Braid material testing method and testing system

Abstract

A braid material testing method comprises the following testing steps that photoelectric sensing signals on a testing station are obtained, a braid material testing result of a testing unit is obtained and stored, and a robot is started according to the testing result to take and place the tested braid material to a designated area, wherein the taking and placing actions comprise the following two taking and placing actions: if the obtained testing result is an 'OK' signal, starting the robot to place the braid material corresponding to the testing result to a qualified station; and if the obtained testing result is an 'NG' signal, starting the robot to place the braid material corresponding to the testing result to a screening station. The testing unit and the robot are controlled through the testing steps of a PLC control unit, so that the whole uninterrupted testing process of automatic feeding, testing, screening and discharging is achieved, and the problems that an existing LCR digital bridge is low in testing efficiency, feeding, testing and removing of braid materials are poor manually, and the whole discharging process is not controlled are solved.

Description

technical field [0001] The invention relates to the detection field of braiding materials, in particular to a testing method and a testing system for braiding materials. Background technique [0002] All kinds of electronic components of the air-conditioning controller are supplied by external suppliers, and their performance needs to be tested before they are used in production. Among them, the braiding materials generally use digital bridges to test whether their performance is good. At present, the digital bridge used to detect the braiding material is a single test device, which does not have the automatic test function, so the manual test takes a long time. [0003] In order to ensure the quality of braided electronic components and avoid serious quality hazards such as poor welding and chip cracks in the subsequent process, after passing the digital bridge test for the first time, it needs to be aged in an environment of 85°C for two hours and then tested again. There...

Problems solved by technology

[0005] In order to overcome the low efficiency and time-consuming problems of the existing digital bridge test, and to solve the problem of manual feeding, testing, rejecting defective, and uncontrolled feeding of braided materials, the entire process of unloading is out of control, so as to prevent manual missed inspection and non-picking during testing. , error removal and other defects cause abnormal quality problems, the purpose of the invention is in the testing process of the braiding material, by PLC control unit and robot according to the test data of the existing LCR digital bridge tester to realize the braiding material feeding, Automated testing for testing, screening, and blanking
