Description

EQUIPMENT OF A TRANSPORT UNIT DURING THE SOLAR PANEL PRODUCTION FIELD OF INVENTION The invention relates to a method for producing solar panels, wherein the solar elements are assembled in rows, wherein each row has at least two solar elements, and wherein the solar panels are assembled from electrically connected rows. BACKGROUND OF THE INVENTION Solar elements that are assembled in rows can be solar cells, photovoltaic solar cells, photovoltaic cells or partially cut parts of them, called tiles, for example, solar cell tiles or photovoltaic cell tiles. In this process, it is possible to transfer individual solar elements or the basic elements of a solar cell row by row to a transfer unit, move the transfer unit to an assembly area, and deposit the solar elements in the assembly area row by row onto a tray or other transport unit, particularly a motorized transport unit. Placing the solar element onto the motorized transport unit to form a solar panel is also known as Ref. 349179 Solar panel equipment. Therefore, the assembly area is also known as the equipment, assembly, or mounting area. For solar panel assembly, particularly for a one-piece solar panel, the rows—that is, the rows of solar elements or solar elements arranged row by row—can be arranged overlapping each other along a longitudinal axis of two rows placed side by side. In the overlapping area, an adhesive or other bonding agent can be applied to connect the adjacent rows. For example, the adhesive can be applied to the solar elements or to the rows located on the transfer unit. Dispensing units can be used to apply the adhesive. For example, dispensers capable of linear adhesive applications can be used. Alternatively, the adhesive can be applied by means of a pressure device. For example, the adhesive can be applied by a printing process, such as ribbon printing or screen printing.The rows provided with the adhesive can be aligned and joined side by side or with each other in the motorized transport unit and thus be assembled into a solar panel. US 2016 / 163914 Al and US 2018 / 175233 Al describe systems and processes for the production of solar panels. In such methods, the time required between the provision of an individual solar element and the assembly of a solar panel with that individual solar element, also known as the cycle time, plays a crucial role. A shortened cycle time leads to a significant reduction in the processing time for the production of the entire solar panel. The object of the invention is, therefore, to increase the efficiency of a process for the production of solar panels, in particular to accelerate the process. SUMMARY OF THE INVENTION The solution to this problem in the method mentioned at the beginning consists in particular in that, in accordance with the invention, to equip the solar panel at least two rows are received in one phase of operation and are kept ready at different heights above the solar panel and that the rows to equip the solar panel are lowered together only to the point where only the row to be equipped currently comes into contact with the solar panel. The invention is based on the knowledge that the cycle time can be shortened by carrying out individual process steps for several solar cells simultaneously. For example, in the method according to the invention, several rows, i.e., at least two rows, are received in one operating phase by the transfer unit via a receiving device in order to place them into the motorized transport unit in a subsequent step. The motorized transport unit is, for example, a tray or a conveyor belt. In this case, the method according to the invention also allows for the successive depositing of at least two overlapping rows after placement. This reduces the number of receiving processes, as well as the travel distance of the receiving device within a solar panel production process, and shortens the time required for the production process. Therefore, the efficiency of the process mentioned at the beginning is increased. In one embodiment, the remaining rows are vertically spaced from the solar panel. For example, two or three rows are received simultaneously by the receiving device and suspended above the solar panel. In the method according to the invention, the receiving device can be approached vertically from the solar panel until a first row, or the current row to be mounted, makes contact with the solar panel—for example, by overlapping a previously positioned row, and a second and third row, or the remaining rows, remain vertically spaced from the solar panel due to their vertical distance from the solar panel when the first row makes contact. In this way, the solar panel can be equipped with one row by the receiving device while simultaneously mounting several rows. The solar panel can be equipped with the other rows in one or more mounting steps. In one embodiment, the rows are secured with vertically adjustable suction cups, preferably against a restoring force. For example, solar elements arranged in rows are secured by at least one suction cup. The suction cups can be arranged so that the suction cups for the first row project vertically above the suction cups for the second row in the direction of the rows to be secured. The suction cups for the second row, in turn, can project vertically above the suction cups for a third row in the direction of the rows, and so on. This allows for selective securing and positioning of individual rows, for example, positioning the first row without positioning the second row.Suction cups, which, for example, can be adjusted vertically against a restoring force, allow a second row to be secured and positioned after the first row has been secured and positioned, particularly before securing or positioning one or more third rows. In other words, this allows several rows to be secured together, especially with subsequent selective placement of the rows that were secured together. IVIA / a / ZUZÓ / UII According to the invention, the solution to the problem mentioned at the beginning in the method of the type mentioned at the beginning consists, in particular, in the fact that two successive rows cover different distances during the loading process. For example, the receiving device moves perpendicular to the rows, i.e., perpendicular to a longitudinal direction of the rows, during the loading process. For example, the receiving device receives a first row and at least a second row. In this case, for example, after placing the first row on the motorized transport unit and before placing the second row on the motorized transport unit, the receiving device moves perpendicular and relative to the first row, for example, it is moved by motorization or mechanical means.In this way, during the setup process, a movement of the motorized transport unit is complemented and / or replaced by a movement of the receiving device that moves the rows from the transfer unit to the transport unit. This allows the individual rows to be arranged in the transport unit in a timely