[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model.

[0049] The structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this utility model can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0050] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] As mentioned in the background, in the existing photovoltaic module manufacturing process, due to the need for technical parameter adjustments or fault repair, it is necessary to rework the already welded cell strings. Photovoltaic modules typically consist of overlapping glass, a front encapsulant film, multiple cell strings, a rear encapsulant film, and a backsheet. Therefore, during the rework process, the glass and front encapsulant film overlapping the cell strings must first be removed and transported before the cell strings can be repaired. This process requires multiple handling operations, which can easily lead to damage to the modules during transport, affecting product quality and production efficiency. To better solve this problem, the researchers in this application propose a support device for photovoltaic module pre-lamination rework, which can support the glass, cell strings, and encapsulant film during rework, thereby solving the problem of damage to the modules during transport.

[0052] like Figure 1 and Figure 4 As shown, Figure 1This is a schematic diagram of the structure of the support device for pre-lamination repair of photovoltaic modules in one embodiment of this application. Figure 4 This is a schematic diagram of the structure of a support device for pre-lamination repair of photovoltaic modules according to another embodiment of this application. The support device for pre-lamination repair of photovoltaic modules includes a support body 100, on which a first support position 200, a third support position 400, and a repair component are provided. The first support position 200 is located at the top of the support body 100, the third support position 400 is located at the bottom of the support body 100, and the repair component is located between the first support position 200 and the third support position 400. The repair component is slidably disposed on the support body 100 and has a clamping member 160 for clamping the adhesive film 530 and a second support position 300 for carrying the battery string 520.

[0053] According to the bearing device of the above embodiment, during repair, the photovoltaic module is first placed on the third bearing position 400; then the top layer of glass of the photovoltaic module is peeled off and placed on the first bearing position 200, exposing the adhesive film 530 (here, the front adhesive film); then one end of the adhesive film 530 is lifted and placed on the repair component, and clamped by the clamping member 160, thereby peeling the adhesive film 530 upward to expose the battery string 520. At the same time, the position of the repair component on the bracket body 100 can be adjusted according to the part of the battery string 520 to be repaired, thereby adjusting the area of ​​the peeled adhesive film 530, and thus adjusting the area of ​​the exposed battery string 520. For example, if the edge of the battery string 520 is to be repaired, the repair component can be moved closer to that edge. At the edge, the battery string at that edge needs to be exposed. If the middle part of the battery string 520 needs to be repaired, the repair component can be moved closer to the middle part to at least expose the middle part. In general, the part of the battery string 520 that needs to be repaired can be exposed by adjusting the position of the repair component. Finally, by using the second support position 300 on the repair component, one end of the battery string 520 can be lifted up and folded to expose the part to be repaired. Then, the folded part of the battery string 520 is placed on the second support position 300 of the repair component so that the part to be repaired is exactly located on the second support position 300. Then, the damaged part of the battery string 520 can be repaired specifically on the second support position 300.

[0054] This support device allows the glass, encapsulant film 530, battery string 520, and other components of the photovoltaic module (back film, backsheet, etc.) to be placed on the same device during photovoltaic module repair, reducing the handling of individual components and lowering the risk of damage caused by handling. Furthermore, by partially folding the battery string 520 and placing it on the second support position 300, damage to the batteries caused by repair personnel bending over the battery string 520 during repairs can be avoided.

[0055] In one embodiment, see Figure 1As shown, the support body 100 includes a first split support 110, a second split support 120, and a movable connecting component 130. The movable connecting component 130 connects the first split support 110 and the second split support 120 and is used to adjust the relative position between the first split support 110 and the second split support 120.

[0056] In this embodiment, the support body 100 includes a first split support 110, a second split support 120, and a movable connecting assembly 130. The first split support 110 and the second split support 120 are located on opposite sides of the photovoltaic module's width. The movable connecting assembly 130 telescopically connects the first split support 110 and the second split support 120, making their relative positions adjustable. By adjusting the relative positions of the first split support 110 and the second split support 120, the load-bearing space of the support body 100 can be adjusted according to changes in the photovoltaic module's size. This allows the support device to adapt to and support photovoltaic modules of different specifications for maintenance, improving the device's dimensional adaptability during pre-lamination repair processes.

