Description

Technical Field

[0001] This invention belongs to the technical field of aluminum alloy door and window welding equipment, specifically relating to an aluminum alloy insulated door and window and its welding equipment. Background Technology

[0002] Aluminum alloy insulated doors and windows are energy-saving building doors and windows products assembled with aluminum alloy profiles as the main frame, and thermal break strips filled inside the profile cavity to form a thermal break structure. They are combined with insulated tempered glass, sealing strips, and hardware transmission components. The aluminum alloy insulated door and window welding equipment is a special welding tooling equipment for processing thermal break aluminum doors and windows. It is mainly used for splicing and welding the corners of thermal break aluminum alloy profiles, replacing the traditional corner bracket assembly process, realizing a seamless connection of the four corners of the door and window frame, and improving the sealing performance, structural strength and appearance flatness of the doors and windows.

[0003] When operating existing aluminum alloy insulated door and window welding equipment, operators need to manually adjust the window frame position to align the corners with the welding area. For large-sized aluminum alloy window frames, their weight and dimensions are significant, making manual handling and alignment difficult, labor-intensive, and inefficient over long periods. Furthermore, existing equipment often uses a single set of external clamping components to fix the window frame corners to ensure splicing accuracy. The placement of the frame strips relies entirely on visual calibration by the operator, which can easily lead to operational errors during prolonged continuous operation. This results in uneven corner splicing gaps and misalignment of profiles, causing a decrease in the fitting accuracy of the window frame corners, directly affecting the quality of the welded product and the thermal insulation and sealing performance of the doors and windows. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum alloy insulated door and window with a simple structure and reasonable design, and its welding equipment, in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A welding device for aluminum alloy insulated doors and windows includes a frame, a frame table for supporting the window frame being processed, a controller fixedly connected to the side surface of the frame (including but not limited to PLC, microcontroller, etc.), feet fixedly connected to the lower surface of the frame, and a support device on the upper surface of the frame. The support device includes a first pen-shaped cylinder fixed to the upper surface of the frame, a crossbar fixedly connected to the piston rod of the first pen-shaped cylinder, and drive mechanisms at both ends of the crossbar. A longitudinal drive is mounted on the right drive mechanism, and an assembly component is provided on the sliding part of the longitudinal drive. A laser welder is mounted on the assembly component. The right drive mechanism cooperates with the longitudinal drive to move the laser welder, realizing the welding operation of the window frame corners. The surface of the crossbar... A bracket is fixedly connected, a second motor is fixedly connected to the upper surface of the bracket, a second gear is fixedly connected to the output end of the second motor, a guide ring is fixedly connected to the lower surface of the bracket, a frame is rotatably connected to the surface of the guide ring, a third gear matching the second gear is fixedly connected to the inner wall of the frame, a connecting frame is fixedly connected to the lower surface of the frame, and a clamping device is provided on the lower surface of the connecting frame. Through the cooperation of the second motor, the second gear, and the third gear, the frame is driven when the second motor is working. Under the guidance of the guide ring, the frame drives the connecting frame to rotate, thereby driving the clamping device and the clamped window frame to rotate, thus changing the position of the window frame corners. The controller, the first pen-shaped cylinder, the longitudinal driver, the laser welder, and the second motor are all existing technologies and will not be described in detail here.

[0006] As a further optimization of the present invention, the driving mechanism includes a support plate slidably mounted on a crossbeam. A first mounting bracket is fixedly connected to the surface of the support plate on the left side. A first motor is fixedly connected to the upper surface of the support plate. A circular hole is formed on the surface of the support plate. The output end of the first motor passes through the circular hole and penetrates the support plate. A first gear is fixedly connected to the output end of the first motor. A rack is fixedly connected to the lower surface of the crossbeam. The first gear meshes with the tooth groove of the rack. When the first motor drives the first gear to rotate, the first gear meshes with the rack and drives the support plate to move along the crossbeam, thereby adjusting the position of the support plate. A protective cover is fixedly connected to the side surface of the crossbeam. The first gear and the rack are both located inside the protective cover. A slot is formed on the surface of the protective cover. The output end of the first motor moves through the protective cover through the slot. The protective cover protects the first gear and rack, isolating them from the external environment and improving their stability during use. The first motor is existing technology and will not be described in detail here.

[0007] As a further optimization of the present invention, the longitudinal driver is fixedly connected to the upper surface of the support plate on the right side. The assembly includes a second mounting bracket fixed to the sliding part of the longitudinal driver. A guide rail is fixedly connected to the surface of the second mounting bracket, a slider is slidably connected to the surface of the guide rail, and a fixing frame is fixedly connected to the surface of the slider. The guide rail and the slider guide the movement direction of the fixing frame, so that the fixing frame always moves in a specified direction during the movement. The laser welder is fixedly connected to the fixing frame. A second pen-shaped cylinder is fixedly connected to the second mounting bracket. The piston rod of the second pen-shaped cylinder is fixedly connected to the upper surface of the fixing frame. The second pen-shaped cylinder, in conjunction with the fixing frame, adjusts the position of the laser welder in the vertical direction, so that the range between the laser welder and the corner of the window frame is kept within a suitable welding distance. The second pen-shaped cylinder is prior art and will not be described in detail here.

