  • 为解决传统生产中海珍品分拣方式效率低、破损率高的实际问题,以虾夷扇贝(Patinopecten yessoensis)为对象,在对其形态特性、物理特性研究的基础上,研制了一种三指柔性抓取装置,柔性手指呈"A"字型结构,柔性三指张开度Ф为14.66~197.44 mm,并建立柔性手指模型,将虾夷扇贝实体简化为类球体,对柔性单指受力和柔性三指抓取进行仿真分析。结果表明:设计的分拣装置柔性单指受力时向接触面受力一侧弯曲,柔性三指弯曲变形组成完整的包络曲面,包络自适应性能良好;对单一规格虾夷扇贝进行抓取成功率和夹持力试验显示,当气压低于0.2 MPa时,抓取成功率不足90%,当气压达到0.6 MPa时,平均抓取成功率在98%以上,壳体及边缘均无破损,且随着气压的增加,抓取成功率和夹持力均呈正相关变化;在气压为0.6 MPa时,对3种不同质量的虾夷扇贝进行抓取性能试验显示,实测横向、纵向抓取的最大夹持力分别为8.76、7.24 N,虾夷扇贝壳体及边缘无破损,且随着虾夷扇贝质量的增加,夹持力呈下降趋势。研究表明,本研究中所设计的分拣装置能够满足大部分贝类珍品分拣的需求,可应用于规模化生产扇贝、牡蛎、鲍和螺等多种贝类珍品的无损分拣。
