Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic glass coating, and in particular to a double-sided coating process and device for photovoltaic glass. Background Art

[0002] Photovoltaic glass refers to special glass used in solar photovoltaic power generation systems. It is an indispensable component of solar power generation systems. It has light transmittance, anti-reflection, weather resistance and durability. It is mainly used to protect solar cells in photovoltaic modules to ensure their performance and durability under various environmental conditions. It is widely used in construction, transportation, agriculture and other fields.

[0003] During the production of photovoltaic glass, the photovoltaic surface needs to be coated to improve the performance, efficiency and durability of the glass. Currently, when coating photovoltaic glass, the surface of the glass needs to be cleaned in advance. However, most of the current glass coating processing devices need to independently set up a cleaning mechanism to clean the surface of the glass when in use, which increases the processing steps and affects the processing efficiency. In addition, since both sides of the glass need to be coated, the glass needs to be flipped. In the process of moving and flipping the glass, the outer surface of the glass is easily contaminated with dust and impurities, which can easily affect the coating on the other side of the glass.

[0061] Working principle: First, turn on the No. 1 electric cylinder 107 to drive the installation frame 201 to move, and the movement of the installation frame 201 drives the rotating frame 202 to move. After it moves into place, turn on the No. 2 motor 203 to drive the rotating frame 202 located inside the installation frame 201 to rotate. At this time, the rotation of the rotating frame 202 drives the suction cup 204 to move, so that the suction cup 204 and the photovoltaic glass are in contact and the photovoltaic glass is adsorbed. At this time, turn on the No. 2 motor 203 to drive the rotating frame 202 to rotate, and the rotation of the rotating frame 202 drives the photovoltaic glass to rotate, so that the photovoltaic glass is in a horizontal position, and turn on the No. 1 electric cylinder 107 to drive the photovoltaic glass to move, so that the photovoltaic glass moves to the rotating wheel 103;

At this time, the cleaning agent is sprayed on the upper surface of the photovoltaic glass through the nozzle 409, and the upper surface of the photovoltaic glass is cleaned through the cleaning plate 407. In the process of moving, when the push strip 507 and the sealing plate 419 are in contact, the sealing plate 419 is pushed to move, so that the sealing plug of the sealing plate 419 is separated from the storage box 411. At this time, the storage box 502 and the storage box 411 are connected through the connecting pipe 506. Through the principle of the communicating vessel, the cleaning liquid inside the storage box 502 enters the storage box 411 to replenish the storage box 411;

When the coating is completed, the No. 2 electric cylinder 303 is turned on to drive the moving plate 302 to move, and the movement of the moving plate 302 drives the rotating frame 202 to move, and the movement of the rotating frame 202 drives the suction cup 204 to move, so that the suction cup 204 and the photovoltaic glass are in contact, and the photovoltaic glass is adsorbed and fixed, and then the No. 4 motor 304 is turned on to drive the rotating frame 202 located between the moving plates 302 to rotate, so as to flip the photovoltaic glass;

[0064] Finally, during the flipping process, the No. 5 motor 305 is turned on to drive the conveyor belt 206 between the movable plates 302 to move, and the movement of the conveyor belt drives the movable frame 401 between the movable plates 302 to move, thereby cleaning the lower surface of the photovoltaic glass. At this time, when the flipping is completed, the flipping mechanism 3 is reset. During the resetting process, when the trapezoidal block on the side of the fixed bar 306 and the sealing plate 419 on the storage box 411 located on one side of the movable plate 302 contact, the sealing plate 419 is pushed to move, so that the sealing plug of the sealing plate 419 is separated from the interior of the storage box 411, thereby replenishing the storage box 411 with liquid.
