Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery testing method, apparatus, system, control device, and storage medium. Background Technology

[0002] During battery production, dimensional checks are required. Current methods involve collecting data from each battery individually on a production line, allowing computer equipment to calculate the battery's dimensions based on this data. However, existing methods can only inspect one battery at a time, resulting in low efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a battery testing method, apparatus, system, control device, and storage medium to improve battery testing efficiency.

[0004] The first aspect of this application provides a battery detection method, including controlling a first clamp to hold a first battery in a first buffer position for a first camera to photograph the first battery, and controlling a second clamp to hold a second battery in a second buffer position for a second camera to photograph the second battery; after the first camera has finished photographing the first battery and the second camera has finished photographing the second battery, controlling the first clamp to hold the first battery in the second buffer position for the second camera to photograph the first battery, and controlling the second clamp to hold the second battery in the first buffer position for the first camera to photograph the second battery; wherein the first camera is used to capture two-dimensional data of the battery, and the second camera is used to capture three-dimensional data of the battery.

[0005] The above implementation scheme allows for simultaneous data acquisition from two batteries (i.e., the first battery and the second battery) in different dimensions, thereby enabling parallel detection of the two batteries. Compared with existing technologies, this can significantly improve battery detection efficiency.

[0006] In a first optional embodiment of the first aspect described above, controlling the second clamp to hold the second battery in the second buffer position for the second camera to take pictures of the second battery includes: controlling the second clamp to hold the second battery in the second buffer position for the second camera to take pictures of the side of the second battery; after the second camera has finished taking pictures of the side of the second battery, controlling the second clamp to rotate the second battery so that the second camera can take pictures of the top and bottom surfaces of the second battery.

[0007] Through the above implementation process, the second camera can capture images of all sides of the second battery, thereby ensuring that the second camera can acquire the three-dimensional data of the second battery.

[0008] In one optional example of the first optional embodiment described above, before controlling the second clamp to clamp the second battery to the first buffer position, the method further includes: controlling the second clamp to rotate the second battery so that the second battery returns to a first initial pose; the first initial pose is the pose of the second battery when it is clamped to the second buffer position.

[0009] Through the above implementation process, the pose of the second battery can be restored after the second camera finishes shooting, so that when the second battery is clamped to the first buffer position, the first camera can face the side of the second battery that needs to be photographed, ensuring that the first camera can obtain the required two-dimensional data of the second battery.

[0010] In a second optional embodiment of the first aspect described above, controlling the first clamp to hold the first battery in the second buffer position for the second camera to take a picture of the first battery includes: controlling the first clamp to hold the first battery in the second buffer position for the second camera to take a picture of the side of the first battery; after the second camera has finished taking a picture of the side of the first battery, controlling the first clamp to rotate the first battery so that the second camera can take pictures of the top and bottom surfaces of the first battery.

[0011] Through the above implementation process, the second camera can capture images of all sides of the first battery, thereby ensuring that the second camera can acquire the three-dimensional data of the first battery.

[0012] In one optional example of the second optional embodiment described above, the method further includes: after the second camera has finished taking pictures of the top and bottom surfaces of the first battery, controlling the first clamp to rotate the first battery so that the first battery returns to a second initial pose; the second initial pose is the pose of the first battery when it is clamped to the second buffer position.

[0013] Through the above implementation process, the pose of the first battery can be restored after the second camera finishes taking pictures, so that the pose of the first battery is consistent with that of the second battery when it enters the subsequent process, which facilitates the processing of subsequent processes.

[0014] In a third optional embodiment of the first aspect above, the method further includes: calculating the length data of the first battery based on the two-dimensional data of the first battery captured by the first camera; and calculating the length data of the second battery based on the two-dimensional data of the second battery captured by the first camera.

[0015] In the above implementation process, the lengths of the first and second batteries can be quickly determined based on the two-dimensional data of the first and second batteries, thus achieving the effect of size detection.

[0016] In a fourth optional embodiment of the first aspect above, the method further includes: calculating the flatness data and height data of the first battery based on the three-dimensional data of the first battery captured by the second camera; and calculating the flatness data and height data of the second battery based on the three-dimensional data of the second battery captured by the second camera.

[0017] In the above implementation process, the flatness data and height data of the first battery and the second battery can be quickly determined based on the three-dimensional data of the first battery and the second battery, thus achieving the effect of size detection.

