Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery cell transfer device and a battery production system. Background Technology

[0002] Battery devices are widely used in electronic devices such as mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools, etc.

[0003] During the production of battery devices, tested battery cells need to be transferred and stored. During this transfer, some battery cells still pose a risk of failure, and existing technologies struggle to effectively handle these failed cells during transport, leading to safety risks. Therefore, how to effectively handle failed battery cells during transport is a research direction in battery technology. Utility Model Content

[0004] This application provides a battery cell transfer device that can effectively handle failed battery cells during the transfer process.

[0005] In a first aspect, embodiments of this application provide a battery cell transfer device, including a processing cabinet, a temporary storage component, and a first temperature detection element. The processing cabinet has a receiving cavity and a first opening communicating with the receiving cavity. The temporary storage component is connected to the first opening and is used to receive battery cells. The temporary storage component has an openable and closable second opening for allowing the battery cells to enter the receiving cavity. The first temperature detection element is connected to the processing cabinet or the temporary storage component and is used to detect the temperature of the battery cells within the temporary storage component.

[0006] The battery cell transfer device employing the above technical solution includes a temporary storage component and a receiving cavity for disposing of failed battery cells. When the first temperature detector detects a high temperature in the battery cell within the temporary storage component, the control system or manual judgment determines that the battery is in a failed state. The second opening of the temporary storage component is then manually or automatically opened, allowing the failed battery cell to enter the receiving cavity for explosion-proof storage, instead of being directly transported to the next process. This effectively disposes of the failed battery cell and reduces the safety risks of subsequent processes. Furthermore, the integration of the traveling component, the disposal cabinet, and the temporary storage component simultaneously realizes the temporary storage, transportation, and disposal of failed battery cells.

[0007] In some embodiments of this application, the temporary storage component includes a temporary storage box and a switch driver. The temporary storage box is located at the first opening and has a second opening and a third opening for the battery cell to enter the temporary storage box. The second opening and the third opening are located on opposite sides or adjacent sides. The temporary storage box includes a first wall installed at the second opening. The switch driver is connected to the first wall and is used to drive the first wall to open or close the second opening.

[0008] The above technical solution is adopted to design the temporary storage component as including a temporary storage box and a switch driver. The switch driver is used to drive the first wall to open or close the second opening, thereby realizing the switching of the temporary storage component between the open and closed states. The structure is simple and the switch is convenient.

[0009] In some embodiments of this application, the first wall hinge is mounted on the temporary storage box, and the switch driver is used to drive the switch driver to rotate in order to open or close the second opening.

[0010] By adopting the above technical solution, the first wall is hinged to the temporary storage box, and the second opening is opened and closed by using a switch drive to rotate the first wall. The rotating first wall can effectively save the space inside the cavity and reduce the wear between the first wall and the temporary storage box during opening and closing.

[0011] In some embodiments of this application, the switch driver includes a motor.

[0012] By adopting the above technical solution, the first wall is driven to rotate by a motor. The rotation angle and speed of the motor can be controlled by programming to achieve precise opening and closing actions. Moreover, the motor has a long service life and low maintenance cost.

[0013] In some embodiments of this application, the first wall is slidably connected to the temporary storage box, and the switch driver is used to drive the first wall to move linearly to open or close the second opening.

[0014] By adopting the above technical solution, the first wall is slidably connected to the temporary storage box, and the first wall is driven to move linearly by the switch driver to open and close the second opening. This not only has a simple structure, but also allows for convenient control and adjustment of the size of the second opening.

[0015] In some embodiments of this application, the switch drive includes a pneumatic rod, an electric rod, or a hydraulic rod.

[0016] By employing the above technical solutions, using pneumatic, electric, or hydraulic rods to drive the first wall to slide, more precise control over the movement speed and position of the first wall can be achieved.

[0017] In some embodiments of this application, the first wall is the bottom wall of the temporary storage box.

[0018] By adopting the above technical solution, the first wall is designed as the bottom wall of the temporary storage box. When the second opening is opened, the battery cell can fall directly into the receiving cavity by its own gravity, without the need for other driving structures to make the battery cell enter the receiving cavity. The structure is ingenious.

[0019] In some embodiments of this application, the temporary storage box and the disposal cabinet are integrally connected.

