It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0034] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] Please refer to Figures 1-3 An embodiment of this utility model provides a coating uniform coating device for photovoltaic glass, comprising:
[0036] Workbench 1;
[0037] Support 2, a number of supports 1 are provided at equal intervals along the first direction on the top surface of the workbench 1;
[0038] The moving mechanism 3 is movably disposed on the top surface of the workbench 1 along the first direction, located above the support 2;
[0039] The feeding mechanism 4 is fixedly installed on the top of the moving mechanism 3;
[0040] The nozzles 5 are arranged at equal intervals along the second direction, and each nozzle 5 is connected to the feeding mechanism 4. The second direction is perpendicular to the first direction.
[0041] The adjustment mechanism 6 is mounted on the moving mechanism 3 and is connected to several nozzles 5 for adjusting the spacing between each nozzle 5 and maintaining the equal spacing between each nozzle 5.
[0042] The coating mechanism 7, with adjustable coating thickness and angle, is mounted on the moving mechanism 3 and located on one side below each nozzle 5.
[0043] In this embodiment, when coating the photovoltaic glass 8, the spacing between each nozzle 5 is first adjusted according to its specifications by the adjustment mechanism 6 to ensure that the coating sprayed by each nozzle 5 fully covers the photovoltaic glass 8. The spacing between each nozzle 5 remains consistent after adjustment, which has good adaptability and ensures uniform coating. Then, the coating thickness and angle are adjusted according to the coating requirements by the coating mechanism 7 to ensure that the coating thickness meets the design requirements.
[0044] Then, each photovoltaic glass 8 is placed on the support 2 one by one. The moving mechanism 3 drives the spray head 5 in front and the scraping mechanism 7 behind to pass over each photovoltaic glass 8, spraying the coating onto the photovoltaic glass 8 and scraping it flat. The coating is evenly distributed and of consistent thickness, ensuring the processing quality of the photovoltaic glass.
[0045] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the top surface of the support 2 is fixedly provided with an anti-slip pad layer 21 to prevent the photovoltaic glass 8 from slipping and to protect it.
[0046] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the moving mechanism 3 includes linear modules 31 symmetrically arranged on both sides of several supports 2. The top of the linear modules 31 is connected to a moving plate 32, and a moving frame 33 is fixedly arranged above the two moving plates 32.
[0047] In this embodiment, the feeding mechanism 4, the nozzle 5, the adjusting mechanism 6, and the coating mechanism 7 are all mounted on the moving frame 33. The moving frame 33 is driven to move by two sets of linear modules 31, thereby driving the nozzle 5 and the coating mechanism 7 to pass over the photovoltaic glass 8 and complete the coating process, resulting in high processing efficiency.
[0048] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, the feeding mechanism 4 includes a paint tank 41 fixedly installed on the top of the moving mechanism 3. The paint tank 41 is connected to a material pump. The output end of the material pump is connected to a discharge pipe 42. A control valve 43 is installed on the discharge pipe 42. The bottom end of the discharge pipe 42 is connected to a dispensing pipe 44. Each nozzle 5 is connected to the dispensing pipe 44 through a hose 45.
[0049] In this embodiment, the control valve 43 is opened and the material pump is started. The paint enters the dispensing pipe 44 through the discharge pipe 42, and then is delivered to the nozzle 5 through each hose 45. The paint is then sprayed out by the nozzle 5 to complete the coating, ensuring the uniformity of the paint coating.
[0050] In a preferred embodiment, such as Figure 2 and Figure 3As shown, the adjustment mechanism 6 includes a support plate 61 fixedly mounted on the moving mechanism 3. A groove is formed on the bottom surface of the support plate 61 along the second direction. An adjustment rod 62 is arranged parallel to the bottom of the groove. The two ends of the adjustment rod 62 are rotatably connected to the moving mechanism 3. A drive motor 63 is provided on the moving mechanism 3 to drive the adjustment rod 62 to rotate. First threaded sections 64 with opposite threads are symmetrically arranged on both sides of the middle part of the adjustment rod 62. Second threaded sections 65 with the same thread direction are arranged on the outer side of the first threaded sections 64. A first adjustment block 66 is threadedly sleeved on the first threaded section 64, and a second adjustment block 67 is threadedly sleeved on the second threaded section 65. The tops of the first adjustment block 66 and the second adjustment block 67 are slidably connected to the groove. When the adjustment rod 62 rotates, the distance that the second adjustment block 67 moves is twice the distance that the first adjustment block 66 moves. Spray nozzles 52 are fixedly mounted on the bottom of the first adjustment block 66 and the second adjustment block 67, respectively.
