Description

Technical Field

[0001] The present invention relates to the technical field of door and window processing, and more particularly to a positioning and control system for 6- and 8-branch laser welding. Background Art

[0002] In the door and window assembly process, laser welding technology plays a vital role. It uses a high-energy laser beam as a heat source to precisely heat the workpiece locally, melting and fusing the material to form a stable molten pool, thereby achieving high-quality welding.

[0003] In the door and window industry, 6 and 8 profiles refer to the number of profiles used in the door and window manufacturing process. When processing doors and windows, the profiles are first placed and clamped according to the required door and window shape, and then the welding points of the profiles are laser welded using a welding robot. When processing multiple profiles, especially the assembly and welding of horizontal and vertical profiles, due to their structural characteristics, four-sided welding is required to ensure stability. The welding robot needs to weld each welding surface in sequence. However, in the process of transitioning from front welding to side welding, the laser welding head will generate a certain contact pressure when contacting the side welding point. Although the profile has been effectively fixed by the clamping device to avoid large offsets, this contact pressure may still cause slight displacement on the side. Although this displacement is small, it is enough to affect the precise loading of subsequent door and window glass.

[0004] To this end, the present application proposes a positioning and control system for 6 and 8-branch laser welding to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present application provides a positioning and control system for 6 and 8-branch laser welding, which solves the problem that when processing multiple horizontal and vertical profiles for door and window processing and assembly welding, the side weld points contact the laser welding head to generate contact pressure during the four-sided welding process of the welding robot, causing slight displacement of the profile and affecting the subsequent loading accuracy of the door and window glass. When used, it effectively avoids the deviation of the branches, optimizes the alignment of the materials after welding, and ensures the flatness and smoothness of the welding parts, thereby preventing the problem of door and window installation blockage caused by slight deviation, and realizing the refinement and efficiency of the welding process.

[0041] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0042] Example 1

[0043] See also Figures 1-14, a positioning device for laser welding of 6 and 8 supports, including a clamping table 1, the middle part of the clamping table 1 is rotatably connected to the supporting table 2, the top of the supporting table 2 is slid with four mounting plates 3, the mounting plate 3 includes a bidirectional screw rod 31 and a unidirectional screw rod 32 and a transmission device 33, the bidirectional screw rod 31 and the unidirectional screw rod 32 are both rotatably mounted on the top of the mounting plate 3, the bidirectional screw rod 31 and the unidirectional screw rod 32 are respectively connected and driven by the corresponding transmission devices 33 fixed to the rear side of the mounting plate 3, the front and rear sides of the bidirectional screw rod 31 are threadedly connected to the docking table 4, the unidirectional screw rod 32 is threadedly connected to the horizontal material table 5, the horizontal material table 5 is installed with a resistance component 6, and a fixed suction component 7 is installed in the resistance component 6, the clamping table 1 is connected to the control console 8 through a wire, and a mechanical arm 9 is provided at the rear of the clamping table 1, A CNC welding head 10 is installed at the end of the mechanical arm 9; the interference component 6 includes an assembly box 61 fixedly installed on the top of the horizontal material table 5, and two limit boxes 62 are installed on both sides of the top of the assembly box 61. A support column 63 is fixed in the middle of the limit box 62, and a permanent magnet 64 is slid on the outside of the support column 63. The outward side of the permanent magnet 64 is connected to the outer inner wall of the assembly box 61 through a spring 65, and the outer inner wall of the assembly box 61 is also installed with an electromagnet 66, and the inward side of the permanent magnet 64 is fixedly installed with a interference plate 67; the fixed suction component 7 includes two vacuum suction cups 71. After the friction component 6 is used to correct the horizontal support welding friction offset, the vacuum suction cup 71 is used to draw air to form a vacuum and adsorb and position the bottom of the support. The bottom end of the vacuum suction cup 71 is fixedly connected to an exhaust pipe 72.

[0044] In this example, see Figures 1-14 As shown, during the processing of 8-branch door and window materials, the console 8 is used to control the rotation of the loading platform 2 so that the loading platform 2 and the four mounting plates 3 thereon are in a forward tilted state of 30-60 degrees. Then, the door and window materials are sequentially placed in the placement space formed by the docking platform 4 and the horizontal material platform 5, and are rotated and locked by the limit rotating frame 16 on the docking platform 4 and the horizontal material platform 5. Then, the laser welding process is started, and the robot arm 9 and the CNC welding head 10 are used to perform front welding processing on the diagonal parts and the horizontal and vertical material connections of the door and window materials. After the front welding is completed, the console 8 is used to control the rotation of the loading platform 2 to rotate 180 degrees. The robot arm 9 and the CNC welding head 10 then perform reverse welding processing on the diagonal parts and the horizontal and vertical material connections of the door and window materials through the welding grooves 14 on the docking platform 4 and the horizontal material platform 5, that is, the welding of 8-branch door and window materials is completed. At the same time, the welding process of 6-branch materials is the same as the processing process of 8-branch materials ( Figure 13 shown).

