Description

Technical Field

[0001] The present invention relates to a method and apparatus for arranging ribbons and solar cells in a facility for manufacturing solar panels. Background Art

[0002] A facility for producing solar panels has several workstations. Typically, a panel is formed by attaching strings of solar cells, and after attaching a plurality of strings in parallel to one another, the resulting assembly is installed, thereby producing a solar panel.

[0003] Each string of cells comprises a given number of cells connected in series and connected by several cables (also called ribbons or strips) that are electrically conductive and run in parallel (connecting the positive of one cell to the negative of the next, interlacing all the cells and ending with one positive pole and another negative pole, which constitute the external connections of the resulting photovoltaic module). As a general rule, the cables are wound independently.

[0004] Continuing with the traditional method for producing a battery string, the batteries are first arranged on a platform (typically a conveyor belt). A tool grasps one end of each cable and, by stretching it, positions a section of each unrolled cable over the battery, so that the first section of the cable is on the battery and the second section is on the platform. A new battery is then placed on the second section of the cable. Suction is applied from the bottom of the conveyor belt to secure the battery and cables in place.

[0005] Each cell has a given welding area, which is configured so that the cable is attached to the cell in said area. With this type of method, the problem is that there is no guarantee that the second part of the cable is arranged exactly under the welding area of the corresponding cell. However, such an alignment error between the cable and the cell does usually allow a sufficient electrical connection to be achieved, so this method of alignment before welding is usually accepted. This is because one side of the solar panel (i.e. the side corresponding to the second part of the cable) is located at the rear and is usually opaque in the case of "single-sided" type panels and is therefore hidden from view (not visible).

[0006] However, new demands are being made for solar panels with exposed sides, as they offer improved efficiency. In these cases, while the electrical connection to the second portion of the cable remains acceptable, the aesthetics are unacceptable. This has necessitated the search for new methods of creating cell strings that eliminate the aforementioned drawbacks.

[0007] Besides the aesthetic drawbacks, the increasing efficiency of photovoltaic panels requires an increasing number of cables to extract the generated current, while the cross-section of each of these cables decreases. Reducing the cross-section of these cables means reducing their width, and alignment errors between photovoltaic cells and cables begin to become a limiting factor, given that the electrical connection is seriously compromised if the alignment error is greater than the width of the cable. In the event of significant alignment errors, this leads to a situation where interconnections by soldering or conductive adhesives do not allow electrical transmission, as the area provided in the cell for interconnection is completely separate from the cable.

[0008] EP1974396A1 describes an apparatus and method for solving this problem. The proposed solution modifies the concept of the described facility. In this case, the cut cables are placed on a conveyor belt and positioned in the desired location using the necessary means. This ensures that the second portion of the cable is in the desired position, thus resolving the aforementioned problem. However, this conceptual change necessitates a complete redesign of the facility, and in addition to being more complex due to the increasing number of required components, it also requires more space.

[0009] US2017 / 0229602A1 also discloses an apparatus and method for solving the initially described problem, and in this case does not require modifying the concept of the installation (unlike the one proposed in EP1974396A1). In this case, the second portion of the cable is arranged on a platform or conveyor belt as the cable is unrolled, thus maintaining the general concept of this type of installation. The biggest problem with this type of installation for arranging or fixing the second portion of the cable in place is that, due to the suction force usually applied to fix the battery in place, the cables have zero accessibility from the area below. To avoid this problem and address the aforementioned issues, this document discloses a solution in which the second battery is arranged in a cantilevered manner, that is, one end is not supported on the platform or conveyor belt, making the second battery and therefore the second portion of the cable accessible from below. With this solution, the belt can thus be conveniently fixed from below, without having to omit this section to do so. To this end, the solution involves the incorporation of an additional tool that acts from below and has special characteristics to allow the second portion of the cable to be gripped and positioned or fixed in the desired position. Summary of the Invention

[0010] The object of the present invention is to provide a method and an apparatus for arranging ribbons and solar cells in a facility for manufacturing solar panels.

[0011] A first aspect relates to a method for arranging ribbons and solar cells in a facility for manufacturing solar panels. In this method, at least one ribbon (which is electrically conductive and is also referred to as a strip or cable, for example) of a given length having a first longitudinal end and an opposite second longitudinal end is arranged in a desired position so that the ribbon extends longitudinally.