[0018] In a fifth optional embodiment of the first aspect described above, the first clamp integrates a first probe, and the second clamp integrates a second probe; the method further includes: when the first clamp holds the first battery, controlling the first probe to pop out to contact the positive terminal, negative terminal, and end plate of the first battery, and outputting a voltage to at least one of the positive terminal, negative terminal, and end plate of the first battery to measure the electrical performance of the first battery; when the second clamp holds the second battery, controlling the second probe to pop out to contact the positive terminal, negative terminal, and end plate of the second battery, and outputting a voltage to at least one of the positive terminal, negative terminal, and end plate of the second battery to measure the electrical performance of the second battery.

[0019] In the above implementation process, by integrating the first probe in the first fixture and the second probe in the second fixture, the electrical performance of the first and second batteries can be tested simultaneously during the dimensional inspection process, which shortens the time required for the entire battery production or inspection process and improves the inspection efficiency.

[0020] A second aspect of this application also provides a battery detection device, comprising: a control module, configured to control a first clamp to hold a first battery in a first buffer position for a first camera to photograph the first battery, and to control a second clamp to hold a second battery in a second buffer position for a second camera to photograph the second battery; the control module is further configured to, after the first camera has finished photographing the first battery and the second camera has finished photographing the second battery, control the first clamp to hold the first battery in the second buffer position for the second camera to photograph the first battery, and control the second clamp to hold the second battery in the first buffer position for the first camera to photograph the second battery; wherein the first camera is used to capture two-dimensional data of the battery, and the second camera is used to capture three-dimensional data of the battery.

[0021] In an optional embodiment of the second aspect described above, the first clamp integrates a first probe, and the second clamp integrates a second probe; the control module is further configured to, when the first clamp holds the first battery, control the first probe to pop out to contact the positive terminal, negative terminal, and end plate of the first battery, and output a voltage to at least one of the positive terminal, negative terminal, and end plate of the first battery to measure the electrical performance of the first battery; and when the second clamp holds the second battery, control the second probe to pop out to contact the positive terminal, negative terminal, and end plate of the second battery, and output a voltage to at least one of the positive terminal, negative terminal, and end plate of the second battery to measure the electrical performance of the second battery.

[0022] A third aspect of this application also provides a battery testing system, including: a control device, a first camera, a second camera, a first fixture, and a second fixture; the control device is communicatively connected to the first camera, the second camera, the first fixture, and the second fixture, respectively; wherein: the control device is used to execute any of the above-described battery testing methods.

[0023] A fourth aspect of this application also provides a control device, including: a processor, a memory, and a communication module; the communication module is used to communicate with an external first camera, a second camera, a first fixture, and a second fixture; the processor is used to execute a program stored in the memory to implement any of the above-described battery detection methods.

[0024] A fifth aspect of the embodiments of this application also provides a computer-readable storage medium storing one or more programs that can be executed by one or more processors to implement any of the above-described battery detection methods. Attached Figure Description

[0034] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0036] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will understand that the embodiments described herein can be combined with other embodiments.

[0038] Currently, batteries are widely used in electrical equipment such as electric bicycles, electric motorcycles, drones, and electric vehicles, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0039] The inventors have noted that currently, in the battery manufacturing process, battery size inspection is performed by collecting data from each battery individually on an inspection line, and then using computer equipment to calculate the battery size based on the collected data. This inspection method can only inspect one battery at a time, resulting in low inspection efficiency.

[0040] Therefore, in this application embodiment, the inventors propose a new battery detection method, which detects two batteries at once by alternately capturing two-dimensional data and three-dimensional data of two batteries, thereby improving detection efficiency.

[0041] Please see below. Figure 1 As shown, Figure 1 The basic flow of the battery detection method provided in the embodiments of this application is shown, including:

[0042] S101: Control the first clamp 15 to clamp the first battery A to the first buffer position 13 so that the first camera 11 can take pictures of the first battery A, and control the second clamp 16 to clamp the second battery B to the second buffer position 14 so that the second camera 12 can take pictures of the second battery B.

