Chip anti-reversing apparatus

The utility model provides a chip anti-reversing apparatus, comprising a base provided with a horizontal channel upwards opening. Two ends of the horizontal channel are a product inlet and a product outlet respectively. An anti-reversing detection mechanism and a product positioning mechanism are successively mounted on the base from the product inlet to the product outlet. The anti-reversing detection mechanism comprises a sensor fixing rack fixedly connected with an optical fiber sensor. A detection end of the optical fiber sensor is opposite to the upward opening of the horizontal channel. The product positioning mechanism comprises a product stopping member and a driving mechanism for driving the stopping member to vertically move. The stopping member is provided with a stopping end and a connection end, wherein the stopping end is mounted in the horizontal channel and the connection end is connected with the driving mechanism. The chip anti-reversing apparatus of the above scheme can prevent a T0-series
