Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lasers, and particularly relates to a 980nm laser convenient to install. BACKGROUND

[0002] The fiber laser is a kind of laser using optical fiber as a gain medium, and its working principle is based on stimulated radiation and optical amplification effect. Specifically, the fiber laser is composed of a gain medium (an optical fiber doped with rare earth elements), a pump source, a resonant cavity and optical elements. The 980nm fiber laser is a kind of fiber laser, in particular, a laser with a working wavelength of 980nm. This kind of laser can not only be used as an important pump source for erbium-doped and ytterbium-doped fiber lasers and amplifiers, but also can obtain blue-green light of 490nm through nonlinear optical means such as frequency multiplication, and is widely used in optical communication, optical sensing, laser processing and medical treatment and other fields. Its main features include high-brightness output, efficient pump source and excellent beam quality.

[0003] In the prior art, due to different designs and production processes of different manufacturers. For example, some manufacturers may adopt a more compact design to reduce the size of the equipment, while other manufacturers may adopt a design that is easier to dissipate heat or maintain, thereby increasing the size of the equipment. Thus, the same power or wavelength pump sources produced by different manufacturers have a large difference in size. When the pump source is damaged or its performance decreases and needs to be replaced, the user may not be able to choose a pump source with superior performance or more advanced technology because they may not be compatible with the original size. If the original pump source is a specific model or has been discontinued, a higher price needs to be paid to purchase a replacement of the same size. It may take a longer time to find a pump source of the same size, which will cause the equipment downtime to be extended and affect the production efficiency. However, when the size of the new pump source is greatly different from the size of the original pump source, the pump source may not be directly installed on the original mounting plate, and an adapter needs to be designed and manufactured or the existing mounting structure needs to be modified. SUMMARY

[0004] The purpose of the present application is to provide a 980nm laser convenient to install, which can be used to fix pump sources of different sizes.

[0005] The 980nm laser convenient to install comprises a horizontally arranged shell and a top cover covering the shell, a mounting plate is horizontally arranged in the shell, a fixing assembly for fixing pump sources of different sizes is arranged on the mounting plate, auxiliary devices for laser processing and output are installed in the shell on one side of the mounting plate, and an air cooling system for balanced heat dissipation is arranged in the shell.

[0007] Further, the air cooling system includes a flow guide assembly arranged inside the shell above the mounting plate, the flow guide assembly includes a horizontally arranged flow guide plate, the left end of the flow guide plate is fixed on the left inner wall of the shell, the right end is bent downward and then fixed on the right side wall in the shell through a support, a plurality of left and right movable adjusting plates are placed on the flow guide plate in a left and right interval, fixed strips are fixed on the front and rear ends of the adjusting plates on the flow guide plate, the end portions of the adjusting plates are left and right slidingly matched with the corresponding fixed strips, the adjusting plates and the flow guide plate are both provided with air inlets which are communicated in the up and down directions, the air inlets on the adjusting plates and the air inlets on the flow guide plate are communicated with each other, and are used for sending air to the corresponding pump sources, the adjusting plates are both fixed with sliding blocks, the corresponding sliding blocks are provided with first sliding grooves which are left and right slidingly matched on the top cover, the upper ends of the sliding blocks independently pass through the first sliding grooves and then extend out of the top cover, the sliding blocks are moved left and right, the adjusting plates are moved left and right, and the size of the communication part of the air inlets on the adjusting plates and the air inlets on the flow guide plate is adjusted.

[0008] The right side wall of the shell is provided with a first heat dissipation fan for sending air inward, and the left side wall is provided with a second heat dissipation fan for sucking air outward.

[0009] The right end of the flow guide plate is fixed on the top of the support, the support is fixed on the left side wall in the shell, in the process of the first heat dissipation fan sending air inward, part of the air is blown from the right side of the mounting plate into the shell above and below the mounting plate to the left, and the other part of the air is backflowed through the bent part of the right end of the adjusting plate into the area between the flow guide plate and the top cover, the sliding blocks are moved left and right, the adjusting plates are moved left and right, the size of the communication part of the air inlets on the adjusting plates and the air inlets on the flow guide plate is adjusted, the size of the air volume through the air inlets is adjusted, the air inlets on the flow guide plate are located above the pump sources, can cool the top of the pump sources, when the number of pump sources is large, the size of the air volume through the air inlets is adjusted, the airflow direction can be effectively controlled, air is sent from the air inlets above the corresponding pump sources, the cooling air can accurately cool the corresponding pump sources, thereby improving the overall cooling efficiency, the hot air inside is sucked out through the second heat dissipation fan, the internal air convection is accelerated, and the cooling effect is good.

