Description

Technical Field

[0001] The utility model relates to the technical field of solar cell preparation, and particularly relates to a photovoltaic module framing tooling and a photovoltaic module with the same. Background Art

[0002] The solar cells that have been put into application usually consist of a photovoltaic module panel in the middle and a photovoltaic module frame arranged around the panel. There are three main surfaces of the photovoltaic module frame. As Figure 1 shown, among them, surface A is the side against the frame slot, and this surface cooperates with the front surface of the panel; surface B is the side where the photovoltaic module frame cooperates with the side of the photovoltaic module, and it belongs to the decorative surface; surface C is the side where the photovoltaic module frame cooperates with the back surface of the panel and is against the backplane in the panel. When connecting, the frame and the panel are adhered together by using adhesive silicone.

[0003] The difference between the composition structure of the full-screen photovoltaic module and the conventional photovoltaic module is that, as Figure 2 shown, the component frame of the full-screen module has no surface A, so that the front surface of the panel in the assembled photovoltaic module can be completely exposed. The full-screen photovoltaic module is not only beautiful but also can increase the effective area of the photovoltaic module receiving sunlight and improve the efficiency of the photovoltaic module.

[0004] However, during the normal production of the full-screen photovoltaic module, as Figure 3 shown, when framing the module, the panel and the frame slot face downward, and the adhesive silicone between the panel and the frame is not cured. Due to the lack of positioning between the panel and the frame, under the action of the gravity of the laminate, the framed module is prone to separation and falling off during the conveying process. Summary of the Utility Model

[0005] In view of this, the utility model provides a photovoltaic module framing tooling and a photovoltaic module with the same to solve the problem that the panel and the frame are prone to falling off during the conveying process after the full-screen photovoltaic module is framed.

[0006] In the first aspect, the utility model provides a photovoltaic module framing tooling, including:

[0007] Clamping members, there are a pair of them, the pair of clamping members are arranged facing each other, and the two side edges on one side of the pair of clamping members are fixedly connected. The surfaces of the pair of clamping members facing each other are adapted to cooperate and abut against the C surface of the component frame or the front surface of the panel laminate.

[0008] When a full-screen photovoltaic module is framed, the edge of the backplane glass side of the panel laminate is closely attached to the inner wall of the B side of the frame without the A side through a glass groove. The glue-applied plane between the backplane glass of the panel laminate and the inner wall of the frame is closely attached. A special photovoltaic bonding silicone is applied between the glue-applied plane and the backplane glass of the panel laminate. The bonding silicone fully fills the gap between the panel laminate and the glue-applied plane of the frame to ensure full overflow of the glue. Then, a photovoltaic module framing tooling is clamped on the four sides of the full-screen photovoltaic module composed of the panel laminate and the module frame. The inner side of one clamping piece is in mating contact with the C side of the module frame, and the inner side of the other clamping piece is in fitting contact with the surface of the front glass of the panel laminate. Multiple photovoltaic module framing toolings are used to clamp and fix the four sides of the full-screen module. After the full-screen photovoltaic module is framed, a framing tooling is installed on the full-screen photovoltaic module. The framing tooling can firmly fix the panel laminate and the frame, and the panel laminate will not shake during the conveying process, ensuring that the panel laminate will not come out from the side of the frame without the A side, improving the yield of the photovoltaic module. Adding a framing tooling to the full-screen photovoltaic module enables the framed full-screen photovoltaic module to be conveyed on the assembly line, realizing batch and continuous production; moreover, the framed full-screen photovoltaic modules with the framing tooling can be stacked on top of each other. The framing tooling can prevent glue overflow at the side without the A side of the frame, avoiding sticking adjacent two full-screen photovoltaic modules together, saving the space utilization rate of the curing workshop, and improving the production efficiency. The framing tooling cooperates with the photovoltaic module by clamping, is convenient to disassemble and assemble, and can be reused.

[0009] In an alternative embodiment, it further includes a connecting piece, and a pair of clamping pieces are respectively fixedly installed at opposite ends of the connecting piece. By fixedly connecting the pair of clamping pieces through the connecting piece, the stability between the clamping pieces is improved, and the thickness of the photovoltaic module that can be clamped between the pair of clamping pieces is increased.

[0010] In an alternative embodiment, a transition fillet is provided between the clamping piece and the connecting piece.

[0011] In an alternative embodiment, the clamping piece extends in an arc shape towards the end away from the connection of the clamping pieces, and the convex surfaces of the pair of clamping pieces face each other. The convex part of the clamping piece is matched with the photovoltaic module, reducing the contact area between the clamping piece and the photovoltaic module, and preventing damage to the photovoltaic module when relative movement occurs between the clamping piece and the photovoltaic module.

