Description

Technical Field

[0001] The present invention belongs to the field of joint welding devices, and more specifically, it is an optical fiber joint welding device. Background Art

[0002] The main function of an optical fiber joint (optical fiber connector) is to accurately align optical fibers to achieve effective transmission of optical signals. In medical devices or other electronic products that require high reliability, optical fiber joints are usually needed to provide telecommunication connections. Especially in medical devices, there are relatively high requirements for telecommunication connections. Usually, for medical environment considerations, welding technology is used to hermetically seal the connection of optical fiber joints.

[0008] Preferably, side frames are fixedly installed at both ends of the welding auxiliary frame. A plurality of guide rails are installed above the welding auxiliary frame, and both ends of the plurality of guide rails are connected to the sides of the corresponding side frames. The positioning assembly and the airtightness assembly move above the welding auxiliary frame through the arrangement of the plurality of guide rails.

[0009] Preferably, an arc-shaped installation groove is formed inside the upper part of the electric moving block. A plurality of arc-shaped strips are fixedly installed on both inner walls of the arc-shaped installation groove. A driving motor is fixedly installed on the side of the electric moving block.

[0010] Preferably, a plurality of arc-shaped grooves are formed on both sides of the positioning ring. A plurality of component grooves I are further formed inside the positioning ring. A plurality of positioning blocks are movably installed inside the plurality of component grooves I. A round block is installed on one side of the plurality of positioning blocks facing the center position of the positioning ring. The plurality of positioning blocks move inside the component groove I through the principle of electric drive. A toothed groove is formed on the outer side of the positioning ring. The lower end of the positioning ring is movably installed inside the arc-shaped installation groove.

[0011] Preferably, the arc-shaped groove matches the corresponding arc-shaped strip, and one end of the output shaft of the driving motor matches the outer side of the toothed groove to drive the positioning ring to rotate.

[0012] Preferably, an arc-shaped moving groove is formed inside the upper part of the placement block. A plurality of track grooves are formed inside the arc-shaped moving groove. The air suction assembly is movably installed inside the arc-shaped moving groove, and the air suction assembly moves inside the arc-shaped moving groove through matching with the track grooves.

[0013] Preferably, a rubber ring is installed on the side of the second ring facing the other air suction assembly. A plurality of component grooves II are formed inside the second ring. A plurality of air guiding structures are installed inside the corresponding plurality of component grooves II.

[0014] Preferably, a plurality of telescopic cylinders are installed on the side of the air suction assembly. The plurality of telescopic cylinders are fixedly installed on the outer side of the placement block. A third ring is movably installed on the side of the first ring away from the second ring. An air pump is fixedly installed above the air suction assembly. A gas guide pipe is fixedly installed above the air pump.

[0015] Preferably, a plurality of connecting columns are fixedly installed on the side of the third ring facing the second ring. The connecting columns penetrate through the first ring and the second ring and extend into the corresponding component grooves II. A ring strip is installed at one end of the connecting column.

[0016] Preferably, the air guiding structure includes a connecting pipe installed inside the second component groove. One ends of multiple said connecting pipes are coiled inside the second ring and are all connected to an air pump. The air guiding structure further includes a suction head fixedly installed at one end of the connecting pipe and a disc fixedly installed at one end of the connecting pipe. An annular spring is fixedly installed above the disc, and the upper end of the annular spring is fixedly connected to the inner wall of the second component groove.

[0017] The beneficial effects of the present invention are as follows: 1. For the fiber optic connector welding device of the present invention, the fiber optic connector inside it is positioned by the positioning ring. The two suction components are attached to each other, and the connection position of the fiber optic connector is between the two suction components. The annular airbag is inflated and adheres to the outer side of the corresponding fiber optic connector, so that the two suction components cover and wrap the outer side of the connection part of the two fiber optic connectors. When the two fiber optic connectors are driven by the positioning ring to move and rotate for continuous connection, the multiple air guiding structures arranged inside the second ring can perform a pumping action. When the welding head is needed to weld the fiber optic connector, the fiber optic connector is in a near-vacuum state, which can effectively increase the effect of airtight welding. And during subsequent welding, because the air content inside the fiber optic connector is small, heat is more difficult to transfer.

