Problems solved by technology

After the artificial flame baking is completed, the LCD panel is transported to the dispensing position for the step of dispensing photosensitive adhesive. At this time, the heat from the flame baking has been dissipated, and the dispensing effect of the LCD panel at room temperature is not ideal.

Abstract

The embodiment of the invention provides a glue dispensing device and relates to the field of liquid crystal display panel production. According to the glue dispensing device, the position, corresponding to a seal agent, of a liquid crystal display panel on an object stage, is heated by a heater, so that water vapor accumulating on the inner periphery of an exhaust hole is removed; then, photosensitive glue is dispensed by a coating pressure head at the involution interface of the seal agent, and the temperature of the involution interface of the seal agent becomes relatively high due to waste heat generated after the liquid crystal display panel is heated by the heater, so that the coating pressure head is coated with the photosensitive glue, and the infiltration capacity of the infiltration capacity at relatively high temperature is improved; a transmission mechanism is arranged on the object stage or a glue dispensing assembly, and the object stage or the glue dispensing assembly moves in the transmission direction under the action of the transmission mechanism, so that after one position is heated by the heater, the coating pressure head moves to the position for glue dispensing and the heater moves to the next position for heating; and accordingly, through such continuous operation, the working efficiency of the glue dispensing device can be improved when the glue dispensing effect is guaranteed.

Description

technical field [0001] The invention relates to the field of manufacture of liquid crystal panels, in particular to a glue dispensing device. Background technique [0002] With the gradual maturity of the development of liquid crystal display devices, the market has higher and higher requirements for thinning of liquid crystal display devices. To reduce the thickness of liquid crystal display devices, it is necessary to reduce the thickness of the glass substrate used for preparing liquid crystal displays. [0003] The thickness of the glass substrate is usually thinned by chemical etching thinning method, that is, a solution with hydrofluoric acid as the main solvent is used to chemically react with the surface material of the glass substrate, and the surface of the substrate is etched to make the substrate thinner. Since the thinning process is usually carried out after the liquid crystal panel has been formed and cut, in order to prevent the corrosive solution from enteri...
