[Problem] To propose a negative pressure suction seal: in which a free end part does not tear off and a negative pressure suction function is not lost even if the negative pressure suction seal encounters a projection on an object surface; and which can reduce frictional force between the free end part and the object surface. [Solution] The negative pressure suction seal of the present invention is constituted by: a seal fixing part; a seal expanding/contracting part connected to the seal fixing part; and a seal free end part connected to the seal expanding/contracting part. The seal expanding/contracting part is constituted by a portion that becomes narrow, approaching the object surface, from a portion connected to an inner edge of the seal fixing part. The seal free end part is constituted by a portion that expands further outward from the inner edge connected to the seal expanding/contracting part. The seal fixing part is fixed to a suction frame via a seal fixing plate member, and the position of an inner edge of the seal fixing plate member is outward of the position of the inner edge of the seal fixing part. Frictional force between the negative pressure suction seal and the object surface is adjusted by increasing or decreasing the surface area where the seal fixing plate member presses upon the seal fixing part.
本发明的负压吸附密封件即使与位于物体表面的突起相遇自由端部也不翻卷以不丧失负压吸附功能,还可降低自由端部与物体表面的摩擦力。负压吸附密封件由密封件固定部、与密封件固定部连结的密封件伸缩部、与密封件伸缩部连结的密封件自由端部构成,密封件伸缩部由随着从与密封件固定部的内缘部连结的部分起接近物体表面而变窄的部分构成,密封件自由端部由从与密封件伸缩部连结的内缘部起进一步向外侧扩展的部分构成,密封件固定部经由密封件固定板部件固定于吸盘框架,密封件固定板部件的内缘部位于密封件固定部的内缘部的外侧,通过使密封件固定板部件按压密封件固定部的面积增减来调整负压吸附密封件与物体表面的摩擦力。