[0008] As a further optimization of the present invention, the surface of the bracket is provided with a through hole, the output end of the second motor passes through the through hole through the bracket, the output end of the second motor is located inside the frame, and the tooth grooves of the second gear and the third gear mesh.

[0009] As a further optimization of the present invention, the clamping device includes an assembly plate fixed to the lower surface of the connecting frame. A baffle is fixedly connected to the lower surface of the assembly plate, supporting the window frame from the inside, thereby further improving the alignment accuracy of the window frame. A guide frame is fixedly connected to the upper surface of the assembly plate, and a transfer block is slidably connected to the guide frame. The guide frame guides the movement direction of the transfer block, causing it to move along a set straight line, thus improving the movement accuracy of the transfer block. A convex shaft is fixedly connected to the side surface of the transfer block, and a guide plate is provided on the convex shaft. An optical axis is fixedly connected to the inner wall, and a clamping plate is fixedly connected to one end of the optical axis. A rubber block is fixedly connected to the surface of the clamping plate, which replaces the clamping plate in contact with the window frame. This increases the friction between the clamping plate and the window frame while avoiding damage to the window frame caused by the clamping plate making hard contact with the window frame. A thin cylinder is fixedly connected to the lower surface of the assembly plate, and a linkage frame is fixedly connected to the piston rod of the thin cylinder. The linkage frame is fixedly connected to the upper surface of the guide plate. The thin cylinder and the linkage frame work together to drive all the guide plates to move synchronously. The thin cylinder is existing technology and will not be described in detail here.

[0010] As a further optimization of the present invention, the four corners of the assembly plate are provided with clearance grooves to reserve space for the movement of the laser welder. The baffle is J-shaped, and there are four baffles. The four baffles are respectively set on the four sides of the assembly plate, and the four baffles can correspond to the four frame strips of the window frame to ensure the support effect of the window frame. The J-shaped design of the baffles gives the lower end of the baffle a bent part. When the baffle is inserted into the window frame, the bent part ensures that the baffle is smoothly inserted into the inner side of the window frame. The surface of the guide plate is provided with oblique holes, and the convex shaft is slidably connected to the oblique holes. The oblique holes of the guide plate cooperate with the convex shaft so that when the linkage frame drives the guide plate, it simultaneously drives the transfer block to move, so as to pull the optical shaft and the clamping plate to move, so that the clamping plate cooperates with the baffle to clamp the window frame. The optical shaft is slidably connected to the inner wall of the guide frame. The surface of the assembly plate is provided with mounting holes, and the piston rod of the thin cylinder slides through the mounting holes through the assembly plate. The linkage frame is shaped like a grid.

[0011] As a further optimization of the present invention, a grinding device is provided on the first mounting bracket. The grinding device includes a housing fixed to the surface of the first mounting bracket. A third motor is fixedly connected to the lower inner wall of the housing. An isolation area is formed by the cooperation between the housing and the mounting bracket to protect the third motor. A rotating shaft is fixedly connected to the output end of the third motor. A grinding wheel is detachably mounted on the surface of the rotating shaft. The grinding wheel rotates under the drive of the third motor and the rotating shaft to grind the welding positions at the corners of the window frame. Connecting plates are fixedly connected to both sides of the housing. A dust collection hood is fixedly connected to the lower surface of the plate, and an electrostatic lint strip is fixedly connected to the lower surface of the dust collection hood. A dust collection box is fixedly connected to the surface of the first mounting bracket. A corrugated pipe is fixedly connected between the dust collection box and the dust collection hood. A collection chamber is detachably installed on the inner wall of the dust collection box. A fan is fixedly connected to the upper surface of the dust collection box. A filter element is detachably installed on the upper inner wall of the dust collection chamber. The filter element can filter the airflow entering the fan, and the filtered dust falls into the collection chamber for easy handling by the operator. The third motor and the fan are existing technologies and will not be described in detail here.

[0012] As a further optimization of the present invention, the output end of the third motor rotates through the lower surface of the outer shell, and the surface of the dust collection hood is provided with a through hole. The dust collection hood is rotatably sleeved on the rotating shaft through the through hole. The dust collection hood is sleeved on the grinding wheel. The dust collection hood and the electrostatic lint strip cooperate to form a shielding structure to shield the dust generated during grinding. The dust collection hood is connected to the inside of the dust collection box through a corrugated pipe. The input end of the fan is connected to the inside of the dust collection box. When the fan works, it generates a negative pressure inside the dust collection box. The negative pressure causes the corrugated pipe to generate suction, thereby sucking up the dust at the dust collection hood.

