Summary of the invention
But, exist the problem points that between the otpical leaf of lamination, produces foreign matter in the method that patent documentation 1,2 is disclosed.
Particularly, in the method that patent documentation 1,2 is disclosed,, must the periphery of otpical leaf laminated body be carried out like above-mentioned joint for the otpical leaf of lamination is done as a whole the processing.
When use roller to as above-mentioned joint after the surface of otpical leaf laminated body when cleaning; The laminated body thin slice on surface can receive stress; Yet because inboard thin slice engages through circumference with the thin slice on surface, therefore the displacement of the thin slice of inboard can be suppressed.Therefore, the mutual friction of two thin slice phases causes foreign matters such as between two thin slices, producing the thin slice chip.In addition, two thin slices are distorted relatively, might destroy the flatness of otpical leaf laminated body.Especially near engaging zones, possibly can't obtain desired optical characteristics.
When the laminated body with otpical leaf cut into the shape of regulation, the foreign matter that takes place in cut-out portion can be attached to surface, the back side and the side of otpical leaf laminated body.In the method that patent documentation 2 is disclosed; Cutting sheet is become the shape of regulation and its circumference engaged the otpical leaf laminated body that forms through cleaning device the time; Because having been accomplished the laminated body of punching around it surrounds; Therefore, though can clean its surface and the back side, be difficult to its side is cleaned.In addition, about cutting into the otpical leaf laminated body of regulation shape, surrounding around it only is the laminated body of having accomplished punching; And there is not other restraining force; Therefore, when the pressure that receives from clearing apparatus, may leave original position and move freely.Therefore, the otpical leaf laminated body that is difficult to make cut-out perhaps is difficult to correctly be transported to subsequent processing correctly through cleaning device.
The present invention develops in view of the above problems, and its purpose is to be provided for cleaning the surface and the back side of stack of sheets body and can being suppressed at clearing apparatus and the cleaning method that produces foreign matter between the thin slice.
In order to address the above problem, the clearing apparatus of stack of sheets body of the present invention is used to clean the surface and the back side of the stack of sheets body that is formed by a plurality of stack of sheets, it is characterized in that comprising: cleaning part, clean the foreign matter at the surface and the back side of above-mentioned stack of sheets body; Hold assembly is at the above-mentioned stack of sheets body of single place's clamping; Air-flow formation portion, with the clamping face almost parallel direction of the stack of sheets body of above-mentioned hold assembly clamping on, form air-flow along the surface and the back side of stack of sheets body.
According to foregoing invention, the two keeps the stack of sheets body to form portion by hold assembly that carries out single place's clamping and air-flow.Therefore; When cleaning; Even there is stress to be applied on the surface and the back side of stack of sheets body; Also the thin slice because of side within the thin slice at the surface and the back side and the surface and the back side only receives clamping on the clamping face of hold assembly clamping, and other parts do not receive clamping, thereby is difficult for rubbing between two thin slices.In addition, owing to surface and the back side formation air-flow of air-flow formation portion along the stack of sheets body, therefore, surface and these 2 thin slices of the back side receive the stress to its inboard thin slice.Thus, can suppress the thin slice of the thin slice separated from its internal side at the surface and the back side, keep the whole stable state of stack of sheets body.Therefore, the stack of sheets body is maintained at extremely and is fit to the state that cleaned by cleaning part, and the foreign matter that produces of the friction because of between the thin slice can reduce the cleaning part cleaning time, and can suppress the unbalanced of cleaning performance.
In order to address the above problem; The cleaning method of stack of sheets body of the present invention is used to clean the surface and the back side of the stack of sheets body that is formed by a plurality of stack of sheets; It is characterized in that: at the above-mentioned stack of sheets body of single place's clamping; And with the direction of the clamping face almost parallel of the stack of sheets body that is held on, form air-flow along the surface and the back side of stack of sheets body, thereby keep the stack of sheets body.

The specific embodiment
Below, referring to figs. 1 through Fig. 6, an embodiment of the invention are described.Fig. 1 observes 10 o'clock profile of clearing apparatus of the present invention (clearing apparatus of stack of sheets body) from directions X.Clearing apparatus 10 is symmetric shape on X-direction.
Clearing apparatus 10 possesses upside hold assembly (hold assembly) 2a and downside hold assembly (hold assembly) 2b that are used for clamping fine sheet (stack of sheets body) 1, be used to clean upside cleaning part (cleaning part) 3a and downside cleaning part (cleaning part) 3b of fine sheet 1 and be used for forming air-flow and possessing the attraction head (air-flow generation portion) 5 that attracts peristome 4 along fine sheet 1.
