(Vacuum suction process). Next, as shown in FIG. 11, the film material 103 is heated by turning on the heater 107 while suctioning the interior of the upper and lower chambers to a vacuum state (film heating step). At this time, in order to prevent excessive dripping of the heat-softened film material 103, the gas stored in the gas supply chamber 109 is sent into the lower chamber 101b to adjust the pressure difference in the upper and lower chambers. Next, as shown in FIG. 12, the table 108 in the lower chamber 101b is raised to a predetermined position (table raising step). Next, as shown in FIG. 13, the film in the upper chamber 101a is released and the atmosphere is put in, so that the film material 103 is pressed against the base material 102 to be pasted (film pasting step).

JP 2002-67137 A

However, the film-coated component manufacturing apparatus and method described in Patent Document 1 have the following problems.
That is, in the fill pasting step shown in FIG. 13, when the upper chamber 101a is opened to atmospheric pressure or higher, the lower chamber b remains in a vacuum state. A load that pushes downward is exerted on. For this reason, the table driving device 101d having a push-up capability capable of withstanding the load is required.
In particular, with the recent increase in size and integration of vehicle parts, there is a high demand for handling large film-coated parts. Therefore, when the planar size of the table 108 is increased, an excessive pushing load proportional to the table area acts on the table 108, so the table driving device 101d must be a large-scale device having a large hydraulic cylinder or the like. There was a problem that equipment cost and installation space increased significantly.
In addition, when the push-up capability of the table driving device 101d is insufficient, the table 108 descends even when a pressure higher than the atmospheric pressure is applied to the film material 103 using the compressed air tank 106, etc. There was a problem that was likely to cause defects and equipment failures.

  The present invention has been made to solve the above-described problems, and is gripped between the upper chamber and the lower chamber on the surface of the substrate placed on the table raised to a predetermined position by the table driving device. In the manufacturing equipment and manufacturing method for film-covered parts in which the heated and softened film material is adhered by the pressure difference, the equipment cost and installation space based on the simplification of the table drive device can be reduced, and molding defects and equipment failures are avoided. The purpose is to be able to.

In order to solve the above problems, a film-coated component manufacturing apparatus and method according to the present invention have the following configuration.
(1) An upper chamber and a lower chamber that can be joined and separated in the vertical direction, a vacuum circuit and an air circuit connected to each chamber, a heater mounted in the upper chamber or the lower chamber, A table disposed in a lower chamber so as to be movable up and down, and a table driving device that raises and lowers the table, on the surface of the base material placed on the table raised to a predetermined position by the table driving device, An apparatus for manufacturing a film-covered component that adheres a film material that has been gripped between the upper chamber and the lower chamber and heat-softened by a pressure difference,
After raising the table to a predetermined position by the table driving device, the vacuum circuit of the lower chamber is stopped and simultaneously the air circuit of the lower chamber is operated, and then the vacuum circuit of the upper chamber is stopped. At the same time, a control unit for operating the air circuit of the upper chamber is provided.

In the present invention, after the table is raised to a predetermined position by the table driving device, the vacuum circuit of the lower chamber is stopped and at the same time the air circuit of the lower chamber is operated. The lower chamber can be opened to the atmosphere while the upper chamber is kept in a vacuum state. Therefore, in addition to the push-up force of the table driving device, a force that lifts upward based on the pressure difference acts on the table in the lower chamber. Therefore, when the film is stuck, the push-up capability of the table driving device can be reinforced by the atmospheric pressure in the lower chamber.
In addition, the control unit thereafter stops the vacuum circuit of the upper chamber and simultaneously operates the air circuit of the upper chamber, so that the lower chamber is brought to atmospheric pressure and the upper chamber is opened to the atmosphere. Can do. Therefore, when a film is stuck, for example, even if a pressure or higher pressure is applied to the film material using a compressed air tank or the like, the pressure difference in the upper and lower chambers is zero or minute, and the load presses the table downward. Is slight. Therefore, even if the push-up capability of the table driving device is small, the table does not easily descend, and it is possible to avoid the occurrence of molding defects and equipment failures.
As a result, it is possible to simplify the table driving device while avoiding the occurrence of molding defects and equipment failures.
Therefore, according to the present invention, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device, and to avoid molding defects and equipment failures.

