Description

A smart automated production line for aluminum alloy doors and windows and its production method Technical Field

[0001] This invention belongs to the field of door and window manufacturing technology, specifically an intelligent automatic production line for aluminum alloy doors and windows and its production method. Background Technology

[0002] Aluminum alloy doors and windows typically refer to doors and windows made of frames composed of multiple aluminum alloy rods and fillers such as glass. They are aesthetically pleasing, have excellent sealing properties, and are highly strong, making them widely used in the construction industry. To improve processing efficiency, aluminum alloy doors and windows are generally manufactured using an assembly line approach, with multiple workstations handling the process. This includes material preparation, profile cutting, assembly, welding, surface treatment, installation of accessories, quality inspection, cleaning, and packaging for shipment.

[0003] A patent with publication number CN113695763B discloses an aluminum alloy door and window processing production line. In this patent, a conveyor belt moves the cleaning component to a spraying device. A sliding component drives a sliding plate to slide the cleaning component towards the aluminum alloy door and window. Then, a lifting component drives the cleaning component to slide vertically towards the aluminum alloy door and window until the cleaning component comes into contact with the side of the aluminum alloy door and window. Next, the sliding component drives the sliding plate to move the cleaning component back and forth, so that the cleaning component moves back and forth to wipe the corresponding side of the aluminum alloy door frame. Combined with the rinsing of the spraying device, it helps to clean away dirt, glue and other impurities on the surface of the aluminum alloy door and window, and improves the cleaning effect to a certain extent.

[0004] The above-mentioned solution still has some problems in practical application. It usually uses a robotic arm to grip an aluminum alloy rod and transport it to the cutting equipment for cutting. After cutting, the robotic arm places the aluminum alloy rod on a conveyor belt and transports it to the splicing and welding station. Operators splice and assemble four or six aluminum alloy rods, and clamp and fix the spliced ​​aluminum alloy rods on the worktable. Then, the welding equipment is used to weld and fix the spliced ​​parts, thereby completing the processing and manufacturing of aluminum alloy doors and windows. However, this aluminum alloy door and window production line not only has low cutting efficiency for aluminum alloy rods, but also, if the electrical, mechanical or control system of the robotic arm malfunctions, it will cause the gripping and cutting operation to be interrupted, and in severe cases, it may even cause safety accidents.

[0005] Therefore, the present invention provides an intelligent automatic production line for aluminum alloy doors and windows and its production method. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides an intelligent automatic production line for aluminum alloy doors and windows, including a fixed frame, baffles are installed on both the front and rear ends of the fixed frame, a support frame is installed on the upper end of the baffles, and an automatic material picking and conveying component is installed in the inner cavity of the fixed frame.

[0008] The automatic material handling and conveying assembly includes four drive rollers installed in the inner cavity of the fixed frame;

[0009] It also includes four support blocks fixed to both sides of the lower end of the fixed frame;

[0010] Two of the drive rollers are rotatably connected to the inner cavity of the fixed frame, and the other two drive rollers are rotatably connected to the four support blocks. Two conveyor belts are externally connected to the four drive rollers, and the four drive rollers are used to support the conveyor belts in a rectangular configuration. One side of the fixed frame is semi-circular, so that the conveyor belts can automatically retract the aluminum alloy rods in coordination with the fixed frame.

[0011] The lower end of the support frame is provided with a pressing and limiting component, and the pressing and limiting component includes a pressing frame that is slidably connected to the lower end of the support frame. One end of the pressing frame is set in a semi-circular arc shape so that the pressing frame cooperates with the fixing frame to form a V-shaped arc opening for receiving an aluminum alloy rod that is externally conveyed into the inner cavity of the fixing frame.