[0018] 2. For the fiber optic connector welding device of the present invention, under the drive of electricity, multiple positioning blocks and round blocks all move towards the center of the positioning ring, clamping the fiber optic connector located inside the positioning ring at this time, thereby completing the positioning work. The setting of the round block can ensure that the fiber optic connector is positioned at the center of the positioning ring. When it is necessary to drive the fiber optic connector to rotate by the positioning ring, it is driven by a driving motor. The gear at the output end of the driving motor meshes with the tooth groove. Therefore, after the driving motor is driven, the tooth groove drives the fiber optic connector to rotate, thereby completing the connection of the fiber optic connector. The diameters of the multiple arc-shaped strips are different and match the multiple arc grooves with different diameters, and rotate with the positioning ring to prevent the positioning ring from rotating out of position.

[0019] 3. For the fiber optic connector welding device of the present invention, the air in the space wrapped by the two suction components and the space at the connection position of the two fiber optic connectors is pumped away and guided to a distance through the air duct. At this time, the subsequent airtightness requirements can be better met. When the two suction components move until they are attached to each other, the rubber rings with different diameters are attached to the side surfaces of the corresponding second rings, which can further improve the sealing performance inside the space wrapped by the two suction components. The output end of the telescopic cylinder penetrates through the placement block and extends into the arc-shaped moving groove, and is connected to the side surface of the corresponding first ring. The movement of the suction component is realized through the expansion and contraction of the placement block. Description of the Drawings

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] Embodiment 1: As shown in Figures 1-4 and Figures 6-8 A fiber optic 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 circuit. A welding auxiliary frame 3 is fixedly installed above the welding box 1, and two positioning assemblies 4 and an airtight assembly 5 are movably installed above the welding auxiliary frame 3. The airtight assembly 5 is located in the middle of the two positioning assemblies 4; The positioning component 4 includes an electrically movable block 6 movably installed above the welding auxiliary frame 3 and a positioning ring 7 movably installed above the electrically movable block 6. The airtight component 5 includes an object placing block 8 movably installed above the welding auxiliary frame 3 and two air suction components 9 movably installed above the object placing block 8.

[0025] The air suction component 9 includes a second circular ring 92 and a first circular ring 91 installed on one side of the second circular ring 92. An air guiding structure 96 is movably installed inside the second circular ring 92, and an annular airbag 911 is installed on the inner side wall of the first circular ring 91.

[0026] Specifically, when airtight welding of the optical fiber connectors of medical devices is required, first insert the two optical fiber connectors into the corresponding positioning ring 7 and the air suction components 9 respectively to preliminarily connect the two optical fiber connectors. At this time, the connection part of the two optical fiber connectors is in the middle position between the two air suction components 9. The optical fiber connector inside is positioned by the positioning ring 7. At this time, without manual operation, the subsequent connection of the optical fiber connectors can be completed by the movement and rotation of the two positioning rings 7. At this time, the two air suction components 9 are attached together, and the connection position of the optical fiber connectors is between the two air suction components 9. Under electric drive, the annular airbag 911 inside the first circular ring 91 is inflated and expands, sticking to the outer side of the corresponding optical fiber connector to maintain a certain airtightness, so that the two air suction components 9 cover and wrap the outer side of the connection part of the two optical fiber connectors. When the two optical fiber connectors are driven by the positioning ring 7 to move and rotate for further connection, the multiple air guiding structures 96 arranged inside the second circular ring 92 can perform air extraction, guiding the gas inside the two air suction components 9 and the gas at the connection part of the two optical fiber connectors to the outside together. That is, when the welding head 2 needs to weld the optical fiber connectors, the optical fiber connectors are in a near-vacuum state, which can effectively improve the effect of airtight welding. And during subsequent welding, because the air content inside the optical fiber connectors is small, heat is more difficult to transfer, further reducing the influence of the subsequent welding heat on the optical fibers inside the optical fiber connectors. After the air extraction work and the installation of the two optical fiber connectors are completed, the annular airbag 911 is deflated by air extraction. Under electric drive, the two air suction components 9 move away from each other, revealing the connection position of the optical fiber connectors. Subsequently, the connection position of the optical fiber connectors is rotated by driving the two positioning rings 7. At this time, only need to take the welding head 2 to weld at one point, and with the cooperation of the rotation action of the connection position of the optical fiber connectors, better-effect airtight welding can be completed.

[0027] As Figure 2 shown, side frames 31 are fixedly installed at both ends of the welding auxiliary frame 3, and a plurality of guide rails 32 are installed above the welding auxiliary frame 3. Both ends of the plurality of 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 arrangement of the plurality of guide rails 32.