[0057] Furthermore, in one embodiment, see [reference] Figure 1 and Figure 2 As shown, the movable connection assembly 130 includes: a first adjusting plate 131 fixedly mounted on the first split bracket 110; the first adjusting plate 131 has an adjusting groove 1312; the adjusting groove 1312 has a first adjusting channel 1311 extending through the first adjusting plate 131 along the thickness direction; both the adjusting groove 1312 and the first adjusting channel 1311 extend along the length direction of the first adjusting plate 131; and the end of the adjusting groove 1312 facing the second adjusting plate 132 is open; the second adjusting plate 132 is fixedly mounted on the second split bracket 120; the second adjusting plate 132 has an adjusting part 1321; the adjusting part 1321 protrudes from one end of the second adjusting plate 132 in the direction facing the first adjusting plate 131; the adjusting part 1321 has a second adjusting channel 1322 extending through the second adjusting plate 132 along the thickness direction; and a fastener 133 is used to lock the second adjusting channel 1322 at a predetermined position in the first adjusting channel 1311.

[0058] The adjusting groove 1312 is used to accommodate the adjusting part 1321, which can slide along the width direction of the photovoltaic module within the adjusting groove 1312 to adjust the distance between the first split bracket 110 and the second split bracket 120. When the adjusting part 1321 is accommodated in the adjusting groove 1312, the first adjusting channel 1311 and the second adjusting channel 1322 are aligned vertically to facilitate locking of the fastener 133.

[0059] In this embodiment, the depth of the adjusting groove 1312 matches the thickness of the adjusting part 1321, for example, they are equal, so that the adjusting part 1321 can fit well in the adjusting groove 1312, and the upper surface of the adjusting part 1321 is flush with the upper surface of the first adjusting plate 131. The thickness of the second adjusting plate 132 is equal to the thickness of the first adjusting plate 131 and greater than the thickness of the adjusting part 1321.

[0060] In this embodiment, a first adjusting plate 131 is fixedly mounted on a first split bracket 110, and an adjusting groove 1312 and a first adjusting channel 1311 are formed on the first adjusting plate 131. Simultaneously, a second adjusting plate 132 is fixedly mounted on a second split bracket 120, and a protruding adjusting part 1321 is provided at one end of the second adjusting plate 132, with a second adjusting channel 1322 provided therein. Through the cooperation of the adjusting part 1321 and the adjusting groove 1312, and the mutual cooperation of the first adjusting channel 1311 and the second adjusting channel 1322, an adjusting structure is formed. A fastener 133 is used to lock the second adjusting channel 1322 in a predetermined position within the first adjusting channel 1311, thereby achieving the adjustment and locking of the relative position between the first split bracket 110 and the second split bracket 120.

[0061] In one embodiment, see Figure 1 As shown, the first split bracket 110 includes a first support plate 111 and a second support plate 112 arranged in parallel and spaced apart, and a first connecting plate 113 connecting the first support plate 111 and the second support plate 112. The first support plate 111 and the second support plate 112 extend longitudinally and are located on opposite sides of the photovoltaic module along its length. The first connecting plate 113 extends along the length of the photovoltaic module and connects the bottom ends of the first support plate 111 and the second support plate 112. The second split bracket 120 includes a third support plate 121 and a fourth support plate 122 arranged in parallel and spaced apart, and a second connecting plate 123 connecting the third support plate 121 and the fourth support plate 122. The third support plate 121 and the fourth support plate 122 extend longitudinally and are located on opposite sides of the photovoltaic module along its length. The second connecting plate 123 extends along the length of the photovoltaic module and connects the bottom ends of the third support plate 121 and the fourth support plate 122. A movable connecting assembly 130 connects the first connecting plate 113 and the second connecting plate 123.

[0062] In this embodiment, the first split bracket 110 is configured to include a first support plate 111 and a second support plate 112 arranged in parallel and spaced apart, and connected to the first support plate 111 and the second support plate 112 by a first connecting plate 113. Simultaneously, the second split bracket 120 is configured to include a third support plate 121 and a fourth support plate 122 arranged in parallel and spaced apart, and connected to the third support plate 121 and the fourth support plate 122 by a second connecting plate 123. This allows the first split bracket 110 and the second split bracket 120 to form a structurally stable frame. An adjustable connection between the first connecting plate 113 and the second connecting plate 123 is achieved by connecting the first connecting plate 113 and the second connecting plate 123 via a movable connecting assembly 130, providing relative position adjustment functionality while ensuring structural stability.

