Description

Technical Field

[0001] The invention relates to the technical field of circuit board manufacturing, and in particular to a manufacturing device for a double-sided PCB circuit board. Background Art

[0002] When manufacturing and processing double-sided PCB circuit boards, they are often subjected to spray etching. At present, spray etching equipment is often used to spray etching circuit boards. When using spray etching equipment for etching, generally only one side can be etched first. When the other side needs to be etched, the circuit board needs to be turned over after the single-sided etching is completed and then the other side is etched. The process is inconvenient, and due to the intermolecular force of the solution, the solution is very easy to condense into beads after spraying, resulting in uneven etching. After etching, the circuit board needs to be cleaned, and more waste liquid will be generated after cleaning. These waste liquids are directly discharged to cause waste. However, if the waste liquid is used for recycling, the pollution of the waste liquid will gradually increase, affecting the cleaning effect.

[0017] Compared with the prior art, the present invention provides a manufacturing device for a double-sided PCB circuit board, which has the following beneficial effects:

[0018] 1. The manufacturing device of the double-sided PCB circuit board drives the rotating shaft to rotate by a driving motor, so that the driving wheel cooperates with the conveyor belt for transmission. When the roller is squeezed by the inclined surface of the driving plate, the piston presses the gas into the hollow frame, so that the air bag expands and the PCB circuit board can be automatically positioned, thereby improving the convenience of manufacturing operations.

[0019] 2. The manufacturing device of the double-sided PCB circuit board is provided with three water pumps to extract liquid respectively, so that the liquid can be sprayed onto the PCB circuit board, thereby playing a cleaning role. After the PCB circuit board enters the cleaning chamber in advance, the cleaning operation can be performed for the first time, and then the cleaned liquid is filtered through the filter layer and flows into the next water chamber. Since there are three groups of spraying components, secondary return water cleaning and tertiary return water cleaning operations can be realized, thereby improving the utilization rate of the liquid and avoiding waste caused by direct discharge. In addition, the graded cleaning is adopted, which can automatically separate the seriously polluted waste liquid without the need for separate waste liquid treatment.

[0020] 3. The manufacturing device of the double-sided PCB circuit board drives the rotating shaft to rotate by driving the motor, so that the transmission wheel and the belt cooperate to drive the material transfer assembly to move. When the second gear and the second gear rod are driven, the connecting cylinder drives the hollow frame to flip, so that the hollow frame can be cleaned on both sides. After cleaning, the first gear and the first gear rod are driven. Since the diameter of the first gear is smaller than the diameter of the second gear, the transmission efficiency of the first gear and the first gear rod is greatly improved. The first gear drives the connecting cylinder to rotate quickly, and the PCB circuit board is rotated quickly to get rid of moisture, thereby greatly reducing the residual liquid and facilitating the drying operation of the PCB circuit board.

When the PCB circuit board enters the cleaning chamber 2011, the water pump 202 is used to take in liquid through the water inlet pipe 2033, and the liquid is discharged to the connecting cavity 2016 and the diversion shell 2014 through the water outlet pipe 2015, so that the nozzle 2013 sprays liquid to clean the PCB circuit board. The PCB circuit board can be flipped for multi-faceted cleaning, and the liquid after the initial cleaning can flow into the water cavity 2031 at the second position after cleaning, and be filtered through the filter layer 2012.
