Description

Aluminum alloy frame glue injection device Technical Field

[0001] This invention relates to the field of aluminum alloy door and window processing technology, and specifically discloses an adhesive injection device for processing aluminum alloy door and window frames. Background Technology

[0002] During the manufacturing process of aluminum alloy doors and windows, aluminum alloy profiles are typically cut and then assembled into a rectangular aluminum alloy frame structure using pins. To improve the stability of the frame structure and the sealing of the profile joints, adhesive is often applied to the four right-angle joints of the frame.

[0003] The current process for applying adhesive to aluminum alloy frames still relies on manual application. An operator holds a glue applicator and inserts it into the glue injection hole on the side of the frame. Pressure is then applied to force the adhesive through the injection hole into the cavity at the joint of the profile. The adhesive is applied until it overflows from the outlet hole on the other side, indicating that the joint is now fully coated. This traditional manual application process is not only labor-intensive and inefficient, but also fails to completely fill the joint, especially during downward application where gravity causes the adhesive to flow out of the outlet hole. This lack of full coverage results in gaps at the joint, leading to poor sealing and waterproofing of the aluminum alloy frame. To address these shortcomings of the current manual application method, this application proposes an aluminum alloy frame adhesive application device that effectively solves the aforementioned technical problems. Summary of the Invention

[0004] The present invention aims to provide an adhesive injection device for processing aluminum alloy door and window frames, so as to solve the problems of high labor intensity, low work efficiency and poor sealing and waterproofing when manually injecting adhesive into aluminum alloy door and window frames.

[0005] This invention is achieved through the following technical solution:

[0006] An aluminum alloy frame glue injection device includes a frame positioning unit and a controller. The frame positioning unit is provided with a transmission mechanism. The transmission mechanism includes a transmission seat that passes through the lower end of the frame positioning unit. Movable frames are provided at both the left and right ends of the transmission seat. The transmission seat is provided with a transmission component that enables the two movable frames to move closer or further apart. A vertical plate is provided at the upper end of the movable frame. Each vertical plate has a glue injection mechanism at both the front and rear ends that is aligned with the glue injection holes at the front and rear ends of the frame.

[0007] Both ends of the longitudinal plate are provided with glue injection amount sensing components. The glue injection amount sensing components include a block. A guide cylinder and a pressure sensor are provided on the side of the block facing the frame positioning unit. The pressure sensor is connected to a moving block located in the guide cylinder by a spring. A sensing rod extending out of the guide cylinder is connected to the moving block. A plunger is provided at the outer end of the sensing rod, which is aligned with and adapted to the glue outlet holes on the left and right sides of the frame.

[0008] As a further provision of the above solution, the frame positioning unit includes a base and a frame. The upper surface of the base is provided with a tray for placing the aluminum alloy frame. The upper end of the frame is provided with a first telescopic member, and the lower end of the first telescopic member is connected to a pressure plate aligned with the tray.

[0009] As a further provision of the above scheme, the transmission assembly includes a bidirectional lead screw and a guide member arranged in parallel in the transmission seat, and one end of the bidirectional lead screw is connected to a lead screw motor. The lower end of the moving frame matches the guide member and is provided with a threaded hole or lead screw nut that matches the bidirectional lead screw.

[0010] As a further provision of the above scheme, end plates are provided at both the front and rear ends of the longitudinal plate, and the glue injection mechanism includes a bracket provided on the end plate. A second telescopic member is provided at the end of the bracket. A glue tube fixing member is connected to the end of the second telescopic member along the slide rail on the bracket. A glue tube is provided on the glue tube fixing member. A glue injection nozzle is provided at the end of the glue tube facing the frame positioning unit. A glue extrusion drive member for realizing glue extrusion is provided on the glue tube fixing member away from the glue injection nozzle.

[0011] As a further provision of the above solution, the extrusion drive includes a screw jack, the end of which extends into the glue cylinder is connected to an extrusion plate, and the drive motor and pressure sensor in the screw jack are both electrically connected to the controller.

[0012] As a further feature of the above scheme, the longitudinal plate includes a left arm segment and a right arm segment, and the ends of the left arm segment and the right arm segment are connected to L-shaped movable plates. A transmission box is provided on the outside of the two L-shaped movable plates, and a gear transmission assembly is provided on the transmission box to realize the left arm segment and the right arm segment moving towards each other or away from each other.