[0012] Preferably, two grooves are formed on both sides of the upper end face of the support frame, and a tension spring is fixedly connected to the bottom of the inner cavity of the two grooves. A T-shaped sliding column is fixedly connected to one end of the tension spring, and the T-shaped sliding column is slidably connected to the support frame. The lower end of the T-shaped sliding column is fixedly connected to the pressing frame. Multiple transmission grooves are formed on the lower end face of the pressing frame, and rollers are rotatably connected to the inner cavity of the multiple transmission grooves, so that the pressing frame cooperates with the rollers to press the aluminum alloy rod, thereby achieving stability when the aluminum alloy rod is conveyed and moved.

[0013] Preferably, a support plate is installed on the upper end face of the support frame, and an electric push rod is installed on the upper end face of the support plate. The piston rod end of the electric push rod is fixedly connected to a cutting and grinding adjustment component, which is used to adjust the cutting spacing according to the aluminum alloy doors and windows to be processed, and to perform grinding treatment on the cut.

[0014] Preferably, the cutting and grinding adjustment assembly includes an I-shaped push frame installed at the piston rod end of the electric push rod, and the I-shaped push frame has storage slots inside both ends. A bidirectional threaded rod is rotatably installed in the inner cavity of the storage slot. A telescopic rod is threadedly connected to the outside of the bidirectional threaded rod. A driven bevel gear is fixedly connected to the outside of the bidirectional threaded rod. A transmission bevel gear is meshed with the driven bevel gear. A crank handle is fixedly connected to one end of the transmission bevel gear, and the crank handle is rotatably connected to the I-shaped push frame.

[0015] Preferably, an L-shaped limiting frame is installed on one side of the I-shaped push frame, which is used to drive the I-shaped push frame to move the L-shaped limiting frame downward to achieve contact and limiting of the aluminum alloy rod. A fixing block is fixedly connected to one end of the telescopic rod, and a rotating shaft is rotatably connected to the inner cavity of the fixing block. A motor is fixedly connected to the lower end of the rotating shaft. A grinding disc is installed at the output shaft end of the motor located at the L-shaped limiting frame, and a cutting blade is installed at the output shaft end of the motor located on the other side of the I-shaped push frame.

[0016] Preferably, the rotating shaft is fixedly connected to a first fixed plate outside the inner cavity of the fixed block. A first torsion spring is fixedly connected to the lower end of the first fixed plate, and one end of the first torsion spring is fixedly connected to the inner wall of the fixed block. A rotating block is fixedly connected to the upper end of the rotating shaft, which is used to rotate the rotating shaft to drive the motor and the cutting blade and grinding disc to adjust the angle so that the cutting blade and grinding disc can cut and grind the aluminum alloy rod.

[0017] Preferably, a traction rope is fixedly connected to the lower end of the rotating block, and two sets of limiting sleeves are symmetrically installed on one side of the I-shaped push frame, with each set consisting of two limiting sleeves. Two synchronous motors are installed inside the I-shaped push frame, and one end of the traction rope passes through the limiting sleeve and is fixedly connected to the output shaft end of the synchronous motor. This is used to wind up the traction rope to pull the rotating block and drive the motor to rotate 260 degrees, thereby adjusting the cutting angle of the aluminum alloy rod.

[0018] Preferably, the conveyor belt has multiple through grooves evenly arranged on its outer side, and each through groove has a rotating groove on its inner wall. A cylinder is rotatably connected to the inner cavity of the rotating groove, and a stop block is fixedly connected to the outside of the cylinder. The conveyor belt drives the stop block to move so that when the stop block moves to the semi-circular arc of the fixed frame, it collects the aluminum alloy rod conveyed from the outside and puts it into the inner cavity of the fixed frame. The upper end of the stop block is semi-circular arc-shaped and is used to fit against the surface of the aluminum alloy rod for flipping and storing it into the through groove. Two second fixed discs are fixedly connected to the cylinder outside the inner cavity of the rotating groove, and a second torsion spring is fixedly connected to one end face of the two second fixed discs. The second torsion spring is fixedly connected to the inner wall of the rotating groove.

