Description

[0001] Method and device for producing solar modules

[0002] The invention relates to a method and a device for producing solar modules.

[0003] Such methods and devices are already known from practice. Photovoltaic cells are assembled into rows, and solar modules are constructed from electrically connected rows.

[0004] The object of the invention is to provide a method for producing solar modules and a corresponding device which promote the efficient production of solar modules.

[0005] To solve this problem, a method is initially proposed with the means and features of the first independent claim directed to a method for producing solar modules. In particular, to solve this problem, the method mentioned at the outset proposes that at least two rows be constructed and that the at least two rows be fed together to a solar module assembly.

[0006] By feeding at least two or more rows together, in particular simultaneously, the solar module can be assembled in a shorter time, thus promoting more efficient production of solar modules.

[0007] The at least two rows can be fed together to the solar module assembly by means of a motorized transfer unit, for example, a tray and / or a vacuum table and / or a belt conveyor. The use of a motorized transfer unit can facilitate the largely or even fully automated production of solar modules.

[0008] In order to equip the solar module with the rows without changing the arrangement of the photovoltaic cells in the rows created during the construction of the rows, it is advantageous if a relative alignment of the photovoltaic cells within a row and / or within two different rows is maintained during feeding.

[0009] In the finished solar module, a different electrical voltage level can be present within each individual row of photovoltaic cells. Therefore, no electrical voltage buildup occurs across the photovoltaic cells in a row in the longitudinal direction of the rows. In the finished solar module, an electrical voltage buildup can occur across the electrically connected rows and thus transversely or perpendicularly to the longitudinal direction of the rows.

[0010] According to this method, the photovoltaic cells can be assembled into rows, with an electrical voltage level being present within each individual row of photovoltaic cells. The solar modules can then be constructed from electrically interconnected rows, with an electrical voltage buildup in the solar module occurring across the electrically interconnected rows and thus transversely or perpendicularly to a longitudinal direction of the rows.

[0011] In the sense of the claimed invention, a row can thus be distinguished from a conventional string of photovoltaic cells. In a string, the

[0012] Photovoltaic cells are electrically connected to one another in such a way that an electrical voltage builds up in the longitudinal direction of the string across the electrically connected photovoltaic cells of the string.

[0013] For the electrical connection of photovoltaic cells within a row and / or photovoltaic cells of different, particularly adjacent, rows, an electrically conductive adhesive can be applied to the photovoltaic cells.

[0014] To prevent an adhesive bead from tearing off when applying the electrically conductive adhesive to a row of photovoltaic cells, it may be advantageous to match the number of jointly fed rows to the application speed of an electrically conductive adhesive. Particularly when photovoltaic cells are arranged in at least two rows using a transfer unit, the maximum feed or transfer speed at which the rows are jointly fed to the solar module assembly may be limited by the cycle time of the transfer unit during the arrangement of the photovoltaic cells.

[0015] The higher the number of jointly fed rows, the lower the feed or transfer speed at which the at least two rows of the assembly can be fed. If the electrically conductive adhesive is to be applied during the feeding of the at least two rows of photovoltaic cells for assembly of the solar module, for example by a relative movement of the rows during their feeding for assembly of the solar module to a dispensing unit with which the adhesive is dispensed, it can thus be expedient to coordinate a number of jointly fed rows with the application speed of the electrically conductive adhesive in order to ensure process reliability during the application of the electrically conductive adhesive. If the application speed of the electrically conductive adhesive is itself variable, the

[0016] The application speed of the electrically conductive adhesive must be adjusted to a number of lines fed together.

[0017] In one embodiment of the method, it is provided that a first group of jointly fed rows is fed in a first cycle section at a first vertical distance from a dispensing unit for electrically conductive adhesive and a second group of jointly fed rows is then fed at a second vertical distance from the dispensing unit, different from the first vertical distance. In this embodiment of the method, two transfer planes can thus be present, in which different groups of jointly fed rows are fed to the assembly of solar modules. These transfer planes can be arranged vertically one above the other, so that the transfer planes have different vertical distances from a dispensing point, for example a dispensing unit, for electrically conductive adhesive to the jointly fed rows.

[0018] To facilitate the connection of adjacent rows, electrically conductive adhesive can be applied to a row of photovoltaic cells with a lateral offset from the longitudinal center axis. This allows two adjacent rows to be bonded together in an overlapping manner.

