Description
Technical Field
[0001] The utility model relates to the field of photovoltaic module manufacturing, in particular to a pressure prevention component for a photovoltaic module. Background Art
[0002] In the production and manufacturing process of a photovoltaic module, after the production and manufacturing of battery chips are completed and the battery strings are welded, it is necessary to stack a glass plate, a front encapsulant film, a battery string, a rear encapsulant film, and a back plate (or a glass plate) in sequence, that is, to form a photovoltaic module to be laminated; the photovoltaic module to be laminated is conveyed to a laminator through a laminating cloth, and the laminator can laminate the photovoltaic module to be laminated into an integrated structure.
[0003] However, in the actual lamination process, the pressure borne by the edge part of the photovoltaic module is often greater than that borne by the middle area of the photovoltaic module, which also causes problems such as battery chip cracking, encapsulant film not melting, or air bubbles in the photovoltaic module due to uneven stress. Therefore, before laminating the photovoltaic module, it is necessary to set pressure prevention frames around the photovoltaic module to be laminated, so as to avoid the problem of excessive pressure on the edge of the photovoltaic module to a certain extent; but this also requires dedicated staff to set pressure prevention frames for the photovoltaic module on the production line of the photovoltaic module, and it is also necessary to configure staff to remove the pressure prevention frames after the photovoltaic module is laminated; although the operation difficulty is not great, it is extremely laborious for the staff, and once the manual pressure prevention frame is set incorrectly, it is also easy to cause problems with poor lamination of the photovoltaic module. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a pressure prevention component for a photovoltaic module, which can reduce the manual workload during the lamination process of the photovoltaic module on the basis of avoiding poor lamination of the photovoltaic module.
[0005] To solve the above technical problems, the utility model provides a pressure prevention component for a photovoltaic module, including: a pressure prevention bar; a driving component connecting the pressure prevention bar and the side wall of the laminator cavity;
[0006] The driving component is used to drive the pressure prevention bar to move to a set intermediate area fitting the surface of the laminating cloth, so that the pressure prevention bar is located outside the edge of the photovoltaic module to be laminated on the laminating cloth, or to remove the pressure prevention bar from the set intermediate area on the surface of the laminating cloth.
[0007] In an optional embodiment of the present application, the driving component includes a telescopic structure with one end connected to the side wall of the laminator cavity and the other end connected to the pressure prevention bar;
[0008] The telescopic structure can be telescopically movable in a direction perpendicular to the side wall of the laminator cavity to drive the anti-pressure baffle to move to the side position of the photovoltaic component to be laminated on the laminating cloth, or drive the anti-pressure baffle to retract from the laminating cloth.
[0009] In an optional embodiment of the present application, the telescopic structure includes at least two telescopic cylinders arranged parallel to each other, and a telescopic rod connected to the telescopic cylinders.
[0010] In an optional embodiment of the present application, a height of a side where the anti-compression baffle is connected to the telescopic rod is higher than a height of a side away from the telescopic rod.
[0011] In an optional embodiment of the present application, the anti-pressure baffle has an L-shaped cross-section; and the height of the side where the anti-pressure baffle is connected to the telescopic rod is 20mm-30mm; the height of the anti-pressure baffle away from the telescopic rod is 7.0mm-8.5mm.
[0012] In an optional embodiment of the present application, the anti-pressure baffle is an aluminum baffle or a non-metallic high temperature and wear-resistant baffle.
[0013] In an optional embodiment of the present application, it further comprises a plurality of pairs of anti-pressure strips arranged on the laminated fabric; and the length direction of the anti-pressure strips is perpendicular to the length direction of the laminated fabric;
[0014] The difference between the distance between each pair of two anti-pressure strips and the total width of a group of photovoltaic modules to be laminated is equal to 10 mm-24 mm.
[0015] In an optional embodiment of the present application, the anti-pressure strip has a height of 7.0 mm-9.5 mm and a width of 10.0 mm-15.0 mm.
[0016] In an optional embodiment of the present application, the anti-pressure baffle includes two U-shaped anti-pressure baffles; each of the U-shaped anti-pressure baffles is connected to the side walls on opposite sides of the laminator cavity through the driving assembly;
[0017] When the driving assembly drives the two U-shaped anti-pressure baffles to move to fit the surface of the laminated cloth, the two U-shaped anti-pressure baffles form a rectangular frame structure surrounding the photovoltaic assembly to be laminated.
[0018] In an optional embodiment of the present application, the driving assembly includes a driving motor and an intermediate connecting member;
[0019] The U-shaped anti-pressure barrier strip is connected to the driving motor via the intermediate connecting piece;
[0020] The driving motor is used to drive the two U-shaped pressure protection bars to move up and down in the vertical direction.
