Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic module production technology, and in particular relates to a machine for cleaning excess glue at the four corners of photovoltaic module frames. [Background Technology]

[0002] The fabrication of photovoltaic (PV) modules generally consists of a cover plate, solar cells, tempered glass, encapsulating adhesive, a backsheet, and an aluminum alloy frame. These components are laminated to form a complete PV module. During the lamination process, the cover plate and backsheet are subjected to pressure, causing the encapsulating adhesive to overflow from the four corners of the PV module. This adhesive residue affects the quality of the PV module. The traditional method is to remove the adhesive manually. This manual operation is time-consuming and labor-intensive, and it also leaves marks on the glass, affecting the quality of the finished PV module.

[0003] Existing technologies include automatic cleaning devices. For example, the photovoltaic module frame-mounted corner adhesive cleaning device disclosed in Chinese Patent Publication No. CN220970078U has four cleaning mechanisms at the four corners of the photovoltaic module. Each cleaning mechanism includes cleaning modules A, B, C, and D, which can clean the right side of the corner, the middle gap side, the left side of the corner, and the inner side of the bottom surface of the corner of the photovoltaic module. This can automatically complete the adhesive cleaning of the four corners of the photovoltaic module. However, this solution still has the following problems:

[0004] (1) The cleaning mechanism is driven by a rear servo motor to lift and move. Although a protective cover is provided, cleaning fluid will inevitably splash onto the servo motor, which will cause the servo motor to short circuit. This will not only affect the entire cleaning process, but also increase maintenance costs.

[0005] (2) The residual adhesive removed during cleaning will enter the water supply tank along with the cleaning solution. The residual adhesive in the water supply tank will contaminate the cleaning solution. Then, this contaminated cleaning solution will be used to clean the residual adhesive on the new photovoltaic modules. Not only will the cleaning effect be worse, but it may also cause secondary contamination of the photovoltaic modules, affecting the quality of the photovoltaic modules.

[0006] (3) The plan only describes the high-pressure gas source, but does not disclose the function of the high-pressure gas source or the specific structure involved in performing this function.

[0007] Therefore, it is necessary to provide a machine for cleaning excess adhesive at the four corners of photovoltaic module frames to solve the above-mentioned technical problems. [Utility Model Content]

[0008] The main purpose of this utility model is to provide a cleaning machine for the four corners of photovoltaic modules after they are assembled into frames. This machine solves the problem of the servo motor short circuit affecting the entire cleaning process, and also solves the problem of secondary contamination of photovoltaic modules by glue in the circulating cleaning solution. Furthermore, it can be adapted to photovoltaic modules of different sizes, thus improving the versatility of the cleaning machine.

[0012] Furthermore, the first cylinder is mounted on the lifting plate, and a first slide rail is provided on the upper surface of the lifting plate. The positioning platform is slidably mounted on the first slide rail via a first slider.

[0013] The positioning platform has a first positioning part and a second positioning part that are perpendicular to each other on the side near the lifting plate.

[0014] Furthermore, the adhesive removal mechanism includes a third cylinder mounted on the positioning platform, a first mounting frame driven by the third cylinder to move in the X direction, a fourth cylinder mounted on the positioning platform, and a second mounting frame driven by the fourth cylinder to move in the Y direction. Both the first mounting frame and the second mounting frame are provided with a first nozzle for cleaning the side of the photovoltaic module and a second nozzle for cleaning the lower surface of the photovoltaic module.

[0015] Furthermore, the adhesive removal device is adjustablely mounted on the frame via a first movable module. The first movable module includes a second slide rail mounted on the frame along the Y direction and a third slide rail mounted on the second slide rail and extending along the X direction via a second slider. The first mounting plate is adjustablely mounted on the third slide rail via a third slider.

[0016] Furthermore, the lifting plate is equipped with a first air blowing component that blows air onto the lower surface of the photovoltaic module.

