[0036] The present application embodiment provides a curing device, Figure 1 A schematic structural diagram of a curing device provided in one embodiment of the present application is shown. Figure 2 A schematic structural diagram of a curing device provided in another embodiment of the present application is shown. Figure 3 A schematic structural diagram of a curing device provided in yet another embodiment of the present application is shown. Figure 4 Another structural schematic diagram of a curing device provided in yet another embodiment of the present application is shown. Figure 5 A partial structural schematic diagram of a curing device provided in yet another embodiment of the present application is shown. Figure 6 A schematic diagram of the structure of the lifting mechanism of a curing device provided in another embodiment of the present application is shown. Figures 1 to 6 As shown, the curing equipment provided in the embodiment of the present application cures the laminated part 300 after lamination, and the laminated part 300 includes photovoltaic cells, adhesive films and glass. The adhesive films and glass are used to encapsulate the photovoltaic cells so that the photovoltaic cells have the ability to resist interference from the external environment and improve the stability of the photovoltaic cells. After the photovoltaic cells, adhesive films and glass are laminated, the three are compacted firmly to form a laminated part 300 with an integral structure. An aluminum frame is added to the laminated part 300 to encapsulate the four sides of the laminated part 300, and then the laminated part 300 is cured so that the adhesive film in the laminated part 300 undergoes a cross-linking reaction, thereby improving the adhesion between the adhesive film and other structures. Among them, during the curing process, the more uniform the curing is, the more it can complete the curing in the shortest time and have a good curing effect.

[0037] The curing device provided in the embodiment of the present application can make the heat applied to the adhesive film in the laminate 300 uniform, thereby achieving uniform curing and improving the curing efficiency.

[0038] like Figure 1 As shown, the curing device provided in the embodiment of the present application includes a carrier 110. The carrier 110 is used to carry the laminate 300 to be cured.

[0039] The carrier 110 has a containing tank containing liquid 200 at a target temperature; the laminate 300 to be cured is placed in the containing tank, and the liquid 200 at least covers the first surface of the laminate 300, which is the side close to the bottom of the containing tank.

[0040] The bearing member 110 has a receiving groove, which can be a receiving groove grooved in a thick plate, or can be formed by fixing the edge of a plate as a bottom plate and surrounding a circle of side walls. The bearing member 110 can be fixed on the frame 130 to facilitate the operation of the staff.

[0041] The holding tank contains the liquid 200 of the target temperature. The laminate 300 to be cured is a structure in which multiple layers are closely attached to each other after lamination and an aluminum frame is added. Therefore, placing the laminate 300 in the liquid 200 for a short time will not cause water vapor to penetrate. Based on this, when the laminate 300 is cured, by placing the laminate 300 in the liquid 200 of the target temperature, the laminate 300 can receive the heat transferred by the liquid 200, so that the adhesive film is cured after being heated.

[0042] The liquid 200 at least covers the first surface of the laminate 300 , so that the liquid 200 at the target temperature contacts the laminate 300 , facilitating rapid heat transfer to the laminate 300 .

[0043] In addition, in other embodiments, the laminate 300 may not contact the liquid 200, and the receiving tank may be an inverted cone structure (narrow at the bottom and wide at the top), so that the laminate 300 may be installed in the receiving tank, and the laminate 300 may not contact the liquid 200, but the liquid 200 at the target temperature may be transferred to the laminate 300 by means of water vapor or the like. It is understood that this implementation is also within the protection scope of the embodiments of the present application.

[0044] The adhesive film inside the laminate 300 can be an EVA (Polyethylene vinylacetate) film, a POE (Polyolefin Elastomer) film, or an EPE (Ethylene Vinyl Acetate) film, etc. The present embodiment of the application does not limit the material of the adhesive film. For adhesive films of different materials, the target temperature of the liquid 200 in the containing tank can be adapted thereto.

[0045] As an example, the ideal curing temperature of EVA film is 60°C-85°C. When the film used in the laminate 300 is EVA film, the target temperature of the liquid 200 can be any value between 60°C-85°C.

[0046] As another example, the ideal curing temperature of POE adhesive film is generally between 80-120° C., and when the adhesive film used in the laminate 300 is a POE adhesive film, the target temperature of the liquid 200 can be any value between 80° C. and 120° C.

