[0032] The following describes a packaging assembly 100 according to an embodiment of the present utility model with reference to the drawings, which is used for the bag pressing molding of a workpiece to be laminated 200.

[0033] Refer to Figures 1 - 5 As shown, the packaging assembly 100 according to an embodiment of the present utility model may include: a vacuum bag 10, a flow guiding cloth 20, and a suction member 30.

[0034] Specifically, the vacuum bag 10 has a bag cavity 11 for accommodating the workpiece to be laminated 200. The flow guiding cloth 20 is placed inside the vacuum bag 10 and includes a first flow guiding portion 21. At least two sides of the workpiece to be laminated 200 on one side perpendicular to the thickness direction cooperate with the first flow guiding portion 21. The suction member 30 penetrates through the vacuum bag 10 and contacts the flow guiding cloth 20. The suction member 30 is used for evacuating the vacuum bag 10. It should be noted that Figure 1 For illustration only, the first flow guiding portion 21 does not necessarily extend to the edge of the vacuum bag 10, and the orientation of the suction member 30 does not necessarily be parallel to the thickness direction of the workpiece to be laminated 200. Those skilled in the art can select appropriate settings according to needs.

[0035] The workpiece to be laminated 200 may be a photovoltaic module, a printed circuit board (PCB), etc. For example, in some embodiments, such as Figures 1 - 2As shown, the laminate-to-be 200 is a photovoltaic module, which can be used for power generation. The photovoltaic module includes a first glass 210, a photovoltaic chip 230, and a second glass 240 that are stacked in sequence in the front-rear direction. The first glass 210, the photovoltaic chip 230, and the second glass 240 are connected through an adhesive film 220. In some embodiments, the laminate-to-be 200 is a photovoltaic module, which includes glass and a photovoltaic chip that are stacked in sequence, and the glass and the photovoltaic chip are connected through an adhesive film. The photovoltaic chip can be a thin-film battery or a crystalline silicon battery. The adhesive film can be a PVB (polyvinyl butyral) adhesive film, etc.

[0036] Bag molding refers to a method in which a flexible bag (or other flexible diaphragm) is used to receive fluid pressure to uniformly press the workpiece-to-be into a workpiece. The bag molding of the laminate-to-be 200 can be understood as placing the laminate-to-be 200 in a vacuum bag 10 and evacuating the vacuum bag 10 to discharge the gas inside the laminate-to-be 200. For example, in some embodiments, as Figure 2 shown, the gas in the adhesive film 220 is extracted to reduce the bubbles in the adhesive film 220, making the connection between the first glass 210, the photovoltaic chip 230, and the second glass 240 tighter to form a photovoltaic module.

[0037] The vacuum bag 10 can be a plastic bag, a flexible bag, etc. with good sealing performance to reduce the risk of air leakage. For example, in some embodiments, the vacuum bag 10 is a plastic bag, and after placing the laminate-to-be 200 in the bag cavity 11, the plastic bag is heat-sealed, with good sealing performance.

[0038] The cooperation between the flow guide cloth 20 and the laminate-to-be 200 can be contact or partial contact. The flow guide cloth 20 can be a cloth with fine holes to form a flow channel for gas circulation. The flow guide cloth 20 can be bonded to the laminate-to-be 200 through tape, or the flow guide cloth 20 can also be attached to the laminate-to-be 200 by vacuum pumping. The suction member 30 contacts the flow guide cloth 20 so that the suction member 30 can extract the gas in the vacuum bag 10, especially the gas inside the laminate-to-be 200, through the flow channel formed by the flow guide cloth 20.

[0039] The thickness direction of the laminate-to-be 200 can be the stacking direction of the components inside the laminate-to-be 200. One side of the laminate-to-be 200 can cooperate with one, two, three, or more first flow guide parts 21, the two connected sides of the laminate-to-be 200 can cooperate with one first flow guide part 21 together, the three connected sides of the laminate-to-be 200 can cooperate with one first flow guide part 21 together, etc. The cooperation mode between the side of the laminate-to-be 200 and the first flow guide part 21 is not limited, and it is only necessary to make at least two sides of the laminate-to-be 200 cooperate with the first flow guide part 21, with a flexible design.