[0063] In one embodiment, see Figure 1 As shown, the edge of the first connecting plate 113 facing the second split bracket 120, the edge of the second connecting plate 123 facing the first split bracket 110, and the movable connecting assembly 130 together form the third bearing position 400.

[0064] In this embodiment, the third bearing position 400 is formed by the cooperation of the edge of the first connecting plate 113 toward the second split bracket 120, the edge of the second connecting plate 123 toward the first split bracket 110, and the movable connecting component 130. The third bearing position 400 formed by the edge and the movable connecting component 130 can support the photovoltaic module on the one hand, and effectively utilize the edge structure of the first connecting plate 113 and the second connecting plate 123 to achieve functional support of the photovoltaic module without adding an additional structure, which helps to improve the structural integration and space utilization efficiency of the bearing device.

[0065] In one embodiment, see Figure 1 and Figure 3 As shown, the first support plate 111 and the second support plate 112 are respectively provided with a bearing plate 140 on the side facing the second split bracket 120; the third support plate 121 and the fourth support plate 122 are respectively provided with a bearing plate 140 on the side facing the first split bracket 110; the multiple bearing plates 140 are at the same height in the vertical direction and are all located at the top of the support plate, and the multiple bearing plates 140 together form the first bearing position 200.

[0066] In this embodiment, support plates 140 are respectively provided on the side of the first support plate 111 and the second support plate 112 facing the second split bracket 120, and support plates 140 are respectively provided on the side of the third support plate 121 and the fourth support plate 122 facing the first split bracket 110. The multiple support plates 140 have the same height in the vertical direction, thus forming a first support position 200. Since the multiple support plates 140 have the same height in the vertical direction, the first support position 200 for supporting the glass 510 forms a uniform and flat support surface in structure, effectively improving the flatness stability of the first support position 200. The extension length of the support plate 140 is less than half the minimum length of the movable connecting assembly 130. That is, the support plates 140 on the first split bracket 110 and the support plates 140 on the second split bracket 120 are spaced apart from each other along the width direction of the photovoltaic module, so that after the glass of the photovoltaic module is peeled off, it can be moved from below the support plate 140 to above the support plate 140 through this gap and then placed on the support plate 140.

[0067] In one embodiment, see Figures 3 to 5 As shown, a third connecting plate 114 is disposed between the first support plate 111 and the second support plate 112. The third connecting plate 114 extends along the length direction of the photovoltaic module and is located between the first connecting plate 113 and the carrier plate 140. A fourth connecting plate 124 is disposed between the third support plate 121 and the fourth support plate 122. The fourth connecting plate 124 also extends along the length direction of the photovoltaic module and is located between the second connecting plate 123 and the carrier plate 140. The third connecting plate 114 and the fourth connecting plate 124 are parallel and opposite to each other. The maintenance component includes a rotating shaft 150 disposed between the third connecting plate 114 and the fourth connecting plate 124 and slidable along the length direction of the photovoltaic module. Clamping members 160 are respectively disposed at both ends of the rotating shaft 150, and a second bearing position 300 is rotatably disposed on the rotating shaft 150. The second bearing position 300 is L-shaped and includes: a first bearing surface 310 extending along a first direction, wherein the first direction can be referred to Figure 5 The direction pointed to by arrow a; the second bearing surface 320 extends along the second direction, wherein the second direction can be referred to. Figure 5 The direction pointed to by the middle arrow b, the first direction and the second direction are both perpendicular to the axial direction of the rotating shaft 150; the opening area formed by the first bearing surface 310 and the second bearing surface 320 faces the top of the support body 100.

[0068] In this embodiment, a third connecting plate 114 is provided between the first support plate 111 and the second support plate 112, and a fourth connecting plate 124 is provided between the third support plate 121 and the fourth support plate 122. A slidable rotating shaft 150 is provided between the third connecting plate 114 and the fourth connecting plate 124. Clamping members 160 are respectively provided at both ends of the rotating shaft 150, so that the adhesive film 530 can be clamped and thus peeled up. A second bearing position 300 is rotatably provided on the rotating shaft 150, so that the second bearing position 300 has the ability to rotate and adjust. The second bearing position 300 includes a first bearing surface 310 extending along a first direction and a second bearing surface 320 extending along a second direction. The first bearing surface 310 and the second bearing surface 320 form an opening area, and the central opening area is positioned towards the top of the bracket body 100. By setting the opening area formed by the first bearing surface 310 and the second bearing surface 320 toward the top of the bracket body 100, it is beneficial to realize the top-down placement operation of the battery string 520 during the rework process, thereby improving the placement efficiency of the battery string 520 during the positioning process.

