Description

Technical Field

[0001] This invention belongs to the field of optical fiber processing and manufacturing, and in particular relates to an automatic fiber threading machine. Background Technology

[0002] In the field of optical fiber processing and manufacturing, the fiber threading process is a core and critical step in the production of optical fiber components. Its accuracy and efficiency directly determine the connection performance, transmission stability, and overall production capacity of optical fiber products. Currently, most fiber threading operations in the industry are still completed manually or with semi-automated equipment. This type of operation mode has exposed many technical defects and industry pain points in actual production, and it is difficult to meet the high requirements and high-efficiency production needs of modern precision manufacturing.

[0003] During manual fiber threading, operators must manually complete a series of operations, including glass slide gripping and positioning, fiber threading, adhesive dispensing, and curing assistance. This not only demands a high level of skill and concentration from the operators, but the subjectivity of manual operation can easily lead to positioning errors. The positional accuracy of fiber threading is difficult to control, and even micron-level operational errors can affect the transmission efficiency of the fiber, resulting in low product yield. At the same time, the pace of manual operation is slow, and the connection between each process depends on manual judgment and action switching. The production efficiency of a single workstation is low, making it difficult to adapt to the needs of large-scale production. Furthermore, the continuous investment in labor costs will increase the production and operation burden of enterprises.

[0004] While existing semi-automated fiber threading equipment can replace some manual operations, it generally suffers from low functional integration. Most can only complete simple needle threading or adhesive dispensing actions; processes such as slide transfer, positioning calibration, and adhesive curing still require manual assistance. The poor coordination between these processes prevents continuous operation throughout the entire process. Furthermore, the positioning systems of such equipment are rudimentary, lacking high-precision visual calibration and position detection mechanisms, resulting in insufficient positioning accuracy and difficulty in meeting the precision processing requirements of different fiber optic product specifications. In addition, some semi-automated equipment lacks professional anti-static protection structures, allowing static electricity generated during operation to cause irreversible damage to precision optical components such as slides and optical fibers, further reducing product quality. Simultaneously, the equipment has poor adaptability; most components are fixed structures, unable to be flexibly adjusted according to different slide and optical fiber product specifications, limiting its applicability and increasing the equipment investment costs for enterprises.

[0005] Furthermore, in traditional fiber threading operations, the adhesive dispensing process suffers from low precision control, leading to issues such as adhesive dripping and overflow. This not only wastes adhesive but also contaminates equipment and products. Additionally, the curing process often employs fixed-angle, fixed-intensity lighting, resulting in uneven adhesive curing and affecting the bonding stability between the optical fiber and the glass substrate. Moreover, both manual and semi-automated operations lack robust safety protection and position detection mechanisms, making them susceptible to equipment damage and personnel injury due to operational errors or over-range operation, posing significant production safety hazards.

[0006] In summary, the existing fiber threading process suffers from problems such as low efficiency, poor positioning accuracy, insufficient product consistency, poor process connection, lack of anti-static protection, and weak adaptability. These issues have become key factors restricting the fiber optic processing industry from developing towards high precision, automation, and large-scale production. Developing an automatic fiber threading machine that can automate the entire fiber threading process, has high positioning accuracy, strong adaptability, and is safe and reliable to operate has become an urgent need in the industry. Summary of the Invention

[0072] Working principle:

[0073] Initialization: Start the device, control the system to drive each component back to the origin, the first photoelectric sensor 305, the motion photoelectric sensor 2516, the second photoelectric sensor 407 and the photoelectric sensor 509 detect the position of each component to ensure that it is in the initial state;

[0074] Slide gripping and transfer: The anti-static gripping slide 310, together with the gripping suction component 313, grips the slide. The linear module 303 drives the viewing glass track 307 to move, transferring the slide to the slide moving platform 4 with the sensor slide support 413. The CCD vision component 316 and the area array camera 318 acquire images of the slide and calibrate the slide position.

[0075] Product positioning and threading: The product to be processed is placed in the threading positioning fixture 2407. The first positioning block 2409 and the second positioning block 2410 press the product firmly. The vision component 22 collects the product image and compares it with the position of the glass slide to calculate the deviation. The moving motor 2502 drives the ball screw 2506 to rotate, which drives the moving track plate 2507 to move, so that the threading component 24 is close to the glass slide moving platform 4. The multi-axis electric slide 2402 and the fine-tuning platform 2403 adjust the threading position according to the deviation to complete the fiber optic threading.

[0076] Dispensing operation: The first lead screw nut motor 2304 drives the first glue rail seat 2305 to move, and the second lead screw nut motor 2312 drives the second glue rail seat 2309 to move, positioning the dispensing component 2313 to the needle insertion position. The dispensing component 2313 outputs glue, and the glue tray 2511 collects the excess glue.

[0077] Curing operation: The electric screw 503 drives the rail plate 501 to descend, bringing the curing lamp 514 closer to the dispensing position. The pressure transmitter 507 detects the pressure of the pressure needle fixing block 511 to ensure that the pressure is appropriate. The curing lamp 514 is activated to cure the adhesive.

[0078] Reset and Cycle: After curing is complete, each component is reset, the finished product is removed, and if production needs to continue, the above steps are repeated; if production is stopped, the equipment is shut down, and each component returns to its origin.

[0079] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
