Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic glass processing and cleaning equipment, and in particular to a cleaning equipment and system for photovoltaic glass processing. Background Technology

[0002] As a crucial component of solar panels, the cleanliness of photovoltaic glass directly impacts the photoelectric conversion efficiency of photovoltaic modules. With the rapid development of the photovoltaic industry, cleaning technologies in photovoltaic glass processing are constantly evolving. Early cleaning techniques relied primarily on manual handheld equipment, resulting in low efficiency and significant water waste. With technological advancements, automated cleaning equipment has gradually replaced manual cleaning. Through the coordination of robotic arms and water jet motors, automated cleaning of photovoltaic modules has been achieved, improving both cleaning efficiency and quality.

[0003] Currently, most photovoltaic glass processing and cleaning equipment on the market uses spray pipes for cleaning. The common universal bamboo-joint water pipe design can only locally remove glass powder adhering to the glass surface, resulting in unsatisfactory cleaning effects and seriously affecting the quality of photovoltaic glass. Furthermore, the spacing between the processed glass panes prevents the cleaning water from being evenly distributed across each pane, leading to water waste. Although some companies have introduced high-transparency photovoltaic glass cleaning devices that improve cleaning efficiency through adjustable glass clamps and mobile cleaning mechanisms, overall, existing cleaning equipment still needs improvement in terms of automation, cleaning effectiveness, and water resource utilization efficiency.

[0004] Although existing photovoltaic glass processing cleaning equipment has achieved a degree of automation, several significant shortcomings remain. First, the cleaning effect is unsatisfactory, failing to thoroughly remove dirt from the glass surface, a major obstacle for the photovoltaic industry, which pursues high photoelectric conversion efficiency. Second, existing equipment is not designed to effectively reduce the amount of glass dust entering the cleaning machine, increasing maintenance and upkeep frequency and operating costs. Third, the inability to evenly distribute cleaning water to every piece of glass not only affects cleaning quality but also wastes water resources. Finally, existing technology is insufficient in reducing glass surface temperature and improving workshop production efficiency; these issues limit the improvement of photovoltaic glass processing efficiency and product quality. Therefore, designing a new type of spray pipe cleaning equipment with a high degree of automation that effectively reduces dust entry, lowers glass surface temperature, and improves production efficiency is particularly urgent and necessary. Utility Model Content

[0005] The main purpose of this utility model is to propose a cleaning equipment and system for photovoltaic glass processing, which aims to solve the technical problems of poor cleaning effect and waste of water resources when using clean water to clean glass during photovoltaic glass processing, resulting in low cleaning efficiency.

[0006] To achieve the above objectives, this utility model proposes a photovoltaic glass processing cleaning device, installed above a conveyor roller conveyor, on which raw glass sheets to be cleaned are arranged; the photovoltaic glass processing cleaning device includes:

[0007] Controller;

[0008] A position detection device, wherein the position detection device is mounted above the conveyor roller conveyor and is oriented toward the conveyor roller conveyor; and,

[0009] A cleaning mechanism includes a spray pipe and a water supply tank. The spray pipe is connected to the water supply tank and is positioned above the conveyor roller conveyor. The spray nozzles of the spray pipe face the conveyor roller conveyor. The spray pipe and the position detection device are spaced apart. The conveyor roller conveyor, the position detection device, and the cleaning mechanism are all communicatively connected to a controller. The controller can control the position detection device to detect the original glass sheet and open the spray nozzles when the original glass sheet corresponds to the spray pipe to clean the original glass sheet on the conveyor roller conveyor.

[0010] In one embodiment, the spray pipe is further provided with a regulating valve, which is communicatively connected to the controller. The controller can open the regulating valve when the raw glass corresponds to the spray head to clean the raw glass on the conveyor roller.

[0011] In one embodiment, a pressure boosting valve is also provided on the spray pipe.

[0012] In one embodiment, there are multiple spray heads, which are spaced apart above the conveyor rollers, and the distribution direction of all the spray heads intersects with the movement direction of the conveyor rollers.

[0013] In one embodiment, the distance between any two adjacent spray heads is A, where 5cm ≤ A ≤ 10cm.

[0014] In one embodiment, the nozzles of each spray head are set at an angle to the surface of the original glass sheet.

[0015] In one embodiment, the cleaning mechanism further includes a cleaning component, which is spaced apart from the spray head and disposed on the rear side of the spray head.

[0016] In one embodiment, the height difference between the spray head and the conveyor roller is 150 mm.

[0017] In one embodiment, a wastewater collection tank is also provided below the conveyor roller conveyor.

[0018] Based on the same technical concept, in a second aspect, this utility model also proposes a photovoltaic glass processing cleaning system, which applies the photovoltaic glass processing cleaning equipment described in the first aspect.

[0019] The technical solution of this utility model involves setting up a controller, a position detection device, and a cleaning mechanism. In use, the position detection device is installed above the conveyor rollers, facing the conveyor rollers, and the spray pipes are also installed above the conveyor rollers, with the conveyor rollers and spray pipes spaced apart. The controller controls the position detection device to detect the original glass sheet, and opens the spray head when the original glass sheet aligns with the spray pipe, cleaning the original glass sheet on the conveyor rollers. This allows the utility model to open the spray pipe and perform the spraying operation only when the original glass sheet aligns with the spray pipe, thus avoiding the defects of poor cleaning effect and waste of water resources caused by continuous water spraying, and improving cleaning efficiency.
