Double Lift Multiplier Chain: A Revolution in Efficiency for Vertical Spaces

• ​mechanism of doubling effect​
  Workpiece plate speed multiplication is achieved by the difference in diameter between the roller (diameter D) and the roller (diameter d). The formula is.V_{catch sight of in a doorway (old)}
  = ν_{cable length (= 1}
  × (1 + D/d). For example, when D/d = 1.5, the speed of the work plate reaches 2.5 times the speed of the chain.
• ​Lift Synergy System​
  The transfer machine drives the guiding axis (repeatability ±0.1mm) through the cylinder to achieve vertical transfer of the workpiece board between the upper and lower layers, and synchronises with the PLC control system in real time to avoid backflow congestion.

​II. Vertical space utilisation: from flat conveyance to three-dimensional circulation​

While traditional single-level conveyor lines often take up extra space due to the return of empty boards, the innovation of the double-level lift doubler chain lies in:

• ​Dynamic partition design​
  • ​Production level (upper): Carrying of pallets for assembly, width suitable for 250-400 mm materials (e.g. PCBs).
  • ​Reflux layer (lower): The empty boards are returned to the starting point by means of a lift.Space Utilisation Enhancement 40%​
• ​Closed-loop energy-saving systems​
  • Inverter motor driven chain (speed 0.3-1.5m/s adjustable), energy consumption is reduced by 30% compared with traditional conveying.
  • Aluminium alloy guide rail and engineering plastic roller combination, reduce friction loss

​III. Application Scenario Breakthrough: From Electronic Assembly to Heavy Manufacturing​

The technology demonstrates differentiated advantages in different industries:

​1. Precision electronics manufacturing​

• backingOn-line charged test(Workpiece plate integrated 12V-48V sliding contact line)
• Pneumatic stopper (response ≤ 0.5 sec) ensures micro patch positioning error ≤ 0.3mm

​2. Assembly of heavy automotive components​

• High-strength alloy steel chain (tensile strength ≥800MPa) to carry heavy workpieces such as engines.
• Double-axis independent tensioning system controls chain droop difference ≤2%, preventing runout.

​3. Food and pharmaceutical aseptic environments​

• Closed lubrication module (500 hours/oil fill) to avoid contamination
• Carbon fibre guide (coefficient of thermal expansion ≤ 0.8 x 10-⁶/K) resistant to autoclaving

​IV. Engineering challenges and innovative responses​

​1. Heat distortion control​

In high-temperature scenarios (e.g. chip curing processes), the use ofCarbon fibre composite railsReplaces aluminium alloys and is 5 times more resistant to deformation.

​2. Micronutrient pollution prevention and control​

• High-temperature chain oil (100°C viscosity ≥46mm²/s) for use in clean rooms
• Roller bearings add nanoscale sealing structure

​3. Lift synchronisation accuracy​

​V. Intelligent Evolution: From Conveyor to Data Hub​

The new generation of systems is undergoing a threefold evolution:

• ​State-Aware Networking​
  Embedded tension/temperature sensor group, real-time monitoring of chain health (sudden change of tension >20% will alarm)
• ​digital twin (Twin) collaboration​
  Speed-load modelling (V=ƒ(μ,Q)) for predicting energy efficiency bottlenecks and dynamic speed regulation
• ​Modular Expansion Interface​
  Mechanical/electrical dual-coupling position is reserved to support plug-and-play with AGV or RFID systems.