[0021] A pressure protection component for a photovoltaic module provided by the present utility model includes a pressure protection bar; a driving component connecting the pressure protection bar and the side wall of the laminator cavity; the driving component is used to drive the pressure protection bar to move actively to a set intermediate area that fits the surface of the laminating cloth, so that the pressure protection bar is located outside the edge of the photovoltaic module to be laminated on the laminating cloth, or to remove the pressure protection bar from the set intermediate area on the surface of the laminating cloth.
[0022] In this application, a driving component and a pressure protection bar are provided on the side wall of the laminator cavity, and the driving component can drive the pressure protection bar to move to the set intermediate area on the laminating cloth or remove the pressure protection bar from the set intermediate area on the laminating cloth; thus, when actually laminating the photovoltaic module to be laminated, when the photovoltaic module to be laminated moves into the laminator cavity along with the laminating cloth, the driving component can drive the pressure protection bar to move to the set intermediate area on the laminating cloth, so that the pressure protection bar is located outside the edge of the photovoltaic module to be laminated, so that the pressure protection bar can avoid the problem that the edge of the photovoltaic module is over-pressed and thus the lamination is poor; and when the photovoltaic module to be laminated is laminated, the driving component can drive the pressure protection bar to be removed from the set intermediate area on the laminating cloth, so as to avoid affecting the removal of the laminated photovoltaic module from the laminator cavity. It can be seen that in this application, on the basis of avoiding poor lamination of the photovoltaic module during the lamination process, there is no need to specially allocate staff to set up a pressure protection frame, which greatly reduces the labor cost of the staff; and it avoids the problem of poor lamination caused by human error. Description of the Drawings
[0023] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0028] In the drawings: 1 is the pressure - resistant bar, 11 is the U - shaped pressure - resistant bar, 2 is the driving assembly, 21 is the telescopic cylinder, 22 is the telescopic rod, 23 is the intermediate connector, 24 is the driving motor, 3 is the photovoltaic module to be laminated, 4 is the laminator cavity, 5 is the laminating cloth, and 6 is the pressure - resistant strip. Detailed implementation manners
[0029] In the laminator equipment, there is a laminating cloth for carrying and conveying the photovoltaic module, and a laminator cavity for laminating the photovoltaic module. The way the laminating cloth conveys the photovoltaic module is similar to the conveying way of a conveyor belt, and the laminating cloth passes through the laminator cavity. Thus, before the photovoltaic module is conveyed to the laminator, a pressure - resistant frame can be placed around the photovoltaic module on the laminating cloth. When the laminating cloth conveys the photovoltaic module and the pressure - resistant frame together into the laminator cavity, the pressing structure in the laminator cavity can apply high pressure to the photovoltaic module on the laminating cloth to achieve the lamination of the photovoltaic module. After the lamination of the photovoltaic module is completed, the laminating cloth conveys the photovoltaic module out of the laminator cavity. At this time, both the pressure - resistant frame and the photovoltaic module can be removed from the laminating cloth.
[0030] In the present application, considering that manually taking and placing the pressure - resistant frame requires a large amount of manual labor, and once an error occurs in manually taking and placing the pressure - resistant frame, it is also easy to cause problems of poor lamination of the photovoltaic module. Therefore, a pressure - resistant bar that can move automatically through the driving assembly is directly set on the side wall of the laminator cavity. When the photovoltaic module needs to be laminated and enters the laminator cavity, it can automatically move to the peripheral edge position of the photovoltaic module, and after the lamination of the photovoltaic module is completed, it can automatically move away without affecting the removal of the photovoltaic module from the laminator cavity. Throughout the process, no manual operation by the staff is required, which greatly reduces the manual labor in the lamination process of the photovoltaic module and also avoids the problem of poor lamination caused by human errors.
[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] As Figures 1 to 2 shown, Figure 1 is the structural schematic diagram of the pressure - resistant assembly of the photovoltaic module provided by the embodiment of the present application; Figure 2 is the structural schematic diagram of the pressure - resistant bar provided by the embodiment of the present application.
[0033] In a specific embodiment of the present application, the pressure prevention component of the photovoltaic module may include:
[0034] A pressure prevention bar 1; A driving component 2 connecting the pressure prevention bar 1 and the side wall of the laminator cavity 4;
[0035] The driving component 2 is used to drive the pressure prevention bar 1 to move actively to fit the set intermediate area on the surface of the laminating cloth 5, so that the pressure prevention bar 1 is located outside the edge of the photovoltaic module 3 to be laminated on the laminating cloth 5, or remove the pressure prevention bar 1 from the set intermediate area on the surface of the laminating cloth 5.
