Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy door and window welding technology, specifically relating to a welding device for intelligent aluminum alloy door and window processing. Background Technology

[0002] Intelligent aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. They are also called aluminum doors and windows for short. When aluminum alloy doors and windows are manufactured, they need to be welded. However, during welding, the components of the aluminum alloy doors and windows need to be aligned neatly. Otherwise, the welding will be uneven, and the aluminum alloy doors and windows will not be on the same plane, which will affect the subsequent use.

[0003] Chinese invention patent CN113006379A discloses an automatic aluminum alloy door and window welding device and method, including a fixing device and a positioning device disposed on top of the fixing device. The fixing device includes a fixing platform, and the positioning device includes a driving mechanism. The driving mechanism includes four mounting members, and a synchronization structure is provided between the four mounting members to drive the four mounting members to move synchronously. An adjustment structure is provided around the fixing platform. In the aforementioned application, because the mounting members change angle with the inclined plane during the process of driving the four aluminum alloy workpieces upward and aligning, and because the mounting members only abut against one side of the aluminum alloy workpieces, the aluminum alloy workpieces are prone to displacement when the mounting members move to the top, thus making the subsequent welding process difficult. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent welding device for processing aluminum alloy doors and windows, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a welding device for processing intelligent aluminum alloy doors and windows, including a base plate, welding robotic arms movably connected to the top of the four sides of the base plate, a support column fixedly connected to the top of the center of the base plate, a driving device fixedly connected to the top of the support column, a drive screw movably connected inside the driving device, a motor fixedly connected to the top of the drive screw, and multiple inclined sliding grooves opened inside the driving device, with a support frame movably connected inside the inclined sliding grooves. The top of the drive device is fixedly connected to multiple fixed plates, and the bottom of each fixed plate is fixedly connected to an inclined guide block. The support frame has a sliding groove inside the side near the drive device, and a sliding rod is movably connected inside the sliding groove. The bottom of the support frame is fixedly connected to a C-shaped fixed plate, and a spring is fixedly connected between the bottom of the sliding rod and the C-shaped fixed plate. The top of the sliding rod has an inclined sliding surface. The support frame has a sliding groove inside, and a slider is movably connected inside the sliding groove. A connecting rod is hinged between the end of the slider near the drive screw and the top of the sliding rod. A C-shaped clamp is fixedly connected to the top of the slider. Multiple telescopic rods are fixedly connected to both sides of the C-shaped clamp away from the drive screw. A positioning docking plate is fixedly connected to the ends of every two telescopic rods away from the drive screw. A spring is fixedly connected between the positioning docking plate and the C-shaped clamp. A positioning and docking plate is installed. When the equipment is started, it works with the drive screw, support frame, inclined guide block, slide rod, connecting rod, slider, and C-shaped clamp to move the support frame diagonally upward to the top. This causes the C-shaped clamp to move outward, so that the positioning and docking plate fits against the rear surface of the aluminum alloy workpiece, and the support frame fits against the bottom and front surfaces of the aluminum alloy workpiece. This forms a fixed position for the aluminum alloy workpiece, and the positioning and docking plate corrects any deviation that occurs during the upward movement of the aluminum alloy workpiece. This makes the aluminum alloy workpiece more stable during subsequent welding, reduces manual adjustment, and makes the equipment easier to use.

[0006] According to the above technical solution, the left and right ends of the C-shaped clamp correspond to the left and right ends of the support frame, and an aluminum alloy workpiece is placed on the top of the support frame.

[0007] According to the above technical solution, the height of the positioning docking plate is less than the height of the aluminum alloy workpiece, and the distance between the positioning docking plate and the support frame is consistent with the thickness of the aluminum alloy workpiece.

[0008] According to the above technical solution, the bottom surface of the C-shaped fixing plate is slightly higher than the top surface of the support frame, and an auxiliary unloading assembly is movably connected to the top of the base plate.

