Therefore, when choosing dispensing needle, the suitable dispensing needle should be selected according to the properties of glue, dispensing requirements, dispensing accuracy requirements and air pressure requirements. Although hand-held teaching box is used to set dispensing parameters of three-dimensional dispensing machine, dispensing accuracy is not affected, dispensing time can only be controlled. Conflict with air pressure can also lead to many dispensing problems, such as glue dropping from glue valve, glue leakage from glue valve, plugging of needle, etc. It needs to be operated and selected according to the working principle of three-dimensional dispensing.
