workpiece specification: φ 34, height 29mm

characteristic

specification and size

overall dimension: 320 × 320 × 341mm

total height: 341 mm

up and down stroke: 30mm

feed stroke: 50mm

specification and size

workpiece feed positioning accuracy: ± 0.5

selection basis of main parts

compared with the ordinary cylinder with guide rod, its cross-sectional area is about 1 / 2, and its size is small.

key points of design

calculation process of main parts

the cylinder diameter is selected according to the workpiece load conditions, and the camera and lens are selected according to the inspection resolution.

select inner diameter of pneumatic linear sliding cylinder

service conditions: horizontal installation

condition value: load weight m = 0.5kg

friction coefficient μ = 0.2

according to the gravity acceleration g = 9.8m/s

actual load f = μ mg = 0.2 × 0.5 × 9.8 = 0.98n

service pressure p = 0.4mpa

according to the load rate η = 50%

required cylinder force f0 = (f / η) × 100 = (0.98 / 50) × 100 = 1.96n

cylinder inner diameter do = √ (1.274 × fo / p) = √ (1.274 × 1.96 / 0.4) = 2.50mm

the inner diameter of the cylinder is 12mm, no problem.

select inner diameter of cylinder with guide rod

service conditions: vertical installation

condition value: load weight m = 0.21kg

according to the gravity acceleration g = 9.8m/s

actual load f = mg = 0.21 × 9.8 = 2.06 n

service pressure p = 0.4mpa

according to the load rate η = 50%

required cylinder force f0 = (f / η) × 100 = (2.06 / 50) × 100 = 4.12n

cylinder inner diameter do = √ (1.274 × fo / p) = √ (1.274 × 4.12 / 0.4) = 3.62mm

the inner diameter of the cylinder is 12mm, no problem.

select camera, lens

condition: check object workpiece: gear profile 34mm

: inspection of unqualified products (above 0.1 mm)

camera selection: 1 / 1.8 1.92 megapixel (1600 × 1200)

1 / 1.8 ≈ 1 / 2,

field of view 42 × 56 (in accordance with workpiece shape)

wd90mm lens selection close up lens.

{0.035mm for 1 pixel (1600 pixels for 56mm)

·0.1 mm can be checked.

key points of structure making and design

the cylinder with guide rod and pneumatic linear slide table are used in the workpiece conveying.

when the workpiece is unstable in the image inspection position (workpiece floating, etc.), the workpiece posture recognition sensor should be added. Stampa Pronta: No
