Abstract

The invention provides a testing system for keys of an automobile air conditioner controller. The testing system includes an electrical source controller, a pressing robot, a pressure sensor, a pressure calibrator, a data acquisition card and a PC, wherein the electrical source controller is used for controlling the testing system. the pressing robot performs pressing and releasing actions on thekeys of the automobile air conditioner controller; the pressure sensor is used for obtaining pressure value voltage signals of the keys; the pressure calibrator is used for performing linear calibration on the pressure sensor before testing; and the PC is equipped with LabVIEW software to control the pressing action of the pressing robot to display a pressing curve and a releasing curve of the tested keys. The invention further provides a testing method for the keys of the automobile air conditioner controller. According to the testing system and method for the keys of the automobile air conditioner controller, the keys on the automobile air conditioner controller on a production line can be directly subjected to pressing testing to test whether the keys are stuck or interfered or not, online testing of products can be completed without testing errors, the testing efficiency is high, and test results are accurate.

Description

technical field [0001] The invention relates to the field of testing buttons of an automobile air-conditioning controller, in particular to a testing system and a testing method for buttons of an automobile air-conditioning controller. Background technique [0002] At present, with the development of automotive electronic products, customers have higher and higher requirements for the sensory experience of automotive electronic products. The touch components of the car, such as the car air-conditioning controller, the design of the buttons on the car air-conditioning controller is required to be sensitive and non-interfering, which helps to improve the user experience. [0003] The buttons of the existing automotive air-conditioning controller often appear stuck and interfered, which does not meet the design requirements. However, in the existing production line of automotive air-conditioning controllers, due to the large production volume and fast flow, each product is man...
