[0053] This embodiment provides a coating device that can achieve fully automatic coating of solar panels, improve coating efficiency, and achieve better coating uniformity, thereby improving the coating consistency of solar panels.

[0054] Specifically, such as Figure 1 As shown, the coating apparatus includes a coating platform 100, a positioning mechanism 200, a coating mechanism 400, and a moving mechanism 300. The positioning mechanism 200 is mounted on the coating platform 100 and is used to fix the solar panel 10. The coating mechanism 400 is used to apply a coating liquid to the solar panel 10. The moving mechanism 300 is mounted on the coating platform 100 and connected to the coating mechanism 400. The moving mechanism 300 is used to adjust the distance between the coating mechanism 400 and the solar panel 10, and to drive the coating mechanism 400 to coat the solar panel 10 fixed on the coating platform 100.

[0055] To facilitate understanding, the working process of this coating device will now be briefly described;

[0056] First, the solar cell panel 10 is fixed on the coating platform 100 through the positioning mechanism 200;

[0057] Then, the moving mechanism 300 is started, the distance between the coating mechanism 400 and the solar cell panel 10 is adjusted according to the required coating thickness, after the position of the coating mechanism 400 is adjusted, the distance between the coating mechanism 400 and the solar cell panel 10 is kept unchanged;

[0058] After that, the coating mechanism 400 is driven by the moving mechanism 300 to realize the full-range coating of the solar cell panel 10 according to the set mode.

[0059] The coating device provided in the embodiment can drive the coating mechanism 400 to approach or move away from the coating platform 100 through the moving mechanism 300, which can flexibly set the coating thickness according to the coating requirement and keep the coating thickness, thereby improving the uniformity and consistency of the coating. The movement of the coating mechanism 400 driven by the moving mechanism 300 can realize the full-automatic coating of the solar cell panel 10, and compared with manual coating, the coating efficiency is improved.

[0060] Optionally, continuing to refer to Figure 1 The positioning mechanism 200 comprises a plurality of positioning blocks 210, and the plurality of positioning blocks 210 surround a limiting space for fixing the solar cell panel 10. The solar cell panel 10 is fixed through the positioning blocks 210, which has a simple structure and good fixing effect.

[0061] Further, continuing to refer to Figure 1 In the embodiment, four positioning blocks 210 are arranged, and the four positioning blocks 210 abut against four edges of the solar cell panel 10. In this way, the four edges of the solar cell panel 10 can be limited to ensure the fixing effect of the solar cell panel 10, and too many positioning blocks 210 are not needed.

[0062] In addition, the positioning block 210 is provided with an elongated hole 211, the connecting piece is connected to the coating platform 100 through the elongated hole 211, so as to fix the positioning block 210 on the coating platform 100, and the elongated hole 211 is used to adjust the distance between two positioning blocks 210 arranged oppositely. That is, the elongated hole 211 arranged on the positioning block 210 can realize the connection between the positioning block 210 and the coating platform 100, and can also realize the fine adjustment of the position of the positioning block 210, so that the positioning mechanism 200 can be applied to solar cell panels 10 of different sizes, thereby improving the universality of the coating device.

[0063] Of course, in other embodiments, the number and arrangement mode of the positioning blocks 210 can also be other modes, which can be set according to actual needs, and the application does not make specific limitation.

[0064] Further, as shown in Figure 1 and Figure 2 , the coating device further comprises a base 500 and a rotating mechanism 600. The base 500 is rotatably connected with the first edge of the coating platform 100. The rotating mechanism 600 is arranged on the base 500 and can be fixed or separated from the second edge of the coating platform 100. When the rotating mechanism 600 is fixed with the coating platform 100, the angle between the coating platform 100 and the base 500 is kept unchanged. When the rotating mechanism 600 is separated from the coating platform 100, the coating platform 100 can rotate relative to the base 500. In this way, the coating platform 100 can be arranged horizontally or obliquely. When the solar cell panel 10 is coated, the coating platform 100 can be arranged horizontally to ensure the uniformity of the coating and avoid the downward flow of the coating liquid due to gravity. During the coating process, the coating liquid may fall on the coating platform 100, so the coating platform 100 needs to be cleaned regularly. At this time, the coating platform 100 can be arranged obliquely to make the coating liquid drop under the action of gravity, thereby achieving the cleaning of the coating platform 100. The structure is simple and the cleaning is convenient.

[0065] It should be noted that the coating platform 100 should be cleaned when the coating of the solar cell panel 10 is not needed, so as to avoid the influence of the oblique arrangement of the coating platform 100 on the uniformity of the coating liquid on the solar cell panel 10. Of course, if the uniformity of the coating liquid on the solar cell panel 10 is not high and the thickness of the coating liquid is thin, the coating of the solar cell panel 10 can be carried out when the coating platform 100 is obliquely arranged, so that the coating and the cleaning of the coating platform 100 can be carried out simultaneously. The specific arrangement can be set according to the actual needs.

[0066] Optionally, continuing to refer to Figure 2 In this embodiment, the rotating mechanism 600 comprises an angle adjusting plate 610 and an adjusting bolt 620. One end of the angle adjusting plate 610 is connected with the base 500, and an arc-shaped adjusting hole 611 is arranged on the other end of the angle adjusting plate 610. The adjusting bolt 620 is connected with the threaded hole on the second edge of the coating platform 100 through the arc-shaped adjusting hole 611.

[0067] Specifically, the use method of the rotating mechanism 600 is as follows:

[0068] First, loosen the adjusting bolt 620 so that the coating platform 100 can rotate; then manually rotate the coating platform 100 to the desired position; finally, tighten the adjusting bolt 620 so that the head of the adjusting bolt 620 tightly abuts against the angle adjusting plate 610 to fix the coating platform 100 at the position.

