How to ensure the dispensing accuracy of the fully automatic visual positioning dispensing machine- Hongzhan Automation

The fully automatic visual positioning and dispensing machine equipment is widely used in various fields, such as semiconductors, electronic components, etc. Coincidentally, these categories have high requirements for the production process of fully automatic visual positioning dispensing machines. How can we ensure the dispensing accuracy of fully automatic visual positioning dispensing machines? Today we will talk about how to ensure the dispensing accuracy of the fully automatic visual positioning dispensing machine.

Settings for the amount of glue dispensed and the viscosity of the glue:

In general, the amount of glue dispensed should be half of the product distance, which ensures that the components have sufficient glue for bonding and there is no excess glue overflowing, making the automatic glue dispensing machine faster and more accurate. The adhesive viscosity is high and the adhesive point is small, presenting a simple phenomenon of wire drawing. The adhesive viscosity is low and the adhesive point is large, which may lead to the phenomenon of adhesive infiltration into the product. Therefore, it is important to select the appropriate adhesive viscosity for the automatic dispensing machine.

Setting of dispensing needle and dispensing pressure: The selection of the fully automatic visual positioning dispensing machine needle should be based on the product size and the diameter of the dispensing point. Generally, the size of the dispensing needle of the fully automatic visual positioning dispensing machine should be half of the size of the dispensing point. If the dispensing machine needle is too large, it can cause glue overflow and affect dispensing accuracy. However, if the dispensing pressure is too high, it will cause glue overflow, and if the pressure is too low, it may result in leakage or intermittent dispensing. Therefore, it cannot meet the required dispensing process for the product, resulting in low product qualification rate and low operating power.

Setting the distance between the dispensing machine needle and the working surface: Different fully active visual positioning dispensing machines also use different dispensing needles. Some needles have a certain degree of stop, while others do not. Therefore, it is important to grasp the dispensing distance between the needle and the working surface. Before each dispensing operation, it is necessary to calibrate the distance between the needle and the working surface.
