Automatic drilling method for needle tails through image recognition

Abstract

The invention relates to an automatic drilling method for needle tails through image recognition. The method comprises the following steps of: clamping and positioning a group of needles on a clamp; performing image acquisition on distribution and positions of the needle tails by using a camera; transmitting and inputting an image into a computer for automatic recognition and processing to acquire a circle center coordinate point of each needle tail end; transmitting data of all circle center coordinate points to a drilling servo control system; aligning the position of each circle center coordinate point in turn and drilling; cleaning workpieces after the complete drilling operation is finished; performing the image acquisition again; and detecting whether the drilled holes are qualified or not. In the method, a plurality of needles are clamped and processed one time, and an electronic recognition and positioning system of the image can be automatically and accurately positioned to the centers of circles of the needles, so that the processing accuracy and the working efficiency are effectively improved and the rejection rate is reduced; and the method is scientific, rational and accurate, and mass production is realized.

Description

Image Recognition Needle Tail Automatic Drilling Method technical field The invention relates to a drilling method, in particular to an image recognition needle tail automatic drilling method. It is used to automatically identify and drill micro-holes at the tail of needle products. Background technique Existing medical suture needles include a needle body, the front end of the needle body is a needle point, the rear end is a needle tail, and a longitudinal central hole is processed on the end surface of the needle tail. To clamp and secure the suture. The end of the suture is inserted into the tail hole of the needle, and the end of the suture is combined with the needle body by pressing. The existing processing methods of the needle tail hole include drilling with a drill bit, laser processing, and electric discharge machining. Drilling with a drill is generally a single needle clamping, positioning, drilling, cleaning, and inspection. Because only one needle can be ...
