Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically a laser welding assembly for textile equipment. Background Technology

[0002] Textile equipment is the core production equipment of the textile industry, encompassing various types of equipment throughout the entire process of spinning, weaving, dyeing, and finishing. Key load-bearing components such as frames, wall panels, transmission supports, and guide rail mounting bases often utilize steel plate splicing structures. The welding quality of these components directly determines the equipment's operational accuracy, stability, and service life. Currently, laser welding, with its advantages of low heat input, minimal welding deformation, and high production efficiency, is widely used in the welding processing of metal parts in textile equipment. Laser welding assemblies are the core functional integration units in automated welding systems, primarily consisting of three core parts: a welding robot, a welding table, and tooling fixtures. Through preset programs, they achieve automated splicing and welding of metal parts.

[0003] However, existing laser welding components for textile equipment still have many shortcomings. The welding process lacks a dedicated fume extraction device, resulting in large amounts of welding slag and fumes that disperse freely, polluting the workshop environment, harming operators' health, and adhering to the surface of optical components in the welding head, causing laser energy attenuation and reduced welding quality. After welding, the temperature of the weld and heat-affected zone can reach hundreds of degrees Celsius, with slow natural cooling. This not only easily leads to coarse weld grains and reduced mechanical properties but also prevents timely unloading and transfer of workpieces due to prolonged high temperatures, significantly reducing production efficiency. Furthermore, the high temperature of the workpieces can easily cause operator injuries. Burns are a risk; in addition, the complex environment inside welding plants makes it easy for lubricating grease, rust inhibitors and other oil stains to accumulate on the surface of equipment. Under the influence of equipment operation, workpiece transfer and ventilation airflow, the oil stains will be dispersed into the air in the form of oil mist and dust. When the equipment is idle for a long time, this oily dust will directly adhere to key parts such as the optical lens and light output port of the welding gun, which will not only block the laser beam path and reduce the light output efficiency, but also form hard-to-clean scorch marks due to high temperature during welding, resulting in uneven light spots and insufficient penetration. At the same time, the accumulation of dust and oil will also accelerate the aging and wear of optical components, greatly increasing the equipment failure rate and maintenance costs.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, the laser welding assembly for textile equipment of the present invention includes a base 1, a welding component on the base 1, and a purification structure 2 on the welding table 13 of the welding component. The purification structure 2 includes an adjustment seat 201 slidably connected to the welding table 13 and a purification component on the adjustment seat 201. The purification component is used to purify the smoke and dust. The purification component is provided with an air guide. A driving structure 4 is provided between the welding table 13, the purification component and the air guide. The driving structure 4 is used to drive the air guide to swing back and forth.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, the welding component includes a welding table 13, a robotic arm base 8, a robotic arm 9, a connecting seat 10, and a welding gun 11. The welding table 13 is rotatably connected to the base 1, the robotic arm base 8 is mounted on the base 1, and the robotic arm 9 is rotatably connected to the robotic arm base 8. The controller 12 calls a pre-written welding program specifically for textile machine frames, controlling the robotic arm base 8 to drive the multi-joint robotic arm 9 to perform six-degree-of-freedom spatial motion. The connecting seat 10 simultaneously drives the welding gun 11 to position itself to the weld start point. The laser generator inside the welding gun 11 is activated to generate a high-energy laser beam, which, after being focused by the optical system, acts on the joint of the steel plate to be welded on the textile machine frame. The welding process involves melting the plate material locally to form a stable molten pool. Simultaneously, the robotic arm 9 moves at a constant speed according to a preset welding speed and trajectory, driving the welding gun 11 to continuously advance along the weld seam. This causes the molten pool to solidify sequentially, forming a continuous and dense weld seam. The welding table 13 can also adjust its tilt angle via a matching motor to adapt to the welding requirements of weld seams in different orientations. During the welding process, the controller 12 adjusts the laser output power and welding speed in real time according to preset parameters to adapt to the welding requirements of steel plates of different thicknesses, ensuring uniform weld depth and smooth weld formation.

