Abstract:
The invention relates to a tool flange (1 ) arranged on an arm of an industrial robot for connecting a tool to the arm. The tool flange (1 ) comprises a body (2) having a primary surface (3) adapted to connect to the tool. Further, the tool flange (1 ) comprises a protrusion (5) projecting from the primary surface (3), and arranged to engage with a recess arranged in the tool to provide rotational alignment between the tool and the tool flange (1 ). The tool flange (1 ) is provided with a through-hole stretching through the protrusion (5) and the body (2), and adapted to receive a tube (8) arranged for distributing process media to the tool, and to connect to a corresponding process media connection arranged on the tool.
Abstract:
The invention relates to an industrial robot having a plurality of frame parts (1-7) that are movable in relation to each other and a plurality of joints (8-13). The joints include pivot joints (8-13) providing a pivotal movement around joint axes (A1-A6) that are connected by the respective pivot joint (8-13). At least one of said pivot joints (8-13) is unitarily driven by first and second drive means. Each drive means includes a motor (21a, 21b, 31a, 31b) and a gearbox (22a, 22b, 32a, 32b). The drive means are arranged to solely actuate movement around a single joint axis (A2, A3). According to the invention the first and the second drive means are arranged symmetrically in relation to a plane perpendicular to the joint axis (A2, A3) in order to mitigate the problem of uneven heat distribution at the respective joint.
Abstract:
The invention relates to a system for electrically connecting a tool to a robot wrist. The system includes a first component being a tool flange (5) arranged for rotation around a robot axis, and a second component, which includes an electric cabling and a connector (23) permanently connected to each other. The connector (23) has a plurality of poles (21) and the electric cabling includes a plurality of conductors. Each conductor is permanently connected to a respective pole (21). The tool flange (5) and the connector (23) are mutually adapted for attaching the connector (23) to the tool flange (5). According to the invention the tool flange (5) has eccentric mounting means (29a, 29b) arranged for eccentric attachment of the connector (23) on the tool flange (5). The invention also relates to the components of the system, to a wrist including the system and to an industrial robot provided with such a wrist. The invention also relates to a method for establishing electric connection through a plurality of conductors to a tool flange of a wrist of an industrial robot. The method is based on the use of a system according to the invention.
Abstract:
The invention relates to a robot part (1, 2) such as a robot arm or a robot joint, surrounded by an impact absorbing structure. According to the invention, the impact absorbing structure has a shroud (3) surrounding the robot part (1, 2). The shroud (3) is mounted on two spacing elements (6, 8) such that an interspace is formed between the shroud (3) and the robot part (1, 2). At least one of the spacing elements (6, 8) mounts the shroud (3) elastically. The invention also relates to a method of protecting a robot part by providing the robot part with an impact absorbing structure according to the invention.
Abstract:
The invention relates to an industrial robot having two arms (1, 2). According to the invention at least one of the arms includes abutment means (11, 12) arranged to abut the other arm.
Abstract:
A component feeder (100) comprises a distributer for distributing components (20) from a bulk storage on a pick surface (10), and a retaining wall (40) preventing the components (20) from escaping the pick surface (10). The retaining wall (40) is flexible such that it deforms when a force is applied on it, and it assumes its original shape when the force is no longer applied. The flexible retaining wall (40) allows a robot gripper (30) to push the retaining wall (40) aside when picking a component (20) close to the retaining wall (40).
Abstract:
An industrial robot comprises a collapsible process force applicator 200 with a housing 210, a tip 320, and a biasing mechanism for keeping the tip 320 in a first position in relation to the housing 210. For safety reasons, the tip 320 is configured to move away from the first position when a predetermined force on the tip 320 is exceeded. The collapsible process force applicator 200 is mounted downstream from the last axis, and it is positioned such that its actuation does not occasion a torque on the wrist axes of the robot.
Abstract:
The present invention relates to an industrial robot with at least one arm section mechanically connected to a robot body. A safety coupling (5) is provided between at least the distal part (102b) of the arm section and the rotor body. According to the invention the safety coupling (5) is a magnetic coupling.
Abstract:
A component feeder (10) comprises a lift (50) for elevating a selection of components (30) from a bulk storage, and a pick surface (100) adjacent to the lift (50) for receiving the selection of components (30). A spreader (80) gives the selection of components (30) a push for spreading the selection of components (30) from the lift (50) on the pick surface (100). The combination of a vertical lift (50) and a separate pick surface (100) adjacent to the lift (50) enables the bulk storage being positioned right below the pick surface (100). The area of the pick surface (100) is large in relation to the total footprint of the component feeder (10).
Abstract:
The invention relates to a robot wrist (2) including an inner wrist part (6) and at least one manoeuvre connection means (12, 13). According to the invention, the inner wrist part (6) includes solid-shaft transmission components. The wrist further includes an outer shroud (8a, 8b). The manoeuvre connection means (12, 13) is arranged inside the outer shroud (8a, 8b). The invention also relates to an industrial robot (101) including such a wrist.
