Such a flat plate-like member suction device is a device in which a suction plate having a plurality of suction holes formed thereon is brought into contact with a flat plate-like member to be sucked, and the flat plate member is sucked under negative pressure. At this time, in order to prevent the suction force from being lowered, it is important to reduce the suction leakage as much as possible. The term " suction leakage " refers to a state in which a part of the suction holes of the plurality of suction holes is exposed from the flat plate-like member when the suction operation of the flat plate-like member is performed.

In order to reduce the suction leakage as much as possible, it is important to set the suction area on the suction plate to be substantially equal to or slightly smaller than the size of the plate-like member when facing the plate-like member to the suction plate. Here, the " suction region " refers to a region in the suction hole formed in the suction plate, in which the flat plate member to be sucked can be sucked. Further, the suction region can be formed in various shapes, but here, the shape is rectangular.

Here, if the size of the flat plate member to be sucked is one, if the suction region is set to be substantially equal to or slightly smaller than the size of the flat plate member, It may be desired to perform suction of the flat plate member having a size smaller than the size of the suction region. In such a case, if the size of the suction region is fixed, the flat plate member having a size smaller than the size of the suction region can not cover the entire suction region, and suction leakage occurs.

However, in the flat plate shaped suction apparatus 900 described in Patent Document 1, it is necessary to prepare a sheet portion having a suction region corresponding to the size of the substrate for each size of the substrate to be sucked, It is necessary to provide a roll serving as a mechanism for disposing the sheet portion having the suction region corresponding to the size on the suction plate and a driving portion for driving the roll and a control portion for controlling the driving portion. As a result, in the flat plate-like suction apparatus 900 described in Patent Document 1, there is a problem that the whole structure of the suction apparatus becomes large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a flat plate shaped aspirator which can form a suction region corresponding to the size of a flat plate member to be sucked, And it is an object of the present invention to provide a suction device.

[1] A plate-shaped member suction apparatus according to the present invention is a plate-like member suction apparatus for suctioning a flat plate member by negative pressure, comprising: a base plate provided in a suction device body forming a negative pressure chamber; And a member-facing plate which is stacked on the base plate in a state of being in a planar close state and is capable of making a reference position and a slide position slidable from the reference position with respect to the base plate, Wherein a plurality of suction holes are formed in the member facing plate as suction holes on the member facing plate side and the suction holes on the base plate are formed in a predetermined arrangement on the base plate, Member facing plate side Wherein the plurality of reference suction holes are formed so as to face all the suction holes of the base plate side suction holes or the base plate side suction holes when the member face plate is in the reference position, And a further suction hole formed between a reference suction hole adjacent to the member-facing plate in the predetermined area of the member-facing plate along the sliding direction of the member-facing plate, and when the member-facing plate is at the reference position, The reference suction region is formed in the member-facing plate by opposing the hole and the suction hole on the base plate formed at the same position as the reference suction hole, and when the member-facing plate is in the slide position, Additional aspiration And a specific suction region having a size different from that of the reference suction region is formed on the member facing plate by opposing the hole and the suction hole on the base plate formed at the same position as the additional suction hole.

According to the flat plate-like member suction device of the present invention, when the member-facing plate is in the reference position and in the slide position, the suction region for allowing the plate member to be sucked is referred to as a reference suction region and the reference suction region has a different size Can be formed. As described above, according to the flat plate member suction apparatus of the present invention, the size of the suction region can be changed by simply changing the position of the member-facing plate relative to the base plate. Thus, the suction region corresponding to the size of the flat plate member to be sucked can be formed by a simple operation without making the entire configuration of the flat plate shaped member suction apparatus large-scale. Specifically, a suction region (specific suction region) smaller than the suction region (reference suction region) originally possessed by the flat plate member suction apparatus of the present invention can be formed. Thus, even when the flat plate member having a size smaller than that of the flat plate member having a size suitable for the suction region (reference suction region) originally possessed by the flat plate member suction apparatus of the present invention is sucked, Suction can be performed without leakage.

When the member-facing plate is moved from the reference position and the reference position to the slide position in which the member-facing plate is slid from the reference position, the position of the base plate may be fixed together with the suction apparatus main body to slide the member- Conversely, the position of the member-facing plate may be fixed and the base plate may be slid together with the suction device body.

