Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and in particular to an automatic layer alignment board for assembling multi-layer boards. Background Technology

[0002] In the process of intelligent transformation of the wood processing industry, the automatic layup alignment board for multi-layer board assembly is a key piece of equipment. It undertakes the core task of accurately stacking, automatically laying and aligning veneers. Through the deep integration of automated mechanical structure and intelligent control system, it replaces the traditional manual assembly operation, which greatly improves the production efficiency and quality stability of plywood, particleboard and multi-layer wood products, and has become an indispensable part of the modern wood processing production line.

[0003] Early automated plywood aligning systems used fixed-size mechanical limit frames and single-sized vacuum adsorption devices. Due to their lack of flexible adjustment, these devices struggled to accurately fit veneers of varying thicknesses and widths. While existing equipment has incorporated electrically adjustable baffles and multi-modal suction cup structures to accommodate some size variations as wood processing demands have diversified, significant shortcomings remain. Currently, equipment typically relies on preset programs to control the extension and retraction distance of the electric baffles, using different modular suction cups to adsorb the veneers. However, when veneer dimensions exceed standard parameters, the electric adjustment mechanism, limited by its stroke and adjustment accuracy, cannot quickly respond to special size requirements. Furthermore, the fixed layout of the modular suction cups makes it difficult to conform to the edges of irregularly shaped wood, resulting in weak adsorption and veneer misalignment. This affects the accuracy of plywood assembly and limits the equipment's adaptability to customized wood processing scenarios. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic layering alignment plate for multi-layer board assembly, which aims to improve the problem in the prior art where the specifications of the wood veneer exceed the standard, and the suction cup is difficult to fit the edge of irregular wood due to the fixed layout, resulting in poor adhesion.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic layup alignment plate for multilayer board assembly, comprising an I-shaped bracket, a sliding plate, and a main substrate. Hydraulic rods are fixedly connected to the left and right sides of the bottom end of the sliding plate, and the telescopic ends of the two hydraulic rods are fixedly connected to the top end of the main substrate.

A lateral movement component is provided on the top of the sliding plate to drive the sliding plate to move.

[0006] The telescopic adjustment mechanism includes two telescopic plates, the outer walls of which are respectively disposed on the left and right sides of the main substrate. Multiple vacuum suction cups are fixedly connected to the bottom ends of both the telescopic plates and the main substrate.

Limiting rods are fixedly connected to the front and rear ends of adjacent sides of the two telescopic plates. Multiple limiting holes are opened on the outer wall of the main substrate. The outer walls of the limiting rods are slidably connected to the inner walls of the corresponding limiting holes. A telescopic drive assembly is disposed at the top center of the main substrate. A vacuum device is fixedly connected to the bottom center of the sliding plate. One end of the vacuum device is connected to a telescopic pipe, and the other end of the telescopic pipe is connected to the outer walls of the two rear vacuum suction cups via a connecting pipe.

The output end of the servo motor passes through the top of the U-shaped support plate and is fixedly connected to a drive gear. Telescopic racks are meshed on the front and rear sides of the outer wall of the drive gear. One adjacent side of the two telescopic plates is fixedly connected to one end of the corresponding telescopic rack. The outer walls of the two telescopic racks are slidably connected to the inner walls of the two sides of the U-shaped support plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the main substrate is driven to fall and fit against the board material by a hydraulic rod. Then, the vacuum equipment is started, and negative pressure is formed in all vacuum suction cups through the telescopic tube, connecting tube and corrugated tube. Multiple vacuum suction cups distributed at the bottom of the telescopic plate and the main substrate adsorb and fix the board material. The servo motor is started, which drives the drive gear to rotate, so that the telescopic racks on both sides slide along the inner wall of the U-shaped support plate to the sides or the middle. This causes the telescopic plate to extend and retract synchronously on the left and right sides of the main substrate, thereby adjusting the width to adapt to the board material size, so that it can adapt to board materials of different sizes.

