[0003] In the production process of battery devices, multiple battery cells are typically stacked, with spacers placed between each pair of adjacent cells to form a battery cell assembly. However, in practical applications, the stacked size of the battery cell assembly often exceeds or falls short of the standard size, making it impossible to continue subsequent assembly processes and hindering the improvement of battery device production efficiency. Utility Model Content

[0004] The purpose of this application is to provide a battery pack assembly device and battery manufacturing equipment to solve the technical problem of low production efficiency of battery devices in related technologies.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is as follows: a battery assembly device is provided, including a first mechanism, a second mechanism, a third mechanism, and a fourth mechanism; the first mechanism is used to carry a plurality of battery cells arranged separately along a first direction; the second mechanism is used to detect the thickness of each battery cell located on the first mechanism along the first direction; the third mechanism has at least two storage areas, at least one storage area is used to store a separator of one thickness specification, and at least another storage area is used to store a separator of another thickness specification; the fourth mechanism is communicatively connected to the second mechanism, and the fourth mechanism is used to retrieve a separator from the corresponding storage area according to the thickness data of each battery cell located on the first mechanism, and the fourth mechanism is used to attach the separator to the surface of each battery cell located on the first mechanism along the first direction.

[0006] The battery pack assembly device provided in this application embodiment has at least the following beneficial effects: The second mechanism in the battery pack assembly device provided in this application embodiment can detect the thickness of each battery cell located on the first mechanism along the first direction, and the fourth mechanism is used to retrieve separators from the corresponding storage area according to the thickness data of each battery cell located on the first mechanism, and attach the separators to the surface of each battery cell located on the first mechanism along the first direction. In other words, based on the thickness of each battery cell located on the first mechanism detected by the second mechanism, the fourth mechanism can retrieve separators of the corresponding thickness specification from the corresponding storage area according to the thickness data of each battery cell located on the first mechanism, and attach the separators to the surface of each battery cell located on the first mechanism along the first direction. In this way, the thickness dimensions of each battery cell and the thickness dimensions of each separator can be accurately matched, thereby accurately controlling the stacking size of the battery cell assembly, effectively improving the situation where the stacking size of the battery cell assembly is greater than or less than the standard size, enabling the battery assembly process to proceed smoothly, and effectively improving the production efficiency of the battery device.

[0007] In some embodiments of this application, the battery pack assembly further includes a fifth mechanism for sequentially conveying multiple battery cells to a first mechanism so that the multiple battery cells are arranged separately on the first mechanism along a first direction, and a second mechanism for detecting the thickness of each battery cell during the process of conveying the battery cells by the fifth mechanism.

[0008] By adopting the above technical solution, the second mechanism can sequentially detect the thickness of each battery cell during the process of the fifth mechanism conveying the battery cells. This not only allows for accurate acquisition of the thickness data of each battery cell located on the first mechanism, but also enables simultaneous detection of the thickness of the battery cells during the conveying process, thereby further improving the production efficiency of the battery device.

[0009] In some embodiments of this application, the first mechanism includes a tray and a first driver, the fifth mechanism is used to sequentially transport multiple battery cells to the tray along a second direction, and the first driver is used to drive the tray to move along a first direction so that the multiple battery cells are arranged separately on the tray along the first direction, and the first direction and the second direction are perpendicular to each other.

[0010] By adopting the above technical solution, during the process of the fifth mechanism sequentially conveying multiple battery cells to the tray, the first driver can synchronously drive the tray to move along the first direction, so that the multiple battery cells are arranged separately on the tray along the first direction, thereby further improving the production efficiency of the battery device.

[0011] In some embodiments of this application, the battery pack assembly further includes a sixth mechanism, which is communicatively connected to the fifth mechanism and is used to detect the number of battery cells entering the first mechanism from the fifth mechanism.

[0012] By adopting the above technical solution, during the process of the fifth mechanism sequentially conveying multiple battery cells to the first mechanism, the sixth mechanism can detect the number of battery cells entering the first mechanism. When the number of battery cells entering the first mechanism reaches the preset number, the fifth mechanism can stop working to accurately control the number of battery cells entering the first mechanism, so that the assembly process of the battery device can proceed smoothly, thereby effectively improving the production efficiency of the battery device.

