Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component production equipment, and in particular relates to a photovoltaic component production line. Background Art

[0002] At present, photovoltaic modules encapsulated with butyl adhesive include front glass, front adhesive film, battery cell, back adhesive film and back glass laid in order from top to bottom, and butyl adhesive is also applied in the gap between the front glass and the back glass to achieve water-proof sealing of the photovoltaic module. The existing process for realizing such photovoltaic modules is: firstly lay the front adhesive film on the front glass, then apply butyl adhesive around the edges of the front glass to surround the front adhesive film, then lay the battery cell, then lay the back adhesive film on the battery cell, and finally cover the back glass on the back adhesive film, while the butyl adhesive around the edges bonds and encapsulates the front glass and the back glass.

[0003] However, the traditional production process of photovoltaic modules does not require the application of butyl adhesive on the glass. If the traditional photovoltaic module production line is to be transformed according to the above-mentioned mainstream production process, it is necessary to make major changes to the traditional photovoltaic module production line, which makes the transformation cost very high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a photovoltaic module production line, which can produce photovoltaic modules encapsulated with butyl rubber without major changes to the traditional photovoltaic module main line, so as to overcome the shortcomings of the prior art.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A photovoltaic module production line includes a main line for producing photovoltaic module front units, and is characterized in that it also includes a secondary line for producing photovoltaic module back units, and the secondary line includes the following in order according to the transmission direction:

[0007] A glass conveying device, used for conveying the back glass;

[0008] A laminating device, used to cover a single back-side adhesive film on the back-side glass;

[0009] A positioning and fixing device, used for positioning and fixing the back adhesive film on the back glass;

[0010] A glue coating device, used for coating a circle of butyl glue around the back glue film on the back glass;

[0011] A flipping and glass-joining device for flipping the back unit of the photovoltaic module and covering the front unit of the photovoltaic module is also provided between the secondary line and the main line.

[0012] In a specific implementation of the utility model, the secondary line further comprises a film cutting device located next to the laminating device, and the film cutting device is used to cut the film roll into a single back film.

[0013] In a specific embodiment of the utility model, the flipping and glass-joining device includes a first conveying mechanism connected to the tail end of the secondary line, a second conveying mechanism inserted into the main line, and a flipping mechanism located between the first conveying mechanism and the second conveying mechanism, and the flipping mechanism is used to flip the back unit of the photovoltaic component conveyed to the first conveying mechanism and place it on the front unit of the photovoltaic component conveyed to the second conveying mechanism.

[0014] In a specific implementation of the present invention, the first conveying mechanism and the second conveying mechanism are both belt conveying mechanisms.

[0015] In a specific embodiment of the utility model, the flipping mechanism includes a rotating shaft, a flipping frame arranged on the rotating shaft, suction cups distributed on the flipping frame, and a driving motor for driving the rotating shaft to flip the flipping frame from the first conveying mechanism to the second conveying mechanism.

[0016] In a specific embodiment of the utility model, the transmission surface of the first transmission mechanism is provided with recesses spaced apart along the transmission direction, the flip frame has spaced support arms, the support arms are located in the recesses before flipping, and the suction cups are distributed on the upper surface of the support arms and are lower than the transmission surface of the first transmission mechanism. Such a structure allows the suction cups to wait below the transmission surface of the first transmission mechanism before flipping, and when the back unit of the photovoltaic module is transmitted to the transmission surface of the first transmission mechanism, the driving motor will drive the flip frame to rise upward, and the suction cups on the flip frame will first suck the back glass of the back unit of the photovoltaic module, and then the driving motor will continue to drive the flip frame to flip toward the second transmission mechanism until the back unit of the photovoltaic module is flipped and covered on the front unit of the photovoltaic module located on the second transmission mechanism.

[0017] It can be seen from the above detailed description that the main line still adopts the traditional photovoltaic module production line, and there is no need to make major changes to the main line. It only needs to insert the second transmission mechanism of the flipping and glass-sealing device into the main line, and only needs to configure the secondary line for producing the back unit of the photovoltaic module and the flipping and glass-sealing device to achieve the production of photovoltaic modules encapsulated with butyl rubber, which will not cause waste of traditional production lines and reduce the transformation cost.

The back unit of the photovoltaic module includes the back glass, the film fixed on the back glass and the butyl adhesive coated on the back glass and surrounding the film.

[0022] The main line 100 is a conventional production line for producing photovoltaic modules, and is used to produce the front units of photovoltaic modules, that is, to cover and fix the front adhesive film on the front glass, and to install the battery cells on the front adhesive film. Since it is in the prior art, it will not be described here.

