Description

Technical Field

[0001] This invention belongs to the field of photovoltaic equipment technology and relates to a busbar film applicator. Background Technology

[0002] As the application scope of solar photovoltaic modules becomes wider and wider, more and more customers are demanding higher photoelectric conversion efficiency and appearance of photovoltaic modules.

[0003] To improve the conversion efficiency and aesthetics of photovoltaic (PV) modules, the busbars on these modules need to be treated. Traditionally, this is achieved by painting or applying a film to the busbars. For example, in an all-black PV module, the cells, frame, and backsheet are all made of black materials, and to achieve the all-black effect, the busbars also need to be black. Common methods for manufacturing black busbars involve painting a layer of black paint or applying a black film to a silver busbar. However, the former is more expensive to produce, and black paint is non-conductive; furthermore, the paint needs to be scraped off when making the leads, which is quite troublesome. Therefore, customers prefer the method of applying a film to the busbars.

[0004] Currently, the film is usually applied manually by workers to the side of the busbar facing the glass. This method is inefficient and the quality of the film application is inconsistent. Summary of the Invention

[0005] To address the problems in the related technologies, this application provides a busbar film applicator, which can automatically apply film to the busbars on photovoltaic modules, improving the efficiency and quality of film application and saving manpower.

[0006] This application provides a busbar laminating machine for laminating films onto the busbars of photovoltaic modules. The busbar laminating machine includes a module conveying section, a module picking section, at least one film strip feeding section, at least one film strip conveying section, and at least one film strip pressing section.

The film strip feeding section is used to provide film strips. The film strip conveying section includes a moving device and a receiving heating device. The moving device is used to drive the receiving heating device to receive the film strip from the film strip feeding section and to drive the receiving heating device to move the film strip to below the busbar of the photovoltaic module picked up by the module picking section. The receiving heating device is also used to heat the film strip. The film strip pressing section is located above the module conveying section and is used to press and bond the busbar on the photovoltaic module to the film strip located below the busbar.

The photovoltaic module is picked up through the module picking unit to create a space for film strip conveying below the photovoltaic module. The film strip feeding unit realizes automatic feeding of film strips. The film strip conveying unit realizes conveying film strips to the busbars of the photovoltaic module. The receiving heating device realizes the support and heating of film strips. The film strip pressing unit realizes pressing and bonding of the busbars on the photovoltaic module with the film strips below the busbars. Through the cooperation of the above components, the automatic film application to the busbars on the photovoltaic module is realized, improving the film application efficiency and quality and saving manpower.

Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0049] Photovoltaic modules are made up of strings of cells laid side by side. They are generally classified as full-cell modules and half-cell modules. Full-cell modules consist of whole cell strings, while half-cell modules consist of half cell strings. A half-cell string is made by welding together smaller pieces of a whole cell string, which are approximately half the length of the whole cell string. Both half-cell and full cell strings have extended solder strips at their ends for welding to busbars. The busbars collect the current generated by each cell string and output it through a junction box.

[0050] like Figure 8The half-cell photovoltaic module shown includes a first cell string group 1 and a second cell string group 2. Multiple cell strings are arranged side-by-side in both the first and second cell string groups 1 and 2. The busbar at the end of the first cell string group 1 furthest from the second cell string group 2 is the first-end busbar 3. The busbar between the first and second cell string groups 1 and 2 is the middle busbar 4. The busbar at the end of the second cell string group 2 furthest from the first cell string group 1 is the last-end busbar 5. Applying film to the busbars involves attaching film strips below the first-end busbar 3, the middle busbar 4, and the last-end busbar 5. To lead the busbars to the junction box, the middle busbar is bent upwards, forming a bend 41.

[0051] Traditional busbar film application is done manually. After lifting the battery string, the film is pasted on the side of the busbar facing the glass. This method is inefficient and the film quality is inconsistent.

