Nowadays, there are more and more manufacturers using dispenser equipment for dispensing. Some manufacturers often encounter such situation when using automatic dispenser for dispensing: the effect of the same equipment in different manufacturers is completely different. This is because there are many factors in the process of dispensing, which will have more or less influence on the dispensing effect of the dispenser, so we need to know which factors will affect the dispensing effect of the dispenser, so that the dispenser can achieve a good state in the use process.
1、 The size and stability of dispensing pressure will affect the dispensing effect
It is necessary to find the appropriate air pressure through many experiments after determining the appropriate dispensing needle for substituting processing and contacting surface. If the air pressure is too high, it will cause glue overflow and too much glue; if the pressure is too low, it will cause intermittent glue feeding, poor glue mixing effect, and unstable air pressure will also cause uneven dispensing during dispensing. Therefore, the factory needs to maintain a stable and appropriate air pressure to ensure a good glue mixing effect when substituting for processing.

2、 The viscosity of the glue solution will affect the dispensing effect
High viscosity, slow glue, easy to pull; viscosity is too low, strong fluidity, glue control becomes difficult, easy to lose glue, so choose the appropriate viscosity glue is also an effective solution to solve the problem of glue efficiency in substitute processing.
The packaged glue should not have bubbles, otherwise it will cause part of the glue to break without glue during dispensing. Every time the rubber or hose is replaced, the air in the cavity should be removed first to ensure that the glue delivery will not be affected during dispensing.
3、 The proper distance between the tip of dispensing machine and the contact surface will also affect the effect of dispensing
Before each dispensing process, the distance between the dispensing needle and the working face should be calibrated, the dispensing effect under different parameters should be observed, the reasonable dispensing scheme should be summarized, the layout of the workshop should be adjusted appropriately, the operation and maintenance of machinery should be learned by special personnel, and special personnel should be responsible for the operation of dispensing machine equipment in the process of dispensing, so as to ensure that more than two people understand at the same time The operation of the machine can prevent one person from leaving the working position, and other personnel can immediately take over the machine to reduce the impact of personnel flow.
