[Abstract]:It is an effective way to improve product quality, improve production efficiency and reduce labor cost to realize full automatic processing of electronic products. The diaphragm of the loudspeaker is thin and soft and difficult to process. Automatic turntable machine is the key equipment to realize the full automatic processing of diaphragm. In this paper, a kind of automatic turntable machine is designed and optimized for the vibration film processing of mobile phone loudspeaker. The main work of this paper is as follows: the physical characteristics of the diaphragm of the mobile phone speaker are analyzed. According to the process flow of the diaphragm and the process action of the equipment, the overall design scheme of the automatic turntable machine is put forward, and the work flow and process requirements of each part structure are determined. Diaphragm products are flipped, laser-cut and coded by automatic turntable machines. According to the process analysis of each part, SolidWorks is used to design the structure of each part of automatic turntable machine. The rationality of the design is verified by virtual assembly of each organization. The buffers of the initial positioning mechanism in the transmission mechanism of the automatic turntable machine are selected and calculated. The type of controller of electrical control system in automatic turntable machine is selected. The whole scheme of control unit and control system is put forward, and the hardware selection basis of control system is given. The process design of electrical control system is carried out. The coordination of automatic turntable is analyzed, and the cycle of loading and handling is optimized to meet the demand of production. The prototype is assembled and debugged. The working performance of the automatic turntable machine is tested. The test data show that the designed automatic turntable has the advantages of high automation, high production efficiency and stable equipment. Finally, the structure of the automatic turntable mechanism is optimized, and the positioning clamping mechanism of the turntable mechanism is optimized. The optimized positioning clamping mechanism is applied to the vibration film processing equipment, which is helpful to improve the accuracy of the repeated positioning of the turntable and facilitate the debugging of the equipment.