[0052] Therefore, this application provides a busbar film application machine for applying film to the busbars of photovoltaic modules, such as... Figure 1 , Figure 2 , Figure 3 As shown, the busbar laminating machine includes a component conveying section 6, a component picking section 7, at least one film strip feeding section 8, at least one film strip conveying section 9, and at least one film strip pressing section 10. The component conveying section 6 is used to convey a glass plate carrying photovoltaic modules. The component picking section 7 is located above the component conveying section 6 and is configured to pick up photovoltaic modules from the glass plate. The film strip feeding section 8 is used to provide film strips. The film strip conveying section 9 includes a moving device and a receiving heating device. The moving device is used to drive the receiving heating device to receive the film strip from the film strip feeding section 8 and to drive the receiving heating device to move the film strip to below the busbar of the photovoltaic module picked up by the component picking section 7. The receiving heating device is also used to heat the film strip. The film strip pressing section 10 is located above the component conveying section 6 and is used to press and bond the busbar on the photovoltaic module to the film strip located below the busbar.

[0053] In one implementation, the busbar film applicator includes a frame 11, on which a component conveying unit 6 is mounted. The component conveying unit 6 includes a component conveyor belt 601, conveyor belt support wheels, conveyor belt drive wheels, and a component drive device 602. The conveyor belt support wheels and conveyor belt drive wheels are mounted on the frame 11. The drive end of the component drive device 602 is connected to the conveyor belt drive wheels to drive the conveyor belt drive wheels to rotate, thereby driving the component conveyor belt 601 to rotate. The component conveyor belt 601 moves the glass plate and the photovoltaic modules placed on the glass plate to the film applicator station. In one implementation, the component drive device 602 can be a motor; to achieve more stable transport of the glass plate, the component conveyor belt 601 can be multiple parallel belts.

[0054] The component picking unit 7 is installed on the frame 11 above the component conveying unit 6. When the component conveying unit 6 transports the glass plate and photovoltaic module to the film application station, the component picking unit 7 descends, picks up the photovoltaic module, and drives the photovoltaic module upward away from the glass plate, forming a channel for conveying the film strip between the photovoltaic module and the glass plate.

[0055] The film strip feeding unit 8 is installed on the side of the component conveying unit 6 of the frame 11 in the conveying direction. The film strip feeding unit 8 is used to pull and cut the film strip and to provide the film strip to the film strip conveying unit 9. The film strip conveying unit 9 includes a moving device and a receiving heating device. The receiving heating device is installed on the moving device, which is movably installed on the frame 11 above the component conveying unit 6 and can move between the receiving station for receiving film strips and the pressing station for pressing film strips. The film strip feeding unit 8 places the film strip onto the receiving heating device. After the film strip feeding unit 8 has supplied the film strip, the moving device drives the receiving heating device to move the film strip below the first busbar 3, the middle busbar 4, and the last busbar 5 of the photovoltaic module. Then, the moving device can lift the film strip to fit closer to the busbars, or the module picking unit 7 can lower the photovoltaic module, so that the first busbar 3 fits with the first film strip, the middle busbar 4 fits with the middle film strip, and the last busbar 5 fits with the last film strip. The film strip pressing unit 10 descends to press the film strip and the corresponding busbar together. The receiving heating device can preheat the film strip during the film strip feeding process and heat the film strip when it is pressed and bonded to the busbars, helping to release the film strip's stickiness and improving the pressing and bonding efficiency of the film strip and the busbars.

[0056] The busbar film applicator of this application realizes the conveying and feeding of photovoltaic modules through the module conveying unit 6, the picking up of photovoltaic modules through the module picking unit 7 to form a space for film strip conveying below the photovoltaic modules, the automatic feeding of film strips through the film strip feeding unit 8, the conveying of film strips to the busbars of photovoltaic modules through the film strip conveying unit 9, the bearing and heating of film strips through the receiving heating device, and the pressing unit 10 to press and bond the busbars on the photovoltaic modules with the film strips below the busbars. Through the cooperation of the above components, the automatic application of film to the busbars on the photovoltaic modules is realized, improving the film application efficiency and quality and saving manpower.

[0057] In one implementation, such as Figure 4 and Figure 5As shown, the receiving heating device includes a heating part, a support plate 901, and multiple guide post groups; the heating part is connected to the support plate 901 and is used to heat the support plate 901; the support plate 901 is provided with a film strip placement station for placing film strips, and multiple guide post groups are spaced apart along the length direction of the support plate 901; the guide post group includes a first guide post 902 and a second guide post 903 arranged in a one-to-one correspondence, the first guide post 902 is located on the first side of the film strip placement station, and the second guide post 903 is located on the second side of the film strip placement station.