[0020] By adopting the above technical solution, the temporary storage box and the disposal cabinet are connected as a whole, which improves the connection stability between the two.

[0021] In some embodiments of this application, the inner and / or outer walls of the treatment cabinet are connected to a heat insulation layer.

[0022] By adopting the above technical solution, the inner and / or outer walls of the treatment cabinet are provided with a heat insulation layer. After the failed battery cell enters the receiving cavity, the treatment cabinet can insulate it, reducing the risk of heat transfer to the rest of the battery cell transfer device and improving the safety during the transfer process.

[0023] In some embodiments of this application, the heat insulation layer includes a ceramic fiber layer.

[0024] By adopting the above technical solution, the ceramic fiber layer has excellent thermal insulation performance, chemical stability and fire resistance, making the disposal cabinet an explosion-proof structure.

[0025] In some embodiments of this application, the battery cell transfer device further includes a pickup component installed in the disposal cabinet and used to move the battery cell to the temporary storage component.

[0026] By adopting the above technical solution, a pick-up area is configured on the battery cell transfer device, and the battery cells are moved to the temporary storage component using the pick-up component. The battery cell pick-up, transfer and disposal of failed batteries are integrated through one device, reducing the occupation of production space in the workshop.

[0027] In some embodiments of this application, the picking component includes a picking mechanism, and the battery cell transfer device further includes a second temperature detection element, which is installed on the picking mechanism and used to detect the temperature of the battery cell picked up by the picking mechanism.

[0028] By adopting the above technical solution, a second temperature detection element is installed on the pickup mechanism of the pickup component. Both the second temperature detection element and the first temperature detection element can detect the temperature of the battery cell, thereby facilitating the determination of whether the battery cell has failed and improving the accuracy of the detection.

[0029] In some embodiments of this application, the picking mechanism includes a mounting member, a first gripper, and a second gripper. The first gripper and the second gripper are connected to the mounting member in a manner that allows them to move along a first direction, the first direction being the length direction of the mounting member. The second temperature sensor is mounted on the first gripper and / or the second gripper.

[0030] By adopting the above technical solution, the second temperature detection element is installed on the first gripper and / or the second gripper, so that the second temperature detection element can be closer to the battery cell picked up by the picking mechanism, thereby improving the accuracy of temperature detection.

[0031] In some embodiments of this application, the battery cell transfer device further includes an image acquisition component, which is mounted on the mounting component.

[0032] By adopting the above technical solution, the battery cell transfer device is designed to also include an image acquisition component. The image acquisition component is installed on the mounting component and used to acquire image information during the picking process of the picking component. This not only facilitates the picking operation of the picking component, but also enables the acquisition of images of surface defects of the battery cell.

[0033] In some embodiments of this application, the battery cell transfer device further includes a walking assembly, and the disposal cabinet is mounted on the walking assembly.

[0034] By adopting the above technical solution, the processing cabinet is driven to move by the walking component, which facilitates the transfer and transportation of battery cells by the battery cell transfer device.

[0035] Secondly, embodiments of this application provide a battery production system, including a battery cell transfer device as described in any of the above technical solutions. Attached Figure Description

[0066] The embodiments of this application will now be described in detail.

[0067] Currently, battery devices are being used more and more widely. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As the application areas of battery devices continue to expand, the market demand is also constantly increasing.

[0068] During the production of battery devices, their performance needs to be tested. After testing at the testing station, the battery cells are moved to the storage station by a transfer device for storage, so that the battery cells can be used for subsequent assembly and other processes.

[0069] The relevant technology typically involves a collaborative robot at the inspection station picking up individual battery cells and placing them onto a mobile transport vehicle. The mobile transport vehicle then transports the battery cells to the vicinity of the storage station, where a collaborative robot places the battery cells into the storage station.

[0070] The above-mentioned transfer process cannot effectively identify and handle failed battery cells. In particular, failed battery cells during the transfer process are easily transferred directly to the storage station for storage, which can easily damage the transfer device and storage equipment, as well as the remaining unfailed battery cells, posing certain safety risks.

[0071] Therefore, how to effectively handle failed batteries during transportation to reduce the safety risks of damaged transfer and storage devices by individual failed battery cells is an important issue in battery production and processing.

