Technical Field

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

[0002] In the production process of photovoltaic modules, it is usually necessary to label the photovoltaic modules by affixing barcodes or printing QR codes to trace the information of the photovoltaic modules, and then the quality of the photovoltaic modules in the production process can be understood through system query. However, the labeling of photovoltaic modules is often done by manual barcode labeling, machine barcode labeling and carbon cloth printing, which reduces the production efficiency of photovoltaic modules. Utility Model Content

[0003] The present application provides a spraying device and a photovoltaic module, which are used to solve the problem of low production efficiency of photovoltaic modules caused by manual barcode sticking, machine barcode sticking and carbon cloth printing.

[0004] In a first aspect, the present application provides a spraying device for spraying a photovoltaic module, the spraying device comprising a base, a spraying assembly and a cleaning assembly, the spraying assembly being mounted on the base, the spraying assembly comprising an ink cartridge and a nozzle connected to the ink cartridge, the ink cartridge being used to store ink, the nozzle being used to spray ink, the cleaning assembly comprising a cleaning body, the cleaning body being used to clean the nozzle.

[0005] In this solution, after receiving the signal, the spraying device controls the ink in the ink cartridge to spray out through the nozzle to form a barcode on the photovoltaic module. Compared with the methods of manually attaching barcodes, machine attaching barcodes and carbon cloth printing, this spraying method can improve the spraying efficiency, thereby improving the production efficiency of photovoltaic modules. At the same time, after the spraying component sprays the barcode on the photovoltaic module, the spraying component and the cleaning component move close to each other, so that the cleaning body can clean the residual ink and external dust on the nozzle, improve the cleanliness of the nozzle, and prevent the ink remaining on the nozzle from affecting the next spraying of the barcode by the spraying component, which is beneficial to improving the clarity of the barcode, and further beneficial to improving the reliability and convenience of the spraying component, thereby improving the efficiency of the spraying equipment for spraying photovoltaic modules and further improving the efficiency of photovoltaic module production.

[0006] In this solution, the material of the cleaning body is sponge.

[0007] In this solution, since the sponge is absorbent, the ink can be absorbed into the cleaning body during the process of the cleaning body wiping the residual ink at the nozzle, which is beneficial to improving the cleaning ability of the cleaning body to clean the ink and can reduce the risk of ink dripping during the wiping process.

[0008] In this solution, the cleaning component further includes a suction pump, and the suction pump is used to suck the ink located in the nozzle.

[0009] In this solution, the suction pump can suck out the ink remaining in the nozzle, reducing the risk of unclear spray code caused by the drying of the ink in the nozzle, further improving the cleaning ability of the nozzle, and improving the reliability and stability of the spray assembly.

[0010] In this solution, the suction pump is connected to the cleaning body and is used to suck the ink on the nozzle into the cleaning body.

[0011] In this solution, during the process of the suction pump sucking ink, the ink can flow into the cleaning body through the suction pump and be absorbed by the cleaning body which is a sponge, that is, the sucked ink can be absorbed and stored by the cleaning body, further reducing the risk of ink dripping from the cleaning body during the cleaning process.

[0012] In this solution, the cleaning component further comprises a shell, and the cleaning body and the suction pump are located inside the shell.

[0013] In this solution, the shell is located at the periphery of the cleaning component, which can prevent the cleaning body from contacting with external dust and prevent the ink absorbed by the cleaning body from drying up, so as to facilitate recycling.

[0014] In this solution, the cleaning component is movably connected to the base, and the spraying equipment further includes a first driving member, which is connected to the cleaning component and is used to drive the cleaning component to move relative to the spraying component.

[0015] In this solution, the first driving member can drive the cleaning assembly to move away from or closer to the spraying assembly. When the nozzle of the spraying assembly needs to be cleaned after spraying, the cleaning assembly and the spraying assembly are driven by the first driving member to move closer to each other so that the cleaning body can contact and clean the nozzle, so that the nozzle can be used for the next spraying, and the convenience of cleaning the spraying assembly can be improved.