[0047] In another example, the adhesive film is an EPE adhesive film, and the ideal curing temperature of the EPE adhesive film is 70°C-90°C. When curing the laminate 300 containing the EPE adhesive film, the target temperature of the liquid 200 can be between 70°C-90°C. In actual application, the target temperature of the liquid 200 can be set according to the specific situation.

[0048] As an example, commonly used encapsulation films for photovoltaic cells include EVA films and POE films. The target temperature of the liquid 200 can be defaulted to a temperature that is compatible with both the EVA film and the POE film, such as any value between 80°C and 90°C, so that no matter what material the photovoltaic cell is encapsulated with, the liquid 200 at the target temperature can be applied without making additional adjustments based on the film material, thereby increasing the versatility of application of the curing equipment and improving the curing efficiency of the laminate 300.

[0049] In the embodiment of the present application, by containing the liquid 200 of the target temperature in the containing tank, so that the liquid 200 of the target temperature can transfer heat to the laminate 300, based on the fluidity of the liquid 200, it can be ensured that multiple different positions of the laminate 300 are heated evenly, so that the adhesive film at multiple different positions in the laminate 300 undergoes the same degree of cross-linking reaction, thereby achieving uniform curing.

[0050] By using the curing equipment provided in the embodiment of the present application to achieve uniform curing of the laminate 300, the degree of bonding of the adhesive film inside the battery after curing can be uniform, and no obvious shrinkage will occur after curing.

[0051] In one embodiment, the curing device further includes a light source assembly 120 .

[0052] The embodiment of the present application uses a light-curing method to cure the laminate. In the light-curing method, the adhesive film in the laminate 300 is irradiated by a light source, and is subjected to the heat of the light source assembly 120 and the heat of the carrier 110, which promotes the curing of the adhesive film to form a solid adhesive film that is tightly bonded to the photovoltaic cell or glass. The heat transferred by the carrier 110 to the laminate 300 can increase the speed of the cross-linking reaction and improve the curing efficiency, so that the adhesive film can be cured within a few seconds; during the curing process, the light source assembly 120 simultaneously irradiates the light source from above to the laminate 300, which can change the structure and physical and chemical properties of the internal materials of the photovoltaic cell, making it more suitable for the operation of the photovoltaic cell, thereby improving the power generation efficiency and stability of the photovoltaic cell.

[0053] The light source assembly 120 is located above the carrier 110, and the light source assembly 120 emits light to irradiate the receiving groove. When the laminate 300 is placed in the receiving groove, the light source acts on the adhesive film inside the laminate 300. The light source emitted by the light source assembly 120 can be an ultraviolet light source, an infrared light source, or an LED light source.

[0054] In one embodiment, the liquid 200 covers at least the second surface of the laminate 300, the second surface being the side opposite to the first surface.

[0055] In one example, the first surface is the back side of the laminate 300 , and the second surface is the front side of the laminate 300 .

[0056] Since the laminate 300 has been laminated and aluminum framed, the laminate 300 can be completely immersed in the liquid 200 during the curing process, and conduct heat to the front adhesive film located on the front of the photovoltaic cell and the back adhesive film located on the back of the photovoltaic cell at a faster and more uniform speed, so that the front adhesive film and the back adhesive film are simultaneously subjected to the same heat transfer, promoting the simultaneous curing of the two adhesive films of the laminate 300.

[0057] In one embodiment, the height difference between the liquid surface of the liquid 200 and the second surface is 0-5 cm.

[0058] The laminate 300 is completely immersed in the liquid 200 in the containing tank, and the surface of the liquid 200 can be higher than the second surface of the laminate 300. However, if the height difference is too large, it will lead to an increase in the volume of the liquid 200, which will increase the cost. In addition, when the temperature of the liquid 200 changes, the burden of the temperature regulation operation will be increased, which will reduce the efficiency of the temperature regulation.

[0059] In one embodiment, the carrier 110 is provided with a liquid inlet 112 and a liquid outlet 111 ; the liquid inlet 112 and the liquid outlet 111 both penetrate into the containing tank; the liquid 200 at the target temperature enters the containing tank from the liquid inlet 112 and flows out from the liquid outlet 111 .

