Abstract
Description
Technical Field
[0001] This application relates to the field of PCB board production equipment technology, and in particular to a PCB board surface cleaning device. Background Technology
[0002] With the rapid development of the electronics and information industry, printed circuit boards (PCBs), as the core carriers of electronic products, have complex manufacturing processes and extremely high cleanliness requirements. If flux, oxides, dust, or microparticles remain on the PCB surface before soldering and assembly, it will not only affect the wettability and reliability of the solder joints but may also lead to quality problems such as short circuits and open circuits. Therefore, PCB cleaning equipment has become an essential process in production lines for SMT (Surface Mount Technology), wave soldering, and final assembly. Traditional PCB cleaning methods include brushing, ultrasonic cleaning, and air knife blowing. However, with the diversification of PCB sizes, increased structural complexity, and the continuous improvement in requirements for cleanliness, production capacity, and automation, a single cleaning mode is no longer sufficient to meet the needs of modern electronic manufacturing.
[0003] However, existing PCB board cleaning equipment still has significant shortcomings in actual operation: First, fixed or simply adjustable clamping mechanisms can often only adapt to a few types of boards, making it difficult to achieve fast and stable clamping of PCBs of different specifications, thicknesses, or with irregularly shaped components. This can easily lead to board displacement, uneven cleaning, or clamp interference, reducing the equipment's versatility and clamping reliability. Second, flux residue, residual dust, and solder slag generated during traditional cleaning processes are mostly scattered in the cleaning area, lacking efficient collection and discharge devices. This not only increases the frequency of manual cleaning and extends downtime but may also cause secondary contamination of subsequent processes. Finally, existing equipment often uses external drawers or filters to handle impurities after cleaning, which is inconvenient to clean and cannot monitor the accumulation of residue in real time, making timely maintenance difficult and affecting cleaning efficiency and production continuity.
