Publication number: 20210260725Abstract: This clamping tool uses optical distance verification with a laser. Clamping tools, like all tools, are known to be operated improperly. Many tools verify process completion by monitoring the pressure within the pneumatic tool. Previous qualifiers use pressure to determine many things. However, it often misses if a small object impedes a full stroke. With the addition of an optical laser sensor, we are able to determine if a clamping tool reaches full stroke.Type: ApplicationFiled: February 5, 2021Publication date: August 26, 2021Applicant: C. E.
