System and method for automatic detection

Abstract

The invention provides a system for automatic detection, which is used for testing an LED state display cresset on a plate to be tested. The system comprises a data reading unit, a testing platform unit, a data processing unit and an output displaying unit, wherein the data reading unit is used for retrieving an image file of the LED state display cresset on the plate to be tested; the testing platform unit is connected with the data reading unit and used for fixing, connecting and testing the plate to be tested; the data processing unit is connected with the testing platform unit and connected with the data reading unit through the testing platform unit to transmit data; and the output displaying unit is connected with the data processing unit and used for displaying output data information. The system and a method for automatic detection have high speed and accuracy and reduce the testing cost when testing the LED state display cresset on the plate to be tested.

Description

【Technical field】 [0001] The invention relates to an automatic detection system and method, in particular to a detection system and method of a light emitting diode. 【Background technique】 [0002] In the application of today's industrial computer products, light-emitting diodes (Light-Emitting Diodes, LEDs are used as additional status display lights) are often used. You can directly understand its current status by distinguishing it from the color, without external instruments or equipment. [0003] However, when the number of LED lights is large or the application of multi-color lights (red, orange, yellow, green), the quality of the test method usually directly affects the test results. Generally speaking, there are two main verification methods for LED lights in factory production testing. The first method is to use manual visual inspection of the test program, which is the most cost-effective and easy to introduce, but the error test rate and test time cost are also h...

[0003] However, when the number of LED lights is large or the application of multi-color lights (red, orange, yellow, green), the quality of the test method usually directly affects the test results

Generally speaking, there are two main verification methods for LED lights in factory production testing. The first method is to use manual visual inspection of the test program, which is the most cost-effective and easy to introduce, but the error test rate and test time cost are also high. Highest

The other is to use an automatic optical inspection system. Although this convenience can reduce the probability of manual mismeasurement and speed up the test time, the cost of building equipment for computer system manufacturers has also increased significantly, and products of different sizes It may not be applicable and needs to be ordered separately, and the function-price ratio is not in line with modern economic benefits