[0013] As a further optimization of the present invention, the object processed by the welding equipment is a heat-insulating window. The heat-insulating window includes a window frame, which is made of aluminum alloy to ensure the structural strength of the window frame. Three layers of glass with non-equidistant spacing are fixedly connected to the inner wall of the window frame. The glass is coated glass to increase the heat insulation effect of the glass. A spacer is fixedly connected between the three layers of glass. The spacer is made of PA66 or other materials to further increase the heat insulation effect of the heat-insulating window. A positioning frame is detachably installed on the inner wall of the window frame. The positioning frame abuts against the surface of the outermost glass. A buckle is detachably installed on the inner side of the positioning frame. The buckle abuts against the surface of the outermost glass. The inner side wall edge of the positioning frame is chamfered. One end of the buckle is chamfered. The chamfered surface of the buckle abuts against the chamfered surface of the positioning frame. Through the chamfered surfaces of the positioning frame and the buckle, when the user fixes the buckle with screws, the tightening degree of the screws can be adjusted to adjust the squeezing strength of the buckle on the positioning frame, so that the positioning frame and the glass fit tightly together.

[0014] The beneficial effects of this invention are as follows: 1. By coordinating the support and clamping devices, the equipment can automatically adjust the position of the window frame corners during welding. After welding, the unwelded corners on one side of the window frame can be moved to the welding area by rotating the window frame, improving work efficiency. In addition, the window frame is clamped by baffles, clamps, and rubber blocks. While simultaneously clamping the four frame strips, the baffles support the inside of the window frame, improving the splicing accuracy between the window frame corners. This avoids the problems of manual handling of the window frame, which is inefficient during long-term operation and can easily cause misalignment of the window frame corners when placing the frame strips, leading to a decrease in corner fitting accuracy and affecting the welding quality and thermal insulation performance of the window frame.

[0015] 2. By using a grinding device installed on the support device, after the support device and clamping device have completed the corner replacement of the window frame, the grinding device can grind the corners of the window frame that have been welded to ensure the flatness and quality of the corners after welding, so as to facilitate subsequent processing.

[0016] 3. By cooperating with the positioning frame and the fastening strip, the operator can improve the tightness of the fit between the positioning frame, glass and spacer strip when installing the glass, thereby improving the overall sealing performance of the heat-insulating window.

[0028] Please see Figures 10-12The welding equipment processes the insulated window 7, which also includes three layers of non-equidistant glass 72 fixedly connected to the inner wall of the window frame 71. The window frame 71 is made of aluminum alloy to ensure its structural strength. The glass 72 is coated glass to increase its heat insulation effect.

Through the chamfered surfaces of the positioning frame 74 and the retaining strip 75, when the user fixes the retaining strip 75 with screws, the tightening degree of the screws can be adjusted to adjust the compressive strength of the retaining strip 75 on the positioning frame 74, so that the positioning frame 74 and the glass 72 fit tightly together.

[0029] It should be noted that, when using this aluminum alloy insulated window and its welding equipment, the frame strips of the window frame 71 are placed in the processing area of ​​the machine frame 1, and the four frame strips are initially spliced ​​together. Then, the controller 2 is operated to start the equipment.

