glass circuit board conveyor 3D 模型

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.
