Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic production equipment, and particularly relates to a laminator and a laminating method of the laminator. BACKGROUND

[0002] The laminator is used for laminating laminated pieces to form laminated pieces required by photovoltaic modules. The laminator in the prior art has the technical problem of large energy consumption in the laminating process. SUMMARY

[0003] Therefore, the present application provides a laminator and a laminating method of the laminator to solve the technical problem of large energy consumption of the laminator in the prior art.

[0004] In a first aspect, the present application provides a laminator, which comprises a carrier table, a pressing piece, a first air pump, a second air pump and a gas storage piece. The pressing piece comprises an elastic plate, the pressing piece is provided with a first cavity, the first cavity is located on the side of the elastic plate away from the carrier table, and the pressing piece can further form a second cavity together with the carrier table. The gas storage piece can be communicated with the first cavity through the first air pump, and the gas storage piece can be communicated with the second cavity through the second air pump.

[0005] The second air pump of the present application can extract the heated gas in the second chamber and fill the gas into the gas storage member, so that the heat of the heated gas is stored in the gas storage member. Since the first air pump also extracts the gas from the gas storage member, at least part of the gas with heat is filled into the first chamber by the first air pump. Accordingly, the pressure of the gas in the first chamber is relatively high, which further enables the elastic plate to reliably press the laminated member to the object table. In addition, under the condition that the heat and the pressure of the gas provided to the first chamber are relatively high, the amount of the gas provided to the first chamber can be relatively small, i.e. the working energy consumption of the first air pump is low. Further, since the gas with heat is filled into the first chamber, the ambient temperature in the second chamber is less affected, and the ambient temperature in the second chamber is less likely to decrease, and the energy consumption of the heating member is also low. The first air pump of the present application can extract at least part of the heated gas in the first chamber and fill the gas into the gas storage member, so that the heat of the heated gas is stored in the gas storage member. Since the second air pump also extracts the gas from the gas storage member, at least part of the gas with heat is filled into the second chamber by the second air pump. Accordingly, the pressure of the gas in the second chamber is relatively high, which enables the elastic plate to quickly deform in the direction away from the laminated member. In addition, under the condition that the heat and the pressure of the gas provided to the second chamber are relatively high, the amount of the gas provided to the second chamber can be relatively small, i.e. the working energy consumption of the second air pump is low. After the pressing member moves in the direction away from the object table, the second air pump can still extract at least part of the heated gas between the object table and the pressing member and fill the gas into the gas storage member, so that the energy of the heated gas is stored in the gas storage member, so as to reuse the gas with heat in the next laminating and heating process of the laminated member, so as to reduce the working energy consumption of the first air pump and the second air pump. In summary, the laminating machine of the present application can recycle the heat of the heated gas in the first chamber and the second chamber, so as to reduce the working energy consumption of the first air pump, the second air pump and the heating member.

[0047] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0050] A first aspect of this application provides a laminator that can be used to laminate and heat a stacked component to form a laminate. The laminate may include a front encapsulation layer (e.g., glass), an encapsulating film, solar cells, and a back encapsulation layer (e.g., glass or backsheet). The laminate is used to assemble with a frame assembly to form a photovoltaic module. Please refer to... Figure 1 As shown, the laminator 10 provided in this embodiment includes a stage 1, a pressing member 2, a first air pump 4a, a second air pump 4b, and an air storage member 5. The pressing member 2 includes an elastic plate 21 and is provided with a first chamber 3a, which is located on the side of the elastic plate 21 opposite to the stage 1. The pressing member 2 can also be combined with the stage 1 to form a second chamber 3b. The air storage member 5 can communicate with the first chamber 3a through the first air pump 4a, and can also communicate with the second chamber 3b through the second air pump 4b.

[0051] Please refer to Figure 1 As shown, stage 1 is used to place the laminated parts that have not been laminated and heated (not shown in the figure), and pressing element 2 is used to continuously press the laminated parts onto stage 1 for a user-set time. The laminator 10 may include a heating element (not shown in the figure) for heating the laminated parts to melt the adhesive film inside the laminated parts. After the adhesive film cools, the laminated parts are formed.

