[0040] First Embodiment

[0041] Figure 1 is a view showing the heat source device 1 according to the first embodiment of the present invention.

[0042] Reference Figure 1 , the heat source device 1 tested according to the 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.

[0043] The lamp 10 may radiate electromagnetic waves for drying the electrode a. The lamp 10 may generate radiant heat at the electrode a by radiating electromagnetic waves to dry the coating material of the electrode. The lamp 10 may be a mid-infrared (MIR) lamp. The lamp 10 may radiate mid-infrared rays to generate radiant heat at the electrode a. For example, the wavelength of the mid-infrared rays radiated by the lamp 10 may be in the range of 2 μm to 6 μm. The lamp 10 may be provided in plurality. The plurality of lamps 10 may be spaced apart from each other at equal intervals and arranged side by side. The electrode a may be provided on the optical path of the electromagnetic waves radiated by the lamp 10.

[0044] The plate 20 may allow at least some of the electromagnetic waves of the lamp 10 radiated toward the electrode a to pass therethrough. The plate 20 may be provided to adjust the form and luminous intensity of the electromagnetic waves of the lamp 10 radiated toward the electrode a. The plate 20 may be provided between the lamp 10 and the electrode a. Through the structure of the plate 20, it is possible to control the electromagnetic waves of the lamp 10 to reach a specific position of the electrode a that needs to be heat-dried. The plate 20 may be provided parallel to the arrangement direction of the plurality of lamps 10. Plate holes may be provided in the plate 20 to allow at least some of the electromagnetic waves of the lamp 10 to pass therethrough. The shape of the plate 20 will be described in detail with reference to the following Figure 2 to describe the shape of the plate 20 in detail.

[0045] The distance sensor 31 may be configured to detect the distance between the lamp 10 and the plate 20. For example, the distance sensor 31 may be an optical fiber sensor. The optical fiber sensor is flexible and can be bent, allowing the optical fiber sensor to be stably mounted even in a narrow space. The distance sensor 31 may be disposed on the plate 20 to detect the distance between the plate 20 and the lamp 10. For example, the distance sensor 31 may be firmly fastened to the plate 20. The distance sensor 31 may be mounted on the central portion 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 detected by the distance sensor 31 may be transmitted to the control unit 50.

[0046] The driving unit 40 may move the position of the plate 20. The driving unit 40 may be mounted on the plate. The driving unit 40 may include a plurality of cylinders. The driving unit may include a first cylinder 41 and a second cylinder 42. For example, the first cylinder 41 and the second cylinder 42 may be pneumatic cylinders driven by pneumatic pressure. The first cylinder 41 and the second cylinder 42 may be mounted on two end portions of the plate 20. The first cylinder 41 and the second cylinder 42 may be driven to extend or contract their lengths. As the lengths of the first cylinder 41 and the second cylinder 42 extend or contract, the plate 20 may move. Since the plurality of lamps 10 are fixed so that their positions do not move while the plate 20 moves, the spacing distance between the plate 20 and the plurality of lamps 10 can be controlled. For example, when the lengths of the first cylinder 41 and the second cylinder 42 extend, the spacing distance between the plate 20 and the lamp 10 can be reduced, and when the lengths of the first cylinder 41 and the second cylinder 42 contract, the spacing distance between the plate 20 and the lamp 10 can be increased. The lengths of the first cylinder 41 and the second cylinder 42 may be extended or contracted to the same extent. Since the lengths of the first cylinder 41 and the second cylinder 42 can be extended or contracted to the same extent, the spacing distance between the plate 20 and the plurality of lamps 10 can be controlled while maintaining the inclination of the plate 20. When the spacing degree between the plate 20 and the lamp 10 is controlled by driving the driving unit 40, the distance between the plate 20 and the lamp 10 detected by the distance sensor 31 may be changed. The driving unit 40 may be electrically connected to the control unit 50. The driving of the driving unit 40 may be controlled by the control unit 50.

[0047] The control unit 50 can be used to control the driving of the driving unit 40. The control unit 50 can be electrically connected to the distance sensor 31. The control unit 50 can receive data regarding the distance between the plate 20 and the lamp 10 from the distance sensor 31. The control unit 50 can be electrically connected to the driving unit 40. The control unit 50 can be electrically connected to the first cylinder 41 and the second cylinder 42. The control unit 50 can transmit an electrical signal to the driving unit 40 to control the driving of the driving unit 40. The control unit 50 can control the driving unit 40 based on data related to the distance between the lamp 10 and the plate 20 detected by the distance sensor 31. For example, when the distance between the lamp 10 and the plate 20 detected by the distance sensor 31 is too small, since the lamp 10 may be heated due to the heat reflected by the plate 20, the lamp may be damaged. Thus, the control unit 50 can transmit a feedback signal to the driving unit 40 to control the driving of the driving unit 40 so that the driving unit 40 moves the plate 20 in a direction away from the lamp 10. Since the intensity of the radiant heat of the lamp transmitted to the electrode a varies according to the position of the plate 20, the control unit 50 can control the driving of the driving unit 40 so that the plate 20 is set to the optimal position.

