A liquid crystal substrate glass splitting device

Abstract

The invention relates to the technical field of mechanical equipment, and discloses a glass splitting device for a liquid crystal substrate, which includes a platen and a breaking cutter head, and two symmetrically distributed horizontal chip removal grooves are opened in the middle of the platen. Through the setting of the monomer support platform, each glass monomer on the substrate glass is individually supported and fixed, so that when the fracture cutter head splits the substrate glass, it can follow the downward pressure of the fracture cutter head, and the substrate glass on both sides of the cut can be Rotate at a certain angle to reduce the pressure on the substrate glass on both sides of the incision when the broken cutter head is pressed down, reduce the breakage rate caused by compression, and reduce the instantaneous friction between the substrate glass and the single support platform, reducing both The wear of the contact surface, at the same time, through the setting of the connecting hole and the electromagnetic connection device, the single support platform is connected in pairs, so that when turning over, the consistency of the movement of the single support platform and the flatness of the surface of the single support platform are improved. Safety of substrate glass.

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 Image 6 As shown, the substrate gl...

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.
