[0034] The application provides an experimental online thermal curing evaluation device 100, which is mainly used for online evaluation of sensitive material characteristics, so as to evaluate and adjust the performance of the sensitive material in the thermal curing process in the experimental stage. Here, the sensitive material includes but is not limited to polyimide material, high-purity slurry, passivation coating and the like.

[0035] Please refer to Figures 1 to 8 The experimental online thermal curing evaluation device 100 includes a box body 10, a box door 20, a tray 30, a controllable atmosphere mechanism 40 and an infrared heat source 50: the inside of the box body 10 is provided with a containing cavity 11, the containing cavity 11 has a plurality of side walls 12, one of the side walls 12 is provided with a first opening 13, the first opening 13 is in communication with the inside of the containing cavity 11; and the box body 10 is also provided with an interface 14 which is in communication with the containing cavity 11 and is used for inputting or outputting gas. The box door 20 is installed on one side of the box body 10 which has the first opening 13 and can rotate relative to the box body 10 to open or close the first opening 13; the tray 30 is contained in the containing cavity 11 and is used for carrying the material to be evaluated; the controllable atmosphere mechanism 40 is connected with the interface 14 and is used for controlling the gas content in the containing cavity 11. Here, the gas can be oxygen, or special inert gases such as nitrogen and argon. The infrared heat source 50 is configured in multiple numbers and is used for emitting infrared rays; wherein the plurality of side walls 12 are arranged around the tray 30, and at least one infrared heat source 50 is arranged on each side wall 12, so that the heat emitted by the infrared heat source 50 is surrounded at the circumferential position of the tray 30. It can be understood that, by arranging the infrared heat source 50, the infrared rays emitted by the infrared heat source 50 penetrate into the sensitive material, causing molecular vibration and chemical reaction and realizing synchronous heating inside and outside, so as to avoid thermal gradient leading to over-curing of the surface of the sensitive material. At the same time, at least one infrared heat source 50 is arranged on each side wall 12, so that the heat emitted by the infrared heat source 50 is surrounded at the circumferential position of the tray 30, a three-dimensional surrounding heating space is constructed, the heating of the sensitive material is more uniform, and local overheating or insufficient thermal curing of the sensitive material is avoided; secondly, the infrared heat source 50 has a fast heating speed and a high heating rate, so that the containing cavity 11 can quickly rise to a preset temperature, and the thermal curing efficiency is improved. In combination with the controllable atmosphere mechanism 40, the content of various gases (oxygen, inert gas) in the containing cavity 11 can be changed and controlled, so as to construct different thermal curing environments and realize specific processing requirements of different sensitive material systems (such as liquid / slurry / film / chip).

That is, the experimental online thermosetting evaluation device 100 provided in this application has an external dimension with a height H less than or equal to 1.8m and a width D less than or equal to 1.1m. Thus, compared to commercially available experimental infrared curing ovens (mostly fixed, large, and heavy systems), this application is compact and lightweight, making it more suitable for deployment in laboratories and pilot-scale (intermediate testing) spaces.

Infrared heat sources 50 are provided on the first sidewall 111, second sidewall 112, fourth sidewall 114, sixth sidewall 116, and the side of the door 20 facing the interior of the accommodating cavity 11. Thus, at least five sidewalls 12 of the accommodating cavity 11 have infrared heat sources 50, meaning heat sources are present around the tray 30, as well as at the bottom or top, thereby forming multi-point, multi-angle temperature control and achieving highly uniform heating.

[0042] As preferred, the sixth side wall 116 can also be provided with the infrared heat source 50, so that each side wall 12 of the accommodating cavity 11 is provided with the infrared heat source 50, so that the tray 30 can be fully covered by the infrared heat source 50, and the uniformity of heating is further improved.

[0050] Further, the box body 10 is also provided with a baffle 17, the baffle 17 and the box body 10 form a containing space 171, and the wire hole 15 is located in the containing space 171, so that the wire hole 15 is shielded and protected by the baffle 17.

