How to debug the coating machine to the best running state?

The best working state of the three proofing coating machine can be debugged from the aspects of needle selection, glue outlet time and dispensing pressure of the three proofing paint coating machine.

1. Selection of applicator needle:

The diameter inside the applicator needle should be the same as the glue spot radius. In the dispensing work, the appropriate dispensing needle can be selected according to the product size, and the appropriate needle should be selected for products of different sizes. In this way, the three anti glue coating machine can be used for dispensing to avoid the problem of defective glue spots.

The minimum dispensing amount of the coating machine is 0.005 ml less than the standard amount, the minimum inner diameter of the stainless steel needle is 0.1 mm, and the minimum inner diameter of the needle is 0.1 mm. The coating machine has a special needle, and the inner diameter can reach 0.02 mm.

Note: the height from the dispensing needle to the circuit board and the inner diameter of the needle are the most important parameters, so it is important to select the appropriate dispensing needle.

2. Setting of glue delivery time of applicator:

The dispensing amount should be set at half of the product spacing to ensure that there is enough dispensing amount to paste the components, and pay attention to excessive glue leakage.

The glue output of the coating machine can be adjusted by the glue output time of the dispensing machine. In actual production, the glue output and time can be set according to the specific conditions (workshop temperature, glue viscosity, dispensing speed, etc.).

3. Pressure setting of coating machine:

The amount of glue output of the coating machine is provided by the three proof glue coating machine controller to the rubber hose and needle. The pressure of the three proof paint coating machine determines the glue output and dispensing speed.

If the pressure is too strong, it is easy to spray glue, too much glue and other problems, which will affect the appearance and beauty of the product; If the pressure is too weak, uneven dispensing and leakage will occur, which will affect the product quality.

In actual production, the pressure should be set according to the specific environment, such as glue viscosity, environment of the production workshop, temperature and other factors.
