Problems solved by technology

The structure of the welding pen itself is very small. If the micro fan installed on it is too small, the wind force will not be enough to blow away the smoke. If the fan is too large, it will affect the staff holding the welding pen, which will affect the operation.

Abstract

The invention discloses a smoke exhaust device based on manual welding. The smoke exhaust device comprises a negative pressure generator. The negative pressure generator comprises a generator body. The generator body is provided with a fume suction port, a compressed air inlet and an exhaust port. A diffusion cavity is formed in the generator body. The fume suction port, the compressed air inlet and the exhaust port are communicated with the diffusion cavity. The fume suction port is formed above a to-be-welded electronic component. According to the scheme, the structure of an electric welding pen (electric soldering iron) does not need to be changed, and it is only needed for form the fume suction port above the to-be-welded electronic component; the negative pressure generator is started in the welding process, negative pressure is generated beside the fume suction port, fume generated in the welding process can be exhausted through the fume suction port, and the welding operation of workers is not affected by the device.

Description

technical field [0001] The invention relates to the field of welding of electronic components, in particular to a smoke exhaust device based on manual welding. Background technique [0002] As the complexity of electronic products increases, more and more components are used. Some electronic products (especially some large electronic equipment) use hundreds or even thousands of components, and the number of solder joints is tens of thousands. Soldering is an important process in the assembly process of electronic products. The quality of welding directly affects the performance of electronic circuits and electronic devices. Excellent welding quality can provide good stability and reliability for the circuit, and poor welding methods will cause damage to components, which will bring great difficulties to testing, and sometimes leave hidden dangers, affecting the reliability of electronic equipment. And a bad solder joint will affect the reliability of the entire product. S...
