摘要
目的研制一种医用全自动电极打磨装置,用于替代手工或半自动打磨电极,解决电极打磨效果的均一性问题。方法该装置主要由机械臂、夹具、打磨装置、外壳及控制系统构成,使用计算机辅助设计制图及3D打印技术制作成品,并运用电化学的循环伏安法,采用三电极体系进行应用效果评价。结果所磨电极采用电化学的循环伏安法酸扫,在电位0~1.6 V之间不断扫描直至获得稳定的金电极的循环伏安特征峰。得出自动打磨的8根电极Au还原峰数值在0.3~0.35μA,氧化特征峰稳定、均一性好;手动打磨的8根电极Au还原峰数值在0.3~0.7μA,氧化特征峰不稳定、均一性较差。结论该装置实现了电极打磨全过程的自动化,通过精确控制每一根电极的打磨力度、速度、打磨方式及时间,有效解决了手动打磨无法解决的效果均一性问题。
Objective To replace manual or semi-automatic electrode polishing and solve the problem of uniformity of electrode grinding effect by developing a fully automatic electrode grinding device for medical use.Methods The device was mainly composed of mechanical arm,fixture,polishing device,casing,and control system.The finished product was made by using computer-aided drawing and 3D printing technology,and the electrochemical cyclic voltammetry method was used to evaluate the application effect by using a three-electrode system.Results The polished electrode was continuously scanned between 0 and 1.6 V by electrochemical cyclic voltammetry until a stable cyclic voltammetric characteristic peak of the gold electrode was obtained.It was concluded that the Au reduction peak values of the eight electrodes automatically polished were 0.3~0.35μA,and the oxidation characteristic peaks were stable and homogeneous;the Au reduction peak values of the eight manually polished electrodes were 0.3~0.7μA,and the oxidation characteristic peaks were unstable with poor uniformity.Conclusion The device realizes the automation of the whole process of electrode polishing.By accurately controlling the strength,speed,mode and time of electrode polishing,the uniformity of the effect that cannot be solved by manual polishing is effectively solved.