[0010] Furthermore, the support is two that are spaced apart on the left and right. The right end of the guide plate is fixed to the support on the right side, and the support on the left side is fixed inside the housing on the left side of the mounting plate. The left and right ends of the mounting plate are slidably mounted on the inner side of the corresponding support through telescopic slide rails.

[0011] The guide plate has multiple gourd-shaped holes spaced back and forth at both ends, and each gourd-shaped hole is equipped with a first bolt.

[0012] The top cover has an "L" shaped cross-section. The vertical section covers the rear of the housing, and the horizontal section covers the top. The left end of the guide plate is fixed to the inner wall of the left side of the housing via a first bolt inside the gourd hole at the small hole. The right end is fixed to the top of the support on the right side via a first bolt inside the gourd hole at the small hole. When internal maintenance is required, simply remove the top cover, loosen the first bolt, move the guide plate backward, align the thread of the first bolt with the large hole of the gourd hole, and lift the guide plate upward. This allows for quick removal of the guide plate without fully unscrewing the first bolt, preventing its loss. The mounting plate slides backward via a telescopic rail from the housing. Pulling out from the rear allows for quick opening of the housing, making maintenance and replacement more convenient. The right-side bracket is fixed to the right side wall inside the housing, thus splitting the airflow from the first cooling fan into the housing upon entry. Part of the air blows in from the right side of the mounting plate, directing it to the left within the housing above and below the mounting plate. The other part of the airflow is reversed through the right-side bend of the adjusting plate, entering the area between the guide plate and the top cover, enhancing the cooling control effect of the air inlet on the pump source. The left-side bracket is fixed to the left side of the mounting plate inside the housing, rather than to the left side wall inside the housing. With the cooperation of the second cooling fan, this increases air convection within the housing, improving the heat dissipation effect.

[0013] Furthermore, the fixing component includes a first fixing component for fixing the pump source in the front-rear direction. The first fixing component includes a first fixing block fixed to a mounting plate on one side of the pump source by a support block. The support block has a wire harness groove. The side of the first fixing block facing the pump source is inclined and a first slider is fixed thereon. The first slider has a first threaded countersunk hole machined at an angle. A first spring is independently provided in the countersunk section of the first threaded countersunk hole. A first pressure block is installed on the first slider and slides up and down with it. A first countersunk hole is opened on the first pressure block corresponding to the first threaded countersunk hole. A second bolt with a threaded engagement with the first threaded countersunk hole passes through the first countersunk hole and the first spring and then extends into the threaded section of the first threaded countersunk hole. The second bolt is tightened inward. The first spring is in a compressed state. The first pressure block moves downward along the inclined surface of the first fixing block to press the pump source.

[0014] A limiting block is fixed on the mounting plate on the other side of the pump source to limit the pump source in the front and rear directions.

[0015] The limiting block and the first pressing block are located on both sides of the pump source in the front and rear directions, respectively. The pump source is limited by the limiting block on the side facing the limiting block. Then, the second bolt is tightened inward on the other side of the pump source. The first pressing block, which is in vertical sliding cooperation with the first slider, slides downward and moves downward along the inclined surface of the first fixing block to press the pump source down, thereby quickly limiting and fixing the pump source. By moving the first pressing block up and down along the first fixing block, the front and rear distance between the first pressing block and the limiting block can be adjusted, thereby fixing pump sources of different lengths on the mounting plate.

[0016] Furthermore, the fixing assembly also includes a second fixing assembly for fixing the pump source in the left-right direction. The second fixing assembly includes a second fixing block fixed on the mounting plates on the left and right sides of the pump source. The side of the second fixing block facing the pump source is inclined and a second slider is fixed thereon. The second slider has a second threaded countersunk hole machined at an angle. A second spring is independently provided in the countersunk section of the second threaded countersunk hole. A second pressure block is installed on the second slider and slides up and down with it. The second pressure block has a second countersunk hole corresponding to the second threaded countersunk hole. A third bolt with a threaded engagement with the second threaded countersunk hole is inserted into the second countersunk hole. The screw of the third bolt passes through the second countersunk hole and the second spring and extends into the threaded section of the second threaded countersunk hole. The third bolt is tightened inward. The second spring is in a compressed state. The second pressure block moves downward along the inclined surface of the second fixing block to press the pump source.

[0017] Tighten the third bolt inward, and the second pressure block, which slides vertically with the second slider, slides downward and moves downward along the inclined surface of the second fixed block, pressing down on the pump source. This quickly limits and fixes the left and right sides of the pump source. By moving the second pressure block up and down along the second fixed block, the distance between the second pressure blocks on the left and right sides of the pump source can be adjusted, thus fixing pump sources of different widths on the mounting plate. At the same time, the pump source can be quickly fixed by tightening one second bolt and two third bolts, which is convenient. In addition, the second and third bolts are located in corresponding threaded holes, which can prevent them from falling off or being lost during maintenance. When there are many pump sources installed horizontally at intervals on the mounting plate, the two pump sources on the left and right sides can be fixed by the two second pressure blocks on the second fixed block, which is convenient for installation.