[0043] In this embodiment, a dedicated battery inspection system can be set up to detect the size of the battery. The structure of the battery inspection system can be found in [reference needed]. Figure 2 As shown, it includes a first camera 11, a second camera 12, a first clamp 15, and a second clamp 16 (as shown). Figure 6(As shown in the diagram). The first camera 11 can be a 2D camera, used to capture two-dimensional data of the battery, and can be positioned at the top of the shooting area. The second camera 12 can be a 3D camera, used to capture three-dimensional data of the battery, and can be positioned on either side of the shooting area. The relative positions of the first camera 11 and the second camera 12 can be found in [reference needed]. Figure 2 As shown. It can be understood that the first camera 11 and the second camera 12 can also be other cameras in the field, such as line scan cameras, area scan cameras, infrared sensors, etc., as needed.

[0044] In this embodiment of the application, the shooting area refers to the area in the pre-set battery detection system that can be captured by the first camera 11 and the second camera 12, for example... Figure 2 The area indicated by the dashed box 17.

[0045] In this embodiment of the application, the number of the first camera 11 and the second camera 12 can be one or more, and this embodiment of the application does not limit this.

[0046] In this embodiment, the first buffer bit 13 and the second buffer bit 14 can be preset according to the positions of the first camera 11 and the second camera 12, so that the first camera 11 and the second camera 12 can clearly capture the required data. It can be understood that the first buffer bit 13 and the second buffer bit 14 are located within the shooting area.

[0047] For example, such as Figure 2 As shown, the first buffer bit 13 is located near the first camera 11, and the second buffer bit 14 is lower than the first buffer bit 13 and is located between the second cameras 12.

[0048] In the embodiments of this application, the first clamp 15 and the second clamp 16 can be clamps such as robotic arms that can achieve controlled clamping functions, or other devices or equipment with clamping functions commonly found in the art. This application does not impose specific limitations here.

[0049] In this embodiment, the battery detection system may further include a control device, which executes the battery detection method provided in this embodiment. Optionally, the control device may be an electronic device such as a server or computer, or an electronic component with control functions such as a PLC (Programmable Logic Controller), CPU (Central Processing Unit / Processor), or microcontroller.

[0050] In this embodiment of the application, the battery detection system may further include a conveyor belt to transport the first battery A and the second battery B to be detected, thereby transporting the first battery A and the second battery B to a set clamping position for clamping by the first clamp 15 and the second clamp 16.

[0051] In the embodiments of this application, the first battery A and the second battery B can be a single battery cell, a battery module, or a battery pack, and there are no restrictions on this in the embodiments of this application.

[0052] As can be understood, a battery cell is the smallest unit that makes up a battery. A battery cell may include a battery cell and may be housed in a casing, taking the form of a cylinder, flattened body, cuboid, or other shapes. A battery cell may be a secondary battery or a primary battery, and may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these.

[0053] A battery module is a battery structure formed by connecting multiple battery cells in series, parallel, or a hybrid connection. A hybrid connection refers to multiple battery cells being connected in both series and parallel configurations. In addition to battery cells, a battery module may also include a busbar component to enable electrical connections between the multiple battery cells.

[0054] A battery pack can be a battery structure formed by connecting multiple battery modules in series, parallel, or a combination thereof. Alternatively, a battery pack can also be a battery structure formed by connecting multiple individual battery cells in series, parallel, or a combination thereof. Besides battery modules or individual battery cells, a battery pack can also include other structures, such as a Battery Management System (BMS), but this is not a limitation.

[0055] S102: After the first camera 11 finishes taking pictures of the first battery A and the second camera 12 finishes taking pictures of the second battery B, control the first clamp 15 to clamp the first battery A to the second buffer position 14 so that the second camera 12 can take pictures of the first battery A, and control the second clamp 16 to clamp the second battery B to the first buffer position 13 so that the first camera 11 can take pictures of the second battery B.

[0056] In this manner, while the first camera 11 is capturing images of the first battery A to obtain its two-dimensional data, the second camera 12 is simultaneously capturing images of the second battery B to obtain its three-dimensional data. Similarly, while the first camera 11 is capturing images of the second battery B to obtain its two-dimensional data, the second camera 12 is simultaneously capturing images of the first battery A to obtain its three-dimensional data. This achieves parallel detection of the two batteries, potentially doubling the battery detection efficiency compared to existing technologies.