[0019] A smart automated production method for aluminum alloy doors and windows, applied to a smart automated production line for aluminum alloy doors and windows, includes the following steps:

[0020] S1. Preparation: The aluminum alloy profile is transported to the cutting station by the conveyor belt. Then, the aluminum alloy profile is collected by the automatic material handling and conveying component and transported to the bottom of the cutting and grinding equipment.

[0021] S2. Cutting and Grinding Work: According to the shape and size requirements of aluminum alloy doors and windows, the alloy profiles are cut. At the same time, the cutting and grinding angle of the cutting and grinding equipment is adjusted according to the shape of the aluminum alloy doors and windows. Then, the cutting and grinding equipment is driven to move downward to cut the aluminum alloy profiles conveyed below. At the same time, the cut edges are ground to improve the smoothness of the cut edges.

[0022] S3. Splicing and Fixing Work: The cut and polished aluminum alloy profiles are conveyed into the conveyor belt through the automatic material handling and conveying assembly. The conveyor belt then transports the cut and polished aluminum alloy profiles to the splicing and fixing station. Operators splice the cut and polished aluminum alloy profiles to form the shape of doors and windows. At the same time, the clamps at the splicing and fixing station are used to clamp and fix them. Then, the splicing and fixing equipment is used to weld and fix them, thus completing the processing and manufacturing line work of aluminum alloy doors and windows.

[0023] Preferably, the automatic material handling and conveying component in S1 can be adjusted according to the processing efficiency to receive multiple aluminum alloy profiles simultaneously, thereby improving the efficiency of cutting and processing.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The intelligent automatic production line for aluminum alloy doors and windows described in this invention uses a drive cutting and grinding adjustment component to move fixed blocks away from each other, thereby adjusting according to the length of the aluminum alloy rod. After adjustment, an electric push rod drives the cutting and grinding adjustment component downward, enabling the cutting blade to cut the aluminum alloy rod, while the grinding disc grinds the cut edges. This prevents the aluminum alloy rod from being directly spliced ​​and welded without grinding, which could easily cause burrs from cutting, resulting in porosity and holes in the weld, leading to the aluminum alloy doors and windows being prone to damage from air bubbles after prolonged use. The breakage of welded joints in holes and openings affects the service life of aluminum alloy doors and windows. While the I-shaped pusher moves downward, it also pushes the pressing frame to press the aluminum alloy rod, ensuring the stability of the aluminum alloy rod during movement and improving the cutting accuracy. This solves the problem that existing aluminum alloy door and window production lines cannot improve the efficiency of aluminum alloy rod cutting and cannot adapt to the preparation and processing of aluminum alloy doors and windows of different sizes because it is inconvenient to perform cyclic cutting of aluminum alloy rods and adjust according to different lengths of aluminum alloy rods.

[0026] 2. The intelligent automatic production line for aluminum alloy doors and windows described in this invention starts a synchronous motor, causing the output shaft of the synchronous motor to drive the traction rope to wind up. This traction rope then pulls a rotating block to rotate, which in turn drives a rotating shaft to rotate. During this rotation, the rotating shaft drives a first fixed disc to rotate, which in turn drives a first torsion spring to twist. This causes the rotating shaft to drive a mounting motor to rotate, which in turn drives the cutting blade and grinding disc to rotate synchronously. The traction rope pulls the rotating block to rotate the rotating shaft, and simultaneously drives the mounting motor to rotate 260 degrees. This allows for synchronous adjustment according to the required cutting and grinding angles of the aluminum alloy rod. This solves the problem in existing aluminum alloy door and window production lines where the cutting blade angle cannot be adjusted according to the angle of the aluminum alloy rod to be cut, resulting in the inability to cut and process aluminum alloy rods of different shapes when producing aluminum alloy doors and windows.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] Example 1

[0045] As shown in Figures 1 to 10, the intelligent automatic production line for aluminum alloy doors and windows according to the embodiments of the present invention includes a fixed frame 1, baffles 2 are installed on both the front and rear ends of the fixed frame 1, a support frame 3 is installed on the upper end of the baffles 2, and an automatic material picking and conveying component 6 is installed in the inner cavity of the fixed frame 1.