[0024] Specifically, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the purification components include a purification box 202, an activated carbon box 203, a negative pressure fan 205, and a filter screen 206. The purification box 202 is fixedly connected to the adjusting seat 201, and the activated carbon box 203 and the filter screen 206 are detachably connected to the purification box 202. The negative pressure fan 205 is installed inside the purification box 202. The first driving component 207 drives the first lead screw 204 to rotate, and the screw drives the adjusting seat 201 to slide along the guide rail of the welding table 13, so that the purification box 202 always moves synchronously with the welding position of the welding gun 11, ensuring the accuracy of fume collection. When the negative pressure fan 205 is started, it generates negative pressure, and the fume and slag generated during welding are collected under the action of negative pressure. Upon entering the purification chamber 202, welding slag is first intercepted by the filter screen 206 and falls into the collection hopper 208 under gravity for centralized collection. Harmful gases are further purified by passing through the filter screen 206 and activated carbon box 203 before being discharged, maintaining a clean working environment in the textile workshop. The collection hopper 208 is fixedly connected to the frame of the filter screen 206. The air guide includes a connecting shaft 209 and an air guide plate 210. Two connecting shafts 209 are fixedly connected to the purification chamber 202, and the air guide plate 210 is rotatably connected to the connecting shafts 209. A first lead screw 204 is rotatably connected to the welding table 13, and the adjusting seat 201 is threadedly connected to the first lead screw 204. The first drive component 207 is installed on the 3, and the first lead screw 204 is driven to rotate by the first drive component 207. The drive structure 4 includes a fixed rod 401 fixedly connected to the air guide plate 210 and a drive groove 402 provided on the fixed rod 401. A guide sleeve 405 is fixedly connected to the purification box 202. An adjusting rod 404 is slidably connected to the guide sleeve 405. Two drive shafts 403 are rotatably connected to the adjusting rod 404. The two drive shafts 403 are respectively in rolling cooperation with the two drive grooves 402. A connecting rod 406 is fixedly connected to the adjusting rod 404. A roller 407 is rotatably connected to the connecting rod 406. An installation device is fixedly connected to the welding table 13. Mounting plate 408, roller 407 rolls with mounting plate 408, mounting plate 408 is provided with inclined groove 409. During the movement of purification box 202, connecting rod 406 drives roller 407 to roll along inclined groove 409 on mounting plate 408, so that connecting rod 406 drives adjusting rod 404 to slide up and down along guide sleeve 405. Drive shaft 403 on adjusting rod 404 rolls in drive groove 402 of fixed rod 401, driving air guide plate 210 to swing back and forth around connecting shaft 209, dynamically expanding negative pressure adsorption range, capturing smoke and dust diffused in different directions, and improving overall purification efficiency. Inclined groove 409 is used to drive connecting rod 406 to move up and down.

[0025] Specifically, such as Figure 3 and Figure 4As shown, the purification box 202 is equipped with an installation structure 3. The installation structure 3 includes a fixed shaft 301 fixedly connected to the purification box 202 and a baffle 302 rotatably connected to the fixed shaft 301. The baffle 302 blocks and limits the activated carbon box 203 and the filter screen 206. Pulling the iron block 305 separates it from the slot 304 and the magnetic block 306. Rotating the baffle 302 180 degrees allows the activated carbon box 203 and the filter screen 206 to be quickly removed for replacement or cleaning, ensuring the continuous working capacity of the purification system. A fixed ring 303 is fixedly connected to the fixed shaft 301, and an iron block 305 is slidably connected to the baffle 302. The fixed ring 303 has two slots 304, and the iron block 305 engages with one of the slots 304. A magnetic block 306 is fixedly connected to the fixed ring 303, and the iron block 305 is attracted to one of the magnetic blocks 306.

