Automatic SR (Scanning Radiometer) dotting jig

The utility model discloses an automatic SR (Scanning Radiometer) dotting jig which comprises a battery valve and a pneumatic device, wherein the battery valve is connected with a tester through a control interface; and the pneumatic device is connected with the battery valve through an air pipe. The automatic SR dotting jig ensures that the battery valve keeps the air pipe under a closed state when a test of a product does not pass; and the tester transmits a voltage signal to the battery valve when the product test passes, and then, the battery valve conducts the air pipe so that the pneumatic device pushes a dotting head to dot a SR of the product. Therefore, whether the electric test of the product is past can be clearly learnt from the appearance based on whether the SR end of the product is dotted, thereby effectively preventing defective products from going out of a plant.
