The "he" in the automation industry is both loved and hated – the absolute precision of robots

------------------------------------

With the development of the computer industry and the progress of science and technology, many production-oriented enterprises have begun to change their thinking and gradually replace labor through automated production lines and automated equipment. Many large and small cities have machinery manufacturing plants of different sizes, about thousands of technical school graduates are involved in them every year, their work content is simple and boring, repetitive work day after day, there is no technical content to speak of, even if they work for many years, they may not accumulate valuable experience, which is cruel for young people. So what are they doing repetitively every day? That's screw screws!

In the production line of the machinery manufacturing plant, the most is the assembly workers, who will produce good spare parts according to the requirements of the assembly in turn, the nature of the work is relatively single. A worker may do the same work in a year, or even screw the same screw, so is it necessary to use labor for such work?

As early as 10 years ago, it may have been necessary, but in today's rapid technological development, screw tightening is already a very easy thing in automated production lines.

Automated production

Now as long as people mention the word "automation", they will immediately think of robots, yes, to solve this kind of problem, the vast majority of automated manufacturers will use robot solutions, but some people have to ask, robots have long been there, is this still a new technology? Wait, here's what we're going to talk about today, and that's the answer.

Robots make automation industry practitioners love and hate. In general, most people have more or less learned about the relevant knowledge of robots through television, short videos, Weibo and other media platforms, including videos of robot work, and can't help but sigh that the work is done in one go, neither complaining nor eating (of course, in addition to electricity), but this is only from the perspective of publicity to shoot videos, only engaged in the automation industry to know how difficult it is.

Q: What is the reason why everyone loves and hates "him"?

A: Absolute precision!

Robot absolute accuracy is also known as absolute positioning accuracy, absolute positioning accuracy refers to the positioning accuracy of controlling the robot to reach the specified coordinate position through the robot teach pendant or offline programming, this accuracy is not big or small, it can be as small as affecting the success rate of 0.1% in the work, so large that the team can miss millions of projects, and its importance can be known.

At present, in the demand for automated production lines, many production lines have very high requirements for accuracy, and some even require the silk level, which can be said to be more than enough for industrial robots, because the absolute positioning accuracy of robots can generally only reach the millimeter level, which will lead to deterrs in some high-precision projects.

The absolute precision of the robot will no longer be a reason for you to back down

After years of experience summary and continuous experimentation, the high-tech R&D team has developed a visual correction technology for robot positioning accuracy, which can be said to be innovative in the current industry.

At present, this technology is mainly used in high-precision visual guidance of automated production lines, including grasping and positioning. Its main outstanding role is that it no longer relies on the absolute positioning accuracy of the robot. At present, the mainstream solutions on the market, whether it is two-dimensional positioning technology or three-dimensional positioning technology, can not avoid the absolute accuracy of the robot, because of the use of visual positioning, so the position of each robot movement is an unknown and unique position (can not be taught in advance), which directly leads to the introduction of the robot absolute accuracy error. And high-tech technology, the three-dimensional technology used to shield more than 80% of the robot absolute accuracy error, coupled with the high-tech basic positioning error, the actual positioning error of the final robot can be guaranteed to ± 0.02mm, which greatly expands the robot application scenario.
