Design And Analyse Of Directional Assembling Of Roller Chain Sleeve Based On Labview

Orientation of the sleeve roller chain assembly through the Lab VIEW software is proposed in this paper for the first time. Through the software a macaronis system with a fast and reliable image processing host, the median responding and implementing the control procedures and the lower one implementing and directing the process of loading and unloading was established; the desired effect was achieved. Integration technology is the integrated use of various types of knowledge and it is characterized by the strong power of mutually benefit and complementary defects in production practice. Electromechanical integration technology is one important branches of today's integration technology. The introduction of optical makes it one of the most popular and promising high-techs. Electromechanical integration technology compromises mechanical, electronic circuits, control theory, computer technology, optical and other integrated disciplines. This technology opens up a new era in the mechanical field and it is the direction of the development of machinery industry. Electromechanical integration technology has set off a new round of technological revolution around the world; if the last time is the era of microelectronics, now it is not only the era of optical integration but also era of electromechanical integration.Electromechanical integration technology attracts the attention of all over the world by its comprehensive advantages and the whole world are developing electromechanical integration technologies and applying new products of this. China has also paid enough attention to this kind of and set up electronic industrial parks throughout the country so as to create multiple incubators for mechanical and electrical integration technology. The chain as the most common and traditional transmission components still needs innovation in the structure, new technology in production and assembly. It is no doubt that the chain will gain new vitality and more sustainable competitive advantage through the use of electromechanical integration technology in the assembly of the chain into the sleeve.Virtual instrument technology is the future trend of industrial development its most unique advantage is not the real instruments but the function of the virtual instrument. This technology assembles required instruments according to production needs without the creating real instruments. Virtual instrument technology depends on the computer support, particularly the virtual instrument software, which is able to build a virtual instrument. Lab VIEW is a powerful proprietary software for virtual instrument; it has been widely used by virtue of its operational flexibility, rich content and wide fields covering. According to depth research based on the chain, it is found that the sleeve gap's direction affects the life of the chain directly and it is one of the key factors of the chain's quality. In order to grasp the quality of the chain we designed the sleeve directional systems in this paper and according to the current national chain sleeve assembly process determined the identification and location of the sleeve, facilitated the chain production.This paper briefly introduces the basic concepts of the chain, describes the application and development of today's chain, playing a significant role in drive. Meanwhile, the paper tries to break through, introduces virtual instruments and the sleeve orientation technologies with the combination of mechanical and electrical integration and the basic related knowledge, such as microcontrollers, Lab VIEW, etc. The optical part applies the virtual instrument technology, the camera and the Lab VIEW software combination, designing a visual, intuitive inspection system; in the mechanical and electrical systems, through the control of the implementation of SCM, so that each is expected to be operative in accordance with the operation of loading and unloading and orientation. We can say that the optical combination of electrical integration and virtual instruments in this design highlights their advantages, makes the advantages of the system a good play.In this paper, the structure of the sleeve-orientated device fully considered the motion requirements, precision requirements and volume-weight requirements, and analyzed the basic working principles of the system. We introduce the composition of the mechanical structure in detail, the scanning position of camera and the motion style of the driving wheel and driven wheel, the selection of motor, the selection of MCU, PCB designing, the main program and subroutines framework of LabVIEW image processing, Modbus communication mode, etc. And the basic project of design is introduced in detail. The combination of LabVIEW and camera made the whole system intuitive and visual, and they constituted the so-called virtual instrument, namely camera detection system. Through 3D stereoscopic imaging, the image is clearer, at the same time processing precision is more accurate, and miscalculation caused by transducer won't appear. Actuator power components used stepping motor, this is because step-motor can accurately position, no accumulated error, convenient to control, and it is popular in the market, so it is easy to gain.Chain has many kinds of failure form, and the most common one is wear and fatigue. After the study, we found that chain sleeve toward in the sleeve assembly process directly affects the lifespan of chain. But in orientation means, in the past we usually adopt mechanical approaches. But this way to confirm the aperture in production assembly process is affected by many aspects of restrictions, so this assembly technology has not been promoted that caused chain sleeve had different lifespan, and the quality was not guaranteed. This design pays attention to non-contact recognition, through LabVIEW we read, storage and processing images, and through serial communication we dictate the transfer to microcontroller, MCU execute operation according to PC control command, thus realize non-contact orientation. Equipment in the testing phase has a high speed, and the sleeve fit the present domestic chain assembly production processes, and lay a solid foundation for realizing the commercialization.This paper does contrast tests on different kinds of sleeve, the main form are as follows: sleeve aperture gaps toward inside, sleeve toward the lateral and sleeve random put, these three chains were tested in the same conditions. In addition to the direction, the manufacturing and assembly of these chains should keep the same. We put the three chains in LS910 test stand to do experiments, the test time is 400 hours. If we don't consider the measurement error and the influence of temperature, the conclusion is as follows: the wear resistance of sleeve inside chain is the best, while sleeve outside chain is the worst. Therefore, in actual use toward of sleeve aperture of the chain has a direct impact on the quality, and it is very meaningful to do research and design on the chain sleeve, and this design will greatly improve the lifespan of chain.
