Problems solved by technology

[0003] At present, the exhaust air filter device of the reflow oven is independent of the top frame of the furnace, and is installed on the inlet and outlet sides respectively. Two exhaust motors need to be installed. The structure is relatively complicated, and the exhaust gas is not collected completely, and it will often return to the furnace or overflow to the outside of the furnace. , affecting the environment and product quality
In addition, when maintaining the stencil, maintenance personnel need to reach the inlet and outlet of the furnace. Usually, the space reserved for the SMT production line is limited, and the current device is inconvenient for equipment maintenance.

Abstract

The invention relates to an exhaust extraction and filtration device of a reflow soldering furnace. The exhaust extraction and filtration device comprises an extraction box shell, an extraction port cover plate and a filtration meshed plate, wherein the extraction port cover plate is mounted on the extraction box shell so as to form an extraction box body; and the filtration meshed plate is arranged in the extraction box body. Compared with the prior art, the exhaust extraction and filtration device has the advantages that the cost is reduced, the extraction and filtration effects are better,and the maintenance and the cleaning are more convenient.

Description

technical field [0001] The invention relates to a reflow soldering furnace, in particular to a waste gas suction filter device of the reflow soldering furnace. Background technique [0002] Reflow soldering furnace is a kind of soldering equipment in the SMT industry. This type of equipment provides a heating environment and heats air or nitrogen to a sufficient temperature to melt the solder paste and make surface mount components and circuit boards adhere reliably. connected together. In the actual production process, the flux part after the solder paste melts will form steam, and the flux vapor will condense on the surface with a relatively low temperature, and the reflow furnace is generally equipped with an exhaust device. Especially at the inlet and outlet of the reflow furnace, in order to prevent the mixture of flux and air or nitrogen from overflowing into the workshop, an exhaust air filter device will be installed at the inlet and outlet. [0003] At present, th...
