[Abstract]:With the development of industrial production technology and the improvement of scientific research level, mobile phones, computers and other electronic products have been more and more widely used in daily life. And drive the rapid development of its related parts industry. Among the components of this kind of electronic products, the loudspeaker voice coil assembly is small in size and high in accuracy. And it has the characteristic of very high acoustics requirement and has been widely concerned. Under the condition that the production of fully automatic voice coil has some difficulty, It is imperative to develop and develop automatic voice coil production equipment. In this paper, the types and development status of related tangent machine are studied, and the key structure of voice coil tangent machine is analyzed according to customer requirements and combining with the particularity of loudspeaker voice coil. The whole layout design and monitoring system design of the voice coil tangent machine are completed. The transmission mechanism of the voice coil tangent machine is analyzed and designed in this paper. The key parts of the transmission mechanism are calculated and checked to ensure the stability of the transmission mechanism. The key to solve the problem of low efficiency and quality gradient of the voice coil tangent machine is designed in this paper. In this paper, the positioning mode of the voice coil line is analyzed, and the device is designed to ensure the accurate positioning of the voice coil carrier, which is the key structure of the voice coil tangent line. The action process and timing distribution of voice coil wire clamp mechanism are analyzed in detail. The type of clamping mechanism, the size of clamping force and the transfer relation are determined, and the Matlab software is used to simulate the claw transfer function. The PID algorithm is used to improve the system, in order to realize the system monitoring and fault display of the voice coil tangent machine, it is convenient to debug and maintain the equipment. In this paper, the monitoring interface of the voice coil tangent machine system is designed. In order to analyze the performance of the sound coil tangent machine model, this paper adopts the combined technology of ADAMS mechanical dynamics simulation software and Matlab/Simulink control software to carry out the system simulation. According to the simulation results, the control system of voice coil tangent machine is optimized.