[2] In the flat plate-like suction device according to the present invention, when the member-facing plate is at the reference position and when the member-facing plate is at the slide position, the member- Or a position determining section for determining the position of the slide position relative to the slide position.

By having such a positioning portion, the suction holes of the member-facing plate-side suction holes of the member-facing plate and the suction holes of the base plate-side suction holes of the base plate can be accurately confronted with each other and both confronting relationship can be maintained. Thus, even during the suction operation, a proper sucking operation can be performed for a long period of time without collapsing the opposing relationship between the sucking holes of the member-facing plate side suction holes of the member-facing plate and the suction holes of the base plate-

[3] In the flat plate-like member suction device of the present invention, the positioning portion may include: a base plate side positioning hole formed to penetrate the base plate; and a positioning hole provided in the member-facing plate, A plurality of member-facing-plate-side positioning holes opposed to the base plate-side positioning holes in each of the reference position and the slide position when in the reference position or the slide position, And a positioning pin insertable into the positioning hole on the side of the member facing plate facing the base plate side positioning hole.

With such a configuration of the positioning portion, the mechanism of the positioning portion can be simplified. The operation for positioning is performed only by a simple operation of inserting the positioning pin into the positioning hole on the base plate side and the positioning hole on the side of the member facing plate side facing the positioning hole on the base plate side And it is possible to perform reliable positioning only by performing such an operation.

[4] In the flat plate member suction device of the present invention, the positioning portion may include a driving device for sliding the member-facing plate and a control device for controlling the driving device, It is also preferable that the member-facing plate is positioned at the reference position or the slide position by controlling the apparatus.

With such a configuration of the positioning portion, the positioning of the member-facing plate can be automatically performed. For example, by operating the selection button for selecting the slide position, the operator can automatically set the slide position to the predetermined slide position or the slide position to the reference position. As the driving device, for example, a driving device having a motor and an actuator can be exemplified. When such a positioning unit is constituted, the size of the flat plate member to be sucked is recognized based on the image data of the image of the flat plate member to be sucked, using image processing technology, and based on the recognition result, It is possible to automatically control the member-facing plate to be in a predetermined position.

[5] In the plate-shaped member suction device of the present invention, there is a region where the additional suction holes formed between the adjacent reference suction holes are formed in n (n is an integer of 2 or more) And the n additional suction holes are sequentially arranged from the first-stage additional suction hole to the n-th additional suction hole along the sliding direction, the slide position is set to n Wherein the n additional suction holes are sequentially opposed to the suction holes on the base plate side of the base plate for each of the slide positions of the n stages so that the specific suction region It is preferable that they are formed in different sizes.

Thereby, in the member-facing plate, in addition to the reference suction region formed when the member-facing plate is at the reference position, n kinds of specific suction regions .

[6] In the flat plate member aspirating apparatus of the present invention, the reference suction hole and the additional suction hole may be formed so that, in some of the reference suction region and the specific suction region, Face plate so that the number of the reference suction holes and the number of the additional suction holes is larger than the area other than the partial area.

As described above, in the reference suction region and some of the specific suction regions, the reference suction holes and the additional suction holes of the member-facing plate are formed in a larger number than the regions other than the partial regions, And in a certain region of the specific suction region, more reliable suction can be performed than in a region other than the partial region. By doing so, it is suitable when, for example, a predetermined region of the flat plate-shaped member needs to be sucked more reliably.

[7] In the flat plate-like member suction device of the present invention, it is preferable that the part of the area is an area opposed to a region on one end side of the flat plate member.

As described above, since a part of the area is an area opposed to one end side of the flat plate member, for example, when the peel which is peelably adhered to the sheet is peeled from the sheet, As shown in Fig. That is, when peeling off a film from a film having such a ground, it is important to surely peel off the front end of the film, and for this purpose, it is preferable to more reliably hold the front end region. Therefore, in this case, if the reference suction region or a part of the specific suction region is set so as to face the region on the front end side of the film, peeling of the film can be reliably performed.

[8] In the plate-like member suction device of the present invention, the flat plate member is preferably a sheet-like member.

