Automatic drill bit restoration device and control method thereof

Abstract

The invention discloses an automatic drill bit restoration device and a control method thereof. A drill bit is driven by a motor to make elevating motion. The automatic drill bit restoration device comprises a fan-shaped part and an original-point detection sensor, wherein the fan-shaped part is driven by the motor to make rotating motion, and the original-point detection sensor is fixed on a drill bit base and used for detecting an end point of the fan-shaped part so as to judge whether the drill bit is restored to an original point; the original-point detection sensor outputs a detection signal to the controller, the controller controls the motor according to the detection signal of the original-point detection sensor so as to enable the drill bit to be restored to the original point. The drill bit base is provided with the original-point detection sensor and the fan-shaped part which is driven by the motor to make rotating motion, whether the drill bit is restored to the original point can be judged by detecting the end point of the fan-shaped part according to the original-point detection sensor, the automatic restoration of the drill bit after the drilling at every time can be realized, the accumulated error is reduced, and the accuracy of the drill bit original-point position and the traveling distance can be guaranteed.

Description

technical field [0001] The invention relates to the field of glass drilling machines, in particular to an automatic reset device for a drill bit and a control method thereof. Background technique [0002] Glass drilling machine is a machine used for glass drilling, which is indispensable in glass processing and production. Existing glass drilling machines usually use two drill bits for drilling up and down. In the existing glass processing field, the original position and travel distance of the drill bit are generally set artificially for drilling. During the reset process of the drill bit, due to pulse loss and mechanical The deviation in the mechanism causes the actual position of the drill bit to be inconsistent with the set position after running for many times, and the cumulative error expands. It is often necessary to use manual experience to judge whether the drill bit is reset in place or use a ruler to manually measure the actual position of the drill bit, and then ...
