Abstract
An arm member having a folding expansion/contraction mechanism is fixed to a rotary shaft. A support member is rotatively mounted on the distal end of the arm member. This support member maintains a constant relationship with the rotary shaft. An auxiliary support member is mounted on a support shaft fixed to the support member, the auxiliary support member being able to swing. A cam mechanism is provided at rotation portions of the support member and auxiliary support member. The auxiliary support member is swung by this cam mechanism in accordance with a folding expansion/contraction motion of the arm member.
Claims8
A robotic arm comprising:
- a rotary shaft;
- an articulated arm member fixed to said rotary shaft and having a folding expansion/contraction mechanism;
- a support member rotatively supported by a distal end of said arm member, said folding mechanism being connected between said shaft and said support member for providing a constant relationship between said rotary shaft and said support member;
- an auxiliary support member supported by a support shaft fixed to said support member for supporting a workpiece in cooperation with said support member, said auxiliary support member being swingable an association with a folding expansion/contraction motion of said arm member and
- a cam mechanism provided at portions where said auxiliary support member and said arm member are coupled with each other for swinging said auxiliary support member in association with said folding expansion/contraction motion of said arm member.