[0019] To achieve this objective, a method for producing solar modules of the type mentioned at the outset is further proposed, which has the features of the second independent claim directed to such a method. To achieve this objective, it is thus proposed, in particular, that offset pieces be used in the construction of the rows to create an offset between adjacent rows.

[0020] The offset of adjacent rows from each other can be advantageous in order to create a mechanically secure and stable connection between adjacent rows within a solar module.

[0021] The use of relatively offset rows of photovoltaic cells in a solar module offers the possibility of electrically connecting a photovoltaic cell in a row with several photovoltaic cells of the same and / or neighboring rows surrounding the photovoltaic cell on the solar module. This can result in a solar module constructed in this way achieving high performance even when one or more of the solar module's photovoltaic cells are shaded.

[0022] If the offset of adjacent rows to each other is already created before the solar module is assembled when the rows of photovoltaic cells are constructed, handling of the rows when the solar module is assembled can be considerably simplified.

[0023] This can significantly increase the efficiency of the process in the production of solar modules

[0024] At this point, it should be mentioned that the use of such offset pieces may also be useful in the above-mentioned method, which is characterized by the features of the first independent claim 1.

[0025] For example, photovoltaic cells that are shorter in length and / or have a different geometry than other photovoltaic cells in a row can be used as offset pieces. In one embodiment of the method, at least two offset rows can be supplied together for assembly.

[0026] The photovoltaic cells that are assembled into rows can be so-called photovoltaic cell shingles.

[0027] In one embodiment of the method, groups of at least two rows are constructed in parallel, which are then fed to a common assembly. In this way, the number of jointly fed rows can be increased by scaling the method.

[0028] To achieve this object, a device for producing solar modules is also proposed, which device has the central features of the independent claim directed to such a device. To achieve this object, it is thus proposed, in particular, that the device defined at the outset comprise means by which the device is configured to carry out a method according to one of the claims directed to a method for producing solar modules.

[0029] In one embodiment of the device, it can be provided that it has a motorized transfer unit with which at least two rows of photovoltaic cells can be fed together to a solar module to be manufactured.

[0030] A motorized transfer unit can be, for example, a tray, a conveyor table, especially one with a vacuum table, a belt conveyor, especially one with a vacuum table, and / or a vacuum table. Using a vacuum table, it is possible to hold photovoltaic cells arranged in rows on the vacuum table in place using vacuum during feeding for assembly. Fixing photovoltaic cells using vacuum is particularly gentle and can help reduce or even completely eliminate waste in the production of solar modules.

[0031] The motorized transfer unit can be configured to move the photovoltaic cells of the rows from a loading point to an unloading point, where the rows of photovoltaic cells are removed from the transfer unit to equip a solar module.

[0032] At least two support positions, each for one row of photovoltaic cells, can be formed and / or defined on the transfer unit. This makes it possible to use the transfer unit to feed at least two rows of photovoltaic cells together to a solar module assembly.

[0033] In a preferred embodiment of the device, the transfer unit can have at least one row of suction openings for each support location. In this way, rows of photovoltaic cells arranged on the at least two support locations of the transfer unit can be secured to the transfer unit by means of negative pressure.

[0034] The device can have a vacuum generation unit with which rows of photovoltaic cells can be secured to the transfer unit by means of negative pressure, in particular during the joint feeding of at least two rows for equipping a solar module. As already mentioned, the use of negative pressure to secure the rows enables a particularly gentle and therefore efficient fixation of photovoltaic cells during their feeding to the transfer unit. The vacuum generation unit can be connected to suction openings of the transfer unit. The negative pressure generated by the vacuum generation unit can be transferred to the rows of photovoltaic cells via the suction openings of the transfer unit.

[0035] The device can further comprise a dispensing unit for dispensing electrically conductive adhesive onto rows of photovoltaic cells. The dispensing unit can be arranged such that electrically conductive adhesive can be dispensed onto rows of photovoltaic cells arranged on the transfer unit. The dispensing unit can, for example, be arranged between a loading point, at which the photovoltaic cells are arranged on the aforementioned transfer unit to form rows, and an unloading point, at which the rows are unloaded by the transfer unit. In this way, it is possible to apply the electrically conductive adhesive to the rows of photovoltaic cells with the aid of the dispensing unit through a relative movement between the dispensing unit and the transfer unit. The rows can thus be provided with electrically conductive adhesive during their transfer between the loading point and the unloading point.If necessary, the relative movement can be the transfer movement of the lines.