[0018] Furthermore, the front sidewall of the housing is provided with an output interface for laser output, the output end of the output interface is connected to an optical fiber, and the output end of the optical fiber is connected to an output head.

[0019] The bottom of the housing is provided with a connecting component, which includes a connecting post. A first placement groove is provided on the bottom of the housing corresponding to the connecting post. The upper end of the connecting post is fixed in the first placement groove. A slot is provided laterally on the side wall of the connecting post. A second sliding groove is provided on the connecting post at the top of the slot in the up-down sliding direction. The second sliding groove communicates with the slot and a top plate is slidably fitted inside it. A third spring is provided in the second sliding groove above the top plate. When the third spring is in a free state, the lower end of the top plate is located in the slot.

[0020] A fixing component is inserted into the slot. The fixing component includes a plug block inserted into the slot. The bottom of the connecting post has a threaded hole that communicates with the slot. A fixing plate is fixed to the threaded hole by a fourth bolt with threaded engagement. The outer end of the plug block is located outside the slot and is bent downwards and connected to the fixing plate by a fifth bolt. A positioning groove is provided on the plug block at the connection with the fixing plate. A positioning block that cooperates with the positioning groove is fixed on the fixing plate.

[0021] The diameter of the opening of the first placement slot is larger than the diameter of the fixed plate. A second placement slot is provided on the bottom of the housing on one side of the first placement slot. A pipe clamp for mounting the output head is installed in the second placement slot.

[0022] The diameter of the first placement slot must ensure that the plug-in block can be inserted into the slot. When transporting or when the laser is not in use, remove the fourth and fifth bolts, separate the fixing plate from the plug-in block, and remove it. First, wrap the optical fiber around the outside of the connecting post, and clamp the output head into the pipe clamp. Then, fix the fixing plate to the plug-in block with the fifth bolt. The fourth bolt further tightens the fixing plate, limiting the optical fiber and preventing it from falling out. Tighten the fourth bolt, push the plug-in block inward, and push the plug-in block upward until the bottom surface of the fixing plate is flush with the bottom surface of the housing. The square packaging design can better secure the equipment and reduce the risk of damage due to vibration or collision during transportation. The storage of the optical fiber and output head can effectively prevent physical damage such as collision, squeezing, and friction, ensuring the integrity of the optical fiber and output head during transportation. When installing and using the laser with production equipment, remove the fourth and fifth bolts, separate the fixing plate from the plug-in block, and remove the optical fiber and output head from the first... After being removed from the first and second placement slots, the plug-in block is fixed to the fixing plate by the fifth bolt. The fixing plate is fixed on the production equipment or other platform. The connecting column is plugged into the plug-in block, and the elastic force of the third spring pushes the top plate against the plug-in block for fixation, and positions the fixing plate outside the first placement slot, so that there is a certain gap between the shell and the production equipment. This can prevent the vibration generated during the operation of the production equipment from causing friction between the shell and the production equipment, which would damage the shell surface. The elastic force of the third spring also plays a shock-absorbing role in the process of the top plate pressing against the plug-in block. When it is necessary to repair the laser, simply move the connecting column to one side and pull it out from the plug-in block. Not only is it convenient to operate without the need for additional tools, but it also avoids the problem of stripping when the laser is fixed with bolts during disassembly. With the cooperation of the connecting component and the fixing component, it is not only convenient for fiber storage, but also easy to disassemble. At the same time, it prevents the shell from shifting easily when placed directly, and also reduces vibration.

[0023] Furthermore, the fixing plate has two first fixing holes with an arc-shaped structure, and the fixing plate between the two first fixing holes has multiple second fixing holes. The second fixing holes are waist-shaped holes, and a sixth bolt for fixing with other equipment is provided in both the first fixing holes and the second fixing holes.

[0024] During installation, align the mounting plate with the mounting position, select a suitable position on the first and / or second mounting holes, and fix the mounting plate to other equipment or platforms using the sixth bolt. Then, insert the connecting post at the bottom of the housing into the plug block. The first and second mounting holes allow for flexible selection of the appropriate mounting position according to the actual situation.

[0025] Furthermore, a filter screen for filtering the air supplied by the first cooling fan is installed between the right inner wall of the housing and the first cooling fan. A limiting groove for inserting and removing the filter screen is provided on the housing, and a fixing cover for limiting the filter screen is closed on the top of the limiting groove.