[0017] Furthermore, the air blowing module includes a second mounting plate disposed on the frame, a fifth cylinder disposed on the lower surface of the second mounting plate, a third mounting frame driven by the fifth cylinder to move in the X direction, a sixth cylinder disposed on the lower surface of the second mounting plate, and a fourth mounting frame driven by the sixth cylinder to move in the Y direction. A second air blowing component is disposed on the third mounting frame, and a third air blowing component is disposed on the fourth mounting frame.

Detailed Implementation Methods

[0039] Please refer to Figures 1-7 This embodiment is a photovoltaic module frame rear corner overflow cleaning machine 100. The photovoltaic module frame rear corner overflow cleaning machine 100 includes a frame 1, a module conveyor line 2, a blocking and straightening mechanism 3 for blocking and straightening the photovoltaic module, four cleaning devices 4 respectively set at the four corners of the photovoltaic module, a liquid storage device 7 for providing cleaning fluid to the cleaning devices 4 and receiving the returned cleaning fluid, and a hot air blower 5 set at the front end of the module conveyor line 2 to dry the lower surface of the photovoltaic module. Each cleaning device 4 is provided with a blowing module 6 on its side to dry the two right-angle adjacent sides of the photovoltaic module. The four cleaning devices 4 simultaneously clean the overflow of the photovoltaic module at the four corners. The cleaning device 4 includes a lifting mechanism 41 set on the frame 1, a first cylinder 42 set on the lifting mechanism 41, a positioning platform 43 driven by the first cylinder 42 to move away from or abut against the two right-angle sides of the photovoltaic module, and a cleaning mechanism 44 set on the positioning platform 43 to clean the right-angle adjacent sides and bottom surface of the photovoltaic module.

[0040] The module conveyor line 2 is a motor-driven belt conveyor with three parallel belts to ensure the stability of the photovoltaic module conveying. The obstruction and correction mechanism 3 includes an obstruction component 31 that obstructs the front end of the photovoltaic module conveying, a first correction component 32 that corrects the left and right sides of the photovoltaic module, and a second correction component 33 that corrects the rear end of the photovoltaic module conveying. The structures of the obstruction component 31, the first correction component 32, and the second correction component 33 are conventional designs in the prior art and will not be described in detail here.

[0041] The lifting mechanism 41 includes a first mounting plate 411 mounted on the frame 1, a second cylinder 412 mounted on the first mounting plate 411, a lifting plate 413 driven by the second cylinder 412 to move up and down, several guide rods 414 movably mounted at one end of the lifting plate 413, a lifting plate 415 fixedly mounted on the top of the guide rods 414, and springs 416 sleeved on the outer periphery of the guide rods 414. The upper end of the spring 416 abuts against the lower surface of the lifting plate 415, and the lower end abuts against the upper surface of the lifting plate 413. The springs 416 enable the lifting plate 415 to elastically support the lower surface of the photovoltaic module. When the photovoltaic module is partially warped, the elastic support can better contact and support the lower surface of the photovoltaic module, ensuring stability when lifting the photovoltaic module and preventing the photovoltaic module from shifting during lifting.

[0042] The first cylinder 42 is mounted on the lifting plate 413. The upper surface of the lifting plate 413 is provided with a first slide rail 4131. The positioning table 43 is slidably mounted on the first slide rail 4131 via the first slider 431. Several guide rods 414 are mounted on one end of the lifting plate 413, and the first slide rail 4131 is mounted on the other end of the lifting plate 413. The two do not interfere with each other.

[0043] The positioning platform 43 is provided with a first positioning part 432 and a second positioning part 433 that are perpendicular to each other on the side near the lifting plate 415. When the first cylinder 42 drives the positioning platform 43 to move to the right angle side of the photovoltaic module, the first positioning part 432 and the second positioning part 433 respectively abut against the right angle of the photovoltaic module to achieve positioning of the two sides of the right angle of the photovoltaic module.

