The end-of-line unloading manipulator is a semi-automatic device that is assisted by manual operation to complete material handling, positioning or unloading. It is suitable for production scenarios with small batches, multiple varieties or flexible intervention.
1. Core features
Manual dominance: The operator completes the action through a handle, button or directly dragging the manipulator.
Low cost: Compared with fully automatic manipulators, it eliminates complex sensors and programming systems.
Flexible adaptation: It can quickly switch between different workpiece types and is suitable for flexible production needs.
Safety design: It is usually equipped with gravity balance, damping adjustment or power assist device to reduce the operation intensity.
2. Typical structural composition
Robot arm: multi-joint structure (3-5 axes) or simple cantilever type, lightweight material (aluminum alloy/carbon fiber).
End tool: quick change interface, compatible with grippers, suction cups, hooks, etc.
Operation unit: handle, button box or teach pendant, partially supporting force feedback.
Power assist system: pneumatic balance cylinder, spring counterweight or electric assist to reduce the manpower burden.
Basic frame: fixed (ground mounted) or mobile (with pulleys), adaptable to different workstation layouts.
3. Workflow example
Manual positioning: The operator moves the robot to the workpiece position at the end of the production line.
Grab start: Press the handle button to trigger the gripping/adsorption action (pneumatic/electric).
Manual transfer: Drag and drop the workpiece to the target position (tray/test bench) with the help of the power system.
Release reset: Trigger the button again to release the workpiece, and the robot returns to the standby position.
4. Applicable scenarios
Small batch production: such as customized products and sample trial production lines.
Complex workpiece processing: manual assistance positioning is required (such as fragile items and special-shaped parts).
Repair/temporary replacement: emergency plan when the automatic robot fails.
Human-machine collaboration area: mixed use with automation lines to handle exceptions.
5. Typical application cases
Automobile welding line: manual assistance positioning of sheet metal parts to the welding gun station.
Food packaging: manual adjustment of the placement of items in the gift box and then the robot assists in sealing the box.
Laboratory: Remote grabbing and transfer of hazardous samples (high temperature/chemical).
