Screw feeding unit

for parts assemblystepelectronic equipment

Overview
Step feeder feeding units use low-amplitude, short-cycle agitation to transport screws gently, preserving surface coatings and pre-applied threadlockers. They are commonly used where high cleanliness and minimal handling impact are required, for example in battery, motor and electronics assembly lines.

Main functions / highlights

• Step lifting for precise part indexing
• Protection of coated or adhesive-applied screws
• Clean, low-contamination feeding suitable for PCBA and sensitive assemblies
• Stable and reliable continuous operation

Key performance indicators

• Screw feeding rate: 59 pcs/min
• Maximum operational noise: 64 dB
• Maximum screw length accommodated: 25 mm

Product features & advantages

• Designed for high cleanliness scenarios — minimizes dust and contamination.
• Gentle handling to protect coated surfaces or adhesive layers on screws.
• Low vibration amplitude reduces risk of damage compared with vibratory bowls.
• Noise-optimized construction (literature reports values as low as 65 dB in optimized conditions).
• Integrated screw counter for quantity monitoring and process control.
• High output efficiency — stated screw output up to 60 pcs/min under specified conditions.
• Multiple escapement designs available to accommodate varied screw types.
• Durable, wear-resistant components for extended service life.
• Low jamming rate to support uninterrupted automated feeding lines.
