[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] Since the glue points of the back contact (BC) battery cells are concentrated on the back of the battery, the existing BC components can be packaged using a conductive backplane. The conductive backplane is made of metal material. In order to avoid it directly contacting the back grid line of the BC battery cell to form a short circuit, an insulating layer needs to be set between the BC battery cell and the conductive backplane. The insulating layer needs to be opened (i.e., the point is removed) when in use, and the position of the opening is consistent with the position of the glue point on the back of the BC battery cell, so that the BC battery glue point can pass through the hole opened in the insulating layer and contact the metal on the conductive backplane to form current transmission.

[0035] The material of the above-mentioned insulating layer can be EVA, POE, EPE, PE, PF and other single-layer or multi-layer structures, and the holes can be made by mechanical stamping or laser through the perforated base plate. However, the position of the holes on the insulating layer is not only related to the design glue points of the battery cell itself, but also to the cell spacing and string spacing design of the module; and the existing perforated base plate can only be used to make holes in the insulating layer of photovoltaic modules with one cell and string spacing. Once the spacing changes, another perforated base plate needs to be replaced, otherwise the shape of the holes in the insulating layer will not be compatible with different module designs, which will cause risks such as short circuit, cold solder joints, and hidden cracks when the module is packaged.

[0036] In view of the above problems, an insulating layer de-pointing device is provided in an embodiment of the present application, such as Figures 1-2 As shown, it includes a base 10 and at least two supporting platforms 20; the supporting platforms 20 are arranged on the above-mentioned base 10, and each supporting platform 20 can be displaced and adjusted on the base 10 in at least one direction; the above-mentioned supporting platform 20 is used to carry the insulating layer, and a hole 21 is arranged on the top surface of the supporting platform 20 away from the base 10, and the above-mentioned hole 21 is used for the hole opening device to open the above-mentioned insulating layer. It should be noted that the insulating layer with the hole can be applied to the back contact photovoltaic module, but it is not limited to this, and it can also be used for other types of photovoltaic modules. The specific implementation of the insulating layer de-pointing device can be, for example: the insulating layer is placed above the insulating layer de-pointing device, the hole opening device is arranged above the insulating layer, and the hole opening device opens the above-mentioned insulating layer downward, and the hole opening position of the insulating layer corresponds to the hole position of the supporting platform, and the waste generated after the hole opening can fall to the bottom through the hole 21 of the insulating layer de-pointing device. The above is only an example, but it is not limited to this.

[0037] Among them, because the support platform 20 is used to support the insulating layer of the photovoltaic module, and the support platform 20 is provided with a hole 21 on the top surface away from the base 10, the above-mentioned hole 21 is used for the hole opening device to open holes in the above-mentioned insulating layer, that is, each hole 21 is matched and distributed according to the position of the glue point on the back of a single battery cell in the photovoltaic module, so that for each glue point, there is at least one hole 21 on the top surface of the support platform 20 opposite to it; at the same time, because each support platform 20 is arranged on the base 10, and can be displaced and adjusted on the base 10 in at least one direction, when the battery cell spacing in the photovoltaic module changes, the spacing distance between each support platform 20 can be adjusted by displacing the support platform 20 along the base 10, so that each support platform 20 can be accurately opposite to the insulating layer area that it needs to carry, and accordingly, the hole 21 on the support platform 20 can be opposite to the required hole opening position on the insulating layer, and the required hole opening position on the insulating layer corresponds to the glue point position on the back of the BC battery. That is, the hole 21 can be continuously used to make holes, so that the position of the hole can be accurately matched with the position where the glue point is required to be set.

[0038] The hole-opening device may be a mechanical punching device or a laser device, that is, the corresponding hole-opening method may be mechanical punching or laser punching.

[0039] In the embodiment of the present application, each support platform 20 is arranged to be displaceably adjusted on the base 10 in at least one direction, and the position of each support platform 20 can be adjusted to be opposite to the insulating layer area at the corresponding battery cell position in the photovoltaic module, so that the insulating layer of photovoltaic modules with different battery cell spacings can be drilled, thereby effectively improving the problem that the existing perforated bottom plate has poor versatility and cannot be effectively used for drilling holes in the insulating layer of photovoltaic modules with various cell and string spacings; in addition, since different component designs can be matched without directly replacing the support platform 20, the production efficiency and version switching time are greatly improved, and the cost of repair when a single mechanism is damaged is also reduced.

