Definitions
- the invention relates to a device for processing a foil substrate, comprising a holder for a roll of the foil substrate and a transporter unit for unwinding the rolled foil substrate and transporting it along a process path.
- Such devices can for example be plasma processing devices or chemical vapour deposition devices in a roll-to-roll process or a roll-to-sheet process, e.g., for production of flexible electronic or optical components, flexible displays or photovoltaic foils.
- WO 98/13882 discloses a method of manufacturing a photovoltaic foil.
- the process uses a temporary substrate on which flexible thin-film solar cells are deposited.
- the use of the temporary substrate allows relatively high processing temperatures while using (semi-)continuous roll-to-roll (or reel-to-reel) production processes.
- the active layers of such solar cells comprise a transparent conductive oxide layer (TCO), an active absorbent layer (e.g., thin-film silicon), and a back contact layer (e.g. a reflective metal layer).
- TCO transparent conductive oxide layer
- an active absorbent layer e.g., thin-film silicon
- a back contact layer e.g. a reflective metal layer
- the active absorber layer which can for instance be a thin film silicon layer, is deposited, e.g., using plasma enhanced CVD.
- the reflective back contact can then be deposited by means of physical vapor deposition and a pattern can be prepared for monolithic interconnection.
- the film can then be laminated to a permanent carrier foil. Wet etching techniques can be used to remove the temporary substrate foil.
- the foil can be stretched when it follows its path during the depositing process steps, e.g., with the aid of rollers positioned at regular distances of each other on the same side of the foil substrate.
- the rollers push on one of the foil surface, so that each roller deflects the process path over a certain angle. Since all rollers push on the same side, the cumulative effect is that the foil substrate follows a polygonal or curved process path, with the processing stations being directed to the convex outer surface of the foil substrate. If a large number of rollers are used, it is desirable to redirect the process path to prevent that the process path curls up too much. Redirecting could be done with the aid of a turning roller on the opposite side of the foil substrate. However, such a turning roller would act upon the surface with the freshly deposited layer, which could be damaged as a result.
- the object of the invention is achieved with a device for processing a foil substrate, comprising a holder for a roll of the foil substrate and a transporter unit for unwinding the rolled foil substrate and transporting it in a transport direction along a process path, wherein the device comprises at least one redirecting roller with an axis of rotation which is parallel to the surface of the passing foil substrate and which is not under right angles with the transport direction.
- the foil passes the redirecting roller, the foil is redirected under an angle which is dependent on the angle between the roller and the transport direction of the foil before passing the redirection roller, and which is also dependent on the angle between the roll-on direction and the tangential roll-off direction of the foil passing the roller.
- a single roller under an angle of 45 degrees with the transport direction can redirect the foil under an angle of 90 degrees if the foil is turned over 180 degrees over the circumference of the roller.
- a number of stretching members such as rollers, is configured to push upon one side of the foil substrate, the stretching members extending along the full width of the foil substrate in a direction perpendicular to the transportation direction.
- the stretching members create a polygonal process path, wherein one or more processing stations can be positioned at the convex side of the process path.
- the processing stations can for example be chemical vapour deposition stations.
- the device can for example comprise two subsequent redirecting rollers each turning the process path over a right angle. These two redirecting rollers can for example be parallel. As a result, after the foil substrate passes the two redirecting rollers the transportation direction will be the same but offset over a certain distance in comparison to the transportation direction of the foil before passing the redirecting rollers. Alternatively, the two redirecting rollers can for example be under right angles with each other.
- the device according to the present invention can also have more than two, e.g., three or four redirecting rollers, for gradually redirecting the processed foil substrate into the desired direction.
- the redirecting rollers can comprise independently moveable axial segments, which compensate for the lateral movement of the foil.
- the segments can be moved actively by a programmed driver or they can be moved passively, e.g., by a tracer following a guiding surface when the roller is turned, wherein either the tracer of the guiding surface is connected to the axial segment.
- the tracer can for example be a tracer pin or tracer wheel.
- the foil material itself may exert a force acting against the lateral movement. Depending on the type of foil material used and on further process conditions, this force exerted by the foil may be sufficient to compensate for the lateral movement.
- a suitable type of roller turner that could be useful in a device according to the present invention is a roller turner as disclosed in NL 9402031 , disclosing the use of such a roller to correct lateral movement of a conveyor belt.
- Figure 1 shows a device 1 according to the present invention for manufacturing a photovoltaic foil by depositing the various layers on a foil substrate 2 in a roll-to-roll process.
- the device 1 comprises a holder 3 for a roll of foil substrate 2 and rollers 4 for transporting the foil substrate 2 along a process path with chemical vapor deposition (CVD) stations 5.
- the foil substrate 2 runs in a direction indicated in the drawing by reference sign A, A', A", A"', A"", and A V respectively.

- the process path includes a first curved section 8, a redirecting section 9 and a second curved section 10.
- the turner rollers 4 push on the passing foil substrate 2 at regular distances. Since each roller 4 deflects the path of the foil substrate 2 over a small angle, the process path curves.

