Description
Technical Field
[0001] This invention relates to the field of door and window manufacturing technology, specifically to an intelligent production device for ultra-low energy consumption door and window components. Background Technology
[0002] As is well known, door and window frames are crucial structural components of doors and windows. The production of door frames typically involves numerous steps, such as drilling, grinding, cutting, and welding. These steps are processed using multiple low-energy, intelligent devices. In the cutting stage, adjacent door frame panels (aluminum alloy) are beveled and then assembled to form an L-shaped weld. In the welding stage, a laser welding head is used to weld the L-shaped weld. Currently, in the welding process of door frame components, only the outer part of the L-shaped weld is typically welded. This is because the inner part of the door frame component is relatively narrow and has bends, making it impossible for existing welding mechanisms to perform welding operations in such confined areas.
[0003] Chinese patent document CN113427155B, authorized on June 24, 2022, entitled "A Multifunctional Welding Equipment under a Protective Atmosphere," includes a housing, a support frame, a heating chamber, a plasma welding torch, a sliding module, an argon arc welding platform, and a control device. The heating chamber is fixedly installed within the support frame. The sliding module is connected above the heating chamber, and the plasma welding torch is mounted on the sliding module. The control device can control the sliding module to extend / retract the plasma welding torch into / out of the heating chamber and adjust the welding displacement of the plasma welding torch in the XYZ directions. The argon arc welding platform is mounted on the support frame. The housing covers the heating chamber and the upper part of the argon arc welding platform, and a protective atmosphere is always maintained within the housing. This patent document addresses the challenge of welding thick plate components by combining argon arc welding for the root pass with automatic plasma arc welding, effectively avoiding incomplete penetration of thick plate components. By concentrating argon arc welding and plasma arc welding within a single argon-filled chamber, the operation steps of root pass-automatic welding are simplified, and the introduction of a protective gas is unnecessary.
[0004] The aforementioned patent document demonstrates the simultaneous welding of opposite sides of a component. In existing technologies, due to the considerable thickness of some high-end door frame panels, welding the L-shaped gaps on the exterior of the door frame panel often results in insufficient weld depth, leading to less than ideal weld strength. Therefore, welding the assembly gaps on the inner surface is necessary to increase the overall weld strength. However, welding the inner surface seams is challenging due to the narrow space within the panel and the L-shaped weld formed after assembly. Summary of the Invention
[0005] The purpose of this invention is to provide an intelligent production device for ultra-low energy consumption door and window components to solve the problems in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent production device for ultra-low energy consumption door and window components, comprising a processing table and a first welding mechanism, the first welding mechanism being used for external welding of the L-shaped weld seam of the component, and a second welding mechanism comprising a laser welding mechanism, a horizontal driving unit, and a triggering mechanism, the laser welding mechanism comprising a sliding seat and a laser welding head rotatably connected to the sliding seat, the horizontal driving unit driving the sliding seat to move horizontally, in the horizontal forward section, the laser welding head facing the inward horizontal weld seam to achieve welding, in the horizontal backward section, the triggering mechanism passively driving the laser welding head to move to align with the inward vertical weld seam to achieve welding.
[0007] The aforementioned intelligent production device for ultra-low energy consumption door and window components has a groove on the processing table, and the direction of the groove is on the same vertical plane as the L-shaped weld formed by the assembly of two components.
[0008] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes a laser welding mechanism comprising a sliding seat, a rotating shaft, and a laser welding head. The sliding seat is slidably connected to the slide groove via a slider, and the sliding seat is U-shaped. The rotating shaft is rotatably connected to the interior of the sliding seat.
[0009] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes a laser welding head mounted on a rotating shaft. Two first torsion springs are sleeved on the rotating shaft, with one end of each first torsion spring fixed to the laser welding head and the other end fixed to one side inside the sliding seat.
[0010] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes a horizontal drive unit comprising an electric push rod, which is fixedly connected to the processing table, and the telescopic end of the electric push rod is fixedly connected to the sliding seat.
[0011] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes a triggering mechanism comprising two protrusions disposed opposite to each other on a laser welding head and two baffles disposed opposite to each other on a processing table. Each protrusion is provided with a ball bearing, and the two baffles are located on the same vertical plane, and each baffle is rotatably connected to the processing table via a rotating shaft.
[0012] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes a laser welding head comprising a base and a body. The base has irregularly shaped grooves on both sides, and the irregularly shaped grooves, from the end closer to the body to the end farther from the body, sequentially include a limiting section, a gradient section, and a holding section.
