Description of the embodiments
For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings. Wherein like parts are designated by like reference numerals.
In view of the defects of the prior art mentioned in the background art, the utility model provides an online drawing and coating device for a photovoltaic frame, which is used for being arranged in a drawing and extruding production line of the photovoltaic frame and carrying out online drawing and coating treatment on the drawn and extruded photovoltaic frame.
Fig. 1 is a schematic perspective view of a photovoltaic frame of an on-line dip coating device according to the present utility model, and fig. 2 is a schematic cross-sectional view of the photovoltaic frame shown in fig. 1. Of course, the utility model is not limited to this shape and configuration of light Fu Biankuang, and the principles of the draw-coating device of the utility model are described herein by way of example only.
The photovoltaic border 1 shown in fig. 1-2 may be made of metal, such as an aluminum alloy, or may be made of a non-metallic composite material, such as a fiberglass-doped polyurethane plastic, or may be made of other metallic or non-metallic materials known in the art.
The illustrated photovoltaic frame 1 comprises a mounting slot 11 for mounting a photovoltaic module (not shown), a rectangular cavity 12 is arranged below the mounting slot 11, and a flange 13 is formed at the bottom of the cavity 12 to increase the width of the bottom of the cavity 12 through the extended flange 13, so as to improve the bottom mounting surface and structural strength of the photovoltaic frame 1, and facilitate mounting on a photovoltaic bracket (not shown).
The cross section shape of the photovoltaic frame 1 is kept unchanged along the length direction, and the photovoltaic frame is suitable for production by means of pultrusion, and is particularly suitable for production molding of photovoltaic frames made of nonmetal materials such as plastics, composite materials and the like.
As described in the background art, the surface spraying process is adopted to carry out surface treatment on the photovoltaic frame, the utilization rate of the water-based paint is low, and the volatile solvent adopted by spraying can bring environmental protection problems, so that the online dip coating process is adopted, an online dip coating device can be combined with a pultrusion production line (not shown in the figure), the production efficiency and the utilization rate of the water-based paint are improved, the surrounding environment is not polluted, the surface of a paint film of a finished product is uniform, and the effect is excellent.
In particular, the photovoltaic frame online drawing and coating device is shown in fig. 3-6, is arranged in a drawing and extruding production line along the drawing direction shown by an arrow in the drawing and extruding production line, for example, is arranged between a die outlet and a tractor of the drawing and extruding production line, and comprises an online coating mechanism 2 and a drying mechanism 3 which are arranged along the drawing and extruding direction of the photovoltaic frame 1. The on-line coating mechanism 2 and the drying mechanism 3 may be fixedly disposed above a supporting cabinet 5. The supporting cabinet 5 is used for lifting the on-line coating mechanism 2 and the drying mechanism 3 so as to enable the height of the on-line coating mechanism to be matched with that of a pultrusion production line. The space below the supporting cabinet 5 can be used for placing paint cans (not shown) and the like.
Further, as shown in the figure, the on-line coating mechanism 2 comprises a box 21, an elastic coating body 22, a roller coating mechanism 23 and a scraping plate 24 are sequentially arranged in the box 21 along the drawing direction of the photovoltaic frame 1, and a material recovery mechanism 25 is arranged below the roller coating mechanism 23 and the scraping plate 24. In fig. 4, for clarity of illustration, the upper half of the case 21 is not shown, and a part of the roll coating mechanism 23 is also cut away. The outer structure of the rear half of the case 21 in fig. 5 is removed, and in addition, a portion of the structure of the photovoltaic frame 1 located in the case 21 is removed not shown to expose a portion of the structure shielded by the photovoltaic frame 1.
The elastic coating body 22 is an elastic rectangular parallelepiped fixed inside the case 21, and may be made of a porous elastic material such as sponge, for example, and filled inside the case 21. The center of the elastic coating body 22 is provided with a hole for the photovoltaic frame 1 to pass through, the hole is smaller than the outline dimension of the photovoltaic frame 1, and the photovoltaic frame 1 passes through the hole through extrusion. In order to avoid the photovoltaic frame 1 from pulling the elastic coating body 22 away, a baffle 221 with an opening may be provided at the rear end of the elastic coating body 22 to fix the elastic coating body 22 inside the case 21.
The case 21 is provided with a material injection pipe 221 for feeding paint to the elastic coating body 22, and the material injection pipe 221 is provided on four sides of the case 21. The filling pipe 221 may be connected to a paint delivery pump or the like for uniformly delivering paint to the periphery of the elastic coating body 22 by pressure so that the elastic coating body 22 is impregnated with paint as a whole. When the photovoltaic frame 1 is pressed through the hole inside the elastic coating body 22, the coating material impregnated in the elastic coating body 22 is also transferred and attached to the outer surface of the photovoltaic frame 1. The coating used may be a black aqueous tetrafluorocarbon paint, or other suitable polyurethane coating. The mould cavity 12 of the photovoltaic frame 1 is sealed after assembly and no surface treatment is required.
