Research And Design Of Automatic Testing Platform For Solenoid Products Based On PLC Technology

Solenoids play a very important role in the fields of social life,industrial automation control and so on The performance test and guarantee of solenoids are also very important.The research of solenoid testing system can not only detect the quality of solenoid products,but also help to fill the blank of solenoid testing in China.It is of great significance to improve the level of solenoid testing technology and promote the development of automation technology in China.The quality of solenoid products is demanded to be higher,so there are many items to be tested.If the solenoid products are manually tested,it will take more time to measure solenoid products,which will directly affect the production efficiency of solenoid products.Therefore,this paper mainly based on PLC technology for solenoid product automatic detection platform construction,through the realization of solenoid product detection automation,improve the production efficiency of solenoid products.Based on the brief introduction of the solenoid products under test,according to the quality requirements of the solenoid products under test,it is determined that the automatic testing platform of the solenoid products needs to be able to complete the testing of the integrity,suction,Hi-pot,resistance and voltage resistance of the solenoid products under test.According to the actual situation of the solenoid products,the specific solenoid product testing scheme is determined.Based on the requirement analysis of solenoid performance test platform,the overall structure design of solenoid performance test platform is carried out from two parts of hardware platform and software system.Among them,PLC module,mobile platform,mobile platform driver module,voltage tester and touch screen are included in the hardware part of solenoid product automatic testing platform.The software of solenoid product automatic testing platform includes resistance value testing function,voltage resistance testing function,shift operation function,suction and reaction force testing function.And through the development of automatic detection and implementation function of solenoid products,the quality of solenoid products can be automatically detected.Finally,the test accuracy of the solenoid product automatic test platform based on PLC technology can reach 100%,and the solenoid product test efficiency is high,which meets the requirements of the solenoid product automatic test platform design,such as test automation,test accuracy,test speed and so on.
