Description

Technical Field

[0001] The present invention relates to the technical field of laser coupling packaging, in particular to a single-tube pigtail threading machine device. Background Art

[0002] Single-tube lasers are common lasers, primarily consisting of a laser housing, a laser chip, and a fiber pigtail (beam collimator). The laser chip is used to generate laser light, and the fiber pigtail collimates the light beam before emitting it. A connecting ring is also included to connect the fiber pigtail to the laser housing. The coupling package requires accurate positioning of the fiber pigtail and the laser housing before coupling and packaging, ensuring that parameters such as the optical power of the emitted light meet the specified standards. Traditionally, fiber pigtail coupling requires manual labor, which is not only costly and inefficient, but also prone to errors. This compromises the coupling effect and makes it unsuitable for mass automated production.

[0003] The invention patent application with publication number CN115603167A discloses an automatic coupling and packaging device for a beam collimator, including a laser clamp assembly, a beam collimator clamp assembly, an optical power coupling detection assembly, and a glue dispensing and curing assembly. The laser clamp assembly is used to clamp and position the laser tube shell and power it on. The beam collimator clamp assembly is used to clamp the beam collimator and couple it to a preset position of the laser tube shell. The beam collimator is pre-set with a connecting ring, and the connecting ring is used to connect the beam collimator and the laser tube shell. The optical power coupling detection assembly is used to detect the coupling power and confirm the coupling accuracy. The glue dispensing and curing assembly is used to dispense glue and cure the coupling position, and at the same time adjust the position of the connecting ring, which can automatically complete the coupling packaging of the beam collimator and the laser tube shell. In this solution, the beam collimator fixture assembly is a rigid structure. Because the beam collimator and the laser tube housing are high-precision devices and require high-precision coupling, the coaxiality of the beam collimator and the laser tube housing must be very high (the gap is only 10-20μm). Under the premise that the fixture components are all rigid, the pigtail may be damaged due to eccentricity, etc., which can be further improved. Summary of the Invention

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to a locking connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a single-tube pigtail threading machine device, comprising a laser fixture assembly 100, a pigtail fixture assembly 200, a visual coupling detection assembly 300, and a glue curing assembly 400. The laser fixture assembly 100 is used to clamp and position the laser tube housing 501, the pigtail fixture assembly 200 is used to clamp the pigtail 502 and couple it with the laser tube housing 501, the visual coupling detection assembly 300 is used to visually detect the relative position of the pigtail 502 and the tube hole of the laser tube housing 501 to confirm the coupling accuracy, and the glue curing assembly 400 is used to glue and cure the coupling position.

[0040] In this embodiment, the laser fixture assembly 100 includes a laser fixture base 101 and a laser fixture adjustment mechanism 102. The laser fixture adjustment mechanism 102 is used to adjust the azimuth angle, pitch angle, and fore-aft position (X coordinate) of the laser fixture base 101, so that the laser housing 501 is adjusted to a preset posture for coupling. It should be noted that because this embodiment utilizes visual coupling detection assembly 300 to visually detect relative positional relationships and confirm coupling accuracy, the laser housing 501 no longer needs to be powered on or cooled by water cooling channels, further simplifying the structure of the laser fixture assembly 100.

[0041] At the same time Figure 3 As shown, in this embodiment, the pigtail clamp assembly 200 includes a pigtail displacement mechanism 210 and a pigtail clamp mounted on the pigtail displacement mechanism 210. The pigtail displacement mechanism 210 is used to adjust the position of the pigtail clamp, on the one hand, allowing the pigtail 502 to enter the tail hole of the laser housing 501 at a preset position (i.e., the initial position before coupling). On the other hand, the position of the pigtail 502 is adjusted during the coupling process to ensure that its relative position relationship with the tail hole of the laser housing 501 and the coupling accuracy meet the requirements.

[0042] Since the coaxiality requirements between the pigtail 502 and the tail hole of the laser tube shell 501 are very high, and the gap between them is usually only 10-20μm, when the pigtail displacement mechanism 210 drives the pigtail 502 to adjust the coupling, it may cause a significant collision between the pigtail 502 and the tail hole, causing the pigtail 502 to bend or damaged. Based on this, the pigtail clamp in this embodiment includes a clamping portion 220, a rotating portion 230, and a floating connection portion 240. The clamping portion 220 is used to clamp and fix the pigtail 502, the rotating portion 230 is used to drive the clamping portion 220 to rotate and adjust the angle for circumferential glue dispensing, and the floating connection portion 240 is used to connect the clamping portion 220, so that the clamping portion 220 has a certain floating adjustment space to avoid hard collisions between the pigtail 502 and the tail hole.