[0052] Please refer to Figure 1After the stack (not shown) is placed on the stage 1, the pressing member 2 can be moved to a set position (for example, a position where the pressing member 2 abuts against the stage 1) in the height direction (a direction parallel to the direction Y). Before starting to laminate the stack, a heating member (not shown) can first heat the stack to melt the adhesive film in the stack. At the same time, at least part of the gas in the first chamber 3a is extracted by the first gas pump 4a, and at least part of the gas in the second chamber 3b is extracted by the second gas pump 4b, so that the difference between the pressure of the gas in the first chamber 3a and the pressure of the gas in the second chamber 3b is small, and the elastic plate 21 is in a flat state, or the elastic plate 21 does not exert force on the stack, so that the adhesive film in the stack is heated and melted by the heating member without the pressure of the elastic plate 21, the amount of the adhesive film overflowing from the stack to the outside is reduced, the adhesive film of the laminated product has higher adhesive force and better puncture resistance, and the yield of the laminated product is improved. Wherein, Figure 1 The hollow triangle arrow represents the direction of gas flow.

[0053] Please refer to Figure 2As shown, after the laminated object is heated for a set time, the first air pump 4a can extract the gas from the gas storage 5 and fill the gas into the first chamber 3a provided in the pressing member 2. As the pressure of the gas in the first chamber 3a increases, the pressure of the gas in the first chamber 3a causes the elastic plate 21 to deform towards the object table 1 (in the direction opposite to the direction Y), and in the process, the elastic plate 21 presses the laminated object to the object table 1. Meanwhile, the pressing member 2 and the object table 1 can enclose the second chamber 3b, and the laminated object is located in the second chamber 3b. During the heating process, the pressure of the gas in the second chamber 3b gradually increases, and the direction of the pressure of the gas in the second chamber 3b is opposite to the direction of the pressure of the gas in the first chamber 3a, which can cause the pressure applied by the elastic plate 21 to the laminated object to decrease. Therefore, the second air pump 4b can extract at least part of the gas in the second chamber 3b to reduce the pressure of the gas in the second chamber 3b, so that the pressure applied by the elastic plate 21 to the laminated object can reliably be within the range of the value set by the user, i.e. the laminated object can be reliably laminated by the elastic plate 21, and the yield of the laminated object produced is high. Meanwhile, since the gas extracted from the second chamber 3b has been heated by the heating member, the second air pump 4b can fill the gas extracted from the second chamber 3b into the gas storage 5 to store the heat of the heated gas in the gas storage 5. Since the first air pump 4a also extracts the gas from the gas storage 5, at least part of the gas with heat is filled into the first chamber 3a by the first air pump 4a. Accordingly, the pressure of the gas in the first chamber 3a is relatively high, which further causes the elastic plate 21 to reliably press the laminated object to the object table 1. Secondly, under the condition that the heat and the pressure of the gas provided to the first chamber 3a are relatively high, the amount of the gas provided to the first chamber 3a can be relatively small, i.e. the energy consumption of the first air pump 4a is low. Further, since the gas with heat is filled into the first chamber 3a, the ambient temperature in the second chamber 3b is less likely to decrease, and the energy consumption of the heating member is also low. Among them, Figure 2 The hollow triangle arrow represents the direction of gas flow.

[0054] Please refer to Figure 3As shown, after the laminator 10 laminates and heats the stack according to the time set by the user, the first air pump 4a can pump at least part of the gas in the first chamber 3a into the gas storage 5 to reduce the pressure of the gas in the first chamber 3a, while the second air pump 4b pumps at least part of the gas in the gas storage 5 into the second chamber 3b to increase the pressure of the gas in the second chamber 3b. In this setting, the elastic plate 21 deforms in the direction away from the stack (direction Y), i.e. the pressure applied by the elastic plate 21 to the stack is weakened, or the elastic plate 21 does not apply pressure to the stack. Since the gas in the first chamber 3a has been indirectly heated by the heating element during the process of laminating and heating the stack, the first air pump 4a pumps at least part of the heated gas in the first chamber 3a into the gas storage 5 to store the heat of the heated gas in the gas storage 5. Since the second air pump 4b also pumps the gas from the gas storage 5, at least part of the gas with heat is pumped by the second air pump 4b into the second chamber 3b. Accordingly, the pressure of the gas in the second chamber 3b is relatively high, which can make the elastic plate 21 quickly deform in the direction away from the stack (direction Y). Secondly, under the condition of the heat of the gas provided to the second chamber 3b and the relatively high pressure, the amount of gas provided to the second chamber 3b can be relatively small, i.e. the energy consumption of the second air pump 4b is low. Wherein, Figure 3 The hollow triangle arrow represents the direction of gas flow.

