Description

Technical Field

[0001] This invention relates to the technical field of arc spraying, specifically to a spraying device for the wall panel of a hot-dip galvanizing furnace nose. Background Technology

[0002] Hot-dip galvanizing is an important process for corrosion protection of steel materials. The furnace nose, as a key component in the galvanizing production line, is exposed to high-temperature, highly corrosive zinc vapor and splashing environment for extended periods. The performance of its inner wall protective coating directly affects the equipment's lifespan and operational stability. Arc spraying technology, with its advantages of high coating bonding strength and good resistance to high-temperature oxidation and corrosion, has become one of the mainstream processes for surface protection of the furnace nose wall panels.

[0003] Existing automated spraying equipment for large curved wall panels typically employs multi-axis robotic arms carrying spray guns, operating along preset tracks. However, significant shortcomings remain in practical applications: First, it's difficult to ensure absolute verticality or the theoretical orientation of the wall panel during clamping; even slight initial tilting can cause spray trajectory deviations, affecting coating uniformity. Second, with wall panel surfaces exhibiting complex curvature, traditional equipment struggles to maintain the optimal constant distance between the spray gun and the workpiece surface in real-time and with precision, resulting in uneven coating thickness. More importantly, the localized high heat generated during continuous spraying can easily accumulate thermal stress within the coating, inducing microcracks and severely impacting the long-term protective effect of the coating. These technical bottlenecks restrict further improvements in spraying quality and process automation.

[0004] Therefore, there is a need for a spraying equipment that can automate the spraying process and avoid micro-cracks in the coating caused by thermal stress. Summary of the Invention

A measuring device scans and analyzes the panel, driving the adjustment components to adjust the panel angle, ensuring the accuracy of the spraying reference surface. Subsequently, the system performs a high-precision contour scan of the panel surface, generating an accurate curved surface model. Based on this model, the control software employs a skip spraying strategy, dividing the spraying area into alternating segments and applying the coating in stages. This effectively disperses thermal stress and fundamentally reduces the risk of micro-cracks in the coating. During the spraying execution phase, the system pre-measures the spacing and learns the adaptive trajectory along the planned path, strictly replicating this trajectory during the actual spraying. This ensures that the spray gun maintains a constant optimal distance from the complex curved surface, guaranteeing the uniformity of the coating thickness. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of the present invention will now be described.

[0035] Please refer to the appendix for details. Figure 1 , 2As shown in Figures 3, 4, 7, 9, 11, and 12, in a preferred embodiment of the present invention, a hot-dip galvanizing furnace nose wall panel spraying equipment includes a wall panel clamping device 10, a three-axis positioning device 20 located on one side of the wall panel clamping device 10, an arc spraying device 30 symmetrically arranged on the execution end of the three-axis positioning device 20, and a panel measuring device 40. The wall panel clamping device 10 includes a base plate 11, a panel clamp 12 rotatably connected to the top of the base plate 11 at its bottom, and an adjusting component 13 disposed on the base plate 11 for adjusting the rotation angle of the panel clamp 12. The arc spraying device 30 includes an arc nozzle 31 disposed on the execution end of the three-axis positioning device 20, and an arc nozzle 31 disposed on the three-axis positioning device 20. A spacing measuring component 32 is located above the arc nozzle 31 and has an execution end. The spacing measuring component 32 includes an extension frame 321 mounted on the lifting frame 26, a protective baffle 322 at the end of the extension frame 321, a miniature electric cylinder 323 mounted on the top of the extension frame 321 and having its execution end penetrating through the extension frame 321, and a first distance sensor 324 mounted at the execution end of the miniature electric cylinder 323. The plate clamp 12 includes a rotating plate 121 rotatably connected to the base plate 11 via a rotating shaft at its bottom, an L-shaped support plate 122 mounted on the rotating plate 121, a plurality of L-shaped brackets 123 linearly arrayed on the L-shaped support plate 122, and the L-shaped support plate 122 slidably connected to the base plate 11. The 2-top structure includes multiple movable clamping plates 124, a first hydraulic cylinder 125 mounted on the rotating plate 121, and a power plate 126 mounted on the actuating end of the first hydraulic cylinder 125 and extending through the L-shaped support plate 122 to connect the multiple movable clamping plates 124; it also includes multiple second hydraulic cylinders 127 mounted on the outer wall of the L-shaped support plate 122, and an L-shaped clamping plate 128 mounted on the actuating end of the second hydraulic cylinders 127. The adjusting component 13 includes a drive ring 131 mounted at the bottom of the rotating plate 121, a guide rail 132 mounted on the base plate 11, a displacement block 133 slidably connected to the guide rail 132, and a drive column 134 mounted on the top of the displacement block 133 and slidably connected to the inner wall of the drive ring 131. The system includes a second lead screw 135 that is rotatably connected to the guide rail 132 and connected to the lead screw nut of the displacement block 133; a second worm gear ring 136 sleeved on the outer wall of the second lead screw 135; a second worm 137 disposed on the base plate 11 and meshing with the second worm gear ring 136; and a transmission motor 138 disposed on the base plate 11 for driving the second worm 137 to rotate. It also includes a control center 50 for a telecommunications connection panel clamping device 10, a three-axis positioning device 20, an arc spraying device 30, and a panel measuring device 40. The control center 50 includes a panel posture correction module 51, a panel measuring module 52, a jump spraying division module 53, a single spray distance setting module 54, and a spraying path replication module 55.