[0051] Preferably, the baffle 17 and the box body 10 are connected by a detachable manner.

[0052] Alternatively, the baffle 17 and the box body 10 can be detachably connected by a threaded member or a buckle member. It should be noted that the threaded member can be a bolt or a screw, etc.

Further, a sealing ring is arranged at the box door 20 and / or the first opening 13, when the box door 20 is rotated relative to the box body 10 and closes the first opening 13, the box door 20 and the box body 10 can be sealed and connected by the sealing ring, so as to avoid the heat in the containing cavity 11 from being lost through the first opening 13.

[0056] Further, the box door 20 can be provided with a lock catch, when the box door 20 is closed, the lock catch can be locked to the box body 10, so as to avoid the first opening 13 from being passively opened due to the internal pressure of the internal containing cavity 11 or the misoperation of external personnel, etc., so as to affect the quality of sensitive material evaluation.

[0057] Here, the lock catch 21 can be an electronic lock or a mechanical lock.

[0058] Please refer to Figures 5 to 7The controllable atmosphere mechanism 40 is mainly used for controlling the flow of nitrogen, argon or special inert gas into the accommodating cavity 11 through the interface 14, and the positive pressure flow and vacuum pumping in the accommodating cavity 11, so that the oxygen content in the accommodating cavity 11 is controlled to be less than or equal to 20 ppm, so that the environment is more suitable for the processing of oxygen-sensitive materials.

[0059] In an embodiment, the controllable atmosphere mechanism 40 includes at least a first sensor 41 and a second sensor 42, both of which are installed in the accommodating cavity 11.

When it is necessary to control the content of inert gas, the electric valve on the first pipeline is opened, and the inert gas generator inputs inert gas into the accommodating cavity 11 through the second pipeline and the interface.

[0061] In an embodiment, the infrared heat source 50 is configured as an infrared heating lamp tube, and the wavelength band of the infrared heating lamp tube is configured as medium wave and / or far wave. In this way, the infrared heat source 50 can effectively penetrate into the sensitive material for heat curing and improve the heat curing effect.

Specifically, the wavelength of the infrared heat source 50 can be 3 microns, 4 microns, 5 microns, 6 microns, 7 microns, 8 microns, 9 microns, 10 microns, 11 microns, 12 microns, 13 microns, 14 microns, etc. Of course, it is not limited to this, and the wavelength of the infrared heat source 50 can also be set according to actual needs.

[0063] Please refer to Figure 4 , the experimental online heat curing evaluation device 100 also includes a sliding mechanism 60 installed in the accommodating cavity 11, and the tray 30 is arranged on the sliding mechanism 60 and can be slid out of or into the accommodating cavity 11 under the driving of the sliding mechanism 60. In this way, the tray 30 can be easily slid out of and into the accommodating cavity 11, thereby facilitating the user to operate the tray 30.

[0064] Specifically, the sliding mechanism 60 comprises a sliding rail 61, a sliding block 62 and a mounting seat 63, the first opening 13 is located on the side wall 12 of the accommodating cavity 11 in the width direction Y of the box body 10; the sliding rail 61 extends along the width direction Y of the box body 10 and is installed on the side wall 12, the sliding block 62 is in sliding cooperation with the sliding rail 61, and the mounting seat 63 is installed on the sliding rail 61; wherein the tray 30 is installed on the mounting seat 63. When it is needed to take and place the sensitive material, the box door 20 can be opened first, and then the tray 30 is pulled, and under the action of external force, the tray 30 drives the sliding block 62 to move along the sliding rail, so as to realize that the tray 30 slides out of or into the accommodating cavity 11 through the first opening 13.

[0065] Further, the number of the sliding rails 61 is two, the two sliding rails 61 are arranged at intervals in the length direction X of the box body 10, and the mounting seat 63 is connected with the two sliding rails 61 through the sliding block 62. Moreover, in the height direction Z of the box body 10, the sliding rail 61 is installed on the bottom side wall 12 of the accommodating cavity 11.