(2) In the film coated component manufacturing apparatus described in (1),
The table includes an outer wall projecting upward so as to surround the base material, and the outer wall seals the outer wall and the lower chamber when the table is raised to a predetermined position. It is formed so that it may closely contact via a member.

In the present invention, the table includes an outer wall portion protruding upward so as to surround the base material, and the outer wall portion and the lower chamber are sealed when the table is raised to a predetermined position. Since the inside of the lower chamber is opened to the atmosphere, it is surrounded by the outer wall portion and held in a vacuum state between the film material and the table on which the base material is placed. Airtight space is formed. Therefore, after that, even if the pressure difference in the upper and lower chambers becomes zero or minute by releasing the atmosphere in the upper chamber to the atmosphere, the film material is made to be the base material by the pressure difference between the upper chamber and the airtight space. It can be applied by pressing on the surface.
In addition, since the outer wall portion and the lower chamber are formed in close contact with each other through the seal member when the table is raised to a predetermined position, the airtight space is formed in a state where the vacuum state sucked by the vacuum circuit of the lower chamber is airtight. It can be stored as it is in the space. Further, since the table is pushed upward by the atmospheric pressure in the lower chamber, even if the pushing capacity of the table driving device is small, the airtight space is less likely to cause air leakage, and the vacuum state can be maintained.
As a result, the equipment cost and installation space based on the simplification of the table driving device can be reduced, and molding defects and equipment failures can be further avoided.

(3) In the film-coated component manufacturing apparatus described in (2),
The lower chamber includes a second vacuum circuit communicating with the hermetic space, and the control unit operates the second vacuum circuit when a film is attached.

In the present invention, the lower chamber is provided with the second vacuum circuit communicating with the airtight space, and the control unit operates the second vacuum circuit when the film is stuck, so that the film-coated component having a large or complicated shape is formed. Even when the film is stuck, the vacuum state of the airtight space can be maintained or improved. Therefore, the film material can be pressed without excess or deficiency to a large-sized or complicated base material, and can be reliably adhered.
As a result, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device, and to further avoid molding defects and equipment failures for large or complicated film-coated parts.

The film sticking step is characterized in that the upper chamber is opened to the atmosphere after the lower chamber opening step to release the lower chamber to the atmosphere while keeping the upper chamber in a vacuum state.

In the present invention, since the upper chamber is opened to the atmosphere after the lower chamber atmosphere opening step in which the lower chamber is opened to the atmosphere while the upper chamber is kept in a vacuum state, the upper chamber is opened to the atmosphere before the film is stuck. The lower chamber can be opened to the atmosphere while the upper chamber is kept in a vacuum state. Therefore, in addition to the push-up force of the table driving device, a force that lifts upward based on the pressure difference acts on the table in the lower chamber. Therefore, when the film is stuck, the push-up capability of the table driving device can be reinforced by the atmospheric pressure in the lower chamber.
Also, in the film pasting process, the lower chamber is opened to the atmosphere and then the upper chamber is opened to the atmosphere. Therefore, when the film is stuck, for example, a pressure tank or the like is used to act on the film material at a pressure higher than atmospheric pressure. Even if it is made, the pressure difference in the upper and lower chambers is zero or minute, and the load for pressing the table downward is slight. Therefore, even if the push-up capability of the table driving device is small, the table does not easily descend, and it is possible to avoid the occurrence of molding defects and equipment failures.
As a result, it is possible to simplify the table driving device while avoiding the occurrence of molding defects and equipment failures.
Therefore, according to the present invention, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device, and to avoid molding defects and equipment failures.

