Description

Technical Field

[0001] This application relates to the field of substrate coating separation technology, and in particular to a fixing mechanism and a laser device. Background Technology

[0002] When manufacturing passive optical devices such as fiber optic couplers, the requirements for removing the fiber coating are very stringent, requiring that the fiber be stripped without causing any damage.

[0003] In related technologies, a laser beam of a certain energy and frequency is used to irradiate the coating on the optical fiber, causing the coating to expand and crack due to heat. The cracked coating is then wiped clean to remove the optical fiber. However, after irradiating the optical fiber, the laser beam continues to propagate and strikes a support platform located below the optical fiber. The optical fiber bundle is reflected by the support platform, and the propagation direction of the reflected optical fiber bundle is uncertain. This results in uneven impact on the optical fiber, making it prone to damage. Utility Model Content

[0007] The beneficial effects of the fixing mechanism provided in the first aspect of this application are as follows: the two fixing components clamp the workpiece to be processed, so that the workpiece to be processed is suspended in the suspended position. When the laser irradiates the workpiece to be processed, the reflective inclined surface can reflect the laser. Since the reflective inclined surface is inclined towards the suspended position, the reflective inclined surface can reflect the laser away from the suspended position, so as to prevent the laser from being reflected onto the workpiece to be processed located in the suspended position, thereby preventing the workpiece to be processed from being subjected to uneven impact, and preventing damage to the workpiece to be processed.

[0008] In some embodiments, two reflective ramps are provided, and the two reflective ramps intersect to form a sharp angle protruding toward the suspended position.

[0009] In some embodiments, the intersection line of the two reflective bevels is parallel to the spacing direction of the two fixing components.

[0010] In some embodiments, the fixing component includes a carrier and a retaining member, the carrier being disposed on the support platform and having a bearing surface facing away from the support platform, and the retaining member being connected to the carrier and facing the bearing surface.

[0011] In some embodiments, the carrier has a carrier groove that extends along the interval between the two fixing components, and the opening of the carrier groove is located on the carrier surface.

[0012] In some embodiments, the holding member has a first end and a second end disposed opposite to each other, the first end being rotatably connected to the carrier and the second end being detachably connected to the carrier.

[0013] In some embodiments, the holding member includes a holding portion and an elastic portion, the holding portion being connected to the bearing member, and the elastic portion being disposed on the side of the holding portion facing the bearing surface.

[0014] In some embodiments, the support platform includes a guide rail, the fixing component is slidably disposed on the guide rail, and the fixing component has a locking element capable of clamping the guide rail.

[0015] In some embodiments, the locking member includes a first clamping member and a second clamping member, the second clamping member and the first clamping member being located on opposite sides of the guide rail, the first clamping member being in rolling contact with the guide rail, and the second clamping member being movable relative to the first clamping member to change the distance between the second clamping member and the first clamping member.

[0016] To achieve the above objectives, the technical solution adopted in the second aspect of this application is: a laser device, including the fixing mechanism described in the first aspect of the embodiment.

[0017] The beneficial effect of the laser device provided in the second aspect of this application is that by applying the above-mentioned fixing mechanism to the laser device, the laser device prevents the workpiece from being subjected to uneven impact when cleaning the coating on the workpiece, so as to prevent damage to the workpiece.

[0027] When manufacturing passive optical devices such as fiber optic couplers, the requirements for removing the fiber coating are very stringent, requiring that the fiber be stripped without causing any damage.

[0028] In related technologies, a laser beam of a certain energy and frequency is used to irradiate the coating on the optical fiber, causing the coating to expand and crack due to heat. The cracked coating is then wiped clean to remove the optical fiber. However, after irradiating the optical fiber, the laser beam continues to propagate and strikes a support platform located below the optical fiber. The optical fiber bundle is reflected by the support platform, and the propagation direction of the reflected optical fiber bundle is uncertain. This results in uneven impact on the optical fiber, making it prone to damage.

[0029] In view of the above problems, this application provides a fixing mechanism and a laser device to solve the technical problem that optical fibers are easily damaged.

[0030] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0031] Please refer to Figure 1 and Figure 2 This application provides a fixing mechanism, including a support platform 100, a fixing component 200, and a reflector 300.

