Description

Technical Field

[0001] This invention relates to honeycomb panel production equipment and methods, specifically to an automatic glue-applying equipment and method for honeycomb panels. Background Technology

[0002] Honeycomb panels have advantages such as being lightweight, having low installation load, extremely high flatness, being resistant to deformation, having a high safety factor, good sound insulation, strong corrosion resistance, high energy efficiency, and low pollution. They have become an important building construction material and are frequently used in ceilings and other parts of modern buildings. In addition, at the end of the lifespan of metal products, they can be recycled and reused to produce metal, resulting in a high recycling rate.

[0003] A honeycomb panel is a board made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material. It is also called a honeycomb sandwich structure. Finally, the sides of the sandwich structure are sealed to prevent the internal structure from being exposed.

[0004] In the current honeycomb panel manufacturing process, although automatic glue-applying equipment is used to apply glue to the panels, replacing manual glue application and significantly improving work efficiency, the existing automatic glue-applying equipment still has the following shortcomings:

[0005] See Figure 1-2 When the glue application begins, the panel remains stationary while the glue gun with multiple nozzles moves laterally to spray glue onto the panel. Then, the conveyor mechanism drives the panel to move, and the glue gun moves back and forth laterally. At this time, the glue strip sprayed on the panel is in an inclined state. In order to ensure that glue is applied to every spot, glue will inevitably overlap at the beginning and end of two adjacent strokes. This not only wastes glue but also affects the efficiency of glue application. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems and provide an automatic glue application device for honeycomb panels. This automatic glue application device can avoid glue overlap, which not only saves glue but also improves glue application efficiency.

[0007] Another object of the present invention is to provide an automatic glue application method for honeycomb panels.

[0008] The objective of this invention is achieved through the following technical solution:

[0009] An automatic glue-applying device for honeycomb panels includes a panel conveying mechanism for conveying panels and a glue-applying mechanism for applying glue to the panels.

[0010] The glue application mechanism includes a glue application guide structure, a glue gun, and a glue application drive mechanism. The glue application guide structure is located above the panel conveying channel and includes a guide frame and a swing guide rod. The guide frame has a vertically penetrating limiting guide space, which is formed by two isosceles triangular limiting guide holes connected apically. The swing guide rod is rotatably connected to the guide frame, and its rotation center is located on the side near the upstream end of the panel conveying channel where the two limiting guide holes are connected apically. The swing guide rod is rotatably connected to the guide frame, and its rotation center is located on the side near the upstream end of the panel conveying channel where the rotation center of the swing guide rod is the boundary. One end of the rod is a swing guide, and the other end of the swing guide is a stroke limiter. The guide frame is provided with two limiters for limiting the horizontal swing of the stroke limiter of the swing guide. The two limiters are symmetrically arranged about the rotation center of the swing guide. When the stroke limiter of the swing guide contacts the limiter, under vertical projection, the gap between the swing guide and the side wall of the limiter hole near the downstream of the panel conveying channel forms a distal limiter channel, and the gap between the end of the swing guide and the bottom surface of the limiter hole forms a teleportation channel.

[0011] The glue gun includes a nozzle and a barrel; the nozzle is provided with multiple nozzles; the barrel is connected to the glue dispensing drive mechanism via a linear sliding structure.

[0012] The glue-applying drive mechanism includes a transverse moving plate, a transverse drive mechanism, and a longitudinal drive mechanism; the driving direction of the transverse drive mechanism is perpendicular to the extension direction of the panel conveying channel; the longitudinal drive mechanism is disposed on the transverse moving plate and includes a longitudinal drive spring and a longitudinal push block; the linear sliding structure includes a linear sliding hole and a limiting block, the linear sliding hole being formed on the transverse moving plate; the gun rod passes upward through the limiting guide space and the linear sliding hole and is fixedly connected to the limiting block; the longitudinal drive spring and the longitudinal push block are both disposed in the linear sliding hole, the two ends of the longitudinal drive spring respectively abutting against the hole wall of the linear sliding hole and the longitudinal push block, and the longitudinal push block is located between the gun rod and the longitudinal drive spring.

[0013] In a preferred embodiment of the present invention, the lateral drive mechanism includes a lateral drive motor and a lateral transmission assembly, the lateral transmission assembly including a lateral transmission screw and a lateral transmission screw nut; the lateral transmission screw nut is fixedly connected to the lateral moving plate.

[0014] In a preferred embodiment of the present invention, the panel conveying mechanism includes a conveyor belt, drive rollers, and a conveyor motor. Two drive rollers are provided and rotatably connected to the conveyor frame. The conveyor belt is disposed on the two drive rollers. The output shaft of the conveyor motor is connected to one of the drive rollers.