Under the action of the connecting frame 414, the assembly plate 51 drives the baffle 52 and other structures to move down. The baffle 52 moves down and inserts into the inner side of the window frame 71. When it moves down to the position, the thin cylinder 510 works to lift the linkage frame 511. The linkage frame 511 pulls the guide plate 56. The guide plate 56 drives the convex shaft 55 to move through the inclined hole. The convex shaft 55 moves the transfer block 54 under the action of the inclined hole. The transfer block 54 drives the optical shaft 57 to move. The optical shaft 57 pulls the clamping plate 58 and the rubber block 59 through the guide frame 53. The rubber block 59 abuts against the outer wall of the frame strip and pushes the frame strip. The frame strip is pushed towards the baffle 52. When the frame strip is close to the surface of the baffle 52, the frame strip is clamped by the baffle 52, the clamping plate 58 and the rubber block 59. At the same time, the corners between the four frame strips are fitted together. After bonding, the first motor 432 on the right side drives the first gear 433. The first gear 433 meshes with the rack 434, causing the support plate 431, the longitudinal driver 45, the assembly assembly 46, and the laser welder 47 to move laterally. At the same time, the longitudinal driver 45 moves the laser welder 47 longitudinally. During this process, the second pen-shaped cylinder 465 works to push the fixing frame 464. Under the guidance of the slider 463 and the guide rail 462, the fixing frame 464 moves the laser welder 47 downward, shortening the distance between the laser welder 47 and the window frame 71. When the laser welder 47 gets close to the window frame 71... When the laser welder 47 is at the corner, it emits a laser to weld the corner of the window frame 71. After the welding is completed, the right drive mechanism 43 and the second pen-shaped cylinder 465 drive the laser welder 47 to reset. The longitudinal drive 45 continues to move the laser welder 47 to the other corner on the same side of the window frame 71. When the laser welder 47 moves to the other corner, the drive mechanism 43 and the second pen-shaped cylinder 465 work again to feed the laser welder 47 so that the laser welder 47 welds the other corner. After the welding is completed, the laser welder 47 exits the welding point. After the laser welder 47 exits the welding point, the second motor 49 drives the second gear 410. The second gear 410 meshes with the third gear 413 to drive the frame 412. The frame 412 rotates under the guidance of the guide ring 411. When the frame 412 rotates, it works with the connecting frame 414 to drive the clamping device 5 and the clamped window frame 71 to rotate. After the window frame 71 rotates 180°, the two ends of the window frame 71 are swapped. The welded corner moves out of the welding area, and the unwelded corner enters the welding area. At this time, the laser welder 47 welds the unwelded corner of the window frame 71 based on the above steps. During the welding process, the first motor 432 on the left side, in conjunction with the first gear 433 and rack 434, moves the support plate 431. The support plate 431 moves the first mounting bracket 44, which in turn moves the grinding device 6. During this movement, the third motor 62, in conjunction with the rotating shaft 63, drives the grinding wheel 64 to rotate, and the fan 611 enters the working state. The fan 611 draws air from the dust collection box 69, creating a negative pressure in the dust collection box 69. Under this negative pressure, the bellows 68 and the dust collection hood 66 generate suction, causing the grinding wheel 64 to rotate. When the grinding wheel 64 contacts the welded corner near the window frame 71, it grinds the welded corner. The dust generated by grinding is blocked by the dust collection hood 66 and the electrostatic velvet strip 67. The blocked dust is sucked into the dust collection box 69 through the dust collection hood 66 and the corrugated pipe 68. The airflow mixed with dust enters the dust collection chamber and passes through the filter element 612. The filter element 612 filters the dust in the airflow. The filtered dust falls into the collection chamber 610. During subsequent maintenance, the operator can disassemble the dust collection chamber to clean the dust collected inside. After welding is completed on the other side corner, the grinding device 6 grinds simultaneously. Then, the laser welder 47 moves out of the welding point and resets, and the grinding device 6 moves out of the grinding point and resets. The second motor 49 works again to work with the frame 412, connecting frame 414 and clamping device 5 to replace the window frame 71. After the replacement is completed, the grinding device 6 works again to grind the new welding point. After the second grinding is completed, the grinding device 6 moves out of the grinding point and resets, and the clamping device 5 resets and releases the window frame 71. Then, the first pen-shaped cylinder 41 works to lift the crossbeam 42, which drives the laser welder 47, clamping device 5 and grinding device 6 to lift. When the equipment mechanism is lifted into place, the user can remove the flipped window frame 71 and weld the other side of the window frame 71. After both sides of the corner of the window frame 71 are welded, the window frame 71 can be removed for subsequent assembly. During assembly, the first layer of glass 72, the spacer 73, the second layer of glass 72, the spacer 73, and the third layer of glass 72 are sequentially placed into the window frame 71. After the installation of the third layer of glass 72 is completed, the positioning frame 74 is installed into the window frame 71. The fastener 75 is taken out and placed inside the positioning frame 74 and screws are installed. The screws are gradually tightened. When the screws are tightened, the screws and the fastener 75 press against the positioning frame 74, so that the positioning frame 74 presses against the third layer of glass 72. After the installation of the fastener 75 is completed, the heat-insulating window 7 is sent to the next process for subsequent processing. By cooperating with the support device 4 and the clamping device 5, the equipment can automatically change the position of the corners of the window frame 71 when welding the window frame 71. After the corners of one side of the window frame 71 are welded, the unwelded corners can be moved to the welding area by rotating the window frame 71, improving work efficiency. In addition, the window frame 71 is clamped by the baffle 52, clamping plate 58 and rubber block 59. While clamping the four frame strips of the window frame 71 simultaneously, the baffle 52 supports the inside of the window frame 71, improving the splicing accuracy between the corners of the window frame 71. This avoids the problem of manual handling of the window frame 71, which is inefficient during long-term operation. It also avoids the problem of misalignment of the corners of the window frame 71 when placing the frame strips, which can lead to a decrease in the fitting accuracy of the corners and affect the welding quality and heat insulation performance of the window frame 71. By cooperating with the positioning frame 74 and the fastener 75, the operator can improve the tightness of the fit between the positioning frame 74, the glass 72 and the spacer 73 when installing the glass 72, thereby improving the overall sealing performance of the heat-insulating window 7.
