The production process of PCB board includes many processes such as cutting, drilling, copper deposition, grinding, electroplating, film stripping, etching, etc., among which cleaning of circuit board is an important link. The circuit boards processed by different processes need to be sent to the cleaning machine for cleaning to remove solder mask, oil stains, fingerprints and other contaminants to avoid adverse effects on subsequent production and processing procedures.

[0003] To this end, a cleaning device for circuit board processing with announcement number CN215745130U includes a box body, a motor is fixedly connected to the left side of the box body, a rotating shaft is fixedly connected to the output end of the motor, a brush is fixedly connected to the side surface of the rotating shaft, a first hydraulic cylinder is fixedly connected to the inner bottom of the box body, a storage plate is fixedly connected to the output end of the first hydraulic cylinder, the left and right sides of the box body are fixedly connected to support plates, a second hydraulic cylinder is fixedly connected to the upper surface of the support plate, and a pressure plate is fixedly connected to the output end of the second hydraulic cylinder.

[0004] The problem with the prior art is that when a traditional device is used to clean a circuit board, it does not have the function of flipping the circuit board, so it can only clean one side of the circuit board. When cleaning the other sides, it needs to be manually flipped, which is inefficient. In addition, during the flipping and cleaning process, in order to prevent the circuit board from falling, it needs to be fixed. Therefore, we propose a cleaning device for circuit board processing.

When the servo motor or the dual-axis motor is started, they will drive the connecting rod on the surface of the rotating rod to move inside the limit plate. During the movement, the telescopic rod will be driven to flip. The electric push rod can drive the telescopic rod to extend and retract, which is convenient for moving the flushed circuit board to the top of the fan for air drying, thereby achieving the effect of providing power for turning over the circuit board during the flushing process.
