Description

Technical Field

[0001] This invention relates to the field of door frame processing technology, specifically to a smart adhesive dispensing method and equipment for door frame strips. Background Technology

[0002] Door frame strip dispensing is a core process in door, window, and custom furniture manufacturing, and its precision directly determines the product's sealing performance, structural strength, and appearance quality. Early dispensing relied on manual hand-held application, resulting in significant quality fluctuations and low efficiency. Mid-stage methods employed fixed triaxial dispensing machines with specialized fixtures, improving consistency but struggling to adapt to the rapid positioning of door frame strips of varying lengths and widths, and failing to solve the problem of adapting equipment for both long and short strips. Existing technologies utilize sensor-driven intelligent adjustment solutions, such as visual recognition combined with servo fine-tuning, attempting to achieve adaptive dimensional control through real-time perception. However, the use of high-precision cameras, lasers, and closed-loop control systems leads to a surge in hardware costs, with sensor modules accounting for over 35% of the total cost, resulting in high equipment costs. Furthermore, relying on sensors for fine-tuning is generally slow, adding 8–15 seconds per piece and extending the dispensing cycle time by 30%–50%, severely hindering production line efficiency. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the present invention aims to provide a smart adhesive dispensing method and device for door frame strips, wherein the smart adhesive dispensing method for door frame strips includes the following steps: S1. Based on the length, width, and thickness of the door frame strip to be processed, set the dispensing parameters of the dispensing machine, including the dispensing distance and dispensing method; S2. Position the door frame strip to be processed and drive the dispensing machine to move to the initial position at one end of the door frame strip; S3. Drive the dispensing machine to move automatically to dispense adhesive; S4. Reset the dispensing machine, replace the sliding door frame strip, and repeat S2-S3 until all dispensing is completed.

[0004] To enable the output of a dispensing machine to automatically align with the center of door frame strips of different widths without adjustment, an intelligent dispensing device for door frame strips is also included. This device is applied to an intelligent dispensing method for door frame strips and includes a worktable, a dispensing assembly, and a drive assembly. A positioning stop and a top bonding strip are fixedly installed on the worktable. The top bonding strip is perpendicular to and bonded to one end of the positioning stop. A movable fixing strip, parallel to the positioning stop, is slidably installed on one side of the worktable. The movable fixing strip is equipped with a position locking structure. The movable fixing strip, in conjunction with the positioning stop and the top bonding strip, clamps and fixes the door frame strip. The drive assembly drives the dispensing assembly to move along the length direction of the positioning stop. The dispensing assembly includes a dispensing machine and an automatic positioning bracket. The dispensing machine is slidably installed at the center of the automatic positioning bracket. The automatic positioning bracket moves synchronously with the movable fixing strip and always ensures that the output of the dispensing machine is located on the perpendicular bisector of the minimum connecting line between the positioning stop and the movable fixing strip on opposite sides.

[0005] To achieve the goal of ensuring that the automatic positioning bracket moves synchronously with the moving fixed strip, keeping the output end of the dispensing machine always located on the perpendicular bisector of the minimum connecting line between the positioning stop and the moving fixed strip on opposite sides, the following features are specifically designed: The top bonding strip is provided with a first hinge seat and a second hinge seat with their hinge axes in a vertical position; the horizontal connecting line between the first and second hinge seats is parallel to the length direction of the top bonding strip; the first hinge seat is fixedly installed at one end of the top bonding strip, ensuring that the hinge axis of the first hinge seat falls within the surface plane of the positioning stop facing the moving fixed strip. Inside, the second hinge seat is slidably mounted on the top fitting strip and fixedly connected to one end of the movable fixing strip. The hinge axis of the second hinge seat falls into the surface plane of the movable fixing strip facing the positioning stop. The first hinge seat and the second hinge seat are respectively hinged with hinge arms of equal length. The free ends of the two hinge arms are coaxially mounted at the vertical connecting rod. The bottom of the automatic positioning bracket is respectively equipped with a connecting plate. The connecting plate is provided with an oblong hole extending along the length direction of the positioning stop. The connecting rod is limited and inserted into the oblong hole. The diameter of the connecting rod matches the width of the oblong hole.

[0006] To ensure that the automatic positioning bracket moves only along the length of the top bonding strip when driven by the connecting rod, the following features are specifically provided: horizontal guide rods are provided at both ends of the worktable, the guide rods are parallel to the length of the top bonding strip, and guide sleeves coaxial with the guide rods are provided at both ends of the automatic positioning bracket, the guide sleeves being respectively fitted onto the guide rods.

