For example, when a liquid crystal display panel is manufactured, liquid crystal is filled between upper and lower substrates, and frame glue is applied to the edges of the substrates in order to seal the liquid crystal between the upper and lower substrates. Because the machine stability of the glue coating mechanism and the possible situations of glue overflow, blockage, bubbles and the like exist at the glue outlet head, in order to ensure the sealing performance between the upper substrate and the lower substrate, the coated glue needs to be uniform and qualified in size, and therefore the substrate after being coated with the glue needs to be placed on a detection table to detect whether the size of the glue is qualified or not. The detection table in the prior art only corresponds to the base plate of one specification, the base plates of different specifications need to be replaced by different detection tables, and the detection table is low in universality, so that the detection efficiency is low.