[0036] It should be noted that, in this embodiment, when spraying the hot-dip galvanizing furnace nose wall panel, the wall panel is first hoisted onto the panel clamp 12 by the hoisting equipment, and the panel clamp 12 clamps and fixes the wall panel.

[0037] After the plate clamp 12 fixes the wall panel, the plate posture correction module 51 triggers the three-axis positioning device 20 and the plate surface measuring device 40 to move from one end of the wall panel to the other end along the horizontal direction of the wall panel. During the movement, the plate posture correction module 51 obtains the movement information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45. By analyzing the change in the sum of the movement information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45, the plate body tilt information value is obtained. The plate posture correction module 51 triggers the adjustment component 13 according to the plate body tilt information until the plate body tilt information value is within the set range.

[0038] After the panel posture correction is completed, the panel surface measurement module 52 triggers the three-axis positioning device 20 and the panel surface measurement device 40 to move from the top of the panel to the bottom of the panel along the vertical direction of the panel. The panel surface measurement module 52 generates the panel surface curve information based on the measurement information of the displacement detection wheel 44, i.e. the two-dimensional coordinate Y value, the movement information of the Y-axis moving part 23, and the distance information measured by the distance measuring part 45, i.e. the two-dimensional coordinate X value.

[0039] The skip spraying division module 53 generates skip spraying information based on the surface curve information of the wall panel. The skip spraying information includes a first spraying segment and a second spraying segment arranged sequentially from top to bottom along the wall panel. The first spraying segment and the second spraying segment are staggered. The skip spraying method can effectively avoid microcracks caused by thermal stress. When generating the skip spraying information, only the Y value in the two-dimensional coordinate is set. The X value in the two-dimensional coordinate is adjusted by the spacing measurement component 32. When the same column of spraying segments of the wall panel is sprayed by arc spraying, the second spraying segment is sprayed after all the first spraying segments are sprayed in sequence.

[0040] The single spray distance setting module 54 sets the lengths of the first spray segment and the second spray segment;

[0041] Before arc spraying, the spacing measuring component 32 moves to the detection position, and the X-axis moving component 21 moves from the initial point to the end point according to the length of the spraying section. The spraying path copying module 55 receives the spacing information between the spacing measuring component 32 and the wall panel surface and triggers the Y-axis moving component 23 after analysis to keep the spacing information within the set range. During this process, the spraying path copying module 55 automatically records the movement amount information and movement time information of the Y-axis moving component 23 during the movement of the X-axis moving component 21.

[0042] During arc spraying, the X-axis moving component 21 is reset and moves from the initial point to the end point according to the length of the spraying section. The arc nozzle 31 sprays molten metal. The spraying path copying module 55 adjusts the Y-axis moving component 23 according to the movement amount information and movement time information to realize the spraying of the spraying section. This spraying method can ensure that the distance between the arc nozzle 31 and the wall panel remains unchanged.

[0043] Furthermore, when the plate clamp 12 is working, the first hydraulic cylinder 125 drives multiple movable clamping plates 124 to limit and clamp the bottom end of the wall panel through the power plate 126, and the second hydraulic cylinder 127 drives the L-shaped clamping plate 128 to descend to clamp the top of the wall panel. The wall panel is limited under the combined action of the movable clamping plate 124, the L-shaped clamping plate 128 and the L-shaped bracket 123.