[0012] The strip is arranged on a support surface when in a desired position, and with the strip arranged in the desired position, the second longitudinal end of the strip is laterally guided by a guide device, the guide device including a guide section having at least one longitudinal slot or groove, the second longitudinal end of the strip being received or arranged in the longitudinal slot or groove, such that the guide device prevents lateral movement of the second longitudinal end, and is at least partially arranged on or above the support surface for laterally guiding the second longitudinal end; and a battery is arranged in a first attachment position, wherein a first portion of the battery is arranged on the strip and a second portion of the battery is arranged on the guide section of the guide device at least partially arranged on or above the support surface, such that in the first attachment position, the battery is deformed. The guide device is then removed to release the strip (the second longitudinal end of the strip) from the guide device, such that the second portion of the battery falls onto the second longitudinal end of the strip.

[0013] To remove the guide means, a linear longitudinal movement of the guide means in the removal direction is caused, with the guide means being moved away from the first longitudinal end of the belt. After the guide means are removed, the battery and the belt are moved together in a linear longitudinal forward movement direction opposite to the removal direction, and the battery is arranged in a second attachment position.

[0014] Thus, in the interval that elapses between the placement of the strip in the desired position (and guided by the guide means) and the placement of the battery on the strip, the second longitudinal end of the strip is held transversely fixed as a result of the guide means (lateral guidance is therefore transverse fixing) and is correctly positioned relative to the battery when the battery falls onto the second longitudinal end of the strip. This is achieved, for example, without having to place parts of the battery in a cantilevered manner due to the fact that the deformation of the battery provided by the guide means prevents the need to fix the second longitudinal end from below.

[0015] A second aspect relates to an apparatus for arranging ribbons and solar cells in a facility for manufacturing solar panels. The apparatus includes a first conveyor configured to arrange at least one ribbon of a given length having a first longitudinal end and an opposite second longitudinal end in a desired position such that the ribbon extends longitudinally. The first conveyor is configured to arrange the ribbon on a support surface.

[0016] The device further comprises a guide device comprising a guide section having at least one longitudinal slot or groove for receiving the second longitudinal end of the belt, the guide section being configured to cooperate with the second longitudinal end of the belt arranged in the desired position when the guide device is in the guiding position (fixed position). By said cooperation, the guide device guides the second longitudinal end transversely, thereby preventing lateral movement of the second longitudinal end.

[0017] The apparatus further comprises a second conveying device configured to arrange the battery in a first attachment position when the belt is in a desired position and the guide device is in a fixed position, such that in the first position a first portion of the battery is arranged on the belt and in contact with the belt, and a second portion of the battery is arranged on the guide device without contacting the belt, the battery being deformed in the first attachment position; a third conveying device configured to move the guide device between a guiding position and a removal position in which the guide device does not cooperate with the second longitudinal end; and a control device configured to control actuation of the first, second and third conveying devices.

[0018] The control device is further configured to, once the first conveyor device has arranged the battery on the guide device, cause the third conveyor device to move the guide device from the guiding position to the removal position by linear longitudinal movement of the guide device in the removal direction. The apparatus further comprises a fourth conveyor device configured to move the belt together with the battery arranged on the belt in a linear longitudinal forward movement direction opposite to the removal direction until the battery is arranged in the second attachment position.

[0019] The device also achieves the advantages described for the method.

[0020] These and other advantages and features of the present invention will become apparent in view of the accompanying drawings and detailed description of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A first aspect of the invention relates to a method for arranging ribbons and solar cells in a facility for manufacturing solar panels. In this method, at least one ribbon 1 of a given length and having a first longitudinal end 1.1 and an opposite second longitudinal end 1.2 is arranged at a desired location so that the ribbon 1 extends longitudinally at the desired location. The ribbon 1 is arranged to extend on a support surface, which preferably comprises a conveyor belt 4, such as Figure 1 As depicted in FIG. , a plurality of belts 1 are preferably arranged in parallel. For the sake of clarity, Figure 1 The belt 1 is depicted separated from the conveyor belt 4, but said belt 1 will actually be arranged on said conveyor belt 4 (at least the second end 1.2, as explained below).

[0027] Preferably, in order to arrange the tape 1 in the desired position, the free end of a coil is grasped, said end thus grasped is longitudinally moved in the forward movement direction A, thereby unwinding it (the center of the coil does not move longitudinally, but rotates as the coil is pulled), until an unwound section of a given length, equal to a given length of the tape 1, is arranged in the desired position, and said section is cut, thereby separating it from the coil, so that the cut section becomes the tape 1. The previously grasped free end is the first longitudinal end 1.1 of the tape 1 (of the cut section).

