Product dispensing process defects are: the size of the glue spot is not qualified, drawing, glue dip dyeing, curing strength is not easy to fall off and so on. To solve these problems, we should know that the dispenser in the dispensing quality affected by those factors, the following summarizes seven points, together to understand it.1. Size of dispensing amountAccording to the working experience, the size of glue spot diameter should be half of the product spacing. This will ensure that there is enough glue to bond the components and avoid excessive glue. The amount of dispensing depends on the time. In practice, the dispensing time should be selected according to the production conditions (room temperature, glue viscosity, etc.).2. Dispensing pressureThe dispensing equipment provides a certain pressure to the syringe (glue gun) to ensure the glue supply. The pressure determines the glue supply amount and the glue outflow speed. If the pressure is too high, the glue will overflow and the glue quantity will be too much; if the pressure is too small, the intermittent phenomenon and leakage will appear, which will lead to product defects.3. Needle sizeIn practice, the inner diam...