- the foil substrate is rewound to a roll 15.
- the roll 15 is operatively connected to a transporter unit 16. By winding the roll 15, the roll 3 is unwound and the foil substrate is transported in the transport direction along the process path 8, 9, 10.

Description
- The invention relates to a device for processing a foil substrate, comprising a holder for a roll of the foil substrate and a transporter unit for unwinding the rolled foil substrate and transporting it along a process path. Such devices can for example be plasma processing devices or chemical vapour deposition devices in a roll-to-roll process or a roll-to-sheet process, e.g., for production of flexible electronic or optical components, flexible displays or photovoltaic foils.

WO 98/13882 - To obtain high quality deposit layers of even thickness, the foil can be stretched when it follows its path during the depositing process steps, e.g., with the aid of rollers positioned at regular distances of each other on the same side of the foil substrate. The rollers push on one of the foil surface, so that each roller deflects the process path over a certain angle. Since all rollers push on the same side, the cumulative effect is that the foil substrate follows a polygonal or curved process path, with the processing stations being directed to the convex outer surface of the foil substrate. If a large number of rollers are used, it is desirable to redirect the process path to prevent that the process path curls up too much. Redirecting could be done with the aid of a turning roller on the opposite side of the foil substrate. However, such a turning roller would act upon the surface with the freshly deposited layer, which could be damaged as a result.
- It is an object of the invention to provide a device for layer deposition on a foil substrate in a roll-to-roll or roll-to-sheet process which can turn or redirect the unrolled substrate without contacting freshly deposited layers on the substrate.
- The object of the invention is achieved with a device for processing a foil substrate, comprising a holder for a roll of the foil substrate and a transporter unit for unwinding the rolled foil substrate and transporting it in a transport direction along a process path, wherein the device comprises at least one redirecting roller with an axis of rotation which is parallel to the surface of the passing foil substrate and which is not under right angles with the transport direction. When the foil passes the redirecting roller, the foil is redirected under an angle which is dependent on the angle between the roller and the transport direction of the foil before passing the redirection roller, and which is also dependent on the angle between the roll-on direction and the tangential roll-off direction of the foil passing the roller. For instance, a single roller under an angle of 45 degrees with the transport direction can redirect the foil under an angle of 90 degrees if the foil is turned over 180 degrees over the circumference of the roller.
- Optionally, a number of stretching members, such as rollers, is configured to push upon one side of the foil substrate, the stretching members extending along the full width of the foil substrate in a direction perpendicular to the transportation direction. This way, the stretching members create a polygonal process path, wherein one or more processing stations can be positioned at the convex side of the process path. The processing stations can for example be chemical vapour deposition stations.
- The device can for example comprise two subsequent redirecting rollers each turning the process path over a right angle. These two redirecting rollers can for example be parallel. As a result, after the foil substrate passes the two redirecting rollers the transportation direction will be the same but offset over a certain distance in comparison to the transportation direction of the foil before passing the redirecting rollers. Alternatively, the two redirecting rollers can for example be under right angles with each other.
- The device according to the present invention can also have more than two, e.g., three or four redirecting rollers, for gradually redirecting the processed foil substrate into the desired direction.
- When a foil is turned by a roller under an angle with the transport direction, the foil will tend to move laterally. To correct this, the redirecting rollers can comprise independently moveable axial segments, which compensate for the lateral movement of the foil. The segments can be moved actively by a programmed driver or they can be moved passively, e.g., by a tracer following a guiding surface when the roller is turned, wherein either the tracer of the guiding surface is connected to the axial segment. The tracer can for example be a tracer pin or tracer wheel. Also the foil material itself may exert a force acting against the lateral movement. Depending on the type of foil material used and on further process conditions, this force exerted by the foil may be sufficient to compensate for the lateral movement.
- A suitable type of roller turner that could be useful in a device according to the present invention is a roller turner as disclosed in
NL 9402031 - The invention will now be described in more detail, by way of example only, with reference to the accompanying drawing, wherein:
- Figure 1:

Figure 2 or3 . -
Figure 1 shows a device 1 according to the present invention for manufacturing a photovoltaic foil by depositing the various layers on afoil substrate 2 in a roll-to-roll process. The device 1 comprises aholder 3 for a roll offoil substrate 2 and rollers 4 for transporting thefoil substrate 2 along a process path with chemical vapor deposition (CVD)stations 5. Thefoil substrate 2 runs in a direction indicated in the drawing by reference sign A, A', A", A"', A"", and AV respectively. TheCVD stations 5 deposit a layer onto a deposition side 6 of thefoil substrate 2 opposite the side 7 contacted by the rollers 4. - The process path includes a first
curved section 8, a redirecting section 9 and a secondcurved section 10. In order to obtain a uniformly tensioned foil the turner rollers 4 push on the passingfoil substrate 2 at regular distances. Since each roller 4 deflects the path of thefoil substrate 2 over a small angle, the process path curves. After passing a number of rollers 4 in the first curvedprocess path section 8 thefoil substrate 2 runs in an almost vertical direction A' to a final roller 11 turning thefoil substrate 2 over more than 90 degrees to a horizontal direction A". Subsequently, thefoil substrate 2 runs to a first redirectingroller 12. The axis of rotation of the redirectingroller 12 and of the final roller 11 are within the same plane making an angle of 45 degrees with each other. - The
foil substrate 2 runs over 180 degrees over the circumference of the redirectingroller 12. Due to the fact that the redirectingroller 12 is positioned under an angle of 45 degrees with the roll-on direction A" of thefoil substrate 2, thefoil substrate 12 is redirected to a horizontal roll-off direction A"' under right angles with the horizontal roll-on direction A" of thefoil substrate 2. Subsequently thefoil substrate 2 passes a second redirectingroller 13, which is parallel to and in the same plane as the first redirectingroller 12. Again, thefoil substrate 2 passes the circumference of the second redirectingroller 13 over 180 degrees and is again redirected over 90 degrees to a horizontal direction A"" parallel to the direction A" of the foil between the final roller 11 and the first redirectingroller 12. Subsequently, thefoil substrate 2 passes a first roller 14 of the second curvedprocess path section 10. This way, the upwards direction A' of thesubstrate foil 2 is turned to a downwards direction AV without using a turner roller contacting the freshly processed lower surface 6 of thefoil substrate 2. - At the end of the second curved
process path section 10, the foil substrate is rewound to a roll 15. The roll 15 is operatively connected to atransporter unit 16. By winding the roll 15, theroll 3 is unwound and the foil substrate is transported in the transport direction along theprocess path -
Figure 2 shows a set of twoparallel redirection rollers 20, 21. A foil 22 is transported in a direction indicated with arrow B. The first roller 20 is under an angle of about 45 degrees with the transport direction B. The foil 22 passes the roller 20 over 180 degrees relative to the longitudinal axis of the roller 20 over the circumference of the roller 20. As a result, the foil substrate 22 is redirected over an angle of 90 degrees in plan view to a roll-off direction B'. After passing the first redirecting roller 20, the foil 22 passes thesecond redirection roller 21 which is substantially parallel to the first redirection roller 20. Again, the foil 22 passes thesecond redirection roller 21 over 180 degrees relative to the longitudinal axis of thesecond roller 21 of its circumference, resulting in a redirection of again 90 degrees in plan view, and a new curved process path, parallel to the first process path can be followed with a transport direction B", which is in plan view the same as the transport direction B of the first flow path. - An alternative arrangement can be seen in
Figure 3 where tworedirection rollers 30, 31 are arranged under right angles with each other. With such an arrangement, the resulting transport direction C" is opposite to the first transport direction C. - The
redirection rollers axial surface segments 32 which can be moved independently in the axial direction relative to the rest of theredirection roller redirection roller roller -
Figure 4 shows aroller 34 corresponding to therollers tracer mechanism 35. Thetracer mechanism 35 comprises a guidingsurface 36 extending radially from the circumference of theroller 34. The guidingsurface 36 comprises a firstrounded turning point 37 and a secondrounded turning point 38 which is at a distance from thefirst turning point 37 viewed in the longitudinal direction of theroller 34. Between the tworounded turning points surface 36 runs smoothly and uninterrupted. - The
roller 34 is provided with four axially moveable segments 40, only one of which is shown in the drawing ofFigure 4 for reasons of clarity. The axially moveable segment 40 comprises an outer shell 41 shaped as a quarter of a cylinder and having a concave inner surface with a slider head 42 in the middle of the concave surface extending in a direction parallel to the longitudinal axis of theroller 34. The slider head 42 is arranged on a guidingrail 43 on the cylindrical surface of a cylindrical core 44 of theroller 34. The guidingrail 43 extends into a direction parallel to the longitudinal axis of theroller 34. The slider head 42 is slideable over the guidingrail 43. - A
stationary bus 45 fits over one end of the cylindrical core 44 of theroller 34. Thebus 45 does not rotate with the cylindrical core 44. To minimize friction between thebus 45 and the core 44, sufficient play between the two parts should be provided. Thestationary bus 45 is made of a single part with the guidingsurface 36. - The axially moveable segment 40 has a tapered
end 46 directed to the guidingsurface 36. Thetapered end 46 carries a shoe 47 with a tracer wheel 48 contacting the guidingsurface 36. When theroller 34 with the axial segments 40 rotates, the tracer wheel 48 moves along thestationary guiding surface 36. When the tracer wheel 48 moves to the firstrounded turning point 37, the guidingsurface 36 pushes the axial segment 40 away towards the other end of theroller 34. When afoil substrate 2 runs over theroller 34 in a direction which is not under right angles with theroller 34, thefoil substrate 2 will tend to move towards the guidingsurface 36. The guidingsurface 36 is arranged in such a way that the secondrounded turning point 38 is in line with the first roll-on contact line of the foil substrate with theroller 34. When theroller 34 is rotated, the axial segment 40 is pushed away against the lateral movement of thefoil substrate 2 until the tracer wheel 48 reaches the firstrounded turning point 37. Thispoint 37 is in line with the last roll-off contact line between thefoil substrate 2 and theroller 34, where the foil substrate departs from theroller 34. Subsequently, the axial segment is allowed to slide back towards the secondrounded turning point 38 of the guidingsurface 36, e.g., under the action of a spring or the like.
