Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and in particular to an integrated device for laser welding and cutting of the tailstock of an optical fiber connector. Background Technology

[0002] In the manufacturing of optical fiber communication devices, such as Figure 11 As shown, the tailstock of the fiber optic connector is welded from the retaining ring and the tailstock tube. The common practice in the industry is that the cutting of the tailstock tube, the welding with the retaining ring, and the subsequent grinding of the weld are usually completed sequentially in multiple independent stations or on multiple devices. For example, the tailstock tube is first cut to a fixed length using a special cutting device, and then the cut tailstock tube and the retaining ring are transferred to the welding station for manual positioning and welding. After the welding is completed, it is transferred to the grinding station to process the weld. This step-by-step processing method introduces some problems in some continuous production conditions. Since the workpiece needs to be clamped and transferred multiple times between different equipment, it increases the production cycle time. On the other hand, repeated clamping and positioning may affect the concentricity of the final weld due to cumulative errors or operational differences. In addition, in the welding process, if the fixing ring and the tail shank tube are only positioned by simple clamps, slight displacement may occur when heated or subjected to uneven force, resulting in fluctuations in weld quality. For annular joints that require 360° uniform welding, traditional equipment has limitations in achieving stable and uniform rotation of the workpiece, which may lead to insufficient energy input or insufficient grinding in local areas of the weld, affecting the connection strength and appearance consistency. To address the aforementioned issues, this invention proposes an integrated device for laser welding and cutting of the tailstock of fiber optic connectors. Summary of the Invention

[0003] This invention provides an integrated device for laser welding and cutting of the tailstock of fiber optic connectors, which solves the problems of low efficiency, difficulty in ensuring concentricity, and fluctuation in weld quality in traditional step-by-step processing.

[0004] This invention provides the following technical solution: An integrated device for laser welding and cutting of fiber optic connector tailstocks includes a base, a bracket fixedly mounted on the top of the base, and a first support plate and a second support plate fixedly mounted on the top of the bracket, and further includes: A cutting component, mounted on top of the first and second support plates, is used to cut the tail tube to a standard length; A support mechanism is installed on one side of the first support plate. Multiple docking shafts are equally spaced on the support mechanism. The docking shafts are used to connect the fixing ring and the tail tube and keep them concentric. A drive component, mounted on one side of the second support plate, is used to press and drive the tail tube to rotate; A processing component is installed on one side of the first support plate and is used to weld the connection between the fixing ring and the tail tube, and to grind the weld. The tail tube and the fixing ring are sleeved on the docking shaft, and then sequentially undergo cutting by the cutting component, rotation by the supporting mechanism, rotation drive by the driving component, and welding and grinding by the processing component to complete the integrated processing.

[0005] In one possible design, the cutting component includes a mounting bracket fixedly mounted on the top of the first support plate and the second support plate. The inner wall of the mounting bracket is provided with a slide rail, and a support plate is slidably connected to the slide rail. A second drive motor is fixedly mounted on the bottom of the support plate, and a cutting disc is fixedly mounted on the output shaft of the second drive motor. A first electric push rod is fixedly mounted on the top of the mounting bracket, and the bottom end of the first electric push rod is fixedly connected to the top of the support plate. The first electric push rod is used to drive the cutting disc to rise and fall to cut the tail tube.

[0006] In one possible design, a first drive motor is also fixedly installed at the bottom of the tray, and a friction roller is fixedly installed on the output shaft of the first drive motor. The friction roller is used to press and drive the tail tube to rotate during cutting, so that the cutting disc can perform circumferential cutting on the tail tube.

[0007] In one possible design, the support mechanism includes a stepper motor fixedly mounted on one side of the first support plate, and a protective cover fixedly mounted on the side of the first support plate near the second support plate. The output shaft of the stepper motor extends into the protective cover and is fixedly mounted with a drive gear. A gear ring meshing with the drive gear is rotatably sleeved on the mounting rod. A connecting ring is fixedly mounted on one side of the gear ring. A support frame located outside the protective cover is fixedly sleeved on the connecting ring. A plurality of docking shafts are rotatably connected at equal intervals to one side of the support frame. A retaining plate for supporting the fixing ring is fixedly sleeved on the docking shaft.

