Problems solved by technology

However, due to its structure and its resulting space requirement, such a Delta robot cannot, for example, be used for lateral integration into a press or similar device in order to grasp objects produced or processed by the device and to move to another location

Embodiment Construction

[0020] exist figure 1 A perspective view of an articulated arm robot, generally indicated at 10, is shown in , having a base 12, a first robot arm 14 rotatably arranged on the base about a first axis of rotation A, and A second robot arm 16 is arranged rotatably about a second axis of rotation B on a robot arm 14 . On the free front end of the second robot arm 16 there is an interface 18 for the modular mounting of a tool not shown here, which can be, for example, a gripper or a suction head, and which can be swiveled about a third axis of rotation And / or move along the lifting axis.

[0021] In the illustrated exemplary embodiment, the first axis of rotation A and the second axis of rotation B extend parallel to one another. Due to the similarity to a human arm, the first robot arm 14 is also called the upper arm and the second robot arm 16 is called the lower arm.

[0022] The base 12 by which the articulated arm robot 10 is fixed, for example on a wall or on a support fr...

Abstract

The invention relates to a joint arm robot (10) comprising a base (12), a first robot arm (14) disposed at the base pivotable about a first rotation axis (A) and a second robot arm (16) disposed at the first robot arm (14) pivotable about a second rotation axis (B), wherein the first rotation axis (A) and the second rotation axis (B) are at least approximately parallel to one another, and a first drive motor (24) for moving the first robot arm (14) and the second robot arm (16) about the first rotation axis (A), and a second drive motor (30) for moving the second robot arm (16) about the second rotation axis (B). To improve the dynamic behavior while at the same time maintaining positional accuracy, the base (12) has a U-shaped structure (19) with an upper shoulder (20) and a lower shoulder (22) for pivotable mounting of the first robot arm (14), the first drive motor (24) and the second drive motor (30) are fastened to the base (12) and disposed one behind the other relative to the first robot arm (14) and finally the first drive motor (24) causes a non-traction driving about the first rotation axis (A), whereas the second drive motor (30) acts on the second robot arm (16) by way of a traction gear having a transmission ratio in the range of 1:1 to 30:1.

Description

technical field [0001] The invention relates to an articulated arm robot having a base on which a first robot arm is pivotably arranged about a first axis of rotation and on which a first robot arm is pivotably arranged about a second axis of rotation. A second robot arm is provided, wherein the first axis of rotation and the second axis of rotation are at least approximately parallel to each other, and, in addition, the articulated arm robot has a mechanism for rotating the first robot arm and the second robot arm about the first A first drive motor for moving the axis, and a second drive motor for moving the second robotic arm about a second axis of rotation. Articulated arm robots of this type are known, for example, from US 4,392,776 and US 4,557,662. Background technique [0002] An articulated-arm robot as described above is also called a SCARA robot and is used to move a tool fastened to the free end of a second robot arm in different directions in order to thereby p...
