    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 Data including the third-part components are made by the Company.

Application Overview

Purpose

  • Workpiece is bonded in the box by UV curing.

    A technique for curing adhesives or inks by using ultraviolet light.

  • In order to hold the UV emitting LED at a distance and duration required for curing, spring and a stopper is used for positioning.

Points for use

  • Manual mechanism by lever operation
  • Ensure safe UV irradiation operation

Target workpiece

  • Product with wet coating or adhesive.
    External Dimensions: W45 x D70 x H50

Design Specifications

Operating Conditions or Design Requirements

  • External dims.:W200 x D213 x H278(Max.)
  • Door open/close angle: 180°
  • Lever movement distance: 25.5mm

Required Performance

  • Lever operation load: 16.5N

Selection Criteria for Main Components

  • Spring
    • Low spring constant type is selected for light operations.
  • Acrylic plate
    • UV shielding product is selected for operator safety.
  • Magnetic catch
    • Has a sensor to ensure the door is closed.
  • Stopper bolt
    • Urethane tip type is selected to avoid damaging the work piece.

Design Evaluation

Verification of main components

  • Low constant spring is selected to match the assumed lever operation load.
  • Spring load
    • Formula: Reaction force F = kx
    • Assumed operation force (2 pcs. used): 16.5N
    • Assumed deflection in lever operation: x = 27.5mm (set length: 48mm, free length: 50mm), When stroked 25.5mm)
    • Spring constant: k = 16.5 / 2 / 27.5 = 0.3 N/mm is selected.

Other Design Consideration

    • For safety, UV shielding acrylic plate is selected.
    • Magnetic catch with sensor is used for increased safety.
    • Urethane components are used to avoid damaging work pieces.
