Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to a winding structure and a laser. Background Technology

[0002] The laser is equipped with a winding spool for winding optical fiber. One end of the optical fiber is connected to the first device, and the other end of the optical fiber is introduced from the lower end of the winding spool, then wound around the side wall of the winding spool from bottom to top, and finally led out from the upper end of the winding spool and connected to the second device.

[0003] The fiber is wound on the winding reel, which results in the two ends of the fiber being located at the top and bottom of the winding reel, respectively. This means that the first and second devices that connect with the fiber must be located at the top and bottom of the winding reel, respectively. This results in low space utilization and affects the arrangement of other structures in the laser. It also leads to an increased number of fixed components in other cooperating structures, resulting in a larger laser size and increased cost.

[0004] In addition, existing technologies also have problems such as changes in the fiber winding radius, incompatibility with different fiber lengths, large space occupation of the fiber optic coil, and poor heat dissipation performance.

[0005] Therefore, it is necessary to study a winding structure and a laser to solve at least one of the above problems. Summary of the Invention

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0064] Example 1

[0065] like Figures 1-10 As shown, the winding structure provided by this invention can wind and fix the optical fiber 05, such as... Figure 7 As shown.

[0066] like Figure 6 As shown, the winding structure includes a winding post 22, which is roughly cylindrical in shape. The winding post 22 includes a first end 28 and a second end 29 that are arranged opposite to each other along its axial direction. In this embodiment, for ease of understanding, the second end 29 is assumed to be the upper end of the winding post 22, and the first end 28 is assumed to be the lower end.

[0067] like Figure 3 , Figure 4 and Figure 6 As shown, a first winding groove 26 is provided on the circumferential sidewall of the winding post 22, spirally extending axially from the first end 28 toward the second end 29. The upper port of the first winding groove 26 forms a first outlet 30, which is located at the second end 29. The first winding groove 26 may have a lower port, which is a first inlet port. The optical fiber 05 is introduced into the first winding groove 26 from the lower port. Alternatively, the first winding groove 26 may not have a lower port, i.e., the lower end of the first winding groove 26 is closed, and the optical fiber 05 is spirally introduced into the first winding groove 26 from a position near the first end 28.

[0068] A transition groove 16 is provided on the end face of the second end 29 of the winding post 22. The transition groove 16 includes a second inlet 31 and a second outlet 32. The optical fiber 05 led out from the first winding groove 26 is introduced into the second winding groove 27 through the transition groove 16.

[0069] Similarly, such as Figure 4 and Figure 6 As shown, a second winding groove 27 is provided on the circumferential sidewall of the winding post 22, spirally wound along the axial direction. The second winding groove 27 extends from the second end 29 toward the first end 28. The first winding groove 26 and the second winding groove 27 are staggered in the axial direction of the winding post 22, that is, each single-turn arc segment of the first winding groove 26 and each single-turn arc segment of the second winding groove 27 are alternately arranged in the axial direction. The upper port of the second winding groove 27 forms a third inlet 33, which is located at the second end 29. The optical fiber 05 led out from the second outlet 32 ​​of the transition groove 16 enters the third inlet 33 of the second winding groove 27, and is wound from top to bottom before being led out from the first end 28 of the winding post 22.

[0070] Similar to the first winding groove 26, the second winding groove 27 may have a lower port, i.e., the lower port is the third outlet, or it may not have a lower port, i.e., the lower end of the second winding groove 27 is closed, and the optical fiber 05 is spirally led out from the groove opening of the second winding groove 27 from a certain position near the first end 28.

[0071] like Figure 6 and Figure 7 As shown, during winding, the optical fiber 05 can be introduced from the first winding groove 26 near the first end 28 and wound from bottom to top within the first winding groove 26. When wound to the second end 29, the optical fiber 05 is led out from the first outlet 30 and simultaneously enters the transition groove 16 through the second inlet 31. After passing through the transition groove 16, it is led out from the second outlet 32 ​​and simultaneously enters the second winding groove 27 through the third inlet 33. Then, it extends from top to bottom along the second winding groove 27 from the second end 29 to... The first end 28 is finally led out from the second winding groove 27 near the first end 28. For the winding structure, the input end and output end of the optical fiber 05 are both set on the side near the first end 28 (the side where the first end 28 is located), so that the components connected to both ends of the optical fiber 05 can be set on the same side. Only a fixing structure for fixing both ends of the optical fiber 05 needs to be set at the same end of the winding structure. The space setting is more reasonable and avoids occupying the space on both sides of the first end 28 and the second end 29 of the winding structure at the same time.

