Cleaning tool for reflow welding furnace

Abstract

The invention discloses a cleaning tool for a reflow welding furnace. The cleaning tool for the reflow welding furnace comprises a scraper knife bracket, a first scraper knife, a second scraper knifeand a slide base; the first scraper knife and the second scraper knife are respectively mounted at the front and back ends of the scraper knife bracket; the first scraper knife comprises a first knifebody part, a connecting part and a first knife bit part; an included angle is preset between two planes corresponding to the connecting part and the first knife bit part; one end of the connecting part is connected with the first knife bit part, and the other end is connected with the first knife body part; the second scraper knife comprises a second knife body part and a second knife bit part; and the second knife body part and the second knife bit part are connected through screws and screw holes. Through the mode, the cleaning tool for the reflow welding furnace can easily, quickly and thoroughly remove residues on the inner cavity of a machine cavity and in narrow gaps, reduces the maintenance time, reduces the product pollution probability, reduces the defective percent and the scraprisk, is longer in use time, and can be disassembled to clean for recycling.

Description

technical field [0001] The invention relates to the field of cleaning tools, in particular to a cleaning tool for reflow ovens. Background technique [0002] Now when the product goes through the reflow oven welding process, the excess flux in the solder paste on the product passes through high temperature and forms a gaseous state that adheres to the inner wall of the machine cavity and the narrow gaps. As the cycle gets longer, there will be more and more, which will pollute the cavity. When the next production is carried out, more products may cause pollution or defects. Periodic preventive maintenance is required. In the past, when maintaining the machine, due to the narrow and limited space of the inlet and outlet tracks, it is very inconvenient to clean and it is difficult to clean it thoroughly. If it is not cleaned for a long time, it will cause a short circuit of the fan and other electrical appliances. Contents of the invention [0003] The main technical proble...

Problems solved by technology

The cycle will become more and more, and the cavity will be polluted. In the next production, there may be more products causing pollution or defective

It is necessary to do periodic preventive maintenance. In the past, when maintaining the machine, due to the narrow and limited space of the inlet and outlet tracks, it is very inconvenient to clean and it is difficult to clean it thoroughly. If it is not cleaned for a long time, it will cause a short circuit of the fan and other electrical appliances.