[0060] As an example, the solidification device further includes a water pump 113 to recover the liquid 200 flowing out of the liquid outlet 111 and, after heating the recovered liquid 200 to a target temperature, pump the liquid 200 to the liquid inlet 112 to replenish the liquid 200 in the containing tank.

[0061] In the embodiment of the present application, the temperature of the liquid 200 in the containing tank is maintained at the target temperature by continuously inputting the liquid 200 at the target temperature into the containing tank, thereby ensuring that the laminate 300 is completed at the ideal temperature.

[0062] The liquid inlet 112 and the liquid outlet 111 may be disposed on the side of the carrier 110 , or may be disposed on the bottom of the carrier 110 .

[0063] In one embodiment, a heating device is further included. The heating device is located in the containing tank and is arranged at the bottom of the containing tank. The heating device is used to heat the liquid 200 to a target temperature.

[0064] In the embodiment of the present application, the liquid 200 in the containing tank is heated by a heating device so that the liquid 200 in the containing tank reaches a target temperature without continuously injecting the liquid 200.

[0065] In the embodiment of the present application, a heating device is disposed in the containing tank to directly heat the liquid 200 , and the heating device may be an electric heating rod or a resistance wire.

[0066] In the embodiment of the present application, the liquid 200 in the containing tank is heated, and then the heat of the liquid 200 is transferred to the laminate 300. Based on the fluidity of the liquid 200, the temperature distribution of the liquid 200 is uniform, thereby ensuring that the heat transferred to the laminate 300 is uniform.

[0067] In one embodiment, a heating device is further included. The heating device is located below the carrier 110 and is used to heat the carrier 110. The carrier 110 conducts heat to the liquid 200 to heat the liquid 200 to a target temperature.

[0068] In the embodiment of the present application, the heating device heats the carrier 110 below the carrier 110, and the carrier 110 then transfers heat to the receiving groove. The heating device can be a resistance wire heating or an open flame heating.

[0069] In one embodiment, a temperature sensor is further included, and the temperature sensor is used to detect the temperature of the liquid 200 so that the temperature of the liquid 200 is maintained within an error threshold of a target temperature, wherein the target temperature is 70-90°C and the error threshold is ±5°C.

[0070] The target temperature is set based on the cross-linking reaction requirements of the film. The target temperature can be a specific specified value, such as 80°C. When performing temperature control, based on its error threshold of ±5°C, it can be determined that the temperature of the liquid 200 is within the range of 75°C and 85°C, which meets the requirements.

[0071] In one embodiment, liquid 200 includes water.

[0072] Any liquid 200 whose boiling point is not lower than the target temperature can implement the solution of the embodiment of the present application.

[0073] Preferably, the liquid 200 may be water, the boiling point of which meets the cross-linking and curing requirements of the EVA film and the POE film, and the liquid 200 is low in cost, will not contaminate the laminate 300 , and is easily available.

[0074] In one embodiment, if Figure 2As shown, the curing device also includes a conveyor 400, which drives the laminate 300 to move from the first device 500 to the receiving tank, and then moves from the receiving tank to the second device 600; the first device 500 includes a preheating device; the second device 600 includes a cooling and drying device.

[0075] The curing device provided in the embodiment of the present application is used to achieve uniform curing of the laminate 300 during the preparation of the photovoltaic cell module. Before the photovoltaic cell module is prepared, there are many other processes in the early and late stages of curing, such as preheating the laminate 300 before curing; cooling and drying the laminate 300 after curing, etc. The laminate 300 is driven to move by the conveyor 400, so that the curing device can be in a production line with the equipment of other processes to achieve flow-type operation.

[0076] In one embodiment, if Figure 2 As shown, the conveyor 400 includes a roller conveyor or a chain conveyor; the height of the conveyor 400 in the receiving tank is lower than the height of the conveyor 400 in the first device 500 or the second device 600, so that the liquid 200 in the receiving tank at least covers the first surface of the laminate 300.

[0077] In one example, a preset track can be set so that the conveying member 400 can be transported in a V-shape, that is, the height of the conveying member 400 in the receiving tank is lower than the height in the two adjacent devices, so that the conveying member 400 can transport the laminate 300 to the receiving tank and make the liquid 200 in the receiving tank submerge the first surface of the laminate 300, and even submerge the second surface of the laminate 300.