[0016] In this solution, the spraying equipment further includes a driving assembly, which is connected to the spraying assembly and is used to drive the spraying assembly to move along the first direction and the second direction.

[0017] In this solution, the driving component drives the spraying component to move relative to the base in the first direction and the second direction so that the nozzle sprays the first barcode. When the photovoltaic module preparation step is in the eighth step, after the spraying device receives the spraying signal, the driving component drives the spraying component to move relative to the base in the first direction and the second direction so that the nozzle sprays the second barcode. Therefore, by setting the driving component, the spraying component can be controlled to move in the first direction and the second direction, which is conducive to improving the convenience of using the spraying device, and further conducive to improving the automation and production efficiency of photovoltaic module production.

[0018] In this solution, the spraying equipment further comprises a detection member, which is installed in the ink cartridge and is used to detect the liquid level of the ink in the ink cartridge.

[0019] In this solution, an indicator light can be provided on the outside of the ink cartridge, and the indicator light is connected to the detection component signal. When the ink in the ink cartridge is at the lowest liquid level, the detection component transmits a signal to light up the indicator light and alarm, so that ink can be added to the spray equipment in time, which is beneficial to improve the reliability and convenience of the spray equipment.

[0020] According to a second aspect of the present application, there is provided a photovoltaic module, comprising a stacked cover plate, a battery module and a back plate, wherein the surface of the cover plate facing the battery module has a first barcode, and the surface of the back plate facing away from the battery module has a second barcode, and the first barcode and the second barcode are sprayed by the above-mentioned spraying equipment.

[0021] In this solution, the first barcode located on the side of the cover plate facing the battery assembly can be used to record the information of the photovoltaic assembly, thereby facilitating the identification and tracking of the photovoltaic assembly. The second barcode located on the side of the back plate away from the battery assembly can also record the information of the photovoltaic assembly, thereby facilitating tracking during the production of the photovoltaic assembly, thereby facilitating the grasp of the quality of the photovoltaic assembly. In addition, the use of spraying equipment to spray the photovoltaic assembly can make the production process of the photovoltaic assembly more automated, thereby helping to improve the efficiency of photovoltaic assembly production. At the same time, it can avoid the problems of wrinkling, skewing, bubbling, etc. of the barcode caused by manually pasting the barcode, thereby helping to improve the compactness of the photovoltaic assembly structure and reduce the risk of degradation and poor appearance of the photovoltaic assembly. On the other hand, it can reduce the risk of hidden cracks between the photovoltaic assembly and the barcode pasting position.

[0022] In this embodiment, the battery assembly includes multiple battery strings, the battery strings include multiple electrically connected battery cells, the battery assembly also includes a first bus bar located at the edge of the battery assembly, the projection of the first barcode is located on the first bus bar, and / or the second barcode is located in the middle of the back panel.

[0023] In this solution, the projection of the first barcode on the side of the cover plate facing the battery assembly can be located on the first bus bar and located near the positive pole of the photovoltaic assembly. At this time, the first barcode is located at the first position. Spraying the first barcode at the first position can make the first barcode more eye-catching and facilitate the operator to scan the first barcode. The second barcode is sprayed on the middle of the surface of the back plate away from the battery assembly. At this time, the second barcode is located at the second position in the middle of the back plate. Spraying the second barcode at the second position can improve the aesthetics of the photovoltaic assembly and the convenience of scanning.

[0060] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0061] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] In a specific embodiment, the present application is further described in detail below through a specific embodiment and in conjunction with the accompanying drawings.

[0063] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0064] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0065] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0066] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0067] At present, in the production process of photovoltaic modules, barcodes for tracing module information are usually pasted on photovoltaic modules to record and track photovoltaic module information, so as to facilitate monitoring of the quality of photovoltaic module production. However, the manual pasting of barcodes for photovoltaic module identification is not conducive to improving the production efficiency of photovoltaic modules. At the same time, due to the different strengths of manual barcode pasting, there is a risk of hidden cracks at the location where the barcode is pasted, and the manual barcode pasting method is also prone to problems such as barcode wrinkles, barcode skewness, and barcode bubbling, which can easily increase the risk of photovoltaic modules being degraded and having poor appearance.

