Abstract
An electrode sheet manufacturing device includes a pair of rolls that press an electrode active material layer formed on an electrode sheet, a press pressure adjusting mechanism that adjusts a press pressure of the pair of rolls, a temperature sensor that detects a surface temperature of at least one of the pair of rolls, and a controller. The controller is configured to adjust the press pressure, based on the surface temperature of the at least one of the pair of rolls detected by the temperature sensor.
Claims6
An electrode sheet manufacturing device comprising:
- a pair of rolls including a lower press roll and an upper press roll, wherein the pair of rolls press an electrode active material layer formed on an electrode sheet;
- a press pressure adjusting mechanism that adjusts a press pressure of the pair of rolls, wherein the press pressure adjusting mechanism includes a pair of bend cylinders that bend the rolls, the pair of bend cylinders arranged on opposing sides of the rolls between a respective shaft portion of the upper press roll and a respective shaft portion of the lower press roll;
- a temperature sensor that detects a surface temperature of at least one of the pair of rolls;
- and
- a controller,
- wherein the controller stores correlation data between the temperature detected by the temperature sensor and a thickness of the electrode sheet in advance, and
- wherein the controller is configured to control the press pressure by adjusting a bend pressure with which the pair of bend cylinders bend the rolls, based on the surface temperature of the at least one of the pair of rolls detected by the temperature sensor and the correlation data.
