This operating procedure is only applicable to ST350-Ⅲ lithium battery pole piece coating machine. ST350-Ⅲ pole piece coating machine operating procedures, in order to ensure safe production and maintain the normal operation of the coating machine, it is necessary to follow the coating machine operating procedures:
- Preparation before starting up
1) Check the electrical switches and wiring for any abnormalities such as falling off or damage.
2) Put on the traction belt under the normal temperature shutdown state according to the requirements of the process sheet.
3) Start the exhaust equipment.
4) Confirm that there is no open flame (such as electric furnace, etc.) in the coating machine room.
5) The control cabinet of the coating machine and the shell of the drying box must be reliably grounded.
- Boot procedure
1) Turn on the main power switch and the power switch on the control cabinet.
2) Set the initial value (usually 180~280) and frequency division number (usually 20~50) on the tension controller.
3) Set the coating working mode and related parameters (coating speed, segment length, gap length, roller speed ratio, etc.), and then connect the compressed air (adjust the pressure regulating valve of the pneumatic control box so that the pneumatic pressure is between 0.2~0.3Mpa between);
4) Start the drying fan and drying temperature controller.
5) Turn on the power of automatic deviation correction and tension controller.
6) The temperature of each section of the equipment has reached the temperature required by the process;
7) Feed the hopper of the coating device and start the coating machine at the same time for coating.Also read:https://www.aimeno.com/lithium-battery/
- Shutdown program
1) Confirm that the coated pole piece has been wound, and then stop the machine.
2) Turn off the power supply of the equipment heater, and stop the drying fan and other fans when the temperature of each section drops below 60 degrees Celsius;
3) Stop the compressed air.
4) Disconnect the power on the correction cabinet and the control cabinet.
- Matters needing attention
1) Operators must receive pre-job training and pass the assessment before they can work, and should strictly abide by the operating procedures.
2) Except for the necessary maintenance personnel, it is strictly forbidden for non-personnel to operate the equipment or change the setting parameters.
3) The roller speed ratio is recommended to be set within the range of 1.3~1.5.
4) The air heater must be activated only after the drying fan has been activated.
5) When adjusting the gap between the coating roller and the backing roller, the slurry on the coating roller should be just wiped off without jamming the backing roller. It is necessary to ensure that the two rollers are parallel and the gap is consistent (there must be a gap).
6) After resetting the parameters, you must press the button to change the parameters.
7) The hopper, scraper, coating roller and back roller must be cleaned with alcohol or acetone immediately after each shift, and the surface must not be scratched or damaged.
8) Pay attention to keep the back roller cylinder and linear slide rail clean and lubricated.
9) The bearing parts of the machine must be lubricated regularly, and the gearbox must be replaced or replenished regularly.
10) Once a problem is found during operation, it must be recorded immediately and notified to the relevant department for timely processing.
11) Do a good job of equipment 58 work at all times, and keep the equipment and surrounding environment clean and tidy.