[0046] Furthermore, the automatic material handling and conveying assembly 6 includes four drive rollers 67 installed in the inner cavity of the fixed frame 1;

[0047] It also includes four support blocks 69 fixed to both sides of the lower end of the fixed frame 1;

[0048] Two of the drive rollers 67 are rotatably connected to the inner cavity of the fixed frame 1, and the other two drive rollers 67 are rotatably connected to four support blocks 69. The four drive rollers 67 are externally connected to two conveyor belts 61, and the four drive rollers 67 are used to support the conveyor belts 61 in a rectangular arrangement. One side of the fixed frame 1 is in a semi-circular arc shape so that the conveyor belts 61 cooperate with the fixed frame 1 to automatically retract the aluminum alloy rods 20.

[0049] The lower end of the support frame 3 is provided with a pressing limit component 7, and the pressing limit component 7 includes a pressing frame 74 slidably connected to the lower end of the support frame 3. One end of the pressing frame 74 is set in a semi-circular arc shape so that the pressing frame 74 cooperates with the fixed frame 1 to form a V-shaped arc opening for receiving the aluminum alloy rod 20 that is externally transported into the inner cavity of the fixed frame 1.

[0050] Specifically, in the existing technology for manufacturing aluminum alloy doors and windows, a robotic arm is typically used to clamp an aluminum alloy rod, and then a cutting device is used to cut both ends of the rod. The cut rod is then placed on a conveyor belt and transported to the splicing and welding station, where four cut aluminum alloy rods are spliced ​​together. The spliced ​​rods are then clamped and fixed on a workbench, and the spliced ​​joints are welded together using welding equipment to complete the manufacturing of the aluminum alloy doors and windows. However, this type of aluminum alloy door and window production line not only has low efficiency in cutting aluminum alloy rods, but also, if the electrical, mechanical, or control system of the robotic arm malfunctions, the clamping and cutting operation can be interrupted, and in severe cases, even cause safety accidents.

[0051] This invention installs a fixed frame 1 at the tail end of an external aluminum alloy rod 20 conveyor belt, then drives a transmission roller 67 to rotate a conveyor belt 61, which receives the aluminum alloy rod 20 from the external conveyor belt and transports it into the inner cavity of the fixed frame 1. While the conveyor belt 61 receives the aluminum alloy rod 20 and transports it into the inner cavity of the fixed frame 1, the aluminum alloy rod 20 slides into a V-shaped opening formed by a pressing frame 74 and the fixed frame 1, and slides between the conveyor belt 61 and the pressing frame 74. Simultaneously, the aluminum alloy rod 20 pushes the pressing frame 74 upwards, causing the pressing frame 74 to press down on the aluminum alloy rod 20, ensuring the stability of the aluminum alloy rod 20 during transport and preventing deviation during transport by the conveyor belt 61. After multiple aluminum alloy rods 20 are transported into the inner cavity of the fixed frame 1, they are simultaneously cut using a cutting device, thus completing the processing and preparation of the aluminum alloy door and window workpiece and solving the aforementioned problems.

[0052] As shown in Figures 1, 2, and 9, two grooves 72 are provided on both sides of the upper end face of the support frame 3, and tension springs 73 are fixedly connected to the bottom of the inner cavity of the two grooves 72. A T-shaped sliding column 71 is fixedly connected to one end of the tension spring 73, and the T-shaped sliding column 71 is slidably connected to the support frame 3. The lower end of the T-shaped sliding column 71 is fixedly connected to the pressing frame 74. Multiple transmission grooves 75 are provided on the lower end face of the pressing frame 74, and rollers 76 are rotatably connected to the inner cavity of the multiple transmission grooves 75, so that the pressing frame 74 cooperates with the rollers 76 to press the aluminum alloy rod 20, thereby achieving the stability of the aluminum alloy rod 20 during transport and movement.

