[0002] LED testing and sorting machines are commonly used LED production equipment, used for testing and sorting after product processing, such as testing the light emission and sorting according to the brightness of the light emission. LED testing and sorting machines are usually equipped with a multi-station rotary unit and a feeding unit. The rotation of the multi-station rotary unit realizes the alternation of loading, testing and unloading, and the feeding unit realizes the transportation and output of materials.

[0003] The more important part of the LED testing and sorting device is the feeding device, which usually uses vacuum suction to transport LEDs. However, due to the small size of LEDs, it is easy for the suction port to not completely correspond to the LED during suction, resulting in the LED falling off during the transmission process. The fallen LED is very likely to be damaged, thereby reducing the product qualification rate and making it inconvenient for testing and sorting. Summary of the invention
