Automatic sorting and welding equipment for square LEDs

Abstract

The invention discloses automatic sorting and welding equipment for square LEDs. The equipment comprises a sorting box, a lamp groove is formed in the sorting box, a conveying mechanism is arranged in the sorting box, the conveying mechanism comprises a conveying motor embedded in the inner wall of the rear side of the lamp groove, and a conveying motor shaft is controlled by the conveying motor; and an LED lamp can be conveyed through an conveying belt and a conveying plate, positive and negative electrodes of the LED lamp are detected through a wedge-shaped copper block and a light sensor, the positive and negative electrodes of the LED lamp and a damaged LED lamp can be conveniently and rapidly detected, the damaged LED lamp is removed through a push rod, the LED lamp can be conveniently and correctly welded in the next step, and finally the LED lamp is welded to the upper side of a circuit board through a welding module, so that rapid welding of the LED lamp is realized. Due to whole design, the equipment is lower in cost, simple in structure, high in automation degree and suitable for large-area popularization.

Description

technical field [0001] The invention relates to the related field of high-end testing machines, in particular to a square LED automatic sorting and welding equipment. Background technique [0002] LED lights are one of the electronic components widely used in electronic equipment, and are widely used in lighting, indication and other aspects in circuits. Its advantages are low cost and stable performance. The disadvantage is that the withstand voltage range is small, and it is prone to breakdown and damage. LED lights are widely used in dot matrix displays. Because LED dot matrix displays require a large number of LED lights for lighting, so It is required that the failure rate of LED lights welded with LED dot matrix is ​​as low as possible, but there is no product with a failure rate of zero. Therefore, when doing dot matrix welding of LED lights, it is necessary to first inspect the LED lights. Due to the large number of LED lights, one by one Inspection and welding not ...

Its advantages are low cost and stable performance. The disadvantage is that the withstand voltage range is small, and it is prone to breakdown and damage. LED lights are widely used in dot matrix displays. Because LED dot matrix displays require a large number of LED lights for lighting, so It is required that the failure rate of LED lamps for welding LED dot matrix is ​​as low as possible, but there is no product with a failure rate of zero. Therefore, when performing dot matrix welding of LED lamps, it is necessary to first inspect the LED lamps. Due to the large number of LED lamps, one by one Inspection and welding not only waste a lot of manpower and are inefficient, so how to start inspection and welding of LED lights conveniently and efficiently still needs continuous research
