Description

Technical Field

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

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

[0003] Based on the vacuum insulation principle, 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 order to keep the inside of the vacuum insulation panel in a low-pressure state for a long time, it is necessary to heat and degas the core material of the vacuum insulation panel before encapsulating the core material, and add an adsorbent. The adsorbent needs to be pre-heated and activated before being installed on the core material, and then the activated adsorbent is vacuum encapsulated. Finally, the encapsulated adsorbent is broken and installed on the core material. However, in related technologies, the encapsulation and breaking of the adsorbent require certain costs and time, and it is easy to have poor sealing of the adsorbent encapsulation, resulting in the adsorbent absorbing air and moisture when transferred to the core material, thereby reducing the production yield of the adsorbent.

[0048] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0049] 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. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0050] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0051] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inner", "outer", "inside", "outside", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure is flipped, an element described as "below" or "beneath" other elements or features will then be oriented as "above" or "over" other elements or features. Thus, the example term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are accordingly interpreted.

[0052] 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 generally consists of a core material, a film material, an adsorbent, and an adsorbent. 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, and an adsorbent is placed after heating and baking.

[0053] In the related art, the heating and baking of the core material and the packaging of the adsorbent are separated. Generally, the core material is heated at one station, the adsorbent is heated at another station, and then the adsorbent is vacuum-packed. The vacuum-packed adsorbent is transferred to the station of the core material, and the vacuum package needs to be broken to place the adsorbent inside the package on the surface or inside the core material.

[0054] The above combination process of the core material and the adsorbent has many problems. First, the process flow is complex. It not only requires heating and activating the adsorbent, but also requires vacuum packaging and breaking the shell after packaging, resulting in low production efficiency. Second, the vacuum packaging of the adsorbent has strict requirements for equipment, and the cost of the equipment is high. Third, the problem of leakage of the vacuum packaging seal of the adsorbent often occurs easily, resulting in the adsorbent after packaging absorbing air and moisture during the transfer to the core material, reducing the product yield of the adsorbent.

[0055] 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 the heating and baking for degassing and the activation of the adsorbent in a vacuum chamber, the activated adsorbent is directly placed on the core material, omitting the processes of packaging, breaking the shell, and transferring the adsorbent to solve the above technical problems.

[0056] The following combines the appendix Figures 1 - 10An introduction is made to the processing equipment of the vacuum insulation panel of the present application.

[0057] Combined with the attached Figure 1 As shown, an embodiment of the present application provides a processing equipment 100 for a vacuum insulation panel, including a vacuum chamber 10, a heating device 20, an activation device 40, and a first transfer device 50. The heating device 20 is installed in the vacuum chamber 10 and is used to heat the core material 200; the activation device 40 is located in the vacuum chamber 10 and is used to heat and degas and activate the adsorbent 400; the first transfer device 50 is installed in the vacuum chamber 10 and is used to transfer the adsorbent 400 on the activation device 40 to the core material 200 of the heating device 20.

[0058] Among them, 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 so that the box forms 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 after evacuating the space is much lower than the atmospheric pressure, but there are not completely no gas molecules.

[0059] 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.

[0060] The heating device 20 of this embodiment is installed in the vacuum chamber 10. The heating device 20 is used to heat the core material 200, so as to degas 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 packaging.

[0061] The activation device 40 of this embodiment is located inside the vacuum chamber 10 and is used to heat and degas the adsorbent 400 and activate it. Heating and degassing and activation can remove the gas and impurities in the adsorbent 400, expose the active sites on the surface of the adsorbent 400, thereby improving the adsorption capacity of the adsorbent 400, better adsorbing the outgassing after the core material 200 is packaged, and further improving the heat insulation performance of the vacuum insulation panel.

[0062] The first transfer device 50 of this embodiment can be installed on the side, top or bottom of the vacuum chamber 10. The first transfer device 50 can be connected to the activation device 40, or the first transfer device 50 only generates a connection relationship (such as clamping connection) with the activation device 40 when transferring the activation device 40. Through the first transfer device 50, the heated and activated adsorbent 400 can be transferred to the core material 200 that has been heated and degassed on the heating device 20. Specifically, the adsorbent 400 can be placed on the surface or inside the core material 200.

[0063] When processing the vacuum insulation panel with the processing equipment 100 of this embodiment, the core material 200 can be heated and degassed by the heating device 20 first, and at the same time or subsequently, the adsorbent 400 can be heated, degassed and activated. Then, the cooled adsorbent 400 is placed on the surface or inside the heated and degassed core material 200 through the first transfer device 50 to perform the encapsulation of the core material 200 and the adsorbent 400. The whole process does not require processes such as encapsulating the adsorbent 400 and breaking the shell after encapsulation. The adsorbent 400 will not have the problem of decreased adsorption capacity due to poor sealing inside the vacuum chamber 10, thereby improving the product yield of the adsorbent 400, and saving the cost and time of assembling the adsorbent 400 and the core material 200, achieving the effect of cost reduction and efficiency improvement.

[0064] Combined with the attached Figure 2 and 3 As shown, in some examples, optionally, the activation device 40 includes a receiving member 41 and a first heating member 42 connected to the receiving member 41. The receiving member 41 refers to a structure for receiving the adsorbent 400, and the first heating member 42 is used to heat the receiving member 41, thereby heating the adsorbent 400 inside the receiving member 41.

[0065] The material of the receiving member 41 can be a material with certain heat conduction ability, such as metal, alumina, graphite, etc., and this embodiment does not list them one by one.

[0066] When the first heating element 42 heats the receiving element 41, the receiving element 41 transfers heat to the adsorbent 400 inside it, thereby achieving the heating and activation of the adsorbent 400. By heating and activating the adsorbent 400 in the receiving element 41 with the first heating element 42, the structure is simple and easy to implement.

[0067] The receiving element 41 is provided with at least one opening 411. The opening 411 can facilitate the entry or exit of the adsorbent 400 from the receiving element 41. The size of the opening 411 is not limited as long as it can satisfy the insertion of the adsorbent 400 and the pouring of the adsorbent 400. In some embodiments, the size of the opening 411 can allow the mechanical claw of the robotic arm to extend in to pick up and place the adsorbent 400.

[0068] The receiving element 41 can be a rectangular box structure. In some examples, optionally, the receiving element 41 includes a bottom wall 412 and side walls 413 connected to the four sides of the bottom wall 412. The bottom wall 412 and the side walls 413 can be formed into an integral structure by mechanical connection methods such as welding, heat fusion connection, and bonding, or the bottom wall 412 and the side walls 413 can be directly integrally formed by a mold during processing.

[0069] The bottom wall 412 and the side walls 413 enclose a receiving groove with an opening 411. When the receiving element 41 is in a heating state, the opening 411 of the receiving groove faces upward. The opening 411 at the top can reduce the possibility of the adsorbent 400 detaching from the receiving element 41 during heating.

[0070] The number of the first heating elements 42 can be one or more. The heating method of the first heating element 42 can be electric heating, infrared heating, microwave heating, etc. In this embodiment, an example is described with the first heating element 42 including a first heating wire 421 with an electric heating method. When the first heating element 42 includes the first heating wire 421, it can be connected to an external power supply (not shown in the figure) through a circuit or directly installed with a power supply inside the receiving element 41.

[0071] The first heating element 42 is connected to the bottom wall 412 and / or the side walls 413, that is, the first heating element 42 can be connected to the bottom wall 412, or the first heating element 42 can be connected to the side walls 413, or the first heating element 42 is respectively connected to the bottom wall 412 and the side walls 413. The connection method can be installed on the inner wall surface or the outer wall surface of the bottom wall 412 or the side walls 413, or a sandwich layer 4121 is provided on the bottom wall 412 and / or the side walls 413, and the first heating element 42 is installed in the sandwich layer 4121.