[0068] To this end, this embodiment provides a photovoltaic module 2 to solve the above technical problems. Figure 1 and Figure 2 As shown, the photovoltaic module 2 includes a stacked cover plate 21, a battery module 22 and a back plate 23. The photovoltaic module 2 is sprayed with a spraying device 1. In a specific embodiment, Figure 3 and Figure 4As shown, the first barcode 211 is sprayed on the surface of the cover plate 21 facing the battery assembly 22 by using the spraying device 1, and the second barcode 231 can also be sprayed on the surface of the back plate 23 facing away from the battery assembly 22 by using the spraying device 1. Among them, the first barcode 211 located on the side of the cover plate 21 facing the battery assembly 22 can be used to record the information of the photovoltaic assembly 2, thereby facilitating the identification and tracking of the photovoltaic assembly 2. The second barcode 231 located on the side of the back plate 23 facing away from the battery assembly 22 can also record the information of the photovoltaic assembly 2, thereby facilitating the tracking during the production process of the photovoltaic assembly 2, thereby facilitating the grasp of the quality of the photovoltaic assembly 2.

[0069] In this embodiment, the use of the spraying device 1 to spray the photovoltaic module 2 can make the production process of the photovoltaic module 2 more automated, thereby helping to improve the production efficiency of the photovoltaic module 2. At the same time, it can avoid the problems of wrinkles, skewness, bubbles, etc. of the barcode caused by manual barcode pasting, thereby helping to improve the compactness of the structure of the photovoltaic module 2, reduce the risk of degradation and poor appearance of the photovoltaic module 2, and on the other hand, reduce the risk of hidden cracks between the photovoltaic module 2 and the barcode pasting position.

[0070] Among them, Figure 1 As shown, since sunlight needs to be incident from the surface of the cover plate 21 facing away from the battery assembly 22, the cover plate 21 is generally made of transparent glass so that the cover plate 21 has good light transmittance, that is, the first barcode 211 located on the surface of the cover plate 21 facing the battery assembly 22 can be displayed from the other side surface where sunlight is incident, so that the first barcode 211 can be used to scan the information of the photovoltaic assembly 2.

[0071] like Figure 3 and Figure 4 As shown, the battery assembly 22 includes a plurality of battery strings 221, the battery string 221 includes a plurality of electrically connected battery cells 221a, the battery assembly 22 also includes a bus bar 222, the bus bar 222 connects the plurality of battery strings 221, the bus bar 222 includes a first bus bar 222a, wherein the first bus bar 222a is located at the edge of the battery assembly 22. The projection of the first barcode 211 is located on the first bus bar 222a; and / or, the second barcode 231 is located in the middle of the back plate 23.

[0072] In this embodiment, the projection of the first barcode 211 located on the side of the cover plate 21 facing the battery assembly 22 can be located on the first bus bar 222a and located near the positive electrode of the photovoltaic assembly 2, that is, Figure 3 As shown in the first barcode 211 , at this time, the first barcode 211 is located at the first position. Spraying the first barcode 211 at the first position can make the first barcode 211 more eye-catching, so that the operator can scan the first barcode 211 more easily.

[0073] In other embodiments, the first barcode 211 can also be located at any one of the other three corners of the first bus bar 222a close to the photovoltaic component 2, that is, the first barcode 211 can be located at any one of the four corners of the photovoltaic component 2, so that the first barcode 211 is more eye-catching and easy to scan.

[0074] like Figure 4 As shown, the second barcode 231 is sprayed on the middle of the surface of the back panel 23 facing away from the battery assembly 22. At this time, the second barcode 231 is located at the second position in the middle of the back panel 23. Spraying the second barcode 231 at the second position can improve the aesthetics of the photovoltaic assembly 2 and the convenience of scanning.