[0072] In view of this, this application provides a technical solution that designs a temporary storage component on the battery cell transfer device to temporarily store the battery cells, and uses a first temperature detection device to detect the temperature of the battery cells. When the temperature of the battery cell reaches the value of the failed battery cell, the failed battery cell is directly placed into the receiving cavity through the temporary storage component for disposal, thereby reducing the risk of the failed battery cell damaging the transfer device and storage equipment.

[0073] The following is in conjunction with the appendix Figure 1-8 The battery cell transfer device provided in the embodiments of this application will be described.

[0074] Combined with appendix Figure 1 and 2 As shown in the figure, this application provides a battery cell transfer device 100, including a processing cabinet 20, a temporary storage component 30, and a first temperature detection element 40. The processing cabinet 20 has a receiving cavity 21 and a first opening 22 communicating with the receiving cavity 21. The temporary storage component 30 is connected to the first opening 22 and is used to receive battery cells. The temporary storage component 30 has an openable and closable second opening 312 for allowing battery cells to enter the receiving cavity 21. The first temperature detection element 40 is connected to the processing cabinet 20 or the temporary storage component 30 and is used to detect the temperature of the battery cells in the temporary storage component 30.

[0075] The disposal cabinet 20 is mainly used to store failed battery cells. Its shape can be a rectangular box or other box structure, as long as it can meet the requirements for placing failed battery cells.

[0076] In some examples, a buffer structure 23 can be placed on the bottom plate inside the disposal cabinet 20. The buffer structure 23 can be an elastic flame-retardant material with a certain degree of deformability, or it can be fire sand directly laid on the bottom plate of the disposal cabinet 20. After the failed battery cell falls into the disposal cabinet 20, it can be wrapped and isolated by fire sand to further reduce safety risks.

[0077] The temporary storage component 30 is connected to the first opening 22. This can be understood as the temporary storage component 30 being connected to the wall of the treatment cabinet 20 surrounding the first opening 22. The temporary storage component 30 may be connected to the wall of the first opening 22 at its bottom. In this case, the second opening 312 can only be located at the bottom of the temporary storage component 30. Alternatively, the temporary storage component 30 may be partially or entirely located within the receiving cavity 21. In this case, the second opening 312 is provided on the side or bottom of the temporary storage component 30.

[0078] The temporary storage component 30 is mainly used to temporarily place battery cells. The temporary storage component 30 can hold one battery cell, so that the entire battery cell transfer device 100 transfers only one battery cell at a time, or it can hold multiple battery cells at the same time (this structure is not shown in the figure).

[0079] The temporary storage component 30 can operate between a closed state and an open state. In the closed state, the second opening 312 of the temporary storage component 30 is closed, and the temporary storage component 30 supports and fixes the battery cell. At this time, the battery cell cannot enter the receiving cavity 21.

[0080] In the open state, the second opening 312 of the temporary storage component 30 opens, allowing the battery cell to enter the receiving cavity 21 for processing. Then the second opening 312 closes again to prepare to receive the next battery cell.

[0081] The second opening 312 can be located at the bottom of the temporary storage component 30 along the horizontal direction X, or it can be located on the side of the temporary storage component 30 along the horizontal direction X. When the second opening 312 is located at the bottom of the temporary storage component 30 along the horizontal direction X, the battery cell can fall directly.

[0082] When the second opening 312 is located on the side of the temporary storage component 30 along the horizontal direction X, the failed battery cell can be removed from the second opening 312 by a structure such as a robot in the receiving cavity 21 and then placed into the receiving cavity 21 (this embodiment is not shown in the figure).

[0083] When the battery cell transfer device 100 transports one battery cell, the number of second openings 312 can be one. When the battery transfer device transports multiple battery cells at the same time, the number of second openings 312 can be one or more.

[0084] The first temperature detection element 40 is connected to the processing cabinet 20 or the temporary storage component 30, as long as it can detect the temperature of the individual battery cells in the temporary storage component 30.

[0085] The first temperature detection element 40 can be a temperature sensor, such as an infrared temperature sensor, a thermocouple sensor, a thermistor sensor, an IC temperature sensor, etc. This embodiment will not list them all.

[0086] The first temperature detection element 40 can be in direct contact with the battery cells in the temporary storage component 30, or be at a certain distance from the battery cells, and indirectly determine the temperature of the battery cells by detecting the ambient temperature inside the temporary storage component 30.