[0044] Furthermore, when the adjusting component 13 is working, the actuator of the transmission motor 138 drives the second worm gear 137 to rotate. The second worm gear 137 drives the second lead screw 135 to rotate through the second worm wheel ring 136. The second lead screw 135 drives the displacement block 133 to move along the guide rail 132. When the displacement block 133 moves, it drives the drive column 134 to slide in the drive ring 131. The drive ring 131 drives the rotating plate 121 to rotate.

[0045] Furthermore, when the spacing measuring component 32 is working, the actuator of the miniature electric cylinder 323 drives the first distance sensor 324 to move out of the protective baffle 322. The first distance sensor 324 measures the distance information between itself and the outer wall of the wall panel and transmits it to the control center 50.

[0046] Please refer to the appendix for details. Figure 2 , 5 As shown in Figures 7, 8, and 10, in a preferred embodiment of the present invention, the three-axis positioning device 20 includes an X-axis moving component 21 disposed on the base plate 11, an X-axis moving plate 22 disposed on the execution end of the X-axis moving component 21, a Y-axis moving component 23 disposed on the X-axis moving plate 22, a Y-axis moving frame 24 vertically disposed on the execution end of the Y-axis moving component 23, a Z-axis moving component 25 disposed on the outer wall of the Y-axis moving frame 24, and a lifting frame 26 disposed on the execution end of the Z-axis moving component 25; the X-axis moving component 21 includes a X-axis moving plate 22 disposed on the base plate 11, an X-axis moving plate 22 disposed on the execution end of the X-axis moving plate ...3, a Y-axis moving plate 24 vertically disposed on the execution end of the Z-axis moving component 25, and a lifting frame 26 disposed on the execution end of the Z-axis moving component 25; the X-axis moving component 21 includes a X-axis moving plate 23 disposed on the base plate 11, an X-axis moving plate 24 disposed on the outer wall of the Y-axis moving frame 24, and a lifting frame 26 disposed on the execution end of the Z-axis moving component 25; the X-axis moving component 21 The base plate 11 has a first slide rail 211, a moving block 212 slidably connected to the first slide rail 211, a drive motor 213 on the base plate 11, a first lead screw 214 on the execution end of the drive motor 213 and connected to the moving block 212 by a lead screw nut, a first gear 215 sleeved on the outer wall of the first lead screw 214, and a first encoder 216 on the outer wall of the first slide rail 211 and whose detection end meshes with the first gear 215 through a gear; the X-axis moving component 21, the Y-axis moving component 23 and the Z-axis moving component 25 have the same structure.

[0047] It should be noted that in this embodiment, when the three-axis positioning device 20 is working, the working principle of the X-axis moving component 21, the Y-axis moving component 23, and the Z-axis moving component 25 is the same. Taking the X-axis moving component 21 as an example, the actuator of the drive motor 213 drives the first lead screw 214 to rotate, the first lead screw 214 drives the moving block 212 to move, and when the first lead screw 214 rotates, it can also drive the detection end of the first encoder 216 to rotate through the first gear 215. The first encoder 216 transmits the rotation angle information of the first lead screw 214 to the control center 50. The control center 50 can obtain the position information of the moving block 212 through the rotation angle and the set pitch information.

[0048] Please refer to the appendix for details. Figure 6 , 7 As shown in Figure 8, in a preferred embodiment of the present invention, the plate measuring device 40 includes an angle positioning component 41 disposed at the execution end of the three-axis positioning device 20, a positioning box 42 disposed at the execution end of the angle positioning component 41, a measuring frame 43 slidably connected at one end to the positioning box 42 and extending to the outside of the positioning box 42 at the other end, a displacement detection wheel 44 disposed at the end of the measuring frame 43, a distance measuring component 45 disposed inside the positioning box 42, and an elastic pressure measuring support component 46. The displacement detection wheel 44 includes a rotating shaft 441 rotatably connected to the measuring frame 43 and extending to the outside of the measuring frame 43, a roller 442 sleeved on the rotating shaft 441, a second gear 443 disposed at the end of the rotating shaft 441, and a second encoder 444 disposed on the outer wall of the measuring frame 43 and whose detection end meshes with the second gear 443 via the gear. The angle positioning component 41 includes a positioning tube 411 passing through the lifting frame 26 and rotatably connected to the lifting frame 26. The system includes a first electric cylinder 412 located inside the positioning tube 411, a first worm gear ring 413 sleeved on the outer wall of the positioning tube 411, a power motor 414 mounted on the lifting frame 26, and a first worm 415 located at the actuating end of the power motor 414 and meshing with the first worm gear ring 413. The actuating end of the first electric cylinder 412 is connected to the positioning box 42. The distance measuring component 45 includes a second distance sensor 451 located on the inner wall of the positioning box 42 and whose detection end passes through the elastic pressure measuring support component 46. The system also includes two industrial cameras 452 symmetrically arranged at both ends of the lifting frame 26. The elastic pressure measuring support component 46 includes a pressure sensor 461 located on the inner wall of the positioning box 42, a pressure plate 462 located at the detection end of the pressure sensor 461, and a spring 463 connected at one end to the pressure plate 462 and at the other end to the outer wall of the measuring frame 43. The second distance sensor 451 passes through the pressure sensor 461 and the pressure plate 462.

