Desktop dispensing machine how to accurately control the glue and solve the glue bubble problem

Desktop dispensing machines are widely used in manufacturing companies. During the use of equipment, precise control of glue and solution of glue bubbles are needed to reduce the defective rate and increase production efficiency. This is not only excellent in use but also in dispensing machines. Under the circumstances, the glue used in combination with it is also very much related, because different dispensing processes are different for the ratio of mixing, the amount of glue, the viscosity, the fluidity, the operation time, the curing time, and the like. In order to successfully achieve the dispensing requirements, the quantification of glue is very important. How can dispensing equipment accurately control the glue and solve the glue bubble problem?

1. Optional dispensing control valve, the glue used in the mixing pipe section of the front of the mixing port to reduce the glue waste, but also conducive to the uniform mixing of the glue, the general configuration dynamic dual-liquid dispensing valve and dynamic mixing The glue is applied to the pipe, and the dynamic valve and the dynamic mixing pipe can be used to fully mix the glue under the click of the click, and the glue is fully mixed after the glue is mixed to meet the purpose of the glue filling process.

2. The longer the glue is dispensed, the longer the glue will be, and the smaller it will be. For non-quantitative requirements, the diameter of the dots is half the diameter of the product, which ensures sufficient glue to bond the components and avoid the waste of glue.

3. Familiar with the viscosity of the glue used, the higher the viscosity, the poorer the fluidity will be, and the pressure required for the visual dispensing machine will be relatively large. Silicone dispenser

4. If there are many bubbles in the glue, vacuum the glue and then use the dispenser to ensure the quality of the dispensed product. Bohai dispenser equipment

5. Control the use temperature of the glue, the general epoxy resin glue should be stored in the refrigerator 00c-50c, should be used half an hour before use, so that the glue fully with the use of working temperature in line with the ambient temperature of the viscosity of the glue The influence is very great, if the temperature is too low, the dots will become smaller and the wire drawing phenomenon will occur. At the same time, the temperature of the environment should also be guaranteed. The moisture content of the small gel dots can dry out and affect the adhesive force.

6. Adopt more sophisticated mechanical movement parts

According to the dispensing technology requirements, precision stepper motors can be equipped with rails or precision servo motors equipped with screw guides.
