  • Publication number: 20210116342
    Abstract: The invention discloses a mechanical performance testing device and a hydraulic control system thereof. The instrument comprises a base, a fixing means, a first testing means and a second testing means. Wherein the base is connected with the fixing means, each of the first testing means and the second testing means is configured to cause the fixing means to move in various directions. And the instrument can simultaneously apply multiple forces and torques on the element, such that the different stiffness characteristics of the element can be tested simultaneously. The hydraulic control system comprises fuel tank, oil pump and control valves. And the fuel tank, the oil pump and the control valves connect successively. The mechanical performance testing device with hydraulic control system can improve efficiency of the test, reduce the working intensity of inspector, increase the security in detection process, and improve the accuracy of measurement results.

  • Patent number: 8970245
    Abstract: A probing device for a TFT-LCD substrate, which includes a device body, a device body, a circuit board mounted on the device body, a plurality of motors mounted on the device body, and a plurality of probe pins respectively mounted to the motors. The motors and the probe pins are arranged in a one-to-one corresponding manner. The circuit board includes a programmable logic controller and a man-machine interface terminal electrically connected to the programmable logic controller. The plurality of motors and the plurality of probe pins are electrically connected to the programmable logic controller. The plurality of probe pins is set at locations corresponding to locations of panel inspection signal input pads of TFT substrates of various sizes. The programmable logic controller uses the motors to control the elevation and lowering of the probe pins.

  • Publication number: 20140132866
    Abstract: The present disclosure provides a liquid crystal panel, a manufacturing method thereof and a manufacturing method of a CF substrate. The manufacturing method of the liquid crystal panel includes: manufacturing a CF substrate and a TFT substrate with voltage-applying terminals, forming through holes at positions of the CF substrate corresponding to the voltage-applying terminals of the TFT substrate, and bonding the TFT substrate and the CF substrate. With the through holes formed in the CF substrate and corresponding to the voltage-applying terminals of the TFT substrate, the voltage-applying terminals can be revealed without cutting the CF substrate after the CF substrate and the TFT substrate are bonded together, which avoids reprocess due to cutting abnormality and further improves the yield rate of the liquid crystal panel.