[0040] For example, in some embodiments, as Figures 1 - 2As shown, the laminated member 200 is a photovoltaic module, the thickness direction of the laminated member 200 is the stacking direction of the first glass 210, the photovoltaic chip 230 and the second glass 240, that is, the front-to-back direction, and the side surface of the laminated member 200 perpendicular to the thickness direction can be the left side surface, the right side surface, the upper side surface or the lower side surface of the laminated member 200. The left side surface, the right side surface, the upper side surface and the lower side surface of the laminated member 200 are respectively matched with a first guide portion 21, and a plurality of connected first guide portions 21 are respectively matched with a plurality of side surfaces of the laminated member 200 to form gas flow channels on a plurality of side surfaces.

[0041] For example, in some embodiments, the portion of the upper side surface of the laminated component 200 close to the right side and the portion of the right side surface close to the upper side are cooperated with a first guide portion 21, that is, a first guide portion 21 is arranged at the upper right corner of the laminated component 200, so that the first guide portion 21 and the two adjacent side surfaces of the laminated component 200 are cooperated to form a "┐" shape.

[0042] For example, in some embodiments, a first guide portion 21 sequentially cooperates with the left side, lower side and right side of the laminated component 200 to form a "U" shape with the three side surfaces of the laminated component 200.

[0043] For example, in some embodiments, a first guide portion 21 cooperates with the left side, lower side, right side and upper side of the laminated piece 200 in sequence and is connected end to end to cooperate with the four side surfaces of the laminated piece 200 to form a "mouth" shape.

[0044] In some related technologies, the photovoltaic module is placed in a vacuum bag and the suction piece is placed on one side of the photovoltaic module. It is difficult to extract the gas near different sides of the photovoltaic module through one suction piece, and the exhaust efficiency of the photovoltaic module is low. In addition, the gas in the photovoltaic module near the side of the photovoltaic module away from the suction piece is not easy to be discharged. For example, the vacuum bag fits the side of the photovoltaic module and blocks the channel through which the suction piece can be used for extraction. The gas in the photovoltaic module is not completely discharged, and the quality of the photovoltaic module is poor. In particular, when the size of the photovoltaic module is large, suction pieces need to be set on different sides of the photovoltaic module. The number of suction pieces is large, the operation is cumbersome, and the cost is high.

[0045] In this application, by providing the flow guiding cloth 20, flow channels are formed to connect the areas near different sides inside the to-be-laminated part 200, enabling the suction part 30 to extract the gas near different sides inside the to-be-laminated part 200 through the flow channels, thereby improving the exhaust efficiency of the to-be-laminated part 200. Moreover, the gas near the side of the to-be-laminated part 200 easily discharges towards the suction part 30 and is then exhausted through the flow channels formed by the first flow guiding part 21. For example, the gas inside the to-be-laminated part 200 near the side away from the suction part 30 discharges through the first flow guiding part 21, so that as much gas as possible inside the to-be-laminated part 200 is discharged or even completely exhausted, and the to-be-laminated part 200 produced has good quality. When the size of the to-be-laminated part 200 is large, the gas near different sides of the to-be-laminated part 200 can also be extracted through the flow guiding cloth 20 and one suction part 30, reducing the number of suction parts 30, simplifying the operation, and lowering the cost.

[0046] For the encapsulation assembly 100 according to the embodiment of the present utility model, by providing the flow guiding cloth 20 including a plurality of connected first flow guiding parts 21, different sides of the to-be-laminated part can be connected, so as to discharge the gas inside the to-be-laminated part near different sides of the to-be-laminated part through the flow guiding cloth 20, improve the exhaust efficiency and the quality of the to-be-laminated part, and is conducive to reducing the number of suction parts 30 and lowering the cost, with better economy.

