Description

Technical Field

[0001] The invention relates to the technical field of optical fiber fusion splicing, and in particular to a ceramic mechanism for sticking optical fibers. Background Art

[0002] Pasting fiber optic ceramics is a very important step in the assembly process of the fiber optic fusion splicer. It requires that the up and down, front and back, and horizontal dimensions of the fiber optic ceramics are very precise. Otherwise, in subsequent tests, low fiber optic insertion rate and poor loss will occur. Unqualified ceramics need to be knocked off and re-pasted, which increases material costs and reduces assembly efficiency.

[0003] In the actual assembly process, before the ceramic is glued, the ceramic grooves on the two core-aligning frames must be kept in the center position of the entire core-aligning frame. Traditional operations are all done manually with the cooperation of tooling and fixtures to determine whether the ceramic grooves are in the center position. However, the tooling and fixtures have gaps due to assembly reasons, which leads to errors in the center position. The optical fiber ceramic itself is relatively small in size and is not easy to hold manually. In the actual operation process, the ceramic is often directly broken during the pasting process. Due to the uncertainty of manual glue application, some ceramics have more glue on the lower surface, while others have less glue. The excess glue will overflow from both sides of the ceramic, which is difficult to clean and affects the appearance. Less glue has less adhesion, and the ceramic will fall off over time, increasing the chance of the product being returned to the factory for repair. After the ceramic is glued, whether it is level still needs to be observed and adjusted by the naked eye. The completed assembly needs to be placed aside for 24 hours before it can be used. In the actual use process, there are still subsequent problems such as poor fiber insertion and loss due to poor ceramic adhesion, and the ceramic needs to be replaced to repeat the previous work, which reduces operating efficiency and increases costs.

[0004] It can be seen that the non-standard operation of manual optical fiber ceramic pasting restricts the assembly quality and efficiency of the optical fiber fusion splicer. Developing an automatic optical fiber ceramic pasting equipment to effectively improve the qualified rate of the finished products of pasted optical fiber ceramics, improve the work efficiency of optical fiber ceramic pasting, and reduce material costs has become a technical problem that needs to be solved urgently.

[0019] 3. Beneficial effects:

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] Compared with the traditional manual ceramic bonding process, the optical fiber ceramic bonding mechanism of the present invention has a certain tolerance between the ceramic position after bonding and the theoretical center position due to the manual operation that requires manual adjustment of the position of the core adjustment frame groove, and the horizontality of the ceramic cannot be ensured. The operation is cumbersome and inefficient. In the actual operation process, manual operation errors may cause the ceramic to break in the middle, thereby increasing the material cost. The optical fiber ceramic bonding mechanism provided by the present invention solves the above problems well, ensures the uniformity of the ceramic bonding process, and plays a huge role in improving operation efficiency and reducing material costs.

[0035] like Figure 1-7A fiber optic ceramic pasting mechanism comprises a base 1 and a rotary indexing platform 2 located on the base 1, on which an image recognition device 22, a glue coating device 23 and a ceramic grabbing device 24 are sequentially arranged along the circumferential direction, wherein a placement area for cooperating with each device is reserved at the workstation where the image recognition device 22, the glue coating device 23 and the ceramic grabbing device 24 are located, on which a core adjustment component 21 is placed, and the image recognition device 22 is used to identify whether a pair of core adjustment frame grooves 2131 in the core adjustment component 21 are in the center position, and glue is applied to the bottom of the core adjustment frame groove 2131 through the glue filling tube at the bottom of the glue coating device 23, and finally the ceramic grabbing device 24 grabs the ceramic workpiece and places it and presses it on the core adjustment frame groove 2131.

[0036] The core adjustment component 21 is fixed on the rotary indexing platform 2 by magnetic attraction and is positioned by a positioning pin. The core adjustment component 21 is first placed under the image recognition device 22. After the image recognition device 22 recognizes that a pair of core adjustment frames 213 in the core adjustment component 21 are in the center position, the rotary indexing platform 2 rotates 45°, and the core adjustment component 21 rotates to the bottom of the glue coating device 22. The lower end of the glue coating device 22 is provided with two glue filling tubes, which can apply glue to the bottom of the groove 2131 on the corresponding core adjustment frame 213.

The bottom of the ceramic cannot be cured immediately after being coated with glue, and it needs time to be placed. If it is in a normal temperature environment, the waiting time is long, which is not suitable for mass production, and the production efficiency will be greatly restricted. The present invention is provided with a heating and drying device 25 at the next station of the ceramic grabbing device 24.

[0046] The two core adjustment frame grooves 2131 originally have a misalignment of 1 mm. Through the image recognition device 22, the control module 29 controls the rotation of the core adjustment motor 214, so that the cam 215 on the inner side of the core adjustment motor shaft rotates, thereby pushing the core adjustment frame 213 to swing relatively and make it in the center position. It should be noted that the position of the core adjustment frame on the core adjustment assembly 21 is only adjusted by the control module 29 at the first station, and the core adjustment assembly 21 with the adjusted position will enter the second to eighth stations in turn to complete the above actions.
