Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber ferrule welding, and particularly relates to a welding device for an optical fiber ferrule and a metal tube shell. Background Art

[0002] The optical fiber ferrule includes a connected optical fiber and a ferrule. The side wall of the metal tube shell is provided with a protruding portion, and a through hole penetrates through the center of the protruding portion to communicate with the inside of the metal tube shell. When welding the optical fiber ferrule and the metal tube shell, the ferrule needs to be inserted into the protruding portion, and solder is placed in the gap between the two to form a device to be welded. Then, the welding device is used to heat the part where the solder is placed between the ferrule and the protruding portion. The solder melts to achieve the welded connection between the optical fiber ferrule and the metal tube shell. For the case where optical fiber ferrules need to be welded to both ends of the metal tube shell, the existing welding equipment needs to move the device to be welded after completing the welding of one end, so that the position to be welded at the other end is moved to the welding equipment for welding again.

[0003] The welding state of the optical fiber ferrule and the metal tube shell directly affects the airtightness of the device. During the welding process, moving the device to be welded will increase the risk of damage to the device, thereby affecting the airtightness of the device. Therefore, a welding device that does not need to move the device to be welded during the welding process is required. Summary of the Invention

[0060] The embodiments of the present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0061] Figure 1 Stereoscopic structure diagram of the welding device for the optical fiber tail tube and the metal tube shell according to an embodiment of the present invention, as Figure 1As shown in the figure, the welding device for an optical fiber tail tube and a metal tube shell includes a support frame 1, a lifting assembly 2, a bearing tray 3, a horizontal driving assembly 4, and a welding assembly 5. The lifting assembly 2 is arranged on the support frame 1; the bearing tray 3 is connected to the movable end of the lifting assembly 2 and moves longitudinally back and forth under the drive of the lifting assembly 2; the horizontal driving assembly 4 is erected above the bearing tray 3; the welding assembly 5 is drivingly connected to the horizontal driving assembly 4 and moves back and forth along the extending direction of the bearing tray 3 under the drive of the horizontal driving assembly 4.

[0062] During use, place the metal tube shell with optical fiber tail tubes connected to both ends on the bearing tray 3, start the horizontal driving assembly 4, and make the horizontal driving assembly 4 drive the welding assembly 5 to move to the position where the welding point of the metal tube shell and one of the optical fiber tail tubes is on the same longitudinal straight line. Then start the lifting assembly 2, and make the lifting assembly 2 drive the bearing tray 3 to rise, thereby driving the metal tube shell and the optical fiber tail tubes to rise synchronously. After rising to the set height, stop the lifting assembly 2. Start the welding assembly 5 and perform welding operations on the welding point position of the metal tube shell and one of the optical fiber tail tubes. After the welding operation at one end is completed, start the lifting assembly 2 again, and make the lifting assembly 2 drive the bearing tray 3 to descend, thereby driving the metal tube shell and the optical fiber tail tubes to descend synchronously. After descending to the set height where it will not affect the movement of the welding assembly 5, stop the lifting assembly 2, start the horizontal driving assembly 4 again, and make the horizontal driving assembly 4 drive the welding assembly 5 to move to the position where the welding point of the metal tube shell and the other optical fiber tail tube is on the same longitudinal straight line. Then start the lifting assembly 2 again, and make the lifting assembly 2 drive the bearing tray 3 to rise, thereby driving the metal tube shell and the optical fiber tail tubes to rise synchronously. After rising to the set height, start the welding assembly 5 and perform welding operations on the welding point position of the metal tube shell and the other optical fiber tail tube, thus completing the welding process of the optical fiber tail tubes at both ends of the metal tube shell. Finally, control the lifting assembly 2 to drive the bearing tray 3 to descend, thereby driving the metal tube shell and the optical fiber tail tubes to descend synchronously, and take out the welded device.

