Selection steps

■Mega-pixel CCTV lens selection steps

Determine the application conditions
Camera used, shooting distance (WD), Field of view (Subject), etc.

Calculate the focal length
Focal length (mm) = Shooting distance (WD) x CCD element size / Actual field of view

Temporary selection of compatible lens
Temporarily select a lens with focal distance with approx. calculated value.

Confirmation of required conditions
Verify that the field of view and subject resolution of the temporarily selected lens satisfies the conditions.
If not, consider using auto-extension ring.

IDEA NOTE Workpiece positioning method

Workpieces on work table are positioned from two directions for the grippers to avoid interfering with the work guide.This enables gripper claws to grip the workpiece near the center of gravity.

  • Overall height: 341 mm
  • Up/down stroke: 30 mm
  • Feed stroke: 50 mm

Operating Conditions or Design Requirements

  • Component feed position accuracy: ±0.5

Selection Criteria for Main Components

  • This design has a more compact design footprint than the conventional guided cylinder design by 50%.

Design Evaluation

Verification of main components

  • Select cylinder tube DIA. from load conditions, and select a camera・lens from inspection resolution requirements.
  • Selection of air cylinder tube I.D.
    • App. condition: Horizontal mount
    • Conditional value: Load mass M = 0.5 kg
      Friction coefficient μ = 0.2
      Gravitational acceleration g = 9.8 m/s², then
    • Actual load F = μMg = 0.2 × 0.5 × 9.8 = 0.98N
    • Operating pressure P =0.4 MPa
    • Load ratio η=50%, then
      Required cylinder force F0 = (F / η) × 100 = (0.98 / 50) × 100 = 1.96N
    • Cylinder tube I.D. DO = √(1.274 × FO / P) = √(1.274 × 1.96 / 0.4) = 2.50mm
      → 12mm cylinder I.D. is OK
  • Selection of cylinder with guides I.D.
    • App. condition: Vertical mount
    • Conditional value: Load mass M = 0.21 kg
      Gravitational acceleration g = 9.8 m/s², then
      Actual load F = Mg = 0.21 × 9.8 = 2.06N
      Operating pressure P =0.4 MPa
      Load ratio η=50%, then
    • Required cylinder force F0 = (F / η) × 100 = (2.06 / 50) × 100 = 4.12N
    • Cylinder tube I.D. DO = √(1.274 × FO /P) = √(1.274 × 4.12 / 0.4) = 3.62mm
      → 12mm cylinder I.D. is OK
  • Selection of camera, lens
    • Condition: Inspected subject: Gear Dims 34mm
      : Defects of 0.1mm or larger
    • Selected camera: 1/1.8 inch, 1,920,000 pixels (1600 x 1200)
      From catalog (1/1.8 ≒ 1/2)
      Field of view 42 x 56 (workpiece shape is satisfied)
      WD90mm lens and extension ring are selected.
      ⇒ One pixel = 0.035mm (56mm = 1600 pixels)
      ・0.1mm can be inspected.

Other Design Consideration

  • Cylinder with guides and air slide table are used for moving the components under the guide.
  • If the component is unstable at the lifting position add a component position recognition sensor, to allow for safer transport.
