Description

Technical Field

[0001] The present invention relates to the technical field of vacuum insulation materials, and in particular to a processing device and a processing method for a vacuum insulation panel. Background Art

[0002] The information provided in this section is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] Based on the principle of vacuum insulation, a vacuum insulation panel reduces convective and radiative heat transfer by maximizing the vacuum degree inside the panel and filling it with a core insulation material. It has now been widely used in refrigerators, water heaters, cold storages, building construction, etc.

[0004] In related technologies, the core material of a vacuum insulation panel is prone to continuous outgassing after encapsulation, and it cannot be removed by the adsorbent in the insulation panel, resulting in an increase in the internal pressure of the vacuum insulation panel and a decrease in its insulation performance. Therefore, how to reduce the possibility of continuous outgassing occurring after encapsulation of the core material, so as to improve the insulation performance of the vacuum insulation panel, is an important research direction in the production technology of vacuum insulation panels.

[0047] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms.

[0050] A vacuum insulation panel is a thermal insulation material that is widely used in thermal insulation fields such as refrigerators, freezers, and cold chains. A vacuum insulation panel usually consists of a core material, a film material, a desiccant, and a getter. The core material used in the vacuum insulation panel usually has a porous structure, and the material has a relatively high surface energy and is extremely easy to adsorb gas molecules and water in the air. Therefore, in order to keep the inside of the panel in a low-pressure state for a long time, the core material must be heated and baked to remove gas before encapsulation.

[0051] In related technologies, usually after heating and baking to remove gas, the core material with the desiccant is transferred to a vacuum packaging device for packaging. During this process, the exposure time of the core material and the desiccant in the air usually exceeds 5 minutes, resulting in a large amount of gas and water adsorbed by the core material and the desiccant, greatly reducing the previous degassing effect and the subsequent adsorption performance of the desiccant. Moreover, this will cause the core material to have a continuous outgassing phenomenon after encapsulation. Since the previous adsorption performance of the desiccant is reduced, it cannot well adsorb the outgassing of the core material, resulting in an increase in the internal pressure of the vacuum insulation panel and a decrease in the insulation performance.

[0052] In view of this, the embodiments of the present application provide a processing device and a processing method for a vacuum insulation panel. By integrating heating and baking to remove gas and vacuum packaging in a vacuum chamber, the exposure time of the core material and the desiccant in the air is reduced, thereby reducing the adverse effects of the atmospheric environment and personnel operation fluctuations on the degassing of the production of vacuum insulation panels, improving the degassing effect and performance of the vacuum insulation panel, and at the same time improving the production efficiency.

[0053] The following Figures 1-8 introduces the processing device for the vacuum insulation panel of the present application.

[0054] Combined with the Figure 1 and the Figure 2 shown, the embodiments of the present application provide a processing device 100 for a vacuum insulation panel, which includes a vacuum chamber 10, a heating device 20, and a packaging device 30.

[0055] The vacuum chamber 10 has a sealed and evacuated space. For example, the vacuum chamber 10 may include a box structure, and the box material needs to have good sealing performance and pressure resistance. For example, stainless steel, aluminum, or other alloy materials can be selected. The box has one or more openable and closable doors (not shown in the figure) to facilitate the entry and exit of the core material 200. After the core material 200 enters the box, the inside of the box is evacuated by a vacuum pump to form the vacuum chamber 10. It should be noted that the "vacuum" described in this embodiment is not an absolute vacuum environment, but an environment where the gas pressure in the space after evacuation is much lower than the atmospheric pressure, but there are still some gas molecules.

[0056] Of course, in addition to the box structure, the vacuum chamber 10 can also be a relatively fixed working chamber or room that can perform vacuum pumping operations, and this embodiment will not describe it in detail.

