JENvelt™ Vision-enhanced laser tool - Smart optical system platform for laser material processing

The core of the system is the "All-in-One" software, which combines scanner and laser control as well as image recognition with artificial intelligence. It depicts If a production order has been set up and optical markers are defined for the exact positioning of the laser spot, ´prooves´ and ´compares´ the device determines the position of the workpiece relative to the laser spot during the running process and repositions it if necessary. This is done with a positioning and repeat accuracy of up to 10 µm. The position of the laser spot is always exactly at the predefined position, independent of the shape and position tolerances of the component.

Complex clamping fixtures become obsolete or can fail more easily if they are necessary due to the process. The process is particularly advantageous when machining workpieces that are manufactured with comparatively high tolerances, such as plastic parts in the injection molding process. An increased good yield from the first component improves the production result and productivity.

Calibration at the touch of a button ensures flexible and fast machine changeover, for example in the case of changing production orders. Consistently high accuracy and reproducible results make production more efficient.

• All-in-one software solution
• Combines classic laser setup software with image channel
• Image recognition features - Object recognition
• Coax image channel - thus very high resolution ("stitching" of the image)
• Positioning of the laser relative to the recognized features
• High precision
• Software works independently from laser and scanner used

The Jenoptik JENvelt vision-enhanced laser tool is the perfect synergy of high quality hardware, smart software and service offerings which enables our customers to focus on their key competencies.

The integrated vision channel is perfectly aligned and calibrated to the galvoscanner. In combination with our software solution we ensure the positioning of the laser spot independent from positional and shape tolerances of the part to be processed.

Our software solution is combining laser related programming tasks (settings like laser power, pulse rep. reates, modulation of laser energy, etc.), galvoscanner related programming tasks (settings like speed, jumps, number of cycles, etc.) and vision related programming tasks (settings like illumination, gain, pattern recognition, etc.) in one software, easy and fast process setup, intuitive handling, fast setup cycles.

The capability of surely recognizing the part position or contour position enables our customers to re-think the overall machine concept – processing different variants, for some processes even no fixture is needed, less laser power is needed as you always hit your target or even weakened part tolerances are possible as the system always follows the real path or recognizes the real position. This feature leads to reduced fixture costs and reduced part costs.

Setting up laser processes is time consuming and not easy. Our vision channel helps to reduce the setting-up times significantly. In particular this is important for customers that work on different and frequently changing tasks. Our software is helping to find the right parameters in an intelligent way.
