Light emitting diode (LED) material supply equipment with automatic polarity detection function

The utility model relates to light emitting diode (LED) material supply equipment with an automatic polarity detection function, which comprises a work table, wherein an LED polarity detector and an LED plug-in module device are arranged on the work table, a controller is arranged under the work table, and a first steam cylinder, a second steam cylinder, a third steam cylinder, a fourth steam cylinder, a fifth steam cylinder, a detection head, a sensor, a picking clamping mechanism and a feeding mechanism are respectively connected with the controller. Through the tight matching of a vibration disc, a linear oscillator, a conveying rail, a material falling opening, a movable plate, the sensor, the detection head, the picking clamping mechanism, the feeding mechanism and all steam cylinders, an LED is sorted by the vibration disc, carries out polarity detection at the front end of the material falling opening arranged on the conveying rail and is then sieved at the material falling opening, the full automatic polarity detection, the sieving and the plugging of the LED on one equipment are realized, and the blank in the field is filled. The LED material supply equipment has the advantages that the structure is reasonable and compact, the cost is lower, the use is convenient, the maintenance is simple, and the LED material supply equipment is suitable for being popularized and applied.
