Abstract
A slave combining with a master in a robot tool changing system is disclosed. The slave includes a combination groove into which a protrusion of the master is inserted, at least one plate displacement measuring module arranged at a circumferential edge of a hole of the combination groove, and a slave communicator for communicating with the master. Accordingly, a robot tool changing system including an artificial intelligence (AI) function and performing 5G communications may be provided.
Claims13
A slave combining with a master in a robot tool changing system, the slave comprising:
- a combination groove into which a protrusion of the master is inserted;
- at least one plate displacement measurer arranged at a circumferential edge of a hole of the combination groove, and including a lower plate, an upper plate arranged in an upper direction to correspond to the lower plate, and at least one elastic connection leg for connecting the upper plate and the lower plate;
- and
- a slave communicator for communicating with the master,
- wherein the upper plate comprises a permanent magnet, and
- wherein, when power is applied to an electromagnet of the master so that the upper plate is moved to a magnetic coupling region of the protrusion by magnetism, the plate displacement measurer transmits, to the master, position error information between the upper plate and the lower plate connected to the upper plate, through the slave communicator.
A master combining with at least one slave in a robot tool changing system, the master comprising:
- a body;
- a protrusion protruding from the body in one direction and which is inserted into a combination groove of a slave;
- at least one fastening part arranged in a predetermined region of the protrusion and fixing the protrusion to the combination groove;
- an electromagnet arranged in a predetermined internal region of the protrusion;
- a master communicator for communicating with the slave;
- and
- a controller,
- wherein, when power is applied to the electromagnet so that upper plates of the slave are moved by magnetism to a magnetic coupling region of the protrusion, the controller controls the master communicator to receive, from the slave, position error information between the upper plates and lower plates of the slave, and
- wherein, when power is applied to the electromagnet and a vertical position error is measured by at least one plate displacement measurer of the slave in a vertical direction of the upper plates of the slave in a predetermined range, the controller receives the position error information in the form of the vertical position error from the slave through the master communicator.