[0013] In some embodiments of this application, the first mechanism includes a tray, which includes a tray body and a stop. The tray body is used to carry multiple battery cells, and the stop is disposed on the tray body. The battery assembly device also includes a seventh mechanism, which includes a pressure member and a second driver. The second driver is used to drive the pressure member to move toward the tray so that the pressure member cooperates with the stop to clamp multiple battery cells.

[0014] By adopting the above technical solution, after the second driver drives the pressure member to move toward the tray, the pressure member can cooperate with the stop to clamp multiple battery cells to fix each battery cell so that the fourth mechanism can attach the separator to the surface of each battery cell located on the first mechanism along the first direction.

[0015] In some embodiments of this application, the fourth mechanism includes a picking member and a third driver. The picking member is used to pick up the isolation member, and the third driver is used to drive the picking member to reciprocate between the first mechanism and the third mechanism.

[0016] By adopting the above technical solution, it is convenient for the fourth mechanism to take out the separator in the storage area and attach the separator to the surface of each battery cell located on the first mechanism along the first direction.

[0017] In some embodiments of this application, the material handling component includes a first material handling part and a second material handling part, wherein the first material handling part is used to pick up one isolation component and the second material handling part is used to pick up another isolation component.

[0018] By adopting the above technical solution, the fourth mechanism can pick up at least two separators at the same time, reducing the number of times the fourth mechanism picks up materials, thereby further improving the production efficiency of the battery device.

[0019] In some embodiments of this application, the material taking component is a negative pressure adsorption component, and the fourth mechanism further includes a negative pressure generator, with the material taking component connected to the negative pressure generator pipeline.

[0020] By adopting the above technical solution, it is not only easier for the fourth mechanism to retrieve the isolation components in the storage area, but also the risk of damage to the isolation components during the process of the fourth mechanism retrieving the isolation components is effectively reduced.

[0021] In some embodiments of this application, the battery pack assembly includes an eighth mechanism, which is communicatively connected to the fourth mechanism and used to detect the position of each storage area.

[0022] By adopting the above technical solution, the fourth mechanism can accurately retrieve the separator in the corresponding storage area based on the position detection data of the eighth mechanism, thereby effectively improving the reliability of the battery pack assembly.

[0023] In some embodiments of this application, the eighth agency is a visual inspection agency.

[0024] By adopting the above technical solution, the visual inspection mechanism has high inspection accuracy, which enables the fourth mechanism to more accurately pick up the separator in the corresponding storage area, thereby further improving the reliability of the battery pack assembly.

[0025] In some embodiments of this application, the battery pack assembly includes a ninth mechanism that is communicatively connected to a fourth mechanism and is used to detect the position of each individual battery cell located on the first mechanism.

[0026] By adopting the above technical solution, the fourth mechanism can accurately attach the separator to the corresponding battery cell based on the position detection data of the ninth mechanism, thereby effectively improving the reliability of the battery pack assembly.

[0027] In some embodiments of this application, the ninth agency is a visual inspection agency.

[0028] By adopting the above technical solution, the visual inspection mechanism has high inspection accuracy, which enables the fourth mechanism to attach the separator to the corresponding battery cell more accurately, thereby further improving the reliability of the battery pack assembly.

[0029] In some embodiments of this application, the second agency is a visual inspection agency.

[0030] By adopting the above technical solution, the visual inspection mechanism has high inspection accuracy and can more accurately detect the thickness of battery cells. This allows for more accurate control of the stacking size of battery cell modules, further improving the situation where the stacking size of battery cell modules is greater than or less than the standard size. This enables the battery assembly process to proceed more smoothly and further improves the production efficiency of the battery device.

[0055] Battery devices are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with battery devices have been widely used, and battery devices are also being increasingly used in the field of energy storage.

