Laser positioning (2D Laser) has been developed as a optical guide system. Laser positioning gives you many new production possibilities, replacing templates and other time consuming positioning methods.

 

The laser is a normal dot laser that is focused on the material surface, and is adjustable to allow for different mounting heights. Galvo motors control mirror angles in relation to the laser at high speed, the motors have a repeatability of 8 microradians, that's 8mm at 1'000'000mm. Therefore displaying the laser projection extremely accurately.

 

It is possible to compensate for material height differences in the LPM software, therefore making it possible to project 3D laser images.

 

The heart of a laser projector are the two galvo motors (see diagram below). A mirror is mounted on each motor which adjust the angle at which the laser dot is projected at high speed, moving the laser dot at such speed that it appears to project a continuous image. An image that is too large can be projected in divided layers to give a clearer view of the parts contained in the projection.

 

It is possible to install up to 16 laser projectors together, to work as a single large projector, to cover a larger working area. QteC recommend that a single laser not be used to cover an area of greater than 5 x 5 meters. With a 16 laser system it would be possible to project over an area of 20 x 20 meters, or 5 x 80 meters. Any number of lasers, up to a maximum of 16, can be connected to single controller PC, each projector working together to display a large image or seperate smaller images to optimise production possibilities.

LP-HDF is supplied as standard with LPM software ( Laser Projector Manager) that can control up to 16 lasers from the same PC. It is possible to shift from a 16 laser system to a 3 laser system if required from a single PC.

With LPM, it is possible to move the projectionaround within the working area, change the working height, change images, etc. just by using the mouse controls. It is also possible to connect a remote control to the system, making the most used controls easily operated from anywhere on the production floor.

 

If you wish to use the laser projector in conjunctiom with a processing machine, it will in most cases be possible to connect the laser to the machine and control the laser from the machines own controller.

 

Examples

Below are 3 examples showing the advantages in production a laser porojector can give.

The laser projector is also useful in the 'pick and place' application, where a part number barcode can scanned, the laser will then show the location of the scanned part in the storage area and where it is to be placed on the piece under production.

Contact QteC if you have any questions about laser projectors.

Product: Foam Elements.

Consists of 2 thin metal layers bonded to the foam.

 

The customer had previously used templates placed on top of the elements, using a marker pen to indicate where metal mounting plates are to be placed. 

With a laser projector, the elements can be produced without the use of templates, therefore reducing production time.

 

Product: Stair cases

 

 

 

The customer required a laser projector to be mounted on a CNC router machine used for the production of staircases. The laser projects the areas of material that are to be removed by the machine, thereby allowing fast and easy placement of the suction cups, saving time and damage to suction cups and tools.

 

 

Product: Wooden roof truss

 

 

 

With the use of laser projectors, the customer achieved a higher and more uniform build qaulity.

With production time greatly reduced as well as eliminating the need for templates with thousands of drawings available directly from a pc.
