By placing the battery pack in the above-mentioned operating space, the battery pack fastening system 1 can be used to operate the battery pack.

[0087] In addition, it should be noted that in the embodiment of the present disclosure, the specific structural form of the drive assembly 13 is not limited, and the drive assembly 13 is used to drive the fastening assembly 12 to move to any position in the above-mentioned operating space. For example, with reference to Figure 1, a six-axis robot 131 can be used as the drive assembly 13 in the embodiment of the present disclosure. In addition, a vertically extending track can be arranged above the operating platform 11, a manipulator can be arranged on the track, and a drive member can be arranged between the manipulator and the track, and the drive member can be used to drive the manipulator to move forward, backward, left, right, and vertically in the horizontal direction. In this way, the manipulator, the above-mentioned track, and the drive member can also be used to form the drive assembly 13.

[0088] In order to more vividly illustrate the battery pack fastening system 1 provided by the embodiment of the present disclosure, in the following description and the accompanying drawings, the driving assembly 13 is set as a six-axis robot 131 as an example for explanation.

[0089] Further, referring to Figures 1 and 2, the battery pack fastening system 1 provided in the embodiment of the present disclosure also includes a fastening assembly 12. Specifically, the fastening assembly 12 in the embodiment of the present disclosure includes a fastening component 121, a marking component 122 and a camera component 125. The fastening component 121 can apply torque to the fastener that needs to be fastened to fasten the fastener. The marking component 122 can mark the fastener that needs to be marked. The camera component 125 is used to obtain an image at the fastener. Exemplarily, in the embodiment of the present disclosure, an electronic device with a camera function can be used as the camera component 125 in the application embodiment, or a camera can be directly used as the camera component 125 in the embodiment of the present disclosure.

[0090] It is understood that the fasteners in the battery pack may be of different types or sizes. To this end, a fastening head that can be quickly detached may be provided on the fastening assembly 121 to adapt to fasteners of different types or sizes. For example, for a hexagonal head bolt, the fastening head may be provided as a corresponding socket head.

[0091] It should be noted that a driving member may be provided in the fastening assembly 121 so that the fastener can be rotated to apply torque to the fastener. In addition, the movement of the fastening assembly 12 may be utilized to drive the fastening assembly 121 to move to apply torque to the fastener.

[0092] In addition, fasteners generally have corresponding pre-tightening torques. When the corresponding pre-tightening torques are applied to the fasteners, the fasteners can play a better connecting role. For this purpose, a torque sensor can be set in the fastening assembly 121 to detect the torque applied to the fastener, so that the fastening assembly 121 can be used to apply the corresponding pre-tightening torque to the fastener. It should be noted that in addition to the above-mentioned monitoring of the torque applied to the fastener by the fastening assembly 121 to determine whether the fastener has reached the pre-tightening torque, it is also possible to determine whether the fastener has reached the pre-tightening torque by monitoring the rotation angle of the fastener and the stretching length of the fastener. For this purpose, a sensor for measuring the rotation angle of the fastener or a sensor for measuring the stretching length of the fastener can also be set in the fastening assembly 121 to determine whether the fastener has reached the pre-tightening torque.

[0093] On this basis, the fastening assembly 12 in the embodiment of the present disclosure further includes a marking component 122 , which can be used to mark a specific fastener to distinguish it from other fasteners.

[0094] It should be noted that in the embodiment of the present disclosure, the type of fasteners that the marking component 122 is used to mark is not limited. For a battery pack, the number of fasteners in the battery pack is generally multiple. For example, for the battery pack box and the upper cover, a circle of fasteners is generally provided along the circumferential edge of the upper cover. The fastening component 121 of the present disclosure can be used to tighten the above fasteners in sequence. For this purpose, the marking component 122 can be used to mark the fastened fasteners, while the unfastened fasteners are not marked. In this way, it is possible to intuitively distinguish which fasteners are fastened and which are not fastened. In addition, in some embodiments of the present disclosure, the fastening component 121 can also be used to record the results of fastening of fasteners. In this way, it can be determined which fasteners have qualified fastening results and which fasteners have unqualified fastening results. For this purpose, the marking component 122 can also be used to mark the fasteners with unqualified fastening results. In this way, it can be intuitively distinguished which fasteners have qualified fastening results and which fasteners have unqualified fastening results, so as to facilitate subsequent processing of the fasteners with unqualified fastening results, such as re-tightening or replacing the fasteners.

[0095] Furthermore, in the disclosed embodiments, the method by which marking assembly 122 marks fasteners is not limited, as long as it can distinguish marked fasteners from unmarked fasteners. For example, marking assembly 122 can be provided in a manner similar to stamping a fastener; alternatively, marking assembly 122 can be provided in a manner similar to drawing a line with a marker pen.

[0096] On this basis, when marking fasteners using the marking component 122 in a manner similar to drawing lines with a marker pen, lines can be drawn only on the fasteners; lines can also be drawn on both the fasteners and the structural parts on which the fasteners are installed. In this way, the marking lines can be used to monitor whether the fasteners are loose or have been disassembled.

[0097] It should be noted that in the embodiments of the present disclosure, the camera assembly 125 can be independently arranged from the operating platform 11, the fastening assembly 12, or the drive assembly 13, that is, the camera assembly 125 can be independently installed near the operating platform 11, so that the camera assembly 125 remains relatively independent. In addition, in some embodiments of the present disclosure, the camera assembly 125 can also be integrated with the operating platform 11, the fastening assembly 12, or the drive assembly 13, that is, the camera assembly 125 can be installed together with the above-mentioned operating platform 11, the fastening assembly 12, or the drive assembly 13. For example, with reference to Figures 1 to 3, the camera assembly 125 can be installed together with the fastening assembly 12, so that the camera assembly 125 can move together with the fastening assembly 12.

[0098] In addition, it should be noted that in the embodiments of the present disclosure, the type of camera of the camera assembly 125 is not limited. For example, a wide-angle lens can be selected to set the camera assembly 125 in the embodiments of the present disclosure. The wide-angle lens captures a wider picture and can better obtain the image of the fastener. In addition, in the embodiments of the present disclosure, the number of cameras included in the camera assembly 125 is not limited. For example, in some embodiments of the present disclosure, the number of cameras included in the camera assembly 125 can be set to two or more. In this way, the images of the fastener captured by different cameras can be compared, and the position of the fastener can be determined more accurately.

[0099] On this basis, the battery pack fastening system 1 provided in the embodiment of the present disclosure also includes a control module. The control module can be used to process the image of the fastener captured by the camera assembly 125 and can be used to control the drive assembly 13 to control the movement of the fastening assembly 12, thereby controlling the fastening assembly 12 to move to any position within the operating space. If the fastening assembly 121 and the marking assembly 122 include a driving member, the control module can also be used to control the fastening assembly 121 and the marking assembly 122.

[0100] It should be noted that, in the embodiments of the present disclosure, the type of control module is not limited. For example, a programmable logic controller (PLC) can be used to set the control module, or other devices with processing functions can be used to set the control module, such as an industrial computer. In addition, in the embodiments of the present disclosure, a distributed control system can also be used to perform distributed processing on the image screens captured by the fastening assembly 12, the drive assembly 13, and the camera assembly 125. Specifically, a PLC can be set for the fastening assembly 12, a PLC can be set for the drive assembly 13, and an industrial computer can be set for the image screens captured by the above-mentioned PLC and the camera assembly 125. For this purpose, the industrial computer can also be referred to as a host computer. In this way, the strong processing power of the industrial computer can be used to process the image screens captured by the camera assembly 125, and the industrial computer can be used to transmit control signals to the above-mentioned PLC to achieve control of the movement of the above-mentioned fastening assembly 12 and the drive assembly 13.

[0101] On this basis, it can be considered that the control module in the embodiment of the present disclosure includes any device with processing function in the battery pack fastening system 1.

[0102] Thus, in the embodiment of the present disclosure, the control module can process the image of the fastener captured by the camera assembly 125, and thus determine the position of the fastener. On this basis, the control module can form a visual guide for the movement of the drive assembly 13 and the fastening assembly 12, so that the control module can control the drive assembly 13 to drive the fastening assembly 121 to move to the position corresponding to the corresponding fastener. On this basis, the fastening assembly 121 can be docked with the corresponding fastener, so that the fastening assembly 121 can be used to complete the fastening of the corresponding fastener. Furthermore, the control module can also control the drive assembly 13 to drive the marking assembly 122 to move to the position corresponding to the corresponding fastener. On this basis, the marking assembly 122 can be brought into contact with the corresponding fastener, so that the marking assembly 122 can be used to complete the marking of the corresponding fastener. At the same time, in the embodiment of the present disclosure, the control module controls the movement of the driving assembly 13 or the fastening assembly 12 based on the visual guidance of the movement of the driving assembly 13 or the fastening assembly 12 formed by the image picture obtained by the camera component 125. Therefore, it can form a good adaptation for battery packs of different models and specifications, as well as for fasteners in different positions of the battery pack. Therefore, the battery pack fastening system 1 provided in the embodiment of the present disclosure can be applied to the production of battery packs of different models and specifications.

[0103] On this basis, referring to Figures 1 to 3, in the embodiment of the present disclosure, the fastening assembly 12 includes a connecting bracket 123, which is fixedly connected to the free end of the driving assembly 13, the fastening component 121 and the marking component 122 are arranged and installed on the connecting bracket 123, and the camera component 125 is also installed on the connecting bracket 123.

[0104] It should be noted that the free end of the drive assembly 13 herein refers to the end of the drive assembly 13 that moves relatively. For example, referring to FIG1 , when the drive assembly 13 in the embodiment of the present disclosure is configured as a six-axis robot 131, the free end of the drive assembly 13 refers to the free end of the end arm of the six-axis robot 131. For configurations of the drive assembly 13 in other forms, reference can also be made to the above description for further understanding.

[0105] In this way, the connecting bracket 123 can be used to form a transition connection at the free end of the drive assembly 13. By installing the fastening component 121 and the marking component 122 on the connecting bracket 123, the installation of the fastening component 121 and the marking component 122 can be facilitated.

[0106] Furthermore, in the embodiment of the present disclosure, the specific structural form of the connecting bracket 123 is not limited. For example, referring to FIG. 2 and FIG. 3 , the connecting bracket 123 can be configured as a plate-shaped structure.

[0107] On this basis, the fastening assembly 121 and the marking assembly 122 can be arranged and installed on the connecting bracket 123. It should be noted that the fastening assembly 121 and the marking assembly 122 are arranged and installed on the connecting bracket 123, which means that the fastening assembly 121 and the marking assembly 122 extend in the same direction. In this way, it is convenient to position the fastening assembly 121 and the marking assembly 122, so that the control module can control the fastening assembly 121 or the marking assembly 122 to move to the position of the corresponding fastener.

[0108] For example, referring to Figures 1 and 2, for using a six-axis robot 131 as the drive assembly 13 in the embodiment of the present disclosure, the extension direction of the connecting bracket 123 can be set to be the same as the extension direction of the end robot arm of the six-axis robot 131, and the fastening component 121 and the marking component 122 can be arranged and installed on the connecting bracket 123 according to the extension direction of the end robot arm.

[0109] Furthermore, in the embodiment of the present disclosure, the camera assembly 125 can also be installed on the connecting bracket 123, so that the driving assembly 13 can be used to synchronously drive the camera assembly 125 and the fastening assembly 121 or the marking assembly 122 to move synchronously.

[0110] For this purpose, a mounting bracket may be provided on the camera assembly 125 , and the mounting bracket may be fixedly connected to the connecting bracket 123 , so that the camera of the camera assembly 125 may be mounted on the aforementioned mounting bracket.

[0111] Thus, through the above arrangement, the fastening assembly 121, the marking assembly 122, and the camera assembly 125 are mounted using the connecting bracket 123, which facilitates the fixed connection of the fastening assembly 121, the marking assembly 122, and the camera assembly 125 to the free end of the drive assembly 13. This also facilitates the control module's control over the movement of the fastening assembly 121, the marking assembly 122, and the camera assembly 125. Furthermore, mounting the camera assembly 125 on the connecting bracket 123 allows the image captured by the camera assembly 125 to follow the fastening assembly 121 or the marking assembly 122, and also allows the image of the fastener captured by the camera assembly 125 to be more targeted, allowing the control module to more accurately control the movement of the fastening assembly 121 or the marking assembly 122.

[0112] On this basis, in some embodiments of the present disclosure, the battery pack fastening system 1 further includes at least two fastening assemblies 121, all of which are arranged on a connecting bracket. Furthermore, in embodiments of the present disclosure, at least two camera assemblies 125 are provided, and each of the camera assemblies 125 and the fastening assemblies 121 are arranged on a connecting bracket 123 in a one-to-one correspondence.

[0113] It should be noted that in the embodiments of the present disclosure, the specific number of fastening assemblies 121 is not limited. For example, the number of fastening assemblies 121 can be set to two, or the number of fastening assemblies 121 can be set to more than two. For example, referring to Figures 2 and 3, the number of fastening assemblies 121 can be set to two in the manner shown in Figures 2 and 3. For setting the number of fastening assemblies 121 to more than two, the same setting can be used.

[0114] In addition, in the embodiment of the present disclosure, the relative positional relationship between the fastening assembly 121 and the marking assembly 122 is not limited. For example, referring to Figures 2 and 3, the marking assembly 122 can be set at one end of two or more arranged fastening assemblies 121. In addition, the marking assembly 122 can also be set between two or more arranged fastening assemblies 121.

[0115] Furthermore, in the embodiment of the present disclosure, the number of camera components 125 is also set to more than two, and all fastening components 121 are provided with camera components 125 in a one-to-one correspondence, and the camera components 125 are fixedly connected to the corresponding fastening components 121.

[0116] It should be noted that, in the embodiment of the present disclosure, "one-to-one correspondence between each fastening assembly 121 and a camera assembly 125" means that each fastening assembly 121 is provided with a corresponding camera assembly 125. Furthermore, in the embodiment of the present disclosure, the number of camera assemblies 125 can be set to be the same as the number of fastening assemblies 121, or the number of camera assemblies 125 can be set to be greater than the number of fastening assemblies 121. For example, for each marking assembly 122, a camera assembly 125 can also be provided for each marking assembly 122.

[0117] 2 and 3 , in some embodiments of the present disclosure, the camera assembly 125 may be provided only for the fastening assembly 121. In this regard, the relative positional relationship between the marking assembly 122 and the fastening assembly 121 may be utilized to position the marking assembly 122.

[0118] For example, referring to FIG. 2 , the number of the fastening components 121 can be set to two, and the number of the camera components 125 can be set to two, as shown in FIG. 2 .

[0119] Thus, by setting the number of fastening assemblies 121 to at least two, more than two fasteners can be fastened simultaneously, thereby improving the fastening efficiency of the battery pack fastening system 1 in the disclosed embodiment. Furthermore, by providing a camera assembly 125 for each fastening assembly 121, more precise visual guidance can be provided for the movement of each fastening assembly 121.

[0120] In order to further improve the scope of application of the battery pack fastening system 1 in the embodiments of the present disclosure, in some embodiments of the present disclosure, part of the fastening components 121 are arranged to have a fixed position relative to the connecting bracket 123, and another part of the fastening components 121 are arranged to have an adjustable position relative to the connecting bracket 123.

[0121] Specifically, referring to Figures 2 and 3, in the disclosed embodiment, the fastening assembly 121 includes a fixed fastening assembly 121a and a movable fastening assembly 121b. There is only one fixed fastening assembly 121a, which is fixedly connected to a connecting bracket 123. The movable fastening assembly 121b is capable of adjusting its position relative to the connecting bracket 123. Furthermore, the marking assembly 122 is also fixedly connected to the connecting bracket 123 near the fixed fastening assembly 121a.

[0122] For example, referring to FIG2 , a guide rail can be provided on the connecting bracket 123, and a guide groove can be provided on the movable fastening assembly 121b. By installing the guide groove on the guide rail, the guide rail can be used to guide the movement of the movable fastening assembly 121b. Further, referring to FIG1 and FIG2 , when a six-axis robot 131 is used as the drive assembly 13 in the embodiment of the present disclosure, the extension direction of the guide rail can be set to be perpendicular to the extension direction of the end robot arm.

[0123] Through the above-described arrangement, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by configuring the fastening assembly 121 as a fixed fastening assembly 121a and a movable fastening assembly 121b, the relative position between the movable fastening assembly 121b and the fixed fastening assembly 121a can be adjusted to match the relative positional relationship between the fixed fastening assembly 121a and the movable fastening assembly 121b with the relative positional relationship between different fasteners. This allows the battery pack fastening system 1 provided in the embodiment of the present disclosure to fasten different fasteners simultaneously, further improving the adaptability of the battery pack fastening system 1 in the embodiment of the present disclosure. At the same time, by arranging the marking assembly 122 close to the fixed fastening assembly 121a, the position of the fixed fastening assembly 121a can be conveniently used to position the marking assembly 122, thereby conveniently controlling the position of the marking assembly 122.

[0124] Furthermore, referring to FIG3 , to facilitate adjustment of the relative position of the movable fastening assembly 121b, in some embodiments of the present disclosure, the fastening assembly 12 further includes a first driver 124. Specifically, the first driver 124 is disposed between the connecting bracket 123 and the movable fastening assembly 121b. The first driver 124 is configured to drive the movable fastening assembly 121b to move relative to the connecting bracket 123. Furthermore, the first driver 124 is also electrically coupled to a control module, which can control the first driver 124 to drive the movement of the movable fastening assembly 121b based on an image of the fastener captured by the camera assembly 125.

[0125] It should be noted that, in the embodiment of the present disclosure, the specific structural form of the first driving member 124 is not limited. For example, a pneumatic cylinder, a hydraulic cylinder, or a motor can be selected as the first driving member 124 in the embodiment of the present disclosure. Specifically, if a pneumatic cylinder or a hydraulic cylinder is selected as the first driving member 124 in the embodiment of the present disclosure, the output shaft of the pneumatic cylinder or the hydraulic cylinder can be used to directly drive the movable fastening component 121b to move so as to adjust its position relative to the fixed fastening component 121a; if a motor is selected as the first driving member 124 in the embodiment of the present disclosure, the movable fastening component 121b can be driven to move so as to adjust its position relative to the fixed fastening component 121a through a gear rack transmission or a screw transmission.

[0126] For example, in some embodiments of the present disclosure, a stepper motor can be selected as the first driving member 124 in the embodiments of the present disclosure, and the output shaft of the stepper motor is connected to the movable fastening assembly 121b through a screw transmission mechanism, so that the movable fastening assembly 121b can be driven to move relative to the connecting bracket 123, and then the position of the movable fastening assembly 121b relative to the fixed fastening assembly 121a can be adjusted.

[0127] It should be noted that if the number of movable fastening components 121b is two or more, a first driving member 124 can be set between the connecting bracket 123 and each movable fastening component 121b for each movable fastening component 121b on the connecting bracket 123. In this way, each first driving member 124 can be used to drive the corresponding movable fastening component 121b to adjust its position relative to the fixed fastening component 121a, so that the relative position between the fixed fastening component 121a and each movable fastening component 121b can correspond to the relative positions of multiple fasteners on the battery pack.

[0128] On this basis, the first driving member 124 is also electrically connected to the control module, so that the control module can control the movement of the first driving member 124 according to the image of the fastener obtained by the camera component 125, so that the relative position relationship between the fixed fastening component 121a and the movable fastening component 121b corresponds to the relative position relationship of the fastener.

[0129] In this way, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by setting the first driving member 124 between the connecting bracket 123 and the movable fastening assembly 121b, and electrically connecting the first driving member 124 to the control module, the control module can be used to control the movement of the movable fastening assembly 121b based on the image of the fastener obtained by the camera assembly 125, so that the movable fastening assembly 121b automatically moves to a position matching the corresponding fastener, thereby being able to accurately control the relative position between the fixed fastening assembly 121a and the movable fastening assembly 121b.