[0072] Different laser devices require different lengths of fiber optic cable 05. Therefore, the lengths of the first winding groove 26 and the second winding groove 27 are adjustable, which allows the winding structure to be adapted to different types of lasers.

[0073] like Figure 5 As shown, in this embodiment, the winding post 22 includes multiple post units arranged sequentially along the axial direction, and adjacent post units can be detachably connected; each post unit has a first groove unit and a second groove unit arranged in a staggered manner along the axial direction on its circumferential outer wall, and the multiple first groove units on the assembled multiple post units are connected end to end to form a first winding groove 26; the multiple second groove units on the assembled multiple post units are connected end to end to form a second winding groove 27.

[0074] After the upper and lower ends of two adjacent column units are connected, the first slot unit of the previous column unit and the first slot unit of the next column unit are connected to form a continuous through slot structure. Similarly, the upper and lower second slot units are also connected to form a continuous through slot structure. Therefore, when all column units are connected end to end in sequence, the first winding slot 26 and the second winding slot 27 are formed.

[0075] The number of column units is at least two. When there are two column units, the two column units are respectively set as the upper cover 02 and the chassis 01, and the transition groove 16 is set on the upper cover 02. When there are three or more column units, the two column units at the beginning and end can be set as the upper cover 02 and the chassis 01, and the column unit between the upper cover 02 and the chassis 01 is set as the extension part 03. The number of extension parts 03 is at least one. In this embodiment, the number of extension parts 03 is 6. By increasing or decreasing the number of extension parts 03, the length of the first winding groove 26 and the second winding groove 27 can be adjusted to adapt to optical fibers 05 of different lengths.

[0076] The column units can be connected by a second fastener 10, which includes a bolt that passes through the upper cover 02 and the extension 03 in sequence before being threaded onto the chassis 01. Alternatively, in other feasible solutions, the column units can also be connected by snap-fit ​​connections.

[0077] like Figure 6 As shown, the transition groove 16 includes a first arc-shaped segment 161, and the second inlet 31 is one port of the first arc-shaped segment 161; the first arc-shaped segment 161 transitions with the first winding groove 26 by an arc, preventing the optical fiber 05 from bending at a large angle at the connection point of the first winding groove 26 and the transition groove 16. The transition groove 16 includes a second arc-shaped segment 162, and the second outlet 32 ​​is one port of the second arc-shaped segment 162; the second arc-shaped segment 162 transitions with the second winding groove 27 by an arc, preventing the optical fiber 05 from bending at a large angle at the connection point of the second winding groove 27 and the transition groove 16.

[0078] The first arc segment 161 and the second arc segment 162 have opposite bending directions, and the other port of the first arc segment 161 relative to the second inlet 31 and the other port of the second arc segment 162 relative to the second outlet 32 ​​are arc transitioned, that is, the transition groove 16 is "S" shaped, and the optical fiber 05 is arc-shaped and coiled in the transition groove 16 to avoid large-angle bending of the optical fiber 05.

[0079] Example 2

[0080] Unlike the length adjustment method in Embodiment 1, in this embodiment, the winding post 22 includes a main body with an axial length adjustable, and a flexible sleeve sleeved on the outside of the main body, which can extend and retract along the axial direction of the main body. A transition groove 16 is provided on the main body, and the first winding groove 26 and the second winding groove 27 are both provided on the sleeve.

