Is the adjustment of dispensing precision related to the dispensing needle?

Dispensing accuracy is very important for dispensing. If you don't understand dispensing accuracy, you can't point out good accuracy. In fact, dispensing accuracy is related to Dispensing nozzle  and core accessories, such as Dispensing nozzle guide rail and controller. These three accessories control Dispensing nozzle accuracy. Needle inner diameter, guide rail precision and controller air pressure stability.

1. Dispensing nozzle needle: This is the core of controlling the Dispensing nozzle accuracy. If the dispensing accuracy is 0.05mm, the inner diameter Zui of the dispensing needle used is better than the inner diameter of 0.05mm, and the glue flow can meet the demand. The automatic machine can use a smaller needle, and a smaller needle can also meet the dispensing accuracy. The dispensing accuracy can be adjusted according to the inner diameter of the needle.

2. Guide rail: there are linear guide rail and screw guide rail. The accuracy difference between them lies in motor control. The linear guide rail adopts stepping motor, and the accuracy can reach 0.1mm, while the accuracy of servo motor can reach 0.01mm, with a difference of 100 times. The control accuracy of linear guide rail is relatively poor, which can not be remedied.
