Supply ABB V4550220-0100 inventory model multi communication intelligent module

Description

V4550220-0100 With the rapid development of automobile industry, military industry, heavy industry and other industries, the cutting and processing of 3D sheet metal parts and special profiles in these industries presents a trend of small batch quantification, diversification and high-precision. On the one hand, the robotic laser cutting system composed of industrial robot and optical fiber laser has the characteristics of industrial robot, which can freely and flexibly realize various complex three-dimensional curve processing paths; on the other hand, it uses good flexibility. The V4550220-0100 can transmit laser optical fiber remotely as the transmission medium, which will not restrict the robot’s movement path. Compared with the traditional processing methods, the robot laser cutting system can not only meet the accuracy requirements, but also improve the flexibility of the entire laser cutting system, take up less space, and have higher economy and competitiveness.

2. ABB robot related technologies
The difference between V4550220-0100 and motion control such as spot welding and handling is that laser cutting is based on motion control under continuous process state. In addition to requiring the robot to have high precision of moving points and repetitive positioning accuracy, it also requires high precision of robot motion trajectory, i.e. robot straight line and arc trajectory interpolation. The accuracy and stability of chamfer cutting and small circle cutting in laser cutting can well measure the motion control ability of robot. ABB has developed a series of high-end technologies with its strong R&D strength to meet the needs of the market. The developed True Move and Quick Move technologies can well solve the precision problem of chamfer cutting at high speed, while the Advanced Shape Tuning and Wrist Move technologies can well solve the precision problem of small circle cutting. At the same time, the combination of ABB’s off-line programming simulation software Robot Studio and good human-computer interaction interface Flexpendant and human-computer interface makes the entire laser cutting system easy to operate and manage on the premise of meeting customer technical requirements.
2.1 True Move and Quick Move Technology
As shown in Figure 1, the actual path of a traditional robot is consistent with the programmed path at low speed, but the actual path will deviate from the programmed path when turning at high speed. True Move based on advanced feedforward servo control technology greatly improves the motion control accuracy, solves the problem that the actual motion path of the robot deviates from the programmed path at high speed, and truly realizes what you write is what you get.
As shown in Figure 2, the acceleration of traditional robots remains unchanged during the process of speed rise and fall, and the corresponding time to complete an action beat is also long. Quick Move based on advanced dynamic model control technology can accurately control the acceleration, deceleration and steady speed of the robot, and reduce the action beat time by maximizing the acceleration of the robot at any time.
2.2 Advanced Shape Tuning and Wright Move Technology
The Advanced Shape Tuning software developed by ABB can compensate the axial friction of the robot, and make timely and accurate compensation for the micro jitter, resonance and other situations when the robot is walking along a complex 3D cutting path. These functions are included in the options of the robot. When the customer calls the corresponding function modules, the robot can repeat the programmed path according to the instructions and automatically obtain the friction parameters of each axis.
The first, second and third axes of the robot will not move when cutting, and only the fourth, fifth and sixth axes of the moving end of the robot will move. This avoids the adverse effect of the axis friction on the small circle cutting path when the first, second and third axes move.
2.3 Offline programming simulation and human-computer interaction interface
Robot Studio is an offline programming and simulation software developed by ABB, which can complete almost all robot programming and simulation on computers. As shown in Figure 3, a very realistic simulation can be achieved through Robot Studio, and the actual robot programs and configuration files are used. With the ABB Absolute Accuracy calibration system, the simulation results can achieve high accuracy. Robot Studio can also easily import mainstream CAD format data such as IGES, STEP, CATIA, and then program robots based on these precise data. Using the AutoPath function in the software, the robot position (path) required for tracking the processing curve can be automatically generated within a few minutes, which solves the problem that the complex cutting curve in laser cutting cannot be taught, and greatly saves the programming time.
ABB robot adopts the FlexPendent, a touch-screen teaching device, which is very convenient to use with the rocker and simple button design on the teaching device. At the same time, ABB’s newly developed special cutting operation software has a good human-computer interface for laser cutting. The cutting parameter settings, shaft friction adjustment, I/O monitoring and other interfaces are displayed on the teaching device in graphical and digital forms. The interface is very friendly, which is convenient for users to monitor and operate the system.
3. Relevant application cases
The laser cutting system built by ABB 2600 robot well reflects the relevant technologies of ABB robot in the laser cutting application field. Here is an application case.
3.1 System composition
The external layout and internal layout of the robot laser cutting system are shown in Figure 4 and Figure 5 respectively. The whole system is mainly composed of ABB IRB 2600 robot and MTC750 turntable (Figure 6a), IPG laser and water cooling equipment (Figure 6b), Precitec laser cutting head (Figure 6c) and RIP soot purification equipment (Figure 6d).
1) IRB 2600 robot has the highest positioning accuracy and acceleration among similar products, which can ensure high output and low scrap rate to improve productivity. The cut sheet metal parts are placed on the MTC750 turntable. With the MultiMove function of ABB robot, the robot and turntable can move together and achieve high motion accuracy, thus ensuring the laser cutting accuracy of the workpiece.
