[0093] It should be noted that the triggering methods of the image acquisition device 121 and the height acquisition device 122 are not limited to those described above. Furthermore, the order of the image detection station and the height acquisition station in this embodiment can be set according to actual conditions. For example, the image of the battery cell 30 can be acquired first at the image detection station, and then the height of the battery cell 30 can be acquired at the height detection station; or, the height of the battery cell 30 can be acquired first at the height detection station, and then the image of the battery cell 30 can be acquired at the image detection station.

[0094] In the above embodiments, the image acquisition device acquires the electrode image of the battery cell; the height acquisition device acquires the battery cell height; the controller determines the electrode position based on the electrode image, and controls the assembly assembly to assemble the test cover plate and the tray based on the electrode position and the battery cell height.

[0097] Subsequently, the controller 14 controls the assembly assembly 13 based on the horizontal position and height of the probe assembly, causing the assembly assembly 13 to adjust the actual position of the probe assembly on the test cover plate 22. After adjustment, the controller 14 controls the assembly assembly 13 to assemble the test cover plate 22 with the tray 21, so that the detection end of the probe assembly on the test cover plate 22 is connected to the electrode of the battery cell 30. In this way, the battery cell testing equipment can obtain relevant data of the battery cell 30 through electrical connection with the test fixture 20, thereby realizing battery cell testing.

[0098] In the above embodiments, the controller controls the assembly assembly to adjust the probe position of the test cover plate according to the electrode position and the cell height, and then assembles the test cover plate with the tray. Adjusting the probe position of the test cover plate in this embodiment allows the detection end of the probe assembly to more closely correspond to the electrode position of the cell, improving the assembly accuracy of the test fixture and the cell.

[0099] According to some embodiments of this application, the controller 14 is used to control the assembly assembly 13 to adjust the position of the probe assembly of the test cover 22 in the horizontal direction according to the electrode position, and to control the assembly assembly 13 to adjust the probe height of the test cover 22 according to the cell height.

[0100] In this embodiment, the controller 14 determines the position of the probe assembly in the horizontal direction based on the electrode position, and then controls the assembly assembly 13 based on the position of the probe assembly in the horizontal direction, so that the assembly assembly 13 adjusts the actual position of the probe assembly.

[0101] The controller 14 determines the height of the probe assembly based on the height of the battery cell, and then controls the assembly assembly 13 based on the height of the probe assembly, so that the assembly assembly 13 adjusts the actual height of the probe assembly.

[0102] It should be noted that the test cover 22 includes structures related to the position and height of the probe assembly in the horizontal direction. The assembly assembly 13 can adjust the actual position of the probe assembly by adjusting these structures.

[0103] In the above embodiments, the controller controls the assembly assembly to adjust the horizontal position of the probe assembly of the test cover plate according to the electrode position, and controls the assembly assembly to adjust the probe height of the test cover plate according to the cell height. By adjusting the horizontal position and probe height of the probe assembly through the assembly assembly, the detection end of the probe assembly can more closely correspond to the electrode position of the cell, thereby improving the assembly reliability of the test fixture and the cell.

[0104] According to some embodiments of this application, the controller 14 is also used to control the assembly assembly 13 to move the test cover 22 from a preset buffer station to a preset adjustment station, and adjust the probe position of the test cover 22 at the adjustment station.

[0105] In this embodiment, the assembly equipment 10 may further include a buffer station and an adjustment station, as shown in the following example. Figure 3 The cache station can store multiple test covers 22.

[0106] The controller 14 controls the assembly assembly 13 to move the test cover 22 from the buffer station to the adjustment station, and adjusts the probe position at the adjustment station. Then, the controller 14 assembles the adjusted test cover 22 with the tray 21 located at the assembly station to obtain the structure to be tested.

[0107] In the above embodiments, the controller controls the assembly assembly to move the test cover plate from a preset buffer station to a preset adjustment station, and adjusts the probe position of the test cover plate at the adjustment station. This embodiment stores multiple test cover plates at the buffer station, which improves assembly continuity, thereby increasing assembly efficiency and ultimately improving testing efficiency.

[0109] In this embodiment of the application, the assembly equipment 10 may further include a reliability detection component 15, and the controller 14 is connected to the reliability detection component 15.

[0110] After assembling the test cover 22 with the tray 21, the controller 14 controls the reliability detection component 15 to detect the battery cell 30 and obtain detection data. Then, the controller 14 obtains the detection data from the reliability detection component 15 and determines the reliability of the assembly between the test cover 22 and the tray 21 based on the detection data.

[0111] For example, the controller 14 controls the reliability detection component 15 to apply voltage to the battery cell 30 and collect the battery cell current; the controller 14 obtains the battery cell current from the reliability detection component 15. If the battery cell current is within the preset current range, the detection result is determined to be that the assembly between the test cover 22 and the tray 21 is reliable; if the battery cell current is not within the preset current range, the detection result is determined to be that the assembly between the test cover 22 and the tray 21 is unreliable.

[0112] In some embodiments, if the detection result indicates that the assembly between the test cover 22 and the tray 21 is unreliable, the controller 14 outputs an alarm message indicating an assembly abnormality. For example, the assembly equipment 10 is also provided with at least one of a display and an audio-visual device. The controller 14 can control the display to show the alarm message and / or control the audio-visual device to emit an audible and visual alarm. It should be noted that the output method of the alarm message is not limited to the above description and can be set according to the actual situation.

