For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] In the related art, in the production of vacuum insulation panels, generally, a core material for heat insulation and an adsorbent are loaded into a bagged barrier film. After vacuum heat sealing, the vacuum insulation panel is heat treated at a temperature of 100 to 150 °C to complete the sealing of the barrier film. However, for the vacuum insulation panel processed by the high-temperature hot melting method, its sealing quality is poor, and it is easy to cause air leakage at the sealing position.

[0035] The following describes the present application in conjunction with the attached Figures 1 - 3 and with reference to specific embodiments:

[0036] Please refer to Figures 1 to 2 , an embodiment of the present utility model provides a packaging device for a vacuum insulation panel, including a base 100 and a radiation heater 200. A processing position 110 is provided on the base 100, and the processing position 110 is adapted to fix the vacuum insulation panel 300; a radiation area is formed on one side of the radiation heater 200, and the radiation area at least covers the processing position 110.

[0037] The radiation heater 200 generates electromagnetic waves, and through the propagation of the electromagnetic waves, high-energy heat is generated in the radiation area; the electromagnetic waves can effectively penetrate the barrier film and heat the barrier film, improving the sealing quality and avoiding air leakage at the sealing position. The radiation area formed by the radiation heater 200 at least covers the processing position 110, and the barrier film on the processing position 110 can be heated to improve the sealing quality of the barrier film.

[0038] The performance of the vacuum insulation panel 300 depends on its highly vacuum state inside. Performing the packaging work in a vacuum environment can enable the vacuum insulation panel 300 to maintain a high vacuum. However, since there are no gas or liquid molecules in a vacuum to transfer heat, traditional convective and conductive heating methods will not work, which is not conducive to the processing of the vacuum insulation panel 300 in a vacuum environment. In the embodiment of the present utility model, the radiation heater 200 is used to generate electromagnetic waves. The electromagnetic waves propagate at the speed of light and can penetrate air or vacuum. They are absorbed or reflected on the surface of an object. The electromagnetic waves are waves propagated through an electric field and a magnetic field and do not rely on a medium to transfer heat. They can also effectively transfer energy to the surface of an object in a vacuum; therefore, using the radiation heater 200 to heat the barrier film is beneficial to the sealing effect of the vacuum insulation panel 300 in a vacuum environment.

[0039] By sending electromagnetic waves from the radiation heater 200 to the radiation area, the inside of the radiation area is uniformly heated, avoiding the problem of poor sealing effect caused by uneven heating in the traditional heat conduction method. After the electromagnetic wave energy is absorbed by the molecules on the surface of an object, it will quickly cause an increase in molecular vibration, thereby raising the overall temperature. Radiation heating can directly transfer energy to the surface of an object, featuring fast heating, high efficiency, and high energy utilization rate.

[0040] In the related art, the barrier film is heat-sealed by high-temperature heating. Due to the heat convection generated by the high temperature, the core material is inevitably heated, which easily causes the aging of the core material and reduces the quality of the finished product.

[0041] Please refer to Figures 1 to 3 , in some embodiments, the encapsulation device further includes a blocking member 400. The blocking member 400 is located between the processing position 110 and the radiation heater 200, and the blocking member 400 can cover a part of the vacuum insulation panel 300.

[0042] During encapsulation, the vacuum insulation panel 300 is fixed at the processing position 110, and the blocking member 400 is located between the processing position 110 and the radiation heater 200, so that the blocking member 400 can block a part of the vacuum insulation panel 300, and can heat the sealing position, improve the sealing quality, and reduce the risk of the core material being aged by the thermal influence.

[0043] Please refer to Figure 1 , in some embodiments, along the direction from the radiation heater 200 to the processing position 110 (such as Figure 1 the a direction in

[0044] ), the area of the orthographic projection of the blocking member 400 on the processing position 110 is smaller than the area of the orthographic projection of the vacuum insulation panel 300 on the processing position 110.

[0045] It should be noted that the blocking member 400 can be plate-shaped to reduce the material consumption, and the thickness of the blocking member 400 can be set according to actual needs; in other embodiments, the blocking member 400 can also be block-shaped; the shape and size of the blocking member 400 can be set according to the shape and size of the vacuum insulation panel 300, and the embodiments of the present invention do not particularly limit the shape and size of the blocking member 400.

[0046] Please refer to Figure 2 , in some embodiments, the distance between the edge of the blocking member 400 and the edge of the vacuum insulation panel 300 is less than five millimeters.

[0047] Generally, the vacuum insulation panel 300 needs to be sealed at its edge position; the distance between the edge of the blocking member 400 and the edge of the vacuum insulation panel 300 is less than five millimeters, which can maximize the protection of the vacuum insulation panel 300 while ensuring the smooth progress of the encapsulation work, and reduce the influence of the core material by thermal radiation.

[0048] Since the hot melt method with high-temperature heating cannot perform targeted heating, for profiled vacuum insulation panels and vacuum insulation panels with holes and grooves, the entire vacuum insulation panel is usually hot melt encapsulated, and then, a secondary sealing is performed by local hot melting, which easily causes the vacuum insulation panel to age and results in poor sealing quality.

[0049] Please refer to Figure 2 , in some embodiments, the blocking member 400 is provided with an avoidance portion 410 corresponding to the hole groove 310 of the vacuum insulation panel 300. The electromagnetic wave emitted by the radiation heater 200 can directly act on the barrier film at the position of the hole groove of the vacuum insulation panel 300 through the avoidance portion 410, and the barrier film at the position of the hole groove 310 of the vacuum insulation panel 300 can be locally heated to achieve local sealing of the vacuum insulation panel 300.

