Fig. 1 is a perspective view of a vacuum laminator, fig. 2 is a top view of the vacuum laminator of fig. 1, and referring to fig. 1 and fig. 2, according to the present invention, a vacuum laminator for attaching a film 501 to a substrate 502 includes a workbench 101, wherein the workbench 101 is provided with a vacuum chamber portion 401, a film pressing jig 5, a film feeding portion 3, a substrate feeding portion 2, and a film pressing portion 41. Wherein, the film pressing jig 5 can be accommodated in the vacuum chamber 401. The lamination jig 5 includes a diaphragm holding portion 51, a substrate holding portion 52, a first supporting portion 53, and a first positioning portion 54, wherein the diaphragm holding portion 51 adsorbs and holds the diaphragm 501; the substrate holding portion 52 adsorbs and holds the substrate 502, and is provided so as to cover the film holding portion 51 so that the film 501 and the substrate 502 face each other; the first support part 53 is provided to support the substrate holding part 52 or the film holding part 51 when the substrate holding part 52 and the film holding part 51 are closed; the first positioning portion 54 is provided to position the film holding portion 51 and the substrate holding portion 52 when the substrate holding portion 52 and the film holding portion 51 are covered. The film feeding section 3 is configured to take the film 501 and feed the film to the film holding section 51 after adjusting the position of the film 501; the substrate loading section 2 is configured to take the substrate 502 and load the substrate to the substrate holding section 52 after adjusting the position of the substrate 502.

In this embodiment, since the position-adjusted diaphragm 501 is fed to the diaphragm holding portion 51 of the lamination jig 5 by the diaphragm feeding portion 3, the position-adjusted substrate 502 is fed to the substrate holding portion 52 of the lamination jig 5 by the substrate feeding portion 2, and the diaphragm holding portion 51 and the substrate holding portion 52 are respectively positioned at the lamination jig 5, there is no need to position the diaphragm 501 and the substrate 502 in the vacuum chamber 401, and in addition, the size of the vacuum chamber 401 only needs to be adapted to the lamination jig 5 and the lamination portion 41, for example, the length and width of the vacuum chamber 401 only need to be slightly larger than the length and height of the lamination jig 5, so the structure is simpler and more compact.

In some embodiments, in order to improve the efficiency of the vacuum laminator, a rotating table 44 is further disposed on the table 101, the lamination jigs 5 include a plurality of positions respectively mounted on the rotating table 44, and each lamination jig 5 switches positions on the table 101 along with the rotation of the rotating table 44. Specifically, the avoidance groove 102 may be started at the middle portion of the table 101, the rotating table 44 may be accommodated in the avoidance groove 102, and the rotating table 44 may be connected to a DD motor known to those skilled in the art, or a combination of a servo motor and a divider (not shown, a lower portion of the table 101) to be rotated. For example, two film pressing jigs 5 may be installed on the rotating table 44, the two film pressing jigs 5 are distributed at 180 degrees in the circumferential direction of the rotating table 44 along the rotating table 44, and use the position of one of the film pressing jigs 5 as a feeding station, the film feeding portion 3 obtains the film 501 and feeds the film to the film pressing jig 5 as the feeding station after adjusting the position of the film 501, and the substrate feeding portion 2 obtains the substrate 502 and feeds the same film pressing jig 5 after adjusting the position of the substrate 502. After the feeding is completed, the DD motor (or a combination of a servo motor and a divider) drives the rotating table to rotate 180 degrees (pressing position), and enters the area of the vacuum chamber part 401, and film pressing is performed through the film pressing part 41. From this, material loading and press mold process can go on simultaneously, can improve the efficiency of press mold.

It is conceivable that the lamination jig 5 ensures the positional accuracy of the film holding portion 51 and the substrate holding portion 52 with respect to each other by the first positioning portion 54, thereby ensuring the accuracy between the film 501 and the substrate 502, and further ensuring the accuracy at the time of lamination, and therefore, the feeding accuracy of the film 501 and the substrate 502 needs to be ensured before the feeding of the film 501 and the substrate 502. The film feeding section 3 and the substrate feeding section 2 will be described in detail below.

