    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.

    4. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    5. The dimensions of the MISUMI parts in the Data, which can be specifed at 1mm intervals, can be edited under historical data.
    6. 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
    • Test unit that can handle various size workpieces by adjusting the position of inspection probes.
  • Operation
    • Changes the distance between probes (probe mounting brackets) by operating right/left hand lead screws. Depending on which direction the lead screw knob is turned, the probe mounting brackets are closing in or moving out from each other.

Points for use

  • Capable to adjust the probe distance from 2 mm to 22 mm.

Target workpiece

  • Shape: Circuit board
  • Size: W 240 x D 140 mm

Design Specifications

Operating Conditions or Design Requirements

  • External dimensions: W 100 x D 180 x H 74 mm
  • Probe adjustment distance: 2 mm - 22 mm

Required Performance

  • Accuracy: ± 0.1 mm
  • Probe stroke: 2.5 mm
  • Probe load: 50 gf (2/3 stroke)

Selection Criteria for Main Components

  • Linear guide
    • Select a linear guides that can handle the load at the probe contact (initial selection is size 10)
  • Compression spring
    • To remove any backlash

      Backlash is a clearance in a mechanism caused by gaps between the parts.

      when positioning inspection pins and during testing.

Design Evaluation

Verification of main components

  • Select motor based on load moment.
  • Motor selection
    • Conditional values:
    • Motor shaft allowable moment of inertia: 1.25 × 10⁻⁵ kg・ (catalogue value)
    • Reduction ratio: 12.5
    • Load total moment of inertia: 5.8 × 10⁻⁵ kg・ 
      1.25 x 10⁻⁵ x 12.5 > 5.8 x 10⁻⁴ Thus, no problem.
    • t = 1.0 s, N =120 rpm (reduction ratio: 12.5), and J = 5.8 kg・c 
      Load torque T=J x N/9.55 x 10-4 x t , T= 7.3×10-3
    • Allowable torque: 0.98 N・m
      7.3×10⁻³ < 0.98
      ⇒Thus, meeting the condition.

Other Design Consideration

  • Reducing operation force by adopting a fine screw thread.
  • Adopting a scale with 0 at the center to read the distance value.
