[0036] The second camera module 4 is movably installed on the base frame 1 along the transport direction, used for detecting the injection hole of the battery found by the first camera module 3 to have injection abnormality by shooting again and feeding the detection signal to the control module;
[0037] The driving module is installed on the base frame 1 and is used to control the movement of the second camera module 4.
[0038] The control module is in signal connection with the first camera module 3, the second camera module 4 and the driving module respectively.
[0039] Further, the transport mechanism 2 is a conveying belt.
[0040] Further, the first camera module 3 is a wide-angle camera.
[0041] Further, the second camera module 4 is an infrared camera.
[0042] In the technical solution, the battery cell groups are contained in the battery tray, and after the liquid injection operation, the battery cell groups are transported to the monitoring station by the transport mechanism 2. The transport mechanism 2 can be a conveying belt, which can stably transport the battery tray and the contained battery cell groups to the position below the first camera module 3. The first camera module 3 can be a wide-angle camera, specifically, the wide-angle camera can be a CCD(charge coupled device) camera. The CCD camera can be used to take pictures of the top cover area of all the battery cells on the battery tray and transmit the detection information to the control module. The control module can be a PLC(Programmable Logic Controller), which can automatically perform different operations according to the detection information of the first camera module 3. If the first camera module 3 detects that the battery cells on the battery tray have liquid overflow, the PLC controls the driving module to work, and the driving module controls the second camera module 4 to move along the transport direction, and at the same time, the second camera module 4 takes pictures of the injection hole of the battery cell with liquid injection abnormality. The second camera module 4 can be an infrared camera, which can be used to scan and take pictures of the top cover area of the abnormal battery cell. By using the temperature difference between the electrolyte and the metal top cover, the electrolyte overflow area can be clearly distinguished, and it can be confirmed that the part of the battery cell on the tray is abnormal, so that the abnormal battery can be automatically discharged by the manipulator in the subsequent battery tray disassembly process.
[0043] Further, the display module(not shown in the figure) is in signal connection with the control module, and the display module is used to display the pictures taken by the first camera module 3 and the second camera module 4. The display module can be a display screen, which can display the picture information taken by the first camera module 3 for the staff to observe and identify. If the staff considers that there is liquid injection abnormality, the staff can manually operate the control module to output the working instruction of the second camera module 4 to make the second camera module 4 work to take pictures of the battery cell again.
[0044] In summary, the monitoring device monitors and photographs all the battery cells on the battery tray by setting the first camera module 3. The staff can analyze whether there is an abnormal situation such as electrolyte overflow on the battery cells on the battery tray by observing the photographed image information. If there is an abnormal situation, the control module starts the driving module to drive the second camera module 4 to move to implement further shooting detection on the top cover of the battery cell. By the temperature difference between the electrolyte and the metal top cover, the electrolyte overflow area can be obviously divided, and the abnormal battery cells on the tray can be automatically divided out, which is convenient for discharging when the battery tray is disassembled later, effectively reduces the labor input and the monitoring and investigation time of the monitoring link, enhances the production automation level, and improves the production efficiency.
