Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery device testing system and testing method. 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, safety performance testing is required using testing equipment. After testing, the battery devices are left to cool naturally in the testing equipment before they can be taken out for the next batch of testing, which reduces the utilization rate of the testing equipment. Therefore, how to improve the utilization rate of testing equipment is a research direction in battery technology. Summary of the Invention

[0004] This application provides a battery device testing system and testing method, which can improve the utilization rate of testing equipment.

[0005] In a first aspect, embodiments of this application provide a battery device testing system, including a testing device, a static storage device, and a transfer device. The testing device is used to perform mechanical performance testing on the battery device, and the static storage device is used to place the battery device. The transfer device is used to remove the battery device that has not been cooled after testing by the testing device and place the battery device in the static storage device for cooling.

[0006] By adopting the above technical solution, the battery device testing system is designed to include testing equipment, static storage equipment, and a transfer device. After the testing equipment has tested the current batch of battery devices, the transferred device can place the tested battery devices into the static storage equipment for cooling. This allows the testing equipment to perform performance testing on the next batch of battery devices. Compared with the original method of waiting for the battery devices on the testing equipment to cool naturally before testing the next batch, this method can effectively improve the utilization rate of the testing equipment, shorten the testing time for multiple batches of battery devices, and improve testing efficiency.

[0007] In some embodiments of this application, the static storage device is provided with a first temperature detection element, which is used to detect the temperature of the battery device located in the static storage device.

[0008] By adopting the above technical solution, the static storage device is configured with a first temperature detection element, which can be used to detect the temperature of the battery device. When the temperature of the battery device reaches the failure temperature, the battery device can be subjected to failure treatment.

[0009] In some embodiments of this application, the static storage device is provided with multiple storage spaces, and at least one of the first temperature detection elements is installed in each storage space.

[0010] By adopting the above technical solution, the static storage device is designed to include multiple storage spaces to hold multiple battery devices, which can meet the cooling and storage requirements of multiple battery devices. Furthermore, by using multiple first temperature detection devices to perform one-to-one testing on the battery devices in each storage space, the accuracy of the testing can be improved.

[0011] In some embodiments of this application, the static storage device includes a storage platform, a first partition and a second partition. The first partition and the second partition intersect and are both installed on the storage platform. The first partition, the second partition and the storage platform enclose a plurality of storage spaces, and the storage platform is provided with receiving slots located in each of the storage spaces.

[0012] By adopting the above technical solution, the storage equipment is designed to include a storage platform, a first partition and a second partition. The storage platform, the first partition and the second partition form multiple storage spaces. This not only has a simple structure, but also the enclosed storage spaces have multiple openings, which facilitates the transfer device to pick up and put in the battery device.

[0013] In some embodiments of this application, the transfer device includes a transfer body and a second temperature detection element mounted on the transfer body, the second temperature detection element being used to detect the temperature of the battery device located on the transfer device.

[0014] By adopting the above technical solution, the transfer device is configured with a second temperature detection element, which can be used to detect the temperature of the battery device during the transfer process. When the temperature of the battery device reaches the failure temperature, the battery device can be handled by the transfer device.

[0015] In some embodiments of this application, the transport body includes a walking assembly, a treatment cabinet, and a temporary storage assembly. The treatment cabinet is installed on the walking assembly and has a receiving cavity and a first opening communicating with the receiving cavity. The temporary storage assembly is connected to the first opening and is used to store the battery device during transport. The temporary storage assembly has an openable and closable second opening for the battery device to enter the receiving cavity. A second temperature detection element is connected to the treatment cabinet or the temporary storage assembly and is used to detect the temperature of the battery device inside the temporary storage assembly.

[0016] Using the above technical solution, when the second temperature detection device detects that the battery device in the temporary storage component is at a high temperature, the control device or manual judgment indicates that the battery is in a failed state. The second opening of the temporary storage component is then opened manually or automatically, allowing the failed battery device to enter the receiving cavity for temporary storage instead of being directly transported to the unloading area. This effectively handles the failed battery device and reduces the safety risks of subsequent processes.