In some embodiments, the film loading part 3 and the substrate loading part 2 are respectively located at two sides of the lamination jig 5, for example, in the case where the lamination jig 5 is mounted to the rotating table 44, the film loading part 3 and the substrate loading part 2 are respectively disposed at two sides of the lamination jig 5 located at the loading station to independently load the film 501 and the substrate 502 to the lamination jig 5, respectively. In the following embodiments, since the film sheet feeding section 3 and the substrate feeding section 2 have substantially the same structure, the film sheet feeding section 3 will be exemplified and described in detail, and the substrate feeding section 2 will be referred to simply as needed.

Fig. 3 is a schematic view of the film feeding unit 3, fig. 4 is a perspective view of the first feeding robot unit 32, and it should be noted that only some components related to the film feeding unit 3 are shown in fig. 3 and 4. Referring to fig. 3 and 4, and with additional reference to fig. 1 and 2, in the present embodiment, the film feeding unit 3 includes a film storage unit 31, a first feeding robot unit 32, and a first detection unit 35 (covered by a transparent acrylic plate in fig. 1). Here, the diaphragm adsorption portion 33 is provided at the end of the first loading robot part 32, the diaphragm adsorption portion 33 is mounted to the end of the first loading robot part 32 via the first adjustment platform 34, and the first detection portion 35 is provided to detect the position of the diaphragm 501 adsorbed to the diaphragm adsorption portion 33.

It is contemplated that the robot of the first feeding robot part 32 may be, for example, a two-axis robot, a three-axis robot, etc. known to those skilled in the art, and the end of the first feeding robot part 32 may be referred to as one end of the two-axis robot or the three-axis robot where the actuator is mounted, such as one end where a clamping jaw, a suction cup, etc. is mounted. The first adjustment stage 34 may be a UVW stage, such as a UVW stage manufactured by TOYO corporation. The first detection unit 35 may use an image sensor such as a CCD (charge coupled device image sensor) or other smart camera. The diaphragm suction unit 33 can selectively suck the diaphragm 501 by, for example, the vacuum chuck 331 (see fig. 4).

It should be noted that the first adjustment platform 34 needs to be adjusted according to the position of the membrane 501 detected by the first detection portion 35, that is, the first adjustment platform 34 needs to communicate with the first detection portion 35, and communication, control methods and the like between the first adjustment platform 34 and the first detection portion 35 are well known to those skilled in the art and will not be described in detail herein.

In the present embodiment, since the film feeding section 3 is provided with the first detection section 35 and the first feeding robot part 32 is provided with the first adjustment stage 34, after the first feeding robot part 32 is adsorbed to the film 501, the first adjustment stage 34 can accurately adjust the position of the film 501 according to the position of the film 501 detected by the first detection section 35, thereby improving the feeding accuracy of the film 501. In addition, since the exact position of the membrane 501 is determined before loading, no adjustment is required in the vacuum chamber 401, enabling the size of the vacuum chamber 401 to be more compact, e.g., only by fitting the lamination jig 5 for holding the membrane 501 and the substrate 502. When the size of the vacuum chamber section 401 is more compact, the specification of the vacuum laminator can be further reduced, thereby reducing the cost of the apparatus.

Fig. 5 is a perspective view of the film storage unit 31, and referring to fig. 5, in some embodiments, the film storage unit 31 includes a storage table 311 and a lifting motor 312, the film 501 is stacked on the storage table 311, and the lifting motor 312 is connected to the storage table 311 to drive the storage table 311 to lift. Accordingly, in the initial state, a plurality of the film pieces 501 can be stacked on the storage base 311, and the lifting motor 312 drives the storage base 311 to lift and lower according to the height of the stacked film pieces 501, so that the first loading robot part 32 can accurately suck the film pieces 501.

In order to determine the lamination height of the diaphragm 501, the diaphragm storage unit 31 may be provided with a photosensor 313, for example, a correlation type photosensor, for detecting the presence or absence of the diaphragm 501. Specifically, the position of the diaphragm 501 detected by the photoelectric sensor 313, that is, the position at which the first loading robot 32 drives the diaphragm suction unit 33 to descend, may be set as the suction position of the first loading robot 32, and the lift motor 312 drives the storage table 311 to ascend so that the diaphragm 501 can be detected by the photoelectric sensor 313. When the photoelectric sensor 313 does not detect the film 501 as the first loading robot part 32 is loaded, the lifting motor 312 drives the storage table 311 to ascend so that the film 501 stored in the storage table 311 can be detected by the photoelectric sensor 313.

