PORTABLE GRAVITY COMPENSATOR CHECKING EQUIPMENT FOR SERIAL TYPE INDUSTRIAL ROBOT ARM

摘要

An apparatus for checking a portable gravity compensator of a robot arm of industrial serial type is provided to check damage of an inner structure of the gravity compensator without separation and decomposition. An apparatus for checking a portable gravity compensator of a robot arm of industrial serial type includes a gravity compensator connected to a first arm through a knuckle(7). The knuckle connects an indicator as a wire(11). The indicator displays a measured information in real time. The indicator is connected to a personal computer(10) to output the information graphed by the personal computer. The indicator stores the output information and compares the output information. When the arm of the robot and the gravity compensator operate circularly, the strain gage located in the knuckle measures a load of a spring and the measured information is displayed through the indicator in real time. The information displayed by the indicator is stored in a database as well.