[0017] 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 device 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 in 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.

[0018] 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.

[0019] In some embodiments of this application, the first wall is hinged to 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; or, 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 in order to open or close the second opening.

[0020] Using the above technical solution, the first wall is hinged to the temporary storage box. A switch driver is used to rotate the first wall to open and close the second opening. The rotating first wall effectively saves space inside the storage cavity and reduces wear between the first wall and the temporary storage box during opening and closing. Alternatively, the first wall can be slidably connected to the temporary storage box, and a switch driver can be used to move the first wall linearly to open and close the second opening. This not only simplifies the structure but also allows for easy control and adjustment of the size of the second opening.

[0021] In some embodiments of this application, the first wall is the bottom wall of the temporary storage box.

[0022] 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 device can fall directly into the receiving cavity by its own gravity, without the need for other driving structures to make the battery device enter the receiving cavity. The structure is ingenious.

[0023] In some embodiments of this application, the transfer unit further includes a pickup component installed in the disposal cabinet and used to move the battery device to the temporary storage component.

[0024] By adopting the above technical solution, a pick-up area is configured on the transfer device, and the battery device is moved to the temporary storage component using the pick-up component. The battery device pick-up, transfer and disposal of failed batteries are integrated through a single device, reducing the occupation of production space in the workshop.

[0025] In some embodiments of this application, the pickup assembly includes a pickup mechanism, and the transfer device further includes a third temperature sensor mounted on the pickup mechanism and used to detect the temperature of the battery device on the pickup mechanism.

[0026] By adopting the above technical solution, a third temperature detection element is installed on the pickup mechanism of the pickup component. Both the third temperature detection element and the second temperature detection element can detect the temperature of the battery device, thereby facilitating the determination of whether the battery device has failed and improving the accuracy of the detection.

[0027] In some embodiments of this application, the battery device detection system further includes a failure handling device, and the transfer device is configured to move the battery device with a temperature greater than or equal to the failure temperature to the failure handling device.

[0028] By adopting the above technical solution and configuring failure handling equipment, the transfer device can move battery devices that have failed as detected by the detection equipment, battery devices that have failed as detected by the static storage equipment, and battery devices that have failed as detected during the transfer process to the failure handling equipment for storage, thereby reducing safety risks.

[0029] Secondly, this application provides a battery device testing method, which uses the battery device testing system described in any of the above technical solutions. The battery device testing method includes the following steps: placing the battery device in a testing device for mechanical performance testing; removing the tested battery device from the testing device and placing it in a static storage device for cooling; and transferring the cooled battery device from the static storage device to the unloading area.

[0030] By adopting the above technical solution, after the testing equipment has tested the current batch of battery devices, the tested battery devices can be placed in a static storage device to cool down, so that the testing equipment can perform performance testing on the next batch of battery devices. Compared with the original method of waiting for the battery devices on the testing equipment to cool down naturally before testing the next batch, this method can effectively improve the utilization rate of the testing equipment, shorten the testing time for multiple batches of battery devices, and improve testing efficiency.

[0031] In some embodiments of this application, the battery device testing method further includes: performing failure detection on the battery device on the testing equipment, wherein the failure detection includes detecting at least one parameter among the internal resistance, voltage, temperature and capacity of the battery device, and determining whether the detected parameter meets the failure standard; and performing failure processing on the battery device that is determined to be failed.

[0032] By adopting the above technical solution, the battery devices that fail to be detected by the testing equipment are processed to reduce the possibility of the failed battery devices entering the unloading area for storage, thereby reducing safety risks.

[0033] In some embodiments of this application, the battery device detection method further includes: performing temperature detection on the battery device in the static storage device and determining whether the battery device has reached the failure temperature; and performing failure processing on the battery device that has reached the failure temperature.

[0034] By adopting the above technical solution, the temperature of the battery device is detected during the static cooling process. When the temperature of the battery device reaches the failure temperature, the battery device can be disposed of, further reducing the possibility of the failed battery device entering the subsequent material processing process and reducing safety risks.

