[0058] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0059] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first demolding jig may be referred to as a second demolding jig, and similarly, a second demolding jig may be referred to as a first demolding jig.

[0060] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0061] The embodiment of the present application provides a material block processing equipment, which is used to process the raw material to be processed into a material block of a target shape. Among them, the raw material to be processed in the embodiment of the present application can be waste generated during the processing of photovoltaic modules. For example, photovoltaic modules with structures such as heterojunction cells (Heterojunction with Intrinsic Thin-layer, HJT) are extremely sensitive to water vapor. Therefore, conventional film packaging methods cannot meet the waterproofing requirements. At present, the most effective packaging method in the industry is edge waterproofing with materials such as butyl rubber, and there is a large amount of butyl rubber wasted in the edge waterproofing process. The material block processing equipment provided in the embodiment of the present application can cut the waste that is collected centrally and is not contaminated by dirt and foreign matter, thereby realizing the recycling and reuse of waste, improving the efficiency of material use, and reducing the production cost of photovoltaic modules.

[0062] Figure 1 This is a schematic diagram of the structure of a material block processing device according to an embodiment, referring to Figure 1 The material block processing device includes a bearing assembly 100, a cutting fixture 200, a pressure assembly 300 and a demoulding assembly 400. For the sake of convenience, the embodiment of the present application takes the material block processing device as an example of being placed in a forward direction, the direction close to the bearing assembly 100 is the downward direction, and the direction away from the bearing assembly 100 is the upward direction.

[0063] The surface of the carrier component 100 facing the cutting jig 200 is used to carry the raw material to be processed. The surface of the carrier component 100 and the raw material to be processed can be separated by a release film 700 to prevent the material blocks formed by cutting from adhering to the surface of the carrier component 100.

[0064] The cutting jig 200 is provided with a plurality of cutting grooves. The number of the cutting grooves may be 10, 20, 50, 100, etc. The depth of the cutting groove may be the same as the overall thickness of the cutting jig 200, that is, the cutting groove runs through the thickness direction of the cutting jig 200. The depth of the cutting groove may also be less than the overall thickness of the cutting jig 200. The shape of the projection of the cutting groove along the thickness direction of the cutting jig 200 may be any one of regular shapes such as a square, a rectangle, a circle, or an irregular shape. The size of the projection of the cutting groove along the thickness direction of the cutting jig 200 may be 10 mm to 30 mm, for example, 10 mm, 15 mm, 20 mm or 30 mm. It is understandable that the depth, shape and size of the cutting groove may be set corresponding to the material block to be formed, and are not limited here. In addition, the material block processing equipment may include a plurality of detachably connected cutting jigs 200, so that corresponding cutting jigs 200 can be selected and assembled according to different usage scenarios to enhance the flexibility of the material block processing equipment.

[0065] The pressure-applying assembly 300 is used to move in a direction close to the bearing assembly 100 to apply pressure to the cutting jig 200. That is, the pressure-applying assembly 300 is used to move in a downward direction to apply pressure to the cutting jig 200. Under the action of the pressure-applying assembly 300, the cutting jig 200 can contact the raw material to be processed and press the raw material to be processed into the cutting groove, thereby cutting the raw material to be processed into a plurality of blocks corresponding to the cutting groove.

[0066] The demoulding component 400 is used to act on the material block and / or the cutting jig 200 to separate the material block from the cutting jig 200 after the cutting of the material block is completed. That is, the demoulding component 400 can act only on the material block, or only on the cutting jig 200, or can act on the material block and the cutting jig 200 separately. As long as the demoulding component 400 can separate the material block from the cutting jig 200, it belongs to the protection scope of this embodiment. It can be understood that the raw materials to be processed usually have certain viscoelastic properties, which are easy to stick to the cutting jig 200 and cannot be peeled off. However, the efficiency of manually peeling the material block is low, and the material block is easy to be pulled and deformed. Therefore, the demoulding component 400 used in this embodiment to separate the material block from the cutting jig 200 can effectively ensure the shape reliability of the removed material block, and can realize the batch removal of the material block, thereby improving the production efficiency of the material block. It should be noted that Figure 1 The demolding assembly 400 including the ejector pins is shown for exemplary purposes only, and the demolding assembly 400 may also be implemented in other ways.