[0075] In one possible implementation, the bus bar 222 further includes a second bus bar 222b, which is located between the two first bus bars 222a, that is, the second bus bar 222b is located inside the first bus bar 222a. The projection of the second barcode 231 may also be located on the second bus bar 222b.

[0076] In a possible implementation, Figure 5 As shown, the above-mentioned photovoltaic module 2 can be formed by the following steps: the first step, glass loading: fix the cover plate 21 in the position for spraying by the spraying equipment 1. The second step, the manufacturing execution system (Manufacturing Execution System, MES system) sends a spraying signal to the spraying equipment 1, and the spraying equipment 1 moves to the first position after receiving the signal and sprays ink to form a first bar code 211 on the cover plate 21. The third step, a layer of adhesive film is laid: the first layer of adhesive film is laid on the surface of the cover plate 21 sprayed with the first bar code 211. The fourth step, series welding: the battery cells 221a are welded in series to form a battery string 221. The fifth step, lap welding: overlap parts of adjacent battery strings 221 to form a battery assembly 22. Then, the battery assembly 22 is laid on the first layer of adhesive film. The sixth step, the second layer of adhesive film is laid: the second layer of adhesive film is laid on the battery assembly 22. The seventh step is glass bonding: lay the back panel 23 on the second adhesive film, and stack the cover panel 21, the first adhesive film, the battery assembly 22, the second adhesive film, and the back panel 23 in sequence. The eighth step is that the MES system sends a spraying signal to the spraying device 1. After receiving the signal, the spraying device 1 moves to the second position and sprays ink to form a second barcode 231 on the surface of the back panel 23 away from the cover panel 21. The ninth step is pre-layer EL (electroluminescence defect detection): used to detect internal defects of the battery cell 221a. The tenth step is lamination: the cover panel 21, the first adhesive film, the battery assembly 22, the second adhesive film, and the back panel 23 are pressed together by a laminator.

[0077] Specifically, during the process of laminating the photovoltaic module 2, the laminator can perform low-temperature baking on the photovoltaic module 2, and the baking temperature is generally 100°C-500°C, so that the ink and the glass can be firmly fused together, that is, the first barcode 211 and the second barcode 231 can be firmly combined with the cover plate 21 and the back plate 23. At the same time, after low-temperature baking, the barcode encoding is clearer, easy to scan, and not easy to fade, reducing the risk of barcode damage to the photovoltaic module 2 after long-term use.

[0078] In addition, after spraying the first barcode 211, it can be scanned and read, and then in a subsequent step, the second barcode 231 can be sprayed onto the back panel 23 to ensure the consistency of the barcode information inside and outside the photovoltaic group, that is, the consistency of the first barcode 211 and the second barcode 231 information, thereby reducing the risk of inconsistency in the internal and external barcode information caused by manual barcode pasting.

[0079] In order to form the first barcode 211 and the second barcode 231 on the photovoltaic module 2, the embodiment of the present application further provides a spraying device 1, such as Figure 6 As shown, the spraying device 1 includes a base 11, a spraying assembly 12 and a cleaning assembly 13. The spraying assembly 12 is installed on the base 11. The spraying assembly 12 includes an ink cartridge 121 and a nozzle 122 connected to the ink cartridge 121. The ink cartridge 121 is used to store ink, and the nozzle 122 is used to spray ink. The cleaning assembly 13 includes a cleaning body 131, and the cleaning body 131 is used to clean the nozzle 122.

