Separating method of plasma display panel

Abstract

This invention relates to one plasma display panel isolation method, which is applied into one first and second baseboards by glue agent, which comprises the following steps: providing one rack to support the first baseboard end to make the second baseboard hang; then by use of match device to add second baseboard match weight; finally heating the plasma display panel into glue softening point; the glue achieves melt point to dissipate glue force to make the second baseboard separate with first one when the gravity of the second baseboard is larger than the remaining glue.

Description

technical field [0001] The present invention relates to a plasma display panel separation method, in particular to a method of increasing the counterweight of the second substrate by means of a counterweight device, so that the second substrate cooperates under the action of gravity to heat the adhesive to the softening point, and the second substrate is combined with the first substrate. A display panel separation method for substrate separation. Background technique [0002] Generally, in the plasma display panel production process, many defects of the front and rear substrates can only be found after the panel is assembled and lit. Generally speaking, most defective products found at this stage can only be detected by Substandard products are shipped, or when necessary, split analysis is performed on these defective products to analyze the causes of product defects during the manufacturing process, as a basis for improving the front-end production process. [0003] The p...

Problems solved by technology

[0003] The processing method of the above-mentioned defective products will increase the production cost. In addition, when using the traditional split method for analysis, if the area to be analyzed is located at the periphery of the panel and it is difficult to sample, it will often cause sampling failure. This will not only cause It reduces the waste of products, but also fails to achieve the purpose of split analysis

[0004] Known panel separation techniques used in plasma display panels generally use methods such as heating at the softening point, soaking in acids, direct cutting, adding metal guide grooves in the panel to heat and extend the crack source, etc. However, the above methods are often due to the use of Improper external forces and chemicals can cause damage to the panel or cause danger during operation and environmental protection issues. In addition, the panel separation method used is too complicated, so that the known panel separation method has many unsafe, unenvironmental protection and complicated operating procedures.
