[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1:

[0042] As Figures 1 to 11As shown in the figure, the present invention provides a coating device for a glass mirror used in solar power generation. The coating device includes a circulating conveyor 1, a clamping structure 2, a mounting frame 3, a loading device 4, a coating structure 5, a detection mechanism 6, and a unloading device 8. Among them, the circulating conveyor 1 is used to circulate and convey the equipment; several clamping structures 2 are evenly distributed at the working end of the circulating conveyor 1, and the clamping structures 2 are arranged vertically; the mounting frame 3 is arranged below the clamping structure 2, and the glass mirror is detachably arranged in the mounting frame 3; the loading device 4 is arranged on one side of the circulating conveyor 1, and the working end of the loading device 4 is arranged opposite to the working end of the clamping structure 2; the coating structure 5 is arranged on the side of the circulating conveyor 1 away from the loading device 4, and the coating structure 5 includes a cleaning component and a coating component; the detection mechanism 6 is arranged on the same side in front of the loading device 4, and the detection mechanism 6 includes a light source, a detection plate 7, and an adjustment structure; the unloading device 8 is arranged between the detection mechanism 6 and the loading device 4 and on the same side, and the unloading device 8 has the same structure as the loading device 4, and the working end of the unloading device 8 is arranged opposite to the working end of the clamping structure 2.

[0043] Therefore, in the process of specific implementation of this embodiment, the loading device 4 transports the mounting frame 3 with the glass mirror to the side of the clamping structure 2, and then the clamping structure 2 clamps it. The circulating conveyor 1 rotates counterclockwise. After the cleaning component finishes cleaning, coating is carried out, making the whole process perfect, realizing smooth continuous operation, improving the degree of automation, and eliminating the need for additional cleaning equipment before loading. The cleaning process is integrated into the coating step to prevent affecting production efficiency. Moreover, the cleaning effect of the cleaning component is good, and it can clean the dust and impurities on the glass mirror to prevent affecting the coating effect.

[0044] At the same time, this embodiment also uses the detection mechanism 6 to detect the coated glass mirror, so as to know the coating quality before unloading, facilitating subsequent processing. Moreover, the irradiation angle of the light source on the glass mirror is adjusted through the adjustment structure, and the detection plate 7 conducts multiple detections of the irradiated light to improve the detection accuracy and prevent defective products from not being detected.

[0045] Embodiment Two:

[0046] In order to further clearly and completely elaborate on the clamping structure 2 in the above Embodiment One, the present invention also provides Embodiment Two, as Figures 1 to 4As shown in the figure, in the second embodiment, the clamping structure 2 includes a telescopic cylinder 9, which is fixedly connected to the lower end of the working end of the circulating conveyor 1. The lower end of the telescopic cylinder 9 is fixedly connected to a box body 10 with an opening at the bottom. The upper end of the inner wall of the box body 10 is fixedly connected to a telescopic cylinder 11. On both sides below the telescopic cylinder 11, there are clamping rods 12. The two clamping rods 12 are symmetrically arranged. At the lower part of the adjacent ends of the two clamping rods 12, there are fixedly connected friction parts. The telescopic cylinder 11 is connected between the two clamping rods 12 through an inclined rotating rod 13 by means of a hinge. The upper ends of the two rotating rods 13 are close to each other and the lower ends are separated from each other. A chute 14 is opened at the lower part of the inner wall of the box body 10, and the clamping rod 12 is slidably connected in the chute 14.

[0047] Therefore, in the specific implementation of the second embodiment, the circulating conveyor 1 stops conveying. The telescopic cylinder 9 first contracts upward to leave enough space for loading. The loading device 4 adsorbs and moves the mounting frame 3 with the glass mirror installed to the lower part of the corresponding box body 10. The lower end of the telescopic cylinder 9 extends downward. At the same time, the telescopic cylinder 11 contracts upward, pulling the lower parts of the two clamping rods 12 to rotate towards the adjacent ends. Under the guiding action of the chute 14, the two clamping rods 12 slide towards the adjacent ends to clamp and fix the upper part of the mounting frame 3. Then, the circulating conveyor 1 drives the clamping structure 2 to rotate counterclockwise for the coating step.

[0048] Embodiment Three:

[0049] In order to further clearly and completely elaborate on the coating structure 5 in the first embodiment above, the present invention also provides Embodiment Three. As shown in Figure 2 、 Figure 5 , in the third embodiment, the coating structure 5 further includes a process block 15. The cleaning component includes a water draining groove 16 and a cleaning groove 17 opened at the upper end of the process block 15. The coating component includes a coating groove 18 and a water draining groove 19 opened at the upper end of the process block 15. The cleaning groove 17, the water draining groove 16, the coating groove 18, and the water draining groove 19 are distributed in sequence from the back to the front, and the cross-sectional area ratio is 1:2:1:1. During the circulating conveying process of the circulating conveyor 1, the residence time for each step is the same.