[0023] 2. In this utility model, by rotating the rotating block, since the rotating block is fixedly connected to the screw and the screw is threadedly connected to the middle of the fixed plate, the rotating block rotates and drives the screw to move axially. The baffle connected to the left end of the screw slides on the front and back sides of the inner wall of the fixed plate through the limiting rod fixedly connected to it, thereby limiting the position of the sheet above the conveying device. When the sheet is conveyed to the position, the baffle blocks the sheet at the preset layup starting position. The mechanical limiting ensures the accurate position of the sheet, providing a guarantee for subsequent precise alignment. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an automatic layup alignment plate for multi-layer board assembly, including an I-shaped support 1, a sliding plate 4, and a main substrate 5. The I-shaped support 1 serves as the support frame of the equipment. Hydraulic rods 6 are fixedly connected to the left and right sides of the bottom of the sliding plate 4. The telescopic ends of the two hydraulic rods 6 are fixedly connected to the top of the main substrate 5. The sliding plate 4 is connected to the main substrate 5 through the hydraulic rods 6 on its left and right sides. Activating the hydraulic rods 6 drives the main substrate 5 to fall, so that the main substrate 5 fits the board material. The outer wall of the main substrate 5 is provided with a telescopic adjustment mechanism 2, which is used to adapt to boards of different specifications and sizes. The inner wall of the right I-shaped support 1 is provided with a limiting mechanism 3, which is used to limit the position of the board material above the conveying device. The top of the sliding plate 4 is provided with a lateral movement component 7, which is used to drive the sliding plate 4 to move.

[0033] The telescopic adjustment mechanism 2 includes two telescopic plates 21. The outer walls of the two telescopic plates 21 are respectively disposed on the left and right sides of the main substrate 5. Multiple vacuum suction cups 22 are fixedly connected to the bottom ends of the telescopic plates 21 and the main substrate 5. A connecting pipe 23 is connected to the adjacent side of the front and rear vacuum suction cups 22, and a corrugated pipe 24 is connected to the adjacent side of the two adjacent rear vacuum suction cups 22. Limiting rods 25 are fixedly connected to the front and rear ends of the adjacent side of the two telescopic plates 21. Multiple limiting holes 26 are opened on the outer wall of the main substrate 5. The outer wall of the limiting rod 25 is slidably connected to the inner wall of the corresponding limiting hole 26. The cooperation between the limiting rod 25 and the limiting hole 26 plays a guiding and limiting role during the telescopic plate 21's extension and retraction. A telescopic drive assembly 27 is provided at the top center of the main substrate 5. A vacuum device 28 is fixedly connected to the bottom center of the sliding plate 4. One end of the vacuum device 28 is connected to a telescopic tube 29. The other end of the telescopic tube 29 is connected to the outer wall of the two vacuum suction cups 22 in the rear center through a connecting tube 23. When the vacuum device 28 is activated, the vacuum device 28 creates a negative pressure inside all the vacuum suction cups 22 through the telescopic tube 29, the connecting tube 23 and the corrugated tube 24. Multiple vacuum suction cups 22 distributed on the telescopic plate 21 and the bottom of the main substrate 5 firmly adsorb and fix the plate material. Slide grooves 8 are opened on the adjacent sides of the two I-shaped brackets 1. The left and right sides of the sliding plate 4 are slidably connected to the inner wall of the corresponding slide grooves 8.

[0034] The telescopic drive assembly 27 includes a U-shaped support plate 271. The bottom end of the U-shaped support plate 271 is fixedly connected to the top center of the main base plate 5. A servo motor 272 is fixedly connected to the top end of the U-shaped support plate 271. The output end of the servo motor 272 passes through the top of the U-shaped support plate 271 and is fixedly connected to a drive gear 273. Telescopic racks 274 are meshed with the front and rear sides of the outer wall of the drive gear 273. Adjacent sides of the two telescopic plates 21 are respectively fixedly connected to one end of the corresponding telescopic rack 274. The outer wall of the retractable rack 274 is slidably connected to the inner walls of both sides of the U-shaped support plate 271. When the servo motor 272 is powered on, its output end drives the drive gear 273 to rotate. Since the drive gear 273 meshes with the telescopic racks 274 on the front and rear sides, the rotation of the drive gear 273 will cause the telescopic racks 274 on both sides to slide along the inner wall of the U-shaped support plate 271 to the sides or the middle. One end of the telescopic rack 274 is fixedly connected to the telescopic plate 21, thereby driving the telescopic plate 21 to extend and retract synchronously on the left and right sides of the main base plate 5.