[0056] In the production process of battery devices, multiple battery cells are usually stacked, and separators of appropriate thickness (such as heat insulation pads, insulating pads, etc.) are selected according to the model of the battery cells. Then, separators are set between each pair of adjacent battery cells to form a battery cell assembly.

[0057] However, in practical applications, due to the deviation in thickness of two or more battery cells of the same model, after setting up separators between each pair of adjacent battery cells, the final stacked size of the battery cell assembly is easily larger or smaller than the standard size, making it impossible for the battery cell assembly to be compatible with the battery box. This results in the inability to continue the battery boxing process, which is not conducive to improving the production efficiency of the battery device.

[0058] Based on the above considerations, in order to improve the production efficiency of battery devices, the second mechanism in the battery assembly device provided in this application embodiment can detect the thickness of each battery cell located on the first mechanism along the first direction. The fourth mechanism is used to retrieve separators from the corresponding storage area according to the thickness data of each battery cell located on the first mechanism, and attach the separators to the surface of each battery cell located on the first mechanism along the first direction. In other words, based on the thickness of each battery cell located on the first mechanism detected by the second mechanism, the fourth mechanism can retrieve separators of the corresponding thickness specifications from the corresponding storage area according to the thickness data of each battery cell located on the first mechanism, and attach the separators to the surface of each battery cell located on the first mechanism along the first direction. In this way, the thickness dimensions of each battery cell and the thickness dimensions of each separator can be accurately matched, thereby accurately controlling the stacking size of the battery cell assembly, effectively improving the situation where the stacking size of the battery cell assembly is greater than or less than the standard size, enabling the battery assembly process to proceed smoothly, and effectively improving the production efficiency of the battery device.

[0059] The battery packing apparatus provided in this application embodiment can be used in the battery packing process, that is, the process of stacking multiple battery cells to form a battery cell assembly.

[0060] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0061] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0062] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0063] In some embodiments, the battery device may be a battery pack, which includes a battery case and one or more individual battery cells housed within the battery case.

[0064] As an example, a battery cell assembly can be a battery module, which can be housed in a battery case by fixing the battery module in the battery case.

[0065] As an example, battery cell assemblies can also be housed in a battery box by directly fixing multiple battery cells to the battery box.

[0066] As an example, a battery cell can be a secondary battery, which refers to a battery cell that can be recharged after being discharged to activate the active materials and continue to be used.

[0067] The battery device provided in this application is applicable to various electrical devices that use individual battery cells, such as electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0068] The technical solutions provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0069] Firstly, please refer to the following: Figures 1 to 4This application provides a battery assembly device 100, including a first mechanism 10, a second mechanism 20, a third mechanism 30, and a fourth mechanism 40. The first mechanism 10 is used to carry a plurality of battery cells 200 arranged separately along a first direction. The second mechanism 20 is used to detect the thickness of each battery cell 200 located on the first mechanism 10 along the first direction. The third mechanism 30 has at least two storage areas 31, at least one storage area 31 is used to store a separator 300 of one thickness specification, and at least another storage area 31 is used to store a separator 300 of another thickness specification. The fourth mechanism 40 is communicatively connected to the second mechanism 20. The fourth mechanism 40 is used to retrieve the separator 300 from the corresponding storage area 31 according to the thickness data of each battery cell 200 located on the first mechanism 10, and the fourth mechanism 40 is used to attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction.

[0070] Understandably, multiple battery cells 200 are arranged separately along a first direction on the first mechanism 10. As an example, the fourth mechanism 40 can attach a spacer 300 to the surface of the battery cell 200 along the first direction within the gap between two adjacent battery cells 200.

[0071] In some embodiments, the first mechanism 10 includes a first base 13 and a tray 11 disposed on the first base 13, the tray 11 being used to carry a plurality of battery cells 200.

[0072] As an example, a clamping mechanism can be used to press against multiple battery cells 200 to secure the multiple battery cells 200 to the tray 11 so that the fourth mechanism 40 can attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction.

[0073] As an example, multiple limiting structures can be set on the tray 11, with each limiting structure corresponding to a multiple battery cell 200 to fix the multiple battery cells 200 on the tray 11, so that the fourth mechanism 40 can attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction.

