A switching spindle 35 is arranged, the switching spindle 35 is fixedly connected to the switching crossbeam 31, a first gear 36 is mounted on the switching spindle 35, a switching motor 37 is mounted on the lifting support 30, the output shaft of the switching motor 37 is connected to a second gear 38, the second gear 38 meshes with the first gear 36, the lifting support 30 is driven to move up and down by the extension and contraction of the cylinder 34, and the lifting support 30 drives the switching crossbeam 31 to move up and down. During crimping, the switching crossbeam 31 drives the crimping plate 11 to move downward, and the crimping operation is completed by squeezing the ferrule through the crimping plate 11. When the crimping is completed, After the ferrule tooling plate 9 is removed, it is necessary to perform quality inspection before cutting the optical connector.

[0033] Embodiment 3

[0034] Based on the second embodiment, Figures 1 to 3As shown, the conveying pipeline 7 includes an input pipeline 12, a conveying hose 13 and an output pipeline 14. The conveying hose 13 is arranged obliquely, and the high end of the conveying hose 13 is connected to the input pipeline 12. The input pipeline 12 is vertically arranged just below the output end of the tail handle vibration loading tray 2. The output pipeline 14 is vertically connected to the bottom end of the conveying hose 13. A conical guide tube 15 is fixed on the top of the input pipeline 12. The conical guide tube 15 is penetrated along its own axial direction and has a guide hole 16. The diameter of the guide hole 16 gradually decreases in the direction close to the conveying hose 13. The top of the conical guide tube 15 is The tail handle has a large accommodating space, so that the tail handle output by the tail handle vibration loading tray 2 can smoothly fall into the tapered guide tube 15, and under the action of the guide hole 16, the tail handle falls into the input pipe 12, and then enters the output pipe 14 through the conveying hose 13.

Similarly, the conveying pipe on the core insert vibration loading tray 3 has the same structure as the conveying pipe on the tail handle vibration loading tray 2, so accurate loading of the core insert is achieved.

[0035] Embodiment 4

[0036] Since it is necessary to sequentially load multiple tail handles into multiple tail handle tooling holes 6 and multiple ferrules into multiple ferrule through holes 10, in order to avoid sequentially conveying multiple tail handles or ferrules, based on the third embodiment, as shown in FIG. Figures 1 to 4As shown, the pipeline conveying assembly also includes a limit mounting frame 17, a front baffle 18 and a rear baffle 19. The rear baffle 19 is vertically arranged at the output end of the tail handle vibrating loading tray 2. The front baffle 18 is vertically arranged above the tail handle vibrating loading tray 2. The output end of the tail handle vibrating loading tray 2 is located between the front baffle 18 and the rear baffle 19. The front baffle 18 and the rear baffle 19 are staggered in the vertical direction. The front baffle 18 and the rear baffle 19 both have the freedom to move in the vertical direction. Two drive plates 20 are slidably arranged on the limit mounting frame 17. The opposite end surfaces of the two drive plates 20 are connected with racks 21. The two drive plates 20 are connected to the racks 21. A gear 22 is arranged between the racks 21, and the gear 22 is rotatably connected to the limit mounting frame 17 through the main shaft 23. The two racks 21 are meshed with the gear 22. A motor 24 is installed on the limit mounting frame 17, and the output shaft of the motor 24 is connected to the main shaft 23. The two driving plates 20 are respectively connected to the front baffle 18 and the rear baffle 19 through the special-shaped connecting rod 25. When the tail handle is not loading, the rear baffle 19 moves downward to block the output end of the tail handle vibration loading disc 2, so that the tail handle cannot enter the conveying pipe 7. At this time, the front baffle 18 is located between the end tail handle and the secondary tail handle, and is above the tail handle. When the tail handle is loaded, the motor 24 drives the main shaft 23 to rotate, the main shaft 23 drives the gear 22 to rotate, and the gear 22 drives the two racks 21 to move linearly. Since the two racks 21 are arranged opposite to each other, the movement directions of the two racks 21 are opposite. The two racks 21 respectively drive the front baffle 18 and the rear baffle 19 to move through the special-shaped connecting rod 25, so that the rear baffle 19 moves upward and separates from the tail handle, so that the front baffle 18 is inserted between the end tail handle and the secondary tail handle. The front baffle 18 is first inserted between the end tail handle and the secondary tail handle, and then the rear baffle 19 is separated from the end tail handle, and the secondary tail handle and the other parts are blocked by the front baffle 18. The tail handle at the rear is moved to the rear, and after the tail handle at the end loses the obstruction of the rear baffle 19, the conveying falls into the conveying pipe 7. Then, the motor 24 reverses, so that the rear baffle 19 continues to block the output end of the tail handle vibration loading tray 2, and the front baffle 18 moves upward to separate from the tail handle. At this time, the tail handle moves to contact the rear baffle 19 to complete the limit, and the tail handle in the previous position becomes the end tail handle. When the tail handle tooling plate 5 moves the next tail handle tooling hole 6 to the loading position, the rear baffle 19 and the front baffle 18 repeat the above actions, so that one tail handle can be accurately loaded each time. Similarly, the core vibrating loading tray 3 also loads one core at a time in this way.

A conical positioning hole 27 is provided, and a positioning cone 28 is fixed to the bottom surface of the core insert tooling plate 9. When the positioning cone 28 is adapted in the conical positioning hole 27, a plurality of core insert through holes 10 correspond coaxially to a plurality of tail handle tooling holes 6 one by one. When the robot arm places the core insert tooling plate 9 on the tail handle tooling plate 5, the positioning cone 28 is inserted into the conical positioning hole 27, thereby completing the positioning matching of the core insert tooling plate 9 and the tail handle tooling plate 5. At the same time, when the tail handle tooling plate 5 moves, the position between the tail handle tooling plate 5 and the core insert tooling plate 9 will not be offset.

[0039] The fully automatic fiber optic connector ceramic ferrule automatic crimping detection method, using the above-mentioned crimping detection device, comprises the following steps:
