Description
Technical Field
The invention relates to the field of automation equipment, in particular to a large-size panel pressure heating defoaming platform.
Background
In the field of flat panel display device production equipment, various optical film materials are often attached, such as polarizer attachment, after an optical film body is attached to a screen substrate, bubbles generated during attachment between the film body and the substrate need to be removed through various means, so that the attachment quality is ensured. The conventional bubble removing means includes various means, such as a method of improving the film material attachment, a method of using a side edge roller, and a method of rolling the film material while attaching to reduce the generation of bubbles. The mechanical defoaming method can achieve certain effect. However, for a large-sized panel, the effect of removing bubbles by rolling is poor due to a large area, and the panel is easily broken by rolling. Therefore, an auxiliary defoaming mode, such as a vacuum environment or a pressurization environment, needs to be adopted, the vacuum environment is to place the panel to be defoamed in a vacuum negative pressure environment, and the air pressure around the panel is reduced by adjusting to be smaller than the air pressure in the bubbles, so that the air in the bubbles is automatically extruded out from between the panel and the film material, and the defoaming effect is achieved; the panel is placed under the strong pressure environment in the opposite pressurizing environment, and the membrane body is extruded by external pressure to achieve the defoaming effect.
The defoaming time is longer and the pressure maintaining time is shorter after the defoaming time is deviated from the sticking time: 70-180S; pressure maintaining time after full pasting: 5-10Min, the efficiency of the traditional mode of placing all materials into the defoaming chamber and then defoaming has longer defoaming waiting time, the subsequent process can be carried out after the defoaming is completely finished, and the feeding and discharging before and after the defoaming also take longer time, thus leading to low overall defoaming efficiency. Therefore, for defoaming large-size panels, a defoaming mode of feeding single panels independently is generally adopted under the influence of the size of the panels; the device comprises a defoaming chamber, a feeding cavity, a defoaming cavity, a discharging cavity, a feeding cavity, a discharging cavity and a discharging cavity. The core technical problem related to independent defoaming is the formation of independent defoaming space, that is, in the whole defoaming machine, a plurality of independent defoaming spaces are included, each defoaming space independently completes vacuum or pressure defoaming action, the sealing of each independent defoaming space needs to be completed before vacuum or pressure defoaming is carried out, and the time consumed for forming the sealed defoaming space is a core factor influencing the independent defoaming efficiency; at present, the most common space sealing mode is to combine two half-cavity covers into a complete cavity body through external force action in a physical mode, and the sealing mode needs to be combined by driving a cover body through an external configuration driving mechanism; meanwhile, the physical contact combination of the two half cavity covers is influenced by material characteristics, so that all sealing surfaces can not be kept in a sealing state for a long time, and particularly, the sealing surface is larger for defoaming large-size panels with sizes of more than 65 inches, and the defect is more obvious.
