Up-down dust suction device of PCB distributor

Abstract

The invention relates to an up-down dust suction device of a PCB distributor. The up-down dust suction device of the PCB distributor comprises an upper dust suction assembly and a lower dust suction assembly. The upper dust suction assembly comprises a base, a machining unit and an upper dust suction unit, wherein the machining unit and the upper dust suction unit are connected to the base; the machining unit comprises a driver connected to the base, a sliding base slidably connected to the base and connected with the driver, a spindle installed on the sliding base, and a milling cutter installed on the spindle; the upper dust suction unit comprises a driving piece connected to the base, a sliding plate slidably connected to the base and connected with the driving piece, and an upper dust suction cylinder installed on the sliding plate; and the upper dust suction cylinder is arranged on the spindle in a sleeving mode, and the center axis of the upper dust suction cylinder coincides with the center axis of the milling cutter. The lower dust suction assembly comprises a mounting plate and a dust suction trough connected to the mounting plate. The dust suction trough is arranged towards the upper dust suction cylinder. The up-down dust suction device of the PCB distributor achieves wrapping type dust suction operation and direct drawing type dust suction operation during distribution of PCBs, the dust removal rate is improved, and dust is prevented from being leaked out.

Description

technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to an upper and lower dust suction device of a PCB splitter. Background technique [0002] PCB (Printed Circuit Board, printed circuit board) is the carrier of electrical connection of electronic components. In the industry, in order to achieve mass production of PCBs, multiple PCBs are generally fabricated on one board, and then each PCB is cut by a PCB splitter. When cutting the PCB, dust will be generated, and if the dust remains on the PCB, it will damage the electronic circuit of the PCB. The traditional PCB splitting machine is equipped with a vacuum cleaner next to the main shaft, and the dust is sucked while the milling cutter is cutting the PCB, so as to reduce the probability of dust falling on the PCB. However, since the dust generated when cutting the PCB will splash in all directions, it is difficult to completely remove the dust and prevent the dust...

Problems solved by technology

However, since the dust generated when cutting the PCB will splash in all directions, it is difficult to completely remove the dust and prevent the dust from leaking only with the vacuum cleaner installed next to the spindle, which not only affects the product quality of the PCB, but also endangers the safety of the workplace
