Desktop robot enables focused plasma treatment

The JOT400 Plasma Cell with a programmable path control system performs cold plasma pre-treatment for products as small as a wristwatch computer up to a 10in tablet. "With our fully automated solution, pure surfaces for a stable adhesive bonding are achieved quickly while leaving easily harmed touchscreens untouched," explained Ville Vatanen, director at JOT Automation. "The plasma treatment is done precisely only to areas where it is needed to gain a high-quality tape or glue joint. This generates less scrap in the display gluing process leading to remarkable cost savings." "JOT's more advanced solution has a plasma brush application integrated to it for cleaning and removing tension from surfaces to achieve even higher-quality joints. The need for clean, strong joints in today's advanced displays is very important for the products' longevity and quality." The JOT400 plasma cell is claimed to be the most compact lean solution on the market, requiring less space and making it easy to move on a factory floor. It measures just 400 mm x 740 mm x 645 mm and has X-Y-Z servo axes. With a plasma path control, atmosphere plasma brush process, flame sensor and touchscreen user interface it is the most advanced of its kind.