[0026] Specifically, such as Figure 2 , Figure 6 and Figure 9 As shown, a cooling structure 5 is provided between the robotic arm 9, the robotic arm base 8, and the connecting seat 10. The cooling structure 5 includes a liquid storage tank 501 fixedly connected to the robotic arm 9 and a sealing cover 502 installed on the liquid storage tank 501. An installation pipe 506 is installed on the connecting seat 10, and a nozzle 507 is installed on the installation pipe 506. A delivery pump 505 is installed on the liquid storage tank 501. When the delivery pump 505 is started, the coolant in the liquid storage tank 501 is delivered to the installation pipe 506 through a hose, and finally sprayed by the nozzle 507 onto the weld and heat-affected zone to rapidly cool the welded area. Rapid cooling after welding can accelerate the solidification and shaping of the weld, facilitating subsequent rapid unloading and transfer. At the same time, it can significantly reduce the temperature of the welded area and prevent burns to operators when they come into contact with it. A stirring shaft 503 is rotatably connected to the sealing cover 502, and a stirring rod 504 is fixedly connected to the stirring shaft 503. During the rotation of the robotic arm base 8, the gear ring 508 fixed on the robotic arm base 8 and the first gear 509 on the stirring shaft 503 generate relative motion, driving the stirring shaft 503 to drive the stirring rod 504 to rotate automatically, continuously stirring the coolant in the storage tank 501, which can make the coolant uniformly mixed as a whole, avoiding temperature stratification and uneven solute in the medium in the tank, ensuring that the temperature and concentration of the sprayed cooling medium are consistent, and improving the stability and uniformity of welding cooling. The gear ring 508 is fixedly connected to the robotic arm base 8, the first gear 509 is fixedly connected to the stirring shaft 503, the mounting sleeve 510 is fixedly connected to the storage tank 501, and the mounting block 511 is fixedly connected to the sealing cover 502. The mounting block 511 is slidably connected to the mounting sleeve 510, and the second lead screw 512 is rotatably connected to the mounting block 511. The second lead screw 512 is threadedly connected to the mounting sleeve 510.

[0027] Specifically, such as Figure 2 , Figure 10 and Figure 11 As shown, the connecting seat 10 is provided with a protective structure 6. The protective structure 6 includes a mounting seat 601 fixedly connected to the connecting seat 10 and two mounting shafts 602 rotatably connected to the mounting seat 601. A mounting ring 603 is fixedly connected to one mounting shaft 602, and an adjusting ring 606 is rotatably connected to the other mounting shaft 602. Mounting rods 604 are fixedly connected to both the adjusting ring 606 and the mounting ring 603. Protective sleeves 605 are fixedly connected to the mounting rods 604. The two protective sleeves 605 protect the welding gun 11 and the nozzle 507 respectively. The transmission shaft 607 can be driven to rotate by the second driving member 610, which drives the second gear 608 to rotate. The second gear 608 simultaneously meshes with two third gears 609, causing the two mounting shafts 602 to rotate clockwise and counterclockwise respectively, driving the mounting rods 604 and the protective sleeves 605 to rotate, so that the protective sleeve 605 on the nozzle 507 side... 05 is fully open, and the protective sleeve 605 on one side of the welding gun 11 is closed to protect the non-light-emitting part of the welding gun 11 and prevent coolant from splashing and contaminating the optical elements of the welding gun 11. After the welding operation is completed, the second drive component 610 drives the transmission shaft 607 to rotate again, driving the two protective sleeves 605 to rotate to the front end of the welding gun 11 and the nozzle 507 respectively, to fully seal and protect the working ends of both, to prevent dust and oil from adhering to the optical elements and the nozzle 507, and to ensure the stable performance of the equipment when it is idle for a long time. The transmission shaft 607 is rotatably connected to the mounting base 601, and the second gear 608 is fixedly connected to the transmission shaft 607. The third gear 609 is fixedly connected to the mounting shaft 602. The second gear 608 and the third gear 609 mesh. The second drive component 610 is installed on the mounting base 601, and the transmission shaft 607 is driven by the second drive component 610.

