Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic component sunlight board coating device. Background Art

[0002] Glass, the front covering of photovoltaic modules, protects the cells. It's typically made of tempered glass and is relatively heavy. Currently, some photovoltaic modules use solar panels to protect the cells, replacing glass. These panels can be made of lightweight, highly transparent materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA), significantly reducing weight while maintaining excellent flexibility. Pigments or dyes can also be added to solar panels to create color effects. These colored panels offer a wide range of color options for photovoltaic modules, allowing them to blend seamlessly with architectural exteriors.

[0003] Solar panels generally require an anti-yellowing agent. Applying an anti-yellowing agent to the surface of the panels effectively prevents yellowing and maintains long-term light transmittance, thus preventing the impact of reduced light transmittance on the power generation efficiency of photovoltaic modules. During coating, all areas to be coated must be coated uniformly to ensure the desired effect. Failure to adhere to these two requirements can easily affect the progress of yellowing on the panels' surface, especially when coating panels in batches. Utility Model Content

[0045] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figures 1 to 5 As shown, the utility model provides a photovoltaic module sun panel coating device, comprising:

[0048] Liquid storage component 1, used for storing anti-yellowing agent;

[0049] Fixing component 2, used for fixing the solar panel 3;

[0050] And the driving component 4 is connected to the fixing component 2, and is used to drive the fixing component 2 to move horizontally or vertically in different time periods; the driving component 4 can drive the fixing component 2 to make the sun panel 3 enter the inner side of the liquid storage component 1 to contact the anti-yellowing agent.

[0051] During actual operation, an anti-yellowing agent is placed in the liquid storage component 1. After the fixing component 2 fixes the sun panel 3, the driving component 4 first drives the fixing component 2 in the horizontal direction so that the sun panel 3 enters the area directly above the liquid storage component 1, and then the driving component 4 drives the fixing component 2 in the vertical direction so that the sun panel 3 enters the inner side of the liquid storage component 1 to contact the anti-yellowing agent.

[0052] The process of fixing the solar panel 3 by the fixing assembly 2 can be manually intervened, and the solar panel 3 is fixed by manually operating the fixing assembly 2 .

[0053] By dipping the sun panel 3 into the anti-yellowing agent in a dipping manner, on the one hand, the area to be coated of the sun panel 3 can be quickly coated and the actual coating area can be guaranteed to be no less than the expected coating area; on the other hand, the area to be coated of the sun panel 3 can be uniformly coated to ensure the coating effect; on the other hand, batch coating of multiple sun panels 3 can be completed within the same time period to further speed up the coating progress.

[0054] The anti-yellowing agent can be selected according to actual conditions, such as a light stabilizer such as a hindered amine light stabilizer.

[0055] When the driving assembly 4 is in use, a supporting structure such as a supporting rod can be provided to support it according to actual conditions.

[0056] It should be noted that solar panels can be made of lightweight and highly transparent materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA), which greatly reduce weight while having good flexibility. Pigments or dyes can also be added to solar panels to achieve color effects. This colored solar panel provides a rich color selection for photovoltaic modules, allowing them to better blend with the exterior of the building. By replacing photovoltaic glass with colored solar panels, lightweight, flexible and colorful photovoltaic modules can be made.

[0057] Example 2

[0058] In this embodiment, the liquid storage component 1 includes a liquid storage portion 11, which has a liquid storage cavity 111 with an upward opening, and the liquid storage cavity 111 is used to store the anti-yellowing agent; the driving component 4 can drive the fixing component 2 to move along the length direction of the liquid storage cavity 111, and the driving component 4 can also drive the fixing component 2 to move in the vertical direction so that the sun panel 3 enters the liquid storage cavity 111.

[0059] In the liquid storage assembly 1 , the liquid storage operation is completed by the liquid storage portion 11 , specifically, the liquid storage cavity 111 .

[0060] The liquid storage portion 11 can store the anti-yellowing agent, providing convenience for the dip coating of the solar panel 3 .

[0061] The size of the liquid storage chamber 111 can be adjusted according to the conditions of the solar panel 3 .

[0062] Example 3

[0063] In this embodiment, the liquid storage assembly 1 further includes a covering portion 12 , which is slidably connected to the liquid storage portion 11 and is used to cover the opening of the liquid storage cavity 111 . The covering portion 12 can move along the width direction of the liquid storage cavity 111 .

[0064] The covering portion 12 can move along the width direction of the liquid storage chamber 111. During the non-processing stage, the covering portion 12 moves to the top of the opening of the liquid storage chamber 111 to cover the opening of the liquid storage chamber 111, thereby preventing the anti-yellowing agent from being contaminated. During this process, the covering portion 12 cooperates with the liquid storage portion 11 to complete the liquid storage operation; during the processing stage, the covering portion 12 moves to the side of the opening of the liquid storage chamber 111 to avoid affecting the entry of the sun panel 3 into the liquid storage chamber 111.

