Abstract

The invention discloses a testing method of LED frame products. The testing method adopts an LED frame product testing system for testing, and comprises the following steps that two material frame bins filled with materials are respectively placed in two material frame lifting mechanisms for feeding, and separation paper is laid between adjacent material frame products; grabbing mechanisms grab and convey the material frame products in the material frame lifting mechanisms correspondingly below the grabbing mechanisms into conveying devices to be conveyed and suck and convey the separation paper into a separation paper storage mechanism of a feeding device, and the two grabbing mechanisms work alternately in sequence; the two conveying devices alternately work in sequence to convey the material frame products, and in the conveying process of the material frame products, the material frame products sequentially pass through a first optical detection device, a second optical detection device and a third optical detection device to be subjected to multiple times of optical detection; and a material receiving device is used for classifying, stacking and collecting the material frame products subjected to optical detection. The testing method of LED frame products has the advantages of being high in automation degree, accurate in test result, and capable of reducing the labor intensity of workers, improving the working efficiency and improving the product yield.

Description

technical field [0001] The invention belongs to the technical field of AOI optical inspection equipment, and in particular relates to a method for testing LED frame products. Background technique [0002] The LED frame needs to be parameter tested during the production process. The existing LED frame product testing process mainly includes loading, testing, and unloading, which has low automation, high labor costs, low work efficiency, and inaccurate test results. [0003] The traditional LED frame loading method is manually grabbing and loading, and the feeding efficiency is low. After the product is taken out manually, the lower layer of the paper needs to be removed. There are two disadvantages in this feeding method: first 1. Manual contact with the product may cause the surface of the product to be oxidized and corroded, affecting product quality; 2. Because the separator paper is thin, the product below may be pressed when the separator paper is taken out, which will d...