[0081] The main body is located on the outside of the sleeve and provides support. The flexible sleeve is similar in shape to a corrugated pipe, but the grooves on the outer wall of the corrugated pipe are annular grooves, and multiple annular grooves are arranged sequentially along the axial direction and are independent of each other. In this embodiment, the first winding groove 26 and the second winding groove 27 on the outer wall of the sleeve are continuous grooves spirally wound along the axial direction. According to the length of the optical fiber 05, the user compresses a portion of the sleeve from the lower end (the end away from the transition groove 16). The first winding groove 26 and the second winding groove 27 on the compressed portion close, and the overall length of the first winding groove 26 and the second winding groove 27 is shortened. Therefore, by controlling the length of the compressed portion, the length of the first winding groove 26 and the second winding groove 27 can be adjusted, and the interval between two adjacent single-turn grooves of the first winding groove 26 and the interval between two adjacent single-turn grooves of the second winding groove 27 can be adjusted respectively. Correspondingly, when the length of the sleeve is adjusted to a suitable length, the length of the main body can be adjusted accordingly. By means of telescoping, the length can be quickly adjusted, and the disassembly and assembly steps between parts are reduced, making it more convenient for the user.

[0082] The main body includes a first part and a second part, which are connected, and the first part can be retracted into or extended from the second part.

[0083] Furthermore, the main body can be a telescopic tube, for example, comprising two tubes of different thicknesses, namely corresponding to a first part and a second part. The first part is a thin tube and the second part is a thick tube. The upper opening of the second part is closed to provide a transition groove 16. One end of the first part is inserted into the lower opening of the second part, thereby fixing the first part and the second part together.

[0084] The methods by which the first and second parts are fixed include, but are not limited to, the outer diameter of the first part being approximately equal to the inner diameter of the second part or an interference fit, to ensure that their contact surfaces are tightly pressed together, providing significant friction so that the telescopic tube will not easily shorten or lengthen automatically after the user actively adjusts the length. It is understood that the first and second parts can also be fixed to each other through other connection methods.

[0085] Example 3

[0086] like Figures 1-6 As shown, the laser provided by the present invention includes an optical fiber 05, a fan 12, and the aforementioned winding structure; the optical fiber 05 is wound and fixed on the winding structure; the winding post 22 is provided with a first air port 171 and a second air port 172, as shown. Figure 6 and Figure 7 As shown, the winding post 22 has an air passage 17 inside that connects the first air port 171 and the second air port 172. One of the first air port 171 and the second air port 172 is an air inlet, and the other is an air outlet.

[0087] The fan 12 includes a first air inlet 25 and a second air inlet 36. In this embodiment, the first air inlet 25 is for air intake, and the second air inlet 36 is for air exhaust. The first air inlet 25 is connected to the first air outlet 171. The fan 12 is used to form a downward airflow within the air duct 17. The airflow formed by the fan 12 within the air duct 17, after passing through the winding post 22, dissipates heat from the optical fiber 05 on the winding post 22.

[0088] Furthermore, the wind speed of fan 12 can be adjusted and controlled according to the winding length of optical fiber 05. This ensures the heat dissipation effect of optical fiber 05 while also achieving energy saving.

[0089] Furthermore, the opening degree of the first air port 171 and the second air port 172 can be adjusted and controlled according to the winding length of the optical fiber 05, so as to ensure the heat dissipation effect of the optical fiber 05 and achieve the energy-saving effect.

[0090] like Figure 6 As shown, the winding post 22 has multiple air channels 17, and second air ports 172 are disposed on the end face of the second end 29. These multiple second air ports 172 are evenly distributed on the end face. In this embodiment, some of the second air ports 172 are fan-shaped, and these fan-shaped second air ports 172 are arranged around the center of the end face of the second end 29. Some of the second air ports 172 are strip-shaped and centrally located in the middle region of the end face. The air channels 17 extend axially, and the solid structure between two adjacent air channels 17 forms a first heat dissipation fin 18, increasing the contact area with the gas.

[0091] In this embodiment, as Figures 5-7 , Figure 10 As shown, the fan 12 is a vortex fan 12, which can create negative pressure. Outside air enters the fan 12 through the first air inlet 25 and then exits through the second air inlet 36. Therefore, the airflow in the winding post 22 flows from the second air inlet 172 to the first air inlet 171. Of course, in other feasible solutions, the first air inlet 25 of the fan 12 can also be an opening for exhausting airflow, in which case the airflow in the air duct 17 will flow from the first air inlet 171 to the second air inlet 172.