[0057] In one optional embodiment of this application, after controlling the second clamp 16 to clamp the second battery B to the second buffer position 14, as follows Figure 2 As shown, the second camera 12 can first take pictures of the side of the second battery B. After the second camera 12 has finished taking pictures of the side of the second battery B, the second clamp 16 can be controlled to rotate the second battery B so that the second camera 12 can take pictures of the top and bottom surfaces of the second battery B. The shooting effect at this time is as follows. Figure 3 As shown. In this way, the second camera 12 can capture images of all sides of the second battery B, thereby ensuring that the second camera 12 can acquire the three-dimensional data of the second battery B.

[0058] In the above optional embodiment, before controlling the second clamp 16 to clamp the second battery B to the first buffer position 13, the second clamp 16 can also be controlled to rotate the second battery B to restore the second battery B to the first initial pose. The first initial pose is the pose of the second battery B when it is clamped to the second buffer position 14. Thus, when the second battery B is clamped to the first buffer position 13, the first camera 11 can be aligned with the side of the second battery B that needs to be photographed, ensuring that the first camera 11 can acquire the required two-dimensional data of the second battery B.

[0059] For example, the second clamp 16 first clamps the second battery B to the second buffer position 14 for the second camera 12 to take pictures. At this time, the position of the second battery B is as follows: Figure 2 As shown. After the second camera 12 finishes taking pictures of the side of the second battery B, the second clamp 16 is controlled to rotate the second battery B by 90 degrees, so that the second camera 12 can take pictures of the top and bottom surfaces of the second battery B. At this time, the position of the second battery B is as shown. Figure 3 As shown. After the second camera 12 has taken pictures of the top and bottom surfaces of the second battery B, the second clamp 16 is controlled to rotate the second battery B 90 degrees in the opposite direction. At this time, the pose of the second battery B is restored to the position shown. Figure 2 As shown, when the second battery B is clamped to the first buffer position 13, the top surface of the second battery B can be kept facing upwards, ensuring that the first camera 11 takes a picture of the top surface of the second battery B.

[0060] Similarly, in an optional embodiment of this application, after the first camera 11 has finished taking pictures of the first battery A and the second camera 12 has finished taking pictures of the second battery B, the first clamp 15 can be controlled to clamp the first battery A to the second buffer position 14 so that the second camera 12 can take pictures of the side of the first battery A, for example. Figure 4 As shown. After the second camera 12 finishes taking pictures of the side of the first battery A, the first clamp 15 is controlled to rotate the first battery A, so that the second camera 12 can take pictures of the top and bottom surfaces of the first battery A, for example. Figure 5As shown. In this way, the second camera 12 can capture images of all sides of the first battery A, thereby ensuring that the second camera 12 can acquire the three-dimensional data of the first battery A.

[0061] In the above optional embodiment, after the second camera 12 has finished photographing the top and bottom surfaces of the first battery A, the first clamp 15 can be controlled to rotate the first battery A, so that the first battery A returns to its second initial pose. The second initial pose is the pose of the first battery A when it is clamped to the second buffer position 14. This allows for the restoration of the pose of the first battery A. Since there may be other subsequent processes besides battery size inspection in the battery production or testing process, restoring the position of the first battery A to the second initial pose ensures that the poses of the first battery A and the second battery B are consistent, facilitating subsequent processing.

[0062] It is understood that in the above optional embodiments, when the first battery A or the second battery B is located in the second buffer position 14, the second camera 12 first takes pictures of both sides, and then takes pictures of the top and bottom surfaces after the side pictures are taken. After the pictures are taken, the pose is restored. However, in addition to the above embodiments, in the embodiments of this application, when the first battery A or the second battery B is located in the second buffer position 14, the first battery A or the second battery B can also be rotated first so that the second camera 12 takes pictures of the top and bottom surfaces first. After the pictures are taken, the pose is restored, and the second camera 12 takes pictures of both sides.

[0063] In an optional embodiment of this application, a first initial cache position and a second initial cache position can be set, so that the first clamp 15 and the second clamp 16 respectively clamp the first battery A and the second battery B to the first initial cache position and the second initial cache position at the same height, and then clamp the first battery A from the first initial cache position to the first cache position 13, and clamp the second battery B from the second initial cache position to the second cache position 14.