The paint on the outer surface of the photovoltaic frame 1 drawn out from the elastic paint body 22 may form stripes in the longitudinal direction, and there may be some cases where the paint is uneven, so the present utility model is provided with a roll coating mechanism 23 at the rear end of the elastic paint body 22. As shown in particular, the roll coating mechanism 23 includes a plurality of elastic coating rollers 231 fixed inside the case 21, and the elastic coating rollers 231 are disposed around the periphery of the photovoltaic frame 1 and are rotatably pressed into contact with the outer side wall of the photovoltaic frame 1. For example, four elastic coating rollers 231 may be provided around the periphery of the photovoltaic frame 1, and the four elastic coating rollers 231 may be installed at the side of one support plate with an opening. The elastic paint roller 231 may uniformly paint the outer surface of the photovoltaic frame 1 in a roll coating manner. Of course, it can be seen from the structure of the photovoltaic frame 1 that the elastic paint roller 231 can be used only to roller paint the outer surface of the photovoltaic frame 1, and cannot reach the inside of the mounting notch 11. The mounting notch 11 is filled with sealant at the time of mounting the photovoltaic module, so that the inside of the mounting notch 11 does not actually require strict surface treatment, and it is sufficient to perform the suction coating treatment of the elastic coating body 22. The size and number of the elastic coating rollers 231 may be adjusted and arranged according to the shape of the sample, and are not limited to four or the illustrated arrangement.
The external surface of the photovoltaic frame 1 after being treated by the roller coating mechanism 23 may have a problem of too large thickness of the coating, so the utility model is provided with a scraping plate 24 at the rear end of the roller coating mechanism 23. Specifically, as shown in the figure, the scraping plate 24 is fixedly connected with the inner side wall of the box body 21, and the scraping plate 24 is provided with a hanging hole 241 matched with the outline dimension of the photovoltaic frame 1. After scraping, the thickness of the paint film on the surface of the photovoltaic frame is controlled to be 30 (+ -5) micrometers.
In addition, after roll coating and scraping, excessive paint can drip down, and the utility model is further provided with a material recovery mechanism 25. As shown in the drawings, the material recovery mechanism 25 includes a first recovery funnel and a second recovery funnel which are respectively disposed below the roll coating mechanism 23 and the scraper 24, and the first recovery funnel and the second recovery funnel have a common recovery pipe. The recovery pipeline stretches into the inside of the supporting cabinet body 5 downwards, and the recovered paint can be collected into a paint tank arranged in the supporting cabinet body 5 for recycling.
The coated photovoltaic frame 1 is dried by a drying mechanism 3 and then cut. Wherein, drying mechanism 3 includes an inner shell 31 and an outer shell 32, and inner shell 31 hangs in the inside of outer shell 32, and photovoltaic frame 1 passes from inner shell 31, is provided with electric heating mechanism 33 between inner shell 31 and the outer shell 32. For example, the electric heating mechanism 33 may be a U-shaped silicon molybdenum heating rod. Fig. 6 shows a part of the structure of the outer case 32 in a cutaway for clarity of illustration.
To conserve energy and prevent operator scalding, a blanket of insulation may be provided on the inside wall of the outer housing 32. For example, the insulation blanket may be an aerogel insulation blanket.
In addition, the photovoltaic frame on-line drawing and coating device can be further provided with a temperature control mechanism 4 (fig. 3) for controlling the internal temperature of the drying mechanism 3, and the temperature control mechanism 4 is respectively connected with an electric heating mechanism 33 and a thermocouple 34 arranged in the drying mechanism 3. The temperature control mechanism 4 can control parameters such as voltage and current of the electric heating mechanism 33 through the internal temperature measured by the thermocouple 34, so that the temperature can be accurately controlled to obtain the optimal drying effect. For example, after the coating is completed, the photovoltaic frame 1 enters a drying mechanism 3, the temperature in the inner shell 31 is kept at 80 (+ -2) DEG C, and the tetrafluoro-carbon paint on the frame surface is cured through the drying effect.
The photovoltaic frame after drying and cutting is a finished product which is coated and can be used for further assembling with a photovoltaic module.
In summary, compared with the existing spraying technology, the photovoltaic frame online dip coating device improves the utilization rate and the coating efficiency of the coating, and saves the labor cost and the time cost.
