Description

High-cleanliness high-temperature-resistant net belt assembly Technical Field The utility model relates to the technical field of reflow soldering equipment, in particular to a high-cleanliness high-temperature-resistant mesh belt assembly. Background Reflow ovens, also known as reflow soldering machines or "reflow ovens," are devices that provide a heated environment to melt solder paste and thereby reliably bond surface mount components and PCB pads together through a solder paste alloy. The structure of reflow soldering furnace mainly comprises heating system, conveying system and cooling system triplex, heating system realizes even hot-blast circulation through upper and lower temperature zone independent accuse temperature and cooperation rectification board, conveying system contains parts such as stainless steel guipure, guide rail, ensure PCB board steady transmission, cooling system then solidifies the solder joint fast in order to guarantee welding quality, because stainless steel guipure wholly is flexible guipure, can be because gravity downwarping, so normally set up stainless steel support bar below the stainless steel guipure, make the lower extreme of stainless steel guipure laminate with the top of stainless steel support bar, be used for supporting the stainless steel guipure, prevent that stainless steel guipure from taking place crookedly downwards. The belt assembly of traditional reflow oven keeps stainless steel mesh belt operation steady through stainless steel support bar's upper end and stainless steel mesh belt lower extreme contact, for stainless steel mesh belt provides the supporting effect, there is the high temperature region in the equipment, stainless steel mesh belt incessantly moves, stainless steel mesh belt constantly rubs with stainless steel support bar each other, the wearing and tearing of stainless steel mesh belt and stainless steel support bar have more been aggravated to the high temperature, can produce a lot of dust piece, need the periodic shutdown clearance, prevent dust piece and fall on PCB board surface, influence the welding effect of PCB board.