[0063] By adopting the welding device for an optical fiber tail tube and a metal tube shell of the present invention, the longitudinal movement of the device to be welded, i.e., the metal tube shell and the optical fiber tail tube, is realized by means of the lifting assembly 2, and the horizontal movement of the welding assembly 5 is realized by means of the horizontal driving assembly 4. Furthermore, the welding assembly 5 can respectively align with the welding points of the opposite ends of the metal tube shell and the two optical fiber tail tubes for welding operations, and the entire welding process does not require moving the device to be welded, reducing the risk of damage to the device and being beneficial to improving the airtightness of the device.

[0064] As Figure 1As shown, in this embodiment, the support frame 1 is set as a gantry support frame, including a horizontal support frame and a vertical support frame that are vertically connected. The horizontal support frame is set as an optical flat plate and is connected to the vertical support frame by bolts. The lifting assembly 2 is arranged on the horizontal support frame to drive the carrying tray 3 to move up and down. The horizontal driving assembly 4 is arranged on the vertical support frame to drive the welding assembly 5 to reciprocate along the length extension direction of the vertical support frame. Both the horizontal driving assembly 4 and the welding assembly 5 are located above the carrying tray 3 to ensure that the welding assembly 5 can smoothly perform welding operations on the devices to be welded placed on the carrying tray 3. The lifting assembly 2 can be set as any lifting drive structure, and the horizontal driving assembly 4 can also be set as any horizontal drive structure, such as an electric drive structure, a hydraulic drive structure, etc. As long as the lifting drive structure can drive the carrying tray 3 to move up and down, and the horizontal drive structure can drive the welding assembly 5 to move horizontally, and ultimately enable the welding assembly 5 to align with the welding point for welding operations. The welding assembly 5 can also be set as any welding structure composition, as long as it can move with the horizontal driving assembly 4 and can perform welding operations at the welding point of the metal tube shell and the optical fiber tail tube.

[0065] Figure 2 is Figure 1 a schematic diagram of the horizontal driving assembly of the welding device for the optical fiber tail tube and the metal tube shell shown. As Figure 1 and Figure 2 shown, optionally, the horizontal driving assembly 4 includes a first motor 41, a first support plate (not shown), a first screw 42, and a first sliding table 43. The first motor 41 is fixed to the support frame 1; the first support plate is fixed to the support frame 1; the first end of the first screw 42 is drivingly connected to the output shaft of the first motor 41, and the second end of the first screw 42 is rotatably connected to the first support plate; the first sliding table 43 is sleeved on the first screw 42 and is threadedly connected to the first screw 42, and the welding assembly 5 is fixedly connected to the first sliding table 43. This setting simplifies the structural composition of the horizontal driving assembly 4, enables the welding assembly 5 to move stably, and by controlling the start and stop of the first motor 41, the welding assembly 5 can be accurately moved to the welding point position of the device to be welded, realizing precise welding.

[0066] As Figure 1 and Figure 2As shown, in this embodiment, the first motor 41 is a stepper motor, which is fixed to the right side of the center of the vertical bracket of the support frame 1. The first support plate is fixed to the left side of the center of the vertical bracket of the support frame 1. The first slide table 43 is a cuboid as a whole, sleeved on the first screw rod 42 and threadedly connected to the first screw rod 42. The left end of the first screw rod 42 is rotatably connected to the first support plate by means of a bearing, and the right end is fixedly connected to the output shaft of the first motor 41. The welding assembly 5 is fixed to the first slide table 43. When the welding assembly 5 needs to move left and right to approach the welding point, the first motor 41 is started, so that the first motor 41 drives the rotation of its output shaft, and further drives the first screw rod 42 fixedly connected thereto to rotate. The rotation of the first screw rod 42 further drives the first slide table 43 threadedly connected thereto to linearly move along the length direction of the first screw rod 42, and finally drives the welding assembly 5 connected to the first slide table 43 to move left and right. By changing the rotation direction of the output shaft driven by the first motor 41, the linear movement direction of the welding assembly 5 can be adjusted. A magnetic switch can be connected to the circuit where the first motor 41 is located, and the start and stop of the first motor 41 can be controlled by controlling the on and off of the magnetic switch.