[0078] In one embodiment, the carrier 110 includes a first side surface and a second side surface, wherein the first side surface is close to the first device 500 and the second side surface is close to the second device 600. The first side surface is lower than the bearing surface of the first device 500; and the second side surface is lower than the bearing surface of the second device 600.

[0079] The conveyor 400 conveys the laminate 300 from the first device 500 into the receiving tank, and then passes it out of the receiving tank to the second device 600. The conveyor 400 passes through the first side surface and the second side surface, and the heights of the first side surface and the second side surface are adapted to the conveying requirements of the conveyor 400. The bearing surface of the first device 500 is the surface of the first device 500 that bears the conveyor 400; similarly, the bearing surface of the second device 600 is the surface of the second device 600 that bears the conveyor 400. The first side surface is lower than the bearing surface of the first device 500; the second side surface is lower than the bearing surface of the second device 600, so that the conveyor 400 can achieve V-shaped conveyance.

[0080] The first side surface and the second side surface may be two adjacent side surfaces of the carrier 110 , or may be two opposite side surfaces of the carrier 110 .

[0081] Preferably, the first side surface and the second side surface are two oppositely disposed side surfaces of the carrier 110. The conveyor 400 is conveyed in one direction in the receiving groove without turning, thereby preventing the laminate 300 from turning during the curing process, thereby affecting the uniform curing effect of the photovoltaic cell assembly.

[0082] In one embodiment, the accommodating groove is a rectangular groove, and the carrier 110 further includes a third side surface and a fourth side surface opposite to each other, and the heights of the third side surface and the fourth side surface are both higher than the heights of the first side surface and the second side surface.

[0083] The heights of the third side surface and the fourth side surface are both higher than those of the first side surface and the second side surface, so that the effect of converging the light source can be achieved, further improving the curing efficiency.

[0084] In one embodiment, the number of the conveying members 400 includes multiple conveying members 400, and the multiple conveying members 400 are arranged in parallel in the receiving groove; the light source assembly 120 includes multiple light-emitting devices, and the light-emitting devices are used to provide light sources; the multiple light-emitting devices are divided into multiple light-emitting groups, and one conveying member 400 is correspondingly provided with at least one light-emitting group.

[0085] Based on the improvement of the efficiency of light curing, the operation time of light curing is further shortened, and the light curing operation can be completed within 5s to 15s. The number of conveying members 400 can be set according to the operating efficiency of the first device 500 and the operating efficiency of the second device 600; when the first device 500 is a preheating device, multiple laminates 300 can be preheated at one time; when the second device 600 is a cooling and drying device, multiple laminates 300 can be cooled at one time; therefore, by setting multiple conveying members 400, multiple laminates 300 can be accommodated in the receiving tank for curing.

[0086] In one example, the operating efficiency of the first device 500 is 0.5 pieces / s, the operating efficiency of the second device 600 is 0.3 pieces / s, and the operating time of the light curing is 10s; then at least 3 laminates 300 need to be cured simultaneously in the receiving tank to keep up with the operating efficiency of the second device 600, and the number of laminates 300 cured simultaneously may not exceed 5 pieces, so as to avoid the operating efficiency of the first device 500 not keeping up. At this time, 3 conveyors 400 may be provided, and one conveyor 400 conveys one laminate 300 to the receiving tank at a time; or 2 conveyors 400 may be provided, and one conveyor 400 conveys 2 laminates 300 to the receiving tank at a time.

[0087] In order to avoid collision of laminated members 300 conveyed on multiple conveying members 400, a certain interval may be set for the multiple conveying members 400. At the same time, in order to facilitate the light source to irradiate the laminated member 300 without wasting the light source, the multiple light emitting devices in the light source assembly 120 may be divided into multiple light emitting groups; one light emitting group is set corresponding to one conveying member 400, so that the light source emitted by the light emitting group is concentratedly irradiated on the laminated member 300 on the conveying member 400, avoiding the waste of light source.

[0088] In one embodiment, the conveyor 400 includes at least one predetermined position for placing the laminate 300; one predetermined position is set corresponding to one laminate 300; at least one predetermined position is arranged on the conveyor 400 according to a preset first interval, and one predetermined position corresponds to one light-emitting group.

