Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, specifically to a photovoltaic module cleaning device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It is a clean energy source with very promising prospects. During the assembly of photovoltaic modules, the photovoltaic panels need to be placed inside a frame coated with adhesive for bonding and fixing. After the photovoltaic panels are bonded to the frame, excess adhesive may appear at the four corners. To address this issue, the standard practice is to have one person on each side of the photovoltaic module wipe the four corners clean with a lint-free cloth.

[0003] Currently, some methods utilize robots to replace manual labor for wiping operations. For example, CN222261100U discloses a photovoltaic module corner wiping device, including a conveyor line, two sets of dividing systems, and two sets of robotic arms for wiping CCDs. The conveyor line is placed horizontally, with a set of robotic arms for wiping CCDs and a dividing system placed in front of and behind the conveyor line, respectively. A photovoltaic module steering system is fixed inside the conveyor line at positions corresponding to the two sets of robotic arms wiping CCDs. While this disclosed technology reduces manual labor by using robotic arms, the design of the CCD wiping system on the robot is complex and costly. Utility Model Content

[0032] This embodiment provides a photovoltaic module cleaning device, referring to... Figure 1-6 As shown, the system includes a feeding mechanism 100 for supplying non-woven fabric for wiping and cleaning, a side wiping mechanism 200 for wiping the edges and sides of the photovoltaic panel, a guide 300 for changing the orientation of the inner and outer surfaces of the non-woven fabric, a bottom wiping mechanism 400 for wiping the bottom of the edges or corners of the photovoltaic panel, and a mounting frame 700 for mounting the feeding mechanism 100, the side wiping mechanism 200, the guide 300, and the bottom wiping mechanism 400. The mounting frame 700 mainly consists of a first support plate 710, a second support plate 720, and support columns 730. The second support plate 720 and the first support plate 710 are sequentially and spaced apart from bottom to top on four support columns 730, with the first support plate 710 and the second support plate 720 below it arranged parallel vertically. In this embodiment, both the first support plate 710 and the second support plate 720 are rectangular structural plates. In some preferred embodiments, the mounting frame 700 is further provided with a lifting drive unit 740. In this case, the first support plate 710 and the support column 730 are slidably disposed, and the main body of the lifting drive unit 740 is connected to the middle slotted structure of the second support plate 720, with the end of its drive shaft connected to the lower surface of the first support plate 710. The height of the first support plate 710 can be adjusted by the lifting drive unit 740, thereby adjusting the height of the corresponding structure connected to the first support plate 710.

[0033] The feeding mechanism 100 mainly consists of a support base 110 and a tray 120 rotatably connected to the support base 110. The support base 110 is fastened to the outer right angle of the first support plate 710, and the tray 120 is rotatably connected to the support column of the support base 110. The tray 120 has a receiving groove in the middle for installing and placing a non-woven fabric roll for wiping and cleaning, and the tray 120 also has an opening for the end of the non-woven fabric to extend out. When the non-woven fabric is pulled out, the non-woven fabric roll can rotate within the tray 120 to continuously supply non-woven fabric.

[0034] The side wiping mechanism 200 includes a side wiping drum 210, a side drum drive motor for driving the side wiping drum 210 to rotate, and a first pressing assembly 220 for bringing the non-woven fabric into contact with the surface of the side wiping drum 210 and rotating it with it. The side wiping drum 210 is rotatably connected to the upper surface of a first mounting plate 711 extending outward from one side of the first support plate 710. The drum 210 and the tray 120 are located on opposite sides of the length of the first support plate 710. The body of the side drum drive motor is fastened to the lower surface of the first mounting plate 711 and located below the side wiping drum 210. The drive shaft of the side drum drive motor extends to the first mounting plate 711, forms a through hole, and drives the side wiping drum 210. The side wiping drum 210 rotates in a horizontal plane under the drive of the side drum drive motor. Rotation in a horizontal plane means that its rotating surface is substantially parallel to the surface of the first support plate 710. The first pressing assembly 220 mainly includes a first pressure roller 221 and a second pressure roller 222. Both the first pressure roller 221 and the second pressure roller 222 are short cylindrical structures, located on the sides of the side wiping drum 210. Preferably, to increase the length of the non-woven fabric attached to the surface of the side wiping drum 210 and improve the wiping cleaning effect, the first pressure roller 221 and the second pressure roller 222 are arranged adjacent to each other on the sides of the side wiping drum 210. The first pressure roller 221 and the second pressure roller 222 can be connected to the first mounting plate 711 by a fixed and rotating manner. Preferably, the first pressing assembly 220 also includes a first telescopic unit 223, which includes a first telescopic motor 2231 for driving and a first sliding frame 2232. The first pressure roller 221 and the second pressure roller 222 are rotatably connected to one end of the first sliding frame 2232. The other end of the first sliding frame 2232 is driven by the first telescopic motor 2231, which is connected to the upper surface of the first support plate 710. The first telescopic motor 2231 drives the first sliding frame 2232 to move the first pressure roller 221 and the second pressure roller 222 closer to or further away from the side to wipe the surface of the rotating drum 210.