[0050] Specifically, the cleaning component further includes a gas delivery pump 20 arranged at the rear of the outside of the cleaning groove 17. The front part of the gas delivery pump 20 is fixedly connected to a connecting pipe 21. The front end of the connecting pipe 21 passes through the process block 15 and extends into the cleaning groove 17. A plurality of uniformly distributed distribution pipes 22 are arranged on the lower side inside the cleaning groove 17. The distribution pipes 22 are all communicated with the connecting pipe 21. A plurality of uniformly distributed air outlet pipes 23 are opened at the upper ends of the distribution pipes 22. The air outlet pipes 23 are communicated with the distribution pipes 22. The bottom of the cleaning groove 17 is fixedly connected with a plurality of brackets 24 for fixing and supporting the distribution pipes 22, so that the distribution pipes 22 do not contact the bottom of the cleaning groove 17 and form a certain distance, which can ensure the flow of water at the bottom.

[0051] Therefore, during the specific implementation of this embodiment, when the clamping structure 2 passes above the cleaning tank 17, the circulating conveyor 1 stops conveying, the lower end of the first telescopic cylinder 9 extends downward, and the mounting frame 3 enters the cleaning tank 17. The cleaning tank 17 is filled with water containing a cleaning solution. The mounting frame 3 is completely immersed in the water. The gas delivery pump 20 delivers compressed gas to the connecting pipe 21 and then to each distribution pipe 22, and is delivered to the cleaning tank 17 through the air outlet pipe 23. The compressed gas sprays upward from the bottom, disturbing the water in the cleaning tank 17. The disturbance of the water flow is used to clean the glass mirror, disturbing the dust and impurities on it to achieve the purpose of cleaning.

[0052] Embodiment 4:

[0053] Based on the cleaning mechanism in Embodiment 3, after cleaning, it is necessary to further rinse the water containing the cleaning solution to prevent it from affecting the coating. Therefore, Embodiment 4 is proposed. As Figure 2 、 Figure 5 、 Figure 7 , in this Embodiment 4, a water storage cavity 25 is arranged in the process block 15 below the first drain tank 16. Spraying plates 26 with hollow interiors are fixedly connected to the upper parts on both sides of the rear of the first drain tank 16. Nozzles communicating with their interiors are fixedly connected to the adjacent ends of the two spraying plates 26. Water pumps 27 connected to the water storage cavity 25 are fixedly connected to both sides of the process block 15. Water pipes 28 are fixedly connected between the two water pumps 27 and the two spraying plates 26. An inlet pipe is arranged at the upper part of one side of the water storage cavity 25 away from the circulating conveyor 1. An outlet pipe 1 is arranged at one side of the lower part of the first drain tank 16 close to the inlet pipe. The inlet pipe 1 and the outlet pipe are both fixedly connected to the process block 15. Heating and drying machines 1 29 are fixedly connected to the upper parts on both sides of the front of the first drain tank 16. A heating part 30 is arranged at the lower end of the inner wall of the coating tank 18. Heating and drying machines 2 31 are fixedly connected to the upper parts on both sides of the second drain tank 19. An outlet pipe 2 fixedly connected to the process block 15 is arranged at one side of the second drain tank 19 close to the inlet pipe. The inlet pipe 1, the outlet pipe 1, and the outlet pipe 2 are all provided with sealing covers. Preferably, a sealing cover (not shown in the figure) is arranged above the coating tank 18, the heating and drying machine 1 29, and the heating and drying machine 2 31, and is connected to the waste gas treatment device through a pipeline. The organic solvents (such as coating solution diluents) volatilized during the coating process and the hot steam generated during drying are collected through the pipeline and centrally treated.

[0054] Therefore, when the present embodiment is specifically implemented, the loop conveyor 1 drives the installation frame 3 after cleaning to continue moving. When it moves between the two spraying plates 26, the water pump 27 extracts the clear water in the water storage cavity 25 and transports it through the water pipe 28 to the spraying plate 26, and sprays it out from the nozzles to wash the installation frame 3 and the glass mirror installed therein, cleaning the remaining cleaning liquid. After cleaning, the loop conveyor 1 continues to transport. The installation frame 3 moves between the two first heating and drying machines 29, and the two first heating and drying machines 29 dry the installation frame 3 and the glass mirror. The first drain tank 16 is used to receive the remaining cleaning liquid and the clear water generated by spraying to prevent environmental pollution. Then, the clamping structure 2 drives the installation frame 3 to continue moving, coats the film in the coating tank 18, and then moves between the two second heating and drying machines 31 for drying. The process is centralized, the degree of automation is improved, and the production efficiency can also be improved.

[0055] Embodiment Five:

[0056] In order to further clearly and completely describe the detection mechanism 6 in the above Embodiment One, the present invention also provides Embodiment Five, as Figure 1 , Figures 8 to 11 shown in, in this Embodiment Five, the detection mechanism 6 further includes a workbench 32 disposed below the clamping structure 2. Both sides of the upper end of the workbench 32 are fixedly connected with vertical plates 33. The light source and the detection plate 7 are respectively disposed on the adjacent sides of the two vertical plates 33. The light source includes a light emitting part 34. A central light source 35 is disposed in the middle of the side of the light emitting part 34 close to the detection plate 7. A plurality of uniformly distributed peripheral light sources 36 are disposed on the periphery of the central light source 35. One side of the upper part of the workbench 32 is fixedly connected with a processor 46 electrically connected to the detection plate 7.

[0057] Further, a mounting plate 37 is fixedly connected to the side of the light emitting part 34 away from the detection plate 7. A rotating block 38 is fixedly connected to the side of the mounting plate 37 away from the light emitting part 34. The side of the rotating block 38 away from the mounting plate 37 is hinged to a fixed rod 39 fixedly connected to the vertical plate 33. A slide rail 40 is fixedly connected to the lower end of the mounting plate 37. The slide rail 40 is open towards the side away from the light emitting part 34. A slider 41 is slidably connected in the slide rail 40. The side of the slider 41 away from the light emitting part 34 is hinged to a telescopic cylinder three 42 fixedly connected to the vertical plate 33.

[0058] Therefore, when this embodiment is specifically implemented, the central light source 35 projects onto the surface of the glass mirror, passes through the surface of the glass mirror, and reaches the detection plate 7. The detection plate 7 receives the light signal and sends the light signal into the processor 46. The processor 46 determines whether the coating of the glass mirror is qualified by calculating the light transmittance. Then, the peripheral light source 36 projects light onto the glass mirror surface, passes through the glass mirror surface, and reaches the detection plate 7. The detection plate 7 sends the projection contour to the processor 46. The processor 46 determines whether the coating of the glass mirror is qualified according to the projection contour. Then, for further detection, when the telescopic cylinder three 42 extends, it pushes the slider 41 to slide downward in the slide rail 40, and the rotating block 38 drives the light source to rotate upward through the mounting plate 37. When the telescopic cylinder three 42 contracts, it pulls the slider 41 to slide upward in the slide rail 40, and the rotating block 38 drives the light source to rotate downward through the mounting plate 37, so that the light source performs pitch adjustment. This embodiment uses the light sources at five angles (-60°, -30°, 0°, 30°, 60°) for testing. Through testing at multiple angles, the test accuracy can be further improved. The central light source 35 and the peripheral light source 36 do not irradiate simultaneously.

[0059] Embodiment Six:

[0060] Based on Embodiment Five, after the glass mirror is coated, it is detected. To facilitate the subsequent identification of defective products, the present invention also provides Embodiment Six. As Figure 1 , Figures 8 to 11 shown in, in this Embodiment Six, telescopic cylinders four 43 are arranged on both sides of the light-emitting part 34. The telescopic cylinders four 43 are fixedly connected to the vertical plate 33 on the side close to the light-emitting part 34. The ends of the front and rear telescopic cylinders four 43 close to the detection plate 7 are respectively fixedly connected with a marking part one 44 and a marking part two 45. The distance between the marking part one 44 and the marking part two 45 matches the distance between the front and rear parts on one side of the mounting frame 3. The marking part one 44 and the marking part two 45 can respectively mark defective products and qualified products. After the detection is completed, while the processor 46 retains the detection result, it controls the telescopic cylinders four 43 on both sides to extend according to the result. For example, if the detection is qualified, the front telescopic cylinder four 43 extends, and the marking part one 44 follows and contacts the front part on the side of the mounting frame 3 close to the light source, and then leaves a qualified mark. On the contrary, the marking part two 45 leaves an unqualified mark for subsequent processing.

[0061] In summary, the coating equipment for a glass mirror used in solar power generation provided by the present invention at least has the following advantages:

[0062] By cleaning impurities and dust from the glass mirror in the cleaning tank 17, rinsing and drying in the water draining tank one 16, then coating in the coating tank 18, and drying again in the water draining tank two 19, the process is centralized, continuous operation is realized, the degree of automation is improved, and the production efficiency can also be improved.

[0063] The compressed gas is sent into the distribution pipe 22 by the gas delivery pump 20 of the cleaning component. The compressed gas ejects upward from the bottom, disturbing the water in the cleaning tank 17. The disturbance of the water flow is used to clean the glass mirror, disturbing the dust and impurities on it to achieve the purpose of cleaning.

[0064] After the coating is completed, the central light source 35 and the peripheral light source 36 are respectively projected onto the surface of the glass mirror (not simultaneously), and reach the detection board 7 after passing through the surface of the glass mirror. The processor 46 determines whether the coating of the glass mirror is qualified to achieve the purpose of timely detection, and then adjusts the pitch of the light source. Through tests at multiple angles, the test accuracy can be further improved.

[0065] It should be noted here that the electrical components mentioned in this article are all electrically connected to the external main controller and the 220V mains power. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific embodiments of the present disclosure. To ensure the compatibility of the device, the operation means adopted are consistent with the parameters of market instruments.

[0066] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the spirit of the present invention, they shall fall within the protection scope of the present invention.
