Embodiment Construction
[0014] Examples, please refer to Figures 1 to 3 , a multifunctional automatic box adjustment device, including a PLC control module 1, a pressure control module 2, a digital display pressure gauge 4 and a pneumatic control module 3.
[0015] The PLC control module 1 is used to convert the pressure value fed back by the digital display pressure gauge 4 into a pressure switching signal, and send a time signal within a preset time, thereby controlling the action of the pneumatic control module 3 . It specifically includes Xinjie TH765-N touch screen 11 and Xinjie XC3-32R-EPLC12. When working, Xinjie TH765-N touch screen 11 sends signals to Xinjie XC3-32R-EPLC12 sequentially within the preset time; on the one hand, the PLC sends a time start or stop signal to the pneumatic control module according to the signal transmitted by the touch screen, on the other hand Receive the pressure value fed back by the digital display pressure gauge and send a pressure switching signal to the p...

A multifunctional automatic box-adjusting device comprises a PLC control module, a pressure control module, a digital display pressure gauge, and a pneumatic control module, wherein the PLC control module is used for converting a pressure value fed back by the digital display pressure gauge into a pressure switching signal, and sending a time signal within preset time to control the pneumatic control module to act; the pressure control module is connected with high pressure gas, and adjusts working gas pressure for a pressurizing phase, a box-adjusting phase, and a strike-through phase according to LCDs of different models; the digital display pressure gauge is connected with an external box-adjusting tool, and is used for measuring the working gas pressure of the box-adjusting tool and feeding back the pressure value to the PLC control module so as to enable the PLC control module to generate a pressure signal to control the pneumatic control module to act; the pneumatic control module supplies working gas pressure to the box-adjusting tool under the action of the PLC control module. The multifunctional automatic box-adjusting device can accurately set pressure and time process parameters during the LCD box-adjusting process, solves the problem of as LCD box-adjusting time is not accurate or air pressure is not precise in the prior art, box adjusting is uneven, and improves the production efficiency.
Description
technical field [0001] The invention relates to automatic control technology, in particular to a multifunctional automatic box adjusting device. Background technique [0002] At present, TFT-LCD manufacturers are in the crystal filling stage of the LCD slit filling process. Due to the relatively low operating efficiency of the box adjustment device or the inaccurate control of the box adjustment pressure, it is easy to cause LCD module manufacturers to have medium light transmission in the display effect during production. The degree is not good, the center is purple, the box is taiko, and the frame is purple. When HTN and STN are attached to the positive display, it is easy to have bad phenomena such as yellowing in the middle and yellow borders, and it is easy to have bad phenomena such as whitening or blackening in the middle in the negative display mode, so the operation process at this stage must be strictly controlled during the box adjustment process Parameters, stri...