[0089] In one example, the predetermined position on the conveying member 400 is set by setting the position of the light-emitting group in the light source assembly 120 .

[0090] In a more specific example, a conveyor member 400 is provided with two light-emitting groups that irradiate the conveyor member 400; when placing the laminates 300, the first laminate 300 is placed at a position corresponding to the first light-emitting group that can irradiate the conveyor member 400, and the position is the first predetermined position; accordingly, the second laminate 300 is placed at a position corresponding to the second light-emitting group that can irradiate the conveyor member 400.

[0091] In one embodiment, if Figure 3 and Figure 4 As shown, the curing equipment may also include a rotating mechanism, which includes a rotating shaft 114 and at least one supporting platform 115; at least one supporting platform 115 is fixedly connected to the rotating shaft 114 so that the rotating shaft 114 drives at least one supporting platform 115 to rotate; the laminate 300 is placed on the supporting platform 115, and the liquid 200 at least covers the supporting platform 115; the light source emitted by the light source assembly 120 is irradiated to the first position where the supporting platform 115 passes.

[0092] In the embodiment of the present application, a rotating mechanism is provided in the receiving groove so that the rotating shaft 114 can drive the supporting platform 115 to rotate; the supporting platform 115 carries the laminate 300 to be cured, and the supporting platform 115 drives the laminate 300 to rotate in the receiving groove, and can drive the laminate 300 to the first position, so that the light source is irradiated to the laminate 300, thereby promoting the curing of the adhesive film of the laminate 300.

[0093] It can be understood that after the support platform 115 receives the laminate 300, it rotates to the first position after a certain rotation distance, so that the laminate 300 can undergo a local cross-linking reaction based on the liquid 200 of the target temperature in the receiving tank within the rotation distance, and then when it reaches the first position, it is stimulated by light to promote the faster curing of the adhesive film; such a process can shorten the time required for the laminate 300 to be irradiated by the light source during the curing process; and the multiple support platforms 115 in the receiving tank continuously drive other laminates 300 to rotate to the first position, so that when one light source assembly 120 cures multiple laminates 300, the curing efficiency can be improved.

[0094] In the embodiment of the present application, a rotating mechanism is provided in the receiving groove, so that the utilization rate of the light source assembly 120 can be improved, and the curing efficiency of the batch laminated parts 300 can be improved.

[0095] The number of the carriers 115 in the rotating mechanism may be multiple, for example Figure 3 The structure includes four supporting platforms 115, and Figure 4 The structure includes three supporting platforms 115. Figure 4 In the figure, the structure of the rotating shaft 114 is not shown. It can be understood that the rotating shaft 114 can be fixed to the bottom of the receiving groove in the supporting member 110, and can also be suspended above the receiving groove.

[0096] In one embodiment, the conveyor member 400 includes a first conveyor member 410 and a second conveyor member 420, the first conveyor member 410 is used to drive the laminate 300 to be conveyed from the first device 500 toward the receiving tank; the second conveyor member 420 is used to receive the laminate 300 and drive the conveyor member 400 to be conveyed on the second device 600 in a direction away from the receiving tank; the output end of the first conveyor member 410 and the input end of the second conveyor member 420 are close to the carrier 110, and are located above the receiving tank and close to the carrier platform 115.

[0097] The output end of the first conveyor member 410 and the input end of the second conveyor member 420 are close to the carrier 110 and are located above the receiving groove and close to the carrier platform 115, so that the laminate 300 output by the first conveyor member 410 can be transferred to the carrier platform 115; the second conveyor member 420 can receive the cured laminate 300 from the carrier platform 115 and output the cured laminate 300.

[0098] In one example, the shape of the carrier 115 matches the shape of the laminate 300, and the size of the carrier 115 is smaller than the size of the laminate 300, so that when the laminate 300 is placed on the carrier 115, it has a protruding edge, and based on the protruding edge, it achieves contact with the conveyor 400. When the laminate 300 contacts the conveyor 400, the laminate 300 is received or output based on the power and inertia of the conveyor 400.

[0099] In the embodiment of the present application, the conveying member 400 is designed to be close to the carrying platform 115, so as to achieve the handover of the laminated member 300 between the conveying member 400 and the carrying platform 115, thereby facilitating the assembly line preparation of photovoltaic cell components.

