Evosys develops solution for more-efficient laser plastic welding

Nov. 13, 2020
The purpose in developing the human-machine interface for its laser systems was the intuitive visualization and simplification of the laser welding process operation.

Evosys Laser (Erlangen, Germany) develops and manufactures tailor-made systems for laser welding of plastics. The purpose in developing the Next Generation HMI (human-machine interface) for its laser systems was the intuitive visualization and simplification of the laser welding process operation, including its mechanical movements. The new solution is functionally independent of the control system used, offering the possibility to be adapted to growing requirements by smart additional modules.

A central overview provides the operator with information tailored to his area of activityprocess, production, and statistics. All other subpages are grouped together in function groups, with the header on each page having the same structure. This shows basic information about the machine, such as operating mode, information, warning or fault messages, as well as the current time and the current unique window number. Basic navigation is carried out via the sidebar on the right-hand side, which contains the corresponding operating elements. 

The company's Next Generation HMI also handles the visualization and evaluation of the process data, eliminating the need for additional hardware by displaying all process-relevant information about the currently processed assembly. In addition, the last data records can be compared in the history of the HMI. A statistics page uses various counters to record order and production quantities and determines quality parameters. These are then displayed graphically. 

The HMI is also used to store recipe data sets, export and import envelopes, create them, and other system functions. For example, the monitoring of the hard disk capacity or the display of a USB camera can be integrated. The system can thus be operated with different machine controllers, which are not visible to the end user. This does not change the functionality and above all the operation of the machine.