(5) In the method for producing a film-coated component described in (4),
The table includes an outer wall portion projecting upward so as to surround the base material, and when the table is raised to a predetermined position, the outer wall portion and the lower chamber are closely contacted via a seal member. It is characterized by making it.

In the present invention, the table is provided with an outer wall portion protruding upward so as to surround the base material, and when the table is raised to a predetermined position, the outer wall portion and the lower chamber are in close contact with each other via the seal member. Therefore, after the inside of the lower chamber is opened to the atmosphere, an airtight space surrounded by the outer wall portion and maintained in a vacuum state is formed between the film material and the table on which the base material is placed. Therefore, after that, even if the pressure difference in the upper and lower chambers becomes zero or minute by releasing the atmosphere in the upper chamber to the atmosphere, the film material is made to be the base material by the pressure difference between the upper chamber and the airtight space. It can be applied by pressing on the surface.
In addition, since the outer wall portion and the lower chamber are formed in close contact with each other through the seal member when the table is raised to a predetermined position, the airtight space is formed in a state where the vacuum state sucked by the vacuum circuit of the lower chamber is airtight. It can be stored as it is in the space. Further, since the table is pushed upward by the atmospheric pressure in the lower chamber, even if the pushing capacity of the table driving device is small, the airtight space is less likely to cause air leakage, and the vacuum state can be maintained.
As a result, the equipment cost and installation space based on the simplification of the table driving device can be reduced, and molding defects and equipment failures can be further avoided.

(6) In the method for producing a film-coated component described in (5),
The lower chamber includes a second vacuum circuit communicating with the hermetic space, and the second vacuum circuit is operated in the film sticking step.

In the present invention, the lower chamber is provided with the second vacuum circuit communicating with the airtight space, and the second vacuum circuit is operated in the film sticking step. Even in the attaching step, the vacuum state of the airtight space can be maintained or improved. Therefore, the film material can be pressed without excess or deficiency to a large-sized or complicated base material, and can be reliably adhered.
As a result, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device, and to further avoid molding defects and equipment failures for large or complicated film-coated parts.

  According to the present invention, the film material gripped between the upper chamber and the lower chamber and softened by heating is pasted to the surface of the substrate placed on the table raised to a predetermined position by the table driving device due to the pressure difference. In the manufacturing apparatus and manufacturing method for the film-covered parts to be attached, the equipment cost and installation space based on the simplification of the table driving device can be reduced, and molding defects and equipment failures can be avoided.

Further, in the manufacturing apparatus 10, after the table 4 is raised to a predetermined position by the table driving device 5, the vacuum circuit 21 of the lower chamber 2 is stopped and the air circuit 22 of the lower chamber 2 is operated at the same time. In addition, a control unit 8 is provided for controlling the air circuit 12 of the upper chamber 1 to be activated simultaneously with stopping the vacuum circuit 11 of the upper chamber 1.

(Upper chamber)
The upper chamber 1 is a box-shaped molding chamber having an open bottom, and a vacuum circuit 11 is connected to the side wall, and an air circuit 12 is connected to the upper wall. The vacuum circuit 11 is communicated with a vacuum pump (not shown) through an open / close valve. When the vacuum circuit 11 is operated, the upper chamber 1 is sucked from the atmospheric pressure state to the vacuum state. The air circuit 12 is communicated with outside air through an opening / closing valve. When the air circuit 12 is operated, the inside of the upper chamber 1 is returned to the atmospheric pressure state. The air circuit 12 is communicated with a pressurized air tank (not shown) via a switching valve, and a gas at atmospheric pressure or higher can be sent into the upper chamber 1 as necessary. Further, a pressure adjustment valve 15 is attached to the side wall of the upper chamber 1 so that the atmospheric pressure in the upper chamber 1 can be adjusted.

