Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0029] See also Figure 1 and Figure 2 A vacuum infrared heating system 1 provided by an embodiment of the utility model may, for example, include: a housing 100 , a heating target placement table 200 , an infrared heating module 10 , an infrared temperature detection device 20 and a microcontroller 30 .

[0030] Specifically, the housing 100 is formed with a vacuum chamber 101. Figure 2 As shown, the housing 100 may, for example, include a box body 110 and a cover body 120. The cover body 120 may, for example, be movably connected to the box body 110, that is, the cover body 120 may be movably opened relative to the box body 110. When the cover body 120 is covered on the box body 110, a cavity is formed, and then the cavity may be evacuated by, for example, a vacuum pump or other vacuum device to form a vacuum cavity 101. The heating target placement table 200 is disposed in the vacuum cavity 101 and is connected to the housing 100. The heating target placement table 200 may, for example, be fixedly supported in the box body 110. The heating target placement table 200 may, for example, have a placement surface, and the placement surface is used to place the heating target. The heating target may, for example, be an OLED panel, and of course, it may also be other heating targets, and this embodiment is not limited thereto.

Furthermore, the heating target placement platform 200 may be provided with a fixing portion, for example, and the fixing portion is used to fix the heating target on the heating target placement platform 200 to improve stability.

[0031] The infrared heating module 10 can be, for example, disposed in the vacuum chamber 101, and the infrared heating module 10 is disposed on the top of the housing 100. The infrared heating module 10 is disposed opposite to the heating target placement table 200, that is, the infrared heating module 10 is arranged in parallel with the heating target placement table 200, and when the infrared heating module 10 is working, the heating target on the heating target placement table 200 can be heated. In one implementation of the present embodiment, the infrared heating module 10 can be, for example, disposed on the cover 120, and when the cover 120 is opened, the infrared heating module 10 will also move and open, so that the heating target can be placed on the heating target placement table 200. The infrared heating module 10 performs radiant heating, and the infrared heating response is sensitive and the heating efficiency is high.

[0032] The infrared temperature detection device 20 may be, for example, disposed on the outside of the housing 100, and may be, for example, disposed corresponding to the heating target placement table 200, and the infrared temperature detection device 20 may be used to detect the temperature of the heating target. The infrared temperature detection device 20 may specifically be, for example, a non-contact infrared thermometer, and the infrared temperature detection device 20 may be, for example, disposed on the side of the housing 100 away from the vacuum chamber 101, that is, the infrared temperature detection device 20 is disposed on the outside of the housing 100, for example, disposed on the outside of the cover 120. Further, the housing 100 may be, for example, provided with an infrared penetration region 121 corresponding to the infrared temperature detection device 20, and the infrared penetration region 121 may be, for example, a transparent visible region disposed on the housing 100, and the infrared light of the infrared temperature detection device 20 may pass through the infrared penetration region 121 and irradiate the heating target in the vacuum chamber 101 to detect the temperature of the heating target.

[0033] The microcontroller 30 is arranged on the outside of the housing 100, and the microcontroller 30 is electrically connected to the infrared heating module 10 and the infrared temperature detection device 20. The microcontroller 30 can be specifically arranged on the outer surface of the cover 120, for example. The microcontroller 30 can be, for example, a programmable logic controller (PLC) or a microcontroller unit (MCU). Of course, the present embodiment is not limited thereto. The microcontroller 30 can be, for example, electrically connected to the infrared heating module 10 through a thyristor, and the infrared heating module 10 can be controlled to work through the thyristor. The microcontroller 30 can perform infrared band matching according to the infrared absorption wavelength of the heating target to control the infrared heating module 10 to heat, so as to improve the heating speed and efficiency. The microcontroller 30 is used to control the infrared heating module 10 to heat the heating target according to the detection of the infrared temperature detection device. Specifically, the microcontroller 30 may, for example, store the predetermined heating temperature of the infrared heating module 10. After the infrared temperature detection device 20 detects the temperature of the heating target, it may, for example, feed back to the microcontroller 30. The microcontroller 30 determines the real-time temperature of the heating target and the predetermined heating temperature, thereby adjusting the heating temperature of the infrared heating module 10 according to the temperature height to improve the accuracy. The microcontroller 30 may, for example, calculate the difference according to the predetermined heating temperature and the real-time temperature, and then formulate an algorithm according to the heating power and the difference according to the specific curve change law to control the infrared heating module 10 for adjustment.