[0012] In an alternative embodiment, an elastic buffer is connected to the opposite surface of the clamping piece. The elastic buffer is used to buffer the clamping force of the clamping piece on the photovoltaic module, avoiding damage to the photovoltaic module by the clamping piece.

[0013] In an optional embodiment, the elastic buffer is a rubber buffer pad, a polyurethane buffer pad, a foam plastic buffer pad, an elastic sponge pad, an elastic fiber buffer pad, an elastic clay plate or a spring sheet.

[0014] In an optional embodiment, the clamping member is a clamping plate or a clamping rod or a clamping frame.

[0015] In an optional embodiment, a clamping piece is fixedly connected to the side of the clamping piece facing away from each other, and the clamping piece and the clamping piece are combined to form a clamping hole. When installing the frame assembly tool on the photovoltaic module, the external device clamping claw can be inserted into the clamping hole, and a pair of clamping pieces are clamped on the photovoltaic module after being opened by the external device clamping claw, so as to realize the automation of the photovoltaic module assembly process.

[0016] In an optional embodiment, the sides of a pair of clamps facing away from the clamps are parallel to each other. After the framing tooling is installed on all four sides of the photovoltaic module, multiple photovoltaic modules with framing tooling can be stacked, and the clamps are used to abut each other back to back, so that multiple layers of photovoltaic modules can be stacked horizontally, thereby improving the stability of the stacked photovoltaic modules during transportation.

[0017] In a second aspect, the utility model further provides a photovoltaic module, including the photovoltaic module frame assembly tooling of the utility model. Because the photovoltaic module includes the photovoltaic module frame assembly tooling, it has the same effect as the photovoltaic module frame assembly tooling, and will not be described in detail here.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Below in conjunction with Figures 4 to 6 , describe the embodiments of the present utility model.

[0032] According to an embodiment of the present utility model, on the one hand, a photovoltaic module framing tooling is provided, including a pair of clamping members 1. The photovoltaic module framing tooling provided in this embodiment can be installed on the four sides of a full-screen photovoltaic module such as an aluminum frame, a steel frame, and a composite frame, or can be installed on the four sides of a conventional photovoltaic module with an A-side frame.

[0033] The pair of clamping members 1 are arranged facing each other, and two side edges on one side of the pair of clamping members 1 are fixedly connected. The surfaces of the pair of clamping members 1 facing each other are adapted to cooperate and abut against the C surface of the module frame 7 or the front surface of the encapsulated cell panel 8.

[0034] When the full-screen photovoltaic module is framed, the edge of the back glass of the panel laminate 8 is closely attached to the inner wall of the B side of the frame without the A side through a glass groove. The glue-applying plane between the back glass of the panel laminate 8 and the inner wall of the frame is closely attached. A special photovoltaic bonding silicone is applied between the glue-applying plane and the back glass of the panel laminate 8. The bonding silicone fully fills the gap between the panel laminate 8 and the glue-applying plane of the frame to ensure full overflow of the glue. Before the laminate and the frame are framed, a special bonding silicone is applied to the glue-applying plane area of the frame, and the glue-applying thickness is 3-5 mm. Then, the photovoltaic module framing tooling is clamped on the four sides of the full-screen photovoltaic module composed of the panel laminate 8 and the module frame 7. The inner side of one clamping member 1 is in mating contact with the C side of the module frame 7, and the inner side of the other clamping member 1 is in fitting contact with the front glass surface of the panel laminate 8. The four sides of the full-screen module are clamped and fixed by multiple photovoltaic module framing toolings.

[0035] After the full-screen photovoltaic module is framed, a framing tooling is installed on the full-screen photovoltaic module. The framing tooling can firmly fix between the panel laminate 8 and the frame. The panel laminate 8 will not shake during the conveying process, ensuring that the panel laminate 8 will not fall off from the side of the frame without the A side, improving the yield of the photovoltaic module. Adding a framing tooling to the full-screen photovoltaic module enables the full-screen photovoltaic module to be conveyed on the assembly line after being framed, realizing batch continuous production; moreover, the full-screen photovoltaic modules with the framing tooling can be stacked on top of each other after being framed. The framing tooling can prevent the glue from overflowing at the place without the A side of the frame, avoiding sticking adjacent two full-screen photovoltaic modules together, saving the space utilization rate of the curing workshop and improving the production efficiency. The framing tooling cooperates with the photovoltaic module in a clamping manner, which is convenient for disassembly and assembly and can be reused.