[0026] The second cooling fan has an upward-facing mounting frame on its left side housing. A dustproof plate is installed inside the mounting frame. A mounting slot for inserting and removing the dustproof plate is provided on the inner side of the mounting frame. A ventilation opening is provided on the dustproof plate. An adjustment hole is provided on the dustproof plate above the ventilation opening. A seventh bolt is installed in the adjustment hole.

[0027] The upper end of the limiting groove is open, making it easy to insert and remove the filter screen. The fixing cover can limit the filter screen. The adjustment hole is an oblong hole in the vertical direction. When the second cooling fan is working, the ventilation port is aligned with the air outlet of the second cooling fan to facilitate the exhaust of internal air. When the second cooling fan is not working, the dustproof plate is moved down to make the ventilation port and the air outlet of the second cooling fan staggered to prevent external dust from entering the housing.

[0028] Furthermore, a fiber optic plate for mounting auxiliary devices is horizontally arranged below the mounting plate, and both ends of the fiber optic plate are fixed to corresponding supports.

[0029] The left end of the fiber optic cable is fixed to the left support, and the right end is fixed to the right support. The fiber optic cable allows for the unified layout of auxiliary components such as optical fibers, facilitating installation. Furthermore, the cable is fixed between the two supports, which facilitates heat dissipation for both the first and second cooling fans.

[0030] Furthermore, a side cover is installed on the right side of the housing of the first cooling fan, and an air inlet is opened on the side cover. A protective cover is installed on the housing at the output interface.

[0031] Protective covers and side covers further enhance the seal and reduce dust entering the housing.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] Auxiliary components include optical fibers, pump strippers, optical power components, red light components, wavelength division multiplexers, reverse light absorption devices, forward beam combiners, reverse beam combiners, backlight strippers, gratings, constant voltage power supplies, and main control boards. The pump source and auxiliary components are used to generate laser light and output after laser processing. The fixing components are used to fix pump sources of different sizes, thereby adapting to the installation of different types of pump sources. This avoids the situation where the pump source cannot be directly installed on the mounting plate when the external dimensions of the new pump source are significantly different from those of the original pump source. The air-cooling system can evenly dissipate heat inside the housing, thereby improving the overall cooling efficiency. Attached Figure Description

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0054] Example

[0055] The 980nm laser described in this embodiment, which is easy to install, is implemented using the following scheme:

[0056] like Figure 2 ,Figure 3 and Figure 18 As shown in Figure 1 and Figure 18 , a housing 14 with openings at the top and rear sides is formed by bending and welding high-strength and lightweight plates such as stainless steel or aluminum alloy. As Figure 1 and Figure 18 shown, through holes are opened on the right side of the housing 14, and three first cooling fans 9 are installed, and the specific number is determined according to needs; as Figure 1 shown, on the inner wall on the right side of the housing 14, at the left side of the first cooling fan 9 as Figure 13 shown, a rectangular groove is opened as a limiting groove, the top of the limiting groove is open, and a filter net 8 is inserted downward; as Figure 1 , Figure 5 and Figure 13 shown, a fixed cover 7 is installed on the top of the right side wall of the housing 14, and a notch corresponding to the inner structure of the fixed cover 7 is opened on the housing 14; as Figure 13 shown, the fixed cover 7 is arranged in a "冂" - shaped structure with both front and rear ends bent, and semi - cylindrical blocks are fixed on the inner side walls of the vertical parts at both ends of the fixed cover 7, and semi - elliptical protrusions are fixed on the outer side walls as Figure 5 shown. As Figure 1 and Figure 5 shown, a side cover 10 for protecting the first cooling fan 9 is installed on the outer side wall on the right side of the housing 14; as Figure 15 shown, ventilation holes are opened on the side cover 10. As Figure 1 and Figure 14 shown, a rectangular through - hole is opened on the left side of the housing 14 to install a second cooling fan 26, as Figure 6 shown, an installation frame 25 with a main structure of "凵" - shaped is fixed on the outer side wall on the left side of the housing 14, installation grooves are opened on the inner sides of the two vertical parts, and a dust - proof plate 24 is inserted into the installation grooves. The dust - proof plate 24 is evenly spaced with multiple rectangular - shaped through - holes opened from top to bottom as ventilation holes 29, as Figure 7 shown, the ventilation holes 29 and the air inlets of the second cooling fan 26 are arranged in a vertically staggered manner to achieve dust prevention; as Figure 6 shown, a kidney - shaped hole is vertically opened at a position near the top of the dust - proof plate 24 as an adjustment hole 30, the distance between the upper and lower ends of the kidney - shaped hole is the same as the distance between the ventilation holes 29 on the dust - proof plate 24, and a seventh bolt 23 is inserted through the kidney - shaped hole of the dust - proof plate 24 and is in threaded fit connection with the housing 14.