[0049] It should be noted that in this embodiment, the control center 50 receives the wall panel image information captured by the industrial camera 452 and triggers the three-axis positioning device 20 after analysis to move the arc spraying device 30 or the panel measuring device 40 to the initial position.

[0050] When the panel measuring device 40 is working, the angle positioning component 41 facilitates the adjustment of the angle of the positioning box 42. During the detection, the displacement detection wheel 44 abuts against the wall panel surface. The control center 50 receives the pressure information measured by the elastic pressure support component 46 and the distance information between the second distance sensor 451 and the measuring frame 43, and triggers the Y-axis moving component 23 according to the pressure information to ensure that the pressure information is within the set range.

[0051] The sum of the distance information and the movement information of the Y-axis moving component 23 is the two-dimensional coordinate X value;

[0052] Furthermore, when the angle positioning component 41 is working, the actuator of the power motor 414 drives the first worm gear 415 to rotate, the first worm gear 415 drives the positioning tube 411 to rotate through the first worm wheel ring 413, and the actuator of the first electric cylinder 412 drives the positioning box 42 to move.

[0053] Furthermore, when the displacement detection wheel 44 is working, the roller 442 rotates and drives the detection end of the second encoder 444 to rotate through the second gear 443. The control center 50 receives the angle information measured by the second encoder 444 and analyzes and obtains the displacement information based on the diameter of the roller 442.

[0054] Furthermore, when the elastic pressure support component 46 is working, the measuring frame 43 slides in the positioning box 42 and applies pressure to the pressure sensor 461 through the spring 463. The greater the compression of the spring 463, the greater the value of the pressure sensor 461.

[0055] The working principle of this invention is as follows:

[0056] When spraying the wall panel of the hot-dip galvanizing furnace nose, the wall panel is first hoisted onto the panel clamp 12 by hoisting equipment, and the panel clamp 12 clamps and fixes the wall panel.

[0057] After the plate clamp 12 fixes the wall panel, the plate posture correction module 51 triggers the three-axis positioning device 20 and the plate surface measuring device 40 to move from one end of the wall panel to the other end along the horizontal direction of the wall panel. During the movement, the plate posture correction module 51 obtains the movement information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45. By analyzing the change in the sum of the movement information of the Y-axis moving component 23 and the distance information measured by the distance measuring component 45, the plate body tilt information value is obtained. The plate posture correction module 51 triggers the adjustment component 13 according to the plate body tilt information until the plate body tilt information value is within the set range.

[0058] After the panel posture correction is completed, the panel surface measurement module 52 triggers the three-axis positioning device 20 and the panel surface measurement device 40 to move from the top of the panel to the bottom of the panel along the vertical direction of the panel. The panel surface measurement module 52 generates the panel surface curve information based on the measurement information of the displacement detection wheel 44, i.e. the two-dimensional coordinate Y value, the movement information of the Y-axis moving part 23, and the distance information measured by the distance measuring part 45, i.e. the two-dimensional coordinate X value.

[0059] The skip spraying division module 53 generates skip spraying information based on the surface curve information of the wall panel. The skip spraying information includes a first spraying segment and a second spraying segment arranged sequentially from top to bottom along the wall panel. The first spraying segment and the second spraying segment are staggered. The skip spraying method can effectively avoid microcracks caused by thermal stress. When generating the skip spraying information, only the Y value in the two-dimensional coordinate is set. The X value in the two-dimensional coordinate is adjusted by the spacing measurement component 32. When the same column of spraying segments of the wall panel is sprayed by arc spraying, the second spraying segment is sprayed after all the first spraying segments are sprayed in sequence.

