Last crawled date: 1 year, 11 months ago
specifications
purpose and action
purpose: to transport glass circuit board.
action: transport the glass circuit board through the contact part of the roller with o-ring.
object artifact
shape: glass circuit board.
specification: t0.5 × w300 × d500mm
characteristic
specification and size
appearance dimension: w1200 × d714 × h280mm
transmission speed: 100 mm / s
accuracy and load
load: workpiece + belt = 50n
position accuracy in width direction: ± 1mm
selection basis of main parts
select a motor that can deliver 50n load at a speed of more than 70mm / s.
key points of design
calculation process of main parts
verify the torque of motor and reducer according to the load torque of workpiece
condition values: pulley diameter d = 0.039m, friction coefficient μ = 0.3, efficiency η = 0.9, efficiency η g = 0.5, gear ratio g = 81, motor torque tm = 0.32n · m, motor rated speed n = 3000rpm, load m = 50n
load torque: t = f × d / 2 × η = μ × m × d / 2 × η = 0.3 × 50 × 0.039 / 2 × 0.9 = 0.33n · m
rated torque of motor and reducer: tg = tm × g × η g = 0.32 × 81 × 0.5 = 13n · m
>0.33n·m=t
there is no problem
transmission speed: v = n × d × π / g × 60 = 3000 × 39 × π / 81 × 60 = 75.6 mm / s
key points of structure making and design
one motor drives two conveyors.
adhesive rubber roller is set for dust removal.
