Description

Technical Field

[0001] The invention relates to a stamping system and a stamping process for producing a self-cleaning frame structure for a photovoltaic module. Background Art

[0002] At present, in order to prevent the frame structure used to support the photovoltaic module from intercepting rainwater and the dust accumulated on the surface of the photovoltaic module by rainwater washing, a diversion area is designed in the mounting groove of the frame structure (the mounting groove accommodates the edge of the photovoltaic module) so that water and dust can flow out through the diversion area. The diversion area generally includes a diversion groove surrounded by the top plate of the mounting groove and the upper surface of the photovoltaic module, and a drainage port arranged on the side plate of the mounting groove and connected to the diversion groove. On the basis of the frame structure that fully wraps the edge of the photovoltaic module that has been prepared, the stamping core block is directly used for one-step stamping to simultaneously remove the portion of the top plate of the mounting groove that presses against the edge of the photovoltaic module and part of the side plate of the mounting groove.

[0003] On the one hand, the existing one-step stamping method of the stamped core block can easily cause the top plate retained in the installation groove to deform, causing irreversible damage to the non-processed position; on the other hand, the one-step stamping method can also easily cause the stamped core block to be stuck in the installation groove, and the non-processed position can also be irreversibly damaged during the disassembly of the stamped core block. Summary of the invention

[0004] In view of this, the present invention provides a stamping system and stamping process for producing a self-cleaning frame structure for photovoltaic modules, which can avoid stamping damage to the frame structure through the cooperation between the top support plate and the top plate stamping core block and the side support plate and the side plate stamping core block, thereby improving the yield rate of the self-cleaning frame structure.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] In a first aspect, the present invention provides a punching system for producing a self-cleaning frame structure for a photovoltaic module, comprising: a top plate punching device and a side plate punching device, wherein:

[0007] The top plate punching device comprises: a top supporting plate and a top plate punching core block;

[0008] The side plate punching device comprises: a side support plate and a side plate punching core block;

[0009] A first notch area is provided at one end of the top supporting plate, and except for the first notch area, the shape of the upper surface of the top supporting plate matches the shape of the outer surface of the top plate of the frame structure, wherein the frame structure includes a mounting groove that fully wraps the edge of the photovoltaic module;

[0010] After receiving the driving force, the top plate stamping core block uses the mounting groove to stamp out the top plate portion of the frame structure corresponding to the first notch area;

[0011] The side support plate is provided with a second notch area;

[0012] The side supporting plate supports the side plate of the frame structure through the area outside the second notch area;

[0013] The side panel punching core block punches the side panel portion corresponding to the second notch area in the frame structure after receiving the driving force.

[0014] In a second aspect, an embodiment of the present invention provides a stamping process implemented by a stamping system based on the embodiment of the first aspect, including:

[0015] Step 1: placing a top plate of a frame structure including a mounting groove that fully wraps the edge of a photovoltaic module on a top supporting plate, and stabilizing the frame structure;

[0016] Step 2, driving the top plate stamping core block so that the top plate stamping core block uses the mounting groove to stamp the top plate portion corresponding to the first notch area of ​​the top supporting plate;

[0017] Step 3: placing the frame structure punched in step 2 on the side support plate, and stabilizing the frame structure;

[0018] Step 4: drive the side panel punching core block to punch the side panel portion in the frame structure corresponding to the second notch area of ​​the side support plate.

[0019] The technical solution of the first aspect of the above invention has the following advantages or beneficial effects:

[0020] The technical solution provided by the embodiment of the present invention cooperates the top support plate and the top plate stamping core block in the stamping system, and matches the shape of the upper surface of the top support plate with the shape of the outer surface of the top plate of the frame structure, so that the top support plate can provide relatively good support for the top plate. In the process of using the top plate stamping core block to impact the part of the top plate corresponding to the first notch area, the part of the top plate that needs to be retained can still be relatively well supported because it matches the shape of the top support plate, thereby avoiding the part of the top plate that needs to be retained from being affected and deformed. After removing the portion of the top plate corresponding to the first notch area, the side support plate is used to cooperate with the side plate stamping core block. Since the portion of the top plate corresponding to the first notch area extends toward the side plate through the portion of the side plate corresponding to the second notch area, after the portion of the top plate corresponding to the first notch area has been removed, the side plate stamping core block is used for impact, so that the side plate stamping core will no longer be clamped by the top plate, and during the impact of the side plate stamping core block, the side support plate supports the portion of the side plate that needs to be retained, thereby avoiding deformation of the retained portion of the side plate. Therefore, the stamping system provided in the embodiment of the present invention can avoid damage to the frame structure by stamping, and improve the yield rate of the self-cleaning frame structure.

