Description

Technical Field

[0002] In optical fiber communication and network construction, precise fixation of optical fiber connectors is a key step to ensure the stability and reliability of signal transmission. Traditional optical fiber fixing methods mainly rely on manual operation, which involves inserting the optical fiber into the central fiber hole of the optical fiber connector and filling glue in specific areas of the connector. In order to ensure the firm fixation of the optical fiber, multiple fillings are usually required, and after each filling, the connector needs to be placed in an oven for curing to form a stable bond.

[0036] The utility model provides Figures 1 to 5 As shown in the figure, a MT glue filling device is designed to solve the existing

[0037] The MT glue filling equipment mainly includes: a base 100, a fixture 200, a glue filler 300 and a laser sensor 400. The base 100 is used to provide a material for each component, and is generally placed on a horizontal ground when in use. The fixture 200, the glue filler 300 and the laser sensor 400 are respectively arranged on the base 100.

[0038] The fixture 200 is provided with a plurality of fixed stations 212, each of which is used to fix the optical fiber connector 800 to be filled with glue. In the actual assembly process, a plurality of optical fibers are first inserted into the optical fiber connector 800 for preliminary fixation, and then the assembled optical fibers and the optical fiber connector 800 are fixed on the fixture 200, and finally the windows to be filled with glue on the optical fiber connector 800 are filled with glue multiple times by the glue filler 300 so that the connection between the optical fibers and the optical fiber connector 800 meets the requirements.

[0039] Specifically, the present invention uses a glue filler 300 to fill the windows to be filled with glue on a plurality of fixed stations 212, and a laser sensor 400 is used to detect the height of the material on the plurality of fixed stations 212. For ease of description, the plurality of windows to be filled with glue are numbered as a, b, and c, and the glue filler 300 is used to fill a, b, and c with glue in sequence. When filling a, b, and c with glue or after all the filling with glue is completed, a, b, and c are heated to solidify the glue in a, b, and c. After the curing is completed, the relative heights of a, b, and c are respectively detected by the laser sensor 400 to obtain the thickness of the glue, so as to avoid the phenomenon of colloid protrusion.

[0040] With the rapid development of optical fiber communication technology, the production efficiency and quality requirements of optical fiber connector 800 are getting higher and higher. Although some automated glue filling devices have appeared on the market, aiming to reduce manual operations and improve production efficiency. However, the existing glue filling devices mainly achieve automation by controlling the amount of glue filling, and lack the ability to accurately control the thickness of the glue filling. This results in that in actual applications, the thickness of the colloid may be uneven, and even the colloid may bulge, which affects the sealing performance and long-term stability of the optical fiber connector 800, and further affects the performance of the entire optical fiber communication system.

[0041] The utility model sets a fixture 200 and a glue filler 300. After the assembled optical fiber and optical fiber connector 800 are fixed on the fixture 200, the glue filler 300 is used to fill the window to be filled with glue on the optical fiber connector 800. After each filling, the height of the material is detected by the laser sensor 400 to obtain the relative height of the material, so as to prevent the uneven thickness of the colloid from causing the colloid to bulge.

[0042] In some embodiments, Figures 1 to 5 As shown in the figure, the tooling fixture 200 includes: a tooling strip 210 and a fiber support strip 220. Both the tooling strip 210 and the fiber support strip 220 are arranged on the base 100, and a plurality of limit blocks 211 are arranged on the tooling strip 210, and a fixed position 212 is formed between every two adjacent limit blocks 211, and the fiber support strip 220 is used to support the optical fiber connected to the optical fiber connector 800.

[0043] Specifically, the tooling strip 210 and the fiber supporting strip 220 are arranged parallel to each other, and the assembled optical fiber and the optical fiber connector 800 are respectively perpendicular to the tooling strip 210 and the fiber supporting strip 220. The tooling strip 210 is fixed in the corresponding fixed station 212, and the fiber supporting strip 220 abuts against the optical fiber to support the optical fiber to prevent the optical fiber from bending downward excessively due to its own gravity and breaking.

