Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, in particular to a lamination tooling for photovoltaic modules. Background Art

[0002] In the processing technology of photovoltaic modules, busbars are usually used. The main function of the busbar is to collect and transmit the current on the battery chips to the output end of the module, realizing the conversion and output of electric energy. It can effectively reduce the path impedance of the current and improve the power generation efficiency of the photovoltaic module. In addition, the busbar can also reasonably shunt the current between the battery chips to ensure that each battery chip can fully play its role and reduce the influence of uneven current distribution on the performance of the whole module. In addition, the structure and material selection of the busbar are also very important. A reasonable busbar structure and excellent materials can improve its durability and corrosion resistance, and reduce the performance degradation caused by long-term use. At present, the inherent reliable performance of the busbar has met the requirements of various photovoltaic modules in the market. However, in the manufacturing process of photovoltaic modules, in addition to pursuing performance, the appearance requirements of the busbar are also particularly important. From the visual perception, the appearance defect of the busbar means that the photovoltaic module is defective; those that do not meet the appearance requirements can be judged as appearance defects. Such photovoltaic modules do not meet the appearance quality requirements, reducing the product yield rate, and at the same time, there is also a risk of rejection by users, increasing costs.

[0003] At present, in the production process of photovoltaic modules, due to the accumulation at the bending position of the lead-out wire of the back glass during the lamination of double-glass photovoltaic modules, it protrudes from the surface of the back glass. At this time, during the process of the lamination cavity pressing down on the photovoltaic module, the lamination cavity transfers the pressure to the adhesive film at the bending position through the busbar, resulting in the adhesive film spreading to the periphery of the busbar or overflowing from the opening of the back glass. This will cause less adhesive film to be filled between the busbar and the front glass, and the busbar is close to the embossed surface of the front glass, resulting in the phenomenon of busbar marks on the appearance of the photovoltaic module, making the overall appearance of the photovoltaic module poor. Among them, the marks generated by the black busbar are particularly serious, resulting in poor appearance of the photovoltaic module, reducing the product yield rate of the photovoltaic module, and increasing costs.

[0004] Therefore, it is urgent to design a lamination tooling for photovoltaic modules to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lamination tooling for photovoltaic modules, which solves the phenomenon of busbar marks on the front of the photovoltaic module, improves the product yield rate of the photovoltaic module, and saves costs.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0009] a spacer block, the spacer block is connected to the frame body, and an opening is provided on one side of the spacer block facing the photovoltaic module. The opening is used to be correspondingly arranged with an opening on the back glass of the photovoltaic module to be laminated.

[0010] As an alternative technical solution of the lamination tooling for photovoltaic modules, the spacer block includes a base material and a coating layer coated outside the base material. The opening penetrates through the base material and the coating layer; the base material includes a flexible member, and the coating layer includes a polymer member.

The lamination tooling for photovoltaic modules includes a second connecting belt, and two adjacent spacer blocks are connected through the second connecting belt.

[0014] As an alternative technical solution of the lamination tooling for photovoltaic modules, the first connecting belt and the second connecting belt are collinearly arranged.

[0015] As an alternative technical solution of the lamination tooling for photovoltaic modules, the lamination tooling for photovoltaic modules includes a third connecting belt and a fourth connecting belt. One end of the third connecting belt is connected to the spacer block, and the other end is connected to the fourth connecting belt. Two ends of the fourth connecting belt are respectively connected to opposite sides of the frame body.

[0016] As an alternative technical solution of the lamination tooling for photovoltaic modules, the third connecting belt is perpendicular to the first connecting belt, and the fourth connecting belt is parallel to the first connecting belt.

[0017] As an alternative technical solution of the lamination tooling for photovoltaic modules, the materials of the first connecting belt, the second connecting belt, the third connecting belt, and the fourth connecting belt are all Teflon.

[0018] As an alternative technical solution of the lamination tooling for photovoltaic modules, the lamination tooling for photovoltaic modules further includes a reinforcing rib.

