Robot
Disclosed is a robot which is compact in structure and may be movable in a large working range, wherein move members 1, 1 may be moved by drive devices 4, 4 respectively along a straight line and in parallel with each other, the drive devices 4, 4 including motors 40, 40 respectively which are individually controlled by a control device 9 , so that the move members 1, 1 may be moved at a different speed and may be stopped at different relative positions. The move members 1, 1 are connected to a work holder 3 by means of arms 2, 2 , the arms having one end pivotally connected to the move members 1, 1 at the pivots 10, 10 thereof respectively, the arms 2, 2 having the opposite end pivotally connected to the work holder 3 at the pivots 30, 30 thereof respectively. The work holder 3 may hold an optional jig and may be moved in a horizontal plane and in a vertical plane enabling the jig to work in the working plane.
1. A robot comprising:
two move members which are arranged as being movable in a plane along different lines;
at least two links, each of which has one end pivotally connected to a respective one of said move members and the length of said two links is variable;
a work holder pivotally connected to the opposite end of each of said links;
drive means for independently driving said move members;
control means for controlling the operation of said drive means; and amplifying means for amplifying the drive distance of said move members which are driven by said drive means.
2. A robot comprising:
two move members which are arranged as being movable in a plane along different lines;
first links, each of which having one end pivotally connected to a respective one of said move members;
a work holder pivotally connected to the opposite end of each of said first links;
a second link arranged in parallel with at least one of said first links and one end of which is connected to said move member and the other of which is connected to said work holder;
drive means for independently driving said move members;
control means for controlling the operation of said drive means, and
an amplifying means for amplifying the drive distance of said move members which are driven by said drive means.
3. A robot comprising:
two move members which are arranged as being movable in a plane along different lines;
first links, each of which having one end pivotally connected to a respective one of said move members;
a work holder pivotally connected to the opposite end of each of said first links;
a second link arranged in parallel with at least one of said first links and one end of which is connected to said move member and the other of which is connected to said work holder;
drive means for independently driving said move members;
control means for controlling the operation of said drive means,
wherein said move members are moved in paths that are not in parallel with each other.
4. The robot as defined in claim 1 , wherein said move members are mounted on a movable member movable in the X-Y direction.
