Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an intelligent welding system and welding method for color-coated steel sheets. Background Technology

[0002] Color-coated steel sheet is a composite material with an organic coating on the surface of steel sheet. Because it combines the strength of steel sheet with the corrosion resistance and decorative properties of coating, it is widely used in construction, home appliances, transportation and other fields. In the processing and assembly of color-coated steel sheet, welding is the key process to achieve structural connection. Its welding quality directly affects the overall performance and service life of the product. With the development of intelligent manufacturing technology, higher requirements are put forward for the automation, precision and efficiency of color-coated steel sheet welding.

[0003] Welding color-coated steel sheets faces unique challenges: the coating is sensitive to temperature, and excessive heat during welding can easily cause the coating to discolor, peel off, or degrade in performance, affecting the product's appearance and corrosion resistance; at the same time, color-coated steel sheets have undulations in shape, and traditional welding equipment is difficult to stably adapt to the workpiece surface, which can easily lead to unstable weld spacing and affect weld quality.

[0004] Currently, in practical applications, the welding equipment for color-coated steel sheets in existing technologies lacks flexibility in adjusting the position of the welding mechanism. When faced with uneven surfaces on the color-coated steel sheet, it cannot adaptively maintain a stable welding distance, which easily leads to problems such as incomplete welding and over-welding. At the same time, there is a lack of effective thermal protection measures for the coating on both sides of the weld. The high heat generated by laser welding can easily diffuse into the coating area, causing coating damage and increasing subsequent repair costs. These defects limit the quality stability and production efficiency of color-coated steel sheet welding. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent welding system and method for color-coated steel sheets, which solves the problems of existing color-coated steel sheet welding equipment being unable to adaptively maintain a stable welding distance and lacking effective thermal protection measures.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a color-coated steel sheet intelligent welding system and welding method, including a frame, on which a color-coated steel sheet body to be welded is placed, a control box is fixedly installed on the frame, and an adjustment component is provided on the frame and a welding mechanism is connected through the adjustment mechanism;

[0008] The mounting block is equipped with a partition assembly, and the baffle included in the partition assembly can adapt to the shape of the color-coated sheet body. The partition reduces the thermal impact of the laser head on the coating on both sides of the color-coated sheet body when the laser head is welding the color-coated sheet body.

[0009] Furthermore, the adjustment assembly includes a first adjustment frame fixedly mounted on a frame, a second adjustment frame slidably mounted on the first adjustment frame, a first motor fixedly mounted on the first adjustment frame, a first adapter fixedly mounted on the first adjustment frame, a first adjustment belt for connecting the second adjustment frame being sleeved on the output shaft of the first motor and the adapter, the slider being slidably mounted on the second adjustment frame, a second motor fixedly mounted on the second adjustment frame, a second adapter fixedly mounted on the second adjustment frame, and a second adjustment belt for connecting the slider being sleeved on the output shaft of the second motor and the second adapter.

[0010] Furthermore, the telescopic assembly includes a pair of protrusions fixedly mounted on the extension plate, a first rotating rod rotatably mounted on the protrusions, a connector provided at the end of the first rotating rod away from the protrusions, a second rotating rod rotatably mounted on the connector, a mounting member provided at the end of the second rotating rod away from the connector, an abutment wheel rotatably mounted on the mounting member, and a double-ended screw threadedly connected to the pair of connectors, the double-ended screw having a pair of opposite threaded grooves.

[0011] Furthermore, the partition assembly includes a pair of mounting housings fixedly mounted on the mounting block, and two sets of symmetrically arranged positioning rods are fixedly mounted inside the mounting housings, with baffles slidably mounted on the positioning rods.

[0012] Furthermore, the bottom end of the baffle is inclined, and the inclined surfaces of the bottom ends of the symmetrical baffles are opposite. A movable groove is provided on the baffle, and a movable block is slidably installed in the movable groove.

[0013] Furthermore, the mounting housing has a cavity for the flow of coolant, and a pair of connecting parts communicating with the cavity are fixedly installed on the mounting housing. One of the connecting parts is fixedly installed with an inlet pipe, and the other connecting part is fixedly installed with an outlet pipe.

[0014] Furthermore, the movable rod has a central hole communicating with the cavity, and the stop bar has a connecting hole communicating with the movable groove.

