The standardization of the boring cemented carbide bit of printed circuit board is stipulated (seeing IPC-DR-570) to the physical dimension and the form and position tolerance of various model drill bits.The error or the defective of two main cutting edge faces of drill bit geometric configuration have also been concluded the industry regulation.But because parameter is numerous, very low in the efficient of microscopically tool using manual measurement, and precision is not high, also is subjected to the influence of people's subjective judgement.
Recently the various automatic bit face detecting instrument that occurs based on the method for Digital Image Processing, is analyzed the bit face image of taking, and obtains its geometric parameter automatically, compares with standard again, and it is qualified to judge whether.But following three problems of ubiquity all: measuring accuracy is not high, is to guarantee processing speed, and most drill point detector all adopts less resolution, though improved computing velocity, is that measurement accuracy descends yet; Strict to picture quality, because the reflective characteristic of the second sword face of drill bit, make its imaging form very big interference to the first sword face, need design and complicated illuminator thereof to suppress to disturb, and the drill point angle difference of different drill bits, the drill bit to different batches in the use also needs the artificial illuminator of adjusting; The restriction of drill-shape is too many, and only the drill bit at particular shape characteristics detects, and will guarantee that the position is in predefined zone, and this proposes higher requirement to the Machine Design of positioning system again.
In sum, prior art all can not solve precision and the flexibility problem that occurs in drill point sword face detects automatically.
