摘要

The disclosure generally relates to unclamp sensing feedback devices for clamping or holding devices in automatic production lines more specifically to a link clamp assembly. Further, the disclosure also provides the method of achieving feedback to sense fully unclamped condition of the link clamp cylinder.

主权项

1. An unclamp feedback unit for a link clamp cylinder, the unclamp feedback unit comprising a pivot pin, a spring loaded piston and a pneumatic input unit; wherein a clamp lever pivots freely between orientation elements; the orientation elements being separated by a predetermined distance, and extending vertically from a flat base of at least one bracket and wherein the clamp lever is pivoted by one end of the pivot pin, and wherein an opposite end of the pivot pin is fixed to a feedback unit of a link clamp assembly; wherein, upon actuation, one end of the spring loaded piston contacts a plate of the link clamp assembly, and the spring loaded piston is pressed inwards into a pneumatic check line of the pneumatic input unit, thereby causing a change of pressure of air flow in the pneumatic check line.