[0057] As Figure 4As shown, a groove is stamped, deformed or cut and welded at the center of the bottom of the housing 14 as the first placement groove 20. A groove with a cuboid structure is stamped and deformed on the right side of the first placement groove 20 as the second placement groove 22. Two groups of pipe clamps 12 are installed at intervals before and after in the second placement groove 22. The pipe clamp 12 is an existing technology, and the U-shaped elastic pipe clamp is adopted in this solution.

[0058] As Figure 9 shown, a connection component 28 is arranged in the first placement groove 20; the connection component 28 is composed of a connection column 2801, a third spring 2802 and a top plate 2803. As Figure 9 and 12 shown, the connection column 2801 has a frustum structure, and its diameter needs to be greater than the minimum diameter that the optical fiber 15 can bend. The upper end of the connection column 2801 is fixed in the first placement groove 20.

[0059] As Figure 9 shown, a groove with a "convex" - shaped cross - section is opened inward on the right - hand side wall of the connection column 2801. The lower - half groove is used as a slot, and second sliding grooves 2804 in the up - and - down sliding direction are opened on the left - and - right side walls of the upper - half groove.

When the third spring 2802 is in a free state, the lower end of the third spring 2802 is located below the circular hole; a threaded hole penetrating through to the internal groove is opened at the bottom of the connection column 2801.

[0060] Manufacture the fixing component 21.

[0061] As Figure 4 shown, the fixing disk 2101 has a disc structure. Two sections of waist - shaped counter - sunk holes curved along the circumference are symmetrically opened at the outer wall near the circumference on the fixing disk 2101 as the first fixing holes 2102; two sections of horizontal waist - shaped counter - sunk holes are symmetrically opened at intervals before and after between the two first fixing holes 2102 as the second fixing holes 2105, and a sixth bolt 2108 is arranged in the first fixing holes 2102 and the second fixing holes 2105. As Figure 9 shown, a counter - sunk hole is opened at the center of the fixing disk 2101. On the top surface of the fixing disk 2101, a rectangular positioning block 2107 is fixed on the right side of the central counter - sunk hole, and a counter - sunk hole penetrating through the positioning block 2107 is opened from the bottom of the fixing disk 2101. The inserting block 2106 has an inverted "L" - shaped structure. A positioning groove corresponding to the positioning block 2107 is opened at the bottom of the vertical part of the inserting block 2106, and a threaded hole is machined in the positioning groove, and a fifth bolt 2104 is threadedly engaged in the threaded hole.

[0062] The positioning groove of the plug-in block 2106 is fitted onto the positioning block 2107, and the thread of the fifth bolt 2104 passes through the fixing plate 2101 and is fixed to the plug-in block 2106. The plug-in block 2106 is inserted into the connecting post 2801. Figure 9 As shown, the screw of the fourth bolt 2103 is passed through the countersunk hole at the center of the fixing plate 2101 and fixed to the threaded hole of the connecting column 2801. The sixth bolt 2108 is as follows. Figure 4 As shown, it is inserted into the first fixing hole 2102 for limiting, and the fourth bolt 2103 and the sixth bolt 2108 can be the same type.

[0063] like Figure 1 and Figure 18 As shown, two L-shaped supports 11 are symmetrically installed on the side wall of the bottom inside the housing 14. The supports 11 have rectangular through holes that connect the left and right sides. A fiber optic plate 16 is detachably installed between the two supports 11.

[0064] like Figure 15 and 18 As shown, the fiber optic strip 16 is a rectangular plate structure with fiber optic slots on the top surface. It also houses auxiliary components such as a pump stripper, optical power assembly, red light assembly, wavelength division multiplexer, reverse light absorption device, forward beam combiner, reverse beam combiner, backlight stripper, grating, constant voltage power supply, and main control board. Refer to existing laser structures for details. Figure 18 As shown, an output interface 18 is installed on the left front end of the fiber optic cable 16. The fiber optic cable 16 is detachably installed at the corner of the support 11.

[0065] like Figure 1 and Figure 14 As shown, the mounting plate 17 of the square plate structure is installed on the inner side of the two supports 11 via a telescopic slide rail 6 with a locking function. The telescopic slide rail 6 is a known prior art technology, such as a hardware device used to realize the reciprocating movement of the load-bearing component in a linear direction. It is widely used in furniture, industrial machinery, logistics and railway fields. It mainly consists of a fixed guide rail and a movable rotor. The slide rail is extended by removing the stop bolt. Multiple sets of limiting blocks 27 are fixed horizontally at the middle position of the top of the mounting plate 17. The specific number depends on the usage requirements and the number of pump sources 3. Each set of limiting blocks 27 consists of two blocks spaced back and forth. The left end of the two limiting blocks 27 is inclined inward and the right end is inclined outward. Multiple first fixing components 4 are installed horizontally at intervals on the mounting plate 17 on both sides of each set of limiting blocks 27. The specific number corresponds to the limiting blocks 27.