[0055] Please refer to Figure 4 As shown, after the elastic plate 21 deforms in the direction away from the stack (direction Y), the first air pump 4a stops pumping the gas from the first chamber 3a, and the second air pump 4b stops pumping the gas into the second chamber 3b. Then, the pressing element 2 moves in the direction away from the object table 1 (direction Y) so that the stack is taken out. Although the object table 1 does not form the second chamber 3b with the pressing element 2, the second air pump 4b can still pump at least part of the heated gas between the object table 1 and the pressing element 2 into the gas storage 5 to store the energy of the heated gas in the gas storage 5, so that the gas with heat can be reused in the next process of laminating and heating the stack to reduce the energy consumption of the first air pump 4a and the second air pump 4b. Wherein, Figure 4 The hollow triangle arrow represents the direction of gas flow.

[0056] In summary, the laminator 10 of the embodiments of the present application can recycle the heat of the gas heated by the heating element in the first chamber 3a and the second chamber 3b to reduce the energy consumption of the first air pump 4a, the second air pump 4b and the heating element.

[0057] Wherein, the heating element can be integrally arranged in the interior of the object table 1.

[0058] In addition, the laminator 10 can further comprise a plurality of pipes 8, the air storage member 5 can be connected with the first air pump 4a through the pipes 8, the first air pump 4a can be connected with the pressing member 2 through the pipes 8, and the air storage member 5 can also be connected with the second air pump 4b through the pipes 8.

[0059] Furthermore, the laminator 10 can further comprise a plurality of valves 7, the pipes 8 connected with the air storage member 5 and the first air pump 4a are provided with the valves 7, so as to control the pipes 8 connected with the air storage member 5 and the first air pump 4a to be in a communication state or a disconnected state; the pipes 8 connected with the air storage member 5 and the second air pump 4b are also provided with the valves 7, so as to control the pipes 8 connected with the air storage member 5 and the second air pump 4b to be in a communication state or a disconnected state.

[0060] Optionally, the material of the elastic plate 21 comprises silica gel, so that the elastic plate 21 can be elastically deformed. The elastic plate 21 can comprise at least two connected plate layers (not shown in the figure), the plate layer facing the object table 1 has a smaller rigidity than the plate layer facing the first chamber 3a. When the plate layer facing the object table 1 presses the laminated piece, the laminated piece is not prone to structural problems such as breaking or cracking inside, and the yield rate of the laminated piece produced is higher.

[0061] Optionally, please refer to Figure 5 As shown in the figure, the laminator 10 further comprises a cover 6, and the cover 6 is provided with a third chamber 61. The second air pump 4b can communicate with the second chamber 3b through the third chamber 61.

[0062] Please refer to Figures 1-2 As shown in the figure, when the pressing member 2 abuts against the object table 1, there is a gap (not shown in the figure due to the relatively small size) between the pressing member 2 and the object table 1, and the second chamber 3b enclosed by the pressing member 2 and the object table 1 can communicate with the outside of the laminator 10 through the gap, and the cover 6 can cover at least part of the gap, so that the second air pump 4b can communicate with the second chamber 3b through the third chamber 61 and the gap, so as to effectively extract the gas with heat from the second chamber 3b by the second air pump 4b.

[0063] In which, the second air pump 4b is connected with the cover 6 through the pipes 8, and the pipes 8 connected with the second air pump 4b and the cover 6 are provided with the valves 7, so as to control the pipes 8 connected with the second air pump 4b and the cover 6 to be in a communication state or a disconnected state.

[0064] In other embodiments (not shown in the figure), a plurality of pipes 8 in parallel can be arranged around the object table 1, so that the second air pump 4b can communicate with the second chamber 3b through the plurality of pipes 8 in parallel.

[0065] Hereinafter, the subsequent contents are mainly described by taking the cover 6 as an example.

[0066] Optionally, the cover 6 is flexible. During the process of extracting the gas from the second chamber 3b, the cover 6 can be deformed flexibly due to the pressure of the gas inside the cover 6 or in the third chamber 61 being smaller than the pressure of the gas outside the cover 6, so as to relieve the stress concentration degree of the structure of the cover 6 and reduce the possibility of the structure of the cover 6 being damaged by the pressure of the gas due to the pressure difference. Therefore, the working reliability degree of the cover 6 with flexibility is higher.