[0057] In this embodiment, the heating device 20 and the encapsulation device 30 are both installed inside the vacuum chamber 10. The heating device 20 is used to heat the core material 200, thereby performing degassing treatment on the core material 200. Heating and degassing can effectively remove volatile gases and moisture in the core material 200. Because if these gases and moisture are not removed, they will gradually be released in the vacuum environment, affecting the thermal insulation performance of the vacuum insulation panel. By heating and degassing, the gas content in the core material 200 can be significantly reduced, and the gas release of the core material 200 in the vacuum environment can be reduced, which is very important for maintaining the performance of the vacuum insulation panel and extending its service life. In addition, heating the core material 200 can also remove pollutants such as grease on the surface of the core material 200, which is beneficial to subsequent vacuum encapsulation.

[0058] The encapsulation device 30 of this embodiment is used to package the protective film 300 onto the heated core material 200, thereby realizing the encapsulation of the core material 200. The encapsulated vacuum insulation panel can maintain a high vacuum degree inside the panel for a long time, thereby ensuring its heat insulation performance. The protective film 300 can effectively isolate the penetration of external air and water vapor, protect the core material 200 from the influence of environmental humidity and temperature changes, avoid heat conduction caused by the movement of gas molecules, enhance the structural stability of the panel, and extend its service life. At the same time, it also helps to improve energy efficiency and reduce energy consumption, making the vacuum insulation panel an efficient thermal insulation material.

[0059] When the heating device 20 heats the core material 200 and the heating device 20 and the encapsulation device 30 are independent structures, the core material 200 can be transferred from the heating device 20 to the encapsulation device 30 for encapsulation operations manually or mechanically. When the heating device 20 and the encapsulation device 30 are integrated as described below, heating and encapsulation can be directly performed at the same station.

[0060] Different from the processing equipment 100 and processing methods of traditional vacuum insulation panels, in this embodiment, the heating device 20 and the encapsulation device 30 are integrated into a vacuum chamber 10. The heating degassing and encapsulation of the core material 200 are carried out in the vacuum environment of the vacuum chamber 10. There is no need to transfer the core material 200, which not only improves the operation efficiency, but also avoids the core material 200 adsorbing gases and water after heating degassing and being exposed to the air, reducing the possibility of continuous gas release after the core material 200 is encapsulated, enabling the internal pressure of the vacuum insulation panel to be in a low-pressure state for a long time, thereby improving the thermal insulation performance of the encapsulated core material 200.

[0061] In some examples, optionally, the heating device 20 of the present embodiment includes a first heating component 21, which is used to heat and degas the core material 200, and the first heating component 21 includes a first surface and a second surface opposite to each other, and the first surface is used to place the core material 200 and heat the core material 200.

[0062] In some embodiments, the first surface of this embodiment may be the upper surface of the first heating component 21, the second surface may be the lower surface of the first heating component 21, and the second surface may be directly connected to the bottom wall of the vacuum chamber 10 or indirectly connected through an intermediate structure.

[0063] The first heating component 21 is used to heat and degas the core material 200 placed thereon, which has a simple structure and is easy to implement. The heating method of the first heating component 21 can be electric heating, infrared heating, microwave heating, etc. As long as the heating method can be performed in a vacuum environment, it is within the optional range of this embodiment.

[0064] Based on the above-mentioned first heating component 21 , in order to further improve the heating efficiency and heating effect, this embodiment further improves the heating device 20 .

[0065] In some examples, optionally, the heating device 20 of this embodiment further includes a second heating component 22, which is disposed facing the first surface. In some embodiments, the second heating component 22 may be located directly above the first heating component 21, and the side of the second heating component 22 facing the first surface has a third surface (the lower surface in the figure), and a gap greater than or equal to the thickness of the core material 200 is formed between the third surface and the first surface.

[0066] The third surface can heat the core material 200 located between the first heating component 21 and the second heating component 22. Specifically, the second heating component 22 can directly heat the upper surface of the core material 200, and the first heating component 21 can directly heat the lower surface of the core material 200. The heat can be transferred to the inside of the core material 200, thereby achieving a degassing effect.

