Research On The Theory And Technology Of Vibratory Feeding Of Seals

In most enterprises, vibratory bowel feeder is an automatic feeding device in the automatic production process. At present, there are mainly two drive modes of vibratory bowel feeder:electromagnetic and piezoelectric driving, in which piezoelectric vibration is developed in recent years. It has wide operating frequency range, low noise, no electromagnetic pollution, convenient adjustment, etc. Compared with piezoelectric vibratory bowel feeder, the electromagnetic vibratory bowel feeder has a strong conveying force, work environment requirements is not high, and relative low production cost and other advantages, which is the cause of electromagnetic vibratory bowel feeder wider range of applications than others.In recent years, due to the state to increase the transformation of the power grid, the demand for electricity meter is very large, and enterprises in the production process are still using manual assembly. After working in a lot of repetitive action, workers’ working efficiency decreased. In order to improve the production efficiency and reduce the labor intensity of workers, we need to change manually install to automatic assembly, and the most critical aspect in automated assembly process is automatic feeding. Therefore, in this paper, we use electromagnetic vibratory bowel feeder to achieve seals feed, to solve the automatic supply in the assembly process of electricity meters.According to an electromagnetic vibratory bowel feeder prototype a general form of kinetic equations is established, the influence of geometric parameters of the plate spring on the steady state response of vibration system is analyzed. Using finite element analysis software ANSYS to analysis the modal and harmonic response of the vibration system. The different external excitation frequency of the system response is obtained.Under the structure optimization design idea, the system natural frequency and the quality of the bowl and the base are set as the goal, the response amplitude of the bowl and the base are set as the evaluation criteria, the geometric parameters of the electromagnetic vibratory bowl feeder is optimized, the optimum design parameters is achieved.The state of motion of seal within the vibration period of the electromagnetic vibratory bowel feeder is analyzed; we obtained the condition of each motion, proposed the best state of motion in delivery process, and further theoretically get the range of orbit inclination angle and vibration angle. Using discrete element method software EDEM to analysis the movement of a large number of seals, to research the influence of feeding speed about orbit inclination angle, amplitude of bowl, and the size of the friction between seals and bowl for the efficient design of the vibratory bowl feeder.The main part of the bowl in electromagnetic vibratory bowel feeder is discussed; the paper introduced the material, type, surface treatment and production process of the bowl. The natural posture probability of seal is studied, we find out the most probable and the most stable natural posture 1.According to characteristics of the natural posture 1 and combined with the existing classical orientation mechanism, corresponding mechanism to select and arrange seals is designed, which can realize automatic supply and improve production efficiency.