[0067] The material of the cover 6 can include silica gel, so that the cover 6 is flexible.

[0068] In addition, the laminating machine 10 can further include a heat insulation layer (not shown in the figure) arranged on the inner side wall and / or the outer side wall of the cover 6, so that the heat loss of the gas with heat during the process of passing through the cover 6 is smaller. The material of the heat insulation layer can be foamed cotton or aluminum foil.

[0069] Optionally, referring to Figures 5-6 The cover 6 is provided with a first opening 611 and a second opening 612, the third chamber 61 can communicate with the second chamber 3b through the first opening 611, and the third chamber 61 can communicate with the second gas pump 4b through the second opening 612; the area of the first opening 611 is larger than the area of the second opening 612.

[0070] Referring to Figure 4 When the pressing piece 2 moves in the direction (direction Y) away from the object table 1 by a set distance, the spacing between the pressing piece 2 and the object table 1 becomes larger. Since the cover 6 has the first opening 611 with a relatively large area, the cover 6 can still cover at least part of the spacing between the pressing piece 2 and the object table 1, so that the spacing between the pressing piece 2 and the object table 1 can still communicate through the first opening 611, the third chamber 61, the second opening 612 and the second gas pump 4b, so as to facilitate the second gas pump 4b to effectively extract the gas with heat from the spacing between the pressing piece 2 and the object table 1. The second opening 612 with a relatively small area is arranged to facilitate the structure of the cover 6 for enclosing the second opening 612 to be connected with the second gas pump 4b or to facilitate the structure of the cover 6 for enclosing the second opening 612 to communicate with the pipe 8.

[0071] Optionally, a part of the end face of the cover 6, in which the first opening 611 is formed, is arranged on the side wall of the object table 1. In this arrangement, the possibility of the gas in the second chamber 3b leaking to the outside of the cover 6 through the cover 6 and the object table 1 is reduced, and the amount of the gas outside the cover 6 being sucked into the cover 6 through the cover 6 and the object table 1 is reduced, thereby reducing the possibility of the heat of the extracted gas being reduced. Another part of the end face of the cover 6, in which the first opening 611 is formed, is arranged on the side wall of the pressing member 2. In this arrangement, the possibility of the gas in the second chamber 3b leaking to the outside of the cover 6 through the cover 6 and the pressing member 2 is reduced, and the amount of the gas outside the cover 6 being sucked into the cover 6 through the cover 6 and the pressing member 2 is reduced, thereby reducing the possibility of the heat of the extracted gas being reduced.

[0072] Optionally, the laminating machine 10 further comprises a sealing member (not shown in the figure). The end face of the cover 6, in which the first opening 611 is formed, abuts against the side wall of the object table 1 and the side wall of the pressing member 2 through the sealing member. In this arrangement, the possibility of the gas in the second chamber 3b leaking to the outside of the cover 6 through the cover 6 and the object table 1 is further reduced, and the possibility of the gas in the second chamber 3b leaking to the outside of the cover 6 through the cover 6 and the pressing member 2 is further reduced, and the amount of the gas outside the cover 6 being sucked into the cover 6 is further reduced, thereby further reducing the possibility of the heat of the extracted gas being reduced.

[0073] The sealing member can be made of silica gel, rubber or felt. The sealing member can be ring-shaped. The sealing member can be attached to or embedded in the end face of the cover 6, in which the first opening 611 is formed.

[0074] Optionally, the laminating machine 10 comprises at least two covers 6 arranged opposite to each other with respect to the pressing member 2 in a direction (a direction parallel to the direction X) perpendicular to the moving direction (the direction Y) of the pressing member 2. In this arrangement, the efficiency of extracting the gas with heat from the second chamber 3b is higher, and the loss efficiency of the gas with heat in the second chamber 3b is lower, i.e., the heat recovery efficiency is higher.

[0075] Optionally, referring to Figure 1 The object table 1 is provided with a communication hole 11. One end of the communication hole 11 can communicate with the second chamber 3b, and the other end of the communication hole 11 can communicate with the gas storage member 5 through the second gas pump 4b.