[0053] Specifically, when the aluminum alloy rod 20 is transported into the inner cavity of the fixed frame 1 by the conveyor belt 61, the aluminum alloy rod 20 pushes the pressing frame 74 upward, causing the pressing frame 74 to push the T-shaped sliding column 71 upward. At the same time, the T-shaped sliding column 71 pulls the tension spring 73 to expand. Then, the tension of the tension spring 73 pulls the T-shaped sliding column 71 downward, while pushing the pressing frame 74 to drive the roller 76 to press and fix the aluminum alloy rod 20. This ensures that the aluminum alloy rod 20 maintains high stability during the transport process and also ensures the stability of the aluminum alloy rod 20 when the cutting equipment cuts it, preventing movement and deviation that could cause deviations in the cutting angle and affect the processing quality of the aluminum alloy doors and windows.

[0054] As shown in Figures 1, 2 and 3, a support plate 4 is installed on the upper end of the support frame 3, and an electric push rod 5 is installed on the upper end of the support plate 4. The piston rod end of the electric push rod 5 is fixedly connected to a cutting and grinding adjustment component 8, which is used to adjust the cutting spacing according to the aluminum alloy doors and windows to be processed, and to perform grinding treatment on the cut.

[0055] As shown in Figures 2, 3, and 8, the cutting and grinding adjustment assembly 8 includes an I-shaped push frame 81 installed at the piston rod end of the electric push rod 5. The I-shaped push frame 81 has a storage groove 82 inside both ends. A bidirectional threaded rod 84 is rotatably installed inside the storage groove 82. A telescopic rod 85 is threadedly connected to the outside of the bidirectional threaded rod 84. A driven bevel gear 86 is fixedly connected to the outside of the bidirectional threaded rod 84. A transmission bevel gear 87 is meshed with the driven bevel gear 86. A crank handle 83 is fixedly connected to one end of the transmission bevel gear 87. The crank handle 83 is rotatably connected to the I-shaped push frame 81.

[0056] As shown in Figures 2, 3, and 8, an L-shaped limiting frame 19 is installed on one side of the I-shaped push frame 81. This L-shaped limiting frame 19 is used to move the I-shaped push frame 81 downwards to achieve contact and limiting of the aluminum alloy rod 20. A fixing block 9 is fixedly connected to one end of the telescopic rod 85. A rotating shaft 12 is rotatably connected to the inner cavity of the fixing block 9. A motor 13 is fixedly connected to the lower end of the rotating shaft 12. A grinding disc 15 is installed on the output shaft end of the motor 13 located at the L-shaped limiting frame 19, while a cutting blade 14 is installed on the output shaft end of the motor 13 located on the other side of the I-shaped push frame 81.

