Jacking lighting test device for liquid crystal screen

Abstract

The invention discloses a jacking light test device for a liquid crystal screen. A transportation line with rollers in two rows is used for transporting a clamping fixture for fixing a liquid crystalscreen PCB connector; a probe base jacking drive mechanism is arranged below the inner side of the transportation line with rollers in two rows, a substrate in the mechanism is fixed with the rack andthen connected with a lifting frame via a lifting frame lifting drive device to control the lifting frame to move up and down, and a vertical guide structure matched with the substrate is arranged inthe lifting frame; a probe base fixing plate is fixed on the lifting frame, and a probe base is fixed on the plate; the lifting frame is also connected with a jacking positioning plate aligned and matched with the clamping fixture via an elastic mechanism, and the plate is an annular plate positioned around the probe base; and the rack is provided with a stopping rod used for stopping the clamping fixture above the probe base jacking drive mechanism. The device is higher in detection accuracy, high in detection speed and efficiency, suitable for production of factory assembly lines, and meanwhile is simple to control and relatively low in cost.

Description

technical field [0001] The invention relates to a liquid crystal screen lifting lighting test device. Background technique [0002] After the LCD screen is produced, it needs to be tested, and it is powered on to check whether it can light up the LCD screen. The core equipment of the test is the probe base, which is equipped with conductive contacts, corresponding to the conductive contacts on the LCD screen PCB board connector. The probe base is connected to the power supply through wires, when it is connected to the LCD screen After the PCB board connector is in contact, check the product quality by judging whether the LCD screen can be lit. [0003] In the traditional testing process in the industry, the probe base is manually operated to contact the product. The disadvantages are time-consuming and laborious, low efficiency, and manual alignment is difficult, the accuracy is poor, and it is easy to cause misjudgment due to operational errors. Therefore, there is curren...

AI Technical Summary

Problems solved by technology

[0005] 1) It is necessary to control the manipulator to complete the two directions of X-axis and Z-axis. There are many movements and high alignment requirements, which not only leads to slow speed and low efficiency, but also has a large detection accuracy problem;

[0006] 2) It is necessary to manually transfer the LCD screen PCB board connector that comes off the assembly line in advance, and then use the clamping fixture to fix it in place before performing inspection, which slows down the production speed and is not conducive to the factory's assembly line production operations;

[0007] 3) Multiple groups of control mechanisms in the X and Z directions are used for drive control, the control mechanism is cumbersome, and the equipment cost is high