[0087] In some embodiments, the battery cell transfer device 100 of this embodiment may further include a control component. The control component may be communicatively connected to the aforementioned walking component 10, temporary storage component 30 and first temperature detection element 40 respectively. The control component may control the walking component 10 to walk and turn, and may also determine whether to open the second opening 312 by receiving temperature information detected by the first temperature detection element 40.

[0088] For example, when the first temperature detector 40 detects that the temperature of a battery cell is above 60°C, the control component determines that the battery cell is faulty, thereby opening the second opening 312 so that the battery cell can enter the receiving cavity 21 for processing, reducing the possibility that the faulty battery cell will affect the transfer device and directly enter the storage station.

[0089] The battery cell transfer device 100 with the above structure is provided with a temporary storage component 30 and a receiving cavity 21 for disposing of failed battery cells. When the first temperature detection element 40 detects that the temperature of the battery cell in the temporary storage component 30 is high, the control system or manual judgment determines that the battery is in a failed state, and the temporary storage component 30 is opened manually or automatically, so that the failed battery cell can enter the receiving cavity 21 through the second opening 312 for explosion-proof storage, instead of being directly transported to the next process. The failed battery cell is effectively disposed of, reducing the safety risks of subsequent processes.

[0090] In addition, the integration of the walking component 10, the handling cabinet 20 and the temporary storage component 30 simultaneously realizes the temporary storage, transportation and disposal of battery cells.

[0091] Combined with appendix Figure 3-6 As shown, in some examples, optionally, the temporary storage component 30 includes a temporary storage box 31 and a switch driver 32. The temporary storage box 31 is located at a first opening 22 and has a second opening 312 and a third opening 313 for battery cells to enter the temporary storage box 31. The second opening 312 and the third opening 313 are located on adjacent or opposite sides. The temporary storage box 31 includes a first wall 311 installed in the second opening 312. The switch driver 32 is connected to the first wall 311 and is used to drive the first wall 311 to open or close the second opening 312.

[0092] The temporary storage box 31 can be a rectangular box structure, or it can be a cylindrical shell, etc. The specific shape can match the shape of the battery cell. This embodiment will not list too many examples.

[0093] The temporary storage box 31 may have a third opening 313 at the upper end along the horizontal direction X, so as to facilitate the entry of the battery cell. Alternatively, the third opening 313 may be designed to be openable and closable through the top cover (this embodiment is not shown in the figure). The top cover is opened before the battery cell enters the temporary storage box 31, so that the battery cell can enter through the third opening 313. The top cover is closed when the battery is transferred to protect the battery cell during the transfer process.

[0094] The first wall 311 can be part or all of the bottom wall of the battery cell, or part or all of the side wall of the battery cell. The first wall 311 closing the second opening 312 means that the second opening 312 can be completely or partially closed. The size of the second opening 312 is greater than or equal to a certain cross-sectional size of the battery cell (e.g., cross-section or longitudinal section), so that the battery cell can be allowed to enter the receiving cavity 21 when the first wall 311 opens the second opening 312.

[0095] The switch drive unit 32 is a drive structure used to drive the first wall 311 to open and close the second opening 312. The specific structure is given below.

[0096] In this embodiment, the temporary storage component 30 is designed to include a temporary storage box 31 and a switch driver 32. The switch driver 32 drives the first wall 311 to open or close the second opening 312, thereby realizing the switching of the temporary storage component 30 between the open and closed states. The structure is simple and the switch is convenient.

[0097] Combined with appendix Figure 3 and attached Figure 4 As shown, in some examples, optionally, the first wall 311 is hinged to the temporary storage box 31, and the switch drive 32 is used to drive the switch drive 32 to rotate in order to open or close the second opening 312.

[0098] The first wall 311 can be hinged to the temporary storage box 31 via the first hinge shaft, so that the first wall 311 can rotate relative to the temporary storage box 31. Figure 3 and Figure 4 The state in.

[0099] In the first wall 311 Figure 3 When the battery cell is in the storage box 31, the first wall 311 closes the second opening 312, so that the battery cell can be stably located in the storage box 31, thereby enabling the transportation of the battery cell.

[0100] In the first wall 311 Figure 4 When the battery cell is in the "failure" state, the control component determines that the battery cell has failed. The first wall 311 opens the second opening 312, allowing the battery cell to enter the receiving cavity 21 under its own weight or with the assistance of a robotic arm. Subsequently, the first wall 311 is reset to its original position via the switch drive 32. Figure 3 The state in.