[0036] The dispensing unit can have a number of dispensing nozzles corresponding to a number of support locations for rows of photovoltaic cells of the transfer unit. In this way, it is possible to provide all rows of photovoltaic cells arranged on the transfer unit with electrically conductive adhesive during the transfer. In one embodiment of the device, it is provided that the dispensing unit, in particular at least one dispensing nozzle of the dispensing unit, from which electrically conductive adhesive can be applied to rows of photovoltaic cells, is movable in the longitudinal direction of support locations of the transfer unit for rows and thus in the longitudinal direction of rows arranged on the transfer unit.This makes it possible to apply electrically conductive adhesive to rows of photovoltaic cells that are fed to the assembly using a transfer unit. The transfer unit executes a transfer movement that is oriented transversely or perpendicularly to the longitudinal direction of the rows of photovoltaic cells arranged on the transfer unit. The movement of the dispensing unit, in particular its dispensing nozzles, can then be oriented transversely or perpendicularly to the transfer movement of the transfer unit.

[0037] The device can have a magazine for supplying photovoltaic cells. The magazine can, for example, comprise a conveying means, such as a conveyor belt, on which a supply of photovoltaic cells and / or offset pieces can be moved to a removal position. This promotes a particularly efficient and largely uninterrupted supply of photovoltaic cells for the production of solar modules.

[0038] The device can also have a transfer unit, in particular with a handling robot, for example a swivel arm robot, with which photovoltaic cells can be arranged in rows on the transfer unit.

[0039] Using the transfer unit, the photovoltaic cells and / or offset pieces can be removed, for example, from the aforementioned magazine. The transfer unit, in particular the aforementioned handling robot, can have at least one suction gripper. Using a suction gripper, photovoltaic cells can be gripped and released particularly gently.

[0040] The device can have a control unit for inspecting photovoltaic cells. The control unit can comprise at least one optical control means, for example a camera. In one embodiment of the device, the control unit is provided between a magazine for providing photovoltaic cells and the transfer unit, in particular between the magazine for providing photovoltaic cells and the previously mentioned transfer unit of the device, with which photovoltaic cells can be removed from the magazine and arranged in rows on the transfer unit. This makes it possible to inspect the photovoltaic cells removed from the magazine before they are arranged in rows on the transfer unit.

[0041] The magazine may comprise at least one belt conveyor with which the photovoltaic cells can be brought into a removal position.

[0042] The device may further comprise a loading unit, in particular with at least one gripper, preferably with at least one suction gripper. The loading unit may be configured to receive at least one or several or all rows of photovoltaic cells provided by the transfer unit at a discharge point and / or to transfer them to a downstream

[0043] Processing step and / or handling step, in particular to be transferred to a downstream transport unit of the device. Using the assembly unit, it is possible to equip the solar module with the rows of photovoltaic cells provided by the transfer unit.

[0044] The device can have a transport unit downstream of the transfer unit. Using the transport unit, at least one solar module equipped with rows of photovoltaic cells can be fed to a downstream processing station. A downstream processing station can, for example, be an oven in which electrically conductive adhesive is cured, which can be used to interconnect the rows of photovoltaic cells of a module. A downstream processing station can, for example, also be a packaging and / or loading station. A layup, which can be configured for matrix transfer, can be used as a packaging and / or loading station, for example.

[0045] In one embodiment of the device, it is provided that a transfer movement of the transfer unit is oriented transversely, in particular at right angles, to a longitudinal direction of support locations for rows of photovoltaic cells on the transfer unit or in the longitudinal direction of support locations for rows on the transfer unit.

[0046] In one embodiment of the device, it is provided that a transfer movement of the transfer unit is oriented transversely, in particular at right angles, to a transport movement of the transport unit. In another embodiment of the device, it is provided that a transfer movement of the transfer unit is oriented in the direction of a transport movement of the transport unit. In this embodiment of the device, it can be advantageous if the aforementioned dispensing unit, at least one dispensing nozzle of the dispensing unit, with which electrically conductive adhesive can be applied to the rows of photovoltaic cells, can be moved relative to the transfer unit and in the longitudinal direction of the support locations for rows and thus in the longitudinal direction of the rows of photovoltaic cells arranged on the transfer unit, and / or relative to the transfer unit and transversely or at right angles to the support locations and / or the rows of photovoltaic cells.

[0047] The device may comprise a control unit by which the device is configured to carry out the method according to one of the claims directed to such a method.

[0056] In the following description of various embodiments of the invention, elements that correspond in their function are given the same reference numbers even if they have a different design or shape.

