Nowadays, there are more and more electronic products that need dispensing, and the more strict the dispensing process, how can we improve the efficiency while improving the quality? The answer is, of course, the automatic dispenser. We all know that traditional dispensing is manually operated by hand. The work is not only complicated and large, but the use of the automatic dispenser not only frees hands, but also has great efficiency and quality. Appreciable effect! However, there are many problems in the production of automatic dispensers, and drawing is a common type. How can we solve the phenomenon of drawing?
For some low-viscosity glues, they are mostly applied to a large area of application, so the operation is relatively easy, and for some high-viscosity glues, they are difficult to spit out and the fluidity is very weak, so brushing often occurs. How to solve this phenomenon that affects the quality and aesthetics of dispensing? The following is explained by the automatic dispenser manufacturer:
1. Delay of closing glue
After closing the glue head, there will still be a little glue between the glue outlet and the valve. If you move immediately after closing the glue head, it may form a tail of glue, so we can use the delay of closing the glue. Way to avoid.
2. Pull up diagonally
Because the glue is viscous, the wire drawing action directly after closing the glue often fails to achieve the effect of breaking the wire, or the shape of the drawn wire does not meet the requirements. Therefore, after closing the plastic head, we perform a diagonal pull-up action to prepare for the short wire.
3. Heating glue
Heating glue can increase the fluidity of the glue, and can also solve the drawing in a certain sense, but it should be noted that the heating temperature should not be too high.