[0015] Furthermore, the connecting frame is provided with an auxiliary component, which includes a protective gas duct fixedly installed on the connecting frame, a corrugated pipe fixedly installed on the protective gas duct, a pair of branch pipes fixedly installed on the corrugated pipe, and an air outlet fixedly installed at the end of each branch pipe away from the corrugated pipe. Two sets of temperature guiding plates are fixedly installed on the mounting housing, the temperature guiding plates are in contact with the coolant in the cavity, and the temperature guiding plates are located below the air outlets.

[0016] Furthermore, a polishing assembly is provided on one side of the connecting member. The polishing assembly includes a boss fixedly installed on the connecting member, a swing rod rotatably installed on the boss, a micro motor slidably installed on the swing rod, a polishing brush fixedly installed on the output shaft of the micro motor, one end of a spring fixedly installed on the micro motor, and the other end of the spring fixedly connected to the swing rod.

[0017] A smart welding method for pre-coated steel sheets, the method employing the aforementioned smart welding system for pre-coated steel sheets, includes the following steps:

[0018] S1: Place the body of the color-coated plate to be welded on the frame, start the adjustment component in the control box, the first and second motors drive the first and second adjustment belts to move the second adjustment frame and slider, so that the laser head is aligned with the weld seam, and the telescopic component adjusts the welding distance so that the abutment wheel adaptively fits the surface of the color-coated plate.

[0019] S2: The laser head starts welding, and the baffle of the partition component slides along the positioning rod. Through the cooperation of the inclined bottom end and the movable block, it adaptively adjusts with the shape of the color-coated plate to block the heat conduction of the laser to the coating on both sides.

[0020] S3: The adjustment component continuously drives the welding mechanism to move along the weld seam, maintaining a stable welding trajectory. After completion, the laser head is turned off, all adjustment components are reset, the welded color-coated plate body is removed, and one welding operation is completed.

[0021] The present invention has the following beneficial effects:

[0022] (1) The intelligent welding system and welding method for color-coated steel sheets: the slider drives the movable rod and the mounting block to move through the connecting frame; the laser head on the mounting block is used to realize the welding operation of the color-coated steel sheet; the telescopic component on the extension plate cooperates with the abutting wheel to change the height position of the laser head and achieve the effect of adjusting the welding distance; when the slider drives the movable rod and the mounting block to move, the abutting wheel moves on the surface of the color-coated steel sheet body; when the abutting wheel contacts the protruding part of the color-coated steel sheet body, the abutting wheel drives the mounting block to slide on the movable rod through the telescopic component, so that the laser head can adapt to the undulation of the color-coated steel sheet body to adjust the welding distance and ensure the stability during welding.

[0023] (2) In the intelligent welding system and welding method for color-coated steel sheets, after the first motor is started, it drives the first adjusting belt to rotate through the output shaft, which in turn drives the second adjusting frame to slide along the first adjusting frame, thereby realizing the position adjustment of the welding mechanism in one direction. After the second motor on the second adjusting frame is started, it drives the second adjusting belt to rotate through the output shaft, which drives the slider to slide along the second adjusting frame, thereby realizing the position adjustment of the welding mechanism in another direction, realizing the precise positioning of the welding mechanism, and improving the accuracy and flexibility of the welding position adjustment.

[0024] (3) When welding color-coated steel sheet bodies of different thicknesses, the welding distance used by the intelligent welding system and welding method will also change. In order to ensure the welding effect, when the double-headed screw is rotated, the two connecting parts will be driven to move closer or further away from each other due to the opposite thread grooves opened at both ends, which will drive the first rotating rod and the second rotating rod to rotate, change the height of the mounting part, change the distance between the abutment wheel and the extension plate, and thus change the distance between the laser head and the color-coated steel sheet body, which will also play the role of adjusting the welding torch.

[0025] (4) In the intelligent welding system and welding method for color-coated steel sheets, when the laser head is welding, the baffle is located on both sides of the laser head to form a physical barrier, which prevents the laser heat from spreading to the coating on both sides of the color-coated steel sheet. When the mounting block moves the laser head, the mounting shell can also move the baffle accordingly, changing the heat isolation position, effectively reducing the heat-affected zone, and protecting the coating from being damaged by high temperature.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0049] The following is based on Figure 1 - Figure 12 This invention describes the intelligent welding system and welding method for color-coated steel sheets provided in embodiments of the present invention.

[0050] On the one hand, the present invention provides an intelligent welding system for color-coated steel sheets.

[0051] Please see Figure 1 - Figure 4 The intelligent welding system for color-coated steel sheets includes a frame 10, on which a color-coated steel sheet body 11 to be welded is placed. A control box 12 is fixedly installed on the frame 10. An adjustment component 20 is provided on the frame 10 and a welding mechanism 30 is connected through the adjustment mechanism.