As described above, since the flat plate member is a sheet-like member, various sizes of films, flexible substrates, and the like can be sucked.

[9] In the plate-shaped member suction apparatus of the present invention, the sheet-like member is preferably a cover-lay film.

As described above, since the sheet-like member is a cover-ray film, it is suitable as a suction device for holding and holding the cover-lay film when peeling the cover-lay film which is peelably adhered to the ground from the ground.

Further, the base suction hole 211 has a circular shape when viewed along the z-axis.

On the other hand, as shown in FIG. 2 (b), a plurality of member-facing-plate-side suction holes 221 are formed in the member-facing plate 220. Similar to the base suction hole 211, the member-facing suction hole 221 also has a circular shape when viewed along the z-axis.

The member-facing-plate-side suction holes 221 are formed in such a manner that when the member-facing plate 220 is at the reference position Pa with respect to the base plate 210, (In the vicinity of the center of the member-facing plate 220 in FIG. 2 (b) of the member-facing plate 220 among the reference suction holes 221a) (Referred to as a region C1 indicated by a broken line and a region C2 indicated by a chain double-dashed line) of the member facing plate 220 in the sliding direction (direction of arrow yy ') of the member facing plate 220 And an additional suction hole.

In the member-facing plate 220, there is a region in which a plurality of (two of) additional suction holes are formed between adjacent reference suction holes along the sliding direction (direction of the arrow yy ') (for example, A region substantially equivalent to the region C2 indicated by the chain double-dashed line in Fig. 2 (b)]. These two additional suction holes are referred to as additional suction holes 221b and 221c. Further, the additional suction holes 221b and 221c also have a circular shape when viewed along the z-axis, like the base suction hole 211. [

Of the two additional suction holes 221b and 221c, the additional suction holes located on the front side in the slide direction (the direction of the arrow y direction) are referred to as " first additional suction holes 221b " And the additional suction hole located on the rear side of the second suction hole 221b is referred to as " second additional suction hole 221c ". The reference suction holes 221a are indicated by white circles in the same manner as the base suction holes 211 of the base plate 210 and the first additional suction holes 221b are indicated by gray circles And the second additional suction holes 221c are indicated by black circles.

The first additional suction holes 221b shown in gray are arranged side by side on virtual lines (on the line along the x axis) orthogonal to the slide direction (yy 'direction), and the "second additional suction holes 221b" The additional suction hole 221c "is also arranged in a virtual line (on the line along the x axis) orthogonal to the slide direction (yy 'direction). Here, a hypothetical line along the x axis along which the first additional suction holes 221b are arranged is a hypothetical line at the first level along the sliding direction between the adjacent reference suction holes along the sliding direction, The hypothetical line along the x axis along which the suction holes 221b are arranged is a hypothetical line at the second level along the sliding direction between the adjacent reference suction holes along the sliding direction.

As a result, each first additional suction hole 221b exists as a first-stage additional suction hole in the reference suction hole adjacent to the sliding direction, and each second additional suction hole 221c is formed in the same And is present as a second-stage additional suction hole.

As a result, when the member-facing plate 220 is slid to the respective slide positions (the first slide position Pb and the second slide position Pc), the first additional suction holes And the second additional suction hole 221c existing as the second-stage additional suction hole slide by the same amount of sliding. Each of the first additional suction holes 221 existing as additional suction ports of the first stage and the additional suction holes of the second stage as the additional suction holes 221 are provided for each of the slide positions (the first slide position Pb and the second slide position Pc) Each of the second additional suction holes 221c existing in this order opposes the base suction hole 211 of the base plate 210 in order.

Specifically, when the member-facing plate 220 reaches the first slide position Pb, each first additional suction hole 221b existing as the first-stage additional suction hole is guided to the base suction side of the base plate 210 Each second additional suction hole 221c existing as a second-stage additional suction hole is provided on the base plate (second suction position) when the member-facing plate 220 reaches the second slide position Pc, 210, respectively.

The area C1 indicated by the broken line in FIG. 2 (b) is a suction region (not shown) formed in the member-facing plate 220 when the member-facing plate 220 is set to the first slide position Pb Ab) (see Fig. 4). The area C2 indicated by the chain double-dashed line in FIG. 2 (b) is a suction area formed in the member-facing plate 220 when the member-facing plate 220 is set to the second slide position Pc. (See Fig. 5). These suction regions (Ab, Ac) will be described later.