[0067] Figure 3 For Figure 1 The schematic diagram of the welding assembly of the welding device for the optical fiber tail tube and the metal tube shell as shown. As Figure 1 And Figure 3 shown, optionally, the welding assembly 5 includes a fixed table 51, a first fixed column 52 and a second fixed column 53 arranged oppositely, two limit columns 54, a spring 55, two metal pads 56, two graphite electrodes 57 and a telescopic structure 58. The fixed table 51 is fixedly connected to the first slide table 43; one end of the first fixed column 52 facing the bearing tray 3 is rotatably connected to the fixed table 51, and the second fixed column 53 is fixedly connected to the fixed table 51; the two limit columns 54 are respectively fixedly connected to one ends of the first fixed column 52 and the second fixed column 53 facing the bearing tray 3; the opposite ends of the spring 55 are respectively connected to the opposite sides of the two limit columns 54; one ends of the two metal pads 56 far from the bearing tray 3 are respectively fixedly connected to the opposite sides of the two limit columns 54, and the two graphite electrodes 57 are respectively fixedly connected to one ends of the two metal pads 56 facing the bearing tray 3, and the two graphite electrodes 57 are arranged oppositely; the fixed end of the telescopic structure 58 is fixedly connected to the fixed table 51, and the movable end of the telescopic structure 58 is drivingly connected to one end of the first fixed column 52 far from the bearing tray 3.

[0068] As Figure 1 And Figure 3As shown in the figure, in this embodiment, the fixed platform 51 is an overall cuboid plate body, whose left end is fixedly connected to the first sliding table 43, and a telescopic structure 58 is fixedly installed at a position slightly to the right of the middle. The first fixed column 52 and the second fixed column 53 are vertically parallel and relatively arranged at the right end of the fixed platform 51. The lower end of the first fixed column 52 is rotationally connected to the fixed platform 51 through a bearing structure, and the upper end is fixedly connected to the movable end of the telescopic structure 58. A counterbore is provided on the fixed platform 51, and the second fixed column 53 is bolted to the fixed platform 51. The lower ends of the first fixed column 52 and the second fixed column 53 are fixedly connected with limit columns 54 respectively. The two limit columns 54 are vertically parallel, and the opposite ends of the spring 55 are fixedly connected to the opposite surfaces of the two limit columns 54 respectively. Metal pads 56 are fixedly installed on the opposite surfaces of the two limit columns 54 away from each other, and the two metal pads 56 are also vertically parallel. A square hole is vertically and horizontally opened at the lower end of each metal pad 56, and a threaded hole is vertically and horizontally opened. One end of the graphite electrode 57 is square and the other end is wedge-shaped, and a threaded hole is also vertically and horizontally opened at the square end. The square end is inserted into the square hole of the metal pad 56, and a bolt is inserted into the corresponding threaded holes of the metal pad 56 and the graphite electrode 57 to realize their connection. The wedge-shaped ends of the two graphite electrodes 57 are relatively arranged, and when in the natural state of not being used, the wedge-shaped ends of the two graphite electrodes 57 abut against each other. When welding operation needs to be carried out, control the movable end of the telescopic structure 58 to extend outwards, driving Figure 3 the first fixed column 52 in Figure 3 to rotate clockwise around its lower end, and then drive the limit columns 54 and the metal pads 56 directly or indirectly connected thereto to rotate in the same direction. During the rotation of the limit column 54, the spring 55 is driven to stretch. During the rotation of the metal pad 56, the graphite electrode 57 connected thereto is driven to move away from the other graphite electrode 57, and a gap is formed between the two graphite electrodes 57. Then start the first motor 41 to drive the first sliding table 43 to move. Driven by the first sliding table 43, the graphite electrode 57 is moved to the welding point position of the metal tube shell and the optical fiber tail tube, and the welding point is located in the gap between the two graphite electrodes 57. At this time, control the movable end of the telescopic structure 58 to contract inwards, driving Figure 3 the first fixed column 52 in Figure 3 and the left limit column 54, the metal pad 56 and the graphite electrode 57 directly or indirectly connected thereto to rotate counterclockwise until the two graphite electrodes 57 clamp the welding point position. In addition, under the elastic stress of the spring 55, the stable clamping of the welding point position can be further ensured. After the graphite electrode 57 stably clamps the welding point of the metal tube shell and the optical fiber tail tube, connect the graphite electrode 57 to an external power supply. Under the action of the current, the graphite electrode 57 is heated and its temperature rises. Then the welding point position of the metal tube shell and the optical fiber tail tube clamped by the graphite electrode 57 also rises in temperature, and the solder pre-placed there melts, completing the welding of the metal tube shell and the optical fiber tail tube. According to the actual application situation, the telescopic structure 58 can be composed of any structure, such as an electric push rod, a telescopic cylinder, etc., as long as it can drive the first fixed column 52 to rotate.