[0035] In some embodiments of this application, the battery device detection method further includes: performing temperature detection on the battery device transferred from the static storage device to the unloading area, and determining whether the battery device has reached the failure temperature; and performing failure processing on the battery device that has reached the failure temperature.

[0036] By adopting the above technical solution, the temperature of the battery device is detected during the transfer process. When the temperature of the battery device reaches the failure temperature, the battery device can be disposed of, further reducing the possibility of the failed battery device entering the subsequent material handling process and reducing safety risks.

[0071] The embodiments of this application will now be described in detail.

[0072] 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.

[0073] During the production process of battery devices, the performance of the battery devices needs to be tested by testing equipment. The testing equipment can be a compression testing equipment. After the testing is completed, the battery devices remain in the testing equipment for natural cooling. After cooling, the battery devices are removed from the testing equipment and then the next batch of battery devices is tested.

[0074] This testing method means that the testing equipment remains occupied even after the compression test, preventing it from testing the next batch of battery devices. This reduces the utilization rate of the equipment and consequently lowers the overall testing efficiency.

[0075] Therefore, improving the utilization rate of testing equipment to reduce the safety risks of failed battery devices damaging transfer and storage devices is an important issue in battery production and processing.

[0076] In view of this, this application provides a battery device testing system and testing method, which promptly removes the battery device after testing and cools it in a static storage device, so that the testing equipment can be used to test the next batch of battery devices, thereby improving the utilization rate of the testing equipment.

[0077] The following is in conjunction with the appendix Figure 1-11 This application provides a battery device testing system and testing method according to embodiments.

[0078] Combined with appendix Figure 1 As shown, this embodiment provides a battery device testing system 1000, including a testing device 200, a static storage device 300, and a transfer device 100. The testing device 200 is used to test the mechanical properties of the battery device, and the static storage device 300 is used to place the battery device. The transfer device 100 is used to remove the battery device that has not been cooled after testing by the testing device 200 and place the battery device in the static storage device 300 for cooling.

[0079] The testing device 200 can be an extrusion testing device 200, which includes an extrusion device, a detection structure for detecting the resistance of the battery device, a detection structure for detecting the temperature of the battery device, and a processing structure for data processing and analysis (the above structures are not shown in the figure).

[0080] A battery device may consist of a single battery cell or a battery cell module consisting of multiple battery cells.

[0081] The extrusion testing equipment 200 extrudes the battery device and then tests parameters such as resistance, temperature, voltage, and mechanical properties. The state of the battery device is reflected by these parameters, thereby determining whether the battery device has failed. The specific testing process and principle can be found in relevant technologies, which will not be described in detail in this embodiment.

[0082] The static storage device 300 is used to place battery devices that have not cooled down after testing. It can hold one or more battery devices. The static storage device 300 can be a frame structure or a platform structure, etc.

[0083] In some embodiments, cooling structures such as air cooling and water cooling (not shown in the figure) can also be provided on the static storage device to improve the cooling rate of the battery device.

[0084] The transfer device 100 is used to pick up and put down the battery device and drive the battery device to move between the testing device 200, the static storage device 300 and the unloading station. The unloading station may be equipped with an unloading device 800 for storing the battery device. Optional embodiments of the structure of the transfer device 100 are given below.

[0085] In this embodiment, the battery device testing system 1000 is designed to include a testing device 200, a static storage device 300, and a transfer device 100. After the testing device 200 tests the current batch of battery devices, the transfer device 100 can place the tested battery devices (one or more) into the static storage device 300 for cooling. This allows the testing device 200 to perform performance testing on the next batch of battery devices (one or more). Compared to the original method of waiting for the battery devices on the testing device 200 to cool naturally before testing the next batch, this method can effectively improve the utilization rate of the testing device 200, shorten the testing time for multiple batches of battery devices, and improve testing efficiency.