[0013] In the aforementioned intelligent production device for ultra-low energy consumption door and window components, the limiting segment has the smallest width and is used to insert a pin on the first torsion spring to limit the pin. The gradient segment is a segment whose width gradually increases. One end of the gradient segment is connected to the limiting segment, and the other end is connected to the maintaining segment. The maintaining segment is a segment whose width remains unchanged and is the same as the maximum part of the gradient segment.
[0014] In the aforementioned intelligent production device for ultra-low energy consumption door and window components, one pin of the first torsion spring is inserted into the limiting section, and a long strip-shaped guide groove is provided in the irregular groove. The guide groove extends from the transition section to the holding section and penetrates the base.
[0015] The aforementioned intelligent production device for ultra-low energy consumption door and window components includes an electromagnetic adsorption mechanism on the processing table, which is used to limit and fix the laser welding head.
[0016] In the above technical solution, the present invention provides an intelligent production device for ultra-low energy consumption door and window components. Through the setting of a horizontal drive unit and with the cooperation of a triggering mechanism, the position of the laser welding head can be adjusted. Since only the laser welding head needs to enter, the other drive and transmission mechanisms can be located outside the narrow space, allowing the laser welding head to smoothly enter the narrow space inside the component and weld the L-shaped welds (horizontal welds and vertical welds) inside the component. This not only reduces the difficulty of welding inside the component, but also improves the overall welding strength of the component. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0030] Please refer to Figures 1-9 As shown in the embodiments provided by the present invention, the door frame is generally a rectangular structure, which includes two long-side components and two short-side components. The corner of the rectangle is the connection, i.e., the welding position, between the long-side components and the short-side components. At this position, since the circumferential cross-section of the component itself is generally L-shaped, the connection line between the long-side components and the short-side components is also L-shaped. The L-shaped weld in the embodiments of the present invention refers to this weld. As the name suggests, the L-shaped weld includes a horizontal weld and a vertical weld. The side of the connection line facing outward of the component, which is also away from the processing table 1, is the outside of the L-shaped weld, i.e., the external horizontal weld and external vertical weld referred to below. The side of the connection line facing inward of the component, i.e., directly facing the processing table 1, is the inside of the L-shaped weld, i.e., the internal horizontal weld and internal vertical weld referred to below.
[0031] This invention provides an intelligent production device for ultra-low energy consumption door and window components, including a processing table 1 and a first welding mechanism. The first welding mechanism is used for external welding of the L-shaped weld seam of the component. The device also includes a second welding mechanism, which includes a laser welding mechanism, a horizontal driving unit, and a triggering mechanism. The laser welding mechanism includes a sliding seat 2 and a laser welding head 3 rotatably connected to the sliding seat 2. The horizontal driving unit drives the sliding seat 2 to move horizontally. In the horizontal forward section, the laser welding head 3 faces the inward horizontal weld seam to achieve welding. In the horizontal backward section, the triggering mechanism passively drives the laser welding head 3 to move to align with the inward vertical weld seam to achieve welding.
[0032] Specifically, the processing table 1 is the main structure, which is fixed to a fixed foundation, such as the ground, by a support frame (not shown in the figure). Figure 1 As shown, before welding, the two components (long-side component and short-side component) are first transported to the processing table 1. Then, the cut bevels of the two components are aligned and assembled one by one. At this time, the butt joint formed by the assembly is L-shaped, which is the L-shaped weld in this embodiment (i.e., including horizontal weld and vertical weld). Since some high-end components are relatively thick, when welding the L-shaped weld on the outside of the component, the welding depth is often insufficient, resulting in an unsatisfactory weld strength. Therefore, it is necessary to weld the inner surface of the L-shaped weld to increase the overall weld strength. Thus, the welding operation of the L-shaped weld on the inside and outside of the component is carried out by the first welding mechanism and the second welding mechanism respectively. Specifically, the first welding mechanism (not shown in the figure) is set on the processing table 1. The first welding mechanism is used to perform external welding on the L-shaped weld of the component. The first welding mechanism is preferably a plasma welding gun. During external welding, the action of the plasma welding gun is used to adapt and weld the L-shaped weld on the outside of the component. In this embodiment, the processing table 1 is also provided with a positioning fixture (not shown in the figure). The positioning fixture is used to position the L-shaped weld formed by assembling two components to facilitate the welding operation. Before welding, the L-shaped weld of the two components is positioned by the positioning fixture. In this way, the horizontal weld and vertical weld of the component are aligned, avoiding the misalignment of the weld and the resulting weak welding. The above are all prior art and will not be described in detail.
