1, the size of the glue
The size of the glue is determined by the duration of the glue, the longer the time. According to our experience, the bigger the glue. The size of the adhesive dot diameter shall be 1/2 of the product spacing. This will ensure that there is enough glue to bond the components and avoid the waste caused by too much glue.
2, point glue cost
The point glue scheme is varied. Not all points need to use the machine, and not all automated points must be attached to the point glue machine. In terms of cost, if a glue needs to be overpriced, consider replacing the glue. If the price of the automatic glue machine is too high, consider moving products instead of the glue head.
3, work efficiency and environmental impact
Products less, do not pursue efficiency, use manual glue machine; Outdoor work, rubber gun. Require accurate control of the amount of glue, use of machines, require automated glue, use machines with automated functions(more expensive and efficient).
4, glue properties
Ordinary glue uses a single set of glue machines, AB glue uses a double glue machine, PU glue uses a PU glue machine, and UV glue uses a specific syringe glue.
5, the composition of the glue
Commonly used glue: Epoxy resin, UV glue, silica gel, anaerobic glue, instant glue, etc.. If it is AB two-component glue, consider its proportion.
The viscosity of the glue is fluid
The less fluid the glue, the thicker it is, and the more complex the equipment.
7, AB glue glue machine in use pressure
The size of the pressure determines the amount of glue supplied and the speed at which the glue flows out. The worse the fluidity of the glue, the thicker it is. The greater the pressure it requires, the pressure should be selected according to the nature of the glue, the working environment temperature, and the size of the glue. The high ambient temperature will make the glue viscosity smaller and fluidity better. At this time, the pressure value needs to be lowered. Instead, increase the pressure(regulated by a pressure regulator).
8, needle size and type
The size of the needle will affect the size and accuracy of the gum. When the pressure is fixed, the larger the needle's nozzle, the larger the gum. The gum needle should be selected according to the product size. The general size of the needle should be the diameter of the glue point. About 1/2 of the diameter, It works best.