[0130] On this basis, referring to Figures 2 and 3, in some embodiments of the present disclosure, the marking component 122 and the movable fastening component 121b are respectively arranged on both sides of the fixed fastening component 121a, and the camera component 125 corresponding to the fixed fastening component 121a is arranged between the marking component 122 and the fixed fastening component 121a.

[0131] Specifically, referring to Figures 2 and 3 , regarding the overall arrangement of the marking assembly 122, the fixed fastening assembly 121a, and the movable fastening assembly 121b, it can be seen that the marking assembly 122 is located at one end, while the movable fastening assembly 121b is located at the other end. This provides space for the movable fastening assembly 121b to move. Furthermore, when the marking assembly 122 is fixedly mounted on the connecting bracket 123, positioning the marking assembly 122 close to the fixed fastening assembly 121a ensures that the relative positional relationship between the marking assembly 122 and the fixed fastening assembly 121a is fixed. Thus, the position of the fixed fastening assembly 121a can be used to indirectly determine the position of the marking assembly 122, thereby controlling the movement of the marking assembly 122. Furthermore, by arranging the camera assembly 125 corresponding to the fixed fastening assembly 121a between the marking assembly 122 and the fixed fastening assembly 121a, it is equivalent to arranging the camera assembly 125 close to the marking assembly 122, so that the camera assembly 125 can also be used to provide visual guidance for the movement of the marking assembly 122.

[0132] In addition, referring to FIG. 3 , in order to improve the quality of the image of the fastener captured by the camera assembly 125 , in some embodiments of the present disclosure, a fill light 1251 is further provided for illuminating the fastener.

[0133] Specifically, referring to FIG. 3 , in some embodiments of the present disclosure, the camera assembly 125 includes a fill light 1251 and an image sensor 1252. The light source of the fill light 1251 is oriented in the same direction as the lens of the image sensor 1252. The fill light 1251 is used to provide fill light to the fastener being photographed by the image sensor 1252. Furthermore, in embodiments of the present disclosure, the image sensor 1252 is electrically connected to a control module, which is capable of acquiring and processing images captured by the image sensor 1252.

[0134] It should be noted that, in the embodiment of the present disclosure, the specific structural form of the fill light 1251 is not limited. For example, the fill light 1251 can be set as a surface light source, or can be set as an arranged point light source.

[0135] In this way, the fill light 1251 can be used to illuminate the fastener, so that the image of the fastener taken by the camera component 125 can have a higher quality even in dim ambient light conditions, thereby improving the accuracy of the control module's control of the movement of the fastening assembly 12 based on the image of the fastener taken by the camera component 125.

[0136] It should be noted that when processing image frames, strong processing capabilities are generally required. Therefore, an industrial computer or other electronic device with strong processing capabilities can be set in the control module of the embodiment of the present disclosure, and the image frames obtained by the camera 1252 can be transmitted to the industrial computer, and the industrial computer can be used to process the image frames.

[0137] On this basis, referring to FIG3 , in the embodiment of the present disclosure, the fill light 1251 is set as an annular light source, and the annular light source is set between the camera 1252 and the fastener, and the lens of the camera 1252 is located on the axis of the annular light source.

[0138] It should be noted that, here, setting the annular light source between the camera 1252 and the fastener is equivalent to setting the lens of the camera 1252 on the side of the annular light source close to the drive assembly 13.

[0139] Specifically, referring to FIG3 , configuring the fill light 1251 as a ring-shaped light source means that the main structure of the fill light 1251 is annular. For example, referring to FIG3 , the shell of the fill light 1251 can be configured as an annular shape, and a circle of LED point light sources can be arranged circumferentially on the annular shell of the fill light 1251.

[0140] In addition, it should be noted that, in the embodiment of the present disclosure, referring to FIG. 3 and in combination with FIG. 1 , the lens of the camera 1252 is disposed on the side of the annular light source close to the drive assembly 13, which can also be considered as the fill light 1251 being disposed in the direction of the lens of the fill light 1251. Furthermore, referring to FIG. 3 , the direction of the lens of the camera 1252 is also disposed on the axis of the annular light source.

[0141] It can be understood that in the embodiment of the present disclosure, the distance between the annular light source and the lens of the camera 1252 can be adjusted according to the focal length of the lens of the camera 1252, so that the annular light source does not affect the image of the fastener captured by the lens of the camera 1252 through the annular light source.

[0142] Through the above-mentioned setting, the fill light 1251 is set as a ring light source, and the lens of the camera 1252 is set on the axis of the ring light source, which can further improve the fill light effect of the fill light 1251, thereby further improving the quality of the image at the fastener obtained by the camera component 125.

[0143] In addition, in some embodiments of the present disclosure, a driving member may be provided in the marking component 122 to drive the marking component 122 to complete the marking of the fasteners, thereby simplifying the movement of the driving assembly 13 .

[0144] Specifically, referring to Figures 3 and 4, in some embodiments of the present disclosure, the marking assembly 122 includes a marking tool 1221 and a second driving member 1222. The second driving member 1222 is disposed between the marking tool 1221 and the connecting bracket 123, and is used to drive the marking tool 1221 to move relative to the connecting bracket 123. In addition, in the embodiment of the present disclosure, the second driving member 1222 is also electrically connected to a control module, which can control the second driving member 1222 to drive the movement of the marking tool 1221 based on the image of the fastener captured by the camera assembly 125.

[0145] It should be noted that, in the embodiment of the present disclosure, the type of the second driving member 1222 is not limited. For example, the second driving member 1222 can be set as a cylinder, a hydraulic cylinder, or a motor, etc. In addition, in the embodiment of the present disclosure, the type of the marking tool 1221 is not limited. It can be adaptively set according to the marking form of the fastener by the aforementioned marking component 122. For example, with reference to the above description, if the marking method of the marking component 122 is set to a method similar to stamping, the marking tool 1221 can be set to a stamp head; if the marking method of the marking component 122 is set to a method similar to drawing a line with a marker pen, the marking tool 1221 can be set to a liner pen.

[0146] In addition, in the embodiment of the present disclosure, the movement direction of the second driving member 1222 driving the marking tool 1221 is not limited. The second driving member 1222 can have multiple degrees of freedom or only one degree of freedom. It can be adaptively set according to the position where the fastener needs to be marked, so that the marking tool 1221 can mark the fastener at any position in the operating space.

[0147] For example, referring to FIG1 , a six-axis robot 131 can be used as the drive assembly 13 in the disclosed embodiment. The six-axis robot 131 is already capable of driving the fastening assembly 12 to any position within the operating space and adjusting the fastening assembly 12 to any angle. In this case, in conjunction with FIG4 , only the second drive member 1222 can be used to extend or retract the marking tool 1221 relative to the fastener. For this purpose, the second drive member 1222 can be configured as a pneumatic cylinder or a hydraulic cylinder. This simplifies the type of the second drive member 1222 and facilitates its configuration.

[0148] For example, referring to FIG. 4 , the second drive member 1222 can be configured as shown in FIG. Specifically, referring to FIG. 4 and in combination with FIG. 1 , the second drive member 1222 can be configured as a cylinder, and the extension direction of the cylinder's extended axis can be configured to be parallel to the extension direction of the end arm of the six-axis robot 131. Thus, when a fastener needs to be fastened and marked, the drive assembly 13 can first be used to move the fastening assembly 12 to a pre-marking position. In this position, the marking tool 1221 is already facing the fastener to be marked. The second drive member 1222 then drives the marking tool 1221 toward the fastener, thereby completing the marking of the fastener. Finally, after the marking tool 1221 completes the marking of the fastener, the second drive member 1222 drives the marking tool 1221 away from the fastener. At this point, the marking assembly 122 completes the fastener marking process.

[0149] On this basis, by electrically connecting the second driving member 1222 to the control module, the control module can provide visual guidance for the movement of the marking tool 1221 driven by the second driving member 1222 based on the image at the fastener obtained by the camera component 125, thereby accurately controlling the movement of the marking tool 1221.

[0150] In this way, in the battery pack fastening system 1 provided in the application embodiment, by setting an independent second driving member 1222 in the marking assembly 122, on the basis of the driving assembly 13 driving the fastening assembly 12 to move, the second driving member 1222 can be used to independently drive the movement of the marking tool 1221, thereby being able to more accurately control the movement of the marking tool 1221.

[0151] Further, referring to FIG. 4 , in some embodiments of the present disclosure, the fasteners are marked in a manner similar to drawing lines with a marker.

[0152] 4 and 7 , in the disclosed embodiment, the marking tool 1221 includes a marking pen 12211 and a pen cap 12212 . The marking pen 12211 is provided with a marking portion at one end away from the drive assembly 13 . The marking portion is used to mark the fasteners, and the pen cap 12212 is detachably covered on the marking portion.

[0153] It should be noted that in the disclosed embodiment, the marker pen 12211 can be configured as various types of liner pens, such as an ink pen or a watercolor pen. The marking portion of the marker pen 12211 can be considered the line drawing portion of these various types of liner pens. When the marker pen 12211 is not needed to mark a fastener, the marking portion can be protected by covering it with a pen cap 12212. When the marker pen 12211 is needed to mark a fastener, the pen cap 12212 can be removed from the marker pen 12211.

[0154] With the above arrangement, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, marking the fastener with a marking pen 12211 simplifies the structure of the marking tool 1221 and simplifies the marking method of the fastener with the marking pen 12211. Furthermore, the provision of the pen cap 12212 protects the marking pen 12211 and extends its service life.

[0155] On this basis, referring to Figures 1, 6 and 7, in some embodiments of the present disclosure, the battery pack fastening system 1 also includes a clamping assembly 14, which remains relatively fixed to the operating platform 11; the clamping assembly 14 includes at least two clamping members 141, and the clamping members 141 can approach or move away from each other to clamp or release the pen cap 12212.

