Gripper

Precision assembly gripper for confined spaces combining telescopic legs and suction functionality

This technology features a body member and a pair of sliding leg members, integrating the telescopic function of the first leg with the suction capability of the second leg to create a precision gripping and assembly mechanism.

Conventional multi-jointed grippers are structurally unsuitable for installing electronic components in tight spaces, such as inside small mobile device cases, and relying solely on suction methods often results in poor positioning accuracy.

By combining the telescopic length adjustment of the first leg with the vacuum suction of the second leg, this technology performs a multi-stage gripping operation: it picks up and transports objects with a wide span, then reduces the leg spacing and length while maintaining suction to precisely seat components in confined areas. It can be applied to electronic component assembly, precision manufacturing, and small device automation, enhancing assembly accuracy by precisely positioning parts in tight spaces.

Key Features:

• First and second leg members supported by a body member with adjustable distance between them
• A suction unit on the second leg member for picking up and securing objects, and a telescopic first leg member
• A structure where the leg members are supported by the body member and slide horizontally to adjust the distance between them
• The first leg member includes a support section attached to the body member and a telescopic section that extends and retracts from the support section
