Vision measurement machines, with their non-contact, high-precision, and automated measurement capabilities, are widely applied across multiple industries where strict control of geometric parameters (size, shape, position, flatness, etc.) is critical. Below are their core usage scenarios, categorized by industry, with specific application examples and value points:
The electronics industry demands ultra-high precision for miniaturized components (e.g., chips, connectors, circuit boards), making vision measurement machines indispensable.
Automotive manufacturing requires consistent precision for safety-critical and functional parts, and vision measurement machines support both component production and final assembly checks.
- Engine & Transmission Components:
Measure the inner/outer diameter of cylinder liners, the tooth profile of gears, and the position of bolt holes. Ensures smooth engine operation and avoids oil leaks or gear wear.
- Chassis & Suspension Parts:
Inspect the flatness of brake discs, the bending angle of control arms, and the spacing of shock absorber mounting holes. Critical for driving stability and braking safety.
- Electronic Control Units (ECUs):
Verify the position of connectors on automotive ECUs and the soldering quality of internal components. Prevents malfunctions in systems like anti-lock brakes (ABS) or airbags.
- Assembly Line Quality Control:
Use automated vision systems to check if parts (e.g., door handles, windshield wipers) are correctly installed and aligned, reducing manual inspection errors.
Medical devices (e.g., implants, syringes, diagnostic tools) have strict regulatory requirements (e.g., ISO 13485), and vision measurement ensures compliance and patient safety.
- Invasive Medical Implants:
Measure the surface roughness of artificial joints, the diameter of coronary stents, and the precision of dental implants. Ensures implants fit the human body and avoid tissue damage.
- Disposable Medical Supplies:
Inspect the inner diameter of syringe barrels (to control drug dosage), the seal of IV catheter connectors, and the hole size of surgical suture needles. Prevents drug leakage or infection risks.
- Diagnostic Equipment:
Calibrate the lens alignment of blood glucose meters, the position of microfluidic channels in PCR devices, and the size of test strip reaction zones. Ensures accurate diagnostic results.
Molds are the "mother of industry," and their precision directly determines the quality of injection-molded parts. Vision measurement machines are used for mold manufacturing and part inspection.
- Mold Cavity & Core Inspection:
Measure the depth, width, and surface finish of mold cavities (e.g., for plastic bottle caps or phone cases). Ensures molded parts match design specifications (no underfilling or overflow).
- Injection-Molded Part Quality Check:
Inspect the wall thickness of plastic containers (e.g., cosmetic jars), the warpage of laptop casings, and the position of plastic bosses (for screw mounting). Reduces scrap rates caused by mold wear or process deviations.
- Mold Maintenance & Repair:
After long-term use, measure mold wear (e.g., cavity erosion) to determine when to repair or replace molds, extending mold service life.
Aerospace components (e.g., turbine blades, aircraft fasteners) operate in extreme environments (high temperature, high pressure), requiring ultra-precision measurement to ensure safety.
- Turbine Blade Inspection:
Measure the curved surface profile of aircraft engine turbine blades, the thickness of blade edges, and the position of cooling holes. Ensures blades can withstand high temperatures and avoid fatigue fractures.
- Aircraft Fasteners:
Verify the thread pitch of bolts, the flatness of washer surfaces, and the alignment of rivet holes. Prevents loosening of structural components during flight.
- Avionics Components:
Inspect the size of radar antenna parts, the spacing of circuit boards in flight control systems, and the flatness of display screens. Ensures reliable operation of navigation and communication systems.
This industry produces high-precision tools (e.g., cutting tools, gauges) and mechanical parts, where vision measurement ensures tool accuracy and part interchangeability.
- Cutting Tool Inspection:
Measure the tip radius of end mills, the flank angle of drills, and the wear of tool edges. Ensures consistent machining quality (e.g., no rough workpiece surfaces due to dull tools).
- Gauge Calibration:
Calibrate precision gauges (e.g., micrometers, calipers) using vision measurement machines, ensuring the gauges themselves provide accurate readings for subsequent inspections.
- Mechanical Component Assembly:
Check the alignment of gear shafts, the clearance between bearings and housings, and the flatness of pump diaphragms. Ensures smooth operation of machinery (e.g., no noise or leakage).
Compared to traditional contact measurement tools (e.g., calipers, micrometers), vision measurement machines excel in:
- Non-contact measurement: No damage to soft/fragile parts (e.g., medical catheters, semiconductor chips).
- High efficiency: Simultaneous measurement of multiple parameters (e.g., size + position + flatness) in seconds, suitable for mass production lines.
- Automation: Integratable with production lines for 24/7 online inspection, reducing manual labor and human error.
In summary, wherever high-precision, efficient, and non-destructive measurement is required, vision measurement machines become a core quality control tool.
