Chip positioning and aligning device and chip testing equipment

The utility model discloses a chip positioning and aligning device and chip testing equipment. The chip positioning and aligning device comprises a feeding mechanism, a positioning mechanism, an aligning mechanism, a carrying mechanism and an identifying mechanism. The feeding mechanism is provided with a supporting platform used for placing a plurality of stacked chips. The positioning mechanism comprises a limiting part and a first driving mechanism, the limiting part limits the chip in the circumferential direction, and the first driving mechanism drives the limiting part so that the limiting part can move in the circumferential direction of the chip. The alignment mechanism comprises a rotating table, a single chip is placed on the rotating table, and the rotating table can drive the chip to rotate around the central axis of the chip. The carrying mechanism carries one of the multiple chips stacked in the feeding mechanism to the alignment mechanism. The recognition mechanism is used for recognizing Mark