[0069] The clamping component 160 can be a standard clamp that is fixed to the rotating shaft 150.

[0070] In this embodiment, the repair area in the battery string 520 may be located on the front or the back of the battery string 520. Therefore, in actual operation, attention should be paid to the folding direction of the battery string 520 to ensure that the area to be repaired is located on the outside. For example, see... Figure 6 When the repair area is located on the back of the second string 522 of the battery string 520, folding the first string 521 toward the front of the second string 522 will expose the back of the second string 522 to the outside; for example, see Figure 7 When the repair area is located on the front of the third string 523 of the battery string 520, fold the first string 521 and the second string 522 toward the back of the third string 523 so that the front of the third string 523 is exposed to the outside.

[0071] In one embodiment, see Figure 3 and Figure 4 As shown, the third connecting plate 114 is provided with a first moving groove 1141 along the length direction of the third connecting plate 114, and the fourth connecting plate 124 is provided with a second moving groove 1241 along the length direction of the fourth connecting plate 124. The first moving groove 1141 and the second moving groove 1241 are at the same height in the vertical direction and their extension directions are parallel to each other. One end of the rotating shaft 150 is slidably disposed in the first moving groove 1141, and the other end of the rotating shaft 150 is slidably disposed in the second moving groove 1241.

[0072] In this embodiment, a first movable groove 1141 extending along the length of the third connecting plate 114 is provided on the third connecting plate 114, and a second movable groove 1241 extending along the length of the fourth connecting plate 124 is provided on the fourth connecting plate 124. The first movable groove 1141 and the second movable groove 1241 are at the same height in the vertical direction and extend parallel to each other. This allows one end of the rotating shaft 150 to be slidably disposed in the first movable groove 1141 and the other end to be slidably disposed in the second movable groove 1241, thereby enabling the second bearing position 300 to have a slidably adjustable mounting position on the bracket body 100. Through the sliding fit structure between the rotating shaft 150 and the first movable groove 1141 and the second movable groove 1241, the second bearing position 300 can achieve linear position adjustment in addition to rotational adjustment. Furthermore, during rework, the relative position of the second bearing position 300 can be dynamically adjusted according to the size or placement requirements of the battery string 520.

[0073] In one embodiment, the rotating shaft 150 is telescopic along the width direction of the photovoltaic module, and the first bearing surface 310 and the second bearing surface 320 are also telescopic along the width direction of the photovoltaic module. For example, the rotating shaft 150 can be a telescopic rod with telescopic function; the second bearing position 300 is a telescopic L-shaped plate, also with telescopic function; wherein, the two telescopically cooperating parts of the second bearing position 300 are respectively arranged on the two telescopically cooperating parts of the rotating shaft 150. Based on this, the repaired module can be adapted to the repair of photovoltaic modules of different widths, improving versatility.

[0074] In one embodiment, see Figure 5 As shown, a retaining sleeve 330 is fixedly installed on the second bearing position 300, and the retaining sleeve 330 is engaged with the rotating shaft 150.

[0075] In this embodiment, the second bearing position 300 is provided with a retainer 330, which is sleeved on the rotating shaft 150. For example, the rotating shaft 150 is provided with an annular groove at a corresponding position, and the retainer 330 is engaged in the annular groove and can rotate around the annular groove. In this way, the second bearing position 300 can rotate relative to the rotating shaft 150, thereby adjusting the bearing posture of the second bearing position 300.

[0076] In one embodiment, the first split bracket 110, the second split bracket 120, and the rotating shaft 150 are made of resin material.

[0077] In this embodiment, by using resin material to fabricate the first split support 110, the second split support 120, and the rotating shaft 150, the overall weight of the device is reduced while meeting the basic structural strength and stability requirements of the load-bearing device. Furthermore, the resin material has excellent electrical insulation properties, which helps prevent damage to the battery string 520 caused by static electricity buildup or conductivity during rework.

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.

[0079] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
