Bead Ring Bonding Cord Winding Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bead ring bonding cord winding apparatuses fail to securely hold the ends of the bonding cord between the wound portion and the bead ring, leading to potential separation or deformation of the winding ends.
Innovation Solution
A bead ring bonding cord winding apparatus featuring a ring moving member that feeds the bead ring in a circumferential direction, a gripping member that grips the bonding cord end, and a rotation member that spirally winds the cord around the bead ring, with the gripping member positioned upstream to ensure the cord end is held between the wound portion and the bead ring without additional structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the bonding cord is only spirally wound around the bead ring without additional holding structures, then the device structure remains simple, but the end of the bonding cord may become separated from the winding ends causing displacement or deformation
Solution Approach 1:
The wound portion of the bonding cord itself serves as the holding mechanism. The cord is wound multiple times around the bead ring, and the friction and mechanical interlocking of the wound cord against the bead ring automatically hold the end in place without requiring separate holding structures. The system uses its own output (the wound cord) to achieve the holding function.
2Reliability
If the gripping member is positioned downstream of the rotation member, then the cord end can be held during winding, but additional structures are required to maintain the cord end between the wound portion and the bead ring
Solution Approach 1:
Instead of positioning the gripping member downstream to hold the cord end, the invention inverts the approach by positioning the gripping member upstream. This allows the cord end to be fed through the rotation member and naturally trapped between the wound portion and the bead ring as the winding progresses, eliminating the need for downstream holding structures.
3Reliability
If a complex holding structure is added to secure the bonding cord end, then separation and deformation are prevented, but the device structure becomes complicated
Solution Approach 1:
The wound bonding cord creates its own holding mechanism through multiple windings around the bead ring. The friction and mechanical interlocking generated by the wound cord itself secure the end position, eliminating the need for separate holding structures or complex apparatus modifications.

AI summary
A bead ring bonding cord winding apparatus includes a feed roller that feeds a bead ring, which is formed by winding a wire a multiple number of times, in a circumferential direction of the bead ring, a gripping member that grips an initiating end of a bonding cord, and a rotation member that rotates past an inner side and an outer side of the bead ring while holding the bonding cord. In the bead ring bonding cord winding apparatus, while the bead ring is fed in the circumferential direction, the rotation member is rotated past the inner side and the outer side of the bead ring to spirally wind the bonding cord around the bead ring. The gripping member is located at an upstream side of the rotation member in the feeding direction of the bead ring.
