Problems solved by technology

[0005] Due to the difference in the size of the LED, when the wavelength and brightness of the LED are detected at the third test station, if the size of the LED is small, it cannot be in contact with the two sides of the third positioning port and the positioning column, so that the purpose of accurate positioning cannot be achieved. There will still be the situation of tilting the test; if the size of the LED is large, the two sides of the positioning port and the positioning column will squeeze the diode colloid, which will damage the colloid

Abstract

An automatic device of testing machine set for LED consists of a group of material feeding structure formed by vibration disc and material feeding paw set; positioning test structure formed by positioning paw set with a numbers of positioning mouth with elastic component, testing set with polarity probe base for testing LED polarity and frame pin probe base for testing brightness and light wavelength of LED, and positioning terminal; material discharging structure formed by driving gear wheel, belt and a numbers of material discharging base set on belt. The device can avoid colloid damage of LED in test.

Description

technical field [0001] The invention relates to a light-emitting diode testing instrument, in particular to an automatic device for a light-emitting diode testing machine. Background technique [0002] After the LED is packaged, its luminance and light wavelength must be tested to ensure its yield or applicability, and the testing method must use a special LED testing instrument for detection. In recent years, there have been light-emitting diode testing instruments with a high degree of automation and reliable testing accuracy. [0003] The patent No. is 01274956.7, the authorized announcement number is CN 2519906Y, and the patent entitled "automatic device for light-emitting diode testing machine" has just announced a kind of such testing instrument. Please refer to Fig. 1, the patent is realized in this way: it is mainly composed of a group of feeding structure, a positioning test structure and a group of discharging structure, and the feeding structure is made up of the...
