Actuator Viscoelastic Member Bonding via Temporary Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for bonding viscoelastic members to actuators using adhesives face efficiency issues due to strong adhesive forces, leading to production and productivity challenges, particularly when separating the conveyance head from the viscoelastic member before the adhesive hardens.
Innovation Solution
A manufacturing method involving a first adhesive layer to bond viscoelastic members to actuator components, where the viscoelastic member is initially adhered to a jig by its own adhesive force, allowing easy separation, and then bonded to the actuator components using a second adhesive layer after hardening, ensuring efficient bonding without movement during separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the viscoelastic member is conveyed by a conveyance head using adhesive, then the viscoelastic member can be positioned and bonded to the actuator components, but the strong adhesive force causes the conveyance head to adhere to the viscoelastic member, making separation difficult and reducing productivity
Solution Approach 1:
The patent applies preliminary action by first bonding the viscoelastic member to a temporary carrier (first jig) using its own adhesive properties before the main adhesive hardens. This preliminary positioning step allows the viscoelastic member to be accurately positioned without requiring strong adhesive forces between the conveyance head and viscoelastic member, enabling easy separation and improving productivity while maintaining positioning accuracy.
2Productivity
If the conveyance head is separated from the viscoelastic member before the adhesive hardens, then the bonding process can proceed, but the viscoelastic member may move during separation due to strong adhesive force, deteriorating manufacturing precision
Solution Approach 1:
The patent introduces an intermediary element (first jig/carrier) that temporarily holds the viscoelastic member during the bonding process. This intermediary allows the viscoelastic member to be separated from the conveyance head easily while preventing movement during the bonding operation, as the intermediary provides a stable platform that maintains positioning accuracy even when separation occurs before adhesive hardening.
3Ease of manufacture
If the adhesive is used to bond the viscoelastic member to both the conveyance head and the actuator components, then the bonding process is simplified, but the strong adhesive force creates harmful adhesion between the conveyance head and viscoelastic member, reducing ease of operation
Solution Approach 1:
The patent segments the bonding process into two distinct stages: first, the viscoelastic member bonds to the temporary carrier (first jig) using its own adhesive properties; second, the actuator components are bonded to the viscoelastic member using the main adhesive. This segmentation eliminates the harmful adhesion between the conveyance head and viscoelastic member while maintaining process simplicity, as each bonding stage uses appropriate adhesive methods for that specific step.

This method enables efficient adhesion of viscoelastic members to actuator components, preventing movement during bonding and ensuring effective resonance suppression, thereby improving production efficiency and maintaining actuator performance.
Implementation Method 1
a viscoelastic member which is adhesively bonded to one side member of a member structuring the support body and a member structuring the movable body by a first adhesive layer
Implementation Method 2
a viscoelastic member such as silicone gel is disposed in a portion where the support body and the movable body are faced each other and a resonance frequency when the movable body is displaced with respect to the support body is controlled by the viscoelastic member to suppress the resonance of the movable body

AI summary
A manufacturing method of an actuator having a support body, a movable body, a viscoelastic member adhesively bonded to one side member of the support body and the movable body by a first adhesive layer, and a magnetic drive circuit structured to relatively move the movable body may include, for adhesively bonding the viscoelastic member to the one side member by the first adhesive layer, a first step in which the viscoelastic member is disposed on a side of one face of a first jig, a second step in which the viscoelastic member and the one side member are overlapped with each other through an adhesive, a third step in which the adhesive is hardened to adhesively bond the one side member and the viscoelastic member to each other by the first adhesive layer, and a fourth step in which the first jig is separated from the viscoelastic member.