DETAILED DESCRIPTION

[0041] Figure 1 FIG. 2 shows a frame structure 00 for which the punching system provided by the embodiment of the present invention is directed. Figure 1 As shown, the frame structure 00 includes a mounting groove that fully wraps the edge of the photovoltaic module, including: a top plate 01, a side plate 02 and a bottom plate 03. The top plate 01 of the frame structure 00 has a certain thickness, which will intercept rainwater and dust deposited by rainwater, causing the dust deposited by rainwater to accumulate in the corners of the photovoltaic module. In order to solve the problems such as the hot spot effect of the photovoltaic module caused by dust accumulation. At present, a method such as Figure 2The self-cleaning frame structure 00' shown in the figure removes part of the inner side surface of the top plate 01 and part of the side plate 02, so that the light-receiving surface of the photovoltaic module and part of the top plate 01 enclose a water flow path, and the water flow path is connected with the gap formed by the side plate 02, so that rainwater carrying accumulated dust is discharged from the water flow path and the gap on the side plate 02, and will not accumulate on the light-receiving surface of the photovoltaic module, so that the light-receiving surface of the photovoltaic module remains clean. However, if Figure 3 and Figure 4 As shown, the current process for preparing the self-cleaning frame structure 00' mainly uses the existing stamping core block 30 to simultaneously remove the inner side surface of the top plate 01 and the side plate 02 through a one-step stamping process. In the existing one-step stamping process, on the one hand, the stamping process will affect the non-processed area of ​​the top plate 01 and the non-processed area of ​​the side plate 02, causing the non-processed area of ​​the top plate 01 and the non-processed area of ​​the side plate 02 to deform; on the other hand, the existing stamping core block 30 is easily stuck in the installation groove, and the non-processed position will also be irreversibly damaged during the disassembly of the existing stamping core block 30.

[0042] In order to solve the above problems existing in the one-step stamping production of the self-cleaning frame structure 00' using the existing stamping core block 30, the embodiment of the present invention provides a new stamping system for producing the self-cleaning frame structure for photovoltaic modules and a stamping process based on the new stamping system.

[0044] The cross section involved in the embodiment of the present invention refers to the cut surface of each structural part obtained by cutting along a direction perpendicular to the extension direction of the frame structure.

[0045] The "first", "second", etc. involved in the embodiments of the present invention are for distinguishing different structures or components or different positions of the same structure, and are not intended to limit the number, order, etc. of structures or components. For example, the first notch area involved in the embodiments of the present invention refers to the notch located on the top plate 01, and the second notch area involved in the embodiments of the present invention refers to the notch located on the side plate 02. For another example, the first supporting portion 212 generally refers to the portion of the top plate 01 of the side support plate 21 that supports the frame structure when the frame structure is placed on the side support plate 21, and the second supporting portion 213 generally refers to the portion of the side plate 02 of the side support plate 21 that supports the frame structure when the frame structure is placed on the side support plate 21.

[0046] like Figures 5 to 15 As shown in (a) to (c) in the figure, the stamping system for producing the self-cleaning frame structure for photovoltaic modules provided by the embodiment of the present invention may include: a top plate stamping device 10 and a side plate stamping device 20.

[0047] Among them, Figure 5 and Figure 6 As shown, the top plate punching device 10 may include: a top supporting plate 11 and a top plate punching core block 12. Fig.12 and Fig.13 As shown, the side panel punching device 20 may include: a side support plate 21 and a side panel punching core block 22 .

[0048] For the above-mentioned top supporting plate 11, as Figure 8 As shown in (a) to (f) in FIG. 1 , a first notch region 111 is provided at one end of the top supporting plate 11, and in addition to the first notch region 111, as shown in FIG. Figure 5 and Figure 6As shown, the shape of the upper surface of the top support plate 11 matches the shape of the outer surface of the top plate of the frame structure 00, wherein the frame structure 00 includes a mounting groove that fully wraps the edge of the photovoltaic module; accordingly, after the top plate stamping core block 12 is subjected to the driving force, as shown in FIG. Figure 5 and Figure 6 As shown, by punching the top plate 01 portion of the frame structure 00 corresponding to the first notch area 111 with the installation groove, the following is obtained: Fig. 9 or Fig.10 By designing the shape of the upper surface of the top supporting plate 11 to match the shape of the outer surface of the top plate of the frame structure 00, the top supporting plate 11 can provide better support for the top plate of the frame structure 00. In addition, by cooperating with the top plate stamping core block 12 through the first notch area 111, the part of the top plate 01 to be removed can be positioned more accurately.

