However, when the used insertion pins are produced, there are abnormal pins with lengths not meeting the conventional standards due to process defects; however, at present, only manual picking can be used to sort out such abnormal pins, and the efficiency is relatively low; therefore, we propose a probe horizontal detection device to solve the problems mentioned above. Content of the Utility Model

Through vertical distance measurement, the distance from the laser distance sensor to the end of the probe is measured, so as to detect the length of the probe.