[0074] The second mechanism 20 is used to detect the thickness of each battery cell 200 located on the first mechanism 10 along the first direction. Understandably, the second mechanism 20 can directly detect the thickness of each battery cell 200 located on the first mechanism 10, or it can detect the thickness of the battery cell 200 during the process of transporting the battery cell 200 to the first mechanism 10.

[0075] In some embodiments, the second mechanism 20 is a vision inspection mechanism. As an example, the second mechanism 20 is a CCD (Charge Coupled Device) inspection mechanism. The vision inspection mechanism has high inspection accuracy and can more accurately detect the thickness of the battery cell 200, thereby more accurately controlling the stacking size of the battery cell assembly. This further improves the situation where the stacking size of the battery cell assembly is larger or smaller than the standard size, making the battery assembly process smoother and further improving the production efficiency of the battery device.

[0076] Of course, in other embodiments, the second mechanism 20 can also be other mechanisms for thickness detection, such as a laser detection mechanism.

[0077] The third mechanism 30 is a mechanism for storing the separator 300. The third mechanism 30 has at least two storage areas 31, and the number of storage areas 31 can be determined according to actual application needs, specifically two, three, four, five, six, etc. Among them, at least one storage area 31 is used to store the separator 300 of one thickness specification, and at least another storage area 31 is used to store the separator 300 of another thickness specification.

[0078] As an example, the third mechanism 30 has two storage areas 31, one storage area 31 for storing a separator 300 of one thickness specification, and the other storage area 31 for storing a separator 300 of another thickness specification.

[0079] As an example, the third mechanism 30 has six storage areas 31, each containing a different thickness of the separator 300.

[0080] In some embodiments, the third mechanism 30 includes a second base 33 and at least two hoppers 32. The second base 33 has at least two storage areas 31. The at least two hoppers 32 are arranged in a one-to-one correspondence with the at least two storage areas 31. At least one hopper 32 is used to store a separator 300 of one thickness specification, and at least another hopper 32 is used to store a separator 300 of another thickness specification.

[0081] The fourth mechanism 40 is used to retrieve the separator 300 from the corresponding storage area 31 and attach the separator 300 to the surface of the battery cell 200 along the first direction. The fourth mechanism 40 is communicatively connected to the second mechanism 20, meaning that the fourth mechanism 40 can operate based on the thickness detection data of the second mechanism 20.

[0082] In some embodiments, the fourth mechanism 40 includes a picking member 41 and a third actuator 42. The picking member 41 is used to pick up the separator 300, and the third actuator 42 is used to drive the picking member 41 to reciprocate between the first mechanism 10 and the third mechanism 30. Understandably, when the third actuator 42 drives the picking member 41 to move to the corresponding storage area 31 of the third mechanism 30, the picking member 41 picks up the separator 300 within the storage area 31; when the third actuator 42 drives the picking member 41 to move to the first mechanism 10, the picking member 41 attaches the separator 300 to the surface of the corresponding battery cell 200 along a first direction. The picking member 41 can be, but is not limited to, a clamping member, an adsorption member, etc. The third actuator 42 can be, but is not limited to, a robotic arm, a multi-axis translation mechanism, etc.

[0083] In some embodiments, the battery assembly device 100 further includes a control mechanism, which is communicatively connected to the second mechanism 20 to receive thickness detection data from the second mechanism 20; the control mechanism is also communicatively connected to the fourth mechanism 40, which can calculate and analyze the thickness data from the second mechanism 20, and send an action command to the fourth mechanism 40 based on the analysis results, so that the fourth mechanism 40 can take out the separator 300 in the corresponding storage area 31 and attach the separator 300 to the surface of the battery cell 200 along the first direction according to the action command.

[0084] As an example, the second mechanism 20 is a visual inspection mechanism. The second mechanism 20 can also be used to detect the flatness of the surface of the battery cell 200 along the first direction and send the flatness data of the battery cell 200 to the control mechanism. The control mechanism can dynamically calculate the flatness data of the battery cell 200, so as to obtain the thickness data of the battery cell 200 more accurately.