[0036] As Figure 1 shown, in the embodiment shown in Figure 1 shown, the pressure prevention bar 1 is a straight bar-shaped bar; And on the two opposite side walls of the laminator cavity 4 on both sides of the laminating cloth 5, a set of driving components 2 and pressure prevention bars 1 are respectively arranged; And each set of driving components 2 can drive the pressure prevention bar 1 connected thereto to move.
[0037] In practical applications, when the photovoltaic module 3 to be laminated moves into the laminator cavity 4 along with the laminating cloth 5, the driving component 2 can drive the pressure prevention bar 1 to move to the set intermediate area on the laminating cloth 5, and this set intermediate area is also the edge position of the photovoltaic module 3 to be laminated on the laminating cloth 5. When the pressure prevention bar 1 moves to this set intermediate area, it is also located outside the edge position of the photovoltaic module 3 to be laminated. As Figure 1 shown, the two pressure prevention bars 1 are respectively located on the opposite sides of the photovoltaic module 3 to be laminated; And the pressure prevention bar 1 should be parallel to the side edge of the photovoltaic module 3 to be laminated, and be 5 mm - 12 mm away from the side edge of the photovoltaic module 3 to be laminated. In addition, the height of the pressure prevention bar 1 should be slightly greater than the thickness of the photovoltaic module 3 to be laminated. Thus, when the laminator laminates the photovoltaic module 3 to be laminated, the pressure prevention bar 1 can, to a certain extent, avoid problems such as cracking at the edge position of the photovoltaic module 3 to be laminated during lamination; And when the laminator finishes laminating the photovoltaic module 3 to be laminated, the driving component 2 can drive the pressure prevention bar 1 to be removed from the laminating cloth 5, that is, move away from the edge position of the laminated photovoltaic module. At this time, the laminating cloth 5 continues to drive the laminated photovoltaic module out of the laminator cavity 4, and the pressure prevention bar 1 will not cause any obstruction to the movement of the laminated photovoltaic module. In this way, the lamination process of the photovoltaic module can be smoothly realized; During the whole process, no manual operation by any staff is required at all. Only the driving component 2 needs to automatically drive the movement of the pressure prevention bar 1, which greatly reduces the workload during the lamination process of the photovoltaic module.
[0038] In addition, since the pressure-resistant strip 1 needs to jointly bear the high temperature and high pressure applied by the laminator together with the photovoltaic module 3 to be laminated, therefore, the pressure-resistant strip 1 in this application can adopt a non-metallic high-temperature and wear-resistant strip. Of course, in order to avoid the excessive weight of the pressure-resistant strip 1, the pressure-resistant strip 1 in this application can also adopt an aluminum strip, and no specific limitation is made in this application in this regard.
[0039] On this basis, there can be multiple different implementation manners for the driving component 2 in this application to drive the pressure-resistant strip 1; in an optional embodiment of this application, the driving component 2 can include:
[0040] A telescopic structure with one end connected to the side wall of the laminator cavity 4 and the other end connected to the pressure-resistant strip 1;
[0041] The telescopic structure can telescopically move along a direction perpendicular to the side wall of the laminator cavity 4 to drive the pressure-resistant strip 1 to move to the side position of the photovoltaic module 3 to be laminated on the laminating cloth 5, or drive the pressure-resistant strip 1 to retract and move from the laminating cloth 5.
[0042] Such as Figure 2 shown, in the Figure 2 embodiment shown, the telescopic direction of the telescopic structure connected to each pressure-resistant strip 1 is perpendicular to the side wall of the laminator cavity 4. Thus, when the telescopic structure extends, it can drive the pressure-resistant strip 1 to move away from the side wall of the laminator cavity 4 and move to a position close to the edge of the photovoltaic module 3 to be laminated; and when the telescopic structure contracts, it can drive the pressure-resistant strip 1 to contract to a position close to the side wall of the laminator cavity 4, and then be removed from the upper surface of the laminating cloth 5, so as to avoid hindering the movement of the photovoltaic module.
[0043] In addition, in an optional implementation manner in this embodiment, the telescopic structure can include at least two telescopic cylinders 21 arranged in parallel with each other, and a telescopic rod 22 connected to the telescopic cylinder 21.