[0086] Combined with appendix Figure 2 As shown, in some examples, optionally, the static storage device 300 is provided with a first temperature detection element 310 for detecting the temperature of the battery device located in the static storage device 300.

[0087] The first temperature detection element 310 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.

[0088] When the first temperature detection element 310 detects that the temperature of the battery device has reached the failure temperature, the operation of the transfer device 100 can be controlled by the control device 400 or manually to move the failed battery device to the failure processing equipment 500 at the failure processing station for explosion-proof processing, thereby reducing safety risks.

[0089] Regarding the "failure temperature" in this embodiment, it can be understood as the temperature reached on the outer surface of the battery device when its performance degrades or it fails completely due to structural or material damage. This temperature is usually closely related to the battery's chemical composition, construction, and environmental conditions (such as humidity, airflow, etc.).

[0090] Batteries from different manufacturers and models may differ in design and materials, thus affecting their failure temperature. Taking lithium-ion batteries as an example, when the temperature of the outer surface is detected to be greater than or equal to 60°C, it can be determined that the battery device is at its failure temperature and there is a possibility of internal failure.

[0091] In some examples, the static storage device 300 may optionally have a plurality of storage spaces 350, each storage space 350 having at least one first temperature sensing element 310 installed therein.

[0092] The storage space 350 can be understood as having multiple tanks or chambers, each of which is open at least at one end, thus facilitating the transfer device 100 to pick up and put in the battery device.

[0093] The storage space has multiple 350 cubic meters, which can simultaneously store multiple battery devices for cooling, thus meeting the cooling and storage requirements of multiple battery devices.

[0094] Furthermore, since the multiple storage spaces 350 are independent of each other, the battery devices in each storage space 350 can be tested one-to-one using multiple first temperature detection devices 310, which can improve the accuracy of temperature detection of individual battery devices.

[0095] In some examples, the static storage device 300 optionally includes a storage platform 320, a first partition 330 and a second partition 340, the first partition 330 and the second partition 340 intersect and are both installed on the storage platform 320, the first partition 330, the second partition 340 and the storage platform 320 enclose a plurality of the storage spaces 350, and the storage platform 320 is provided with a receiving slot 3201 located in each storage space 350.

[0096] The storage platform 320 may include a platform structure and a base frame. The platform structure is mounted on the base frame to meet the height requirements of the platform structure and to cooperate with the storage device of this embodiment.

[0097] The storage platform 320 has a storage surface, which is the flat surface at the top of the storage platform 320. The first partition 330 and the second partition 340 are installed on the storage surface by means of mechanical connection such as bolts or welding.

[0098] The first partition 330 and the second partition 340 intersect each other, and the minimum angle between them is greater than 0 degrees and less than or equal to 90 degrees. In some embodiments, the first partition 330 and the second partition 340 can be perpendicular to each other and enclose four storage spaces 350, each storage space 350 having multiple openings to facilitate the transfer device 100 in taking out and placing the battery device.

[0099] The storage platform 320 is provided with at least one receiving slot 3201 in each storage space 350. The receiving slot 3201 is used to place the battery device, thereby improving the stability of the battery device when it is stationary and cooling. In this embodiment, the first temperature detection element 310 can be installed inside or outside the receiving slot 3201.

[0100] Of course, the structure of the static storage device 300 in this embodiment is not limited to this. Other structures that can statically store battery devices are also within the scope of this embodiment, such as frame structures.

[0101] Combined with appendix Figure 3 As shown, in some examples, the transfer device 100 may optionally include a transfer body and a second temperature detection element 40 mounted on the transfer body, the second temperature detection element 40 being used to detect the temperature of the battery device located on the transfer device 100.

[0102] The transporter can move the battery device, for example, it can be a vehicle body 11 structure, and alternative embodiments of the transporter are given below.

[0103] The second 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.

[0104] The second temperature detection element 40 has the same or similar structure as the first temperature detection element 310 mentioned above. Therefore, this embodiment will not describe its principle and structure in detail.

