[Case Study] Solving Insufficient Holding Force in the Opening and Closing Mechanism of a Label Printer with Precision Control Mechanism

Proposing a 0.3Nm model of the one-way hinge! Free stop is possible until the specified torque is applied.

We would like to introduce a case where the insufficient holding force of the opening and closing part of a label printer was resolved through a precision control mechanism for unidirectional torque generation and unidirectional free rotation. The issue arose due to an increase in weight at the opening and closing points caused by design changes, which resulted in insufficient force with the existing hinges. We calculated the necessary torque and proposed a 0.3Nm model of a one-way hinge. This allowed for free stopping until the specified torque was applied. 【Case Overview】 ■ Issue - The existing hinges were insufficient due to an increase in weight at the opening and closing points caused by design changes. ■ Solution - We calculated the necessary torque and proposed a 0.3Nm model of a one-way hinge. ■ Effect - Guaranteed lifespan of 20,000 opening and closing cycles (round trips) based on catalog specifications. *For more details, please download the PDF or feel free to contact us.