[0047] In some embodiments, the bag pressing forming of the to-be-laminated part 200 includes two steps: vacuum bag air extraction and autoclave air extraction. The flow guiding cloth 20 can be used in one of the steps, such as the autoclave air extraction step, and the exhaust effect achieved through the flow guiding cloth 20 in the autoclave is better. The flow guiding cloth 20 can also be used in the above two steps, which is conducive to overall improving the exhaust efficiency of the to-be-laminated part 200.

[0048] In some embodiments, as Figures 1 - 2 shown, the flow guiding cloth 20 further includes a second flow guiding part 22, which is used to cooperate with the surface on one side in the thickness direction of the to-be-laminated part 200, and the first flow guiding part 21 is connected to the second flow guiding part 22. By connecting the first flow guiding part 21 through the second flow guiding part 22, the flow channels connecting different sides formed by the first flow guiding part 21 are more stable, the gas flow is smoother, and the exhaust efficiency is improved by utilizing the area of the flow channels formed by the flow guiding cloth 20.

[0049] In some embodiments where there are multiple first flow guiding parts 21, by connecting the multiple first flow guiding parts 21 through the second flow guiding part 22, the connection of the multiple first flow guiding parts 21 is made more firm.

[0050] The second flow guiding part 22 can completely cover the surface on one side in the thickness direction of the to-be-laminated part 200, or the second flow guiding part 22 can also include one, two, three or more flow guiding belts 221 that cooperate with the surface on one side in the thickness direction of the to-be-laminated part 200, with various forms. For example, in some embodiments, as Figures 1 - 2As shown, the second flow guiding portion 22 includes two flow guiding belts 221 which are arranged crosswise, and both ends of each flow guiding belt 221 are respectively connected to a first flow guiding portion 21, so that the four first flow guiding portions 21 respectively cooperate with the four side surfaces of the to-be-laminated member 200. A flow passage can be formed between the four side surfaces of the to-be-laminated member 200 and one surface on the thickness direction side, which is beneficial to exhausting the gas inside the to-be-laminated member 200 at the four side surfaces of the to-be-laminated member 200 through a suction member 30, and has a better effect of improving the exhaust efficiency and reducing the cost. The two crosswise arranged flow guiding belts 221 can be configured in a "cross" shape, an "X" shape, etc.

[0051] In some embodiments, the second flow guiding portion 22 includes one flow guiding belt 221, and at least one first flow guiding portion 21 is connected to any one end of the flow guiding belt 221, so that the first flow guiding portions 21 connected to the flow guiding belt 221 respectively cooperate with the four side surfaces of the to-be-laminated member 200. A flow passage can be formed between the four side surfaces of the to-be-laminated member 200 and one surface on the thickness direction side, the exhaust efficiency is relatively high, and it is beneficial to reduce the size of the flow guiding cloth 20, and the economy is good. The design of the second flow guiding portion 22 is relatively flexible.

[0052] For example, in some embodiments, the flow guiding belt 221 extends along the diagonal line of the to-be-laminated member 200 to cooperate with the front surface of the to-be-laminated member 200, and one first flow guiding portion 21 is respectively connected to both ends of the flow guiding belt 221, and each first flow guiding portion 21 respectively cooperates with two adjacent side surfaces of the to-be-laminated member 200. For example, the flow guiding belt 221 extends from the lower left corner to the upper right corner of the to-be-laminated member 200. The first flow guiding portion 21 at the lower left corner cooperates with the left side surface and the lower side surface of the to-be-laminated member 200 to form an "L" shape, and the first flow guiding portion 21 at the upper right corner cooperates with the right side surface and the upper side surface of the to-be-laminated member 200 to form a "┐" shape.

