Soldering flux spraying device and using method thereof

Abstract

The invention discloses a soldering flux spraying device. The soldering flux spraying device comprises a conveying system, a spraying system, a powder supply system and a powder recycling system, wherein the conveying system is used for conveying a to-be-sprayed plate in the horizontal direction, and uniform gaps are formed in the bottom of the conveying system; the spraying system comprises a frame main body and a spray gun arranged in the frame main body; the powder supply system is used for outputting soldering flux powder to the spraying system; and the powder recycling system is used forcollecting soldering flux powder which is not sprayed onto the to-be-sprayed plate. A traditional assembly line type device arranged in the horizontal direction is replaced. According to the solderingflux spraying device, the powder recycling system is creatively arranged at the bottom of the spraying system, the powder is recycled through the action of gravity, in addition, the spraying system is arranged above the to-be-sprayed plate, the to-be-sprayed plate is placed in the horizontal direction and replaces a traditional plate placed in the vertical direction, the influence of the gravityaction can be effectively overcome, and spraying can be more uniform.

Description

technical field [0001] The invention relates to the technical field of spraying devices, in particular to a flux spraying device and a use method thereof. Background technique [0002] At present, there are basically two types of flux spraying before brazing: spraying and powder spraying, and the overall structure of powder spraying generally adopts the hanging spraying method, and the plate to be sprayed is suspended at the nozzle of the spray gun, and the powder is absorbed by electrostatic The device absorbs the flux powder into the spray gun and sprays it out through the spray gun. Due to the assembly line arrangement of the spraying method, it occupies a large area, and the entire powder spraying system is bulky; in addition, the suspended assembly line cannot meet the spraying requirements of large-area plates, and most aluminum plates have no hanging parts. , requires special suspension parts; due to gravity and unreasonable setting of the spray gun position, it is e...

Problems solved by technology

Due to the assembly line arrangement of the spraying method, it occupies a large area, and the entire powder spraying system is bulky; in addition, the suspended assembly line cannot meet the spraying requirements of large-area plates, and most aluminum plates have no hanging parts. , requires special suspension parts; due to gravity and unreasonable setting of the spray gun position, it is easy to cause uneven spraying of the plate in the vertical direction, resulting in the situation that the upper layer is thinner than the lower layer; a little vibration will cause the powder to fall, which cannot be effectively controlled The thickness of the powder layer, etc.