[0092] like Figure 2 and Figure 6 As shown, the laser also includes an airflow adjustment structure 23, which is connected to the winding post 22. The airflow adjustment structure 23 adjusts the opening of the second air port 172 according to the length of the optical fiber 05 wound on the winding structure.

[0093] like Figure 1 , Figure 2 and Figure 5As shown, to ensure that the optical fiber 05 operates within its optimal temperature range, in this embodiment, the opening of the second air port 172 is adjustable, thereby changing the flow rate of the gas flowing through the air passage 17. A higher flow rate results in better heat dissipation and a lower temperature for the optical fiber 05. However, a lower operating temperature for the optical fiber 05 is not always better. The amount of heat emitted by the optical fiber 05 is related to its length; therefore, the final temperature of the optical fiber 05 is affected by both its length and the airflow rate within the air passage 17. Thus, once the length of the optical fiber 05 is known, by setting an appropriate airflow rate, the final temperature of the optical fiber 05 can be controlled within a preset range.

[0094] like Figure 5 As shown, the air volume regulating structure 23 includes a cover plate 06 and a valve plate 07. The cover plate 06 is provided with a first air guide port, which is connected to a second air port 172. The valve plate 07 is movably connected to the cover plate 06 so that the valve plate 07 can move relative to the cover plate 06 to a fully open state or a closed state. In the fully open state, the valve plate 07 is misaligned with the first air guide port, and the first air guide port is completely open. In the closed state, the valve plate 07 completely or partially blocks the first air guide port.

[0095] The valve plate 07 and the cover plate 06 are coaxially connected via a rotating shaft 08. The cover plate 06 can be connected to the upper cover 02 via a first fastener 09. The cover plate 06 serves to protect the optical fiber 05. The valve plate 07 can rotate relative to the cover plate 06. By rotating the valve plate 07, the area of ​​the valve plate 07 blocking the first air guide port can be changed, thereby adjusting the opening of the first air guide port and thus changing the flow rate of the air entering the second air port 172.

[0096] In this embodiment, the valve plate 07 is rotated manually by the user.

[0097] In other possible solutions, the laser may also include a motor and a controller. The output shaft of the motor is connected to the valve plate 07 to drive the valve plate 07 to rotate. The controller is electrically connected to the motor. The user inputs the length information of the optical fiber 05 into the controller. The controller obtains the rotation angle of the valve plate 07 according to its pre-stored logic to control the motor to rotate the corresponding angle, thereby realizing the automatic adjustment of the flow channel in the air passage 17.

[0098] like Figure 3 and Figure 9 As shown, the first end 28 is the lower end of the winding post 22; the laser includes a mounting base 04, and a first recessed platform 20 is provided on the top surface of the mounting base 04. The first recessed platform 20 is used to position and install the first end 28 of the winding post 22; a through hole 34 is provided on the mounting base 04 to connect the top surface and the bottom surface of the mounting base 04; the through hole 34 is located inside the first recessed platform 20; the fan 12 is located on one side of the bottom surface of the mounting base 04; the first air port 171 is provided on the end face of the first end 28 of the winding post 22.

[0099] The first recessed platform 20 is recessed to position and install the winding post 22. The first end 28 of the winding post 22 is inserted into the first recessed platform 20, and the outer circumferential wall of the winding post 22 fits against the inner circumferential wall of the first recessed platform 20, essentially forming a seal and reducing air leakage. The fan 12 is located below the mounting base 04, and applies negative pressure to the first air port 171 on the end face of the first end 28 of the winding post 22 through the through hole 34 on the mounting base 04.

[0100] like Figure 8 As shown, in order to avoid occupying the circumferential space of the winding post 22, a downwardly extending limiting boss 21 is provided on the end face of the first end 28. The limiting boss 21 matches the shape and size of the first recess 20 so that the limiting boss 21 can be inserted into the first recess 20.

[0101] The winding post 22 is movably connected to the mounting base 04 so that the position of the first end 28 of the winding post 22 in the depth direction of the first recess 20 is adjustable, and the first recess 20 and the end face of the first end 28 of the winding post 22 form a mixing chamber 24.

