Liquid crystal display panel foreign matter detection system

Abstract

The invention discloses a liquid crystal display panel foreign matter detection system. The system comprises a feeding mechanism, a discharging mechanism, a scrap material discharging mechanism, a conveying mechanism, a pressing plate mechanism and a judgment module. According to the liquid crystal display panel foreign matter detection system, liquid crystal display panels to be detected are driven to flow through a first conveyor belt, thereby all the liquid crystal display panels to be detected are sequentially detected through the pressing plate mechanism and the judgment module, pipelining, intelligentization and automation of liquid crystal display panel detection work are achieved, the manpower demand is lowered, detection objectivity is improved, and it is helpful to improve detection efficiency and lower the risk that an inferior-quality product passes detection.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal panel foreign object inspection system. Background technique [0002] With the full popularity of smart phones and the continuous innovation of technology, mobile phone products are characterized by rapid updates, low prices, and strict quality, and the competition among major mobile phone manufacturers is becoming increasingly fierce. In this context, the price will undoubtedly become a powerful weapon to defeat the opponent. Low cost has become an issue that everyone pays more and more attention to. Based on the above, the cost pressure is spread to various mobile phone parts suppliers. [0003] As we all know, the assembly of the backlight has extremely high requirements on the cleanliness of the materials and the environment. As long as the tiny foreign matter is clearly visible to the human eye, it is almost regarded as bad. However, zero ...

AI Technical Summary

Problems solved by technology

However, zero foreign matter control is impossible for any backlight factory. For example, the protective film on each optical film will produce residual glue, sebum residues dropped by production employees, etc. Once defective products flow into the client, after assembling the whole machine, would cause great loss

At present, in the industry, the detection of foreign objects on the light-emitting surface of the backlight mainly relies on human eyes to identify some obvious foreign objects that can be easily found, but a large part of foreign objects are difficult to detect, such as residual glue, sebum residue, and flexible plastic materials. etc. These foreign bodies are small in size and difficult to find, but when they are transported or assembled into the whole machine, they will be affected by external forces and the area will expand, forming a foreign body that is visible to the naked eye.