[0057] All figures show a device for producing solar modules 2, designated as a whole by 1.

[0058] Each device 1 has means by which the device 1 is set up to carry out the method for producing solar modules 2 described below.

[0059] Here, photovoltaic cells 3 are assembled into rows 4 and solar modules 2 are constructed from the then electrically connected rows 4.

[0060] The method provides for at least two rows 4, at least three rows 4 in the examples shown in the figures, to be constructed, and for the rows 4 to then be jointly supplied to a solar module 2 for assembly. In all embodiments of devices 1 shown in the figures, the rows 4 are jointly supplied to the assembly of the solar module 2 by means of a motorized transfer unit 5.

[0061] In the embodiment of such a device 1 shown in Figures 1 and 2, a vacuum table is used as the transfer unit 5, which is movable between a loading point 8 and an unloading point 9.

[0062] The device 1 shown in Figures 3 and 4 has a belt conveyor as the transfer unit 5. Through the transfer movement of the belt conveyor, the rows 4, which are assembled on the belt conveyor, can be fed together to the assembly of the solar module 2.

[0063] The device 1 shown in Figures 5 and 6 is also equipped with a transfer unit 5, which is designed as a belt conveyor.

[0064] While in the device 1 shown in Figures 3 and 4 a transfer movement of the transfer unit 5 takes place in the longitudinal direction of the rows 4 arranged on the transfer unit 5, the transfer movement of the transfer unit 5 of the device 1 shown in Figures 5 and 6 is oriented transversely, namely at right angles to the longitudinal direction of the rows 4 of photovoltaic cells 3 constructed on the transfer unit 5.

[0065] In the method, which can be carried out on all three exemplary embodiments of devices 1 shown, it is provided that a relative alignment of the photovoltaic cells 3 within a row 4 and also of the rows 4 to one another, which are built up on the transfer unit 5, is maintained during feeding. A number of jointly fed rows 4 is coordinated with an application speed of an electrically conductive adhesive. The electrically conductive adhesive is applied to the rows 4 of photovoltaic cells 3 in order to mechanically and electrically connect the photovoltaic cells 3 and rows 4 to one another. The application of the electrically conductive adhesive to a row 4 of photovoltaic cells 3 can be carried out with a lateral offset to the longitudinal center axis of a respective row 4.

[0066] Each of the devices 1 shown in the figures has a vacuum generation unit 6, with which rows 4 of photovoltaic cells 3 can be at least temporarily fixed to the respective transfer unit 5 by applying negative pressure. The vacuum generation units 6 are shown only in a highly schematic manner in the figures.

[0067] Each device 1 shown further comprises a dispensing unit 7 for dispensing electrically conductive adhesive onto rows 4 of photovoltaic cells 3 arranged on the transfer unit 5.

[0068] The delivery units 7 of the devices 1 are each arranged between the previously mentioned loading point 8 and the previously mentioned unloading point 9 of rows 4.

[0069] The dispensing unit 7 of the device 1 shown in Figures 1 and 2 as well as 3 and 4 has a number of dispensing nozzles 10 corresponding to a number of support locations 11 for rows 4 of photovoltaic cells 3 on the transfer unit 5. Consequently, the dispensing unit 7 of the devices 1 shown in Figures 1-4 each has three dispensing nozzles 10. Vertical projections of the dispensing nozzles 10 onto support locations 11 for photovoltaic cells 2 on the transfer units 5, which are arranged at least temporarily underneath, can have a lateral offset from the longitudinal center axes of the support locations 11. This allows the application of electrically conductive adhesive to the rows 4 with a lateral offset from a longitudinal center axis of the rows 4.

[0070] The vacuum generation units 6 of the devices 1 are connected to suction openings 23 provided by the respective transfer unit 5. Each transfer unit 5 has at least one row 24 of such suction openings 23 for each of its support locations 11. In this way, the rows 4 of photovoltaic cells 3 can be reliably fixed to the transfer units 5 during their feed.

[0071] In the exemplary embodiment of a device 1 for producing solar modules 2 shown in Figures 5 and 6, the dispensing unit 7 has a dispensing nozzle 10 that can be moved in the longitudinal direction of rows 4 of photovoltaic cells 3 arranged on the transfer unit 5. By moving the dispensing nozzle 10 along the rows 4 arranged on the transfer unit 5, the electrically conductive adhesive can be dispensed row by row onto the rows 4 arranged at least temporarily below the dispensing unit 7. A track along which the dispensing nozzle 10 can be moved during the dispensing of electrically conductive adhesive can have a lateral offset from a longitudinal center axis of a row 4 to be provided with electrically conductive adhesive.