As Figure 4 shown, optionally, the lifting assembly 2 includes a base 21, a second motor 22, a second support plate (not shown), a second screw rod (not shown), a second sliding table 23, a scissor structure 24, and a lifting seat 25.

By means of the stable sliding of the slider in the slideway, the stable sliding of the upper end of the first scissors arm 241 and the lifting seat 25 is achieved. The carrying tray 3 is arranged on the lifting seat 25. When the device to be welded in the carrying tray 3 needs to rise, the second motor 22 is started to drive the rotation of its output shaft, driving the second screw rod connected thereto to rotate in the same direction, driving the second sliding table 23 threadedly connected to the second screw rod to move Figure 4 to the left end in [the component], thereby driving the lower end of the second scissors arm 242 connected to the second sliding table 23 to move in the same direction. During the process of the lower end of the second scissors arm 242 moving to the left, it rises, and at the same time drives the upper end of the first scissors arm 241 to slide to the left relative to the lifting seat 25. The second scissors arm 242 as a whole rises synchronously, and finally drives the lifting seat 25 and the carrying tray 3 thereon to rise synchronously. When the device to be welded in the carrying tray 3 needs to descend, the second motor 22 is started to drive the second screw rod to rotate in the reverse direction, driving the second sliding table 23 to move Figure 4 to the right end in [the component], thereby driving the lower end of the second scissors arm 242 to move synchronously to the right and descend as a whole, and at the same time driving the upper end of the first scissors arm 241 to slide to the right relative to the lifting seat 25. The second scissors arm 242 as a whole descends synchronously, and finally drives the lifting seat 25 and the carrying tray 3 thereon to descend synchronously.

