Description

Technical Field

[0001] The utility model belongs to the technical field of chip alignment, in particular to a chip alignment mechanism. Background Art

[0002] With the rapid development of industrial electrification and intelligence, the demand for semiconductor packaged chips has shown explosive growth, and the semiconductor packaged chip testing industry has also entered a period of rapid development. In order to increase production capacity and reduce production costs, automated testing equipment that can simulate the test environment and conduct large-scale performance testing of semiconductor chips has played an increasingly important role in the semiconductor testing industry. Among them, before the test, the chip needs to be sent to the chip test sorting machine for testing through the feeding tray, and after the test is completed, the chip is transported out through the discharging tray. However, for tiny chips, the chip is prone to deviation when it is placed in the placement slot of the tray, resulting in uneven placement of the chip, which causes the test sorting machine to sound an alarm, and the uneven placement of the chip is also prone to cause the chip pins to be squeezed and deformed, resulting in poor chip quality. At present, in the case where the chip is not placed flat in the placement slot, the chip is generally manually leveled after the machine is shut down. However, when the chip is frequently unevenly placed, it is easy to fail to handle it in time by manually re-placing the chip, and frequent shutdowns will seriously affect the production efficiency of the chip.

[0003] However, in the prior art, after the chip is processed, the chip is often straightened by a clamping device, and the clamping plate may easily have a large thrust during the straightening process, which may damage the chip during the chip clamping process. At the same time, after the chip is straightened, when the chip is processed, it is often necessary to take out the chip and place the next chip for work. Therefore, when the chip is taken out manually, it is easy for the chip to be subjected to force and rub against the workbench, which may cause the chip to be damaged.

[0004] In view of this, the present utility model is proposed. Utility Model Content