[0101] The first wall 311 is hinged to the temporary storage box 31, and the first wall 311 is rotated to open and close the second opening 312. The rotating first wall 311 can effectively save the space inside the receiving cavity 21 and reduce the wear between the first wall 311 and the temporary storage box 31 during opening and closing.

[0102] In some examples, the switch driver 32 may optionally include a motor 321.

[0103] The first wall 311 is rotated by the motor 321. The rotation angle and speed of the motor 321 can be controlled by programming to achieve precise opening and closing actions. Moreover, the motor 321 has the advantages of long service life and low maintenance cost.

[0104] Of course, in addition to the motor 321, the switch drive unit 32 in this embodiment can also be a hydraulic motor, pneumatic motor or other structure that can output torque. This embodiment will not list them all.

[0105] In addition, the motor 321 can also be connected to the aforementioned first hinge shaft via a transmission structure such as gears to achieve a speed change function.

[0106] Combined with appendix Figure 5 and attached Figure 6 As shown, in some examples, optionally, the first wall 311 is slidably connected to the temporary storage box 31, and the switch drive 32 is used to drive the first wall 311 to move linearly to open or close the second opening 312.

[0107] The sliding connection refers to the fact that the first wall 311 can slide on the temporary storage box 31 in a certain direction (such as the vertical direction Y in the figure) to open and close the second opening 312.

[0108] The first wall 311 is slidably connected to the temporary storage box 31. The first wall 311 is driven to move linearly by the switch driver 32 to open and close the second opening 312. This not only has a simple structure, but also allows for easy control and adjustment of the size of the second opening 312.

[0109] A socket 314 or a matching structure such as a plug can be provided on the temporary storage box 31. Taking the socket 314 as an example, when the first wall 311 closes the second opening 312, the first wall 311 is inserted into the socket 314 of the temporary storage box 31. The socket 314 provides auxiliary support for the temporary storage box 31. Combined with the supporting and fixing function of the switch drive component 32, the stability of the first wall 311 can be improved.

[0110] When the first wall 311 opens the second opening 312, the first wall 311 disengages from one or more insertion holes 314, allowing the failed battery cell to enter the receiving cavity 21.

[0111] In some examples, the switch actuator 32 may optionally include a pneumatic rod 322, an electric rod, or a hydraulic rod.

[0112] The pneumatic rod 322 is a device that uses compressed air to generate push and pull force to achieve linear motion. The pneumatic rod 322 is typically composed of a cylinder, a piston, and seals. By controlling the inlet and outlet of the air source, the piston reciprocates within the cylinder, thereby driving the movement of the first wall 311.

[0113] An electric rod (not shown in the figure) is a device that achieves linear motion by driving a screw or chain transmission system with an electric motor.

[0114] A hydraulic rod (not shown in the figure) is a device that uses the flow and pressure of a liquid (usually oil) to generate pushing and pulling forces, achieving linear motion. A hydraulic rod consists of a hydraulic cylinder, piston, seals, and a hydraulic valve, controlling the linear movement of the piston by controlling the inflow and outflow of the liquid.

[0115] Taking the pneumatic rod 322 in the figure as an example, it includes the cylinder 3221 and the piston rod 3222 in the figure. By using the linear motion of the piston rod 3222 on the cylinder 3221 to drive the first wall 311 to slide, more precise control of the movement speed and position of the first wall 311 can be achieved.

[0116] Combined with appendix Figure 3-6 As shown, in some examples, the first wall 311 may optionally be the bottom wall of the temporary storage box 31.

[0117] When the first wall 311 is the bottom wall, it can be connected to the side wall of the temporary storage box 31 in the manner described above, either by hinge or sliding connection.

[0118] When the second opening 312 is opened, the battery cell can fall directly into the receiving cavity 21 by its own gravity, without the need for other driving structures to make the battery cell enter the receiving cavity 21, which is ingenious.

[0119] In some examples, the temporary storage box 31 and the disposal cabinet 20 are optionally connected as a single unit.

[0120] Integrated connection refers to the temporary storage box 31 being connected to the wall at the opening of the treatment cabinet 20 as a whole through mechanical connection methods such as welding, bolting, and bonding. It can also refer to the temporary storage box 31 and the treatment cabinet 20 being integrally processed and formed by molds or bending processes.