[0066] The specific composition of the first fixing component 4 is as follows: Figure 11 and Figure 16As shown; including support block 401, the main body of support block 401 is a rectangular block structure, the lower half of which has a cable tray 405 with an opening facing the inside of the mounting plate 17 and a "U" shaped structure, and a rectangular notch is opened at the top of the inner end, and two threaded holes are machined at intervals in the rectangular notch, and bolts are installed in the threaded holes with threaded engagement.

[0067] It also includes a first fixing block 402, which is a right-angled trapezoidal structure. A countersunk hole is formed on the top surface of the first fixing block 402, corresponding to the position of the threaded hole in the notch on the support block 401. The bolt in the threaded hole passes through the countersunk hole and extends into the threaded hole, fixing the first fixing block 402 and the support block 401 together. A trapezoidal first slider 406 is fixed to the inclined surface on the right side of the first fixing block 402. The first slider 406 is rounded. A first threaded countersunk hole 409 is formed obliquely on the first slider 406, with the inclination angle being the same as the angle of the inclined surface of the first fixing block 402. A first spring 407 is independently placed in the countersunk head of the first threaded countersunk hole 409. The first fixing component 4 also includes a first pressure block 404. The main structure of the first pressure block 404 is a block structure with a trapezoidal cross-section. A groove is opened on the inclined surface of one end of the first pressure block 404 to slide up and down with the first slider 406. A first countersunk hole 408 is opened on the top surface of the first pressure block 404 and extends through the groove. The inclination angle is the same as the angle of the inclined surface of the first pressure block 404. The screw of the second bolt 403 passes through the first countersunk hole 408 and the first spring 407 and then extends into the first threaded countersunk hole 409 for internal thread connection. A rectangular notch is opened at the bottom of the inclined surface of the other end of the first pressure block 404 for pressing the pump source 3. This notch is a limiting port.

[0068] The second fixing component 5 is manufactured; the second fixing component 5 includes a second pressure block 501, a third bolt 502, a second fixing block 503, a second slider 504, and a second spring 505.

[0069] like Figure 10 and Figure 17As shown, the second fixing block 503 has an isosceles trapezoidal structure, and the angle of its inclined surface is the same as the inclination angle of the inclined surface of the first fixing block 402. The two inclined surfaces of the second fixing block 503 symmetrically fix the second slider 504. The second slider 504 has a second threaded countersunk hole 507 machined on it, and a second spring 505 is placed in the countersunk part of the second threaded countersunk hole 507. The structure and position of the second slider 504 are the same as those of the first slider 406. The second pressure block 501 is fitted on the second slider 504. The structure of the second pressure block 501 is the same as that of the first pressure block 404, and it has a second countersunk hole 506. The two second pressure blocks 501 are centrally symmetrical. The third bolt 502 passes through the second countersunk hole 506 and the second spring 505 is threadedly engaged with the threaded section of the second threaded countersunk hole 507. Two countersunk holes are opened at intervals on the top surface of the second fixing block 503. The second fixing block 503 is fixed to the mounting plate 17 by bolts at these countersunk holes. The second fixing block 503 is located between the limiting block 27 and the first fixing component 4. The second fixing components 5 located at both ends are only fitted with the inner second pressure block 501.

[0070] like Figure 10 As shown, the pump source 3 is placed between the first fixing component 4 and the limiting block 27. Tightening the second bolt 403 compresses the first spring 407, causing the first pressure block 404 to move obliquely downwards along the inclined surface of the first fixing block 402, thus fixing the pump source 3 along its length. Tightening the third bolt 502 compresses the second spring 505, causing the second pressure block 501 to move obliquely downwards along the inclined surface of the third bolt 502, thus fixing the pump source 3 along its width. The optical fiber of the pump source 3 is fixed inside each set of limiting blocks 27; the power cable of the pump source 3 is as follows... Figure 11 The wires are gathered into the cable tray 405 as shown.

[0071] Fabricate flow guide component 2, which includes flow guide plate 201, air inlet 202, adjusting plate 203, sliding block 204, fixing strip 205, gourd hole 206 and first bolt 207.

