Side Home-Position Device for Flexible Vehicle Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body assembly systems are inflexible and require extensive preparation and high initial investment to accommodate various vehicle types, as they are designed for specific vehicle models and cannot efficiently handle more than five kinds of vehicles due to fixed side gates.
Innovation Solution
A side home-position device that includes a post frame, a moving member, a main control unit, a clamper, and an operating portion, allowing a common use side jig to be returned to a working position, supporting and accurately positioning side panels for various vehicle types through a combination of movable components and control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If side gates are fixedly disposed at four sides of a main rotation buck, then the structure is simple and stable, but it is impossible to assemble more than five kinds of vehicle bodies
Solution Approach 1:
The side gate is transformed from a fixed structure to a movable one, capable of rotating between a home position and a working position. This dynamic configuration allows the same gate to serve multiple vehicle types by adjusting its position, thereby improving adaptability without proportionally increasing system complexity
Solution Approach 2:
A single side gate structure is designed to perform multiple functions by serving different vehicle types through positional adjustment. The gate can accommodate various vehicle body configurations (sedan, SUV, truck, etc.) by rotating to appropriate positions, eliminating the need for multiple dedicated gates for each vehicle type
2Productivity
If conventional fixed side gate systems are used, then facility preparation time is long and initial spending increases, but the system can handle specific vehicle models
Solution Approach 1:
The movable side gate system allows a single facility to handle multiple vehicle types (sedan, SUV, truck, and more) without requiring separate dedicated lines for each vehicle type, thereby reducing facility preparation time and initial investment while maintaining productivity
3Adaptability or versatility
If a common use side jig is used for various vehicles, then versatility improves, but the jig cannot be accurately positioned for different vehicle types
Solution Approach 1:
The side gate's ability to rotate to different positions enables a common side jig to be accurately positioned for various vehicle types. Each vehicle type corresponds to a specific gate position, ensuring that the jig maintains precise alignment and positioning accuracy despite handling diverse vehicle configurations

AI summary
A side home-position device for a vehicle body assembly system for various vehicle types is disclosed, which can be used to return a common use side jig that controls a side panel to a working position of a main buck process. The device includes a post frame that is disposed in a vertical direction corresponding to the working position, a moving member that is movably disposed at the post frame in a width direction of a vehicle body and substantially supports the common use side jig, a main control unit in connection with the moving member and which returns the common use side jig to an original position, a clamper disposed on the moving member which clamps a matching portion of the common use side jig for the moving member, and an operating portion disposed at the post frame and which moves the moving member in a width direction of the vehicle body.