[0074] As Figure 1 shown, in this embodiment, the fixed seat 71 is fixed to the vertical bracket of the support frame 1 by means of an L-shaped bracket 12, as Figure 5 shown, the fixed seat 71 is generally a cuboid, and a receiving groove is formed on the side surface facing the line of sight. The rotating shaft 72 penetrates through the fixed seat 71 in the left-right direction, and both ends are rotatably connected to the fixed seat 71. In order to facilitate the rotation operation of the rotating shaft 72, a handwheel 75 is connected to the right end of the rotating shaft 72. A gear is sleeved within the range of the rotating shaft 72 in the receiving groove and is fixedly connected to the rotating shaft 72. A longitudinally extending rack 73 is meshed with the side of the gear facing the opening of the receiving groove. The side of the rack 73 facing the opening of the receiving groove is fixedly connected to a lifting table 74, and the first camera 6 is connected to the lifting table 74. When the first camera 6 needs to be lifted, rotate the handwheel 75 to drive the rotating shaft 72 and the gear sleeved on the rotating shaft 72 to rotate synchronously. The rotation of the gear drives the rack 73 meshed with it to move upward, thereby driving the lifting table 74 connected to the rack 73 to move upward, and finally driving the first camera 6 connected to the lifting table 74 to move upward. When the first camera 6 needs to be lowered, rotate the handwheel 75 in the reverse direction, driving the rotating shaft 72 and the gear sleeved on the rotating shaft 72 to rotate in the reverse direction synchronously. The reverse rotation of the gear drives the rack 73 meshed with it to move downward, thereby driving the lifting table 74 connected to the rack 73 to move downward, and finally driving the first camera 6 connected to the lifting table 74 to move downward. Figure 5 A locking device is provided on the left side surface of the fixed seat 71 in the [description], which cooperates with the left end of the rotating shaft 72 to limit the rotation of the left end of the rotating shaft 72 when needed, and can effectively ensure that the first camera 6 remains stationary at any position. In order to increase the contact area between the fixed seat 71 and the support frame 1 and improve the connection stability, Figure 5The rear side wall of the middle fixed seat 71 is fixedly connected with a bottom plate 76 with a larger cross-sectional area, and the bottom plate 76 is fixedly connected to the support frame 1. In order to further ensure that the rack 73 can stably move up and down under the drive of the gear, the side of the lifting platform 74 facing the rack 73 is set to a dovetail shape, that is, the width of this part gradually increases in the direction toward the rack 73. Matchingly, the part of the accommodating groove close to the opening is also set to a dovetail groove, and the width of the dovetail groove gradually decreases in the direction toward the opening. The dovetail part of the lifting platform 74 is inserted into the dovetail groove part of the accommodating groove. Because the width of the side of the lifting platform 74 meshing with the rack 73 is greater than the width of the open end of the dovetail groove, the dovetail part of the lifting platform 74 is always inserted into the dovetail groove and can only move synchronously with the up and down movement of the rack 73, and cannot be separated from the dovetail groove, that is, the rack 73 cannot be separated from the accommodating groove.

[0075] Figure 6 for Figure 1 A schematic diagram showing the connection relationship between the first camera of the welding device for optical fiber tail tube and metal tube shell, the R-axis rotating platform and the dovetail groove lifting slide; Figure 7 for Figure 6 The schematic diagram of the R-axis rotating platform is shown in FIG. Figure 1 , Figure 6 and Figure 7 As shown, optionally, the welding device for the optical fiber tail tube and the metal tube shell further includes an R-axis rotating platform 8, the fixed end of the R-axis rotating platform 8 is connected to the lifting platform 74, and the movable end of the R-axis rotating platform 8 is connected to the first camera 6, which is used to drive the first camera 6 to rotate. With the help of the R-axis rotating platform 8, the first camera 6 can be driven to rotate a certain angle, so that the first camera 6 can maintain an appropriate angle with the device to be welded on the carrying tray 3, ensuring a better shooting effect.

[0076] like Figure 7As shown in the figure, in this embodiment, the R-axis rotating platform 8 includes a mounting base 81. A rotating table 82 is rotatably connected to the upper surface of the mounting base 81. Angle scales are marked circumferentially on the rotating table 82. An adjusting micrometer head assembly is provided on the right side of the rotating table 82. The adjusting micrometer head assembly includes a fixed block 86 connected to the mounting base 81. A strip-shaped hole extending vertically is formed through the fixed block 86 in the left-right direction. An adjusting screw 84 is inserted into the strip-shaped hole and is arranged in cooperation with the rotating table 82. A micrometer head 83 is provided above the fixed block 86, and a locking screw 85 is provided below. The micrometer head 83 and the locking screw 85 respectively penetrate into the strip-shaped hole and are arranged in cooperation with the adjusting screw 84. The rotating table 82 can be manually rotated for rough angle adjustment. By screwing the adjusting screw 84 in a certain distance towards the rotating table 82 and rotating the micrometer head 83, the rotating table 82 can be finely adjusted in angle. By screwing the locking screw 85 in or out, the linear movement distance of the micrometer head 83 can be adjusted. The R-axis rotating platform 8 formed by the cooperation of the mounting base 81, the rotating table 82 and the adjusting micrometer head assembly is a mature prior art, and its specific internal structural composition and working principle will not be elaborated here. According to the actual application situation, a rotating platform with other structural forms can also be set as long as it can drive the first camera 6 to rotate.

