[0020] Furthermore, the present invention is not limited to the above-described embodiments, and various modifications and variations are possible from the above description by a person having ordinary skill in the art to which the present invention pertains. Therefore, the spirit of the present invention should not be limited to the above-described embodiments, and it can be said that not only the scope of the claims below, but also any equivalent or modified version of the claims falls within the spirit of the present invention.

[0021] [First embodiment] FIG. 1 shows a heat source device 1 according to a first embodiment of the present invention. Referring to FIG. 1, a heat source device 1 according to a first embodiment of the present invention may include a lamp 10, a plate 20, a distance sensor 31, a driving unit 40, and a control unit 50.

[0022] The lamp 10 can emit electromagnetic waves to dry the electrode a. The lamp 10 can emit electromagnetic waves to generate radiant heat on the electrode a, thereby drying the coating material on the electrode. The lamp 10 can be a medium wave infrared (MIR) lamp. The lamp 10 can emit medium infrared rays to generate radiant heat on the electrode a. The wavelength range of the medium infrared rays emitted from the lamp 10 can be, for example, 2 μm to 6 μm. A plurality of lamps 10 can be provided. The plurality of lamps 10 can be arranged side by side at equal intervals. The electrode a can be provided on the optical path of the electromagnetic waves emitted from the lamp 10.

[0023] The plate 20 allows at least a portion of the electromagnetic waves from the lamp 10 toward the electrode a to pass through. The plate 20 can be provided to adjust the shape and luminous intensity of the electromagnetic waves from the lamp 10 toward the electrode a. The plate 20 can be disposed between the lamp 10 and the electrode a. Depending on the configuration of the plate 20, it is possible to control the electromagnetic waves from the lamp 10 to reach a specific position on the electrode a that requires thermal drying. The plate 20 can be disposed parallel to the arrangement direction of the multiple lamps 10. The plate 20 can have plate holes that allow at least a portion of the electromagnetic waves from the lamps 10 to pass through. The shape of the plate 20 will be described in detail with reference to FIG. 2 below.

[0024] The distance sensor 31 may be provided to sense the distance between the lamp 10 and the plate 20. The distance sensor 31 may be, for example, a fiber sensor. The fiber sensor is flexible and bendable, allowing it to be stably installed even in a narrow space. The distance sensor 31 may be disposed on the plate 20 to sense the distance between the plate 20 and the lamp 10. The distance sensor 31 may be fastened and fixed to the plate 20, for example. The distance sensor 31 may be attached to the center of the plate 20. The distance sensor 31 may be electrically connected to the control unit 50. The distance between the lamp 10 and the plate 20 sensed by the distance sensor 31 may be transmitted to the control unit 50.

[0025] The drive unit 40 can move the position of the plate 20. The drive unit 40 can be attached to the plate 20. The drive unit 40 can include a plurality of cylinders. The drive unit can include a first cylinder 41 and a second cylinder 42. The first cylinder 41 and the second cylinder 42 can be, for example, pneumatic cylinders driven by air pressure. The first cylinder 41 and the second cylinder 42 can be attached to both ends of the plate 20, respectively. The first cylinder 41 and the second cylinder 42 can be driven to extend or shorten their lengths. The plate 20 can be moved by extending or shortening the lengths of the first cylinder 41 and the second cylinder 42. The plurality of lamps 10 are fixed so that their positions do not move, and the distance between the plate 20 and the plurality of lamps 10 can be controlled by moving the plate 20. For example, when the lengths of the first cylinder 41 and the second cylinder 42 are extended, the distance between the plate 20 and the lamps 10 can be reduced, and when the lengths of the first cylinder 41 and the second cylinder 42 are shortened, the distance between the plate 20 and the lamps 10 can be increased. The lengths of the first cylinder 41 and the second cylinder 42 can be extended or shortened to the same extent. By extending or shortening the lengths of the first cylinder 41 and the second cylinder 42 to the same extent, the plate 20 can control the distance between the lamps 10 while maintaining the gradient. When the distance between the plate 20 and the lamps 10 is controlled by driving the driver 40, the distance between the plate 20 and the lamps 10 sensed by the distance sensor 31 can be changed. The driver 40 can be electrically connected to the controller 50. The driver 40 can be controlled by the controller 50.

