Setting Head Adhesive Deposition for Bonding Functional Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in attaching functional elements, such as metal or fiber-reinforced plastic components, to plastic components without damaging or losing the adhesive, particularly during handling and transport, as existing methods face risks of adhesive damage or loss due to improper application and handling.
Innovation Solution
A device with an injection system applies adhesive in the form of rings or drops directly to the contact surface within a setting head, minimizing the risk of adhesive damage and ensuring precise application, which can be integrated with various devices like presses or robots for efficient attachment of functional elements to plastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive is pre-applied to functional elements before handling and transport, then attachment readiness is improved, but adhesive damage or loss occurs during handling and transport
Solution Approach 1:
The adhesive is applied to the functional element just before attachment in the setting head, rather than being pre-applied during earlier handling stages. This preliminary action is timed optimally to ensure the adhesive is in place when needed but has not been exposed to damaging handling and transport conditions
Solution Approach 2:
The adhesive application step is extracted from the earlier handling and transport phases and separated into a distinct operation that occurs only in the setting head immediately before attachment. This separation prevents the adhesive from being present during conditions that cause damage or loss
2Ease of operation
If adhesive is applied outside the setting head, then application flexibility is improved, but contamination risk increases
Solution Approach 1:
The setting head serves as an intermediary structure that provides a controlled environment for adhesive application. It acts as a protective barrier between the adhesive application process and the external environment, allowing flexibility in application methods while preventing contamination from external sources
Solution Approach 2:
The setting head creates a controlled, contamination-free environment for adhesive application. By confining the application process within the setting head structure, the patent establishes an inert environment that protects the adhesive and functional elements from external contaminants during the critical application phase

AI summary
A device and a method are provided for attaching functional elements (10) made of metal to a component, in particular to a component made of fiber-reinforced plastic, using a setting head (41), the functional element having a contact surface (12) provided with adhesive. In this case, the adhesive inside the setting head is attached to the functional element before the functional element is attached to the component.
