Automated Wire Taping System with Detachable Cassette
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automated wire taping systems require manual intervention and significant downtime when changing tape rolls, as the entire assembly line must be halted for operators to replace the tape roll, leading to inefficiencies, especially when multiple color changes are needed during wiring harness assembly.
Innovation Solution
An automated wire taping system with a detachable tape roll cassette system that allows for automatic disconnection and reconnection of tape rolls, enabling the taping robot to switch between different cassettes without manual intervention, using a releasable connector mechanism and a storage device to manage multiple cassettes and facilitate seamless tape roll changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tape roll replacement is used, then the taping robot can be simple in structure, but the assembly line experiences excessive downtime and reduced productivity
Solution Approach 1:
The tape roll system is segmented into a detachable cassette unit that can be independently replaced. The cassette includes a tape roll mounted on a spindle, with the entire assembly removable from the taping head via releasable connectors. This segmentation allows rapid replacement without complex manual disassembly procedures, reducing downtime while maintaining system simplicity.
Solution Approach 2:
Multiple tape rolls are pre-loaded into separate cassettes and stored in a storage device adjacent to the taping head. When the current tape roll is depleted, the system can quickly switch to a pre-prepared cassette without requiring manual tape unwinding or complex reconfiguration. The releasable connectors are pre-positioned to enable rapid detachment and attachment of cassettes.
2Loss of time
If automatic cassette replacement is implemented, then downtime is reduced, but the system complexity increases with releasable connectors and storage devices
Solution Approach 1:
The connector system transitions from a fixed, permanent attachment to a dynamic, releasable connection. The releasable connectors allow the cassette to be easily detached and reattached, enabling automatic replacement cycles. This dynamic connection mechanism reduces replacement time while keeping the added complexity manageable through standardized connector designs.
Solution Approach 2:
The cassette acts as an intermediary component between the tape roll and the taping head. Instead of directly attaching the tape roll to the head, the cassette serves as a removable intermediary that simplifies the replacement process. The storage device also acts as an intermediary, holding multiple cassettes ready for quick exchange, thereby reducing the complexity of direct automated replacement mechanisms.
3Productivity
If permanent tape roll mounting is used, then the connector system is simple, but the entire assembly line must be halted for tape roll changes
Solution Approach 1:
The tape roll mounting system is segmented into a detachable cassette unit with releasable connectors, allowing the cassette to be quickly removed and replaced without halting the entire assembly line. This segmentation transforms a previously permanent mounting into a modular, rapidly exchangeable unit, significantly improving operational efficiency.
Solution Approach 2:
The system enables self-service tape roll replacement through the automated cassette exchange mechanism. The releasable connectors allow the cassette to be easily detached and reattached without requiring complex manual intervention or specialized tools, making the replacement process simple and efficient while maintaining continuous production.

AI summary
An automated wire taping system comprises a taping robot having a taping head mounted on an arm of the robot that in use wraps tape around a cable or collection of cable. A tape roll cassette includes a roll of tape rotatably mounted to a cassette body and includes at least one releasable connector for connecting the cassette to the taping head. A storage device includes a holder for receiving the cassette and a release device arranged to automatically operate the at least one releasable connector to disconnect the cassette from the taping head when the cassette is received within the holder.
