[0072] The temperature of the dried electrode 3 can be higher than room temperature. If the electrode 3 is wound at a relatively high temperature to form a coil, a physical and / or chemical bond may form between the electrodes 3 when they are cooled.

[0078] For example, the sensor unit 400 can include a second sensor 402 that measures the temperature of a section of the electrode 3 that is heated by the first heating assembly 201 and before it is heated by the second heating assembly 202. Temperature information acquired by the second sensor 402 can be used to generate the fifth signal S5.

[0079] For example, the sensor unit 400 can include a third sensor 403 that measures the temperature of a section of the electrode 3 which is heated by the second heating assembly 202 and before being cooled by the electrode cooling system 70.

[0080] For example, the sensor unit 400 can include a fourth sensor 404 that measures the temperature of a section of the electrode 3 that is cooled by the electrode cooling device 70. The temperature information acquired by the third sensor 403 and the temperature information acquired by the fourth sensor 404 can be used to generate the ninth signal S9.

[0081] The heating, cleaning, and cooling processes of electrode 3 can be investigated. For example, electrode 3 can be preheated. Preheating electrode 3 before it is heated by heating unit 200 can suppress a rapid temperature rise in electrode 3.

[0082] For example, the heating roller unit 100 can heat the electrode 3 while transporting it. The first sensor 401 can measure the temperature of the electrode 3 being heated by the heating roller unit 100.

[0083] For example, the first heating assembly 201 can heat the electrode 3, which is heated by the heating roller unit 100. The electrode 3, heated by the first heating assembly 201, can be transported to the first heated electrode transport arrangement 301.

[0084] The first heated electrode transport assembly 301 can transport the heated electrode 3. For example, electrode 3, which is heated by the first heating assembly 201, can be transported to the second heating assembly 202 via the first heated electrode transport assembly 301.

[0085] The second sensor 402 can measure the temperature of electrode 3 entering the second heating assembly 202. The control unit 80 can extract information about the temperature and temperature distribution of electrode 3 entering the second heating assembly 202 based on the temperature measurement obtained from the second sensor 402.

[0086] For example, the control unit 80 can control the second heating assembly 202 based on the temperature reading acquired by the second sensor 402. For example, the second heating assembly 202 can control at least one of the overall temperature or the temperature distribution of the electrode 3 by being controlled by the control unit 80.

[0087] The electrode 3, which is pulled from the second heating assembly 202, can be transported to the second heated electrode transport arrangement 302.

[0088] The discharge device 500 can remove at least some of the static electricity generated on the electrode 3. The electrode 3, which has passed through the discharge device 500, can be transported to the suction device 600. The suction device 600 can remove at least some of the foreign substances adhering to the electrode 3.

[0089] The electrode 3, which is pulled from the electrode cleaning equipment 50, can be transported to the electrode cooling equipment 70. The electrode cooling equipment 70 can cool the electrode 3 by heat transfer while it is in contact with the electrode 3.

[0090] The third sensor 403 can measure the temperature of the electrode 3 entering the electrode cooling equipment 70. The fourth sensor 404 can measure the temperature of the electrode 3 being withdrawn from the electrode cooling equipment 70.

[0091] The temperature readings obtained by the third sensor 403 and the fourth sensor 404 can form the basis for generating the ninth signal S9. As a result, the electrode cooling equipment 70 can lower the temperature of the electrode 3 to a set temperature. The electrode 3, drawn by the electrode cooling equipment 70, can be wound and formed into a roll.

[0092] Fig. Figure 3 is a flowchart illustrating an electrode drying process according to an embodiment of the present disclosure.

[0093] With reference to Fig. 1 to Fig. 3. The electrode drying process S10 can include a step S100 of heating an electrode. In this step S100, the electrode drying device 1 can heat the electrode 3. As the electrode 3 is heated, its temperature can increase. As the temperature of the electrode 3 increases, the electrode 3 can be dried. This step S100 can be referred to as the electrode heating step.

[0094] The electrode drying process S10 can include a step S200 of cleaning the electrode 3. During the drying process, foreign substances may adhere to the electrode 3. In this step S200, the electrode cleaning equipment 50 can remove at least some of the foreign substances adhering to the electrode 3.

[0095] The electrode drying process S10 can include a step S300 for cooling the electrode. During the drying process, the temperature of electrode 3 can increase. Before electrode 3 is wound into a roll, its temperature must decrease. In this step S300, the electrode cooling device 70 can lower the temperature of electrode 3.

[0096] Fig. Figure 4 is a flowchart showing the electrode heating step.

[0097] With reference to Fig. 1 to Fig. 4. The electrode heating step S100 can include the preheating step S110 of electrode 3. In this step S110, electrode 3 can be preheated.

[0098] For example, in this step S110, the heating roller unit 100 can heat the electrode 3 while transporting it. For example, in this step S110, heat can be transported from the heating roller unit 100 to the electrode 3, so that the temperature of the electrode 3 can increase.

[0099] For example, before step S110, the temperature of electrode 3 might be room temperature. Room temperature could be, for example, 15 to 30 degrees Celsius. For example, during step S110, the temperature of electrode 3 could rise to 40 to 60 degrees Celsius.

[0100] The electrode heating step S100 can include a step S120 for the initial heating of electrode 3. In this step S120, for example, the first heating arrangement 201 can apply heat to electrode 3. For example, the first heating arrangement 201 can send electromagnetic waves, including infrared radiation, to electrode 3. This step S120 can be referred to as the first electrode heating step.

[0101] The electrode heating step S100 can include a step S130 for acquiring information about the temperature of electrode 3. In this step S130, the sensor unit 400 can measure the temperature of electrode 3.

[0102] For example, in this step S130, sensor unit 400 can obtain information about the temperature distribution of electrode 3. The temperature distribution of electrode 3 can be a temperature distribution of electrode 3 in the lateral direction of electrode 3.

[0103] The electrode heating step S100 can include a second heating step S140 of electrode 3. In at least one of these steps S140 or the preceding step S130, the control unit 80 can generate the fifth signal S5 based on the input signals S1 and S2.

[0104] In this step S140, the second heating arrangement 202 can heat the electrode 3 according to the fifth signal S5. The fifth signal S5 can contain information regarding the power distribution of the second heating arrangement 202. This step S140 can be referred to as the second electrode heating step.

[0105] For example, the control unit 80 can control the power distribution of a large number of heating segments 232 (see Fig. 7) adjust the second heating arrangement 202 according to the temperature distribution of the electrode 3 heated in the first electrode heating step S120.

[0106] For example, the output of the heating segment 232 (see Fig. 7), which corresponds to a point with a relatively low temperature under electrodes 3, should be set relatively high.

[0107] For example, the output of the heating segment 232 (see Fig. 7), which corresponds to a point with a relatively high temperature under electrodes 3, can be set relatively low. As a result, the temperature distribution of electrodes 3 can become more uniform.