[0049] Among them, Figure 5 and Figure 6 As shown, the top plate 01 included in the frame structure 00 corresponds to the hook area of ​​the opening of the installation frame, which is generally a curved surface bending structure facing the inside of the installation frame. Accordingly, one side of the top supporting plate 11 is a curved surface matching the hook area of ​​the top plate 01, so as to better abut the hook area of ​​the top plate 01, so that the top plate stamping core block 12 can be downward from the inside of the installation frame (such as Figure 5 and Figure 6 The impact direction D) shown in the punching process of the top plate 01 can ensure that the shape of the remaining part of the hook area will not be destroyed.

[0050] Further, with respect to the side support plate 21 included in the side plate punching device 20, as Fig.15 As shown in (a) to (c) of FIG. 1 , the side support plate 21 is provided with a second notch area 211; the side support plate 21 supports the side plate 02 of the frame structure 00 through the area outside the second notch area 211. Fig.12 and Fig.13 As shown, after the side plate punching core block 22 is subjected to the driving force, the side plate 02 portion corresponding to the second notch area 211 in the frame structure 00 is punched to obtain the following Fig.16 or Fig.17 The structure shown in FIG. Fig.16 and Fig.17 As shown, the portion of the top plate 01 corresponding to the first notch area 111 extends toward the side plate 02 through the portion of the side plate 02 corresponding to the second notch area 211, so that the portion of the top plate 01 corresponding to the first notch area 111 forms a water flow path with the light-receiving surface of the photovoltaic module, and the water flow path is connected to the portion of the side plate 02 corresponding to the second notch area 211.

[0051] The surface of the side support plate 21 is a planar structure to better support the side plate 02 .

[0052] Among them, the cross section of the top plate stamping core block 12 matches the first notch area 111. Through this structural design, it can be ensured that the part of the top plate 01 that needs to be removed is completely removed under the cooperation of the top plate stamping core block 12 and the first notch area 111, and the top support plate 11 is prevented from affecting the top plate stamping core block 12. In addition, by designing the cross section of the top plate stamping core block 12 to match the first notch area 111, it is possible to avoid deformation or curling of the remaining part of the top plate 01 near the first notch area 111, and further ensure that the structure and shape of the remaining part of the top plate 01 will not be deformed.

[0053] In addition, the cross section of the side panel stamping core block 22 matches the second notch area 211, which can ensure that the part of the side panel 02 that needs to be removed is completely removed under the cooperation of the side panel stamping core block 22 and the second notch area 211, and avoid the side support plate 21 from affecting the side panel stamping core block 22. In addition, by setting this structural design, it is also possible to avoid deformation or curling of the remaining part of the side panel 02 near the second notch area 211, and further ensure that the structure and shape of the remaining part of the side panel 02 will not be deformed. Thereby ensuring the yield rate of the self-cleaning frame structure for the photovoltaic module.

[0054] In summary, in the stamping system provided by the embodiment of the present invention, the top support plate and the top plate stamping core block cooperate with each other, and the shape of the upper surface of the top support plate is matched with the shape of the outer surface of the top plate of the frame structure, so that the top support plate can provide better support for the top plate. In the process of using the top plate stamping core block to impact the part of the top plate corresponding to the first notch area, the part of the top plate that needs to be retained can still be better supported because it matches the shape of the top support plate, thereby avoiding the part of the top plate that needs to be retained from being deformed. After removing the portion of the top plate corresponding to the first notch area, the side support plate is used to cooperate with the side plate stamping core block. Since the portion of the top plate corresponding to the first notch area extends toward the side plate through the portion of the side plate corresponding to the second notch area, after the portion of the top plate corresponding to the first notch area has been removed, the side plate stamping core block is used for impact, so that the side plate stamping core will no longer be clamped by the top plate, and during the impact of the side plate stamping core block, the side support plate supports the portion of the side plate that needs to be retained, thereby avoiding deformation of the retained portion of the side plate. Therefore, the stamping system provided in the embodiment of the present invention can avoid damage to the frame structure by stamping, and improve the yield rate of the self-cleaning frame structure.

[0055] The implementation structure of the top supporting plate 11 is described in detail below.