[0076] Optionally, referring to Figure 1As shown, the second air pump 4b can extract the gas from the gas storage member 5 and drive the gas to be filled into the second chamber 3b rapidly via the communication hole 11, so as to make the elastic plate 21 bend and deform along the direction away from the laminated member (direction Y) rapidly and increase the pressure of the gas in the second chamber 3b rapidly, so as to separate the pressing member 2 from the object table 1. At least part of the gas in the second chamber 3b can be extracted by the second air pump 4b via the communication hole 11 and then filled into the gas storage member 5, so as to store at least part of the heat of the gas in the second chamber 3b in the gas storage member 5. Alternatively, at least part of the gas in the space between the pressing member 2 and the object table 1 can be extracted by the second air pump 4b via the communication hole 11 and then filled into the gas storage member 5, so as to store at least part of the heat of the gas in the space between the pressing member 2 and the object table 1 in the gas storage member 5.

[0077] In the embodiments of the present application, the number, size and shape of the communication hole 11 are not limited.

[0078] In addition, the second air pump 4b is connected to the object table 1 through the pipe member 8, so that the second air pump 4b is communicated with the communication hole 11 through the pipe member 8. The pipe member 8 connected to the second air pump 4b and the object table 1 is provided with a valve 7, so as to control the pipe member 8 connected to the second air pump 4b and the object table 1 to be in a communication state or a disconnected state.

[0079] Furthermore, at least part of the pipe member 8 connected to the second air pump 4b and the object table 1 is connected in parallel with at least part of the pipe member 8 connected to the second air pump 4b and the cover 6, so that the second air pump 4b can simultaneously generate negative pressure on the communication hole 11 provided on the object table 1 and the third chamber 61 provided on the cover 6, so as to simultaneously extract at least part of the gas in the second chamber 3b, which has a higher air extraction efficiency and a higher heat recovery efficiency.

[0080] Optionally, please refer to Figure 1 As shown, the pressing member 2 further comprises a cover 22, the elastic plate 21 is connected to the cover 22, and the cover 22 and the elastic plate 21 form the first chamber 3a. The elastic plate 21, the cover 22 and the object table 1 can form the second chamber 3b.

[0081] Please refer to Figure 1 As shown, under the action of external force, the cover 22 can drive the elastic plate 21 to move along the direction parallel to the direction Y, so that the cover 22 can be located at the position abutting against the object table 1 or at the position separated from the object table 1. When the cover 22 abuts against the object table 1, the elastic plate 21, the cover 22 and the object table 1 form the second chamber 3b. When the cover 22 is separated from the object table 1, the space between the elastic plate 21 and the object table 1 becomes larger, which is convenient for placing the laminated member on the object table 1 or taking out the laminated member.

[0082] The cover 22 has a box structure or a case structure, and the structural rigidity of the cover 22 is greater than that of the elastic plate 21, so that the cover 22 is not easily deformed. The cover 22 is provided with a third opening 221, and the first chamber 3a can communicate with the first air pump 4a through the third opening 221.

[0083] In addition, the laminating machine 10 can further include a driving member (not shown in the figure) capable of driving the cover 22 to move in a direction parallel to the direction Y.

[0084] Further, the first air pump 4a is connected to the cover 22 through the pipe 8, so that the first air pump 4a communicates with the third opening 221 through the pipe 8. The pipe 8 connected to the cover 22 and the first air pump 4a is provided with the valve 7, so as to control the pipe 8 connected to the cover 22 and the first air pump 4a to be in a communication state or a disconnected state.

[0085] The direction Y in the figure is perpendicular to the direction X, and the direction Y is parallel to the height direction of the laminating machine 10.

[0086] The second aspect of the present application provides a laminating method of a laminating machine. The laminating machine 10 described above is used to laminate the laminated pieces to form a laminated piece. Please refer to Figure 7 The method can include: extracting at least part of the gas located between the pressing member 2 and the worktable 1 and filling the extracted gas into the gas storage member 5. The method of the present application can recycle the heated gas located between the pressing member 2 and the worktable 1, so that the heat of the heated gas is stored in the gas storage member 5. In this way, the laminating machine 10 can reuse the recycled heat, thereby reducing the working energy consumption of the laminating machine 10. In addition, the method of the present application can also be used to adjust the pressure of the gas located between the pressing member 2 and the worktable 1.

