Today, with the development of science and technology, the application scope of dispensing system is becoming wider and wider, and industrial production has entered the era of automation. While the dispensing system is widely used, the rate of defective dispensing is increasing. What is the reason? Below, Guangzhou Ascend Precision Machinery Co.,Ltd. will analyze it for you:

1. Control of the amount of glue dispensed

The control of the dispensing amount of the dispensing system is very critical, which directly affects the quality of the dispensing machine. According to personal experience, the size of the dispensing amount cannot exceed half of the distance between the solder joints. You can follow this standard and decide according to the actual situation.

2. Control of dispensing pressure

The size of the pressure directly affects the amount of glue supplied and the speed of the glue flowing out. When the pressure of the dispensing system is large, the amount of glue is large, and the pressure of the dispensing system is small, and the amount of glue is small. We should make adjustments according to the specific dispenser characteristics, indoor temperature, and dispensing environment. The pressure of the dispensing system is adjusted through its internal pressure regulating valve.

3. Selection of dispensing system needles

The selection of the dispensing system needle is also an important factor affecting the dispensing quality of the dispensing machine. Guangzhou Ascend Precision Machinery Co., Ltd. reminds everyone that the diameter of the dispensing machine needle should be controlled as much as possible to about half the diameter of the dispensing volume.

4. Adjustment of glue temperature

Generally speaking, the storage environment of epoxy resin glue should be about 0~5 degrees Celsius, and the use temperature is about 23 degrees Celsius. It should be taken out from the storage room about half an hour before use, so that the glue can better adapt to the surrounding temperature. , to avoid the phenomenon of drawing the glue during use.

In the process of using the glue dispensing system, it is necessary to set the temperature for curing according to the curing time of the glue, so that the glue has sufficient strength and hardness after curing. At the same time, it is also equipped with a heat dissipation system and a constant temperature system to ensure the service life of the machine.

5. Control of glue viscosity

The higher the viscosity of the glue, the smaller the glue point, and even the phenomenon of wire drawing; if the viscosity is too low, the formed glue point will expand and even dye the pad, so it is very important to control the viscosity of the glue, we are at the point of use Use caution when gluing the system.

6. glue can not have air intervention

The glue must not be intervened by air. If there is air, there may be a phenomenon of emptying, which will seriously affect the actual dispensing effect. .Bubble will affect the product quality during the dispensing process for the dispensing system.

The dispensing system is composed of two parts, software and hardware. Although the automation technology of the dispensing system is very advanced, it is not human after all and cannot be satisfied with all aspects. Therefore, we must fully consider these 6 factors when using the dispensing system for dispensing, which will greatly improve the product quality and greatly improve the production efficiency of the enterprise.