[0053] For example, in some embodiments, the flow guiding belt 221 extends along the diagonal line of the to-be-laminated member 200 to cooperate with the front surface of the to-be-laminated member 200, and two first flow guiding portions 21 are respectively connected to both ends of the flow guiding belt 221, and the two first flow guiding portions 21 at each end of the flow guiding belt 221 respectively cooperate with two adjacent side surfaces of the to-be-laminated member 200. For example, the flow guiding belt 221 extends from the lower left corner to the upper right corner of the to-be-laminated member 200. One first flow guiding portion 21 at the lower left corner cooperates with the left side surface of the to-be-laminated member 200 and the other first flow guiding portion 21 cooperates with the lower side surface of the to-be-laminated member 200. One first flow guiding portion 21 at the upper right corner cooperates with the right side surface of the to-be-laminated member 200 and the other first flow guiding portion 21 cooperates with the upper side surface of the to-be-laminated member 200.

[0054] The flow guiding cloth 20 can be connected to the to-be-laminated member 200 through an adhesive tape such as a PET (polyethylene terephthalate) tape, and the flow guiding cloth 20 can also be connected to the to-be-laminated member 200 by other means. For example, in some embodiments, such as Figures 1 - 2As shown, the flow guiding cloth 20 further includes a third flow guiding portion 23. The first flow guiding portion 21 is connected to the second flow guiding portion 22 and the third flow guiding portion 23. The third flow guiding portion 23 is used to cooperate with the surface of the to-be-laminated member 200 facing away from the second flow guiding portion 22. The to-be-laminated member 200 is placed flat on a frame such as a tabletop, so that the third flow guiding portion 23 is pressed between the to-be-laminated member 200 and the frame, which can reduce the relative movement between the flow guiding cloth 20 and the to-be-laminated member 200. By evacuating, the flow guiding cloth 20 is adhered to the to-be-laminated member 200, and the flow guiding cloth 20 is not easily separated from the to-be-laminated member 200 by pressing the third flow guiding portion 23 between the to-be-laminated member 200 and the frame, and it is beneficial to increase the area of the flow passage formed by the flow guiding cloth 20 and improve the exhaust efficiency.

[0055] In some embodiments, as Figures 1 - 2 shown, the first flow guiding portion 21, the second flow guiding portion 22 and the third flow guiding portion 23 are integral parts, so that the connectivity of the flow passage formed by the flow guiding cloth 20 at the connection of different flow guiding portions is strong, and it is not easily lost, which is convenient for using together.

[0056] In some embodiments, the thickness of the flow guiding cloth 20 is 1-2 mm. If the thickness is too small, it is easy for the vacuum bag 10 at the flow guiding cloth 20 to be adhered to the to-be-laminated member 200, and the gas flow effect of the flow passage formed by the flow guiding cloth 20 is poor. If the thickness is too large, the space in the vacuum bag 10 connected to the suction member 30 is large, and the gas in the to-be-laminated member 200 is not easily discharged, and the exhaust efficiency is low. Making the thickness of the flow guiding cloth 20 be 1-2 mm is beneficial to meet the exhaust efficiency of the to-be-laminated member 200. For example, the thickness of the flow guiding cloth 20 is 1 mm, 1.5 mm, 2 mm, etc.

[0057] In some embodiments, as Figures 1 - 2 shown, the number of the suction members 30 is one. The suction member 30 is in contact with the first flow guiding portion 21 or the second flow guiding portion 22. The dimension of the suction member 30 along the width direction of the first flow guiding portion 21 or the second flow guiding portion 22 is D1, and the distance between the edge on one side of the width of the second flow guiding portion 22 or the first flow guiding portion 21 and the suction member 30 is D2, and D2≥D1 / 2.

[0058] Here, the width refers to the dimension of the flow guiding cloth 20 perpendicular to the direction of its own length extension. For example, in some embodiments, as Figures 1 - 2 shown, the length of the first flow guiding portion 21 on the right side extends backward, rightward, backward, leftward, and backward in sequence, and its width extends along the up-down direction; the second flow guiding portion 22 with a length extending along the left-right direction has a width extending along the up-down direction; the second flow guiding portion 22 with a length extending along the up-down direction has a width extending along the left-right direction.

