Embodiment Construction

[0045] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0046] figure 1 It is a schematic configuration diagram of a vehicle production system using a collaborative robot according to an embodiment of the present invention.

[0047] refer to figure 1 , the vehicle production system using a collaborative robot includes: a bumper 100, a car body 110, and a collaborative robot 120, and the collaborative robot 120 includes a multi-joint arm 124, a gripper 200, a weight compensation device 130, an F / T sensor 122, a proximity sensor 126 , a drive unit 128 and a control unit 140 .

[0048] The gripper 200 is mounted on one end of the multi-joint arm 124, and the drive unit 128 changes the position and rotation position of the gripper 200 in three-dimensional space through the multi-joint arm 124, and drives the gripper. The tool 200 is used to grab the above-mentioned bumper 100 .

Abstract

A cooperation robot for moving a bumper to a predetermined position of a vehicle in a vehicle production system includes: a multi-axis arm, a front end portion of which is connected to and a rear end portion of which is connected to a robot body so that the multi-axis arm is movably disposed to upper, lower, left and right sides on the basis of the robot body. The multi-axis arm is disposed to rotate the gripper. A force torque (FT) sensor is disposed between the multi-axis arm and the gripper and detects a direction of external force which is applied to the gripper and the bumper gripped by the gripper. An operator controls the multi-axis arm so that positions of the gripper and the bumper vary. A controller controls the operator according to the direction of the external force detected by the FT sensor when the multi-axis arm is in a stand-by condition to move the gripper in the direction the external force.

Description

technical field [0001] The present invention relates to a vehicle production system using a collaborative robot, and specifically relates to a vehicle production system and a production method using a collaborative robot as follows: grabbing a bumper and moving the bumper to a set position of the vehicle body, capable of interacting with The operator cooperates to easily attach the bumper to the vehicle body. Background technique [0002] Due to the aging of industrial manufacturing sites, simple repetitive operations and tiring operations will increase the risk of musculoskeletal diseases. Therefore, as an alternative, collaborative robots that can assist operators are gradually gaining attention. [0003] The process of attaching the trunk lid hinge to the vehicle body requires repeated operations, which may cause injury to the operator's wrists. In order to reduce this problem, labor-saving equipment of the counterweight type is used. [0004] However, it is difficult to...