[0033] The innovation of this embodiment is that a second welding mechanism is provided on the processing table 1. The second welding mechanism preferably includes a laser welding mechanism, a horizontal drive unit, and a triggering mechanism. The laser welding mechanism preferably includes a sliding seat 2 and a laser welding head 3 rotatably connected to the sliding seat 2. The horizontal drive unit drives the sliding seat 2 to move horizontally. In the forward phase of the horizontal movement, the laser welding head 3 is directed toward the internal horizontal weld to achieve welding. In the backward phase of the horizontal movement, the triggering mechanism passively drives the laser welding head 3 to move to align with the internal vertical weld to achieve welding.
[0034] The processing table 1 is provided with a sliding groove 4. The direction of the sliding groove 4 is on the same vertical plane as the L-shaped weld seam formed by the assembly of the two components, so as to ensure that the sliding seat 2 slides horizontally on the sliding groove 4 to weld close to the L-shaped weld seam inside the two components.
[0035] The laser welding mechanism includes a sliding seat 2, a rotating shaft 5, and a laser welding head 3. The sliding seat 2 is slidably connected to the slide groove 4 via a slider, and the sliding seat 2 is U-shaped. The rotating shaft 5 is rotatably connected to the inside of the sliding seat 2. The laser welding head 3 is disposed on the rotating shaft 5. A first torsion spring 6 is sleeved at each end of the rotating shaft 5. One pin of each first torsion spring 6 is located on the laser welding head 3, and the other pin is fixed to the sliding seat 2. In this embodiment, the first torsion spring 6 is initially in a compressed state so that the laser welding head 3 is in an inclined state. That is, the tilting and deflection of the laser welding head 3 exerts a compressive force on the first torsion spring 6, so as to facilitate the welding of the horizontal weld seam inside the two components.
[0036] The horizontal drive unit includes an electric push rod 7, which is fixedly connected to the processing table 1, and the telescopic end of the electric push rod 7 is fixedly connected to the sliding seat 2. In this embodiment, the electric push rod 7 has two displacement strokes: a horizontal forward displacement and a horizontal backward displacement. During the horizontal forward displacement, since the laser welding head 3 is tilted upward and facing the internal horizontal weld, the laser welding head 3 welds the internal horizontal weld of the component. During the horizontal backward displacement, the triggering mechanism passively drives the laser welding head 3 to move to align with the internal vertical weld.
[0037] The triggering mechanism includes two protrusions 8 disposed opposite to each other on the laser welding head 3 and two baffles 9 disposed opposite to each other on the processing table 1. The two baffles 9 are on the same vertical plane, and each baffle 9 is rotatably connected to the processing table 1 via a rotating shaft. Each baffle 9 can rotate forward (towards the internal vertical weld seam) and return to its initial state. Figure 4As shown, a second torsion spring (not shown) is sleeved on the rotating shaft. There is a gap between the two baffles 9, and the gap is divided into a first gap and a second gap from top to bottom. That is, the first gap is located above the second gap. The first gap is away from the processing table 1, and the second gap is close to the processing table 1. The first gap is less than the length of the line connecting the two protrusions 8 away from the laser welding head 3, and the second gap is greater than the length of the line connecting the two protrusions 8 away from the laser welding head 3.
[0038] Specifically, the two protrusions 8 are located at the ends of the laser welding head 3. Their purpose is to allow the two protrusions 8 to press against the two baffles 9 (first gap) when the electric push rod 7 is at the end of the horizontal forward section, forcing the two baffles 9 to rotate synchronously relative to each other until the two protrusions 8 pass through the two baffles 9 (first gap). While the two protrusions 8 are pressing against the two baffles 9 (first gap), the laser welding head 3 maintains its initial state as it passes through the two baffles 9 (first gap), thus reaching the connection point between the horizontal weld and the vertical weld, completing the welding of the horizontal weld. The purpose of the first gap in this embodiment is that after the two protrusions 8 have passed through the two baffles 9 (first gap), the rebound of the second torsion spring allows the two baffles 9 to return to their initial state. This process allows the two protrusions 8 to exit from the rear side of the two baffles 9 (away from the inner vertical weld). The laser welding head 3 moves from one side of the weld seam to the front of the two baffles 9 (towards the internal vertical weld seam), thus limiting the two protrusions 8 and preventing them from being squeezed through the two baffles 9 (first gap). When the electric push rod 7 moves horizontally backward, the two protrusions 8 are forced to slide downward along the vertical sidewalls of the two baffles 9 until the laser welding head 3 is arranged horizontally or basically horizontally. At this time, the two protrusions 8 are aligned with the second gap. The purpose of the second gap is to allow the two protrusions 8 to pass smoothly through the second gap when the electric push rod 7 moves horizontally backward, so that the laser welding head 3 is forced to be parallel to the processing table 1. During the process of the two protrusions 8 being forced to slide downward along the vertical sidewalls of the two baffles 9, the laser welding head 3 is also aligned with the vertical weld seam and welds from top to bottom, thus completing the welding of the bottom of the vertical weld seam.
