Researching Of Directional Assembling Of Chain Sleeve Using Optical Recognition

This paper firstly proposes the use of technology of optical identification in the directional assembling of sleeve and the using of optical, mechanical and electronic integration, and it has get some success. Optical, mechanical and electronic integration is a high and new technology by using photoelectron on the base of mechanical and electronic integration and a modern mechanical system of fine mechanics, optics, electronic, cybernation and computer. It is not only a developing orientation of the mechanical industry in epoch of knowledge economy but also has brought out a technological reformation ranging of the whole world. If it is said that 20 century is a century of micro-electronics, 21st century can be considered as a century of photoelectron.. USDC once pointed out that the one that gain initiative in the industry of photoelectron will win in the advanced technology of 21st century. Optical, mechanical and electronic integration is a high and new technology by using photoelectron on the base of mechanical and electronic integration. Nowadays, it is just starting to expand and all the countries pay much attention, including our country, many of which have established the high technology park of optical, mechanical and electronic integration. The chain is a traditional mechanical part with thousands of years' history, but the absorbing of optical, mechanical and electronic integration breathes new life in the developing of chain.Directional assembling of sleeve is an important method to improve the quality of chain. This paper introduces its present use in and out of the country, proposingthe new researching orientation-optical identification, and analyzes the realisticsituation of assembly line in the country , and finishing assembling of sleeve in the course of shipping the raw material to facilitate the use in practice and popularize this technique. It indicates the researches of optical identification have much value and meaning in the theory and practice of optical identification.This paper briefly introduces the developing history of chain, and states its basic structure, and the characteristic of chain transmission compared with toothed gearing and tape drive.. Moreover, it further point out its main forms of losing effectiveness in the practice.Optical identification is a part of optical, mechanical and electronic integration. By the use of advanced photoelectric sensor make machine have the sense of sight. This paper simply introduces the basic theory and concrete structure of photoelectric detecting and the systematic component and characteristics of optical, mechanical and electronic integration.This paper analyzes the main component, monolithic construction and working theory from the entirety to part. As a device of optical, mechanical and electronic integration, the paper introduces its frame construction in detail, the choice of photoelectric sensor and chain transmission, the use of controlling chip, the designing of electronic circuit and the compiling of controlling software, and proposes the further researching direction. The experiment chooses optical fibre sensor which has the features of small space to take, accurate to distinguish and convenient to use as one of the the fastest developing in present. While, the magnetic stepping motor is choosed , because it can position accurately and control conveniently. It is widely used in the field of controlling.The main way of losing effectiveness of the chain is abrasion. Research shows that the position of assembling of sleeve affects the mar proof. The use of mechanical means of distinguishing the seam of sleeves to complete direction is limited by the assembly line in our country. Therefore directional assembling of sleeve is not popularized widely in our country and the level of the chain's quality is impacted very much. Taking the theory of electrooptical technology as basis, the paper propose the new orientation of optical identification by the use of non-touching ways to finish the identification of sleeves. Controlled by the chip, the whole system becomes optical, mechanical and electronic intelligence system to realize the intelligent and fully automatical work. The device can finish directional assembling of sleeves quickly and correctly, and it can be used in the chain's assembly line conveniently domestically because of its configuration. So it lays the first stone in the further practice.There kinds of chain with different position of assembling of sleeve are taken to experiment. Their processing technic shares the common sense. One has the seam inside, that is out of the pressure zone; another has the seam outside, that is in the pressure zone; the third one is installed randomly. Take them to assemble a whole one and put it to LS910 close force stream experimental bench to experimentize. In the 400 hours of experiment, tripping out the affect by the factors such as initial error and the changing of temperature, the chain of sleeve's joint to in has the best abrasive resistance, the second is the chain of stochastic sleeve's joint , the chain of sleeve's joint to out is the worst. As a result, it proves that the position of seam of sleeves affect the chain's abrasive resistance. When the seam is out of the pressure zone, its abrasive resistance will be improved much more.