[0023] The secondary line 200 is an additional production line of the present invention, which is used to produce the back unit of the photovoltaic module. It includes a glass transmission device 210, a film coating device 220, a positioning and fixing device 230, a glue coating device 240 in the transmission direction, and also includes a film cutting device 260 located next to the film coating device 220.

[0024] The glass transmission device 210 is used to transmit the back glass to the coating device 220. Since this device is a conventional transmission device using the prior art, it will not be described again here.

[0025] The film cutting device 260 is used to cut the film roll into a single back-side film. A conventional film cutting device in the prior art can be used, or a film cutting device described in the applicant's prior patent application with Chinese patent application number 202311716835.2 can be used, which will not be repeated here.

[0026] The laminating device 220 is used to cover a single back-side adhesive film on the back-side glass. A conventional laminating device in the prior art can be used, or a laminating device described in the applicant's prior patent application in China with patent application number 202311757015.8 can be used, which will not be described again here.

[0027] The positioning and fixing device 230 is used to position and fix the back adhesive film on the back glass. The conventional positioning and fixing device in the prior art can be used, or the positioning and fixing device recorded in the applicant's prior patent application in China with patent application number 202311757015.8 can be used, which will not be repeated here.

[0028] The gluing device 240 is used to apply a circle of butyl glue around the glue film on the back glass. A conventional gluing device in the prior art can be used, or a gluing device described in the applicant's prior patent application in China with patent application number 202311304744.8 can be used, which will not be repeated here.

[0029] The flipping and glass-joining device 300 is located between the secondary line 200 and the main line 100, and is used to flip the back unit of the photovoltaic module and cover it on the front unit of the photovoltaic module.

[0030] like Figure 2 As shown, in the present invention, the glass flipping and laminating device 300 includes a first conveying mechanism 310 receiving the tail end of the secondary line 200, a second conveying mechanism 320 inserted into the main line 100, and a flipping mechanism 330 located between the first conveying mechanism 310 and the second conveying mechanism 320.

[0031] In this embodiment, the first conveying mechanism 310 and the second conveying mechanism 320 are both belt conveying mechanisms, each of which is composed of a plurality of belt conveying units 340 that are spaced side by side and run synchronously.

[0032] The flip mechanism 330 includes a rotating shaft 331 , a flip frame 332 disposed on the rotating shaft 331 , suction cups 333 distributed on the flip frame 332 , and a driving motor 334 for driving the rotating shaft 331 to flip the flip frame 332 from the first conveying mechanism 310 to the second conveying mechanism 320 .

[0033] The transmission surfaces of the first transmission mechanism 310 and the second transmission mechanism 320 have two recesses 301 spaced apart along the transmission direction. The recesses 301 are realized by providing a steering wheel 341 in the belt transmission unit 340 to change the transmission direction of the belt. The flip frame 332 has two spaced apart support arms 302 corresponding to the two recesses 301. The two support arms 302 are located in the two recesses 301 before flipping, and a plurality of suction cups 333 are distributed on the upper surface of the support arms 302 and are lower than the transmission surface of the first transmission mechanism 310. Such a structure allows the suction cup 333 to wait below the transmission surface of the first conveying mechanism 310 before flipping. When the back unit of the photovoltaic module is conveyed to the transmission surface of the first conveying mechanism 310 (the back unit of the photovoltaic module located on the first conveying mechanism 310 is, from bottom to top, the back glass and the back film, and a circle of butyl rubber is coated around the back film on the back glass), the driving motor 334 will drive the flip frame 332 to rise upward, and the suction cup on the flip frame 332 will first suck the back glass of the back unit of the photovoltaic module, and then the driving motor 334 will continue to drive the flip frame 332 to flip toward the second conveying mechanism 320 until the back unit of the photovoltaic module is flipped and covered on the front unit of the photovoltaic module conveyed to the second conveying mechanism 320 (the front unit of the photovoltaic module located on the second conveying mechanism 320 is, from bottom to top, the front glass, the back film and the battery cell).

[0034] It can be seen from the above detailed description that the main line still adopts the traditional photovoltaic module production line, and there is no need to make major changes to the main line. It only needs to insert the second transmission mechanism of the flipping and glass-sealing device into the main line, and only needs to configure the secondary line for producing the back unit of the photovoltaic module and the flipping and glass-sealing device to achieve the production of photovoltaic modules encapsulated with butyl rubber, which will not cause waste of traditional production lines and reduce the transformation cost.