[0052] The welding mechanism 30 includes a slider 31, a connecting frame 32 fixedly mounted on the slider 31, a pair of movable rods 33 fixedly mounted on the connecting frame 32, mounting blocks 34 slidably mounted on each of the pair of movable rods 33, an extension plate 36 fixedly mounted on the mounting block 34, an abutment wheel 37 connected to the extension plate 36 via a telescopic component 40, and a laser head 35 fixedly mounted on the mounting block 34.

[0053] The frame 10 provides the installation foundation for the entire system. The color-coated steel sheet body 11 to be welded is placed on the frame 10. The control box 12 acts as the control core to coordinate the work of each component. The adjustment component 20 can drive the welding mechanism 30 to adjust its position on the frame 10 so that the welding mechanism 30 is aligned with the area to be welded. In the welding mechanism 30, the slider 31 drives the movable rod 33 and the mounting block 34 to move through the connecting frame 32. The laser head 35 on the mounting block 34 is used to realize the welding operation of the color-coated steel sheet. The telescopic component 40 on the extension plate 36 cooperates with the abutment wheel 37 to change the height position of the laser head 35 to achieve the effect of adjusting the welding distance. When the slider 31 drives the movable rod 33 and the mounting block 34 to move, the abutment wheel 37 moves on the surface of the color-coated steel sheet body 11. When the abutment wheel 37 contacts and passes through the protruding part of the color-coated steel sheet body 11, the abutment wheel 37 drives the mounting block 34 to slide on the movable rod 33 through the telescopic component 40, so that the laser head 35 can adapt to the undulation of the color-coated steel sheet body 11 to adjust the welding distance and ensure the stability during welding.

[0054] It should be noted that the weight of the laser head 35, mounting block 34, extension plate 36 and telescopic component 40, in conjunction with the abutment wheel 37, can further limit the position of the color-coated plate body 11 during welding, thereby further improving welding stability and welding effect.

[0055] Please see Figure 3 The adjustment assembly 20 includes a first adjustment frame 21 fixedly mounted on the frame 10, a second adjustment frame 24 slidably mounted on the first adjustment frame 21, a first motor 22 fixedly mounted on the first adjustment frame 21, a first adapter 27 fixedly mounted on the first adjustment frame 21, a first adjustment belt 23 for connecting the second adjustment frame 24 sleeved on the output shaft of the first motor 22 and the adapter, a slider 31 slidably mounted on the second adjustment frame 24, a second motor 25 fixedly mounted on the second adjustment frame 24, a second adapter 28 fixedly mounted on the second adjustment frame 24, and a second adjustment belt 26 for connecting the slider 31 sleeved on the output shaft of the second motor 25 and the second adapter 28.

[0056] After the first motor 22 starts, it drives the first adjusting belt 23 to rotate through the output shaft, which in turn drives the second adjusting frame 24 to slide along the first adjusting frame 21, thereby adjusting the position of the welding mechanism 30 in one direction. After the second motor 25 on the second adjusting frame 24 starts, it drives the second adjusting belt 26 to rotate through the output shaft, which drives the slider 31 to slide along the second adjusting frame 24, thereby adjusting the position of the welding mechanism 30 in another direction. This achieves precise positioning of the welding mechanism 30 and improves the accuracy and flexibility of the welding position.

[0057] Please see Figure 5The telescopic assembly 40 includes a pair of protrusions 41 fixedly mounted on the extension plate 36. A first rotating rod 42 is rotatably mounted on the protrusions 41. A connector 43 is provided at the end of the first rotating rod 42 away from the protrusions 41. A second rotating rod 44 is rotatably mounted on the connector 43. A mounting member 45 is provided at the end of the second rotating rod 44 away from the connector 43. The abutment wheel 37 is rotatably mounted on the mounting member 45. A double-ended screw 46 is threadedly connected to the pair of connectors 43. A pair of opposite threaded grooves are provided on the double-ended screw 46.

[0058] When welding color-coated steel sheet bodies 11 of different thicknesses, the welding distance will also change accordingly. In order to ensure the welding effect, when the double-ended screw 46 is rotated, because its two ends have opposite threaded grooves, it will drive the two connecting parts 43 to move closer or further away from each other, thereby driving the first rotating rod 42 and the second rotating rod 44 to rotate, changing the height of the mounting part 45, changing the distance between the abutment wheel 37 and the extension plate 36, and thus the distance between the laser head 35 and the color-coated steel sheet body 11 will also change accordingly, which will have the effect of adjusting the welding torch.