Fine sheet 1 is the object that clearing apparatus 10 cleans.To be positioned at surface and the back side of fine sheet 1 outermost sheet plane as fine sheet 1.Fine sheet 1 is formed by a plurality of stack of sheets, and fine sheet 1 has 3-tier architecture.But, be not limited thereto, have the structure that constitutes by a plurality of thin slices and get final product.For example, can constitute by 2～20 thin slices.
Constitute fine sheet 1 thin slice so long as laminar just can, this is not had special qualification.For example, can use optical thin films such as polarizing coating, lens, diffusion sheet, prismatic lens; Macromolecule membranes such as PET film (pet film), polyurethane film; And paper wood etc.
Wherein, if fine sheet 1 is the otpical leaf that includes optical thin film, the bad phenomenon such as bright spot due to the foreign matter appear easily just on the otpical leaf.Therefore, for the clearing apparatus of the present invention 10 that can appropriately remove foreign matter, this fine sheet 1 is more suitable cleaning object.Through using clearing apparatus 10 to clean otpical leaf, can come effectively to remove foreign matters such as thin slice particle, dust with higher cleaning performance, therefore can improve the productivity and the yield rate of otpical leaf.
Upside hold assembly 2a and downside hold assembly 2b (below, claim that also these two parts are " hold assembly 2 ") be the parts that are used to support fine sheet 1, by upside hold assembly 2a and downside hold assembly 2b fine sheet 1 is carried out the clamping of list place.So-called list is located clamping, and is as shown in the figure, clamping fine sheet 1 in a place.But, not with the scope of contradiction of the present invention in, also can possess a plurality of hold assemblies 2.In addition, also can use the parts of controlling that fine sheet 1 is controlled to replace hold assembly 2.
Because fine sheet 1 is held parts 2 and attracts 5 maintenances; Therefore, as preferably, on the position beyond the center of gravity of fine sheet 1, keep by hold assembly 2; Particularly, on the position beyond the center of gravity at least fine sheet 1, on the Y direction, keep.About this position, for example be the end of fine sheet 1 shown in Figure 1.
Upside cleaning part 3a and downside cleaning part 3b (below, claim that also these two parts are for " cleaning part 3 ") clamping fine sheet 1, and be located at the both sides on the thickness direction (Z direction) of fine sheet 1.In the figure, cleaning part 3 is adhesive roller.As stated, cleaning part 3 can be the parts that utilize adherence to clean, still, as long as just can remove fine sheet 1 surface and the back side foreign matter can, the indefinite not to this.For example, can adopt the air that can attract air and foreign matter simultaneously to attract structure, perhaps adopt the structure of cleaning with electrostatic attraction.When adopting the structure that air attracts, must guarantee to attract 5 attraction not interrupted.Particularly, when adopting air to attract structure, the attraction head is for example arranged; When adopting the electrostatic attraction structure, electronegative charged roller is for example arranged.
Approaching each other can on the displacement direction Z that predesignates, carrying out perhaps away from the mode of displacement, hold assembly 2 and cleaning part 3 are set respectively.In addition, with the mode that can on the displacement direction Y that predesignates, carry out displacement cleaning part 3 is set.
About the action of clearing apparatus 10, at first, hold assembly 2 is to locate the surface and the back side of the mode clamping fine sheet 1 of clamping at list.Under this state, because just at single place's clamping fine sheet 1, so film is hang.Then, be at clamping face on the direction of almost parallel, that is, be on the direction of almost parallel, by attracting 5 a surface and a back side to form air-flow along fine sheet 1 with the surface of hold assembly 2 and fine sheet 1 and the face of joint, the back side with the fine sheet that is held 1.
Thus, the attraction that utilizes single place's clamping of hold assembly 2 and attract 5 keeps fine sheet 1.Attract 5 to be not one-sided at fine sheet 1 only, but form air-flow with the both sides at the back side surfacewise, therefore, 2 thin slices at the surface of fine sheet 1 and the back side receive the stress to its inboard thin slice.Therefore, can suppress the thin slice of the thin slice separated from its internal side at the surface and the back side, thereby keep the stable state of fine sheet 1 integral body.
Then, clean by the surface and the back side of 3 pairs of maintained fine sheets 1 of cleaning part.When keeping fine sheet 1, make itself and above-mentioned clamping face almost parallel.At this, almost parallel is meant, fine sheet 1 as long as fine sheet 1 is kept in this state, just can be realized effect of the present invention being the state of almost parallel from clamping face towards a direction that attracts 5.Certainly, fine sheet 1 also can be parastate with respect to clamping face.
