[0047] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0048] The following description will refer to the drawings to more comprehensively describe the content of the present application. The exemplary embodiments shown in the drawings are of the present application. However, the present application can be implemented in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided to make the present application thorough and complete, and to fully convey the scope of the present application to those skilled in the art. Similar reference numerals denote the same or similar components.

[0049] Refer to Figure 1, this application proposes a production device 100, which includes an upper silicone plate 110, a lower silicone plate 120, a processing device 130, and a controller 140. The lower silicone plate 120 is used to cooperate with the upper silicone plate 110 to form a first sealed cavity. The processing device 130 is used to form a second sealed cavity. The controller 140 is electrically connected to the processing device 130. The controller 140 is used to control the second sealed cavity to be heated to a preset temperature; and adjust the air pressure in the first sealed cavity to a first air pressure value, and adjust the air pressure in the second sealed cavity to a second air pressure value; the difference between the second air pressure value and the first air pressure value is within a first difference range; adjust the air pressure in the second sealed cavity to a third air pressure value; the third air pressure value is greater than the first air pressure value, and the difference between the third air pressure value and the first air pressure value is within a second difference range; adjust the air pressure in the second sealed cavity to a fourth air pressure value; the fourth air pressure value is greater than the third air pressure value. Adjust the air pressure in the second sealed cavity to a fifth air pressure value and maintain it for a fourth preset duration; the fifth air pressure value is greater than the fourth air pressure value.

[0050] In this embodiment, the production device 100 can perform encapsulation processing on the curved solar panel 200. The number of curved solar panels 200 can be multiple. The curved solar panel 200 includes a front curved panel, an encapsulation film, a power generation panel, and a back panel. As Figures 2 to 8 shown, the front curved panel, the encapsulation film, the power generation panel, the encapsulation film, and the back panel are laid sequentially from bottom to top to obtain the solar panel to be encapsulated. The upper silicone plate 110 has convex grooves, and the lower silicone plate 120 has concave grooves. Place the solar panel to be encapsulated on the lower silicone plate 120, cover the upper silicone plate 110, so that the convex grooves of the upper silicone plate 110 fit with the concave grooves of the lower silicone plate 120 to form a first sealed cavity, and then put it into the processing device 130, close the door of the processing device 130, and form a second sealed cavity in the processing device 130. Among them, the back panel can be a straight flexible back panel, which can deform with the power generation panel during processing; or, the back panel can be a rigid back panel with the same shape as the front curved panel, and apply pressure to the power generation panel to deform it together with the front curved panel during processing.

[0051] After that, the controller 140 controls the second sealed cavity to be heated to a preset temperature. The first sealed cavity in the second cavity will also gradually heat up to the preset temperature due to heat conduction, so that the encapsulation film in the first sealed cavity can melt at high temperature. At the same time, the controller 140 adjusts the air pressure in the first sealed cavity to the first air pressure value, and adjusts the air pressure in the second sealed cavity to the second air pressure value. After adjusting the air pressure in the first sealed cavity to the first air pressure value and adjusting the air pressure in the second sealed cavity to the second air pressure value, the first preset time can be maintained to achieve the first-stage lamination of the solar panel to be encapsulated.

[0052] Furthermore, it can be understood that during the process of heating the second sealed cavity to the preset temperature, the heating rate in the first sealed cavity is less than that in the second sealed cavity. At this time, the temperature in the first sealed cavity has not reached the preset temperature, and the yield strength of the material piece of the solar panel to be encapsulated is relatively large, and it is easily damaged when subjected to pressure. Therefore, during the heating process of the second sealed cavity, the air pressure values in the first sealed cavity and the second sealed cavity can be slowly adjusted simultaneously to make the pressures of the two consistent, or the air pressure value in the second sealed cavity is slightly less than that in the first sealed cavity. In this way, the upper silicone plate 110 and the lower silicone plate 120 will not deform or deform outward, thereby avoiding damaging the product by applying pressure to the solar panel to be encapsulated.

[0053] Among them, the first difference range can be set according to actual needs. For example, the first difference range can be set to 50 kPa, the first air pressure value can be set to -100 kPa, and the second air pressure value can be any value between -100 kPa or -150 kPa to -100 kPa. In this way, not only can the air pressure value in the second sealed cavity be equal to or slightly less than that in the first sealed cavity, but also the upper silicone plate 110 and the lower silicone plate 120 can be prevented from falling off.