The reference suction holes 221a are formed at predetermined intervals d1 along the x-axis and the y-axis, like the base suction holes 211. [ On the other hand, the two additional suction holes (the first additional suction holes 221b and the second additional suction holes 221c) formed between the adjacent reference suction holes 221a in the slide direction (the direction of the arrow yy ' Is formed at a position every interval d2 in which the distance d1 in the sliding direction of the adjacent reference suction holes 221a is equally divided (three in this case).

The diameter of the base suction hole 211 of the base plate 210 and the diameter of the suction hole 221 of the member facing plate 220 (the reference suction hole 221a, the first additional suction hole 221b, Diameter of the suction hole 221 (the reference suction hole 221a, the first additional suction hole 221b and the second additional suction hole 221c) of the member-facing plate 220 Is smaller than the diameter of the base suction hole (211) of the base plate (210).

The diameter of the base suction hole 211 of the base plate 210 and the diameter of the suction hole 221 of the member facing plate 220 are set as described above so that the base suction hole 211 of the base plate 210 is provided with the member- Even if the center of the suction hole 221 of the member-facing plate 220 slightly deviates slightly from the center of the base suction hole 211 when the suction operation is performed by opposing the suction hole 221 of the suction member 220, Leakage can be prevented from occurring.

In the base plate 210 and the member face plate 220 thus configured, when the member face plate 220 is at the reference position Pa with respect to the base plate 210 and when the member face plate 220 (The first slide position Pb and the second slide position Pc) that are opposed to the base suction hole 211 of the base plate 210, 220 are different from each other.

That is, when the member-facing plate 220 is at the reference position Pa with respect to the base plate 210, the suction holes (not shown) of the member-facing plate 220 opposed to the base suction hole 211 of the base plate 210 221 becomes the reference suction hole 221a. When the member-facing plate 220 is in the first slide position Pb with respect to the base plate 210, the suction of the member-facing plate 220 facing the base suction hole 211 of the base plate 210 The hole becomes the first additional suction hole 221b. When the member-facing plate 220 is in the second slide position Pc with respect to the base plate 210, the suction of the member-facing plate 220 facing the base suction hole 211 of the base plate 210 The hole becomes the second additional suction hole 221c.

As described above, when the member-facing plate 220 is at the reference position Pa, the first slide position Pb, and the second slide position Pc with respect to the base plate 210, The suction holes 221 of the member-facing plate 220 opposed to the base suction holes 211 are different. This allows the member-facing plate 220 to be moved to the suction position in which the suction force is applied to the base plate 210 at the reference position Pa, the first slide position Pb, and the second slide position Pc, Each having a different size.

As a result, the base suction holes 211 of the base plate 210 and the reference suction holes 221a of the member-facing plate 220 are in a through state. Therefore, the suction area formed on the member-facing plate 220 is a rectangular area Aa indicated by the one-dot chain line in Fig. 3, and the rectangular area Aa (suction area Aa) And has a size similar to that of the suction area A0 in the base plate 210. [ The suction region Aa is a suction region formed in the member-facing plate 220 when the member-facing plate 220 is at the reference position Pa. Therefore, the suction region Aa is referred to as a "reference suction region Aa" There are also cases.

When the member-facing plate 220 is at the reference position Pa with respect to the base plate 210, the reference position positioning holes 220a are aligned with the base positioning holes 210a of the base plate 210, . In this state, by inserting the positioning pin 410 (see FIG. 1) from the base positioning hole 210a of the base plate 210, the positioning pin 410 is positioned on the base plate 210 Is inserted into the reference position positioning hole 220a of the member facing plate 220 through the hole 210a.

Thereby, the member-facing plate 220 is precisely positioned at the reference position Pa with respect to the base plate 210, and the reference suction hole 221a (indicated by a white circle) and the reference suction hole 221a, And the base suction holes 211 of the base plate 210 at the same position are exactly opposite to each other, and the opposing relationship between them can be maintained.

