Vehicle Assembly Support
Laser Projection as Assembly Support for Vehicle Construction
In special-purpose vehicle construction (heavy duty vehicles, locomotives, freight cars), the use of laser projectors enables a fast and precise display of the target position of attachments and components on the frame or floor of the vehicle. This provides assembly workers with intuitive instructions and positioning assistance both at once, completely eliminating the need for high production costs and the time-consuming handling of stencils.
The production of special vehicles are often one-offs, which means the work process can at times be poorly automated. Even today, manual assembly still plays an important role in this industry. The steel frame inside a vehicle is a great example, as needs include brackets for hydraulics, welded parts on the vehicle floor, and wall elements.
The marking of mounting positions is currently carried out with the use of heavy metal stencils, which are placed on the workpiece.
Disadvantages of Stencil Use:
- Complex production processes
- Can only be moved with a crane
- Incidence of accidents while maneuvering
- The need for storage capacity
Laser projectors are the modern alternative to stencils. They project the precise positioning of components directly onto your workpiece. External contours and explanatory text such as part numbers can also be shown. When preparing the drawing data, care is taken that parts are grouped according to the work steps and internally assigned to different pencil colours. With the aid of a remote control, the operator can display the individual assembly groups one after the other and draw them out or install them directly.
- Greater flexibility
- Reduction of set-up time
- Fast and accurate positioning
- No template change required
A 90% time reduction is achieved, compared to manual set-ups.