In order to prevent the membrane suction part 33 from sucking a plurality of membranes 501 at a time, the membrane storage part 31 may further include a brush 314, the brush 314 is disposed at a position where the first feeding robot part 32 drives the membrane suction part 33 to ascend, and the membranes 501 sucked by the membrane suction part 33 collide with the brush 314 during feeding, so that the membranes 501 not sucked by the vacuum pads 331 of the membrane suction part 33 are brushed down by the brush 314, thereby ensuring that the membrane suction part 33 sucks only one membrane 501 at a time.

In some embodiments, storage table 311 is resiliently and telescopically coupled to lift motor 312. Specifically, for example, the lifting motor 312 is connected to the transfer stage 315, and drives the transfer stage 315 to lift, and the storage stage 311 is elastically and telescopically supported to the transfer stage 315 by, for example, support of the buffer spring 316 and guidance of a guide shaft (not shown, the buffer spring 316 is fitted on the guide shaft). Thus, when the vacuum chuck 331 of the diaphragm suction portion 33 sucks the diaphragm 501, the storage table 311 can adaptively absorb the pressure of the diaphragm suction portion 33, thereby preventing the vacuum chuck 331 of the diaphragm suction portion 33 from being damaged due to the diaphragm suction portion 33 directly hitting the storage table 311, and preventing wrinkles or the like from occurring when the diaphragm 501 is sucked. In addition, in the present embodiment, the diaphragm adsorbing portion 33 may be directly and rigidly attached to the first adjustment stage 34, thereby further improving the accuracy with which the first adjustment stage 34 adjusts the position of the diaphragm 501.

In some embodiments, the storage table 311 is disposed at an upper portion of the table 101 (referring to fig. 1), and the lift motor 312 is disposed at a lower portion of the table 101. Specifically, a motor mounting base 317 is arranged at the lower part of the workbench 101, the lifting motor 312 is mounted on the motor mounting base 317, and the lifting motor 312 is connected with an adapter 315 positioned at the upper part of the workbench 101 through a screw transmission mechanism. This makes it possible to make the installation space of the table 101 sufficiently utilized and to make the upper part of the table 101 more compact.

In some embodiments, the film sheet storage part 31 further includes a film sheet positioning part 37, and the film sheet positioning part 37 is disposed at a side of the storage table 311 and is disposed to be adjustable with respect to the storage table 311. Specifically, one side of the storage table 311 is provided with a reference plate 373, the diaphragm positioning portion 37 is provided on the opposite side of the storage table 311 from the reference plate 373, the diaphragm positioning portion 37 includes a positioning plate 374, an adjusting bolt 375 and a sliding shaft 376, the positioning plate 374 is respectively connected with the adjusting bolt 375 and the sliding shaft 376, and by rotating the adjusting bolt 375, the positioning plate 374 is brought close to the storage table 311 or is brought away from the storage table 311, thereby adjusting the distance between the positioning plate 374 and the reference plate 373, so that the diaphragm storage portion 31 can be adapted to diaphragms 501 of different sizes, and the versatility is higher.

In some embodiments, the diaphragm positioning portion 37 includes an X-axis positioning portion 371 and a Y-axis positioning portion 372, the X-axis positioning portion 371 is adjustably disposed at the side of the storage table 311 in the X-axis direction, and the Y-axis positioning portion 372 is adjustably disposed at the side of the storage table 311 in the Y-axis direction. Correspondingly, the first reference plate 373a is provided on the other side of the storage table 311 in the X-axis direction, and the second reference plate 373b is provided on the other side of the storage table 311 in the Y-axis direction. Thus, the distance between the X-axis positioning portion 371 and the first reference plate 373a and the distance between the Y-axis positioning portion 372 and the second reference plate 373b can be adjusted, so that the diaphragm storage portion 31 can accommodate more diaphragms 501 of different sizes, and the versatility is higher.

Fig. 6 is a perspective view of the first detecting part 35, and referring to fig. 6, in some embodiments, in order to accommodate diaphragms 501 of different sizes, the first detecting part 35 includes a CCD351 and an adjusting motor 352, and the adjusting motor 352 is connected to the CCD351 and drives the CCD351 to change a detecting position. Thus, the adjustment motor 352 drives the CCD351 to change the detection position in accordance with the size of the diaphragm 501 to accommodate diaphragms 501 of different sizes. The adjustment motor 352 may include two motors for adjusting the position of the CCD351 in the X-axis direction and the position of the CCD in the Y-axis direction, respectively. The adjustment motor 352 can drive the CCD351 to change the detection position by a transmission mechanism such as a screw transmission mechanism.