[0121] The temporary storage box 31 and the treatment cabinet 20 are connected as a whole, which can improve the connection strength between the temporary storage box 31 and the treatment cabinet 20 and improve the connection stability of the two.

[0122] Of course, the connection method between the temporary storage box 31 and the disposal cabinet 20 in this embodiment is not limited to this. For example, the two can also be connected and fixed together by plugging, riveting, etc., as long as the required connection strength can be designed. This embodiment will not list them one by one.

[0123] Combined with appendix Figure 7 As shown, in some examples, optionally, the inner and / or outer walls of the treatment cabinet 20 are connected to an insulation layer 241.

[0124] The treatment cabinet 20 includes multiple panels 24. Taking the box-shaped treatment cabinet 20 in the figure as an example, it includes four side panels 24, a top panel 24 and a bottom panel 24. The multiple panels 24 form a receiving cavity 21.

[0125] The inner and / or outer walls of the treatment cabinet 20 are connected to a heat insulation layer 241. This technical solution includes three implementation methods: one is that the inner wall of each panel 24 of the treatment cabinet 20 is covered with a heat insulation layer 241; another is that the outer wall of each panel 24 of the treatment cabinet 20 is covered with a heat insulation layer 241; and the third is as follows... Figure 7 The inner and outer walls of each panel 24 of the treatment cabinet 20 shown are covered with a heat insulation layer 241.

[0126] The size of the heat insulation layer 241 can be the same as the size of the panel 24 it is connected to. After the failed battery cell enters the receiving cavity 21, the disposal cabinet 20 with the heat insulation layer 241 can insulate it, reducing the risk of heat transfer to the rest of the battery cell transfer device 100 and improving the safety during the transfer process.

[0127] In some examples, the insulation layer 241 may optionally include a ceramic fiber layer 2411.

[0128] The ceramic fiber layer 2411 can be an aluminosilicate ceramic fiber layer 2411, or it can be a zirconia ceramic fiber layer 2411, a silicon carbide ceramic fiber layer 2411, etc.

[0129] The ceramic fiber layer 2411 has excellent thermal insulation, chemical stability and fire resistance, which makes the disposal cabinet 20 form an explosion-proof structure.

[0130] Of course, the material of the insulation layer 241 in this embodiment is not limited to this, and can also be insulation materials such as rock wool and glass wool.

[0131] Combined again with the appendix Figure 1 As shown, in some examples, the battery cell transfer device 100 may optionally include a pick-up assembly 50, which is mounted on the disposal cabinet 20 and used to move the battery cells to the temporary storage assembly 30.

[0132] In some embodiments, the picking component 50 can be understood as having a structure that grasps and moves the battery cells, such as a mechanical gripper, a vacuum suction cup, or a pneumatic clamp.

[0133] In related technologies, picking components 50 are usually set up at both the testing station and the storage station of battery cells. However, in this embodiment, the picking component 50 is directly integrated into the battery cell transfer device 100. The picking component 50 is used to move the battery cells to the temporary storage component 30. The picking, transfer and disposal of failed batteries are integrated through one device, reducing the occupation of production space in the workshop.

[0134] In some examples, optionally, the picking component 50 of this embodiment includes a picking mechanism 51, and the battery cell transfer device 100 further includes a second temperature detection element 60, which is installed on the picking mechanism 51 and used to detect the temperature of the battery cell picked up by the picking mechanism 51.

[0135] The pickup assembly 50 may also include a moving mechanism 52 for moving the pickup mechanism 51. The moving mechanism 52 may include a robotic arm, which is a mechanical device that can simulate the movement of a human arm. It typically consists of multiple joints 522 and connecting parts, and can achieve multi-axis movement and precise control.

[0136] In some embodiments, the robotic arm may include a base 521, a joint 522, and an actuator (not shown). The base 521 is mounted on the top of the treatment cabinet 20. The joint 522 is the movable part connecting the robotic arm, enabling rotational or translational movement. The actuator includes components such as a motor 321 and a hydraulic cylinder that control the movement of the robotic arm, driving its motion.

[0137] The actuators of the robotic arm can be controlled by the aforementioned control components, or by their own control unit.

