Description

Method of manufacturing automobile

The present invention relates to a method for manufacturing a vehicle, and more particularly, to an improved method for manufacturing a vehicle for supplying related parts assembled to a vehicle body or a door.

The automobile manufacturing process is largely composed of a press process, a car body process, a painting process, and an assembly process based on a passenger car. The assembly process is to install interior and exterior design parts such as interior, instrument panel, seat, and window glass on the painted body, assemble units such as engine, transmission, and axle, complete the automobile by performing electrical parts, wiring, and piping work, and check the quality. This is the final process to finish the product.

The assembly process works on a conveyor, where there is a main line and an attached sub line. Detailed processes are shipped to finished cars through PBS (Painted Body Storage), through the process of assembling related parts such as interior and exterior (trim) process, chassis, etc., final assembly process and test process.

In a conventional assembly process, related parts are supplied to an assembly line in the following manner and assembled to a vehicle body or a door. Related parts to be assembled on the body or door are loaded along the assembly line. The operator collects the relevant parts of the relevant parts that are loaded and assembles them to the body or door.

By the way, the above-described method also serves to collect the relevant parts by the worker assembling the related parts, work efficiency is low, fatigue can be great. In addition, the position where the related parts are stacked close to the assembly line so that an operator can easily access the related parts, the space between the loaded position and the assembly line is narrowed. Accordingly, the worker may feel inconvenient to work.

An object of the present invention is to solve the above problems, to improve the method of supplying the relevant parts to the assembly line to improve the work efficiency of the operator, to provide a vehicle manufacturing method that can reduce fatigue and discomfort.

According to an aspect of the present invention, there is provided a method of manufacturing a vehicle, the method including: (a) storing, in boxes, relevant parts loaded in boxes at a loading position where relevant parts to be assembled on a vehicle body or a door are loaded; (b) supplying at least one box next to the vehicle body or the door in association with the movement of the vehicle body or the door while circulating the boxes containing the related parts between the loading position and the assembly line where the vehicle bodies or doors are moving; And (c) assembling the relevant parts to the bodies or doors to return empty empty boxes to a stowed position.

According to the present invention, the operation of storing the related parts in the boxes and the assembling of the related parts in the vehicle body or the door may be performed by different operators. Accordingly, since the storing operation and the assembly operation can be divided into labor, not only can the work efficiency be increased, but also the fatigue of the operator can be reduced.

In addition, since the related parts are continuously supplied to the assembly line while the boxes containing the related parts are circulated between the loading position where the related parts are loaded and the assembly line, the related parts can be quickly supplied to the assembly line.

In addition, since the worker who performs the assembly work does not need to separately collect related parts to be assembled, the space between the loading position where the related parts are loaded and the assembly line can be widened. Accordingly, there is an effect that the worker can work more comfortably.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a process of supplying the relevant parts to the assembly line in which the vehicle body is moving in the vehicle manufacturing method according to an embodiment of the present invention.

The related parts 111 may be quickly supplied to the 130. In addition, since the worker who performs the assembly work does not need to separately collect the related parts 111 to be assembled, the loading position 110 in which the related parts 111 are loaded may be placed as far as possible from the assembly line 130. Accordingly, since the space between the loading position 110 and the assembly line 130 can be widened, the worker can work comfortably.

Meanwhile, the process of supplying the related parts 111 to the assembly line 130 while circulating the boxes 120 stored therein may be performed by auto guided vehicles (AGVs) 140. The unmanned trucks 140 carry the boxes 120 containing the related parts 111 one by one. In addition, the unmanned vehicle 140 moves in an infinite track while maintaining the same interval as the interval between the vehicle body (B). In this process, the driverless carriages 140 are located one by one next to the vehicle body B. Accordingly, the unmanned transportation vehicles 140 circulate between the loading position 110 and the assembly line 130, one by one, with the boxes 120 containing the related parts 111 stored thereon, next to the vehicle body B. Can be supplied one by one.

Between the unmanned transport vehicle 140 and the loading position 110, the plurality of boxes 120 containing the related parts 111 are circulated one by one to the unmanned transport vehicles 140, and the unmanned transport vehicle 140 Receiving the empty box 120 loaded in the) may be added to the process of recovering to the loading position (110).
