What are the methods to ensure the dispensing accuracy of the automatic dispensing machine?

First, the setting of the dispensing system

Automatic packaging equipment on the market is mainly based on contact dispensing. Therefore, the error of the dispensing product and the fixture has a slightly greater impact on the dispensing accuracy. When the error between the dispensing product and the fixture is too large, it will seriously affect the dispensing accuracy and cannot guarantee the quality of the dispensing product. In actual operation, the error can be reduced by adjusting the range area of the dispensing product and maintaining the stability of the fixture. Therefore, the dispensing operation usually sets a reasonable fixture according to the product itself.

2. Setting of dispensing needle and dispensing pressure

The needle of the automatic dispensing machine should be selected according to the size of the product and the diameter of the glue point. Generally, the size of the glue needle should be half of the glue point size. If the needle is too large, the glue will overflow and affect the dispensing accuracy. Excessive dispensing pressure will also cause the glue to overflow, and if the pressure is too small, it will leak or break the glue, and the glue process will not meet the product requirements, making the product inefficient.

3. The interval setting between the needle of the dispensing machine and the working surface

Different automatic dispensing machines use different needles. Some needles have a certain stop point, and some needles have no stop point. Therefore, it is very important to grasp the dispensing interval between the needle and the working surface. To calibrate the gap between the needle and the work surface.

4. Setting of the dispensing system

In general, the size of the glue should be half the distance between the products. This ensures that there is enough glue to bond the components and no excess glue spills out, making the dispenser faster and more accurate. The viscosity of the glue is large, the glue point is small, and it is easy to appear wire drawing. The viscosity of the glue is small, the glue point is large, and the situation of glue penetration and dyeing products may occur. Therefore, it is very important to choose the appropriate glue viscosity for the automatic glue dispenser. of.
