Precision dispensing machine is a type of dispensing equipment with high precision.

The industries where precision dispensing machines are applied are generally high demand industries such as electronic communication, automotive manufacturing, mobile phone boards, mobile phone button dispensing, speaker dispensing, etc. The dispensing stroke range is small and the dispensing volume is small, requiring high-precision control. The sliding rails of the equipment and the transmission operation of the robotic arm have great flexibility compared to general dispensing machines. The glue is pressed out by air pressure and controlled by a valve for high dispensing accuracy. Today, the editor will explain to you how to control the dispensing volume of precision dispensing machines? Let's take a look together:

The inconsistency and amount of adhesive produced by precision dispensing machines depend on several factors, including adhesive viscosity, pressure, supply time, and instantaneous adhesive breakage performance. Among the four factors, the viscosity of the adhesive varies depending on the adhesive material. The viscosity values of commonly used adhesives are between 1000 and 100000 units. Under the condition of fixed viscosity, the higher the pressure, the higher the rate of glue dispensing; The viscosity and pressure are fixed, and the longer the glue supply time, the greater the glue output; The better the instant breaking performance of the adhesive, the less delay in dispensing and less dripping during wire drawing. In order to achieve precise control of the dispensing volume, the dispensing equipment must achieve accurate pressure regulation, accurate timing, and good adhesive breaking performance.

It mainly depends on your requirements for the product, such as high precision of plus or minus 0.002ml or higher, and using air pressure control, which can still be a bit difficult. And the pressure control is not as precise as mechanical methods for issues such as glue drawing and dripping. The control of the dispensing volume of the dispensing machine is mainly achieved through two ways.

1. The dispensing pressure can be controlled by adjusting the pressure regulating valve. As long as the pressure of the factory's gas source is stable, the dispensing pressure will be stable.

2. Another method to control the amount of glue is to control the glue dispensing time. The longer the glue dispensing time is set, the greater the amount of glue dispensed.

Glue dispensing machines, also known as coating machines, dispensing machines, dispensing machines, filling machines, etc., are specialized in controlling fluids. And the automated machine that drips and coats the fluid onto the surface or inside of the product can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no wire drawing, no glue leakage, and no glue dripping. Glue dispensing machines are mainly used for precise point, injection, coating, and dripping of glue, paint, and other liquids in the product process to the precise position of each product. They can be used to achieve marking, line drawing, circular or arc shapes.
