摘　　要：LED晶片支架是一种网格铝材支架,在移动焊接过程当中容易受力变形,所需夹紧力不大,利用电磁铁作为动力源在夹紧设备上应用具有响应快、安全系数高和成本低等优点,在支架移送装置中设计了一种旋转式磁铁吸力机构,基于麦克斯韦理论,建立了LED支架在移送过程中磁铁夹紧力的数学模型,由于支架在移送过程中受到焊接温度、移动速度等的影响,需要动态调整夹紧力,设计的磁力夹紧装置通过实验测试验证,工作平稳可靠,具有一定的应用价值。The LED wafer stent is a grid aluminium frame, in the mobile welding process which is easy to deformation, not required clamping force, the electromagnet as a power source in the clamping device with fast response, high safety and low cost, in stent transfer device design in a rotary magnet suction mechanism based on Maxwell theory, established the mathematical model of LED support in the process of clamping force to the magnet, the bracket by welding temperature in the transfer process, moving speed, the clamping force should be adjusted dynamically, design of the magnetic clamping device is validated by experiments, stable and reliable work, have a certain application value.