[0019] The beneficial effects of the present utility model at least include:

[0020] The present utility model provides a lamination tooling for photovoltaic modules, which is used for laminating photovoltaic modules. The lamination tooling for photovoltaic modules includes a frame body and a cushion block. Among them, the cushion block is connected to the frame body, and an opening is provided on the side of the cushion block facing the photovoltaic module. The opening is used to be correspondingly arranged with the opening on the back glass of the photovoltaic module to be laminated. When the laminator laminates the photovoltaic module, the upper cavity of the laminator can be in contact with and extrude the photovoltaic module and the cushion block at the same time. Since the opening on the cushion block is directly opposite to the opening on the back glass, the setting of the opening can avoid the direct pressure on the bent part of the bus bar. In this way, during the lamination process of the upper cavity of the laminator, the upper cavity of the laminator can be in contact with the cushion block and apply pressure to the cushion block, rather than directly contacting and applying pressure to the bus bar. That is to say, the upper cavity of the laminator will not squeeze the bus bar, thereby avoiding the extrusion of the adhesive film pasted to the front glass by the bent part of the bus bar, and further avoiding the appearance defect that the bent part of the bus bar is close to or in contact with the front glass and a bus bar mark appears on the front glass. It solves the problem of the appearance of bus bar marks on the front of the photovoltaic module, improves the product yield of the photovoltaic module, and saves costs. Description of the Drawings

[0040] As Figure 1 shown, when the photovoltaic module 10 is stacked and waiting for lamination, at this time, the bent portion of the bus bar at the opening 11 is located between two layers of encapsulant films 14. Figure 1 The position indicated by A in

[0041] As Figure 2 shown, when the upper cavity 20 of the laminator presses down, since the height of the bus bar 12 is higher than the height of the back glass 15, therefore, the upper cavity 20 of the laminator directly contacts and applies pressure to the bus bar 12. At this time, under the pressure of the upper cavity 20 of the laminator pressing down, the encapsulant film 14 between the bent portion of the bus bar and the front glass 13 is extruded, which will cause less filling of the encapsulant film 14 between the bus bar 12 and the front glass 13. The bus bar 12 is close to the embossed surface of the front glass 13, thus resulting in the phenomenon of the imprint of the bus bar 12 on the appearance of the photovoltaic module 10, making the overall appearance of the photovoltaic module 10 poor. Among them, the imprint generated by the black bus bar 12 is particularly serious, causing poor appearance of the photovoltaic module 10, reducing the product yield of the photovoltaic module 10, and increasing the cost. Among them, Figure 2 The position indicated by B in

[0042] To solve the above technical problems, this embodiment provides a laminating tooling for photovoltaic modules, which solves the problem of the appearance of bus bar marks on the front side of the photovoltaic module 10, improves the product yield of the photovoltaic module 10, and saves costs.

[0043] As Figures 3 - 6 shown, this laminating tooling for photovoltaic modules is used to laminate the photovoltaic module 10. The laminating tooling for photovoltaic modules mainly includes a frame body 100 and a spacer block 200. Among them, the spacer block 200 is connected to the frame body 100. An opening 210 is provided on the side of the spacer block 200 facing the photovoltaic module 10. The opening 210 is used to be correspondingly arranged with the opening 11 on the back glass 15 of the photovoltaic module 10 to be laminated. When the laminator laminates the photovoltaic module 10, the upper cavity 20 of the laminator can be in contact with and squeeze the photovoltaic module 10 and the spacer block 200 at the same time. Since the opening 210 on the spacer block 200 is directly opposite to the opening 11 of the back glass 15, the setting of the opening 210 can prevent the bent part of the bus bar from being directly pressed. In this way, during the lamination process of the upper cavity 20 of the laminator, the upper cavity 20 of the laminator can be in contact with the spacer block 200 and exert pressure on the spacer block 200, rather than directly contacting and exerting pressure on the bus bar 12. That is to say, the upper cavity 20 of the laminator will not squeeze the bus bar 12, thereby avoiding the extrusion of the adhesive film 14 adhered to the front glass 13 by the bent part of the bus bar, and further avoiding the appearance of the bad appearance phenomenon that the bent part of the bus bar is close to or in contact with the front glass 13 and leaving bus bar marks on the front glass 13. Solve the problem of the appearance of bus bar marks on the front side of the photovoltaic module 10, improve the product yield of the photovoltaic module 10, and save costs.

