[0024] The working principle of the glue coating device used for display screen substrate processing is described in detail below.

The deformation effect of the flexible compression and buffer stacked capsule 315 can weaken the vibration force of the external pressure on the substrate. When the arc shell 322 is squeezed by the upper display screen substrate, it will produce a certain deformation and cause a certain deformation of the conical contact plate 321. At this time, the central pressure-resistant cone column 324 abuts and supports the top of the arc shell 322 to prevent damage caused by excessive deformation due to compression. Combined with the divergent setting of the pressure dividing strip 325, it can enhance the dispersion effect of the pressure generated from above on the display screen substrate and evenly distribute the pressure from above.
