Why does the glue dispensing machine have unstable glue volume? How to solve the problem of unstable dispensing in automatic dispensing machines?

If the dispensing machine has unstable dispensing, there may be three problems, and the specific reasons need to be investigated one by one according to the usage situation. Now let's take a look at what possible problems may occur:

1. Unstable air pressure

Possible impacts: Poor dispensing accuracy and stability, prone to errors or leaks;

2. Unstable glue

Possible impacts: This problem generally occurs when the viscosity of the glue is high, and due to the high viscosity, the fluidity of the glue is poor, resulting in wire drawing or blockage of the glue outlet;

3. Unstable glue output

Possible impact: The amount of glue that needs to be dispensed may be too large or too small, making it difficult to achieve uniformity.

If you encounter the above problems, you can adjust the air pressure, reset the pressure value, and control the air pressure within an appropriate range. High and low air pressure should not occur;

Delay the next dispensing action; Add auxiliary equipment with vacuum suction function to ensure consistency of dispensing.

Here is a recommended TECHCON glue dispenser - TS350- with pinhole suction function and the ability to accurately and consistently apply low, medium, and high viscosity liquids

The TS350 series dispensing machine/controller is equipped with a large LCD that displays digital timers, pressure, and vacuum readings. The firmware provides up to 10 variable, sequential, or single action options for programming

The options. It is intuitive and easy to use, capable of precise and consistent gluingLow, medium, and high viscosityFluid.

The TS350/355 series includes vacuum driven“Suck back”Used to control material "tailing" and waste, and to control fluid dripping between dispensing cycles. These systems have user programmable features

Manual (blowing) and automatic dispensing cycle settings (program and time), and provide a "teaching mode" to determine the dispensing time required when the dispensing output is unknown.

Standard equipment includes a universal power supply, foot switch, air hose, sample tip, syringe barrel, and adapter that can be used at any time. Small footprint and light weight. Provide two versions of working pressure: 0 to 100 psi (0-6.9 bar) version suitable for general applications

The 0 to 15 psi (0-1.0 bar) version is suitable for specific low viscosity applications.