[0040] Optionally, in one embodiment, each carrier 20 can be displaced and adjusted on the base 10 along a first direction and a second direction, and the first direction is different from the second direction. Because the first direction is different from the second direction, the position of the carrier 20 on the base 10 can be adjusted more accurately by matching the movement in the first direction and the second direction, so as to better adapt to different punching positions.

[0041] Optionally, in a specific implementation, the first direction is perpendicular to the second direction, so that each support platform 20 can be adjusted to a target position more quickly to match the position of a cell in a photovoltaic module.

[0042] In practical applications, one of the first direction and the second direction is the length direction of the battery string in the photovoltaic module, and the other of the first direction and the second direction is the width direction of the battery string in the photovoltaic module. That is, one of the spacings in the first direction and the second direction is the cell spacing, and the other is the string spacing.

[0043] Optionally, in one embodiment, the base 10 includes a bracket 11 and at least two adjustment blocks 12 disposed on the bracket 11, and each of the adjustment blocks 12 can be displaced and adjusted relative to the bracket 11 along the first direction; at least two of the bearing platforms 20 are disposed on each of the adjustment blocks 12, and each of the bearing platforms 20 can be displaced and adjusted relative to the adjustment block 12 along the second direction. Because the adjustment block 12 can be displaced and adjusted relative to the bracket 11 along the first direction, and the bearing platform 20 is disposed on the adjustment block 12, the bearing platform 20 can be displaced and adjusted relative to the bracket 11 along the first direction; at the same time, because each of the bearing platforms 20 can be displaced and adjusted relative to the adjustment block 12 along the second direction, the bearing platform 20 can be displaced and adjusted relative to the base 10 in the first direction and the second direction.

[0044] Optionally, in one embodiment, Figure 1 , 3 As shown in Figure 4, the bracket 11 is provided with a first slot 111 extending along the first direction, and the adjustment block 12 is fixed to the first slot 111 by a first locking mechanism 121. Therefore, when it is necessary to adjust the position of the support platform 20 along the first direction, the first locking mechanism 121 can be opened and the adjustment block 12 can be moved along the first slot 111 to the corresponding position and then the first locking mechanism 121 can be locked, so that the support platform 20 can be adjusted along the first direction.

[0045] Optionally, the first slot 111 may be a slide rail, so as to facilitate smoother movement of the adjustment block 12 after the first locking mechanism 121 is opened, thereby driving the bearing platform 20 to adjust its position along the first direction.

[0046] Optionally, in a specific embodiment, the first locking mechanism 121 includes a first bolt, and a first screw hole (not shown) adapted to the first locking mechanism 121 is provided on the adjusting block 12, and the width of the first slot 111 is the same as the diameter of the first screw hole, or the width of the first slot 111 is greater than the diameter of the first bolt and smaller than the nut diameter of the first bolt, so that the first slot 111 can clamp the first bolt, thereby fastening the adjusting block 12 to the bracket 11.

[0047] Optionally, in a specific embodiment, Figure 5As shown, a first scale line 112 is provided along the first slot 111 on the bracket 11 , so as to accurately and quickly know the distance between the supporting platforms 20 in the first direction.

[0048] Optionally, in a specific embodiment, two of the above-mentioned brackets 11 are arranged in parallel, and each adjustment block 12 is respectively mounted between the two brackets 11, which not only makes the overall structure more compact and stable, but also makes it easier to accurately adjust the position of each adjustment block 12.

[0049] Optionally, in a specific embodiment, each first slot 111 is relatively arranged at the side of the two brackets 11, and each adjustment block 12 has a first hollow area 122, and the first hollow area 122 is used for the first locking mechanism 121 to move. In this specific embodiment, by providing the first hollow area 122 on the adjustment block 12, an operating space for the first locking mechanism 121 is formed, which facilitates the loosening and tightening operation of the first locking mechanism 121.

