Description

Technical Field

[0001] This disclosure pertains to the field of aluminum door and window manufacturing technology, and particularly relates to a positioning and adhesive application device and method for the mullion of aluminum doors and windows. Background Technology

[0002] The mullion machine is used for connecting cross mullions in aluminum doors and windows, as well as processing various types of holes, slots, and lock holes. It can complete the drilling and installation connection of cross mullions in one go. Existing mullion machines cannot fix the mullion during drilling and assembly of the frame and mullion, making it impossible to guarantee accurate positioning between the frame and mullion. Furthermore, when applying sealant to both ends of the mullion, since the aluminum door and window frame is already fixed, manual labor is required using pry bars or other tools to create a gap between the frame and mullion before applying sealant with a hand-held glue gun. Additionally, during mullion installation, because a baffle for fixing the window frame is set in the middle of the worktable, the window frame needs to be lifted when inserting or removing it. After installing one mullion, continuing to install another requires lifting and rotating the entire window frame; this can lead to installation position deviations, is time-consuming and labor-intensive, poses safety hazards, and ultimately leads to rework, reducing production efficiency. Summary of the Invention

[0003] In view of the defects or deficiencies in the prior art, this disclosure provides a positioning and glue application device and method for aluminum door and window mullions, which can fix the window frame and mullion, open the gap between the window frame and mullion, and realize automatic glue application, thereby improving the installation efficiency of mullion.

[0004] To achieve the above objectives, the present disclosure adopts the following technical solution:

[0005] In a first aspect, embodiments of this disclosure provide a positioning and glue-applying device for aluminum door and window mullions, including a base and a working platform. The working platform is fixed above the base by a support plate. A positioning mechanism and a frame support mechanism are provided between the base and the working platform. A pressing mechanism and an automatic glue-applying mechanism are provided above the working platform.

[0006] Furthermore, the supporting upright plate includes a left upright plate, a right upright plate, a first side upright plate, a second side upright plate, and a middle upright plate, wherein the left upright plate and the right upright plate are respectively arranged on the left and right sides of the base plate, the first side upright plate and the second side upright plate are arranged side by side on the rear side of the base plate, and the middle upright plate is arranged on the front side of the base plate.

[0007] Furthermore, the positioning mechanism includes a rear mullion limiting component and a front mullion limiting component. The rear mullion limiting component is fixed on the left upright plate, and the front mullion limiting component is fixed on the bottom surface of the work platform.

[0008] Furthermore, the support frame mechanism includes a fixed base and a third slider guide rail. The guide rail on the third slider guide rail is fixed to the side wall of the central plate, and the fixed base is fixed to the slider of the third slider guide rail.

[0009] Furthermore, a second support is provided on the side wall of the neutral plate. The second support is located below the third slider guide rail. A push rod lifting cylinder is connected between the fixed seat and the second support. An electric push rod is provided on the top of the fixed seat.

[0010] Furthermore, the clamping mechanism includes a first frame clamping component, a second frame clamping component, and a mullion clamping component, with the first frame clamping component and the second frame clamping component respectively disposed on both sides of the mullion clamping component.

[0011] Furthermore, the first frame clamping assembly and the mullion clamping assembly are fixed to the first side plate, and the second frame clamping assembly is fixed to the second side plate.

[0012] Furthermore, the automatic glue dispensing mechanism includes a screw and slider assembly, a vertical plate, a glue dispensing cylinder, and a connecting plate. The vertical plate is fixed on the slider of the screw and slider assembly. The connecting plate is set at the lower end of the side wall of the vertical plate through a fourth slider guide rail. One end of the glue dispensing cylinder is connected to the top of the vertical plate, and the other end is connected to the top of the connecting plate.

[0013] Furthermore, the connecting plate is provided with two connecting seats, which are arranged parallel to each other at the upper and lower ends of the side wall of the connecting plate. Multiple guide posts are provided between the two connecting seats, and compression springs are sleeved on the outer side of the multiple guide posts. A clamping seat is also provided between the two connecting seats. The clamping seat is slidably connected to the guide posts and is used to clamp the pneumatic glue gun.

[0014] Secondly, this disclosure also provides a method for positioning and applying sealant to mullions in aluminum doors and windows, utilizing the positioning and sealant application device for mullions in aluminum doors and windows as described above, including the following steps:

[0015] First, place the two positioning glue-applying devices on both sides of the conveyor platform, push the window frame to the designated position on the work platform through the conveyor platform, raise the front limit plate on the mullion front limit assembly, and then place the mullion into the window frame with one side close to the front limit plate.

[0016] Adjust the position of the two positioning glue-applying devices so that the two side frames are close to the limiting blocks of the frame clamping assembly. Then use the frame clamping assembly to clamp the frame. At this time, the rear limiting plate on the mullion rear limiting assembly clamps the other side of the mullion. At the same time, use the mullion clamping assembly to clamp and fix the mullion to prevent the window frame and mullion from moving.

[0017] Then, the electric push rod on the frame support mechanism is used to create a gap between the frame and the mullion.

