The drawing has been plagued by the glue dispensing operation for a long time, mainly reflected in the drawing caused by uneven bonding and adhesive surface ugly, in the mobile phone dispensing link is the most taboo appearance, the reason is mainly produced drawing glue glue viscosity is too high, can solve the problem of high viscosity glue by heating, of course it can be solved by drawing the glue dispensing machine, if the dispensing pull back speed can play the effect of wire breaking instant glue, also there will be no glue drawing problem.
The glue point size also affect the mobile phone screen adhesion potential factors the most important link, because the glue point too much easy to make mobile phone screen glue overflow, leads to the appearance of very ugly, caused by the reasons for excessive glue glue is usually caused by excessive pressure, but also occupy a part of the needle selection factors, if the air compressor is not stable, may cause the air pressure is too large, the amount of glue extrusion is very much also, by adjusting the air compressor working condition can make the glue more stable, also won't have too big problem glue point.