[0008] In one possible design, the drive component includes a fixed box fixedly mounted on one side of the second support plate, a support assembly installed inside the fixed box, a rotating assembly mounted on the support assembly, a first docking cover and a second docking cover connected to one side of the rotating assembly, and a second electric push rod fixedly mounted on one side of the fixed box. The output shaft of the second electric push rod is connected to the support assembly for driving the first docking cover or the second docking cover to press against the tail tube.

[0009] In one possible design, the support assembly includes two support shafts symmetrically fixedly installed inside the fixed box, with the same fixed plate slidably sleeved on the two support shafts, the rotating assembly mounted on the fixed plate, and the output shaft of the second electric push rod fixedly connected to one side of the fixed plate.

[0010] In one possible design, the rotating assembly includes a third drive motor fixedly mounted on one side of the fixed plate. The output shaft of the third drive motor passes through the fixed plate and is fixedly mounted on a first mounting shaft. One end of the first mounting shaft is fixedly connected to the first docking cover. A second mounting shaft is also rotatably connected to the fixed plate. One end of the second mounting shaft is fixedly connected to the second docking cover. The first mounting shaft and the second mounting shaft are connected by a transmission component. The first mounting shaft is driven to rotate by the third drive motor, thereby causing the first docking cover and the pressed tail tube to rotate, so as to cooperate with the processing component for welding.

[0011] In one possible design, the transmission component includes two synchronous pulleys, which are respectively fixedly sleeved on the first mounting shaft and the second mounting shaft. The same synchronous belt is driven on the two synchronous pulleys, so that the third drive motor can simultaneously drive the second docking cover to rotate in order to grind the weld.

[0012] In one possible design, the processing component includes two slide rods fixedly mounted on the side of the first support plate near the second support plate, with the same adjusting plate slidably sleeved on the two slide rods. A third electric push rod is fixedly mounted on the side of the first support plate away from the second support plate, and the output shaft of the third electric push rod is fixedly connected to one side of the adjusting plate. A laser welding machine is fixedly mounted on the top of the other side of the adjusting plate, and a laser welding head for welding is fixedly mounted on the output end of the laser welding machine.

[0013] In one possible design, a fourth drive motor is fixedly installed on the bottom side of one side of the adjustment plate, and a grinding wheel head for grinding the weld is fixedly installed on the output shaft of the fourth drive motor. After welding is completed, the third electric push rod drives the adjustment plate to move, so that the grinding wheel head is aligned with the weld. At the same time, the drive component drives the tail tube to rotate to fully grind the weld.

[0014] In this invention, when processing the tailstock of the fiber optic connector, the fixing ring and tailstock tube to be welded are first fitted onto the corresponding docking shaft on the support mechanism through the feeding hole. The fixing ring is supported and limited by the baffle on the docking shaft to keep the two axes aligned. Then, the first electric push rod in the cutting component is activated to move the support plate downward, causing the cutting disc and friction roller to move downward. At the same time, the second drive motor is activated to drive the cutting disc to rotate at high speed to cut the tailstock tube and adjust its length to the standard length. During this process, the first drive motor drives the friction roller to rotate, driving the tailstock tube to rotate under the action of static friction, which facilitates the cutting disc to cut the entire length. After the cutting is completed, the stepper motor is activated to drive the drive gear to rotate. Through meshing with the gear ring, the connecting ring is driven to rotate, thereby driving the fixing ring and tailstock tube on the support frame and docking shaft to move towards the area where the drive component and processing component are located. When they move to the position corresponding to the first docking cover in the drive component, the second electric push rod is activated to drive the fixing plate to move laterally, so that the first docking cover is fitted onto the corresponding docking shaft and presses the tailstock tube. Then, the third drive rod is activated. The motor drives the first mounting shaft to rotate, causing the first docking cover to rotate along with the tailstock tube and the fixing ring. Simultaneously, the third electric push rod is activated, moving the adjusting plate to align the laser welding head with the joint between the fixing ring and the tailstock tube. The laser welding machine is then activated, and welding is performed through the laser welding head. The rotational force of the first docking cover achieves complete welding of the joint. After welding, the second electric push rod is activated, causing the first docking cover to reverse and reset. The stepper motor is then activated again, moving the fixing ring and tailstock tube to the docking position with the second docking cover. The second electric push rod... The second mating cover is pressed against the tail tube. Under the transmission action of the two synchronous pulleys and synchronous belt in the transmission component, the third drive motor drives the second mounting shaft to rotate, causing the second mating cover to drive the tail tube and the fixing ring to rotate. At the same time, the third electric push rod is started to move the grinding wheel head to the weld. The fourth drive motor is started to drive the grinding wheel head to rotate, and the weld is fully ground. After the fiber optic connector tail tube is processed, the finished fiber optic connector tail tube can be pulled out from the mating shaft by moving the fiber optic connector tail tube to the position corresponding to the feeding hole.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0016] Beneficial effects: 1. This technical solution integrates the three core processes of cutting, welding, and weld grinding, eliminating the need to transfer workpieces between multiple devices, reducing the time spent on process connections, shortening the production cycle, solving the problem of low efficiency in traditional step-by-step processing, and adapting to the needs of large-scale production of fiber optic connector tailstocks. 2. The fixed ring and the tail shank tube are supported by the docking shaft of the support mechanism to ensure that the concentricity of the two is consistent during welding and to avoid positional deviation. During cutting, the friction roller is used to limit the movement and drive the tail shank tube to rotate, so as to achieve full cutting. During welding and grinding, the workpiece is driven to rotate by the drive component to ensure uniform weld and thorough grinding, effectively reducing the product scrap rate caused by processing deviation. 3. All components work together in a highly automated manner. For example, during cutting, the electric push rod drives the cutting disc to rise and fall, and the drive motor drives the cutting disc and friction roller to rotate. During welding and grinding, the electric push rod adjusts the position of the processing components and the drive components drive the workpiece to rotate. There is no need for frequent manual adjustment of the workpiece position and processing angle, which reduces the intensity of manual operation and skill requirements.

