Description

Technical Field

[0001] This utility model relates to the field of circuit board welding, and in particular to a fume purification device for circuit board welding. Background Technology

[0002] Circuit boards are key components in electronic devices, used to support and connect electronic components. They connect various electronic components through conductive lines, pads, and other features to form a complete circuit system. Circuit boards make circuits miniaturized and more intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can also be called printed circuit boards or printed circuit boards. Circuit board production requires soldering.

[0003] Circuit board soldering is a key process for fixing electronic components onto circuit boards and achieving electrical connections. The soldering quality directly affects the performance and reliability of the circuit. Most existing soldering devices use soldering irons, which generate soldering fumes that diffuse into the soldering environment and cause serious air pollution. To address this issue, we propose a circuit board soldering fume purification device. Utility Model Content

[0011] In a further embodiment, a control switch is fixedly connected to the front of the purification box, and a protective box is provided on the outer surface of the control switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device combines a fixed ear with a fixed cover. The fixed cover is installed on the circuit board soldering table and connected to a suction pipe via a built-in dust suction cover. Utilizing the negative pressure effect generated by the negative pressure fan on the purification chamber, the fumes generated during circuit board soldering are sucked into the purification chamber. Inside the purification chamber, there are activated carbon mesh, filter mesh, and metal wire mesh. These components work together to effectively purify the sucked-in fumes, thereby filtering out particulate matter. This design effectively solves the problem of welding fumes spreading in the welding environment and seriously polluting the air during the welding process. Attached Figure Description
