To prepare for purchasing a visual labeling machine, it is essential to conduct a comprehensive analysis of its requirements, taking into account four dimensions: performance, compatibility, environmental adaptability, and cost-effectiveness. The specific requirements are as follows:

1、 Core performance requirements

1. Accuracy requirements

   • High precision scene(Electronic chips, pharmaceutical labels): Precision within ± 0.05mm is required, driven by a closed-loop servo system or linear motor, and equipped with a grating ruler for real-time feedback.
   • General scenario(Daily chemical products): The accuracy control is within ± 0.3mm, and the stepper motor scheme can meet it.
     Case: The labeling of pharmaceutical freeze-dried powder adopts Basler camera HIWIN screw, and the qualification rate is increased to 99.9%.

2. Speed and stability

   • High speed production line(Beverages, food): 400-1200 pieces per minute, using a rotary labeling machine or SCARA robotic arm, with an acceleration of 10m/s ².
   • Continuous production guaranteeThe MTBF (mean time between failures) of the equipment should be ≥ 8000 hours, and the damping system should suppress vibration to within 5 μ m to maintain stability.

3. Dynamic compensation capability

   • Curved/irregular products (such as cosmetic bottles) require a six degree of freedom sticker head to compensate for position deviation in real-time (response ≤ 10ms).
   • Combining visual positioning with AI algorithms to predict product motion trajectories (such as circular labeling of beverage bottles).

2、 Compatibility between labels and products

1. Label feature adaptation

   Label Type	Equipment Solution	Key technical points
   Thin film/metal foil	Anti static paper separation mechanism	Avoid electrostatic interference that may cause adhesive deviation
   Small tags (<5cm ²)	High resolution CCD (≥ 5 million pixels)	Edge detection algorithms (such as Sobel operator)
   irregular shape	Flexible suction head heat shrink sleeve labeling technology	Adapt to circular and elliptical labels

2. Product form compatibility

   • Rule products(Square box/round bottle): The standard label head is sufficient to meet the requirements.
   • Alien products(Soft packaging, curved parts): Visual positioning of flexible fixtures is required, such as SCARA robotic arm end six axis force sensing.
     Case: The curved labeling of mobile phone batteries adopts a vacuum nozzle array with a pressure control accuracy of 0.1N.

3、 Production environment and industry standards

1. Special environmental requirements

   • Sterile environment(Pharmaceutical): The equipment material needs to be 304 stainless steel, certified by GMP, and supports hydrogen peroxide steam disinfection.
   • Explosion proof scenario(Chemical): The equipment requires ATEX/IECEx explosion-proof certification.
   • Damp/dusty environmentIP67 protection level, oil-free vacuum system.

2. Intelligence and scalability

   • data traceabilityIntegrated MES/ERP interface, supporting QR code binding (such as automotive parts traceability).
   • Future UpgradesReserved IoT module interface, supporting energy consumption monitoring or remote diagnosis.

4、 Cost effectiveness and implementation considerations

1. Investment return analysis

   Device Type	Cost range	Applicable scenarios	ROI cycle
   Economic type (domestic)	¥ 80000 to 150000	Small and medium-sized production	6-10 months
   High end model (imported)	¥ 250000 to 500000	Electronic/pharmaceutical precision labeling	8-15 months

2. Implicit cost control

   • maintenance costChoose modular design (such as quick change sticker heads) to shorten the changeover time to 5 minutes.
   • Energy consumption optimizationThe energy consumption of linear motor drive is 30% lower than that of traditional screw, and the braking energy recovery rate is 85%.

5、 Comparison of Industry Application Differences

Summary and Suggestions

The selection of visual labeling machine should be based onAccuracy speed stabilitySelect technical solutions for the triangle core based on industry characteristics:

1. Test validationTest the dynamic labeling accuracy (such as ± 0.1mm label deviation tolerance) under simulated production line;
2. Supplier EvaluationExamine shock absorption design (amplitude ≤ 5 μ m) and after-sales service response (such as Longhai Huanyu's modular replacement service);
3. Long-term planReserve space for AI upgrades (such as deep learning path optimization) to avoid device technological obsolescence in the short term.
