In the ever-evolving world of electronics manufacturing, precision and efficiency are paramount. Mingseal has revolutionized the production of hearing aid components, specifically focusing on the application of its AC100 fully-automatic mounting and precision dispensing machine. This innovative solution addresses the unique challenges faced in mounting sound membranes and shells for inductive components, transitioning from manual labor to an automated process that significantly enhances operational efficiency while effectively controlling adhesive application issues.

The Challenge

The production of medical hearing aid components demands exceedingly high precision and cleanliness. Manual handling often introduces the risk of contamination, such as dust or particles, leading to misalignment, optical loss, and costly rework. Traditional methods struggle to achieve the required sub-millimeter placement accuracy, which can result in failures compromising the final product's performance.

The Root Cause

The primary causes of these issues are inadequate manual handling practices and poorly controlled automated cells. These weaknesses allow particles to infiltrate the cleaning environment, creating small positional errors and resulting in inconsistent adhesive application. Furthermore, with traditional methods, excess glue or misapplied adhesive can lead to performance inefficiencies and costly delays in production.

The Solution

Mingseal's AC100 machine embeds a solution to these challenges by implementing a closed, clean handling cell equipped with a camera-guided unit and precise multi-axis positioning. By offering features such as automatic substrate loading and unloading, precision adhesive dispensing, and inline glue shape inspection, the AC100 ensures repeatable placement while maintaining a pristine assembly environment. The machine is capable of using epoxy glue with eight to twelve dots, each with a diameter of 0.27mm, applied with precision that promotes reliable optical performance.

Moreover, the transition from manual handling to automated processes not only enhances the efficiency of operations but also minimizes human error. The integration of international semiconductor communication protocols and alignment with smart factory MES systems emphasizes the AC100's capability in modern, digitalized manufacturing environments, ensuring that it meets the latest industry standards.

Core Modules of the AC100

• Dispensing Module: Utilizes a linear motor for high-speed, high-precision dispensing.
• Mounting Head: Combines linear motors and DD motors for precision position compensation, enabling accurate component placement.
• Tilting Module: Allows dispensing at angles of ±30°, expanding application versatility.
• Vision Module: Featuring automatic focusing capabilities for height recognition, accommodating products of varying heights.

Successful Implementation in Vietnam

Currently, the AC100 has been successfully implemented in several real-world applications in Vietnam, demonstrating its effectiveness in producing high-quality hearing aid components. This application shows a significant upgrade in productivity and quality assurance, fulfilling the stringent demands of the medical device industry.

Conclusion

Mingseal's AC100 is paving the way for advanced automation in the electronics industry, particularly in the production of hearing aid components. By effectively addressing the issues of manual handling, adhesive application, and component placement accuracy, the AC100 not only enhances operational efficiency but also ensures consistent, high-quality output that meets the rigorous standards of the medical device sector. With proven results in Vietnam, the AC100 stands as a beacon of innovation in an industry that thrives on precision and reliability.