[0028] Specifically, such as Figure 10 and 11 As shown, the adjusting ring 606 is fixed to the mounting shaft 602 via a limiting structure 7. The limiting structure 7 includes a limiting shaft 701 slidably connected to the adjusting ring 606 and a connecting ring 702 fixedly connected to the mounting shaft 602. The connecting ring 702 has two limiting holes 703. The limiting shaft 701 engages with one of the limiting holes 703. When it is necessary to adjust the angle of the mounting rod 604 on the adjusting ring 606 corresponding to the protective sleeve 605, the pressing ring 704 is pressed, which drives the limiting shaft 701 from the connecting ring 602. The ring 702 disengages from the limiting hole 703, and at the same time the tension spring 705 is compressed. At this time, the adjusting ring 606 can be rotated to adjust the angle of the corresponding protective sleeve 605. After the adjustment is completed, the pressing ring 704 is released, and the tension spring 705 rebounds, causing the limiting shaft 701 to be inserted into another limiting hole 703 to complete the fixation. The operation is flexible and convenient. The pressing ring 704 is fixedly connected to the limiting shaft 701. The pressing ring 704 is slidably connected to the adjusting ring 606, and the tension spring 705 is fixedly connected between the pressing ring 704 and the adjusting ring 606.

[0029] In use, the textile machine frame to be welded is first fixed to the welding table 13 using a tooling fixture. The controller 12 is electrically connected to all electrical components and controls the movement of each part. After the welding program is started, the controller 12 calls the pre-written welding program for the textile machine frame, controlling the robotic arm base 8 to drive the multi-joint robotic arm 9 to perform six-degree-of-freedom spatial movement. The connecting seat 10 simultaneously drives the welding gun 11 to be positioned at the weld start point. The laser generator inside the welding gun 11 is activated to generate a high-energy laser beam, which is focused by the optical system and acts on the joint of the steel plate to be welded on the textile machine frame, causing the plate to melt locally and instantaneously. A stable molten pool is formed, and the robotic arm 9 moves at a constant speed according to the preset welding speed and trajectory, driving the welding gun 11 to continuously advance along the weld seam, so that the molten pool solidifies in sequence to form a continuous and dense weld seam. The welding table 13 can also adjust the tilt angle through the matching motor to adapt to the welding requirements of weld seams in different directions. During the welding process, the controller 12 adjusts the laser output power and welding travel speed in real time according to preset parameters to adapt to the welding requirements of steel plates of different thicknesses, ensuring that the weld seam has uniform penetration and a smooth shape. During the welding process, the first driving component 207 (preferably a stepper motor) drives the first lead screw 204 to rotate, and the thread drives the adjusting seat 201. Sliding along the guide rail of the welding table 13, the purification box 202 always moves synchronously with the welding position of the welding gun 11, ensuring the accuracy of fume collection. The negative pressure fan 205 starts to generate negative pressure, and the fume and slag generated during welding enter the purification box 202 under the action of negative pressure. The slag is first intercepted by the filter screen 206 and falls into the collection hopper 208 for centralized collection under the action of gravity. Harmful gases are further purified by passing through the filter screen 206 and the activated carbon box 203 in sequence before being discharged, maintaining a clean working environment in the textile workshop. At the same time, during the movement of the purification box 202, the connecting rod 406 drives the roller 407 along the mounting plate 408. The sloping groove 409 rolls, causing the connecting rod 406 to drive the adjusting rod 404 to slide up and down along the guide sleeve 405. The drive shaft 403 on the adjusting rod 404 rolls in the drive groove 402 of the fixed rod 401, causing the air guide plate 210 to swing back and forth around the connecting shaft 209, dynamically expanding the negative pressure adsorption range, capturing smoke and dust diffused in different directions, and improving the