[0058] Optionally, the support plate 901 is provided with mounting holes, and the heating element is mounted onto the support plate 901 through the mounting holes. The heating element can be a heating rod. A guide post assembly is provided at the membrane strip placement station. The guide post assembly includes a pair of first guide posts 902 and second guide posts 903. For easy guidance, both the first guide post 902 and the second guide post 903 can be tapered.

[0059] In one implementation, the guide post is mounted onto the support plate 901 through the guide post mounting hole 904. The support plate 901 is provided with multiple sets of guide post mounting holes 904 with different spacings. The first guide post 902 and the second guide post 903 can be adjusted to be mounted in the guide post mounting holes 904 with different spacings to guide the membrane strips of different widths.

[0060] The support plate 901 is used to receive the film strip, and the heating unit heats the support plate 901, thereby preheating the film strip at the film strip placement station and heating it during film strip pressing. This helps the film strip release its stickiness and improves the pressing efficiency. The guide post assembly guides and limits the film strip at the film strip placement station, ensuring the accuracy of film strip feeding.

[0061] In one implementation, the heating device further includes a guide column lifting device 905. The driving end of the guide column lifting device 905 is connected to the first guide column 902 and the second guide column 903. The guide column lifting device 905 is used to drive the first guide column 902 and the second guide column 903 in the guide column group to rise and fall.

[0062] A guide column lifting device 905 is installed below the support plate 901, and the driving end of the guide column lifting device 905 is connected to the first guide column 902 and the second guide column 903 in the guide column mounting hole 904. In one implementation, the guide column lifting device 905 is a cylinder.

[0063] The guide column lifting device 905 controls the rise and fall of the guide column assembly. When the heating device receives and transports the membrane strip, the guide column assembly rises to guide and limit the membrane strip. When the membrane strip and the busbar approach each other, the guide column assembly falls to avoid contact with the solar cells in the photovoltaic module, thus preventing damage to the solar cells.

[0064] In one implementation, the membrane strip placement station is provided with strip-shaped protrusions 906 for supporting the membrane strip, and the strip-shaped protrusions 906 are provided with negative pressure adsorption holes 907 for adsorbing and positioning the membrane strip. The strip-shaped protrusions 906 are disposed on the support plate 901 to support the membrane strip, and the arrangement of the strip-shaped protrusions 906 facilitates more precise adhesion of the membrane strip to the busbar.

[0065] The strip protrusions 906 enable the individual bonding of the membrane strip and the busbar, preventing interference between the rest of the carrier plate 901 and the cell strings in the photovoltaic module. The negative pressure adsorption holes 907 ensure that the membrane strip is tightly attached to the strip protrusions 906, guaranteeing the feeding accuracy of the membrane strip.

[0066] In one implementation, the moving device includes a moving track 911 and a driving device; the moving track 911 is mounted on the frame 11 of the component conveying section 6, and the length direction of the moving track 911 is perpendicular to the conveying direction of the component conveying section 6; the receiving heating device is slidably mounted on the moving track 911, and the driving device is connected to the receiving heating device, and the driving device is used to drive the receiving heating device to move along the moving track 911.

[0067] In one implementation, the receiving heating device includes a support plate 901 and a movable bracket 908. The support plate 901 is mounted on the movable bracket 908, which is mounted on a movable track 911. The driving device includes a drive motor 909, a gear 910, and a rack. The movable track 911 is a slide rail, which is mounted on the frame 11. A slider 912 that cooperates with the slide rail is mounted on the movable bracket 908. The rack is mounted parallel to the slide rail on the frame 11. The drive motor 909 and the gear 910 are mounted on the movable bracket 908. The drive end of the drive motor 909 is connected to the gear 910. The drive motor 909 drives the gear 910 to move along the rack, thereby moving the film strip between the receiving station and the pressing station.

[0068] The drive device enables the conveying of the film strip from the heating device, and the moving track 911 guides the movement of the heating device.

