Solder paste printing visual detection system and method based on SPI detection algorithm

Abstract

The invention provides an SPI solder paste printing visual detection system. The SPI solder paste printing visual detection system comprises an induction system, a feeding system, a detection system, a control system and a control system, wherein the induction system induces and detects whether to-be-detected products are input or not; the feeding system conveys the to-be-detected products to a detected area; the scanning system is used for detecting the products conveyed by the feeding system, and the detection content comprises the printing effect of each welding spot and whether the area and thickness of solder paste are qualified or not; the data storage system is used for storing detection data of the scanning system; the system comprises a feeding system for feeding solder paste, a scanning system for scanning the solder paste, a data statistical analysis system for counting and analyzing data scanned by the scanning system, a PLC motion control system for carrying out operation control on the feeding system and the scanning system, and a computer master control system for controlling the scanning system. The system has the advantages of being high in use precision, high in stability, high in working efficiency and the like, and has great economic value and social value.

Description

technical field [0001] The invention relates to the field of LED detection equipment design, in particular to a solder paste printing visual detection system and method based on an SPI detection algorithm. Background technique [0002] As the most popular light source in today's society, LED is favored by people due to its advantages of energy saving, environmental protection and long life. Energy saving is the most prominent feature of LED lamps. In terms of energy consumption, the energy consumption of LED lamps is one tenth of that of incandescent lamps. One, it is a quarter of the energy-saving lamps. This is one of the biggest features of LED lights. Nowadays, people advocate energy saving and environmental protection. It is precisely because of this feature of energy saving that LED lights are widely used, making LED lights very popular. As we all know, LED pressure welding is a very important process in the production of LEDs. The purpose of pressure welding is to l...

Problems solved by technology

After the LED production is completed, the detection of the LED is a very important link, such as the detection of whether the area and thickness of the solder paste are qualified. At present, there is no very effective equipment in the prior art that can complete this work. Therefore, further research is needed. perfection
