Flexible high-speed intelligent assembly technology for BIW

The flexible high-speed intelligent assembly technology of body-in-white realizes the flexible high-speed intelligent production of body-in-white by comprehensively using visual guidance, servo positioning, flexible passive trolley, intelligent vehicle switching device, flexible flanging, offline debugging and other technologies.

At present, this technology has been successfully applied to the production line of a joint venture brand and an independent brand, realizing the unmanned production of the whole production line for the first time, which can meet the production of five models in the same line and realize intelligent seamless switching. The annual production capacity reaches 240000 sets (45 seconds/set). From the early planning to the design and development, manufacturing, system integration and commissioning, it is independent and independent research and development. In the production line efficiency, automation, digitalization, intelligent flexibility The application of advanced technology has reached the domestic mainstream level.

High speed conveying system technology for BIW

The developed reciprocating circulating conveying device reduces the single-beat conveying time of BIW to less than 6 seconds; Adopt multi-servo cooperative drive, comprehensively utilize the mechanical hard drive form, assist the motion control unit, and develop two forms of lift in the middle of the vehicle body and lift in the threshold on both sides according to the customer's needs, which have the advantages of high transmission speed, stable walking, high adaptability of multiple vehicles, and small floor space.

In order to improve the utilization rate of robots in the body-in-white welding production line, Ruisong Technology has mastered the technology of the body-in-white high-speed conveying system and developed a reciprocating circulating conveying device to shorten the conveying time; Adopt multi-servo cooperative drive, comprehensively utilize the mechanical hard drive form, assist the motion control unit, and develop two forms of lifting in the middle of the vehicle body and lifting in the threshold on both sides according to the customer's needs, thus forming the advantages of high conveying speed, stable walking, high adaptability of multiple vehicles, and small floor space, greatly reducing the handling time of the workpiece.

Uniqueness:

(1) When used with multi-axis servo body-in-white positioning technology, the workpiece realizes the "height 0 transport" (the body is highly consistent in operation and transport status) mode to improve stability and transport efficiency;
(2) When the width of different vehicle bodies is different, the pneumatic servo structure developed by the company is used to realize flexible collinearity of multiple vehicle types.

Breakthrough:

(1) Compared with the traditional roller bed equipment, the mechanism is simple and the conveying efficiency is high. The precision matching formed by the servo technology combined with the gear rack greatly improves the production efficiency of the line body;
(2) Using servo synchronization technology and transmission structure optimization design, the transmission speed is greatly improved.

Multi-axis servo positioning technology for BIW

This technology is an important technology in the flexible welding production line of automobile body. It can be used for flexible positioning, flexible switching, and cooperation with the flexible handling mechanism of automobile body to realize the flexible production of automobile body.

According to the characteristics of the body-in-white structure, the overall 4-axis NC mechanism has been developed to replace the original 2 sets of 3-axis NC mechanisms, so as to achieve the purpose of flexible sharing of multiple vehicle types with respect to the symmetrical reference of the body, reducing energy consumption by more than 30% compared with the original technology, and improving the space utilization rate; Through PLC programming, multi-axis linkage is realized, and the teaching device and human-machine interface are configured. When the model is increased, the production demand can be met by simple teaching, which greatly reduces the time of new model introduction and the additional cost.

Uniqueness:

(1) Taking full advantage of the symmetry of the body structure, the NC servo mechanism composed of four servo motors completely replaces the original two sets of 3-axis NC mechanisms;
(2) Compared with the original technology, one servo drives two devices to move in the opposite direction at the same time, which effectively improves the stability, solves the synchronization problem, and reduces the equipment and operating costs.

Breakthrough:

By optimizing the structure design, the volume of the equipment is greatly reduced, and the working space of the robot is larger.