[0069] The rotating mechanism 600 can realize the angle adjustment of the coating platform 100 by rotating the adjusting bolt 620, and has simple structure and convenient adjustment.

[0070] Optionally, two rotating mechanisms 600 can be arranged, and the two rotating mechanisms 600 can be arranged at the second edge and the third edge of the coating platform 100 respectively, wherein the second edge and the third edge are adjacent to the first edge. In this way, the force uniformity of the coating platform 100 can be improved, and the reliability of the angle adjustment is improved.

[0071] Further, referring to Figure 1 , the base 500 is provided below with a liquid collecting groove 700, and the liquid collecting groove 700 is used for collecting the liquid dripping on the coating platform 100. By arranging the liquid collecting groove 700, the liquid cleaned can be collected and recycled, and the cleanliness of the surrounding environment can be maintained.

[0072] Further, as shown in Figures 3-5 , the coating mechanism 400 comprises a feeding member 410, a liquid suction member 420 and a coating cloth 430. The feeding member 410 is provided with a feeding cavity, and the feeding member 410 is provided with a feeding port 411 and a discharging port 413 which are in communication with the feeding cavity. The discharging port 413 is arranged at the bottom of the feeding member 410, and the liquid suction member 420 is arranged at the bottom of the feeding member 410. One side of the liquid suction member 420 is attached to the discharging port 413 to adsorb the liquid flowing out of the discharging port 413. The coating cloth 430 is wrapped outside the liquid suction member 420, and the two ends of the coating cloth 430 are connected to the opposite sides of the feeding member 410. The liquid in the liquid suction member 420 can penetrate onto the coating cloth 430, and finally the liquid is coated onto the solar cell panel 10 by the coating cloth 430.

[0073] Optionally, the feeding member 410 is further provided with an air inlet 412 which is in communication with the feeding cavity, so that the gas with different pressures can be input into the feeding cavity through the air inlet 412, and the quantitative discharging of the feeding member 410 can be realized.

[0074] Specifically, the working principle of the coating mechanism 400 is as follows:

[0075] The liquid conveying device conveys the liquid into the feeding cavity through the feeding port 411, and the compressed gas conveying device conveys the gas with a certain pressure into the feeding cavity through the air inlet 412, so that the liquid in the feeding cavity can be conveyed onto the liquid suction member 420 at a specific speed. The liquid adsorbed on the liquid suction member 420 finally penetrates onto the coating cloth 430, and the solar cell panel 10 is coated by the coating cloth 430.

[0076] The coating mechanism 400 can directly brush the material liquid on the solar cell panel 10 in the coating process through the action of the coating cloth 430 and the material suction member 420, compared with the coating mode in the prior art that the material liquid is first discharged and then the material liquid is scraped, the process of discharging the material liquid and scraping the material liquid is combined into one process, which simplifies the structure of the coating mechanism 400 and saves the process. Moreover, the material suction member 420 has a certain elastic deformation capacity, and reliable coating can be realized for the solar cell panel 10 with a certain deformation amount, and the risk of leakage is low.

[0077] It should be noted that the compressed gas conveying device can be provided with a pressure regulating valve to adjust the inlet pressure of the gas inlet 412 to realize the adjustment of the liquid supply speed.

[0079] Optionally, continuing to refer to Figure 5 , the discharge port 413 can be provided with multiple discharge ports 413, and the multiple discharge ports 413 can be arranged at intervals along the length direction of the material feeding cavity to increase the contact area between the discharge port 413 and the material suction member 420 and improve the liquid supply efficiency.

[0080] Optionally, in the embodiment, the material feeding member 410 is connected with the moving mechanism 300.

[0081] Further, continuing to refer to Figure 3 and Figure 4 , the coating mechanism 400 further comprises a coating cloth fixing assembly 440 corresponding to both ends of the coating cloth 430, and the coating cloth fixing assembly 440 is used to connect the end of the coating cloth 430 with the material feeding member 410. Specifically, the coating cloth fixing assembly 440 comprises a pressing block 441 and a fastener 442, the pressing block 441 abuts and presses the end of the coating cloth 430 on the material feeding member 410, and the fastener 442 is arranged through the pressing block 441 and the end of the coating cloth 430 and connected with the material feeding member 410. The coating cloth fixing assembly 440 has a simple structure and good fixing effect on the coating cloth 430.

[0082] Optionally, the fastener 442 can be provided with one or multiple fasteners 442, which can be set according to actual needs, and multiple fasteners 442 can improve the fixing effect on the coating cloth 430. In the embodiment, the fastener 442 is provided with two fasteners.

[0083] Further, continuing to refer to Figure 4 and Figure 5The opposite sides of the feeding piece 410 are provided with mounting plates 450, the two mounting plates 450 and the feeding piece 410 form a mounting cavity with an opening 452 in the bottom, the mounting cavity is used for mounting the material suction piece 420, the bottom of the material suction piece 420 extends out of the opening 452, and the coating cloth 430 is wrapped outside the two mounting plates 450 and the material suction piece 420 extending out of the opening 452. By arranging the mounting plates 450, only the bottom of the material suction piece 420 extending out of the opening is in contact with the coating cloth 430, the feeding of the coating cloth 430 is realized, the side of the material suction piece 420 does not need to feed the side of the coating cloth 430 which does not need to be in contact with the solar cell panel 10, and then the waste of the material liquid can be avoided, and the precise feeding can be realized.