[0013] As a further provision of the above scheme, the two L-shaped movable plates are arranged in parallel in the transmission box, and toothed surfaces are provided on the opposite sides of the two L-shaped movable plates. A gear motor is provided on the transmission box, and a power gear that meshes with the two toothed surfaces is provided on the motor shaft of the gear motor.

[0014] As a further feature of the above scheme, both the left and right arm segments are provided with movable grooves, the block is movably disposed in the movable grooves, and the guide cylinder is disposed toward the support plate through the corresponding strip opening of the movable groove. The end of the movable groove is threadedly connected to a first adjusting screw that acts on the block.

[0015] As a further feature of the above scheme, the other ends of both the left and right arm segments are threadedly connected to a second adjusting screw for adjusting the position of the glue injection mechanism.

[0016] The glue injection device disclosed in this invention, when performing glue injection on aluminum alloy door and window frames, clamps and fixes the aluminum alloy door and window frames by the frame positioning unit, and aligns the glue outlet holes on the left and right sides of the fixed frame with the glue injection amount sensing component.

[0017] Next, the transmission assembly is activated to bring the two moving frames closer together until the plunger in the glue injection quantity sensing assembly is inserted into the glue outlet hole on the side of the frame and blocks it. Then, the glue injection mechanism is activated, and the second cylinder in the glue injection mechanism pushes the glue injection nozzle toward the glue injection hole at the end of the frame. Then, the glue extrusion drive is activated to push the base inside the glue cylinder to realize the glue extrusion process.

[0018] As the extrusion process proceeds, the adhesive is discharged from the nozzle and enters the inner cavity of the frame profile joint through the injection hole, filling the cavity completely. Because the outlet hole is sealed by the plunger, the continuous extrusion forces the adhesive to flow into the gaps at the profile joint, thus completely sealing the gaps. Finally, as the extrusion process continues, the increased pressure of the adhesive in the inner cavity forces the plunger to move outward. Feedback from the pressure sensor then triggers a stop signal from the controller, halting the extrusion drive. The system resets after the adhesive injection is complete.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The adhesive injection device disclosed in this invention can simultaneously inject adhesive at the four right-angle joints of aluminum alloy door and window frames, realizing the automation of the adhesive injection process for aluminum alloy frames. This not only reduces the labor intensity of operators but also greatly improves the efficiency of adhesive injection.

[0021] The glue injection device disclosed in this invention, through the design of the glue injection volume sensing component, can block the glue outlet on the frame during the glue injection process. This ensures that the injected glue only moves outward by fully filling the inner cavity and gaps at the profile connection. Then, the spring transmits the force to the pressure sensor, which promptly feeds back to the controller. The controller then promptly shuts off the glue injection action. The entire glue injection process not only ensures that the frame profile connection is fully glued, guaranteeing the connection stability and sealing of the entire frame, but also avoids excessive glue waste, resulting in excellent glue injection effect for aluminum alloy door and window frames.

[0022] The glue injection device disclosed in this invention further improves the design so that when used for glue injection treatment of aluminum alloy door and window frames of different sizes and models, the distance between the front and rear glue injection mechanisms can be initially adjusted first, and then the position of the glue injection volume sensing component and the glue injection mechanism can be precisely adjusted by adjusting the screw. This allows the adjusted glue injection mechanism and glue injection volume sensing component to be precisely aligned with the glue injection hole and glue outlet hole on the frame, making the entire glue injection device effectively applicable to glue injection treatment of various types of aluminum alloy door and window frames, and having better applicability.

[0032] 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 only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to Figures 1-8 and the embodiments. Embodiment 1

[0034] Example 1 discloses a glue-applying device for processing aluminum alloy door and window frames. Referring to Figures 1 and 2, the main body of the glue-applying device includes a frame positioning unit 100, an automatic glue-applying unit, and a controller 200. Specifically, the frame positioning unit 100 includes a base 101, on the upper surface of which a support plate 102 for placing the aluminum alloy frame is fixed. A bracket 103 is fixed to the rear side of the base 101, with its upper end extending directly above the support plate 102. A first cylinder 104 is then mounted on the top of the bracket 103, and a pressure plate 105, aligned vertically with the support plate 102, is connected to the lower end of the first cylinder 104. In a specific design, the support plate 102 and the pressure plate 105 can be arranged in a cross shape, and the first cylinder 104 can be replaced by other telescopic components.