[0059] Making D2≥D1 / 2 can make the width of the first diversion part 21 or the second diversion part 22 greater than or equal to 2D1, which is convenient for installing the suction part 30 to make the suction part 30 contact with the diversion cloth 20, and can make the suction part 30 located at a position close to the center in the width direction of the diversion cloth 20, which is beneficial for the suction part 30 to extract gas around at the diversion cloth 20, and the air extraction effect of the suction part 30 is better.

[0060] It should be noted here that during the process of evacuating the vacuum bag 10, the cooperation state between the encapsulation assembly 100 and the workpiece to be laminated 200 may change. For example, the extension state of the first diversion part 21 may change. For example, in some embodiments, as Figures 1 - 2 shown, after evacuating the vacuum bag 10, for the first diversion part 21 on the right side, the front end of the first diversion part 21 is connected to the second diversion part 22 and the rear end is connected to the third diversion part 23. The first diversion part 21 extends backward from the front end and contacts the right side surface of the workpiece to be laminated 200. Then the first diversion part 21 folds and extends to the rear end in sequence to the right, backward, and left, and the folded first diversion part 21 contacts the right side surface of the workpiece to be laminated 200. The folding state of the first diversion part 21 includes but is not limited to this, as long as it can contact the right side surface of the workpiece to be laminated 200. The same applies to the first diversion parts 21 on the left side, upper side, and lower side, which will not be elaborated here.

[0061] For the sake of clear structure, Figures 1 - 2 the vacuum bag 10 in [Figure] is not attached to the workpiece to be laminated 200. Figure 2 In [Figure], two dotted lines are added at the diversion cloth 20 to distinguish the first diversion part 21, the second diversion part 22, and the third diversion part 23. The above two dotted lines respectively correspond to the front surface and the rear surface of the workpiece to be laminated 200, and they are not the structures of the encapsulation assembly 100 and the workpiece to be laminated 200.

[0062] The suction part 30 can be installed at any part that can contact the diversion cloth 20. For example, at the first diversion part 21 on one side surface of the workpiece to be laminated 200 perpendicular to the thickness direction, or at the second diversion part 22 on one surface of the workpiece to be laminated 200 in the thickness direction, and the positions are diverse. For example, in some embodiments, as Figure 1 shown, the suction part 30 is installed on the left side of the workpiece to be laminated 200 and contacts the first diversion part 21, which can reduce the distance between the suction part 30 and the left side surface of the workpiece to be laminated 200, and make the efficiency of the suction part 30 extracting gas from near the side surface of the workpiece to be laminated 200 through the diversion cloth 20 higher.

[0063] In some embodiments, for a photovoltaic module composed of a plurality of photovoltaic chips 230 spliced together, the suction part 30 is arranged near the splicing gap of the photovoltaic module, so as to facilitate the suction part 30 to evacuate the splicing gap of the photovoltaic module, and the exhaust efficiency of the photovoltaic module is higher.

[0064] In some embodiments of the present utility model, as Figures 3 - 5 shown, the suction member 30 has an exhaust passage 351. An exhaust groove 311 is provided on one surface of the suction member 30 facing the flow guide cloth 20, and the exhaust groove 311 communicates with the exhaust passage 351. The exhaust groove 311 can be provided on the end face (for example Figure 5 shown) or the side face in the extending direction of the suction member 30. The exhaust groove 311 can extend in a straight line, in a curve, in a cross shape, etc.

[0065] The gas in the flow passage formed by the flow guide cloth 20 enters the exhaust passage 351 through the exhaust groove 311 and is then discharged. By means of the exhaust groove 311, the exhaust area of the suction member 30 can be increased, which is beneficial to improving the exhaust efficiency of the suction member 30.