[0147] According to some embodiments of this application, refer to Figure 13 An assembly method is provided. Taking the application of this method to the assembly equipment in the above embodiments as an example, it may include the following steps:

[0148] Step 401: Obtain the cell information of the battery cell, wherein the battery cell is placed on the tray of the test fixture.

[0149] The assembly equipment includes an information detection component and a controller. The testing fixture includes a tray on which the battery cells are placed. The tray carrying the battery cells is located at the testing station of the assembly equipment. The information detection component performs information detection on the battery cells to obtain their information. The controller obtains the battery cell information from the information detection component.

[0150] Step 402: Control the position adjustment component of the assembly equipment to move the tray according to the cell information.

[0151] The assembly equipment also includes a position adjustment component, on which a tray carrying the battery cells is placed. After acquiring the battery cell information, the controller controls the position adjustment component to move the tray to the assembly station.

[0152] Step 403: When the pallet is located at the preset assembly station, the assembly components of the control assembly equipment assemble the test cover of the test fixture with the pallet to obtain the structure to be tested.

[0153] The assembly equipment also includes assembly components, and the testing fixture includes a test cover. When the pallet is in the assembly station, the controller controls the assembly components to assemble the test cover with the pallet, thus obtaining the structure to be tested.

The steps of obtaining the cell information described above may include: obtaining an electrode image of the cell from an image acquisition device of the assembly equipment and determining the electrode position based on the electrode image; and obtaining the cell height from a height acquisition device of the assembly equipment.

[0156] Information detection devices for assembly equipment can include image acquisition devices and height acquisition devices. Image acquisition devices can acquire images of the battery cells to obtain electrode images, while height acquisition devices can acquire the height of the battery cells to obtain the battery cell height.

[0157] The controller of the assembly equipment acquires electrode images from the image acquisition device, identifies the electrode images, and obtains the electrode positions. In practical applications, the process of identifying electrode images may include: inputting the electrode images into a pre-trained image recognition model to obtain the electrode positions output by the image recognition model. The image recognition model may include, but is not limited to, deep learning models and neural network models. It should be noted that electrode image identification is not limited to the methods described above, and other methods may also be used.

[0158] The controller determines the electrode position based on the electrode image and obtains the cell height from the height acquisition device to obtain cell information.

[0159] In the above embodiments, electrode images of the battery cell are acquired from the image acquisition device of the assembly equipment, and the electrode positions are determined based on the electrode images; the battery cell height is acquired from the height acquisition device of the assembly equipment. The electrode positions and battery cell heights obtained in this application embodiment provide a basis for subsequent adjustment of the probe positions, which can improve the accuracy and reliability of assembly, and thus improve the accuracy of battery cell testing.

[0160] According to some embodiments of this application, the step of assembling the test cover plate and the tray by the assembly component of the above-described control assembly equipment may include: adjusting the probe position of the test cover plate according to the electrode position and the cell height, and assembling the test cover plate and the tray.

[0161] The controller controls the assembly assembly based on the electrode position, causing the assembly assembly to adjust the horizontal position of the probe assembly; the controller also controls the assembly assembly based on the cell height, causing the assembly assembly to adjust the height of the probe assembly. After the probe position is adjusted, the controller controls the assembly assembly to assemble the test cover plate with the tray.

[0162] The aforementioned assembly component adjusts the probe position by adjusting the adjustment component of the test cover plate. In some embodiments, the adjustment component of the test cover plate includes a guide rail structure and a lifting plate. The assembly component allows the probe component of the test cover plate to slide on the guide rail structure, thereby adjusting the horizontal position of the probe component; the assembly component also allows the lifting plate to rise or fall, thereby adjusting the height of the probe component. In other embodiments, the adjustment component of the test cover plate includes a first lead screw adjustment component, a second lead screw adjustment component, and a lifting plate. The assembly component adjusts the first and second lead screw adjustment components to adjust the horizontal position of the probe component; the assembly component also allows the lifting plate to rise or fall, thereby adjusting the height of the probe component.

[0164] The aforementioned assembly components may include, but are not limited to, robotic arms.

[0165] In the above embodiments, the probe position of the test cover is adjusted according to the electrode position and cell height, and the test cover is then assembled with the tray. This embodiment of the application improves the accuracy and reliability of the assembly by adjusting the probe position based on the electrode position and cell height, thereby improving the accuracy of cell testing.

[0166] According to some embodiments of this application, it may also include: controlling the reliability testing component of the assembly equipment to test the battery cell and obtain the test result, the test result being used to characterize the assembly reliability of the test cover and tray.

[0167] The assembly equipment also includes a reliability testing component. After the test cover is assembled with the tray, the controller controls the reliability testing component to test the battery cell and obtain test data. Then, the controller retrieves the test data from the reliability testing component and determines the reliability of the assembly between the test cover and the tray based on the test data.

[0168] Alternatively, the controller controls the reliability testing component to test the battery cell and obtain test data. The reliability testing component then determines the test result based on the test data to determine whether the assembly between the test cover and the tray is reliable.

[0169] In some embodiments, if the detection result indicates that the assembly between the test cover and the tray is unreliable, the controller outputs an alarm message indicating an assembly abnormality. For example, the assembly equipment may also be equipped with at least one of a display and an audible and visual device, and the controller may control the display to show the alarm message and / or control the audible and visual device to issue an audible and visual alarm. It should be noted that the output method of the alarm message is not limited to the above description and can be set according to the actual situation.