[0067] In the embodiment of the application, based on the multiple cutting grooves in the cutting fixture 200, multiple blocks corresponding to the number and shape of the cutting grooves can be formed in batches through the extrusion of the pressure component 300, provided that a sufficient amount of raw materials to be processed are provided. Moreover, by stripping the blocks from the cutting fixture 200 through the demolding component 400, the shape reliability of the stripped blocks can be effectively improved, and the production efficiency of the blocks can be improved. In the case where the raw materials to be processed are waste materials, the block processing equipment of this embodiment can realize the recycling and reuse of waste materials, thereby improving the use efficiency of materials and reducing the production cost of photovoltaic modules.

[0068] In one embodiment, the pressure assembly 300 includes a motor 310, a pressure table 320 and a movable crossbeam 330. The movable crossbeam 330 is connected to the motor 310 and the pressure table 320 respectively, and the movable crossbeam 330 is used to extend and contract under the drive of the motor 310 to drive the pressure table 320 to move. Further, the movable crossbeam 330 includes a first crossbeam and a second crossbeam sleeved on the periphery of the first crossbeam, and the first crossbeam is movably connected to the second crossbeam. The end of the first crossbeam away from the bearing assembly 100 is connected to the motor 310, and the end of the second crossbeam close to the bearing assembly 100 is connected to the pressure table 320. The motor 310 can control the length of the first crossbeam exposed to the outside of the second crossbeam, so as to adjust the extension and contraction of the movable crossbeam 330. It should be noted that the movable crossbeam 330 can also be extended and contracted in other ways in the relevant technology, which is not limited here.

[0069] In one embodiment, the material block processing equipment further includes an upper crossbeam 620 and a plurality of columns 610. One end of the column 610 is connected to the bearing assembly 100, and the upper crossbeam 620 is respectively connected to the other ends of the plurality of columns 610, and the upper crossbeam 620 is used to fix the motor 310. Furthermore, the pressure table 320 is also provided with a plurality of positioning holes (not shown), and the plurality of positioning holes are respectively arranged corresponding to the plurality of columns 610, so that the pressure table 320 reciprocates along the extension direction of the columns 610.

[0070] In one embodiment, the raw material to be processed is a thermoplastic material. A thermoplastic material refers to a material that can soften and flow when heated and can maintain a certain shape after cooling. Exemplarily, thermoplastic materials include but are not limited to ethylene-vinyl acetate copolymer (EVA), butyl rubber, etc. Correspondingly, the bearing component 100 includes a base 110 and a heating table 120. Among them, the heating table 120 is arranged on the surface of the base 110, and the side of the heating table 120 facing the pressure component 300 is used to carry the raw material to be processed. Among them, the heating table 120 may include a workbench 121 and a heating wire 122 arranged inside the workbench 121. Specifically, the heating table 120 can soften the raw material to be processed. In the process of applying pressure by the pressure component 300, the softened raw material to be processed is easier to be pressed into the cutting fixture 200 and cut into blocks, thereby reducing the pressure required to be applied by the pressure component 300, and reducing the incompleteness of the blocks caused by the incomplete pressing of the raw material to be processed into the cutting fixture 200, effectively improving the success rate of block cutting.

[0071] In one embodiment, the demoulding assembly 400 includes an ejector pin 410 and a first demoulding fixture 420. The ejector pin 410 is disposed on the carrier assembly 100. A groove (not shown) may be disposed on the side of the carrier assembly 100 facing the pressure assembly 300, and the groove is used to accommodate at least part of the ejector pin 410. During the block cutting process, the ejector pin 410 is located at Figure 1 In the first position shown, the ejector pin 410 is fully or partially accommodated in the groove. The top of the ejector pin 410 in the first position is lower than the top of the cutting jig 200 to prevent the pressure component 300 from damaging the ejector pin 410 during movement. The figure is a schematic diagram of the second position of the ejector pin 410 of the material block processing equipment of one embodiment. Referring to the figure, after the cutting of the material block is completed, the ejector pin 410 is used to move upward from the groove to the second position so that the ejector pin 410 is at least partially exposed to the surface of the bearing component 100. Further, the ejector pin 410 continues to move in a direction away from the surface of the bearing component 100, abuts against the cutting jig 200 and lifts the cutting jig 200, so that the cutting jig 200 is separated from the surface of the bearing component 100. The first demolding jig 420 is used to abut against the side of the material block away from the bearing component 100, and move in a direction close to the bearing component 100 to separate the material block from the cutting jig 200.