[0035] Specifically, the I-beam bracket 1 serves as the support frame of the equipment. The sliding plate 4 is connected to the main base plate 5 via hydraulic rods 6 on its left and right sides. Before startup, the hydraulic rods 6 are in an initial retracted state, maintaining a certain distance between the sliding plate 4 and the main base plate 5. At this time, the sliding grooves 8 on the adjacent sides of the two I-beam brackets 1 cooperate with the left and right sides of the sliding plate 4 to guide the lateral movement of the sliding plate 4. The conveyor belt is placed at the bottom of the I-beam bracket 1, feeding the sheet material from the left side to directly below the device. At this time, the hydraulic rods 6 are activated to drive the main base plate 5 down, causing the main base plate 5 to fit against the sheet material. Subsequently, the vacuum device 28 is activated. The vacuum device 28, through the telescopic tube 29, connecting tube 23, and corrugated tube 24, creates negative pressure inside all the vacuum suction cups 22. Multiple vacuum suction cups distributed at the bottom of the telescopic plate 21 and the main base plate 5... The suction cup 22 firmly adheres to and fixes the sheet material, ensuring that it will not shift during subsequent operations. For sheets of different specifications, the servo motor 272 is powered on and started, and its output drives the drive gear 273 to rotate. Since the drive gear 273 meshes with the telescopic racks 274 on the front and rear sides, the rotation of the drive gear 273 will cause the telescopic racks 274 on both sides to slide along the inner wall of the U-shaped support plate 271 to the sides or the middle. One end of the telescopic rack 274 is fixedly connected to the telescopic plate 21, thereby driving the telescopic plate 21 to extend and retract synchronously on the left and right sides of the main base plate 5, adjusting the overall width to adapt to the sheet material size. At the same time, the cooperation between the limiting rod 25 and the limiting hole 26 plays a guiding and limiting role during the extension and retraction of the telescopic plate 21, ensuring that the telescopic plate 21 moves smoothly and is positioned accurately.

[0036] Reference Figure 1 , Figure 2 and Figure 3The limiting mechanism 3 includes a fixed plate 31. The outer wall of the fixed plate 31 is fixedly connected to the middle of the inner wall of the right I-shaped bracket 1. Limiting rods 32 are slidably connected to the front and rear sides of the inner wall of the fixed plate 31. Baffles 33 are fixedly connected to the left ends of the two limiting rods 32. A screw 34 is rotatably connected to the right end of the baffle 33. The outer wall of the screw 34 is threadedly connected to the middle of the fixed plate 31. The right end of the screw 34 passes through the right side of the fixed plate 31 and is fixedly connected to a rotating block 35.

[0037] Specifically, for different specifications of sheet metal, by rotating the rotating block 35, since the rotating block 35 is fixedly connected to the screw 34, and the screw 34 is threadedly connected to the middle of the fixed plate 31, the rotation of the rotating block 35 will drive the screw 34 to move axially. The baffle 33, which is rotatably connected to the left end of the screw 34, will slide on the front and rear sides of the inner wall of the fixed plate 31 under the push of the screw 34 through the limiting rod 32 fixedly connected to it. The sliding connection between the limiting rod 32 and the fixed plate 31 ensures the smoothness and straightness of the movement of the baffle 33, thereby limiting the position of the sheet metal above the conveying device. When the sheet metal is conveyed to the position, the baffle 33 will block the sheet metal at the preset layup start position. Through mechanical limiting, the sheet metal is ensured to be in the accurate position, providing a guarantee for subsequent precise alignment.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The lateral movement component 7 includes a stepper motor 71, the bottom end of which is fixedly connected to the middle of the top of the sliding plate 4. A drive bevel gear 72 is fixedly connected to the output end of the stepper motor 71. A hollow bevel gear 73 meshes with the outer wall of the drive bevel gear 72. The stepper motor 71 is fixed to the middle of the top of the sliding plate 4. When energized, the output end of the stepper motor 71 drives the drive bevel gear 72 to rotate. The drive bevel gear 72 meshes with the hollow bevel gear 73, transmitting the rotational motion to the hollow bevel gear 73. A rotating rod 74 is fixedly connected to the inner wall of the hollow bevel gear 73. Both the left and right ends of the rotating rod 74 are... A connecting gear 75 is fixedly connected, and a toothed plate 76 is fixedly connected to the top of the I-shaped bracket 1. The top of the toothed plate 76 meshes with the outer wall of the corresponding connecting gear 75, thereby driving the rotating rod 74, which is fixedly connected to the inner wall of the hollow bevel gear 73, to rotate. The connecting gears 75 at the left and right ends of the rotating rod 74 rotate synchronously. The connecting gear 75 meshes with the toothed plate 76 fixed to the top of the I-shaped bracket 1. Since the toothed plate 76 is fixed, the connecting gear 75 will roll along the toothed groove of the toothed plate 76 when it rotates, thereby pushing the rotating rod 74 and the sliding plate 4 connected to it to move laterally in the sliding groove 8.

[0039] Specifically, when the adsorbed and fixed sheet material needs to be transported to the layup position, the lateral movement component 7 is activated. The stepper motor 71 is fixed at the top center of the sliding plate 4. After being powered on, the output end of the stepper motor 71 drives the drive bevel gear 72 to rotate. The drive bevel gear 72 meshes with the hollow bevel gear 73, transmitting the rotational motion to the hollow bevel gear 73, which in turn drives the rotating rod 74, which is fixedly connected to the inner wall of the hollow bevel gear 73, to rotate. The connecting gears 75 at the left and right ends of the rotating rod 74 rotate synchronously, and the connecting gears 75 mesh with the toothed plate 76 fixed at the top of the I-shaped bracket 1. Since the toothed plate 76 is fixed, the connecting gear 75 will roll along the toothed groove of the toothed plate 76 when it rotates, thereby pushing the rotating rod 74 and the sliding plate 4 connected to it to move laterally in the slide groove 8. During the movement of the sliding plate 4, the hydraulic rod 6 can adjust the extension length according to actual needs to change the height of the main substrate 5 and the board material to adapt to boards of different thicknesses or meet the height requirements of the layup process. Finally, the sliding plate 4 drives the main substrate 5, the extension adjustment mechanism 2 and the board material that is adsorbed and fixed to move together, accurately delivering the board material to the layup position and completing the automatic layup alignment operation.

[0040] Reference Figure 2 , Figure 3 and Figure 5The bottom of the vacuum suction cup 22 is equipped with an elastic buffer pad made of silicone. The bottom of the elastic buffer pad has anti-slip textures to increase friction during adsorption and prevent damage to the board surface. When the vacuum suction cup 22 adsorbs the board, the elastic buffer pad acts as a cushion, preventing direct rigid contact between the vacuum suction cup 22 and the board surface. The presence of the elastic buffer pad, through its own elastic deformation, evenly disperses the adsorption force applied by the vacuum suction cup 22, protecting the integrity of the board surface and ensuring that the board is not physically damaged during adsorption. The anti-slip texture design increases the elasticity and cushioning effect. The friction between the pad and the sheet surface can effectively prevent the sheet from sliding even if it is affected by slight external vibration or airflow, thus ensuring the stability of the sheet in the adsorption state. A pressure sensor is provided on the left side of the baffle 33. The pressure sensor is electrically connected to an external controller. The external controller controls the start and stop of the limit mechanism 3 according to the signal from the pressure sensor. The pressure sensor is used to monitor the pressure value of the sheet during the limit process in real time to prevent excessive compression of the sheet during the limit process. The pressure sensor senses the pressure generated when the sheet comes into contact with the baffle 33 in real time. By electrically connecting the pressure sensor to an external controller, real-time transmission of pressure data can be achieved. After receiving the pressure signal from the pressure sensor, the external controller analyzes and processes the signal. When the pressure exceeds the threshold, it indicates that the sheet material is being squeezed too much and there is a risk of damage. At this time, the external controller will immediately issue a warning to avoid excessive squeezing of the sheet material. Limiting protrusions are provided on both sides of the toothed plate 76, and limiting grooves adapted to the limiting protrusions are opened at the edge of the connecting gear 75. The limiting protrusions and limiting grooves cooperate to enhance the stability of the sliding plate 4 during movement and prevent it from deviating during movement. During the movement of the sliding plate 4 through the lateral moving component 7, the connecting gear 75 rolls along the tooth groove of the toothed plate 76. At this time, the limiting protrusions are embedded in the limiting grooves at the edge of the connecting gear 75 to form a mechanical constraint structure, reducing the occurrence of deviation and ensuring that the sliding plate 4 moves smoothly in the predetermined direction. The limiting protrusions can prevent the connecting gear 75 from moving laterally in the limiting grooves, so that the connecting gear 75 always stays on the correct rolling path.

