[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] This utility model provides a photovoltaic module busbar fixing fixture and a photovoltaic module laminating device. Several embodiments are given below to describe in detail the photovoltaic module busbar fixing fixture and photovoltaic module laminating device provided by this utility model.
[0022] Example 1 The photovoltaic module busbar fixing fixture provided in this embodiment, such as Figures 3 to 4 As shown, it includes a fastener 1; the fastener 1 is used to attach to the glass plate of the photovoltaic module; the fastener 1 is provided with multiple through holes, and the multiple through holes are arranged one-to-one with the multiple busbars 3 of the photovoltaic module; the through holes are sleeved on the busbars 3 to restrict the position of the busbars 3.
[0023] Holes are made in the glass plate of the photovoltaic module, and multiple busbars 3 extend out of the glass plate through the holes. The multiple busbars 3 are spaced apart circumferentially along the holes. Before lamination, the fastener 1 is attached to the glass plate of the photovoltaic module. Multiple through holes are set one-to-one with multiple busbars 3. For example, when there are three busbars 3, there are three through holes, and each through hole corresponds to a different busbar 3.
[0024] Each through hole is fitted onto the busbar 3 corresponding to the through hole. The through hole can restrict the position of the busbar 3, thereby restricting multiple busbars 3 to a preset position by multiple through holes, preventing the busbar 3 from twisting and deforming after lamination, and causing a short circuit by overlapping with other busbars 3.
[0025] Among them, such as Figure 5 As shown, after each manifold 3 passes through the through hole, the manifold 3 bends towards the outside of the hole, so that the manifold 3 is almost parallel to the end face of the fastener away from the glass plate, and then lamination can be performed.
[0026] By using the photovoltaic module busbar fixing fixture provided in this embodiment, the position of the busbar 3 is restricted by the through holes. This prevents short circuits between the busbars 3 without increasing the spacing between them, thus avoiding an increase in the size of the junction box and the associated cost.
[0027] Furthermore, the plurality of through holes includes a first through hole 11, a second through hole 12 and a third through hole 13; along a first direction, the first through hole 11 and the second through hole 12 are disposed opposite to each other; along a second direction, at least one side of the first through hole 11 and the second through hole 12 is provided with the third through hole 13; the first direction is perpendicular to the second direction.
[0028] Both the first and second directions are parallel to the plane containing the glass panel of the photovoltaic module. The first direction is as follows: Figure 3 The direction indicated by the middle arrow ab, the second direction is as follows Figure 3 The direction indicated by the middle arrow cd.
[0029] Along the first direction, the first through hole 11 and the second through hole 12 are arranged at intervals relative to each other.
[0030] Along the second direction, a third through hole 13 can be provided on one side of the first through hole 11 and the second through hole 12, so that there are three through holes, which can be used for four-slice photovoltaic modules of three busbars 3. Alternatively, a third through hole 13 can be provided on both sides of the first through hole 11 and the second through hole 12, so that there are four through holes, which can be used for four-slice photovoltaic modules of four busbars 3.
[0031] In use, a manifold 3 is inserted into the first through hole 11, a manifold 3 is inserted into the second through hole 12, and a manifold 3 is inserted into the third through hole 13.
[0032] Furthermore, along the second direction, a third through hole 13 is provided on both sides of the first through hole 11 and the second through hole 12.
[0033] When there are four busbars 3 in a four-slice photovoltaic module, a third through hole 13 needs to be provided on both sides of the first through hole 11 and the second through hole 12, so that the number of through holes is four.
[0034] The two third through holes 13 are arranged at intervals relative to each other along the second direction. A busbar 3 is inserted into the first through hole 11, a busbar 3 is inserted into the second through hole 12, a busbar 3 is inserted into one third through hole 13, and a busbar 3 is inserted into the other third through hole 13.
[0035] Furthermore, the end face of the fastener 1 facing away from the photovoltaic module is the first end face; the first end face is provided with a conductive layer 2; along the first direction, the third through hole 13 is provided on the side of the first through hole 11 facing the second through hole 12, and the conductive layer 2 is provided on the side of the first through hole 11 facing the second through hole 12, so that the busbars 3 extending from the second through hole 12 and the third through hole 13 can both contact the conductive layer 2.
[0036] Specifically, along the first direction, a third through-hole 13 is disposed between the first through-hole 11 and the second through-hole 12, with the third through-hole 13 located on the side of the first through-hole 11 facing the second through-hole 12. A conductive layer 2 is disposed on the area of the first end face located on the side of the first through-hole 11 facing the second through-hole 12, allowing the busbar 3 extending from the second through-hole 12 to contact the conductive layer 2 after bending, and the busbar 3 extending from the third through-hole 13 to contact the conductive layer 2 after bending. This arrangement allows the busbars 3 extending from the second through-hole 12 and the third through-hole 13 to be electrically connected through the conductive layer 2, enabling the photovoltaic module to be tested using two probes of an EL tester. During testing, one probe contacts the first test point of the busbar 3 extending from the first through-hole 11, and the other probe contacts the second test point of the busbar 3 extending from the second through-hole 12. Additionally, the other probe can also contact the conductive layer 2.