[0085] In some embodiments, the separator 300 is a heat insulation component used to isolate the heat of two adjacent battery cells 200.

[0086] Of course, in other embodiments, the separator 300 may also be other components used to separate two adjacent battery cells 200, such as insulating components.

[0087] The second mechanism 20 in the battery assembly apparatus 100 provided in this application embodiment can detect the thickness of each battery cell 200 located on the first mechanism 10 along the first direction. The fourth mechanism 40 is used to retrieve the separator 300 from the corresponding storage area 31 according to the thickness data of each battery cell 200 located on the first mechanism 10, and attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction. In other words, based on the thickness of each battery cell 200 located on the first mechanism 10 detected by the second mechanism 20, the fourth mechanism 40 can retrieve the separator 300 of the corresponding thickness specification from the corresponding storage area 31 according to the thickness data of each battery cell 200 located on the first mechanism 10, and attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction. In this way, the thickness of each battery cell 200 can be accurately matched with the thickness of each separator 300, thereby accurately controlling the stacking size of the battery cell assembly. This effectively improves the situation where the stacking size of the battery cell assembly is greater than or less than the standard size, allowing the battery assembly process to proceed smoothly and effectively improving the production efficiency of the battery assembly.

[0088] In some embodiments of this application, please refer to Figure 1 The battery assembly device 100 also includes a fifth mechanism 50, which is used to sequentially transport multiple battery cells 200 to the first mechanism 10 so that the multiple battery cells 200 are arranged separately on the first mechanism 10 along a first direction. The second mechanism 20 is used to detect the thickness of each battery cell 200 during the process of transporting the battery cells 200 by the fifth mechanism 50.

[0089] The fifth mechanism 50 is used to transport the battery cells 200. The fifth mechanism 50 can be, but is not limited to, a belt conveyor mechanism, a roller conveyor mechanism, etc.

[0090] As an example, the second mechanism 20 is located on the side of the fifth mechanism 50. When the fifth mechanism 50 transports any battery cell 200 through the second mechanism 20, the second mechanism 20 detects the thickness of the battery cell 200.

[0091] By adopting the above technical solution, the second mechanism 20 can sequentially detect the thickness of each battery cell 200 during the process of the fifth mechanism 50 conveying the battery cells 200. This not only allows for accurate acquisition of the thickness data of each battery cell 200 located on the first mechanism 10, but also enables simultaneous detection of the thickness of the battery cells 200 during the conveying process, thereby further improving the production efficiency of the battery device.

[0092] Please refer to some embodiments of this application as well. Figure 1 and Figure 2 The first mechanism 10 includes a tray 11 and a first driver 12. The fifth mechanism 50 is used to sequentially transport multiple battery cells 200 to the tray 11 along the second direction. The first driver 12 is used to drive the tray 11 to move along the first direction so that the multiple battery cells 200 are arranged separately on the tray 11 along the first direction. The first direction and the second direction are perpendicular to each other.

[0093] The first direction and the second direction are set perpendicular to each other. As an example, the first direction can be the X direction as shown in the figure, and the second direction can be the Y direction as shown in the figure.

[0094] The first actuator 12 is used to drive the tray 11 to move along a first direction. The first actuator 12 can be, but is not limited to, a motor, an electric pneumatic cylinder, an electric hydraulic cylinder, etc.

[0095] In some embodiments, the first mechanism 10 further includes a first guide structure 14 extending along a first direction, and the tray 11 is movably mounted on the first guide structure 14.

[0096] As an example, the first guide structure 14 includes a first guide rail 141 and a first guide block 142. One of the first guide rail 141 and the first guide block 142 is disposed on the first base 13, and the other of the first guide rail 141 and the first guide block 142 is disposed on the tray 11. The first guide rail 141 extends along a first direction, and the first guide block 142 is slidably mounted on the first guide rail 141. During the process of the first driver 12 driving the tray 11 to move along the first direction, the first guide block 142 slides along the first guide rail 141 in the first direction, which can effectively improve the stability of the movement of the tray 11, thereby effectively improving the reliability of the battery assembly device 100.