[0017] 4. A stable support is formed through the bracket, first support plate, second support plate, reinforcing rod and other structures. The mounting rod, support shaft and other components provide precise guidance and support for each moving component, reducing shaking and wear during equipment operation. The protective cover protects the internal transmission structure to prevent dust and debris from affecting the operation of the components, thereby improving the stability and service life of the equipment. 5. The support mechanism is equipped with multiple equally spaced docking shafts, which can simultaneously carry multiple workpieces for cyclic processing, thereby increasing the processing throughput. The cutting, welding, and grinding components can all be adjusted in position through structures such as electric push rods, adapting to the processing of different specifications of fiber optic connector tail shanks and expanding the applicability of the equipment.

[0018] This invention integrates cutting, welding, and grinding. During cutting, the tail shank tube is driven to rotate to achieve full cutting. Welding is carried out with the help of the rotating docking cover. Grinding is done in the same way. Moreover, it eliminates the need for multiple clamping and handling of workpieces, reducing damage, improving cutting accuracy, welding quality and grinding effect, reducing process complexity and time cost, and meeting the needs of large-scale production.

For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0025] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention.

[0026] In one embodiment: Refer to Figure 1-11An integrated device includes a base 1. A bracket 2 is fixedly installed on the top of the base 1 by welding. A first support plate 3 and a second support plate 4 are respectively fixed to the top of the bracket 2 by welding. Both the first support plate 3 and the second support plate 4 are 15mm thick Q235 round steel plates, arranged parallel to each other with a spacing of about 50mm. A feeding hole 24 is opened on the first support plate 3. An installation rod 5 is welded to the center of one side of the first support plate 3. The installation rod 5 is a 30mm diameter 45# steel round rod, one end of which is welded and fixed to one side of the second support plate 4. In order to enhance the structural rigidity, four reinforcing rods 6 are also installed on one side of the first support plate 3. The four reinforcing rods 6 are rectangularly distributed, all of which are 20mm diameter round rods, one end of which is welded to one side of the second support plate 4.

[0027] The integrated device also includes a cutting component, a support mechanism, a drive component, and a processing component.

[0028] like Figure 7 As shown, the cutting components are respectively installed on the top of the first support plate 3 and the top of the second support plate 4. Specifically, the cutting components include a mounting bracket 16, which is fixed to the top of the first support plate 3 and the second support plate 4 by bolts. Slide rails 17 are welded and fixed to the inner walls of both sides of the mounting bracket 16, and the same support plate 18 is slidably connected to the two slide rails 17. A second drive motor 22 is fixedly installed on one side of the bottom of the support plate 18 via a motor mounting bracket. A cutting disc 23, a diamond cutting disc with an outer diameter of 150 mm and a thickness of 1.5 mm, is fixedly installed on the output shaft of the second drive motor 22 via a key connection. The cutting disc 23 is a diamond cutting disc with an outer diameter of 150 mm and a thickness of 1.5 mm. A first electric push rod 19 is fixedly installed on the top of the mounting bracket 16 via a mounting seat. The push rod 19 has a stroke of 200 mm, and its bottom end extends into the mounting bracket 16 and is fixedly connected to the top of the support plate 18 via a connecting block. On the other side of the bottom of the tray 18, a first drive motor 20 is fixedly mounted by a motor mounting bracket. A friction roller 21 is fixedly mounted on the output shaft of the first drive motor 20. The friction roller 21 is a polyurethane rubber wheel with an outer diameter of 60mm and a Shore hardness of 70A.

