High-precision rapid positioning device for 3C die cutting product on coil stock

The utility model discloses a high-precision rapid positioning device for a 3C die cutting product on a coil stock. The device comprises a bottom plate and a feeding plate, vacuum suction fixing partsare respectively formed at the front and rear ends of the feeding plate; a sensor is arranged above the vacuum suction fixing part at the front end; the material belt periodically moves at a fixed distance through the winding assemblies on the two sides; the sensor detects salient points of a product to control the material belt to move, the guide rod air cylinder stretches out, the positioning needle ascends to be inserted into a positioning hole of the product, and therefore the product is fixed to a set position, the transverse telescopic part retracts, the longitudinal lifting part descends, the pressing plate moves downwards to press the product, and the vacuum suction fixing parts at the two ends vacuumize and fix the two ends of the material belt. The positioning device has the advantages that mechanical r
