| Mobile phone is a modern people's lives necessities. In the past 10 years, all manufacturers of cell phone are trying to combine with different cell phone modeling,materials technology and structure. In order to increase the competitive ability of cell phone in the market, it requires control the key technology made the shell of cell phone—the manufacturing costs and development cycle of the molds. Base on RP/RT, the shell manufacturing technology of cell phone is simple, there is no need for the traditional mechanical processing. From the design and manufacture of product to entering the market, the development cycle is greatly reduced, which is an important direction of cell phone modern manufacture.In this paper, we set up the RP / RT integrated manufacturing system of the cell phone production. Firstly, according to cell phone design requirement, traditional experience of cell phone design and rapid prototyping process requirements, established a simple 3-D model of cell phone; Secondly using rapid prototyping technology (SLA) made a cell phone RP prototype. In order to improve the RP prototype accuracy, mainly reduce total area of level ,total area of deformation characteristics ,total area of The curing and parts production time to the least, using which to make the best production direction; then produced a cell phone silicon rubber die; at the last based on comprehensive and systematic study of the RP / RT integrated manufacturing system each link's manufacture error and its control method, taking into account each link error's cumulative effect, the accumulated error will feed back according to a closed loop pattern to the three-dimensional model design input end for error compensation.Based on RP / RT integrated manufacturing system, the problems of shell manufacturing of cell phone in traditional methods are solved, the development cycle is greatly reduced, the manufacturing flexibility is improved, which provides certain guiding significance for the shell rapid manufacturing of cell phone. |