[0007] To enable the output end of the dispensing machine to move and rise with the drive assembly when the automatic positioning bracket is adjusted to any position, the following features are specifically provided: a sliding sleeve is slidably installed on the top of the automatic positioning bracket, the sliding sleeve moves along the length direction of the automatic positioning bracket, the output end of the dispensing machine is fixedly installed on the mounting frame, and the mounting frame is slidably installed in the sliding sleeve through a vertically extending extension slide.

[0008] Preferably, the drive assembly includes a first linear driver and a second linear driver. The working end of the first linear driver moves along the length direction of the positioning stop, and the second linear driver is fixedly installed on the working end of the first linear driver. The working end of the second linear driver is arranged to move in the vertical direction. A linear guide rail extending horizontally along the length direction of the top fitting strip is provided on the working end of the second linear driver. A limiting slide is provided on the mounting bracket, and the mounting bracket is slidably installed on the linear guide rail through the limiting slide.

[0009] To ensure the centering effect of the dispensing machine's output end, the following feature is specifically designed: the output end of the dispensing machine is located on the extension line of the center line of the oblong hole.

[0010] To ensure the processing of full-size door frame strips, the following features are specifically designed: the length of the positioning stop is greater than the length of the positioning stop, and the travel distance of the working end of the first linear drive is greater than the length of the positioning stop.

[0011] In order to achieve precise alignment of the initial working position of the dispensing machine's working end with the top of the door frame strip, the following features are specifically designed: a starting point positioning groove with a semi-circular cross-section is provided on one side of the top bonding strip that is bonded to the door frame strip, and the radius of the starting point positioning groove matches the radius of the dispensing machine's output end.

[0012] Preferably, a travel limit block is installed on the moving path of the working end of the first linear driver on the worktable. The travel limit block is located on the side of the worktable near the top bonding strip. When the working end of the first linear driver is in contact with the travel limit block, the working end of the dispensing machine is coaxially located in the starting point positioning groove.

[0013] The advantages of this invention compared to the prior art are as follows: By coordinating the positioning stop, the top bonding strip, and the moving fixing strip, this invention can quickly complete the clamping and positioning of door frame strips of different lengths and widths. At the same time, relying on the synchronous movement of the automatic positioning bracket and the moving fixing strip, it can ensure that the output end of the dispensing machine is always aligned with the center of the door frame strip without manual or sensor adjustment. This fundamentally solves the problem of excessively high hardware costs in existing intelligent adjustment solutions, and completely eliminates the extra time consumption per unit caused by sensor fine-tuning, avoiding extended dispensing cycle time and significantly improving production line operating efficiency.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 8 : A smart adhesive dispensing method for door frame strips includes the following steps: S1. Based on the length, width, and thickness of the door frame strip to be processed, set the dispensing parameters of the dispensing machine, including the dispensing distance and dispensing method; S2. Position the door frame strip to be processed and drive the dispensing machine to move to the initial position at one end of the door frame strip; S3. Drive the dispensing machine to move automatically to dispense adhesive; S4. Reset the dispensing machine, replace the sliding door frame strip, and repeat S2-S3 until all dispensing is completed.

[0026] To enable the dispensing machine's output end to automatically align with the center of door frame strips 4 of different widths without adjustment, the following features are specifically designed: A smart dispensing device for door frame strips, applied to a smart dispensing method for door frame strips, includes a worktable 1, a dispensing assembly 2, and a driving assembly 3. A positioning stop 1a and a top bonding strip 1b are fixedly installed on the worktable 1. The top bonding strip 1b is perpendicular to and bonded to one end of the positioning stop 1a. A movable fixing strip 1c, parallel to the positioning stop 1a, is slidably installed on one side of the worktable 1. The movable fixing strip 1c is equipped with a position locking structure. The movable fixing strip 1c, in conjunction with the positioning stop 1a and the top bonding strip 1b, clamps and fixes the door frame strip 4. The driving assembly 3 drives the dispensing assembly 2 to move along the length direction of the positioning stop 1a. The dispensing assembly 2 includes a dispensing machine 2a and an automatic positioning bracket 2b. The dispensing machine 2a is slidably installed at the center of the automatic positioning bracket 2b. The automatic positioning bracket 2b moves synchronously with the movable fixing strip 1c and always includes the output end of the dispensing machine 2a located on the perpendicular bisector of the minimum connecting line between the positioning stop 1a and the movable fixing strip 1c on opposite sides.

