The application of Xindashida Zhongweixing SCARA robots in auxiliary component mounting within the 3C industry.
Project Background
In the mounting process for smartphone assembly, due to the wide variety of auxiliary components—each differing in size—and the high precision requirements for mounting, Zhongweixing’s “FR5215 Suspended SCARA Robot + AVS Vision System” has effectively addressed the challenge of automated and flexible mounting of auxiliary components on the production line, achieving a mounting accuracy of ±0.05 mm. Moreover, Zhongweixing has successfully integrated flying-spot imaging technology into this system, significantly boosting efficiency while maintaining the same level of precision.
About Fly Photography
This project employs the Zhongweixing AVS visual positioning system and incorporates fly-capture technology. Unlike fixed-position photography, when the workpiece being picked up passes above the camera, there’s no need to stop for a photo—instead, the camera captures an image while the robot is still in motion. The system instantly feeds back information on the workpiece’s position and orientation, enabling it to perform secondary correction and adjustment to compensate for any potential workpiece displacement.
How can I achieve fly-by photography?
“When the robot moves into the area of the photo-taking point, its internal algorithm uses high-speed IO signals to trigger the camera, enabling dynamic, uninterrupted photography while simultaneously performing high-speed data logging of the actual photo-taking position. By leveraging the position data returned by the camera and the robot’s high-speed logged position, precise position correction can be achieved.”
Customer needs
● Low efficiency of manual mounting;
● Poor accuracy and poor consistency in manual mounting;
● A wide variety of products requires frequent mold changes.
Xinshida Solution
Proposal Description
The Xinshida Zhongwei Xing lifting SCARA+AVS vision system has been selected for the automated component placement project, replacing manual placement and module assembly.
Scheme advantages
● High mounting efficiency: The 6-nozzle circular arrangement design enables the robot to pick and place multiple components in a single pass, saving time.
● Optimized to the extreme for mounting efficiency: The application of industry-leading flying-camera technology significantly reduces the time required for correction and positioning. Previously, capturing and positioning products on a 6-head pick-and-place machine took at least 3.6 seconds; with flying-camera technology, this time can be reduced to under 1 second.
● High mounting accuracy: By using image-based correction at the pick-up point, fly-scan correction with an inverted-mount camera, and image-based correction at the placement point, the mounting accuracy can be guaranteed to reach ±0.05 mm.
● High compatibility: Compatible with various types of materials and supports multiple feeding methods, such as conventional feeder, electronic feeder, blister trays, and other feeding options.
● Easy model changeover: The Zhongweixing AVS vision system is simple and easy to use. During model changes, you can quickly set up new product templates in just a few simple steps by simply selecting the desired area—making model changes convenient and fast.
Scheme Composition
The automated mounting production platform consists of a highly efficient, precise, and flexible automatic feeding mechanism (featuring multiple feeder units and tray-based feeding), an automatic auxiliary material placement system (comprising the Zhongweixing AR6520 SCARA robot plus multiple AVS vision systems), as well as a discharge conveyor line and fixture boards.
The material handling process for the entire project is divided into four steps:
1. Material Pickup: The SCARA robot picks up modeling clay from the feeder and then moves to the material tray position to take a photo for alignment correction before gripping the shield cover.
2. Fly-photography positioning: The robotic arm performs a fly-photography scan above the inverted camera to perform secondary positioning of the material on the end-effector nozzle.
3. Material feeding correction: Calculate the material feeding correction offset based on the flying-scan data, then apply the modeling clay onto the PCB board, and finally place the shielding cover onto the PCB.
4. Inspection: Use the top camera to re-locate the clay dispensing condition.
The robotic arm used in this application is a SCARA robot from the Zhongweixing AR6520 series, with a payload capacity of 5–10 kg and a working radius of 600 mm. The gripper features six suction cups for easy scalability. In the final application of this process, the repeat positioning accuracy after correction reaches ±0.05 mm.
Q&A
Q: How can I trigger a photo capture at the appropriate location without using external sensors?
A leverages Zhongweixing’s integrated drive-and-control technology advantages to perceive the photo-taking area based on real-time positioning.
Q: During continuous trajectory motion, how can multiple workpieces sequentially passing through the field of view be inspected?
A: Simply teach the robot different flying-pick points based on the positions of the workpieces, and then set up visual templates for each flying-pick point. Adjust template parameters such as exposure settings, and finally transmit all visual data to the robot at once, thereby reducing the complexity of data reception. This also fully highlights the advantages of Zhongweixing’s flying-pick solution.
Q: The above introduction is based on Zhongweixing robots paired with the company’s self-developed AVS vision control system. If a third-party vision system is used instead, can the fly-capture function still be achieved?
A: As long as the visual system meets the required frame rate and supports IO triggering, that’s sufficient.

Project Results
The AR6520+AVS vision system completely replaces manual labor, enabling efficient and high-precision placement of auxiliary components while also supporting flexible production and rapid model changes. The application of fly-scan technology is key to ensuring production efficiency and leverages the long-standing technological strengths of Xindada Zhongweixing in the field of motion control.
Vision gives robots the ability to “see.” New vision technologies, such as high-speed imaging, benefit from Zhongweixing’s continuous iterative optimization of visual system algorithms, enabling close integration between visual perception, control theory, and visual processing to achieve more precise robot control and a variety of real-time operations.
In the future, Zhongweixing will continue to be guided by the demands of intelligent manufacturing, focusing on the R&D of robotic vision solutions to drive the transformation and upgrading of the manufacturing industry.