[0044] In addition, the opening 210 on the spacer block 200 can also accommodate the adhesive film 14 overflowing from the opening 11 on the back glass 15 of the photovoltaic module 10 during the lamination process. That is to say, the opening 210 can also leave an overflow space for the opening 11, avoiding the adhesion of the adhesive film 14 overflowing during the lamination process of the photovoltaic module 10 to the spacer block 200, which is beneficial to the disassembly of the laminating tooling for photovoltaic modules and the photovoltaic module 10 after the lamination process, and improves work efficiency.

[0045] It should be noted that the photovoltaic module 10 in this embodiment refers to a double-glass photovoltaic module. The upper cavity 20 of the laminator is made of a flexible material such as rubber. During the lamination process, the upper cavity 20 of the laminator can deform, so that the upper cavity 20 of the laminator can be in full contact with the spacer block 200 and the back glass 15 of the photovoltaic module 10, improving the uniformity of the force on the photovoltaic module 10.

[0046] Exemplarily, the opening 210 in this embodiment can be set as a through hole penetrating through the opposite two sides of the spacer block 200, or can also be set in the form of a blind hole or other structures.

[0047] In some embodiments, the spacer 200 includes a base material and a coating layer coated outside the base material. The opening 210 can penetrate through the base material and the coating layer; the base material includes a flexible member, and the coating layer includes a polymer member. The setting of the coating layer can play a certain protective role for the base material, prevent the miscellaneous substances in the base material from falling off, and improve the integrity and reliability of the spacer 200. The base material is made of a flexible material, so that it can protect the back glass 15 of the photovoltaic module 10 and avoid scratching or even bursting the back glass 15.

[0048] Exemplarily, the base material can be processed from a high-temperature resistant silicone material, that is, the flexible member can be made of silicone material. The coating layer can be processed from a high-temperature resistant Teflon material, that is, the polymer member can be made of Teflon material.

[0049] In this embodiment, the opening 210 is coaxially arranged with the spacer 200. On the one hand, it can ensure that the bus bar 12 is located in the opening 210 as much as possible, avoiding the direct contact and pressure of the upper cavity 20 of the laminator on the bus bar 12; on the other hand, it can avoid the adhesive film 14 overflowing from the opening 11 from adhering to the spacer 200 as much as possible, and improve the disassembly efficiency of the photovoltaic module 10 and the photovoltaic module laminating tooling after the laminating process.

[0050] Optionally, the opening 210 in this embodiment can be set to types such as circular holes, square holes, triangular holes, etc., which will not be elaborated here one by one.

[0051] Optionally, the thickness of the spacer 200 in this embodiment can be set to 3.5 mm ± 1.5 mm, the side length of the spacer 200 can be set to 150 mm ± 50 mm, and when the opening 210 is a square hole, the opening 210 can be set to 50 mm ± 10 mm. Of course, the operator can also flexibly set the sizes of the spacer 200 and the opening 210 according to actual needs, which will not be elaborated here one by one.

[0052] As Figure 3 shown, the photovoltaic module laminating tooling in this embodiment includes a first connecting band 300, and the spacer 200 is connected to the frame 100 through the first connecting band 300. The setting of the first connecting band 300 can improve the convenience and stability of the connection between the spacer 200 and the frame 100. In addition, both ends of the first connecting band 300 can be detachably connected to the frame 100 and the spacer 200 respectively by means of clamping or bolt connection, which is convenient for the later replacement and maintenance of the spacer 200 and the first connecting band 300, and prolongs the service life of the photovoltaic module laminating tooling.