[0156] It should be noted that in some embodiments of the present disclosure, the clamping assembly 14 can be set as a non-powered mechanical structure. For example, in some embodiments of the present disclosure, the clamping assembly 14 can be set as a press-to-self-locking structure; in addition, the clamping assembly 14 can also be set as a clamping structure with a driving part, which is not limited in the embodiments of the present disclosure.

[0157] 1 , in the disclosed embodiment, the clamping assembly 14 can be separately provided and can be provided near the operating platform 11. Furthermore, the clamping assembly 14 can also be provided on the operating platform 11 as long as it does not affect the placement of the battery pack on the operating platform 11.

[0158] Thus, in the battery pack fastening system 1 provided by the embodiment of the present disclosure, when it is necessary to use the marking pen 12211 to mark a fastener, the driving assembly 13 can be used to drive the marking pen 12211 and the pen cap 12212 to move between the clamping member 141. At this time, the pen cap 12212 is clamped by the clamping member 141. When the driving assembly 13 or the second driving member 1222 drives the marking pen 12211 away from the clamping member 141, the marking pen 12211 and the pen cap 12212 can be separated. After the marking pen 12211 has finished marking the fastener, when the driving assembly 13 or the second driving member 1222 drives the marking pen 12211 to insert the pen cap 12212, the clamping member 141 releases the pen cap 12212, so that the pen cap 12212 moves with the marking pen 12211, thereby protecting the marking pen 12211.

[0159] On this basis, in some embodiments of the present disclosure, in order to make the clamping assembly 14 clamp or release the pen cap 12212 more precise, the clamping assembly 14 is also configured as a clamping structure with a driving member.

[0160] Specifically, referring to FIG. 6 , in some embodiments of the present disclosure, the clamping assembly 14 further includes a third driving member 142 , and the third driving member 142 is used to drive the clamping members 141 to move closer to or away from each other.

[0161] It should be noted that in some embodiments of the present disclosure, the type of the third driving member 142 is not limited. For example, the third driving member 142 can be set as a driving member such as a cylinder, a hydraulic cylinder, or a motor. In addition, the number of third driving members 142 can be set to be the same as the number of clamping members 141, and the third driving members 142 and the clamping members 141 can be set to a one-to-one correspondence; in addition, the number of third driving members 142 can be set to one, and by providing a transmission structure between the third driving member 142 and all the clamping members 141, one third driving member 142 can drive all the clamping members 141 to move closer to or away from each other.

[0162] For example, the following description is made by taking the example of setting the number of the clamping members 141 to two and setting the third driving member 142 to a cylinder.

[0163] Specifically, a "Y"-shaped guide rail can be provided on the output shaft of the cylinder, and two clamping members 141 can be respectively provided on the two forks of the "Y"-shaped guide rail. The clamping members 141 can be limited so that the clamping members 141 do not move as the extension shaft of the cylinder drives the "Y"-shaped guide rail to extend or retract. In this way, when the extension shaft of the cylinder drives the "Y"-shaped guide rail to extend, the two clamping members 141 will move closer to each other, thereby allowing the clamping members 141 to clamp the pen cap 12212; when the extension shaft of the cylinder drives the "Y"-shaped guide rail to retract, the two clamping members 141 will move away from each other, thereby allowing the clamping members 141 to release the pen cap 12212.

[0164] On this basis, in the embodiment of the present disclosure, the third driving member 142 is also electrically connected to the control module. The control module can control the movement of the third driving member 142, thereby controlling the clamping member 141 to clamp or release the pen cap 12212. Specifically, when the marking pen 12211 needs to mark a fastener, the driving assembly 13 and the second driving member 1222 drive the marking pen 12211 and the pen cap 12212 to move between the clamping member 141. At this time, the control module controls the movement of the third driving member 142 to cause the clamping member 141 to clamp the pen cap 12212. Subsequently, the driving assembly 13 or the second driving member 1222 drives the marking pen 12211 to move away from the pen cap 12212, thereby separating the marking pen 12211 and the pen cap 12212. Thereafter, the control module controls the movement of the marking pen 12211 to complete the marking of the fastener.

[0165] After the marking pen 12211 has finished marking the fastener, the control module controls the drive assembly 13 and the second drive member 1222 to insert the marking pen 12211 into the pen cap 12212, connecting the marking pen 12211 and the pen cap 12212. The control module then controls the movement of the third drive member 142, causing the clamping member 141 to release the pen cap 12212. The drive assembly 13 then drives the fastening assembly 12 to move to another location, allowing the fastening assembly 12 to perform other tasks, such as tightening the fastener with the fastening assembly 121.

[0166] In this way, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by configuring the clamping assembly 14 to include a third driving member 142, the control module can be conveniently used to control the movement of the third driving member 142, thereby conveniently controlling the clamping member 141 to clamp or release the pen cap 12212.

[0167] In addition, in order to smoothly separate the pen cap 12212 and the marking pen 12211, and at the same time, conveniently connect the marking pen 12211, in some embodiments of the present disclosure, the detachable connection between the marking pen 12211 and the pen cap 12212 is also set to a magnetic connection.

[0168] Specifically, a magnet 01 can be set on the part of the marking pen 12211 that is in contact with the pen cap 12212, and a magnet 01 can be set on the part of the pen cap 12212 that is in contact with the marking pen 12211. The marking pen 12211 and the pen cap 12212 can be attracted to each other through the attraction of opposite poles of the magnet 01, thereby connecting the marking pen 12211 and the pen cap 12212 together.

[0169] It should be noted that, in addition to the magnet 01 described above, an electromagnet may be provided on the marking pen 12211 or the pen cap 12212. Alternatively, a magnet 01 or an electromagnet may be provided on one of the marking pen 12211 or the pen cap 12212, and a ferromagnetic metal may be provided on the other of the marking pen 12211 or the pen cap 12212.

[0170] In this way, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by setting the connection between the marking pen 12211 and the pen cap 12212 to a magnetic connection, the connection between the marking pen 12211 and the pen cap 12212 can be made simple and reliable.

[0171] Furthermore, in some embodiments of the present disclosure, the main body material of the marking pen 12211 is set to ferromagnetic metal. Referring to Figure 7, a plurality of magnets 01 are circumferentially distributed on the contact surface of the pen cap 12212 for contacting the marking pen 12211.

[0172] Thus, by setting the main body material of the marker pen 12211 to ferromagnetic metal and providing the magnet 01 on the pen cap 12212, the magnet 01 provided on the pen cap 12212 and the marker pen 12211 can be attracted to each other regardless of the magnetic properties of the magnet 01, thereby facilitating the connection between the pen cap 12212 and the marker pen 12211. Furthermore, by setting the main body material of the marker pen 12211 to ferromagnetic metal, no additional configuration is required for the marker pen 12211, thus simplifying the structure of the marker pen 12211 and facilitating its manufacture.

[0173] In addition, in some embodiments of the present disclosure, referring to FIG. 7 , a guiding slope 1411 is further provided on the clamping member 141 , and the guiding slope 1411 is used to guide the pen caps 12212 to move between the clamping members 141 .

[0174] For example, referring to Figure 7, in some embodiments of the present disclosure, a clamping portion can be set between adjacent clamping members 141 so that the shape of the clamping portion matches the shape of the pen cap 12212, thereby achieving clamping of the pen cap 12212. To this end, the clamping portion can be set into a conical groove on the side facing the marking pen 12211. In this way, the inclined surface of the conical groove can be used to guide the pen cap 12212 to move between the clamping members 141.

[0175] Through the above arrangement, the guiding slope 1411 can be used to guide the pen cap 12212 to move between the clamping members 141, so that the pen cap 12212 can move smoothly between the clamping members 141, and the clamping members 141 can smoothly clamp the pen cap 12212.

[0176] In addition, referring to FIG. 7 , in some embodiments of the present disclosure, the clamping assembly 14 further includes a pen cap detection sensor 143 , which is used to detect whether the pen cap 12212 is located between the clamping members 141 .

[0177] It should be noted that in the embodiment of the present disclosure, the specific type of the pen cap detection sensor 143 is not limited. For example, the pen cap detection sensor 143 can be set as a contact sensor. In this way, by arranging the pen cap detection sensor 143 at a position where the clamping member 141 can contact the pen cap 12212, it is possible to use the detection sensor to detect whether the pen cap 12212 is located between the clamping member 141. In addition, a non-contact sensor can also be used as the pen cap detection sensor 143 in the embodiment of the present disclosure, such as a radar, infrared, or photoelectric sensor 1431. The embodiment of the present disclosure is not limited to this.

[0178] On this basis, in the embodiment of the present disclosure, the pen cap detection sensor 143 is also electrically connected to the control module. In this way, the control module can obtain a signal from the pen cap detection sensor 143 to determine whether the pen cap 12212 is clamped between the clamping members 141. Furthermore, the prerequisite for the control module to control the marking pen 12211 to mark the fastener includes: the pen cap detection sensor 143 detects that the pen cap 12212 is located between the clamping members 141.

[0179] Here, only when the pen cap detection sensor 143 detects that the pen cap 12212 is located between the clamping members 141 does the control component control the drive assembly 13 and the second drive member 1222 to control the marking pen 12211 to move to the position corresponding to the fastener to mark the fastener. This also indicates that the pen cap 12212 is not on the marking pen 12211, and the fastener can be marked using the marking pen 12211. If the pen cap detection sensor 143 does not detect that the pen cap 12212 is located between the clamping members 141, it can be assumed that the pen cap 12212 is on the marking pen 12211, and the fastener cannot be successfully marked using the marking pen 12211.

[0180] Thus, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by providing the pen cap detection sensor 143, the pen cap detection sensor 143 can be used to conveniently detect whether the pen cap 12212 is located between the clamping members 141. Furthermore, by electrically connecting the pen cap detection sensor 143 to the control module, the control module can obtain a signal indicating whether the pen cap 12212 is located between the clamping members 141, as indicated by the pen cap detection sensor 143. Based on this signal, the marking pen 12211 can be controlled to mark the fastener, thereby further improving the adaptability of the battery pack fastening system 1 in the embodiment of the present disclosure.

