Description

Automatic dispensing, curing and glue wiping mechanism for LED panel Technical Field The invention relates to the technical field of manufacturing equipment of liquid crystal display panels, in particular to an automatic dispensing, curing and wiping mechanism of an LED panel. Background In the process of manufacturing a liquid crystal display panel (LED panel), spot coating UV (ultraviolet curing) glue on the edge of a glass substrate is a key sealing process. The process aims to form a seal by curing glue, protect the internal circuit of the panel from being corroded by moisture and dust and ensure the long-term reliability of the product. The traditional post-treatment process of dispensing is generally as follows, after the dispensing equipment finishes the gluing at the appointed position of the glass substrate, the gap is filled by means of natural leveling and infiltration of the glue, and then the glass substrate is directly conveyed to a UV lamp curing furnace for irradiation curing. After curing, the glass surface is subjected to subsequent etching and other processes. However, with the rapid development of high-end application markets such as new energy sources and vehicle-mounted displays, more stringent requirements are put forward on the reliability and precision of the display panel. To meet these new standards, a key improvement is introduced in the manufacturing process, which requires the addition of a "rubbing" procedure after dispensing and after natural bleed-out and before final curing. The purpose of this procedure is to precisely remove the excess UV glue remaining on the glass surface due to capillary action, ensuring absolute cleanliness of the glass panel surface before curing. The method can effectively avoid the bulge or pollution formed after the residual glue is solidified, thereby obviously improving the yield of the subsequent etching process and the edge quality of the final product. Therefore, a mechanical mechanism with exquisite design and full automation is urgently needed, and the functions of glue wiping and curing can be integrated, so that the removal and the instant curing of the residual UV glue can be automatically, accurately and efficiently completed after glue dispensing, and the urgent requirements of the new-generation LED panel manufacturing process can be met.