Detailed Implementation

[0027] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0028] Terminology Explanation: The terms “installation,” “connection,” “linking,” and “fixing” in this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to an internal connection between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0029] Example 1

[0030] One typical implementation of this disclosure is as follows: Figure 1 As shown, it includes a base 1 and a working platform 2. The working platform 2 is fixed above the base 1 by a support plate. A positioning mechanism and a support frame mechanism 3 are provided between the base 1 and the working platform 2. A pressing mechanism and an automatic glue dispensing mechanism 4 are provided above the working platform 2.

[0031] The supporting uprights include a left upright 11, a right upright 12, a first side upright 13, a second side upright 14, and a middle upright 15. The left and right uprights 11 and 12 are respectively positioned on the left and right sides of the base plate 1, the first and second side uprights 13 and 14 are arranged side-by-side on the rear side of the base plate 1, and the middle upright 15 is positioned on the front side of the base plate 1. By providing uprights to support the working platform 2 in four directions on the base plate 1, the stability of the working platform 2 is ensured.

[0032] The positioning mechanism includes a rear mullion limiting component 5 and a front mullion limiting component 6. The rear mullion limiting component 5 is mounted on the base 1 via the left upright plate 11, and the front mullion limiting component 6 is mounted on the bottom surface of the working platform 2.

[0033] Specifically, such as Figure 2 As shown, the rear limiting assembly 5 of the mullion includes a fixed support plate 51, a second slider guide rail 52, a rear limiting lifting cylinder 53, a first support 54, a rear limiting plate 55, and a rear limiting clamping cylinder 56. The fixed support plate 51 has an "L"-shaped structure, and one side of it is fixed to the slider of the second slider guide rail 52 by screws. The guide rail of the second slider guide rail 52 is fixed to the side wall of the left vertical plate 11. One end of the rear limiting lifting cylinder 53 is fixed to the left vertical plate by the first support 54. On the side wall of 11, the other end is connected to the fixed support plate 51 by screws. The rear limiting clamping cylinder 56 is installed on the upper surface of the fixed support plate 51. The rear limiting plate 55 is fixed on the telescopic shaft of the rear limiting clamping cylinder 56. The working platform 2 has a middle mullion rear limiting hole. The top of the rear limiting plate 55 passes through the middle mullion rear limiting hole from the bottom surface of the working platform 2, so that the top of the rear limiting plate 55 is above the working platform 2, thereby limiting the middle mullion placed on the working platform 2. During operation, the rear limiting lifting cylinder 53 drives the fixed support plate 51 fixed on the second slider guide rail 52 to move upward, and the rear limiting clamping cylinder 56 drives the rear limiting plate 55 to move forward to clamp the middle mullion.

[0034] The aforementioned mullion front limiting assembly 6 includes a front limiting plate 61, a fixed bracket 62, a first slider guide rail 63, and a front limiting cylinder 64.

One end of the front limiting cylinder 64 is fixed to the bottom surface of the fixed bracket 62, and the other end is fixedly connected to the front limiting plate 61 by screws. The working platform 2 has a mullion front limiting hole. The top end of the front limiting plate 61 passes through the mullion front limiting hole from the bottom surface of the working platform 2, so that the top end of the front limiting plate 61 can be positioned above the working platform 2, thereby limiting the mullion placed on the working platform 2. During operation, the front limiting cylinder 64 drives the front limiting plate 61 to lift upward.

[0035] By setting the rear limiting component 5 and the front limiting component 6 of the mullion, the mullion can be fixed in a suitable position on the window frame, which facilitates the installation of the mullion.

[0036] The support frame mechanism 3 is mounted on the base 1 via the central plate 15, such as Figure 3 As shown, the frame-supporting mechanism 3 includes a fixed base 31, an electric push rod 32, a third slider guide rail 33, a push rod lifting cylinder 34, and a second support 35. The fixed base 31 is fixed to the slider of the third slider guide rail 33 by screws. The guide rail of the third slider guide rail 33 is fixed to the side wall of the central plate 15. One end of the push rod lifting cylinder 34 is fixed to the side wall of the central plate 15 through the second support 35, and the other end of the push rod lifting cylinder 34 is connected to the fixed base 31 by screws. The electric push rod 32 is fixed to the fixed base 31. The working platform 2 has a frame-supporting hole. The electric push rod 32 passes through the frame-supporting hole from the bottom surface of the working platform 2, so that the electric push rod 32 is located above the working platform 2, thereby enabling the window frame placed on the working platform 2 to be opened. During operation, the push rod lifting cylinder 34 drives the fixed base 31 fixed to the third slider guide rail 33 to move upward, and the electric push rod 32 moves forward to support the window frame.

[0037] By setting the support frame mechanism 3, a gap can be created between the mullion and the window frame, which facilitates the subsequent caulking work.

[0038] like Figure 1 As shown, the clamping mechanism includes a first frame clamping component 7, a second frame clamping component 8, and a mullion clamping component 9. The first frame clamping component 7 and the second frame clamping component 8 are respectively disposed on both sides of the mullion clamping component 9. The first frame clamping component 7 and the mullion clamping component 9 are fixed on the first side plate 13, and the second frame clamping component 8 is fixed on the second side plate 14.