[0009] According to the above technical solution, the auxiliary unloading assembly includes a second fixed plate, a third fixed plate, a torsion spring, a first rotating shaft, a trigger rod, an inclined surface, a support rod, a C-shaped lifting plate, a second telescopic rod, a third spring, and a contact plate. The left and right outer sides of the front and rear support frames are fixedly connected to the second fixed plate. Multiple third fixed plates are fixedly connected to the top of the base plate. A first rotating shaft is movably connected between every two third fixed plates. A torsion spring is fixedly connected at the connection between the first rotating shaft and the third fixed plate. A trigger rod is fixedly connected to the outer side of the first rotating shaft. An inclined surface is formed on one end of the trigger rod near the second fixed plate. A support rod is fixedly connected to the other end of the trigger rod. A C-shaped lifting plate is fixedly connected to the top of the support rod. Multiple second telescopic rods are fixedly connected to the top of the inner side of the C-shaped lifting plate. A contact plate is fixedly connected to the top of the second telescopic rod. A third spring is fixedly connected between the contact plate and the top of the inner side of the C-shaped lifting plate. An auxiliary unloading component is installed. When the equipment is running, it works with the support frame, fixed plate two, torsion spring, rotating shaft one, trigger rod, inclined plane, support rod, and C-shaped lifting plate to make the C-shaped lifting plate rotate upward with the trigger rod. This causes the top of the contact plate to contact the bottom of the welded aluminum alloy door and window, automatically lifting the aluminum alloy door and window upward, thus facilitating the subsequent unloading process and improving the equipment's operating efficiency.

[0010] According to the above technical solution, the length of the contact plate is less than the length of the C-shaped lifting plate, and the movement trajectory of the C-shaped lifting plate contacts the outer side of the aluminum alloy door and window after welding.

[0011] According to the above technical solution, the outer movement trajectory of the support frame does not contact the outer movement trajectory of the C-shaped lifting plate, and a correction component is movably connected to the top of the base plate.

[0012] According to the above technical solution, the correction assembly includes a second rotating shaft, a first bevel gear, a second bevel gear, a lead screw, a fourth fixed plate, a second sliding groove, a slider, an L-shaped correction plate, and a welding guide plate. The bottom of the drive lead screw is fixedly connected to the second rotating shaft. The outer side of the second rotating shaft is movably connected to the inside of the support column. The outer bottom of the second rotating shaft is fixedly connected to the first bevel gear. Multiple lead screws are movably connected inside the support column. The end of each lead screw near the first bevel gear is fixedly connected to the second bevel gear, which meshes with the first bevel gear. The other end of each lead screw is movably connected to the fourth fixed plate. The bottom of the fourth fixed plate is fixedly connected to the top of the base plate. The bottom rear side of the fourth fixed plate is fixedly connected to the second sliding groove. The inside of the second sliding groove is movably connected to the vertical slider. The top of the vertical slider is fixedly connected to the L-shaped correction plate. The inner side of the L-shaped correction plate is fixedly connected to the welding guide plate. The corrective assembly is set up so that when the equipment is running, it works with the second rotating shaft, the first bevel gear, the second bevel gear, the lead screw, the second slide groove, and the vertical slider to move the vertical slider along the direction of the second slide groove towards the side closer to the support column. This causes the inner surface of the L-shaped corrective plate to contact the two sides of the aluminum alloy workpiece, thereby correcting the slight horizontal deviation of the aluminum alloy workpiece by the L-shaped corrective plate, making the subsequent welding process smoother.

[0013] According to the above technical solution, the bottom surface of the welding guide plate does not contact the surface of the aluminum alloy workpiece, and a weld guide line is provided at the center of the welding guide plate.

[0014] According to the above technical solution, the thread length of the lead screw is less than the length of the second slide groove.

[0015] The advantages of this application are: (1) When the equipment is started, the present application, in conjunction with the drive screw, support bracket, inclined guide block, slide rod, connecting rod, slider, and C-shaped clamp, causes the support bracket to move obliquely upward to the top, and the C-shaped clamp moves outward, so that the positioning docking plate is attached to the rear surface of the aluminum alloy workpiece, and the support bracket is attached to the bottom and front surface of the aluminum alloy workpiece, thereby forming a positioning and fixing of the aluminum alloy workpiece. The offset generated by the aluminum alloy workpiece during the rising process is corrected by the positioning docking plate, so that the aluminum alloy workpiece is more stable in subsequent welding, reducing human control and making the equipment more convenient to use.

