IDEA NOTE Circuit board contact

An O-ring is used on the roller for contacting the sides and edges of the circuit board.

IDEA NOTE Rollers serve as a width guide

The roller attached with the O-ring is flanged and the flange guides the workpiece in the widthwise direction.

IDEA NOTE Idler

Idler presses the belt from the top, creating proper tensioning between belt and pulleys.

    CAD Data Limitations

    1. Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
      You will need to edit the Data so that it meets your specific design conditions.
    2. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.

      3. * The part in the frame is a sub-assembly unit.

    3. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    4. The Data including the third-part components are made by the Company.

       It is configured so that each sub-assembly unit can be used as it is or edited.

Application Overview

Purpose

  • Purpose: transferring glass circuit boards.
    Operation: Rollers are each attached with an O-ring for proper contact with the sides and edges of the glass circuit boards.

Target workpiece

  • Shape: glass circuit board
  • Size: t0.5 x W300 x D500mm

Design Specifications

Operating Conditions or Design Requirements

  • Outer dimensions: W1200 x D714 x H280mm
  • Transfer speed: 100mm/s

Required Performance

  • Load: workpiece + belt = 50N
  • Widthwise positioning accuracy: ±1mm

Selection Criteria for Main Components

  • A motor that can transfer a load of 50N at a speed of over 70mm/s is selected.

Design Evaluation

Verification of main components

  • The torque of the motor and reducer is verified based on the load torque.
    • Conditional value: pulley diameter D = 0.039m, friction coefficient μ = 0.3, efficiency η = 0.9, gear head efficiency ηG = 0.5, gear ratio G = 81, motor torque TM = 0.32N·m, motor rated rotation speed N = 3000rpm, load M = 50N
    • Load torque: T = F x D/2 x η = μ x M x D/2 x η = 0.3 x 50 x 0.039/2 x 0.9 = 0.33N·m
    • Torque of motor and reducer: G = TM x G x ηG = 0.32 x 81 x 0.5 = 13N·m
      > 0.33N·m = T
      -> There is no problem.
    • Transfer speed: V = N x D x π/G x 60 = 3000 x 39 x π/81 x 60 = 75.6mm/s

Other Design Consideration

  • The conveying system is driven by a single motor.
  • An adhesive rubber roller is installed for dust removal.
