Detailed Description

The present application is described in further detail below in conjunction with figures 1-4.

Referring to fig. 1, an embodiment of the present application discloses a film supplementing device, which is applied to a photovoltaic module in a photovoltaic power station, and the film supplementing device may include a first liquid storage device 2 for storing a film coating liquid; and the coating device 3 is communicated with the first liquid storage device 2, and the coating device 3 is used for spraying coating liquid on the surface of the photovoltaic module so as to supplement the film to the photovoltaic module.

Referring to fig. 1, in the embodiment of the present application, it is exemplarily described that the first liquid storage device 2 may be provided as a closed housing, and may be any one of a cylindrical shape, a rectangular parallelepiped shape, a polygonal prism shape, or the like, and this embodiment is exemplified by a cylindrical shape. The first liquid storage device 2 may be provided with a first liquid supplementing port 21 communicated with the first liquid storage device 2 so as to facilitate the addition of the coating liquid into the first liquid storage device 2. The first liquid storage device 2 may be provided in a tubular structure, and in this embodiment, the first liquid replenishing port 21 is vertically fixed to the top end of the first liquid storage device 2.

Referring to fig. 1, more specifically, the first fluid-filling port 21 may be provided with a first cover plate 22 that may be opened or closed to open or close the first fluid-filling port 21, for example, one side of the first cover plate 22 is hinged to the top end of the first fluid-filling port 21, and the other end of the first cover plate 22 is connected to the top end of the first fluid-filling port 21 through a latch or the like. The shape of the first cover plate 22 may be the same as the shape of the cross section of the first fluid-supplementing port 21, and in this embodiment, the first cover plate 22 may be provided in a circular shape. The first cover plate 22 is rotated to be opened, so that the coating liquid can be added into the first liquid storage device 2 through the first liquid supplementing port 21, and the first cover plate 22 is rotated to be closed, so that impurities such as dust can be prevented from entering the first liquid storage device 2 to pollute the coating liquid.

More specifically, the coating solution can be a coating solution capable of being cured at normal temperature, and can be cured at normal temperature without heating the coating solution at high temperature when a functional film (such as an antireflection film) is formed on the outer surface of the cover glass of the photovoltaic module, so that the coating process of the photovoltaic module is simpler and more convenient, and the film supplementing equipment can be suitable for outdoor places such as deserts, roofs, ridges and the like. The coating weight of the coating liquid on the photovoltaic module can be preferably 0.5-5.0 g/m ² . Hereinafter, the functional film will be described by taking an antireflection film as an example.

The film supplementing device can be applied to a photovoltaic power station and used for supplementing films to the coated photovoltaic modules, in other words, the film supplementing device can be used for carrying out secondary coating or multiple coating on the coated photovoltaic modules in the photovoltaic power station. When original functional film (such as antireflection film) on cover plate glass or back plate glass of photovoltaic module receives pollution or produces wearing and tearing, through the film supplementing equipment of this application behind to its film supplementing, can form new rete on cover plate glass or back plate glass to make its cover plate glass or back plate glass's function resume, such as make luminousness resume completely or partly resume, and then guarantee photovoltaic module's utilization efficiency to light.

It can also be appreciated that the film supplementing device of the present application can also perform film plating on an uncoated photovoltaic module, in other words, the film supplementing device of the present application can perform primary film plating on an uncoated photovoltaic module. When the photovoltaic module is not plated with an antireflection film, after the film is coated by the film supplementing equipment, a film layer can be formed on the cover plate glass so as to enhance the light transmittance of the cover plate glass.

In addition, because the film supplementing equipment in the prior art needs to thermally cure the film layer after film coating, and the thermal curing temperature is generally 80-120 ℃, the film supplementing equipment in the prior art needs to independently coat the cover glass or the back plate glass, and the coated cover glass or the coated cover glass and back plate glass are assembled and molded with the photovoltaic cell so as to obtain the single glass component or the double glass component, so that the performance of the photovoltaic cell is prevented from being influenced by high temperature when the assembled and molded single glass component or double glass component is directly coated. But this application both can carry out the coating film alone to cover glass or backplate glass to cover glass after will coating film or cover glass after will coating film and backplate glass and photovoltaic cell piece assembly forming in order to obtain single glass subassembly or dual glass subassembly, can directly carry out the coating film to single glass subassembly or dual glass subassembly that has assembled shaping again, consequently this application compares in prior art's film supplementing equipment and can be applicable to more kind photovoltaic products.

