collaborative robots

In the rapidly evolving field of robotics, collaboration between humans and machines has become a game-changer. Collaborative robots, also known as cobots, are designed to work alongside humans in various industrial and service applications, leveraging the strengths of both human intelligence and robotic precision. At the heart of these innovative robotic systems lies a crucial component – the flexible bearing – which plays a pivotal role in enabling safe, smooth, and efficient interactions between humans and cobots.

Understanding Collaborative Robots

Collaborative robots are a relatively new generation of robotic systems that are engineered to operate in close proximity to humans without the need for physical barriers or safety cages. These robots are designed with advanced sensors, control systems, and safety features that allow them to adapt to their surroundings and respond accordingly, ensuring the safety of both human workers and the robot itself.

Cobots are becoming increasingly popular in various industries, including manufacturing, healthcare, and logistics, where they assist human workers in tasks that require precision, repetition, or handling of heavy loads. By combining human dexterity and decision-making capabilities with robotic accuracy and strength, collaborative robots offer numerous benefits, such as increased productivity, improved ergonomics, and enhanced operational flexibility.

The Importance of Flexible Bearings in Collaborative Robotics

Flexible bearings, also known as harmonic drive bearings or wave bearings, are essential components in collaborative robotics applications. These specialized bearings are designed to provide smooth and controlled movements while accommodating misalignments and deflections, ensuring safe and reliable operation in close proximity to human workers.

The selection of the appropriate flexible bearing is crucial for the safe and efficient operation of collaborative robots. Key factors to consider include:

  1. Compact and Lightweight Design: Flexible bearings are designed with a compact and lightweight structure, making them suitable for integration into the lightweight and compact designs of collaborative robots.
  2. High Precision and Stiffness: Despite their flexibility, these bearings offer high precision and stiffness, enabling accurate positioning and controlled movements essential for collaborative robotic applications.
  3. Low Friction and High Efficiency: Flexible bearings exhibit low friction characteristics, resulting in high efficiency and reduced energy consumption, which is crucial for the energy-efficient operation of collaborative robots.
  4. Inherent Compliance: The ability of flexible bearings to accommodate misalignments and deflections contributes to the inherent compliance of collaborative robots, enhancing safety and reducing the risk of collisions with human workers.
  5. Customization Options: Manufacturers offer a wide range of customization options for flexible bearings, allowing for tailored solutions to meet specific performance, size, or material requirements of collaborative robotic systems.

In 2017, LKPB became a supplier of flexible bearings to French **company Collaborative Robots Project

Before 2016, this customer uses the flexible bearing is Taiwan’s TPI brand, after our sales staff’s continuous communication, in January 2017, the customer finally agreed to let us first provide LKPB qualification, introduction, quality management system and other information.

In February 2017, the customer decided to sample our F32 flexible bearings 100 sets, after receiving the customer’s sample list, our company attaches great importance to the business and technical seminars held in a hurry, the sample will be sent to France by international express mail, after the customer continuous uninterrupted 120 hours of testing, the sample passed once, 2018 began to have small batch of orders one after another, after and before the supplier Comparison, our harmonic flexible bearing’s life, warranty, precision and price are highly recognized by customers. From 2019, our company has become a stable and high quality supplier of France** company!
