Project Description:
In order to respond to higher-speed, high-performance chip technologies, the linewidth technology of semiconductor processes has continuously evolved to the nanoscale. In the latter stage of the semiconductor manufacturing process, it is therefore necessary to provide a greater amount of output per unit time and a shorter production time. cycle. The products produced by the semiconductor process cover diversification, including flash memory, logic chips, analog chips, etc. In response to the trend of this technology and the market, multiple processes are integrated into a single machine in the semiconductor back-end process. Simplifying the types of machines in process production lines can also significantly shorten the cycle time of the process. Moreover, this integrated production platform must also provide a higher-speed production method and cooperate with image detection to reduce the cost of manual inspection and reduce the error rate, which is also an important consideration. This project is to introduce how to integrate multi-axis synchronous motion control - pick-and-place motion, and then collaborate with image detection to solve the application of equipment manufacturers in the integration of laser typing, inspection and packaging.

system requirement:
Compared with the past, the machine components are mechanical devices with specific functions. In order to meet the needs of integration and high-speed production, it is necessary to integrate many machines with specific functions in the past into new devices, and integrate the work done in the past by multiple stations. For a single machine to complete. At this time, the complexity of the mechanism of the integrated machine is also relatively increased, and the number of motion control axes in the machine platform is also relatively increased, including a stepping motor and a servo motor. To this end, the customer needs for this project are as follows:
Â
Must use industrial computers with more than two cores to meet high-speed calculations and shorten the cycle of control time
Due to the integration of multiple processes in a single device, the number of axis control needs to reach 30 axes, including stepping motors and servo motors
In a limited space, the size of the machine is not allowed to increase because of the integrated features, so the wiring of the controller is a key point that must be considered, not only will affect the time and cost of field wiring, but will also affect the follow-up maintenance work
Up to nearly a thousand points
• In the inspection section, visual inspection must be introduced, and it must be matched with the axis-controlled position comparison and trigger signal function as an accurate high-speed on-the-fly capture.

System Overview:
In response to customer demand, Advantech defines the critical control area for the part with visual recognition, and the non-image recognition part defines the non-critical control area. Most of them are synchronized with the servo motor as the multi-axis synchronization. Moving handling behavior. Advantech proposes centralized motion control configuration for important control areas and integrates the motion and image of his card image capture card. The distributed motion control configuration can provide the advantages of saving wiring for non-important control areas and reduce the size of the controller body. This configuration can effectively reduce the customer's construction cost, and at the same time can take care of the performance concerned. problem.
The centralized mode motion control configuration is based on Advantech's six-axis control motion card PCI-1265 with SoftMotion technology. In addition to providing customized functions for customers' special organizations, it also provides high-speed position ratio and trigger signal output functions. It can continuously trigger his card image capture card to capture images without stopping the movement, and real-timely utilizes the processing power of the industrial computer dual-core processor.
Distributed motion control architecture can provide more streamlined wiring for multi-axis parts. Compared to centralized control, it can reduce the control card to a single communication main card, and subsequent machine maintenance work can also be made easier. easy!