[0072] like Figure 3 and 18 As shown, the guide plate 201 is a rectangular plate structure. Multiple gourd-shaped holes 206 are first opened at intervals at both ends. A first bolt 207 is placed inside each gourd-shaped hole 206. Then, the left end is bent at a 90-degree angle, and the right end is bent. Fixing strips 205 are fixed to both the front and rear sides of the guide plate 201. Figure 3 and Figure 8As shown, a plurality of sliding grooves are spaced from left to right on the inner side of the fixed bar 205. An adjusting plate 203 with a square plate structure is placed in each sliding groove in a left-right sliding fit. A sliding block 204 with a "convex" shape is installed on the top surface of the adjusting plate 203. Air inlets 202 penetrating through the adjusting plate 203 and the deflector plate 201 are provided on both the deflector plate 201 and the adjusting plate 203. The position of the air inlet 202 on the deflector plate 201 is above the pump source 3. The screw rod of the first bolt 207 in the gourd hole 206 on the left passes through the gourd hole 206 at the left end of the deflector plate 201 and is fixed on the inner wall of the left side of the housing 14. The first bolt 207 in the gourd hole 206 on the right passes through the gourd hole 206 on the right side of the deflector plate 201 and is fixed on the top of the right support 11.

[0073] An inverted "L" - shaped top cover 1 is installed on the top surface of the housing 14, corresponding to the opening of the housing 14. A first sliding groove 101 for sleeving the sliding block 204 is provided on the top cover 1. The sliding block 204 is arranged in a left - right sliding fit with the first sliding groove 101, and the upper end of the sliding block 204 is above the first sliding groove 101.

[0074] As Figure 2 and Figure 12 shown, a through - hole with a square structure is opened on the front of the housing 14, corresponding to the output interface 18. As Figure 11 shown, a protective cover 19 with a "冂" - shaped structure is installed on the inner side wall of the housing 14 at the position of the through - hole with a square structure.

[0075] As Figure 2 and Figure 18 shown, first, a wire trough is obliquely opened on the front of the housing 14 from the output interface 18 to the bottom edge of the housing 14. Then, as Figure 4 shown, a wire trough connecting to the first placement groove 20 is opened along the bottom edge of the housing 14, and a wire trough connecting the first placement groove 20 to the second placement groove 22 is opened; the bending angle of the wire trough needs to be greater than the bending angle of the optical fiber 15. The bending angle of the optical fiber 15 needs to be determined according to the type of the optical fiber used. One end of the optical fiber 15 is connected to the output interface 18, and the other end is connected to an output head 13; the output head 13 is the output part of the laser, which is a known prior art and consists of two parts: a beam expander and a collimator.

[0076] The usage instructions of the above - mentioned technical solution are as follows:

[0077] When it is necessary to store the optical fiber 15 and the output head 13 during transportation, the following operations are carried out:

[0078] As Figure 1 、 Figure 4 and Figure 9As shown, remove the fourth bolt 2103 and the fifth bolt 2104, and separate and remove the fixing plate 2101 from the plug block 2106. First, connect the starting section of the optical fiber 15 as shown. Figure 2 and Figure 4 As shown, place it into the cable trays on the front and bottom surfaces of housing 14, and then... Figure 1 and 9 As shown, the middle section of optical fiber 15 is wound around the outer wall of connecting post 2801, and the end section of optical fiber 15 is placed in the cable tray connecting the first placement slot 20 and the second placement slot 22. The output head 13 is clamped in the tube clamp 12. Figure 9 As shown, the fixing plate 2101 is fixed to the plug block 2106 by the fifth bolt 2104, and the fourth bolt 2103 is reinstalled to limit the optical fiber 15 and prevent it from falling off. Tightening the fourth bolt 2103 pushes the plug block 2106 upward, making the bottom surface of the fixing plate 2101 flush with the bottom surface of the housing 14. The square packaging design can better secure the equipment and reduce the risk of damage due to vibration or collision during transportation. The storage of the optical fiber 15 and the output head 13 can effectively prevent physical damage such as collision, squeezing and friction, ensuring the integrity of the optical fiber 15 and the output head 13 during transportation.