[0080] When the spraying device 1 is used to spray the barcode, the MES system sends a signal to control the spraying component 12 of the spraying device 1 to move to the spraying position and then spray. Specifically, after receiving the signal, the spraying device 1 controls the ink in the ink cartridge 121 to be sprayed out through the nozzle 122. After the spraying component 12 sprays the barcode on the photovoltaic module 2, the spraying component 12 and the cleaning component 13 move closer to each other, so that the cleaning body 131 can clean the residual ink and external dust on the nozzle 122, improve the cleanliness of the nozzle 122, and avoid the ink remaining on the nozzle 122 from affecting the next spraying of the barcode by the spraying component 12, which is beneficial to improve the clarity of the barcode, and further help to improve the reliability and convenience of the spraying component 12, so as to improve the efficiency of the spraying device 1 for spraying the photovoltaic module 2, and further improve the efficiency of the production of the photovoltaic module 2.

[0081] The ink cartridge 121 and the nozzle 122 may be an integrated structure, which is beneficial to reducing the production cost of the spraying equipment 1 .

[0082] In a possible implementation, Figure 6 As shown, the spraying device 1 further includes a detection component (not shown in the figure), which is installed in the ink cartridge 121 and is used to detect the liquid level of the ink in the ink cartridge 121 .

[0083] Specifically, an indicator light (not shown in the figure) can be provided on the outside of the ink cartridge 121, and the indicator light is connected to the detection component signal. When the ink in the ink cartridge 121 is at the lowest liquid level, the detection component transmits a signal to make the indicator light up and alarm, so that ink can be added to the spraying equipment 1 in time, which is beneficial to improve the reliability and convenience of the operation of the spraying equipment 1.

[0084] Among them, the detection component can be a float detection component. The present application does not limit the detection component, as long as it can detect the ink level in the ink cartridge 121.

[0085] In a possible implementation manner, the cleaning body 131 is made of sponge.

[0086] In this embodiment, since the sponge is absorbent, the ink can be absorbed into the cleaning body 131 during the process of the cleaning body 131 wiping the residual ink at the nozzle 122, which is beneficial to improving the cleaning ability of the cleaning body 131 to clean the ink and can reduce the risk of ink dripping during the wiping process of the cleaning body 131.

[0087] In a possible implementation, Figure 8 As shown, the cleaning assembly 13 further includes a suction pump 132 , and the suction pump 132 is used to suck the ink located at the nozzle 122 .

[0088] In this embodiment, the suction pump 132 can suck the residual ink in the nozzle 122, reducing the risk of unclear spray code caused by the ink in the nozzle 122 drying up, further improving the cleaning ability of the nozzle 122, and improving the reliability and stability of the spray assembly 12.

[0089] In a possible implementation, Figure 8 As shown, the suction pump 132 is connected to the cleaning body 131 and is used to suck the ink on the nozzle 122 into the cleaning body 131 .

[0090] In this embodiment, during the process of the suction pump 132 sucking ink, the ink can flow into the cleaning body 131 through the suction pump 132 and be absorbed by the cleaning body 131 which is a sponge, that is, the sucked ink can be absorbed and stored by the cleaning body 131, further reducing the risk of ink dripping from the cleaning body 131 during the cleaning process.

[0091] In a possible implementation, Figure 8 As shown, the cleaning assembly 13 further includes a shell 133 , and the cleaning body 131 and the suction pump 132 are located in the shell 133 .

[0092] In this embodiment, the shell 133 is located at the periphery of the cleaning assembly 13, and can prevent the cleaning body 131 from contacting with external dust, and prevent the ink absorbed by the cleaning body 131 from drying up, so as to facilitate recycling. In addition, in a possible implementation, the shell 133 includes an absorption chamber (not shown in the figure) connected to the cleaning body 131. When the cleaning body 131 absorbs a lot of ink, the water absorption performance of the cleaning body 131 is reduced, and there is a risk of ink leakage. The absorption chamber can absorb the ink that is about to leak in the cleaning body 131, thereby avoiding the risk of leakage of the sucked ink, which is conducive to improving the reliability of the cleaning assembly 13.

[0093] In a possible implementation, Figure 6 As shown, the spraying device 1 further includes a driving assembly 15, which is connected to the spraying assembly 12 and is used to drive the spraying assembly 12 to move along the first direction X and the second direction Y.