[0067] Compared with the structure having only the first heating component 21 , the heating device 20 configured with both the first heating component 21 and the second heating component 22 has better heating efficiency and heating effect, thereby improving the degassing effect of the core material 200 .

[0068] The structure of the second heating component 22 of this embodiment may also be the same as or similar to the aforementioned first heating component 21. For example, the second heating component 22 may be one of an electric heating component, an infrared heating component, and a microwave heating component.

[0069] In order to further improve the heating effect of the second heating component 22, in some examples, optionally, the heating device 20 further includes a first movable component 23. The first movable component 23 of this embodiment can be installed on the top wall or side wall of the vacuum chamber 10. The first movable component 23 is connected to the second heating component 22 and is used to drive the second heating component 22 to move closer to or away from the first heating component 21. In other words, the first movable component 23 is used to drive the second heating component 22 to move along the first direction X. The first direction X is the arrangement direction of the first heating component 21 to the second heating component 22. In some embodiments, the first direction X is a vertical direction.

[0070] During heating, the first moving component 23 can be used to drive the second heating component 22 to be pressed downward, so that the lower surface of the second heating component 22 contacts the upper surface of the core material 200, thereby improving the heating of the core material 200 and further improving the heating and degassing efficiency and effect of the core material 200.

[0071] The first movable component 23 can be a linear reciprocating motion structure, such as a cylinder, a hydraulic cylinder, an electric cylinder, a motor-driven dimensional rack, a motor-driven crank slider, etc. The first movable component 23 can also be a robotic arm, a robotic hand and other structures. This embodiment will not be described in detail, as long as it can drive the second heating component 22 to move along the first direction X.

[0072] The first heating component 21 and the second heating component 22 of this embodiment have various structural forms, for example, the first heating component 21 is an electric heating structure, and the second heating component 22 is other heating structures. Alternatively, the second heating component 22 is an electric heating structure, and the first heating component 21 is other heating structures. Alternatively, both the first heating component 21 and the second heating component 22 are electric heating structures.

[0073] Taking the example that both the first heating component 21 and the second heating component 22 are electric heating structures, the first heating component 21 of this embodiment may include a first heating plate 211 and a first heating wire 212 buried in the first heating plate 211, and the first heating plate 211 is provided with the above-mentioned first surface and second surface.

[0074] The first heating plate 211 is a plate structure with a shape matching that of the core material 200. The material of the first heating plate 211 is a material with certain heat conduction performance, such as rigid heat-conducting materials like metal, alumina, graphite, or ceramic. A plurality of channels (not labeled in the figure due to the obstruction of the first heating wire 212) are provided in the first heating plate 211. The plurality of channels can be connected in sequence or not connected. The shape of the first heating wire 212 is adapted to the shape of the channels. The first heating wire 212 is connected to a power source, which can be located inside or outside the vacuum chamber 10. The first heating wire 212 and the power source form a connection loop. After being energized, the first heating wire 212 generates heat and transfers the heat to the first heating plate 211, and the core material 200 is heated and degassed through the first heating plate 211.

[0075] Similarly, the second heating assembly 22 of this embodiment includes a second heating plate 221 and a second heating wire 222 embedded in the second heating plate 221. The material of the second heating plate 221 can be the same as that of the first heating plate 211. Channels are provided in the second heating plate 221, and the second heating wire 222 is installed in the channels.

[0076] Of course, the structural forms of the first heating assembly 21 and the second heating assembly 22 of this embodiment are not limited to this. Other structures capable of heating the core material 200 are also within the optional scope of this embodiment, such as the above-mentioned microwave, infrared heating, etc. This embodiment will not list them one by one.

[0077] Combined with the attached Figure 3 As shown in the figure, in some examples, optionally, the processing equipment 100 of this embodiment further includes a first temperature detection component 60 and a second temperature detection component 70. The first temperature detection component 60 of this embodiment is connected to the first heating plate 211 and is used to detect the temperature of the first heating plate 211.

[0078] The first temperature detection component 60 can be directly embedded in the first heating plate 211 or directly installed on the surface of the first heating plate 211, as long as it can detect the temperature of the first heating plate 211. This embodiment does not make too many limitations on this.

