Overview:
For a long time, the complete solution of TFT grinding and cleaning system provided by Japanese developers has been the benchmark of the industry, leading the development trend of the industry. Our company sincerely cooperates with customers, with the help of a variety of control system products, with the bus control system as the main line, and with SCARA robot and AVS vision system, we have realized solutions for multiple stations such as loading and unloading of TFT grinding and cleaning machines, trusses, etc. Real-time control of cleaning equipment, the production efficiency can reach 300pcs/h, which can compete with the Japanese control system.
The TFT grinding and cleaning control system solution designed by our company is shown in the following figure:
The loading and unloading station adopts Adtech EtherCAT bus motion control card ADT-6320E to realize the action of loading and unloading materials to be processed and finished materials. At the same time, it can realize real-time start-stop control and real-time alarm display of truss and cleaning equipment at the front end. The buffer output technology is adopted in the loading and unloading process, which can connect multi-stage point control and hardware communication with the SCARA robot, so that the rhythm of the processing process is smooth and efficient, and there is no sense of pause.
The truss station adopts Adtech EtherCAT bus motion controller ADT-1600E to realize the feeding and grinding of the material to be processed and the transportation and extraction of the material to be cleaned. In order to ensure the harmonious process rhythm, it can support up to 6 grinding equipments to produce at the same time.
The two connecting parts of feeding to the truss and assembling the cleaning material and notifying the unloading are completed by Adtech SCARA four-axis robot + Adtech AVS vision system. The raw material is accurately positioned by the AVS vision system, grabbed by the SCARA robot and accurately placed in the designated area of the truss or empty material box, where the visual accuracy is as high as 1/40 pixel, the SCARA repeat progress can reach ±0.015mm, and the combined accuracy can reach ±0.05 mm.
The working area of loading and unloading and the working area of the robot have a high degree of overlap, and the hardware interlocking mechanism is specially adopted to ensure the efficient operation and the safety and reliability of the equipment.
The equipment has been stably produced at the customer's site, and the production efficiency can reach 300pcs/h, which can reach more than 85% of the efficiency of Japanese machines.
