Product Assembly

The machine automatically assembles the following 9 components:

• 2 × Plastic Housings
• 1 × Main Body
• 2 × Silicone O-rings
• 2 × Plastic Washers
• 2 × Wide Retaining Rings

Each component is automatically fed, positioned, assembled, and inspected to ensure consistent product quality.

Machine Features

Fully Automatic Assembly

The entire assembly process is completed automatically, including component feeding, positioning, assembly, inspection, and finished product output.

Linear Transfer Design

Unlike rotary indexing systems, this machine adopts a linear transfer architecture, providing excellent rigidity and stability.

Even for large or heavy products, the robotic grippers maintain a secure grip throughout the entire production process, ensuring reliable operation at every workstation.

High-Speed Production

• Production Capacity:
  Up to 14 finished products per minute

The machine is designed for continuous, stable, high-volume production.

Large Capacity Feeding System

The machine is equipped with:

• Large-capacity feeding hoppers
• Multiple vibratory bowl feeders

These systems provide continuous automatic feeding, significantly reducing manual intervention and enabling long periods of unattended operation.

---

Control System

The machine utilizes internationally recognized automation components, including:

• Siemens PLC
• Siemens HMI Touch Screen
• SICK Sensors
• SMC Pneumatic Components

The combination of these premium components ensures high reliability, precise control, and easy maintenance.

---

Low-Noise Design

To improve the working environment, the machine is equipped with:

• Fully enclosed dust-proof covers
• Sound-insulating enclosure

These features effectively reduce operating noise while protecting internal components from dust and contamination.

---

Alarm Management

The control system provides comprehensive alarm management, including:

• Real-time alarm notifications
• Alarm history records
• Alarm statistics and summaries
• Easy fault diagnosis and maintenance

This enables operators and maintenance personnel to quickly identify and resolve production issues, minimizing downtime.