[0079] The second temperature detection component 70 of this embodiment is connected to the second heating plate 221 and is used to detect the temperature of the second heating plate 221. The second temperature detection component 70 can also be embedded in the second heating plate 221 or installed on the surface of the second heating plate 221.

[0080] The first temperature detection component 60 can be a structure capable of detecting temperature, such as a temperature sensor, an infrared thermometer, a thermometer, etc. Similarly, the second temperature detection component 70 of this embodiment can also be the above-mentioned temperature sensor.

[0081] In this embodiment, a temperature sensor capable of transmitting temperature detection signals to the outside is adopted. The temperature sensor can be a thermocouple temperature sensor, a thermistor temperature sensor, a semiconductor temperature sensor, an infrared temperature sensor, etc., and this embodiment will not list them one by one.

[0082] In some embodiments, the processing device 100 is provided with a control device (not shown in the figure). The control device may include structures such as a processor or a PLC control circuit. The control device is connected to the temperature sensor through a line or a communication signal, so as to obtain the temperature information of the first heating component 21 and the second heating component 22.

[0083] Moreover, the control device can also be connected with a display structure to display the temperature through the display structure, so that the operator can know whether the heating temperature meets the requirements.

[0084] In addition, the control device can also be connected to the first heating component 21 and the second heating component 22 through a line or a communication signal. For example, the control device can be connected to the power supplies of the first heating wire 212 and the second heating wire 222, and the heating temperatures of the first heating component 21 and the second heating component 22 are controlled by controlling the opening and closing of the power supplies and the output voltage, so that the heating temperatures of the first heating component 21 and the second heating component 22 reach the ideal heating temperature, thereby realizing the automation of temperature control.

[0085] In addition, a sixth moving component 24 can be installed at the bottom of the first heating component 21. The sixth moving component 24 is installed on the bottom wall of the vacuum chamber 10, and the first heating component 21 is driven to move up and down by the sixth moving component 24.

[0086] Again referring to the attached Figure 1 and the attached Figure 3 As shown, in some examples, optionally, the encapsulation device 30 includes a first hot pressing component 31, a second hot pressing component 32, and a second moving component 33.

[0087] The first hot pressing component 31 has a first hot pressing surface (the upper surface of the first hot pressing frame 311) for pressing the four peripheral edges of the protective film 300. In some embodiments, the protective film 300 may be composed of a first diaphragm 310 and a second diaphragm 320. The first diaphragm 310 is laid on the lower surface of the core material 200, and the second diaphragm 320 is laid on the upper surface of the core material 200. The sizes of the first diaphragm 310 and the second diaphragm 320 are both larger than the size of the core material 200, so that both the first diaphragm 310 and the second diaphragm 320 have edges located outside the core material 200.

[0088] When the encapsulation device 30 and the heating device 20 of this embodiment exist independently and are not in the same working station (such an implementation manner is not shown in the figure), the first hot pressing assembly 31 is used to press the lower surface of the first diaphragm 310, and the second hot pressing assembly 32 is used to press the lower surface of the second diaphragm 320, so that the whole of the first diaphragm 310 and the whole of the second diaphragm 320 are in close contact with the core material 200, and the edges of the first diaphragm 310 and the second diaphragm 320 are hot-pressed into one body.

[0089] When the encapsulation device 30 and the heating device 20 of this embodiment are in the same working station as shown in the figure, and the first hot pressing assembly 31 surrounds the first heating assembly 21 and the second hot pressing assembly 32 surrounds the second heating assembly 22, the first hot pressing assembly 31 can be used to press the lower surface of the edge of the first diaphragm 310, and the second hot pressing assembly 32 can be used to press the upper surface of the edge of the second diaphragm 320, so that the edges of the first diaphragm 310 and the second diaphragm 320 form an integral edge through hot pressing.

