Abstract

In the use of automated manufacturing equipment or robotic equipment, such as the IBM 7535 manufacturing system, Z-axis motion is required to accomplish the work manipulation. At some point during the travel in the Z-axis of the manipulator or gripper shaft 10, impact between the stop plate 12 and the frame 14 of the system occurs. This impact is a detrimental shock which not only may be destructive of the operating members of the manufacturing system but also may act to adversely affect the holding and retaining of parts or assemblies grasped in the gripper or being worked on by any of the other attachments which may be utilized with the robotic system.

Controlled Linear Deceleration for IBM 7535 Manufacturing System

In the use of automated manufacturing equipment or robotic equipment, such as the IBM 7535 manufacturing system, Z-axis motion is required to accomplish the work manipulation. At some point during the travel in the Z-axis of the manipulator or gripper shaft 10, impact between the stop plate 12 and the frame 14 of the system occurs. This impact is a detrimental shock which not only may be destructive of the operating members of the manufacturing system but also may act to adversely affect the holding and retaining of parts or assemblies grasped in the gripper or being worked on by any of the other attachments which may be utilized with the robotic system. In order to control the deceleration of the stop plate 12 and thus the moving mechanism associated therewith, a shock absorber 16 may be adaptively mounted in the stop plate 12 such that the shaft 18 thereof may engage a stop surface 20. The engagement of shaft 18 and stop surface 20 will occur prior to the end of travel such that the deceleration of the stop plate, and thus all the associated moving hardware, may be controlled and thereby reduce destructive impacts. The control of the deceleration may be accomplished by the selection of the shock absorber, and thus a very easy deceleration or an abrupt deceleration may be accomplished while still removing much of the impact shock previously encountered.