[0097] Understandably, after the fifth mechanism 50 conveys the first battery cell 200 to the tray 11 along the second direction, the first driver 12 drives the tray 11 to move a preset distance along the first direction. Then, after the fifth mechanism 50 conveys the second battery cell 200 to the tray 11 along the second direction, the first driver 12 continues to drive the tray 11 to move a preset distance along the first direction. The distance that the first driver 12 drives the tray 11 to move along the first direction is equal each time. This cycle continues until the number of battery cells 200 on the tray 11 reaches a preset number, so that multiple battery cells 200 are arranged separately along the first direction on the tray 11.

[0098] By adopting the above technical solution, during the process of the fifth mechanism 50 sequentially conveying multiple battery cells 200 to the tray 11, the first driver 12 can synchronously drive the tray 11 to move along the first direction, so that the multiple battery cells 200 are arranged separately on the tray 11 along the first direction, thereby further improving the production efficiency of the battery device.

[0099] In some embodiments of this application, please refer to Figure 1 The battery pack assembly 100 also includes a sixth mechanism 60, which is communicatively connected to the fifth mechanism 50 and is used to detect the number of battery cells 200 entering the first mechanism 10 from the fifth mechanism 50.

[0100] The sixth mechanism 60 is used to detect the number of battery cells 200 entering the first mechanism 10 from the fifth mechanism 50. The sixth mechanism 60 can be, but is not limited to, a visual inspection mechanism, a through-beam photoelectric inspection mechanism, an infrared inspection mechanism, etc.

[0101] In some embodiments, the fifth mechanism 50 has an output end, the first mechanism 10 is disposed at the output end of the fifth mechanism 50, the fifth mechanism 50 can deliver the battery cell 200 from the output end to the first mechanism 10, and the detection end of the sixth mechanism 60 is disposed opposite to the output end of the fifth mechanism 50.

[0102] As an example, the sixth mechanism 60 is mounted on the first base 13 and the detection end of the sixth mechanism 60 is positioned opposite the output end of the fifth mechanism 50.

[0103] In some embodiments, the battery pack assembly 100 further includes a control mechanism, which is communicatively connected to a sixth mechanism 60 to receive detection data from the sixth mechanism 60; the control mechanism is also communicatively connected to a fifth mechanism 50, and when the sixth mechanism 60 detects that the number of battery cells 200 entering the first mechanism 10 reaches a preset number, the control mechanism can send a stop command to the fifth mechanism 50 to stop the fifth mechanism 50 from working.

[0104] By adopting the above technical solution, during the process of the fifth mechanism 50 sequentially conveying multiple battery cells 200 to the first mechanism 10, the sixth mechanism 60 can detect the number of battery cells 200 entering the first mechanism 10. When the number of battery cells 200 entering the first mechanism 10 reaches the preset number, the fifth mechanism 50 can stop working to accurately control the number of battery cells 200 entering the first mechanism 10, so that the battery assembly process can proceed smoothly, thereby effectively improving the production efficiency of the battery device.

[0105] Please refer to some embodiments of this application as well. Figure 2 and Figure 6The first mechanism 10 includes a tray 11, which includes a tray body 111 and a stop 112. The tray body 111 is used to carry multiple battery cells, and the stop 112 is disposed on the tray body 111. The battery assembly device 100 also includes a seventh mechanism 70, which includes a pressure member 71 and a second driver 72. The second driver 72 is used to drive the pressure member 71 to move toward the tray 11 so that the pressure member 71 cooperates with the stop 112 to clamp multiple battery cells.

[0106] In this embodiment, the second actuator 72 can drive the pressure-applying member 71 to move toward or away from the tray 11. The second actuator 72 can be, but is not limited to, a motor, an electric pneumatic cylinder, an electric hydraulic cylinder, etc.