[0044] Referring to Figure 2 , the telescopic structure provided in this embodiment can be a telescopic cylinder 21, and the telescopic cylinder 21 and the pressure-resistant strip 1 are connected by a telescopic rod 22. In actual application, each pressure-resistant strip 1 can be connected to at least two groups of telescopic cylinders 21 and telescopic rods 22; and the two groups of telescopic cylinders 21 and telescopic rods 22 are parallel to each other; the telescopic activities between the two groups of telescopic cylinders 21 should be synchronized. In addition, the telescopic cylinder 21 in this application can be a pneumatic cylinder or a telescopic oil cylinder, and no specific limitation is made in this application in this regard.
[0045] On this basis, the distance by which the telescopic cylinder 21 extends outward can be set with different extension distance parameters of the telescopic cylinder 21 based on the different sizes of the photovoltaic module 3 to be laminated, so as to better adapt to the lamination of photovoltaic modules of different specifications.
[0046] In addition, in order to ensure a stable connection between the anti-pressure baffle 1 and the telescopic rod 22, the portion where the anti-pressure baffle 1 and the telescopic rod 22 are connected to each other cannot be too thin, and based on the lamination requirements of the photovoltaic module 3 to be laminated, the anti-pressure baffle 1 close to the photovoltaic module side cannot be too high; for this reason, in another optional implementation of this embodiment, the anti-pressure baffle 1 can further include:
[0047] The height of the side where the anti-compression baffle bar 1 is connected to the telescopic rod 22 is higher than the height of the side away from the telescopic rod 22 .
[0048] like Figure 2 As shown, in this embodiment, the anti-compression baffle 1 has an L-shaped cross-section; the height of the side where the anti-compression baffle 1 is connected to the telescopic rod 22 can be 20mm-30mm, while the height of the side of the anti-compression baffle 1 away from the telescopic rod 22 can be 7.0mm-8.5mm.
[0049] In practical applications, the cross section of the anti-pressure barrier strip 1 is not necessarily an L-shaped cross section, but can also be a right-angled trapezoidal cross section, that is, the upper surface of the anti-pressure barrier strip 1 is an inclined surface, and the height of the anti-pressure barrier strip 1 gradually decreases from the side close to the telescopic rod 22 to the side away from the telescopic rod 22. Of course, in this embodiment, the anti-pressure barrier strip 1 can also be relatively thick only at the part connected to the telescopic rod 22, and the height of other parts can be set to avoid poor lamination of the photovoltaic module 3 to be laminated, and this is not specifically limited in this application.
[0050] As described above, the anti-pressure baffle 1 is a linear bar structure. As the telescopic structure is extended, the anti-pressure baffle 1 can only be pushed to the outer sides of the photovoltaic assembly 3 to be laminated on both sides, so that the anti-pressure baffle 1 is substantially parallel to the edge of the photovoltaic assembly 3 to be laminated and extends and distributes; in order to further improve the anti-pressure effect on the photovoltaic assembly 3 to be laminated, in another optional embodiment of the present application, the anti-pressure assembly may further include:
[0051] A plurality of pairs of anti-pressure strips 6 are arranged on the laminated cloth 5; and the length direction of the anti-pressure strips 6 is perpendicular to the length direction of the laminated cloth 5;
[0052] The difference between the distance between each pair of two anti-pressure strips 6 and the total width of a group of photovoltaic components 3 to be laminated is equal to 10 mm-24 mm.
[0053] In this embodiment, multiple pairs of pressure-resistant strips 6 can be arranged on the laminating cloth 5 by bonding or other means. When the photovoltaic module 3 to be laminated is arranged on the laminating cloth 5, a set of photovoltaic modules 3 to be laminated can be arranged between each pair of pressure-resistant strips 6 (generally including 5 to 10 photovoltaic modules 3 to be laminated, and the distance between two adjacent photovoltaic modules 3 to be laminated should be 5 mm - 12 mm); it can be understood that the pressure-resistant strip 6 should be perpendicular to the pressure-resistant baffle 1; thus, the pressure-resistant strip 6 can extend along the edges on both sides of a set of photovoltaic modules 3 to be laminated; and, the distance between each pressure-resistant strip 6 and the nearest photovoltaic module 3 to be laminated should be 5 mm - 12 mm; thus, a rectangular frame structure surrounding a set of photovoltaic modules 3 to be laminated can be roughly formed between the pressure-resistant strip 6 and the pressure-resistant baffle 1, realizing all-round pressure protection for the photovoltaic modules 3 to be laminated. In addition, the height of the pressure-resistant strip 6 in this embodiment can be 7.0 mm - 9.5 mm, and the width can be 10.0 mm - 15.0 mm.