[0029] like Figure 4-6As shown, the support mechanism is installed on one side of the first support plate 3. Specifically, the support mechanism includes a stepper motor 7 fixedly installed on one side of the first support plate 3 via a motor mount, and a protective cover 10 fixedly installed on the side of the first support plate 3 near the second support plate 4 via bolts. The mounting rod 5 passes through the protective cover 10. The output shaft of the stepper motor 7 extends into the protective cover 10 via a coupling and is fixedly mounted with a drive gear 8, which has a module of 2 and 30 teeth. A gear ring 9 located inside the protective cover 10 is rotatably sleeved on the mounting rod 5 via a bearing. The gear ring 9 has a module of 2 and 120 teeth. The drive gear 8 meshes with the gear ring 9. A connecting ring 11 is welded and fixed to one side of the gear ring 9. One side of the connecting ring 11 passes through one inner wall of the protective cover 10 and extends to the outside of the protective cover 10. The connecting ring 11 is rotatably connected to one inner wall of the protective cover 10 via a sealed bearing. A support frame 12, located outside the protective cover 10, is fixedly sleeved on the connecting ring 11. The support frame 12 is a stainless steel ring with an outer diameter of 400 mm. Five mating shafts 13 are rotatably connected to one side of the support frame 12 at equal intervals via deep groove ball bearings. The mating shafts 13 are hard chrome shafts with a diameter of 8 mm and a tolerance of h7. A retaining plate 14, with an outer diameter of 20 mm and a thickness of 5 mm, is fixedly sleeved on them to axially limit the movement of the fixing ring 15.

[0030] like Figure 8-9As shown, the drive component is installed on one side of the second support plate 4. Specifically, the drive component includes a fixed box 25 bolted to one side of the second support plate 4. A support assembly is installed inside the fixed box 25, and a rotating assembly is mounted on the support assembly. The support assembly includes two support shafts 26 symmetrically welded and fixed inside the fixed box 25. The two support shafts 26 are optical shafts with a diameter of 25mm, and the same fixed plate 27 is slidably sleeved on them.

For example, when the outer diameter of the tailstock tube 151 is 6 mm, the inner diameter of the liner can be designed to be 6.2 mm. The first mounting shaft 29 and the second mounting shaft 31 are connected by the same transmission component. The transmission component includes two synchronous pulleys 33, both of which are located inside the fixed box 25 and are respectively fixedly sleeved on the first mounting shaft 29 and the second mounting shaft 31 by set screws. The two synchronous pulleys 33 are driven by the same synchronous belt 34.

[0031] This application can be used in the field of optical fiber communication technology, or in other fields applicable to this application.

[0032] In another embodiment: Reference Figure 3 and Figure 10Based on the above embodiments, an improved version is proposed: an integrated device for laser welding and cutting of fiber optic connector tailstocks, applied to the field of fiber optic communication technology. The structure of this embodiment is basically the same as the aforementioned embodiments, except that the processing component is installed on one side of the first support plate 3. Specifically, the processing component includes two sliding rods 36 bolted to the side of the first support plate 3 near the second support plate 4. The two sliding rods 36 are linear optical axes with a diameter of 20mm, and the same adjusting plate 37 is slidably mounted on them. A third electric push rod 38 is fixedly installed on the side of the first support plate 3 away from the second support plate 4. The push rod stroke of the third electric push rod 38 is 50mm, and its output shaft passes through the first support plate 3 and is fixedly connected to one side of the adjusting plate 37 via a connector. A laser welding machine 39 is fixedly installed on the top of the other side of the adjusting plate 37 via a bracket. The output end of the laser welding machine 39 passes through the adjusting plate 37 and a laser welding head 40 is fixedly installed via a quick-change connector. A fourth drive motor 41 is fixedly installed on one side bottom of the adjustment plate 37 via a motor mount. The output shaft of the fourth drive motor 41 passes through the adjustment plate 37 and is fixedly installed with a grinding wheel 42 via a chuck. The grinding wheel 42 is a cup-shaped grinding wheel with a grit size of 180 mesh or 240 mesh.

