[0002] Chip electrical performance testing is an important means to ensure chip quality and stable performance. During the production of integrated circuits, chips may have some unstable factors due to processing technology, material quality, etc. Chip electrical performance testing can detect these factors that affect chip performance and eliminate bad chips in time, thereby ensuring chip reliability and stability.

[0003] After the electronic component chips are manufactured, the electrical performance of the chips is tested by an electrical performance tester to sort out the defective electronic component chips in time. At present, the sorting of large-scale electronic component chips after testing is usually done manually according to the test results of the electrical performance tester, and the chips are classified one by one, and the qualified chips are placed in one area and the unqualified chips are placed in another area. However, this manual sorting method has low operating efficiency, especially when facing a large number of chips that need to be sorted, it will consume a lot of time and manpower, with high labor intensity, long sorting cycle, low production efficiency and high cost.

[0005] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0007] The rotating shaft of the sorting disk forms an inclined angle with the horizontal plane of the frame. It can be seen that the sorting disk is tilted on the frame and can rotate. The downward tilted part of the sorting disk is the lower part of the sorting disk, and the upward tilted part of the sorting disk is the upper part of the sorting disk. The number of the above-mentioned sorting blowing mechanism and the discharge collection port can be set according to the actual classification of various electronic components and chips tested, and each discharge collection port is marked to indicate that the discharge collection port is a qualified product, an unqualified product, a higher voltage product or a lower voltage product, etc. Usually, the above-mentioned detection mechanism can be an electrical performance detection machine or other detection equipment.

[0008] During the sorting operation, each chip is transported to the lower part of the sorting disk through the unloading end of the automatic unloading mechanism, and then the sorting disk is driven to rotate at a certain inclination angle through the rotating drive mechanism. As the sorting disk rotates, each chip at the lower part of the sorting disk enters the corresponding positioning groove one by one (one chip is placed in one positioning groove); as the sorting disk rotates, some chips are transferred to the upper part of the sorting disk, and the chips at the upper part of the sorting disk can automatically slide down and return to the lower part of the sorting disk due to the action of gravity, so that each chip is basically accumulated at the lower part of the sorting disk, and the empty positioning grooves at the lower part of the sorting disk are automatically replenished with chips; then, the test end of the detection mechanism detects the passing chips. When the detection is completed, the detection mechanism sends the detection results of each chip to the controller one by one. The controller controls the blowing end of the corresponding sorting blowing mechanism according to the different detection results of each chip to blow the corresponding chip outward into the corresponding discharge collection port.

[0009] In the preferred embodiment, the sorting disc is provided with a plurality of strip-shaped air guide grooves arranged along the circumference of the sorting disc, the strip-shaped air guide grooves are the same in number and correspond one to one with the positioning grooves, each strip-shaped air guide groove extends in the inner and outer directions, the outer ends of each strip-shaped air guide groove are respectively connected with the inner ends of the corresponding positioning grooves, and the blowing ends of each of the sorting blowing mechanisms are respectively directed toward the inner ends of the passing strip-shaped air guide grooves.

The blowing direction of the overlapping blowing mechanism is to blow gradually downward from the outside to the inside. The control output end of the controller is electrically connected to the signal input end of the overlapping blowing mechanism. An overlapping blowing mechanism is arranged at the previous station of the detection mechanism. When two chips stacked up and down happen to be placed in the positioning groove, the chip stacked on top is blown into the empty positioning groove at the bottom of the sorting disk through the blowing end of the overlapping blowing mechanism to prevent the chip to be detected from stacking and affecting the detection of the detection mechanism.

[0012] In a further preferred embodiment, the overlapping blowing mechanism includes a second blowing pipe and a second blowing pump, and the second blowing pipe and the second blowing pump are both installed on the frame.

During the rotation of the sorting disk, the sensing end of the material unloading sensing mechanism continuously detects the lower part of the sorting disk. When the sensing end of the material unloading sensing mechanism senses that there are insufficient chips in the lower part of the sorting disk, the automatic material unloading mechanism is controlled to transport a certain amount of chips to the lower part of the sorting disk, and the chips are replenished for the sorting disk in time for detection.

[0014] In a further preferred embodiment, the material feeding sensing mechanism is a sensing probe.

[0015] In the preferred embodiment, an annular retaining ring is provided on the outer edge of the sorting disk, and the upper surface of the annular retaining ring is higher than the upper surface of the sorting disk. Since the sorting disk is arranged at an angle, the protection of the annular retaining ring can prevent the chips on the sorting disk from sliding down and falling off the sorting disk.

[0016] In the preferred embodiment, the angle of the tilt angle is in the range of 10°-60°. According to actual needs, selecting a suitable tilt angle can make it easier for the chips to slide from the upper part of the sorting plate to the lower part under the action of gravity, which helps to maintain the stability of the chip supply at the lower part of the sorting plate.