[0057] Specifically, when cutting the fixed frame 1 conveyed by the conveyor belt 61, the crank handle 83 is turned to rotate the transmission bevel gear 87, which in turn meshes with the driven bevel gear 86 to rotate, thereby driving the bidirectional threaded rod 84 to rotate. During the rotation of the bidirectional threaded rod 84, the threaded transmission telescopic rod 85 slides and moves away from each other in the inner cavity of the receiving groove 82, thereby causing the telescopic rod 85 to drive the fixed block 9 to move away from each other, thus adjusting according to the length of the aluminum alloy rod 20. After the adjustment is completed, the electric push rod 5 drives the I-shaped push frame 81 to move downward, and the I-shaped push frame 81 drives the telescopic rod 85 to move downward, while simultaneously driving the fixed block 9 to move downward. The fixed block 9 drives the mounting motor 13 to move downward, and the mounting motor 13 drives the cutting blade 14 and the grinding disc 15 to move downward synchronously. Then, the mounting motor 13 is started to drive the cutting blade 14 and the grinding disc 15 to rotate. Thus, during the process of the mounting motor 13 driving the cutting blade 14 and the grinding disc 15 to move downward, the cutting blade 14 can be used to rotate. The aluminum alloy rod 20 is cut, and the grinding disc 15 grinds the cut edges of the aluminum alloy rod 20 after cutting. This prevents the aluminum alloy rod 20 from being directly spliced ​​and welded without grinding, as the burrs generated during cutting can easily cause air holes and voids in the weld. This results in poor sealing during the later installation and use of aluminum alloy doors and windows, and the presence of voids and air holes in the weld can easily lead to breakage at the weld joint after long-term use, affecting the service life of the aluminum alloy doors and windows. While the driving I-shaped push frame 81 moves downward, it pushes the pressing frame 74 to press the aluminum alloy rod 20, ensuring the stability of the aluminum alloy rod 20 during movement and improving the cutting accuracy. This solves the problem that existing aluminum alloy door and window production lines cannot improve the efficiency of aluminum alloy rod cutting and processing due to the inconvenience of cyclic cutting of aluminum alloy rods and the inability to adjust according to different lengths of aluminum alloy rods, and cannot adapt to the processing of aluminum alloy doors and windows of different sizes.

[0058] Example 2

[0059] As shown in Figures 2, 7 and 8, the rotating shaft 12 is located outside the inner cavity of the fixed block 9 and is fixedly connected to the first fixed plate 10. The lower end of the first fixed plate 10 is fixedly connected to the first torsion spring 11, and one end of the first torsion spring 11 is fixedly connected to the inner wall of the fixed block 9. The upper end of the rotating shaft 12 is fixedly connected to the rotating block 16, which is used to rotate the rotating shaft 12 to drive the motor 13 and the cutting blade 14 and the grinding disc 15 to adjust the angle so that the cutting blade 14 and the grinding disc 15 can cut and grind the aluminum alloy rod 20.

[0060] As shown in Figures 2 and 7 to 10, a traction rope 17 is fixedly connected to the lower end of the rotating block 16. Two sets of limiting sleeves 18 are symmetrically installed on one side of the I-shaped push frame 81, and each set consists of two limiting sleeves 18. Two synchronous motors 21 are installed inside the I-shaped push frame 81. One end of the traction rope 17 passes through the limiting sleeve 18 and is fixedly connected to the output shaft end of the synchronous motor 21. The traction rope 17 is used to wind up the traction rope 17 to pull the rotating block 16 and drive the motor 13 to rotate 260 degrees, thereby realizing the cutting angle adjustment of the aluminum alloy rod 20.

[0061] Specifically, when it is necessary to adjust the cutting angle of the aluminum alloy rod 20, the synchronous motor 21 is started, and the output shaft of the synchronous motor 21 drives the traction rope 17 to wind up. Then, the traction rope 17 pulls the rotating block 16 to rotate. At the same time, the rotating block 16 drives the rotating shaft 12 to rotate. During the rotation of the rotating shaft 12, it drives the first fixed plate 10 to rotate. At the same time, the first fixed plate 10 drives the first torsion spring 11 to twist, thereby causing the rotating shaft 12 to drive the mounting motor 13 to rotate. This, in turn, drives the cutting blade 14 and the grinding disc 15 to rotate synchronously. The traction rope 17 can pull the rotating block 16 to drive the rotating shaft 12 to rotate, and at the same time drive the mounting motor 13 to rotate 260 degrees. Thus, the cutting angle and grinding angle of the aluminum alloy rod 20 can be adjusted synchronously according to the needs. This solves the problem that existing aluminum alloy door and window production lines cannot adjust the angle of the cutting blade according to the angle to be cut when cutting aluminum alloy rods for aluminum alloy door and window production. This results in the inability to cut and process aluminum alloy rods when producing aluminum alloy door and window rods of different shapes.

