Technologies

Zenna's powerful combination of technologies once again highlights its innovative DNA. The integration of three distinct technologies into one unified laser system makes the ZocuPRO software platform a success. Zenna seamlessly combines lasers, robots, and the integration of camera systems into a user-friendly and easy-to-use software package.

Lasers & ScannersRobotsVision

The laser is the main component of the machine. Depending on the type of machine and desired results, one or more lasers are installed. Inside the laser, the laser beam is generated and directed to the scanner through tubes and mirrors.

The scanner contains two mirrors that move rapidly, guiding the laser beam to the material for cutting. The cutting process is contactless. The control of the lasers and scanners is managed within the ZocuPro platform. Various settings can be modified through the HMI (Human-Machine Interface) like speed and laserpower. 

The addition of robots involves further automating the production line. These robots will stack the products on a separate conveyor belt (abrasives) after cutting or guide them after the tables (airbags), where they can be manually picked up. The robots determine the position of the products based on the drawing loaded into the system.

When the line is equipped with Vision as well, the robots receive offsets from the Vision systems, allowing the robot to obtain the exact (revised) location of the product. This rapid exchange of data and its processing are handled within the ZocuPRO software package.

Camera systems can be integrated into the machines. These camera systems, known as "Vision," capture an image of the material before it is cut and compare its position with the loaded drawing in the HMI. Any necessary corrections are sent to the scanner, which then implements them to ensure consistency in each cut product.

After cutting, a new photo can be taken, transmitting the results to the robot. Any corrections for shifted products are thus addressed, ensuring that the robot always has accurate data and picks up the products in the correct location. The integration of this Vision system and the transfer of data converge within the ZocuPro software

Laser Beam Manipulation

The manipulation of the laser beam can be achieved through two methods: using a scanner with rotational positioning or through axial positioning.Zenna employs both positioning techniques, depending on the application and customer requirements. Whether you are aiming for sublime precision with axial positioning or higher production speed with rotational positioning, our expertise is at your disposal. However, over the past decade, Zenna has specialized in complex scanning applications and has become a leading integrator of scanners, often in conjunction with robot product handling and visual material qualification.

Axial Positioning with Nozzle

Our advanced industrial laser cutting machines offer two approaches to laser beam manipulation: axial positioning with a nozzle. This process is characterized by precise control over the laser beam using an XY system.

Technical Aspects:

• XY System: The nozzle is moved with extreme precision in the XY directions, enabling the realization of tight and highly detailed cutting paths.
• Straight-Cut Quality: Axial positioning results in tight and straight cutting lines, making it ideal for producing components with sharp angles and clear contours.
• Close to the Cutting Point: The nozzle is positioned directly above the cutting point, resulting in minimal distance between the laser beam and the material surface.
• Optimal Accuracy: Axial positioning is ideal for applications where absolute accuracy and minimal tolerances are crucial.

Rotational Positioning with Scanner

An alternative approach that we offer utilizes rotational positioning with a scanner. This method employs advanced mirror technology for efficient movement of the laser beam across the work surface.

Technical Features:

• High Speeds: The rapid movements of the scanner result in significantly shorter cutting times, enhancing overall productivity.
• Versatility: Due to the swift movements of the mirrors, scanners are highly versatile, providing extensive adaptability for cutting and on-the-fly switching between complex shapes and patterns.
• Scanner System: The mirrors within the scanner system are rapidly rotated to move the laser beam across the material surface.
• Suitable for Complexity: The scanner is particularly well-suited for applications involving complex shapes where speed is crucial.

Combined Use for Optimal Flexibility

By combining both methods, the best of both worlds can be leveraged. For instance, utilizing a scanner for rapid contours and a nozzle for detailed finishing. This results in a laser machine where two integrated laser stages are employed. The first stage incorporates a laser with a scanner, while the second stage features a laser with a nozzle.