[0066] As preferred, a handle 64 is arranged on one side of the mounting seat 63 at the first opening 13. In this way, the handle 64 can facilitate the operator to push and pull the mounting seat 63.

[0067] Please refer to Figure 1 、 Figure 2 and Figure 5 , the experimental online heat curing evaluation device 100 further comprises an observation window 70 and a sealing cover plate 80; the observation window 70 is opened on the box body 10, a high-temperature-resistant transparent plate 71 is arranged at the observation window 70, and the high-temperature-resistant transparent plate 71 can block and seal the observation window 70. The sealing cover plate 80 is movably connected between the box body 10 and is used to open and close the observation window 70. It can be understood that by arranging the observation window 70, the operator can detect the heat curing process of the sensitive material from the visual angle in real time without affecting the heat curing process, and observe the sample morphology, color change, foaming, desorption and other states, so as to adjust and control the heat curing process parameters in time based on the window effect. At the same time, the observation window 70 is sealed by the sealing cover plate 80, of course, when the user does not need to observe, the sealing cover plate 80 can be covered on the observation window 70, so as to avoid the heat in the accommodating cavity 11 from flowing out through the observation window 70. When the user needs to observe, the sealing cover plate 80 can be opened and the current heat curing state of the sensitive material in the accommodating cavity 11 can be observed through the high-temperature-resistant transparent plate 71, and the use is more convenient.

[0068] Further, in the height direction Z of the box body 10, the observation window 70 is arranged at the top of the box body 10. In this way, the operator can observe the change of the sensitive material from the overhead angle, so that the visual range is wider and the use and observation are more convenient.

[0069] The high-temperature-resistant transparent plate 71 can be a quartz glass, a high-silica glass, or the like.

[0070] Please continue to refer to Figure 1 The sealing cover plate 80 is rotatably connected to the box body 10 by a hinge. This structure is simple, low in cost, and convenient to use. Alternatively, the sealing cover plate 80 is rotatably connected to the box body 10 by a rotating shaft.

[0071] Further, as shown in Figure 8 The sealing cover plate 80 includes a main body 81 and a heat-insulating layer 82. The main body 81 is movably connected to the box body 10, and the heat-insulating layer 82 is arranged in the main body 81 to improve the heat-insulating effect of the main body 81. Here, the heat-insulating layer 82 is made of a heat-insulating sensitive material, such as a ceramic fiber blanket, a polycrystalline alumina fiber, a chromium-containing fiber blanket, or the like.

[0072] The sealing cover plate 80 is provided with a handle 83. Here, the handle 83 is used for an operator to hold to control the opening and closing of the sealing cover plate 80 to the observation window 70. It should be explained that the form of the handle 83 is not limited, which can be a groove, a protrusion, or a similar door handle, which is not limited here.

[0073] In an embodiment, the experimental online heat curing evaluation device 100 further includes an illuminating lamp arranged in the accommodating cavity 11 to illuminate the inside of the accommodating cavity 11, thereby facilitating the observer to observe the change of the sensitive material through the high-temperature-resistant transparent plate 71.

[0074] Here, the illuminating lamp can be a constant light, or the switch of the illuminating lamp can be associated with the opening and closing of the sealing cover plate 80, that is, when the sealing cover plate 80 is opened, the illuminating lamp is turned on; when the sealing cover plate 80 is closed, the illuminating lamp is turned off. Specifically, the opening and closing of the sealing cover plate 80 can be detected by a sensor, and then the signal of the sensor is used to control the switch of the illuminating lamp. At the same time, since the inside of the accommodating cavity 11 is a high-temperature environment, the illuminating lamp is also selected to be a high-temperature-resistant lamp.

[0075] Please continue to refer to Figures 1 to 3 The experimental online heat curing evaluation device 100 further includes a caster 200 arranged at the bottom of the box body 10 in the height direction Z of the box body 10.