[0032] Two fixing components 200 are provided, and the two fixing components 200 are spaced apart on the support platform 100, forming a suspension position 400 between the two fixing components 200. The reflector 300 is provided on the support platform 100 and is located on the side of the suspension position 400 close to the support platform 100. The reflector 300 is provided with a reflective inclined surface 310 that is inclined towards the suspension position 400.

[0033] It is understandable that the support platform 100 is used as a support structure to be installed on the frame of the laser equipment, and in the laser equipment, the support platform 100 is located below the scanning galvanometer of the laser equipment.

[0034] It is understood that the laser device with the fixing mechanism of the present application embodiment can not only be used to clean the coating on the workpiece 500, but also for laser cutting, drilling or etching, etc.

[0035] Taking cleaning the coating on the workpiece 500 as an example: two fixing components 200 clamp the same workpiece 500, so that part of the workpiece 500 is suspended between the two fixing components 200; the laser in the laser device is turned on, and the laser emitted by the laser is emitted through the scanning galvanometer and irradiates the suspended part of the workpiece 500; after continuous irradiation for a certain period of time, the coating on the workpiece 500 cracks; then the workpiece 500 is removed and the cracked coating is wiped off, and the coating can be cleaned.

[0036] It should be noted that the suspended position 400 refers to the space between two fixed components 200 that are spaced apart.

[0037] Understandably, the two spaced-apart fixed components 200 form a symmetrical clamping structure, which can provide stable support and positioning for the workpiece 500, avoiding processing deviations caused by displacement of the workpiece 500 during processing, and can also fully expose the processing area of ​​the workpiece 500 through the design of the suspended position 400, without blocking the laser irradiation path, thus balancing clamping stability and processing feasibility.

[0038] It is understandable that black structures such as black tape or black coatings can be applied to the workpiece 500. These black structures can efficiently absorb the photon energy of the laser, causing them to heat up rapidly and transfer heat to the coating, leading to thermal expansion and cracking. This not only improves laser utilization and cleaning efficiency but also allows the fixing mechanism of this embodiment to be applied to laser devices where photon energy cannot be absorbed by the coating (e.g., laser devices with MOPA fiber lasers).

[0039] In this embodiment, when the laser irradiates the workpiece 500, the laser is refracted by the reflective inclined plane 310 and then dispersed in a direction away from the suspended position 400. This avoids the risk of the reflected laser irradiating the workpiece 500 a second time, and prevents local energy concentration, uneven stress, surface ablation or internal structural damage to the workpiece 500 caused by laser reflection.

[0040] Optionally, the tilt angle formed by the reflective ramp 310 and the table surface of the support platform 100 is in the range of 30°-60°, such as 35°, 40°, 45°, 50°, and 55°. The tilt angle can be flexibly adjusted according to the laser incident direction, the size of the workpiece 500, and the processing requirements. It is understandable that the reflector 300 can be made of a highly reflective material that has been polished (such as stainless steel, aluminum foil coating, ceramic reflector, etc.). A highly reflective coating (such as vacuum-plated aluminum coating, silver-based composite coating, ceramic-based highly reflective coating, etc.) can also be applied to the reflective slope 310.

[0041] It is understandable that a laser-resistant coating (such as a zirconium oxide coating) can be applied to the reflector 300 to improve its high-temperature resistance and laser erosion resistance.

[0042] In the fixing mechanism provided in the first aspect embodiment of this application, two fixing components 200 clamp the workpiece 500 to be processed, so that the workpiece 500 is suspended in the suspension position 400. When the laser irradiates the workpiece 500, the reflecting slope 310 can reflect it. Since the reflecting slope 310 is inclined towards the suspension position 400, the reflecting slope 310 can reflect the laser away from the suspension position 400, so as to prevent the laser from being reflected onto the workpiece 500 located in the suspension position 400, thereby preventing the workpiece 500 from being subjected to uneven impact, and preventing damage to the workpiece 500.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, two reflective ramps 310 are provided, and the two reflective ramps 310 intersect to form a sharp angle protruding toward the suspended position 400.

[0044] In the above embodiment, the sharp corners formed by the two reflective inclined surfaces 310 protrude toward the suspended position 400, so that the laser propagating from different positions (such as the sides and bottom edge) of the workpiece 500 is received by the corresponding reflective inclined surfaces 310 and guided to the sides of the workpiece 500, so as to avoid the reflected laser from returning to the workpiece 500.

[0045] Please refer to Figure 1 In some embodiments, the intersection line 320 of the two reflective ramps 310 is parallel to the spacing direction of the two fixing components 200.

