Western dispensing introduce advanced technology in China has been used in the military field, dispensing technology once needed in military bullets in the production line of production support, some practical high school was needed after the completion of the bullet seal between the cartridge and the dispensing primer, this is to ensure that the bullet will not in the process of storing damp metamorphism affect the normal use. With the needs of industrial production increased gradually, LED dispensing system has been widely used in industrial production, science and technology can be applied to the chip used in the production process, the first chip production demand is low so once the use of manual dispensing and manual dispensing mode gradually in the course of time to keep up with the further demand and backward, and long-term disadvantages of manual dispensing the exposed problem is more and more obvious, such as heterogeneity, the cost of dispensing too wasteful are important factors affecting the chip manufacturers profit, and dispensing directly to the manufacturer to solve these problems, LED can keep the consistency of the dispenser dispensing chip in the implementation of work, and that there would be no human bias because of the long-term work and, and the dispensing package has better effect, higher protective effect.
