Problems solved by technology

[0004] However, this common manual detection method is not only difficult to reduce the detection cost due to the high labor cost; moreover, there are quite a lot of variables caused by manual operation during the detection process, such as the uneven force of manual pressing on the fingerprint resulting in the sensing area of ​​the fingerprint Different sizes or different fingerprint clarity will affect the accuracy of detection
[0005] Furthermore, due to the limitation of the shape of the artificial fingerprint, it is difficult to completely cover all the sensing areas on the fingerprint sensor, that is, it is impossible to completely test all the sensing electrodes on the fingerprint sensor.
In addition, common manual detection methods will inevitably lead to contamination of the fingerprint sensor, or even damage to the sensor due to human error or improper application of force

Abstract

The invention discloses a fingerprint sensor detection method and detection equipment. The fingerprint sensor detection method mainly comprises steps that firstly, a fingerprint sensor is provided and is arranged on a test seat; secondly, a press-down mechanism is controlled by a controller for doing press-down movement to approach the test seat, and the press-down mechanism comprises a conductive element; lastly, the conductive element is made to contact the fingerprint sensor on the test seat to detect the fingerprint sensor. The fingerprint sensor detection method is advantaged in that the whole detection process is controlled through utilizing the controller, the press-down mechanism and the conductive element are further utilized to replace a traditional artificial mode to carry out detection, automatic mechanical detection is utilized to replace traditional artificial detection, not only can detection efficiency and detection precision be improved, but also cost can be effectively reduced.

Description

technical field [0001] The invention relates to a detection method of a fingerprint sensor and its detection equipment, more specifically, a method and equipment suitable for fully automatic detection of a fingerprint sensor. Background technique [0002] Fingerprint identification is currently the most common biometric identification method, which mainly utilizes a fingerprint sensor to sense a user's fingerprint and compare it to identify the user's identity. [0003] Furthermore, after the fingerprint sensor is manufactured, the more common quality control inspection is still mainly performed manually. To further illustrate, the detection of the existing common fingerprint sensor is carried out in the following way: first, the testing personnel properly place the fingerprint sensor to be tested in a testing seat, of course, in a factory with a high degree of automation, this step A robotic arm may be used instead of manual labor; then, the inspector presses his finger on...