[0046] In the above embodiment, since the intersection line 320 of the two reflective inclined surfaces 310 is parallel to the spacing direction of the fixing component 200 (i.e., the clamping and fixing direction of the workpiece 500), the sharp corner formed by the two reflective inclined surfaces 310 extends along the length direction of the workpiece 500. This allows laser light at any position along the length of the workpiece 500 (such as near the clamping areas at both ends or in the middle processing area) to be received by the corresponding reflective inclined surface 310 and guided away from the suspended position 400. Compared to a structure where the intersection line 320 is perpendicular to the spacing direction of the fixing component 200, this avoids the reflected laser light from the longitudinal edge of the workpiece 500 from being deflected due to exceeding the coverage of the reflective surface, thus eliminating longitudinal reflection dead angles.

[0047] Optionally, the fixing component 200 can fix the workpiece 500 to be processed by magnetic positioning. For workpieces 500 made of magnetic metal, the fixing component 200 can have a built-in permanent magnet or electromagnetic coil, which magnetically attracts the workpiece 500. The electromagnetic coil can control the magnetic strength by adjusting the current, adapting to workpieces 500 of different thicknesses.

[0048] Optionally, the fixing component 200 can fix the workpiece 500 to be processed by vacuum adsorption. The fixing component 200 is provided with multiple adsorption holes, which are connected to the vacuum pump through air channels. The two ends of the workpiece 500 to be processed are adsorbed by negative pressure to achieve non-contact fixing and avoid deformation of the workpiece 500 caused by mechanical clamping.

[0049] Optionally, the fixing component 200 can fix the workpiece 500 to be processed in a mechanical clamping manner; please refer to [reference needed]. Figure 4 and Figure 5 The fixing component 200 includes a carrier 210 and a pressing member 220. The carrier 210 is disposed on the support platform 100 and has a bearing surface 211 facing away from the support platform 100. The pressing member 220 is connected to the carrier 210 and faces the bearing surface 211.

[0050] In the above embodiment, the workpiece 500 to be processed is placed on the bearing surface 211 of the two fixing components 200. By adjusting the distance between the holding member 220 and the bearing surface 211, the holding member 220 presses against the top of the workpiece 500, clamping the workpiece 500 between the holding member 220 and the bearing member 210, thereby achieving axial positioning of the workpiece 500. At the same time, the bearing members 210 of the two fixing components 200 are arranged in the length direction of the workpiece 500, restricting the longitudinal displacement of the workpiece 500, and finally forming a dual fixing effect of axial clamping and longitudinal positioning.

[0051] Please refer to Figure 5 In some embodiments, the support member 210 is provided with a support groove 212, which extends along the interval direction of the two fixing components 200, and the opening of the support groove 212 is located on the support surface 211.

[0052] In the above embodiment, the bearing groove 212 extends along the interval direction of the two fixing components 200 (i.e., the length direction of the workpiece 500), and the length of the bearing groove 212 is adapted to the length of the workpiece 500, ensuring that the workpiece 500 can be placed stably along the length direction of the bearing groove 212. The sidewall of the bearing groove 212 achieves lateral positioning of the workpiece 500, preventing the workpiece 500 from shifting laterally due to vibration or laser impact during processing.

[0053] Furthermore, in the above embodiments, for the easily bendable long workpiece 500, the bottom of the bearing groove 212 and the two side walls form an enclosed support, dispersing the weight of the workpiece 500 itself and the external force during the processing, which can reduce the bending deformation of the workpiece 500.

[0054] In the above embodiments, the holding member 220 and the bearing member 210 are detachably connected (e.g., bolted connection, snap-fit ​​connection) or movably connected (e.g., hinge connection).

[0055] Please refer to Figure 4 and Figure 5 In some embodiments, the holding member 220 has a first end 221 and a second end 222 disposed opposite to each other. The first end 221 is rotatably connected to the carrier member 210, and the second end 222 is detachably connected to the carrier member 210.

[0056] In the above embodiment, the holding member 220 is generally rod-shaped or plate-shaped. The first end 221 is rotatably connected to the side wall or top edge of the bearing member 210 through a rotating connector (such as a hinge, pivot, or damping hinge), with a rotation angle range of 0°-90° (0° is the holding state, and 90° is the open state). The second end 222 is fixed to the bearing member 210 through a detachable connection structure to form a stable holding state.

