Bayonet Coupling Plug-in Adapter for Robot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for adjusting industrial robots are laborious and time-consuming, requiring frequent screwing and unscrewing of adjustment instruments, which includes disconnecting and reconnecting electrical connecting lines, and often necessitate multiple styluses per joint, leading to potential accuracy losses.
Innovation Solution
A plug-in adapter with a thread for screwing onto an adjustment instrument and a plug-in device for quick connection to robot access openings, eliminating the need for multiple styluses and reducing the complexity of attaching and detaching the adjustment instrument, using a bayonet coupling mechanism for secure and accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adjustment instruments are frequently screwed and unscrewed for robot adjustment, then the adjustment can be performed, but the adjustment process becomes laborious and time-consuming
Solution Approach 1:
The adjustment system is divided into separate modular components: the adjustment instrument, the plug-in adapter with bayonet coupling, and the robot interface. This segmentation allows the plug-in adapter to remain permanently connected to the robot while the adjustment instrument can be quickly attached and detached, eliminating the need to repeatedly screw and unscrew the entire assembly.
Solution Approach 2:
The bayonet coupling mechanism provides a dynamic connection system that transitions from a permanent threaded connection to a quick-connect/disconnect interface. This dynamic coupling allows for rapid attachment and detachment of the adjustment instrument while maintaining a stable connection during measurement, resolving the contradiction between secure connection and quick adjustment.
2Measurement precision
If multiple styluses are used per joint for adjustment, then comprehensive measurement is achieved, but device complexity and potential accuracy losses increase
Solution Approach 1:
The plug-in adapter with bayonet coupling serves as a universal interface that can accommodate the adjustment instrument for measuring multiple joints. This single multi-functional adapter replaces the need for multiple specialized styluses, reducing device complexity while maintaining comprehensive measurement capability across all robot joints.
Solution Approach 2:
The plug-in adapter acts as an intermediary component between the robot and the adjustment instrument. It provides a stable reference interface that eliminates the need for multiple direct contact styluses, reducing complexity while ensuring accurate measurement transmission from the robot joints to the measurement system.
3Reliability
If traditional screwing connections are used for attaching adjustment instruments, then secure connection is achieved, but the connection process becomes complex and time-consuming
Solution Approach 1:
The traditional mechanical screwing connection system is replaced with a bayonet coupling mechanism. This substitution maintains the reliability and security of the connection through positive engagement and locking features, while dramatically improving ease of operation by eliminating the need for threading and unscrewing operations.
Solution Approach 2:
The connection mechanism transitions from a multi-turn threaded parameter (screwing) to a single-motion bayonet coupling parameter (click-lock engagement). This parameter change maintains connection security through mechanical locking while reducing the operational steps and time required for attachment and detachment.

AI summary
A plug-in adapter includes a thread designed to screw the plug-in adapter to an adjustment instrument, a plug-in device designed for detachably connecting the plug-in adapter to a counter plug-in device of an access opening on a robot for a reference position marking of the robot, and a stylus designed to couple a measuring tip of the adjustment instrument to the reference position marking. The plug-in device has a plug-in section that is designed for axially plugging of the plug-in section into the counter plug-in device of the robot.