[0036] In one embodiment, it further includes a connecting member 2. A pair of clamping members 1 are respectively fixedly installed at the opposite ends of the connecting member 2. Among them, the connecting member 2 can be a connecting plate, a connecting column or a connecting frame fixedly connected between a pair of clamping members 1. In this embodiment, in order to ensure the stability between a pair of clamping members 1 and for the convenience of manufacturing, the connecting member 2 is selected as a connecting plate, and the connecting member 2 and a pair of clamping members 1 are integrally formed members. By fixedly connecting a pair of clamping members 1 through the connecting member 2, the stability between the clamping members 1 is improved, and the thickness of the photovoltaic module that can be clamped between a pair of clamping members 1 is increased.

[0037] In one embodiment, the clamping member 1 is a clamping plate, a clamping rod or a clamping frame. In this embodiment, the clamping member 1 is selected as a clamping plate, and the clamping plate and the connecting plate are integrally formed by stamping. A transition fillet 3 formed during the stamping process is reserved between the clamping plate and the connecting plate. The transition fillet 3 can reduce the damage of the corners of the framing tooling to the photovoltaic module. At the same time, since the corners of the photovoltaic module are all rounded, the transition fillet 3 can also make the inner side wall of the framing tooling fit more closely with the photovoltaic module. In some other embodiments, the clamping plate and the connecting plate can be multiple separate plates, and the multiple plates are connected and formed by welding.

[0038] In one embodiment, the clamping member 1 extends in an arc shape toward the end away from the connected ends of the clamping member 1, and the convex surfaces between a pair of clamping members 1 face each other. The convex part of the clamping member 1 is matched with the photovoltaic module, so as to reduce the contact area between the clamping member 1 and the photovoltaic module and prevent damage to the photovoltaic module when relative movement occurs between the clamping member 1 and the photovoltaic module.

[0039] In one embodiment, an elastic buffer 4 is connected to the opposite surfaces of the clamping member 1. The elastic buffer 4 is used to buffer the clamping force of the clamping member 1 on the photovoltaic module and avoid damage to the photovoltaic module caused by the clamping member 1.

[0040] Specifically, the elastic buffer 4 is a rubber buffer pad, a polyurethane buffer pad, a foam plastic buffer pad, an elastic sponge pad, an elastic fiber buffer pad, an elastic clay board or a spring piece. In this embodiment, the elastic buffer 4 is selected as a rubber buffer pad, and the rubber buffer pad completely covers the inner side surface of the clamping plate. In some other embodiments, as Figure 7 shown, the elastic buffer 4 may not be provided on the clamping member 1, and the clamping member 1 is directly in contact and cooperation with the photovoltaic module.

[0041] In one embodiment, a clamping member 5 is fixedly connected to the opposite surfaces of the clamping member 1, and the clamping member 5 and the clamping member 1 enclose a clamping hole 6. When installing the framing tooling on the photovoltaic module and when disassembling the framing tooling from the photovoltaic module body after the photovoltaic module is cured, an external device jaw can be inserted into the clamping hole 6, and a pair of clamping members 1 are opened by the external device jaw and then clamped on the photovoltaic module, which is convenient for realizing the automation of the photovoltaic module assembly process.

[0042] In one embodiment, the opposite surfaces of a pair of clamping members 5 away from the clamping member 1 are parallel to each other. After the framing tooling is installed on all four sides of the photovoltaic module, multiple photovoltaic modules with the framing tooling can be stacked, and the clamping members 5 are abutted back to back layer by layer, so that multiple layers of photovoltaic modules can be horizontally stacked and arranged, improving the stability of the stacked photovoltaic modules during transportation.

[0043] According to the embodiments of the present invention, on the other hand, a photovoltaic module is also provided, such asFigure 8 and 9 As shown, it includes the photovoltaic module framing tooling described in the present utility model, and also includes a battery panel lamination 8 and a module frame 7. When installing the tooling on the four sides of the full-screen module, the installation positions are as shown in Figure 8 shown. One clamping member 1 of the framing tooling is in contact with the front plate glass surface of the battery panel lamination 8, and the other clamping member 1 is in contact with the C surface of the module frame 7. The framing tooling tightly clamps the battery panel lamination 8 and the module frame 7 together and waits for curing. More than two framing toolings are installed on each long side of the full-screen module, and more than one framing tooling is installed on each short side. The photovoltaic module with the installed framing tooling flows into the curing workshop through the conveyor line and is cured in the stacked constant-temperature workshop. The stacking method is as shown in Figure 9 shown, and it is cured for more than four hours. After the adhesive has cured for four hours and the battery panel lamination 8 is firmly bonded to the module frame 7, the framing tooling is removed.

[0044] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the scope defined by the appended claims.