[0105] The transfer device 100 is configured to have a second temperature detection element 40, which can be used to detect the temperature of the battery device during the transfer process. When the temperature of the battery device reaches the failure temperature, the battery device can be handled by the transfer device 100.

[0106] Combined with appendix Figure 3 and 4As shown, in some examples, optionally, the transport body includes a walking assembly 10, a treatment cabinet 20, and a temporary storage assembly 30. The treatment cabinet 20 is mounted on the walking assembly 10 and has a receiving cavity 21 and a first opening 22 communicating with the receiving cavity 21. The temporary storage assembly 30 is connected to the first opening 22 and is used to store the battery device during transport. The temporary storage assembly 30 has an openable and closable second opening 312 for the battery device to enter the receiving cavity 21. A second temperature detection element 40 is connected to the treatment cabinet 20 or the temporary storage assembly 30 and is used to detect the temperature of the battery device inside the temporary storage assembly 30.

[0107] 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.

[0108] 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).

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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 device detection station to the storage station, this embodiment will not list them one by one.

[0113] The disposal cabinet 20 is mainly used to store failed battery devices. Its shape can be a rectangular box or other box structure, as long as it can meet the requirements for placing failed battery devices.

[0114] 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 laid directly on the bottom plate of the disposal cabinet 20. After the failed battery device falls into the disposal cabinet 20, it can be wrapped and isolated by fire sand to further reduce safety risks.

[0115] 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.

[0116] The temporary storage component 30 is mainly used for temporarily placing the battery device. The temporary storage component 30 can hold one battery device, so that the entire transfer device 100 transfers only one battery device at a time, or it can hold multiple battery devices at the same time (this structure is not shown in the figure).

[0117] 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 device. At this time, the battery device cannot enter the receiving cavity 21.

[0118] In the open state, the second opening 312 of the temporary storage component 30 opens, allowing the battery device to enter the receiving cavity 21 for processing. Subsequently, the second opening 312 closes again to prepare to receive the next battery device.

[0119] The second opening 312 can be located at the bottom of the temporary storage component 30 along the horizontal direction X, or at 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 single device can be dropped directly.

[0120] When the second opening 312 is located on the side of the temporary storage component 30 along the horizontal direction X, the failed battery device 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).

[0121] When the transfer device 100 transports one battery device, the number of second openings 312 can be one. When the battery transfer device 100 transports multiple battery devices at the same time, the number of second openings 312 can be one or more.

[0122] The second 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 battery device inside the temporary storage component 30.

[0123] The second temperature detection element 40 can be in direct contact with the battery device inside the temporary storage component 30, or be at a certain distance from the battery device, and indirectly determine the temperature of the battery device by detecting the ambient temperature inside the temporary storage component 30.

[0124] When the second temperature detector 40 detects that the battery device inside the temporary storage component 30 is at a high temperature, the control device 400 or a person determines that the battery is in a failed state. The second opening 312 of the temporary storage component 30 is then opened manually or automatically, allowing the failed battery device to enter the receiving cavity 21 through the second opening 312 for temporary storage, instead of being directly transported to the unloading area. This effectively handles the failed battery device and reduces the safety risks of subsequent processes.

[0125] In addition, the integration of the walking component 10, the handling cabinet 20 and the temporary storage component 30 simultaneously enables the temporary storage, transportation and disposal of battery devices that have failed.

[0126] In some embodiments of this application, 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 the battery device to enter the temporary storage box 31. The second opening 312 and the third opening 313 are located on opposite sides or adjacent 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.

[0127] 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 device. This embodiment will not list too many examples.

[0128] The temporary storage box 31 may have a third opening 313 at the upper end along the horizontal direction XX, so as to facilitate the entry of the battery device. 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 device enters the temporary storage box 31, so that the battery device can enter through the third opening 313. The top cover is closed when the battery is transferred to protect the battery device during the transfer process.

[0129] The first wall 311 may be part or all of the bottom wall of the battery device, or part or all of the side wall of the battery device. 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 (e.g., cross-section or longitudinal section) of the battery device, so that the battery device can be allowed to enter the receiving cavity 21 when the first wall 311 opens the second opening 312.

