Dual-sided Electronic Control Permanent Magnetic Suction Disc Design Optimization And Research

An electrically controlled permanent magnet suction cup that uses high-performance magnetic materials with strong adsorption force and high reliability is suitable for various industrial fields such as machinery,transportation,and lifting.To broaden the application scope of electrically controlled permanent magnet suction cups,a new type of dual-sided electrically controlled permanent magnet suction cup is designed and developed,which can generate magnetic attraction force on both sides simultaneously,achieving high working efficiency.The two working surfaces of the suction cup can either be simultaneously magnetized or demagnetized,or one side can be magnetized while the other is demagnetized to meet the needs of different industries.Developing a new type of suction cup plays a positive role in improving the company’s innovative capabilities and rapid market response capabilities.To meet the demand for multi-surface suction cups in actual production,this paper focuses on the design optimization of parallel dual-sided electrically controlled permanent magnet suction cups and related issues and conducts research on the following main topics:The dual-sided electrically-controlled permanent magnet chuck adopts a new magnetic circuit structure and selects materials for each component.Based on the given magnetic suction force and combined with material properties,the dimensional parameters of each component of the chuck are calculated.The working principle of the chuck is analyzed under two states:simultaneous magnetization and demagnetization on both sides,and magnetization on one side and demagnetization on the other.Establish a two-pole unit suction cup model and use finite element software to simulate and analyze the simultaneous magnetization and demagnetization effects on both working surfaces.In the fully magnetized and demagnetized states,the magnetic attraction forces on both working surfaces are equal,and the suction cup is capable of demagnetization.Simulation results demonstrate the magnetization and demagnetization states of the two working surfaces can be interchanged,and the magnetic attraction forces are comparable to those obtained when both working surfaces are magnetized and demagnetized simultaneously.A comparison with a single working surface suction cup shows a decrease of approximately 4.5%in magnetic attraction force during magnetization and an improvement of approximately 4.7%in demagnetization performance for the double working surface suction cup,thus verifying the rationality and feasibility of the double working surface magnetic pole unit design.The temperature field analysis of the double working surface suction cup indicates that it can reliably operate under frequent magnetization and demagnetization working conditions.Under the working condition of magnetization on one side and demagnetization on the other of the dual-sided chuck,with the maximum magnetic suction force during magnetization and the minimum magnetic suction force during demagnetization as optimization objectives,the variable screening method is used to determine the correlation between the position and size parameters and the magnetic suction force.Then,the response surface method is used to perform multi-objective optimization on the variables with high influence.Compared to the initial dimensions,the optimized chuck has an improvement of about 24%in magnetization and about 34%in demagnetization.A dual-sided chuck with two-pole units was developed and tested for magnetization and demagnetization.The magnetic suction force of the dual-sided chuck during magnetization was measured to be 307kg/100cm~2,and the demagnetization magnetic suction force was 10.1kg/100cm~2.The difference in magnetic suction force between the upper and lower sides was within 1%.The experiment confirmed that the dual-sided chuck met the design requirements.