[0059] Please see Figure 7 - Figure 10 The mounting block 34 is provided with a partition assembly 50. The baffle 53 included in the partition assembly 50 can adapt to the shape of the color-coated plate body 11 and reduce the thermal impact of the laser head 35 on the paint on both sides of the color-coated plate body 11 when welding it. The partition assembly 50 includes a pair of mounting shells 51 fixedly mounted on the mounting block 34. Two sets of symmetrically arranged positioning rods 52 are fixedly mounted inside the mounting shells 51. The baffle 53 is slidably mounted on the positioning rods 52.

[0060] When the laser head 35 is welding, the baffle 53 is located on both sides of the laser head 35, forming a physical barrier to prevent the laser heat from spreading to the coating on both sides of the color-coated plate. When the mounting block 34 moves the laser head 35, the mounting housing 51 can also move the baffle 53 accordingly, changing the position of the heat isolation, effectively reducing the heat-affected zone and protecting the coating from high temperature damage.

[0061] Please see Figure 9 The bottom end of the baffle 53 is inclined, and the inclined surfaces of the bottom ends of the symmetrical baffles 53 are opposite. The baffle 53 is provided with a movable groove 54, and a movable block 55 is slidably installed in the movable groove 54.

[0062] The movable block 55 can slide in the movable groove 54 according to the undulation of the color-coated sheet surface. When the baffle 53 is located on the side of the undulating part of the color-coated sheet body 11, the movable block 55 will retract into the movable groove 54. At this time, the inclined surface of the baffle 53 will fit against the undulating side, reducing the gap between the baffle 53 and the color-coated sheet. The two sets of baffles 53 with opposite bottom inclined surfaces can fit well into both sides of the undulating part of the color-coated sheet body 11, improving the adaptability of the baffle 53 to the color-coated sheet surface, enhancing the thermal insulation effect, and reducing heat leakage.

[0063] Please see Figure 6 - Figure 8 The mounting housing 51 has a cavity 56 for the flow of coolant. A pair of connecting parts 57 communicating with the cavity 56 are fixedly installed on the mounting housing 51. One of the connecting parts 57 is fixedly installed with an inlet pipe 58, and the other connecting part 57 is fixedly installed with an outlet pipe 59.

[0064] The inlet pipe 58 inputs coolant into the cavity 56 through the connector 57. When the coolant flows in the cavity 56, it absorbs the heat transferred by the mounting housing 51 and the baffle 53, and then discharges it from the outlet pipe 59 through another connector 57, forming a circulating cooling system. This reduces the temperature of the baffle 53 and the mounting housing 51, preventing them from losing their heat insulation ability due to high temperature and extending the life of the components.

[0065] Please see Figure 10 The movable rod 33 has a central hole 510 communicating with the cavity 56, and the baffle 53 has a communicating hole 511 communicating with the movable groove 54;

[0066] The central hole 510 on the movable rod 33 connects the cavity 56 of the mounting housing 51 with the interior of the movable rod 33, allowing coolant to flow into the movable rod 33. The connecting hole 511 in the baffle 53 connects the movable groove 54 with the central hole 510, allowing coolant (water) to enter the movable groove 54 and directly cool the interior of the movable block 55 and the baffle 53. At the same time, a small amount of coolant will flow out along the gap between the movable block 55 and the movable groove 54 and come into contact with the color-coated plate body 11, improving the cooling effect of the welding area and further reducing the heat impact. Meanwhile, the coolant can reduce the friction caused by the sliding of the baffle 53, improve the movement effect of the baffle 53, improve the overall heat dissipation efficiency, and enhance the thermal insulation effect.

[0067] Please see Figure 6The connecting frame 32 is provided with an auxiliary component 60. The auxiliary component 60 includes a protective gas duct 61 fixedly installed on the connecting frame 32. A corrugated pipe 62 is fixedly installed on the protective gas duct 61. A pair of branch pipes 63 are fixedly installed on the corrugated pipe 62. An outlet 64 is fixedly installed at the end of each branch pipe 63 away from the corrugated pipe 62. Two sets of temperature guiding plates 65 are fixedly installed on the mounting housing 51. The temperature guiding plates 65 are in contact with the coolant in the cavity 56. The temperature guiding plates 65 are located below the outlet 64.

