COB (chip on board) optical component automatic testing sorting machine

Abstract

The invention discloses a COB (chip on board) optical component automatic testing sorting machine, comprising a cabinet, a conveyor belt, a PLC (programmable logic controller) control system, an image system, a constant-current constant-voltage source system, a spectral analysis system, a data analysis system, as well as a feeding mechanism, a testing mechanism, a discharging mechanism, a classifying and receiving mechanism and a turnplate mechanism which are respectively arranged on the cabinet. The function of the automatic testing sorting machine is to realize auto-feeding and auto-discharging, the parameters such as the wavelength, the voltage drop, the luminous flux and the chromaticity coordinates of the COB optical component can be automatically tested online by sampling the light diffusely reflected through an integrating sphere by controlling the constant-current constant-voltage source system, lighting the COB component, and starting the spectral analysis system, and the automatic classification can be realized in combination with the PLC control system, and a subsequent package mechanism can perform the classified package conveniently; the testing and the sorting of the whole COB optical component are automatically performed, the production efficiency is high, the influence from a plurality of human factor is avoided, the detection precision is high, the labor can be substituted, the labor intensity is reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technology in the field of testing equipment, in particular to an automatic testing and sorting machine for COB optical components. Background technique [0002] In the prior art, the testing machines for COB optical components include: high-power integrated (COB) manual single powder replenishment spectrometer, double-station integration (COB) test powder replenishment spectrometer, and COB semi-automatic spectrometer. [0003] The high-power integrated (COB) manual single powder replenishment spectrometer is a more complete function of the row test powder replenishment spectrometer, which is suitable for single powder replenishment spectrometer, and the splitting speed is 1PCS / 5S. Fixtures can be customized according to different COB optical components for inspection, suitable for integrating COB with different shapes, and basically compatible with visible shapes on the market. It can measure forward voltage, forward cur...

Problems solved by technology

The disadvantage of this method is that the feeding method is very complicated, and each material needs to be made of different trays, which is not compatible

[0006] The above manual testing machine and semi-automatic testing machine loading method are essentially placed manually before testing, which is slow and inefficient, and different types of COB optical components need to be replaced with different fixtures, resulting in high cost