Referring to fig. 1 and 2, the plating device 3 may include a fixing plate 31; a driving mechanism 32 provided on the fixed plate 31; and a coating mechanism 33 connected to the driving mechanism 32 and movable on the fixed plate 31 by the driving mechanism 32.

In this embodiment, the fixing plate 31 may be configured as a rectangle, and the length and width of the fixing plate may be larger than those of the photovoltaic module, and it is understood that when the photovoltaic module is subjected to film-supplementing, the fixing plate 31 may be aligned with the photovoltaic module, and the driving mechanism 32 and the film-plating mechanism 33 may be oriented towards the photovoltaic module. More specifically, "alignment" means that the length direction of the fixing plate 31 is aligned in parallel with the length direction of the photovoltaic module, the width direction of the fixing plate 31 is aligned in parallel with the width direction of the photovoltaic module, and the projection of the photovoltaic module in the thickness direction thereof is made to fall entirely on the fixing plate 31. It can be understood that after the fixing plate 31 is aligned with the photovoltaic module, the driving mechanism 32 drives the film coating mechanism 33 to move on the fixing plate 31, and the film coating mechanism 33 sprays the film coating liquid onto the surface of the photovoltaic module, so that film supplementing can be performed on the photovoltaic module.

Referring to fig. 1 and 2, the plating mechanism 33 may include a moving plate 331 connected to the driving mechanism 32; a first pipe 332 disposed on the moving plate 331 and capable of communicating with the first liquid storage device 2, and a first perforation 334 may be disposed on the first pipe 332; and a curing lamp 333 provided on the moving plate 331.

In the present embodiment, it is exemplarily illustrated that the shape of the moving plate 331 may be set to be rectangular, and the length and width of the moving plate 331 may be smaller than that of the fixed plate 31. Meanwhile, the length direction of the moving plate 331 may be parallel to the width direction of the fixed plate 31, and the width direction of the moving plate 331 may be parallel to the length direction of the fixed plate 31. It is understood that the moving plate 331 may be driven by the driving mechanism 32 to move on the fixed plate 31, and the moving direction of the moving plate 331 is the length direction of the fixed plate 31. Of course, in some embodiments of the present application, the width direction of the moving plate 331 may be parallel to the width direction of the fixed plate 31, and the length direction of the moving plate 331 may be parallel to the length direction of the fixed plate 31. This enables the position of the moving plate 331 on the fixed plate 31 to be precisely controlled, and thus the target position of the surface of the photovoltaic module to be accurately film-fed. In addition, the moving plate 331 may be provided in other structures, such as a circular plate, a square plate, etc., which are not particularly limited in this application.

Referring to fig. 2, more specifically, the first pipe 332 may be provided as a circular pipe, and the first penetration holes 334 may be provided in plurality in an axial direction of the first pipe 332. The moving plate 331 may be provided with a bracket (not shown) for mounting and fixing the first pipe 332, the bracket may be provided in a shape of a "table", and the bracket and the moving plate 331 may be fixed by means of screws or the like, and the bracket may be provided at both ends of the first pipe 332 to press-fix the first pipe 332 to the moving plate 331. It will be appreciated that the first conduit 332 may move synchronously with the moving plate 331 as the driving mechanism 32 drives the moving plate 331 to move on the fixed plate 31.

Referring to fig. 2 and 3, more specifically, the first pipe 332 and the first liquid storage device 2 may be provided with a first conveying pipe 23 in a communicating manner, and the first conveying pipe 23 may be a hose so as to reasonably design the wiring of the first conveying pipe. The first delivery pipe 23 may be provided with a first liquid outlet pump 24 for pumping the plating film to the first pipe 332, and the first liquid outlet pump 24 may be a diaphragm pump. The first pipe 332 may further be provided with a first valve 25, where the first valve 25 may be a two-way valve, which is used to control the on-off between the first pipe 332 and the first conveying pipe 23.