[0068] The protective gas duct 61 delivers protective gas (such as argon), which is buffered by the bellows 62 and then sprayed out from the gas outlet 64 through the branch pipe 63, covering the welding area and isolating it from air to prevent weld oxidation. At the same time, the heat-conducting plate 65 on the housing 51 comes into contact with the coolant in the cavity 56, absorbs heat and lowers its temperature, pre-cooling the protective gas sprayed out from the gas outlet 64. The cooled protective gas further reduces the temperature of the welding area, reduces weld oxidation, and improves welding quality. At the same time, the cooled protective gas enhances the cooling effect of the welding area and reduces the heat-affected zone.

[0069] Please see Figure 12 A polishing assembly 70 is provided on one side of the connecting member 57. The polishing assembly 70 includes a boss 71 fixedly installed on the connecting member 57. A swing rod 72 is rotatably installed on the boss 71. A micro motor 73 is slidably installed on the swing rod 72. A polishing brush 74 is fixedly installed on the output shaft of the micro motor 73. One end of a spring 75 is fixedly installed on the micro motor 73. The other end of the spring 75 is fixedly connected to the swing rod 72.

[0070] The boss 71 is fixed on the connecting piece 57, providing a pivot point for the swing rod 72. The swing rod 72 can adaptively adjust the grinding angle according to the undulation of the color-coated plate body. The micro motor 73 slides on the swing rod 72, and its output shaft drives the grinding brush 74 to rotate. The elastic force of the micro motor 73 and the spring 75 work together to achieve the effect of adaptively adjusting the undulation of the weld surface, efficiently grinding and repairing the weld, improving the grinding effect of the weld, reducing subsequent manual grinding steps, and improving work efficiency.

[0071] On the other hand, the present invention also provides an intelligent welding method for color-coated steel sheets, which uses the above-mentioned intelligent welding system for color-coated steel sheets and includes the following steps:

[0072] S1: Place the body 11 of the color-coated plate to be welded on the frame 10, start the adjustment component 20 in the control box 12, drive the first and second motors to drive the first and second adjustment belts to move the second adjustment frame 24 and slider 31, so that the laser head 35 is aligned with the weld seam, and the telescopic component 40 adjusts the welding distance so that the abutment wheel 37 adaptively fits the surface of the color-coated plate.

[0073] S2: The laser head 35 starts welding, and the baffle 53 of the partition component 50 slides along the positioning rod 52. Through the cooperation of the inclined bottom end and the movable block 55, it adaptively adjusts with the shape of the color-coated plate to block the heat conduction of the laser to the coating on both sides.

[0074] S3: The adjustment component 20 continuously drives the welding mechanism 30 to move along the weld seam, maintaining a stable welding trajectory. After completion, the laser head 35 is turned off, all adjustment components are reset, the welded color-coated plate body 11 is removed, and one welding operation is completed.

[0075] During use (working), the color-coated steel sheet body 11 to be welded is placed on the frame 10, the control box 12 starts the system, in the adjustment component 20, the first motor 22 drives the second adjustment frame 24 to slide along the first adjustment frame 21 through the first adjustment belt 23, the second motor 25 drives the slider 31 to slide along the second adjustment frame 24 through the second adjustment belt 26, and moves the welding mechanism 30 above the weld seam. In the telescopic component 40, the double-headed screw 46 is rotated to drive the connecting piece 43 to move, so that the first rotating rod 42, the second rotating rod 44 adjust the position of the mounting piece 45 and the abutment wheel 37, and adjust the welding distance between the laser head 35 and the color-coated steel sheet body 11.

[0076] The laser head 35 is activated to weld the weld seam. In the partition component 50, the baffle 53 slides along the positioning rod 52, and the bottom inclined surface cooperates with the movable block 55 to fit the color-coated plate and block the heat diffusion. At the same time, the coolant in the cavity 56 enters through the inlet pipe 58 and exits through the outlet pipe 59, and cools the baffle 53 and the movable block 55 through the central hole 510 and the connecting hole 511. In the auxiliary component 60, the protective gas is sprayed out from the gas outlet 64 to isolate the air, and the heat conduction plate 65 cools the protective gas to assist in cooling.

[0077] The adjusting component 20 continuously drives the welding mechanism 30 to move along the weld seam to ensure welding continuity. During the welding process, the micro motor 73 of the grinding component 70 drives the grinding brush 74 to grind the weld seam under the action of the spring 75. Finally, all adjusting components are reset and the welded color-coated plate body 11 is removed.
