Abstract: PURPOSE: A safety joint device for a robot is provided to prevent a compression spring from being deformed by allowing the end of a spring guide to be rotatable. CONSTITUTION: A safety joint device(100) for a robot comprises a fixing unit(110) and a rotating unit(120). The rotating unit is rotatably coupled to the fixing unit. A cam unit(124) is protruded from the center of the rotating unit. The fixing unit comprises followers(117) and an elastic units(114). The elastic units restrict the rotation motion of the rotating unit by applying elastic force to the followers. When a value more than critical torque is inputted to the rotating unit, the cam unit is separated from the followers.

Abstract translation: 目的：提供一种用于机器人的安全关节装置，以通过允许弹簧导向件的端部可旋转来防止压缩弹簧变形。 构成：用于机器人的安全关节装置（100）包括固定单元（110）和旋转单元（120）。 旋转单元可旋转地联接到定影单元。 凸轮单元（124）从旋转单元的中心突出。 固定单元包括从动件（117）和弹性单元（114）。 弹性单元通过向追随者施加弹力来限制旋转单元的旋转运动。 当超过临界扭矩的值被输入到旋转单元时，凸轮单元与从动件分离。