[0037] It should be noted that when there is one or two third through holes 13, all the third through holes 13 are located along the first direction on the side of the first through hole 11 facing the second through hole 12, and the busbars 3 extending from all the third through holes 13 can contact the conductive layer 2.
[0038] The fastener 1 can be plate-shaped or block-shaped. It can be made of nylon, epoxy, polyimide, or bakelite. In this embodiment, the fastener 1 has a length of 30mm-200mm, a width of 10mm-100mm, and a thickness of 0.5mm-3mm.
[0039] The conductive layer 2 can be made of metal materials such as copper or aluminum, or alloy materials such as copper alloys or aluminum alloys.
[0040] An EL tester, short for Electroluminescent Tester, is a device for detecting internal defects in solar cells or battery modules.
[0041] Furthermore, the conductive layer 2 is bonded, sprayed, sputtered, or plated on the first end face.
[0042] The conductive layer 2 can be fixed to the first end face by processes such as chemical plating, electroplating, PVD sputtering, spraying or bonding.
[0043] Using the above method to set the conductive layer 2 on the first end face, the processing technology is relatively simple and the processing cost is low.
[0044] Furthermore, the fastener 1 includes a first plate and a second plate, which are arranged sequentially along a first direction, and the first plate and the second plate are fixedly connected; a first through hole 11 is provided in the first plate, and a second through hole 12 and a third through hole 13 are both provided in the second plate, so that the busbars 3 extending from the second through hole 12 and the third through hole 13 can contact the second plate; the second plate is conductive.
[0045] The first plate can be made of nylon, epoxy, polyimide, or bakelite, etc. The second plate can be made of metal such as copper or aluminum, or an alloy such as copper alloy or aluminum alloy.
[0046] Specifically, along the first direction, a third through-hole 13 is disposed between the first through-hole 11 and the second through-hole 12, with the third through-hole 13 located on the side of the first through-hole 11 facing the second through-hole 12. Both the second through-hole 12 and the third through-hole 13 are disposed on the second plate, allowing the busbar 3 extending from the second through-hole 12 to bend and contact the second plate, and vice versa. This arrangement enables the busbars 3 extending from the second through-hole 12 and the third through-hole 13 to be electrically connected through the second plate, allowing the photovoltaic module to be tested using two probes of an EL tester. During testing, one probe contacts the first test point of the busbar 3 extending from the first through-hole 11, and the other probe contacts the second test point of the busbar 3 extending from the second through-hole 12. Additionally, the other probe can also contact the second plate.
[0047] It should be noted that when there is one or two third through holes 13, all the third through holes 13 are located along the first direction on the side of the first through hole 11 facing the second through hole 12, and the manifold 3 extending from all the third through holes 13 can contact the second plate.
[0048] The first and second plates can be fixed by bonding or welding, or they can be made into a single piece.
[0049] Furthermore, the first plate and the second plate are integrally formed structures.
[0050] The first plate and the second plate are integrally formed, and the integrity of the first plate and the second plate is high, making it difficult for the first plate and the second plate to separate.
[0051] Furthermore, the through hole is a rectangular through hole. The shape of the through hole matches the manifold 3, which can effectively limit the movement of the manifold 3.
[0052] Furthermore, a polished layer is provided at the edge of the fastener 1 and the edge of the through hole.
[0053] A polishing layer is provided at the edge of the fastener 1 and the edge of the through hole to prevent the fastener 1 and the through hole from causing wear to the photovoltaic module.
[0054] The photovoltaic module busbar fixing fixture provided in this embodiment can ensure that there are no new defects such as hidden cracks or broken pieces during the lamination process. The photovoltaic module busbar fixing fixture does not deform after lamination and can be reused, saving tooling costs. The area of the photovoltaic module busbar fixing fixture can be set to a large value, such as 300 square millimeters to 20,000 square millimeters, and it is compatible with process equipment and can be placed and removed by suction cups and other methods.
[0055] Example 2 The photovoltaic module lamination device provided in this embodiment includes the photovoltaic module busbar fixing fixture provided in Embodiment 1.
[0056] Each through-hole is fitted onto the corresponding busbar 3. The through-hole restricts the position of the busbar 3, thereby confining multiple busbars 3 to preset positions by multiple through-holes. This prevents the busbars 3 from twisting and deforming after lamination, and from overlapping with other busbars 3, causing a short circuit. Using the photovoltaic module lamination device provided in this embodiment, the position of the busbars 3 is restricted by the through-holes, preventing short circuits between busbars 3 without increasing the spacing between them. This avoids increasing the size of the junction box and thus avoiding increased junction box costs.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