Moreover, the cooperation of the infrared temperature detection device 20 and the microcontroller 30 can improve the heating accuracy, thereby further improving production efficiency and reducing energy loss.

[0035] See also Figure 3 There is a distance a between the heating target placement table 200 and the infrared heating module 10, and the range of the distance a is 60 to 150 mm. By setting the range of the distance a to 60 to 150 mm, the infrared heating module 10 can meet the radiation heating of the heating target, and the problem of too high heating temperature when the distance is too close and too low heating temperature when the distance is too far can be avoided. In addition, the setting of the distance can avoid collision when the robot moves the heating target.

[0036] See also Figure 2 and Figure 4The infrared heating module 10 may include, for example, a plurality of infrared heating lamps 320 and two mounting seats 310, and the two mounting seats 310 are fixed on the housing 100 at intervals. The infrared heating lamps 320 may be, for example, quartz infrared lamps, which have a sensitive heating response and high heating efficiency. The spacing between the two mounting seats 310 may be, for example, the length of the infrared heating lamps 320, and the plurality of infrared heating lamps 320 are installed between the two mounting seats 310, and the plurality of infrared heating lamps 320 are evenly spaced. In this embodiment, the distance X between two adjacent infrared heating lamp tubes 320 can be set, for example, according to the distance a between the heating target placement table 200 and the infrared heating module 10. The radiation distance Y of the infrared heating module 10 can be, for example, the distance a between the heating target placement table 200 and the infrared heating module 10. The radiation distance Y of the infrared heating module 10 and the distance X between two adjacent infrared heating lamp tubes 320 satisfy Y≥1.5X. The light output angle of the infrared heating lamp tube 320 can be, for example, 60°~80°. Through such a setting, the infrared heating module 10 can have no infrared radiation blind area, thereby further ensuring the uniformity of temperature.

[0037] Furthermore, in one implementation of the present embodiment, a plurality of infrared heating lamp tubes 320 may be electrically connected to a microcontroller 30, for example, so that the microcontroller 30 may individually adjust the temperature of each infrared heating lamp tube 320, thereby reducing the requirements for the consistency of the infrared heating lamp tubes 320 and the differences in the aging speed during use, maintaining consistent heating characteristics, and thus improving the uniformity of the heating temperature.

The number of the backup infrared temperature detection devices 22 may, for example, be one or two, or may be more than one, and may be specifically set according to actual needs. The main infrared temperature detection device 21 and the at least one backup infrared temperature detection device 22 may, for example, be both arranged on the outside of the housing 100, and are electrically connected to the microcontroller 30, respectively. The microcontroller 30 is also used to switch the main infrared temperature detection device 21 and the backup infrared temperature detection device 22 to be in working state. Specifically, the microcontroller 30 may, for example, detect whether the main infrared temperature detection device 21 is in a normal working state. When the main infrared temperature detection device 21 is working abnormally, the microcontroller 30 switches the backup infrared temperature detection device 22 to be in working state.

During the operation of the system, the microcontroller 30 may, for example, detect whether the vacuum infrared heating system 1 is working normally, and control the early warning device to give an early warning when it is detected that the vacuum infrared heating system 1 is working abnormally. Specifically, the microcontroller 30 may, for example, detect whether the temperature of the heating target is abnormal through the infrared temperature detection device 20, and when the temperature deviates, the microcontroller 30 may, for example, control the early warning device 50 to give an early warning.

Of course, this embodiment is not limited to this. The microcontroller 30 can also detect, for example, whether the working current of the infrared heating module 10 is abnormal. When the working current deviates, the microcontroller 30 can, for example, control the early warning device 50 to issue an early warning.

Specifically, the microcontroller 30 can, for example, detect whether the temperature of the heating target is abnormal through the infrared temperature detection device 20. When the temperature deviates, the microcontroller 30 can, for example, control the early warning device 50 to issue an early warning. For example, when the temperature of the heating target deviates greatly, the three-color light in the early warning device 50 turns red and an alarm sounds; when the temperature of the heating target deviates little, the three-color light in the early warning device 50 turns yellow; when the temperature of the heating target is normal, the three-color light in the early warning device 50 turns green.
