1. At the beginning, the size of the needle will affect the size and precision of the dispensing machine nozzle in the dispensing process. When the air pressure is at a certain boundary, the larger the needle mouth is, the greater the glue rate is, so the size of the glue needle should be determined according to the size of the product produced by the dispensing machine nozzle.

2. The isolation between the needle and the PCB board, the different dispensing machine nozzle uses the different needle, some needle has a certain degree of stop. Each thing should be done at the beginning of the needle and PCB isolation calibration, namely Z-axis height calibration.

3. The size of the dispensing amount is determined by the time of the dispensing machine nozzle in the dispensing process. The longer the time, the greater the amount of dispensing according to our body smell, the more Yunyun may guarantee that there is enough glue to glue the parts, and may avoid the resource wave caused by too much glue at the same time.

4. The size of the pressure directly affects the amount of glue and the rate of glue outflow, the worse the rolling of glue, the thicker it is, the greater the necessary pressure is, so we should treat the size of the pressure according to the temperature of the dispensing machine nozzle in the production process and the size of the dispensing amount and the characteristics of glue, The pressure of the dispensing machine nozzle is treated by the pressure regulating valve inside it.

5. For the curing of glue, the usual manufacturer has given the temperature arc. Usually at room temperature may be cured, in reality should be able to use a higher temperature to cure, so that the glue after curing enough strength and hardness.

6 bubbles treat dispensing machine nozzle in the dispensing process will affect the product, low product yield, so the glue put in before there are no bubbles. If there are bubbles, there will be many defective products produced by the nozzle of the dispensing machine. In use, the atmosphere of glue should be discharged to prevent the flash of the nozzle of the dispensing machine.

7. The vacuum suction valve must be assembled on the nozzle of the dispensing machine, because the vacuum suction effect may prevent the glue from dripping when the nozzle of the dispensing machine is not working. The assembly of this kit may reasonably treat the vacuum suction valve, thereby further limiting drip and wire drawing scenarios.
