Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component production equipment, and particularly relates to an automatic electronic component cleaning machine. Background Art

[0002] In the process of manufacturing electronic components, soldering is a common and important technological process. By plating tin on the pins of electronic components, the soldering performance of the components on the circuit board can be improved, ensuring good electrical connection and mechanical strength. However, during the soldering process, impurities such as flux residues, solder dross, or paint coatings of copper wires often remain on the bottom or pins of electronic components. If these residues are not removed in time, they may affect the performance and reliability of the components.

[0003] Currently, factories usually use manual methods to clean the soldering residues on electronic components. Operators dip a brush into the cleaning agent and manually scrub the surface and pins of the components to remove the residual impurities. However, this manual cleaning method has many drawbacks. First, during the time interval from the completion of the soldering process to manual cleaning, the electronic components will cool to a certain extent, making the residues more difficult to remove, and a large amount of time and manpower need to be invested. Second, long-term contact with the cleaning agent may have an adverse impact on the health of operators, such as skin irritation or respiratory problems. In addition, the efficiency and quality of manual cleaning are difficult to guarantee, and problems such as incomplete cleaning or missed cleaning are likely to occur, affecting the consistency and qualification rate of products.

[0004] With the rapid development of the electronic manufacturing industry, the production scale and quality requirements of electronic components are constantly increasing. The traditional manual cleaning method can no longer meet the needs of modern production. Therefore, there is an urgent need for an automated electronic component cleaning device that can efficiently and thoroughly remove soldering residues, while reducing the manual labor intensity and health risks, and improving production efficiency and product quality.
