Micro-drill online sorting system

Abstract

The invention relates to the technical field of online detection, and discloses a micro drill online sorting system which comprises an assembly line, a follow fixture, a feeding mechanism, a clamping mechanism, a detection mechanism and a sorting mechanism. A limiting mechanism and a locking mechanism are arranged on the assembly line; the feeding mechanism is responsible for conveying tidily arranged micro drills to the clamping mechanism, the clamping mechanism is responsible for placing the micro drills on the limited follow fixtures located on the assembly line, the detection mechanism is responsible for detecting the follow fixtures and the micro drills on the follow fixtures, and the detected follow fixtures and the detected micro drills are classified through the sorting mechanism; detection and sorting of the semi-finished micro-drills are automatically modified, all the semi-finished micro-drills can be detected online in real time and sorted according to the detection result, then the micro-drills with the sizes exceeding the limit deviation are subjected to size specification series adjustment, if the sizes are qualified, the micro-drills enter the next process, and the production efficiency is improved. Therefore, the detection and the production can be synchronized, and the labor cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of on-line detection, and more specifically relates to an on-line measurement and sorting system for micro-drill production. Background technique [0002] In recent years, the trend of producing "smaller, faster and cheaper" miniaturized products in industries such as electronics, aviation, medicine and automobiles has become increasingly obvious. The production of miniaturized components, such as printed circuit boards (PCBs), micronozzles, micromolds, chemical microreactors, dental implants, high-tech medical appliances, fuel filters, and fuel ignition systems, is all done with the help of micromachining technology of. Drills smaller than Φ3.175mm are usually called micro drills, or micro drills for short. Among them, Φ0.5mm~Φ3.175mm fixed-shank micro-drills made of solid carbide materials are mostly used for drilling PCB boards, and each increase in diameter by 0.05mm is a series of size specifications....

Problems solved by technology

[0004] The CCD measurement system uses the lighting system to uniformly illuminate the object to be measured, and then images it on the linear array CCD through the optical imaging system, and then completes the extraction of diameter information by the data acquisition circuit. This method is characterized by high detection accuracy, but if To obtain two-dimensional images, it must be equipped with a mechanical scanning mechanism and an A / D acquisition card, which not only increases the complexity and cost of the system, but also has a slow detection speed; And the processing algorithm of taking the average value realizes the two-way detection of the thickness and width of the workpiece wire diameter, overcomes the shortcomings of the single-channel laser diameter measuring system such as the limited measurement range, and the accuracy of the diameter measuring instrument can reach 0.001mm, and the indication error does not exceed ±0.005mm, with good stability and high measurement accuracy, it is suitable for the precision detection of small-sized workpiece wire diameters on the production line, but it also has the problem of slow detection speed, that is, neither of them can match the actual production beat, and the micro Drilling accuracy requirements are high, so companies generally use special testing equipment for offline testing, sorting and storing, and then proceed to subsequent processing after a batch of parts are sorted, which leads to higher costs for micro-drilling testing , and even the problem that the detection cost is higher than the production cost