[0107] Understandably, when the number of battery cells 200 on the tray 11 reaches a preset number, the second driver 72 drives the pressure member 71 to move toward the tray 11, so that the pressure member 71 cooperates with the stop 112 to clamp each battery cell 200 on the tray 11, so as to fix each battery cell 200 on the tray 11, so that the fourth mechanism 40 attaches the separator 300 to the surface of each battery cell 200 on the tray 11 along the first direction.

[0108] In some embodiments, the battery assembly device 100 further includes a fifth mechanism 50, a sixth mechanism 60, and a control mechanism. The fifth mechanism 50 is used to sequentially convey a plurality of battery cells 200 to the tray 11 along a second direction. The sixth mechanism 60 is used to detect the number of battery cells 200 entering the first mechanism 10 from the fifth mechanism 50. The fifth mechanism 50, the sixth mechanism 60, and the seventh mechanism 70 are all communicatively connected to the control mechanism. The first mechanism 10 further includes a first driver 12, which is used to drive the tray 11 to move along a first direction, which is perpendicular to the second direction. After the fifth mechanism 50 delivers the first battery cell 200 to the tray 11 along the second direction, the first driver 12 drives the tray 11 to move a preset distance along the first direction. Then, after the fifth mechanism 50 delivers the second battery cell 200 to the tray 11 along the second direction, the first driver 12 continues to drive the tray 11 to move a preset distance along the first direction. The distance that the first driver 12 drives the tray 11 to move along the first direction is equal each time. This cycle is repeated so that multiple battery cells 200 are arranged separately on the tray 11 along the first direction until the sixth mechanism 60 detects that the number of battery cells 200 entering the tray 11 has reached a preset number. At this time, the control mechanism can send a stop command to the fifth mechanism 50 to stop the fifth mechanism 50 from working. At the same time, the control mechanism can send an action command to the seventh mechanism 70 to drive the second driver 72 to drive the pressure member 71 to move towards the tray 11, so that the pressure member 71 cooperates with the stop 112 to clamp each battery cell 200 located on the tray 11, so as to fix each battery cell 200 on the tray 11, so that the fourth mechanism 40 attaches the separator 300 to the surface of each battery cell 200 located on the tray 11 along the first direction.

[0109] As an example, the seventh mechanism 70 also includes a third seat 73 and a second guide structure 74. The second guide structure 74 includes a second guide rail 741 and a second guide block 742. One of the second guide rail 741 and the second guide block 742 is disposed on the third seat 73, and the other of the second guide rail 741 and the second guide block 742 is disposed on the pressure member 71. The second guide rail 741 extends along a second direction, and the second guide block 742 is slidably mounted on the second guide rail 741. During the process of the second driver 72 driving the pressure member 71 to move along the second direction, the second guide block 742 slides along the second direction on the second guide rail 741, which can effectively improve the stability of the movement of the pressure member 71, thereby effectively improving the reliability of the battery assembly device 100.

[0110] By adopting the above technical solution, after the second driver 72 drives the pressure member 71 to move toward the tray 11, the pressure member 71 can cooperate with the stop 112 to clamp multiple battery cells to fix each battery cell 200 so that the fourth mechanism 40 can attach the separator 300 to the surface of each battery cell 200 located on the first mechanism 10 along the first direction.

[0117] In some embodiments, the eighth mechanism 80 is a vision inspection mechanism. As an example, the eighth mechanism 80 is a CCD (Charge Coupled Device) inspection mechanism. The vision inspection mechanism has high inspection accuracy, which enables the fourth mechanism 40 to more accurately pick up the separator 300 in the corresponding storage area 31, thereby further improving the reliability of the battery assembly device 100.

[0118] In some embodiments, the battery assembly device 100 further includes a control mechanism.

[0121] In some embodiments, the ninth mechanism 90 is a visual inspection mechanism. As an example, the ninth mechanism 90 is a CCD (Charge Coupled Device) inspection mechanism. The visual inspection mechanism has high inspection accuracy, which enables the fourth mechanism 40 to more accurately attach the separator 300 to the corresponding battery cell 200, thereby further improving the reliability of the battery pack assembly 100.

[0122] In some embodiments, the battery assembly 100 further includes an eighth mechanism 80 and a control mechanism.
