[0026] Reference Figure 1As shown, this application provides a photovoltaic laminate edge sealing device for sealing the edges of photovoltaic laminates 200 with different widths for a front panel 210 and a back panel 220. The device includes a first connector 20, a first movable member 30, a second connector 40, and a second movable member 50. The first movable member 30 is movably disposed on the first connector 20. The second movable member 50 is movably disposed on the second connector 40. The first movable member 30 has a first contact surface 31 for contacting the portion of the edge sealing adhesive 300 located on the shorter panel. The second movable member 50 has a second contact surface 51 for contacting the portion of the edge sealing adhesive 300 located between the front panel 210 and the back panel 220, and a third contact surface 52 for contacting the portion of the edge sealing adhesive 300 located on the longer panel.
[0027] The aforementioned photovoltaic laminate edge sealing device can be used to seal the edges of photovoltaic laminates with misaligned front and back panels. The photovoltaic laminate edge sealing device of this application is used to seal the edges of photovoltaic laminates 200 with different widths for the front panel 210 and the back panel 220. In use, by moving the first moving member 30, the edge sealing adhesive 300 comes into contact with the first contact surface 31, and is compacted, so that the edge sealing adhesive 300 adheres to the surface of the shorter panel away from the longer panel. Then, by moving the second moving member 50, the edge sealing adhesive 300 is adhered to the end face of the shorter panel through the second contact surface 51, and is compacted through the third contact surface 52, so that the edge sealing adhesive 300 adheres to the longer panel and protrudes from the surface of the shorter panel. This allows the edge sealing adhesive 300 to adhere to the gap between the front panel 210 and the back panel 220, completing the edge sealing of the photovoltaic laminate with the misaligned design of the front panel 210 and the back panel 220, thus preventing adhesive overflow during the lamination process.
[0028] Understandably, in photovoltaic laminates with staggered front and back glass designs, the front glass is typically smaller in width than the back glass. Therefore, the end face of the front photovoltaic glass is positioned within the surface of the back photovoltaic glass. Sealing the edges of these staggered front and back glass laminates involves using edge-sealing adhesive to seal the gap between the front and back photovoltaic glass, preventing adhesive overflow during the lamination process.
[0029] In some embodiments, the rear panel 220 is a panel with a longer width.
[0030] In some embodiments, the front panel 210 is a panel with a shorter width.
[0031] In some embodiments, the photovoltaic laminate edge sealing device further includes a first driving member 10, which is electrically connected to a first moving member 30 and a second moving member 50. The first driving member 10 is used to drive the first moving member 30 and the second moving member 50 to move.
[0032] In some embodiments, the first connector 20 extends along the width direction of the photovoltaic laminate 200. The first movable member 30 is movable on the first connector 20 along both the width direction and the thickness direction of the photovoltaic laminate 200.
[0033] In actual use, the first moving part 30 can be driven along the width direction of the photovoltaic laminate 200 to move to a position close to the surface of the front panel 210 away from the back panel 220. Then, the first moving part 30 can be moved towards the front panel 210 along the thickness direction of the photovoltaic laminate 200 so that the edge sealing adhesive 300 is attached to the surface of the front panel 210 away from the back panel 220.
[0034] For example, the first moving member 30 may be disposed on the fifth moving member. The fifth moving member has a slide rail extending along the thickness direction of the photovoltaic laminate 200. The first connecting member 20 has a slide rail extending along the width direction of the photovoltaic laminate 200, and the fifth moving member is disposed on the slide rail of the first connecting member 20. The first driving member 10 is electrically connected to the fifth moving member, and the first driving member 10 is used to drive the fifth moving member to move along the width direction of the photovoltaic laminate 200 on the slide rail of the first connecting member 20. The first driving member 10 is also used to drive the first moving member 30 to move along the thickness direction of the photovoltaic laminate 200 on the slide rail of the fifth moving member.
[0035] Refer again Figure 1 As shown, exemplarily, Figure 1 The X direction is the width direction of the photovoltaic laminate 200, and the Y direction is the thickness direction of the photovoltaic laminate 200.
[0036] In some embodiments, the second connector 40 extends along the width direction of the photovoltaic laminate 200. The second connector 40 is offset from the first connector 20 in the thickness direction of the photovoltaic laminate 200. The second movable member 50 is movable on the second connector 40 along both the width direction and the thickness direction of the photovoltaic laminate 200.
[0037] The second connector 40 is offset from the first connector 20 in the thickness direction of the photovoltaic laminate 200. This allows the second connector 40 to be moved directly toward the end face of the front panel 210 along the width direction of the photovoltaic laminate 200 after one side of the edge sealant 300 is attached to the surface of the front panel 210 away from the back panel 220. This allows the edge sealant 300 to be attached to the end face of the front panel 210. Then, by moving the second connector 40 toward the back panel 220 along the thickness direction of the photovoltaic laminate 200, the edge sealant 300 can be attached to the surface of the back panel 220 that is exposed on the front panel 210.
