Problems solved by technology

However, the existing liquid crystal panel optical detection system cannot realize automatic lens focusing. In the specific production process, the focus and zoom of the lens are manually performed, resulting in slow detection speed and serious dependence on the operating level of the staff. Otherwise, the captured image is difficult to meet the clarity, resulting in inaccurate detection results

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, the liquid crystal panel automatic focusing optical detection system of this embodiment includes a lens 110, a driving mechanism 120 and a driving controller 130;

[0026] The driving mechanism is connected to the lens in transmission;

[0027] The drive controller generates and outputs a drive signal to control the drive mechanism to drive the lens to focus. The drive mechanism can be a motor drive mechanism such as a motor, a hydraulic drive mechanism, a pneumatic drive mechanism, etc.; the lens usually includes an adjustment ring, and the focus ring is compatible with other parts of the lens (such as multiple pieces of optical glass and fixed parts). Focusing can be realized by relative motion.

[0028] The drive controller judges whether it is necessary to adjust the focus according to the received focus instruct...

Abstract

The invention discloses an automatic focusing optical detecting system of a liquid crystal display panel. The automatic focusing optical detecting system of the liquid crystal display panel is designed to solve the problems that due to the fact that an existing device cannot carry out automatic focusing, detection operation is tedious and detection efficiency is low. The automatic focusing optical detecting system of the liquid crystal display panel comprises a lens, a driving mechanism and a driving controller. The driving mechanism is in transmission connection with the lens. The driving controller generates and outputs driving signals and controls the driving mechanism to drive the lens to carry out focusing. The automatic focusing optical detecting system of the liquid crystal display panel has the advantages of being simple in structure and easily and conveniently realizing automatic focusing, and therefore detection efficiency and detection precision are improved.

Description

technical field [0001] The invention relates to the field of display and the field of machine vision technology, in particular to an automatic focusing optical detection system of a liquid crystal panel. Background technique [0002] The liquid crystal panel optical detection system is an essential and important equipment for optical detection of liquid crystal panels in the production of liquid crystal panel industry. However, the existing liquid crystal panel optical detection system cannot realize automatic lens focusing. In the specific production process, the focus and zoom of the lens are manually performed, resulting in slow detection speed and serious dependence on the operating level of the staff. Otherwise, it is difficult to meet the definition of the captured image, resulting in inaccurate detection results. Contents of the invention [0003] (1) Purpose of the invention [0004] In view of the above problems, the present invention aims to provide an auto-foc...