[0054] Based on the above discussion, the pressure-resistant baffle 1 in this application is not limited to the straight bar-shaped baffle structure, and the driving assembly 2 is not limited to driving the pressure-resistant baffle 1 in a telescopic driving manner.
[0055] As Figure 3 and Figure 4 shown, in another alternative embodiment of this application, the pressure-resistant assembly can include:
[0056] The pressure-resistant baffle 1 includes two U-shaped pressure-resistant baffles 11; each U-shaped pressure-resistant baffle 11 is respectively connected to the side walls on the opposite sides of the laminator cavity 4 through the driving assembly 2;
[0057] When the driving assembly 2 drives the two U-shaped pressure-resistant baffles 11 to move to fit the surface of the laminating cloth 5, the two U-shaped pressure-resistant baffles 11 form a rectangular frame structure surrounding the photovoltaic module 3 to be laminated.
[0058] As Figure 3 and Figure 4 shown, the pressure-resistant baffle 1 in this embodiment is a U-shaped pressure-resistant baffle 11. Thus, when the two U-shaped pressure-resistant baffles 11 approach each other, a rectangular frame structure can be formed between the two U-shaped pressure-resistant baffles 11, and this rectangular frame structure can just surround the photovoltaic module 3 to be laminated in a circle. Thus, when the photovoltaic module 3 to be laminated is laminated, the two U-shaped pressure-resistant baffles 11 can realize all-round pressure protection for the entire edge of the photovoltaic module 3 to be laminated.
[0059] It can be understood that in practical applications, other structural forms of the pressure-proof strip 1 are not excluded in this application; for example, the pressure-proof strip 1 can be two L-shaped pressure-proof strips 1 that can be spliced into a rectangular frame structure; the pressure-proof strip 1 can also directly adopt a rectangular frame structure, and the two ends of the rectangular frame structure close to the side wall of the laminator cavity 4 are respectively connected to the side wall of the laminator cavity 4 through the driving assembly 2; the technical solution of this application can also be realized, and there are no specific restrictions in this application.
[0060] In addition, in an optional implementation manner of this embodiment, the driving assembly 2 includes a driving motor 24 and an intermediate connector 23; the U-shaped pressure-proof strip 11 is connected to the driving motor 24 through the intermediate connector 23; the driving motor 24 is used to drive the two U-shaped pressure-proof strips 11 to move up and down in the vertical direction.
[0061] The driving assembly 2 in this embodiment can drive the two U-shaped pressure-proof strips 11 to move in a way of driving up and down; thus, when the photovoltaic module 3 to be laminated moves into the laminator cavity 4, the driving assembly 2 can synchronously drive the two U-shaped pressure-proof strips 11 to move downward to the surface of the lifting box laminating cloth 5 and surround the photovoltaic module 3 to be laminated. After the photovoltaic module 3 to be laminated is laminated, the driving assembly 2 can synchronously drive the two U-shaped pressure-proof strips 11 to move upward, so that the photovoltaic module and the U-shaped pressure-proof strip 11 are located at two different height levels, thereby ensuring that the photovoltaic module can be removed with the laminating cloth 5.
[0062] Based on the above discussion, in addition to the above-mentioned telescopic driving and lifting driving methods, the driving assembly 2 in this application can also adopt a flipping driving method (that is, flipping the pressure-proof strip 1 to fit the side wall of the laminator cavity 4) or other driving methods, and there are no specific restrictions in this application.
[0063] In summary, in the present application, a driving component and a pressure-proof bar are provided on the side wall of the laminator cavity, and the driving component can drive the pressure-proof bar to move to a set intermediate area on the laminating cloth or remove the pressure-proof bar from the set intermediate area on the laminating cloth. Thus, when actually laminating a photovoltaic module to be laminated, when the photovoltaic module to be laminated moves into the laminator cavity along with the laminating cloth, the driving component can drive the pressure-proof bar to move to the set intermediate area on the laminating cloth and be located at the edge position of the photovoltaic module to be laminated, so that the pressure-proof bar can prevent the edge of the photovoltaic module from being overly pressed, thereby avoiding the problem of poor lamination. When the photovoltaic module to be laminated is laminated, the driving component can drive the pressure-proof bar to be removed from the set intermediate area on the laminating cloth, thus preventing the laminated photovoltaic module from being affected when it is removed from the laminator cavity. It can be seen that on the basis of avoiding poor lamination of the photovoltaic module during the lamination process of the present application, there is no need to specifically allocate staff to set up a pressure-proof frame, which greatly reduces the labor cost of the staff; and it avoids the problem of poor lamination caused by human error.