and spatially efficient manner. In accordance with the invention, it is foreseen that during an equipment process to equip the panel IVIA / a / ZUZÓ / UII solar, two successive rows are received in one phase of operation. In accordance with the invention, it is further provided that the two successive rows travel different distances during the equipping process. In one configuration, the solar panel remains stationary during the assembly process with the two consecutive rows. In other words, the transport unit does not move during assembly in this configuration. In this configuration, the receiving device can be moved perpendicular to the first row after the first row has been placed, and then the second row can be placed to assemble the solar panel on the transport unit, overlapping the first row. In this way, the relative arrangement of the rows can also be determined and adjusted, at least in part, by moving the receiving device. Alternatively, the transport unit moves during assembly. In one embodiment, the solar panel is designed to move intermittently between two loading processes. Intermittent movement of the solar panel or the transport unit can be advantageous when loading the transport unit with the rows. During loading, the rows are aligned and connected to each other on the transport unit. Through intermittent forward movement, space can be created at the loading point for new rows to be loaded onto the transport unit. Thus, it is conceivable that the receiving device moves to successively deliver all the received rows, while the transport unit moves when the receiving device is to receive a new load. In one modality, the solar panel is expected to move intermittently between two equipment processes, i.e., between a deposit of the rows received in one phase of operation and a deposit of additional rows received in a further phase of operation. In this way, the relative arrangement of the rows during setup can be determined solely by the movement of the receiving device, while the movement of the transport unit allows for a smaller and therefore shorter travel distance for the receiving device during setup. This simplifies the setup of the transport unit, making it faster and more precise. In one configuration, the solar panel is designed to move continuously during the installation process. Specifically, the solar panel moves perpendicular to the rows during installation. In other words, the transport unit moves continuously during the installation process. This allows the solar panel production process to be accelerated even further. This is particularly true because a die moves during and after the module is fitted with it, thus reaching a subsequent processing step more quickly. In a later step of the process, the solar panels can be moved, for example, to a thermally influenced area, such as an oven, for heat treatment, i.e., adhesive curing. The solar panels can still be positioned on the transport unit. Continuous movement of the transport unit is advantageous in this regard. Synchronous movement creates overlapping areas of thermal action, caused by varying residence times of the solar cell rows under the heat, resulting in either excessively strong or insufficient thermal action and, consequently, a striped pattern. In contrast, with continuous movement of the solar panel or the transport unit, the solar panel moves uniformly across a thermally influenced area where the adhesive applied to and between the rows cures. The movement of the transport system can be compensated for by a corresponding movement of the receiving device during row placement. This prevents relative movement of the transport unit with respect to the receiving device during row placement. Alternatively, the duration of the placement process can be chosen, in particular made so short, that the relative movement described is negligible during row placement. According to the invention, the solution to the problem mentioned at the beginning consists in particular of providing a device for the production of solar panels, in which the solar elements are assembled in rows, in which each row has at least two solar elements and in which the solar panels are assembled from rows electrically connected to each other, the device comprising a receiving device designed to receive at least two rows in an operational phase to equip the solar panel and hold them prepared at different heights above the solar panel and lower the rows together to equip the solar panel only to such an extent that only the row to be equipped at that time comes into contact with the solar panel. In one embodiment, the receiving device is expected to be designed to keep the remaining rows vertically spaced from the solar panel. In one embodiment, the receiving device is expected to preferably include vertically adjustable suction cups against a resetting force, which are designed to receive the spools, in particular to receive the spools together in an operating phase. According to the invention, the solution to the problem mentioned at the beginning consists in particular of providing a device for the production of solar panels, in which the solar elements are assembled in rows, each row having at least two solar elements, and the solar panels are assembled from rows electrically connected to one another. The device comprises a receiving device designed to travel different distances for at least two consecutive rows during the assembly process. To this end, the receiving device can be moved in the direction of travel of the conveying device and / or in a vertical direction, for example, along the length of the rows. According to the invention, the receiving device is provided to accommodate at least two consecutive rows in one phase of operation during an outfitting process to equip the solar panel. In accordance with the invention, it is further provided that the receiving device is prepared to travel paths of different lengths for at least two consecutive rows during the equipping process. In one embodiment, the receiving device is preferably movable relative to the solar panel during the installation process, particularly in a direction transverse to the rows. Alternatively or additionally, the receiving device is preferably movable in a direction along the rows during the installation process. In one embodiment, the device is expected to include a transport unit to receive the solar panel and that the device is designed to keep the transport unit stationary during the process of equipping the two consecutive rows. In one configuration, the device is designed to move the transport unit synchronously between two equipment processes. In another configuration, the device is designed to move the transport unit intermittently between two equipment operations, i.e., between placing the received rows in one operation phase and placing other received rows in a subsequent operation phase. In one configuration, the device is designed to move the transport unit continuously, especially during the outfitting process.

