Ueno Singapore is the authorized distributor in Singapore for Machine Engineering Co., Ltd. (hereinafter referred to as MEG), a specialized manufacturer of FA equipment. From MEG’s extensive lineup of FA equipment, we introduce the features of modular products for automated assembly systems that leverage its unique technologies, focusing on applications such as "pitch change, turning over, gripping, and transporting.”

Proprietary Pick-and-Place Unit with Cam Mechanism
Supports various movements, including pitch change, turning over, gripping, and transporting

MEG, headquartered in Nagano Prefecture, specializes in developing and manufacturing FA equipment units. The company is highly regarded in the industry for its rare adoption of "cam mechanisms*", offering modular units with exceptional performance. By leveraging its proprietary cam mechanism, MEG achieves high speed, precision, rigidity, and durability. Since 2024, Ueno’s overseas branches have become authorized distributors of MEG products, allowing these previously Japan-focused solutions to be actively promoted in global markets.
*Cam mechanism: A mechanical system that converts rotary motion into linear motion or other types of movement through a custom-shaped cam structure.

From MEG's extensive product lineup, we introduce four specialized units based on pick-and-place technology, designed specifically for repetitive operations: Pitch Change, Turn Over, Gripping, and Transporting.

▲ A diverse product lineup supporting eight key types of motion

[Pitch Change] PCU & PCS: Pitch Changer
Minimizes Effort and Time for Pitch Adjustments, Enhancing Work Efficiency with High-Speed and Stable Operation

The PCU Pitch Changer is a versatile unit that leverages cam technology for quick and easy pitch adjustments of workpieces. Specifically designed for pitch changes, it is a unique solution from MEG, rarely found in other manufacturers' offerings.

【Key Features】
・Compact and lightweight design for easy installation and efficient use of space.
・High precision enables transportation to any specified pitch position.
・Custom designs available to meet specific needs, allowing for high-speed movement.
・Choose between motor or pneumatic drive options.
・Achieve a 30-40% cost reduction compared to similar products from other manufacturers, while maintaining equivalent functionality.
・High reliability and stable performance over extended periods.

▲ Rotating the input shaft activates the built-in cam, causing the slider to move at an equal pitch, making it usable at any position

▲ A pickup unit capable of high-speed motion on the Z-axis with shockless operation

▲ Pin replacement demo: A compact body with a width of 30 mm and light operation

[Turning Over] TOU: Turn-Over Unit
Simplifies the Complexity of Pneumatic Actuators While Accurately Flipping Parts at High Speeds

The Turn-Over Unit utilizes a unique method that enables precise part flipping even at high speeds. It addresses the complexities of pneumatic actuators and stability issues at low speeds, making it a versatile solution for a wide range of applications.

【Key Features】
・High-precision cam mechanism and stepping drive minimize vibration, ensuring stable high-speed part flipping.
・Simple control system allows for efficient 180° part turnover.
・Infinite track linear guide and a reliable cam mechanism guarantee a long service life.
・Space-efficient design with shared supply and retrieval positions.
・Simplifies complex processes, offering an effective cost-saving solution.
・Compact design with fewer components, enhancing maintenance efficiency.
・Available with motor or pneumatic drive options.
・Inertial forces do not need to be considered during the design phase.

▲ Turn-over supply (extraction): Simple control ensures reliable turn-over, even with a compact size

▲ Easily turns over small items, including electronic components, up to the size of a mobile phone

[Gripping] MEPAC: Air Gripper / Chuck (Parallel Opening Chuck)
Enhances Automated Assembly Precision with Patented, Accurate Gripping Technology.

The parallel opening chuck is a high-performance, high-quality gripper designed to pursue the "proper gripping" technology essential for automated assembly systems and mechanical design.

【Key Features】
・Cam-based design for high precision, rigidity, and speed.
・Compact design, suitable for sizes as small as a thumb.
・High-speed takt (0.4 seconds) and high precision (±0.01mm) ensure stable operation.
・Inner diameter, outer diameter, and spring clamp can all be installed with a common design.
・Cost savings through the standardization of maintenance parts.
・A single unit can grasp both the inner and outer diameters.
・Single-acting type supports both air clamps and spring clamps.
Large piston diameter provides strong gripping force, even in a compact design.

▲ECO MODEL／AVERAGE MODEL

▲ Reliable supply even with a cycle time of 0.8 seconds when combined with the PPU.

[Transporting] PIU: Pickup Unit
Achieves ultra-fast pickup of delicate workpieces using a one-axis cam unit with adjustable stroke.

The Pickup Unit operates ultra-fast at 0.03 seconds per cycle, gently picking up delicate parts that are prone to shock. Its unique technology eliminates the instability commonly encountered during handovers.

【Key Features】
・ Cam mechanism precisely controls acceleration and deceleration through continuous, constant-speed rotation of the input shaft.
・ Capable of downward, stationary, and upward movement in a single rotation (with built-in sensors for operation confirmation).
・ Energy-efficient operation with a 15W brushless motor.
・ Shockless operation compared to air cylinders and screw-driven systems, reducing deflection at the end of the stroke.
・ Quiet operation with a low noise level of 45dB.
・ Can be used as a simple SCARA robot by combining multiple units.
・ Stroke adjustment is possible, despite utilizing a cam mechanism.

▲ Quickly and precisely handling the retrieval and storage of workpieces from pallets

▲ Perform stable image inspection at the pickup position with high speed and smooth stops.
