Umbilical Guide Member Prevents Interference in Robot Wrist

The patent introduces a guide member as an intermediary component between the umbilical member and the end effector. This guide member includes a guiding section that constrains the umbilical member's movement path, and a limiting section that prevents the umbilical member from extending beyond a predetermined distance from the wrist section. The intermediary guide member resolves the contradiction by allowing the umbilical member to have sufficient length for operation while preventing it from becoming slack and interfering with external equipment.

The patent segments the fixing mechanism into two distinct parts: a fixing section that securely attaches the umbilical member to the guide member during operation, and a releasing section that enables easy detachment for maintenance. The fixing section includes fixing protrusions and grooves that provide stable connection, while the releasing section allows the umbilical member to be quickly removed and replaced. This segmentation resolves the contradiction by providing both secure fixation during use and ease of replacement during maintenance.

The patent merges multiple functions into the guide member structure. The guide member integrates the guiding section for umbilical member constraint, the limiting section for extension control, and the fixing/releasing sections for secure attachment. By combining these functions into a single integrated component rather than separate parts, the patent achieves high rigidity for vibration prevention while avoiding excessive structural complexity. The merging principle resolves the contradiction by providing stability through functional integration rather than through adding multiple separate rigid components.
