A spraying device for preventing the edge of the groove from being too thin for solar photovoltaic modules

Abstract

The invention discloses a spraying device for preventing too thin edge agent liquid of a solar photovoltaic module in the field of photovoltaic technology, comprising: a mounting seat; a spraying assembly, the liquid injection cylinder is movably installed on a fan-shaped plate through a connecting shaft; a swinging assembly , including an installation frame horizontally fixed on the front side of the installation base and located at the rear side of the spraying assembly; a detection assembly, the detection assembly is located at the right end of the installation frame; the present invention contacts and slides with the surface of the interconnection bar before the assembly is sprayed by the detection assembly, conducts electricity The contact between the sheet and the surface of the interconnection bar forms a closed circuit, and the conductive sheet is suspended in the air, driving the liquid injection nozzle to swing to the left and towards the left edge of the groove, and then the touch head contacts the sensor until the conductive sheet forms a closed circuit again, driving it Changing to a vertical state, effectively spraying evenly on the edge of the groove, avoiding the problem that the flux droplets are blocked by the inner wall of the groove and resulting in a thinner spray layer, ensuring the safety of subsequent welding and improving the finished product of welding Rate.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a spraying device for preventing the edge of a groove from being too thin for a solar photovoltaic module. Background technique [0002] Photovoltaic: It is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. At the same time, the classification of solar photovoltaic power generation systems, one is centralized, such as large-scale Northwest ground photovoltaic power generation systems; the other is distributed, such as industrial and commercial enterprise factory roof photovoltaic power generation systems, residential roof photovoltaic power generation systems. [0003] The composition and structure of the p...

Problems solved by technology

[0003] The composition and structure of the photovoltaic module interconnection strips are processed, for subsequent welding operations, the surface will be sprayed with flux. The spraying of the flux needs to be uniform, but the interconnection strips need to be grooved on the surface for installation requirements. When the spray structure When moving on the plane of interconnecting strips, the droplets sprayed onto the surface will splash around, but when the liquid spraying structure moves to the groove, the sputtered droplets are partially blocked by the inner wall of the groove, so that the edge of the groove will not It can receive the same amount of flux on the surface of the adjacent interconnecting strips, resulting in too thin spraying of the flux on the edge of the groove, resulting in insufficient subsequent welding protection, prone to damage to the interconnecting strips, and reducing the yield. For this reason, We propose a spraying device for solar photovoltaic modules to prevent the edge of the groove from being too thin