[0130] 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.

[0131] 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.

[0132] Combined with appendix Figure 5-8 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, so as to open or close the second opening 312; or, 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, so as to open or close the second opening 312.

[0133] 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 5 and Figure 6 The state in.

[0134] In the first wall 311 Figure 5 When the battery is in the storage box 31, the first wall 311 closes the second opening 312, so that the battery device can be stably located in the storage box 31, thereby enabling the transport of the battery device.

[0135] In the first wall 311 Figure 6 When the battery device is in a certain state, the control device 400 can determine that the battery device has failed. The first wall 311 opens the second opening 312, allowing the battery device to enter the receiving cavity 21 under its own weight or with the assistance of a robotic arm. Then, the first wall 311 is reset to its original position by the switch drive 32. Figure 5 The state in.

[0136] 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.

[0137] In some embodiments, the switch driver 32 includes a motor 321.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] Combined with appendix Figure 7 and attached Figure 8 As shown, the sliding connection means that the first wall 311 can slide on the temporary storage box 31 in a certain direction (such as the vertical direction YY in the figure) to open and close the second opening 312.

[0142] 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.

[0143] 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.

[0144] 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 device to enter the receiving cavity 21.

[0145] In some embodiments, the switch drive 32 includes a pneumatic rod 322, an electric rod, or a hydraulic rod.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] In some embodiments of this application, the first wall 311 is the bottom wall of the temporary storage box 31.

[0151] 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.

[0152] When the second opening 312 is opened, the battery device can fall directly into the receiving cavity 21 by its own gravity, without the need for other drive structures to make the battery device enter the receiving cavity 21, which is ingenious.

[0153] In some examples, the temporary storage box 31 and the disposal cabinet 20 are optionally connected as a single unit.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] Combined with appendix Figure 9As shown, in some embodiments, the inner and / or outer walls of the treatment cabinet 20 are connected to a heat insulation layer 241.

[0158] 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.

[0159] 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 9 The inner and outer walls of each panel 24 of the treatment cabinet 20 shown are covered with a heat insulation layer 241.

[0160] The size of the insulation layer 241 can be the same as the size of the panel 24 to which it is connected. After the failed battery device enters the receiving cavity 21, the disposal cabinet 20 with the insulation layer 241 can insulate it, reducing the risk of heat transfer to the rest of the transfer device 100 and improving the safety during the transfer process.

[0161] In some embodiments, the insulation layer 241 includes a ceramic fiber layer 2411.

[0162] The thermal insulation layer 241 includes a ceramic fiber layer 2411, which can be understood as at least a portion of the thermal insulation layer 241 being made of ceramic fiber material, or the thermal insulation layer 241 including one or more layers, at least one of which is a ceramic fiber layer 2411.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] Combined again with the appendix Figure 3 As shown, in some examples, the transfer unit may optionally include a pick-up assembly 50, which is mounted on the disposal cabinet 20 and used to move the battery device to the temporary storage assembly 30.

[0167] In some embodiments, the picking component 50 can be understood as having a structure that grips the battery device and moves the battery device, such as a mechanical gripper, a vacuum suction cup, a pneumatic clamp, etc.

[0168] In related technologies, pick-up components 50 are usually set up at both the testing station and the storage station of the battery device. However, in this embodiment, the pick-up component 50 is directly integrated into the transfer device 100. The pick-up component 50 is used to move the battery device to the temporary storage component 30. The pick-up, transfer and disposal of failed batteries are integrated through one device, reducing the occupation of production space in the workshop.

[0169] In some examples, optionally, the pickup component 50 of this embodiment includes a pickup mechanism 51, and the transfer device 100 further includes a third temperature detector 60, which is mounted on the pickup mechanism 51 and used to detect the temperature of the battery device picked up by the pickup mechanism 51.

[0170] 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.

[0171] 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.

[0172] The actuators of the robotic arm can be controlled by the control device 400 described below, or by its own control unit.