[0072] Such as Figure 3As shown, a sandwich layer 4121 can be provided on the bottom wall 412. The first heating element 42 includes a first heating wire 421 installed in the sandwich layer 4121. Both the bottom wall 412 and the side wall 413 are made of the above-mentioned heat-conducting material. The heat of the first heating wire 421 can be transferred to the adsorbent 400 in the accommodating member 41 through the bottom wall 412 and the side wall 413.

[0073] Compared with the form of setting the first heating wire 421 on the outer surface of the bottom wall 412 or the side wall 413, providing a sandwich layer 4121 on the bottom wall 412 and / or the side wall 413 to install the first heating wire 421 can reduce the overall volume of the accommodating member 41 and facilitate the first heating element 42 to heat the side wall 413 or the bottom wall 412.

[0074] Of course, it can also be that the first heating wire 421 is placed in a heating plate, and the heating plate is installed on the bottom wall 412 or the side wall 413 (this implementation is not shown in the figure).

[0075] In some examples, optionally, the processing device 100 further includes a first temperature detection member 43. The first temperature detection member 43 is connected to the accommodating member 41 and is used to detect the temperature of the accommodating member 41.

[0076] In some embodiments, the first temperature detection member 43 can be located in the accommodating groove surrounded by the accommodating member 41, or can also be located in the sandwich layer 4121 of the bottom wall 412 as shown in Figure 3 the figure.

[0077] The first temperature detection member 43 can be a structure capable of detecting temperature such as a temperature sensor, an infrared thermometer, a thermometer, etc. Similarly, the following second temperature detection member 25 and third temperature detection member 26 in this embodiment can also be the above-mentioned temperature sensors.

[0078] In this embodiment, a temperature sensor capable of transmitting a temperature detection signal 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 does not list them one by one.

[0079] In some embodiments, the processing device 100 is provided with a control device (not shown in the figure). The control device can 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 accommodating member 41.

[0080] Moreover, the control device can also be connected to a display structure to display the temperature through the display structure, so that the operator can know whether the heating temperature of the accommodating member 41 meets the requirements for activating the adsorbent 400, and it is convenient to control the heating activation temperature.

[0081] Combined with the attachedFigure 1 and the attached Figure 4 As shown, in some examples, optionally, the first transfer device 50 includes a first robotic arm 51 for driving the activation device 40 to move and rotate.

[0082] The first robotic arm 51 can simulate the movement of a human arm and has characteristics such as multiple degrees of freedom, precise positioning, and flexible operation. For example, the first robotic arm 51 in this embodiment has three degrees of freedom along the first direction X, the second direction Y, and the third direction Z that are pairwise perpendicular in the figure. The first direction X can be the thickness direction of the core material 200, the second direction Y is the length of the core material 200, and the third direction Z is the width direction of the core material 200. Of course, the first robotic arm 51 can also have other degrees of freedom of movement.

[0083] The first robotic arm 51 can perform actions such as picking up, moving, and rotating the receiving member 41, and can also directly grab the adsorbent 400 in the receiving member 41 and place it into the core material 200. The first robotic arm 51 can be controlled by the above control device or other control systems, thereby achieving the automation and intelligence of the assembly of the adsorbent 400 and the core material 200.

[0084] In some examples, optionally, the first robotic arm 51 is provided with a first jaw 511 configured to be able to perform actions of grasping and releasing the activation device 40. The jaw can not only be used to grasp and drive the activation device 40 to move, but also release the grasping of the activation device 40 to perform other auxiliary work.

[0085] Combined with the attached Figures 5 - 9 As shown, in some examples, optionally, the heating device 20 includes a second heating element 21 and a third heating element 22. The second heating element 21 includes opposite first surface 2111 and second surface 2112. The first surface 2111 is for placing the core material 200 and heating the core material 200. The third heating element 22 is disposed facing the first surface 2111 and forms a gap greater than or equal to the thickness of the core material 200 with the first surface 2111.

[0086] In some embodiments, the first surface 2111 of this embodiment can be the upper surface of the second heating element 21, and the second surface 2112 can be the lower surface of the second heating element 21. The second surface 2112 can be directly connected to the bottom of the vacuum chamber 10 or indirectly connected through an intermediate structure.