[0044] In some embodiments, Figures 1 to 5 As shown in the figure, the tooling fixture 200 also includes: a plurality of negative pressure holes 213, the plurality of negative pressure holes 213 are respectively arranged on the tooling strip 210, the plurality of negative pressure holes 213 are respectively arranged in a plurality of fixed workstations 212 and correspond one-to-one with the plurality of fixed workstations 212, and the plurality of negative pressure holes 213 are used to fix the optical fiber connectors 800 in the plurality of fixed workstations 212.

[0045] Specifically, several negative pressure holes 213 are interconnected, and several negative pressure holes 213 are connected to negative pressure devices, such as vacuum pumps, which can provide negative pressure to the several negative pressure holes 213. When the optical fiber connector 800 is fixed in the fixed workstation 212, the corresponding negative pressure holes 213 can provide negative pressure to the partial structure of the tooling strip 210 in the fixed workstation 212, so that the optical fiber connector 800 is attracted and tightly attached to the tooling strip 210. The negative pressure attraction between the fixed workstation 212 and the negative pressure holes 213 can avoid displacement during the glue filling process of the optical fiber connector 800, which affects the glue filling effect.

[0046] In some embodiments, Figures 1 to 5 As shown in , the MT glue filling device also includes: a CCD camera 500, which is connected to the glue filler 300 and is arranged toward the glue filling needle of the glue filler 300, and the CCD camera 500 is used to detect the distance between the glue filling needle of the glue filler 300 and the material.

[0047] In actual use, when glue filling begins, the position of the glue filling needle of the glue filling device 300 can be obtained through the CCD camera 500 to complete the height calibration. The glue filling needle is the glue discharge structure of the glue filling device 300, which is used to fill the window to be filled with glue. During the glue filling process, the distance between the glue filling needle and the material can be obtained through the CCD camera 500 to prevent the distance between the glue filling needle and the material from being too small to crush the glue filling needle and the material. The distance between the glue filling needle and the material can also be set as needed to determine the thickness of the glue filling.

[0048] In some embodiments, the MT glue filling equipment further includes: a heater (shown in the figure), which is disposed on the tooling bar 210 and is thermally connected to the tooling bar 210 . The heater is used to fix the optical fiber connectors 800 in several fixed stations 212 .

[0049] Specifically, after the optical fiber is fixed on the optical fiber connector 800, it is necessary to fill glue two or three times. After each filling of glue, the optical fiber connector 800 needs to be heated for curing. The heater can be a heating resistor or other device that can emit a temperature exceeding 25 degrees Celsius. After generating heat, the heat can be transferred to the optical fiber connector 800 to heat the glue for curing.

[0050] In some embodiments, Figures 1 to 5 As shown in , the MT glue filling device also includes: a timing module, the timing module is electrically connected to the heater, and the timing module is used to record the working time of the heater.

[0051] Specifically, the heating time after glue filling is required, which is generally five minutes. When glue filling device 300 is used to fill a, b, and c in sequence, a, b, and c are heated when filling a, b, and c, and the working time of the heater is recorded by the timing module. When the heating time of a reaches the requirement (five minutes), the next glue filling work can be carried out.

[0052] In some embodiments, Figures 1 to 5 As shown in , the MT filling device also includes: a first driver 610, the first driver 610 is arranged on the base 100, and a plurality of fixed stations 212 are arranged at intervals along the X-axis direction. The glue filler 300 or the glue filler 300 is driven by the first driver 610 to move linearly to pass the glue filler 300 through the plurality of fixed stations 212 in sequence along the X-axis direction, so that the glue filler 300 can fill the glue filling windows on the plurality of fixed stations 212 in sequence.

[0053] In some embodiments, Figures 1 to 5 As shown in , the laser sensor 400 is connected to the glue filling device 300;

[0054] The MT glue filling device further includes: a second driver 620 , which is disposed on the base 100 . The glue filling device 300 is driven by the second driver 620 to move in the Y-axis direction, and the Y-axis direction is perpendicular to the X-axis direction.