[0048] The control unit 50 can include a processor 51 and a user interface 52. The processor 51 can receive and process the distance data from the distance sensor 31. The processor 51 can be electrically connected to the distance sensor 31 and the driving unit 40. The user interface can be electrically connected to the processor 51 and can visualize and display the distance data processed by the processor and the like through a display.

[0049] By adopting such a structure, 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 lamp 10 in real time, but also significantly reduce the inefficiency of the process that occurs when manually controlling the distance between the plate 20 and the lamp 10. Therefore, the damage to the lamp 10 caused by the error in the spacing distance between the lamp 10 and the plate 20 can be significantly reduced. Additionally, the position of the plate 20 that should be changed for each drying process of the electrode a can be controlled by simple electrical manipulation.

[0050] Figure 2 is a view showing the shape of the plate 20 of the heat source device according to the first embodiment of the present invention.

[0051] Reference Figure 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 outer portion of the plate body 21 may be formed in a longitudinal rectangular shape. The length direction of the plate body 21 may be consistent with the direction in which the plurality of lamps are arranged. The plate holes 22 may be formed in the plate body 21. The plate holes 22 may be provided in plurality, and at least some of the electromagnetic waves of the lamp may pass through the plate holes 22. The sizes and the number of the plate body 21 and the plate holes 22 formed in the plate body 21 may be changed according to the shape and thickness of the electrode to be dried.

[0052] Second Embodiment

[0053] Figure 3 is a view showing a heat source device 2 according to the second embodiment of the present invention.

[0054] The second embodiment of the present invention is different from the first embodiment in that the second embodiment further includes a temperature sensor 32. The common content with the first embodiment will be omitted as much as possible, and the content of the second embodiment, which mainly describes the content different from the first embodiment, will be described.

[0055] Reference Figure 3 , the heat source device 2 according to the second embodiment of the present invention may include a lamp 10, a plate 20, a sensor unit 30, a driving unit 40, and a control unit 50.

[0056] The lamp 10 may radiate electromagnetic waves to generate radiant heat at the electrode a. The plate 20 may be disposed between the lamp 10 and the electrode a, and may allow at least some of the electromagnetic waves radiated by the lamp 10 to pass therethrough toward the electrode a. The driving unit 40 may include a first cylinder 41 and a second cylinder 42, and as the first cylinder 41 and the second cylinder 42 are driven to shorten or extend their lengths, the distance between the plate 20 and the lamp 10 may be controlled. The control unit 50 may be electrically connected to the sensor unit 30 and the driving unit 40. The control unit 50 may include a processor 51 and a user interface 52. The processor 51 processes the data detected by the sensor unit 30, and the user interface 52 visualizes and displays the processed data.

[0057] The sensor unit 30 may include a distance sensor 31 and a temperature sensor 32. The distance sensor 31 may detect the distance between the plate 20 and the lamp 10. The temperature sensor 32 may detect the surface temperature of the lamp 10. For example, the distance sensor 31 and the temperature sensor 32 may be disposed on the plate 20 and firmly 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 the processor 51 of the control unit 50. The distance sensor 31 and the temperature sensor 32 may respectively transmit the detected distance data and temperature data to the control unit 50. By using the surface temperature data of the lamp 10 obtained through the temperature sensor 32, overheating of the surface of the lamp 10 can be detected and responded to in advance. Therefore, damage to the lamp 10 can be significantly reduced. For example, when the detected temperature of the surface of the lamp 10 is abnormally high, the control unit 50 may control the driving of the driving unit 40 so that the distance between the plate 20 and the lamp 10 increases.

[0058] Third Embodiment

[0059] Figure 4 is a view showing the heat source device 3 according to the third embodiment of the present invention.

[0060] The third embodiment of the present invention is different from the second embodiment in that the third embodiment further includes a housing portion 60 and a hot air blower 70. The common content with the second embodiment will be omitted as much as possible, and the content of the third embodiment that is different from the second embodiment will be mainly described.

[0061] Reference Figure 4 Referring to, the heat source device 3 according to the third embodiment of the present invention may include a lamp 10, a plate 20, a sensor unit 30, a driving unit 40, a control unit 50, the housing portion 60, and the hot air blower 70.

The control unit 50 can be provided outside the housing part 60.

[0063] The hot air blower 70 can be arranged to communicate with the internal space of the housing part 60. The hot air blower 70 can communicate with the internal space of the housing part 60 through a duct 71. As the hot air blower 70 forcibly blows high-temperature air into the internal space of the housing part 60, the hot air blower 70 can operate as a heat source for drying the coated electrode a together with the plurality of lamps 10.