[0043] Specific as Figure 4 As shown, the floating connection portion 240 includes a floating connection seat 241 and a floating connection block 242. The floating connection seat 241 is provided with a floating adjustment mechanism. The floating connection block 242 is connected to the floating adjustment mechanism. The floating connection block 242 is also elastically connected to the floating connection seat 241, allowing the floating connection block 242 to resiliently return to its original position. Furthermore, the floating connection block 242 is connected to the clamping portion 220. Therefore, when the pigtail displacement mechanism 210 controls the overall displacement of the pigtail fixture, bringing the pigtail 502 into contact with the pigtail hole, the floating adjustment mechanism causes the clamping portion 220 and the floating connection block 242 to displace relative to the floating connection seat 241. Furthermore, the elastic buffering effect prevents hard collisions and bending between the pigtail 502 and the pigtail hole. When the floating adjustment mechanism is adjusted to the correct coupling position (with satisfactory coaxiality), the floating connection block 242 resiliently returns to its initial position, ensuring that it remains in the correct coupling position, allowing subsequent packaging and other processes to proceed.

[0044] In this embodiment, the floating adjustment mechanism includes a first linear mechanism and a second linear mechanism, which are arranged orthogonally. Specifically, initially (after the rotating unit 230 can rotate), the first linear mechanism is arranged along the Y direction, and the second linear mechanism is arranged along the Z direction. The floating connecting block 242 is connected to the first linear mechanism, which in turn is connected to the second linear mechanism. Therefore, the floating connecting block 242 has two degrees of freedom for adjustment, allowing for free adjustment within the YZ plane. Since the pigtail 502 and the laser housing 501 are both arranged along the X direction, sufficient buffer adjustment can be achieved.

[0045] In this embodiment, the first linear mechanism includes a first guide rail 243 and a first slider 244 slidably disposed on the first guide rail 243. The second linear mechanism includes a second guide rail 245 and a second slider 246 slidably disposed on the second guide rail 245. The floating connection block 242 is connected to the first slider 244, the first guide rail 243 is connected to the second slider 246, and the second guide rail 245 is connected to the floating connection seat 241. The first slider 244 and the second slider 246 are able to slide freely relative to the first guide rail 243 and the second guide rail 245, respectively. Their reaction force is provided by elastic restoring force, allowing the pigtail 502 to fully perform floating adjustment, buffering, and elastic reset.

[0046] Furthermore, in this embodiment, the floating connection base 241 defines a mounting slot, within which the floating adjustment mechanism is disposed. A second guide rail 245 is secured to the bottom of the mounting slot, and other components are disposed in a corresponding manner. The first end of the floating connection block 242 is positioned within the mounting slot and connected to the first slider 244. Furthermore, an elastic member, specifically a spring pin 247, is disposed on the inner sidewall of the mounting slot. One end of the spring pin 247 is positioned within a mounting hole 248 in the inner sidewall of the mounting slot, while the other end contacts the outer sidewall of the floating connection block 242.

[0047] It should be noted that in this embodiment, four groups of mounting holes 248 and spring pins 247 are provided, with one group of spring pins 247 provided at two positions along the Y direction and two positions along the Z direction respectively, so that the floating connecting block 242 can be fully elastically buffered and elastically reset along the Y direction and the Z direction.

[0048] In this embodiment, the clamping portion 220 includes a clamping seat 221, on which a fixed clamping arm 222 and a movable clamping arm 223 are disposed relative to each other. The fixed clamping arm 222 is fixedly connected to the clamping seat 221, while the movable clamping arm 223 is movably connected to the clamping seat 221. Furthermore, a clamping control unit is also disposed on the clamping seat 221. In this embodiment, a control cylinder 224 is employed, the piston rod end of which is connected to the movable clamping arm 223. This control unit can drive the movable clamping arm 223 to retract or expand relative to the fixed clamping arm 222, thereby clamping or releasing the pigtail 502.

[0049] It should be noted that a V-shaped groove is provided at the end of the fixed clamping arm 222 , and the cylindrical pigtail 502 is stably limited by the V-shaped groove to ensure stable clamping of the pigtail 502 .

[0050] At the same time Figure 5-Figure 6 As shown, in this embodiment, the visual coupling detection assembly 300 includes a first visual detection camera 301, a second visual detection camera 302, and a third visual detection camera 303. The three visual detection cameras perform relative position detection from multiple angles to confirm the coupling accuracy. Specifically, the first visual detection camera 301 is used to detect the relative position of the pigtail 502 and the tube hole of the laser tube housing 501 in the Y direction, and the second visual detection camera 302 is used to detect the relative position of the pigtail 502 and the tube hole of the laser tube housing 501 in the Z direction. At this time, the relative position accuracy of the pigtail 502 and the tube hole of the laser tube housing 501 in the YZ plane can be confirmed. The third visual detection camera 303 then detects the relative position of the pigtail 502 and the tube hole of the laser tube housing 501 in the XZ plane obliquely, confirming the relative position accuracy of the pigtail 502 and the tube hole of the laser tube housing 501 in the X direction. Thus, the coupling accuracy is confirmed in all directions for subsequent packaging.