The upper chamber 1 is equipped with an infrared heater (heater) 3 for heating and softening the film material F. A plurality of heaters 3 are arranged along the ceiling, and a radiation thermometer 14 for measuring the temperature of the film material F is arranged in the gap between the heaters 3. The heater 3 may be attached to both the upper chamber 1 and the lower chamber 2 or only to the lower chamber 2.
A film presser 13 that presses the edge of the film material F formed in a sheet shape in an airtight manner is formed at the lower end of the side wall of the upper chamber 1. The film presser 13 protrudes horizontally into and out of the side wall of the upper chamber 1. The lower surface (contact surface with the film material F) of the film pressing part 13 is formed in a flat surface.

(Lower chamber)
The lower chamber 2 is a box-shaped molding chamber whose upper side is open, and a vacuum circuit 21 and an air circuit 22 are connected to the side wall thereof. The vacuum circuit 21 is communicated with a vacuum pump (not shown) through an open / close valve. When the vacuum circuit 21 is operated, the lower chamber 1 is sucked from the atmospheric pressure state to the vacuum state. The air circuit 22 communicates with the outside air through an open / close valve. When the air circuit 22 is operated, the inside of the lower chamber 2 is returned to the atmospheric pressure state. A pressure regulating valve 24 is attached to the side wall of the lower chamber 2 so that the atmospheric pressure in the lower chamber 2 can be adjusted.
Further, a film receiving portion 23 is formed at the upper end of the side wall of the lower chamber 2 to receive the edge of the film material F formed in a sheet shape in an airtight manner. The film receiving portion 23 is formed in a size corresponding to the film pressing portion 13 of the upper chamber 1 and protrudes horizontally into and out of the side wall of the lower chamber 2. The upper surface of the film receiving portion 23 (the contact surface with the film material F) is formed as a flat surface. When the upper chamber 1 and the lower chamber 2 are joined, the film pressing portion 13 and the film receiving portion 23 are brought into close contact with each other to improve the airtightness in both the chambers.

(Table, table driving device)
The table 4 is a substantially rectangular plate-like table, and a base material receiving jig 44 on which the base material K is placed is formed at the center of the upper end. Further, the table 4 includes an outer wall portion 41 projecting upward so as to surround the base material K. When the table 4 is raised to a predetermined position, the upper surface of the outer wall portion 41 and the lower surface of the film receiving portion 23 of the lower chamber 2 are in close contact with each other via the seal member 42, and the film material F and the base material K are attached when the film is stuck. Is formed in an airtight space 6 surrounded by the outer wall portion 41 and kept in a vacuum state (see FIG. 4). Note that a sealing member 43 is also appropriately fitted to a fastening portion between the table 4 and the outer wall portion 41.
A table driving device 5 is connected to the center of the lower end of the table 4. The table driving device 5 is accommodated in the lower chamber 2. For the table driving device 5, for example, a scissor lifter can be used in order to reduce the size and simplify the table driving device 5.

<Method for producing film-coated component>
Next, the manufacturing method of the film covering component which is embodiment which concerns on this invention is demonstrated using FIGS. In FIG. 7, the follow chart figure in the manufacturing method of the film covering component which concerns on embodiment of this invention is shown.

  First, as shown in step S1 of FIG. 7, the upper chamber 1 and the lower chamber 2 are separated from each other by a predetermined distance, and the base material K and the film material F are set at predetermined positions in the chamber (see FIG. 1). . Step S1 corresponds to a setting process. Specifically, the table drive device 5 raises the table 4 to a predetermined position (a position where the upper surface of the outer wall portion 41 is in contact with the lower surface of the film receiving portion 23), and then the substrate K is received by the substrate receiving device. After placing on the jig 44, the table 4 is lowered to the original position, and the edge of the film material F is placed on the film receiving portion 23 and bonded. The base material K is made of a resin such as a polypropylene resin, an acrylic resin, a polystyrene resin, or an ABS resin, and is formed in a predetermined shape in advance. The film material F is, for example, a sheet-like decorative film material on which a wood grain pattern or the like is printed, and is made of a resin such as an acrylic resin, a polyester resin, or a polycarbonate resin. An adhesive is uniformly applied to the lower surface of the film material F.