[0035] Referring to Figures 1, 3, and 4, the automatic glue dispensing unit includes a transmission mechanism 300, a glue dispensing mechanism 400, and a glue dispensing volume sensing component 500. Specifically, the transmission mechanism 300 includes a transmission base 301 extending through the lower end of the housing 101. A bidirectional lead screw 302 and a guide member 303 are disposed within the transmission base 301, arranged parallel to each other. A first motor 304 is connected to the end of the bidirectional lead screw 302. Two movable frames 305 are symmetrically arranged on the transmission base 301, with the lower ends of the movable frames 305 matching the guide members 303. A threaded hole matching the bidirectional lead screw 302 or a corresponding lead screw nut is provided at the lower end of the movable frames 305. The transmission mechanism 300 uses the first motor 304 as a power source, and through the action of the bidirectional lead screw and the guide member, the two movable frames 305 can move towards or away from each other.

[0036] Additionally, a longitudinal plate 306 is connected to the upper end of the movable frame 305. The longitudinal plate 306 is flush with the upper surface of the support plate 102, and end plates 307 are provided at both ends of the longitudinal plate 306. A glue dispensing mechanism 400 is provided on each end plate 307, and a glue dispensing amount sensing component 500 is provided at each end of the longitudinal plate 306. Each glue dispensing amount sensing component 500 corresponds to the same group of glue dispensing mechanisms 400, and both the glue dispensing mechanisms 400 and the glue dispensing amount sensing components 500 are electrically connected to the controller 200.

[0037] Referring to Figure 5, the glue injection mechanism 400 includes a bracket 401 connected to an end plate, and a second cylinder 402 fixed to the end of the bracket 401. A slide rail 403 parallel to the longitudinal plate 306 is provided on the bracket 401. A glue cartridge fixing member 404 connected to the piston rod of the second cylinder 402 is slidably mounted on the slide rail 403, allowing the glue cartridge fixing member 404 to move along the slide rail 403 under the pushing action of the second cylinder 402. A glue cartridge 405 is detachably mounted on the glue cartridge fixing member 404. A glue injection nozzle 406 is provided at the end of the glue cartridge 405 away from the second cylinder 402, and the glue injection nozzle 406 is aligned with the glue injection hole on the aluminum alloy frame. A screw jack 407 is provided on the glue cartridge fixing member 404 near the end of the second cylinder 402, and an extrusion plate (not shown in the figure) extending to the opening end of the glue cartridge 405 is connected to the end of the screw jack 407. The screw jack 407 pushes the base inside the glue cylinder 405, thereby realizing the glue extrusion process. The drive motor on the screw jack 407 is electrically connected to the controller 200, and can be stopped promptly by a control signal issued by the controller 200. Alternatively, the screw jack 407 in this embodiment can be replaced by other telescopic drive components with timely stopping capabilities.

[0038] Referring to Figure 6, the dispensing volume sensing assembly 500 includes a body 501. A guide cylinder 502 and a pressure sensor 503 are disposed at the end of the body 501 facing the tray 102. The pressure sensor 503 is disposed at the inner end of the guide cylinder 502 and electrically connected to the controller 200. A moving block 504 is disposed within the guide cylinder 502, and a spring 505 connects the moving block 504 and the pressure sensor 503. A sensing rod 506 extending out of the guide cylinder 502 is connected to the moving block 504. A plunger 507, adapted to the dispensing hole on the frame, is disposed at the outer end of the sensing rod 506. To facilitate the insertion of the plunger 507 into the dispensing hole, the outer end of the plunger 507 is chamfered.

[0039] When the glue injection device disclosed in Embodiment 1 injects glue into the aluminum alloy door and window frame, the operator first places the frame on the support plate 102 according to the placement requirements, so that the glue injection amount sensing components 500 on both sides are aligned with the glue outlet holes on both sides of the frame. Then, under the action of the first cylinder 104, the pressure plate 105 is pushed down, thereby fixing the frame before glue injection.

