     Lithium-ion power batteries are new high-energy batteries that have been successfully developed in the 20th century. In the 1970s, it became practical. Because of its high energy, high battery voltage, wide operating temperature range and long storage life, it has been widely used in military and civilian small appliances, such as mobile phones, portable computers, video cameras, cameras, etc., and partially replaces traditional batteries. Large-capacity lithium-ion batteries have been tested in electric vehicles and will become one of the main power sources for electric vehicles in the 21st century, and will be used in satellite, aerospace and energy storage.

With the development of microelectronics technology in the twentieth century, the number of miniaturized devices is increasing, and high requirements are placed on power supplies. Lithium-ion power batteries have entered the practical stage of large-scale production. However, the coater is very close in the cell process of the lithium ion power battery.

    The process of the coating machine: the pole piece substrate placed on the unwinding device is pulled out by the roller, and after automatically correcting, enters the floating roller tension system, adjusts the unwinding tension and enters the coating head, and the pole piece slurry is coated. The system's setup program is applied. The coated wet film enters the oven and is dried by hot air. The dried pole piece is tensioned by the tension system, and the winding speed is controlled to synchronize with the coating speed. The pole piece is automatically corrected by the correcting system to keep the substrate in the The center position is neatly wound by the winding device.

Second, the length of the coating section changes, the spacing is unstable:

6. When the back roller and the coating roller are in contact with each other, the gap between the two ends is inconsistent and the pole piece is wrinkled. Regardless of whether the first side or the second side is applied, the gap should be carefully adjusted. First, the gap is appropriately enlarged, and then slowly reduced. At the same time, observe the dial scale of the coating roller just touching the foil strip, and then Reduce the gap by 0.03mm.
7. When the correction system is abnormal, the pole piece will be wrinkled. Check the three correction systems before and after the inspection, whether it is in the automatic state. If the lengths of the foil strips are inconsistent, that is, when the file is bent too much, the pole pieces will be wrinkled. Exceeding the correcting ability, the foil has to be replaced. 8. When the pole piece tension is too large, the pole piece is wrinkled. Check that the tension setting is reasonable. Then check each drive roller. The rotation of the take-up roll is flexible. Handle inflexible rollers in time.
9. When the back roller is in the inconsistent stroke, the pole piece is wrinkled. It is necessary for the mechanic to check. Confirm and adjust. After the back roller and the coating roller are pulled apart, the gap between the two sides is 1mm (see the dial indicator), and the test is started. When the tail is qualified, lock the nut.

10. The surface of the rubber roller on the back roller will undergo periodic elastic deformation during re-use. When a certain degree of deformation remains, wrinkles will occur. At this time, new products must be replaced.
11. The cause of looseness of a certain roller fastening screw causes the parallel state of each roller to be destroyed, and wrinkles may occur at this time. As long as it is found in time to adjust and tighten in time.
