[0002] The main function of a fiber optic connector is to precisely align optical fibers to achieve effective transmission of optical signals. Fiber optic connectors are often required to provide telecommunication connections in medical devices or other electronic products requiring high reliability.

[0016] Preferably, a plurality of connecting columns are fixedly installed on the side of the third ring facing the second ring.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The optical fiber connector welding device described in the present invention positions the optical fiber connector inside it through a positioning ring, and two air suction components are attached together. The connection position of the optical fiber connector is between the two air suction components. The annular air bag is inflated and attached to the outside of the corresponding optical fiber connector, so that the two air suction components cover and wrap the outside of the connection parts of the two optical fiber connectors. When the two optical fiber connectors are driven by the positioning ring to move and rotate and continue to be connected, the multiple air guide structures arranged inside the second circular ring can perform air extraction. When the welding head is required to weld the optical fiber connector, the optical fiber connector is in a near vacuum state, which can effectively increase the effect of airtight welding. In subsequent welding, due to the low air content inside the optical fiber connector, heat is more difficult to transfer.

[0020] 2. The optical fiber connector welding device described in the present invention is driven by electricity to move multiple positioning blocks and round blocks toward the center position of the positioning ring, clamping the optical fiber connector inside the positioning ring at this time, thereby completing the positioning work. The setting of the round block can ensure that the optical fiber connector is positioned at the center position of the positioning ring. When the positioning ring needs to drive the optical fiber connector to rotate, it is driven by a driving motor, and the gear at the output end of the driving motor is engaged with the tooth groove. Therefore, after the driving motor is driven, the tooth groove drives the optical fiber connector to rotate, thereby completing the connection of the optical fiber connector. The diameters of the multiple arc bars are different, which match the multiple arc grooves with different diameters, and cooperate with the positioning ring to rotate to prevent the positioning ring from rotating out of position.

[0021] 3. The optical fiber connector welding device described in the present invention draws out the air in the space surrounded by the two suction components and the space where the two optical fiber connectors are connected, and guides the air to a distant place through an air duct. At this time, the subsequent air tightness requirements can be better met. When the two suction components move until they are in contact with each other, rubber rings of different diameters are in contact with the corresponding side surfaces of the second circular ring, which can further improve the sealing of the space wrapped by the two suction components. The output end of the telescopic cylinder passes through the storage block and extends to the inside of the arc-shaped movable groove, and is connected to the corresponding side surface of the first circular ring. The movement of the suction component is realized by the extension and contraction of the storage block. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1: Figure 1-4 and Figure 6-8As shown, an optical fiber connector welding device according to an embodiment of the present invention includes a welding box 1 and a welding head 2 installed on the side of the welding box 1 through a line. A welding auxiliary frame 3 is fixedly installed above the welding box 1. Two positioning components 4 and an airtight component 5 are movably installed above the welding auxiliary frame 3. The airtight component 5 is located in the middle of the two positioning components 4.

[0035] The positioning assembly 4 includes an electric moving block 6 movably mounted above the welding auxiliary frame 3 and a positioning ring 7 movably mounted above the electric moving block 6. The airtight assembly 5 includes a storage block 8 movably mounted above the welding auxiliary frame 3 and two suction assemblies 9 movably mounted above the storage block 8.

[0036] The air suction assembly 9 includes a second ring 92 and a first ring 91 installed on one side of the second ring 92 . An air guide structure 96 is movably installed inside the second ring 92 , and an annular airbag 911 is installed on the inner side wall of the first ring 91 .

[0037] Specifically, when it is necessary to perform airtight welding on the optical fiber connectors of medical equipment, first insert the two optical fiber connectors into the corresponding positioning rings 7 and the inside of the suction component 9 respectively, and make a preliminary connection between the two optical fiber connectors. At this time, the connection parts of the two optical fiber connectors are in the middle position of the two suction components 9, and the optical fiber connectors inside are positioned by the positioning ring 7. At this time, the subsequent connection of the optical fiber connectors can be completed by moving and rotating the two positioning rings 7 without manual work. At this time, the two suction components 9 are attached together, and the connection position of the optical fiber connector is between the two suction components 9. Under electric drive, the annular airbag 911 inside the first ring 91 is inflated and attached to the outside of the corresponding optical fiber connector to maintain a certain airtightness, so that the two suction components 9 cover and wrap the outside of the connection parts of the two optical fiber connectors. When the two optical fiber connectors are driven by the positioning ring 7 to move and rotate to continue to connect, the second ring 92 The multiple air guide structures 96 arranged inside can perform the vacuum function, and guide the internal gas of the two suction components 9 and the gas at the connection parts of the two optical fiber connectors to the outside. That is, when the welding head 2 is needed to weld the optical fiber connector, the optical fiber connector is in a near-vacuum state, which can effectively increase the effect of airtight welding. In subsequent welding, due to the low air content inside the optical fiber connector, heat is more difficult to transfer, further reducing the impact of subsequent welding heat on the optical fiber inside the optical fiber connector. When the vacuum work and the installation of the two optical fiber connectors are completed, the annular airbag 911 is vacuumed and shrunk. Driven by electricity, the two suction components 9 move back to back, revealing the connection position of the optical fiber connector, and then the connection position of the optical fiber connector is driven to rotate by the two positioning rings 7. At this time, you only need to take the welding head 2 to weld one point, and with the cooperation of the rotation action of the connection position of the optical fiber connector, a better airtight welding effect is achieved.