[0028] When the belt 1 is arranged in the desired position, the second longitudinal end 1.2 of the belt 1 is guided transversely by the guiding means 2, as shown in FIG. Figure 1 Depicted in. Figure 2a 、 Figure 2b and Figure 2c The guide device 2 depicted as an example in FIG. 1 comprises a guide segment 2.1 cooperating with the second longitudinal end 1.2 so that the guide device 2 prevents lateral movement of the second longitudinal end 1.2. To this end, when the belt 1 is arranged on the support surface in the desired position, the guide device 2 is arranged in the guide position 2P1 (see FIG. Figure 1 ), at least partially arranged on or above the support surface. The belt 1 can be arranged in the desired position before the guide device 2 is arranged in the guide position 2P1, after the guide device 2 is arranged in the guide position 2P1, or at the same time as the guide device 2 is arranged in the guide position 2P1.

[0029] The guiding device 2 comprises in the guiding section 2.1 at least one longitudinal slot 2.0 or groove for arranging or to be arranged each strip 1 in the desired position, the second longitudinal end 1.2 of the strip 1 being arranged or accommodated in said slot 2.0 when the guiding device 2 guides said second longitudinal end 1.2 laterally, said guiding device 2 thus cooperating with said second longitudinal end 1.2. Figure 2c The cooperation is depicted schematically, the separation between the second longitudinal end 1.2 and the wall of the guiding means 2 delimiting the slot 2.0 having been exaggerated for the sake of clarity, and it can be seen how the slot 2.0 prevents lateral movement (in direction X) of the second longitudinal end 1.2 and thus guides it laterally.

[0030] exist Figure 1 In the diagram, for the sake of clarity, the guide 2 is arranged separate from both the belt 1 and the conveyor belt 4, but in practice it will preferably be at the same level as the conveyor belt 4, and a portion of the belt 1 will be accommodated in the slot 2.0 of said guide 2 (this portion of the belt 1 is at Figure 1 is depicted below the guide device 2).

[0031] With the strip 1 positioned in the desired position and the guide device 2 in the guiding position 2P1, in this method, the solar cell 3 is positioned in a first attachment position 3P1. In this first attachment position 3P1, the first portion 3.1 of the solar cell 3 is positioned on the strip 1 (in contact with the strip 1), and the second portion 3.2 of the solar cell 3 is positioned on the guide segment 2.1 of the guide device 2 (out of contact with the strip 1). The first portion 3.1 and the second portion 3.2 are arranged longitudinally relative to the strip 1. Thus, while in the first attachment position 3P1, the solar cell 3 is in contact with the strip 1 (the first portion 3.1) and, with the strip 1 positioned on a support surface, presses the strip 1 against the support surface. When both the strip 1 and the guide device 2 are positioned on the support surface, the strip 1 lies in the plane of the support surface, while the guide segment 2.1 protrudes above the plane, causing the solar cell 3 to deform in the first attachment position 3P1. Figure 1 The belt 1 is shown in its desired position on the conveyor belt 4, the deformed battery 3 in its first attachment position 3P1 and the guide 2 cooperating with the belt 1, but for the sake of clarity the belt 1 is shown separated from the battery 3 and the conveyor belt 4. Figure 1 In FIG, the battery 3 is also depicted as being separated from the remaining components for the sake of clarity.

[0032] As described above, since the strap 1 is extended and its second longitudinal end 1.2 is received or arranged in the guide section 2.1 of the guide device 2, thereby preventing lateral movement of the second longitudinal end 1.2, the guide section 2.1 at least partially protrudes above the strap 1 (conversely, the second longitudinal end 1.2 will not be received in the guide device 2). Since the second portion 3.2 of the battery 3 is arranged on the guide section 2.1, the second portion 3.2 does not contact the strap 1 and the battery 3 is deformed when in the first attachment position 3P1.

[0033] In the method, the guide device 2 is then removed to release the second longitudinal end 1.2 of the strip 1 from the guide device 2 and, since the second part 3.2 of the battery 3 is supported on the guide section 2.1 of the guide device 2, the second part 3.2 of the battery 3 falls onto the second longitudinal end 1.2 of the strip 1 when the guide device 2 is removed (see Figure 3 , where the strip 1 is depicted separated from the battery 3 for the sake of clarity, as Figure 1 ). Since the second longitudinal end 1.2 is in the desired position (without lateral movement) as a result of the guiding means 2 (the guiding section 2.1 of said guiding means 2), when the battery 3 falls onto the second longitudinal end 1.2, the second longitudinal end 1.2 is correctly positioned relative to the battery 3. Preferably, the strip 1 is on a support surface such that the battery 3 presses the second longitudinal end 1.2 of the strip 1 against said support surface.

[0034] To remove the guide device 2, it is moved longitudinally in a removal direction 2W such that it moves away from the first longitudinal end 1.1 of the strip 1. The guide device 2 is thus moved linearly, making it easier to manipulate and correctly position in the guiding position 2P1.