  Next, as shown in step S2 of FIG. 7, the upper and lower chambers are joined in an airtight manner, and the film material F is heated while vacuuming the inside of the upper chamber 1 and the lower chamber 2 (see FIG. 2). reference). Step S2 corresponds to a vacuum suction process and a film heating process. Specifically, after the upper chamber 1 is lowered, the film receiving portion 23 and the film pressing portion 13 are brought into close contact with each other. As a result, the inside of the upper chamber 1 and the inside of the lower chamber 2 are sealed with the seal member F as a boundary. Next, the heater 3 is turned on, and the vacuum circuit 11 connected to the upper chamber 1 and the vacuum circuit 21 connected to the lower chamber 2 are respectively operated to suck the atmosphere in both chambers to obtain a vacuum state. The atmospheric pressure is reduced to (for example, about 100 to 50 Pa). While reaching the vacuum state, the film material F is heated and softened by turning on the heater 3. At this time, the air circuit 12 of the upper chamber 1 and the air circuit 22 of the lower chamber 2 are both stopped. In order to prevent the film material F from drooping excessively, the pressure adjustment valve 15 of the upper chamber 1 or the pressure adjustment valve 24 of the lower chamber 2 may be operated to adjust the pressure difference in the upper and lower chambers.

  Next, as shown in step S3 of FIG. 7, the table 4 is raised to a predetermined position (see FIG. 3). Step S3 corresponds to a table raising process. Specifically, the vacuum state in the upper chamber 1 and the lower chamber 2 and the heating temperature of the heater 3 with respect to the film material F are checked, and the table driving device 5 is activated when each reaches a predetermined value. Let At this stage, the vacuum circuits 11 and 21 in both chambers are in an activated state.

  Next, as shown in step S4 of FIG. 7, the lower chamber 2 is opened to the atmosphere (see FIG. 4). Step S4 is a lower chamber atmosphere release process newly added in the present embodiment. Specifically, the vacuum circuit 21 connected to the lower chamber 2 is stopped, and at the same time, the air circuit 22 of the lower chamber 2 is operated. At this stage, the vacuum circuit 11 of the upper chamber 1 is in an activated state. Therefore, only the lower chamber 2 is opened to the atmosphere while the upper chamber 1 is kept in a vacuum state. Therefore, in addition to the lifting force f2 of the table driving device 5, a force f1 that lifts upward based on the pressure difference acts on the table 4 in the lower chamber 2. At this time, the upper surface of the outer wall portion 41 formed on the table 4 and the lower surface of the film receiving portion 23 of the lower chamber 2 are in close contact with each other through the seal member 42, and the film material F and the substrate K are placed thereon. Between the table 4, an airtight space 6 surrounded by the outer wall portion 41 and kept in a vacuum state is formed.

  Next, as shown in step S5 of FIG. 7, the inside of the upper chamber 1 is opened to the atmosphere (see FIG. 5). Step S5 corresponds to a film sticking process. Specifically, the vacuum circuit 11 connected to the upper chamber 1 is stopped, and at the same time, the air circuit 12 of the upper chamber 1 is operated. By opening the inside of the upper chamber 1 to the atmosphere, a pressure difference is generated between the upper chamber 1 and the airtight space 6. The film material F is pressed against the surface of the substrate K by the pressing force f3 based on this atmospheric pressure difference. Note that a gas having an atmospheric pressure or higher can be sent into the upper chamber 1. Even in this case, since the table 4 is pressed upward by the atmospheric pressure in the lower chamber 2, the table 4 is not easily lowered, and the sealing performance in the airtight space 6 can be maintained.

  Next, as shown in step S6 of FIG. 7, when the film material F is attached to the base material K, the product of the film-covered component W is taken out (see FIG. 6). Step S6 corresponds to a product removal process. Specifically, the heater 3 is turned off, the upper chamber 1 is raised to a predetermined height, the outer peripheral edge of the film material F is cut, and the product of the film-covered component W is taken out of the upper and lower chambers. As described above in detail, the film-coated component W according to the present embodiment can be manufactured through the above steps S1 to S6.