[0039] In a preferred embodiment, each of the protrusions 8 is provided with a ball bearing. The purpose of providing the ball bearing on the protrusion 8 is to reduce the resistance (i.e., friction) of the protrusion 8 sliding downward on the vertical sidewall of the baffle 9.
[0040] Specifically, during welding, by activating the electric push rod 7, the laser welding head 3 inside the sliding seat 2 is pushed to move horizontally forward on the slide groove 4 to weld the horizontal weld inside the component. When the two protrusions 8 on the laser welding head 3 abut against the two baffles 9 (first interval), since the first interval is less than the length of the line connecting the two protrusions 8 away from the end of the laser welding head 3, the laser welding head 3 maintains its initial angle and squeezes through the two baffles 9 (first interval), thereby completing the welding of the horizontal weld. That is, the laser welding head 3 is aligned with the connection between the horizontal weld and the vertical weld, thereby completing the stroke of the horizontal forward section.
[0041] When preparing for the horizontal retraction phase, the two protrusions 8 abut against the vertical sidewalls of the two baffles 9. By activating the electric push rod 7, the sliding seat 2 is driven to retract horizontally on the slide groove 4, causing the laser welding head 3 to retract. This forces the two protrusions 8 to press against the two baffles 9 in the opposite direction and slide downwards along the vertical sidewalls of the two baffles 9. During the retraction process, the laser welding head 3 passively rotates, thereby welding the vertical weld seam inside the component. When the laser welding head 3 continues to rotate and is parallel and in contact with the processing table 1, the vertical weld seam welding is completed. At this time, the two protrusions 8 slide out from the second gap, and the laser welding head 3 returns to its initial state through the rebound of the first torsion spring 6.
[0042] The beneficial effects of this embodiment are as follows: by setting up a horizontal drive unit and cooperating with the triggering mechanism, the position of the laser welding head 3 can be adjusted. Since only the laser welding head 3 needs to enter, the other drive and transmission mechanisms can be located outside the narrow space, so that the laser welding head 3 can smoothly enter the narrow space inside the component and weld the L-shaped weld (horizontal weld and vertical weld) inside the component. This not only reduces the difficulty of welding inside the component, but also improves the overall welding strength of the component.
[0043] For further details, please refer to Figures 5-8 In the above embodiment, the two protrusions 8 slide downward on the vertical sidewalls of the two baffles 9, thereby driving the laser welding head 3 to rotate to complete the welding of the vertical weld. However, as the laser welding head 3 rotates continuously, the first torsion spring 6 is compressed, which increases the resistance of the two protrusions 8 sliding downward on the vertical sidewalls of the two baffles 9.
[0044] Based on this, in order to reduce the resistance to sliding, this embodiment provides a structure to reduce resistance. The laser welding head 3 includes a base 12 and a body. The body is the part used for welding. The base 12 has irregular grooves 10 on both sides. The irregular grooves 10 include a limiting section, a transition section, and a holding section from the end closer to the body to the end farther away from the body. The limiting section has the smallest width and is used to insert a pin on the first torsion spring 6 to limit the pin. The transition section is a section whose width gradually increases. One end of the transition section is connected to the limiting section, and the other end is connected to the holding section. The holding section has a constant width, and its width is the same as the maximum part of the transition section. A pin on the first torsion spring 6 is inserted into the limiting section. The irregular groove 10 has an elongated guide groove 11. The guide groove 11 extends from the transition section to the holding section and passes through the base 12. In this way, the rotating shaft 5 is slidably and rotatably connected to the inside of the guide groove 11.
[0045] In this embodiment, the processing table 1 is provided with an electromagnetic adsorption mechanism (not shown in the figure), the outer shell of the base 12 has a magnetic adsorption structure, and the electromagnetic adsorption mechanism is used to limit and fix the laser welding head 3.
[0046] In this embodiment, the rotating shaft 5 has two states:
[0047] When the rotating shaft 5 is in the first state, the rotating shaft 5 is located at one end of the gradient section within the guide groove 11, and one pin of the first torsion spring 6 on the rotating shaft 5 is inserted into the limiting section. Through the compression force of the first torsion spring 6 itself (compression state), the laser welding head 3 is in an inclined state, that is, the tilting and deflection of the laser welding head 3 exerts a squeezing force on the first torsion spring 6. At this time, as... Figure 8 As shown, this facilitates the welding of horizontal welds inside the two components;
[0048] When the rotating shaft 5 is in the second state, the end of the rotating shaft 5 located within the guide groove 11 and within the holding section, that is, at this time, one pin of the first torsion spring 6 on the rotating shaft 5 is located within the holding section and is not limited by the limiting section. Figure 9 As shown.