[0090] At this time, the first hot pressing assembly 31 has a first hot pressing surface for pressing the four peripheral edges of the protective film 300, the second hot pressing assembly 32 is arranged facing the first hot pressing surface and has a second hot pressing surface for pressing the four peripheral edges of the protective film 300, and the second moving assembly 33 is connected to the second hot pressing assembly 32 and is used to drive the second hot pressing assembly 32 to approach or move away from the first hot pressing assembly 31.

[0091] The second moving assembly 33 has the same or similar structure as the aforementioned first moving assembly 23. For example, the second moving assembly 33 can be a structure such as a cylinder, an electric cylinder, a hydraulic cylinder, a robotic arm, etc.

[0092] The second moving assembly 33 is used to drive the second hot pressing assembly 32 to approach or move away from the first hot pressing assembly 31. When encapsulating, the second moving assembly 33 drives the second hot pressing assembly 32 to press down, so that the first hot pressing assembly 31 and the second hot pressing assembly 32 press the first diaphragm 310 and the second diaphragm 320 therebetween, and the two are integrally heat-melted and connected.

[0093] In order to improve the hot pressing efficiency and effect, in some embodiments, the encapsulation device 30 further includes a third moving assembly 34. The third moving assembly 34 is connected to the first hot pressing assembly 31 and is used to drive the first hot pressing assembly 31 to approach or move away from the second hot pressing assembly 32.

[0094] In some embodiments, the third moving assembly 34 has the same or similar structure as the aforementioned first moving assembly 23 and the second moving assembly 33. Therefore, this embodiment does not describe the third moving assembly 34 in too much detail.

[0095] The third moving component 34 can drive the first hot pressing component 31 closer to the second hot pressing component 32, while the second moving component 33 drives the second hot pressing component 32 closer to the first hot pressing component 31, enabling the first hot pressing component 31 and the second hot pressing component 32 to perform hot pressing work faster. Moreover, the first hot pressing component 31 can also drive the edge of the first diaphragm 310 upward, such that the edges of the first diaphragm 310 and the second diaphragm 320 are at the middle position in the thickness direction of the core material 200. The hot-pressed edges at the middle position can provide a better encapsulation effect.

[0096] Based on the above structure, in this embodiment, the heating device 20 and the encapsulation device 30 are also structurally improved. The encapsulation device 30 and the heating device 20 are at the same working station, and encapsulation can be directly performed after heating and degassing the core material 200. Meanwhile, the heating device 20 can also function as a hot pressing and encapsulating device during the encapsulation process.

[0097] Combined with the attached Figures 1-3 As shown in the figure, in some examples, optionally, in this embodiment, the first hot pressing component 31 is arranged around the first heating component 21, and the first hot pressing component 31 is supported and fixed by the above-mentioned third moving component 34. And the second hot pressing component 32 is arranged around the second heating component 22, and the second hot pressing component 32 is supported and fixed by the above-mentioned second moving component 33.

[0098] On the above basis, the processing equipment 100 of this embodiment can also be designed to further include a fourth moving component 40 and a fifth moving component 50. Both the fourth moving component 40 and the fifth moving component 50 are installed in the vacuum chamber 10, and both the fourth moving component 40 and the fifth moving component 50 can be robotic arms controlled by the above-mentioned control device.

[0099] In some embodiments, the fourth moving component 40 can include a first robotic arm 41 and a second robotic arm 42, and both the first robotic arm 41 and the second robotic arm 42 have mechanical grippers for clamping the core material 200.

[0100] Similarly, the fifth moving component 50 can include a third robotic arm 51 and a fourth robotic arm 52, and both the third robotic arm 51 and the second robotic arm 42 have mechanical grippers for clamping the first diaphragm 310 or the second diaphragm 320.

[0101] The fourth moving component 40 and the fifth moving component 50 have at least three degrees of freedom, such as the first direction X and the second direction Y perpendicular to the first direction X in the figure, and the third direction Z perpendicular to the first direction X and the second direction Y respectively, in some embodiments.