[0015] In a preferred embodiment of the present invention, the panel conveying mechanism includes a conveying limiting structure. Two sets of this conveying limiting structure are respectively arranged opposite each other on both sides of the panel conveying channel. Each set of conveying limiting structures includes a mounting block and a limiting roller. The mounting block is fixed to the conveyor frame. The limiting roller is rotatably connected to the mounting block, and its axis is parallel to the vertical direction. This structure allows the panel to be limited and conveyed downwards along a specified path.

[0016] Furthermore, each set of conveying limiting structures includes two conveying limiting structures, and the arrangement direction of the two conveying limiting structures is parallel to the extension direction of the panel conveying channel.

[0017] An automatic glue application method for honeycomb panels includes the following steps:

[0018] The panel to be glued is placed on the panel conveying channel of the panel conveying mechanism. The panel is then conveyed by the panel conveying mechanism to the area below the glue-applying guide structure, so that the front end of the panel is directly below the nozzle of the spray head. At this time, the spray bar is in contact with the side wall of one of the limiting guide holes near the upstream of the panel conveying channel, and the swing guide part of the swing guide rod is located in the limiting guide hole.

[0019] The panel continues to be conveyed downwards by the panel conveying mechanism, while the lateral moving plate is driven to move laterally by the lateral drive mechanism. During the lateral movement, the lateral moving plate is passively squeezed by the side wall of one of the limiting guide holes. The glue gun moves obliquely to the opposite side along the side wall of the limiting guide hole and compresses the longitudinal drive spring through the longitudinal push block along the straight sliding hole. The component of the glue gun's oblique movement parallel to the panel's movement direction is the same as the panel's movement speed. When the glue gun contacts the swing guide part of the swing guide rod, it drives the swing guide part to swing towards the other limiting guide hole until the swing guide part of the swing guide rod is blocked by the limiting rod near one of the limiting guide holes. At this time, the swing guide part of the swing guide rod is located in the other limiting guide hole. The swing guide part of the swing guide rod is equivalent to the extension line of the side wall of one of the limiting guide holes near the upstream of the panel conveying channel. At the same time, glue is sprayed onto the panel downwards through multiple nozzles of the glue gun, creating glue strips perpendicular to the panel's movement direction.

[0020] When the glue gun enters another limiting guide hole, the swaying guide part of the glue gun continues to move forward at an angle in the far-end limiting channel, while the swaying guide part remains stationary due to the obstruction of the limiting rod near one of the limiting guide holes. When the glue gun enters the instantaneous channel of another limiting guide hole from the far-end limiting channel, the longitudinal drive spring instantly releases its potential energy and recovers its deformation, and quickly pushes the glue gun towards the side wall of the other limiting guide hole near the upstream of the panel conveying channel through the longitudinal push block, so that the glue gun instantly moves from the previous glue application position to the next glue application position.

[0021] The lateral moving plate is driven in the opposite direction by the lateral drive mechanism to perform lateral reset; during the reset process, the glue gun moves obliquely to the opposite side along the side wall of another limit guide hole while maintaining glue spraying, and compresses the longitudinal drive spring through the longitudinal push block along the straight sliding hole; when the glue gun contacts the swing guide part of the swing guide rod, it drives the swing guide part to swing in the direction of one of the limit guide holes until the swing guide part of the swing guide rod is blocked by the limit rod near the other limit guide hole. At this time, the swing guide part of the swing guide rod is located in one of the limit guide holes. The swing guide part of the swing guide rod is equivalent to the extension line of the side wall of the other limit guide hole near the upstream of the panel conveying channel.

[0022] When the glue gun enters another limiting guide hole, the glue gun continues to move forward at an angle in the far-end limiting channel, following the swing guide part of the swing guide rod. At this time, the swing guide part remains stationary due to the obstruction of the limiting rod near the other limiting guide hole. When the glue gun enters the instantaneous channel of one of the limiting guide holes from the far-end limiting channel, the longitudinal drive spring instantly releases its potential energy and recovers its deformation. It then quickly pushes the glue gun towards the side wall of one of the limiting guide holes near the upstream of the panel conveying channel through the longitudinal push block, causing the glue gun to instantly move from the previous glue application position to the next glue application position. At this time, the glue gun returns to the initial position of the guide frame and the next round of glue application begins until the glue application of the entire panel is completed.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The automatic glue applicator for honeycomb panels of the present invention drives the glue gun to move at an angle to the opposite side, ensuring that the component of the glue gun's angled movement parallel to the panel's movement direction is the same as the panel's movement speed. This allows glue strips to be applied to the panel perpendicular to its movement direction, effectively preventing glue overlap and reducing glue waste.