[0041] Specifically, when the vacuum suction cup 22 adsorbs the sheet material, the elastic buffer pad can play a buffering role, avoiding direct rigid contact between the vacuum suction cup 22 and the sheet material surface. The presence of the elastic buffer pad can evenly disperse the adsorption force applied by the vacuum suction cup 22 through its own elastic deformation, protecting the integrity of the sheet material surface and ensuring that the sheet material is not physically damaged during the adsorption process. The anti-slip texture design can increase the friction between the elastic buffer pad and the sheet material surface. Even if the sheet material is affected by slight external vibrations or airflow, the greater friction can effectively prevent the sheet material from sliding relative to each other, thereby ensuring the stability of the sheet material in the adsorption state. The pressure sensor can detect the pressure generated when the sheet material comes into contact with the baffle 33 in real time. By electrically connecting the pressure sensor to an external controller, real-time transmission of pressure data can be achieved. After receiving the pressure signal from the pressure sensor, the external controller analyzes and processes the signal. When the pressure exceeds a threshold, it indicates that the sheet material is being subjected to excessive compression and is at risk of damage. At this time, the external controller will immediately issue a warning to avoid excessive compression of the sheet material. During the movement of the sliding plate 4 via the lateral moving component 7, the connecting gear 75 rolls along the tooth groove of the toothed plate 76. At this time, the limiting protrusion is embedded in the limiting groove on the edge of the connecting gear 75, forming a mechanical constraint structure to reduce the occurrence of offset and ensure that the sliding plate 4 moves smoothly in the predetermined direction. The limiting protrusion can prevent the connecting gear 75 from laterally moving within the limiting groove, so that the connecting gear 75 always stays on the correct rolling path.

[0042] Working principle: First, the I-shaped bracket 1 serves as the support frame of the equipment. The sliding plate 4 is connected to the main base plate 5 via hydraulic rods 6 on its left and right sides. Before startup, the hydraulic rods 6 are in an initial retracted state, maintaining a certain distance between the sliding plate 4 and the main base plate 5. At this time, the sliding grooves 8 on the adjacent sides of the two I-shaped brackets 1 cooperate with the left and right sides of the sliding plate 4 to guide the lateral movement of the sliding plate 4. The conveyor belt is placed at the bottom of the I-shaped bracket 1, and the sheet material is fed from the left side to directly below the device. At this time, the hydraulic rods 6 are activated, causing the main base plate 5 to fall and adhere to the sheet material. Subsequently, the vacuum device 28 is activated. The vacuum device 28, through the telescopic tube 29, connecting tube 23, and corrugated tube 24, creates negative pressure inside all the vacuum suction cups 22. Multiple suction cups distributed between the telescopic plate 21 and the main base plate 5... The vacuum suction cup 22 at the bottom firmly adsorbs and fixes the board material to ensure that the board material will not shift during subsequent operations. For boards of different specifications, the servo motor 272 is powered on and started, and its output end drives the drive gear 273 to rotate. Since the drive gear 273 meshes with the telescopic racks 274 on the front and rear sides, the rotation of the drive gear 273 will cause the telescopic racks 274 on both sides to slide along the inner wall of the U-shaped support plate 271 to the sides or the middle. One end of the telescopic rack 274 is fixedly connected to the telescopic plate 21, thereby driving the telescopic plate 21 to extend and retract synchronously on the left and right sides of the main base plate 5, adjusting the overall width to adapt to the board material size. At the same time, the limiting rod 25 cooperates with the limiting hole 26 to guide and limit the telescopic plate 21 during the extension and retraction process, ensuring that the telescopic plate 21 moves smoothly and is positioned accurately.

[0043] Furthermore, through the limiting mechanism 3, for different specifications of sheet materials, by rotating the rotating block 35, since the rotating block 35 is fixedly connected to the screw 34, and the screw 34 is threadedly connected to the middle of the fixed plate 31, the rotation of the rotating block 35 will cause the screw 34 to move axially. The baffle 33, which is rotatably connected to the left end of the screw 34, will slide on the front and rear sides of the inner wall of the fixed plate 31 under the push of the screw 34 and with the help of the limiting rod 32 fixedly connected to it. The sliding connection between the limiting rod 32 and the fixed plate 31 ensures the stability and straightness of the movement of the baffle 33, thereby limiting the position of the sheet material above the conveying device. When the sheet material is conveyed to the designated position, the baffle 33 will block the sheet material at the preset layup start position. By mechanically limiting, the sheet material is ensured to be in a precise position, providing a guarantee for subsequent precise alignment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
