Pole roll temperature detection method in lithium battery pole roll baking

The invention discloses a pole roll temperature detection method in lithium battery pole roll baking, and relates to the field of pole roll drying, and the method comprises the following steps: 1) clamping a temperature measurement sliding sheet for inserting a thermocouple probe at the end part of a pole roll when the pole roll is rolled; 2) sliding the temperature measurement sliding sheets to enable the temperature measurement sliding sheets to be symmetrically arranged on the two sides of the pole roll; 3) inserting a thermocouple probe into the temperature measurement slip sheet; 4) heating the pole roll in a baking device, and detecting the temperature of the pole roll through a thermocouple probe. According to the invention, the temperature measurement sliding sheets are pre-buriedin the pole coil during winding, and can slide on the two sides of the pole coil when needing to be symmetrically arranged, so the thermocouple probe is convenient to arrange, the damage to the pole coil is avoided, the therm