[0025] 2. By setting a longitudinal drive mechanism, when the glue gun enters the instantaneous transfer channel of another limit guide hole from the far-end limit channel, the longitudinal drive spring instantly releases potential energy to restore deformation, so that the glue gun instantly moves from the previous glue position to the next glue position, reducing glue waste.

[0026] 3. By setting up a guide frame and a swing guide rod, an extension line can be created in the two lateral movement strokes of the glue gun, ensuring that the glue gun can draw a complete parallel glue strip on the panel, which is very ingenious. Attached Figure Description

[0031] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0032] See Figure 3-4 The automatic glue-applying equipment for honeycomb panels in this embodiment includes a panel conveying mechanism for conveying panels and a glue-applying mechanism for applying glue to the panels; wherein, the panel conveying mechanism includes a conveyor belt 1, a drive roller and a conveyor motor 2, the drive roller is provided with two and rotatably connected to the conveyor frame; the conveyor belt 1 is arranged on the two drive rollers; the output shaft of the conveyor motor 2 is connected to one of the drive rollers.

[0033] See Figure 3-4 The panel conveying mechanism includes a conveying limiting structure, which has two sets arranged opposite each other on both sides of the panel conveying channel. Each set of conveying limiting structures includes a mounting block 3 and a limiting roller 4. The mounting block 3 is fixed to the conveyor frame; the limiting roller 4 is rotatably connected to the mounting block 3, and the axis of the limiting roller 4 is parallel to the vertical direction. This structure allows the panel to be limited and conveyed downwards along a designated path.

[0034] Furthermore, each set of conveying limiting structures includes two conveying limiting structures, and the arrangement direction of the two conveying limiting structures is parallel to the extension direction of the panel conveying channel.

[0035] See Figure 3-6The glue application mechanism includes a glue application guide structure, a glue gun 5, and a glue application drive mechanism. The glue application guide structure is located above the panel conveying channel and includes a guide frame 6 and a swing guide rod 7. The guide frame 6 has a vertically penetrating limiting guide space, which is formed by two isosceles triangular limiting guide holes 6-1 connected apically. The swing guide rod 7 is rotatably connected to the guide frame 6, and the rotation center of the swing guide rod 7 is located on the side near the upstream of the panel conveying channel where the two limiting guide holes 6-1 are connected apically. Taking the rotation center of the swing guide rod 7 as the boundary, the swing guide rod 7... One end is a swing guide part, and the other end of the swing guide rod 7 is a stroke limit part; the guide frame 6 is provided with two limit rods 8 for limiting the horizontal swing of the stroke limit part of the swing guide rod 7; the two limit rods 8 are symmetrically arranged about the rotation center of the swing guide rod 7; when the stroke limit part of the swing guide rod 7 contacts the limit rod 8, under vertical projection, the gap between the swing guide part of the swing guide rod 7 and the side wall of the limit guide hole 6-1 near the downstream of the panel conveying channel constitutes the far end limit channel 9, and the gap between the end of the swing guide part of the swing guide rod 7 and the bottom surface of the limit guide hole 6-1 constitutes the instantaneous transfer channel 10.

[0036] See Figure 3-6 The glue gun 5 includes a nozzle 5-1 and a gun rod 5-2. The nozzle 5-1 is provided with multiple nozzles. The gun rod 5-2 is connected to the glue dispensing drive mechanism through a linear sliding structure.

[0037] See Figure 3-6 The glue-applying drive mechanism includes a transverse moving plate 11, a transverse drive mechanism, and a longitudinal drive mechanism. The driving direction of the transverse drive mechanism is perpendicular to the extension direction of the panel conveying channel. The longitudinal drive mechanism is disposed on the transverse moving plate 11 and includes a longitudinal drive spring 12 and a longitudinal push block 13. The linear sliding structure includes a linear sliding hole 11-1 and a limiting block 14. The linear sliding hole 11-1 is opened on the transverse moving plate 11. The gun rod 5-2 passes upward through the limiting guide space and the linear sliding hole 11-1 and is fixedly connected to the limiting block 14. The longitudinal drive spring 12 and the longitudinal push block 13 are both disposed in the linear sliding hole 11-1. The two ends of the longitudinal drive spring 12 abut against the hole wall of the linear sliding hole 11-1 and the longitudinal push block 13, respectively. The longitudinal push block 13 is located between the gun rod 5-2 and the longitudinal drive spring 12.

[0038] See Figure 3-4 The lateral drive mechanism includes a lateral drive motor 15 and a lateral transmission assembly. The lateral transmission assembly includes a lateral transmission screw 16 and a lateral transmission screw nut. The lateral transmission screw nut is fixedly connected to the lateral moving plate 11.