[0064] In one example scheme, the first initial cache position may coincide with the position of the first cache bit 13, in which case the second initial cache bit is another position at the same height as the first cache bit 13. In another example scheme, the second initial cache position may coincide with the position of the second cache bit 14, in which case the first initial cache position is another position at the same height as the second cache bit 14.

[0065] Of course, in this embodiment, the first initial cache position and the second initial cache position may not be set. Instead, the first clamp 15 is directly controlled to clamp the first battery A to the first cache position 13, and the second clamp 16 is controlled to clamp the second battery B to the second cache position 14. This embodiment does not limit this.

[0066] In this embodiment of the application, the length data of the first battery A can be calculated based on the two-dimensional data of the first battery A captured by the first camera 11, and the length data of the second battery B can be calculated based on the two-dimensional data of the second battery B captured by the first camera 11.

[0067] For example, each first camera 11 can be calibrated in the same coordinate system, and then the two-dimensional data (which can be 2D images) captured by each first camera 11 can be processed to obtain the four edge information of the battery. Then, the edge information on the same side is merged to fit a straight line. Finally, the distance from the opposite edge to the straight line is calculated to obtain the length of each side of the battery.

[0068] It is understood that the above is merely an example of a method for calculating the length of a battery based on two-dimensional battery data in this application embodiment, and is not intended to limit the embodiments of this application.

[0069] It can also be understood that the length data mentioned in the embodiments of this application may include the overall length and width of the battery, the distance between the bottom of the battery and the bottom of the end plate, the fixed length of the end plate hole, etc. The above examples illustrate the methods for calculating the overall length and width of the battery. For the distance between the bottom of the battery and the bottom of the end plate, the fixed length of the end plate hole, etc., they can also be calculated with reference to existing algorithms, or they can be directly obtained by scanning by the first camera 11. This embodiment of the application does not limit this.

[0070] In this embodiment, the flatness data and height data of the first battery A can be calculated based on the three-dimensional data of the first battery A captured by the second camera 12, and the flatness data and height data of the second battery B can be calculated based on the three-dimensional data of the second battery B captured by the second camera 12. The flatness data reflects the flatness of each surface of the battery, and the height data reflects the height of the battery.

[0071] For example, in this embodiment of the application, the flatness data may include the most convex point, the most concave point, the average convexity value of each point in the plane, the maximum distance, the minimum distance, and the average distance (i.e., the average distance between corresponding points on two surfaces) of each surface. The flatness data of the battery can be calculated in the following ways:

[0072] Each of the second cameras 12 can be calibrated in the same coordinate system. Then, the three-dimensional data (which can be 3D images) can be processed to obtain the flatness of the L / R plane. The three-dimensional data can then be processed to obtain the most convex point, the most concave point, and the average value of the L / R plane. Afterward, the maximum distance, the minimum distance, and the average distance between the two planes can be calculated based on their most convex point, the most concave point, and the average value.

[0073] For example, in this embodiment, the battery height data can be calculated as follows: the average height of the electrode planes in the battery can be calculated and represented as a point. Then, the point on the bottom surface is fitted to a reference plane, and finally, the distance from the point to the reference plane is calculated. This distance is the battery height. It is understood that the calculation of the electrode planes and the average height of the electrode planes in the battery can refer to the prior art, and will not be elaborated upon in this embodiment.

[0074] It is understood that the above are merely examples of how to calculate the flatness data of a battery based on its three-dimensional data and how to calculate the height data of a battery based on its three-dimensional data, and are not intended to limit the scope of the embodiments of this application.

[0075] In this embodiment of the application, by calculating the length data, flatness data, and height data of the battery, full-size detection of the battery can be achieved, thereby more comprehensively detecting the size of the battery.

[0076] In this embodiment, a first probe can be integrated into the first clamp 15, and a second probe can be integrated into the second clamp 16. During the testing of the first battery A and the second battery B, when the first clamp 15 holds the first battery A, the first probe can be controlled to pop out to contact the positive terminal, negative terminal, and end plate of the first battery A, and output voltage to at least one of the positive terminal, negative terminal, and end plate of the first battery A to measure the electrical performance of the first battery A. Correspondingly, when the second clamp 16 holds the second battery B, the second probe can be controlled to pop out to contact the positive terminal, negative terminal, and end plate of the second battery B, and output voltage to at least one of the positive terminal, negative terminal, and end plate of the second battery B to measure the electrical performance of the second battery B. In this way, under the action of the first probe and the second probe, the electrical performance testing of the first battery A and the second battery B can be performed simultaneously during the dimensional inspection process. Performing the dimensional inspection and electrical performance testing of the batteries simultaneously shortens the time consumed in the entire battery production or testing process and improves the testing efficiency.

