Test method for automobile tire pressure sensor

Abstract

The invention discloses a test method of an automobile tire pressure sensor. The test method comprises the following steps of selecting models, placing a product to be tested in a work station, pressing a starting key of the work station and closing a test cabin cover of the work station; starting a pressurization and heating process of the work station, performing the first time process burning on the product to be tested of the work station, performing the next step if the burning is successful and terminating the process otherwise; performing an RF (Radio Frequency) frequency test on the product to be tested of the work station, performing pressurization and heating, performing the next step if the test is qualified and terminating the process otherwise. According to the test method of the automobile tire pressure sensor, multiple detection functions are integrated, the functions can be detected through only one work station, the internal tire environment under the actual tire working conditions is practically simulated, and accordingly the accuracy of obtained test results is significantly improved and the quality of the product is improved.

Description

Technical field [0001] The invention relates to a method for testing an automobile tire pressure sensor. Background technique [0002] At present, most companies adopt two detection schemes in the production process of automobile tire pressure sensors: one is the traditional detection method, which is divided into various stations according to the product function, and each single device or instrument is manually operated for detection and analysis; the other is simple partial integration Function, still need to manually deal with other more complicated detection and analysis. Both of these two detection schemes have shortcomings: A, the equipment is very large, B, the manual participation is more, each station needs to be individually trained to be proficient in operation, the quality of personnel is high, and neither can simulate the sensor in the car. The actual working environment (high temperature, high pressure) inside the tire. [0003] Furthermore, the sensors to be teste...

Problems solved by technology

[0002] At present, most enterprises adopt two detection schemes in the production process of automobile tire pressure sensors: one is the traditional detection method, which is divided into each station according to the product function, and each single equipment or instrument is manually operated for detection and analysis; the other is simple partial integration. function, still need to manually handle other more complex detection and analysis

There are deficiencies in both of these two detection schemes: A. The equipment is very large, B. There are more manual participation. Each station needs to be trained separately to operate proficiently. The actual working environment inside the tire (high temperature, high pressure)

[0003] Furthermore, the sensors to be tested usually have different models and specifications corresponding to different brands, and the previous detection schemes can only be performed on a separate special tool when activating the product to be tested and reading information, and cannot be linked to the test, which is extremely inefficient
