Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a correction device and lamination equipment. Background Technology

[0002] In the lamination process of photovoltaic (PV) modules, a lamination frame is placed around the outer perimeter of the PV module to reduce the pressure on the edges of the PV module during lamination. As the PV module moves between different workstations, the lamination frame needs to be aligned before and after entering the laminator to prevent it from shifting and pressing onto the PV module. The lamination frame is a rectangular frame structure, and a alignment device is typically used to compress the long and short sides of the lamination frame to achieve alignment.

[0003] However, the frame structure of the laminate is prone to deformation when subjected to the extrusion pressure of the straightening device, which can cause the laminate to jump out of the frame. This means that the laminate moves upward and presses on the photovoltaic module, causing the photovoltaic module to burst during the lamination process, which in turn leads to a degradation of the photovoltaic module's quality or even scrapping it. Utility Model Content

[0004] Therefore, it is necessary to provide a straightening device and lamination equipment to prevent the lamination frame from jumping out during the straightening process.

[0005] In a first aspect, this application provides a correction device, comprising:

[0006] A conveying mechanism for conveying laminated frames;

[0007] A straightening mechanism is provided on the conveying mechanism. The straightening mechanism is used to straighten the laminating frame. The straightening mechanism includes a first straightening wheel for abutting and cooperating with the laminating frame. The outer peripheral surface of the first straightening wheel is provided with a slot for inserting the laminating frame.

[0008] The technical solution will be further explained below:

[0009] In one embodiment, the correction mechanism includes:

[0010] A first alignment component is disposed on the conveying mechanism and is used to extrude both sides of the laminate frame in a first direction.

[0011] The second alignment component is disposed on the conveying mechanism and is used to extrude both sides of the laminate frame in a second direction;

[0012] Wherein, the first direction is the conveying direction of the conveying mechanism, the second direction is perpendicular to the first direction, and at least one of the first correction component and the second correction component is provided with the first correction wheel.

[0013] In one embodiment, the first correction component includes:

[0014] Two first limiting structures are arranged at intervals along the first direction, and at least one of the two first limiting structures is provided with a first aligning wheel;

[0015] A first driving structure is connected to two first limiting structures, and the first driving structure is used to drive the two first limiting structures to move closer to each other or further away from each other.

[0016] In one embodiment, the first limiting structure includes a first mounting bracket connected to the first driving structure. The first mounting bracket of one of the two first limiting structures is rotatably provided with a first centering wheel, and the first mounting bracket of the other is rotatably provided with a second centering wheel, the second centering wheel being a cylindrical structure.

[0017] In one embodiment, the number of first alignment wheels is multiple, and the multiple first alignment wheels are arranged at intervals along the second direction on the corresponding first mounting brackets; and / or, the number of second alignment wheels is multiple, and the multiple second alignment wheels are arranged at intervals along the second direction on the corresponding first mounting brackets.

[0018] In one embodiment, the second correction component includes:

[0019] Two second limiting structures are arranged at intervals along the second direction;

[0020] The second driving structure is connected to the two second limiting structures, and the second driving structure is used to drive the two second limiting structures to move closer to each other or further away from each other.

[0021] In one embodiment, the second limiting structure includes a second mounting frame and a plurality of third alignment wheels, the plurality of third alignment wheels being arranged at intervals along the first direction on the second mounting frame, and the third alignment wheels having a cylindrical structure.

[0022] In one embodiment, the slot extends circumferentially around the first alignment wheel and surrounds the first alignment wheel; and / or, the width of the slot gradually decreases along the opening of the slot towards the bottom of the slot.

[0023] In one embodiment, the conveying mechanism includes multiple conveying lines, each conveying line being used to convey the laminated frame along a first direction, and all the conveying lines being arranged at intervals along a second direction, wherein the first direction is perpendicular to the second direction.

[0024] Secondly, this application also provides a lamination apparatus, including the aforementioned correction device.

[0025] In the aforementioned straightening device, a slot is provided on the first straightening wheel of the straightening mechanism. When the straightening mechanism straightens the laminate frame, the first straightening wheel abuts against the edge of the laminate frame to straighten it. During this process, the edge of the laminate frame can be inserted into the slot. When the laminate frame is squeezed by the straightening mechanism, the slot can effectively restrict the upward displacement of the laminate frame, thereby preventing the laminate frame from jumping out of place and thus avoiding the cracking problem caused by the photovoltaic module being pressed down by the laminate frame.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0041] One embodiment of this application provides a straightening device for straightening laminate frames. Specifically, see [link to relevant documentation]. Figure 1 as well as Figure 2 One embodiment of the alignment device includes a conveying mechanism 10 and an alignment mechanism 20. The conveying mechanism 10 is used to convey the laminated frame; specifically, in actual operation, the conveying mechanism 10 can convey the laminated frame and the photovoltaic modules inside the laminated frame together. The alignment mechanism 20 is disposed on the conveying mechanism 10 and is used to align the laminated frame. Figure 3 The straightening mechanism 20 includes a first straightening wheel 2121 for abutting and engaging with the laminating frame. The outer peripheral surface of the first straightening wheel 2121 is provided with a slot 2124 for inserting the laminating frame.