DETAILED DESCRIPTION OF THE INVENTION Figure 1A shows a first device 1 for the production of solar panels 14 in a three-dimensional view. The device 1 comprises a transport unit 2, a transfer unit 3, and a receiving device 4. As shown in Figure 1A, solar elements 15 are arranged in rows on the transfer unit 3. In this example, the solar elements 15 have an elongated configuration, similar to roof tiles. The solar elements 15, which are strips of wafer material, are also referred to as roof tiles. The rows arranged on the transfer unit 3 are received by the receiving device 4 and placed onto the transport unit 2. In one or more previous steps, the solar elements 15 are supplied to a provisioning unit 5 and placed onto the transfer unit 3 by a handling unit 6.The previous step(s) can be controlled by a monitoring system 13, such as a sensor and / or camera system. The individual solar elements 15 from different rows can be arranged side-by-side in the transfer unit 3 in each case in a direction perpendicular to the rows (or perpendicular to a longitudinal direction of the rows). Alternatively, the individual solar elements 15 from different rows can be spaced transversely to the rows and staggered relative to each other in the longitudinal direction to the rows, as shown in Figure 1A, in a so-called wall pattern. The transfer unit 3 can move parallel to, i.e., in one direction along the rows, the rows deposited onto the transport unit 4. The transfer unit 3 can also move relative to the transport device 4. In this way, the transfer unit 3 can move from a first position, where the transfer unit 3 is equipped with the solar elements 15 by the handling unit 6, to a second position, where the rows are received by the receiving device 4 and placed onto the transport unit 4. On the way from the first to the second position, the solar elements 15, or the rows, are provided with an adhesive along at least one longitudinal axis of the rows. The application of the adhesive is carried out by several supply units, in the example shown by several dispensers 7, for example, one dispenser per row.Alternatively, the adhesive can be applied by a single dispenser 7 (see Figures 3A-3C). Alternatively, the adhesive can be applied by a printing process, for example, screen printing or roller printing, using printing units, for example, screen printing units or roller printing units. After applying the adhesive, the rows arranged on transfer unit 3 can be connected in transport unit 4 to the rows already deposited there. A newly deposited row is connected by partially overlapping the new row onto a previously deposited row, ensuring the adhesive comes into contact with both the previously deposited and the new row. In other words, the rows arranged in transport unit 4 partially overlap, particularly in an area of ​​the applied adhesive. In a subsequent process step, the rows arranged in transport unit 2 and assembled to form a solar panel 14 can be moved in transport unit 2. Transport unit 2 is, for example, a IVIA / a / ZUZÓ / UII tray or a conveyor belt. The transport unit 2 can be a motorized transport unit. In the next step of the process, the equipped solar panel 14 is driven, for example, to a thermal influence area, for example, an oven, to cure the adhesive and thus firmly connect the rows within the solar panel 14 to each other. Transport unit 2 can be moved continuously or intermittently during and / or after the outfitting process. Specifically, transport unit 2 can be moved continuously during and after the outfitting process. Alternatively, transport unit 2 can be moved intermittently during the outfitting process and continuously after the outfitting process. Figure IB shows the first device 1 of Figure 1A in the top plan view. Identical or similar features are provided with the same reference symbols. Figure 2A shows a second device 1A for producing solar panels 14 in a three-dimensional view. The second device 1A is similar to the first device 1 shown in Figures 1A and 1B. Identical or similar features are provided with the same reference symbols. Instead of the transfer unit 3 of device 1, device 1A comprises a transfer unit 3A. The transfer unit 3A is designed as a conveyor belt. The conveyor belt extends from the first position of the transfer unit 3 described in Figures 1A and 1B to the second position of the transfer unit 3. The conveyor belt can move parallel to the rows arranged on it and parallel to the rows deposited on the transport unit 2. In other words, the conveyor belt can move in a longitudinal direction along the rows.In this way, the solar elements 15 placed in the transfer unit 3A and arranged in rows, by means of the movement of the conveyor belt, can be moved from the first position to the second position, from which they are placed on the transport unit 2 by means of the receiving device 4. Figure 2B shows the second device 1A in top plan view. Figure 2C shows the second device 1A in side elevation view. Identical or similar features are provided with the same reference symbols. Figure 3A shows a third device IB for the production of solar panels 14 in a three-dimensional view. The third device IB is similar to the first device 1 and the second device 1A shown in Figures 1A-1B and 2A-2C. Identical or similar features are indicated with the same