Product Overview

This document details various screw feeding and tightening modules designed for collinear production lines, particularly in automotive and industrial applications. The products support multiple screw types including standard screws, hexagon head screws, combination screws, and self-tapping screws.

Product Models and Configuration

• TMH Series: Tightening modules with integral quick-change mechanisms for rapid model changeovers, supporting vacuum stroke lengths H60, H100, H150.
• FDH Series Step Feeders: Screw feeders with capacities ranging from 0.8L to 4L, available in single and dual channel configurations, with optional functions such as scanning code, cleaning, and error-proofing.

Key Features and Advantages

• Quick-Change Mechanism: Enables rapid model changes, reducing tooling costs and allowing independent replacement of wear-prone components.
• Compatibility: Supports a wide range of screw types and sizes (M2 to M8 approximately), including hexagon head and standard screws.
• Vacuum Suction Monitoring: Prevents fastener drops and ensures stable structural integrity during full-system transitions.
• Low Screw Jamming Rate: Achieves a screw jamming rate below 0.02% (2 per 10,000), with spring flat washer screws showing even lower rates.
• Noise Reduction: Special structural design reduces impact noise and vibration, contributing to a cleaner working environment.
• Error-Proofing: Features such as scan code opening covers and long/short screw detection modules enhance operational reliability.
• Clean Operation: No vibration sources minimize debris generation; cleaning modules provide additional dust removal.
• Advanced Control System: Supports expanded communication modes for networked management, intuitive problem positioning, and high accuracy screw length detection (±1 mm).

Technical Specifications

• Power Supply: DC 24V (guest supply 220V/50Hz)
• Rated Air Pressure: Approximately 0.4 to 0.6 MPa
• Air Consumption: Varies by model, typically around 0.8 to 2 m3/min
• Noise Level: Approximately 60-70 dB at 1 meter distance (excluding solenoid valve blowing sound)
• Dimensions: Various sizes depending on model, with height including bracket ranging from approximately 300 mm to 600 mm
• Screw Size Range: Compatible with screws from M2 to M8, with length and diameter parameters specified for each feeder capacity

Product Structure and Operation

The modules include components such as power connectors, IO interfaces, silo interfaces, RS232 interfaces, debugging interfaces, reset buttons, pressure regulators, power switches, manual valves, stands, feeding ports, covers, separators, straight rail tracks, box handles, step pushing units, and signal lights. The design reserves space for screw blowing pipes and allows for easy opening of upper covers for maintenance.

Applications and Use Cases

These screw feeding and tightening modules are optimized for collinear production lines requiring high reliability, efficiency, and quality assurance. They are particularly suited for automotive manufacturing where low screw jamming rates and clean operation are critical.

Summary

The documented screw feeding and tightening systems offer a scalable, versatile, and reliable solution for automated assembly lines. Their advanced features such as quick-change mechanisms, error-proofing, noise reduction, and high compatibility with various screw types make them suitable for modern industrial production environments demanding high precision and minimal downtime.
