Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel spraying, specifically a solar photovoltaic panel spraying machine with coating grinding function. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). During the process of PV modules generating electricity from sunlight, atmospheric dust can affect the exposed photovoltaic panels and reduce their power generation efficiency. Currently, the common solution is to coat the sun-receiving side of the photovoltaic panel with a coating.

[0003] Currently, when applying coatings to the light-receiving surface of photovoltaic panels, the surface is not perfectly smooth due to paint splattering and dust, which reduces the coating effect. Therefore, the coating needs to be sanded to achieve good flatness and maximize its effect. However, dust is inevitably generated during coating sanding, which further deteriorates the coating effect. To address this, we propose a solar photovoltaic panel spraying machine with a coating sanding function. Utility Model Content

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0023] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] A solar photovoltaic panel spraying machine with coating grinding function includes a conveyor belt 1, and a spraying component 2, a drying component 3 and a grinding component 4 are arranged sequentially along the conveying direction of the conveyor belt 1.

[0025] The spraying assembly 2 includes a nozzle 22 and a first bracket 21 fixedly installed on the side of the conveyor belt 1. The nozzle 22 is slidably mounted on the first bracket 21, and a driving component is also fixedly installed on the first bracket 21. The driving component causes the nozzle 22 to reciprocate on the first bracket 21. The nozzle 22 sprays paint, and works with the conveyor belt 1 to perform spraying operations on the surface of the solar photovoltaic panel.

[0026] To improve the curing rate of the coating, a drying assembly 3 is provided. The drying assembly 3 includes a fan 31 and a hot air hood 32 fixed on the conveyor belt 1. The output end of the fan 31 is connected to the upper surface of the hot air hood 32 through a connecting pipe 33, and a filter element 331 is provided inside the connecting pipe 33. The filter element 331 can prevent the air blown out by the fan 31 from carrying dust, which would cause the uncured coating to be contaminated with dust and damage the smoothness of the coating.

[0027] Due to paint splatter, dust, and other factors, the surface coating of the photovoltaic panel is not perfectly smooth, which reduces the coating effect and may accelerate the aging of the solar photovoltaic panel during future use. Therefore, a grinding assembly 4 is needed to grind the coating to improve its smoothness. The grinding assembly 4 includes a grinding head 42 and a second bracket 41 fixedly installed on the side of the conveyor belt 1. The grinding head 42 is slidably mounted on the second bracket 41, and a driving component is also fixedly installed on the second bracket 41. The driving component causes the grinding head 42 to reciprocate on the second bracket 41. Thus, the grinding head 42 can completely grind the solar photovoltaic panel. Furthermore, the second bracket 41 is also provided with a lifting driving component to control the vertical movement of the grinding head 42, thereby realizing the adjustment of grinding pressure and grinding depth. In this embodiment, the driving component can be a drive motor or a hydraulic push rod, etc.

[0028] In some embodiments, a suction cup 5 for fixing the solar photovoltaic panel is also provided at the position of the conveyor belt 1 corresponding to the grinding component 4. The suction cup 5 can move in the vertical direction. The suction cup 5 provides a firm lock on the solar photovoltaic panel, thereby preventing the solar photovoltaic panel from shaking during the grinding process; at the same time, the suction cup 5 can move in the vertical direction without interfering with the conveying of the solar photovoltaic panel.

[0029] In some embodiments, a dust suppression component is provided on the outer side of the grinding head 42. The dust suppression component includes a dust suppression sleeve 43 and a suction sleeve 44. The dust suppression sleeve 43 is arranged in a circular cylindrical structure. Suction holes 431 are evenly distributed on the inner sidewall of the dust suppression sleeve 43. The dust suppression sleeve 43 is fitted inside the suction sleeve 44. A fleece layer 441 is provided at the lower end of the suction sleeve 44. The suction sleeve 44 is connected to a suction pipe 442, which creates a negative pressure inside the suction sleeve 44. The grinding head 42 is rotatably disposed inside the dust suppression sleeve 43. The dust suppression sleeve 43 can reduce the airflow velocity generated when the grinding head 42 rotates, thereby preventing excessive dust stirring and also facilitating the suction sleeve 44 to remove dust. The suction holes 431 are evenly distributed on the inner sidewall of the dust suppression sleeve 43, allowing dust to enter the suction sleeve through the suction holes 431 and be sucked away by the suction pipe 442. The velvet layer 441 is made of soft material, which can prevent the bottom of the dust cover from bumping into the solar photovoltaic panel. At the same time, the movement of the velvet layer on the solar photovoltaic panel can also remove the floating dust on the solar photovoltaic panel.

[0030] In some embodiments, the grinding head 42 is arranged in a circular structure, and a flatness detector 421 is also provided on the grinding head 42. The flatness detector 421 is electrically connected to the conveyor belt 1 and can perform multi-point detection on the solar photovoltaic panel. Furthermore, the conveyor belt 1 corresponding to the grinding assembly 4 is independently set, so the movement of the solar photovoltaic panel can be adjusted individually, which is beneficial for the grinding assembly 4 to grind the coating of the solar photovoltaic panel.

[0031] In some embodiments, a ceramic heating element 321 and an air distribution plate 322 are sequentially arranged inside the hot air hood 32 along the direction close to the conveyor belt. The air distribution plate 322 has uniformly distributed through holes, and the inner wall of the hot air hood 32 is coated with an infrared reflective coating. The air distribution plate 322 slows down and evens out the air blown out by the fan 31, preventing excessively fast airflow from blowing onto the uncured coating and exacerbating the unevenness of the coating. The ceramic heating element 321 accelerates the curing of the coating by increasing the temperature, while the infrared reflective layer effectively prevents heat loss.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
