Structure for absorbing positional displacement of an article clamped by robot arms

Abstract

A positional displacement absorbing structure for absorbing the positional displacement of an article 21 clamped by a pair of robot arms 22, 22 is provided. The pair of the robot arms include recesses 32, 33 on their faces 31, 31 opposed to the article. The article 21 includes projections 25, 26 on its side faces 24, 24 opposed to the pair of the robot arms 22, 22. The projections 25, 26 are adapted to be respectively engaged in the recesses 32, 33. Each of the projections 25, 26 is formed with a pair of inclined faces 27, 27, 28, 28 with which circumferential edges 34, 35 of the recesses 32, 33 are adapted to slidably contact.

Dependencies are inferred from the claim text.
