1. A component transferring system for a vehicle assembly line, comprising:
a carriage unit operated in response to an electrical signal from a controller to move along the vehicle assembly line,
wherein the carriage unit includes a carriage frame and cylinder units andwherein each of the cylinder units is disposed at a front side and a rear side of the carriage unit respectively and moves up and down; a conveyor disposed along a moving route of the carriage unit; a carriage lifting unit disposed inside of the conveyor in at least one area of the vehicle assembly line, separated from the carriage unit, and moving an object loaded on the carriage unit to the conveyor according to an electrical signal from the controller; a guide sensor disposed at a center section of a lower surface of the carriage frame between operating wheels to detect the moving route of the carriage unit; mark sensors each of which is disposed at each of a rear side and a front side of a bottom surface of the carriage frame with respect to the guide sensor to detect deceleration, acceleration and stop position of the carriage unit; and detecting sensors disposed at a front side and a rear side of the carriage frame to detect obstacles using an ultrasonic wave, wherein the operating wheels are mounted at left and right sides of the center section of the lower surface of the carriage frame and are operated according to the electrical signal from the controller and casters are mounted at the front side and the rear side of the carriage frame, and wherein the controller is mounted inside the carriage frame to control the operating wheels in accordance with detected signals of the guide, mark, and/or detecting sensors, wherein the conveyor is disposed at left and right sides of the carriage unit and a transferring rail is disposed at an upper portion of the conveyor to transfer the object moved by the carriage lifting unit to a predetermined operation line, and wherein the carriage lifting unit includes:
a first cylinder main body disposed at the front side and the rear side of the carriage frame inside the carriage frame in an up and down direction; anda locking pin disposed at a front end of a first operating rod of the first cylinder main body wherein a front end of the locking pin is selectively inserted into a groove formed at a predetermined position of a lower surface of the object;a second cylinder main body disposed at an inside of the conveyor in an up and down direction; anda transferring plate disposed at a front end of a second operating rod of the second cylinder main body to support the lower surface of the object loaded on the carriage unit.