[0181] On this basis, referring to FIG. 6 and FIG. 7 , in some embodiments of the present disclosure, in order to improve the accuracy of the pen cap detection sensor 143 , the pen cap detection sensor 143 is further configured as a photoelectric sensor 1431 .

[0182] Here, the position of the photoelectric sensor 1431 can be adaptively set to match the position of the pen cap 12212 between the clamping members 141. When the pen cap 12212 is located between the clamping members 141, the pen cap 12212 blocks the light signal of the photoelectric sensor 1431, thereby causing the output voltage of the photoelectric sensor 1431 to change accordingly. On this basis, the control module can be used to monitor the output voltage of the photoelectric sensor 1431, so as to determine whether the pen cap 12212 is located between the clamping members 141.

[0183] For example, referring to Figures 6 and 7 , in the embodiment of the present disclosure, a through-beam photoelectric sensor 1431 can be used as the pen cap detection sensor 143 in the embodiment of the present disclosure. Specifically, the through-beam photoelectric sensor 1431 includes a light output end and a light receiving end. When the clamping member 141 is located between the light output end and the light receiving end, the through-beam photoelectric sensor 1431 can block the propagation of light between the light output end and the light receiving end, thereby determining whether the pen cap 12212 is located between the clamping member 141.

[0184] Thus, in the embodiment of the present disclosure, by setting the pen cap detection sensor 143 as a photoelectric sensor 1431 , the accuracy of the detection result of the pen cap detection sensor 143 on whether the pen cap 12212 is located between the clamping members 141 can be improved.

[0185] In addition, referring to Figures 2 and 5, in some embodiments of the present disclosure, the fastening assembly 121 also includes a fastening tool 1211 and a fourth driving member 1212, and the fourth driving member 1212 is arranged between the fastening tool 1211 and the connecting bracket 123, and the fourth driving member 1212 can drive the fastening tool 1211 to move relative to the connecting bracket 123.

[0186] It should be noted that in the disclosed embodiment, the type of the fourth driving member 1212 is not limited. For example, the fourth driving member 1212 can be configured as a pneumatic cylinder, a hydraulic cylinder, or a motor. Furthermore, in the disclosed embodiment, the manner in which the fourth driving member 1212 drives the fastening tool 1211 is not limited. The fourth driving member 1212 can have multiple degrees of freedom or only one degree of freedom. Furthermore, it should be noted that in the disclosed embodiment, the fastening tool 1211 can include a built-in driving member for driving the fastener to rotate.

[0187] For example, referring to FIG1 , a six-axis robot 131 can be used as the drive assembly 13 in the disclosed embodiment. The six-axis robot 131 is already capable of driving the fastening assembly 12 to any position within the operating space and adjusting the fastening assembly 12 to any angle. In this case, only the fourth drive member 1212 can be used to extend or retract the fastening tool 1211 relative to the fastener. For this purpose, the fourth drive member 1212 can be configured as a pneumatic cylinder or a hydraulic cylinder. This simplifies the type of the fourth drive member 1212 and facilitates its configuration.

[0188] For example, referring to FIG5 , the fourth driving member 1212 can be configured as shown in FIG5 . Specifically, referring to FIG1 and FIG5 , the fourth driving member 1212 can be configured as a cylinder, and the extension direction of the cylinder's extended axis can be set to be parallel to the extension direction of the end manipulator arm of the six-axis robot 131. In this way, when it is necessary to tighten a fastener, the driving assembly 13 can first be used to move the fastening assembly 12 to a pre-tightening position. In this position, the fastening tool 1211 is already facing the fastener to be tightened. Thereafter, the fourth driving member 1212 drives the fastening tool 1211 to move toward the fastener, thereby completing the fastening of the fastener. Finally, after the fastening tool 1211 completes the fastening of the fastener, the fourth driving member 1212 drives the fastening tool 1211 away from the fastener. At this point, the fastening assembly 121 completes the fastening process of the fastener.

[0189] On this basis, by electrically connecting the fourth driving member 1212 to the control module, the control module can provide visual guidance for the movement of the fourth driving member 1212 driving the fastening tool 1211 based on the image of the fastener obtained by the camera component 125, thereby accurately controlling the movement of the fastening tool 1211.

[0190] In addition, for the battery pack fastening system 1 in the embodiment of the present disclosure including the second driving member 1222, the type of the fourth driving member 1212 can be set to be the same as the type of the second driving member 1222. For example, with reference to Figures 2, 4, and 5, in some embodiments of the present disclosure, the second driving member 1222 and the fourth driving member 1212 can both be set as cylinders.

[0191] In this way, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, by setting an independent fourth driving member 1212 in the fastening assembly 121, on the basis of the driving assembly 13 driving the fastening assembly 12 to move, the fourth driving member 1212 can be used to independently drive the fastening tool 1211 to move, thereby being able to more accurately control the movement of the fastening tool 1211.

[0192] 8 , in some embodiments of the present disclosure, the operating platform 11 includes a lifting mechanism 111, which includes a base 1111, a lifting member 1112, and a fifth driving member 1113. The fifth driving member 1113 is disposed between the base 1111 and the lifting member 1112. The fifth driving member 1113 is configured to drive the lifting member 1112 to move vertically, so that the lifting member 1112 lifts the tray 114. Furthermore, the fifth driving member 1113 is electrically connected to a control module, which is capable of controlling the fifth driving member 1113 to drive the movement of the lifting member 1112.

[0193] It should be noted that, in the embodiment of the present disclosure, the type of the fifth driving member 1113 is not limited, and the fifth driving member 1113 can be set to a cylinder, a hydraulic cylinder, or a motor, etc. In addition, when the fifth driving member 1113 is set to a cylinder or a hydraulic cylinder, the extension direction of the output shaft of the fifth driving member 1113 can be set to be along the vertical direction, so that the fifth driving member 1113 can be used to directly drive the lifting member 1112 to move in the vertical direction; the extension direction of the output shaft of the fifth driving member 1113 can also be set to have an angle with the vertical direction, and the movement direction of the output shaft of the fifth driving member 1113 can be changed by a transmission mechanism, so that the fifth driving member 1113 can also drive the lifting member 1112 to move in the vertical direction.

[0194] For example, referring to Figures 8 and 10, in some embodiments of the present disclosure, the fifth driving member 1113 can be configured as a cylinder, and the extension direction of the cylinder output shaft can be configured to be horizontal. By providing a lifting slope 11131 on the cylinder output shaft and a guide wheel 11121 on the lifting member 1112, the cooperation between the lifting slope 11131 and the guide wheel 11121 can enable the fifth driving member 1113 to lift or lower the lifting member 1112 in the vertical direction.

[0195] In addition, referring to Figure 10, in the embodiment of the present disclosure, a cylinder can also be used as the fifth driving member 1113, and two lifting inclined surfaces 11131 are connected to the output shaft of the cylinder, and two guide wheels 11121 are correspondingly provided on the lifting member 1112. In this way, one cylinder can be used to simultaneously drive different parts of the lifting member 1112 to lift or lower, which can reduce the number of cylinders used and also make it easier to control the lifting or lowering of the lifting member 1112.

[0196] On this basis, in the embodiment of the present disclosure, by electrically connecting the fifth driving member 1113 to the control module, the image captured by the camera assembly 125 can be used to provide visual guidance for the movement of the fifth driving member 1113. In addition, other control signals can also be used to control the fifth driving member 1113 to raise or lower the lifting member 1112.

[0197] Thus, in the battery pack securing system 1 provided in the disclosed embodiment, by configuring the operating platform 11 with a lifting function, it is possible to further facilitate the matching of the relative positions of the battery pack and the securing assembly 12. This also simplifies the movement and control of the drive assembly 13. Furthermore, this configuration also expands the operating range of the battery pack securing system 1 in the disclosed embodiment.

[0198] On this basis, referring to Figures 1, 8 and 11, in some embodiments of the present disclosure, there are two lifting mechanisms 111, and the two lifting mechanisms 111 are arranged opposite to each other, with a gap between the two lifting mechanisms 111, which forms a transportation path for the transport trolley and the pallet 114 to transport the battery pack. At the same time, a blocking assembly 112 is provided on the base 1111 of the lifting mechanism 111. The blocking assembly 112 includes a blocking member 1121 and a sixth driving member 1122. The sixth driving member 1122 is used to drive the blocking member 1121 to move to the transportation path formed by the above-mentioned gap, so as to limit the transport trolley between the two lifting mechanisms 111. In addition, the sixth driving member 1122 is electrically connected to the control module, and the control module can control the sixth driving member 1122 to drive the movement of the blocking member 1121 to limit or release the limit of the transport trolley.

[0199] Regarding this, it needs to be explained that in the production line of the battery pack, AGV and pallet 114 are often used to transport the battery pack between the various stations of the production line. In view of this situation, referring to Figures 1 and 8, in the embodiment of the present disclosure, the number of jacking mechanisms 111 is set to two, and the gap between the two jacking mechanisms 111 can be used to form the AGV's transportation path for the battery pack. Specifically, when the transport trolley transports the battery pack, the pallet 114 is set above the transport trolley, and the battery pack is set inside the pallet 114. Regarding this, when the transport trolley carries the pallet 114 to transport it between the two jacking mechanisms 111, the fifth driving member 1113 can be used to drive the lifting member 1112 to lift the pallet 114, so that the pallet 114 can be separated from the transport trolley to facilitate the positioning of the pallet 114. At the same time, the transport trolley can be moved to other stations to perform other work.

[0200] In addition, it should be noted that in the embodiment of the present disclosure, the gap between the two lifting mechanisms 111 is not limited. Specifically, it can be adapted according to the size of the transport trolley and the pallet 114.

