Description

Technical Field

[0001] The present application relates to the technical field of circuit board production, and specifically to a circuit board splitting device capable of filtering dust airflow. Background Art

[0002] During the manufacturing process of circuit boards, it is usually necessary to cut a whole circuit mother board to meet specific production requirements. However, the dust generated during the material cutting process is scattered in the surrounding air, which will cause great harm to human health if inhaled by people. Therefore, an air flow filtering mechanism is usually used to absorb and filter the dust during cutting.

[0003] The Chinese utility model patent with the publication number CN221136121U discloses a cutting device for circuit board production, including a bottom plate. A support frame is installed at the right edge of the upper surface of the bottom plate. A second telescopic cylinder is installed at the left end of the upper surface of the support frame. A purification tank is installed on the upper surface of the support frame on the right side of the second telescopic cylinder. An air inlet pipe is installed through the left surface of the purification tank. A filtering mechanism is arranged on the upper surface of the purification tank on the right side of the exhaust pipe. In this utility model, the dust gas generated during cutting is pumped into the interior of the purification tank by an air pump and adsorbed by the clear water inside the purification tank. The water pump pumps the clear water into the filtering seat and filters it through the filter body. This avoids the adsorption saturation of the clear water in a short time, so there is no need to frequently replace the clear water, reducing the waste of water resources. And when the clear water is discharged from the drain hole, it can also purify the gas again, improving the dust treatment efficiency.

[0004] A bottom plate is provided in this device, and a support frame is installed on the upper surface of the bottom plate. When cutting the circuit board, the generated dust is sucked through the air inlet pipe and the air pump, and then filtered in the purification tank. However, during cutting, both the circuit board and the cutting mechanism are in an exposed state, and the position of the air inlet pipe is fixed, making it difficult to completely absorb the generated dust, prone to dust dispersion, and the dust removal efficiency is not high.
