How to debug the automatic glue dispenser to achieve the best running state

1. The setting of the glue dispensing time of the glue dispenser The amount of glue should be half of the product spacing, so that there can be enough glue to stick the components and avoid excessive glue seepage. The amount of glue dispensed by the automatic dispensing machine can be controlled by adjusting the dispensing time. In actual production work, the dispensing setting can be set according to the environmental conditions (workshop temperature, glue viscosity, dispensing speed, etc.). time.

2. The pressure of the glue dispenser sets the amount of glue dispensed by the automatic dispenser controller to provide pressure to the hose and needle. The pressure determines the amount of glue dispensed and the speed of glue dispensing. Strong pressure can easily cause glue to spray out. , Too much glue will affect the appearance of the product; if the pressure is weak, there will be uneven dispensing and leakage points, which will affect the quality of the product. In actual production, the pressure should be set according to the viscosity of the glue, the environment of the production workshop, and the temperature. If the temperature is too low, the viscosity of the glue will increase and the fluidity will become worse. At this time, the pressure value needs to be increased, and vice versa.

3. The size of the needle of the dispensing machine In actual production, the diameter of the inside of the needle should be the same as the radius of the glue point. During the dispensing work, the dispensing needle can be selected according to the size of the product, and suitable needles should be selected for products of different sizes. It is beneficial for the automatic dispensing machine to perform the dispensing operation without the problem of glue point, and the height of the dispensing needle to the circuit board and the inner diameter of the needle are the most important parameters.

The minimum dispensing volume of the automatic dispensing machine is less than 0.005 ml, and the minimum inner diameter of the stainless steel needle is 0.1 mm. The minimum inner diameter of the needle is 0.1 mm. The special needle inner diameter of the automatic dispensing machine can reach 0.02 mm.