[0016] (2) When the equipment is running, the present application, together with the support frame, the second fixed plate, the torsion spring, the first rotating shaft, the trigger rod, the inclined surface, the support rod, and the C-shaped lifting plate, makes the C-shaped lifting plate rotate upward with the trigger rod, so that the top of the contact plate contacts the bottom of the welded aluminum alloy door and window, and the aluminum alloy door and window is automatically lifted upward, thereby facilitating the subsequent unloading process and improving the operating efficiency of the equipment.

[0017] (3) When the equipment is running, the application uses the rotating shaft 2, bevel gear 1, bevel gear 2, lead screw, slide groove 2, and vertical slider to move the vertical slider along the slide groove 2 towards the side closer to the support column, so that the inner surface of the L-shaped straightening plate contacts the two sides of the aluminum alloy workpiece, thereby correcting the slight horizontal displacement of the aluminum alloy workpiece by the L-shaped straightening plate, making the subsequent welding process smoother.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-5 As shown, a welding device for processing intelligent aluminum alloy doors and windows includes a base plate 100. Welding robotic arms 200 are movably connected to the top of the four sides of the base plate 100. A support column 300 is fixedly connected to the top of the center of the base plate 100. A driving device 400 is fixedly connected to the top of the support column 300. A drive screw 500 is movably connected inside the driving device 400. A motor is fixedly connected to the top of the drive screw 500. Multiple inclined slides 600 are opened inside the driving device 400. A support frame 700 is movably connected inside the inclined slides 600. The support frame 700 moves slowly. Due to the gravity of the aluminum alloy workpiece 800, the bottom surface of the aluminum alloy workpiece 800 is always in contact with the top surface of the support frame 700. Multiple fixed plates 901 are fixedly connected to the top of the drive device 400 around its perimeter. Each fixed plate 901 has a fixedly connected inclined guide block 902 at its bottom. The inclined guide block 902 is configured so that when the support frame 700 moves the sliding rod 903 obliquely upwards, the inclined guide block 902 contacts the top of the sliding rod 903 before the support frame 700 is completely horizontal. This allows the positioning docking plate 912 to initially contact the rear surface of the aluminum alloy workpiece 800 during the initial sliding of the support frame 700. When the support frame 700 is completely horizontal, the positioning docking plate 912 is tightly attached to the rear surface of the workpiece. On the rear surface of the aluminum alloy workpiece 800, spring 2 911 and telescopic rod 1 910 are present. A sliding groove is formed inside the support frame 700 on the side near the driving device 400. A sliding rod 903 is movably connected inside the sliding groove. A C-shaped fixing plate 904 is fixedly connected to the bottom of the support frame 700. Spring 1 905 is fixedly connected between the bottom of the sliding rod 903 and the C-shaped fixing plate 904. A sloping sliding surface is formed at the top of the sliding rod 903. A sliding groove 1 908 is formed inside the support frame 700. A wear-resistant plate is fixedly connected to the inner surface of the sliding groove 1 908. A slider 907 is movably connected inside slot 908. A connecting rod 906 is hinged between the end of slider 907 near the drive screw 500 and the top of slide rod 903. A C-shaped clamping plate 909 is fixedly connected to the top of slider 907. The C-shaped clamping plate 909 is configured to allow the positioning mating plate 912 to fit against the inner surface of the aluminum alloy workpiece 800, thus positioning and fixing the aluminum alloy workpiece 800. This corrects any misalignment of the aluminum alloy workpiece 800 during its ascent, making the aluminum alloy workpiece 800 more stable during subsequent welding. To reduce manual adjustments and make the equipment more convenient to use, multiple telescopic rods 910 are fixedly connected to both sides of the C-shaped clamp 909 away from the drive screw 500. A positioning docking plate 912 is fixedly connected to the end of every two telescopic rods 910 away from the drive screw 500. When the support frame 700 moves obliquely upward to the top, the C-shaped clamp 909 moves outward, so that the positioning docking plate 912 fits against the rear surface of the aluminum alloy workpiece 800. A spring 911 is fixedly connected between the positioning docking plate 912 and the C-shaped clamp 909.