[0102] The fourth moving component 40 is used to drive the core material 200 on the first heating component 21 to move along the first direction X, and the first direction X is the arrangement direction from the first heating component 21 to the second heating component 22, that is, the vertical direction in the figure.

[0103] After the core material 200 is heated and degassed, move the core material 200 along the first direction X so that a gap is formed between the lower surface of the core material 200 and the first surface of the first heating component 21, forming the state shown in the attached figure. Figure 4 The state shown in the attached figure.

[0104] The way to move the core material 200 can be to manually clamp the core material 200 with a clamping structure partially located in the vacuum chamber 10 to drive the core material 200 to move. During this process, the vacuum chamber 10 always maintains a vacuum state, or it can be to use the fourth moving component 40 of this embodiment to drive the core material 200 to move.

[0105] After moving the core material 200, place the first diaphragm 310 on the first surface and directly below the core material 200, and then place the core material 200 on the first diaphragm 310, forming the state shown in the attached figure. The first diaphragm 310 can be realized by a diaphragm feeder (not shown in the figure) located in the vacuum chamber 10, or the diaphragm can be pre-placed in the vacuum chamber 10 and then realized by the fifth moving component 50 of this embodiment. Figure 5 The state shown in the attached figure. The first diaphragm 310 can be realized by a diaphragm feeder (not shown in the figure) located in the vacuum chamber 10, or it can be to drive the first diaphragm 310 to move through the fifth moving component 50 of this embodiment.

[0106] Subsequently, place the second diaphragm 320 on the upper surface of the core material 200, forming the state shown in the attached figure. The second diaphragm 320 can be realized by a diaphragm feeding device (not shown in the figure) located in the vacuum chamber 10, or it can be to drive the second diaphragm 320 to move through the fifth moving component 50 of this embodiment. Figure 6 The state shown in the attached figure. The second diaphragm 320 can be realized by a diaphragm feeding device (not shown in the figure) located in the vacuum chamber 10, or it can be to drive the second diaphragm 320 to move through the fifth moving component 50 of this embodiment.

[0107] Then, drive the first hot pressing component 31 and the second hot pressing component 32 to perform the hot pressing and encapsulation operation of the diaphragm respectively through the second moving component 33 and the third moving component 34 of this embodiment, forming the state shown in the attached figure. Figure 7 The state shown in the attached figure.

[0108] At the same time, the first moving component 23 can also be used to drive the second heating component 22 of this embodiment to press down, so that the second heating component 22 and the first heating component 21 simultaneously press the first diaphragm 310 and the second diaphragm 320 against the upper and lower surfaces of the core material 200.

[0109] When the first heating component 21 and the second heating component 22 press down the first diaphragm 310 and the second diaphragm 320, the first heating component 21 and the second heating component 22 can be heated or not heated.

[0110] In the above process, the first heating component 21 and the second heating component 22 can not only heat and degas the core material 200, but also assist in pressing the package, serving multiple purposes in one body with a clever structure.

[0111] Combined with the attached Figure 2 and 3 shown, in some examples, optionally, the first hot pressing component 31 includes a first hot pressing frame 311, the first hot pressing frame 311 is arranged to surround the first heating component 21, and the third moving component 34 is connected to the first hot pressing frame 311.

[0112] The first hot pressing frame 311 can be a rectangular frame. Of course, the specific shape needs to be determined according to the shape of the first hot pressing plate and the shape of the core material 200.

[0113] There can be a gap or space between the side of the first hot pressing frame 311 and the first heating plate 211 to prevent wear or mutual interference when the first hot pressing frame 311 or the first hot pressing plate moves.

[0114] Similarly, the second hot pressing component 32 of this embodiment includes a second hot pressing frame 321 facing the first hot pressing frame 311. The second hot pressing frame 321 is arranged to surround the second heating component 22, and the second moving component 33 is connected to the second hot pressing frame 321.

[0115] The second hot pressing frame 321 is arranged around the second hot pressing plate and can have a gap or space with the second hot pressing plate to prevent wear or mutual interference when the second hot pressing frame 321 or the second hot pressing plate moves.

