Full-automatic optical detection machine for LED substrate

Abstract

The invention relates to a full-automatic optical detection machine for an LED substrate. The full-automatic optical detection machine for the LED substrate comprises a machine frame and a power distribution control cabinet. A conveying device is arranged on the machine frame, a detection device which is matched with the substrate (30) is arranged above the middle of the conveying device, and a turnover device is arranged on the left side of the detection device. The turnover device comprises a material obtaining and lifting device. Turnover bases are arranged on the portions, located on the left side and the right side of the material obtaining and lifting device, of the machine frame, turnover moving cylinders are arranged on the turnover bases and connected with turnover motors, the turnover motors are connected with turnover clamping cylinders, and the turnover clamping cylinders are connected with the turnover clamping blocks. According to the full-automatic optical detection machine for the LED substrate, the conveying device which can conduct reciprocating movement is adopted to conduct conveying, the detection device is arranged in the middle of the conveying device, the turnover device which is matched with the substrate on the conveying device is arranged on the left side of the detection device, and therefore turnover of the substrate is achieved through the turnoverdevice, then the detection efficiency is greatly improved, the detected substrate can return to the position where the substrate is placed, and the handling cost of the substrate is greatly reduced.

Description

technical field [0001] The invention relates to the field of LED basic detection equipment, in particular to a fully automatic optical detection machine for LED substrates. Background technique [0002] The application of LED lights is becoming more and more extensive, and the demand is increasing, and the key of LED lights is the LED substrate. There are many welding points on the LED substrate, and the LEDs basically have some matching holes, and there are card slots on the front and rear sides. , and in the production process of LED substrates, it is often necessary to perform optical inspection on the solder joints, that is, to detect whether the solder joints are all in an accurate position through an optical detector. [0003] Most of the existing LED substrate optical inspection equipment uses a conveyor belt as a conveying device, and a detection device is provided above the middle of the belt. The detection device detects the LED substrate on the conveyor belt. Ther...

Problems solved by technology

[0003] Most of the existing optical inspection equipment for LED substrates uses a conveyor belt as the conveying device, and a detection device is installed above the middle of the belt. The detection device detects the LED substrate on the conveyor belt. There are certain defects in using the above-mentioned equipment for detection. , only one surface of the LED substrate can be detected at a time, so two operations are required, which greatly consumes the detection time, increases the handling cost of the substrate, and greatly reduces the detection efficiency