[0022] The left and right ends of the C-shaped clamp 909 correspond to the left and right ends of the support frame 700, and the aluminum alloy workpiece 800 is placed on top of the support frame 700. The height of the positioning mating plate 912 is less than the height of the aluminum alloy workpiece 800, and the distance between the positioning mating plate 912 and the support frame 700 is the same as the thickness of the aluminum alloy workpiece 800. The bottom surface of the C-shaped fixing plate 904 is slightly higher than the top surface of the support frame 700, and the top of the base plate 100 is movably connected to the auxiliary unloading assembly 1000.

[0023] In practical use, when the above-mentioned equipment is started, the motor is activated, causing the drive screw 500 to rotate. The drive screw 500 then moves the support frame 700 along the inclined slide groove 600, causing the support frame 700 to move the aluminum alloy workpiece 800 obliquely upwards. When the support frame 700 reaches its highest point, it rotates from an inclined state to a horizontal state. At this time, the top of the slide rod 903 contacts the bottom of the inclined guide block 902, causing the slide rod 903 to move downwards along the sliding groove. This compresses the spring 905 downwards, causing the slide rod 903 to move the connecting rod 906 obliquely downwards, thus moving the connecting rod 906... The movable slider 907 moves outward along the slide groove 908, causing the slider 907 to drive the C-shaped clamp 909 to move outward, which in turn drives the positioning docking plate 912 to move outward. This causes the positioning docking plate 912 to fit against the rear surface of the aluminum alloy workpiece 800, and the support bracket 700 to fit against the bottom and front surfaces of the aluminum alloy workpiece 800. This forms a positioning and fixing effect on the aluminum alloy workpiece 800, correcting any deviation that occurs during the upward movement of the aluminum alloy workpiece 800. This makes the aluminum alloy workpiece 800 more stable during subsequent welding, reduces manual adjustment, and makes the equipment more convenient to use.

[0024] Example 2, as Figures 2-7As shown, based on Embodiment 1, the auxiliary unloading assembly 1000 includes a second fixed plate 1001, a third fixed plate 1002, a torsion spring 1003, a first rotating shaft 1004, a trigger rod 1005, an inclined plane 1006, a support rod 1007, a C-shaped lifting plate 1008, a second telescopic rod 1009, a third spring 1010, and a contact plate 1011. The second fixed plate 1001 is fixedly connected to the left and right outer sides of the front and rear side support brackets 700. An elastic buffer pad is fixedly connected to the outer side of the second fixed plate 1001. The base plate 1 The top of the base plate 100 is fixedly connected to multiple fixing plates 1002. A rotating shaft 1004 is movably connected between every two fixing plates 1002. A torsion spring 1003 is fixedly connected to the connection between the rotating shaft 1004 and the fixing plate 1002. A return spring is fixedly connected between the bottom of the front end of the trigger rod 1005 and the base plate 100. The trigger rod 1005 is fixedly connected to the outer side of the rotating shaft 1004. A slope 1006 is formed on the surface of the trigger rod 1005 near the fixing plate 1001. The top horizontal height of 006 is lower than the bottom horizontal height of the support frame 700, so that the positioning docking plate 912 first loosens the welded aluminum alloy door and window, and then the C-shaped lifting plate 1008 lifts the aluminum alloy door and window. The other end of the trigger rod 1005 is fixedly connected to the support rod 1007. The top of the support rod 1007 is fixedly connected to the C-shaped lifting plate 1008. The C-shaped lifting plate 1008 is set so that it rotates upward with the trigger rod 1005. The inner top of the C-shaped lifting plate 1008 The unit is fixedly connected with multiple telescopic rods 1009. A contact plate 1011 is fixedly connected to the top of the telescopic rods 1009. An anti-slip pad is fixedly connected to the top surface of the contact plate 1011. The contact plate 1011 is set so that the top of the contact plate 1011 contacts the bottom of the welded aluminum alloy door and window, so that the aluminum alloy door and window is automatically lifted upward, thereby facilitating the subsequent unloading process and improving the operating efficiency of the equipment. A spring 1010 is fixedly connected between the contact plate 1011 and the inner top of the C-shaped lifting plate 1008.

[0025] The length of the contact plate 1011 is less than the length of the C-shaped lifting plate 1008. The movement trajectory of the C-shaped lifting plate 1008 contacts the outer side of the welded aluminum alloy door and window. The outer movement trajectory of the support bracket 700 does not contact the outer movement trajectory of the C-shaped lifting plate 1008. The top of the base plate 100 is movably connected to the correction component 1100.

