Description

Technical Field

[0001] The utility model relates to the technical field of reflow soldering, in particular to a reflow soldering machine with an auxiliary cleaning function. Background Art

[0002] Reflow soldering technology is not unfamiliar in the field of electronic manufacturing. The components on various boards used in our computers are soldered to the circuit board through this process. There is a heating circuit inside this equipment, which heats the air or nitrogen to a high enough temperature and blows it toward the circuit board with the components already attached, so that the solder on both sides of the components melts and then bonds to the mainboard. The advantage of this process is that the temperature is easy to control, oxidation can be avoided during the soldering process, and the manufacturing cost is easier to control.

[0003] The patent with application number CN201820963893.3 discloses a reflow soldering machine with an auxiliary cleaning function. In this technical solution, a reflow soldering machine housing, an inlet, an outlet, a conventional exhaust port, a first pipe, a smoke hood, a second pipe and other structures are used to solve the problem that when the amount of smoke is large during the production process, a part of the smoke will flow along the outlet to the production workshop, which will not only affect the product quality but also pollute the production workshop and affect the health of the operators. However, in this technical solution, there is no function of cleaning the reflow soldering feeder belt, so it is easy to cause welding slag to remain on the feeder belt, which in turn affects the normal use of the reflow soldering. At the same time, the operator is also required to clean it regularly, which increases the labor intensity of the operator and reduces the production efficiency. Utility Model Content
