Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of thermally broken aluminum window and door processing, specifically to a precision positioning device for a thermally broken aluminum window and door glass gluing machine. Background Technology

[0002] In the production process of thermally broken aluminum windows and doors, adhesive application is a crucial step in ensuring the sealing performance between the glass and the window frame. The precision positioning device, as a core component of the glass adhesive application machine, is responsible for positioning, clamping, and adjusting the posture of the window and door frames. Its positioning accuracy and operational flexibility directly determine the accuracy of the adhesive application trajectory and production efficiency. As window and door processing moves towards automation and integration, the shortcomings of traditional positioning devices are becoming increasingly apparent: existing devices generally cannot quickly position and clamp windows and doors, and lack a 180° rotation function, resulting in adhesive application requiring multiple operations, severely restricting processing efficiency, and easily leading to adhesive application misalignment. Traditional positioning devices mostly use manually adjustable support platforms and lateral clamping structures. For different sizes of thermally broken aluminum windows and doors, the positions of the positioning blocks and clamping cylinders need to be adjusted one by one with a wrench. The calibration process is cumbersome and time-consuming, making it difficult to achieve rapid model changeover. When clamping, it only relies on force applied from one or both sides, which is not stable enough for the clamping of irregular window frames. The frame is prone to shifting during the glue application process, causing the glue line to deviate from the sealing groove. Therefore, the development of a precise positioning device that can quickly position and clamp, and can rotate 180° to facilitate one-time glue application, has become an urgent need to improve the efficiency and quality of glue application for thermally broken aluminum windows and doors. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a precise positioning device for a thermally broken aluminum window and door glass gluing machine, which solves the technical problems that existing devices in the prior art generally cannot quickly position and clamp windows and doors, and do not have a 180° rotation function.

[0004] According to one aspect, at least one embodiment of this disclosure provides a precise positioning device for a thermally broken aluminum window and door glass adhesive applicator, comprising: A base frame and a conveyor belt, wherein the conveyor belt is installed in the base frame; A lifting assembly is disposed between the base frame and the conveyor belt; A clamping and flipping assembly is disposed in the base frame; The clamping and flipping assembly includes a pair of crossbeams, each with a rotating seat on its outer surface. The pair of rotating seats are rotatably connected to both sides of the base frame. Both ends of the crossbeams have horizontally opened elongated holes, and inner sliding rods are installed in the elongated holes. Clamping frames are slidably connected to the inner sliding rods.

[0005] As a further technical solution, telescopic cylinders are horizontally installed at both ends of the side surface of the cross frame, and the output end of the telescopic cylinder is connected to the clamping frame. An external gear is provided on the surface of the rotating seat on one side.

[0006] As a further technical solution, an outer frame is provided on one side of the base frame, and a rotating shaft is rotatably connected inside the outer frame. A drive gear is provided on the rotating shaft, and the drive gear meshes with the outer gear. A worm gear is provided at one end of the rotating shaft.

[0007] As a further technical solution, the outer frame side surface is provided with a worm gear that is driven to rotate by electricity, the worm gear and the worm wheel are connected by a threaded connection, and the rotating seat side surface is provided with a second cylinder.

[0008] As a further technical solution, the output end of the second cylinder passes through the crossbeam and is connected to a push plate. The surface of the push plate is provided with several stabilizing rods, and the stabilizing rods are connected to the crossbeam in a movable assembly.

[0009] According to another aspect, in at least one embodiment of the present invention, the lifting assembly includes a drive screw, which is electrically driven to rotate horizontally within the base frame, and both ends of the bottom surface of the base frame are horizontally slidably connected to movable seats.

[0011] As a further technical solution, a number of rolling rods are rotatably connected inside the conveyor belt, and the rolling rods are supported at the top inside the conveyor belt.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the clamping and flipping assembly solves the problems of slow positioning and inability to apply adhesive to both sides in traditional devices through multi-directional positioning and precise flipping design.