[0054] After the heating is completed, the encapsulation adhesive film melts at high temperature. At this time, the air pressure value and temperature in the first sealed cavity remain unchanged, and the controller 140 controls the air pressure value in the second sealed cavity to be adjusted to a third air pressure value greater than the first air pressure value to generate a pressure difference between the second sealed cavity and the first sealed cavity, thereby applying pressure to the solar panel material piece in the first sealed cavity. After adjusting the air pressure in the second sealed cavity to the third air pressure value, the second preset time can be maintained to achieve the second-stage lamination of the solar panel to be encapsulated. Then, the controller 140 controls the air pressure value in the second sealed cavity to be adjusted to a fourth air pressure value greater than the third air pressure value. Bubbles will be generated when the encapsulation adhesive film melts. By continuously increasing the air pressure value in the second sealed cavity and increasing the pressure of the second sealed cavity on the first sealed cavity, the solar panel to be encapsulated is pressurized again, and the bubbles that are not easily removed inside can be extruded. After adjusting the air pressure in the second sealed cavity to the fourth air pressure value, the third preset time can be maintained to achieve the third-stage lamination of the solar panel to be encapsulated.

[0055] Next, the controller 140 can control the air pressure value in the second sealed cavity to continue to increase and adjust it to a fifth air pressure value greater than the fourth air pressure value. The pressure of the second sealed cavity on the first sealed cavity is continuously increased, and the pressure of the upper silicone plate 110 and the lower silicone plate 120 on the solar panel to be encapsulated is increased, so that each material layer can be closely attached together and shaped under high temperature and high pressure. After adjusting the air pressure in the second sealed cavity to the fifth air pressure value, the fourth preset time can be maintained to implement the fourth-stage lamination of the solar panel to be encapsulated, forming a Figure 9 curved solar panel as shown.

[0056] Among them, the third air pressure value, the fourth air pressure value, and the fifth air pressure value can be set according to actual needs, so that the pressure of the second sealed cavity on the first sealed cavity gradually increases. For example, the second difference range between the third air pressure value and the first air pressure value can be set to 20 kPa, the third difference range between the fourth air pressure value and the first air pressure value can be set to 40 kPa, and the fourth difference range between the fifth air pressure value and the first air pressure value can be set to 80 kPa. In addition, the third air pressure value, the fourth air pressure value, and the fifth air pressure value can also be set to other values according to actual needs, which is not limited here.

[0057] In one embodiment, the production equipment 100 further includes a heating device 150. The controller 140 is used to control the heating device 150 to heat the second sealed cavity to a preset temperature. Among them, the heating device 150 can be realized by using an electric heating wire.

[0058] In one embodiment, the production equipment 100 further includes an air pump 160. The controller 140 is used to control the air pump 160 to adjust the air pressure values of the first sealed cavity and the second sealed cavity. The number of air pumps 160 can be set to multiple according to the number of products and the number of processing devices 130. Multiple air pumps 160 can be connected to the processing device 130 or the silicone plate through air pipes.

[0059] The controller 140 can control the air pump 160 to evacuate the first sealed cavity to make it in a vacuum state for subsequent processing of the solar panel to be encapsulated. The controller 140 can also control the air pump 160 to evacuate or inflate the second sealed cavity to adjust the air pressure value of the second sealed cavity, and then adjust the pressure of the second sealed cavity on the first sealed cavity, that is, adjust the pressure on the solar panel to be encapsulated, so as to gradually strengthen the shaping of the solar panel to be encapsulated and avoid product fragmentation caused by constant-pressure processing of the solar panel to be encapsulated.

[0060] In this application, two sealed cavities are provided, and the first sealed cavity is arranged inside the second sealed cavity. By keeping the air pressure value in the first sealed cavity unchanged and adjusting the air pressure value in the second sealed cavity, the pressure difference between the two sealed cavities is adjusted. Furthermore, the pressure exerted on the solar panel to be encapsulated during processing can be controlled by the upper silicone plate 110 and the lower silicone plate 120, enabling the pressure exerted on the solar panel during processing to gradually increase, achieving gradual enhanced shaping of the product, and solving the problem of product fragmentation under constant pressure processing.

[0061] Referring to Figure 10 , this application also proposes a method for manufacturing a curved solar panel 200, which is applied to the above production equipment 100. The production equipment 100 includes a first sealed cavity and a second sealed cavity. The first sealed cavity is arranged inside the second sealed cavity. The curved solar panel 200 is placed inside the first sealed cavity. The method for manufacturing the curved solar panel 200 includes:

[0062] S1: Heat the second sealed cavity to a preset temperature;

[0063] In this embodiment, after heating the second sealed cavity to the preset temperature, the first sealed cavity inside the second cavity will also gradually heat up to the preset temperature due to heat conduction, enabling the encapsulation adhesive film inside the first sealed cavity to melt at a high temperature.

