AUBO robot screws bolts efficiently and quickly

"Threaded joints are widely used in industrial production, and the automotive upstream and downstream industry is one of the largest and most demanding markets. Taking automobile engines as an example, the number of threaded fasteners for each engine is often 1,000 to 2,000, and the number of varieties is often as high as 100. There is a close relationship between the engine bolting and tightening process and the safety of the engine and the vehicle, especially with the use of high-speed engines, the reliable connection of bolts is more and more important. ”

　　The case customers shared this time mainly provide engine R&D and production for a well-known brand of car companies, ranking among the top 500 international fortunes. Due to the increase in the customer's business volume, the production line continues to run 24 hours a day, and the production task of 1,400 sets of engines needs to be completed every day, and nearly 10,000 bolts are tightened every day. The production line workers repeat the operation all day long, the operation is boring and monotonous, and there are often shortcomings such as missing screwing and lack of torque, and the difference in bolt tightening will seriously affect the quality of the engine; In addition, employees maintain the same working posture for a long time, which is easy to cause damage to the body, and the output power will also be affected. In order to ensure the quality of installation, the requirements for tightening state and torque accuracy control in the production process are getting higher and higher, and the shortcomings such as leakage and lack of torque caused by the existing human operation industry can no longer meet the production needs. The customer finally decided to use AUBO collaborative robots to replace manual bolt tightening operations to ensure product consistency, improve production power, and unleash the potential of employees.

According to the needs of different stations of the existing production line, AUBO i5 and i10 collaborative robots are selected, with a repeat positioning accuracy of ±0.02mm, and each joint can be completed ± 360° rotation, without dead angles, which can meet the tightening needs of all angles of the engine. Even without the use of a vision system, it is possible to complete the work required for high precision continuously for a long time, and to perform precise screw locking.

AUBO cobots support 10-level collision detection and sensor safety detection, which is safe and reliable, without protection, and can work side by side with people. The use of collaborative robots instead of manual bolt tightening operations not only solves the problems of manual leakage and personnel flow, but also ensures the consistency of products and improves the production quality of the engine.

The customer's existing production line plan has been fixed, the space is limited, and it is impossible to stop production for transformation. Traditional industrial robots cover an area of more than 10 square meters, and AUBO collaborative robots cover an area of only about 1 square meters, which can be sensitively arranged on the basis of non-stop production, and the engine bolt tightening operation can be carried out sensitively in a narrow space, which is the best solution for the upgrading and transformation of the production line.

Since it was put into use at the customer's site in 2018, AUBO cobots have been running smoothly for nearly 3 years since they were put into use at the customer's site for 21 hours a day, successfully replacing the work of two workers, so that the customer's site does not need to stop the line. In addition, AUBO cobot can quickly complete the programming, and when the customer's product is replaced, the program can be quickly replaced and put into a new production task, helping the customer greatly shorten the changeover time, and the investment cost can be recovered in 12 months.

AUBO cobots can provide fast-paced, safe and efficient automation solutions, and more and more upstream and downstream manufacturers of automobiles are actively arranging AUBO cobots to be put into the production line for loading and unloading, installation, screw locking, testing, spraying and other operations, and AUBO will continue to share more mature applications of cobots.