[0056] Specifically, Figure 5 , Figure 6 , Figure 7 (a) to (g) and Figure 8As shown in (a) to (f), the top support plate 11 may include: a fixing portion 112 and various types of regulating portions 113, wherein one end of the fixing portion 112 is detachably connected to the regulating portion 113; the upper surface of the fixing portion 112 is a planar shape; the upper surface of the regulating portion 113 matches the shape of the outer surface of the hook area 011 of the top plate 01; after the regulating portion 113 is connected to the fixing portion 112, a first notch area 111 is enclosed; the various types of regulating portions 113 have different sizes, and they cooperate with the fixing portion 112 to regulate the position and size of the first notch area 111.

[0057] For example, Figure 7 (a) to (f) in FIG. 1 show various types of control units 113, wherein the different types of control units 113 can be used independently or in combination.

Through the above-mentioned various combinations, first notch areas 111 of different positions and sizes can be combined according to needs to better meet the needs of different structures.

[0058] Among them, a specific implementation form of the detachable connection between one end of the fixing part 112 and the regulating part 113 can be that a groove is provided on the side of one end of the fixing part 112; a protrusion is provided on the side of the regulating part 113; the fixing part 112 and the regulating part 113 are detachably connected through the groove and the protrusion. In addition, the one end of the fixing part 112 and the regulating part 113 can also be detachably connected by screws or the like.

[0059] It is worth noting that various models of regulating parts 113 generally refer to parameters such as size and surface curvature of the regulating parts 113 having certain differences, so that the part of the top plate 01 corresponding to the first notch area 111 that is impacted can meet different requirements.

[0060] Furthermore, if Figure 5 and Figure 6 As shown, the top plate stamping core block 12 may include a guide portion 121 and various types of stamping portions 122, wherein the various types of stamping portions 122 have different thicknesses to adapt to installation slots of different heights of the frame structure 00; the guide portion 121 and the stamping portion 122 are detachably connected; the guide portion 121, driven by a driving force, guides the stamping portion 122 to be embedded in the installation slot and stamps downwardly a portion of the top plate 01 corresponding to the first notch area 111. Different types of stamping portions 122 may be selected according to the width of the installation slot included in the frame structure 00, so that the stamping portion 122 can impact the top plate 01 while avoiding the stamping portion 122 from being stuck in the installation slot.

[0061] In addition, based on the deformation of the top plate stamping core block 12 and the top supporting plate 11, the embodiment of the present invention can also provide Fig.11 The top support plate 11 shown cooperates with the top plate stamping core block 12. Fig.11 As shown, one side of the upper surface of the top support plate 11 matches the hook area in the inner surface of the top plate 01, and a notch area is provided on the side of the top support plate 11 that matches the hook area. By punching the portion corresponding to the notch area through the top plate punching core block 12, a Fig. 9 or Fig.10 The structure shown.

[0063] For example, Fig.14 (a), (b) and (c) show various types of first supporting parts 212. Fig.14 The first supporting portion 212 shown in (a) and Fig.14 The second supporting portion 213 shown in (d) is combined to form Fig.15 The side support plate 21 shown in (a); Fig.14 The first supporting portion 212 shown in (b) and Fig.14The second supporting portion 213 shown in (d) is combined to form Fig.15 The side support plate 21 shown in (b); Fig.14 The first supporting portion 212 shown in (c) and Fig.14 The second supporting portion 213 shown in (d) is combined to form Fig.15 The side support plate 21 shown in (c) in FIG.

[0064] Different types of first supporting parts 212 and second supporting parts 213 cooperate to form side supporting plates 21 with different structures, so as to meet the requirements of opening notches of different sizes at different positions of the side plate 02 .

[0065] It is worth mentioning that Figure 7 (a) to (f) and Fig.14 (a) to (c) are only examples, and the regulating portion 113 and the first supporting portion 212 may also have other models or structures.

[0066] Furthermore, the stamping system may further include: a transport support structure (not shown in the figure), wherein the transport support structure is used to transport the frame structure 00 to the top support plate 11 and the side support plate 21 in sequence, and respectively cooperate with the top support plate 11 and the side support plate 21 to stabilize the frame structure 00. The transport support structure can enable the frame structure 00 to be transported from the top plate stamping device 10 to the side plate stamping device 20, so as to realize automatic stamping of the self-cleaning frame structure and reduce manual participation.

[0067] It is worth noting that the above-mentioned stamping system can be used as an independent system, and it can also be assembled into the existing frame structure production system as a part of the existing frame structure production system.