[0045] Regarding the above welding process, when executing the horizontal and vertical support welding process, when the welding point transitions from front (top) welding to side welding, the laser welding head 10 will contact the side weld, and a certain contact pressure will be generated during welding, resulting in the displacement of the corresponding horizontal support position ( Figure 14 As shown), therefore, by utilizing the resistance component 6, when the laser welding head 10 transitions to the side welding point, the sensor 2 13 on the laser welding head 10 senses and receives signals from the sensor 1 12 on the same side, and the signal is transmitted to the controller 11 on the other side by the sensor 12. The controller 11 on the other side generates magnetism by utilizing the electromagnet 66 to produce a magnetic repulsion effect on the permanent magnet 64. The permanent magnet 64 then slides inward on the support column 63 and drives the resistance plate 67 connected to itself to pass through the plate opening 69 on the supporting plate 68, so that the resistance plate 67 resists and pushes the other side of the support material close to the outer surface of the weld seam, thereby forming an interaction force on both sides, ensuring the stability of the support material, effectively avoiding the deviation of the support material, optimizing the material alignment after welding, and ensuring the flatness and smoothness of the welding part, thereby preventing the problem of door and window installation blockage caused by slight deviation, and realizing the refinement and efficiency of the welding process.

[0046] Further, see Figures 8-10 A supporting plate 68 is fixedly installed on the inner side of the limit box 62, and a plate opening 69 is opened in the middle of the supporting plate 68. The plate opening 69 is consistent with the size of the contact plate 67. By setting the supporting plate 68 and the plate opening 69, the supporting plate 68 is first used as an object for supporting the two sides of the support material, and the supporting plate 68 with a certain thickness can be adjusted and replaced, which is convenient for supporting the support material within a certain width range. In addition, a plate opening 69 is opened on it, which does not affect the support of the support material, and can also facilitate the extension of the contact plate 67 to perform the offset correction operation of the support material.

[0047] Further, see Figure 8 and Figure 9 The bottom of the limit box 62 is provided with a sliding groove 610, and a slider 611 is slidably connected in the sliding groove 610. The top of the slider 611 is fixedly connected to the bottom end of the permanent magnet 64. The sliding groove 610 is respectively opened at the front and back parts of the top of the assembly box 61. By setting the sliding groove 610 and the slider 611, the sliding groove 610 is used to provide a stable moving trajectory for the slider 611. On the one hand, the movement stability of the permanent magnet 64 connected at the top is guaranteed, and on the other hand, the movement stability of the extrusion column 74 connected at the bottom is also guaranteed, which is a moving space that provides driving force for the operation of the fixed suction component 7.

[0048] Further, see Figure 6 、 Figure 10 and Figure 11, a controller 11 is fixedly installed on the outer side of the top of the two limit boxes 62, and the controller 11 is electrically connected to the electromagnet 66. A sensor 12 is fixedly connected to the inner side of the top of the limit box 62. The controller 11 on the front limit box 62 is electrically connected to the sensor 12 on the rear limit box 62, and the controller 11 on the rear limit box 62 is electrically connected to the sensor 12 on the front limit box 62. The controller 11 is used to control the start and stop of the magnetization of the electromagnet 66, and the controller 11 also receives the control signal transmitted by the sensor 12. At the same time, the controllers 11 and the sensor 12 on the two limit boxes 62 are in an interlaced control state, which facilitates the conflict component 6 to generate a conflicting force in opposite directions.

[0049] Further, see Figure 7 A sensor 2 13 is installed on the side of the CNC welding head 10. The sensor 2 13 is inductively coupled with the two sensor 1s 12 respectively. The sensor 2 13 on the CNC welding head 10 transmits a control signal to the sensor 1 12. The sensor 2 13 can only control one sensor 1 12 at a time.

