Full-automatic drill grinder

Abstract

The invention provides a full-automatic drill grinder. The full-automatic drill grinder comprises a transposition device as well as a feeding device, a grinding device, a detection device and a discharge device which are located around the transposition device, wherein the transposition device comprises a transposition disk and clamping heads arranged on the transposition disk, drills are mounted on the clamping heads through the feeding device, and then the transposition disk is rotated, so that the drills sequentially passes through the grinding device, the detection device and the discharge device for corresponding processing, a whole grinding process can be finished after one-time clamping, both the dismounting time of the drills and errors can be reduced, and the auxiliary time is shortened; servo motors are mounted behind the clamping heads and used for driving the drills on the clamping heads to rotate, so that grinding angles of the drills are adjusted correctly; and the drill grinder is controlled by a program and high in accuracy, the pass percent of the drills is increased, the labor condition is improved, the problems that workers are prone to fatigue and sight losing due to work under microscopes for a long time are solved, and the full-automatic drill grinder is widely applicable to grinding machining of various fine drills.

Description

technical field [0001] The invention relates to a grinder, in particular to a fully automatic drill bit grinder. Background technique [0002] Printed Circuit Board (PCB for short) is an important basic component of the electronic circuit industry. Its multilayer printed circuit board is the most widely used. Generally, there are thousands of small-diameter holes on the multi-layer board (the diameter of the holes is mostly less than 1mm, most of them are less than 0.6mm, and the smallest diameter is 0.15mm), and the pins of electronic components pass through these small holes. Connect to the circuit of the corresponding layer. For the processing of the above-mentioned numerous small holes, the conventional and mainstream process is the mechanical processing method of drilling with a drill bit. The material of the drill bit is hard alloy such as tungsten carbide. Although the material of the drill bit is very hard, after a certain number of holes are processed, the drill ...

AI Technical Summary

Problems solved by technology

Grinding with a manual grinder requires skilled operators and good eyesight. One person can only look at one machine. The work frequency is high, tiring, and the efficiency is not high. Moreover, the grinding amount of manual grinding is large, and a drill bit weighs about 100%. It can no longer be used after grinding 3 times, resulting in a serious waste of resources