[0065] The covering portion 12 can be set as a plate-like structure and its size can be adjusted according to the size of the opening of the liquid storage chamber 111; the covering portion 12 can be set on the top of the liquid storage portion 11; the covering portion 12 and the liquid storage portion 11 can be slidably connected through a slide groove; the covering portion 12 and the liquid storage portion 11 can be set separately to facilitate cleaning of both.

[0066] Example 4

[0067] In this embodiment, the fixing assembly 2 includes a supporting portion 21 and a plurality of fixing portions 22 spaced apart along the length direction of the liquid storage chamber 111 . The supporting portion 21 is connected to the driving assembly 4 . The fixing portions 22 are all installed at the bottom of the supporting portion 21 and are used to fix the solar panel 3 .

[0068] The actual fixing structure in the fixing assembly 2 is the fixing portion 22 . In some cases, the operator fixes the solar panel 3 in mid-air through the fixing portion 22 and supports it with the supporting portion 21 , which is in turn supported by the driving assembly 4 .

[0069] The provision of multiple fixing portions 22 enables the fixing assembly 2 to fix multiple solar panels 3 at the same time, facilitating batch coating of the solar panels 3 .

[0070] Example 5

[0071] In this embodiment, the fixing portion 22 includes a plurality of fixing sub-portions 221 spaced apart along the width direction of the liquid storage chamber 111 . The fixing sub-portions 221 are installed at the bottom of the supporting portion 21 and are used to fix the solar panel 3 .

[0072] The fixing sub-portion 221 may be configured as a clip, such as a C-shaped clip, or may be configured as other fixing devices, which are not specifically limited herein.

[0073] The fixing portion 22 is composed of two fixing sub-portions 221 , and the two fixing sub-portions 221 are spaced apart along the width direction of the liquid storage chamber 111 . The two fixing sub-portions 221 can respectively clamp the two ends of the sun panel 3 to achieve stable clamping of the sun panel 3 .

[0074] Example 6

[0075] In this embodiment, the driving assembly 4 includes a driving part 41, a driving member 42 installed on the driving part 41, and the support part 21 is connected to the driving member 42; the driving part 41 can drive the driving member 42 to move along the length direction of the liquid storage chamber 111; the driving member 42 can drive the support part 21 to move along the vertical direction.

[0076] The driving part 41 can be set as a single-axis robot or other devices that can drive the driving member 42 to move along the length direction of the liquid storage chamber 111; the driving member 42 can be set as a combination structure of a winch and a traction line or other devices that can drive the support part 21 to move in the vertical direction, and no specific limitation is made here.

[0077] The driving portion 41 and the driving member 42 can drive the solar panel 3 to move in different directions, so as to achieve the purpose of moving the solar panel 3 closer to the liquid storage chamber 111 and farther away from the liquid storage chamber 111 .

[0078] Example 7

[0079] In this embodiment, along the length direction of the liquid storage cavity 111 , a receiving portion 5 is detachably connected to one side of the liquid storage portion 11 , and the receiving portion 5 is used to receive the anti-yellowing agent separated from the solar panel 3 .

[0080] After the driving component 4 drives the fixing component 2 in the vertical direction so that the sun panel 3 enters the inner side of the liquid storage component 1 to contact the anti-yellowing agent, the driving part 42 drives the sun panel 3 to reset in the vertical direction, and then the driving part 41 drives the sun panel 3 to continue to move in the horizontal direction to the area directly above the receiving part 5.

[0081] After the anti-yellowing agent is coated on the surface of the polycarbonate sheet 3, it needs to be dried to solidify the anti-yellowing agent on the surface of the polycarbonate sheet 3. The solidification process ensures that the anti-yellowing agent is firmly bonded to the surface of the polycarbonate sheet 3 and forms a durable protective layer.

[0082] During the drying process, part of the anti-yellowing agent is separated from the polycarbonate sheet 3 under the action of gravity. The receiving portion 5 can be used to collect this part of the anti-yellowing agent to avoid waste.

[0083] In some cases, the liquid storage portion 11 and the receiving portion 5 are rotatably connected.

[0084] The liquid storage portion 11 and the receiving portion 5 can be separated to facilitate replacement of the receiving portion 5 with different sizes.

[0085] The specific connection method in the present invention can be adjusted according to actual conditions. For example, the detachable connection method can be achieved by threaded connection, which is not specifically limited here.

[0086] Example 8

[0087] In this embodiment, the receiving portion 5 is inclined; the liquid storage portion 11 is provided with a liquid inlet 112 connected to the liquid storage cavity 111, and the receiving portion 5 can guide the anti-yellowing agent separated from the sun panel 3 to flow back into the liquid storage cavity 111 through the liquid inlet 112.