[0077] It is understood that the electrical performance testing items performed in the embodiments of this application may include, but are not limited to: module total voltage, IMP (Internal Impedance, module AC internal resistance) test, total positive and shell insulation resistance test, and total positive and shell withstand voltage test.

[0078] It is also understood that the battery testing system in this application embodiment may integrate testing devices such as digital multimeters, internal resistance meters, and insulation withstand voltage meters. These testing devices can be connected to probes through switching devices such as relays. The control equipment or other host computer software with data processing capabilities can control the relays to switch circuits, so that the probes are connected to different circuits to measure different electrical performance test items, but this is not a limitation.

[0079] To facilitate understanding of the solutions in the embodiments of this application, the following will be used as examples. Figure 6 The structure shown is used as an example to illustrate the solution of this application embodiment:

[0080] Assuming the object being detected is a battery module, the first camera 11 is a 2D camera, and the second camera 12 is a 3D camera:

[0081] During battery module testing, battery modules A1 and B1 can be carried on a pallet along a conveyor belt into the battery testing system and reach the designated position.

[0082] Subsequently, the first clamp 15 can clamp the battery module A1 and lift it to the first initial buffer position, and the second clamp 16 can clamp the battery module B1 and lift it to the second initial buffer position.

[0083] This example assumes that the second initial cache location is the same as the location of the second cache bit 14. Afterwards:

[0084] The first clamp 15 holds the battery module A1 and lifts it to the first buffer position 13, while the battery module B1 remains at the second initial buffer position.

[0085] Subsequently, the top 2D camera photographs battery module A1, detecting data such as module A's length, width, distance between its bottom and the bottom of the end plate, and the fixed length of the end plate holes. The two 3D cameras on either side photograph the two sides of battery module B1. After the photographing is completed, the second clamp 16 holds battery module B1 and rotates it 90°, rotating the top and bottom surfaces of battery module B1 to the left and right sides, thereby scanning and obtaining data such as the height, bottom flatness, and end plate corner flatness of battery module B1.

[0086] Subsequently, the first clamp 15 clamps the battery module A1 and moves it downward, while the second clamp 16 clamps the battery module B1, rotates it 90° in the opposite direction, and moves it upward until the battery module A1 moves to the second buffer position 14 and the battery module B1 moves to the first buffer position 13.

[0087] Subsequently, the top 2D camera photographs battery module B1, detecting data such as module B's length, width, distance between its bottom and the bottom of the end plate, and the fixed length of the end plate holes. The two 3D cameras on either side photograph the two sides of battery module A1. After the photographing is completed, the first clamp 15 holds battery module A1 and rotates it 90°, rotating the top and bottom surfaces of battery module A1 to the left and right sides, thereby scanning and obtaining data such as the height, bottom flatness, and end plate corner flatness of battery module A1.

[0088] Subsequently, the first clamp 15 clamps battery module A1, rotates it 90° in the opposite direction, and moves it to the first initial buffer position, placing battery module A1 on the tray; the second clamp 16 clamps battery module B1 and moves it down to the second initial buffer position, placing battery module B1 on the tray, and battery modules A1 and B1 are released.

[0089] During the above process, the first probe of the first clamp 15 pops out to contact the positive terminal, negative terminal and end plate of the battery module A1, and outputs voltage to the positive terminal, negative terminal and end plate of the battery module A1 to measure the electrical performance of the battery module A1; the second probe of the second clamp 16 pops out to contact the positive terminal, negative terminal and end plate of the battery module B1, and outputs voltage to the positive terminal, negative terminal and end plate of the battery module B1 to measure the electrical performance of the battery module B1.

[0090] In this example, by performing the electrical performance testing and dimensional testing of the battery module in parallel, the testing and production efficiency of the battery module is improved. Furthermore, performing the testing of two battery modules simultaneously during dimensional testing further enhances testing and production efficiency.
