[0030] Please combine Figure 1Now, the automatic cutting MPO connector multi-core optical fiber device provided by the utility model is described.
[0031] The automatic cutting MPO connector multi-core optical fiber device includes a frame 1, a power component 2, a cutting component 3 and a fixing component 4. The power component 2 is installed on the frame 1, the cutting component 3 is slidably connected to the frame 1, and the fixing component 4 is provided with a fixing port 41. The fixing port 41 is used for inserting the ferrule to expose the excess optical fiber of the ferrule outside the fixing component 4. The power component 2 can drive the cutting component 3 to move so as to cut the excess optical fiber of the ferrule through the cutting component 3.
[0032] It can be understood that the power component 2 of the automatic cutting MPO connector multi-core optical fiber device is installed on the frame 1, the cutting component 3 is slidably connected to the frame 1, and the fixing part 4 is provided with a fixing port 41, and the fixing port 41 is used to insert the core to expose the excess optical fiber of the core outside the fixing part 4. The power component 2 can drive the cutting component 3 to move to cut the excess optical fiber of the core through the cutting component 3, so that the end face of the optical fiber after cutting is consistent, the cutting efficiency is high, and it is not easy to cut the optical fiber in the connector into pieces, thereby avoiding product defects.
[0033] In this embodiment, the fixing member 4 includes a first side 42 and a second side 43 opposite to the first side 42. The ferrule is inserted into the fixing port 41 from the first side 42, and the excess optical fiber of the ferrule is exposed from the second side 43. Specifically, the second side 43 is a side close to the cutting assembly 3. After the ferrule is inserted into the fixing port 41 from the first side 42, the excess optical fiber of the ferrule is exposed from the second side 43, so that the cutting assembly 3 can cut the excess optical fiber of the ferrule.
[0034] Furthermore, the ferrule is interference-fitted with the fixing opening 41 , so that the ferrule can be stably installed in the fixing opening 41 .
[0035] In one embodiment, if Figure 1 As shown, the power assembly 2 includes a first mounting frame 21, a first drive motor 22 and a camshaft 23.

At this time, the second mounting frame 31 and the first mounting frame 21 pull the elastic member 34 to elastically deform, and then the first drive motor 22 drives the camshaft 23 to rotate eccentrically. Under the action of the elastic deformation of the elastic member 34, the second mounting frame 31 drives the roller 32 and the cutting module 33 to reset, so that the cutting module 33 can achieve reciprocating cutting.
[0038] Specifically, the cutting module 33 also includes a second drive motor 331 and a cutting blade 332. The second drive motor 331 is mounted on the second mounting frame 31. The output shaft of the second drive motor 331 is connected to the cutting blade 332 and is used to drive the cutting blade 332 to rotate. The second drive motor 331 can be a high-speed brushless motor. The second drive motor 331 drives the cutting blade 332 to rotate, so that the cutting blade 332 can cut the excess optical fiber.
[0039] In one embodiment, continue as Figure 1 As shown, roller 32 and camshaft 23 are on the same horizontal line. Like this, the force driven by camshaft 23 can act on roller 32 completely.
[0040] In one embodiment, continue as Figure 1 As shown, the automatic cutting MPO connector multi-core optical fiber device also includes a sliding structure 5, and the second mounting frame 31 is slidably connected to the frame 1 through the sliding structure 5. By setting the sliding structure 5, the second mounting frame 31 can be slidably connected to the frame 1, so that the second mounting frame 31 can move.
[0041] Specifically, the sliding structure 5 includes a sliding block 51 and a sliding rail 52. The sliding block 51 is mounted on the second mounting frame 31, and the sliding rail 52 is mounted on the frame 1. The sliding block 51 is slidably connected with the sliding rail 52. The second mounting frame 31 drives the sliding block 51 to move along the extension direction of the sliding rail 52, so that the second mounting frame 31 can move.