[0039] See Figure 6-10 The automatic glue application method for honeycomb panels in this embodiment includes the following steps:

[0040] The panel to be glued is placed on the panel conveying channel of the panel conveying mechanism. The panel is then conveyed by the panel conveying mechanism to the area below the glue-applying guide structure, so that the front end of the panel is directly below the nozzle of the spray head 5-1. At this time, the spray bar is in contact with the side wall of one of the limiting guide holes 6-1 near the upstream of the panel conveying channel, and the swing guide part of the swing guide rod 7 is located in the limiting guide hole 6-1.

[0041] The panel continues to be conveyed downwards by the panel conveying mechanism. Simultaneously, the transverse driving mechanism drives the transverse moving plate 11 to move laterally. Because the spray bar is in contact with the side wall of the isosceles triangular limiting guide hole 6-1, during the transverse movement of the transverse moving plate 11, it is passively squeezed by the side wall of one of the limiting guide holes 6-1. The glue gun 5 moves obliquely to the opposite side along the side wall of this limiting guide hole 6-1, and compresses the longitudinal driving spring 12 along the linear sliding hole 11-1 via the longitudinal push block 13. Figure 6 When the glue gun 5 contacts the swing guide part of the swing guide rod 7, it drives the swing guide part to swing towards another limiting guide hole 6-1 until the swing guide part of the swing guide rod 7 is blocked by the limiting rod 8 near one of the limiting guide holes 6-1. At this time, the swing guide part of the swing guide rod 7 is located in the other limiting guide hole 6-1. The swing guide part of the swing guide rod 7 is equivalent to the extension line of the side wall of one of the limiting guide holes 6-1 near the upstream of the panel conveying channel. At the same time, glue is sprayed onto the panel below through the multiple nozzles of the glue gun 5. The component of the glue gun 5 that moves at an angle parallel to the direction of panel movement is the same as the speed of panel movement, so that a glue strip perpendicular to the direction of panel movement can be applied to the panel.

[0042] When the glue gun 5 enters another limiting guide hole 6-1, the glue gun 5 continues to move forward at an angle in the distal limiting channel 9, following the swing guide part of the swing guide rod 7. At this time, the swing guide part remains stationary due to the obstruction of the limiting rod 8 near one of the limiting guide holes 6-1. Figure 7 When the glue gun 5 enters the instantaneous transfer channel 10 of another limiting guide hole 6-1 from the remote limiting channel 9, since there is no longer a limit or obstruction in the longitudinal direction, the longitudinal drive spring 12 instantly releases its potential energy and recovers its deformation. Through the longitudinal push block 13, it quickly pushes the glue gun 5 towards the side wall of the other limiting guide hole 6-1 near the upstream of the panel conveying channel, causing the glue gun 5 to instantly transfer from the previous glue application position to the next. Figure 8 This can effectively prevent glue from overlapping and reduce glue waste.

[0043] The lateral moving plate 11 is driven in the opposite direction by the lateral drive mechanism to perform lateral reset; during the reset process, the glue gun 5, while maintaining glue spraying, moves obliquely to the opposite side along the side wall of another limiting guide hole 6-1, and compresses the longitudinal drive spring 12 through the longitudinal push block 13 along the straight sliding hole 11-1, as shown. Figure 9 Since the swing guide part of the swing guide rod 7 is stopped in another limiting guide hole 6-1, when the glue gun 5 contacts the swing guide part of the swing guide rod 7, it will drive the swing guide part to swing in the direction of one of the limiting guide holes 6-1 until the swing guide part of the swing guide rod 7 is blocked by the limiting rod 8 near the other limiting guide hole 6-1. At this time, the swing guide part of the swing guide rod 7 is located in one of the limiting guide holes 6-1. The swing guide part of the swing guide rod 7 is equivalent to the extension line of the side wall of the other limiting guide hole 6-1 near the upstream of the panel conveying channel.

[0044] When the glue gun 5 enters another limiting guide hole 6-1, the glue gun 5 continues to move forward at an angle in the distal limiting channel 9, following the swing guide part of the swing guide rod 7. At this time, the swing guide part is blocked by the limiting rod 8 near the other limiting guide hole 6-1 and remains stationary. When the glue gun 5 enters the instantaneous channel 10 of one of the limiting guide holes 6-1 from the distal limiting channel 9, as... Figure 10 The longitudinal drive spring 12 instantly releases its potential energy to recover its deformation, and through the longitudinal push block 13, quickly pushes the glue gun 5 towards one of the limiting guide holes 6-1 on the side wall near the upstream of the panel conveying channel. This causes the glue gun 5 to instantly move from the previous glue application position to the next. At this point, the glue gun 5 returns to the initial position of the guide frame 6, and then the next round of glue application begins, until the entire panel is glued. After one round of lateral back-and-forth movement, two glue application operations can be completed in parallel without overlap, which not only saves glue but also improves glue application efficiency.

[0045] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