[0035] The guide member 300 is a plate structure with a guide groove 310 in its middle. The guide groove 310 is rectangular in shape, and its edges are smoothed to reduce damage to the non-woven fabric passing through it. The guide member 300 is suspended and connected to the lower surface of the second support plate 720 on one side, with the guide groove 310 located on the outside of the second support plate 720. The guide member 300 connected to the second support plate 720 and the side wiping rotary cylinder 210 are located on the same side of the mounting frame 700 along its length.

[0036] The bottom wiping mechanism 400 mainly includes a bottom wiping drum 410, a bottom drum drive motor for rotating the bottom wiping drum 410, and a second pressing assembly 420 that brings the non-woven fabric into contact with the surface of the bottom wiping drum 410 and causes it to rotate with the drum. The bottom wiping drum 410 is rotatably connected to the outside of the first mounting plate 711 via a support structure, and the bottom drum drive motor drives the bottom wiping drum 410 to rotate. The central axis of the connected bottom wiping drum 410 is perpendicular to the central axis of the side wiping drum 210, and the rotating surface of the bottom wiping drum 410 is a vertical surface, which means that the rotating surface of the bottom wiping drum 410 is basically perpendicular to the plane of the first support plate 710. The second pressing assembly 420 mainly includes a third pressure roller 421 and a fourth pressure roller 422. Both the third pressure roller 421 and the fourth pressure roller 422 are short cylindrical structures, located below the bottom wiping drum 410. Similarly, to increase the length of the non-woven fabric attached to the surface of the bottom wiping drum 410 and improve the wiping cleaning effect, the third pressure roller 421 and the fourth pressure roller 422 located below the bottom wiping drum 410 are arranged adjacent to each other. The third pressure roller 421 and the fourth pressure roller 422 can be connected to the first mounting plate 711 by a fixed and rotating method, for example, by a support rod supporting and connecting the third pressure roller 421 and the fourth pressure roller 422. Preferably, the second pressing assembly 420 also includes a second telescopic unit 423, which includes a second telescopic motor 4231 for driving and a second sliding frame 4232. The third pressure roller 421 and the fourth pressure roller 422 are rotatably connected to one end of the second sliding frame 4232. The other end of the second sliding frame 4232 is driven by the second telescopic motor 4231. The second sliding frame 4232 and the second telescopic motor 4231 are fixedly connected to the second mounting plate 712, which is a structural plate connected to the side of the first support plate 710. The second telescopic motor 4231 drives the second sliding frame 4232 to move the third pressure roller 421 and the fourth pressure roller 422 closer to or further away from the bottom surface to wipe the surface of the rotating drum 410.

