【摘要】 针对汽车挺柱体自动装配线中人工上料效率低下、达不到要求的生产节拍以及无法保证铜销表面精度等问题,对铜销的自动上料方式进行了研究,对振动料斗上料、皮带机上料、料盒上料以及机械手上料等自动上料方案进行了讨论,选择了一种由料盒、机械手和接放部件组成的铜销自动上料装置设计方案,利用料盒确保铜销在存放时不会相互碰撞并保证反复上料过程的重复定位精度,通过移载机械手实现了铜销抓取以及快速移放,通过旋转接放部件使铜销在重力作用下落入了装配工位。研究结果表明,这一上料装置能够在确保铜销表面精度的要求下,完成了生产线流畅运行,达到了要求的工作节拍,实现了挺柱体铜销的自动上料,提高了生产效率。更多还原

【Abstract】 Aiming at the problem of the inefficient artificial feeding,the production cycle which cannot meet the requirements and the surface finish of the brass pin which cannot be ensured of the automotive valve tappets’ assembly line,an automatic brass pin fitting device was studied. Several automatic feeding schemes such as vibrating hopper,belt conveyor,cartridge and gantry robot were discussed. An automatic feeding scheme consisting of the cartridge,the gantry robot and the receiving and dropping mechanism was chosen. The repetitive positioning accuracy and anti-collision between the pins were guaranteed by the cartridge; the pin grabbed and travelled rapidly were affected by gantry robot; the pin fitted in the right place was completed by the receiving and dropping mechanism which can turn over right-angle to make the pin drop in assembly station by means of its gravity. The results indicate that this device makes the assembly line run smoothly,improves productivity and ensures the surface finish of the brass pin.更多还原
