Description

Liquid absorption component, liquid material receiving method and device

The invention relates to a liquid absorbing component, a liquid material receiving method and device, in particular to a liquid absorbing component, a liquid material receiving method and device suitable for misty liquid materials.

Dispensing machines are widely used in industry, such as semiconductor packaging, printed circuit boards, liquid crystal screen encapsulants, etc., for dripping, coating, and potting liquid materials on the surface or inside of each product at a precise location. Because the applicable liquid material is a viscous material, it is easy to leave glue residue on the needle tip during use, so it is necessary to clean the needle tip of the dispenser from time to time.

A conventional vacuum cleaning suction nozzle is used for cleaning a needle nozzle of a glue machine. The vacuum cleaning suction nozzle penetrates a sealing cover which is detachably covered on a main body with an inner cavity.