[0027] like Figures 1 to 8As shown, in this embodiment, during operation, the end of the door frame strip 4 to be processed is first attached to the top attachment strip 1b, and the side of the door frame strip 4 is pressed against the positioning stop 1a. Then, the movable fixing strip 1c is pushed to slide along the worktable 1, so that the movable fixing strip 1c cooperates with the positioning stop 1a to clamp the door frame strip 4, and locking is completed by the position locking structure of the movable fixing strip 1c. This adapts to door frame strips 4 of different lengths and widths, and completes the quick clamping and fixing of the workpiece. In this embodiment, the movable fixing strip 1c can be installed on the working end of a linear actuator such as an electric push rod, hydraulic cylinder or pneumatic cylinder, and move along the length direction of the top attachment strip 1b in conjunction with the drive of electrical components to achieve clamping of the door frame strip 4 and locking of its own position. It can also rely on Figure 1 As shown, the movable fixing strip 1c is inserted into the guide sleeve on the surface of the workbench 1 via a guide rod. The locking bolts screwed onto the guide sleeve lock the strip in place. The locking mechanism is not simple and will not be elaborated further here. During the movement of the movable fixing strip 1c, the automatic positioning bracket 2b moves synchronously with it to adjust its position. This ensures that the output end of the dispensing machine 2a, which is slidably mounted at the center of the automatic positioning bracket 2b, is located on the perpendicular bisector of the minimum connecting line between the positioning stop 1a and the movable fixing strip 1c on opposite sides. This ensures automatic alignment of the dispensing machine 2a's output end with the center of the door frame strip 4. Therefore, once the movable fixing strip 1c is locked in place, the drive assembly 3 is immediately activated, driving the dispensing assembly 2 to move along the length of the positioning stop 1a. During this movement, the dispensing machine 2a simultaneously completes the continuous dispensing operation of the door frame strip 4. This embodiment, through the cooperation of the positioning stop 1a, the top bonding strip 1b, and the movable fixing strip 1c with a position locking structure, can quickly complete the clamping and positioning of door frame strips 4 of different lengths and widths, solving the problem of adapting equipment for door frame strips 4 of different specifications. At the same time, relying on the synchronous follow-up of the automatic positioning bracket 2b and the movable fixing strip 1c, the output end of the dispensing machine 2a can always be aligned with the center of the door frame strip 4 without manual or system adjustment. This fundamentally solves the problem of excessively high hardware costs in existing intelligent adjustment solutions, and completely eliminates the extra time consumption per unit caused by sensor fine-tuning, avoiding extended dispensing cycle time and significantly improving production line operating efficiency.

[0028] To ensure that the automatic positioning bracket 2b moves synchronously with the moving fixing bar 1c, so that the output end of the dispensing machine 2a is always located on the perpendicular bisector of the minimum connecting line between the positioning bracket 1a and the moving fixing bar 1c on opposite sides, the following features are specifically designed: The top bonding strip 1b is provided with a first hinge seat 1b1 and a second hinge seat 1b2 with the hinge axis in a vertical state. The horizontal connecting line of the first hinge seat 1b1 and the second hinge seat 1b2 is parallel to the length direction of the top bonding strip 1b. The first hinge seat 1b1 is fixedly installed on one end of the top bonding strip 1b, and the hinge axis of the first hinge seat 1b1 is kept within the surface plane of the positioning stop 1a facing the moving fixing strip 1c. The second hinge seat 1b2 is slidably installed on the top bonding strip 1b and fixedly connected to one end of the moving fixing strip 1c. The hinge axis of b2 falls into the surface plane of the movable fixing bar 1c facing the positioning stop 1a; the first hinge seat 1b1 and the second hinge seat 1b2 are respectively hinged with hinge arms 1b3 of equal length. The free ends of the two hinge arms 1b3 are coaxially installed at the vertical connecting rod 1b4. The bottom of the automatic positioning bracket 2b is respectively equipped with a connecting plate 2b1. The connecting plate 2b1 is provided with a waist-shaped hole 2b2 extending along the length direction of the positioning stop 1a. The connecting rod 1b4 is limited and inserted into the waist-shaped hole 2b2. The diameter of the connecting rod 1b4 matches the width of the waist-shaped hole 2b2.

