[0014] The utility model has the advantages of the following:

[0015] 1. After the aluminum-cased battery cell enters below the spray gun, the position sensor on the conveyor belt detects its passage. The control equipment then activates the limit cylinder corresponding to the position sensor. The cylinder shaft extends, blocking the battery cell from further transport and positioning it below the CCD camera of the dry ice spray gun. The CCD camera then activates, taking real-time photos and uploading the data to the main unit in the cabinet for logical analysis. After determining the points requiring cleaning, the cleaning trajectory data is transmitted to the PLC in the cabinet. This controls the X and Y modules to align with the electrolyte residue cleaning points on the battery's inlet. Simultaneously, the PLC transmits a signal to control panel one, activating the control reduction motor in the dry ice crushing mechanism. The crushing disc begins to rotate, and the pusher plate pushes the dry ice block closer to the crushing disc for crushing. The electromagnetic output port of the dry ice... When the valve is opened, compressed gas draws out dry ice powder through a siphon effect. The dry ice fragments are then propelled at high speed through the insulated pipe by the high-pressure gas from the dry ice spray gun. When the dry ice particles impact the electrolyte scale surface at the injection port, the extremely low temperature of the dry ice causes the scale to freeze and become brittle, drastically reducing its adhesion to the clean surface. Simultaneously, the dry ice particles shatter upon impact and rapidly sublimate in the cracks of the electrolyte scale layer, expanding in volume and instantly peeling off the scale layer, achieving a residue-free cleaning. At the same time, a CCD camera detects the completion of cleaning at the injection port in real time and transmits the data back. Subsequently, the limit cylinder shaft retracts, and the battery cell is transferred to the next process. The entire cleaning process is fully automated, significantly reducing cleaning time and allowing for real-time monitoring of the cleaning effect, avoiding rework and ensuring cleaning efficiency.

[0016] 2. Before cleaning the battery cells, adjust the following settings as needed: Adjust the initial origin position of the dry ice spray gun and the working position of the Z-axis module via control panel two; set the CCD camera for learning and data analysis; adjust parameters such as ice pressure and ice output via the dry ice crusher control board; after adjustment, turn on the power and press the start button on control panel two to start the equipment. At this time, the aluminum-cased battery cells are conveyed into the equipment via the conveyor belt. When passing the coding scanner on the production line conveyor belt, the coding scanner scans the QR code on the aluminum-cased battery cell and uploads the data to control panel one. The data is then uploaded to the production management system to achieve production traceability.

[0017] 3. PE plastic blocks are placed between the conveyor belts to prevent the bottom of the battery cells from being scratched and to protect the battery cells.

[0018] 4. The spacing between the two ball bearing guides is just enough to allow the aluminum-cased battery cell to pass through, thus guiding and limiting the transmission of the battery cell on the conveyor belt.

[0019] 5, the control panel is used for controlling the start, stop and emergency stop of the cleaning detection mechanism, and the touch screen display is used for adjusting the parameters of the whole cleaning detection mechanism, including real-time display of transmission data of the CCD camera, and stop caused by faults or lack of materials of the equipment, which will be alarmed through three-color alarm lamps to remind the staff.