[0035] Preferably, suction is applied to the items placed on the support surface, in particular the belt 1 and the battery 3, from below, and preferably through a plurality of holes in the support surface (not depicted in the figures). Both the belt 1 and the battery 3 are thereby secured in place. Applying suction allows the second longitudinal end 1.2 of the belt 1 to be secured in the desired position. When the belt 1 is placed in the desired position, there is no guarantee that it was initially positioned correctly, and the suction secures it in the position it was originally placed in (whether or not). The use of this type of guide device 2 is particularly advantageous in those methods in which the belt 1 is wound like a coil and moved in the forward direction of movement A for placing it in the desired position (a section of the coiled belt), as previously described.

[0036] In this method, after the guide means 2 are removed, the battery 3 and the strip 1 are moved together in a longitudinal forward movement direction A opposite to the removal direction 2W, said battery 3 being arranged in the second attachment position 3P2. Thus, the method comprises a production cycle having the following steps (preferably in the order indicated):

[0037] - arranging the belt 1 in the desired position on the support surface and arranging the guide device 2 in a guide position 2P1 at least partially on or above the support surface;

[0038] - placing the battery 3 in the first attachment position 3P1;

[0039] - remove the guide means 2; and

[0040] - Moving the battery 3 and the strip 1 together in a longitudinal forward movement direction A opposite to the removal direction 2W, said battery 3 being arranged in the second attachment position 3P2 .

[0041] Once one manufacturing cycle is finished, a new manufacturing cycle can begin and in this new manufacturing cycle the first longitudinal end 1 . 1 of the strip 1 is arranged on the battery 3 arranged in the second attachment position 3P2 after the previous manufacturing cycle.

[0042] After the strip 1 and battery 3 are positioned at the second attachment location 3P2, they are interconnected via an interconnection device (not depicted in the figures). Prior to positioning the battery 3 at the first attachment location 3P1, both faces of the battery 3 are preferably impregnated with an adhesive (also a conductive material), at least in the area where the strip 1 is to be positioned. Due to the adhesive, when the battery 3 contacts the first longitudinal end 1.1 of the strip 1, the first longitudinal end 1.1 adheres to the battery 3 and is correctly positioned from the outset (thus, no further action is required to position it, as occurs with the second longitudinal end 1.2). Furthermore, when the battery 3 contacts the second longitudinal end 1.2 of the strip 1, the second longitudinal end 1.2 adheres to the battery 3 (due to the guiding device 2). The first longitudinal end 1.1 contacts one face of the battery 3, and the second longitudinal end 1.2 contacts the other face of the battery 3. The interconnection device secures this adhesion by hardening it (e.g., by heating), thereby interconnecting the strip 1 and battery 3. This interconnection can be performed, for example, once the strip 1 has been positioned in the desired position during the manufacturing cycle.

[0043] Alternatively, the band 1 and the battery 3 can be transferred from the second attachment position 3P2 to a third attachment position (not depicted in the drawings), where they are in the position for performing interconnection. In this case, once a new battery 3 has been transferred to the third attachment position, interconnection is performed.

[0044] A second aspect of the present invention relates to an apparatus for arranging ribbons and solar cells. The apparatus comprises a first conveyor device (not depicted in the figures) configured to arrange at least one ribbon 1 of a given length having a first longitudinal end 1.1 and an opposite second longitudinal end 1.2 in a desired position, such that the ribbon 1 extends longitudinally. The first conveyor device may comprise, for example, a robotic arm or another conventional conveyor device, and is configured to arrange the ribbon 1 on a support surface (preferably a conveyor belt 4).

[0045] The tape 1 is preferably produced from a coil (a wire wound like a coil), and to arrange it in the desired position, a first conveyor is configured to grasp the free end of the coil and move it longitudinally in a forward movement direction A until a section of a given length, equal to the given length of the tape 1, is arranged in the desired position. This section is the tape 1. In this case, the apparatus also includes a cutting tool (not depicted in the figures) for cutting this section and separating it from the rest of the coil, so that the cut section is the tape 1 and includes the two longitudinal ends 1.1 and 1.2 described. The first longitudinal end 1.1 is the free end of the coil previously grasped by the first conveyor. The cutting tool can be integrated into the first conveyor.

