    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.

  • * 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.

Application Overview

Purpose

  • Device capable of welding small size workpieces.
  • Operation steps:
    (1) Horizontal cylinder with a guide advances to clamp a workpiece.
    (2) Vertical cylinder with plate heaters descends.
    (3) The plate heater welds workpieces 1 and 2.
    (4) Vertical cylinder controlled by timer returns to start position.
    (5) Clamp cylinder retracts.

Points for use

  • An automatic mechanism in which the cylinder raises and lowers the heater and retains the workpiece during welding operation.
  • Workpieces are manually inserted and removed by the worker using a dedicated tool (vacuum pad).

Target workpiece

  • Resin case outer dimensions: W40ｘD40ｘH6
  • Film sheet outer dimensions: W36ｘD36ｘｔ0.5

Design Specifications

Operating Conditions or Design Requirements

  • Outer dimensions: W350ｘD250ｘH325
  • Heat welding cylinder stroke: 74mm
  • Workpiece retention cylinder stroke: 17mm
  • Thrust of heat welding cylinder: 235.5N (from manufacturer's catalog)

Required Performance

  • Heater power: 142W

Selection Criteria for Main Components

  • Plate heater
    • Select the size based on heat requirements to weld workpieces and the dimensions of the workpieces.
  • Cylinder with a guide
    • A cylinder with a guide that can withstand the allowable lateral load of 19N is selected.

Design Evaluation

Verification of main components

  • Verify that the selected heater calorific value and cylinder allowable lateral load are sufficient for this application.
  • Heat quantity required for the heater
    • Mass of heated workpiece: 0.725kg (304 Stainless Steel)
    • Specific heat of heated workpiece: 0.11kcal/kg°C
    • Temperature rise: 230°C (heated until the temperature of the heated workpiece reaches 250°C)
    • Heating time: 0.5 h (idling)
    • Heating time: approx. 5sec (workpiece)
    • The workpiece heating time should be determined through trial and error because it depends on the size, thickness, and material of the workpiece.
    • Efficiency: 0.3
    • Calculation formula: power for heater (kw) = mass of heated workpiece (kg) x specific heat of heated workpiece (kcal/kg°C) x temperature rise (°C)/(860 x heating time (h) x efficiency (η)) = 0.142 kW = 142W
  • Cylinder with guide
    • Weight of parts in moving unit: (0.0975kg + 0.0368kg) x 9.8 = 1.302N
      Calculated value is below the allowable lateral load of the selected cylinder.

Other Design Consideration

  • Welding time is controlled by a timer.
  • A heat insulation material is used to prevent the heat of the heater from being transmitted to the upper and lower moving parts.