[0044] The adhesive cleaning mechanism 44 includes a third cylinder 441 mounted on a positioning platform 43, a first mounting frame 442 driven by the third cylinder 441 to move along the X direction, a fourth cylinder 443 mounted on the positioning platform 43, and a second mounting frame 444 driven by the fourth cylinder 443 to move along the Y direction. Both the first mounting frame 442 and the second mounting frame 444 are equipped with a first nozzle 445 for cleaning the side of the photovoltaic module and a second nozzle 446 for cleaning the bottom surface of the photovoltaic module. The first nozzle 445 is located above the positioning platform 43, and the second nozzle 446 is located between the positioning platform 43 and the lifting plate 415. The angles of the first nozzle 445 and the second nozzle 446 are adjustable. The first nozzle 445 and the second nozzle 446 on the first mounting frame 442 clean the side and bottom surface of the right angle side, respectively, and the first nozzle 445 and the second nozzle 446 on the second mounting frame 444 clean the side and bottom surface of the other right angle side, respectively.

[0045] The position of the adhesive removal device 4 is adjustable. The adhesive removal device 4 is adjustablely mounted on the frame 1 via the first movable module 45. The first movable module 45 includes a second slide rail 451 mounted on the frame 1 along the Y direction and a third slide rail 453 mounted on the second slide rail 451 and extending along the X direction via the second slider 452. The first mounting plate 411 is adjustablely mounted on the third slide rail 453 via the third slider 454. The second slider 452 can move along the Y direction on the second slide rail 451, and the third slider 454 can move along the X direction on the third slide rail 453. After the first slider 451 and the third slider 454 are positioned, they are locked with screws. If the position of the adhesive removal device 4 needs to be adjusted, the screws can be loosened, and the position of the adhesive removal device 4 in the X and Y directions can be adjusted by adjusting the position of the first slider 451 and the third slider 454. This allows it to be adapted to photovoltaic modules of different sizes, improving the versatility of the cleaning machine. The cleaning device 4 in the activity can be set by a slider rail. With the help of a servo motor, the cleaning device 4 can be automatically adjusted in position. So when changing photovoltaic modules of different types, the position of the cleaning device 4 can be switched by one key in the control system, which can improve the versatility of the cleaning machine.

[0046] After the excess adhesive is cleaned, to prevent the cleaning fluid from dripping onto the machine, a first air blowing component 46 is installed on the lifting plate 413 to blow air onto the lower surface of the photovoltaic module. The first air blowing component 46 blows air to remove the cleaning fluid from the bottom surface of the photovoltaic module. Two sets of hot air blowers 5 are installed at a height lower than the module conveyor line 2. Heated high-pressure airflow is introduced into the hot air blowers 5, and the two sets of hot air blow hot air onto the lower sides of the photovoltaic module to dry the bottom surface of the photovoltaic module.

[0047] The air blowing module 6 includes a second mounting plate 61 mounted on the frame 1, a fifth cylinder 62 mounted on the lower surface of the second mounting plate 61, a third mounting frame 63 driven by the fifth cylinder 62 to move in the X direction, a sixth cylinder 64 mounted on the lower surface of the second mounting plate 61, and a fourth mounting frame 65 driven by the sixth cylinder 62 to move in the Y direction. A second air blowing assembly 66 is mounted on the third mounting frame 63, and a third air blowing assembly 67 is mounted on the fourth mounting frame 65. The second air blowing assembly 66 and the third air blowing assembly 67 respectively blow air to dry the right-angled sides of the photovoltaic module.

[0048] The first air blowing assembly 46, the second air blowing assembly 66, and the third air blowing assembly 67 all include an air blowing nozzle and an air blowing hose connected to the air blowing nozzle. The position and angle of the air outlet of the air blowing hose are adjustable, so as to be able to adapt to photovoltaic modules of different sizes.

[0049] The first air blowing component 46, the second air blowing component 66, and the third air blowing component 67 all introduce high-pressure airflow to blow away the cleaning liquid at the cleaning location of the photovoltaic module, thus preventing the cleaning liquid from remaining on the photovoltaic module and affecting its quality.