[0087] Specifically, when the laminating machine 10 is in the state as shown in Figures 1-2 , the pressing member 2 and the worktable 1 enclose the second chamber 3b. The heating member heats the laminated pieces, and at the same time, the gas in the second chamber 3b is heated. The second air pump 4b can extract at least part of the gas located in the second chamber 3b and fill the extracted gas into the gas storage member 5, so that the heat of the heated gas is stored in the gas storage member 5. Figure 4 When the laminating machine 10 is in the state as shown in , the pressing member 2 and the worktable 1 are separated. The second air pump 4b can extract at least part of the gas located in the space between the pressing member 2 and the worktable 1 and fill the extracted gas into the gas storage member 5, so that the heat of the heated gas is stored in the gas storage member 5.

[0088] The method provided by the embodiment of the present application can also include: extracting at least part of the gas in the first chamber 3a and filling the extracted gas from the first chamber 3a into the gas storage member 5. The method of the embodiment of the present application can recycle the heated gas in the first chamber 3a, so that the heat of the heated gas is stored in the gas storage member 5, so that the laminating machine 10 can reuse the recycled heat, thereby reducing the working energy consumption of the laminating machine 10.

[0089] Specifically, when the laminating machine 10 is in the state as shown in Figure 1 or as shown in Figure 3 , the first gas pump 4a can extract the heated gas in the first chamber 3a and fill the extracted gas into the gas storage member 5, so that the heat of the heated gas is stored in the gas storage member 5.

[0090] Optionally, as shown in Figure 2 , the method of the embodiment of the present application further includes: extracting at least part of the gas in the gas storage member 5 and filling the extracted gas from the gas storage member 5 into the first chamber 3a. Since the gas storage member 5 stores the gas with heat, at least part of the gas with heat is filled into the first chamber 3a by the first gas pump 4a. Accordingly, the pressure of the gas in the first chamber 3a is relatively high, which further enables the elastic plate 21 to reliably press the laminated member to the object table 1. Secondly, under the condition that the heat and the pressure of the gas provided to the first chamber 3a are relatively high, the amount of the gas provided to the first chamber 3a can be relatively small, that is, the working energy consumption of the first gas pump 4a is relatively low. Further, since the gas with heat is filled into the first chamber 3a, the environment temperature in the second chamber 3b is less affected, the environment temperature in the second chamber 3b is not easily reduced, and the energy consumption of the heating member is also relatively low.

[0091] Optionally, as shown in Figure 3 , the method of the embodiment of the present application further includes: extracting at least part of the gas in the gas storage member 5 and filling the extracted gas from the gas storage member 5 into the second chamber 3b, so as to increase the pressure of the gas in the second chamber 3b, the elastic plate 21 will be deformed in the direction (direction Y) away from the laminated member, and the subsequent separation of the pressing member 2 and the object table 1 is facilitated. Since the gas storage member 5 stores the gas with heat, at least part of the gas with heat is filled into the second chamber 3b by the second gas pump 4b. Accordingly, the pressure of the gas in the second chamber 3b is relatively high, which enables the elastic plate 21 to quickly deform in the direction (direction Y) away from the laminated member. Secondly, under the condition that the heat and the pressure of the gas provided to the second chamber 3b are relatively high, the amount of the gas provided to the second chamber 3b can be relatively small, that is, the working energy consumption of the second gas pump 4b is relatively low.

[0092] Optionally, as shown in Figure 8As shown, the specific flow of the laminating method of the laminating machine provided by the embodiments of the present application can be as follows:

[0093] Step S1: at least part of the gas in the first chamber 3a and at least part of the gas in the second chamber 3b are extracted, and the gas extracted from the first chamber 3a and the gas extracted from the second chamber 3b are filled into the gas storage member 5.

[0094] Step S2: at least part of the gas in the second chamber 3b is extracted, and the gas extracted from the second chamber 3b is filled into the gas storage member 5; at least part of the gas in the gas storage member 5 is extracted, and the gas extracted from the gas storage member 5 is filled into the first chamber 3a.

[0095] Step S3: at least part of the gas in the first chamber 3a is extracted, and the gas extracted from the first chamber 3a is filled into the gas storage member 5; at least part of the gas in the gas storage member 5 is extracted, and the gas extracted from the gas storage member 5 is filled into the second chamber 3b.

[0096] Step S4: the extraction of the gas in the first chamber 3a is stopped, the pressing member 2 is moved away from the object table 1, at least part of the gas between the pressing member 2 and the object table 1 is extracted, and the gas extracted from the pressing member 2 and the object table 1 is filled into the gas storage member 5.