[0201] On this basis, in the battery pack fastening system 1 in the embodiment of the present disclosure, in order to ensure that the positions of the transport trolley and the pallet 114 remain relatively fixed with the lifting mechanism 111 during the lifting of the pallet 114, a blocking assembly 112 can be used to limit the transport trolley.

[0202] For example, referring to Figures 8 and 9, a blocking member 1121 can be provided on the base 1111 that can extend between the two lifting mechanisms 111 relative to the base 1111 to limit the transport trolley. Specifically, a blocking assembly 112 can be provided at each end of the base 1111 along the transport path of the transport trolley. It should be noted that, referring to Figure 8, in some embodiments of the application, one blocking assembly 112 can be provided on one base 1111 and the other blocking assembly 112 can be provided on the other base 1111. In this way, when the transport trolley moves between the two lifting mechanisms 111 and needs to lift the pallet 114, the blocking members 1121 of the two blocking assemblies 112 extend into the transport path, thereby limiting the transport trolley. After the lifting mechanisms 111 complete lifting the pallet 114, the two blocking members 1121 withdraw from the transport path, thereby releasing the transport trolley from the limit and allowing the transport trolley to move to other workstations.

[0203] In the disclosed embodiment, a control module can be used to automatically control the sixth drive member 1122, causing the blocking assembly 112 to automatically limit or release the transport cart. For example, a position sensor can be provided on the lifting mechanism 111 to detect the position of the transport cart, tray 114, or battery pack. Furthermore, the control module can interlock the lifting signal of the lifting mechanism 111 with the movement of the sixth drive member 1122.

[0204] Thus, through the above arrangement, in the battery pack securing system 1 provided in the embodiment of the present disclosure, the number of jacking mechanisms 111 is set to two, and the gap between the two jacking mechanisms 111 can be used to form a transport path for the transport trolley, thereby matching the jacking mechanisms 111 with the characteristics of the battery pack production line. At the same time, by providing a blocking assembly 112 on the base 1111 of the jacking mechanism 111, the transport trolley can be limited between the jacking mechanisms 111, thereby ensuring that the jacking mechanism 111 can smoothly lift the tray 114 and the battery pack, thereby improving the reliability of the battery pack securing system 1 in the embodiment of the present disclosure.

[0205] On this basis, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, the lifting mechanism 111 further includes a locking assembly 113, which includes a locking member 1131 and a seventh driving member 1132. The seventh driving member 1132 can drive the locking member 1131 to move in a vertical direction to extend into a locking hole provided on the tray 114, thereby locking the tray 114 between the lifting mechanism 111. On this basis, the seventh driving member 1132 is also electrically connected to the control module, which can control the seventh driving member 1132 to drive the movement of the locking member 1131.

[0206] For example, referring to Figure 9 and Figure 11, in the embodiment of the present disclosure, the locking member 1131 can be set as a positioning pin, and a positioning hole is set on the tray 114 at the position corresponding to the positioning pin. After the lifting mechanism 111 completes lifting the tray 114, the positioning pin is lifted and extended into the positioning hole to position the tray 114, so as to avoid displacement of the tray 114 or the battery pack relative to the lifting mechanism 111 during the process of fastening or marking the battery pack by the fastening assembly 12.

[0207] In this way, in the battery pack fastening system 1 provided in the embodiment of the present disclosure, the locking assembly 113 can be used to position the tray 114 and the battery pack to prevent the tray 114 or the battery pack from being displaced relative to the lifting mechanism 111 during the process of fastening or marking the battery pack by the fastening assembly 12, thereby further improving the reliability of the battery pack fastening system 1 in the embodiment of the present disclosure.

[0208] On this basis, referring to FIG. 11 , the battery pack fastening system 1 in the embodiment of the present disclosure will be described below by taking the battery pack fastening system 1 in FIG. 11 as an example.

[0209] First, the transport trolley carrying the pallet 114 and the battery pack is transported from other workstations to the gap between the two lifting mechanisms 111 , and the control module determines that the transport trolley has been transported between the two lifting mechanisms 111 based on the position detection sensor provided on the lifting mechanism 111 .

[0210] Next, the control module controls the sixth driving member 1122 to drive the blocking member 1121 to extend into the gap between the two lifting mechanisms 111 , thereby limiting the transport trolley.

[0211] Furthermore, the control module controls the seventh driving member 1132 to drive the locking member 1131 to move in the vertical direction and extend into the locking hole on the tray 114, thereby positioning the tray 114. At this time, the control module can control the sixth driving member 1122 to retract, and the transport trolley can be driven to other stations for other work.

[0212] Next, the control module visually guides the driving assembly 13 based on the image of the fastener captured by the camera assembly 125 , and controls the fastening assembly 12 to move to a position above the fastener and close to the fastener.

[0213] The fourth drive member 1212 drives the fastening tool 1211 to engage the fastener and complete the tightening of the fastener. After the fastening assembly 12 completes the tightening of the previous fastener, the drive assembly 13 drives the fastening assembly 12 to move to the next fastener position and complete the tightening of the next fastener. This process is repeated to complete the tightening of all fasteners.

[0214] Then, the drive assembly 13 controls the fastening assembly 12 to move to the position of the clamping assembly 14. The control module controls the third drive member 142 to drive the clamping members 141 away from each other. After the drive assembly 13 or the second drive member 1222 drives the pen cap 12212 to be positioned between the clamping members 141, the third drive member 142 drives the clamping members 141 toward each other, clamping the pen cap 12212 between the clamping members 141.

[0215] Afterwards, the driving assembly 13 or the second driving member 1222 drives the marking pen 12211 to move in a direction away from the pen cap 12212 , so that the marking pen 12211 is separated from the pen cap 12212 .

[0216] On this basis, the fastening assembly 12 and the second driving member 1222 drive the marking tool 1221 to contact the corresponding fastener, completing the marking work of the corresponding fastener.

[0217] After this, the fastening assembly 12 or the second driving member 1222 drives the marking tool 1221 back to the position of the clamping assembly 14, so that the marking pen 12211 is inserted into the pen cap 12212. Then, the control module controls the third driving member 142 to drive the clamping members 141 away from each other, so that the clamping members 141 release the pen cap 12212. At this point, the fastening and marking work of the fastener is completed.

[0218] In addition, the present disclosure also provides a method for using a battery pack fastening system. The battery pack fastening system is used to fasten fasteners between a battery pack housing and an upper cover. The battery pack fastening system includes an operating platform, a fastening assembly, a marking assembly, and a camera assembly. Referring to FIG12 , FIG12 is a flow chart of a method for using a battery pack fastening system provided in an embodiment of the present disclosure. As shown in FIG12 , the method includes steps S11 to S15, wherein:

[0219] Step S11, placement step: placing the battery pack to be fastened on the operating platform;

[0220] Step S12, a fastening alignment step: causing the camera assembly to capture an image of the operating platform, and using the image to form a visual guide for the movement of the fastening assembly; based on the visual guide, causing the fastening assembly to move to a position where it docks with the fastener;

[0221] Step S13, a fastening step: enabling the fastening assembly to fasten the fastener;

[0222] Step S14, a marking alignment step: causing the camera assembly to capture an image of the operating platform, and using the image to form a visual guide for the movement of the marking assembly; based on the visual guidance, causing the marking assembly to move to a position where it docks with the fastener;

[0223] Step S15, marking step: the marking component is used to mark the fastener.

[0224] It should be noted that when understanding the method of using the battery pack fastening system provided in the embodiment of the present disclosure, reference can be made to the battery pack fastening system provided in the aforementioned embodiment for understanding.

[0225] In addition, in the embodiments of the present disclosure, the battery pack fastening system can be arranged at corresponding positions on the production line according to the production sequence of the battery packs, and the embodiments of the present disclosure are not limited to this. In addition, on the battery pack production line, the battery pack fastening system of the embodiments of the present disclosure can be arranged one, or two or more battery pack fastening systems can be arranged, and the embodiments of the present disclosure are not limited to this.

[0226] Here, in step S11, the battery pack may be transported to the operating platform by manual handling, conveyor belt transportation, or AGV transportation, which is not limited in the embodiment of the present disclosure.

[0227] For example, for transporting battery packs using AGV transportation, the control module of the battery pack fastening system can be used to obtain the signal that the AGC has reached the specified position. On this basis, the control module can control the battery pack fastening system to tighten the fasteners between the battery pack box and the upper cover according to the tightening task corresponding to the battery pack.

[0228] Specifically, in step S12, a camera assembly captures an image of the operating platform, including information about the position of the fastener. The control module analyzes the image to determine the position of the fastener to be tightened. Based on this information, the control module visually guides the movement of the fastening assembly based on the position of the fastener to be tightened, thereby controlling the fastening assembly to move to a position where it engages with the fastener. In this position, the fastening assembly engages the fastener and applies torque to the fastener, tightening the fastener.

[0229] During this process, the camera assembly can also be used to obtain the positions of the fasteners and the fastening assembly in real time, so that the control module can form dynamic visual guidance for the position of the fastening assembly.

[0230] On this basis, in step S13 , the fastener may be fastened using a fastening assembly.

[0231] It should be noted that in some embodiments of the present disclosure, a driver capable of rotating the fastener may be provided within the fastening assembly, and the position of the main structure of the fastening assembly does not change during the fastening process. Furthermore, for battery pack fastening systems equipped with a drive assembly, the drive assembly may also be used to rotate the fastener.

[0232] After the fasteners are tightened, they can be marked. It should be noted that all fasteners can be marked, or only specific fasteners can be marked, for example, fasteners that have been tightened can be marked, or fasteners that have failed the tightening result can be marked.

[0233] Continuing in step S14, the camera assembly captures an image of the operating platform, including the location information of the fastener to be marked. The control module analyzes the image to determine the location of the fastener to be marked. Based on this, the control module visually guides the movement of the marking assembly based on the location of the fastener to be marked, thereby controlling the marking assembly to move to the position corresponding to the fastener to be marked. In this position, the marking assembly corresponds to the fastener to be marked.

[0234] In step S15 , the marking assembly may be used to mark the fastener.