[0050] In summary, this embodiment forms a resistance force on the other side of the CNC welding head 10 by setting a resistance component 6, thereby generating a reverse force with the contact pressure of the CNC welding head 10, ensuring the stability of the material support, effectively avoiding the deviation of the material support, optimizing the material alignment after welding, and ensuring the flatness and smoothness of the welding part, thereby preventing the problem of door and window installation blockage caused by slight deviation, and realizing the refinement and efficiency of the welding process.

[0051] Example 2

[0052] See also Figure 8 、 Figure 9 and Figure 12 The fixed suction component 7 also includes an L-shaped through pipe 73 fixedly connected to the front and rear sides of the middle part of the top wall of the assembly box 61. One end of the L-shaped through pipe 73 is slidably connected to an extrusion column 74, and the other end of the L-shaped through pipe 73 is slidably connected to a connecting column 1 75. The bottom end of the connecting column 1 75 is fixedly connected to one side of the top of the counterweight plate 76, and the other side of the top of the counterweight plate 76 is fixedly connected to a connecting column 2 77. The connecting column 2 77 is slidably connected to the inside of the exhaust pipe 72, and a drain valve 78 is installed on the side of the exhaust pipe 72.

[0053] In this example, see Figure 8 、 Figure 9 and Figure 12As shown, the movement of the extrusion column 74 in the L-shaped tube 73 is used as a driving force, and then the air pressure squeezes the connecting column 1 75 at the other end of the L-shaped tube 73 to start moving downward, and the connecting column 1 75 then drives the connecting column 2 77 to move downward synchronously through the connected counterweight plate 76. As the connecting column 2 77 moves downward inside the exhaust pipe 72 to exhaust air, the air in the exhaust pipe 72 and the exhaust suction cup 71 close to the bottom of the support material is sucked in, causing it to start to absorb air and firmly adsorb the support material that has been corrected in position, thereby achieving temporary fixation of the support material, providing a stable foundation for the subsequent reversal and welding operations of the side welding point on the other side, and ensuring the smooth progress of the welding process.

[0054] Further, see Figure 12 The outward end of the extrusion column 74 is fixedly connected to the lower part of the slider 611, and the inward ends of the extrusion column 74, the connecting column 1 75 and the connecting column 2 77 are fixedly installed with a sealing ring 79. The sealing ring 79 is used to enhance the sealing performance of the extrusion column 74, the connecting column 1 75 and the connecting column 2 77 during the sliding process, ensuring that the airtightness is always maintained during the movement, thereby ensuring that the connecting column 1 75 and the connecting column 2 77 can smoothly and stably execute the moving state of being squeezed downward by the extrusion column 74, thereby improving the overall operating efficiency and reliability of the fixed suction component 7.

[0055] For further information, see Figure 6 A welding groove 14 is provided in the middle of the horizontal material table 5, and small motors 15 are installed on the left and right sides of the front top of the horizontal material table 5. A limiting turntable 16 is fixedly installed on the top output end of the small motor 15. The limiting turntable 16 is driven to rotate by the small motor 15, which can achieve a stable fixation of the top of the support material. When welding the back side of the support material, it can ensure that the support material can remain in a stable and fixed state after being flipped, thereby ensuring the smooth progress of the welding operation.

[0056] Further, see Figure 3 The docking platform 4 is divided into a diagonal platform 41 and a splicing platform 42. A right-angle block 43 is installed at the top corner of the diagonal platform 41, and a horizontal block 44 and a vertical block 45 are installed at the front and rear of the splicing platform 42 respectively. A small motor 15 and a limit rotating frame 16 fixedly connected to the output end of the small motor 15 are installed on the top of the diagonal platform 41 and the splicing platform 42, and a welding groove 14 is also provided in the middle of the diagonal platform 41 and the splicing platform 42. By utilizing the diagonal platform 41 and the splicing platform 42 in the docking platform 4, the stable fixation of the diagonal assembling materials can be effectively achieved, and at the same time, the firmness of the materials in the horizontal and vertical directions can be ensured, thereby enhancing the stability of the entire door and window frame and laying a solid foundation for subsequent assembly and molding work.

[0057] In summary, this embodiment uses the fixed suction component 7 to utilize the extrusion column 74 to move and drive the air pressure to squeeze the connecting column 1 75 at the other end of the L-shaped through tube 73 and the connecting column 2 77 connected to it through the counterweight plate 76 to evacuate the exhaust pipe 72, so that the exhaust suction cup 71 firmly absorbs the corrected support material to ensure the stable progress of subsequent welding.