[0087] The heating methods of the second heating element 21 and the third heating element 22 can also be electric heating, infrared heating, microwave heating, etc. As long as the heating method can be carried out in a vacuum environment, it is within the optional scope of this embodiment.

[0088] In some embodiments, the third heating element 22 may be located directly above the second heating element 21. The side of the third heating element 22 facing the first surface 2111 has a third surface 2211 (the lower surface in the figure), and an interval greater than or equal to the thickness of the core material 200 is formed between the third surface 2211 and the first surface 2111.

[0089] The third surface 2211 can heat the core material 200 located between the second heating element 21 and the third heating element 22. Specifically, the third heating element 22 can directly heat the upper surface of the core material 200, and the second heating element 21 can directly heat the lower surface of the core material 200. Heat can be transferred to the inside of the core material 200, thereby achieving a degassing effect.

[0090] The heating device 20 configured with both the second heating element 21 and the third heating element 22 has better heating efficiency and heating effect, thereby improving the degassing effect of the core material 200.

[0091] To further improve the heating effect of the third heating element 22, in some examples, optionally, the heating device 20 further includes a first moving component 23. The first moving component 23 of this embodiment can be installed on the top or side plate of the vacuum chamber 10. The first moving component 23 is connected to the third heating element 22 and is used to drive the third heating element 22 to approach or move away from the second heating element 21. Or rather, the first moving component 23 is used to drive the third heating element 22 to move along the first direction X. The first direction X is the arrangement direction from the second heating element 21 to the third heating element 22. In some embodiments, the first direction X is the vertical direction.

[0092] During heating, the first moving component 23 can be used to drive the third heating element 22 to press down, so that the lower surface of the third heating element 22 is in contact with the upper surface of the core material 200, thereby heating the core material 200 better and further improving the heating and degassing efficiency and effect of the core material 200.

[0093] The first moving component 23 can be a linear reciprocating motion structure, such as a cylinder, a hydraulic cylinder, an electric cylinder, a rack and pinion driven by a motor, a crank-slider driven by a motor, etc. The first moving component 23 can also be a robotic arm, a manipulator, etc. Structures. This embodiment will not describe too much about this, as long as it can drive the third heating element 22 to move along the first direction X.

[0094] There are various structural forms of the second heating element 21 and the third heating element 22 in this embodiment. For example, the second heating element 21 is an electric heating structure, and the third heating element 22 is other heating structures. Or the third heating element 22 is an electric heating structure, and the second heating element 21 is other heating structures. Or both the second heating element 21 and the third heating element 22 are electric heating structures.

[0095] Taking the case where both the second heating element 21 and the third heating element 22 are electric heating structures, the second heating element 21 of this embodiment may include a first heating plate 211 and a second heating wire 212 embedded in the first heating plate 211. The first heating plate 211 is provided with the above-mentioned first surface 2111 and second surface 2112.

[0096] The first heating plate 211 is a plate structure whose shape matches the shape 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 ceramics. A plurality of channels (not marked in the figure due to the occlusion of the second heating wire 212) are provided in the first heating plate 211. The plurality of channels may be connected in sequence or not connected. The shape of the second heating wire 212 is adapted to the shape of the channels. The second heating wire 212 is also connected to a power source (not shown in the figure). The power source may be located inside or outside the vacuum chamber 10. The second heating wire 212 forms a connection circuit with the power source. After being energized, the second 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.

[0097] Similarly, the third heating element 22 of this embodiment includes a second heating plate 221 and a third heating wire 222 embedded in the second heating plate 221. The material of the second heating plate 221 may be the same as that of the first heating plate 211. Channels are provided in the second heating plate 221, and the third heating wire 222 is installed in the channels.

[0098] Of course, the structural forms of the second heating element 21 and the third heating element 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 and infrared heating, etc. This embodiment will not list them one by one.

[0099] Using the first moving assembly 23 can not only drive the third heating element 22 to move, facilitating the second heating element 21 to be close to the core material 200, but also enable the second heating element 21 and the third heating element 22 to form an operating interval, facilitating the first robotic arm 51 of this embodiment to place the adsorbent 400 into the core material 200.

