The invention provides an anti-leakage foreign matter detection machine which comprises a machine body with a detection channel, a detection light emission source installed in the machine body, a first detection light collimation shielding device installed in the machine body and a second detection light collimation shielding device installed in the machine body. The first detection light collimation shielding device is located between the detection light emission source and the detection channel, and the second detection light collimation shielding device is located between the first detection light collimation shielding device and the detection channel. According to the leak-proof foreign matter detector, the multi-stage collimation shielding device design is adopted, leakage of detection light rays can be effectively limited, and particularly, the second detection light collimation shielding device can be closer to the detection channel, so that the detection light rays can be effectively prevented from le
