Dust extraction device for circuit board processing equipment

Abstract

The invention discloses a dust suction device for circuit board processing equipment, comprising: a pipeline assembly, the pipeline assembly includes a dust collection pipe and a plurality of dust suction pipes, the dust collection pipe has an air outlet and a plurality of The air inlet, the air outlet is used to communicate with the airflow generating device, and the air inlet is used to communicate with the dust suction pipe; a plurality of the air inlets are arranged in a staggered manner on the peripheral wall of the dust collection pipe , when the airflow in the dust suction pipe passes through the air inlet, it enters the dust collection pipe in a first direction, and the first direction is set obliquely relative to the axial direction of the dust collection pipe. According to the dust suction device for circuit board processing equipment of the present invention, the airflows of any two air inlets on the dust collection pipe will not form a hedge, thereby avoiding the loss of air suction, and the spiral airflow generated by multiple air inlets tends to The superimposed situation makes it easier for the dust in the dust suction pipe to enter the dust collection pipe with the airflow, which is conducive to improving the dust collection efficiency.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a dust suction device for circuit board processing equipment. Background technique [0002] It is pointed out in the relevant technology that in the production process of printed circuit boards, for the connection between circuit layers and the installation of electronic components in the later stage, it is necessary to use a drilling machine to drill holes on the production board, and to drill holes on the circuit board according to the design requirements. Milling and forming. The drilling process is to use the drill bit connected to the main shaft on the drilling machine, through the high-speed rotation of the main shaft, the drill bit will drop the drill to drill a hole with the required aperture on the production plate. During the edge milling process, the milling cutter linked with the main shaft is used to mill the desired shape on the edge of the product...

AI Technical Summary

Problems solved by technology

During the drilling or edge milling process, a large amount of dust will be generated when the drill nozzle or milling cutter cuts the base material and copper foil, so it is necessary to install a dust suction device to absorb the dust to prevent the dust from clogging the drilling machine or edge milling machine and affecting the processing quality and machine tool life
