Abstract
The role of the use of spring tension device volumes made in our lives, the more common, such as a dog lead rope, cleaners, etc. device volumes. Spring tension related to the products performance and quality, the need for testing. Paper discussed the principle of spring testing, design of the spring tension test systems. Designed based on the Panasonic (FpΣ-c32) PLC, Proface touch screen (GP37W2), force sensors FAB-80, the spring tension stepper motor test systems, the design is also used as a touch screen human-machine interface, through the operation of touch screen can be parameter settings, to achieve the control of various functions, but also through the touch screen display the test results and the status of currently running on the system for real-time monitoring.
Key words:spring tension test;PLC; touch screen;Stepping Motor