[0042] In the aforementioned straightening device, a slot 2124 is provided on the first straightening wheel 2121 of the straightening mechanism 20. When the straightening mechanism 20 straightens the laminate frame, the first straightening wheel 2121 abuts against the edge of the laminate frame to straighten it. During this process, the edge of the laminate frame can be inserted into the slot 2124. When the laminate frame is squeezed by the straightening mechanism 20, the slot 2124 can effectively restrict the upward displacement of the laminate frame, thereby preventing the laminate frame from jumping out of the frame and thus avoiding the cracking problem caused by the photovoltaic module being pressed by the laminate frame.

[0043] See also Figure 1 as well as Figure 2 In one embodiment, the straightening mechanism 20 includes a first straightening component 21 and a second straightening component 22. The first straightening component 21 is disposed on the conveying mechanism 10 and is used to squeeze both sides of the laminate frame in a first direction. Exemplarily, the first straightening component 21 is used to straighten the two long sides of the laminate frame. The second straightening component 22 is disposed on the conveying mechanism 10 and is used to squeeze both sides of the laminate frame in a second direction. Exemplarily, the second straightening component 22 is used to straighten the two short sides of the laminate frame. The first direction is the conveying direction of the conveying mechanism 10, and the second direction is perpendicular to the first direction. Figure 2 In the diagram, the first direction is represented by the X-axis, and the second direction is represented by the Y-axis. By using the first alignment component 21 and the second alignment component 22 to compress the long and short sides of the laminate frame respectively, the laminate frame can be aligned to a preset position, preventing the pressure-bearing layer from shifting and pressing onto the photovoltaic module.

[0044] Furthermore, at least one of the first alignment component 21 and the second alignment component 22 is provided with a first alignment wheel 2121. For example, in this embodiment, the first alignment wheel 2121 is disposed on the first alignment component 21, and the slot 2124 is used to engage the long side of the lamination frame, thereby restricting the upward displacement of the lamination frame. Understandably, in other embodiments, the first alignment wheel 2121 may also be disposed on the second alignment component 22, or both the first alignment component 21 and the second alignment component 22 may be provided with the first alignment wheel 2121, which can also achieve the effect of restricting the upward displacement of the lamination frame.

[0045] See Figure 1 For example, in one embodiment, the first alignment component 21 includes a first driving structure 211 and two first limiting structures 212, which are arranged at intervals along a first direction. At least one of the two first limiting structures 212 is provided with a first alignment wheel 2121. The first driving structure 211 is connected to the two first limiting structures 212 and is used to drive the two first limiting structures 212 to move closer to or further away from each other.

[0046] Specifically, when the laminate frame enters the preset position under the conveying mechanism 10, the first driving structure 211 drives the two first limiting structures 212 to move closer to each other, so that the two first limiting structures 212 press against the two long sides of the laminate frame respectively, thereby correcting the long sides of the laminate frame. Since at least one of the two first limiting structures 212 is provided with a first correcting wheel 2121, when the first limiting structure 212 presses against the long side of the laminate frame, at least one long side of the laminate frame can be locked into the slot 2124 of the first correcting wheel 2121, thereby restricting the upward displacement of the laminate frame.

[0047] It is worth noting that the first drive structure 211 can be a linear module, an electric push rod, a gear and rack structure, or a lead screw and nut structure, as long as it can drive the two first limit structures 212 to move closer to or further away from each other along the first direction. No restrictions are imposed here.

[0048] See also Figure 1 In one embodiment, the first limiting structure 212 includes a first mounting bracket 2122 connected to the first driving structure 211. One of the two first limiting structures 212 has a first aligning wheel 2121 rotatably mounted on its first mounting bracket 2122, while the other has a second aligning wheel 2123 rotatably mounted on its first mounting bracket 2122. The second aligning wheel 2123 is cylindrical. The cylindrical second aligning wheel 2123 provides better positioning for the anti-pressure frame. Thus, one long side of the laminate frame is positioned and uppered by the first aligning wheel 2121 with a slot 2124, while the other long side is positioned by the cylindrical second aligning wheel 2123. This improves the alignment effect of the laminate frame while preventing upward displacement.

[0049] Furthermore, the number of first aligning wheels 2121 is multiple, such as two, three, four, or more, and these multiple first aligning wheels 2121 are arranged at intervals along the second direction on the corresponding first mounting brackets 2122. Similarly, the number of second aligning wheels 2123 is multiple, such as two, three, four, or more, and these multiple second aligning wheels 2123 are arranged at intervals along the second direction on the corresponding first mounting brackets 2122. In this way, when the two first limiting structures 212 compress the laminate frame, the force on both sides of the laminate frame is more even, preventing deformation of the laminate frame.

[0050] See Figure 1 In one embodiment, the second correction component 22 includes a second driving structure 221 and two second limiting structures 222, which are arranged at intervals along a second direction. The second driving structure 221 is connected to the two second limiting structures 222 and is used to drive the two second limiting structures 222 to move closer to or further away from each other.

[0051] Specifically, when the laminate frame enters the preset position under the conveying mechanism 10, the second driving structure 221 drives the two second limiting structures 222 to move closer to each other, so that the two second limiting structures 222 press against the two short sides of the laminate frame respectively, thereby correcting the short sides of the laminate frame.

[0052] It is worth noting that the second drive structure 221 can be a linear module, an electric push rod, a gear and rack structure, or a lead screw and nut structure, as long as it can drive the two second limit structures 222 to move closer to or further away from each other along the second direction. No restrictions are imposed here.

[0053] See Figure 1 In one embodiment, the second limiting structure 222 includes a second mounting bracket 2222 and a plurality of third straightening wheels 2221. The plurality of third straightening wheels 2221 are arranged at intervals along a first direction on the second mounting bracket 2222, and the third straightening wheels 2221 are cylindrical structures. The cylindrical third straightening wheels 2221 have a good positioning effect on the anti-pressure frame. Thus, both short sides of the laminate frame are positioned by the cylindrical third straightening wheels 2221, improving the straightening effect of the laminate frame. The number of third straightening wheels 2221 can be two, three, four or more, etc., and is not limited here. In this way, when the two second limiting structures 222 compress the laminate frame, the force on both sides of the laminate frame is more uniform, preventing the laminate frame from deforming.

[0054] See Figure 4 The slot 2124 extends circumferentially along the first aligning wheel 2121 and surrounds the first aligning wheel 2121, that is, the slot 2124 is an annular groove. In this way, no matter what angle the first aligning wheel 2121 rotates to, the laminate frame can be locked into the slot 2124 to limit the upward displacement of the laminate frame.

[0055] See also Figure 4 In one embodiment, the width L of the slot 2124 gradually decreases from the opening to the bottom. That is, the opening of the slot 2124 is wider, making it easier for the laminate frame to be inserted into the slot 2124; the bottom of the slot 2124 is narrower, which facilitates precise positioning of the laminate frame.

[0056] See Figure 2In one embodiment, the conveying mechanism 10 includes multiple conveying lines 11, each conveying line 11 for conveying the laminated frame along a first direction. The multiple conveying lines 11 are arranged at intervals along a second direction, wherein the first direction is perpendicular to the second direction. Exemplarily, the conveying mechanism 10 includes four conveying lines 11, which are arranged at intervals along the second direction. The four conveying lines 11 jointly convey the laminated frame, thereby ensuring that the laminated frame remains stable during conveying. Understandably, in other embodiments, the number of conveying lines 11 may also be two, three, five, six, or more, etc., and is not limited thereto.

[0057] Furthermore, in one embodiment, the first drive structure 211 of the first alignment component 21 is disposed below the conveyor line 11, and the first alignment wheel 2121 and the second alignment wheel 2123 protrude between the two conveyor lines 11, thereby preventing the two first limiting structures 212 from colliding with the conveyor line 11 when they approach or move away from each other. The second drive structure 221 of the second alignment component 22 is also disposed below the conveyor line 11, and the two second limiting structures 222 are respectively arranged on both sides of the conveying mechanism 10 in the second direction, thereby preventing the two second limiting structures 222 from colliding with the conveyor line 11 when they approach or move away from each other.

[0058] This application also includes, in another aspect, a lamination apparatus, one embodiment of which includes the correction device of any of the above embodiments. The lamination apparatus is used to laminate photovoltaic modules to expel air from the photovoltaic modules and to connect the structural layers of the photovoltaic modules together.

[0059] 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.

[0060] 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 application. 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