[0173] 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.

[0174] 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 the battery device.

[0175] The third temperature sensor 60 has the same or similar structure as the aforementioned second temperature sensor 40, and can also be connected in communication with the control device 400 described below.

[0176] Both the third temperature sensor 60 and the second temperature sensor 40 can detect the temperature of the battery device, thereby facilitating the control device 400 to detect and determine whether the battery device has failed, and improving the accuracy of the detection.

[0177] Combined with appendix Figure 10As shown, in some embodiments, the picking mechanism 51 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 third temperature detection member 60 being mounted on the first gripper 512 and / or the second gripper 513.

[0178] The above technical solution also includes three implementation methods, one of which is as follows: Figure 10 The figure shows three different implementations: one where the third temperature sensor 60 is installed only on the first jaw 512; another where the third temperature sensor 60 is installed only on the second jaw 513; and yet another where the third 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.

[0179] 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.

[0180] When the first gripper 512 and the second gripper 513 are gripping the battery device, the third temperature detection element 60 can get closer to or directly adhere to the battery device picked up by the picking mechanism 51, thereby improving the accuracy of temperature detection.

[0181] In one embodiment, the transfer device 100 further includes an image acquisition component 70, which is mounted on the mounting member 511.

[0182] 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.

[0183] The image acquisition component 70 can be communicatively connected to the control device 400 described below. In this embodiment, "communicative connection" refers to a connection via a line or wireless signal.

[0184] The control device 400 can operate 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 of the battery device.

[0185] Combined again with the appendix Figure 1 As shown, in some examples, the battery device detection system 1000 may optionally include a failure handling device 500, and the transfer device 100 is configured to move battery devices with a temperature greater than or equal to the failure temperature to the failure handling device 500.

[0186] The failure handling device 500 can be an explosion-proof box or other structure capable of storing battery devices. The structure of the failure handling device 500 can be the same as or similar to that of the disposal cabinet 20, but its size is larger than that of the disposal cabinet 20.

[0187] The above technical solution includes a failure handling device 500. The transfer device 100 can move battery devices detected by the detection device 200 and the static storage device 300 to the failure handling device 500. It can also move battery devices in the disposal cabinet 20 to the failure handling device 500. The failure battery devices in the disposal cabinet 20 can be placed in the failure handling device 500 for storage with the assistance of manual labor or a robotic arm, thereby reducing safety risks.

[0188] In some embodiments, the battery device detection system 1000 further includes a control device 400, which is communicatively connected to the transfer device 100.

[0189] The control device 400 may include a processor or control circuit such as a PLC or MCU. The control device 400 may be directly or indirectly connected to the aforementioned detection device 200, walking component 10, pickup component 50, first temperature detection element 310, second temperature detection element 40 and third temperature detection element 60, so as to determine whether the battery is in a failed state.

[0190] In some embodiments, the control device 400 can control the walking component 10 to walk and turn, and can also determine whether to open the second opening 312 by receiving temperature information detected by the second temperature detector 40 and the third temperature detector 60, and determine whether to place the battery device in the static storage device 300 into the failed device by receiving temperature information detected by the first temperature detector 310, and can also determine whether to place the battery device that has not cooled after detection directly into the failed device by receiving parameters detected by the detection device 200.

[0191] For example, when the second temperature sensor 40 detects that the temperature of the battery device is above 60°C, the control component determines that the battery device has failed, thereby opening the second opening 312 so that the battery device can enter the receiving cavity 21 for disposal, reducing the possibility that the failed battery device will affect the transfer device 100 and directly enter the storage station.

[0192] The control device 400 can be an independent machine structure, or a portion of the control device 400 can be installed on the transfer device 100 to form a control assembly for controlling the transfer device 100 and receiving and processing signals. The control device 400 may also have a display interface to facilitate operation of the transfer device 100 by staff.

