Definitions
- This present invention relates to a device and a method for processing a useful surface of large-area substrates, in particular those with a length or width of> 0.5 m and a thickness ⁇ 1 cm, with at least three spaced-apart storage facilities for receiving a substrate and a movable processing device for processing the useful surface of the substrate between the storage facilities.
- a processing of the useful side arranged on the upper side is advantageous because then the substrate can be placed horizontally on a substrate and then from above by means of a suitable processing device, for example a laser beam in X and Y direction on the entire usable area can be processed.
- a processing from the glass back side can be more advantageous.
- the processing of the coated payload side of the glass substrate is performed by a laser beam from the uncoated glass substrate backside.
- the substrate if it is horizontally mounted on the substrate edge and an interesting for commercial use size (length, or width> 0.5 m, thickness ⁇ 1 cm) by the weight bends considerably. Deflection makes machining more difficult because the distance between the processing device and the substrate, such as the laser optics lens and the glass bottom, should not change for precise machining.
- solutions according to FIG. 1 are currently in use, which for the substrate 11 have a support table 13 with a narrow gap 15 in the middle of the table, which extends at right angles to the substrate movement.
- the gap 13 is one or more displaceable processing means are arranged, whereby a processing in the X direction according to Arrow 19 is made possible from the substrate rear side by moving the processing device and in the Y direction by moving the substrate and thus the entire useful surface can be processed.
- the support table 13 has for the movement of the substrate 11 to a storage, which usually consists of an air bearing or a conveyor belt.
- a device for producing a thin-film solar cell with which a substrate, in order to spread it as flat as possible, is held along the edges in a planar alignment and is supported in the surface selectively by support structures. These support structures are positioned at locations that are not machined. The processing of the thin film is carried out by laser from the top and the thin film is on the supported bottom.
- a device for processing thin-film solar cells is known.
- a transparent support is provided, through which the thin film present on the upper side of the substrate is processed from the underside with a laser beam.
- Air channels are formed in the support, which allow the substrate to be sucked onto the support and thereby fixed in position.
- this is provided with recesses through which the coating of the substrate is processed.
- the pad can be made in this case of a non-transparent material.
- FIGS. 1 and 2 a single line structure is produced with the laser beam only between the air ducts, so that the recesses in the non-transparent recesses only have to provide space for a single line structure.
- This device has the disadvantage that the transparent glass plate is very thick, especially in large-area substrates. It is also disadvantageous if, for large substrates (length or width> 1 m), non-transparent bearings are used, that a considerable part of the substrate useful surface is not accessible for processing and only individual laser lines can be drawn between the bearing devices. task
- the invention provides the task of providing a cost-effective, efficient solution for the back-side processing of large-area substrates.
- the device for the processing of large-area substrates from the substrate back has forth in a known manner more than two spaced-apart storage facilities for receiving a substrate and a movable processing means for processing the substrate between the storage facilities from the substrate rear side.
- a movable processing means for processing the substrate between the storage facilities from the substrate rear side.
- a displacement device is now provided in the device in order to achieve a relative displacement between at least the non-terminal bearing devices and the substrate. It is thereby achieved that the areas stressed before the displacement of the storage facilities are accessible for processing after the displacement.
- the claimed by the bearing devices areas are only accessible thanks to the relative displacement for processing from the back, since the areas to be machined may not be covered during the laser processing on the coated Nutzseite.
- These four embodiments are particularly easy to implement when only non-marginal storage facilities are displaced.
- the storage devices can be arranged under the substrate, so that the substrate is pressed by gravity onto the bearing device. If the storage facilities are designed in the manner of suction bars according to JP 06-326337, they can be arranged both below and above the substrate and hold the substrate by the pressure prevailing in the suction, negative pressure, optionally against gravity.
- a plurality of intermediate regions can be processed between the bearing devices and, after a relative displacement between at least one non-terminal bearing device and the substrate, also be processed by the at least one bearing device hidden area of the useful surface before this shift. This usually only a shift is necessary if several shifts could be made.
- the useful side is expediently arranged overhead and the processing takes place from below through the substrate.
- the entire substrate surface is machineable and accessible to the processing device by moving the displaceable bearing device made.
- the machining accuracy increases because the substrate rests during the machining process with respect to the marginal storage facilities.
