De hecho, el diámetro interior de la aguja del dispensador de pegamento debe ser la mitad del diámetro del punto de dispensación. La máquina automática de encolado tiene un alto contenido técnico, ¡pero el costo es alto!

La viscosidad y la viscosidad del pegamento afectan directamente a lapegamento quality of the pegamento dispenser.

 

Distribución manual, la máquina atornilladora automática adopta el principio de distribuidor manual para distribuir productos electrónicos, el proceso es simple, el costo es bajo y la desventaja es el desperdicio de mano de obra.

 

The principle of the automatic dispenser is to push out the pegamento with air pressure within a set time.

 

Just choose the appropriate syringe according to the air pressure, time, and you can easily change the volume of each injection. This can ensure the quality of pegamento dots and improve production efficiency. When the viscosity is high, the pegamento spots can be reduced, and even wire drawing can be performed. If the viscosity is small, the pegamento spots can be increased and the pads can leak. The time of each infusion is controlled by the instrument to ensure that the amount of each infusion is the same. When distributing, you should choose the dispensing needle according to the size of the gasket on the PCB. Choose the same needle but different phase difference gaskets should choose different dispensing needles.
