Abstract

The invention discloses an automatic chip removal device for a PCB drilling machine. The automatic chip removal device for the PCB drilling machine comprises a rack, a drill bit, a first sleeve, air cylinders, a second sleeve, a nylon pad, an air sleeve and an air nozzle. In the work process, the air cylinders act to push the first sleeve to slide downwards, so that a part to be machined is pressed by the nylon pad; and then compressed air is blown into the air sleeve through a quick coupling and directly sprayed to the drill bit and the machining portion through the air nozzle fixedly connected with the air sleeve, and chips generated in the machining process are blown up and then discharged through a chip removal pipe joint. The automatic chip removal device is simple in structure, the chips generated in the machining process are removed effectively, the drill bit is cooled effectively, the service life of the drill bit is prolonged, and the drilling quality is improved; and the part to be machined is pressed and located in an auxiliary manner, so that the size accuracy of the part to be machined is improved.

Description

technical field [0001] The invention relates to a dust removal device, in particular to an automatic chip removal device for a PCB drilling machine. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is a printed circuit board, also known as a printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. It has developed to double-sided, multi-layer and flexible, and still maintains its own development trend. Due to the continuous development in the direction of high precision, high density and high reliability, the volume is continuously reduced, the cost is reduced, and the performance is improved, making printed boards In the future development of electronic equipment, it still maintains a strong vitality. PCB drilling machine is a kind of machine used in the drilling process of PCB processing. The PCB board must drill small holes on the board...
