Fully Automated End Cap and Felt Ultrasonic Welding System

Introduction

This case study presents a custom, fully automated End Cap and Felt ultrasonic welding system, 

designed to meet the high-efficiency and precision requirements of modern production lines. 

The system integrates various automated processes, including material feeding, cutting, welding,

 inspection, and sorting, ensuring optimal product quality and reduced labor costs.

Customer Challenges

The Client faced the following challenges with their manual assembly process:

• Inconsistent quality in welding and assembly

• High labor costs due to manual handling

• Need for precise and automated welding

• Difficulty maintaining high-quality standards with variable manual intervention

• Ensuring low noise levels for production environments

Solution

TIMEAST developed a custom, fully automated ultrasonic welding system that includes

the following key features:

1. Automated Material Handling

• End Cap Vibratory Feeder

   Automatically feeds plastic end caps into the production line with high precision.

• Felt Die Cutting and Conveying

  The system automatically cuts circular felt material and transports it via a conveyor

  belt to the welding station.

  

2. Efficient Production and Precision

• 8-Station Rotary Table

  Maximizes production capacity by continuously rotating and facilitating smooth

  transitions between welding and inspection stations.

  

• Precision Ultrasonic Welding Machine

  Uses advanced ultrasonic welding technology to ensure precise and reliable welding

  of end caps and felt materials.

• Keyence CCD Inspection System

  High-precision inspection system to detect welding defects,ensuring only the highest

  quality products move forward in the production process.

3. Automated Sorting System

• Automated Discharge Mechanism

   Based on the inspection results, products are automatically sorted into different

  containers (OK/NG), reducing human error and ensuring only quality products

  proceed to the next stage.

  

4. Advanced Control and Safety Design

• Allen Bradley PLC Control System

  The entire system is controlled by a robust Allen Bradley PLC, providing reliable

  automation and real-time monitoring of operational status.

  

• HMI for Real-Time Display

  The HMI interface displays real-time equipment status, allowing operators to

  monitor and adjust parameters as needed.

• Safety Features

  The system includes an E-stop button, safety light curtains, alarmindicator lights,

  and an interlock system that halts operations when the doors are open, ensuring

  a safe working environment.

• Noise Control

  The machine operates with a noise level below 75db, meeting the client’s

  environmental and workplace standards.

Key Technical Highlights

• Multi-Station Rotary Design

  Increases production efficiency by enabling continuous work without downtime

  between operations.

• High-Precision Welding

  Combining ultrasonic welding and a CCD inspection system to ensure flawless

  product quality and precise welds.

• Automatic Sorting System

  This reduces manual labor significantly by automatically

  sorting products into OK/NG bins, enhancing productivity and quality control.

• Ergonomic and Safe Design

  The system is designed with operator safety in mind featuring easy-to-access controls

  and ergonomic setup, along with comprehensive safety features.

• Customizable Voltage

  The system can be customized to the required voltage (e.g., 120V) to fit the client’s

  existing power systems.

Customer Feedback

“The custom ultrasonic welding system we received has greatly increased our production

capacity. The precision of the welding and the automated sorting have saved us time and

reduced defects in the final product. The noise reduction and safety features are also a huge

benefit, and the system 

is easy to operate with the real-time display and control.”

—Erick Melendez, Strategic Projects Manager at [Trico Products]

Project Results

• Increased Production Efficiency: Automation improved overall production efficiency by 40%.

• Enhanced Product Quality: The CCD inspection system ensured that the product defect rate

  was reduced to less than 1%.

• Labor Reduction: With automated sorting and welding, the need for manual labor was reduced

  by 50%, optimizing labor costs and production time.