[0235] Specifically, in step S15, the fastener can be marked according to the marking method of the marking component. For example, if the marking component is configured to be similar to stamping a fastener, the marking component is configured to stamp the fastener. Alternatively, if the marking component is configured to be similar to marking a line with a marker pen, the marking component is configured to mark the fastener.

[0236] In the method for using the battery pack fastening system provided in the embodiment of the present disclosure, the image pictures obtained by the camera component are used to provide visual guidance for the movement of the fastening component and the marking component. It can be well adapted to battery packs of different models and specifications, as well as to fasteners in different positions of the battery pack, thereby increasing the scope of application of the battery pack fastening system and enabling it to be applied to the production of battery packs of different models and specifications.

[0237] On this basis, in some embodiments of the present disclosure, the fastening assembly and the marking assembly are further arranged to be relatively fixed, and the fastening assembly and the marking assembly are driven to move synchronously by the driving assembly.

[0238] Exemplarily, referring to FIG. 11 , the fastening assembly and the marking assembly may be mounted on the same connecting bracket, so that the fastening assembly and the marking assembly can remain relatively fixed.

[0239] In addition, referring to Figure 1, in some embodiments of the present disclosure, the drive assembly can be set as a six-axis robot. In addition, the drive assembly can also be set as other structures. The embodiments of the present disclosure are not limited to this, and reference can be made to the description of the drive assembly in the aforementioned embodiments.

[0240] Accordingly, in step S12, moving the fastening assembly to a position where the fastener is docked includes: moving the drive assembly to drive the fastening assembly to a position where the fastener is docked. In step S14, moving the marking assembly to a position where the fastener is docked includes: moving the drive assembly to drive the marking assembly to a position where the fastener is docked.

[0241] Here, the image picture at the operating platform obtained by the camera component can be used to form a visual guide for the movement of the drive assembly, so that the control module can be used to control the movement of the drive assembly so that the drive assembly can drive the fastening assembly to move to a position where it docks with the fastener, and the drive assembly can drive the marking assembly to move to a position where it docks with the fastener.

[0242] In this way, through the above arrangement, the fastening assembly and the marking assembly are set to be relatively fixed, and the driving assembly is used to synchronously drive the fastening assembly and the marking assembly to move, which can make the movement of the fastening assembly and the marking assembly simple and easy to achieve.

[0243] On this basis, in some embodiments of the present disclosure, the marking assembly includes a marking tool and a second driving member. The second driving member can drive the marking tool to move. Specifically, reference can be made to the description of the marking tool and the second driving member in the previous embodiment. Referring to Figure 13, the above-mentioned step S14 can be implemented through steps S141 to S142, wherein:

[0244] In step S141 , the camera assembly is configured to capture an image of the operating platform, and the image serves as a visual guide for the movement of the marking assembly; based on the visual guide, the marking assembly is moved to a position aligned with the fastener.

[0245] Step S142: The second driving member drives the marking tool to move to a position where the marking tool is docked with the fastener.

[0246] Specifically, in step S141, the camera assembly can capture an image of the operating platform, and the control module can process the image to determine the position of the fastener. Based on this, the image can be used to provide visual guidance for the movement of the marking assembly, thereby controlling the drive assembly to drive the marking assembly to a position aligned with the fastener.

[0247] It should be noted that the movement of the marking component here to the position aligned with the fastener refers to the position where the projection of the marking tool toward the fastener along the direction in which the marking tool is driven by the second driving member coincides with the fastener, and when the marking component is in the above-mentioned aligned position, the distance between the marking tool and the fastener is within the travel range of the second driving member.

[0248] Next, in step S142, when the fastening assembly is aligned with the fastener, the second driving member can drive the marking tool to engage with the fastener, thereby completing the marking of the fastener.

[0249] In this way, through the above arrangement, the second driving member can have only one degree of freedom, and the movement of the driving assembly and the movement of the second driving member can be made as simple as possible, so that the movement of the driving assembly and the movement of the second driving member are easy to control.

[0250] In addition, in some embodiments of the present disclosure, the fastening assembly includes a fastening tool and a fourth driving member, and the fourth driving member can drive the fastening tool to move. For details, reference can be made to the description of the fastening tool and the fourth driving member in the above embodiments. Referring to Figure 14, the above step S12 can be implemented through steps S121 to S122, wherein:

[0251] In step S121 , the camera assembly acquires an image of the operating platform, and the image provides visual guidance for the movement of the fastening assembly; based on the visual guidance, the fastening assembly is moved to a position aligned with the fastener.

[0252] Step S122: The fourth driving member drives the fastening tool to move to a position where the fastening tool docks with the fastener.

[0253] Specifically, in step S121, the camera assembly can capture an image of the operating platform, and the control module can process the image to determine the position of the fastener. Based on this, the image can be used to provide visual guidance for the movement of the fastening assembly, thereby controlling the drive assembly to drive the fastening assembly to move to a position aligned with the fastener.

[0254] It should be noted that the movement of the fastening assembly to the position aligned with the fastener here refers to the position where the projection of the fastening assembly toward the fastener along the direction in which the fastening tool is driven by the fourth driving member coincides with the fastener, and when the fastening assembly is in the above-mentioned aligned position, the distance between the fastening tool and the fastener is within the travel range of the fourth driving member.

[0255] Next, in step S122, when the fastening assembly is aligned with the fastener, the fourth driving member can drive the fastening tool to engage with the fastener, thereby completing the fastening of the fastener.

[0256] In this way, through the above arrangement, the fourth driving member can have only one degree of freedom, which can make the movement of the driving assembly and the movement of the fourth driving member as simple as possible, thereby making the movement of the driving assembly and the movement of the fourth driving member easy to control.

[0257] In some embodiments of the present disclosure, the marking tool includes a marking pen and a pen cap. The marking pen and the pen cap are detachably connected. For details, please refer to the description of the marking pen and the pen cap in the previous embodiments. The battery pack fastening system also includes a clamping assembly. The clamping assembly is capable of clamping or releasing the pen cap. For details, please refer to the description of the clamping assembly in the previous embodiments.

[0258] On this basis, before step S14, the method for using the battery pack fastening system in the embodiment of the present disclosure further includes:

[0259] Pen cap separation step: move the marking component to the clamping assembly, so that the clamping assembly clamps the pen cap, and the driving assembly drives the marking pen away from the pen cap to separate the marking pen and the pen cap.

[0260] Specifically, before the pen cap separation step, the battery pack fastening system may be in an idle state or in a state of fastening the fastener, in which the pen cap is covered on the marking pen. Before marking the fastener with the marking pen, the pen cap separation step needs to be performed.

[0261] Furthermore, during the pen cap separation step, the drive assembly can be controlled to move, causing it to drive the marking component to move toward the clamping assembly. Prior to this, the clamping assembly can be released, for example, by moving its clamping members away from each other. Subsequently, the pen cap can be controlled to move between the clamping members, causing the clamping assembly to clamp the pen cap. In this way, the clamping assembly secures the pen cap, preventing it from moving with the marking pen.

[0262] On this basis, the movement of the driving assembly can be controlled so that the driving assembly drives the marking pen away from the pen cap, thereby separating the marking pen and the pen cap.

[0263] Thus, in the method of using the battery pack fastening system provided by the embodiment of the present disclosure, the pen cap can be provided to protect the marker pen. Furthermore, the clamping assembly can be provided to clamp the pen cap, thereby facilitating separation of the pen cap and the marker pen.

[0264] On this basis, for the case where the marking tool includes a marking pen and a pen cap, and the battery pack fastening system includes a clamping assembly, the embodiment of the present disclosure further provides a method for using the battery pack fastening system. After the above step S15, the method further includes:

[0265] Pen cap engaging step: the driving assembly drives the marking pen to move to the pen cap clamped by the clamping assembly, and the driving assembly drives the marking pen to be inserted into the pen cap.

[0266] Pen cap releasing step: causing the clamping assembly to release the pen cap.

[0267] Here, after the marking pen finishes marking the fastener, the control module controls the drive assembly to move the marker to the pen cap held by the clamping assembly. Furthermore, the control module can further control the drive assembly or the second drive member to move to insert the marking pen into the pen cap.

[0268] Next, after the marker pen is inserted into the pen cap, the controller controls the clamping assembly to release the pen cap. This allows the pen cap to move with the marker pen to another position. For example, when the fastening assembly performs the next fastening operation, the pen cap, which is mounted on the marker pen, can move with the fastening assembly, thereby protecting the marker pen.

[0269] Through the above-mentioned setting, the state between the marking pen and the pen cap can be matched with the working state of the battery pack fastening system. On the premise that the function of the marking pen can be exerted, the pen cap can be used to protect the marking pen when the marking pen is not marking.

[0270] In addition, for transporting pallets and battery packs using an AGV, the operating platform in the disclosed embodiment includes two opposing lifting mechanisms, and a blocking assembly is provided between the lifting mechanisms. For details, please refer to the description of the lifting mechanisms and blocking assemblies in the aforementioned embodiment.

[0271] On this basis, the embodiment of the present disclosure further provides a method for using the battery pack fastening system. In the method, the above-mentioned step S11 can be implemented by the following steps:

[0272] Position limiting step: moving the transport trolley for transporting the pallet and the battery pack into the gap between the two lifting mechanisms, so that the blocking assembly limits the transport trolley between the lifting mechanisms;

[0273] Lifting step: enabling the lifting mechanism to lift the tray and the battery pack.

[0274] Here, the AGV can be guided by electromagnetic or optical guidance devices. This allows the AGC to carry the tray and battery pack along a predetermined route and into the gap between the two lifting mechanisms. Sensors can also be installed on the lifting mechanisms to monitor whether the AGC has reached the predetermined position between the two lifting mechanisms. For example, optical sensors can be used to monitor the position of the AGV.

[0275] On this basis, after the AGV moves to the gap between the two lifting mechanisms, the control module can be used to control the movement of the blocking assembly so that the blocking assembly extends into the gap between the two lifting mechanisms. In this way, the blocking assembly can limit the AGV between the two lifting mechanisms.