[0088] The inclined arrangement of the receiving portion 5 and the arrangement of the liquid inlet 112 enable the receiving portion 5 to guide the anti-yellowing agent separated from the solar panel 3 to flow back into the liquid storage chamber 111 through the liquid inlet 112, thereby omitting the step of manually processing this part of the anti-yellowing agent.

[0089] When the anti-yellowing agent is not required to flow back into the liquid storage chamber 111 through the liquid inlet 112 within a short period of time, the liquid inlet 112 can be blocked by a blocking structure such as a blocking plate. This setting can also be made when in the non-processing stage.

[0090] Regarding the inclined setting of the receiving part 5, in some cases, the receiving part 5 is rotatably connected to the liquid storage part 11 and can be separated. A supporting structure such as a support rod can be set at the bottom of the receiving part 5. Support structures of different lengths can make the inclination angle of the receiving part 5 different.

[0091] Example 9

[0092] In this embodiment, along the length direction of the liquid storage chamber 111, the side of the receiving part 5 away from the liquid storage part 11 is detachably connected to the heating component 6, and the heating component 6 includes a heating part 61 and an air supply part 62. The heating part 61 is detachably connected to the receiving part 5, and the air supply part 62 is installed on the heating part 61 and is used to transport hot air to the inside of the heating part 61; one end of the driving part 41 is installed on the inside of the heating part 61.

[0093] The driving part 41 may be supported by a separate supporting structure or by the heating part 61 .

[0094] The heating portion 61 may be supported by the receiving portion 5 , or the heating portion 61 may be arranged to be in contact with the ground and supported by the ground when in use.

[0095] The air delivery unit 62 can be configured as a hot air blower or other device, and is not specifically limited here. The air delivery unit 62 can be installed inside or outside the heating unit 61. When the air delivery unit 62 is installed outside the heating unit 61, the heating unit 61 is provided with holes for the air delivery unit 62 to deliver hot air.

[0096] Some anti-yellowing agents need to be heated to accelerate their curing process and improve the curing effect; some anti-yellowing agents can be cured at room temperature. At this time, if heating is performed, it may also accelerate the curing process or produce other effects, such as helping the anti-yellowing agent to penetrate more evenly into the surface of the polycarbonate sheet 3 to form a denser cured film layer.

[0097] When the anti-yellowing agent stops dripping or the dripping amount is small, the driving unit 41 drives the sun panel 3 to move into the heating unit 61. The hot air is transported by the air delivery unit 62, and the sun panel 3 can be dried at a temperature higher than the room temperature, thereby achieving the effect of accelerating the curing of the anti-yellowing agent.

[0098] Through the hot air conveying of the air delivery part 62, the temperature inside the heating part 61 is significantly higher than the temperature outside the heating part 61, which can simultaneously accelerate the drying progress of each solar panel 3 and avoid mutual influence due to the solar panels 3 being placed side by side.

[0099] Example 10

[0100] In this embodiment, the heating portion 61 has a heating chamber 611 opening toward the liquid storage portion 11. Two sealing portions 7 are symmetrically distributed along the width direction of the liquid storage chamber 111 at the opening of the heating chamber 611. The sealing portions 7 are all rotatably connected to the heating portion 61, and the sealing portions 7 are used to block the opening of the heating chamber 611; the end of any sealing portion 7 close to another sealing portion 7 is elastic; and a reset portion 8 is connected between each sealing portion 7 and the heating portion 61.

[0101] The blocking portion 7 is rotatably connected to the heating portion 61 , and the blocking portion 7 can rotate around an axis extending in the vertical direction.

[0102] The air delivery portion 62 delivers hot air into the heating chamber 611 . The heating chamber 611 opens toward the liquid storage portion 11 , making it easier for the solar panel 3 to enter the heating chamber 611 .

[0103] The sealing portion 7 is used to seal the opening of the heating chamber 611 before and after the solar panel 3 enters the heating chamber 611 to maintain the temperature within the heating chamber 611. When the solar panel 3 enters the heating chamber 611, the support portion 21 and other structures push the sealing portion 7 to rotate. After the solar panel 3 enters the heating chamber 611, the return portion 8 facilitates the return of the sealing portion 7.

[0104] The reset portion 8 can be configured as an elastic structure, such as a spring, a torsion spring, etc.

[0105] The end of any blocking part 7 close to another blocking part 7 is elastic. This part can be made of elastic materials such as rubber or can be set as an elastic pad, sponge pad, etc., so as to adapt to the shape of the driving part 41 and avoid interference between the blocking parts 7 during movement.

[0106] It should be noted that the various driving structures and output structures in the present invention, such as the driving part 41 and the air delivery part 62, can be controlled by existing controllers and other control devices, and are not specifically limited here.
