The invention discloses an automatic shaping and cutting device for chip carriers and relates to the technical field of electronic information. The automatic shaping and cutting device for the chip carriers comprises a bottom end supporting box, wherein the inner walls of the bottom ends of the two sides of the bottom end supporting box are fixedly connected with first air cylinders through supporting devices, the top end of each first air cylinder is fixedly connected with a first air pressure telescopic rod, and the top end of the bottom end supporting box is provided with a groove; the topends of the first air pressure telescopic rods penetrate the outer walls of the top ends of the bottom end supporting box, extend into the groove and are fixedly connected with a carrier bottom end fixing box through second fixators; and the outer walls of the bottom ends of the two sides of the carrier bottom end fixing box are fixedly connected with rotating wheels through first fixators. The automatic shaping and cutting device for the chip carriers mainly aims at plastic chip carriers, and is simple in structure, low in cost and suitable for production and processing of small and medium-sized factories. Meanwhile, the automation degree of the automatic shaping and cutting device is high, the production efficiency of the plastic chip carriers is greatly improved, and the production cycle is shortened.