In some embodiments, the first detection part 35 includes two positions, and detects opposite corners of the diaphragm 501 respectively. Thus, the contour of the diaphragm 501 can be detected completely, and the first adjustment stage 34 can adjust the position of the diaphragm 501 based on the accurate contours of the diaphragm 501 detected by the two first detection units 35.

With continued reference to fig. 1 and 3, in some embodiments, the first detection portion 35 is disposed below the first feeding robot portion 32, and a first light source portion 38 for assisting the first detection portion 35 in detecting is mounted at a distal end of the first feeding robot portion 32, and the first light source portion 38 may be an LED light source known to those skilled in the art. By disposing the first detection portion 35 below the first feeding robot portion 32, the driving stroke of the first feeding robot portion 32 can be reduced, for example, the first detection portion 35 may be disposed between the film storage portion 31 and the path of the film lamination jig 5 for holding the film 501, when the first feeding robot portion 32 is adsorbed to the film 501 from the film storage portion 31, the first detection portion 35 is passed through and the accurate position of the film 501 is detected, the first adjustment platform 34 adjusts based on the accurate position of the film 501 detected by the first detection portion 35, and then the first feeding robot portion 32 blanks the film 501 to the film lamination jig 5. It is to be understood that the first detection part 35 may also be provided below the table 101 to further reduce the driving stroke of the first feeding robot part 32.

With continued reference to fig. 4, in some embodiments, a second detection portion 36 is further provided, and the second detection portion 36 is configured to detect the position of the film holding portion 51 before the film feeding portion 3 feeds the film 501 to the film holding portion 51. For example, the second detection section 36 is attached to the tip of the first loading robot section 32. Accordingly, after the film suction unit 33 sucks the film 501 and the first adjustment stage 34 performs precise adjustment, the second detection unit 36 precisely detects the position of the film holding unit 51 (i.e., the position of the lamination jig 5 on which the film 501 is placed), and the first loading robot 32 can accurately place the film 501 on the film holding unit 51. It is conceivable that the second detection section 36 is not limited to be mounted at the tip of the first feeding robot section 32, and the second detection section 36 can be provided at any position of the table 101 as long as the position of the film holding section 51 for holding the film 501 can be detected.

Fig. 7 is a schematic view of the lamination jig 5 in an open state, fig. 8 is a schematic view of the lamination jig 5 in a closed state, fig. 9 is a schematic view of the substrate holding portion 52, fig. 10 is a schematic view of the lamination jig 5 without the substrate holding portion 52, fig. 11 is an exploded view of the lamination jig 5, and the lamination jig 5 for holding and positioning the diaphragm 501 and the substrate 502, respectively, will be described in detail below with reference to fig. 7 to 11 and with additional reference to fig. 1.

Referring to fig. 1, 7 and 8, as described above, the lamination jig 5 includes the film holding portion 51, the substrate holding portion 52, the first support portion 53 and the first positioning portion 54. Wherein the membrane holding portion 51 adsorbs and holds the membrane 501; the substrate holding portion 52 sucks and holds the substrate 502, and the substrate holding portion 52 is provided so as to cover the film holding portion 51 so that the film 501 and the substrate 502 face each other, but it is to be understood that the covering of the substrate holding portion 52 and the film holding portion 51 does not mean that both are necessarily pressed against each other, but only that both face each other, and can approach each other when an external force is applied to both; the first support part 53 is provided to support the substrate holding part 52 or the film holding part 51 when the substrate holding part 52 and the film holding part 51 are closed; the first positioning portion 54 is provided to position the film holding portion 51 and the substrate holding portion 52 when the substrate holding portion 52 and the film holding portion 51 are covered.

In the present embodiment, since the film holding portion 51 for sucking and holding the film 501 and the substrate holding portion 52 for sucking and holding the substrate 502 are provided, and the first supporting portion 53 and the first positioning portion 54 are provided between the film holding portion 51 and the substrate holding portion 52, it is possible to ensure the positional accuracy of the film 501 and the substrate 502 before vacuum lamination. In addition, because the film pressing jig is positioned by a mechanical type, the structure is compact, and the positioning in the vacuum chamber part 401 is not needed, so that the size of the vacuum chamber part 401 only needs to be matched with the film pressing jig 5, and the size of the vacuum chamber part 501 can be more compact.

