The invention provides a needle thrusting structure for grasping an SMC sheet material. The needle thrusting structure comprises a grasping device, wherein the grasping device is composed of a supporting unit, an isolation unit, a material grasping unit and a driving unit, the supporting unit comprises a triangular bracket, two groups of slideways are symmetrically arranged on the inclined planeson both sides of the triangular bracket, the material grasping unit comprises two needle claw assemblies, the driving unit comprises an air cylinder, an output shaft of the air cylinder pushes the twoneedle claw assemblies to be slidably connected to the two groups of slideways, the isolation unit comprises a partition plate, a sensing unit is arranged on the partition plate, and the sensing unitcomprises an infrared sensor. According to the needle thrusting structure, it can be guaranteed that the material delivery precision is higher through an automatic feeding method, the delivery time is greatly shortened, compared with a manual feeding method, the efficiency is effectively improved, the working environment is good, direct high-temperature contact is avoided, and the health of the staff is ensured.