[0276] Next, the control module can be used to control the movement of the lifting mechanism, so that the lifting mechanism lifts the pallet and battery pack. This can separate the pallet from the AGV and bring the battery pack closer to the fastening assembly or marking assembly, shortening the movement of the drive assembly.

[0277] After that, the blocking component can release the limit on the AGV, and the AGV can move to other workstations to perform other work, such as transporting other pallets or battery packs.

[0278] In addition, in some embodiments of the present disclosure, a locking assembly is further provided on the lifting mechanism, which can keep the tray relatively fixed to the lifting mechanism. For details, please refer to the description of the locking assembly in the above embodiments.

[0279] To address this, an embodiment of the present disclosure further provides a method for using a battery pack fastening system. Between the above-mentioned lifting steps, the method further includes:

[0280] Locking step: extending the locking member of the locking assembly into the locking hole of the tray.

[0281] Here, when the lifting mechanism lifts the pallet, the control module can be used to control the locking assembly so that the locking part of the locking assembly extends into the locking hole of the pallet. In this way, the locking assembly can be used to limit the pallet, so that the pallet and the lifting mechanism remain relatively fixed, preventing the pallet from sliding during the lifting process.

[0282] It should be noted that in some embodiments of the present disclosure, a control module can be used to record the tightening results of the fasteners tightened by the fastening assembly; and a marking assembly can be used to mark fasteners with unqualified tightening results; and then, the fastening assembly can be used to re-tighten the fasteners marked by the marking assembly.

[0283] Here, a torque sensor or angle sensor can be installed in the fastening assembly to monitor the tightening results of the fastener to determine whether the torque applied to the fastener is acceptable. At the same time, a control module can be used to record the tightening results of the fastener. Based on this, the marking assembly can be controlled to mark fasteners with unacceptable tightening results.

[0284] In this way, after the marking component marks the fasteners with unqualified fastening results, it is possible to intuitively determine which fasteners have unqualified fastening results, thereby facilitating subsequent work.

[0285] On this basis, in some embodiments of the present disclosure, a fastening assembly may be used to re-tighten the fastener marked by the marking assembly.

[0286] Here, based on the above description, it can be understood that the fastener marked by the marking assembly is a fastener with an unqualified fastening result. In this case, the camera assembly can be used to determine the position of the marking mark applied by the marking assembly on the fastener. In this way, the control module can analyze the image of the fastener captured by the camera assembly to determine the position of the fastener with the marking mark. Based on this, the control module can control the movement of the drive assembly to drive the fastening assembly to move to the position corresponding to the fastener, thereby completing the re-tightening of the fastener.

[0287] Through the above-mentioned arrangement, the battery pack fastening system in the embodiment of the present disclosure can be used to re-tighten fasteners that failed the first tightening, thereby ensuring the assembly quality of the battery pack.

[0288] In some embodiments of the present disclosure, a fastener assembly can be used to pick up and install fasteners. Specifically, a fastener placement assembly can be arranged near the operating platform, with fasteners placed on the fastener placement assembly for the fastener assembly to pick up. The fastener assembly can then be used to pick up the fasteners and place them into the fastener installation holes of the battery pack.

[0289] Here, the fastener placement assembly can be set at any position near the operating platform. In the disclosed embodiment, the position where the fastener placement assembly is set near the operating platform is not limited, as long as the fastening component can pick up the fasteners on the fastener placement assembly.

[0290] In the disclosed embodiment, the fastener placement assembly can automatically load fasteners for the fastener assembly to pick up. Furthermore, in the disclosed embodiment, the method by which the fastener assembly picks up the fasteners is not limited; for example, the fastener assembly can pick up the fasteners through any method, such as magnetic attraction, grabbing, or clipping. Based on this, the control module can be used to control the movement of the drive assembly, causing the fastener assembly to place the fasteners into the fastener mounting holes of the battery pack.

[0291] In this way, through the above-mentioned settings, the degree of automation of the battery pack fastening system in the embodiment of the present disclosure can be further improved, making the battery pack fastening system in the embodiment of the present disclosure more intelligent.

[0292] In addition, in some embodiments of the present disclosure, the control module can be electrically connected to the display assembly, and the display assembly can be used to monitor the fastening process of the fastener by the fastening assembly, and the fastening result of the fastener can be displayed by the display assembly.

[0293] Here, a display screen can be used to create the display assembly in the disclosed embodiments. By electrically connecting the control module to the display screen, an interactive interface can be displayed on the display screen to facilitate control of the control module and the battery pack fastening system. Furthermore, the display screen can also be used to display images corresponding to the fastener tightening and marking process, thereby enabling better monitoring of the battery pack fastening system's fastener tightening and marking process.

[0294] In addition, the present disclosure also provides a method for producing a battery pack, which is used to fasten and mark the fasteners between the battery pack box and the upper cover using the battery pack fastening system provided in the above embodiment. FIG15 is a flowchart of the implementation of the battery pack production method provided in the embodiment of the present disclosure. As shown in FIG15 , the method includes steps S21 to S23, wherein:

[0295] Step S21, production step: producing the box body and upper cover of the battery pack;

[0296] Step S22, assembling step: placing the box body and the upper cover together in a corresponding assembly relationship;

[0297] Step S23, fastening step: using the battery pack fastening system to fasten the fasteners between the box body and the upper cover.

[0298] Here, the box body and the upper cover of the battery pack need to be fastened together by fasteners. For this, the box body and the upper cover can be produced in advance according to the production process of the box body and the upper cover.

[0299] On this basis, the box body and the upper cover can be placed together according to the assembly relationship using a grasping robot or manual operation. It should be noted that the assembly relationship between the box body and the upper cover here can be considered as the relative position relationship between the box body and the upper cover after assembly.

[0300] Finally, the battery pack fastening system provided in the aforementioned embodiment can be used to complete the fastening of the fasteners between the box body and the upper cover.

[0301] It should be noted that, for the fasteners between the battery pack housing and the upper cover, occasional factors may cause the torque applied by the battery pack fastening system to the fasteners to be unqualified. To address this situation, the application embodiment also provides a battery pack production method. Specifically, referring to Figure 16, in this production method, the above-mentioned step S23 can be implemented through steps S231 to S233, wherein:

[0302] Step S231, initial fastening step: using the battery pack fastening system to perform initial fastening on the fastener.

[0303] Step S232, a line marking step: using the battery pack fastening system to mark the fasteners whose initial fastening results are unqualified.

[0304] Step S233, final tightening step: tighten the marked fasteners again using the battery pack tightening system.

[0305] Here, a torque sensor can be provided in the fastening assembly to detect the torque applied by the fastening assembly to the fastener, so that the torque applied by the fastening assembly to the fastener can be compared with the torque required by the fastener, thereby determining the fastening result of the fastener after the initial fastening step is completed.

[0306] If after the initial tightening step is completed, the fasteners with unqualified initial tightening results are marked by a marking assembly, so that the fasteners with qualified initial tightening results can be distinguished from the fasteners with unqualified initial tightening results.

[0307] Illustratively, with reference to the description of the aforementioned embodiment, the marking component may include a marking pen, and the marking pen may be used to mark fasteners that have unqualified initial fastening results.

[0308] On this basis, the fastening components of the battery pack fastening system can be used to re-tighten the marked fasteners.

[0309] In this way, in the battery pack fastening method provided in the embodiment of the present disclosure, by using the battery pack fastening system to mark the fasteners whose initial fastening results are unqualified, and using the battery pack fastening system to re-tighten the fasteners whose initial fastening results are unqualified, the fastening quality of the battery pack can be improved and the reliability of the battery pack can be improved.

[0310] In addition, an embodiment of the present disclosure further provides a method for producing a battery pack. After the above-mentioned fastening step, the method further includes:

[0311] Recording the final tightening result of the fastener;

[0312] Transporting the battery pack with all the fasteners having qualified final fastening results to the next production process station;

[0313] Transporting the battery packs that fail the final fastening results of all the fasteners to a re-inspection station;

[0314] Here, the final tightening result of the fastener refers to the tightening result after the battery pack tightening system completes all tightening operations on the battery pack. For example, when the battery pack tightening system is used to re-tighten the fastener marked by the marking assembly, the final tightening result of the fastener refers to the tightening result after the fastener is re-tightened by the battery pack tightening system.

[0315] It should be noted that if all fasteners pass the initial tightening test in the initial tightening step, the battery pack can be transported to the next production process station. Alternatively, if a fastener fails the tightening test in the initial tightening step, but all fasteners pass the tightening test after the final tightening step, the battery pack can also be transported to the next production process station.

[0316] In contrast, if the fastening result of a fastener fails to meet the requirements in the initial fastening step and the fastening result of the fastener still fails to meet the requirements after the final fastening step, the battery pack is transported to a re-inspection station for re-inspection or manual tightening.

Industrial Applicability

[0318] In the battery pack fastening system provided by the embodiments of the present disclosure, a control module can process images of fasteners captured by the camera assembly to determine the position of the fasteners. Based on this, the control module can provide visual guidance for the movement of the drive assembly driving the fastening assembly, allowing the control module to control the drive assembly to move the fastening assembly to a position corresponding to the corresponding fastener. This allows the fastening assembly to mate with the corresponding fastener, allowing the fastening assembly to complete the fastening of the corresponding fastener. Furthermore, the control module can control the drive assembly to move the marking assembly to a position corresponding to the corresponding fastener. Based on this, the marking assembly can contact the corresponding fastener, allowing the marking assembly to complete the marking of the corresponding fastener. Furthermore, in the embodiments of the present disclosure, the control module controls the movement of the drive assembly or fastening assembly based on visual guidance provided by the images captured by the camera assembly. This allows for good adaptability to battery packs of different sizes and specifications, as well as to fasteners located in different locations within the battery packs. Therefore, the battery pack fastening system provided by the embodiments of the present disclosure can be applied to the production of battery packs of different sizes and specifications.