[0029] like Figure 2 and Figure 6 As shown, in this embodiment, when the movable fixing strip 1c slides along the workbench 1 to adapt to door frame strips 4 of different widths, the second hinge seat 1b2, which is fixedly connected to one end of the movable fixing strip 1c, slides synchronously along the top fitting strip 1b, synchronously changing the distance between the second hinge seat 1b2 and the first hinge seat 1b1 fixedly installed on the top fitting strip 1b; because the hinge axis of the first hinge seat 1b1 falls into the surface plane of the positioning stop 1a facing the movable fixing strip 1c, and the hinge axis of the second hinge seat 1b2 falls into the surface plane of the movable fixing strip 1c facing the positioning stop 1a, and the two hinge arms 1b3 respectively hinged on the first hinge seat 1b1 and the second hinge seat 1b2 are of equal length, therefore the two hinges The vertical connecting rod 1b4, coaxially mounted on the free end of arm 1b3, is always on the perpendicular bisector of the line connecting the first hinge seat 1b1 and the second hinge seat 1b2, that is, always on the perpendicular bisector of the minimum connecting line on the opposite side of the positioning stop 1a and the moving fixing strip 1c. In this embodiment, the connecting rod 1b4 is limited and inserted into the waist-shaped hole 2b2 of the bottom connecting plate 2b1 of the automatic positioning bracket 2b. The design of the waist-shaped hole 2b2 extending along the length direction of the positioning stop 1a makes the movement of the connecting rod 1b4 in the length direction of the top fitting strip 1b drive the automatic positioning bracket 2b to move synchronously, thereby ensuring that the output end of the dispensing machine 2a installed on the automatic positioning bracket 2b is always aligned with the center of the width of the door frame strip 4.

[0030] To ensure that the automatic positioning bracket 2b moves only along the length of the top bonding strip 1b when driven by the connecting rod 1b4, the following features are specifically designed: The workbench 1 has horizontal guide rods 1d at both ends, and the guide rods 1d are parallel to the length direction of the top bonding strip 1b. The automatic positioning bracket 2b has guide sleeves 2b3 at both ends, which are coaxial with the guide rods 1d and are respectively fitted onto the guide rods 1d.

[0031] like Figure 3 and Figure 5 As shown, in this embodiment, the coaxial sliding cooperation between the guide rod 1d and the guide sleeve 2b3 provides precise motion constraints for the automatic positioning bracket 2b, preventing the automatic positioning bracket 2b from shifting its posture when driven by the connecting rod 1b4, and ensuring the accuracy of centering positioning.

[0032] To ensure that the output end of the dispensing machine 2a can move up and down and follow the drive assembly 3 when the automatic positioning bracket 2b is adjusted to any position, the following features are specifically designed: A sliding sleeve 2c is slidably installed on the top of the automatic positioning bracket 2b. The sliding sleeve 2c moves along the length of the automatic positioning bracket 2b. The output end of the dispensing machine 2a is fixedly installed on the mounting frame 2a1. The mounting frame 2a1 is slidably installed in the sliding sleeve 2c through a vertically extending extension strip 2a2.

[0033] The drive assembly 3 includes a first linear driver 3a and a second linear driver 3b. The working end of the first linear driver 3a moves along the length direction of the positioning stop 1a. The second linear driver 3b is fixedly installed on the working end of the first linear driver 3a. The working end of the second linear driver 3b is set to move in the vertical direction. A linear guide rail 3b1 extending horizontally along the length direction of the top bonding strip 1b is provided on the working end of the second linear driver 3b. A limiting slide 2a3 is provided on the mounting frame 2a1. The mounting frame 2a1 is slidably installed on the linear guide rail 3b1 through the limiting slide 2a3.

