Description

Transport method and device

The present invention relates to a conveying method and device, in particular to a conveying method and device used for conveying materials after being aligned and aligned to an intermittent rotating flow path.

According to the general chip, due to its fine and precise properties, it usually needs to be transported and inspected at a high speed. This transport and inspection process takes the material of the LED light-emitting diode chip as an example. The finished LED light-emitting diode must pass through It is placed in a vibrating feeder for alignment and orientation, and then output and transported to a turntable with an intermittent rotating flow path, which is transported by intermittent rotation and performs the detection of the luminescence characteristics of the LED light-emitting diode during the intermittent rotation; For the transportation of large LED light-emitting diodes as an example, turret-type transportation is often used as the provision of the rotating flow path. Such turret-type transportation is often extracted from the end of the conveying channel of the vibrating feeder. The area corresponds to the center of rotation of the turret, and a conveying device is arranged between the extraction area and a material placement part on the circumference of the turret. The conveying device is reciprocated linearly conveyed to the vibrating feeder by a suction nozzle under the extracting part.
