Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to an adjustable circuit board flattening device. Background Art

[0002] PCBs, made of copper, provide the electrical connections for electronic components. The primary advantage of using PCBs is that they significantly reduce wiring and assembly errors, improving automation and productivity. To extend the lifespan of PCBs, most companies typically plate a thin layer of gold on the surface. Before gold plating, the PCBs need to be flattened to ensure that the ions in the plating solution adhere efficiently to the surface.

[0003] After searching, the prior art has the publication number: CN211074790U, which discloses a flattening device for circuit board production, including a base, a vertical rod and a guide rod, wherein vertical rods are fixedly installed on both sides of the upper end of the base, a guide rod is fixedly connected between the upper parts of the two vertical rods, a sliding sleeve is provided on the guide rod, and a screw rod is fixedly connected between the lower parts of the two vertical rods, and a motor is fixedly installed on one side of the vertical rod through a mounting plate, and the output end of the motor passes through the vertical rod and is fixedly connected to one end of the screw rod. The flattening of the circuit board is achieved through the cooperation between the set flattening mechanism, the telescopic cylinder, the support plate, the mounting seat and the flattening roller. When in use, the telescopic cylinder is driven downward, thereby driving the support plate and the flattening roller to move downward, so that the flattening roller and the surface of the circuit board are in contact, and then the motor is driven to work, and the motor drives the screw rod to rotate, thereby realizing the movement of the screw sleeve, so that the screw sleeve moves back and forth left and right on the screw rod, thereby driving the flattening roller to flatten the upper surface of the circuit board, thereby realizing the flattening of the circuit board.
