Intelligent 24 V linear modules with auto-learn technology dramatically simplify assembly automation
When SCHUNK unveiled the first prototypes of the SCHUNK ELP line of linear modules late last year, it caused a buzz in the automation world. SCHUNK, the competence leader for clamping technology and gripping systems, had developed the first low-maintenance compact linear modules with a 24 V linear motor drive. The new modules can adjust their movement profile fully automatically to individual component weights and can be easily operated by anyone. The series, which will be launched at Automatica 2016, is therefore ideal for creating more flexible assembly processes in Industry 4.0 environments.
Due to SCHUNK ELP linear modules, complete assembly systems can be built using 24 V technology. If the component weight changes, the SCHUNK ELP linear axis changes its movement profile fully automatically within just two to five strokes.
No mechatronic know-how or extra space in a control cabinet is required to use the intelligent linear module. The drive, control unit, and specially developed auto-learn technology are completely integrated into the module. The module is easy to set up: The axis is connected via a standard plug (M8/M12) and the end position is mechanically set using an Allen key and the speed of extension and retraction is adjusted using two rotary encoding switches directly on the module. Automatic programming is completed after two to five strokes. This is indicated by an LED. If the component weight changes during the process, the axis automatically adjusts its movement profile within just a few strokes. In contrast to pneumatic modules, no throttles have to be adjusted, and compared to electrically controlled modules, no new sequences have to be added. The axis fits seamlessly into the pillar of alternative mechatronic solutions from SCHUNK, which can be used as a 1:1 replacement for pneumatic components. For the first time, complete assembly systems with linear axes, rotary modules and grippers can be implemented entirely using 24 V technology.
Due to the auto-learn function of the compact SCHUNK ELP linear modules, no knowledge of mechatronics is required to commission them. The drive and controller are completely integrated into the axes.
long-lasting and virtual maintenance-free
Since the compact units do not require hydraulic shock absorbers, commissioning and maintenance work is virtually eliminated. What’s more, there is no need to worry about potential damage to your system or long downtimes due to defective shock absorbers. The electric axes also score points due to their long lifetime, lower operating costs, minimized noise emissions and outstanding process stability. The SCHUNK ELP series is compatible with all controllers since everything is controlled via digital I/O. Built-in C-slots enable stroke position monitoring via magnetic switches. The linear axes will be available starting July 2016 in three sizes (25, 50, 100) each with three stroke versions. They have a repeat accuracy of 0.01 mm and a maximum nominal stroke of 200 mm. Due to the standardized drilling pattern, they can be combined directly with numerous modules from the world’s largest system range for modular high-performance assembly from SCHUNK. Standardized power and sensor distributors as well as cable sets will be added to the product line in the near future.