  In addition, it cannot be overemphasized that this embodiment can be changed in the range which does not change the summary of this invention. For example, as shown in FIG. 8, the film covering component manufacturing apparatus 10 </ b> B is formed so that the outer wall portion 41 and the film receiving portion 23 are in close contact with each other via the seal member 42 when the table 4 is raised to a predetermined position. In addition, the film receiving portion 23 of the lower chamber 2 includes a second vacuum circuit 61 that communicates with the airtight space 6, and the control unit 8 may operate the second vacuum circuit 61 when the film is attached. Good.

<Effect>
As described above in detail, according to the film-coated component W manufacturing apparatus 10 according to the present embodiment, the table 4 is raised to a predetermined position by the table driving device 5 and then connected to the lower chamber 2. Since the control unit 8 that operates the air circuit 22 of the lower chamber 2 at the same time as stopping 21 is provided, the lower chamber 2 is opened to the atmosphere while the upper chamber 1 is kept in a vacuum state before the film is attached. Can do. Therefore, in addition to the push-up force f2 of the table drive device 5, a force f1 that lifts upward based on the pressure difference acts on the table 4 in the lower chamber 2. Therefore, the push-up capability of the table driving device 5 can be reinforced by the atmospheric pressure in the lower chamber 2 when the film is stuck.
Further, since the control unit 8 subsequently stops the vacuum circuit 11 connected to the upper chamber 1 and simultaneously operates the air circuit 12 of the upper chamber 1, the inside of the lower chamber 2 is brought into an atmospheric pressure state. The inside of the upper chamber 1 can be opened to the atmosphere. Therefore, when the film is attached, for example, even if a pressure higher than atmospheric pressure is applied to the film material F using a pressure tank or the like, the pressure difference in the upper and lower chambers is zero or minute, and the table 4 is pressed downward. The load to be applied is slight. Therefore, even if the push-up capability of the table driving device 5 is small, the table 4 cannot be easily lowered, and the occurrence of molding defects and equipment failures can be avoided.
As a result, it is possible to simplify the table driving device 5 while avoiding the occurrence of molding defects and equipment failures.
Therefore, according to this embodiment, the equipment cost and installation space based on simplification of the table drive device 5 can be reduced, and molding defects and equipment failures can be avoided.

Further, according to the present embodiment, the table 4 includes the outer wall portion 41 protruding upward so as to surround the base material K, and the outer wall portion 41 is raised when the table 4 is raised to a predetermined position. Since the outer wall portion 41 and the film receiving portion 23 of the lower chamber 2 are formed so as to be in close contact with each other via the seal member 42, the film material F and the substrate K are mounted after the lower chamber 2 is opened to the atmosphere. Between the placed table 4, an airtight space 6 surrounded by the outer wall portion 41 and kept in a vacuum state is formed. Therefore, after that, even if the pressure difference in the upper and lower chambers becomes zero or minute by releasing the atmosphere in the upper chamber 1, the film material is caused by the pressure difference between the inside of the upper chamber 1 and the airtight space 6. F can be pressed against the surface of the substrate K to be stuck.
Further, the airtight space 6 is formed so that the outer wall portion 41 and the film receiving portion 23 of the lower chamber 2 are in close contact with each other via the seal member 42 when the table 4 is raised to a predetermined position. The vacuum state sucked by the vacuum circuit 21 connected to can be stored in the airtight space 6 as it is. Further, since the table 4 is pushed upward by the atmospheric pressure in the lower chamber 2, even if the pushing capacity of the table driving device 5 is small, the airtight space 6 is less likely to cause air leakage and maintains its vacuum state. be able to.
As a result, the equipment cost and installation space based on the simplification of the table driving device 5 can be reduced, and molding defects and equipment failures can be further avoided.