[0050] It can be understood that when the radiation heater 200 operates, electromagnetic waves are emitted to the vacuum insulation panel 300 located at the processing position 110. A part of the electromagnetic waves irradiate on the edge position of the vacuum insulation panel 300, a part of the electromagnetic waves pass through the avoidance portion 410 and irradiate on the hole groove 310 of the vacuum insulation panel 300, and a part of the electromagnetic waves irradiate on the blocking member 400 and are absorbed or reflected by the blocking member 400; in the embodiment of the present invention, through the blocking member 400 and the radiation heater 200, in the case of one-time heating, the sealing of the edge position and the hole groove position of the vacuum insulation panel 300 is satisfied at the same time, without the need for multiple heating, reducing the damage to the core material during the encapsulation process; and the blocking member 400 can block most of the electromagnetic waves, and without affecting the encapsulation work, the core material is prevented from aging due to the influence of thermal radiation.

[0051] Please refer to Figure 2 , in some embodiments, the area of the avoidance portion 410 is larger than the area of the hole groove 310 of the vacuum insulation panel 300, so that the barrier film at the hole groove position of the vacuum insulation panel 300 can be exposed to the radiation to perform local sealing for the hole groove position of the vacuum insulation panel 300.

[0052] Please refer to Figure 2 , in some embodiments, the distance between the edge of the avoidance portion 410 and the edge of the hole groove 310 of the vacuum insulation panel 300 is less than five millimeters. Under the condition of ensuring the smooth progress of the local encapsulation work, the vacuum insulation panel 300 can be maximally protected, and the influence of thermal radiation on the core material is reduced.

[0053] In some embodiments, the barrier 400 forms a reflective surface on the side facing the radiation heater 200. When electromagnetic waves irradiate on the barrier 400, the reflective surface can reflect the electromagnetic waves, preventing the electromagnetic waves from acting on the core material, maximizing the isolation between the core material and the electromagnetic waves, and avoiding the core material from being affected by high temperatures. The barrier 400 can be a reflector; in other embodiments, a reflective film or the like can also be provided on the side of the barrier 400 facing the radiation heater 200 to reflect the electromagnetic waves.

[0054] In some embodiments, the radiation heater 200 is an infrared heater that reflects infrared radiation to achieve a heat-melting effect on the barrier film; the infrared radiation is in the spectral range between visible light and microwaves, with moderate energy, which can penetrate the barrier film well and also has sufficient energy for heating the barrier film. Moreover, infrared radiation heating is a mild heating method that will not cause thermal shock or thermal deformation on the surface of the object, and has less impact on the physical properties of the heating object. Through the infrared radiation heater 200, the size of the radiation area and the heating intensity can be precisely controlled, and the radiation power and radiation time can be adjusted according to requirements to achieve a more precise heating effect.

[0055] Please refer to Figure 3 , in some embodiments, the radiation heater 200 includes a lamp tube 210, and the lamp tube 210 is fixed to the base 100; due to the tube shape of the lamp tube 210, the electromagnetic waves emitted by the lamp tube 210 have a sufficient coverage range in its length direction to improve the working range of the radiation heater 200; the lamp tube 210 is fixed through the base 100 to ensure the stable progress of the encapsulation work; the size of the lamp tube 210 in its length direction is greater than the size of the vacuum insulation panel 300 in the length direction of the lamp tube 210 to ensure that all positions of the vacuum insulation panel 300 are within the working range of the lamp tube 210. For example, the size of the vacuum insulation panel 300 in the length direction of the lamp tube 210 is twenty centimeters, correspondingly, the length of the lamp tube 210 needs to be greater than twenty centimeters, and the length of the lamp tube 210 can be twenty-five centimeters, thirty centimeters, etc.

[0056] Please refer to Figure 3 , in some embodiments, the radiation heater 200 includes a bracket 220, and at least two lamp tubes 210 are provided. Each lamp tube 210 is arranged and fixed on the bracket 220.

[0057] By providing multiple lamp tubes 210, the working range of the radiation heater 200 is improved; the bracket 220 can fix the multiple lamp tubes 210 and maintain the relative positions between the multiple lamp tubes 210 unchanged. By adjusting the heating intensity of the multiple lamp tubes 210 and limiting the distance between each lamp tube 210, the radiation heater 200 can heat evenly.

[0058] Please refer to Figures 1 to 2, in some embodiments, the base 100 is a vacuum chamber, and the radiation heater 200 is disposed inside the vacuum chamber, which is conducive to the encapsulation of the vacuum insulation panel 300 in a vacuum environment and can maintain the high-vacuum state of the vacuum insulation panel 300.

[0059] The vacuum chamber can play a fixing role for the vacuum insulation panel 300. At the same time, it can provide a vacuum environment for the vacuum insulation panel 300, enabling the vacuum insulation panel 300 to be sealed in a vacuum environment without external equipment. In addition, the structure of the vacuum chamber is relatively airtight, which can reduce the heat dissipation of the radiation heater 200 and improve the energy utilization rate.

[0060] Generally, the vacuum chamber includes a vacuum pump, and the inside of the chamber 120 can be made to form a vacuum state through the vacuum pump.

[0061] Please refer to Figures 1 to 2 , in some embodiments, the vacuum chamber includes a chamber 120 and a chamber cover. The processing position 110 is located at the bottom of the chamber 120, and the radiation heater 200 is disposed on the chamber cover. During operation, the vacuum insulation panel 300 is fixed inside the chamber 120, the chamber cover is covered, and the radiation heater 200 can act on the vacuum insulation panel 300 to achieve encapsulation.