[0028] As Figures 3-5As shown, an arc-shaped installation groove 61 is formed inside the upper part of the electric moving block 6. A plurality of arc-shaped strips 62 are fixedly installed on the inner walls on both sides of the arc-shaped installation groove 61. A driving motor 63 is fixedly installed on the side of the electric moving block 6.

[0029] A plurality of arc-shaped grooves 71 are formed on both sides of the positioning ring 7. A plurality of component grooves I 72 are further formed inside the positioning ring 7. A positioning block 74 is movably installed inside a plurality of component grooves I 72. A round block 75 is installed on one side of a plurality of positioning blocks 74 facing the center position of the positioning ring 7. A plurality of positioning blocks 74 move inside the component groove I 72 by the principle of electric drive. A tooth groove 73 is formed on the outer side of the positioning ring 7. The lower end of the positioning ring 7 is movably installed inside the arc-shaped installation groove 61.

[0030] The arc-shaped groove 71 matches the corresponding arc-shaped strip 62. One end of the output shaft of the driving motor 63 matches the outer side of the tooth groove 73 to drive the positioning ring 7 to rotate.

[0031] Specifically, when the positioning ring 7 is required to position the fiber optic connector, first, the electric moving block 6 can drive the positioning ring 7 to move above the welding auxiliary frame 3, so as to match the required positioning position of the fiber optic connector. After the position is determined, under the electric drive, a plurality of positioning blocks 74 and the round block 75 both move towards the center position of the positioning ring 7 to clamp the fiber optic connector inside the positioning ring 7 at this time, thus completing the positioning work. The setting of the round block 75 can ensure that the fiber optic connector is positioned at the center position of the positioning ring 7. When the positioning ring 7 is required to drive the fiber optic connector to rotate, it is driven by the driving motor 63. The gear at the output end of the driving motor 63 meshes with the tooth groove 73. Therefore, after the driving motor 63 is driven, the tooth groove 73 drives the fiber optic connector to rotate, thus completing the connection of the fiber optic connector. The diameters of a plurality of arc-shaped strips 62 are different and match a plurality of arc-shaped grooves 71 with different diameters, and cooperate with the positioning ring 7 to rotate to prevent the positioning ring 7 from rotating out of position.

[0032] As Figures 6-9 shown, an arc-shaped moving groove 81 is formed inside the upper part of the placement block 8. A plurality of rail grooves 82 are formed inside the arc-shaped moving groove 81. The air suction assembly 9 is movably installed inside the arc-shaped moving groove 81, and the air suction assembly 9 moves inside the arc-shaped moving groove 81 by matching with the rail grooves 82.

[0033] A rubber ring 921 is installed on the side of the second ring 92 facing the other air suction assembly 9. A plurality of component grooves II 922 are formed inside the second ring 92. A plurality of air guiding structures 96 are installed inside a plurality of corresponding component grooves II 922.

[0034] A plurality of telescopic cylinders 95 are installed on the side of the air suction assembly 9. The plurality of telescopic cylinders 95 are fixedly installed on the outside of the placement 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 air suction assembly 9, and an air duct 941 is fixedly installed above the air pump 94.

[0035] A plurality of connecting columns 931 are fixedly installed on the side of the third ring 93 facing the second ring 92. The connecting columns 931 penetrate through the first ring 91 and the second ring 92 and extend into the corresponding component groove two 922. One end of the connecting column 931 is installed with a ring strip 932.

[0036] Specifically, when two air suction assemblies 9 are attached to each other and are at the middle position of the arc-shaped moving groove 81, at this time, the annular air bags 911 provided in the air suction assemblies 9 are all inflated. The two air suction assemblies 9 cover and wrap the outside of the connection position of the optical fiber connector. Driven by the air pump 94, a plurality of air guiding structures 96 generate a pumping effect to suck out the air in the space wrapped by the two air suction assemblies 9 and the space at the connection position of the two optical fiber connectors, and guide it to a distant place through the air duct 941. At this time, the subsequent airtightness requirements can be better completed. When the two air suction assemblies 9 move until they are attached to each other, the rubber rings 921 with different diameters are attached to the side of the corresponding second ring 92, which can further improve the sealing performance in the space wrapped by the two air suction assemblies 9. The output end of the telescopic cylinder 95 penetrates through the placement block 8 and extends into the arc-shaped moving groove 81, and is connected to the side of the corresponding first ring 91. The movement of the air suction assembly 9 is realized by the expansion and contraction of the placement block 8.