[0051] It should be noted that the focal lengths of the first and second visual inspection cameras 301, 302, and so on are fixed. During actual visual inspection, the consistency of the components themselves is not ideal, causing the projection of the pipe hole or the edge of the fiber pigtail 502 to appear different when viewed visually (the edge image is the clearest only when it is exactly in focus). This leads to certain errors in visual positioning. Furthermore, the diameter of the pipe hole and the fiber pigtail 502 are inconsistent, making it impossible to simultaneously position the pipe hole and the fiber pigtail 502 at the camera's focal length. This results in discrepancies in recognition and inaccurate positioning.

[0052] Based on this, this embodiment adds a one-dimensional focus adjustment mechanism in the focal length direction of some cameras, further improving positioning accuracy by combining focus measurement and edge positioning. The first visual inspection camera 301 and the second visual inspection camera 302 are connected to the first focus adjustment mechanism 304 and the second focus adjustment mechanism 305, respectively, to adjust the position of the first visual inspection camera 301 and the second visual inspection camera 302, that is, to adjust the focus position.

[0053] It should be noted that to facilitate the overall layout of the device and reduce its lateral dimensions, in this embodiment, the first visual inspection camera 301 and the first focal length adjustment mechanism 304 are arranged along the X-direction. A reflector assembly 306 is also provided to reflect the optical path of the first visual inspection camera 301 90 degrees in the Y-direction to align the coupling position between the pigtail 502 and the pigtail hole. Furthermore, the reflector assembly 306 includes a reflector adjustment mechanism that adjusts the Y-direction position of the reflector to maintain a suitable optical path reflection position.

[0054] The second visual inspection camera 302 and the second focus adjustment mechanism 305 are arranged along the Z direction, located directly above the laser tube housing 501 and downwardly aligned with the coupling position between the pigtail 502 and the pigtail hole.

[0055] Please refer again Figure 6 In this embodiment, the dispensing and curing assembly 400 includes a dispensing and curing mounting seat 401, which is connected to a dispensing and curing displacement mechanism 402. The dispensing and curing displacement mechanism 402 is used to drive the dispensing and curing mounting seat 401 to move horizontally, and has the degree of freedom of translation in the X direction, the Y direction, and the Z direction or the oblique direction. The dispensing head 403 and the UV curing lamp 404 are both connected to the dispensing and curing displacement mechanism 402. At the same time, Figure 7 As shown, as a further improvement, in this embodiment, multiple dispensing heads 403 are provided and arranged side by side in a straight line, so that glue can be dispensed in an array during dispensing, and the glue layer area of the pigtail 502 can be covered at one time, thereby improving efficiency, and enhancing the uniformity of glue dispensing in the glue layer area, simplifying the steps of multiple circumferential dispensing.

[0056] Based on the same inventive concept, this embodiment also provides a method for threading a single-tube pigtail, comprising the following steps:

[0057] S1 , fix the laser tube shell 501 at a preset position of the laser fixture assembly 100 , place the pigtail 502 on the clamping portion 220 of the pigtail fixture assembly 200 and clamp it.

[0058] S2, the pigtail 502 moves under the drive of the pigtail clamp assembly 200 until the pigtail 502 is at a preset position of the tube hole of the laser tube housing 501 and is preliminarily coupled and positioned.

[0059] S3, multiple visual detection cameras of the visual coupling detection component 300 detect the relative position of the pigtail 502 and the tube hole of the laser tube shell 501 from multiple directions, confirm the coupling accuracy of the pigtail 502, and determine the adjustment direction.

[0060] When adjustment is required, the pigtail displacement mechanism 210 drives the pigtail 502 to adjust. At this time, the floating connection part 240 acts to float and buffer the pigtail 502. After final adjustment, the floating connection part 240 elastically resets and the coupling accuracy of the pigtail 502 meets the requirements.

[0061] S4, the glue dispensing and curing assembly 400 moves to the glue dispensing position to dispense glue, and at the same time, the pigtail 502 rotates circumferentially under the drive of the pigtail clamp assembly 200, so that the glue dispensing position is evenly coated with glue.

[0062] S5, irradiate the dispensing position for a preset time to perform UV curing to complete the coupling packaging of the device.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