[0102] The greater the distance between the end face of the first end 28 and the bottom surface of the first sink 20, the larger the volume of the mixing chamber 24. The larger the volume of the mixing chamber 24, the longer the gas stays there, and the longer the contact time with the winding post 22, resulting in a better heat absorption effect. Therefore, based on the length of the optical fiber 05, the flow rate of the gas channel 17 can be adjusted by changing the volume of the mixing chamber 24, thereby adjusting the heat dissipation capacity of the winding post 22 so that the final temperature of the optical fiber 05 is within the expected range.

[0103] like Figure 3 and Figure 5 As shown, specifically in this embodiment, a height adjusting bolt 11 is rotatably connected to the mounting base 04. Its height position remains unchanged relative to the mounting base 04 (a vertical limiting groove or limiting piece can be provided). The height adjusting bolt 11 can only rotate relative to the mounting base 04. The tail end of the height adjusting bolt 11 passes through the mounting base 04 and is threadedly connected to the winding post 22. By rotating the height adjusting bolt 11, the length of the part of the height adjusting bolt 11 extending out of the winding post 22 can be changed, thereby raising or lowering the winding post 22 relative to the mounting base 04.

[0104] like Figure 7 As shown, a second recessed platform 35 is provided on the end face of the first end 28 of the winding post 22; the first air port 171 is provided in the second recessed platform 35.

[0105] The second sinking platform 35 can be set on the lower surface of the chassis 01. By setting the second sinking platform 35, the initial volume of the mixing chamber 24 (the volume of the mixing chamber 24 when the end face of the first end 28 is completely in contact with the first sinking platform 20) can be further increased, avoiding setting the first sinking platform 20 too deep.

[0106] like Figure 8 As shown, the inner wall of the annular hollow column unit (or chassis 01) is provided with a heat dissipation protrusion 19 protruding towards the center. The heat dissipation protrusion 19 is located in the mixing chamber 24 to increase the contact area with the airflow.

[0107] like Figure 5 , Figure 9 and Figure 10 As shown, the first air outlet 25 of the fan 12 is located below the through hole 34, and is connected to the mounting base 04 by the third fastener 13, and faces the through hole 34; in the vertical direction, the center of the first air outlet 25 is offset from the center of the cavity of the through hole 34, the mixing chamber 24 is located above the through hole 34, and the mixing chamber 24 is concentric with the through hole 34.

[0108] like Figure 3 and Figure 10 As shown, the airflow from the first air outlet 171 first enters the mixing chamber 24, where it further contacts the winding post 22. Furthermore, since the center of the first air outlet 25 is misaligned with the center of the through hole 34, the gas flowing out of the first air outlet 171 does not directly enter the fan 12. Instead, it turns within the mixing chamber 24, bending before entering the fan 12. This increases the residence time and further improves the heat absorption efficiency.

[0109] like Figure 1 As shown, the mounting base 04 is provided with fins 15 to increase the heat dissipation capacity of the mounting base 04. The mounting base 04 is provided with an exhaust channel 14 that avoids the first air outlet 25 of the fan 12.

[0110] Example 4

[0111] like Figure 11 As shown, in this embodiment, the depth adjustment method of the second sinking platform 35 is different from that in embodiment 3.

[0112] Figure 11 In the middle m region, the winding post 22 includes multiple first post units 37 arranged sequentially from top to bottom along the axial direction, with adjacent first post units 37 detachably connected. Each first post unit 37 has a through-hole extending from top to bottom, and the through-holes on the multiple first post units 37 are interconnected vertically to form an air passage 17, which is the same as in Embodiment 3. The difference is... Figure 11In the middle n region, the winding post 22 also includes multiple second post units 38 arranged sequentially from top to bottom along the axial direction; the uppermost second post unit 38 is connected to the lowermost first post unit 37. The shape of the second post unit 38 is different from that of the first post unit 37. The second post unit 38 has a ring-shaped hollow structure, that is, the middle part is completely hollow. The ring-shaped hollow structure of multiple second post units 38 forms a second recessed platform 35. According to the length of the optical fiber 05, an appropriate number of second post units 38 are selected for assembly to obtain a second recessed platform 35 of appropriate depth, and finally a hybrid chamber 24 suitable for the length of the optical fiber 05 is obtained.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
