The Application of Yanchuan Motion Controller MP2300 in the Special Arm of Injection Molding Machine2016-10-28
In the modern society of goods, plastic products is a common product in people's lives, so the machine for manufacturing plastic products - injection molding machines are also increasingly appear in various types of factories, with the matching injection molding machine Special mechanical arm has also been more widely used, such special mechanical arm is mainly used to capture the plastic injection molding machine has been formed plastic products, and then placed in accordance with the specified path of plastic products. Mechanical appearance shown in Figure 1.
Injection molding machine for robotic arm according to the type of material, the shape of the material and process requirements, classification is very complicated. We only from mechanical point of view, you can simply put them into a 3-axis robot and 5-axis robot, here is the application of the Yaskawa motion control system 5-axis robot. as shown in picture 2:
The main by the main arm, jib, lead pull, rampant four institutions. The lower end of the main arm is connected with the tray, and is used for grasping the main part of the plastic product. The lower end of the auxiliary arm is connected with the fixture for gripping the material part of the plastic product (material head: extra part of the molding product). Pull pull function is the main arm, jib into the injection molding machine face, then the rampant part of the formed product will be transported to the designated location. 5-axis mechanical arm is mainly used in some products with larger size and complicated product shape. In the previous mechanical arm, the driving force of the cylinder or variable frequency motor to achieve more control part of the use of single-chip to achieve. As these control and drive a low speed action, the accuracy is not high and other shortcomings, replaced by the motion controller and servo motor can be greatly improved after the work efficiency.
Yaskawa Motion Controller MP2300 series has powerful axis control capability. It can control 16 servo axes via MECHATROLINK-II only by MP2300 basic module without adding axis control module. In addition to servo axis, Through the same bus to control the drive, distributed IO, sensors, etc., the bus communication speed can reach 10Mbps, the shortest communication cycle can reach 0.5ms, thus ensuring the master station and the sub-station data exchange between real-time, so as to achieve More excellent control effect. In addition, MP2300 has a powerful PLC function, a large number of input and output modules to choose from, its own PLC function can easily control the system effectively.
In addition, YASKAWA servo motor JUNMA series with multi-power section, a variety of control features, its built-MECHATROLINK-II bus communication module, can not increase the basis of the module with the motion controller MP2300 for easy connection, eliminating the need for A large number of wiring and commissioning work, in addition to its low power with the characteristics of inertia, even in the case of a large load can run smoothly.
Electrical configuration is as follows:
5-axis servo-injection molding machine used in the mechanical arm Yasukawa motion control system, compared to the inverter motor and MCU control system consisting of the following advantages:
1, JUNMA AC servo motor is a synchronous permanent magnet servo motor, compared to induction motors, servo motors smaller, more powerful, more precise positioning, so that the overall robot's efficiency has been greatly improved.
2, the entire electrical system using the MECHATROLINK-II communication bus to connect to achieve the control network, which greatly simplifies the wiring, improve system stability and reduce the probability of failure, reducing the workload of technical staff .
3, Yasukawa motion controller MP2300 not only has the servo axis control function and PLC function, it also has a flexible programming, sequential control ladder language and motion control text language, can easily achieve a variety of complex actions, greatly shorten The preparation of procedures and modify the procedure time.
4, motion controller MP2300 is equipped with a variety of communication interfaces, the interface also provides a variety of communication protocols (MEMOBUS, MODBUS, etc.), you can not programming with a variety of brand touch screen connection.
Finally, the application of the Yasukawa MP2300 control system of the 5-axis robot arm compared to the previous use of single-chip inverter control system, the repeatability of positioning accuracy from 0.15mm to 0.10mm, the implementation of a cycle of no-load time from the original 6 seconds to 4.8 seconds, the machine's overall performance has been greatly improved.
