Spraying device for preventing agent liquid at groove edge from being too thin for solar photovoltaic module

Abstract

The invention discloses a spraying device for preventing agent liquid at the groove edge from being too thin for a solar photovoltaic module, and belongs to the technical field of photovoltaics. The spraying device comprises a mounting base, a spraying assembly, a swing assembly and a detection assembly; a liquid injection barrel is movably mounted on a fan-shaped plate through a connecting shaft; the swing assembly comprises a mounting frame which is horizontally fixed to the front side of the mounting base and located on the rear side of the spraying assembly; and the detection assembly is arranged at the right end of the mounting frame. The detection assembly makes contact with the surface of an interconnection strip and slides before the spraying assembly, a conducting plate makes contact with the surface of the interconnection strip to form a closed loop, the conducting strip is suspended, a liquid injection nozzle is driven to swing leftwards and face the left groove edge of the groove, a rear touch head makes contact with a sensor till the conducting plate forms a closed loop again, the liquid injection nozzle is driven to change into a vertical state, the groove edge of the groove is effectively and evenly sprayed, the problem that a spraying layer is relatively thin due to the fact that scaling powder liquid drops are blocked by the inner wall of the groove is solved, safety of follow-up welding is guaranteed, and the welding yield is increased.

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