In this state, the reference suction area Aa faces the flat plate member (for example, a cover film) having a size substantially equal to or slightly larger than the reference suction area Aa, The suction leakage from the suction holes of the suction plate 200 (the base plate 210 and the member face plate 220) is eliminated by disposing the member-facing plate 220 and sucking the plate member, The shape member can be reliably sucked.

4 is a schematic diagram showing a suction region formed in the member-facing plate 220 when the member-facing plate 220 is at the first slide position Pb.

4, when the member-facing plate 220 is at the first slide position Pb, the reference suction holes 221a formed in the member-facing plate 220 are connected to the base plate 210 (Indicated by a broken line) existing in each of the base suction holes 211 (indicated by broken lines) formed in the first stage suction holes 211, and instead, the first additional suction holes 221b Are respectively opposed to the base suction holes 211 existing at the same position as the first additional suction holes 221b among the base suction holes 211 of the base plate 210. [

As a result, the first additional suction hole 221b (indicated by a gray circle) and the base suction hole 211 located at the same position as the first additional suction hole 221b are in a through state. Therefore, the suction area at this time is a rectangular area Ab indicated by the one-dot chain line in Fig. 4, and the rectangular area Ab (referred to as suction area Ab) Is smaller than the suction region A0 (reference suction region Aa in the member face plate 220). In addition, in order to distinguish the suction region Ab from the reference suction region Aa, there may be a case where it is sometimes referred to as " specific suction region Ab ".

When the member-facing plate 220 is at the first slide position Pb with respect to the base plate 210, the first slide position positioning hole 220b is aligned with the base positioning hole 220b of the base plate 210, Lt; / RTI > In this state, by inserting the positioning pin 410 (see FIG. 1) from the base positioning hole 210a of the base plate 210, the positioning pin 410 is positioned on the base plate 210 And enters the first slide position positioning hole 220b of the member facing plate 220 through the hole 210a.

Thereby, the member-facing plate 220 is accurately positioned at the first slide position Pb with respect to the base plate 210, and each first additional suction hole 221b (indicated by a gray circle) The base suction holes 211 of the base plate 210 existing at the same position as the first additional suction holes 221c can accurately confront each other and maintain the opposite relationship therebetween.

In this state, in order to face a specific suction region Ab against a flat plate member (for example, a coverlay film) having a size substantially equal to or slightly larger than the specific suction region Ab, The suction leakage from the suction holes of the suction plate 200 (the base plate 210 and the member face plate 220) is eliminated by disposing the facing plate 220 and sucking the flat plate member, The shape member can be reliably sucked.

5 is a schematic diagram showing a suction region formed in the member-facing plate 220 when the member-facing plate 220 is at the second slide position Pc.

5, when the member-facing plate 220 is in the second slide position Pc, the reference suction holes 221a formed in the member-facing plate 220 and the first additional suction holes 221b formed in the member- The second suction holes 221b are located at positions deviated from the respective base suction holes 211 (indicated by broken lines) formed in the base plate 210 and instead of the second suction holes 211 The additional suction holes 221c (indicated by black circles) are provided in the base suction holes 211 of the base plate 210 at the same positions as the second additional suction holes 221b, Respectively.

As a result, the second additional suction hole 221c (indicated by a black circle) and the base suction hole 211 existing at the same position as the second additional suction hole 221c are in a through state. Therefore, the suction area at this time is a rectangular area Ac indicated by the one-dot chain line in Fig. 5, and the rectangular area Ac (referred to as suction area Ac) Is smaller than a specific suction region Ab (see Fig. The suction region Ac may also be referred to as a "specific suction region Ac" in order to distinguish it from the reference suction region Aa.

When the member-facing plate 220 is set to the second slide position Pc with respect to the base plate 210 as described above, the second slide position positioning hole 220c is formed in the base plate 210 And faces the base positioning hole 210a. 1) is inserted from the base positioning hole 210a of the base plate 210, the positioning pin 410 is positioned at the base position of the base plate 210 Is inserted into the second slide position positioning hole 220c of the member facing plate 220 through the crystal hole 210a.

Thus, the member-facing plate 220 is accurately positioned at the second slide position Pc with respect to the base plate 210, and each second additional suction hole 221c (indicated by a black circle mark) The base suction holes 211 of the base plate 210 existing at the same position as the second additional suction holes 221c can exactly confront each other and can maintain the opposite relationship therebetween.