[0062] As shown in Figures 1, 4 to 6, multiple through grooves 62 are evenly arranged on the outside of the conveyor belt 61, and a rotating groove 65 is opened on the inner wall of each through groove 62. A cylinder 64 is rotatably connected to the inner cavity of the rotating groove 65. A stop block 63 is fixedly connected to the outside of the cylinder 64. The conveyor belt 61 drives the stop block 63 to move so that when the stop block 63 moves to the semi-circular arc of the fixed frame 1, it collects the aluminum alloy rod 20 conveyed from the outside and puts it into the inner cavity of the fixed frame 1. The upper end of the stop block 63 is set in a semi-circular arc shape to fit against the surface of the aluminum alloy rod 20 and flip it to be stored in the through groove 62. Two second fixed disks 66 are fixedly connected to the cylinder 64 outside the inner cavity of the rotating groove 65, and a second torsion spring 68 is fixedly connected to one end face of the two second fixed disks 66. The second torsion spring 68 is fixedly connected to the inner wall of the rotating groove 65.

[0063] Specifically, by installing the fixed frame 1 at the tail end of the external aluminum alloy rod 20 conveyor belt, and then driving the transmission roller 67 to rotate the conveyor belt 61, the conveyor belt 61 drives the stop block 63 to move synchronously. When the stop block 63 moves to the semi-circular arc of the fixed frame 1, it can pick up the aluminum alloy rod 20 conveyed by the external conveyor belt, thereby actuating the aluminum alloy rod 20 and driving it into the inner cavity of the fixed frame 1 for movement. At the same time, the cutting blade 14 and the grinding disc 15 are used to cut the aluminum alloy rod 20 driven by the stop block 63, and the cut is ground. This solves the problem that existing aluminum alloy door and window production lines cannot cyclically pick up and transport aluminum alloy rods for aluminum alloy door and window production, and cannot cut and grind them during the transport process. This results in the need to use a robotic arm to pick up aluminum alloy rods one by one and transport them to the cutting equipment for cutting, which is not only inefficient, but also affects the subsequent assembly and manufacturing of aluminum alloy doors and windows.

[0064] A smart automated production method for aluminum alloy doors and windows, applied to a smart automated production line for aluminum alloy doors and windows, includes the following steps:

[0065] S1. Preparation: The aluminum alloy profile is transported to the cutting station by the conveyor belt. Then, the aluminum alloy profile is collected by the automatic material handling and conveying component and transported to the bottom of the cutting and grinding equipment.

[0066] S2. Cutting and Grinding Work: According to the shape and size requirements of aluminum alloy doors and windows, the alloy profiles are cut. At the same time, the cutting and grinding angle of the cutting and grinding equipment is adjusted according to the shape of the aluminum alloy doors and windows. Then, the cutting and grinding equipment is driven to move downward to cut the aluminum alloy profiles conveyed below. At the same time, the cut edges are ground to improve the smoothness of the cut edges.

[0067] S3. Splicing and Fixing Work: The cut and polished aluminum alloy profiles are conveyed into the conveyor belt through the automatic material handling and conveying assembly. The conveyor belt then transports the cut and polished aluminum alloy profiles to the splicing and fixing station. Operators splice the cut and polished aluminum alloy profiles to form the shape of doors and windows. At the same time, the clamps at the splicing and fixing station are used to clamp and fix them. Then, the splicing and fixing equipment is used to weld and fix them, thus completing the processing and manufacturing line work of aluminum alloy doors and windows.

[0068] In this embodiment, the automatic material handling and conveying component in S1 can be adjusted according to the processing efficiency to receive multiple aluminum alloy profiles simultaneously, thereby improving the efficiency of cutting and processing.

[0069] The working principle is as follows: the fixed frame 1 is installed at the tail end of the external aluminum alloy rod 20 conveyor belt, and then the drive roller 67 drives the conveyor belt 61 to rotate, and the conveyor belt 61 drives the stop block 63 to move synchronously. When the stop block 63 moves to the semi-circular arc of the fixed frame 1, it can pick up the aluminum alloy rod 20 conveyed by the external conveyor belt, thereby actuating the aluminum alloy rod 20 and driving it into the inner cavity of the fixed frame 1 for movement.

