In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0052] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Embodiment 1

[0054] The existing automatic component cleaning machine uses a roller to clean the overflowed glue. The silicone will stick to the roller, which increases the process of manually cleaning the roller. Moreover, the roller cannot be cleaned in time, which will cause secondary pollution to the components. Therefore, the existing cleaning machine does not achieve the effect of saving labor and improving cleaning efficiency.

[0055] Based on this, the present application provides a photovoltaic module frame cleaning device, referring to Figure 1 , the device comprises a frame 1, a cleaning platform 2 mounted on the frame 1, and at least one dry ice cleaning mechanism 3;

[0056] The cleaning platform 2 is used to carry the photovoltaic assembly 100;

[0057] Each dry ice cleaning mechanism 3 includes a dry ice storage container, a nozzle 31 and a pipe connected between the dry ice storage container and the nozzle 31 ; the nozzle 31 is used to spray dry ice toward the photovoltaic assembly 100 on the cleaning platform 2 .

[0058] When it is necessary to clean the overflowed glue on the frame of the photovoltaic module 100, first, place the photovoltaic module 100 on the cleaning platform 2 and align the nozzle 31 with the overflowed glue position; then, turn on the dry ice cleaning mechanism 3, and the nozzle 31 sprays dry ice toward the photovoltaic module 100 on the cleaning platform 2. When the dry ice particles come into contact with the surface of the silica gel, the dry ice quickly evaporates into CO2 gas due to the temperature difference, and the generated gas quickly impacts and explodes the silica gel, causing it to peel off from the surface of the photovoltaic module frame.

[0059] The cleaning device provided by the present application has at least the following advantages:

[0060] 1. Effectively remove the overflow glue on the frame of photovoltaic modules, ensuring the cleanliness of photovoltaic modules and preventing secondary pollution of modules;

[0061] 2. The cycle of replacing auxiliary materials (i.e. replenishing dry ice in the dry ice storage container) is extended, which truly achieves the effect of saving labor and improving cleaning efficiency;

[0062] 3. Dry ice cleaning uses solid carbon dioxide (dry ice) as a medium. It directly converts dry ice particles into CO2 gas for cleaning through high-speed jetting. It does not require the use of water or chemical solvents, fundamentally reduces the consumption of water resources, avoids the pollution of the environment by harmful chemicals, and meets the requirements of sustainable development.

[0063] 4. A non-contact cleaning method is used, which does not require direct contact with the frame of the photovoltaic module, thereby avoiding scratching or damaging the photovoltaic module 100.

[0064] In this embodiment, a nozzle fixing plate 11 is provided on the frame 1, and a mounting through hole is provided on the nozzle fixing plate 11, and the nozzle 31 passes through the mounting through hole; a fastener is screwed on the hole wall of the mounting through hole, and the end of the fastener abuts against the nozzle 31. Optionally, the fastener can be a set screw. The above structure can adjust the distance between the nozzle 31 and the photovoltaic module 100 so that the nozzle 31 is in the optimal cleaning position. When the position of the nozzle 31 needs to be adjusted, the fastener can be loosened to move the nozzle 31 along the axial direction of the mounting through hole, thereby changing the distance between the nozzle 31 and the photovoltaic module 100.

[0065] Continue to refer to Figure 1 Each dry ice cleaning mechanism 3 further includes a visual detection structure 32, which is used to collect images of the photovoltaic components 100 on the cleaning platform 2 and transmit the images to the image analysis system.

[0066] In this embodiment, the visual inspection structure 32 is specifically a camera; the camera can capture an image of the photovoltaic module 100 on the cleaning platform 2 and transmit the image to the image analysis system, and the image analysis system can identify and analyze the image to detect whether there is glue overflow on the photovoltaic module 100. The photovoltaic module 100 is inspected by the visual inspection structure 32 before and after the photovoltaic module 100 is cleaned to determine whether the photovoltaic module 100 needs to be cleaned and whether it is cleaned. The visual inspection structure 32 can automatically identify the cleaning effect, ensure that the glue overflow can be completely cleaned, and improve the final quality of the photovoltaic module 100.

[0067] On the basis of the above structure, each dry ice cleaning mechanism 3 also includes a protective box (not shown in the figure) installed on the frame 1, and the camera is arranged in the protective box. The box opening of the protective box faces the cleaning platform 2 and has a box door that can be opened and closed automatically at the box opening, or the camera can be moved out of or into the protective box through a driving structure. When the camera is needed to take pictures, the box door is opened or the camera is moved out of the protective box, so that the camera can take pictures of the photovoltaic module 100; when the dry ice cleaning mechanism 3 is working or stopped, the box door is closed or the camera is moved into the protective box. The structure of the protective box is relatively common and will not be described in detail here.

