Haibersen HPS-FT series six-axis force sensor can greatly enhance the advantages of robotic arm assembly

Introduction

The main applications of six-dimensional force in the field include assembly and polishing. How to make full use of six-dimensional force sensors and other perception systems to complete more and more complex tasks in various environments to improve work accuracy, production efficiency and reduce costs has become a research hotspot in the current industry.

In the process of promoting the transformation and upgrading of the traditional manufacturing industry, from pure manual assembly to semi-automatic assembly, and then to the current unmanned factory automated assembly, machines replacing people has always been one of the important projects.

In the assembly of products with large production batches and high assembly precision requirements such as automobiles, watches, welding machines, and components, although manual assembly has the advantages of low cost, rapid scale, and high production flexibility due to the demographic dividend, it also has problems such as difficulty in ensuring product consistency, labor shortage, and uneven worker proficiency.

As the demographic dividend advantage fades, the cost of manual labor has risen, which has had a significant impact on the development of various industries in my country. The role of machine automated assembly in replacing manual labor will become more and more significant. Compared with ordinary automatic assembly machines, the performance and precision of the arm are crucial to improving production efficiency and ensuring product quality. With the help of visual mechanisms for auxiliary assembly, a higher level of production yield can be achieved.

The six-axis force sensor is a special force sensor that can measure the force and torque of an object in three axes in a Cartesian coordinate system. It uses highly sensitive materials and precision mechanical structures inside, which can provide higher measurement accuracy for the robot arm and meet the measurement needs in different scenarios. As a key device for the robot arm to perceive the external environment, the six-axis force sensor is usually installed between the end effector of the robot arm and the robot arm. It is used for the multi-dimensional interactive force/torque between the robot and the environment during operation, and the interactive force/torque is fed back to the robot force, which can greatly enhance the assembly advantages of the robot arm.