[0050] The liquid storage device 7 includes a receiving tank 71 located below the adhesive removal device 4, a storage tank 72 connected to the receiving tank 71, and a water pump 73 that pumps the cleaning liquid in the storage tank 72 into the adhesive removal device 4. The water pump 73 is connected to the first nozzle 445 and the second nozzle 446, and pumps the cleaning liquid in the storage tank 72 into the first nozzle 445 and the second nozzle 446 to clean the excess adhesive at the four corners of the photovoltaic module. Each adhesive removal device 4 has a receiving tank 71 below it. Therefore, there are a total of four receiving tanks 71. The cleaning liquid that flows back after cleaning flows into the receiving tank 71. The back cleaning liquid in the front and rear receiving tanks 71 flows into the storage tank 72. Therefore, the front and rear receiving tanks 71 share one storage tank 72. Thus, there are two storage tanks 72 on the left and right sides. The bottom of the liquid storage tank 72 is equipped with casters to facilitate moving the liquid storage tank 72 when changing the cleaning fluid; the liquid level display structure on the liquid storage tank 72 can directly and conveniently read the liquid level of the liquid storage tank 72, so as to facilitate timely addition of cleaning fluid to the liquid storage tank 72.

[0051] Since the cleaning solution is recycled, the returned cleaning solution contains the glue that was washed off. In order to avoid secondary contamination of the photovoltaic modules by the glue, both the receiving tank 71 and the storage tank 72 are equipped with a filter structure to filter out the glue in the returned cleaning solution, thus ensuring the cleaning quality of the photovoltaic modules.

[0052] When using the photovoltaic module frame rear corner overflow cleaning machine 100 provided in this solution, when the module conveyor line 2 delivers the photovoltaic module to its position, the blocking component 31 blocks the front end of the photovoltaic module. The first straightening component 32 straightens the left and right sides of the photovoltaic module, and the second straightening component 33 straightens the rear end of the photovoltaic module. After straightening the four sides of the photovoltaic module, the first straightening component 32 and the second straightening component 33 reset. Then, the lifting mechanism 41 lifts the photovoltaic module from the module conveyor line 2. Specifically, the second cylinder 412 drives the lifting plate 413 to rise, lifting the photovoltaic module, and the lifting plate 415 elastically supports the lower surface of the photovoltaic module. The four lifting mechanisms 41 simultaneously elastically support the four corners of the photovoltaic module. The first cylinder 42 drives the positioning platform 43 to approach the right angle of the photovoltaic module. The first positioning part 432 and the second positioning part 433 respectively abut against the right angle of the photovoltaic module, realizing the cleaning of the two sides of the right angle of the photovoltaic module. Positioning: Four positioning platforms 43 simultaneously position the four right angles of the photovoltaic module. After positioning, high-pressure water flow is activated, and the adhesive removal mechanism 44 begins to clean the excess adhesive from the photovoltaic module. The first nozzle 445 and the second nozzle 446 on the first mounting frame 442 clean the side and bottom of one side of the right angle, respectively. The first nozzle 445 and the second nozzle 446 on the second mounting frame 444 clean the side and bottom of the other side of the right angle, respectively. The four adhesive removal mechanisms 44 simultaneously complete the cleaning of excess adhesive from the four right angles of the photovoltaic module. After cleaning, the first air blowing component 46 blows air to remove the cleaning liquid from the bottom surface of the photovoltaic module. At the same time, the second air blowing component 66 and the third air blowing component 67 blow air to dry the two sides of the right angle of the photovoltaic module, respectively. The blocking component 31 is reset, and the cleaned photovoltaic module flows out. Two sets of hot air blow hot air to the bottom of the photovoltaic module on both sides to dry the bottom surface of the photovoltaic module, completing the cleaning action of excess adhesive from the four corners of the photovoltaic module.

[0053] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