[0100] Of course, the heating device 20 of this embodiment can also be designed to further include a second moving assembly 24. The second moving assembly 24 is installed below the second heating element 21 and is used to drive the second heating element 21 to move up and down to further improve the efficiency of the second heating element 21 and the third heating element 22 approaching or moving away from each other.

[0101] In some examples, optionally, the processing device 100 further includes a second temperature detector 25 and a third temperature detector 26. The second temperature detector 25 is connected to the second heating element 21 and is used to detect the temperature of the second heating element 21. The third temperature detector 26 is connected to the third heating element 22 and is used to detect the temperature of the third heating element 22.

[0102] The second temperature detector 25 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 excessive limitations in this regard.

[0103] In this embodiment, the third temperature detector 26 is connected to the second heating plate 221 and is used to detect the temperature of the second heating plate 221. The third temperature detector 26 can also be embedded in the second heating plate 221 or installed on the surface of the second heating plate 221.

[0104] Both the second temperature detector 25 and the third temperature detector 26 can be connected to the above-mentioned control device. By using the third temperature detector 26 to detect the temperature of the third heating element 22, it is convenient for the control device to control the temperatures of the second heating element 21 and the third heating element 22.

[0105] In addition, in the related art, after heating and baking for degassing, the core material 200 with the adsorbent 400 is usually transferred to a vacuum packaging device for packaging. During this process, the exposure time of the core material 200 and the adsorbent 400 in the air usually exceeds 5 minutes, resulting in a large amount of gas and water in the air being adsorbed by the core material 200 and the adsorbent 400, greatly reducing the previous degassing effect and the subsequent adsorption performance of the adsorbent 400. Moreover, this will cause the core material 200 to continuously release gas after encapsulation. Since the previous adsorption performance of the adsorbent 400 has decreased, it cannot well adsorb the gas released by the core material 200, resulting in an increase in the internal pressure of the vacuum insulation panel and a decrease in the insulation performance. Therefore, this embodiment further improves the processing device 100.

[0106] Combined with the attached Figure 1 、attached Figures 5 - 10 As shown, in some examples, optionally, the processing device 100 further includes a packaging device 30. The packaging device 30 is installed in the vacuum chamber 10 and is used to package the core material 200 and the adsorbent 400 with the packaging film 300.

[0107] The encapsulation device 30 of this embodiment is used to wrap the encapsulation film 300 around 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, thus ensuring its heat insulation performance. The encapsulation 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 body, 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.

[0108] After the heating device 20 heats the core material 200, and when 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 manually or mechanically for encapsulation operations. When the heating device 20 and the encapsulation device 30 are integrated as shown in the attached drawings of this embodiment, heating and encapsulation can be directly carried out at the same station.

[0109] The encapsulation film 300 is located inside the vacuum chamber 10. Therefore, a storage device or a feeding device for the encapsulation film 300 (not shown in the figure) can be configured in the vacuum chamber 10.

[0110] An encapsulation device 30 is provided inside the vacuum chamber 10, integrating the heating and baking degassing of the core material 200 and the adsorbent 400 with vacuum packaging in a single vacuum chamber 10, reducing the exposure time of the core material 200 and the adsorbent 400 to air, 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 panels, and at the same time improving production efficiency.

[0111] In some examples, optionally, the encapsulation device 30 includes a first hot pressing component 31, a second hot pressing component 32, a third moving component 33, and a fourth moving component 34. The first hot pressing component 31 and the second hot pressing component 32 are oppositely arranged along the first direction X. The third moving component 33 is used to drive the first hot pressing component 31 to move along the first direction X, and the fourth moving component 34 is used to drive the second hot pressing component 32 to move along the first direction X. The first direction X is the moving direction from the second heating element 21 to the third heating element 22, and it is also the thickness direction of the core material 200.

[0112] The first hot pressing assembly 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 encapsulation film 300. In some embodiments, the encapsulation 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.

[0113] When the encapsulation device 30 and the heating device 20 in this embodiment exist independently and are not in the same working station (this 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 closely attached to the core material 200, and the edges of the first diaphragm 310 and the second diaphragm 320 are hot pressed into one body.

[0114] When the encapsulation device 30 and the heating device 20 in this embodiment are in the same working station as shown in the figure, and the first hot pressing assembly 31 surrounds the second heating element 21, and the second hot pressing assembly 32 surrounds the third heating element 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.

[0115] At this time, the first hot pressing assembly 31 has a first hot pressing surface for pressing the four peripheral edges of the encapsulation 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 encapsulation film 300. The third moving assembly 33 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. The fourth moving assembly 34 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.

[0116] The third moving assembly 33 and the fourth moving assembly 34 have the same or similar structures as the aforementioned first moving assembly 23. For example, both the third moving assembly 33 and the fourth moving assembly 34 can be structures such as cylinders, electric cylinders, hydraulic cylinders, robotic arms, etc.

[0117] During encapsulation, the fourth moving component 34 drives the second hot pressing component 32 to press downwards, and the third moving component 33 drives the first hot pressing component 31 to press upwards. The first hot pressing component 31 and the second hot pressing component 32 clamp the first diaphragm 310 and the second diaphragm 320 therebetween, and make the edges after the thermocompression bonding of the first diaphragm 310 and the second diaphragm 320 be at the middle position in the thickness direction of the core material 200. The thermocompressed edges at the middle position can provide a better encapsulation effect.

[0118] 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 located at the same station, so that after the core material 200 is heated and degassed, encapsulation can be directly carried out. At the same time, the heating device 20 can also play the role of thermocompression encapsulation during the encapsulation process.

[0119] 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 second heating element 21, and the first hot pressing component 31 is supported and fixed by the above-mentioned third moving component 33. And the second hot pressing component 32 is arranged around the third heating element 22, and the second hot pressing component 32 is supported and fixed by the above-mentioned fourth moving component 34.

[0120] Specifically, the first hot pressing component 31 includes a first hot pressing frame 311. The first hot pressing frame 311 surrounds the second heating element 21, and the third moving component 33 is connected to the first hot pressing frame 311. The second hot pressing component 32 includes a second hot pressing frame 321 facing the first hot pressing frame 311. The second hot pressing frame 321 surrounds the third heating element 22, and the fourth moving component 34 is connected to the second hot pressing frame 321.

[0121] 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.

[0122] There can be a gap or an interval between the side of the first hot pressing frame 311 and the first heating plate 211 to prevent wear or mutual interference between the two when the first hot pressing frame 311 or the first hot pressing plate moves.

[0123] There can be a gap or an interval between the first hot pressing frame 311 and the first hot pressing plate to prevent wear or mutual interference between the two when the first hot pressing frame 311 or the first hot pressing plate moves. Similarly, there can be a gap or an interval between the second hot pressing frame 321 and the second hot pressing plate to prevent wear or mutual interference between the two when the second hot pressing frame 321 or the second hot pressing plate moves.

[0124] 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, aluminum oxide, graphite or ceramic. The first hot pressing frame 311 can be filled with a fourth heating wire 312, and the second hot pressing frame 321 can be filled with a fifth heating wire 322. Both the fourth heating wire 312 and the fifth heating wire 322 are connected to a power source. The first hot pressing frame 311 and the second hot pressing frame 321 are heated by the heat generated by the fourth heating wire 312 and the fifth heating wire 322, so that the first hot pressing frame 311 and the second hot pressing frame 321 can hot press and combine the edges of the first diaphragm 310 and the second diaphragm 320.

[0125] In addition, 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.

[0126] Combined with the attached Figure 10 As shown, in some embodiments, the first hot pressing frame 311 includes a plurality of first frame members 3111. The plurality of first frame members 3111 are arranged along the circumference of the second heating member 21. The number of the third moving components 33 is multiple. The multiple third moving components 33 are connected to the plurality of first frame members 3111 in one-to-one correspondence. Each third moving component 33 is used to drive the first frame member 3111 connected thereto to approach or move away from the second hot pressing frame 321.

