A kind of polarity identification method during both feet two-color diode bending forming, includes the following steps：
Identify material type, confirmation belongs to double-legged two-color diode, and long-short foot is needed in more than 2.5mm；
Setup test instrument, the test fixture on tester are equipped with inspecting hole, and probe is connected to PLC；
The pin of diode is inserted into test fixture, inspecting hole is stretched into using the probe being connected with PLC, with appearing in
Pin contact in corresponding inspecting hole, one of probe correspond to the vacant locations of short foot, not with the touching of short foot, probe according to whether
The pin of diode is touched, feeds back to the different signals of PLC；
PLC judges the position of length pin according to the signal that probe is fed back to, and sets long foot on a left side, the probe in left side stretches into
Inspecting hole is then connected with long foot, and then only there are one probes and short pin to be connected for the probe on right side, PLC according to feed back to whether conducting
Signal exports and judges that signal gives molding machine circuit, identifies diode pin polarity.
Further, the test fixture includes main body, A probes, B probes, C probes and D probes, the side of the main body
It is the first inspecting hole, the second inspecting hole, third inspecting hole and the 4th inspecting hole of 2.5mm equipped with aperture, first inspecting hole and third are visited