[0038] like Figure 2 As shown, side frames 31 are fixedly installed at both ends of the welding auxiliary frame 3, and multiple guide rails 32 are installed above the welding auxiliary frame 3. The two ends of the multiple guide rails 32 are connected to the side edges of the corresponding side frames 31. The positioning component 4 and the airtight component 5 move above the welding auxiliary frame 3 through the setting of the multiple guide rails 32.

[0039] like Figure 3-5 As shown, an arc-shaped mounting groove 61 is opened inside the upper part of the electric moving block 6, a plurality of arc-shaped bars 62 are fixedly mounted on the inner walls on both sides of the arc-shaped mounting groove 61, and a driving motor 63 is fixedly mounted on the side of the electric moving block 6.

[0040] There are multiple arc grooves 71 on both sides of the positioning ring 7, and multiple component grooves 72 are also provided inside the positioning ring 7. Positioning blocks 74 are movably installed inside the multiple component grooves 72. A round block 75 is installed on the side of the multiple positioning blocks 74 facing the center position of the positioning ring 7. The multiple positioning blocks 74 move inside the component groove 72 through the electric drive principle. A tooth groove 73 is provided on the outside of the positioning ring 7, and the lower end of the positioning ring 7 is movably installed inside the arc-shaped installation groove 61.

[0041] The arc groove 71 matches the corresponding arc strip 62 , and one end of the output shaft of the driving motor 63 matches the outer side of the tooth groove 73 , driving the positioning ring 7 to rotate.

[0042] Specifically, when the positioning ring 7 is needed to position the optical fiber connector, the electric moving block 6 can first drive the positioning ring 7 to move above the welding auxiliary frame 3, and then match the required positioning position of the optical fiber connector. After the position is determined, the multiple positioning blocks 74 and the round block 75 are all moved toward the center position of the positioning ring 7 under electric drive, and the optical fiber connector that is now inside the positioning ring 7 is clamped, thereby completing the positioning work. The setting of the round block 75 can ensure that the optical fiber connector is positioned in the center position of the positioning ring 7. When the positioning ring 7 is needed to drive the optical fiber connector to rotate, it is driven by the driving motor 63. The gear at the output end of the driving motor 63 is engaged with the tooth groove 73. Therefore, after the driving motor 63 is driven, the tooth groove 73 drives the optical fiber connector to rotate, thereby completing the connection of the optical fiber connector. The multiple arc bars 62 have different diameters, which match the multiple arc grooves 71 with different diameters, and rotate with the positioning ring 7 to prevent the positioning ring 7 from rotating out of position.

[0043] like Figure 6-9 As shown, an arc-shaped movable groove 81 is opened inside the upper part of the storage block 8, and a plurality of rail grooves 82 are opened inside the arc-shaped movable groove 81. The suction component 9 is movably installed inside the arc-shaped movable groove 81, and the suction component 9 moves inside the arc-shaped movable groove 81 by matching with the rail groove 82.

[0044] A rubber ring 921 is installed on the side of the second ring 92 facing the other air intake component 9 . A plurality of second component grooves 922 are opened inside the second ring 92 , and a plurality of air guide structures 96 are installed inside the corresponding second component grooves 922 .

[0045] A plurality of telescopic cylinders 95 are installed on the side of the suction component 9, and the plurality of telescopic cylinders 95 are fixedly installed on the outside of the storage block 8. A third ring 93 is movably installed on the side of the first ring 91 away from the second ring 92. An air pump 94 is fixedly installed above the suction component 9, and an air guide pipe 941 is fixedly installed above the air pump 94.

[0046] A plurality of connecting posts 931 are fixedly mounted on one side of the third ring 93 facing the second ring 92 . The connecting posts 931 penetrate the first ring 91 and the second ring 92 and extend into the corresponding component groove 2 922 . A ring strip 932 is mounted on one end of the connecting post 931 .

[0047] Specifically, when the two suction components 9 are attached to each other and are in the middle position of the arc-shaped movable groove 81, the annular airbags 911 provided in the suction components 9 are inflated, and the two suction components 9 cover the outside of the connection position of the optical fiber connector. Driven by the air pump 94, multiple air guide structures 96 produce a suction effect, and the air in the space wrapped by the two suction components 9 and the space of the connection position of the two optical fiber connectors is extracted, and the air is guided to a distant place through the air guide tube 941. At this time, the subsequent air tightness requirements can be better met. When the two suction components 9 move until they are attached to each other, the rubber rings 921 of different diameters are attached to the corresponding sides of the second circular ring 92, which can further improve the sealing of the space wrapped by the two suction components 9. The output end of the telescopic cylinder 95 passes through the storage block 8 and extends to the inside of the arc-shaped movable groove 81, and is connected to the side of the corresponding first circular ring 91. The movement of the suction component 9 is realized by the extension and contraction of the storage block 8.

[0048] Example 2: Figure 9 As shown, comparative example one, another embodiment of the present invention is: the air guide structure 96 includes a connecting pipe 961 installed inside the component groove 922, one end of the multiple connecting pipes 961 is coiled inside the second ring 92 and are all connected to the air pump 94, the air guide structure 96 also includes an air suction head 962 fixedly installed at one end of the connecting pipe 961 and a disc 963 fixedly installed at one end of the connecting pipe 961, an annular spring 964 is fixedly installed above the disc 963, and the upper end of the annular spring 964 is fixedly connected to the inner wall of the component groove 922.

[0049] Specifically, when the two suction components 9 are attached to each other, the annular spring 964 is in a natural state, and the multiple connecting tubes 961 are in a vertical state. When the vacuum work at the connection position of the optical fiber connector is completed and welding is required, the two suction components 9 are moved back to back by the telescopic drive of the telescopic cylinder 95 until the third ring 93 contacts the inner wall of the arc-shaped movable groove 81 and pressure is applied to the third ring 93 to move it toward the first ring 91. At this time, the connection position of the optical fiber connector is exposed, and the two optical fiber connectors can be driven to rotate by the two positioning rings 7 to facilitate the subsequent airtight welding of the welding head 2. When the suction component 9 moves back to When in the extreme position, the third ring 93 is squeezed, and the third ring 93 will drive the connecting column 931 and the ring strip 932 to move toward the first ring 91. At this time, the ring strip 932 pushes the corresponding end of the connecting tube 961 and the suction head 962 to bend, so that the multiple suction heads 962 provided in the two suction components 9 are bent toward the center position of the two suction heads 962 at the same time. At this time, the annular spring 964 is bent at the same time, and the welding head 2 is taken to weld the optical fiber connector. The multiple suction heads 962 bent in the direction perform exhaust work to remove the heat generated by welding as soon as possible to avoid the overheated welding environment from affecting the optical fiber of the optical fiber connector.

[0050] Working principle: When it is necessary to perform airtight welding on the optical fiber connectors of medical equipment, first insert the two optical fiber connectors into the corresponding positioning rings 7 and the inside of the suction component 9 respectively, and make a preliminary connection between the two optical fiber connectors. At this time, the connection parts of the two optical fiber connectors are in the middle of the two suction components 9. The optical fiber connectors inside are positioned by the positioning ring 7. At this time, the subsequent connection of the optical fiber connectors can be completed by moving and rotating the two positioning rings 7 without manual work. At this time, the two suction components 9 are attached together, and the connection position of the optical fiber connector is between the two suction components 9. Under electric drive, the annular airbag 911 inside the first ring 91 is inflated and attached to the outside of the corresponding optical fiber connector to maintain a certain airtightness. The two suction components 9 are covered and wrapped around the outside of the connection parts of the two optical fiber connectors. When the two optical fiber connectors are driven by the positioning ring 7 to move and rotate to continue to connect, the multiple air guide structures 96 set inside the second ring 92 can perform the suction effect, and guide the internal gas of the two suction components 9 and the gas at the connection parts of the two optical fiber connectors to the outside. That is, when the welding head 2 is needed to weld the optical fiber connectors, the optical fiber connectors are in a near-vacuum state, which can effectively increase the effect of airtight welding. After the suction work and the installation of the two optical fiber connectors are completed, the annular airbag 911 is evacuated and shrunk. Driven by electricity, the two suction components 9 move back to back, revealing the connection position of the optical fiber connectors, and then through the two positioning rings 7 drives the connection position of the optical fiber connector to rotate. At this time, you only need to take the welding head 2 to weld at one point. With the cooperation of the rotation action of the connection position of the optical fiber connector, a better airtight welding effect is achieved. When the two suction components 9 are attached to each other, the annular spring 964 is in a natural state, and the multiple connecting tubes 961 are in a vertical state. When the vacuum work at the connection position of the optical fiber connector is completed, welding needs to be performed. The two suction components 9 are moved back to back by the telescopic drive of the telescopic cylinder 95 until the third ring 93 contacts the inner wall of the arc-shaped movable groove 81 and pressure is applied to the third ring 93 to make it move toward the first ring 91. At this time, the connection position of the optical fiber connector is revealed, and the two optical fiber connectors can be driven by the two positioning rings 7. The head rotates to facilitate the subsequent airtight welding of the welding head 2. When the suction component 9 moves back to the extreme position, the third ring 93 is squeezed, and the third ring 93 will drive the connecting column 931 and the ring strip 932 to move toward the first ring 91. At this time, the ring strip 932 pushes the corresponding end of the connecting tube 961 and the suction head 962 to bend, so that the multiple suction heads 962 set in the two suction components 9 are all bent toward the center position of the two suction heads 962 at the same time. At this time, the annular spring 964 is bent at the same time, and the welding head 2 is taken to weld the optical fiber connector. The multiple suction heads 962 bent in the direction perform exhaust work to remove the heat generated by welding as soon as possible to avoid the overheated welding environment from affecting the optical fiber of the optical fiber connector.
