Multi-axis servo motion control scheme with visual measurement
In recent years, with the prosperity of smart phone market, mobile phone glass production has gradually become a hot industry. And the glass FE Light Sweep is an important link in the production of mobile phone glass cover. Through the FE Light Sweep link, the glass will be polished, improve the transparency, prepare for the next tempering. With the increasing production demand, the demand of glass machinery is higher and higher. In particular, after the appearance of curved glass ( 5d, 3d ), new requirements for the whole industry automation. And the saoguangji scheme developed by our company realizes the function of automatic up-down material through the mature manipulator and visual system. Working with saoguangji can greatly improve the production efficiency.
Working principle of control scheme
Saoguangji is divided into two sides, meimian four disks, the disc will hold multiple yeju according to certain specifications. The mobile phone glass to be processed is placed on the yeju, fixed on the top by a vacuum adsorption. When saomo is saomo, the disc rotates in the drive of the AC motor. Below is a large rotary table driven by the frequency converter, the rotating direction of the large rotating disk and disc, to control the pressure depth by monitoring the frequency converter current. When the saomo is finished, the machine waits for plane-change to continue running. Both the rise and the trip shaft use jiakong bus servo, high control precision, and it is not easy to appear the problem of left-right imbalance alarm. Up-down material system uses the jiakong four axis manipulator system plus visual system. The reference coordinates and reference angles of each point of the plate are obtained by the teaching benchmark position. In operation, the camera determines the rotation angle of the disc through the black mark point in the image, and obtains the actual position of the current yeju, and generates the trajectory of the up-down material. The manipulator according to these obtained coordinates, from yuanliaokuang and chengpinkuang. In addition, because of the two independent systems, the system coordination and security. The up-down material manipulator system and saoguangji system should limit each other. When the saoguangji needs to change to the saomo or flip the plane-change, the up-down material system requests signal, and when the condition is satisfied, the up-down material system returns the fixed position, and let the saoguangji motion.
Programme performance advantages
1. stable performance, safe and reliable
Using the jiakong motion Bus Topology PLC system, the stability of the whole machine is improved. Solve the original industrial computer system anti-jamming ability, data loss, and other problems. At the same time, with the advantage of jiakong PLC in logic action, strengthen the protection of dongzuojian, improve various alarm, improve the safety of the system.
2. simple operation and convenient maintenance
Simplify teaching steps, reduce the parameters need to be adjusted, more put to the bottom of the system to process. The interface is simple and friendly, convenient terminal customer operation. At the same time, modular programming, integrated bus structure not only increases the stability of the system, but also facilitates maintenance later.
3. faster and higher accuracy
Using jiakong xv5 intelligent camera, collection and processing in one, positioning speed faster, more accuracy. Reduce the waiting time in the photographing positioning process. Using the four manipulator system developed independently, the up-down material is faster, more flexible, and improves the service life of the manipulator, and the positioning accuracy is higher.
4. high degree of integration and strong extensibility
The whole system is independently developed by good company and high compatibility.