reference symbols. Instead of the transport unit 2 of the first device 1, device IB comprises a transport unit 2A, which is configured as a conveyor belt. Instead of the transfer unit 3A of the second device 1A shown in Figures 2A-2B, the third device IB comprises a transfer unit 3B, which is configured as a conveyor belt. The conveyor belt 3B is movable perpendicular to the rows arranged on the conveyor belt. Consequently, the transport unit 2A, the transfer unit 3B, the handling unit 6, and the preparation unit 5 are arranged in a row perpendicular to the rows of the transport unit 2A and the transfer unit 3B. Similar to the arrangement of the third device IB shown in Figure 3A, it is conceivable that the transfer unit 3 of the first device 1 shown in Figures 1A and IB is arranged in a row with the transport unit 2, the handling unit 6, and the preparation unit 5. In such an arrangement, the transfer unit 3 can be movable perpendicular to the rows arranged in the transfer unit 3 or in the transport unit 2, similarly to transfer unit 3B. Alternatively, in such an arrangement, the first position of the transfer unit 3, in which the transfer unit 3 is equipped with the solar elements 15 by the handling unit 6, can coincide with the second position of the transfer unit 3, in which the solar elements 15 are taken from the transfer unit 3 by the receiving device 4 and placed in the transport unit 2.In this way, the transfer unit would not need to be moved between loading and unloading. One of the advantages of the arrangement shown in Figure 3A is that the transfer unit 3B can be unloaded by the receiving device 4 and loaded by the handling unit 6 simultaneously. Figure 3B shows the third device IB in top plan view. Figure 3C shows the third device IB in side elevation view. Identical or similar features are provided with the same reference symbols. Figure 4A shows the receiving device 4 positioned above the transfer device 3. The transfer unit 3 is, in turn, located above the transport unit 2. In other words, the transfer unit 3 is positioned in the second location of the transfer unit 3 described with reference to Figures 1A and 1B. Alternatively, the transfer unit 3 of the first device 1 could be the transfer unit 3A of the second device 1A or the transfer unit 3B of the third device 1B. The transport unit 2 of the first device 1 could be the transport unit 2A of the third device 1B. The receiving device 4 includes one or more suction cups. In the example shown, the receiving device comprises several suction cups arranged in series, with which the receiving device 4 can receive the rows. In the example shown, the suction cups are arranged in three series. In the example shown, the respective series of suction cups extend perpendicular to the picture plane. The suction cups are arranged such that a first suction cup or several suction cups arranged in a first series (in Figures 4A-4H, the left series of suction cups) come into contact with a row of one or more solar elements 15 after a vertical movement of the receiving device 4 toward the transfer unit 3, while one or more other suction cups of another series (in Figures 4A-4H, the suction cups of the central and right series of suction cups) are vertically spaced from the rows or solar elements 15. If the vertical movement of the receiving device 4 continues in the direction of the transfer unit 3, then the additional suction cups approach other rows or additional solar elements 15 of other rows. In the case of this additional vertical movement, i.e., in the case of a vertical movement in the direction of the transfer unit 3 after the first suction cup or the first series of suction cups is already in contact with a solar cell, these first suction cups adjust vertically, for example, against a resetting force. The vertical adjustment of the suction cups allows for vertical movement of the receiving device 4 after the suction cups come into contact with the solar elements 15 without destroying or damaging the solar elements 15. Due to the vertical adjustment, the suction cups can be arranged at the same height relative to each other. By means of a further vertical movement of the receiving device 4 in the direction of the transfer unit 3, finally a series of second suction cups, in the example shown the central series of suction cups, and finally a series of third suction cups, in the example shown the right series of suction cups, as shown in Figure 4B, respectively come into contact with other solar elements 15. By means of a vertical movement of the receiving device 4 away from the transfer unit 3, the individual solar elements 15 are received by the transfer unit 3 via the receiving device 4. Furthermore, the suction cups are returned to their original position by the reset force, so that the suction cups of different series are spaced differently from the transfer unit 3 and the transport unit 2. This is shown in Figure 4C. Due to the different vertical arrangement of the suction cups or series of suction cups, the received solar elements 15 or rows are arranged at different vertically spaced heights relative to the transfer unit 3 and the transport unit 2. The receiving device 4 is translationally mobile in a direction perpendicular to the rows or towards the solar panel 14, as shown in Figure 4D. In this way, the