[0049] Specifically, during the aforementioned horizontal forward section, the rotating shaft 5 is in the first state, and at this time, the rotating shaft 5 abuts against the inner wall of the front section of the guide groove 11. The forward state can also keep the rotating shaft 5 in the first state. The switch from the first state to the second state corresponds to the switch from the horizontal forward section to the horizontal backward section. As mentioned above, when the laser welding head 3 is about to perform the horizontal backward stroke, that is, when the two protrusions 8 are exactly abutting against the vertical sidewalls of the two baffles 9, the starting of the electric push rod 7 causes the sliding seat 2 to slide backward on the processing table 1, so that the two protrusions 8 passively slide downward on the vertical sidewalls of the two baffles 9. As the sliding seat 2 moves backward, the rotating shaft 5 and the guide groove 11... The frictional resistance of groove 11 is small, which drives the rotating shaft 5 to slide along the guide groove 11, thereby switching from the first state to the second state. This process forces one pin of the first torsion spring 6, which was originally inserted in the limiting section (first state), to separate from the limiting section, so that the squeezing force of the first torsion spring 6 is released. This causes the first torsion spring 6 to rotate counterclockwise while one pin slides from the inner wall of the transition section to the inner wall of the holding section until the first torsion spring 6 is fully abutted against the corner of the holding section, which completes the switch to the second state. Then the electric push rod 7 pulls the sliding seat 2 to continue to move backward, and the rotating shaft 5 then pulls the base 12 to move backward, completing the above-mentioned horizontal backward stroke.
[0050] In the aforementioned embodiment, when the laser welding head 3 is preparing to perform the horizontal backward stroke, the two protrusions 8 abut against the vertical sidewalls of the two baffles 9. In this embodiment, the downward rotation of the laser welding head 3 further compresses the first torsion spring 6, thus increasing the resistance to the movement of the laser welding head 3. However, in this embodiment, the horizontal forward stroke of the laser welding head 3 is unaffected. Therefore, during the horizontal backward stroke, the electric push rod is activated, causing the sliding seat 2 to slide horizontally backward. Since the two protrusions 8 of the laser welding head 3 abut against the vertical sidewalls of the two baffles 9, the laser welding head 3 does not move backward with the sliding seat 2. Instead, the sliding seat 2 drives the rotating shaft 5 to slide backward within the guide groove 11, forcing one pin of the first torsion spring 6, which was originally inserted in the limiting section (first state), to separate from the limiting section. This releases the previous compressive force of the first torsion spring 6, unlocking the limiting of the first torsion spring 6 and restoring it from the compressed state to its original state. However, this also reduces the resistance of the two protrusions 8 sliding downwards on the vertical sidewalls of the two baffles 9, that is, switching to the second state, causing the first torsion spring 6 to rotate counterclockwise while one pin slides from the inner wall of the transition section to the inner wall of the holding section, until the first torsion spring 6 is fully abutted against the corner of the holding section. Subsequently, the resistance of the laser welding head 3 being pulled from the above-mentioned inclined state to a more horizontal state is also smaller. In this embodiment, by the continued retraction of the sliding seat 2, the two protrusions 8 slide out from the second gap, that is, the L-shaped weld is completed.
[0051] Finally, the electric push rod 7 is activated, causing the sliding seat 2 to retract horizontally to its limit position on the slide groove 4. At this point, the outer shell of the base 12 corresponds to the electromagnetic adsorption mechanism pre-set on the processing table 1. By activating the electromagnetic adsorption mechanism, the laser welding head 3 is adsorbed and fixed, restricting the synchronous movement of the laser welding head and the sliding seat 2. The electric push rod 7 is then activated to advance its forward stroke. The forward movement of the sliding seat 2 drives the rotating shaft 5 to passively slide forward within the guide groove 11, moving from one end in the holding section to the other end in the limiting section. During this process, one pin of the first torsion spring 6 slides along the inner wall of the holding and transition sections in the irregular groove 10 until it is forced into the limiting section for insertion. During this process, the first torsion spring 6 rotates clockwise, forcing it to compress. At this point, the position of the first torsion spring 6 is reset (initial state). Then, the electromagnetic adsorption mechanism is closed. The squeezing force of the first torsion spring 6 forces the laser welding head 3 back to its initial tilted state. The next cycle can then begin.
[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
