Peeling Blade: Width 8-12 mm, Length 15-25 mm

Component Specifications

Definition

A precision-engineered blade component used in cover tape peeling mechanisms of SMT tape feeders to cleanly separate the protective cover tape from carrier tapes containing electronic components during automated assembly processes.

Working Principle

The peeling blade operates on a shearing principle where its precisely angled edge engages with the interface between cover tape and carrier tape. As the tape advances through the feeder mechanism, the blade applies controlled pressure and angle to initiate and propagate a clean separation along the tape's pre-scored lines, ensuring components remain securely in their pockets while the cover tape is removed.

High-carbon tool steel (AISI D2 or equivalent) with hardness 58-62 HRC, corrosion-resistant coating (TiN or CrN)

Frequently Asked Questions

How often should peeling blades be replaced in tape feeders?

Peeling blades typically require replacement every 50,000-100,000 cycles depending on tape material and operating conditions. Regular inspection for edge wear, chipping, or corrosion is recommended.

What causes poor tape peeling performance with these blades?

Common causes include blade edge wear, incorrect installation angle, contamination buildup, improper blade material for specific tape types, or excessive blade pressure causing tape deformation.