[0079] When lasers are installed and used with production equipment:

[0080] like Figure 1 , Figure 4 and Figure 9 As shown, after removing the fourth bolt 2103 and the fifth bolt 2104, the fixing plate 2101 and the plug-in block 2106 are separated and removed. The optical fiber 15 and the output head 13 are then taken out from the first placement slot 20 and the second placement slot 22. The plug-in block 2106 is then removed and fixed to the fixing plate 2101 by the fifth bolt 2104. The fixing plate 2101 is then fixed to the production equipment by the sixth bolt 2108, which passes through the corresponding position of the first fixing hole 2102 or the second fixing hole 2105 according to usage requirements. For example... Figure 9 As shown, the connecting post 2801 is inserted into the plug-in block 2106. The third spring 2802 pushes the top plate 2803 down to fix the plug-in block 2106, and the bottom surface of the fixing plate 2101 is located outside the first placement groove 20, so that the housing 14 is a certain gap from the production equipment. The gap can prevent the vibration generated during the operation of the production equipment from causing friction between the housing 14 and the production equipment, which would cause damage to the surface of the housing 14. The third spring 2802 also plays a certain role in shock absorption during the support process. When the laser needs to be repaired, simply move the connecting post 2801 to the left to remove it from the plug-in block 2106. Not only does it not require the use of additional tools and is easy to operate, but it also avoids the problem of stripping the threads during disassembly, which is common when using bolts to fix the laser.

[0081] The heat dissipation process of the laser is as follows:

[0082] When the laser is working, such as Figure 6 As shown, first lift the dust cover 24 so that the through holes on the dust cover 24 are aligned with the air vents of the second cooling fan 26, and then lock the dust cover 24 with the seventh bolt 23; Figure 3 As shown, by moving the sliding block 204 left and right to adjust the position of the adjusting plate 203, the air inlet 202 on the adjusting plate 203 is aligned with the air inlet 202 on the guide plate 201 or the offset position is adjusted to adjust the air volume of the air inlet 202.

[0083] like Figure 1 and Figure 7 As shown, the first cooling fan 9 and the second cooling fan 26 are activated. The first cooling fan 9 blows air into the housing 14, and the second cooling fan 26 exhausts the air into the housing 14. Figure 1 The airflow shown enters the cavity formed between the fiber optic disc 16, the mounting plate 17, the top cover 1, and the flow guiding assembly 2. The airflow entering the cavity between the fiber optic disc 16 and the mounting plate 17 cools the base plate of the mounting plate 17, the fiber optic disc 16, and the auxiliary devices mounted on the fiber optic disc 16. The airflow in the cavity between the flow guiding assembly 2 and the top cover 1 enters the cavity between the flow guiding assembly 2 and the mounting plate 17 through multiple air inlets 202, cooling the corresponding pump sources 3. The airflow at the air inlets 202 can be adjusted by moving the sliding block 204 left and right. When the laser stops, as... Figure 6 and Figure 7 As shown, the dustproof plate 24 is moved downwards and locked to prevent dust from entering the housing 14.

[0084] The airflow guide assembly 2 can adjust the airflow by adjusting the position of the air inlet 202 on the regulating plate 203, thereby effectively controlling the airflow direction and enabling the cooling air to precisely cool each pump source 3, thus improving the overall cooling efficiency.

[0085] The adjustable design of the air inlet 202 allows the laser to flexibly adjust the cooling air volume and speed according to different working conditions and environmental requirements, thereby better adapting to various working environments.

[0086] When the laser needs to be replaced after prolonged operation, the following steps should be taken:

[0087] Reverse the first cooling fan 9 to exhaust air outwards, preventing dust from the filter 8 and its surrounding area from entering the interior when the filter 8 is replaced. Figure 13 As shown, pry open the semi-elliptical protrusions on both sides of the fixing cover 7 to remove the fixing cover 7, and then you can insert and remove the filter screen 8 for easy replacement.

[0088] When the laser malfunctions or the pump source 3 is damaged, resulting in performance degradation and requiring maintenance, the following procedures should be performed:

[0089] First Figure 15 As shown, remove the top cover 1; then... Figure 3 As shown, after loosening the first bolt 207, push the guide plate 201 backward so that the large hole of the gourd hole 206 aligns with the first bolt 207. Then, the guide plate 201 can be lifted and removed directly. The gourd hole 206 is designed for easy disassembly; simply loosening the bolt completes the installation or disassembly of the guide plate 201. Finally, disconnect the connecting wires between the pump source 3 and the auxiliary devices on the fiber optic plate 16, and then slide the mounting plate 17 outward via the telescopic slide rail 6. This allows for the inspection and replacement of the auxiliary devices on the fiber optic plate 16. Replacing the pump source 3 only requires opening the corresponding first fixing component 4 and second fixing component 5 for convenient replacement. The installation distance between the first fixing component 4 and the second fixing component 5 has a certain adjustable range, increasing flexibility. This flexibility allows for the selection of a suitable pump source 3 according to application requirements, thereby optimizing the overall performance of the laser system. It avoids the problem that the pump source cannot be directly installed on the mounting plate 17 when the dimensions of the new pump source 3 differ significantly from the original pump source 3. After the inspection and replacement are completed, as shown... Figure 14 As shown, push the mounting plate 17 back, connect the wires, and install the flow guide assembly 2 and the top cover 1 in sequence.
