Therefore, the instability of automatic dispensing is one of the most common reasons for dispensing glue in the production of plastics. The main manifestations are the inconsistent size of glue, drawing and tailing. There are many factors causing the instability of the dispensing shape. Among them, the inaccuracy of the dispensing time control and the instability of the equipment platform, the inappropriate size of the dispensing needle, the unstable fluctuation of the gas source, and the incomplete recovery of the dispensing valve The most common factor.

Automatic Dispensing Machines and dispensing machines are increasingly used in the bonding of semiconductor lighting products. The problem of dispensing fluorescent powder is also increasing. Phosphor precipitation causes the color temperature value of dispensing products. Inconsistent, the packaging effect will also be affected, so in the process of packaging the LED, you need to pay special attention to phosphor precipitation.

In the automatic dispensing process, the proportion of the glue is often more than one, and therefore the glue amount needs to be repeatedly and repeatedly proportioned according to the different requirements of the dispensing. The problem with multiple ratios is that the quality of the glue is abnormal and the dispensing is uneven. For more information please visit jinyu machine dispenser website: www.jinyumachinery.com