[0127] Taking the rectangular first hot pressing frame 311 as an example, it can have four first frame members 3111. Correspondingly, the number of the third moving components 33 can also be four. The four third moving components 33 are connected to the four first frame members 3111 in one-to-one correspondence.

[0128] Similarly, the second hot pressing frame 321 includes a plurality of second frame members (not shown in the figure). The plurality of second frame members are arranged along the circumference of the third heating member 22. The number of the fourth moving components 34 matches the number of the second frame members. Each fourth moving component 34 is used to drive the second frame member connected thereto to approach or move away from the first hot pressing frame 311.

[0129] Through this structural design, the pressing down of multiple first frame members 3111 or multiple second frame members can be carried out in sequence. Taking the first hot pressing frame 311 as an example, when one of the adjacent two first frame members 3111 is pressed down and the other first frame member 3111 is not pressed down, the gas and other impurities remaining in the adjacent non-pressed parts of the first diaphragm 310 and the second diaphragm 320 that are pressed can be discharged in time, providing better encapsulation control and achieving a better encapsulation effect.

[0130] In addition, combined with the attached Figure 1 and the attached Figure 5 and the attached Figure 9As shown, the processing equipment 100 of the embodiment of the present application further includes a second transfer device 60, and the second transfer device 60 has the same or similar structure as the aforementioned first transfer device 50. For example, the second transfer device 60 may include a second robotic arm 61.

[0131] When encapsulating the core material 200 and the adsorbent 400, one of the first transfer device 50 and the second transfer device 60 is used to drive the core material 200 to be separated from the second heating element 21 and form a gap with the first surface 2111 of the second heating element 21, forming an attached Figure 5 state.

[0132] Then the other of the first transfer device 50 and the second transfer device 60 places the first diaphragm 310 between the core material 200 and the second heating element 21, forming an attached Figure 6 state.

[0133] Then the core material 200 is lowered so that the lower surface of the core material 200 presses against the upper surface of the first diaphragm 310, and the second diaphragm 320 is placed on the upper surface of the core material 200 by one of the first transfer device 50 and the second transfer device 60, forming an attached Figure 7 state.

[0134] Finally, the first diaphragm 310 and the second diaphragm 320 are encapsulated on the core material 200 by the first hot pressing assembly 31 and the second hot pressing assembly 32 of this embodiment. During the encapsulation process, the second heating element 21 and the third heating element 22 can also be used to press the first diaphragm 310 and the second diaphragm 320 tightly, forming an attached Figure 8 and 9 state.

[0135] When the second heating element 21 and the third heating element 22 press the first diaphragm 310 and the second diaphragm 320, the second heating element 21 and the third heating element 22 can be heated or not heated.

[0136] The second heating element 21 and the third heating element 22 in the above process can not only heat and degas the core material 200, but also assist in pressing the encapsulation, serving multiple purposes in one body with a clever structure.

[0137] Combined with the attached Figure 11 shown, based on the above-mentioned processing equipment 100 for vacuum insulation panels, the embodiment of the present application provides a processing method for vacuum insulation panels, including the following steps:

[0138] Heating and degassing the core material 200 in the vacuum chamber 10;

[0139] Heating and degassing and activating the adsorbent 400 in the vacuum chamber 10, and transferring the heated, degassed, and activated adsorbent 400 to the core material 200 after heating and degassing;

[0140] The encapsulation of the core material 200 and the adsorbent 400 is also carried out in the vacuum chamber 10 of this embodiment.

[0141] Among them, the heating and degassing of the core material 200 are realized by the above-mentioned heating device 20 of this embodiment. The heating and degassing and activation of the adsorbent 400 are realized by the above-mentioned activation device 40 and the first transfer device 50. The encapsulation of the core material 200 and the adsorbent 400 is realized by the above-mentioned encapsulation device 30, the first transfer device 50 and the second transfer device 60. Since the functions and working processes of each device have been given above, they will not be elaborated in this embodiment.

[0142] As mentioned above, it 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 within 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.
