Wire Harness Taping Head With Rotating Cut-and-Clamp Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing taping heads for wire harnesses lack a compact and lightweight design that efficiently cuts and repositions adhesive tape, leading to inefficiencies in automated taping processes.
Innovation Solution
A taping head with a rotatable tape dispenser and a clamping unit that includes a cutting blade and anvil, allowing for simultaneous cutting and clamping of the tape, along with a spring-loaded receptacle and guide roll for proper tape orientation, enabling compact and automatic taping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the clamping unit is mounted to both the base plate and the rotatable tape dispenser, then the taping head becomes compact and lightweight, but the mechanism complexity increases
Solution Approach 1:
The clamping unit is merged with both the base plate and the rotatable tape dispenser through the anvil, creating a unified structure that reduces the need for separate mounting mechanisms and minimizes overall weight while maintaining functional integrity
2Strength
If the anvil is rigidly connected to the rotatable tape dispenser, then the tape is firmly held during cutting, but the clamping element cannot rotate with the dispenser
Solution Approach 1:
The system is segmented into two independent rotational systems: the anvil rigidly connected to the rotatable tape dispenser for firm tape holding, and the clamping element independently mounted on the base plate, allowing each component to perform its specific function without interference
3Manufacturing precision
If the cutting blade enters the slot in the anvil, then cutting precision is improved, but the mechanism complexity increases
Solution Approach 1:
The slot in the anvil serves multiple functions: it guides the cutting blade for precise cutting, provides a reference surface for positioning, and allows the blade to enter and exit smoothly, eliminating the need for separate guiding mechanisms

AI summary
A taping head for taping a wire harness includes a base plate with a first aperture for receiving a wire harness. A tape dispenser with a second aperture is configured to rotate a roll of tape around the center of the first and second apertures. The taping head further includes a clamping unit configured to clamp a free end of the tape.