[0037] The working principle of the photovoltaic module cleaning device provided by this utility model is as follows: (Refer to...) Figure 1-2As shown, a non-woven fabric roll for cleaning is rotatably connected to the receiving cavity of the tray 120, with the end of the rolled non-woven fabric leading out from a notch in the tray 120. The end of the non-woven fabric pulled from the tray 120 enters from the side of the first pressure roller 221 and wraps around the circumference of the side wiping drum 210, and then its end is led out from the side of the second pressure roller 222. The end of the non-woven fabric led out from the side of the second pressure roller 222 is pulled downward to the position of the guide member 300. The end of the non-woven fabric passes through the guide groove 310 from bottom to top through the edge outside the guide groove 310 and is pulled upward. At this time, the inner surface of the non-woven fabric in contact with the circumference of the side wiping drum 210 is flipped to become the outer surface, while the outer surface in contact with and wiping the edge of the photovoltaic panel to be cleaned is flipped to become the inner surface. After being pulled upwards to a certain height, the non-woven fabric end enters through the third pressure roller 422 and wraps around the circumference of the bottom wiping drum 410. At this time, the outer surface that was in contact with and wiped the edge of the photovoltaic panel to be cleaned is flipped into the inner surface and comes into contact with the circumference of the bottom wiping drum 410. Meanwhile, the uncontaminated inner surface that was in contact with the circumference of the side wiping drum 210 is flipped into the outer surface and comes into contact with the bottom edge of the photovoltaic panel for wiping and cleaning. The wiping and cleaning of the sides and bottom of the photovoltaic panel's corners is performed simultaneously. The mounting bracket 710 can be slidably set on a slide rail or other structure to move back and forth and left and right, thereby realizing the wiping operation of the sides and bottom of the photovoltaic panel's corners.

[0038] This invention achieves simultaneous cleaning of both sides and the bottom by offsetting the side wiping drum and setting the drum bodies at a 90° angle. Furthermore, it uses a guide to flip the wiping surfaces of the non-woven fabric used for wiping the sides and the bottom. This not only improves cleaning efficiency but also ensures cleaning quality by using both sides of the same non-woven fabric. Moreover, it makes efficient use of the consumable non-woven fabric, reducing the cost of consumables by 50%. This energy-saving and consumption-reducing function has yielded significant economic benefits. Example

[0039] This embodiment 2 is based on embodiment 1. By optimizing the drive mechanism of the side wiping drum and the bottom wiping drum into an integrated structure, the synchronization of the nonwoven fabric rotation on the two drums is improved, while the overall structure of the device is more compact and the cost of the device is effectively reduced. Specifically:

[0040] Refer to Figure 1 and 4As shown, a rotary drum drive mechanism 500 is provided to simultaneously drive the synchronous rotation of the side wiping rotary drum 210 and the bottom wiping rotary drum 410. The rotary drive mechanism 500 mainly includes a rotary drive motor 510, a main drive shaft 520, and a driven shaft 530, and also includes a housing 540 for mounting. The housing 540 includes a vertical housing 541 and a horizontal housing 542, both of which are rectangular structures. The vertical housing 541 is suspended and connected to the lower surface of the first mounting plate 711, and the rotary drive motor 510 is disposed inside the vertical housing 541. The horizontal housing 541 lies horizontally on the upper surface of the first mounting plate 711, the main drive shaft 520 is arranged perpendicular to the first mounting plate 711, and the driven shaft 530 is arranged parallel to the first mounting plate 711. The lower end of the main drive shaft 520 is rotatably connected to the rotary drive motor 510, and its upper end is rotatably connected to the drum shaft of the side wiping rotary drum 210, which is located on the upper surface of the horizontal housing 542. In this embodiment, the driven shaft 530 is a T-shape formed by two drive shafts. One shaft of the driven shaft 530 is rotatably connected to the middle of the main drive shaft 520 via two meshing bevel gears. The bottom wiping drum 410 is rotatably connected to the shaft head of the driven shaft 530 and is located on the side of the transverse housing 542. A single drum drive motor 510 can simultaneously drive the side wiping drum 210 and the bottom wiping drum 410 via the main drive shaft 520 and the driven shaft 530. Example

[0041] This embodiment 3 is based on embodiment 1 or 2. By adding a blowing component, high-pressure airflow is used to blow away contaminants such as colloids adhering to the edges of the photovoltaic panel before wiping and cleaning, effectively improving the cleaning quality. Specifically:

One end is used to connect with external high-pressure gas, and the other end is provided with an air hole 621. Through the air hole 621, the external high-pressure gas forms an airflow and blows it towards the edges of the photovoltaic panel to be cleaned. Preferably, the purging assembly 600 is further provided with a collection box 630, which is connected to the upright plate of the bracket 610 and located below the air hole 621, for collecting the colloids and other contaminants that are blown away. Example

[0043] This embodiment 4 is formed based on any one of embodiments 1-3. By sliding the mounting bracket 700 onto the slide 800, a unit module for cleaning photovoltaic modules is formed. Specifically:

[0044] Reference Figure 5-6 As shown, the carriage 800 mainly includes a slide rail 810 and a displacement drive motor 820.
