Dust absorption device for circuit board processing equipment

Abstract

The invention discloses a dust absorption device for circuit board processing equipment. The dust absorption device comprises a pipeline assembly, wherein the pipeline assembly comprises a dust collection pipe and a plurality of dust absorption pipes; the dust collection pipe is provided with an air outlet and a plurality of air inlets; the air outlet is used for communicating with an airflow generator; the air inlets are used for correspondingly communicating with the dust absorption pipes, and the plurality of air inlets are formed in the peripheral wall of the dust collection pipe in a staggered manner; and airflow in the dust absorption pipes enters the dust collection pipe in a first direction when passing through the air inlets, and the first direction is inclined relative to the axial direction of the dust collection pipe. According to the dust absorption device for the circuit board processing equipment, the airflow of any two air inlets in the dust collection pipe cannot form opposite impact, so that the loss of airflow suction force is avoided; and spiral airflow generated by a plurality of air suction ports tends to be superposed, and powdered scraps in the dust absorption pipes can enter the dust collection pipe along with the airflow more easily, so that the dust absorption efficiency can be improved.

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
