1. High precision alloy steel die head make sure the customer can get the best coating effection.
2. Total Machine is controlled by PLC.Precision control coating speed and glue amount.
3. Increase the film function in some glue or substrate is not suitable for direct knife coating that realize 2 kinds of craftwork (knife coating and film coating.) on one machine.
2.4. Coating job related product quality issues:
4) How to judge the bonding performance of the pole piece?
The material can not be removed, and taped to see how much residue, the positive electrode is greater than 1/3, and the negative electrode is greater than 1/2. It can be considered that the bonding is good.
5) How can I handle the correct handling of particles? Plug it with a stopper, if the pellets should be washed, wash the knife
6) What is the relationship between the quality of the knife and the quality of the coated pole piece?
Ensure uniform film density (interpolate the effect of film density on battery performance, capacity)
7) What is the importance of the gap adjustment between the back roller and the coating roller? Too big to carry the material, too small and easy to wear.
8) The importance of mixing.
Prevent slurry stratification and improve slurry consistency
Note on the use of the coater:
2.2 Method of operation:
1) Start up and clean the equipment according to the equipment operation regulations.
2) Under the manual correction, wear the belt according to the requirements of the belt, and restore the automatic correction after wearing. 3) Set the coating temperature, coating speed, speed ratio, and blade gap according to the following table.
4) Start each section of the drying tunnel fan and heating equipment, and the coating can be applied until the temperature of the drying tunnel reaches the process.
5) Pre-adjust the blade gap according to the film density requirements and experience, and fine-tune with the feeler gauge to adjust the blade after adjustment.
6) Set parameters such as coating length, interval, fiber positioning and fiber inspection according to the requirements of the process drawings and the type of ingredients.
7) Install the chute and baffle, and set the “forbidden coating” parameter to the effective state, and turn on the “stirring” kinetic energy.
8) When coating, first press “coating roller”, then press “coating”, and finally cancel “forbidden coating”;
9) After the first side is applied, the parameters should be adjusted according to the process requirements. After the temperature is stable, the second side can be driven by the vehicle.
10) During coating, the film length, empty foil length, and sheet weight of the first side and the second side should be measured at any time and recorded.
11) When the coating is stopped, first press “Forbidden Coating”, then cancel “Coating”, and finally cancel “Coating Roller”. 12) Short-term parking should keep “stirring” on, “painting roller” on and set its line speed to 500m/min.
13) The coated pole piece should be placed on a special iron frame and marked with the mark, and transferred to the next process.
14) Shut down according to the requirements of the equipment operation rules, clean the coating roller, scraper and utensils with alcohol, and do 5S work.