[0034] like Figures 4 to 8As shown, in this embodiment, the mounting bracket 2a1, which is fixedly connected to the output end of the dispensing machine 2a, slides synchronously along the linear guide rail 3b1 of the working end of the second linear driver 3b via the limiting slide 2a3 on it, thereby adapting to the width position change of the automatic positioning bracket 2b. When it is necessary to control the vertical working height of the output end of the dispensing machine 2a, the working end of the second linear driver 3b moves in the vertical direction, driving the linear guide rail 3b1 to rise and fall synchronously. The limiting slide 2a3 drives the mounting bracket 2a1 to complete the rising and falling action synchronously. At this time, the mounting bracket 2a1 moves along the inner sleeve 2c via the vertically extending extension strip 2a2. The door frame strip 4 slides vertically. When performing continuous dispensing operations, the first linear actuator 3a is activated, and its working end moves along the length of the positioning stop 1a, driving the second linear actuator 3b to move synchronously. Through the cooperation of the linear guide rail 3b1 and the limiting slide 2a3, the mounting frame 2a1 and the dispensing machine 2a move along the length of the positioning stop 1a. At this time, the mounting frame 2a1 drives the sliding sleeve 2c to slide synchronously along the length of the automatic positioning bracket 2b through the extension slide 2a2, maintaining the centered positioning state of the dispensing machine 2a throughout the process, and completing the continuous and precise dispensing operation of the entire length of the door frame strip 4. In this embodiment, the first linear actuator 3a can be a transmission belt with a slide rail, or it can be a lead screw slide table or other existing technologies. In this embodiment, the second linear actuator 3b can be a cylinder, a hydraulic cylinder, an electric push rod, or a linear slide table.

[0035] like Figure 2 As shown, in order to ensure the alignment effect at the output end of the dispensing machine 2a, the following features are specifically designed: The output end of the dispensing machine 2a is located on the extension line of the center line of the waist-shaped hole 2b2.

[0036] like Figure 5 As shown, in order to ensure the processing of the full-size door frame strip 4, the following features are specifically set: The length of the positioning stop 1a is greater than 3000mm, and the travel of the working end of the first linear actuator 3a is greater than the length of the positioning stop 1a.

[0037] In this embodiment, the positioning stop 1a is set to a length of more than 3000mm, which fully covers the conventional size requirements of most door frame strips 4 of 600mm-2800mm in the door and window and custom furniture industry. The design that the travel of the working end of the first linear drive 3a is greater than the length of the positioning stop 1a fundamentally eliminates the travel blind zone of the dispensing operation and ensures that door frame strips 4 of any suitable length can achieve continuous and uniform dispensing along the entire length.

[0038] To ensure precise alignment of the initial working position of the dispensing machine 2a with the top of the door frame strip 4, the following features are specifically designed: The top bonding strip 1b is provided with a semi-circular starting positioning groove 1b5 on one side of the door frame strip 4. The radius of the starting positioning groove 1b5 matches the radius of the output end of the dispensing machine 2a.

[0039] The worktable 1 is mounted on the moving path of the working end of the first linear driver 3a and has a travel limit block 1e installed on it. The travel limit block 1e is located on the side of the worktable 1 near the top bonding strip 1b. When the working end of the first linear driver 3a is in contact with the travel limit block 1e, the working end of the dispensing machine 2a is coaxially located in the starting point positioning groove 1b5.

[0040] like Figure 2 , Figure 7 and Figure 8 As shown, the first linear actuator 3a drives the working end to move to the side of the worktable 1 near the top bonding strip 1b and to fit into the travel limit block 1e. At this time, the working end of the dispensing machine 2a falls coaxially into the starting point positioning groove 1b5 on the top bonding strip 1b. Since the cross-section of the starting point positioning groove 1b5 is semi-circular and its radius matches the radius of the output end of the dispensing machine 2a, the working end of the dispensing machine 2a can be precisely aligned with the top position of the door frame strip 4, providing a uniform and precise starting point for subsequent continuous dispensing along the length of the door frame strip 4.

[0041] Working principle: During operation, the end of the door frame strip 4 to be processed is first attached to the top attachment strip 1b, and the side of the door frame strip 4 is pressed against the positioning stop 1a. Then, the moving fixing strip 1c is pushed to slide along the worktable 1, so that the moving fixing strip 1c cooperates with the positioning stop 1a to clamp the door frame strip 4, and the locking structure of the moving fixing strip 1c is used to lock it, thus completing the quick clamping and fixing of the workpiece. During the movement of the moving fixing strip 1c, the automatic positioning bracket 2b moves synchronously with the moving fixing strip 1c to adjust its position, always ensuring that the output end of the dispensing machine 2a, which is slidably installed in the center of the automatic positioning bracket 2b, is located on the perpendicular bisector of the minimum connecting line on the opposite side of the positioning stop 1a and the moving fixing strip 1c. Then, the drive component 3 is started, and the dispensing component 2 moves along the length direction of the positioning stop 1a. During the movement, the dispensing machine 2a completes the continuous dispensing operation of the door frame strip 4.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
