System for manufacturing side panel of vehicle

Abstract

A system for manufacturing a side panel of a vehicle, the system including upper running rails and lower running rails to provide a movement path of a cart, the cart having a support frame, a transfer roller, and a friction bar provided at a bottom surface of the support frame, wherein the side panel may be mounted on the cart and the cart moves selectively along the upper running rails and the lower running rails, at least a friction drive unit and at least a friction wheel disposed along the upper and lower running rails wherein the at least a friction drive selectively rotates the at least a friction wheel to move the cart by selectively engaging at least one of the friction wheels with the friction bar of the cart, and an external unit supporting an edge portion of the side panel during key welding process.

Description

technical field [0001] The present disclosure relates to a system for manufacturing a side panel of a vehicle. In particular, it relates to a system for manufacturing a side panel of a vehicle, wherein the side panel is secured during critical welding using an external unit to cope with various types of carts for various vehicle models ( cart), the cart is driven by frictional contact to reduce manufacturing costs and reduce installation space. Background technique [0002] The vehicle body panels used to construct the vehicle body are formed by stamping and conveyed to a vehicle body assembly line for assembly into the vehicle body. Exterior panels, such as doors, trunk lids, hoods, fenders, etc., are then installed on the assembled vehicle body before undergoing a painting process. [0003] Next, various components, such as the engine, transmission, interior / exterior parts, etc., are assembled in an assembly line (trim line) to produce a complete vehicle. [0004] figu...

AI Technical Summary

Problems solved by technology

[0014] However, the conventional linear motor 1 is arranged along the running track to move the cart 2, so the number of linear motors 2 is very large, which leads to an increase in cost

In addition, the capacity of the inverter for controlling the linear motor 1 increases, which leads to an increase in manufacturing cost

Moreover, the size of its control panel is also increased, thereby increasing the installation space, which is not conducive to the layout

[0015] In addition, since the linear motor 1 drives the cart 2 in a non-contact manner, errors frequently occur when the moving speed of the cart 2 is controlled, and manufacturing and assembly costs increase to maintain the gap between the linear motor 1 and the cart 2

[0016] In addition, every time a new vehicle model is developed, some processes will be added to the production line, which is limited by system management

In addition, the turntable is expensive to manufacture