[0050] Alternatively, if Figure 6 As shown, the adjusting block 12 is in an E-shaped structure with its opening facing downward, which not only makes the upper part of the adjusting block 12 a planar structure with sufficient receiving surface to set the bearing platform 20, but also makes the adjusting block 12 have sufficient supporting strength to bear the bearing platform 20; it also makes the bottom of the adjusting block 12 form the first hollow area 122, which has sufficient operating space for the first locking mechanism 121 to perform loosening and tightening operations.

[0051] Optionally, in one embodiment, Figure 1 , 3 As shown in FIGS. 4 and 6 , the adjustment block 12 is provided with a second card slot 123 extending along the second direction, and the support platform 20 is fixed to the second card slot 123 by a second locking mechanism 124. Therefore, when it is necessary to adjust the position of the support platform 20 along the second direction, the second locking mechanism 124 can be opened and the support platform 20 can be moved along the second card slot 123 to the corresponding position and then the second locking mechanism 124 can be locked, so that the support platform 20 can be adjusted along the second direction.

[0052] Optionally, the second locking slot 123 may be a slide rail, so as to facilitate smoother adjustment of the support platform 20 along the second direction after the second locking mechanism 124 is opened.

[0053] Optionally, in a specific embodiment, the second locking mechanism 124 includes a second bolt, and a second screw hole (not shown) adapted to the second bolt is provided on the support platform 20, and the width of the second slot 123 is the same as the diameter of the second screw hole, or the width of the second slot 123 is greater than the diameter of the second bolt and smaller than the nut diameter of the second bolt, so that the second slot 123 can clamp the second bolt, thereby fastening the adjustment block 12 to the bracket 11.

[0054] Optionally, in a specific embodiment, a second scale line 125 is provided along the second slot 123 of the adjustment block 12 to facilitate accurate and quick knowledge of the distance between the support platforms 20 in the second direction.

[0055] Optionally, in a specific embodiment, each of the above-mentioned carriers 20 has a second hollow area, and the above-mentioned second hollow area is used for the second locking mechanism 124 to move. In this specific embodiment, by providing the second hollow area 126 on the carrier 20, an operating space for the second locking mechanism 124 is formed, which facilitates the loosening and tightening operation of the second locking mechanism 124.

[0056] Optionally, in an embodiment of the present application, the second screw hole is located on the bottom surface of the support platform 20, and the second locking mechanism 124 fixes the support platform 20 on the adjustment block 12 through the second screw hole on the bottom surface of the support platform 20. The above-mentioned second hollow area 126 is specifically arranged between the top surface and the bottom surface of the support platform 20. The second locking mechanism 124 can be conveniently loosened or tightened through the second hollow area 126 without occupying the top surface space.

[0057] In the embodiment of the utility model, the top surface shape of the above-mentioned supporting platform 20 matches the shape of the insulating layer area required to be supported in the photovoltaic module, so as to better support the drilling of the insulating layer.

[0058] Optionally, in one embodiment, Figure 7 and 8 As shown, the top surface of the above-mentioned support platform 20 is a rectangular structure, which can adapt to the shape of the battery cell in the existing photovoltaic module, so as to better support the corresponding insulation layer area. Among them, the size of the rectangular structure is consistent with the battery cell in the photovoltaic module. Optionally, the length of the above-mentioned rectangular structure is 160-230mm and the width is 80-115mm.

[0059] In practical applications, the hole 21 is a through hole perpendicular to the top surface of the carrier 20. The shape of the hole 21 can be circular, elliptical, rounded or rectangular, etc. The size of the hole 21 should be larger than the size of the opening on the insulating layer. The waste generated after punching can fall off to the bottom through the hole 21 to avoid remaining on the insulating layer and causing material foreign matter. For example, the minimum width of the hole 21 can be 1mm; in addition, the distribution of the holes 21 on the top surface of the carrier 20 is determined by the glue points on the back of a single cell in the photovoltaic module, and the number of the holes 21 is also the same as the number of glue points on the back of a single cell in the photovoltaic module. For example, if the glue points on the back of a single cell are distributed in n×m rows and columns, that is, the holes 21 are also composed of n×m rows and columns, where n represents columns and m represents rows.

[0060] In the present application embodiment, Fig. 9 As shown, the top surfaces of at least two load platforms 20 arranged on the base 10 are in the same plane. In addition, the specific number and distribution of the load platforms 20 on the base 10 are consistent with the number and distribution of the battery cells in the photovoltaic module. For example, 1 to 8 load platforms 20 can be set in the length direction of the battery string in the back-contact photovoltaic module. It can be determined according to the number of battery cells in the battery string, and no specific limitation is made here; 2 to 6 load platforms 20 can be set in the width direction of the battery string in the back-contact photovoltaic module. It can be determined according to the battery segmentation mode, such as the number of half-slice segmentation mode is 2, and the number of three-slice segmentation mode is 3. For example, 6 load platforms 20 can be set in the width direction of the battery string in the photovoltaic module on the base 10, and 2 load platforms 20 can be set in the length direction of the battery string in the photovoltaic module. Figure 1 , 2 And as shown in 9.

[0061] Fig. 9 Where d0 is the distance between two adjacent carriers 20 in the second direction, and d0 can be freely adjusted within the adjustment range of 0 to 50 mm, which is determined according to the required spacing of the cells of the photovoltaic component in the second direction; d1, d2, d3, d4, and d5 are the distances between two adjacent carriers 20 in the first direction, and d1, d2, d3, d4, and d5 can be freely adjusted within the adjustment range of 0 to 50 mm, which is determined according to the required spacing of the cells of the photovoltaic component in the first direction; wherein the spacing of the cells in one direction of the first direction and the second direction is the cell spacing, and the spacing of the cells in the other direction of the first direction and the second direction is the string spacing, which refers to the distance between adjacent cells in a cell string in a photovoltaic component, and the string spacing refers to the distance between a string of cells (i.e., a cell string) connected in series and another adjacent string of cells in a photovoltaic component; for example, the spacing in the first direction may be the string spacing, and the first direction may be, for example, the horizontal direction.

[0062] It should be additionally explained that the distances d0 or d1, d2, d3, d4, d5 at different positions in the figure may not be equal.

[0063] In the embodiment of the present application, by loosening the first locking mechanism 121, the adjusting block 12 is controlled to move freely on the bracket 11, so that the above-mentioned distances d1, d2, d3, d4, and d5 can be adjusted; and by loosening the second locking mechanism 124, the supporting platform 20 is controlled to move freely on the adjusting block 12, so that the above-mentioned distance d0 can be adjusted, and then the above-mentioned first locking mechanism 121 and the second locking mechanism 124 are locked, and the entire device is placed on the required equipment to realize the punching processing of the above-mentioned insulating layer.

[0064] In the embodiment of the present application, the existing perforated bottom plate is split into at least two bearing platforms 20 whose relative distance can be freely adjusted. The above-mentioned d0 distance can be adjusted by freely moving each bearing platform 20 in the second direction to adapt to different spacings in the second direction; when d0 is adjusted, the bearing platform 20 and the adjustment block 12 are locked by a simple second bolt. At this time, the bearing platform 20 and the adjustment block 12 are taken as a whole, and can be moved in the first direction on the bracket 11, corresponding to the above-mentioned distances d1 to d5, to adapt to different sheet spacings; when d1 to d5 are adjusted, the first bolt is locked to freely adjust the distance between any bearing platforms 20. It should be noted that in other embodiments, the above-mentioned distances d1 to d5 can also be adjusted first, and then the above-mentioned distance d0 can be adjusted.

[0065] In summary, in the present embodiment, the insulating layer de-pointing device in the present application includes a base 10 and at least two supporting platforms 20, the supporting platforms 20 are arranged on the base 10, and each supporting platform 20 can be displaced and adjusted on the base 10 in at least one direction, and the supporting platform 20 is used to support the insulating layer, and a hole 21 is arranged on the top surface of the supporting platform 20 away from the base 10, and the hole 21 is used for a hole-opening device to open a hole in the insulating layer; wherein, by arranging each supporting platform 20 to be displaced and adjusted on the base 10 in at least one direction, the position of each supporting platform 20 can be adjusted to be opposite to the insulating layer area at the corresponding cell position in the photovoltaic module, and the insulating layer of the photovoltaic modules with different cell spacing can be opened, thereby effectively improving the problem that the existing opening bottom plate has poor versatility and cannot be effectively used for opening holes in the insulating layer of photovoltaic modules with various cell and string spacings.