[0040] Next, the operator presses the start button on the controller 200 to start the transmission mechanism 300. Then, under the action of the bidirectional lead screw 302 and the guide member 303, the two moving frames 305 move towards each other until the plunger 507 on the glue injection volume sensing component 500 is inserted into the glue outlet hole, at which point the operation stops. At this time, the glue injection nozzle 406 in the glue injection mechanism 400 is aligned with the glue injection hole on the aluminum alloy frame. Subsequently, the second cylinder 402 is activated to push the glue cylinder fixing member 404 towards the glue injection hole until the glue injection nozzle 406 is inserted into the glue injection hole. Then, the lead screw jack 407 is activated to push the base inside the glue cylinder 405, thereby realizing the glue extrusion process.

[0041] As the glue extrusion process of the glue cartridge 405 proceeds, the inner cavity of the profile at the edge connection is gradually filled with glue until it flows to the glue outlet. At this point, because the glue outlet is blocked by the plunger 507, the liquid in the inner cavity of the profile cannot be discharged through the glue outlet. As the glue extrusion process continues, the glue flows into the gap at the profile connection, thus completely sealing the gap. As the glue extrusion process continues, the increase in internal glue pressure will squeeze the plunger 507 outward, and the pressure will be fed back to the pressure sensor 503 by the action of the spring 505. Then, the pressure sensor 503 will feed back the signal to the controller 200, and the controller 200 will generate a stop signal to stop the operation of the screw jack 407. Finally, after the glue injection is completed, everything except the screw jack 407 can be reset. Example 2

[0042] Example 2 discloses an aluminum alloy frame glue injection device that is an improved design based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0043] Referring to Figures 4, 7, and 8, the longitudinal plate 306 in this embodiment 2 includes a left arm segment 3061 and a right arm segment 3062. L-shaped movable plates 308 are connected to the ends of the left arm segment 3061 and the right arm segment 3062 that are close to each other. The two L-shaped movable plates 308 are staggered and parallel, and toothed surfaces are provided on their opposite sides. A transmission box 309 is provided outside the two L-shaped movable plates 308, so that both L-shaped movable plates 308 extend into the transmission box 309. A gear motor 310 is then provided on the transmission box 309. A power gear 311 extending into the transmission box 309 is connected to the motor shaft of the gear motor 310, and the power gear 311 simultaneously meshes with the toothed surfaces on the two L-shaped movable plates 308. The left arm segment 3061 and the right arm segment 3062 can move closer to each other or further away from each other by controlling the forward and reverse rotation of the gear motor 310, thereby controlling the distance between the glue injection mechanisms 400 at both ends of the same longitudinal plate 306.

[0044] Movable grooves 312 are provided on both the left arm segment 3061 and the right arm segment 3062. The block 501 of the glue dispensing amount sensing assembly 500 is then placed in the movable groove 312, and the guide cylinder 502 is positioned towards the support plate 102 through the corresponding slot of the movable groove 312. A first adjusting screw 313 is then threaded to the end of the movable groove 312, and the end of the first adjusting screw 313 is connected to the block 501.

[0045] In addition, in this embodiment 2, an adjustment port for extending the glue injection nozzle 406 is provided on the end plate 307. Then, a second adjustment screw 314 is threadedly connected to the end of the longitudinal plate 306 on the opposite side of the adjustment port. At the same time, the bracket 401 is slidably positioned along the end plate 307, and the end of the second adjustment screw 314 is connected to the bracket 401, so that the distance between the two glue injection nozzles 406 on the same side can be accurately adjusted under the action of the second adjustment screw 314.

[0046] When the glue injection device disclosed in Embodiment 2 is used for glue injection processing of aluminum alloy frames of different sizes and models, the distance between the glue injection mechanisms 400 at both ends of the same vertical plate 306 is first controlled by controlling the forward and reverse rotation of the gear motor 310. Then, the position of the glue injection volume sensing component 500 is finely adjusted by the first adjusting screw 313 to align it with the glue outlet hole on the frame. At the same time, the glue injection nozzle 406 is finely adjusted to align with the glue injection hole on the frame by the second adjusting screw 314. This ensures that the device can be accurately positioned and without deviation during operation, so that the entire glue injection device can be applied to various aluminum alloy frames and has a wider range of applications.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