[0068] Reference Figure 2 and Figure 3 , the photovoltaic module frame cleaning device also includes a first conveying mechanism 4 and a second conveying mechanism 5, and the first conveying mechanism 4 is installed on the cleaning platform 2;

[0069] The photovoltaic assembly 100 can be transferred and transported between the first transport mechanism 4 and the second transport mechanism 5 .

[0070] Specifically, the first conveying mechanism 4 and the second conveying mechanism 5 are both belt conveying mechanisms, and the belt conveying mechanism is an existing structure and is not described in detail here. The second conveying mechanism 5 is used to convey the external photovoltaic components 100 to the first conveying mechanism 4, so that the photovoltaic components 100 are automatically conveyed to the cleaning platform 2 for the cleaning process; the first conveying mechanism 4 is used to re-convey the photovoltaic components 100 that have been cleaned to the second conveying mechanism 5 to wait for the next cleaning process. The cleaning device provided in the present application does not require manual placement of the photovoltaic components 100, further reducing the amount of manual labor and improving the degree of automation of the production line.

[0071] Optionally, the number of the second conveying mechanism 5 may be one, and the input and output of the photovoltaic assembly 100 can be achieved by changing the conveying directions of the first conveying mechanism 4 and the second conveying mechanism 5. Figure 4 The number of the second conveying mechanisms 5 can also be two, and they are respectively arranged at the opposite ends of the first conveying mechanism 4 along the conveying direction, wherein one second conveying mechanism 5 is used to input the photovoltaic component 100, and the other second conveying mechanism 5 is used to output the photovoltaic component 100 to realize streamlined cleaning work.

[0072] Continue to refer to Figure 2 and Figure 3 , the cleaning platform 2 has a conveying state and a cleaning state, wherein:

[0073] When the cleaning platform 2 is in the cleaning state, the photovoltaic assembly 100 on the cleaning platform 2 and the jet port of the nozzle 31 are at the same horizontal plane;

[0074] When the cleaning platform 2 is in the conveying state, the conveying surface of the first conveying mechanism 4 and the conveying surface of the second conveying mechanism 5 are at the same horizontal plane;

[0075] The photovoltaic module frame cleaning device further comprises a lifting mechanism 6 for driving the cleaning platform 2 to switch between a cleaning state and a conveying state.

[0076] Reference Figure 2 When the cleaning platform 2 is in the cleaning state, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 on the cleaning platform 2 to lift up, so that the photovoltaic component 100 on the cleaning platform 2 and the injection port of the nozzle 31 are at the same horizontal plane; at this time, the nozzle 31 can aim at the overflow position of the photovoltaic component 100 and spray dry ice to achieve the cleaning of the overflow glue of the photovoltaic component frame.

[0077] Reference Figure 3 When the cleaning platform 2 is in the conveying state, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 on the cleaning platform 2 to descend, so that the conveying surface of the first conveying mechanism 4 and the conveying surface of the second conveying mechanism 5 are on the same horizontal plane; at this time, the photovoltaic component 100 can be transferred and transported between the first conveying mechanism 4 and the second conveying mechanism 5.

[0078] Specifically, the lifting mechanism 6 includes a lifting drive 62, which can be a gas cylinder or an oil cylinder. The cylinder body of the lifting drive 62 is installed on the frame 1, and the piston rod of the lifting drive 62 is connected to the cleaning platform 2, thereby driving the cleaning platform 2 to rise and fall.

[0079] Reference Figure 4 The photovoltaic module frame cleaning device also includes a correction mechanism installed on the cleaning platform 2, and the correction mechanism includes multiple sets of correction wheel assemblies 81; the multiple sets of correction wheel assemblies 81 are distributed around the photovoltaic module 100 on the cleaning platform 2, and can jointly clamp or release the photovoltaic module 100 on the cleaning platform 2 to correct the photovoltaic module 100. The correction mechanism is an existing structure and is not described in detail here.

[0080] Continue to refer to Figure 4 In the process of spraying dry ice from the nozzle 31, the angle between the axis of the nozzle 31 and the side wall of the photovoltaic module 100 is in the range of 15° to 60°. For example, the angle between the axis of the nozzle 31 and the frame of the photovoltaic module 100 can be 15°, 30°, 45°, or 60°. Preferably, the angle between the axis of the nozzle 31 and the frame of the photovoltaic module 100 is 45°. At this angle, the gas after the dry ice evaporates can more easily peel the silica gel from the surface of the photovoltaic module frame.

[0081] In this embodiment, each dry ice cleaning mechanism 3 includes two nozzles 31, and the two nozzles 31 correspond to two adjacent edges of the photovoltaic module 100 respectively. Figure 4 As shown, the two nozzles 31 correspond to the adjacent long sides and short sides of the photovoltaic module 100 respectively, so that the overflowed glue on the adjacent long sides and short sides can be cleared at the same time.