[0021] like Figures 1-3 As shown, it illustrates a precise positioning device for a thermally broken aluminum window and door glass adhesive applicator according to an embodiment of the present disclosure, comprising: A base frame 1 and a conveyor belt 2, wherein the conveyor belt 2 is installed in the base frame 1; Lifting assembly 4, which is disposed between the base frame 1 and the conveyor belt 2; Clamping and flipping assembly 3 is disposed in the base frame 1; The clamping and flipping assembly 3 includes a pair of horizontal frames 3-1, each with a rotating seat 3-2 on its outer surface. The rotating seats 3-2 are rotatably fitted onto both sides of the base frame 1. Each horizontal frame 3-1 has horizontally protruding elongated holes 3-3 at both ends, with an inner sliding rod 3-4 inside each hole. A clamping frame 3-5 is slidably fitted onto the inner sliding rod 3-4. Telescopic cylinders 3-6 are horizontally mounted at both ends of the side surface of the horizontal frame 3-1, with their output ends connected to the clamping frame 3-5. One side of the rotating seat 3-2 has an external gear 3-7 on its surface. An outer frame 3-8 is provided on one side of the base frame 1, with a rotating connecting rod inside the outer frame 3-8. A rotating shaft 3-9 is connected to the outer frame 3-8, and a drive gear 3-10 is mounted on the rotating shaft 3-9. The drive gear 3-10 meshes with the external gear 3-7. A worm gear 3-11 is mounted on one end of the rotating shaft 3-9. A worm 3-12, which is driven to rotate by electricity, is mounted on the side surface of the outer frame 3-8. The worm 3-12 is connected to the worm gear 3-11 by a threaded connection. A second cylinder 3-13 is mounted on the side surface of the rotating seat 3-2. The output end of the second cylinder 3-13 passes through the cross frame 3-1 and is connected to a push plate 3-14. Several stabilizing rods 3-15 are mounted on the surface of the push plate 3-14. The stabilizing rods 3-15 are movably connected to the cross frame 3-1.

[0022] In some examples, in order to achieve stable positioning and flipping of thermally broken aluminum windows and doors, and to avoid irregular glue lines caused by displacement or flipping angle deviation of the windows and doors during the glue application process, a clamping and flipping assembly 3 is designed. This assembly includes rotating seats 3-2 with inner rotating sets on both sides of the base frame 1 to provide rotational support for the cross frame 3-1. The inner slide rods 3-4 in the long holes 3-3 at both ends of the surface of the cross frame 3-1 guide the clamping frame 3-5 to slide horizontally. Together with the telescopic cylinders 3-6 on the side surface of the cross frame 3-1, a transverse clamping structure is formed. The telescopic cylinders 3-6 push the clamping frame 3-5 to move along the inner slide rods 3-4, applying clamping force from both sides of the window and door. The length of the long holes 3-3 is adapted to the clamping requirements of windows and doors of different widths.

[0023] The second cylinder 3-13 on the side surface of the rotating seat 3-2 drives the push plate 3-14 to move closer to the door and window surface. The stabilizing rod 3-15 on the surface of the push plate 3-14 is movablely fitted with the crossbar 3-1 to enhance the stability of the push plate 3-14 movement. It forms an auxiliary clamping on the door and window from the direction perpendicular to the clamping frame 3-5. It works with the clamping frames 3-5 on both sides to achieve multi-directional fixation and avoid deformation caused by uneven force on the corners of the door and window. It is especially suitable for precise positioning of the four corners.

[0024] The worm gear 3-12 inside the outer frame 3-8 is connected to the worm wheel 3-11 on the rotating shaft 3-9 by a threaded connection. The drive gear 3-10 meshes with the external gear 3-7 on the surface of the rotating seat 3-2 to form a reduction transmission structure. The worm gear 3-12 is electrically driven to rotate. After being reduced in speed by the worm wheel 3-11, the worm gear 3-12 drives the rotating shaft 3-9 and the drive gear 3-10 to rotate. In turn, the external gear 3-7 drives the rotating seat 3-2 and the crossbeam 3-1 to flip, so as to realize the smooth flipping of the door and window, ensure that the flipping angle is precise and controllable, and meet the position alignment requirements of double-sided adhesive application.

[0025] The multi-directional clamping structure is compatible with doors and windows of different specifications. The self-locking characteristic of the worm gear 3-11 and worm 3-12 transmission can prevent the angle from shifting due to external force during the flipping process, ensuring the stability of the position when applying glue.

[0026] During operation, the telescopic cylinder 3-6 and the second cylinder 3-13 work together to clamp the door and window, while the worm gear 3-11 and worm 3-12 drive the rotation to complete the double-sided adhesive application. Multi-directional clamping ensures accurate positioning, and the worm gear 3-11 and worm 3-12 transmission achieves stable rotation. All components work together to meet the positioning requirements for adhesive application.

[0027] like Figures 1-3 As shown in the figure, the lifting assembly 4 in this embodiment includes a drive screw 4-1, which is electrically driven to rotate horizontally within the base frame 1. Both ends of the bottom surface of the base frame 1 are horizontally slidably connected to movable seats 4-2. Both ends of the bottom of the conveyor belt 2 are provided with connecting frames 4-3. The connecting frames 4-3 and the movable seats 4-2 corresponding to the positions are rotatably connected to a pair of support rods 4-4 through pins.

