Device for comprehensively removing blockages in small holes of circuit board

Abstract

The invention relates to the technical field of circuit boards, and discloses a device for comprehensively removing blockages in small holes of a circuit board. The device comprises a shell, wherein an air inlet is fixedly connected to the upper end of the shell, an inlet pipeline is fixedly connected to the lower end of the air inlet, a fan is movably connected to the left end of the inlet pipeline, the lower end of the fan is movably connected with an outlet pipeline, the lower end of the outlet pipeline is movably connected with a splitter plate, the outer surface of the fan is movably connected with a belt, the left end of the belt is movably connected with a rotating shaft, and the outer surface of the rotating shaft is movably connected with a gear. According to the invention, static friction motion between the rotating shaft and the gear is converted into sliding friction, so a clamping plate limits the circuit board; other redundant holes in the upper end of the splitter plate are blocked, so wind power is concentrated on the circuit board, and the wind power of outflow air is automatically concentrated according to the size of the circuit board; and the circuit board is limited, so shaking is prevented.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a device for comprehensively removing blockages inside small holes of the circuit board. Background technique [0002] With the gradual development of society, people's living standards have been significantly improved, making people's research and development of new materials continue to upgrade, and the use of circuit boards is one of them. As a substrate, circuit boards have high wiring density and weight. The characteristics of lightness, thinness, good bendability and energy saving are very popular among people. [0003] However, there are still defects that need to be overcome in the current processing of circuit boards. The circuit boards are large or small, and holes need to be drilled on the circuit boards. Blocking, in modern times, the hole is usually blown manually to open it calmly and remove the blockage in the hole, but it is time-consuming, and at the same...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for comprehensively removing blockages inside the small holes of the circuit board, which is automatic, and at the same time, according to the size of the circuit board, concentrates the wind force of the air outlet, and limits the position of the circuit board, The advantages of preventing vibration and automatically collecting blockages in the hole of the circuit board solve the problem of preventing a long time after punching. Because the hole is small, it is easy to be blocked by some impurities. In modern times, the holes are generally blown manually. Gas, open it calmly, and remove the blockage in the hole, but it is time-consuming. At the same time, the holes on some edges are not cleaned cleanly, and the blockage in the hole cannot be handled well.
