Conventional ball or cardanic joints, used for positioning vacuum cups flat to a surface have no locking mechanism to hold the desired position. Simmatic have released the new Vtec Valock system which uses a linear level compensator and cardanic joint that lock in position as vacuum is created in the system. This allows the gripper to hold a given form or shape under vacuum, reducing tear on vacuum cups and gives flexibilty of multiple tool or gripper assemblies with just one fixture.