[0064] S2: Adjust the air pressure inside the first sealed cavity to a first air pressure value and adjust the air pressure inside the second sealed cavity to a second air pressure value, and maintain for a first preset duration; the difference between the second air pressure value and the first air pressure value is within a first difference range.

[0065] In this embodiment, air bubbles will be generated when the encapsulation adhesive film melts. By adjusting the air pressure value inside the first sealed cavity to be lower than the atmospheric pressure value, such as -100 kPa, to make it in a vacuum state, the air bubbles inside the solar panel to be encapsulated can be extracted, and oxidation of the power generation panel in the solar panel can be avoided.

[0066] In some embodiments, step S2 and step S1 can also be carried out simultaneously. During the process of heating the second sealed cavity to a preset temperature, the heating rate in the first sealed cavity is less than that in the second sealed cavity. At this time, the temperature in the first sealed cavity has not reached the preset temperature, and the yield strength of the material piece of the solar panel to be encapsulated is relatively large, and it is easily damaged when subjected to pressure. Therefore, during the heating process of the second sealed cavity, the air pressure values in the first sealed cavity and the second sealed cavity can be slowly adjusted simultaneously to make the pressures of the two consistent, or the air pressure value in the second sealed cavity is slightly less than that in the first sealed cavity. In this way, the upper silicone plate 110 and the lower silicone plate 120 will not deform or deform outwards, thereby avoiding damaging the product by applying pressure to the solar panel to be encapsulated. Among them, the preset temperature can be set according to the melting point of the encapsulation film, for example, set to 140°C to 150°C, so that the encapsulation film can be completely melted. In addition, the preset temperature can also be set higher or lower according to actual needs, and no limitation is made here. The first difference range can be set according to actual needs. For example, the first difference range can be set to 50 kPa, the first air pressure value can be set to -100 kPa, and the second air pressure value can be -100 kPa or any value between -150 kPa and -100 kPa. In this way, not only can the air pressure value in the second sealed cavity be equal to or slightly less than that in the first sealed cavity, but also the upper silicone plate 110 and the lower silicone plate 120 can be prevented from falling off. In addition, when processing curved solar panels 200 with different curvatures, the first difference range can be set larger or smaller, such as 20 kPa, 100 kPa, 200 kPa, etc., and no limitation is made here.

[0067] It can be understood that the faster the air pressure decreases, the faster the heating rate in the first sealed cavity and the faster the thermal deformation rate of the encapsulation film, which may cause uneven melting of the encapsulation film. Therefore, by setting an appropriate first preset duration, the air pressure value in the first sealed cavity can be slowly decreased, that is, the temperature in the first sealed cavity can be slowly increased, ensuring that the encapsulation film can be uniformly heated and melted. For example, when the preset temperature is 140°C to 150°C, the first preset duration can be set to 260 s to 1200 s. In addition, the first preset duration can also be set to other values according to actual needs, and no limitation is made here.

[0068] Referring to Figure 11 , in one embodiment, adjusting the air pressure in the first sealed cavity to the first air pressure value and adjusting the air pressure in the second sealed cavity to the second air pressure value includes:

[0069] S21: Evacuate the first sealed cavity at the first air flow rate for a fifth preset duration to adjust the air pressure in the first sealed cavity to a first air pressure, and evacuate the second sealed cavity at a second air flow rate for a sixth preset duration to adjust the air pressure in the second sealed cavity to a second air pressure; the difference between the first air flow rate and the second air flow rate is within a second difference range.

[0070] In this embodiment, by simultaneously evacuating the first sealed cavity and the second sealed cavity at the first air flow rate and the second air flow rate for the same duration, the pressure difference between the first sealed cavity and the second sealed cavity is always kept consistent, so that the force on the solar panel to be encapsulated is always consistent. Among them, the fifth preset duration and the sixth preset duration can be set according to the time required to heat to the preset temperature to slowly reduce the air pressure values in the first sealed cavity and the second sealed cavity.

[0071] S3: Adjust the air pressure in the first sealed cavity to a third air pressure value and maintain it for a second preset duration; the third air pressure value is greater than the first air pressure value, and the difference between the third air pressure value and the first air pressure value is within the second difference range.

[0072] In this embodiment, after heating is completed, the encapsulation adhesive film melts at a high temperature. At this time, keep the air pressure value and temperature in the first sealed cavity unchanged, and adjust the air pressure value in the second sealed cavity to a third air pressure value greater than the first air pressure value to generate a pressure difference between the second sealed cavity and the first sealed cavity, so as to apply pressure to the solar panel material in the first sealed cavity. Among them, the second preset duration can be set according to actual needs. For example, it can be set to 30s - 600s to slowly increase the pressure on the solar panel so that the melted encapsulation film can be evenly dispersed.