[0072] Specifically, during the processing of the material block, the cutting jig 200 can be placed on the surface of the material to be cut, and the pressure component 300 can be controlled to move downward to press the cutting jig 200 into the material to be cut, so as to cut the material to be cut. After the cutting of the material block is completed, the pressure component 300 is controlled to move upward to the surface of the cutting jig 200 and keep a certain distance from the surface of the cutting jig 200. Then, after the first demolding jig 420 is assembled to the pressure component 300, the ejector pin 410 and the pressure component 300 are controlled to move relative to each other. That is, the ejector pin 410 pushes the cutting jig 200 upward, the pressure component 300 moves downward, and drives the first demolding jig 420 to push the cut material block downward. Among them, after the ejector pin 410 pushes the cutting jig 200 up, the distance between the lower surface of the cutting jig 200 and the surface of the bearing component 100 can be greater than the thickness of the cutting jig 200. By setting the height as described above, the material block can be completely released from the cutting jig 200 under the action of the first demolding jig 420 , thereby reducing the adhesion between the material block and the cutting jig 200 to a greater extent.

[0073] Figure 3 The three views of the first demoulding fixture 420 of an embodiment are shown in FIG. Figure 3 In one embodiment, the first demolding jig 420 includes a first bottom plate 421 and a plurality of protrusions 422. The plurality of protrusions 422 are connected to the surface of the first bottom plate 421 and are arranged corresponding to the cutting grooves of the cutting jig 200. The protrusions 422 are used to abut against a side of the material block away from the bearing assembly 100, so that when the first demolding jig 420 moves in a direction close to the bearing assembly 100, the material block is pushed out of the cutting jig 200. Exemplarily, the plurality of protrusions 422 can be arranged one-to-one corresponding to the plurality of cutting grooves, respectively, and one protrusion 422 is used to push out the material block in a corresponding cutting groove. In another exemplary embodiment, one protrusion 422 can correspond to a plurality of cutting grooves, and one protrusion 422 is used to synchronously push out the material blocks in the corresponding plurality of cutting grooves.

[0074] In one embodiment, the demolding assembly 400 includes a second demolding fixture 430 and an elastic element 440 . Figure 4 FIG. 1 is a working schematic diagram of a demoulding assembly 400 including a second demoulding fixture 430 according to an embodiment of the present invention. Figure 5 FIG. 2 is a second working schematic diagram of a demoulding assembly 400 including a second demoulding fixture 430 according to an embodiment of the present invention, with reference to FIG. Figure 4 and Figure 5 The two ends of the elastic element 440 are respectively connected to the second demoulding jig 430 and the cutting jig 200. The elastic element 440 may include, but is not limited to, a spring, a spring sheet, and the like.

[0075] When the pressure applying component 300 does not apply pressure, the elastic component is in Figure 5 The elastic element 440 is used to compress when the pressure component 300 moves in a direction close to the bearing component 100, that is, it is presented as Figure 4 The state shown. Specifically, during the process of cutting and forming blocks, the pressure component 300 moves in a direction close to the load-bearing component 100, and causes the second demolding jig 430 to move downward under the action of the pressure component 300, so that the elastic element 440 is compressed. The elastic force of the elastic element 440 acts on the cutting jig 200, causing the cutting jig 200 to contact the raw material to be processed, and press the raw material to be processed into the cutting groove, thereby cutting the raw material to be processed into a plurality of blocks corresponding to the cutting groove. The elastic element 440 is also used to expand when the pressure component 300 moves in a direction away from the load-bearing component 100, that is, to restore to Figure 5 The state shown is to push the block out of the cutting jig 200. Specifically, when the pressure assembly 300 moves up to expand the elastic element 440, the force released by the elastic element 440 can act on the cutting jig 200 and cause the block in the cutting jig 200 to pop out.

[0076] In one embodiment, the material block processing equipment further includes a thickness jig 500, and the thickness jig 500 has a preset thickness. The pressure component 300 is also used to process the raw material to be processed into a sheet with a preset thickness through the thickness jig 500, and to cut the sheet into a plurality of material blocks corresponding to the cutting grooves through the thickness jig 500. Specifically, the thickness jig 500 may include a first frame that is closed circumferentially, and the thickness of the first frame is 1mm to 3mm. Exemplarily, the thickness of the first frame is 1mm, 1.5mm, 2mm, 2.5mm, 3mm.