overall purification efficiency. During routine maintenance, the iron block 305 is pulled to separate it from the slot 304 and the magnetic block 306, and the baffle 302 is rotated 180 degrees to quickly remove the activated carbon box 203 and the filter screen 206 for replacement or cleaning, ensuring the continuous working capacity of the purification system. Before welding, if the angle of the mounting rod 604 on the adjusting ring 606 corresponding to the protective sleeve 605 needs to be adjusted separately, press the pressing ring 704 to drive the limiting shaft 701 out of the limiting hole 703 of the connecting ring 702. At the same time, the tension spring 705 is compressed. At this time, the adjusting ring 606 can be rotated to adjust the angle of the corresponding protective sleeve 605. After the adjustment is completed, release the pressing ring 704. The tension spring 705 rebounds and drives the limiting shaft 701 to engage in another limiting hole 703 to complete the fixation. The operation is flexible and convenient. After the welding operation begins, the transmission shaft 607 can be driven to rotate by the second driving component 610 (preferably a servo motor), which drives the second gear 608 to rotate. The second gear 608 simultaneously interacts with two third... Gear 609 meshes, causing the two mounting shafts 602 to rotate forward and reverse respectively, driving the mounting rod 604 and protective sleeve 605 to rotate. This causes the protective sleeve 605 on the nozzle 507 side to fully open and the protective sleeve 605 on the welding gun 11 side to close, protecting the non-light-emitting parts of the welding gun 11 and preventing coolant from splashing and contaminating the optical elements of the welding gun 11. After the welding operation is completed, the second drive component 610 drives the transmission shaft 607 to rotate again, causing the two protective sleeves 605 to rotate to the front end of the welding gun 11 and the nozzle 507 respectively, providing full sealing protection for the working ends of both, preventing dust and oil from adhering to the optical elements and the nozzle 507, and ensuring the stable performance of the equipment when it is idle for a long time. After welding, the delivery pump 505 is started (a flexible hose can be installed between the outlet of the delivery pump 505 and the installation pipe 506, and a corresponding hose limiting ring is installed on the robotic arm 9), and the coolant in the storage tank 501 is delivered to the installation pipe 506 through the hose. Finally, it is sprayed onto the weld and heat-affected zone by the nozzle 507 to quickly cool the welded area. Rapid cooling after welding can accelerate the solidification and shaping of the weld, which is convenient for subsequent rapid unloading and transportation. At the same time, it can significantly reduce the temperature of the welded area and avoid burns to operators when they come into contact with it. The hose limiting rings set at intervals on the outer wall of the robotic arm 9 keep the delivery hose in place and prevent the hose from shaking, tangling, pulling and bending during the movement of the robotic arm, ensuring the smooth flow of the coolant delivery pipeline and extending the service life of the hose. During the rotation of the robotic arm 9 on the robotic arm base 8, it is fixed to the robotic arm base 8. The gear ring 508 on the upper part of the stirring shaft 503 and the first gear 509 on the stirring shaft 503 generate relative motion, driving the stirring shaft 503 to drive the stirring rod 504 to rotate automatically, continuously stirring the coolant in the storage tank 501. This ensures that the coolant is mixed evenly, preventing temperature stratification and uneven solute distribution in the medium inside the tank, ensuring that the temperature and concentration of the sprayed cooling medium are consistent, and improving the stability and uniformity of welding cooling. When it is necessary to add coolant or maintain the stirring rod 504, first rotate the second lead screw 512 to make the mounting block 511 slide upward along the mounting sleeve 510, driving the sealing cover 502 and the stirring shaft 503 to rise as a whole, so that the first gear 509 moves to the notch of the gear ring 508. At this time, the sealing cover 502 and the stirring shaft 503 can be directly removed from the storage tank 501. The operation is simple and quick, without the need to disassemble other related parts.