In this state, in order to face the plate-like member (for example, a coverlay film) having a size substantially equal to or slightly larger than the specific suction region Ac, the specific suction region Ac faces the member The suction leakage from the suction holes of the suction plate 200 (the base plate 210 and the member face plate 220) is eliminated by disposing the facing plate 220 and sucking the flat plate member, The shape member can be reliably sucked.

As described above, according to the flat plate-like member suction device 10 of the first embodiment, the suction plate 200 is connected to the base plate 210 and the member-facing plate 220 (which is slidable with respect to the base plate 210) And the operation of setting the member facing plate 220 to either the reference position Pa, the first slide position Pb, or the second slide position Pc with respect to the base plate 210 , A suction region having a different size can be formed.

That is, when the member-facing plate 220 is set at the reference position Pa, a suction region (reference-possible region Aa) similar to the suction region A0 of the base plate 210 can be formed. When the member-facing plate 220 is in the first slide position Pb, a specific suction region Ab smaller than the suction region A0 of the base plate 210 can be formed, and the member-facing plate 220 are set to the second slide position Pc, a specific suction region Ac that is smaller than the specific suction region Ab can be formed. As a result, it is possible to reduce the size of the flat plate member having a size suitable for the suction region (in this case, the suction region A0 of the base plate 210) originally possessed by the flat plate member suction apparatus 10 according to the first embodiment Even when the flat plate member is sucked, the flat plate member of the small size can be sucked without suction leakage.

In the flat plate shaped suction apparatus 10 according to the first embodiment, when the member facing plate 220 is set and slid to the reference position Pa, either the first slide position or the second slide position, There is provided a positioning portion 400 for positioning the facing plate 220. [

When the member facing plate 220 is at the reference position Pa, the positioning unit 400 determines the positions of the base positioning holes 210a of the base plate 210 and the member facing plate 220 Since the holes 220a are opposed to each other, the member-facing plate 220 can be accurately positioned at the reference position Pa.

When the member facing plate 220 is in the first slide position Pb, the base positioning hole 210a of the base plate 210 and the positioning hole for the first slide position 220b are opposed to each other, the member-facing plate 220 can be accurately positioned at the first slide position Pb.

When the member facing plate 220 is at the second slide position Pc, the base positioning hole 210a of the base plate 210 and the second slide position positioning hole 220c are opposed to each other, the member-facing plate 220 can be accurately positioned at the second slide position Pc.

As a result, when any one of the suction regions Aa, Ab, and Ac is formed, the opposed relationship between the suction holes facing each other in the suction regions Aa, Ab, and Ac can be maintained. Thus, even when the suction operation is performed, a proper suction operation can be performed for a long period of time without collapsing the opposing relationship between the suction holes 221 of the member-facing plate 220 and the base suction holes 211 of the base plate 210 .

10 is a view for explaining the peeling mechanism section 500 of the film peeling apparatus. The peeling mechanism section 500 of the film peeling apparatus is constituted such that the film Wc (also referred to as a film Wc having a ground), which is peelably adhered to the ground Wm as shown in Fig. 10 A peeling portion 510 having a horizontal surface 511 supporting the lower surface of the ground Wm and an inclined surface 512 forming an acute angle? (For example,? = 45 degrees) with respect to the horizontal surface 511; A roll 530 that changes the traveling direction of the ground Wm folded at the peeling unit 510 and a roll 530 that is disposed above the peeling unit 510 along the z axis And a flat-plate-like member suction device 20 as a suction device installed vertically movably in the direction of an arrow z-z '. The plate-shaped member suction device 20 is provided such that the member-facing plate 220 is faced downward so as to face the film Wc having the ground.

A ground folding section 513 is formed at the front end of the peeling section 510 (the connecting section between the horizontal plane 511 and the slanted plane 512). Since the film Wc is peeled from the ground Wm in the forward direction (direction of the arrow x ') of the ground Wm than the ground folding unit 513, only the ground Wm advances do.

In addition, the pedestal 520 is reciprocally movable along the x-axis in the direction of the arrow x-x 'together with the peeling portion 510.