[0053] Further, a plurality of cushion blocks 200 are provided in this embodiment. The photovoltaic module lamination tooling includes a second connecting band 400. Adjacent two cushion blocks 200 are connected by the second connecting band 400. A plurality of openings 11 are provided on the back glass 15 of the photovoltaic module 10, and the number of the openings 11 is the same as that of the cushion blocks 200, which can improve the flexible applicability of the photovoltaic module lamination tooling. The setting of the second connecting band 400 can play a certain fixing role on adjacent two cushion blocks 200, avoid the phenomenon that adjacent two cushion blocks 200 have relative displacement, and improve the product yield of the photovoltaic module 10.

[0054] Furthermore, the first connecting band 300 and the second connecting band 400 in this embodiment are arranged collinearly, which can ensure that adjacent two cushion blocks 200 are kept in a straight line, so that the openings 210 on all the cushion blocks 200 can be arranged directly opposite to the openings 11 on the back glass 15.

[0055] As Figure 3 shown, in this embodiment, the photovoltaic module lamination tooling includes a third connecting band 500 and a fourth connecting band 600. One end of the third connecting band 500 is connected to the cushion block 200, and the other end is connected to the fourth connecting band 600. Both ends of the fourth connecting band 600 are respectively connected to opposite sides of the frame body 100. The third connecting band 500 is perpendicular to the first connecting band 300, and the fourth connecting band 600 is parallel to the first connecting band 300. This can improve the fixing effect on the cushion block 200, reduce the shaking of the cushion block 200 during use, and improve the stability and reliability of the photovoltaic module lamination tooling.

[0056] It should be noted that the numbers of the first connecting band 300, the second connecting band 400, the third connecting band 500 and the fourth connecting band 600 in this embodiment are not limited. The operator can flexibly set their numbers according to the specific actual situation to ensure the restraint effect on the cushion block 200.

[0057] Exemplarily, the materials of the first connecting band 300, the second connecting band 400, the third connecting band 500 and the fourth connecting band 600 in this embodiment are all Teflon. That is to say, the first connecting band 300, the second connecting band 400, the third connecting band 500 and the fourth connecting band 600 are all processed and made of Teflon. Utilizing the heat resistance, non-stickiness and wear resistance of Teflon can improve the service life of the first connecting band 300, the second connecting band 400, the third connecting band 500 and the fourth connecting band 600, and at the same time facilitate the disassembly work of the photovoltaic module 10 and the photovoltaic module lamination tooling after the lamination process, and improve the work efficiency.

[0058] As Figure 3As shown, the photovoltaic module lamination tooling in this embodiment further includes a reinforcing rib 700. Both ends of the reinforcing rib 700 are connected to the frame 100 and enclose a triangular structure with the frame 100. Thus, the stability and reliability of the frame 100 can be improved by utilizing the stable structure of the triangle, and the risk of deformation of the frame 100 can be reduced. At the same time, the setting of the frame 100 can, on the one hand, play a role in fixing and limiting the photovoltaic module 10 to avoid the phenomenon that the photovoltaic module 10 shakes randomly in the laminator; on the other hand, it can absorb and buffer the stress at the four peripheral edges of the photovoltaic module 10 and improve the safety of the photovoltaic module 10.

[0059] The usage method of this photovoltaic module lamination tooling is as follows:

[0060] First, convey the laminated photovoltaic module 10 to the area to be laminated and wait.

[0061] Then, cover this photovoltaic module lamination tooling on the photovoltaic module 10 and ensure that the opening 210 on the spacer 200 is directly opposite to the opening 11 on the back glass 15. At this time, the first connecting band 300, the second connecting band 400, the third connecting band 500, and the fourth connecting band 600 are all above the back glass 15.

[0062] Then, convey the photovoltaic module 10 and this photovoltaic module lamination tooling together into the laminator for the lamination process.

[0063] Finally, after the lamination process is completed, wait for the frame 100 of this photovoltaic module lamination tooling to cool down, then remove this photovoltaic module lamination tooling, and convey the photovoltaic module 10 to the next process section for further processing.
