Solution Overview
Problem
State-of-the-art separation modules in robot cells are time-consuming to replace in case of faults, leading to reduced system availability and inefficiencies in handling joining elements like semi-hollow punch rivets.
Innovation Solution
A compact separating device mounted on a joining robot with a quick-change mechanism allows for rapid exchange of separation modules, utilizing a floating base plate and quick-change device to maintain position and enable easy replacement, along with a 90° bend buffer section for efficient hose routing and adaptable hose connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If singulation modules are used in a robot cell according to the state of the art, then joining elements can be processed, but changing them in the event of a malfunction is time-consuming and reduces system availability
Solution Approach 1:
The singulation system is divided into modular singulation modules that can be independently replaced. Each module contains specific functional components (storage container, orientation device, conveying device) that can be quickly swapped out without affecting the entire system, enabling rapid replacement during malfunctions.
Solution Approach 2:
The device is mounted on the assembly robot in a floating manner, allowing dynamic positioning and easy removal of modules. The base plate and mounting structure are designed to accommodate quick changes, transforming a static installation into a dynamically replaceable configuration.
2Ease of operation
If the device is mounted on the assembly robot in a floating manner, then quick module replacement is enabled, but precise positioning and stability must be maintained
Solution Approach 1:
The mounting system is segmented into a base plate attached to the robot and a separate device portion that can be quickly connected and disconnected. This segmentation allows easy replacement while maintaining stable operation during use through precise connection interfaces.
3Productivity
If feed hoses are used for transporting joining elements, then elements can be delivered to the joining tool, but the transport distance is limited to less than 20 meters and compressed air energy is consumed
Solution Approach 1:
The patent utilizes pneumatic systems through compressed air to propel joining elements through feed hoses to the joining tool. The compressed air is supplied at different points depending on the hose connection side, enabling flexible and efficient element transport.
4Adaptability or versatility
If adapters are provided for different hose connections, then flexibility in mounting is improved, but device complexity increases
Solution Approach 1:
The device incorporates universal adapters that can accommodate different hose connection types and configurations. These adapters provide multi-functionality, allowing the same device to work with various hose arrangements (left or right side connections, different angles) without requiring multiple specialized components.
