Double-Layer Inspection Machine for Flat Parts

What This Machine Does

For flat parts - O-rings, flat washers and flat miscellaneous parts - the double-layer machine inspects on two levels within one frame. The brochure lists the two-level design together with the throughput range below; it does not explain the internal layout, so treat the 500-2000 pcs/min figure as the verifiable specification and confirm it on your parts. Configuration facts are on the double-layer inspection machine page (/products/double-layer-visual-inspection-machine).

Key Specifications at a Glance

• Machine size: 2570 x 1960 x 1860 mm.

• Inspection targets: O-rings, flat washers, flat miscellaneous parts.

• Dimension range: 6-45 mm.

• Camera configuration: 6-8 cameras for appearance and dimensions (standard rack).

• Dimensional checks: ID, OD, wire diameter, thickness (optional).

• Visual checks: Short shots, pits, blocked holes, cracks, damage, burrs, edge flash, mold residue, flow marks, impurities, scratches, dents, deformation, discoloration, color variation, material mixing, contamination.

• Glass turntable: 800 mm (larger customizable).

• Repeatability: +/- 0.02 mm.

• Efficiency: 500-2000 pcs/min (depends on product size, actual feeding and camera count).

All specifications above come from the Shengyi New Material (Huzhou) Co., Ltd. machine brochure and are confirmed per configuration at quotation.

Why Two Levels

The brochure presents the double-layer machine as the high-throughput option for flat parts: two inspection levels in one frame serve a line where a single level would hold the pace back. The brochure does not explain how the second level raises throughput, so plan with the confirmed figure on your own samples rather than the design rationale.

O-Ring and Washer Inspection: Parts That Fit (and What Does Not)

The brochure scope is O-rings, flat washers and flat miscellaneous parts in the 6-45 mm range; the design is for flat profiles. Tall or non-flat parts do not suit this machine - the standard HZXX-JC01 turntable machine (/posts/hzxx-jc01-single-table-inspection-machine) is the safer platform there. For larger O-rings, the size bands are covered by the medium ring (100-400 mm) (/posts/medium-o-ring-inspection-machine) and large ring (300-1000 mm) (/posts/large-o-ring-inspection-machine) guides - this machine handles the small end of the family.

What the Cameras Check

Six to eight cameras cover appearance and dimensions on the standard rack. Dimensions: ID, OD, wire diameter and optional thickness. Appearance: short shots, pits, blocked holes, cracks, damage, burrs, edge flash, mold residue, flow marks, impurities, scratches, dents, deformation, discoloration, color variation, material mixing and contamination - grouped in practice as surface defects, dimensional defects and material-mix defects. If you are still deciding which of these matter, start with how to define OK/NG defect criteria (/posts/defining-defects-ai-visual-inspection).

Throughput Reality Check

As a high-speed inspection machine for flat parts, the brochure range is 500-2000 pcs/min - with the actual figure depending on product size, actual feeding and camera count. The top of the range reflects small parts, efficient feeding and the configuration to match. Confirm your parts' realistic throughput on samples at quotation rather than planning the line around the maximum.

How It Compares with Other Models

The HZXXS02 dual-table machine (/posts/hzxxs02-dual-table-inspection-machine) inspects both faces of a part by turning it over. The double-layer machine inspects on two levels; the brochure does not state whether parts are flipped or how many faces are imaged - confirm face coverage on samples. The HZXX-JC01 is the general single-level option. Choose the double-layer machine when your parts are flat and your volumes are high.

What to Prepare Before You Ask for a Quote

Prepare: flat-part samples in the 6-45 mm range, the defect types you must catch, your throughput target, and whether you need the optional thickness check. These decide the camera count, the feeding setup, the face coverage and the final throughput confirmation on your parts.

Frequently Asked Questions

What throughput does it reach? 500-2000 pieces per minute depending on product size, actual feeding and camera count - confirmed on your samples.

What does it check? ID, OD, wire diameter and optional thickness, plus short shots, pits, blocked holes, cracks, damage, burrs, edge flash, scratches, dents, contamination and more.

What repeatability does it offer? +/- 0.02 mm on an 800 mm glass turntable.

Which parts fit? O-rings, flat washers and flat miscellaneous parts in the 6-45 mm range; tall or non-flat parts do not suit the double-layer layout.

Does it check both faces? The brochure does not state this - send samples and we confirm which faces the configuration covers.

What is the difference between double-layer and dual-table machines? The HZXXS02 dual-table machine turns parts over to inspect both faces; the double-layer machine inspects two levels of flat parts in one frame. Confirm face coverage on samples for either machine.