[0057] Optionally, the detachable connection of the second end 222 can be a snap-fit ​​type. For example, the second end 222 of the holding member 220 is provided with an elastic snap (such as a metal spring or a plastic claw), and the corresponding position of the bearing member 210 is provided with a slot. The snap-fit ​​and the slot are engaged to achieve quick fixation, and the snap-fit ​​can be unlocked by pressing the snap-fit. Optionally, the detachable connection of the second end 222 can be threaded. For example, the second end 222 of the clamping member 220 is provided with a threaded hole, and the bearing member 210 is provided with a stud at the corresponding position, and the fixing is achieved by tightening the bolt. Optionally, the detachable connection of the second end 222 can be magnetic. For example, the second end 222 of the holding member 220 has a built-in magnet, and the corresponding position of the bearing member 210 is provided with a magnetic adsorption block. It is fixed by magnetic adsorption, so as to realize quick opening and closing without tools.

[0058] In some embodiments, the holding member 220 includes a holding portion and an elastic portion, the holding portion being connected to the bearing member 210, and the elastic portion being disposed on the side of the holding portion facing the bearing surface 211.

[0059] In the above embodiment, the principle of clamping the workpiece 500 is as follows: After the workpiece 500 is placed in the bearing groove 212, the clamping member 220 is flipped and the second end 222 is fixed. The clamping part drives the elastic part to press against the top of the workpiece 500. Under the action of the clamping force, the elastic part undergoes elastic deformation, and the restoring force generated by the deformation tightly adheres to the surface of the workpiece 500, realizing flexible clamping and preventing damage to the workpiece 500. The elastic deformation of the elastic part can compensate for the thickness deviation or surface unevenness of the workpiece 500, ensuring that the clamping force is evenly applied to the workpiece 500 and improving the versatility of the fixing mechanism.

[0060] Furthermore, in the above embodiment, the elastic part can absorb the impact force during the pressing process, reducing contact wear between the pressing part and the workpiece 500. Simultaneously, the elastic material possesses excellent fatigue resistance, allowing for repeated deformation without failure, thus extending the service life of the pressing part 220. In addition, the elastic part can be disassembled and replaced separately, eliminating the need to replace the entire pressing part 220, thereby reducing maintenance costs.

[0061] Understandably, the elastic part is made of materials such as silicone, rubber, and elastic plastic.

[0062] Please refer to Figure 2 and Figure 4 In some embodiments, the support platform 100 includes a guide rail 110, a fixing component 200 slidably disposed on the guide rail 110, and the fixing component 200 having a locking member 230 for clamping the guide rail 110.

[0063] In the above embodiment, depending on the length of the workpiece 500, the locking members 230 of the two fixing components 200 can be loosened, and the fixing components 200 can be slid along the guide rail 110 to adjust the distance between the two fixing components 200; after confirming the distance, the locking members 230 are tightened to lock the fixing components 200 on the guide rail 110, ensuring that the position of the two fixing components 200 remains unchanged during the processing; if it is necessary to change the workpiece 500 of different lengths, the above steps can be repeated for quick adjustment.

[0064] In the above embodiment, the carrier 210 is disposed on the locking member 230, and the locking member 230 is slidably mounted on the guide rail 110 to drive the carrier 210 and the pressing member 220 to move. For example Figure 6 As shown, the locking member 230 includes a base 231 (with the support member 210 disposed on the base 231), a first clamping member 232, and a second clamping member 233. The first clamping member 232 and the second clamping member 233 are disposed on the base 231 and are respectively located on both sides of the guide rail 110. At least one of the first clamping member 232 and the second clamping member 233 is movably disposed on the base 231, such that the distance between the first clamping member 232 and the second clamping member 233 is variable. The distance between the first clamping member 232 and the second clamping member 233 can be reduced, so that the first clamping member 232 and the second clamping member 233 clamp the guide rail 110 to lock the fixing assembly 200 onto the guide rail 110. The distance between the first clamping member 232 and the second clamping member 233 can be increased, so that the first clamping member 232 and the second clamping member 233 release the guide rail 110, so that the fixing assembly 200 can slide along the guide rail 110.