[0070] When the aluminum alloy rod 20 is transported into the inner cavity of the fixed frame 1 by the conveyor belt 61, the aluminum alloy rod 20 pushes the pressing frame 74 upward, and the pressing frame 74 pushes the T-shaped sliding column 71 upward. At the same time, the T-shaped sliding column 71 pulls the tension spring 73 to expand. Then, the tension of the tension spring 73 pulls the T-shaped sliding column 71 downward, and at the same time, pushes the pressing frame 74 to drive the roller 76 to press and fix the aluminum alloy rod 20. This ensures that the aluminum alloy rod 20 maintains high stability during the transportation process. It also ensures the stability of the aluminum alloy rod 20 when the cutting equipment cuts it, preventing movement and deviation, which would cause deviation in the cutting angle and affect the processing quality of aluminum alloy doors and windows.

[0071] When cutting the fixed frame 1 conveyed by the conveyor belt 61, the crank handle 83 is turned to rotate the transmission bevel gear 87, which in turn meshes with the driven bevel gear 86 to rotate, thereby driving the bidirectional threaded rod 84 to rotate. During the rotation of the bidirectional threaded rod 84, the threaded transmission telescopic rod 85 slides and moves away from each other in the inner cavity of the receiving groove 82, thereby causing the telescopic rod 85 to drive the fixed block 9 to move away from each other, thus adjusting according to the length of the aluminum alloy rod 20. After the adjustment is completed, the electric push rod 5 drives the I-shaped push frame 81 to move downward, and the I-shaped push frame 81 drives the telescopic rod 85 to move downward, while simultaneously driving the fixed block 9 to move downward. The fixed block 9 drives the mounting motor 13 to move downward, and the mounting motor 13 drives the cutting blade 14 and the grinding disc 15 to move downward synchronously. Then, the mounting motor 13 is started to drive the cutting. As the cutting blade 14 and grinding disc 15 rotate, and the motor 13 drives the cutting blade 14 and grinding disc 15 to move downwards, the cutting blade 14 can cut the aluminum alloy rod 20, while the grinding disc 15 grinds the cut edges of the aluminum alloy rod 20. This prevents the aluminum alloy rod 20 from being directly spliced ​​and welded without grinding, as the burrs generated during cutting can easily cause air holes and pores in the weld, resulting in poor sealing effect when the aluminum alloy doors and windows are installed and used later. Furthermore, the presence of pores and air holes in the weld can easily lead to weld breakage at the weld joints after long-term use, affecting the service life of the aluminum alloy doors and windows. While the I-shaped push frame 81 moves downwards, the I-shaped push frame 81 will push the pressing frame 74 to press the aluminum alloy rod 20, ensuring the stability of the aluminum alloy rod 20 during movement and improving the cutting accuracy.

[0072] When it is necessary to adjust the cutting angle of the aluminum alloy rod 20, the synchronous motor 21 is started, and the output shaft of the synchronous motor 21 drives the traction rope 17 to wind up. Then, the traction rope 17 pulls the rotating block 16 to rotate. At the same time, the rotating block 16 drives the rotating shaft 12 to rotate. During the rotation of the rotating shaft 12, it drives the first fixed plate 10 to rotate. At the same time, the first fixed plate 10 drives the first torsion spring 11 to twist, thereby causing the rotating shaft 12 to drive the mounting motor 13 to rotate. This, in turn, drives the cutting blade 14 and the grinding disc 15 to rotate synchronously. The traction rope 17 can pull the rotating block 16 to drive the rotating shaft 12 to rotate, and at the same time drive the mounting motor 13 to rotate 260 degrees. Thus, the cutting angle and grinding angle of the aluminum alloy rod 20 can be adjusted synchronously according to the needs.
