Embodiment Construction

[0022] like figure 1 As shown, it is a schematic diagram of the structure of the LCD screen dismantling device of the present invention. This embodiment includes an upper machine table 1 and a lower machine table 2. The upper machine table 1 has an upper ventilation pipe 41, and the lower machine table 2 has a lower ventilation pipe 42; The upper suction cup 31 of the adsorption device is arranged on the upper ventilation pipe 41, and the lower suction cup 32 as the adsorption device is arranged on the lower ventilation pipe 42; 2 connected upper vacuum pump 61 and lower vacuum pump 62, and resistance wire 8 as a heating element.

[0023] In this embodiment, the upper machine table 1 and the lower machine table 2 are respectively provided with at least one suction cup. The upper suction cup 31 of the upper machine table 1 is used for suctioning the color filter substrate 11 of the liquid crystal display screen. The upper suction cup 31 is connected to the upper suction cup 31....

Abstract

The invention relates to a liquid crystal display screen splitter, comprising an upper board, a lower board, at least two absorption devices, a vacuum pump and a heating element; wherein the upper board and the lower board are provided with breathing pipes, the absorption devices are respectively arranged on the breathing pipes of the upper board and the lower board and used for fixing the liquid crystal display screen, the vaccum pump is connected with the absorption devices by the breathing pipes and used for vaccum suction on the absorption devices, and the heating element is arranged on the lower board and / or the upper board and used for heating glue for sealing the frame of the liquid crystal display screen. The invention has simple structure and low cost, and can efficiently split the liquid crystal display screen with less labor.

Description

technical field [0001] The invention relates to a device for disassembling a liquid crystal display screen, in particular to a liquid crystal display screen dismantling device. Background technique [0002] Failure analysis is an important link in the production process of Liquid Crystal Display (LCD). In the process of LCD research and development and production, there will be some defects and defects. The R&D personnel must disassemble the LCD, analyze the circuit in the defective area, find out the cause of the defect, and formulate an improvement plan. [0003] At present, when the failure analysis is carried out, the LCD is disassembled manually. When disassembling, first soften the frame sealant at the corner of the LCD screen with a fire source, and then use a metal sharp tool (such as a blade) or other tools (such as a business card) to insert the color filter substrate and the thin film transistor (Thin Film Transistor, referred to as TFT) substrate Then turn the ...