[0065] Please refer to Figure 1 In the above embodiment, in the extending direction of the guide rail 110, the carrier 210 protrudes beyond the locking member 230, forming a clearance space 240 between the locking member 230 and the carrier 210. That is, one end of the carrier 210 facing the other fixing component 200 extends beyond the end face of the locking member 230, forming an "L"-shaped clearance space 240 between the carrier 210 and the locking member 230. The reflector 300 is disposed in the middle of the support platform 100 along the extending direction of the guide rail 110, with both ends extending towards the clearance spaces 240 of the two fixing components 200, and the extended ends of the reflector 300 and the carrier 210 overlapping in a direction perpendicular to the guide rail 110. The bottom of the reflector 300 is fixedly connected to the support platform 100 (e.g., bolted, slotted), and the double reflective slope 310 at the top maintains a sharp angle structure facing the suspended position 400, ensuring that the reflection function is not affected by position adjustment.

[0066] As the length of the workpiece 500 increases, the locking member 230 is released and the fixed component 200 slides along the guide rail 110. The bearing member 210 moves away from the reflector 300, and the clearance space 240 gradually moves away from the end of the reflector 300 as the fixed component 200 moves. Part of the reflector 300 is exposed from the clearance space 240, which increases the effective reflection length of the reflective slope 310 and expands the reflection range simultaneously, avoiding missed reflection of laser light caused by the adjustment of the distance between the two fixed components 200.

[0067] Please refer to Figure 6 In some embodiments, the first clamping member 232 is rotatably mounted on the base 231, and the axis of rotation of the first clamping member 232 is perpendicular to the extension direction of the guide rail 110. The first clamping member 232 is in rolling contact with the guide rail 110. The second clamping member 233 is movable relative to the base 231 to change the distance between the second clamping member 233 and the first clamping member 232.

[0068] In the above embodiment, the rolling contact between the first clamping component 232 and the guide rail 110 transforms the surface friction of traditional sliding contact into point friction or line friction, thereby reducing the coefficient of friction and significantly reducing the driving force required for the fixing component 200 to move along the guide rail 110. Operators can easily slide the fixing component 200 without applying a large pushing force, reducing operational intensity and improving adjustment efficiency.

[0069] Optionally, the first clamping component 232 is a ball or a roller.

[0070] Optionally, the second clamping component 233 can clamp the guide rail 110 using an eccentric locking mechanism. For example, the second clamping component 233 includes an eccentric adjustment part 233-1, which is rotatably mounted on the base 231. The rotation axis of the eccentric adjustment part 233-1 is perpendicular to the guide rail 110 and is eccentrically positioned. Rotating the eccentric adjustment part 233-1 causes it to press against the side of the guide rail 110, thus locking it. Rotating the eccentric adjustment part 233-1 in the opposite direction unlocks it.

[0071] like Figure 6 As shown, the second clamping component 233 also includes a supporting part 233-2, which includes a fixed end and a free end. The fixed end is fixed to the base 231, and the free end is located between the eccentric adjustment part 233-1 and the guide rail 110. Rotating the eccentric adjustment part 233-1 causes the free end to move closer to the guide rail 110 and press against the side of the guide rail 110, thus locking it. Rotating the eccentric adjustment part 233-1 in the opposite direction causes the free end to move away from the guide rail 110, thus unlocking it.

[0072] It is understandable that the supporting part 233-2 is a spring sheet that can be elastically deformed. The fixed end is fixed to the base 231 by bolts, welding or buckles, and the free end is in a suspended state.

[0073] Optionally, the second clamping component 233 can clamp the guide rail 110 using a threaded locking method. For example, the second clamping component 233 includes a support portion and a locking bolt. The support portion is fixedly mounted on the base 231, and the locking bolt is threaded through the support portion. When the locking bolt is tightened, the end of the locking bolt presses against the guide rail 110, locking the position of the fixing component 200 through friction. Reverse rotation of the locking bolt increases the distance between the locking bolt and the second clamping component 233, allowing the fixing component 200 to slide relative to the guide rail 110. The end of the locking bolt may be provided with an anti-slip pad (such as a rubber head) to enhance locking stability and prevent scratching the surface of the guide rail 110. This application provides a laser device, including the fixing mechanism described in the first aspect embodiment above.

[0074] By applying the aforementioned fixing mechanism to the laser equipment, the laser equipment prevents the workpiece 500 from being subjected to uneven impacts when cleaning the coating on the workpiece 500, thereby preventing damage to the workpiece 500.

[0075] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