[0077] Figure 8 For Figure 1 Schematic diagram of the connection relationship between the second camera of the welding device for the optical fiber tail tube and the metal tube shell and the two-dimensional adjustment frame. As Figure 1 And Figure 8 As shown in the figure, optionally, the welding device for the optical fiber tail tube and the metal tube shell further includes a two-dimensional adjustment frame 9 and a second camera 10. The two-dimensional adjustment frame 9 is fixedly connected to the support frame 1 and is located below the carrier tray 3; the second camera 10 is connected to the two-dimensional adjustment frame 9 through an optical support 11. With this setting, the welding process of the metal tube shell and the optical fiber tail tube can be photographed by the second camera 10 from bottom to top.

[0078] As Figure 1 As shown in the figure, in this embodiment, a total of two second cameras 10 are provided, which are respectively arranged at the lower left corner and the upper right corner of the horizontal support part of the support frame 1. The angle of the second camera 10 can be adjusted by means of the two-dimensional adjustment frame 9. According to the actual application situation, the specific setting position and the number of the second cameras 10 can both be adjusted.

[0079] Figure 9 For Figure 1 Schematic diagram of the carrier tray of the welding device for the optical fiber tail tube and the metal tube shell. As Figure 1 And Figure 9As shown, optionally, the carrier tray 3 includes a package tray 31 and two optical fiber trays 32. A card slot 33 is formed in the package tray 31; the two optical fiber trays 32 are respectively fixedly connected to opposite ends of the package tray 31. With this arrangement, both the metal package and the optical fibers in the optical fiber tails have dedicated positions, without interfering with each other, and the card slot 33 can correspond and match with the protrusion on the metal package, enabling the metal package to be limited, that is, limiting the entire device to be welded, facilitating subsequent welding operations.

[0080] As Figure 1 and Figure 9 shown, in this embodiment, a card slot 33 is provided at the center position of the package tray 31 for fixing the metal package. The left and right ends of the package tray 31 are respectively connected to the optical fiber trays 32. The optical fiber trays 32 are shaped like fan blades. Since the winding directions of the optical fibers at both ends are opposite, the two optical fiber trays 32 are asymmetrically connected to both sides of the package tray 31. The optical fiber trays 32 are provided with a protruding structure at the outer edge. This protruding structure design can ensure that the optical fibers are in a safe position during the welding process and will not affect the welding.

[0081] Optionally, an avoidance hole 34 is provided at the connection between the package tray 31 and the optical fiber tray 32. The connection between the package tray 31 and the optical fiber tray 32 approximately corresponds to the welding point position of the metal package and the optical fiber tail. By providing the avoidance hole 34 here, the second camera 10 can extend into the avoidance hole 34, so as to be able to monitor the welding process of the metal package and the optical fiber tail at a closer distance.

[0082] As Figure 9 shown, in this embodiment, an avoidance hole 34 is opened on the lower side of the connection position between the package tray 31 and the left optical fiber tray 32, and an avoidance hole 34 is opened on the upper side of the connection position between the package tray 31 and the right optical fiber tray 32. Figure 1 In, the second cameras 10 are respectively arranged at the lower left corner and the upper right corner of the horizontal bracket of the support frame 1. The two second cameras 10 respectively extend into the two avoidance holes 34 opened at the lower left and upper right of the package tray 31.