[0094] When the preparation step of the photovoltaic module 2 is in the second step, after the spraying device 1 receives the MES signal, the driving component 15 drives the spraying component 12 to move relative to the base 11 along the first direction X and the second direction Y, so that the ink sprayed by the nozzle 122 can be in the first position, thereby forming the first barcode 211. When the preparation step of the photovoltaic module 2 is in the eighth step, after the spraying device 1 receives the MES signal, the driving component 15 drives the spraying component 12 to move relative to the base 11 along the first direction X and the second direction Y, so that the ink sprayed by the nozzle 122 can be in the second position, thereby forming the second barcode 231. Therefore, by setting the driving component 15, the spraying component 12 can be controlled to move along the first direction X and the second direction Y, which is conducive to improving the convenience of using the spraying device 1, and further conducive to improving the automation and production efficiency of the production of the photovoltaic module 2.

[0095] It should be noted that the first direction and the second direction mentioned in this application can refer to Figure 6 In the embodiment shown, the first direction is X and the second direction is Y. In a specific embodiment, the first direction X may be the width direction of the base 11 and the second direction Y may be the length direction of the base 11. Therefore, the first direction X and the second direction Y are perpendicular to each other.

[0096] In a possible implementation, Figure 6 As shown, the cleaning assembly 13 is movably connected to the base 11 , and the spraying device 1 further comprises a first driving member 14 , which is connected to the cleaning assembly 13 and is used to drive the cleaning assembly 13 to move relative to the spraying assembly 12 .

[0097] Specifically, the first driving member 14 can drive the cleaning assembly 13 to move relative to the base 11 along the first direction X and the second direction Y, that is, the cleaning assembly 13 can be relatively far away from or close to the spray assembly 12. When the nozzle 122 of the spray assembly 12 needs to be cleaned after spraying, the cleaning assembly 13 and the spray assembly 12 are driven by the first driving member 14 to move closer to each other, so that the cleaning body 131 can contact and clean the nozzle 122, so that the nozzle 122 can be used for the next spraying, and the convenience of cleaning the spray assembly 12 can also be improved.

[0098] In addition, in Figure 6 In the embodiment shown, during the spraying process of the spraying assembly 12, the cleaning assembly 13 can move to a position close to the base 11 to reduce the risk of obstructing the spraying of the spraying assembly 12. At the same time, after the spraying assembly 12 is finished, the spraying assembly 12 can move toward the cleaning assembly 13, or the cleaning assembly 13 moves toward the spraying assembly 12, or the spraying assembly 12 and the cleaning assembly 13 can move toward each other, so as to be set according to actual needs, that is, the present application does not limit the process of the spraying assembly 12 and the cleaning assembly 13 moving relative to each other, as long as the cleaning assembly 13 can clean the nozzle 122.

[0099] like Figure 6 In the illustrated embodiment, the driving assembly 15 includes a second driving member 152 and a first slide bar 151, the second driving member 152 is a driving motor, and the spraying assembly 12 is slidably connected to the first slide bar 151, so that the spraying assembly 12 can move relative to the first slide bar 151 along the first direction X. The base 11 can be provided with a slide rail, and both ends of the first slide bar 151 include a first slider 151a, and the spraying assembly 12 is slidably connected to the base 11 through the first slider 151a on the first slide bar 151. The second driving member 152 can drive the spraying assembly 12 to move relative to the first slide bar 151 along the first direction X, and can also drive the first slide bar 151 to move relative to the base 11 along the second direction Y, so that the spraying assembly 12 can move relative to the base 11 along both the first direction X and the second direction Y. In addition, the spraying device 1 further includes a second slide bar 16, and the cleaning assembly 13 is slidably connected to the second slide bar 16, so that the cleaning assembly 13 can move relative to the second slide bar 16 in the first direction X, and both ends of the second slide bar 16 include second sliders (not shown in the figure), so that the cleaning assembly 13 is slidably connected to the base 11 through the second sliders on the second slide bar 16.
