Test fixture for detecting PCBA board by using sensor

Abstract

The invention relates to a test fixture for detecting a PCBA (Printed Circuit Board Assembly) board by using a sensor, which comprises: a fixture lower die, a sensor and a voltage signal processing device; wherein the sensor is arranged on the fixture lower die, the voltage signal processing device is connected with the sensor; the upper surface of the fixture lower die is provided with a sensor induction area, and the sensor is arranged below the sensor induction area. According to the test fixture of the invention, the test fixture is provided with the sensor, the sensor is used for sensinga copper-containing area at the back of the PCBA board and sending a voltage signal, and the voltage signal sent by the sensor is processed and judged, so that whether the PCBA board is placed right and in place is determined, therefore, the test fixture has the advantages of accurate test results, simple operation, small volume, capacity for providing precious space for test equipment with high volume requirement due to a simple structure, and convenient and simple installation and erection.

Description

technical field [0001] The invention relates to the field of automatic testing, and more specifically relates to a testing fixture for detecting a PCBA board by using a sensor. Background technique [0002] Usually, in the traditional manufacturing industry, it is a necessary process to test whether the PCBA board is placed in place. In this process, in order to save manpower, time or hardware resources and improve test efficiency, the concept of automated testing is introduced. However, the traditional The test fixture for testing whether the PCBA board is placed correctly requires a mechanical on-position switch, and the volume is relatively large and the cost is high. This test fixture adopts the transmission and reception of the sensor, and processes the voltage signal sent by the sensor receiving end. In order to confirm whether the PCBA board is placed correctly and in place, and this method saves a lot of sensor costs, can further reduce the volume, provides valuable ...
