CCD automatic adjusting mechanism

Abstract

The invention discloses a CCD automatic adjusting mechanism which comprises a main body portion and a control unit. A supporting base plate is positioned on the bottom position, and two main columns are symmetrically arranged on the center of the supporting base plate. A hydraulic adjusting column is installed on the inner side of each main column, a floating plate is fixed on the upper end of each hydraulic adjusting column, and the main columns pass through the floating plate and are connected with the hydraulic adjusting columns. A protective cover is installed on the lower center of the floating plate, and two signal emitters and signal receivers are provided. The signal emitters are respectively installed on the two sides of the bottom of the connection board, the signal receivers are connected with a controller through leads, and the controller is connected with the hydraulic adjusting columns through leads. Compared with the prior art, the CCD automatic adjusting mechanism solves uneven spacing by adding signal receivers and signal emitters. The distance is adjusted automatically, and the hydraulic adjusting columns solve the instability during an adjusting process.

Description

technical field [0001] The invention relates to a CCD automatic adjustment mechanism, which belongs to the field of adjustment mechanism equipment. Background technique [0002] In the prior art, limited by the principles of liquid crystal displays, almost all mainstream liquid crystal displays have a certain "light leakage" problem. Serious "light leakage" problems will affect the quality of the liquid crystal display. Therefore, after the finished product of the liquid crystal display, It is necessary to check whether it leaks light. In the prior art, it is all manual detection. Workers adjust the brightness and contrast of the liquid crystal display to the lowest value. Then, in a dark environment, with a black background, observe the liquid crystal display up and down with naked eyes. Whether there are obvious whitening phenomena on the left and right edges, whether there is light coming through the gaps in the display frame, and finally the workers give corresponding de...

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a CCD automatic adjustment mechanism, which solves the problem of uneven adjustment distance by adding a signal receiver and a signal transmitter, and the hydraulic adjustment column solves the problem of unstable adjustment during the adjustment process. problem, the addition of the controller solves the problem of inconvenient manual control, and solves the problems raised in the above-mentioned background technology through the above method. The present invention is easy to use, easy to operate, fast and accurate in detection, and saves time and effort