[0033] In this embodiment, the first docking cover 30 and the second docking cover 32 are arranged in upper and lower positions respectively, based on the actual processing sequence. If the upper and lower separation structure is not adopted, and the welding and grinding stations are arranged on the same horizontal plane, the support mechanism will need a larger rotation angle to switch stations, which will increase the radial space occupied by the device. In the case of a compact workshop layout, this design can make more reasonable use of the vertical space between the first support plate 3 and the second support plate 4.

[0034] When processing the tailstock of the fiber optic connector, the operator first places the retaining ring 15 and a long tailstock tube 151 to be processed onto the docking shaft 13 at the loading station through the feeding hole 24, with the retaining ring 15 abutting against the retaining plate 14. The first electric push rod 19 is activated, causing the support plate 18 to move downwards along the slide rail 17, causing the cutting disc 23 and friction roller 21 to move downwards synchronously. When the friction roller 21 contacts the outer surface of the tailstock tube 151 and generates a clamping force of approximately 10N, the cutting disc 23 also reaches the predetermined cutting position. The second drive motor 22 is activated to rotate the cutting disc 23, and simultaneously the first drive motor 20 is activated to rotate the friction roller 21. Under the action of static friction between the friction roller 21 and the tailstock tube 151, the tailstock tube 151 is driven to rotate slowly, and the cutting disc 23 completes the circumferential cutting of the tailstock tube 151.

[0035] After cutting, the first electric push rod 19 moves the support plate 18 upward and resets it. The stepper motor 7 is started, driving the drive gear 8 to rotate, which in turn drives the meshing gear ring 9 and connecting ring 11 to rotate 120 degrees. The connecting ring 11 drives the support frame 12 and the six docking shafts 13 to rotate together, so that the cut workpiece is transferred to the welding station and coaxially corresponds with the first docking cover 30. At this time, the second electric push rod 35 is started, pushing the fixing plate 27 to move along the support shaft 26 towards the workpiece, so that the inner liner of the first docking cover 30 is fitted onto the end of the tail tube 151 and a certain clamping force is applied. Then, the third drive motor 28 is started, driving the first docking cover 30 to rotate at a constant speed of 5 rpm through the first mounting shaft 29, thereby driving the tail tube 151 and the fixing ring 15 to rotate synchronously on the docking shaft 13. Simultaneously, the third electric push rod 38 is activated, pushing the adjusting plate 37 to move along the slide rod 36, adjusting the focus of the laser welding head 40 to align with the joint between the fixing ring 15 and the tailstock tube 151, approximately 2mm from the joint. The laser welding machine 39 is then activated, with an output power of 800W and a pulse frequency of 50Hz, performing continuous 360° welding on the rotating joint. Fumes generated during welding are extracted by the exhaust pipe integrated into the welding head.

[0036] After welding is completed, the laser welding machine 39 is turned off, and the second electric push rod 35 drives the first docking cover 30 to reset and detach from the workpiece. The stepper motor 7 drives the support frame 12 to rotate 120 degrees again, turning the workpiece into the grinding position, coaxially corresponding with the second docking cover 32. The second electric push rod 35 moves again, causing the second docking cover 32 to fit over and press against the end of the tail tube 151. The third drive motor 28 starts again, driving the second mounting shaft 31 and the second docking cover 32 to rotate at the same speed of 5 rpm through the transmission of the synchronous pulley 33 and the synchronous belt 34, driving the workpiece to rotate. At the same time, the third electric push rod 38 moves, moving the grinding wheel head 42 on the adjusting plate 37 to the weld position, maintaining a gap of about 0.5 mm with the weld surface. The fourth drive motor 41 is started, driving the grinding wheel head 42 to rotate at high speed, uniformly grinding the rotating weld, removing weld slag and burrs, and making the weld surface smooth and flat.

[0037] After grinding, all actuators are reset. Stepper motor 7 drives support frame 12 to rotate, moving the finished tail shank tube to the unloading station (which can be the same position as the loading station). The operator removes the finished product through feeding hole 24, completing one processing cycle.
