Core Product Lines Sepro offers a tiered modular approach to automation, ensuring solutions for everything from simple "pick-and-place" tasks to complex, multi-robot manufacturing cells. Cartesian and 6-axis robots for the automotive sector - Sepro Group
Based on industrial robotics terminology, "Sepro" refers to Sepro Group , a major global manufacturer of Cartesian (linear), 3-axis, 5-axis, and 6-axis robots. They are best known for robotic automation for plastic injection molding machines . Here is a detailed technical and commercial breakdown of "Robot Sepro."
Sepro Robotique: Detailed Technical Overview 1. Company Profile & Core Identity
Full Name: Sepro Group (formerly Sepro Robotique) Headquarters: La Roche-sur-Yon, France (Vendée region) Specialization: End-of-arm tooling (EOAT) and high-speed, high-precision Cartesian and articulated robots. Market Niche: Unlike general-purpose robotics, Sepro focuses 100% on the injection molding industry (plastics, rubber, ceramics). They are considered a "Tier 1" player alongside Wittmann, Yushin, and Engel. robot sepro
2. Core Technology: The "Robot Sepro" Ecosystem A "Sepro robot" is not a single machine but a modular ecosystem. It typically consists of: A. Mechanical Structure (Cartesian Dominant)
3-Axis Servo (Standard): X (extract/vertical), Y (transverse/horizontal), Z (demolding/linear stroke). Used for simple pick-and-place (sprue pickers, runners). 5-Axis Servo (High-Performance): Adds two rotary axes on the wrist (pitch/yaw) or telescopic arms for complex angled insert loading/unloading without mold modification. 6-Axis Articulated (Hybrid): Sepro now offers "Strong" series collaborative robots (cobots) and standard 6-axis (e.g., from Yaskawa or Stäubli, integrated under Sepro control). This allows complex trajectories around the mold.
B. Drive & Motion System
AC Servo Motors (all-electric): Sepro pioneered all-electric Cartesian robots. No hydraulics. This provides cleanliness (ISO 7 class cleanroom), energy efficiency (up to 85% less energy than pneumatic), and high repeatability. Linear Guides & Rack/Pinion: High-grade Japanese THK or German Rexroth rails for zero-backlash motion. Max Speed: Typically 2–3 m/s (transverse axis) with accelerations up to 10 m/s². Extraction strokes from 300 mm to over 2500 mm.
C. Control & Software (Visual Control System) The "brain" of a Sepro robot is its Visual Control System (currently V4 or V5).
HMI (Human-Machine Interface): 7-inch or 10-inch color touchscreen with 3D graphical simulation. Programming Paradigm: Two modes: Sepro Group is a premier global manufacturer specializing
Teach Mode: Jog the robot and record positions. Quick Programming (Icon-based): Drag-and-drop actions (Open Gripper → Extract → Move Y → Drop → Core Pull). No text code required.
Sepro’s "Sim con" : A Windows-based offline programming simulator. You design the entire work cell on a PC, test cycles, then upload to the robot. Connectivity:
