Description

Technical Field

[0001] The present invention relates to the field of optical fiber communication technology, and mainly to an automated optical fiber array assembly device and a working method. Background Art

[0002] Fiber optic arrays use V-grooves to mount an optical fiber, a bundle of optical fibers, or an optical fiber ribbon on an array substrate. Optical fibers are mainly composed of three parts, and their cross-sections are theoretically three concentric circles, including coating, cladding, and core from the outside to the inside. Fiber optic arrays are mainly used to directly transmit images. Many optical fibers are arranged in a certain order to form a required geometric shape, and the core ends are aligned to form a fiber optic array. The fiber arrangement positions at both ends of the array correspond to each other. One optical fiber in the array is equivalent to a pixel, and the light image at one end of the fiber optic array will be reproduced at the other end of the array.

[0003] The assembly device in the prior art can only produce a single optical fiber array each time by manual means. After the single optical fiber array cover is prepared, it is allowed to stand, glue is dispensed and exposed. The standing, glue dispensing and exposure process usually takes more than 300 seconds. At this time, the equipment and workers are in a waiting state. After standing, exposure is performed. After the exposure is completed, the optical fiber array is removed, and the next array is produced or assembled separately on different assembly devices. Each assembly takes a long time, the waiting time is long, the work efficiency is low, and the idle time of the equipment and workers is long. It is impossible to realize the automated operations of threading the optical fiber, placing the cover, glue dispensing and exposure to improve work efficiency.

The video auxiliary unit 8 can also observe the position of glue injection and the flow direction of glue during glue injection, so that the operator can make timely adjustments according to actual conditions, thereby reducing the scrap rate of the optical fiber array 100 and improving product quality.

[0084] In this embodiment, the video auxiliary unit 8 is a camera and a display screen, and the camera feeds back the production status to the display screen in real time. In other embodiments, the video auxiliary unit 8 can also be other real-time monitoring devices, which is not specifically limited in this embodiment.

[0085] This embodiment also provides a working method of an automated optical fiber array assembly device, which is as follows:

[0086] S100: The optical fiber array 100 is manufactured by the manufacturing unit 2 at the manufacturing station;

[0087] Specifically, the adsorption unit 5 adsorbs a cover plate 101, and places the cover plate 101 in the fixed position of the production unit 2 through the moving unit 3. The first fixed block 231 is driven by the first driving component to move to a position close to the coating 103, and the second fixed block 241 is driven by the second driving component to move to a position close to the fiber core 102. The operator passes the fiber core 102 through the first fixed block 231 and the second fixed block 241 in sequence. Since the second fixed block 241 only allows the fiber core 102 to pass through, the first fixed block 231 can fix the coating 103. Therefore, the fiber core 102 with the coating 103 stripped off passes through the second fixed block 241. The fiber core 102 is fixed in the groove corresponding to the cover plate 101 that has been placed in the fixed position, and the fiber core 102 is partially observed through the video auxiliary unit 8, and the position of the fiber core 102 is adjusted so that each fiber core is located in the corresponding groove, and the fiber core 102 is aligned. The adsorption unit 5 adsorbs another cover plate 101, and the other cover plate 101 is placed on the cover plate 101 that has been placed in the fixed position through the moving unit 3. The production unit 2 presses the two cover plates 101 by adjusting the clamping assembly 22, and the moving unit 3 drives the glue dispensing unit 4 to dispense glue on the two cover plates 101 and the fiber core 102. At this point, the optical fiber array 100 is completed.

[0088] S200: Determine the number and order of exposure stations corresponding to the manufactured optical fiber array 100 according to the preset exposure time of the optical fiber array 100.

[0089] For example, assuming that the exposure and curing time required for the optical fiber array 100 in this embodiment is 300s, 6 exposure stations are provided, and the exposure and curing time of each exposure station is set to 50s, then this optical fiber array 100 needs to pass through the 6 exposure stations in sequence and then the unloading robot 6 moves the exposed optical fiber array 100 to the conveyor belt 7 so that it meets the required exposure and curing time.

[0090] In this embodiment, the exposure time of the optical fiber array 100 is changed by setting a fixed exposure time for the exposure unit 1, and the optical fiber array 100 is exposed through different numbers of exposure stations, thereby adapting to different requirements of the optical fiber array 100. In other embodiments, the exposure time of the exposure unit 1 can also be changed, and the exposure time of the optical fiber array 100 can also be changed, which is not specifically limited in this embodiment.

[0091] For example, if it is assumed that the exposure and curing time required for the optical fiber array 100 is 150s, 6 exposure stations are provided, and the exposure and curing time of each exposure station is set to 50s, then the optical fiber array 100 can be controlled to pass through any 3 exposure stations for exposure and curing, and then the exposed optical fiber array 100 can be moved to the conveyor belt 7 by the unloading robot 6 to meet the required exposure and curing time. The exposure and curing time of each exposure station can also be changed to 25s, and the optical fiber array 100 can be controlled to pass through 6 exposure stations and then the exposed optical fiber array 100 can be moved to the conveyor belt 7 by the unloading robot 6 to meet the preset exposure time. In other embodiments, the number of exposure units 1 and the number of production units 2 can be increased according to different production requirements, thereby increasing the number of exposure stations to meet different production requirements, and this embodiment does not specifically limit this.

[0092] Preferably, before step S200, the completed optical fiber array 100 is rotated along its own axis by one of the first platform 300 and the second platform 400, and the relative positions of the production unit 2 and the exposure unit 1 are changed, so that the completed optical fiber array 100 is transferred to the static station for static placement, and at the same time, the production station produces subsequent optical fiber arrays 100.

[0093] S300: The relative positions of the production unit 2 and the exposure unit 1 are changed by rotating one of the first platform 300 and the second platform 400 along its own axis, thereby controlling the completed optical fiber array 100 to pass through a determined exposure station. While the completed optical fiber array 100 is exposed and cured, the optical fiber array 100 is continuously produced on the production unit 2 of the production station.

[0094] Specifically, the completed optical fiber array 100 rotates along its own axis through one of the first platform 300 and the second platform 400, thereby entering the first exposure station, and the subsequently completed optical fiber array 100 enters the static station for static placement, and so on. When the optical fiber array 100 at the first exposure station enters the second exposure station, the optical fiber array 100 at the static station enters the first exposure station, and the optical fiber array 100 at the manufacturing station enters the static station, thereby realizing the automated assembly line operation of the optical fiber array 100.

[0095] After step S300, the optical fiber array 100 passes through multiple exposure stations and reaches the preset exposure curing time. At the position of the last exposure station, the optical fiber array 100 that has completed exposure is moved to the conveyor belt 7 by the unloading robot 6. At this point, the exposure of the optical fiber array 100 is completed, and the subsequent optical fiber arrays 100 that have reached the exposure time are also moved to the conveyor belt 7 in sequence by the unloading robot 6.

[0096] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