[0037] Embodiment 2: As Figure 9 shown, compared with Embodiment 1, another implementation manner of the present invention is: the air guiding structure 96 includes a connecting pipe 961 installed inside the component groove two 922. One end of the plurality of connecting pipes 961 is coiled inside the second ring 92 and is connected to the air pump 94. The air guiding structure 96 further includes a 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 two 922.

[0038] Specifically, when the two air suction components 9 are in contact with each other, the annular spring 964 is in a natural state and the plurality of connecting pipes 961 are in a vertical state. After the air extraction work for the fiber optic connector connection position is completed and welding is required, through the telescopic drive of the telescopic cylinder 95, the two air suction components 9 move away from each other until the third ring 93 contacts the inner wall of the arc-shaped moving groove 81 and a pressure is applied to the third ring 93 to move it in the direction of the first ring 91. At this time, the connection position of the fiber optic connector is exposed, and the two fiber optic connectors can be rotated by the two positioning rings 7 to facilitate the airtight welding of the subsequent welding head 2. When the air suction component 9 moves away from each other to the extreme position, the third ring 93 is squeezed, and the third ring 93 drives the connecting column 931 and the ring strip 932 to move in the direction of the first ring 91. At this time, the ring strip 932 pushes one end of the corresponding connecting pipe 961 and the suction head 962 to bend, that is, the plurality of suction heads 962 provided on the two air suction components 9 are simultaneously bent towards the center position of the two suction heads 962. At this time, the annular spring 964 is bent simultaneously. The welding head 2 is taken to weld the fiber optic connector, and the plurality of suction heads 962 bent towards each other perform the air extraction work to draw away the heat generated by the welding in the first time, avoiding the influence of the overheated welding environment on the optical fiber of the fiber optic connector.

[0039] Working principle: When airtight welding of the fiber optic connectors of medical devices is required, first insert the two fiber optic connectors into the corresponding positioning rings 7 and the suction components 9 respectively to preliminarily connect the two fiber optic connectors. At this time, the connection part of the two fiber optic connectors is in the middle position between the two suction components 9. The fiber optic connectors inside are positioned by the positioning rings 7. At this time, without manual operation, the subsequent connection of the fiber optic connectors can be completed by the movement and rotation of the two positioning rings 7. At this time, the two suction components 9 are attached to each other, and the connection position of the fiber optic connectors is between the two suction components 9. Under electric drive, the annular airbag 911 inside the first ring 91 is inflated and expanded, sticking to the outer side of the corresponding fiber optic connector, maintaining a certain airtightness, so that the two suction components 9 cover and wrap the outer side of the connection part of the two fiber optic connectors. When the two fiber optic connectors are driven by the positioning rings 7 to move and rotate to continue the connection, the multiple air guiding structures 96 arranged inside the second ring 92 can perform a pumping function, guiding the gas inside the two suction components 9 and the gas at the connection part of the two fiber optic connectors to the outside together. That is, when the welding head 2 needs to weld the fiber optic connectors, the fiber optic connectors are in a near-vacuum state, which can effectively increase the effect of airtight welding. After the pumping operation and the installation of the two fiber optic connectors are completed, the annular airbag 911 is deflated by pumping. Under electric drive, the two suction components 9 move away from each other, revealing the connection position of the fiber optic connectors. Then, the connection position of the fiber optic connectors is rotated by driving the two positioning rings 7. At this time, 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 fiber optic connectors, better-effect airtight welding is completed. When the two suction components 9 are attached to each other, the annular spring 964 is in a natural state, and the multiple connecting pipes 961 are in a vertical state. When welding is required after the pumping operation for the connection position of the fiber optic connectors is completed, through the telescopic drive of the telescopic cylinder 95, the two suction components 9 move away from each other until the third ring 93 contacts the inner wall of the arc-shaped moving groove 81 and applies pressure to the third ring 93 to move it towards the first ring 91. At this time, the connection position of the fiber optic connectors is revealed, and the two fiber optic connectors can be rotated by driving the two positioning rings 7, which is convenient for the airtight welding of the subsequent welding head 2. When the suction component 9 moves away from each other to the limit 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 towards the first ring 91. At this time, the ring strip 932 pushes one end of the corresponding connecting pipe 961 and the suction head 962 to bend, that is, all the multiple suction heads 962 arranged on the two suction components 9 are bent towards 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. Take the welding head 2 to weld the fiber optic connectors. The multiple suction heads 962 bent towards each other perform a pumping operation to quickly remove the heat generated by welding, avoiding the influence of the overheated welding environment on the optical fiber of the fiber optic connectors.
