A method of injecting glue using an automated glue injection apparatus for an optical fiber connector as defined in claims 1-6, said material comprising a metal portion holding said ferrule, said metal portion comprising a through hole communicating with said ferrule bore, said ferrule further comprising a V-groove at one end thereof and in communication with said through hole, said method comprising the steps of:
s1, the manipulator grabs two materials from the vibration disc and places the two materials in two profiling holes of the clamp, the clamp moves to the position below the positioning plate along the conveying track, and the positioning plate descends to position the two materials;
s2, the first needle cylinder and the second needle cylinder descend until the first needle head and the second needle head respectively prop against the V-shaped grooves of the two materials, and the first needle cylinder and the second needle cylinder start to inject glue, wherein the glue injection time is T;
s3, the first needle cylinder and the second needle cylinder are lifted until the first needle head and the second needle head are lifted to the middle section of the metal part;
s4, stopping injecting glue from the first needle cylinder and the second needle cylinder, circularly carrying out the injection glue in a rising-suspending-rising mode along the Z-axis direction, and rapidly rising the first needle cylinder and the second needle cylinder along the Z-axis direction after the first needle head and the second needle head are extracted from the metal part, so as to finish the injection glue process;
s5, lifting the positioning plate to release the positioning of the two materials, and moving the clamp to the next station along the conveying track.
8. The method according to claim 7, wherein in the step S2, t=0.9-1.2S, the glue injection pressure of the first syringe and the second syringe is 0.5mpa, and the diameters of the first needle and the second needle are 0.55mm.
9. The method of automated glue injection for optical fiber connectors according to claim 8, wherein in step S3, the first syringe and the second syringe are raised by 3mm at a speed of 1.5 mm/S.
10. The method according to claim 9, wherein in the step S4, the first syringe and the second syringe are suspended for 1S to continue rising after rising at a speed of 2mm/S for 1mm, and the circulation is performed for 3 times.