In some embodiments, the diaphragm holding portion 51 includes a flexible holder 511, and the flexible holder 511 adsorbs and holds the diaphragm 501. The material of the flexible holder 511 may be selected from, for example, silicone, etc., and of course, the material of the flexible holder 511 may be selected from other flexible materials known to those skilled in the art to be capable of holding the membrane 501. Since static electricity exists between the diaphragm 501 and the flexible holder 511, the diaphragm 501 can be stably and directly attracted to the flexible holder 511. Therefore, by providing the flexible holder 511, the diaphragm 501 can be directly sucked and held.

It is conceivable that, in the present embodiment, the diaphragm holding portion 51 and the first supporting portion 53 are mounted to the jig base 56, respectively, and the substrate holding portion 52 may be mounted to the first supporting portion 53. In other embodiments, the substrate holding portion 52 and the first support portion 53 may be attached to the jig base 56, and the diaphragm holding portion 51 may be attached to the first support portion 53.

In some embodiments, the first support portion 53 is provided on one side of the film holding portion 51, and the substrate holding portion 52 and the first support portion 53 are hinged and swingably opened or closed with respect to the film holding portion 51. Specifically, the first support portion 53 and the diaphragm holding portion 51 are respectively mounted to the jig base 56, the first support portion 53 is located on one side (for example, one side in the longitudinal direction) of the diaphragm holding portion 51, and the substrate holding portion 52 is hinged by the hinge shaft 531 and the first support portion 53. This enables initial positioning of the positions of the substrate holding portion 52 and the membrane holding portion 51 relative to each other.

In some embodiments, in order to support the substrate holding portion 52 more stably to ensure the accurate position of the substrate holding portion 52 and the film holding portion 51 after being covered with each other, a second support portion 55 is further included, and the second support portion 55 and the first support portion 53 are respectively disposed on both sides of the film holding portion 51 to support the substrate holding portion 52 together.

In some embodiments, the first support portion 53 and the second support portion 55 elastically support the substrate holding portion 52, respectively, and the substrate holding portion 52 moves toward the diaphragm holding portion 51 and covers the diaphragm holding portion 51 when pressure is applied thereto. Specifically, the two sides of the length direction of the jig base 56 are respectively provided with a first accommodating cavity 561 and a second accommodating cavity 562, the first accommodating cavity 561 is used for accommodating the first supporting portion 53, the second accommodating cavity 562 is used for accommodating the second supporting portion 55, a jig cover plate 563 is arranged on the first accommodating cavity 561 and the second accommodating cavity 562, and the jig cover plate 563 is locked on the jig base 56 and used for limiting the first supporting portion 53 and the second supporting portion 55.

In some embodiments, the working platform 101 is further provided with a covering portion 42, the covering portion 42 has a first cover 421 and a covering driving portion 422, the covering driving portion 422 is connected with the first cover 421, and the first cover 421 is driven to be hermetically pressed on the working platform 101, so that a vacuum chamber portion 401 is formed between the inner cavity 423 of the first cover 421 and the working platform 101. Specifically, the peripheral side of the inner cavity 423 of the first cover 421 is closed (for example, when a visual window or other joints are provided, the peripheral side is sealed and fastened), and an opening is provided at the surface pressed with the workbench 101, so that the mounting surface of the workbench 101 can be directly used as a part for forming the vacuum chamber portion 401, and the covering portion 42 capable of hermetically pressing the workbench 101 is further provided, which not only has a compact structure, but also has simple control. Of course, it is conceivable that the vacuum chamber portion may be a vacuum chamber portion having a separate chamber body as well known to those skilled in the art.

It is conceivable that, in the embodiment in which the rotary table 44 is provided on the table 101, the cover driving section 422 drives the first cover 421 to sealingly press the rotary table 44, so that the vacuum chamber section 401 is formed between the inner chamber 423 of the first cover 421 and the rotary table 44. The lamination jig 5 is installed on the rotary table 44, and the following description will be given in detail. In this embodiment, the lamination jig 5 may be directly locked to the rotary table 44, and it is conceivable that when sealing is required between the lamination jig 5 and the rotary table 44, a first sealing ring (not shown) may be provided between the lamination jig 5 and the rotary table 44 to make the lamination jig 5 be locked to the rotary table 44 in a sealing manner. The second packing 424 is provided on the surface where the first cover 421 and the rotary table 44 are pressed together, and when the first cover 421 is pressed against the rotary table 44, the vacuum chamber 401 is formed between the inner chamber 423 of the first cover 421 and the rotary table 44 by sealing with the second packing 424. The cover driving unit 422 may be a motor, an air cylinder, a hydraulic cylinder, or the like known to those skilled in the art, and preferably an air cylinder.

