Drill bit grinding device and testing method

Abstract

The invention discloses a drill bit grinding device and a testing method. The drill bit grinding device comprises a grinding wheel mechanism for grinding a drill bit, a control device for fixing and adjusting the position of the drill bit, and an image acquisition device for acquiring an image of the drill bit, wherein when the image acquisition device acquires the image of the drill bit, image acquisition points of the image of the drill bit are positioned at the inner side of the grinding wheel, namely the image acquisition points of the image of the drill bit are positioned at the inner side of the grinding wheel. The drill bit grinding device can test the status of the drill bit without moving the specific position of the outer side of the grinding wheel after grinding the drill bit, and can improve the work efficiency and grinding accuracy of the drill bit edge, thereby reducing the production costs.

Description

technical field

[0001] The invention relates to drill bit processing equipment, in particular to a drill bit grinding device and a detection method which can improve working efficiency. Background technique

[0002] At present, in the preparation process of circuit boards, circuit boards such as main boards, memory cards, and display cards generally need to be drilled with a drill to realize circuit connection. The drill bits used for drilling circuit boards need to be ground for drilling, and after the grinding of the drill is completed, the quality of the drill will be screened and tested to maintain good drilling precision and reduce the cost of the circuit board. Probability of scrapping due to abnormal drilling.

[0003] Before grinding the drill bit, the drill bit grinding device in the prior art needs to move the drill bit in parallel to the open detection position outside the grinding wheel, first determine the length and angle, and then move the drill bit parallel ...
