The present invention relates to a multi-axis unit device and a system. One embodiment of the present invention may be a multi-axle unit device and system for bogies in an automobile production process that includes a telescopic structure with a screw and an impact absorbing member and includes a wire inside the device.

Typically, from automobile makers to automobiles, 20,000 to 30,000 parts are assembled through a number of welding and assembly processes within every mass-production plant.

In the production line of such a vehicle, its components perform the corresponding processes through a lane system.

In the conventional conveyance truck system, the bogie simply moves to each assembly line along the rail in response to the driving of the motor, stops at a predetermined position, and then moves to the next step. There is a problem that efficiency of assembling work is greatly deteriorated because the structure can not be freely adjusted according to the size, height, or the physical condition of the worker, and the fatigue of the worker is increased.

Further, the complicated cable bearer is located outside, and electric wires and motors are disposed outside the device, so that the electric wires and the motor are not protected from the external environment, and such a configuration enlarges the entire device volume.

Further, it is not provided with any shock absorbing member, and is vulnerable to the impact on the weight of the car being transported.

In the automobile parts production line, the platform bogie height of the transfer device used in the assembly process of various parts is controlled so as to be automatically adjusted according to the size and height of each assembly part and the physical condition of the worker, It is necessary to improve the stability of the process by protecting electric wires and motors from the outside and to provide a lane control apparatus for a lighter automobile component assembly line.