[0039] The first frame clamping component 7 and the second frame clamping component 8 have the same structure, such as Figure 2 As shown, the first frame clamping assembly 7 includes a support plate 71, a limiting block 72, a frame clamping cylinder 73, and a frame clamping plate 74. The frame clamping cylinder 73 is fixed to the first side upright plate 13 via the support plate 71. The limiting block 72 is fixed to the support plate 22 and located below the frame clamping cylinder 73. The frame clamping plate 74 is fixed to the telescopic shaft of the frame clamping cylinder 73. During operation, the frame clamping cylinder 73 drives the frame clamping plate 74 to clamp the frame.

[0040] like Figure 2 and Figure 3As shown, the mullion clamping assembly 9 includes a mullion clamping cylinder 91, a fixed support 92, a fixed plate 93, and a mullion clamping plate 94. The mullion clamping cylinder 91 is mounted on the fixed support 92 via the fixed plate 93. The fixed support 92 is fixed to the first side upright plate 13. The mullion clamping plate 94 is fixed to the telescopic shaft of the mullion clamping cylinder 91. During operation, the mullion clamping cylinder 91 drives the mullion clamping plate 94 to clamp the mullion.

[0041] By setting the first frame clamping component 7, the second frame clamping component 8, and the mullion clamping component 9, the window frame and the mullion are clamped and fixed during the installation of the mullion, so as to prevent the window frame and the mullion from moving and affecting the installation effect.

[0042] The automatic glue dispensing mechanism 4 is fixed on the fixed support 92 of the mullion clamping assembly 9, such as Figure 4 As shown, the automatic glue dispensing mechanism includes a stepper motor 401, a lead screw and slider assembly 402, a vertical plate 403, a glue dispensing cylinder 404, a pneumatic glue gun 405, a connecting plate 406, and a clamping seat 407. The lead screw and slider assembly 402 is mounted on a fixed plate 408, and the stepper motor 401 is mounted on a support plate 409, driving the lead screw and slider assembly 402 to move via a coupling. The fixed plate 408 is mounted on a fixed support 92. The vertical plate 403 is fixed to the slider of the lead screw and slider assembly 402. One end of the glue dispensing cylinder 404 is connected to the top of the vertical plate 402 via a support column 410, and the other end is fixed to the top of the connecting plate 406 via screws. The connecting plate 406 is fixed to a fourth slider guide rail 411, which is fixed to the lower end of the side wall of the vertical plate 402. The connecting plate 406 is provided with a connecting seat 407. 12. Guide post 413 and compression spring 414. Two connecting seats 412 are provided, and the two connecting seats are arranged parallel to each other on the upper and lower ends of the side wall of the connecting plate 406. Two guide posts 413 are provided, symmetrically arranged between the two connecting seats 406. The two ends of the guide post 413 are fixedly connected to the two connecting seats 406 respectively. A clamping seat 407 is provided on the guide post 413. The clamping seat 407 is used to fix the pneumatic glue gun 405. The clamping seat 407 is slidably connected to the guide post 413. The clamping seat 407 can slide along the length direction of the guide post 413, so that the clamping seat 407 can reciprocate between the two connecting seats 412.

[0043] A compression spring 414 is sleeved on the outside of the guide post 413. The compression spring 414 is located between the bottom surface of the upper connecting seat 412 on the connecting plate and the upper surface of the clamping seat 407. The compression spring 414 plays a buffering role on the movement of the clamping seat 407.

[0044] During operation, the glue-applying cylinder 404 first drives the pneumatic glue gun 405 to push against the gap between the frame and the middle mullion. Since there is a guide post 413 and a compression spring 414 sleeved on the guide post 413 between the clamping seat 407 and the connecting seat 412, it can buffer the pneumatic glue gun 405 when the nozzle of the pneumatic glue gun 405 touches the workpiece, thus protecting the pneumatic glue gun 405. Then, the stepper motor 401 drives the lead screw slider assembly 402 to move through the coupling, and the pneumatic glue gun 405 completes the automatic glue application.

[0045] Example 2

[0046] This embodiment provides a method for positioning and applying adhesive to the mullions of aluminum doors and windows, utilizing a positioning and applying adhesive device for the mullions of aluminum doors and windows as described in Embodiment 1, and includes the following steps:

Figure 5 As shown, the front limiting plate on the mullion front limiting assembly rises, and then the mullion is placed inside the window frame with one side close to the front limiting plate;

[0048] Adjust the position of the two positioning glue-applying devices so that the two side frames are close to the limiting blocks of the frame clamping assembly. Then use the frame clamping assembly to clamp the frame. At this time, the rear limiting plate on the mullion rear limiting assembly clamps the other side of the mullion. At the same time, use the mullion clamping assembly to clamp and fix the mullion to prevent the window frame and mullion from moving.

[0049] Then, the electric push rod on the frame support mechanism is used to create a gap between the frame and the mullion. The automatic glue application mechanism moves the pneumatic glue gun to the gap and applies glue to it. After the glue application is completed, the electric push rod on the frame support mechanism retracts, all cylinders return to their original positions, and the lead screw and slider assembly returns to its initial position, completing the installation of the aluminum door and window mullion.