[0055] Specifically, the laser sensor 400 and the glue filler 300 can be moved in the Y-axis direction through the second driver 620. Since the laser sensor 400 and the glue filler 300 do not work at the same time during actual use of the device, the laser sensor 400 and the glue filler 300 can be moved in the Y-axis direction through the second driver 620 to align the laser sensor 400 and the glue filler 300 with several filling windows in turn.

[0056] In some embodiments, Figures 1 to 5 As shown in , the MT glue filling equipment also includes: a photo positioning camera 700, which is connected to the glue filling device 300, and the photo positioning camera 700 is used to detect the positions of the optical fiber connectors 800 on several fixed stations 212.

[0057] Specifically, after the device is started, the photo positioning camera 700 can be used to quickly take photos to locate several optical fiber connectors 800 to obtain the position of the window to be filled with glue for each product. It should be noted that in the process of obtaining the position of the window to be filled with glue for each product by using the photo positioning camera 700, the position of the window to be filled with glue can be obtained by manual marking or computer calculation, and this method is a prior art.

[0058] In some embodiments, Figures 1 to 5 As shown in , the fixture 200 and the first driver 610 are each provided with two;

[0059] The first driver 610 includes: a first slide rail 611 and a first moving platform 612. The first slide rail 611 is arranged on the base 100 along the X-axis direction. The first moving platform 612 is slidably arranged on the first slide rail 611. The first moving platform 612 is driven by the first slide rail 611 to move linearly along the X-axis direction. The two fixtures 200 are respectively arranged on the two first moving platforms 612.

[0060] The second driver 620 includes: a second slide rail 621 and a second movable platform 622. The second slide rail 621 is set on the base 100 along the Y-axis direction. The second movable platform 622 is slidably set on the second slide rail 621, and the second movable platform 622 is set above the two first movable platforms 612. The second movable platform 622 is driven by the second slide rail 621 to move linearly along the Y-axis direction. The glue filler 300 and the laser sensor 400 are respectively set on the two second movable platforms 622.

[0061] Specifically, the first driver 610 can drive the corresponding fixture 200 to move linearly along the X-axis direction. Since the glue filling device 300, the laser sensor 400, the camera 700 and other devices cannot move linearly along the X-axis direction, the fixture 200 can pass through the glue filling device 300 in sequence under the drive of the first driver 610 to complete the glue filling and other tasks.

[0062] The second driver 620 can drive the glue filler 300, the laser sensor 400, the photo positioning camera 700 and other devices to move linearly along the Y-axis direction. Since the tooling fixture 200 cannot move linearly along the Y-axis direction, the glue filler 300, the laser sensor 400, the photo positioning camera 700 and other devices can be driven by the second driver 620 to align the glue filler 300, the laser sensor 400, the photo positioning camera 700 and other devices with the glue filling window in turn. Through the cooperation of the first driver 610 and the second driver 620, the glue filler 300, the laser sensor 400, the photo positioning camera 700 and other devices can be aligned with any glue filling window.

[0063] In summary, a fiber optic connector glue filling device is provided, including a base, a fixture, a glue filler and a laser sensor. The fixture, the glue filler and the laser sensor are respectively arranged on the base. The fixture is provided with a plurality of fixed stations, and the plurality of fixed stations are used to fix the fiber optic connector to be glued. The glue filler is used to fill the materials on the plurality of fixed stations, and the laser sensor is used to detect the height of the materials on the plurality of fixed stations. The utility model provides a fixture and a glue filler, and after the assembled optical fiber and the fiber optic connector are fixed on the fixture, the glue filler is used to fill the window to be glued on the fiber optic connector. After each glue filling is completed, the height of the material is detected by the laser sensor to obtain the relative height of the material, so as to prevent the uneven thickness of the colloid from causing the colloid to bulge.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