[0060] The single spray distance setting module 54 sets the lengths of the first spray segment and the second spray segment;

[0061] Before arc spraying, the spacing measuring component 32 moves to the detection position, and the X-axis moving component 21 moves from the initial point to the end point according to the length of the spraying section. The spraying path copying module 55 receives the spacing information between the spacing measuring component 32 and the wall panel surface and triggers the Y-axis moving component 23 after analysis to keep the spacing information within the set range. During this process, the spraying path copying module 55 automatically records the movement amount information and movement time information of the Y-axis moving component 23 during the movement of the X-axis moving component 21.

[0062] During arc spraying, the X-axis moving component 21 is reset and moves from the initial point to the end point according to the length of the spraying section. The arc nozzle 31 sprays molten metal. The spraying path copying module 55 adjusts the Y-axis moving component 23 according to the movement amount information and movement time information to realize the spraying of the spraying section. This spraying method can ensure that the distance between the arc nozzle 31 and the wall panel remains unchanged.

[0063] When the plate clamp 12 is working, the first hydraulic cylinder 125 drives multiple movable clamping plates 124 to limit and clamp the bottom end of the wall panel through the power plate 126, and the second hydraulic cylinder 127 drives the L-shaped clamping plate 128 to descend to clamp the top of the wall panel. The wall panel is limited under the combined action of the movable clamping plate 124, the L-shaped clamping plate 128 and the L-shaped bracket 123.

[0064] When the adjusting component 13 is working, the actuator of the transmission motor 138 drives the second worm 137 to rotate. The second worm 137 drives the second lead screw 135 to rotate through the second worm wheel ring 136. The second lead screw 135 drives the displacement block 133 to move along the guide rail 132. When the displacement block 133 moves, it drives the drive column 134 to slide in the drive ring 131. The drive ring 131 drives the rotating plate 121 to rotate.

[0065] When the spacing measuring component 32 is working, the actuator of the miniature electric cylinder 323 drives the first distance sensor 324 to move out of the protective baffle 322. The first distance sensor 324 measures the distance information between itself and the outer wall of the wall panel and transmits it to the control center 50.

[0066] When the three-axis positioning device 20 is working, the working principle of the X-axis moving part 21, the Y-axis moving part 23 and the Z-axis moving part 25 is the same. Taking the X-axis moving part 21 as an example, the actuator of the drive motor 213 drives the first lead screw 214 to rotate. The first lead screw 214 drives the moving block 212 to move. When the first lead screw 214 rotates, it can also drive the detection end of the first encoder 216 to rotate through the first gear 215. The first encoder 216 transmits the rotation angle information of the first lead screw 214 to the control center 50. The control center 50 can obtain the position information of the moving block 212 through the rotation angle and the set pitch information.

[0067] The control center 50 receives the wall panel image information captured by the industrial camera 452 and, after analysis, triggers the three-axis positioning device 20 to move the arc spraying device 30 or the panel measuring device 40 to the initial position.

[0068] When the panel measuring device 40 is working, the angle positioning component 41 facilitates the adjustment of the angle of the positioning box 42. During the detection, the displacement detection wheel 44 abuts against the wall panel surface. The control center 50 receives the pressure information measured by the elastic pressure support component 46 and the distance information between the second distance sensor 451 and the measuring frame 43, and triggers the Y-axis moving component 23 according to the pressure information to ensure that the pressure information is within the set range.

[0069] The sum of the distance information and the movement information of the Y-axis moving component 23 is the two-dimensional coordinate X value;

[0070] When the angle positioning component 41 is working, the actuator of the power motor 414 drives the first worm 415 to rotate, the first worm 415 drives the positioning tube 411 to rotate through the first worm wheel ring 413, and the actuator of the first electric cylinder 412 drives the positioning box 42 to move.

[0071] When the displacement detection wheel 44 is working, the roller 442 rotates and drives the detection end of the second encoder 444 to rotate through the second gear 443. The control center 50 receives the angle information measured by the second encoder 444 and analyzes the displacement information based on the diameter of the roller 442.

[0072] When the elastic pressure support component 46 is working, the measuring frame 43 slides in the positioning box 42 and applies pressure to the pressure sensor 461 through the spring 463. The greater the compression of the spring 463, the greater the value of the pressure sensor 461.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