[0072] During the dispensing of electrically conductive adhesive, the position of the dispensing nozzle 10 can be kept constant transversely to the longitudinal extent of the row 4 to be provided with electrically conductive adhesive. In this context, it can be provided that the dispensing nozzle 10 is movable synchronously with the transfer unit 5 in the direction of the transfer movement of the transfer unit 5. In all of the devices 1 shown in the figures, offset pieces 12 are used during the construction of the rows 4 in order to create an offset between adjacent rows 4, initially on the respective transfer unit 5 and later also on the fully assembled solar module 2.

[0073] The offset pieces 12 are photovoltaic cells which have a shorter length compared to other photovoltaic cells, which are designated 3 in the figures and which are not designed as offset pieces 12.

[0074] The figures show that at least two, namely three or even more rows 4 offset from one another are fed together to equip a solar module 2.

[0075] In one embodiment of the method, groups of at least two rows 4 can be constructed in parallel, which are then fed together to a common assembly. One of the transfer units 5 shown in the figures can also be used for this purpose.

[0076] To provide the photovoltaic cells 3 and the offset pieces 12, each of the devices 1 shown in the figures has a magazine 13. With the aid of a transfer unit 14, which has a handling robot 15, namely a swivel-arm robot, the offset pieces 12 and photovoltaic cells 3 stored and provided in the respective magazine 13 can be removed and arranged in rows 4 on the respective transfer unit 5. Each magazine 13 has a total of two conveyor belts 16, on which the offset pieces 12 and the comparatively somewhat longer, regular photovoltaic cells 3 are stored in stacks. To check the photovoltaic cells 3 and offset pieces 12, each device 1 has a control unit 17.The control units 17 are arranged between the magazine 13 and the transfer unit 14 of the respective device 1 and each comprise at least one optical control means, for example a camera 18.

[0077] With the help of the handling robot 15 of the transfer unit 14, the photovoltaic cells 3 and / or offset pieces 12 removed from the magazine 13 can be presented to the camera 18 of the control unit 17 in order to inspect the photovoltaic cells 3 and offset pieces 12 before their arrangement on the respective transfer unit 5. Each of the devices 1 has a loading unit 19 downstream of the respective transfer unit 5 and also downstream of the unloading point 9. Each loading unit 19 comprises several grippers 20 designed as suction grippers.

[0078] The assembly units 19 are configured to receive one or more or even all rows 4 of photovoltaic cells 3, which are provided by the respective transfer unit 5 at the unloading point 9, and to transfer them to a downstream transport unit 21 of the respective device 1. The respective transport unit 21 serves to supply at least one solar module 2 equipped with rows 4 of photovoltaic cells 3, 12 to a downstream processing station, for example, a furnace.

[0079] As already mentioned above, a transfer movement of the transfer unit 5 of the devices 1 shown in Figures 1-4 is aligned in the longitudinal direction of support locations 11 and thus also in the longitudinal direction of rows 4 on the transfer unit 5. In the embodiment of the device 1 shown in Figures 5 and 6, the transfer movement of the transfer unit 5 is aligned transversely, namely at right angles to a longitudinal direction of support locations 11 and thus transversely, namely at right angles to a longitudinal direction of the rows 4 arranged on the support locations 11 of the transfer unit 5.

[0080] The transfer movements of the transfer unit 5 of the devices 1 shown in Figures 1-4 are oriented transversely, namely at right angles to the transport movement of the respective transport unit 21 which is arranged downstream of the transfer unit 5.

[0081] In the embodiment of the device 1 shown in Figures 5 and 6, the transfer movement of the transfer unit 5 is aligned in the direction of a transport movement of the transport unit 21 used there.

[0082] The transport unit 21 of the device 1 shown in Figures 5 and 6 is, like the transfer unit 5, designed as a belt conveyor.

[0083] To carry out the method described above, each of the devices 1 shown in the figures further comprises a control unit 22. This control unit 22 can control the aforementioned functional units of the respective device 1 as provided for by the method.

[0084] The invention relates to improvements in the technical field of solar module production. Among other things, a method for producing solar modules 2 is proposed, in which at least two or more rows 4 of photovoltaic cells 3 are jointly fed into a solar module 2 assembly.