[0116] The materials of the first hot pressing frame 311 and the second hot pressing frame 321 can also be rigid heat-conducting materials such as metal, alumina, graphite or ceramic. The first hot pressing frame 311 can be filled with a third heating wire 312, and the second hot pressing frame 321 can be filled with a fourth heating wire 322. Both the third heating wire 312 and the fourth heating wire 322 are connected to a power supply. By the heat generated by the third heating wire 312 and the fourth heating wire 322, the first hot pressing frame 311 and the second hot pressing frame 321 are heated, so that the first hot pressing frame 311 and the second hot pressing frame 321 can hot press and bond the edges of the first diaphragm 310 and the second diaphragm 320.

[0117] Combined with the attached Figure 3 shown, in order to better achieve the hot pressing effect, the first hot pressing frame 311 and the second hot pressing frame 321 of this embodiment can also be designed as a split structure.

[0118] In some embodiments, the first hot pressing frame 311 includes a plurality of first border members 3111. The plurality of first border members 3111 are arranged along the circumferential direction of the first heating component 21. The number of the third moving components 34 is plural. The plurality of third moving components 34 are connected to the plurality of first border members 3111 in one-to-one correspondence. Each third moving component 34 is configured to drive the first border member 3111 connected thereto to approach or move away from the second hot pressing frame 321.

[0119] Taking the first hot pressing frame 311 in the figure as a rectangle, for example, there can be four first border members 3111. Correspondingly, the number of the third moving components 34 can also be four. The four third moving components 34 are connected to the four first border members 3111 in one-to-one correspondence.

[0120] Similarly, the second hot pressing frame 321 includes a plurality of second border members (not shown in the figure). The plurality of second border members are arranged along the circumferential direction of the second heating component 22. The number of the second moving components 33 matches the number of the second border members. Each second moving component 33 is configured to drive the second border member connected thereto to approach or move away from the first hot pressing frame 311.

[0121] Through such a structural design, the pressing down of a plurality of first border members 3111 or a plurality of second border members can be performed in sequence. Taking the first hot pressing frame 311 as an example, when one of the adjacent two first border members 3111 is pressed down while the other first border member 3111 is not, gas and other impurities remaining in the partially adjacent non-pressed portions of the first diaphragm 310 and the second diaphragm 320 that are being pressed can be discharged in time, providing better encapsulation control and achieving a better encapsulation effect.

[0122] Combined with the attached Figure 9 As shown, based on the above-mentioned processing equipment 100 for a vacuum insulation panel, an embodiment of the present application further provides a method for processing a vacuum insulation panel, applying the processing equipment 100 for a vacuum insulation panel of the above technical solution.

[0123] The method for processing a vacuum insulation panel in this embodiment includes the following steps:

[0124] Heating the core material 200 in the vacuum chamber 10 to discharge the gas inside the core material 200;

[0125] Encapsulating the protective film 300 for the core material 200 that has completed gas discharge in the same vacuum chamber 10.

[0126] This processing method integrates the heating and degassing of the core material 200 and the encapsulation in the vacuum environment of the vacuum chamber 10, without the need for transporting the core material 200. This not only improves the operation efficiency, but also avoids the core material 200 adsorbing gas and water due to being exposed to the air after heating and degassing, reducing the possibility of continuous outgassing of the core material 200 after encapsulation, enabling the internal pressure of the vacuum insulation panel to be in a low-pressure state for a long time, thereby improving the heat insulation performance of the encapsulated core material 200.

[0127] Among them, the heating and degassing of the core material 200 is carried out by the heating device 20 of this embodiment, and the specific structure and heating method of the heating device 20 have been given above.

[0128] The packaging of the protective film 300 for the core material 200 is carried out by the above-mentioned encapsulation device 30, and the heating device 20 can also be used for auxiliary encapsulation, which has been given above, and will not be elaborated in this embodiment.

[0129] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
