Visual automatic glue dispensing valve is specially selected, mainly responsible for the processing of the glue dispensing work in the implementation, will automatically block the glue dispensing valve continues to flow when the viscosity of the glue is not suitable for dispensing work, the normal work of the visual nature of the system will automatically detect the glue dispensing valve, if there is a problem need to can react immediately and modify the execution of the process, long-term work is easy to make the dispensing valve response sensitivity decreased, so consumers should pay attention to stop dispensing the normal working condition adjustment and maintenance of dispensing valve. To maintain the stability of the dispensing work environment is an important factor to improve the quality of dispensing, visual automatic dispensing machine of the electronic product dispensing can not let external factors affect the dispensing quality if the working conditions, there is too much dust and foreign matter easily affect the dispensing object surface cleanliness, resulting in poor product docking effect, bad product is produced. So in the dispensing prior to ensure the environment clean and tidy.