[0069] In one implementation, such as Figure 6 , Figure 7 As shown, the membrane strip pressing part 10 includes a lifting drive device and a pressing head device. The driving end of the lifting drive device is connected to the pressing head device. The lifting drive device is used to drive the pressing head device to lift and lower. The pressing head device is used to press and bond the busbar and the membrane strip together.

[0070] The lifting drive device is installed on the frame 11 above the component conveying section 6, and the drive end of the lifting drive device is connected to the pressure head device. The lifting drive device can be driven by a motor or a cylinder.

[0071] The lifting drive device enables the lifting of the pressure head device, and the pressure head device enables the pressing and bonding of the manifold strip and the membrane strip.

[0072] In one implementation, the pressure head device includes a pressure head support 1001 and a plurality of pressure blocks 1002 arranged side-by-side and spaced apart below the pressure head support 1001; the pressure head support 1001 is connected to the drive end of the lifting drive device; the pressure blocks 1002 are installed below the pressure head support 1001 via connectors. The arrangement of multiple pressure blocks at intervals allows for avoidance of the intermediate busbar bend 41.

[0073] In one implementation, the bottom of the pressure head bracket 1001 is provided with a strip-shaped through groove along the length direction. The connecting component includes a bolt, which is installed in the strip-shaped through groove. The position of the bolt in the strip-shaped through groove can be adjusted, so the installation position of the pressure head and the spacing between the pressure heads can also change with the position of the bolt to meet the needs of photovoltaic modules of different specifications.

[0074] The pressure head bracket 1001 provides support for the connector, and the connector allows the pressure block 1002 to be installed on the pressure head bracket 1001. The spacing of the pressure blocks 1002 avoids the bending parts of the busbar. The strip-shaped through groove at the bottom of the pressure head bracket 1001 allows for arbitrary adjustment of the position of the pressure block 1002, thus meeting the film application requirements of busbars with different component specifications.

[0075] In some other embodiments, the connector includes a connecting plate 1003, a guide post 1004, and a spring 1005; the connecting plate 1003 is fixedly installed below the pressure head bracket 1001, and the lower end of the guide post 1004 slides through the connecting plate 1003 and is fixedly connected to the pressure block 1002; the spring 1005 is fitted on the guide post 1004, the first end of the spring 1005 abuts against the pressure block 1002, and the second end of the spring 1005 abuts against the connecting plate 1003.

[0076] As mentioned above, a strip-shaped through groove can be provided below the pressure head bracket 1001. The connecting plate 1003 can be installed in the strip-shaped through groove by bolts, thereby realizing the adjustment of the installation position of the pressure block 1002. After installation, the connecting plate 1003 is fixed below the pressure head bracket 1001. A limit device is provided at the upper end of the guide post 1004 to prevent the guide post 1004 from falling off the connecting plate 1003. The limit device can be a locking block set at the upper end of the guide post 1004, or it can be a guide sleeve 1006. The guide sleeve 1006 is installed on the connecting plate 1003, and the guide post 1004 is installed in the guide sleeve 1006. The guide post 1004 can slide up and down relative to the guide sleeve 1006. The spring 1005 is fitted on the guide post 1004. The first end of the spring 1005 abuts against the pressure block 1002, and the second end of the spring 1005 abuts against the guide sleeve 1006 or the connecting plate 1003.

[0077] Since there are multiple pressure blocks 1002, there may be height errors during installation. In order to ensure that all pressure blocks 1002 can press the busbars and membrane strips tightly, the lifting drive device drives the pressure head bracket 1001 to over-press when pressing down. Because springs and guide columns are set, it is ensured that the pressure blocks 1002 will not damage the busbars and photovoltaic modules even if they are over-pressed.

[0078] The installation of the guide post 1004 is achieved through the setting of the connecting plate 1003, and the installation of the pressure block 1002 is achieved through the setting of the guide post 1004 and the connecting plate 1003. The elastic downward pressing of the pressure block 1002 is achieved through the sliding connection between the guide post 1004 and the connecting plate 1003 and the setting of the spring 1005, ensuring that each pressure block can be effectively pressed.

[0079] In one implementation, the membrane strip pressing part 10 further includes a transverse movement device, the drive end of which is connected to a lifting drive device, and the transverse movement device drives the lifting drive device to move along a conveying direction perpendicular to the component conveying part 6.

