Overhead High-Speed Press Robot

No ground space occupation · Dual-speed linkage · Single servo high-efficiency cycle time

Overhead High-Speed Press Robot

Hanging-type, high-speed translational stamping loading and unloading automation equipment; the core adopts 'single servo + synchronous belt/gear dual-stage linkage,' with the mother arm and child arm stacked in the same direction. The end-effector speed is the sum of the two stage speeds, shortening time consumption and improving cycle rate under the same stroke compared to traditional single-stage arm solutions, significantly enhancing operational efficiency. The entire machine is fixed above the press or on a beam, occupying no floor space, making it suitable for compact production layouts with multiple presses in series.

drive method Single servo motor + precision timing belt / gear dual-stage linkage

Speed Ratio Principle Two-stage moving modules nested, reducing cycle time by half (depending on process and program)

Typical Cycle Time Efficient cycle time of approximately 2–4 seconds/cycle (thinner sheets and small parts can achieve shorter cycles).

Arm Extension Stroke Common adjustable range approx. 1.5～2.5 m (non-standard expansion available)

repeatability positioning PLC + servo closed-loop, repeat positioning accuracy about ±0.02 mm

End effector Vacuum suction cup (sheet metal) / Pneumatic gripper (irregular parts), supports quick change

Installation Method Mounted above the press or beam

Product Details

speed ratio mechanism:In a traditional single-segment arm, the full stroke corresponds to one travel time, with the speed limit constrained by the mechanism. The high-speed solution uses nested two-segment modules and single-drive synchronous actuation; when the main arm moves, the sub-arm slides in the same direction, making the end-effector's combined speed the sum of the main and sub-arm speeds. This significantly reduces cycle time for the same transfer distance. Data example: When the extension is approximately 1.7 m, a single pick-and-place can be as low as approximately 2.3 seconds (subject to actual project commissioning).

Structural Composition:The lifting frame bears the entire machine load and aligns with the production line; the drive unit centers on a single servo, balancing energy consumption and cost; the two-stage telescopic arm mostly uses high-strength aluminum alloy, balancing lightweight design and rigidity; the control system collaborates between PLC and servo drives, supporting multi-axis linkage and cycle time optimization. It can replace manual labor for highly repetitive and high-risk tasks such as loading and unloading, while servo closed-loop control helps reduce impact and positioning errors.

Applications and upgrades:Suitable for multi-station connection of 3 to 8 presses or hydraulic presses, covering processes such as 'blank feeding—drawing—forming—cutting off'; also suitable for high-speed continuous stamping of thin plates and small parts (such as battery shells, terminals, etc.); old production lines can directly replace manual labor, reducing manpower investment per shift; the specific payback period depends on production volume and labor costs.

Solution Description:Transfer stroke, rhythm, and gripper form are customized according to product shape, weight, and press center distance; front-end can be connected to coil unwinding, leveling, feeding machine, or other loading forms; supports safety interlock and extended diagnostic interfaces, special specifications can be customized.
