Pressure device

Abstract

The invention relates to the technical field of liquid crystal panel manufacturing, in particular to a pressure device which is used for improving the percent of pass of liquid crystal panels in a press fit process. The invention discloses a pressure device comprising a static pressure plate, a dynamic pressure plate, pressure sensors, driving devices and a control device, wherein the dynamic pressure plate is arranged above the static pressure plate and is composed of a plurality of movable press blocks, the pressure sensors are respectively arranged on each of the movable press blocks, driving devices are respectively arranged corresponding to each the movable press blocks, and each driving device is fixedly connected with a movable press block and drives the corresponding movable press block. The control device is respectively connected with each driving device and each pressure sensor in a signal mode, according to pressure values detected by each of the pressure sensors, the control device judges a big or small relationship between the pressure values and a setting pressure value, outputs pressure adjustment signals to the corresponding driving devices, and adjusts the pressure values between the movable press blocks and the static pressure plate to the setting pressure value.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel manufacture, in particular to a pressurizing device. Background technique [0002] At present, in the manufacturing process of the liquid crystal panel, after the array substrate and the color filter substrate are combined to form a liquid crystal panel, the liquid crystal panel needs to be pressed to make the cell gap of the liquid crystal panel meet the design requirements. [0003] Such as figure 1 As shown, it is a structural schematic diagram of a pressurization device in the prior art, and the pressurization device includes: a base 10, a bracket 20 located above the base 10, a motor 30 fixed on the bracket 20, and one end connected to the motor 30 The transmission mechanism 40, the supporting plate 50 connected to the other end of the transmission mechanism 40, the dynamic pressure plate 60 fixedly installed on the supporting plate 50, and the static pressure plate 70 opposite ...

AI Technical Summary

Problems solved by technology

[0004] However, with the wear and aging of the dynamic pressure plate 60 and the static pressure plate 70, the parallelism between the dynamic pressure plate 60 and the static pressure plate 70 has problems, so that when pressing, the pressure on each area of ​​the liquid crystal panel is uneven. That is, some areas are subject to high pressure, and some areas are under less pressure, resulting in defects such as the thickness of the sealing glue line and the thickness of the box, which affects the pass rate of the LCD panel in the lamination process.