[0138] The robotic arm can drive the picking mechanism 51 to move along the horizontal direction X and the vertical direction Y. The structure of the robotic arm will not be described in detail in this embodiment.

[0139] In some embodiments, the picking component 50 can be understood as the end effector of a robotic arm, which may be a gripper, suction cup, or other structure, to pick up individual battery cells.

[0140] The second temperature sensor 60 has the same or similar structure as the first temperature sensor 40 mentioned above, and can also be connected to the control component mentioned above.

[0141] Both the second temperature detection element 60 and the first temperature detection element 40 can detect the temperature of the battery cells, thereby facilitating the control assembly to know and determine whether the battery cells have failed and improving the accuracy of the detection.

[0142] Combined with appendix Figure 8 As shown, in some examples, the picking mechanism 51 optionally includes a mounting member 511, a first gripper 512 and a second gripper 513, the first gripper 512 and the second gripper 513 being connected to the mounting member 511 in a manner movable along a first direction, the first direction being the length direction of the mounting member 511, and a second temperature detection member 60 being mounted on the first gripper 512 and / or the second gripper 513.

[0143] The above technical solution also includes three implementation methods, one of which is as follows: Figure 8 The figure shows two different implementations: one where the second temperature sensor 60 is installed only on the first jaw 512, another where the second temperature sensor 60 is installed only on the second jaw 513, and yet another where the second temperature sensor 60 is installed on both the first jaw 512 and the second jaw 513. The latter two implementations are not shown in the figure.

[0144] In some embodiments, the first direction can be the horizontal direction X. In addition, the first direction can also be the vertical direction Y, or any other direction that intersects the horizontal direction X and the vertical direction Y.

[0145] When the first gripper 512 and the second gripper 513 are gripping a battery cell, the second temperature detection element 60 can get closer to or directly adhere to the battery cell picked up by the picking mechanism 51, thereby improving the accuracy of temperature detection.

[0146] In some examples, the battery cell transfer device 100 may optionally include an image acquisition component 70, which is mounted on the mounting component 511.

[0147] The image acquisition component 70 can be an image acquisition structure such as a camera, scanner, etc. The image acquisition component 70 converts light into electrical signals through a lens to generate image information.

[0148] The image acquisition component 70 can be communicatively connected to the aforementioned control component. In this embodiment, "communicative connection" refers to a connection via a line or wireless signal.

[0149] The control component can manipulate the pickup component 50 based on image information, which not only facilitates the pickup component 50 in pickup operations, but also enables the acquisition of images of surface defects on battery cells.

[0150] In some examples, the battery cell transfer device 100 may optionally include a walking assembly 10, to which the disposal cabinet 20 is mounted.

[0151] The walking component 10 drives the processing cabinet 20 to move, facilitating the transfer and transportation of battery cells by the battery cell transfer device 100.

[0152] The walking component 10 can be understood as the structure that drives the processing cabinet 20 and the temporary storage component 30 to move. It can be any kind of walking structure such as wheels, tracks, or bionic legs.

[0153] In some embodiments, the walking assembly 10 can be a walking vehicle structure, which includes a vehicle body 11 and a drive structure, transmission steering wheel, electronic control structure, radar and touch screen located within the vehicle body 11 (other components besides the vehicle body 11 are not shown in the figure).

[0154] The vehicle body 11 has wheels, and the drive structure, transmission structure, and wheels are sequentially connected to each other, thereby enabling the vehicle body 11 to move. In this embodiment, the treatment cabinet 20 can be directly installed on the top of the vehicle body 11.

[0155] The electronic control structure is connected to components such as radar, touch screen, drive structure, and transmission steering wheel to receive radar signals and control the rotation of the drive structure and the direction of the transmission structure. The drive structure can be a component that outputs torque, such as an electric motor.

[0156] In addition, the aforementioned vehicle body 11, drive structure, transmission steering wheel, electronic control structure, radar and touch screen can also be explosion-proofed, for example, by using explosion-proof, flame-retardant and heat-insulating materials for each component, or by coating them with explosion-proof, flame-retardant and heat-insulating coatings.

[0157] Of course, the specific structural form of the walking component 10 in this embodiment is not limited to this. As long as it can drive the processing cabinet 20 and the temporary storage component 30 from the battery cell testing station to the storage station, this embodiment will not list them one by one.