The inside of the vacuum chamber 401 may be evacuated by any known means, for example, by using an evacuation device (not shown) such as a negative pressure pump or a vacuum generating pump, and an interface for evacuation (for example, an aviation plug) may be provided on the rotary table 44 or the first cover 421 as needed.

In some embodiments, in order to make the structure of the vacuum laminator 4 more compact, the laminator 41 may be mounted to the first cover 421, and at least the ram 411 is received in the inner cavity 423 of the first cover 421. Therefore, the height of the vacuum chamber 401 is only required to be slightly higher than the height of the lamination jig 5, the height of the pressure head 411 and the driving stroke of the lamination driving part 412, so that the structure of the vacuum laminator 4 can be more compact. In this embodiment, the squeeze film driving unit 412 may be an air cylinder, and the cylinder 412a of the air cylinder of the squeeze film driving unit 412 is hermetically attached to the outside of the first cover 421 (for example, a third seal ring (not shown) is provided between the attachment surface of the cylinder 412a of the air cylinder and the outer side surface of the first cover 421), and the piston rod of the air cylinder extends into the inner cavity 423 of the first cover 421 and is connected to the ram 411.

In actual operation, first, the covering driving portion 422 of the covering portion 42 drives the first covering 421 to extend toward the rotating table 44 and press the rotating table 44, so as to form a vacuum chamber 401 between the inner cavity 423 of the first covering 421 and the rotating table 44, and at this time, the film pressing jig 5 and the pressing head 411 of the film pressing portion 41 are respectively accommodated in the vacuum chamber 401. After the vacuum chamber 401 is evacuated by the vacuum evacuation device, the squeeze film driving section 412 of the squeeze film section 41 drives the ram 411 to abut against the substrate holding section 52 (or the film holding section 51) and the substrate holding section 52 and the film holding section 51 are brought close to each other to press the film 501 and the substrate 502 together. Since the lamination of the film 501 and the substrate 502 is performed in a vacuum environment, wrinkles, bubbles, and the like can be prevented from occurring when the film 501 and the substrate 502 are laminated.

In order to further improve the lamination quality of the membrane 501 and the substrate 502, in some embodiments, a heating portion (not shown) is further disposed in the vacuum chamber 401.

In the lamination, the temperature of the vacuum chamber 401 may be raised to 60 ℃, and of course, a person skilled in the art sets the heating temperature of the vacuum chamber 401 according to the actual situation. This enables the film sheet 501 to be bonded to the base material 502 while heating the vacuum chamber 401 to soften the film sheet 501, thereby further preventing wrinkles or bubbles from occurring when the film sheet 501 and the base material 502 are bonded, and further improving the lamination quality of the film sheet 501 and the base material 502.

It is conceivable that, in the present embodiment, a heat insulating plate 413 may be provided between the squeeze head 411 and the squeeze film driving part 412 of the squeeze film to prevent heat in the vacuum chamber part 401 from being transferred to the squeeze film driving part 412.

When the film pressing part 41 is mounted on the first cover 421, since the film pressing part 41 presses the substrate holding part 52 (or the film holding part 51), a reaction force is generated on the first cover 421, and when the reaction force is too large, a state that the first cover 421 presses the rotating table 44 may be loosened, thereby causing vacuum breaking, and in some embodiments, the film pressing part 43 further includes a suction part 43, the suction part 43 is disposed on the first cover 421, and the suction part 43 is sucked to the rotating table 44 when the first cover 421 presses the rotating table 44. This can assist the cover driving unit 422, and can stably and tightly press the first cover 421 against the rotary table 44. In order to save cost, the suction portion 43 may use electromagnets, for example, including two electromagnets, which are respectively disposed at both sides of the first cover 421. Of course, the suction portion 43 may be vacuum-sucked, for example, a vacuum chuck or the like.