- a device for moving the displaceable or movable storage devices is advantageously provided.
- a horizontal displacement of the bearing device can be done for example by means of a linear motor.
- a vertical movement of the bearing device can be provided before and after the displacement of the bearing device.
- the processing device is movable in the transport direction of the substrate and transversely thereto (X and Y direction), so that processing from the substrate rear side in the respective accessible areas between the movable storage facilities is possible.
- the processing device in the transport direction of the substrate (if there is one) and transversely to (X and Y direction) movable. Thanks to the two mutually perpendicular directions of movement processing from the back of the substrate is possible in the entire accessible areas between the bearings.
- the processing device is equipped in a preferred embodiment with one or more laser sources, so that the substrate can be processed simultaneously with one or more laser beams.
- the movements of the processing device and the movable storage elements may be mechanically coupled.
- the device has a rotator which can be guided to the substrate to grip it and around the center of the useful side or the back of the substrate, ie in the region of its center of gravity, by +/- 90 ° about an axis perpendicular to to turn its effective area.
- the turning device can be below be arranged of the substrate or are also above the substrate. It can additionally be designed as a transport device and serve for transporting the substrate from the loading position into the processing station and further into the unloading position by additionally being equipped with a linear drive.
- the rotator is disposed on the back side of the substrate, which is usually below the substrate, a vacuum suction method for attaching the substrate to the rotator to perform the rotary or sliding movement is advantageous. If the rotating device holds the substrate on the useful side, in particular above the substrate, a combination of suction / air bearing or a bemoulling can be used in order to avoid contact with the risk of injury to the usable surface. Alternatively, the rotator may clamp the substrate at the ends to provide non-contact with the payload side of the substrate.
- the storage of the substrate on the back has the advantage that the user side for monitoring, further processing, suction of ablated material, etc. is free over the entire surface of obstructing storage facilities.
- the subject matter of the present invention is also a method for processing a useful surface which expands on the useful side of a substrate, in which method the substrate is fixed in a fixed position in three or more storage devices during a processing process and is removed from the substrate rear side opposite the useful surface by means of a processing device, e.g. a laser source is processed through the substrate and optionally at the same time on the Nutzseite the processing zone is accessible for example monitoring or aspiration of the ablated material.
- a processing device e.g. a laser source
- the substrate is fixed in a fixed position in three or more storage devices during a processing process and is removed from the substrate rear side opposite the useful surface by means of a processing device, e.g. a laser source is processed through the substrate and optionally at the same time on the Nutzseite the processing zone is accessible for example monitoring or aspiration of the ablated material.
- a method for processing a substrate is advantageous, in which method the substrate is deposited on storage devices and processed from below by means of a processing device, eg a laser source, which is characterized in that the substrate is deposited on three or more spaced-apart storage devices and during the machining process can rest on the bearings in a stable position, and that, for machining the area covered by the bearings, the position of the substrate relative to the bearing is displaced by at least the width of the bearings, but preferably at a maximum by a distance of the bearing from each other corresponding way, so then the not yet processed usable area can be edited.
- a processing device eg a laser source
- the method is characterized in a preferred embodiment in that the substrate remains in a fixed position and the storage facilities are moved to make accessible the previously covered areas of the floor space.
- the storage facilities can remain in a fixed position, and the substrate can be moved to make accessible the previously covered areas of the floor space.
- both the storage facilities and the substrate can be moved to make accessible the previously covered areas of the floor space.
- the processing device for processing the substrate is advantageously moved in two intersecting directions (X and Y direction).
- the processing device is also adjustable in height (distance from the substrate) in order, for example, to be able to change from one intermediate storage area to the next for the subsequent processing.
- further processing and / or control steps are advantageously carried out for processing or checking the usable area. Since the substrate rests with its rear side on storage devices during these steps, these further steps can be carried out unhindered from the useful side.
- These processing and Kontrollschirtte include, for example, the suction of ablated material, the quality control, the coating of usable space, etc.

- These bearings may be, for example, simple pads, air bearings, suction pads, conveyor belts, or a combination thereof.
- the distance between the bearing devices is chosen so that the sag of the substrate is minimal ( ⁇ 1 mm for laser structuring) and therefore the accuracy of the processing from the back side is affected as little as possible.