[0077] Optionally, Figure 6 FIG. 5 is a schematic diagram of a thickness jig 500 according to an embodiment of the present invention. Figure 6, the raw material to be processed can be placed on the surface of the bearing component 100 first, and then the thickness jig 500 is placed, and the pressure component 300 is controlled to move downward to apply pressure to the raw material to be processed, so as to process the initial raw material to be processed into a sheet. The thickness jig 500 can also be placed on the surface of the bearing component 100 first, and then the raw material to be processed is placed in the thickness jig 500, and the pressure component 300 is controlled to move downward to apply pressure to the raw material to be processed, so as to process the initial raw material to be processed into a sheet. The processing method of this embodiment of first processing the raw material to be processed into a sheet and then cutting it into blocks can reduce the situation where the raw material to be processed is locally too thick and causes uneven cutting of the blocks, so that the multiple blocks formed by cutting have the same or similar thickness, thereby facilitating the subsequent use of the blocks. Furthermore, the thickness jig 500, the first demoulding jig 420 and the second demoulding jig 430 are all detachably connected to the pressure component 300. In the cutting stage of the sheet, the thickness jig 500 can be assembled at the lower end of the pressure component 300. Accordingly, the assembled thickness jig 500 can be disassembled and the first demolding jig 420 can be assembled during the demolding stage of the block. Alternatively, the assembled thickness jig 500 can be disassembled and the second demolding jig 430 can be assembled during the cutting stage of the block.

The first dividing strips 220 and the second dividing strips 230 are connected to the second bottom plate 210 and cross-arranged to separate and form a cutting groove.

[0079] Furthermore, the cutting jig 200 also includes a plurality of opening pieces 240. The plurality of opening pieces 240 are connected to the second base plate 210, and the plurality of opening pieces 240 are respectively arranged corresponding to the plurality of cutting grooves, and the opening piece 240 is used to form a first opening of the material block in the thickness direction during the cutting process. Among them, the opening piece 240 includes two long strip-shaped structural members 241 extending along a first direction, and the first direction is parallel to the extension direction of the first separator 220 or the second separator 230. The first opening of the material block is used to lead out the bus bar of the photovoltaic module. Specifically, the second base plate 210 may include a circumferentially closed second frame and a plurality of fixing bars for connecting the opening piece 240. The extension direction of the fixing bar is parallel to the extension direction of the first separator 220 or the second separator 230, and the extension direction of the fixing bar may be different from the extension direction of the long strip structural member 241. The two ends of the fixing bar are respectively connected to the second frame, and the thickness of the fixing bar is the same as the thickness of the circumferentially closed second frame. Taking the example that the extension direction of the fixing strip is parallel to the extension direction of the first dividing strip 220 , the two ends of the second dividing strip 230 are respectively connected to the second frame, and the middle of the second dividing strip 230 is connected to multiple fixing strips arranged in parallel to improve the connection stability of the second dividing strip 230 .

[0080] The embodiment of the present application also provides a packaging material block, which is made by using the material block processing equipment as described above.

[0081] The embodiment of the present application also provides a photovoltaic module, including a packaging material block as described above, a first glass, a second glass, and a plurality of solar cells arranged between the first glass and the second glass, wherein the plurality of solar cells are connected by a bus bar. Among them, the second glass is provided with a second opening for leading out the bus bar, and the packaging material block is arranged on the side of the second glass close to or away from the solar cell, for sealing the second opening. The side methyl groups of the molecular chain of butyl rubber are densely arranged and arranged regularly, which limits the thermal motion of the molecules, so the air permeability is low and the air tightness is good. It can be understood that because the amount of the material block is small, and the photovoltaic module will be heated and vacuumed again during lamination, in the process of collecting waste materials and processing them into material blocks, it is only necessary to control the appearance of the waste materials and the storage conditions, without the need for impurity removal and exhaust, and the process is simple and stable. Therefore, the material block processing equipment as described above is used to make the material block for waterproofing the hole position of the photovoltaic module, which can improve the reliability of the photovoltaic module. Moreover, compared with the purchased material blocks, recycling the self-made material blocks can reduce the cost by about 6 million yuan per GW production capacity according to the current market conditions.

[0082] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0083] The above embodiments only express several implementation methods of the embodiments of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the embodiments of the present application, and these all belong to the protection scope of the embodiments of the present application.