When cleaning; Even the stress due to the cleaning part 3 is applied on the surface and the back side of fine sheet 1,, and do not receive clamping in other parts because the inboard thin slice in the thin slice at the surface and the back side and surface and the back side only receives clamping on the clamping face of hold assembly 2 clampings; Therefore; Distortion due to the stress can't concentrate on the surface and the back side, but is scatter, so be difficult for rubbing between two thin slices.Therefore, fine sheet 1 is maintained at extremely be fit to the state that cleans by cleaning part 3, and the foreign matter that produces of the friction because of between the thin slice can reduce cleaning part 3 cleanings the time, and can suppress the unbalanced of cleaning performance.
In addition, when fine sheet 1 is an otpical leaf, and on each thin slice that constitutes fine sheet 1, is formed with coating, when concavo-convex etc., is easy to generate foreign matter because of friction takes place between the thin slice.Also can use clearing apparatus 10 to clean for this type of otpical leaf, so this device is very superior.
About the action of clearing apparatus 10, preferred cleaning part 3 is from the central part of the fine sheet 1 that is maintained at the almost parallel state, moves towards the end of fine sheet 1, opposite with hold assembly 2 side.Thus, because cleaning part 3 does not move to the direction of hold assembly 2, therefore, even the stress due to the cleaning part 3 is applied on the fine sheet 1, the distortion that also can suppress due to pressure causes fine sheet 1 to bend.In addition and since cleaning part 3 towards the end direction of hold assembly 2 promptly, attract a direction of 5 to move, so this action can assist the support thin slice, so even under the less situation of air-flow formation amount, also can maintain fine sheet 1.
Fig. 2 is illustrated on the Y direction to observe to attract a profile of 5 o'clock.State when (a) of Fig. 2 represented only to come clamping fine sheet 1 by hold assembly 2, warpage or sagging takes place in fine sheet 1 on Z-direction.Can be observed, on X-direction, away from the clamping face of hold assembly 2, warpage or sagging degree are just big more.In addition, too, away from the clamping face of hold assembly 2, warpage on Z-direction or degree of sag are also big more on Y direction.
(b) of Fig. 2 represented to possess has the clearing apparatus 10a that attracts a 5a, and the shape of this attraction 5a is different from the attraction 5 of clearing apparatus 10.In this structure, attract peristome 4 with respect to the height of fine sheet 1 width thickness greater than fine sheet 1.Through said structure, be convenient to produce air-flow at the surface and the back side of fine sheet 1, fine sheet 1 is held the state that is almost parallel through the stress of air-flow, so this structure is preferred.In this structure, the width on the X-direction of attraction peristome 4 is width L1, and it is less than the width of fine sheet 1.
Comparatively speaking, in the clearing apparatus 10 shown in (c) of Fig. 2, attracting the height H of peristome 4 identical with clearing apparatus 10a, is the width L2 also bigger than the width of stack of sheets body but attract peristome with respect to the width of the width of fine sheet 1.Through this structure, also can generate sufficient air-flow for fine sheet 1 integral width, therefore, can suppress fine sheet 1 warpage or sagging takes place on width, can make fine sheet 1 keep more parallel state with respect to clamping face.That is, can make fine sheet 1 keep more parallel state, rub between the film in the time of therefore can alleviating cleaning.Its result, thin slice damage and foreign matter that can suppress rubs is caused, and can improve cleaning performance.
Next, further the action of clearing apparatus 10 and the cleaning method of stack of sheets body of the present invention are described.In the cleaning method of stack of sheets body of the present invention, the surface and the back side that maintain the stack of sheets body that is formed by a plurality of stack of sheets are cleaned.In the method, come the above-mentioned stack of sheets body of clamping with the mode of single place's clamping, and be on the direction of almost parallel,, thereby keep the stack of sheets body along the surface and the back side formation air-flow of stack of sheets body at clamping face with the stack of sheets body that is held.Certainly, about the action of clearing apparatus 10, also can use above-mentioned cleaning method.
Fig. 3 is the profile of the cleaning action of expression clearing apparatus 10 of the present invention on directions X.Shown in Fig. 3 (a), about receiving the fine sheet 1 of single place's clamping, away from the clamping face that carries out clamping by hold assembly 2, warpage on Z-direction or sagging degree are just big more on Y direction.
Shown in Fig. 3 (b); When possess attraction 5 Y directions (flow direction) center that attracts peristome 4 with this fine sheet 1 near fine sheet 1 be benchmark, during with the tip of hold assembly 2 opposition sides; Fine sheet 1 floats over by attracting in 5 air-flows that form, thereby its shape is able to rectification.At this moment, attract 5 to carry out parallel shifted along a following straight line, this straight line is meant: be almost parallel with clamping face, be preferably parallel, and the center on directions X through fine sheet 1, and along Y direction and the straight line vertical with the X axle.