[0046] The apparatus further comprises a guide device 2 having a guide section 2.1, as described with respect to the first aspect of the invention. When the guide device 2 is in the guiding position 2P1 and the belt 1 (and, where appropriate, the corresponding section described in the preceding paragraph) is arranged in the desired position, the guide section 2.1 is configured to accommodate the second longitudinal end 1.2 of the belt 1. To this end, the guide section 2.1 comprises a longitudinal slot 2.0 or groove for each belt 1 arranged in the desired position. When the guide device 2 laterally guides the second longitudinal end 1.2 of the belt 1, the second longitudinal end 1.2 of the belt 1 is arranged or accommodated in the slot 2.0, the guide device 2 thus accommodating the second longitudinal end 1.2 and thus cooperating with the second longitudinal end 1.2. By this cooperation, the guide device 2 laterally guides the second longitudinal end 1.2, thereby preventing lateral movement of the second longitudinal end 1.2 (the walls or surfaces defining the slot 2.0 preventing such lateral movement). When in the guiding position 2P1, the guide section 2.1 is at least partially arranged on or above a support surface (preferably, the conveyor belt 4).

[0047] The apparatus further comprises a second conveying device (not depicted in the drawings) configured to place the battery 3 in the first attachment position 3P1 when the belt 1 is in the desired position and the guide device 2 is in the guide position 2P1, so that when the battery 3 is in the first position 3P1, the first portion 3.1 of the battery 3 is placed on the belt 1 (in contact with the belt 1) and the second portion 3.2 of the battery 3 is placed on the guide device 2 (out of contact with the belt 1). The second conveying device may comprise, for example, a robotic arm or another conventional conveying device.

[0048] The apparatus further comprises a third conveying device (not depicted in the drawings) configured to longitudinally move the guiding device 2 from the guiding position 2P1 to the removal position 2PW in the removal direction 2W (and in the opposite direction from the removal position 2W to the guiding position 2P1). Figure 3 As shown by way of example in FIG, the removal position 2PW is a position other than the guide position 2P1 and in which the guide means 2 do not cooperate with the second longitudinal end 1.2. The third conveying means may comprise, for example, a robotic arm or another conventional conveying means. Figure 3 For clarity and as Figure 1 In the illustration, the guide means 2 and the batteries 3 are arranged separate from the conveyor belt 4, but in practice they will preferably be arranged at the same level as the conveyor belt 4 (like the parts of the belt 1 not over any batteries 3).

[0049] The device further comprises a control device (not depicted in the figures) configured to control the actuation of all the conveyor devices, including the first, second and third conveyor devices (and when generating said actuation), and which may comprise, for example, a controller, a microprocessor, an FPGA or any device with computing capabilities. The control device is thus configured to cause the second conveyor device to place the battery 3 in the first attachment position 3P1 when the belt 1 is in the desired position and the guide device 2 is in the guide position 2P1, and once the first conveyor device has placed the battery 3 on said guide device 2, to cause the third conveyor device to move the guide device 2 from the guide position 2P1 to the removal position PW.

[0050] The device comprises a fourth conveyor device configured to move the belt 1 together with the batteries 3 arranged on the belt 1 in a longitudinal forward movement direction A opposite to the removal direction 2W until the batteries 3 are arranged in the second attachment position 3P2, as described above with respect to the first aspect of the invention. The control device is further configured to control the activation of the fourth conveyor device, once the guide device 2 has been removed from the guide position 2P1 and the batteries 3 have fallen onto the belt 1, the control device being configured to move the belt 1 together with the batteries 3 arranged on the belt 1 in the forward movement direction A.

[0051] The fourth conveying device preferably comprises a conveyor belt 4, said conveyor belt 4 comprising a support surface, the belt 1 being arranged at a desired position on the support surface and the guide device 2 being at least partially arranged on or above the support surface. The first conveying device is configured to arrange the belt 1 on the conveyor belt 4. The device preferably comprises a suction device arranged below the support surface (e.g., conveyor belt 4), and the support surface (e.g., conveyor belt 4) comprises a plurality of holes (not depicted in the drawings), through which the suction device generates a suction force on the object arranged on the support surface (e.g., conveyor belt 4), and the belt 1 and the battery 3 arranged on the support surface (e.g., conveyor belt 4) are fixed in place by means of the suction force, as described with respect to the first aspect of the present invention.

[0052] In addition to the guide section 2.1, the guide device 2 also includes a main section 2.2. The main section 2.2 lies in a first plane, which is at a higher level than a second plane, the plane in which the strip 1 is positioned in the desired position. The guide section 2.0 serves as a transition between the first and second planes. To this end, the guide section 2.1 can define different configurations, such as a straight configuration or a curved configuration defining a given angle relative to the first plane. The second conveying device is configured to position the second portion 3.2 of the battery 3 on the guide section 2.1 while the battery 3 is being positioned in the first position 3P1.