solar elements 15 or received rows are arranged vertically spaced at different heights relative to the transport unit 2 due to the different vertical arrangement of the suction cups or series of suction cups. The receiving device 4 may include suction cups, for example, a series of suction cups, which are not vertically adjustable. For example, the series of suction cups that has the greatest vertical distance to the transfer unit 3 or the transport unit 2 cannot be adjusted vertically. In the example shown, this is the right-hand series of suction cups. As shown in Figure 4E, a first row is placed in contact with transport unit 2 or with a row already positioned on transport unit 2, while other rows—in the example shown, a second central row and a third right row on transport unit 2 or solar panel 14—are arranged vertically, spaced apart. In other words, the rows will only be lowered to the extent that only the row currently being mounted comes into contact with solar panel 14 to equip the solar panel 14. By moving the receiving device 4 and / or the transport unit 2 perpendicular to the rows or to a longitudinal axis of the rows, the other rows received by the receiving device 4 can be deposited into the transport unit 2, as shown in Figures 4G and 4H. In other words: during the process of equipping solar panel 14, the second row (in the example shown, the central row) travels a different distance, i.e., a longer distance than the first row (in the example shown, the left row). Thus it is possible, as shown in figures 4E4H, to place a second row vertically on a suitable deposit position to move the receiving device 4 vertically towards the transport unit 2 until the solar elements 15 received by the series of second suction cups come into contact with the transport unit 2 or the previously deposited row. During this process, the transport unit 2 makes contact with the first set of suction cups, as shown in Figure 4H. The vertical movement of the receiving device 4 in the direction of the transport unit 2 after the contact of the transport unit 2 by the first set of suction cups leads to a vertical adjustment of the first set of suction cups. For example, during the fitting process shown in Figure 4D-4H, the solar panel 14 or the transport unit 2 can remain stationary or move continuously. Between two fitting processes, i.e., between the deposit of the three received rows of solar elements 15 and the deposit of another three received solar elements 15, the solar panel 14 or the transport unit 2 can be moved, for example, continuously and / or intermittently to free up more space in the transport unit 2 for fitting. Figure 5A shows a second receiving device 4A similar to the first receiving device 4 shown in Figures 1A-4H. The second receiving device 4A comprises a number of suction cups 8, arranged in two series, in side view. The suction cups 8 may correspond to the suction cups of the first receiving device 4. IVIA / a / ZUZÓ / UII The suction cups 8 arranged in the first series are vertically spaced at a first distance relative to a reference plane located below the receiving device 4A, for example, the transfer unit 3 or the transport unit 2. The suction cups 8 arranged in the second series are vertically spaced at a second distance relative to the reference plane. The second distance is greater than the first distance. The first and second distances can be changed by the vertical movement of the receiving device 4A relative to the reference plane. If a suction cup 8, located in the first series, strikes the reference plane and the vertical movement of the receiving device 4A continues in the direction of the reference plane, this suction cup 8 undergoes a vertical adjustment, particularly relative to the receiving device 4A.In the example shown, the suction cup 8 moves relative to the receiving device 4A in a direction opposite to the direction of movement of the receiving device 4A, i.e., away from the reference plane. The vertical adjustment is performed against a restoring force, which is provided by an elastic element 9 in the example shown. Each suction cup 8 comprises a vacuum suction unit 10, for example, a suction head. The vacuum suction unit 10 can receive a solar element by creating negative pressure on the surface of the solar element 15 and deposit it again by restoring ambient pressure or generating positive pressure. The respective pressure condition can be provided, for example, by a pumping device (not shown) connected to the suction cups 8. Similarly, the solar elements 15 in the transport unit 2 or 2A, as well as in the transfer unit 3, 3A, or 3B, can be secured in the respective transport or transfer unit by generating negative pressure on one side of the solar elements 15 (e.g., the side furthest from the receiving device 4 and / or the handling unit 6). The vacuum can be provided, for example, through openings in the respective transport or transfer unit that are connected to the pumping device (not shown). Figure 5A shows a receiving device 4A in a three-dimensional visca, which is arranged on the transport unit 2. Identical or similar features are provided with identical or similar reference symbols. In the example shown, the suction cups 8 comprise, in addition to the elastic element 9, a retaining ring 11 and a spring piston 12.