[0028] In some examples, to achieve smooth height adjustment of the conveyor belt 2 and adapt to the door and window flipping operation of the clamping and flipping assembly 3, and to avoid interference with the conveyor belt 2 or positioning deviation caused by insufficient support when the door and window flips, a lifting assembly 4 is designed. This assembly includes a drive screw 4-1 that rotates horizontally inside the base frame 1 to provide power to the moving seat 4-2. When the drive screw 4-1 rotates, it drives the two moving seats 4-2 at both ends to slide horizontally towards or away from each other along the bottom surface of the base frame 1. The moving seat 4-2 and the bottom connecting frame 4-3 of the conveyor belt 2 are connected by a pair of support rods 4-4 that rotate through a pin shaft, forming a scissor lifting structure. When the moving seat 4-2 moves relative to each other, the support rods 4-4 rotate around the pin shaft to change the tilt angle, pushing the connecting frame 4-3 to drive the conveyor belt 2 to rise and fall vertically, thereby realizing continuous height adjustment of the conveyor belt 2.

[0029] The symmetrical layout of the scissor lift structure keeps the conveyor belt 2 horizontal during lifting, avoiding tilting that could cause the doors and windows to shift. The threaded drive of the drive screw 4-1 has the characteristics of high precision and good self-locking, which can accurately control the displacement of the moving seat 4-2, thereby achieving precise adjustment of the height of the conveyor belt 2 and ensuring that it matches the action rhythm of the clamping and flipping assembly 3. When the doors and windows need to be flipped, the conveyor belt 2 descends to avoid them, and rises to receive them after the flipping is completed, forming a seamless connection.

[0030] The connecting frame 4-3 provides a stable connection point between the support rod 4-4 and the conveyor belt 2. The sliding guide structure on the inner bottom surface of the base frame 1 ensures that the moving seat 4-2 moves smoothly and avoids jamming that affects the lifting accuracy.

[0031] During operation, conveyor belt 2 transports the doors and windows to the clamping position. Then, the drive screw 4-1 moves the movable seat 4-2, and the support rod 4-4 pushes the conveyor belt 2 up and down. In conjunction with the door and window flipping action, the material is then conveyed back after the glue is applied. The screw drive ensures precise lifting, the scissor structure provides stable support, and all components work together to adjust the height of conveyor belt 2 to meet the adaptation requirements of the flipping operation.

[0032] For example, such as Figure 1 As shown, a plurality of rolling rods 5 are rotatably connected inside the conveyor belt 2, and the rolling rods 5 are supported at the top inside the conveyor belt 2.

[0033] In some examples, several rotatable rollers 5 connected inside the conveyor belt 2 can provide uniform support to the top of the conveyor belt 2, preventing the conveyor belt 2 from sagging and deforming due to the weight of the doors and windows. The rollers 5 rotate synchronously with the conveyor belt 2, which can convert the sliding friction between the conveyor belt 2 and the doors and windows into rolling friction, reducing conveying resistance and making the doors and windows more stable during the conveying process, reducing positional deviation.

[0034] In actual use: The thermally broken aluminum doors and windows are conveyed to the positioning area via conveyor belt 2, with rolling rod 5 providing auxiliary support to ensure smooth conveying. The clamping and tilting assembly 3 is activated, and the telescopic cylinder 3-6 on the side surface of the crossbeam 3-1 pushes the clamping frame 3-5 to slide along the inner slide rod 3-4, clamping and positioning the doors and windows from both sides; the second cylinder 3-13 on the side of the rotating seat 3-2 drives the push plate 3-14 to fit against the doors and windows, and the stabilizing rod 3-15 provides auxiliary guidance to form multi-directional fixation. After one side is coated with adhesive, the drive screw 4-1 of the lifting assembly 4 drives the moving seat 4-2 to slide, and the support rod 4-4 pushes the conveyor belt 2 down to avoid obstruction. The electric drive worm gear 3-12 rotates, and after being reduced in speed by the worm wheel 3-11, the drive gear 3-10 meshes with the external gear 3-7, causing the rotating seat 3-2 to tilt, achieving a 180° rotation of the doors and windows. After flipping into place, conveyor belt 2 rises to receive the object and repeats the gluing process. After the gluing is completed, the clamping structure is released, and conveyor belt 2 sends the door and window out, achieving rapid positioning and double-sided gluing connection throughout the process.
