Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board manufacturing technology, and more specifically to a rotary PCB automatic cleaning device. Background Technology

[0002] After the PCB circuit board is processed, a protective layer needs to be coated on its surface. Before coating the PCB circuit board, the resin residue on the surface of the PCB circuit board needs to be cleaned off to avoid cracks in the coated protective layer.

[0003] A circuit board cleaning device is provided in the prior art, belonging to the field of circuit boards. The circuit board cleaning device includes a cleaning body, connecting rods, hinged rods, and a lifting mechanism. A lifting chamber is provided on the lower side of the cleaning body, and four connecting rods are located within the lifting chamber. Hinged rods are hinged to the upper side of the connecting rods, with the number of hinged rods corresponding to the number of connecting rods. A torsion spring is provided at the hinge point between the connecting rod and the hinged rod. The torsion spring, through its elastic force, moves the two hinged rods away from each other. This solution uses elastic force to increase friction, thus fixing the circuit board and allowing it to rise and fall during cleaning, enabling the detergent to flow fully onto the circuit board surface and improving the cleaning effect.

[0004] In the aforementioned prior art, the cleaning process involves driving the circuit board to rise and fall, allowing the detergent to thoroughly clean the surface of the circuit board, thereby achieving the purpose of cleaning the circuit board. However, during the cleaning process, the detergent can only flow on one side of the circuit board. If the other side of the circuit board cannot be cleaned, workers need to remove the circuit board and fix it with the other side facing up before the other side of the circuit board can be cleaned. This operation is too complicated, which not only reduces cleaning efficiency but also increases labor costs. Utility Model Content