[0100] In one embodiment, the curing device further includes: a displacement mechanism, a lifting mechanism 116 and a position detection mechanism.

[0101] The displacement mechanism controls the first conveyor member 410 and / or the second conveyor member 420 to move toward / away from the receiving slot; the displacement mechanism can be arranged near the first device 500 or the second device 600 so that the displacement mechanism can control the first conveyor member 410 / the second conveyor member 420 to move toward or away from the receiving slot.

[0102] By controlling the first conveyor 410 / second conveyor 420 to approach or move away from the receiving groove through the displacement mechanism, when the conveyor 400 and the carrier 115 hand over the laminate 300, the handover can be active, thereby improving the handover efficiency and further improving the curing efficiency.

[0103] The lifting mechanism 116 is disposed in the receiving groove, and the position of the lifting mechanism 116 matches the position of the first conveying member 410 and / or the second conveying member 420; the lifting mechanism 116 includes a driving device and a flat plate 1161 for receiving the laminated member 300. The driving device can determine that the flat plate 1161 realizes lifting and lowering motion. The flat plate 1161 is located at a position where it can be connected with the first conveying member 410 and / or the second conveying member 420.

[0104] The position detection mechanism is used to send a command to the driving device when the first conveying member 410 moves toward the receiving groove and detects that the first conveying member 410 moves to the specified position, so that the driving device controls the lifting mechanism 116 to rise and the flat plate 1161 receives the laminate 300.

[0105] The position of the lifting mechanism 116 is adapted to the position of the first conveyor member 410 and / or the second conveyor member 420; the flat plate 1161 of the lifting mechanism 116 can be set at a position that the first conveyor member 410 and / or the second conveyor member 420 can reach, and is staggered with the first conveyor member 410 and / or the second conveyor member 420, and the staggered interval can be 1 / 5~1 / 10 of the length of the laminate 300, or 1 / 5~1 / 10 of the width of the laminate 300, to avoid the flat plate 1161 hitting the first conveyor member 410 and / or the second conveyor member 420 when rising.

[0106] In one example, if Figure 5 As shown, when the displacement mechanism controls the first conveying member 410 to move toward the direction close to the receiving groove, the flat plate 1161 can be controlled to rise. When the first conveying member 410 is in place, the flat plate 1161 rises to the bottom of the laminate 300 and continues to rise to support the laminate 300; the displacement mechanism controls the first conveying member 410 to move in the direction away from the receiving groove until the first conveying member 410 is away from the platform; the flat plate 1161 drives the laminate 300 to descend until it descends to the supporting platform 115, and the laminate 300 is handed over to the supporting platform 115. The flat plate 1161 continues to descend, so that the supporting platform 115 can rotate, driving the laminate 300 to rotate to the first position to complete the curing.

[0107] In one example, when the displacement mechanism is activated, or when the lifting mechanism 116 is activated, the rotation mechanism can be controlled to stop rotating to prevent the supporting platform 115 from hitting the lifting mechanism 116 .

[0108] In one example, at least two plates 1161 are provided at one handover position to support the laminate 300 from both sides and improve the stability of the handover process. The two plates 1161 can be controlled by a driving device; further, the two plates 1161 can be connected to the same support member 1162.

[0109] In one example, the carrier 115 includes at least two through holes for the at least two plates 1161 to pass through, so that when the plates 1161 move downward, the plates 1161 can pass through the through holes and leave the laminate 300 on the carrier 115 .

[0110] In one embodiment, if Figure 5 and Figure 6 As shown, the lifting mechanism 116 also includes a support member 1162 , and the support member 1162 includes a first end and a second end opposite to each other; the first end is rotatably connected to the bottom of the carrier 110 located in the receiving groove; and the second end is rotatably connected to the plate 1161 .

[0111] The two ends of the support member 1162 are rotatably connected to the flat plate 1161 and the bottom of the receiving groove, so that a Z-shaped structure is formed between the three. The change of the angle in the Z-shaped structure can cause the change of the height of the flat plate 1161, thereby realizing the lifting process of the flat plate 1161. The lifting operation of the flat plate 1161 can be controlled by a driving device, and the driving device can realize the lifting process of the flat plate 1161 by controlling the middle part of the support member 1162 and pushing and pulling the middle part of the support member 1162.