[0193] Combined again with the appendix Figure 1 As shown, in some embodiments, the battery device detection system 1000 may further include a loading device 600 located in the material handling area and a charging device 700 located in the charging area. The transfer device 100 can transport the battery device in the loading device 600 to the detection device 200 for detection, and can be charged by the charging device 700 and standby in the charging area.

[0194] Combined with appendix Figure 11 As shown, based on the battery device testing system 1000 described above, this application embodiment provides a battery device testing method, which includes the following steps:

[0195] The battery device is placed in the testing equipment 200 for mechanical performance testing;

[0196] After testing, the battery device is removed from the testing equipment 200 and placed in the static storage equipment 300 for cooling; the cooled battery device is then transferred from the static storage equipment 300 to the unloading area.

[0197] The battery device can be placed into the testing equipment 200 by the aforementioned transfer device 100. Specifically, the transfer device 100 can directly transfer the battery device in the loading device 600 to the testing equipment 200.

[0198] After testing by the testing equipment 200, the uncooled battery devices are taken out again by the transfer device 100 and placed in the static storage device 300. After cooling time, the non-failed battery devices are placed in the unloading device 800 in the unloading area for storage.

[0199] The above process can be controlled by the control device 400 of this embodiment, or manually controlled by the operation interface of the control device 400.

[0200] Compared to the original method of allowing the battery devices on the testing equipment 200 to cool naturally before the next batch is tested, this method can effectively improve the utilization rate of the testing equipment 200, shorten the testing time for multiple batches of battery devices, and improve testing efficiency.

[0201] In some examples, the battery device detection method may optionally include:

[0202] Failure detection is performed on the battery device on the testing equipment 200. The failure detection includes testing at least one parameter among the internal resistance, voltage, temperature and capacity of the battery device, and determining whether the detected parameter meets the failure standard.

[0203] The battery device that is determined to be faulty will be processed for failure.

[0204] The parameters for the compression detection of the battery device can be one or more of the internal resistance, voltage, temperature and capacity listed above, and of course, other parameters can also be included. The specific detection principle of the compression detection can be referred to the relevant technology, which will not be described in detail in this embodiment.

[0205] Failure processing of battery devices detected by the testing equipment 200 can be carried out by the transfer device 100. This method reduces the possibility of failed battery devices entering the unloading area for storage, thereby reducing safety risks.

[0206] In some embodiments, the battery device detection method may optionally further include:

[0207] Temperature detection is performed on the battery device in static storage equipment 300 to determine whether the battery device has reached the failure temperature;

[0208] Battery devices that have reached their failure temperature will undergo failure treatment.

[0209] Temperature detection of the battery device in the static storage device 300 can be performed using the first temperature detection element 310 described above.

[0210] The failure treatment of a battery device that has reached its failure temperature can be carried out by the aforementioned transfer device 100. Specifically, the failure battery device can be transferred to the failure treatment equipment 500 via the transfer device 100.

[0211] The above method monitors the temperature of the battery device during the static cooling process. When the temperature of the battery device reaches the failure temperature, the battery device can be disposed of, further reducing the possibility of the failed battery device entering the subsequent material processing process and reducing safety risks.

[0212] In some examples, the battery device detection method may optionally include:

[0213] Temperature detection is performed on the battery devices transferred from the static storage equipment 300 to the unloading area to determine whether the battery devices have reached the failure temperature.

[0214] Battery devices that have reached their failure temperature will undergo failure treatment.

[0215] The above method involves using the second temperature sensor 40 and the third temperature sensor 60 to detect the temperature of the battery device on the transfer device 100. When the temperature reaches the failure standard, the second opening 312 opens, and the battery device enters the disposal cabinet 20.

[0216] The transfer device 100 temporarily manages the failed battery devices in the disposal cabinet 20, and then can directly transport them to the failure treatment equipment 500.

[0217] The above method monitors the temperature of the battery device during transportation. When the temperature of the battery device reaches the failure temperature, the battery device can be disposed of, further reducing the possibility of the failed battery device entering the subsequent material handling process and reducing safety risks.

[0218] Finally, please see the appendix.