[0073] In one embodiment, adjusting the air pressure in the first sealed cavity to the third air pressure value includes:

[0074] S31: Inflate the second sealed cavity at a third air flow rate for a seventh preset duration to adjust the air pressure in the second sealed cavity to the third air pressure.

[0075] In this embodiment, by inflating the second sealed cavity to increase the pressure, a pressure difference is generated between the second sealed cavity and the first sealed cavity, and then pressure is applied to the solar panel to be encapsulated through the upper silica gel plate 110 and the lower silica gel plate 120 for shaping. The seventh preset duration can be set according to the actual inflation situation, and the embodiments of the present application do not limit this.

[0076] S4: Adjust the air pressure in the first sealed cavity to a fourth air pressure value and maintain it for a third preset duration; the fourth air pressure value is greater than the third air pressure value.

[0077] In this embodiment, air bubbles are generated when the encapsulation film melts. By continuously increasing the air pressure value in the second sealed cavity to increase the pressure of the second sealed cavity on the first sealed cavity, the solar panel to be encapsulated is pressurized again, and the air bubbles that are not easily removed inside can be extruded. Among them, the third preset duration can be set according to actual needs. For example, it can be set to 30s to 600s.

[0078] In one embodiment, adjusting the air pressure in the first sealed cavity to a fourth air pressure value includes:

[0079] S41: Inflate the second sealed cavity at a fourth air flow rate for an eighth preset duration so that the air pressure in the second sealed cavity is adjusted to the fourth air pressure; the fourth air flow rate is greater than the third air flow rate.

[0080] In this embodiment, the eighth preset duration can be set according to actual needs to slowly increase the pressure on the solar panel, so that the encapsulation film can be evenly dispersed and the air bubbles can be discharged.

[0081] S5: Adjust the air pressure in the first sealed cavity to a fifth air pressure value and maintain it for a fourth preset duration; the fifth air pressure value is greater than the fourth air pressure value.

[0082] In this embodiment, by continuously increasing the air pressure value in the second sealed cavity, the pressure of the second sealed cavity on the first sealed cavity is further increased, and the pressure of the upper silica gel plate 110 and the lower silica gel plate 120 on the solar panel to be encapsulated is increased, so that each material layer can be closely attached together and shaped under high temperature and high pressure. Among them, the fourth preset duration can be set according to actual needs. For example, it can be set to 1200s to 5400s.

[0083] In one embodiment, adjusting the air pressure in the first sealed cavity to a fifth air pressure value includes:

[0084] S51: Inflate the second sealed cavity at a fifth air flow rate for a ninth preset duration so that the air pressure in the second sealed cavity is adjusted to the fifth air pressure; the fifth air flow rate is greater than the fourth air flow rate.

[0085] In this embodiment, the ninth preset duration can be set according to actual needs, and this application embodiment does not limit it, so that the solar panel can be closely attached under high temperature and high pressure for a sufficient long time to complete shaping and obtain a packaged solar panel. Improve the stability of the product. In this way, by gradually increasing the air pressure value of the second sealed cavity, the upper silica gel plate 110 and the lower silica gel plate 120 gradually strengthen the shaping of the solar panel to be encapsulated, avoiding damage to the product by constant pressure shaping.

[0086] Among them, the third air pressure value, the fourth air pressure value, and the fifth air pressure value can be set according to actual needs, so that the pressure of the second sealed cavity on the first sealed cavity gradually increases. For example, the second difference range between the third air pressure value and the first air pressure value can be set to 20 kPa, the third difference range between the fourth air pressure value and the first air pressure value can be set to 40 kPa, and the fourth difference range between the fifth air pressure value and the first air pressure value can be set to 80 kPa. In addition, the third air pressure value, the fourth air pressure value, and the fifth air pressure value can also be set to other values according to actual needs, which are not limited herein.

[0087] In this application, by keeping the air pressure value in the first sealed cavity unchanged and adjusting the air pressure value in the second sealed cavity at different stages to adjust the pressure difference between the two sealed cavities, the pressure exerted on the solar panel to be encapsulated during processing can be controlled by the upper silica gel plate 110 and the lower silica gel plate 120, so that the pressure exerted on the solar panel during processing gradually increases, realizing the gradual strengthening and shaping of the product, and solving the problem of product fragmentation under constant pressure processing.
