Liquid crystal substrate glass splitting device

Abstract

The invention relates to the technical field of mechanical equipment, and discloses a liquid crystal substrate glass splitting device which comprises a table plate and a breaking tool bit. Two scrap removing transverse grooves which are symmetrically distributed are formed in the middle of the table plate. A single supporting platform is arranged; each glass monomer on the substrate glass is independently supported and fixed; when the breaking tool bit is used for breaking the substrate glass, the downward pressing of the breaking tool bit can be followed, the substrate glass on two sides of the notch can rotate for a certain angle, the pressure on the substrate glass on the two sides of the notch when the breaking tool bit is pressed down is reduced, the damage rate caused by compressionis reduced, the instantaneous friction force between the substrate glass and the single supporting platform is reduced, and the wear of the contact surface between the two is reduced; and meanwhile, through the arrangement of connecting holes and an electromagnetic connecting device, every two single supporting platforms are connected, so that during overturning, the action consistency of the single supporting platforms and the surface smoothness of the single supporting platforms are guaranteed, and the safety of the substrate glass is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a liquid crystal substrate glass splitting device. Background technique [0002] In the manufacture of liquid crystal displays, in order to improve production efficiency, reduce manufacturing costs, and form large-scale mass production, multiple liquid crystal displays are often produced on a larger glass, and there are multiple groups of liquid crystals on the glass after silk screen printing. For the unit of the display, these small units must be divided to perform liquid crystal perfusion, and the cutting process is to split the whole box of glass into a monomer of the liquid crystal display. The cutting process is divided into two processes: cutting and splitting. The cutter wheel forms a slit with a certain depth and width on the glass, and then splits the cut glass with a splitter. The principle of the splitter is as attached Figure 6 As shown, the substrate g...

Problems solved by technology

[0003] as attached Figure 7 As shown, when the fracture cutter head 8 exerts pressure on the substrate glass 4 to split, the middle part of the substrate glass 4 is stressed. Due to the existence of the cut, the bottom of the cut opens to both sides during the process of the fracture cutter head 8 pressing down, and The glass monomers on both sides of the incision are turned upwards, and the glass falls down after breaking, which may cause damage to the glass monomers. At the same time, during the turning process, the monomers at the incision are squeezed and produce huge friction with the upper surface of the platen 2, which is easy Cause the single body to wear, even break, and cause wear to the surface of the platen 2

[0004] When the substrate glass 4 splits into a single body, some debris will be produced at the fracture site, which will fall on the platen 2, and the debris cannot be cleaned in time during the fracture process. On the one hand, it is necessary to wait until the glass monomer is removed before cleaning The debris on the platen 2 is cleaned, and on the other hand, the debris is easy to adhere to the substrate glass 4, which has a great impact on the subsequent process, resulting in a decrease in the production efficiency of the liquid crystal display.
