PCB drilling mechanism

Abstract

The invention relates to a PCB drilling mechanism. The PCB drilling mechanism comprises a drill rod main shaft, a liquid cavity mechanism, a clamping ring mechanism, a pressing rod mechanism, a starting mechanism, a fan cylinder and a metal ring, wherein four notches are formed in the middle of the drill rod main shaft, limiting plates are arranged in the notches, limiting balls are arranged on the outer walls of the limiting plates, the clamping ring mechanism comprises a clamping ring arranged in the middle of the drill rod main shaft in a sleeving mode, an annular cavity formed in the innerside of the clamping ring and a limiting hole formed in the inner wall of the clamping ring and used for being clamped on the limiting balls, four arm rods are welded to the outer wall of the clamping ring, and the pressing rod mechanisms are further inserted into the four arm rods. In this way, a glue solution is smeared in a drill hole, components can be fixed in advance and welded convenientlyafter being inserted, functionality is improved again, an inserting hole type connecting plate is arranged at the top of the liquid cavity mechanism, the connecting plate can be detached from a drillrod main shaft switch according to needs, which is suitable for occasions where the liquid cavity mechanism does not need to be filled with the glue solution, and the application is more flexible.

Description

technical field [0001] The invention relates to the technical field of drilling devices, in particular to a drilling mechanism for a PCB circuit board. Background technique [0002] Printed circuit boards {Printed circuit boards}, also known as printed circuit boards, are providers of electrical connections for electronic components, collectively referred to as PCB circuit boards, circuit boards are used in the electronics industry, and are used to fix various components in integrated circuits. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. In the process of component replacement or maintenance, the drill spindle is often used to punch holes on the circuit board, and then the components Install. [0003] In the drilling process, it is necessary to use clamping equipment to fix the circuit board. These clamping devices are large i...

AI Technical Summary

Problems solved by technology

[0003] In the drilling process, it is necessary to use clamping equipment to fix the circuit board. These clamping devices are large in size and cannot be adapted to small workbenches, and the cost of large clamping equipment is high, and they are flexible, inventive, and functional. Poor, for example, during the drilling process, the drilled dust cannot be properly cleaned, etc.
