Straight back type test-sorting machine feeding and conveying device for integrated circuit chips

Abstract

The invention provides a straight back type test-sorting machine feeding and conveying device for integrated circuit chips. The straight back type test-sorting machine feeding and conveying device comprises a storing mechanism, a tube pushing mechanism, a tube lifting and overturning mechanism, a middle oblique rail, a rotary feeding mechanism, a test rail, a power source and an industrial personal computer. The tube lifting and overturning mechanism is adjacent to the middle oblique rail. The middle oblique rail is adjacent to the rotary feeding mechanism. The rotary feeding mechanism swings between the middle oblique rail and the test rail in a reciprocating mode. A first chip slipway is arranged in the tube lifting and overturning mechanism. A second chip slipway is arranged in the rotary feeding mechanism. After tubes are conveyed to the tube lifting and overturning mechanism, the tube lifting and overturning mechanism overturns to enable the chips to slide to the middle oblique rail through a tube opening and the first chip slipway; and then the rotary feeding mechanism swings upwards to be connected with the middle oblique rail in a butt-joint mode to receive the chips, and then swings downwards to be connected with the test rail in a butt-joint mode to release the chips. By adoption of the straight back type test-sorting machine feeding and conveying device for the integrated circuit chips, the long-strip-shaped chip tubes can be used as materials for feeding operation, relative postures of the chips in the feeding process can also be fixed, and the space occupied by action of the tubes in the feeding process is small.

Description

technical field [0001] The invention relates to chip processing equipment, in particular to a material feeding and conveying device for an integrated circuit chip straight-back test sorter. Background technique [0002] In the chip processing process, it is often necessary to unpack and load the packaged integrated circuit chip. Since the integrated circuit chip is more precise, it is easily damaged by external force or static electricity. The process link will help reduce the chip damage rate and also help improve the feeding efficiency. [0003] Patent CN203382121U discloses a feeding device for the integrated circuit chip testing and sorting system, which can directly use the chip packaging material tube to load, but in the feeding process of this scheme, the attitude of the chip changes greatly, so that the testing and sorting process has a large impact on the chip introduction. The workload of pin alignment adjustment increases. When the chip is repacked after the test...

[0003] Patent CN203382121U discloses a feeding device for the integrated circuit chip testing and sorting system, which can directly use the chip packaging material tube to load, but in the feeding process of this scheme, the attitude of the chip changes greatly, so that the testing and sorting process has a large impact on the chip introduction. The workload of pin alignment adjustment increases. When the chip is repacked after the test is completed, the packaging material tube needs to be re-aligned to ensure that the packaging posture of the chip in the material tube is correct, which increases the workload and is prone to errors; and in this In the scheme, the space required for the upward movement of the material tube is very large, which may interfere with other equipment in the test and sorting process, resulting in difficulties in equipment installation