[0082] On the basis of the above structure, the two nozzles 31 in the dry ice cleaning mechanism 3 are symmetrically arranged, and the symmetry line is the angle bisector of the angle formed by the corresponding two sides. Under the impact of the dry ice sprayed from the two nozzles 31, the overflow glue at the corners of the frame can be peeled off more thoroughly. Furthermore, during the operation of the visual detection structure 32, the camera is arranged on the symmetry line of the two nozzles 31, and it can be aimed at the corners of the frame to take pictures.

[0083] Continue to refer to Figure 4In this embodiment, the number of dry ice cleaning mechanisms 3 is two, and the two dry ice cleaning mechanisms 3 correspond to any two corners of the photovoltaic assembly 100 on the cleaning platform 2. In this embodiment, the two dry ice cleaning mechanisms 3 correspond to two corners at both ends of a short side of the photovoltaic assembly 100.

[0084] Furthermore, the photovoltaic module frame cleaning device also includes a rotating mechanism 7, which is used to drive the cleaning platform 2 to rotate. Figure 4 and Figure 5 ,when Figure 3 After the two corners on the left side of the photovoltaic assembly 100 are cleaned, the rotating mechanism 7 drives the cleaning platform 2 to rotate 180°, so that the two corners on the right side of the photovoltaic assembly 100 are respectively aligned with the two dry ice cleaning mechanisms 3 and cleaned, and all four corners of the photovoltaic assembly 100 are cleaned.

[0085] Refer to 2 and Figure 6 , the rotating mechanism 7 comprises:

[0086] The rotating frame 71 is rotatably mounted on the frame 1; the cleaning platform 2 is connected to the rotating frame 71;

[0087] The rotary driving member 72 is installed on the frame 1 , and its output end is connected to the rotary frame 71 .

[0088] Specifically, the rotating mechanism 7 also includes a rotating shaft 73 and a belt 74, wherein: the rotating drive member 72 can be a motor, which is mounted on the frame 1; the rotating shaft 73 is rotatably mounted on the frame 1 through a bearing, and its upper end is connected to the rotating frame 71 through a flange, and its lower end is connected to the output shaft of the rotating drive member 72 through a gear and a belt 74.

[0089] Reference Figure 6 In this embodiment, the lifting mechanism 6 includes a connecting plate 61 fixed on the lower end surface of the cleaning platform 2, the piston rod of the lifting drive member 62 is connected to the connecting plate 61, and the cylinder of the lifting drive member 62 is installed on the rotating frame 71; a plurality of guide shafts 63 are arranged on the connecting plate 61, and a plurality of linear bearings 64 are installed on the rotating frame 71. The guide shafts 63 and the linear bearings 64 correspond to each other one by one, and the guide shafts 63 are slidably inserted in the corresponding linear bearings 64. The guide shafts 63 and the linear bearings 64 play a guiding role in the lifting process of the cleaning platform 2, and the stability of the lifting device during the working process.

[0090] On the basis of the above structure, when the piston rod of the lifting drive member 62 is retracted, the connecting plate 61 abuts against the upper end surface of the rotating frame 71, so that the first conveying mechanism 4 is more stable during the conveying process.

[0091] The cleaning process of the cleaning device provided in the first embodiment is as follows:

[0092] Reference Figure 3 In the initial state, the cleaning platform 2 is in a conveying state, and the second conveying mechanism 5 conveys the photovoltaic assembly 100 to be cleaned to the first conveying mechanism 4 (that is, the cleaning platform 2), and the photovoltaic assembly 100 is clamped together by multiple sets of alignment wheel assemblies 81 to position the photovoltaic assembly 100 on the cleaning platform 2;

[0093] Reference Figure 2 Then, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 to rise, and the camera takes images of the two corners of the frame, analyzes the images and identifies whether there is glue overflow; after determining that there is glue overflow, align the nozzle 31 with the glue overflow position, turn on the dry ice cleaning mechanism 3, and the nozzle 31 sprays dry ice toward the photovoltaic module 100 on the cleaning platform 2 to peel off the glue overflow at the two corners of the photovoltaic module frame; after the cleaning is completed, the camera takes images of the cleaning area, analyzes the images and identifies the cleaning effect;

[0094] After confirming that the overflow glue is completely cleaned, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 to descend, and the rotating mechanism 7 drives the cleaning platform 2 and the first conveying mechanism 4 to rotate 180°. Then, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 to rise, and the other two corners are identified and analyzed and the overflow glue is cleaned; after the cleaning is completed, the camera takes an image of the cleaning area, analyzes the image and identifies the cleaning effect;

[0095] After all cleaning is completed, the lifting mechanism 6 drives the cleaning platform 2 and the first conveying mechanism 4 to descend, and the multiple sets of return wheel assemblies 81 release the photovoltaic components 100. The first conveying mechanism 4 conveys the photovoltaic components 100 that have been cleaned to the second conveying mechanism 5, and the second conveying mechanism 5 conveys the photovoltaic components 100 that have been cleaned to the next process.