Further, according to the present embodiment, the film receiving portion 23 of the lower chamber 2 includes the second vacuum circuit 61 that communicates with the airtight space 6, and the control unit 8 is configured to apply the second vacuum circuit 61 when the film is attached. Therefore, the vacuum state of the hermetic space can be maintained or improved even when the film covering part having a large or complicated shape is applied. Therefore, the film material can be pressed without excess or deficiency to a large-sized or complicated base material, and can be reliably adhered.
As a result, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device, and to further avoid molding defects and equipment failures for large or complicated film-coated parts.

Further, according to the method for manufacturing a film-coated component according to another embodiment, the film sticking step S5 is a lower chamber atmosphere release step S4 in which the lower chamber 2 is opened to the atmosphere while the upper chamber 1 is kept in a vacuum state. Thereafter, the upper chamber 1 is opened to the atmosphere, so that the lower chamber 2 can be opened to the atmosphere while the upper chamber 1 is kept in a vacuum state before the film is attached. Therefore, in addition to the push-up force f2 of the table drive device 5, a force f1 that lifts upward based on the pressure difference acts on the table 4 in the lower chamber 2. Therefore, the push-up capability of the table driving device 5 can be reinforced by the atmospheric pressure in the lower chamber 2 when the film is stuck.
Further, since the upper chamber 1 is opened to the atmosphere after the lower chamber 2 is opened to the atmosphere in the film pasting step S5, when the film is pasted, for example, a pressure higher than the atmospheric pressure is used by using a compressed air tank or the like. Even if it acts on the material F, the pressure difference in the upper and lower chambers is zero or minute, and the load that presses the table 4 downward is slight. Therefore, even if the push-up capability of the table driving device 5 is small, the table 4 does not easily descend, and it is possible to avoid the occurrence of molding defects and equipment failures.
As a result, it is possible to simplify the table driving device 5 while avoiding the occurrence of molding defects and equipment failures.
Therefore, according to this other embodiment, the equipment cost and installation space based on the simplification of the table driving device 5 can be reduced, and molding defects and equipment failures can be avoided.

According to this other embodiment, the table 4 includes the outer wall portion 41 projecting upward so as to surround the base material K, and when the table 4 is raised to a predetermined position, Since the film receiving portion 23 of the chamber 2 is brought into close contact with the sealing member 42 via the seal member 42, the outer wall portion 41 is placed between the film material F and the table 4 on which the substrate K is placed after the lower chamber 2 is opened to the atmosphere. A hermetic space 6 surrounded by and maintained in a vacuum state is formed. Therefore, after that, even if the pressure difference in the upper and lower chambers becomes zero or minute by releasing the atmosphere in the upper chamber 1, the film material is caused by the pressure difference between the inside of the upper chamber 1 and the airtight space 6. F can be pressed against the surface of the substrate K to be stuck.
The airtight space 6 is connected to the lower chamber 2 because the outer wall portion 41 and the film receiving portion 23 are in close contact with each other via the seal member 42 when the table 4 is raised to a predetermined position. The vacuum state sucked by the vacuum circuit 21 can be stored in the airtight space 6 as it is. Further, since the table 4 is pushed upward by the atmospheric pressure in the lower chamber 2, even if the pushing capacity of the table driving device 5 is small, the airtight space 6 is less likely to cause air leakage and maintains its vacuum state. be able to.
As a result, the equipment cost and installation space based on the simplification of the table driving device 5 can be reduced, and molding defects and equipment failures can be further avoided.

In addition, according to the other embodiment, the film receiving portion 23 of the lower chamber 2 includes the second vacuum circuit 61 communicating with the airtight space 6, and the second vacuum circuit 61 is provided in the film pasting step S5. Therefore, the vacuum state of the airtight space 6 can be maintained or improved even in the film sticking step S5 of the film-coated component W having a large or complicated shape. Therefore, the film material F can be pressed without excess or deficiency against the large-sized or complicated base material K, and can be reliably adhered.
As a result, it is possible to reduce the equipment cost and installation space based on the simplification of the table driving device 5 for the large-size or complicated-shaped film-coated component W, and to further avoid molding defects and equipment failures.
