Semi Auto SMT Stencil Printing Squeegee Blade Inspection Machine | Scraper Quality Control

In SMT assembly, stencil printing quality directly determines solder joint reliability—and squeegee blade condition is the most overlooked factor in print consistency. Minor edge wear, bending, or chipping can cause uneven solder paste deposition, leading to bridging, voids, and expensive rework.
For electronics manufacturers looking to standardize unreliable manual inspection without full automation costs, Subit’s semi automatic squeegee blade inspection machine delivers a high-precision, cost-effective way to validate scraper quality and reduce print defects.
Core Technical Features (How It Improves Your Inspection Workflow)
1. 00-Grade Marble Platform for Stable Accuracy
The machine is built on a 00-grade high-precision marble table, the industry gold standard for inspection reference surfaces:
- Ultra-low thermal expansion coefficient resists temperature-related deformation, ensuring long-term measurement consistency.
- Precision-ground surface dampens workshop vibration, minimizing human error and improving visual defect detection accuracy.
- Supports squeegee blades from 100mm to 600mm in length.
2. Adjustable High-Brightness LED Backlight
Visibility is critical for manual inspection. Our optimized backlight system:
- Enhances edge contrast of squeegee blades, making micro-wear, nicks, and uneven edges far easier to identify.
- Allows stepless brightness adjustment to match different blade materials and workshop lighting conditions.
3. PLC-Controlled Real-Work Pressure Simulation
Unlike static inspection tools, this machine simulates actual printing conditions:
- PLC-controlled adjustable pressure replicates real working loads, so you can observe blade contact performance and deformation under production-like conditions.
- Delivers stable, repeatable pressure output to standardize inspection criteria across all operators and batches.
4. Intuitive Touch Screen Operation
A 7-inch touch screen (10.1-inch optional) streamlines daily use:
- One-click adjustment of backlight brightness, pressure parameters, and inspection presets.
- Dual Chinese-English interface, suitable for global manufacturing teams.
5. Built-In Data Management for Quality Traceability
Full quality control requires auditable records:
- Manually log inspection results and export data via USB for traceability and quality trend analysis.
- Compare historical test data to track blade wear and schedule replacements proactively.
- Optional MES system connectivity (USB, LAN, RS232) to integrate with your smart factory setup.
6. Compact & Durable for Factory Environments
- Small footprint (L750mm × W610mm × H1350mm) fits easily on production lines, in quality labs, or incoming inspection areas.
- High-grade industrial components reduce maintenance frequency and extend equipment service life.