More specifically, the curing lamp 333 may be provided in a cylindrical shape, which may employ an infrared curing lamp or an ultraviolet curing lamp, and is used to cure the coating liquid to form an antireflection film. The curing lamp 333 may also be fixed to the moving plate 331 by a bracket (not shown), and it is understood that the driving mechanism 32 drives the moving plate 331 to move on the fixed plate 31, and the curing lamp 333 may also move synchronously with the moving plate 331. The curing lamp 333 may be disposed above the first pipe 332, however, in some embodiments of the present application, the curing lamp 333 may be disposed below the first pipe 332, and in any arrangement, the coating mechanism 33 needs to move along the direction of the curing lamp 333 toward the first pipe 332 during coating, so that the curing lamp 333 can immediately cure the coating liquid sprayed from the first through hole 334 of the first pipe 332.

It will be appreciated that when film repair is required for the photovoltaic module, the fixing plate 31 may be aligned with the photovoltaic module, then the film plating solution is pumped out of the first liquid storage device 2 by the first liquid outlet pump 24, then the first valve 25 is opened, then the film plating solution is sent to the first pipeline 332 by the first conveying pipe 23, and then the film plating solution is sprayed out by the first perforation 334. Meanwhile, the movable plate 331 can be driven to move on the fixed plate 31 through the driving mechanism 32, and as the first pipeline 332 and the curing lamp 333 can synchronously move along with the movable plate 331, the coating liquid can be uniformly sprayed on the surface of the photovoltaic module in the moving process of the first pipeline 332, and the curing lamp 333 can cure the coating liquid sprayed on the surface of the photovoltaic module, so that the purpose of film supplementing of the photovoltaic module is achieved. It will be further appreciated that by controlling the pump pressure of the first liquid outlet pump 24, the size and distribution of the aperture of the first perforation 334 can control the liquid outlet amount of the coating liquid, thereby controlling the thickness and uniformity of the antireflection film.

Referring to fig. 4, the first perforation 334 may be a gradually expanding hole, and the size of the gradually expanding hole gradually increases from inside to outside. In this embodiment, the first perforation 334 may be provided as a truncated cone, the small end of which may be near the axis of the first tube 332 and the large end of which may be far from the axis of the first tube 332, for example. The gradually-reaming can guide the coating liquid when the coating liquid is sprayed out, so that the coating liquid is distributed in a wider range and more uniformly, and the thickness uniformity of the anti-reflection film formed after spraying is improved. The cross section of the gradually expanding holes can be round, square or polygonal.

Referring to fig. 2 and 3, the first duct 332 may be parallel to the curing lamps 333. In the present embodiment, it is exemplarily illustrated that the axes of the first duct 332 and the curing lamps 333 may be both parallel to the width direction of the fixing plate 31; also, the length of the first pipe 332 may be equal to the length of the curing lamps 333. Since the moving direction of the moving plate 331 is the length direction of the fixed plate 31, in order to enable the spraying range of the first pipe 332 and the irradiation range of the curing lamp 333 to cover the whole photovoltaic module, in this embodiment, the distance of the first pipe 332 moving along with the moving plate 331 needs to be greater than or equal to the length of the fixed plate 31, and the length of the first pipe 332 needs to be greater than or equal to the width of the fixed plate 31. By the arrangement mode, the irradiation of the curing lamp 333 to the plating solution can be more uniform, and the curing effect of the curing lamp 333 is better.

During the sliding process of the sliding rod 322, the guide rail 321 can guide the sliding rod 322 so as to enable the sliding rod 322 to slide more stably. The sliding rod 322 is fixedly connected with the moving plate 331, so that the moving plate 331 moves synchronously with the sliding rod 322, so as to achieve the purpose of driving the moving plate 331 to move on the fixed plate 31. The end of the slide bar 322 may be provided with an open slot into which the guide rail 321 is inserted so that the slide bar 322 is not easily separated from the guide rail 321 during the movement.

The two ends of the sliding rod 322 may have a larger diameter than the middle portion thereof and are slidably connected to the two guide rails 321, respectively, and the middle portion of the sliding rod 322 may be fixedly connected to the moving plate 331. The two guide rails 321 respectively guide the two ends of the sliding rod 322, so that the stability of the sliding rod 322 in the sliding process can be improved, and further, the moving plate 331 is stable when sliding along with the sliding rod 322, and the uniformity of the film thickness is improved.

It will also be appreciated that by controlling the rotational speed of the drive motor 327, the speed of movement of the first conduit 332 may be controlled, thereby effecting control of the thickness and uniformity of the anti-reflection film.