[0026] In practical use, after welding is completed, the drive screw 500 is rotated in the reverse direction, causing the support bracket 700 to slide downwards at an angle. This causes the support bracket 700 to rotate from a horizontal state to an inclined state, which in turn causes the support bracket 700 to move the second fixed plate 1001 downwards at an angle. The bottom of the second fixed plate 1001 then contacts the inclined surface 1006, causing the trigger rod 1005 to rotate counterclockwise along the first rotating shaft 1004. This causes the trigger rod 1005 to rotate the support rod 1007 upwards, which in turn causes the support rod 1007 to rotate the C-shaped lifting plate 1008 upwards. The C-shaped lifting plate 1008 then rotates the contact plate 1011 upwards, causing the top of the contact plate 1011 to contact the bottom of the welded aluminum alloy door / window. This automatically lifts the aluminum alloy door / window upwards, facilitating the subsequent unloading process and improving the equipment's operating efficiency.

[0027] Example 3, as Figures 2-9 As shown, based on Embodiment 2, the correction assembly 1100 includes a second rotating shaft 1101, a first bevel gear 1102, a second bevel gear 1103, a lead screw 1104, a fourth fixing plate 1105, a second sliding groove 1106, a vertical slider 1107, an L-shaped correction plate 1108, and a welding guide plate 1109. The bottom of the drive lead screw 500 is fixedly connected to the second rotating shaft 1101, and a locking device is movably connected between the second rotating shaft 1101 and the drive lead screw 500. Locking is only applied when the support frame 700 is completely horizontal. This allows the rotating shaft 1101 to continue rotating with the motor. The outer side of the rotating shaft 1101 is movably connected to the inside of the support column 300. A bevel gear 1102 is fixedly connected to the bottom outer side of the rotating shaft 1101. Multiple lead screws 1104 are movably connected inside the support column 300. A bevel gear 1103 is fixedly connected to one end of each lead screw 1104 near the bevel gear 1102. The bevel gear 1103 meshes with the bevel gear 1102. The other end of each lead screw 1104 is movably connected to a fixed... Fixed plate 4 1105 is fixedly connected at its bottom to the top of base plate 100. Slide groove 2 1106 is fixedly connected to the rear bottom of fixed plate 4 1105. Limit microswitches are fixedly connected to both ends of slide groove 2 1106 to prevent vertical slider 1107 from moving beyond its limit. Vertical slider 1107 is movably connected inside slide groove 2 1106. L-shaped straightening plate 1108 is fixedly connected to the top of vertical slider 1107. An elastic buffer pad is fixedly connected to the inner surface of L-shaped straightening plate 1108. An L-shaped correction plate 1108 is set up so that the inner surface of the L-shaped correction plate 1108 contacts both sides of the aluminum alloy workpiece 800, thereby correcting the slight horizontal displacement of the aluminum alloy workpiece 800 by the L-shaped correction plate 1108, making the subsequent welding process smoother. A welding guide plate 1109 is fixedly connected to the inner side of the L-shaped correction plate 1108. The welding guide plate 1109 is set up so that the welding gun head of the welding robot arm 200 will not deviate during the welding process, and at the same time, it blocks the strong light generated by welding.

[0028] The bottom surface of the welding guide plate 1109 does not contact the surface of the aluminum alloy workpiece 800, and a weld guide line is provided at the center of the welding guide plate 1109. The thread length of the lead screw 1104 is less than the length of the slide groove 1106.

[0029] In practical use, when the drive screw 500 rotates, it drives the rotating shaft 1101 to rotate, which in turn drives the bevel gear 1102 to rotate. The bevel gear 1102 then drives the bevel gear 1103 to rotate, which in turn drives the screw 1104 to rotate. The screw 1104 then drives the vertical slider 1107 to move inward along the slide groove 1106. This causes the vertical slider 1107 to move the L-shaped straightening plate 1108 inward, bringing the inner surface of the L-shaped straightening plate 1108 into contact with both sides of the aluminum alloy workpiece 800. This corrects any slight horizontal misalignment of the aluminum alloy workpiece 800, making the subsequent welding process smoother.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