In addition; Shown in Fig. 3 (c); Through attracting to remain the form of fine sheet 1 plane; Clip fine sheet 1 by upside cleaning part 3a and downside cleaning part 3b then and sweep, thereby come the surface and the back side of fine sheet 1 are cleaned towards the end of a side opposite with hold assembly 2.Attract 5 continue attract action, until the end of sweeping of cleaning part 3.
Fig. 4 is the profile of clearing apparatus 10.This figure is used to explain under the attraction state action the when side of fine sheet 1 cleaned, and this figure is the profile at directions X.The height of the attraction peristome 4 of clearing apparatus 10 and width all thickness and the width than fine sheet 1 are big, therefore can hold fine sheet 1.
By attract 5 forms air-flow after, through the first end parts of fine sheet 1 is held into attraction peristome 4, attraction 5 can also dual-purpose be foreign matter attraction portion.That is,, can remove this superior effect again attached to the foreign matter of side except forming air-flow, also have the foreign matter that adheres on the surface that to remove fine sheet 1 and the back side.At this, after cleaning part 3 finishes cleaning, attract 5 also to can be used as foreign matter attraction portion.
Till the cleaning that preferably fine sheet 1 is retained to fine sheet 1 finishes.Thus, owing to can make the stack of sheets body keep shakedown, till cleaning release, therefore can further alleviate because of the problem that friction causes damaging and producing foreign matter takes place between the thin slice.In addition, before hold assembly 2 clamping sheet materials 1, as preceding operation; Preferably a plurality of cutting sheets are become shape of product, that is, the shape (size) that cuts into fine sheet 1 afterwards; Through a plurality of thin slices that cut off are carried out lamination, obtain fine sheet 1, then above-mentioned stack of sheets body is carried out clamping.Thus, obtain rapidly fine sheet 1 to be kept and to clean after the fine sheet 1, therefore can further alleviate foreign matter attached to the problem on the stack of sheets body.
Fig. 5 be used to explain by cleaning part 3 promptly, always existing bad problem when adhesive roller is cleaned surface and the back side of fine sheet 1, this figure is the profile in X-direction.In order to compare, in cleaning action shown in Figure 5, do not use to attract 5 to clean fine sheet 1 with the present invention.
Shown in Fig. 5 (a), on the fine sheet 1 that receives single place's clamping, away from clamping face, warpage on the Z direction or degree of sag are just big more on the Y direction.As cleaning part 3, preferably use the adhesive roller that cleaning performance is high and can clean continuously.In the case, need on the thickness direction of fine sheet 1, clamp cleaning part 3 from both sides.Shown in Fig. 5 (b), fine sheet 1 is not to be plane, but because of sagging and crooked, therefore, uses cleaning part 3 to come before the clamping fine sheet 1, and fine sheet 1 just might come in contact with downside cleaning part 3b.If post up at fine sheet 1 under the state of downside cleaning part 3b, continue by cleaning part 3 clamping fine sheets 1, shown in Fig. 5 (c), fine sheet 1 just may bend so, and is therefore unsuitable.
Fig. 6 be used to explain by cleaning part 3 promptly, always existing bad problem when adhesive roller is cleaned surface and the back side of fine sheet 1, this figure is the profile in X-direction.Shown in Fig. 6 (a), in order to solve bad problem shown in Figure 5, used upside cleaning part 3c and the downside cleaning part 3d that the adhesive roller of dwindling cleaning part 3 directly forms.Shown in Fig. 6 (b), when adopting said structure,, therefore problem as shown in Figure 5 can not take place, and when clamping fine sheet 1, warpage can not take place in fine sheet 1 because viscosity roller footpath is less.At this moment, between each thin slice of fine sheet 1 magnitude of misalignment δ 1 can take place.
Shown in Fig. 6 (c), along with two cleaning parts move and clean to the end of fine sheet 1, that kind shown in magnitude of misalignment δ 2 of the dislocation between each thin slice diminishes.When two cleaning parts moved to the end of fine sheet 1, dislocation just disappeared.But, during this section that dislocation is corrected,, may cause foreign matters such as thin slice damage or generation thin slice chip because of rubbing between each thin slice.
Like Fig. 5 and shown in Figure 6, under the situation that does not adopt attraction of the present invention 5, can know can take place between each thin slice of fine sheet 1 bad.With respect to this, as use the clearing apparatus 10 of this embodiment, then can not take place above-mentioned badly, therefore can carry out high performance cleaning fine sheet 1.
The present invention is not limited to above-mentioned embodiment, can carry out all changes within the scope of the claims, also belongs in the technological category of the present invention through the technology that different embodiment disclosed being made up the embodiment that obtains.