[0051] In this embodiment, the adjustment rod 62 is driven to rotate by the drive motor 63, and the first adjustment block 66 and the second adjustment block 67 move along the slide groove respectively. The pitch of the first threaded section 64 and the second threaded section 65 is different, so that if the first adjustment block 66 moves 1cm, the second adjustment block 67 moves 2cm. The spacing between each adjustment block is always kept consistent, ensuring uniform material distribution.
[0052] In some embodiments, when the number of nozzles 52 is odd, a fixed block that is fixedly connected to the support plate 61 is rotatably sleeved at the middle of the adjusting rod 62 via a bearing. When the nozzles 5 below the other adjusting blocks move, the nozzles 5 below the fixed block always remain stationary.
[0053] In other embodiments, when the size of the photovoltaic glass 8 is large and the number of nozzles 5 in this embodiment cannot meet the requirements, the number of threaded sections can be increased, and more adjusting blocks and nozzles 5 can be installed. The pitch is designed so that the moving distance of the adjusting block is twice the moving distance of its inner adjacent adjusting block.
[0054] In a preferred embodiment, such as Figure 1 As shown, a first limiting ring 68 is fixedly installed on the adjusting rod 62 between the two first threaded sections 64, a second limiting ring 69 is fixedly installed between the first threaded section 64 and the second threaded section 65, and a third limiting ring 610 is fixedly installed at the end of the second threaded section 65 away from the first threaded section 64.
[0055] In this embodiment, the movement of the adjusting block within the corresponding threaded segment is limited by a limiting ring to prevent the adjusting block from moving to a mismatched threaded segment and causing an accident, thus ensuring the structural safety of the equipment.
[0056] In a preferred embodiment, such as Figure 1 and Figure 3As shown, the bottom of the first adjusting block 66 and the second adjusting block 67 are both fixedly provided with a transfer pipe 51. The bottom end of the transfer pipe 51 is threadedly connected to the nozzle 5. A flow regulating valve 52 is provided between the transfer pipe 51 and the nozzle 5. A feed pipe 53 is connected to the side wall of the transfer pipe 51. The hose 45 is connected to the nozzle 5 through the feed pipe 53.
[0057] In this embodiment, when the spacing of the nozzles 5 is changed by adjustment, the spraying flow rate of the paint is adjusted by the flow regulating valve 52 to adapt to the change in the spacing of the nozzles 5, avoid the problem of insufficient or excessive paint, and ensure the uniformity of paint application.
[0058] In a preferred embodiment, such as Figures 1-3 As shown, the scraping mechanism 7 includes a shaft 71 arranged along the second direction. Both ends of the shaft 71 are rotatably connected to the moving mechanism 3 via bearings. Electric telescopic rods 72 are symmetrically arranged at both ends of the shaft 71. One end of the electric telescopic rod 72 is rotatably connected to the moving mechanism 3, and the other end is rotatably connected to a transmission rod 73. The end of the transmission rod 73 away from the electric telescopic rod 72 is vertically fixedly connected to the shaft 71. A mounting strip 74 parallel to the shaft 71 is arranged on the side of the shaft 71 away from the nozzle 5. The side of the mounting strip 74 away from the shaft 71 is inclined downward and fixedly connected to a scraper 75. The other side is fixedly connected to the shaft 71 via a connecting rod 76.
[0059] In this embodiment, the electric telescopic rod 72 is controlled to extend and retract. The electric telescopic rod 72 drives the shaft 71 to rotate through the transmission rod 73. The shaft 71 drives the mounting strip 74 to swing through the connecting rod 76, thereby adjusting the angle of the scraper 75, thus realizing the adjustment of the coating thickness and ensuring the quality of coating.
