Abstract
Disclosed is a device for supplying bolts having an improved bolt supply mechanism so as to enhance work speed and productivity as well as to prevent various interferences and troubles caused by driving a robot. The device for supplying bolts comprises a rotary magazine that indexes a plurality of bolts; and a nut runner having a driving bit that picks up a bolt in the rotary magazine one by one and performs a driving operation, wherein the rotary magazine has a turret that houses a plurality of bolts in a circumferential direction and positions a bolt in the nut runner by rotation.
Claims13
A device for supplying bolts, comprising:
- a rotary magazine configured to index a plurality of bolts;
- and
- a nut runner having a driving bit configured to pick up a bolt in the rotary magazine and to perform a driving operation,
- wherein the rotary magazine comprises a turret configured to have a plurality of receiving cavities to house the plurality of bolts in a circumferential direction of the turret and position a bolt in the nut runner by rotation, and a housing configured to at least partially cover upper ends of the plurality of bolts housed in the plurality of receiving cavities,
- wherein the device further comprises:
- a robot module configured to rotate the turret and to transfer the rotary magazine toward the nut runner, and
- wherein the robot module comprises:
- a rotation motor connected to a center hole of the turret and configured to rotate the turret and
- a z-axis transfer unit configured to move the rotation motor in a z-axis direction and transfer the rotary magazine toward the driving bit;
- wherein the robot module further comprises:
- an x-axis transfer unit configured to move the z-axis transfer unit in a direction orthogonal to the z-axis direction and thereby transfer the rotary magazine toward the driving bit.

A method for supplying bolts, comprising:
- configuring a first rotary magazine to receive a plurality of bolts;
- and
- picking up a bolt in the first rotary magazine using a nut runner having a driving bit,
- wherein the first rotary magazine comprises a turret configured to have a plurality of receiving cavities to house the plurality of bolts in a circumferential direction of the turret and position a bolt in the nut runner by rotation, and a housing configured to at least partially cover upper ends of the plurality of bolts housed in the plurality of receiving cavities, the method further comprising:
- moving a second rotary magazine unfilled with bolts and clamping the second rotary magazine unfilled with bolts to a magazine shuttle with which the first rotary magazine is engaged;
- and
- clamping the first rotary magazine with bolts to a robot module configured to rotate the turret;
- wherein the robot module comprises:
- a rotation motor configured to move the turret;
- and
- an x-axis transfer unit configured to move a z-axis transfer unit in a direction orthogonal to a z-axis direction and thereby transferring the first rotary magazine toward the driving bit.
