LCD dismantling machine

Abstract

The invention discloses a liquid crystal display screen disassembling machine, which comprises a rack and a lifting platform, wherein a workbench and a plurality of blade assemblies which are located on the side of the workbench are arranged on the rack; a vibration device is arranged on the blade assemblies; each blade assembly comprises a substrate, a blade seat which is arranged on the substrate in a sliding way and at least one disassembling blade which is arranged on the blade seat; the vibration device is used for driving the blade seats to vibrate to and fro relative to the substrates; lifting sliding blocks are arranged on the substrates; the lifting platform is movably arranged on the rack and is pushed by a driving device to vertically move; the lifting platform is provided with a plurality of lifting sliding rails which are matched with the lifting sliding blocks; the lifting sliding rails form a slant angle with a horizontal plane; and each lifting sliding block is arranged on the corresponding lifting sliding rail in a sliding way. According to the liquid crystal display screen disassembling machine, a liquid crystal display screen can be uniformly stressed in every direction; and meanwhile, the disassembling blades can produce vibration, so that the liquid crystal display screen can be completely and efficiently disassembled, and the liquid crystal display screen can be prevented from being damaged.

Description

technical field [0001] A liquid crystal screen dismantling machine. Background technique [0002] In the production and assembly of LCD screens, a glass plate needs to be aligned and bonded to the front surface of the LCD module. During this process, the glass plate and the LCD module will inevitably be misaligned and produce defective products. Defective glass plates and liquid crystal components are detached and rebonded. At present, the dismantling of liquid crystal screens is usually carried out manually. Since the glass plates of existing liquid crystal screens are very thin, the glass plates are easily broken during manual dismantling. Scrap, and LCD screens, especially large-size LCD screens or touch LCD screens, have a relatively high glass plate price.

[0002] In the production and assembly of LCD screens, a glass plate needs to be aligned and bonded to the front surface of the LCD module. During this process, the glass plate and the LCD module will inevitably be misaligned and produce defective products. Defective glass plates and liquid crystal components are detached and rebonded. At present, the dismantling of liquid crystal screens is usually carried out manually. Since the glass plates of existing liquid crystal screens are very thin, the glass plates are easily broken during manual dismantling. Scrap, and the glass plate of the LCD screen, especially the large-size LCD screen or touch LCD screen, is expensive. If the scrap rate is too high, the production cost of the LCD screen will be greatly increased.

In addition, there are also a small number of manufacturers that use dismantling machines to disassemble LCD screens. These dismantling machines usually use motors to drive dismantling blades to insert into the gap between the glass plate and the LCD module to cut the adhesive glue. These dismantling machines are relatively Compared with the traditional manual dismantling method, the movement of the dismantling blade is relatively stable. However, when these dismantling machines are working, one end of the glass plate needs to be fixed first, and then the dismantling blade is inserted into the gap between the glass plate and the liquid crystal module. Dismantling, the dismantling blade will generate a large longitudinal bending force and lateral extrusion force on the glass plate, the glass plate is still prone to damage and fragmentation, and because the connection between the adhesive colloid and the liquid crystal module and the glass plate is relatively difficult Strong, the blade of the existing dismantling machine only moves and cuts along the working direction, which will generate a large lateral pressure on the colloid and the glass plate, which will easily cause the glass plate to be damaged due to excessive force
