Problems solved by technology

[0003] At present, in the manufacturing factory, this function is mainly judged and scanned by humans. The effective information is distributed on both sides of the display screen. Manual operation needs to turn the display screen over, which is difficult to operate and prone to errors and leaving dirty scratches on contact.
Due to the low contrast of the silk screen content of the product and the complex imaging background of the product surface, there has been no stable automatic detection equipment

Embodiment Construction

[0012] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0013] Based on the image processing technology and control technology, the present invention realizes the automatic optical inspection of the screen printing content on the front and back sides of the product, the label of the incoming material, and the content of the finished product label during the production process of the display screen, and binds it with the test information of the main board inside the product. The bound information is packaged and uploaded to the production management software. The production management software records and judges whether the information of each part matches through the data of the upstream process in the database, and then sends it back to the equipment.

[0014] As one aspect of the present invention, an o...

Abstract

The invention provides a display screen optical inspection device which comprises a bottom frame, a supporting frame and a top frame, the top frame is arranged above the bottom frame through the supporting frame, a transparent supporting plate is arranged on the bottom frame, a light source and a bottom camera are arranged below the transparent supporting plate, the top frame is provided with a top camera, and the bottom frame is provided with a test module used for lightening and detecting a display screen to be tested placed on the transparent supporting plate. The device realizes one-time detection of silk-screen content, mainboard test information, incoming material labels and finished product label content, can directly communicate with a production management system, solves the problems that manual detection and code scanning are difficult to operate and easy to make mistakes at present, can improve the production efficiency, reduces errors, and improves the product quality. Products with mismatched information are prevented from flowing downstream to cause confusion of production information, the product quality is improved, the size is small, working sites can be flexibly replaced, labor can be saved, and errors are prevented.

Description

technical field [0001] The invention relates to the field of display screen detection, in particular to a display screen optical inspection device. Background technique [0002] During the production process of the display screen, it is necessary to detect the silk screen content, motherboard test information, incoming material label, and finished product label content, and exchange data with the production management system. [0003] At present, in manufacturing factories, this function is mainly judged and scanned by humans. The effective information is distributed on the front and back sides of the display screen. Manual operation needs to turn the display screen over, which is difficult to operate and prone to errors and leaving dirty scratches on contact. Due to the low contrast of the silk screen content of the product and the complex imaging background of the product surface, there has been no stable automatic detection equipment. Contents of the invention [0004]...