[0080] In one implementation, the lifting drive device includes a lifting drive device 1007 and a lifting mounting frame 1008. The lifting drive device 1007 is mounted on the lifting mounting frame 1008, which is mounted on the frame 11 via a lateral movement device. The drive end of the lateral movement device is connected to the lifting mounting frame 1008, and the lateral movement device adjusts the position of the pressure block by driving the lifting mounting frame 1008 to move laterally. The lifting drive device 1007 can be either a motor or a cylinder. The lateral movement device can also be either a motor or a cylinder. Alternatively, the lateral movement device can be a lead screw 1010 and nut assembly driven by a lateral movement motor 1009. The lead screw 1010 is mounted on the frame 11, and the lifting mounting frame 1008 is mounted on the lead screw and nut. The lateral movement motor 1009 drives the lifting mounting frame 1008 to move on the lead screw 1010 to adjust its position.

[0081] In one implementation, in order to ensure that the pressure head bracket 1001 can move up and down smoothly, the pressure head bracket 1001 is mounted on the lifting mounting frame 1008 via the lifting slider slide rail pair 1011.

[0082] The horizontal movement device enables the adjustment of the position of the pressure block relative to the photovoltaic module, meeting the different requirements of the busbar position in different photovoltaic module types and improving the compatibility of the busbar laminating machine.

[0084] The film strip roll 804 is placed on the film supply device 801. The traction clamp 803 includes a traction moving device and a clamp. The clamp is used to clamp the film strip. Before traction, the support plate 901 of the film strip conveying section 9 moves to the film supply device 801 and aligns with it. The traction moving device drives the clamp to pull the film strip to the required length. During the film strip traction process, it is guided by the first guide post 902 and the second guide post 903. Then, the film strip is cut by the film cutting device 802 and adsorbed by the support plate 901. The traction moving device can be a linear motor. The film cutting device 802 includes a cutter and a cutter driving device. The cutter driving device drives the cutter to cut the film strip. The cutter driving device can be a cylinder.

[0085] The film supply device 801 enables the supply of film strips, the film cutting device 802 enables the cutting of film strips, and the traction clamp 803 enables the clamping, traction, and laying of film strips. The automatic feeding of film strips is achieved through the cooperation of the above components.

[0086] In one implementation, the component pickup unit 7 includes a suction cup assembly 702 and a component lifting device. The suction cup assembly 702 is installed on the drive end of the component lifting device, and the component lifting device is used to drive the suction cup assembly 702 to lift.

Multiple suction cup groups 702 are installed below the lifting frame 701, each corresponding to a battery string. Each suction cup group 702 is used to pick up one battery string. The pickup drive device 703 can be either a cylinder or a motor.

[0088] The suction cup assembly 702 enables the adsorption of photovoltaic modules, and the module lifting device enables the lifting of photovoltaic modules, providing space for the feeding of film strips.

[0089] The number of membrane strip feeding section 8, membrane strip conveying section 9, and membrane strip pressing section 10 can be adaptively selected according to the photovoltaic module type, equipment manufacturing cost, and film application efficiency. For whole modules with only first and last busbars, to achieve simultaneous film application to the first and last busbars, it is advisable to have two membrane strip conveying sections 9 and 10, and one or two membrane strip feeding sections 8. For half modules with first, middle, and last busbars, to achieve simultaneous film application to the first, middle, and last busbars, it is advisable to have three membrane strip conveying sections 9 and 10, and one, two, or three membrane strip feeding sections 8.

[0090] In one implementation, such as Figures 1 to 3 As shown, there are two film strip feeding units 8: a first film strip feeding unit located on the first side of the conveying direction of the component conveying unit 6 and a second film strip feeding unit located on the second side of the conveying direction of the component conveying unit 6.

Then the photovoltaic module descends to bring each busbar closer to the corresponding film strip. Finally, the first... The first membrane strip pressing part 1012, the second membrane strip pressing part 1013, and the third membrane strip pressing part 1014 simultaneously descend to apply the membrane to the busbars in the photovoltaic module. After the membrane application is completed, the first membrane strip pressing part 1012, the second membrane strip pressing part 1013, and the third membrane strip pressing part 1014 rise, and the photovoltaic module rises again.