[0066] In some embodiments, as Figures 3 - 4 shown, the exhaust groove 311 penetrates the suction member 30 perpendicular to the thickness direction of the flow guide cloth 20, which can increase the communication area between the exhaust groove 311 and the flow guide cloth 20 and directly connect the exhaust groove 311 with the bag cavity 11, facilitating the direct discharge of the gas in the space in the bag cavity 11 that is not in contact with the flow guide cloth 20 and the gas on the part of the flow guide cloth 20 that is not directly opposite to the suction member 30 to the exhaust groove 311 through the bag cavity 11, which is beneficial to further improving the exhaust efficiency of the suction member 30.

[0067] In some embodiments, as Figure 4 shown, the exhaust groove 311 includes a plurality of grooves 312, and the extending directions of at least two grooves 312 are different, which is beneficial to increasing the communication area between the exhaust groove 311 and the flow guide cloth 20. And in some embodiments where the exhaust groove 311 penetrates the suction member 30 perpendicular to the thickness direction of the flow guide cloth 20, the suction member 30 can perform air extraction in multiple directions through the plurality of grooves 312, and the exhaust efficiency is higher.

[0068] In some embodiments of the present utility model, as Figures 3 - 5 shown, the suction member 30 includes a mating part 31, a first seal 32, a second seal 33, a locking member 34 and a suction pipe 35. The mating part 31 is used to contact the flow guide cloth 20. The suction pipe 35 penetrates through the vacuum bag 10 and is fixedly connected to the mating part 31. The locking member 34 is located outside the vacuum bag 10 and is connected to the suction pipe 35. The first seal 32 is located between the mating part 31 and the vacuum bag 10, and the second seal 33 is located between the vacuum bag 10 and the locking member 34. The locking member 34 is movable relative to the suction pipe 35 and is used to press the first seal 32 and the second seal 33.

[0069] The gas inside the vacuum bag 10 can be extracted through the mating part 31 and the air extraction pipe 35. Moreover, by pressing the first seal 32, the vacuum bag 10, and the second seal 33 with the locking member 34, the connection strength and sealing performance between the suction member 30 and the vacuum bag 10 can be improved, the risk of air leakage at the suction member 30 can be reduced, and the exhaust efficiency can be enhanced. The first seal 32 and the second seal 33 can be silicone pads or the like, which have good sealing effects.

[0070] A threaded connection, snap connection, or the like can be provided between the locking member 34 and the air extraction pipe 35. For example, in some embodiments, as Figures 3 - 5 shown, the air extraction pipe 35 includes a locking and mating member 352 and a communication pipe 353 for communicating with an external rubber tube to achieve air extraction. The locking member 34 is a nut with internal threads, and the locking and mating member 352 has external threads that cooperate with the locking member 34. The locking member 34 is threadedly connected to the locking and mating member 352, which has a relatively high connection strength and is convenient for operating the relative movement between the locking member 34 and the locking and mating member 352.

[0071] In some specific embodiments, the mating part 31 and the air extraction pipe 35 are made of steel, and the mating part 31 and the air extraction pipe 35 are welded together, which has a high connection strength.

[0072] In some embodiments, the first seal 32 is bonded to the vacuum bag 10, which is beneficial to improving the sealing effect between the suction member 30 and the vacuum bag 10, and is also beneficial to slowing down the aging rate of the first seal 32 and reducing the risk of air leakage. What can be bonded between the first seal 32 and the vacuum bag 10 can be a water-resistant sealant, a pressure-sensitive rubber ring, or the like, which has a better sealing effect.

[0073] In some embodiments, the second seal 33 is bonded to the vacuum bag 10, which is beneficial to improving the sealing effect between the suction member 30 and the vacuum bag 10, and is also beneficial to slowing down the aging rate of the second seal 33 and reducing the risk of air leakage. What can be bonded between the second seal 33 and the vacuum bag 10 can be a water-resistant sealant, a pressure-sensitive rubber ring, or the like, which has a better sealing effect.