[0026] The control unit 50 may be configured to control the operation of the driver 40. The control unit 50 may be electrically connected to the distance sensor 31. The control unit 50 may receive distance data between the plate 20 and the lamp 10 from the distance sensor 31. The control unit 50 may be electrically connected to the driver 40. The control unit 50 may be electrically connected to each of the first cylinder 41 and the second cylinder 42. The control unit 50 may transmit an electrical signal to the driver 40 to control the operation of the driver. The control unit 50 may control the driver 40 based on the distance data between the lamp 10 and the plate 20 sensed by the distance sensor 31. For example, if the distance between the lamp 10 and the plate 20 sensed by the distance sensor 31 is too close, the lamp 10 may be heated by reflected heat from the plate 20, which may cause damage to the lamp. Therefore, the control unit 50 may transmit a feedback signal to the driver 40 and control the operation of the driver 40 so that the driver 40 moves the plate 20 in a direction away from the lamp 10. Since the intensity of the radiant heat from the lamp transmitted to the electrode a varies depending on the position of the plate 20, the control unit 50 can control the driving of the driving unit 40 to set the position of the plate 20 to an optimal position.

[0027] The control unit 50 may include a processor 51 and a user interface 52. The processor 51 may receive and process distance data from the distance sensor 31. The processor 51 may be electrically connected to the distance sensor 31 and the driving unit 40. The user interface may be electrically connected to the processor 51, and may visualize the distance data processed by the processor and display it on a display.

[0028] By adopting this configuration, the user of the heat source device 1 according to the first embodiment of the present invention can not only check the distance between the plate 20 and the lamps 10 in real time, but also significantly reduce the inefficient process that occurs when manually controlling the distance between the plate 20 and the lamps 10. Therefore, damage to the lamps 10 due to an error in the separation distance between the lamps 10 and the plate 20 can be significantly reduced, and further, the position of the plate 20, which must be changed for each drying process of the electrode a, can be controlled by a simple electrical operation.

[0029] FIG. 2 shows the shape of the plate 20 of the heat source device according to the first embodiment of the present invention. Referring to FIG. 2, the plate 20 of the heat source device according to the first embodiment of the present invention may include a plate body 21 and plate holes 22. The plate body 21 may have an overall rectangular shape with a longitudinal direction. The longitudinal direction of the plate body 21 may coincide with the direction in which the plurality of lamps are arranged. The plate body 21 may have plate holes 22 formed therein. A plurality of plate holes 22 may be provided, and at least a portion of the electromagnetic waves from the lamps may pass through the plate holes 22. The size and number of the plate body 21 and the plate holes 22 formed therein may be varied depending on the shape and thickness of the electrodes to be dried.

[0030] Second Embodiment FIG. 3 shows a heat source device 2 according to a second embodiment of the present invention. The second embodiment of the present invention differs from the first embodiment in that it further includes a temperature sensor 32. Details common to the first embodiment will be omitted as much as possible, and the second embodiment will be described focusing on the differences from the first embodiment.

[0032] The lamp 10 can emit electromagnetic waves that generate radiant heat at the electrode a.

The driving unit 40 can include a first cylinder 41 and a second cylinder 42, and can control the separation distance between the plate 20 and the lamp 10 by driving the first cylinder 41 and the second cylinder 42 to shorten or extend their lengths. The control unit 50 can be electrically connected to the sensor unit 30 and the driving unit 40. The control unit 50 can include a processor 51 that processes data sensed by the sensor unit 30 and a user interface 52 that visualizes and displays the processed data.

[0033] The sensor unit 30 may include a distance sensor 31 and a temperature sensor 32. The distance sensor 31 may sense the distance between the plate 20 and the lamp 10. The temperature sensor 32 may sense the surface temperature of the lamp 10. The distance sensor 31 and the temperature sensor 32 may be provided on the plate 20, for example, and fastened to the plate 20. The distance sensor 31 and the temperature sensor 32 may be electrically connected to the control unit 50. The distance sensor 31 and the temperature sensor 32 may be electrically connected to a processor 51 of the control unit 50. The distance sensor 31 and the temperature sensor 32 may transmit the sensed distance data and temperature data, respectively, to the control unit 50. By obtaining surface temperature data of the lamp 10 through the temperature sensor 32, overheating of the surface of the lamp 10 can be detected and addressed in advance. This significantly reduces the risk of damage to the lamp 10. For example, if the sensed temperature of the surface of the lamp 10 is detected as abnormally high, the control unit 50 can control the driving of the driving unit 40 so that the distance between the plate 20 and the lamp 10 increases.
