Automotive Clip Installation Tool with Vacuum Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual insertion processes for attaching automotive clips are time-consuming, lack ergonomics, and are prone to quality errors such as missing or unseated clips, with no known automated solutions for efficient and precise installation.
Innovation Solution
A clip installation tool system featuring a magazine for aligning clips and end-of-arm tooling with cylindrical pegs that use vacuum and air blowoff to pick up, hold, and place clips with precision, allowing for simultaneous handling of multiple clips and self-verification of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion processes are used for attaching clips, then flexibility in handling different clip designs is maintained, but the process becomes time-consuming and prone to quality errors
Solution Approach 1:
The system uses vision guidance to automatically detect clip positions and guide insertion, with sensors verifying proper installation. The process is self-correcting and requires minimal human intervention, achieving both high speed and high reliability through automated self-verification
Solution Approach 2:
Manual mechanical insertion is replaced with an automated system combining vision guidance, robotic positioning, and sensor verification. This substitution eliminates human error while maintaining the ability to handle various clip designs through programmable control
2Productivity
If automated clip installation is implemented, then productivity and consistency are improved, but the system complexity increases
Solution Approach 1:
The system uses universal components such as suction cups for picking up different clip types, a magazine that can hold multiple clip varieties, and vision guidance that can recognize various clip designs. This multi-functionality reduces the need for specialized equipment for each clip type
Solution Approach 2:
A magazine serves as an intermediary between clip storage and the installation head, organizing clips for efficient access. The vision system acts as an intermediary between the robot and the clips, providing guidance without requiring complex direct control mechanisms
3Ease of operation
If mechanical lock mechanisms are used to pick up clips, then clip handling is achieved, but the mechanisms become complicated and require constant adjustment
Solution Approach 1:
Complex mechanical lock mechanisms are replaced with simple suction-based pickup using vacuum cups. This substitution eliminates the need for complicated locking and releasing mechanisms while providing reliable clip pickup through atmospheric pressure
Solution Approach 2:
The system uses pneumatic vacuum cups to pick up and hold clips during transport and installation. The pneumatic system provides simple on/off control through vacuum generation and release, eliminating complex mechanical adjustment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables fast, ergonomic, and precise automated installation of clips, reducing the likelihood of errors and ensuring all clips are properly seated, with the ability to handle variations in clip design and size.
Implementation Method 1
vacuum generation to the peg(s) assists with holding the clip(s)
Implementation Method 2
air blowoff to the specific peg(s) is applied to insure foam or other clip structures stay in place on the clip and to insure the clip is removed from the peg(s)

AI summary
Clip installation tooling and method for installing clips including a magazine for holding a plurality of clips and clip end of arm tooling for picking up at least one clip at a time. The magazine stops at predetermined intervals for spacing each respective clip into openings on the magazine. The clip end of arm tooling has at least one body connected to a plurality of cylinders each with an inlet/outlet port receiving vacuum/air blow off. The clip end of arm tooling picks up one or more clips from the magazine at a time. The vacuum generation to the port(s) assists in holding the clip(s) and eliminates dropping clip(s) prior to placement for installation of the clip(s). After the clip(s) is/are placed, air blow off through the port(s) insures clip(s) are removed from the clip end of arm tooling and stay in the desired position(s).
