Technical Field

The invention relates to the field of glue dispensing, in particular to an online glue dispensing device.

Background

Dispensing is a process, also called glue applying, glue spreading, glue pouring, glue dripping and the like, and is to apply, fill and seal and drip electronic watering, oil or other liquid on a product, so that the product has the functions of pasting, filling and sealing, insulation, fixation, surface smoothness and the like.

The existing glue dispensing method comprises the following steps: 1. the manual dispensing is carried out, and the manual dispenser is manually used for dispensing on the electronic product, so that the process method is simple, but the manual cost is high and the efficiency is low; 2. the automatic dispensing is realized by pushing out the glue solution within a set time by using air pressure, and controlling the time of each drop injection by using an instrument to ensure that the drop injection amount is the same. The method can easily change the amount of each injection as long as the air pressure and time are adjusted and a proper needle nozzle is selected, which can improve the production efficiency, but in the existing automatic dispensing equipment, the product needs to be moved to a fixed position by a carrier, and the product continues to move after the dispensing equipment finishes dispensing, which does not realize continuous operation and increases the use cost of the carrier.
