Detailed Description 

This ultrasonic welding automation line is specially designed for automotive filter end cap production, 

where plastic components need to be bonded with felt or nonwoven materials.

Compared with manual or semi-automatic production, this system significantly improves welding 

consistency, reduces labor dependency, and ensures stable high-volume output.

The complete automation process includes material feeding, assembly, ultrasonic welding, 

CCD inspection, laser marking, and finished product unloading, forming a closed-loop production system.

Why Ultrasonic Welding for Automotive Filters

Ultrasonic welding is widely used in automotive filtration components because it provides:

• Clean bonding without glue or screws

• Fast cycle time suitable for mass production

• Stable and repeatable welding quality

• Better appearance for visible components

This makes it ideal for plastic end caps combined with felt materials in automotive filter applications.

Automation Line Configuration

The system is built with an 8-station rotary indexing table, allowing multiple processes to operate simultaneously.

Main stations include:

• Feeding stations for plastic and felt

• Assembly and positioning stations

• Ultrasonic welding station

• CCD inspection station

• Laser marking station

• Automatic unloading station

This structure improves production efficiency and ensures consistent process control.

Industrial Control & Components

The automation line uses industrial-grade components to ensure long-term stability:

• PLC control system from Allen-Bradley

• Pneumatic system from SMC

• Electrical components from Schneider Electric

These components help ensure reliable operation in demanding automotive production environments.

• Safety & Noise Control

• The system includes:

• Safety light curtain

• Emergency stop buttons

• Door interlock protection

• Alarm system with tower light

The noise level is controlled within 75 dB, meeting industrial standards.