[0038] For example, the second moving member 50 may be disposed on the sixth moving member. The sixth moving member has a slide rail extending along the thickness direction of the photovoltaic laminate 200. The second connecting member 40 has a slide rail extending along the width direction of the photovoltaic laminate 200, and the sixth moving member is disposed on the slide rail of the second connecting member 40. The first driving member 10 is electrically connected to the sixth moving member, and the first driving member 10 is used to drive the sixth moving member to move along the width direction of the photovoltaic laminate 200 on the slide rail of the second connecting member 40. The first driving member 10 is also used to drive the second moving member 50 to move along the thickness direction of the photovoltaic laminate 200 on the slide rail of the sixth moving member.
[0039] Reference Figure 2 As shown, in some embodiments, the photovoltaic laminate edge sealing device further includes a third connector 70 and a third movable member 80. The third movable member 80 is movably disposed on the third connector 70. The third movable member 80 has a fourth contact surface 81 for contacting the portion of the edge sealing adhesive 300 located on the end face of the wider panel.
[0040] The edge sealing adhesive 300 can be folded by the third moving part 80 and compacted by the fourth contact surface 81, so that the edge sealing adhesive 300 adheres to the end face of the panel with a longer width, thereby further improving the edge sealing effect of the edge sealing adhesive 300.
[0041] In some embodiments, the photovoltaic laminate edge sealing device further includes a second drive member 60. The second drive member 60 is electrically connected to a third moving member 80, and the second drive member 60 is used to drive the third moving member 80 to move.
[0042] In some embodiments, the third connector 70 includes a first sub-part extending along the width direction of the photovoltaic laminate 200. The third movable member 80 is movable on the first sub-part along the width direction of the photovoltaic laminate 200.
[0043] In some embodiments, the third connector 70 further includes a second sub-part extending along the thickness direction of the photovoltaic laminate 200. One end of the second sub-part is connected to the first sub-part, and the other end is connected to the second drive member 60. The third moving member 80 is movable on the second sub-part along the thickness direction of the photovoltaic laminate 200.
[0044] In some embodiments, the third connector 70 further includes a connecting portion. One end of the connecting portion is connected to the first sub-part, and the other end is connected to the second sub-part. The connecting portion is used to change the direction of movement of the third moving member 80 on the third connector 70.
[0045] For example, the first sub-part, the connecting part, and the second sub-part are all provided with connected slide rails. When the third moving member 80 moves on the third connecting member 70, it can first move along the thickness direction of the photovoltaic laminate 200 on the slide rail of the second sub-part, then change its movement direction through the slide rail of the connecting part, and then move along the width direction of the photovoltaic laminate 200 on the slide rail of the first sub-part, thereby realizing the folding of the edge sealing adhesive 300 and the adhesion of the edge sealing adhesive 300 to the end face of the back panel 220 through the fourth contact surface 81.
[0046] In some embodiments, the photovoltaic laminate edge sealing device further includes a fourth connector 90 and a fourth movable member 100. The fourth movable member 100 is movably disposed on the fourth connector 90. The fourth movable member 100 has a fifth contact surface 101 for contacting the portion of the edge sealing adhesive 300 located on the surface of the longer panel away from the shorter panel. A second drive member 60 is electrically connected to the fourth movable member 100. The second drive member 60 is used to drive the fourth movable member 100 to move.
[0047] In some embodiments, the fourth connector 90 extends along the width direction of the photovoltaic laminate 200. The fourth movable member 100 is movable on the fourth connector 90 along both the width direction and the thickness direction of the photovoltaic laminate 200.
[0048] Exemplarily, the fourth moving member 90 may be disposed on the seventh moving member. The seventh moving member has a slide rail extending along the thickness direction of the photovoltaic laminate 200. The fourth connecting member 90 has a slide rail extending along the width direction of the photovoltaic laminate 200, and the seventh moving member is disposed on the slide rail of the fourth connecting member 90. The second driving member 60 is electrically connected to the seventh moving member, and the second driving member 60 is used to drive the seventh moving member to move along the width direction of the photovoltaic laminate 200 on the slide rail of the fourth connecting member 90. The second driving member 60 is also used to drive the fourth moving member 100 to move along the thickness direction of the photovoltaic laminate 200 on the slide rail of the seventh moving member.
[0049] Refer again Figure 2As shown, the photovoltaic laminate edge sealing device, which includes a first moving part 30, a second moving part 50, a third moving part 80 and a fourth moving part 100, can apply the edge sealing adhesive 300 starting from the surface of the longer panel away from the shorter panel. First, the edge sealing adhesive 300 is adhered to one side of the back panel 220 away from the front panel 210 via the fifth contact surface 101 of the fourth moving member 100. Then, the edge sealing adhesive 300 is folded over via the fourth contact surface 81 of the third moving member 80 to adhere to the side of the back panel 220. Next, the edge sealing adhesive 300 is adhered to the surface of the back panel 220 exposed on the front panel 210 via the third contact surface 52 of the second moving member 50. The edge sealing adhesive 300 is adhered to the side of the front panel 210 via the second contact surface 51. Finally, the edge sealing adhesive 300 is adhered to the surface of the front panel 210 away from the back panel 220 via the first contact surface 31 of the first moving member 30, thus completing the edge sealing.
[0050] In some embodiments, the fifth contact surface 101 and the first contact surface 31 are arranged in parallel.
[0051] In some embodiments, the first contact surface 31 and the third contact surface 52 are arranged in parallel.
[0052] In some embodiments, the second contact surface 51 and the third contact surface 52 are arranged perpendicularly.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
