Description

Technical Field

[0001] This invention relates to the field of automotive soundproofing composite panel technology, specifically to a multi-layer synchronous composite device for automotive soundproofing composite panels. Background Technology

[0002] Multi-layer composite of automotive sound-absorbing sheet composite panels refers to the process of tightly bonding two or more thin-layer materials with different physical, chemical and acoustic properties together through specific processes, such as adhesive bonding, to form a new type of sheet material with comprehensive performance that cannot be matched by a single material. In automotive NVH noise, vibration and acoustic roughness engineering, this multi-layer composite structure is one of the core technologies for solving in-vehicle noise.

[0003] Traditional automotive muffler composite panel multilayer lamination equipment typically uses a layer-by-layer lamination method. That is, the first layer of material is laminated with the second layer of material, and after that, the laminated double layer of material is laminated with the third layer of material, and so on. This method cannot achieve the effect of multilayer synchronous lamination, which makes the adhesive layers prone to uneven heating. At the same time, some areas are over-cured and some are under-cured, resulting in uneven bonding strength. It also causes problems such as low production efficiency, high energy consumption, and high scrap rate. Summary of the Invention

A placement platform is provided above the fixed frame. Four limiting side plates and two limiting baffles are fixedly connected to the upper surface of the placement platform. A second servo motor is fixedly connected to the outer surface of the support frame. A bidirectional screw is fixedly connected to the output end of the second servo motor. Both ends of the bidirectional screw are rotatably connected to the inner wall of the support frame. Two placement frames are threadedly connected to the outer surface of the bidirectional screw. The outer surface of each placement frame is slidably connected to the inner wall of the limiting side plate. Four multi-stage electric push rods are fixedly connected to the inner top wall of the support frame. A pressure plate is fixedly connected to the telescopic ends of the four multi-stage electric push rods.

[0007] Preferably, a support base is fixedly connected to one side of the fixed frame near the first servo motor, and the upper surface of the support base is fixedly connected to the bottom surface of the first servo motor.

[0008] Preferably, each of the two placement racks has two guide posts fixedly connected to its opposite side, and the outer surface of each guide post is slidably connected to the inner wall of the rack.

[0009] Preferably, a plurality of pulleys are fixedly connected to the outer surfaces of several conveying rollers, and a synchronous belt is rotatably connected to the outer surface of each group of pulleys.

[0010] Preferably, the adhesive application mechanism includes a movable plate, an L-shaped groove is provided on the upper surface of the fixed frame, the outer surface of the movable plate is slidably connected to the inner wall of the L-shaped groove, a multi-port pipe is fixedly connected to the inner wall of the movable plate, a lifting frame is provided on the outer side of the multi-port pipe, and a number of sealing posts are fixedly connected to the bottom surface of the lifting frame, with the outer surface of each sealing post slidably connected to the inner wall of the multi-port pipe.

[0011] Preferably, the bottom surface of the lifting frame is fixedly connected with six springs, and the bottom end of each spring is fixedly connected to the upper surface of the moving plate.

[0012] Preferably, the bottom surface of the fixed frame is fixedly connected to two support legs, and the upper surface of each support leg has two mounting holes.

[0013] Preferably, a curing box is fixedly connected to the upper surface of the fixed frame, and a controller is fixedly connected to the outer surface of the curing box.

[0014] Preferably, a handle is fixedly connected to the side of the lifting frame away from the moving plate, and an anti-slip pad is fixedly connected to the outer surface of the handle.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: Firstly, this invention, through the provision of a synchronous composite mechanism, utilizes a first servo motor to drive one of the conveyor rollers to rotate. This conveyor roller, through the cooperation of a pulley fixedly connected to its outer surface and a synchronous belt, drives the remaining conveyor rollers to rotate synchronously, thereby achieving stable conveying of the composite panels. Simultaneously, the operation of a second servo motor drives a bidirectional screw to rotate, causing two placement frames to move closer or further apart along the inner wall of the limiting side plate under the action of the bidirectional screw's thread. When the placement frames are close together, they can support the composite panels, facilitating the simultaneous placement of multiple layers of panels. The limiting side plate and limiting baffle effectively prevent the panels from shifting during placement and conveying, ensuring the alignment accuracy of the multiple layers. When the placement frames are far apart, the completed composite panels can be automatically stacked together, and then a multi-stage electric push rod drives the pressure plate to descend, applying uniform and stable pressure to the multiple layers of panels, achieving synchronous composite of multiple layers. This effectively avoids the problem of uneven curing of adhesive layers caused by traditional layer-by-layer composite methods, achieving synchronous composite of multiple layers of panels, greatly improving the bonding strength and overall quality of the composite panels, and significantly increasing production efficiency.

[0016] Secondly, this invention, by incorporating an adhesive application mechanism, utilizes an L-shaped chute to guide the moving plate smoothly along its inner wall. This allows the adhesive application mechanism to flexibly adjust the application position. The multi-port pipe can be connected to an external adhesive supply device to evenly distribute the adhesive to each outlet. Under the elastic action of the spring, the lifting frame drives the sealing column to tightly adhere to the inner wall of the multi-port pipe, effectively sealing the outlets and preventing adhesive leakage and waste during non-working periods. By lifting the lifting frame upwards with the handle, the spring is stretched, causing the sealing column to move upwards, opening the outlets, and allowing the adhesive to flow out from the multi-port pipe. As the moving plate moves along the L-shaped chute, synchronous adhesive application to the surface of the multi-layer board is completed, further ensuring the uniformity and precision of the adhesive application. This provides a reliable quality foundation for subsequent multi-layer synchronous lamination, enabling synchronous adhesive application, lamination, and curing. Attached Figure Description

[0019] 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.

[0020] Example 1

[0021] Please see Figure 1-9The system includes a fixed frame 1, a synchronous laminating mechanism 2 above the fixed frame 1, and an adhesive applicator 3 above the fixed frame 1. The synchronous laminating mechanism 2 includes a support frame 201, the outer surface of which is fixedly connected to the outer surface of the fixed frame 1. Several stabilizing blocks 202 are fixedly connected to the upper surface of the support frame 201. A conveying roller 203 is rotatably connected to the inner wall of each set of stabilizing blocks 202. A first servo motor 204 is fixedly connected to the end of one of the conveying rollers 203 away from the fixed frame 1. Several limiting frames 205 are fixedly connected to the inner wall of the fixed frame 1. Several limiting rollers 210 are rotatably connected to the inner wall of each limiting frame 205. A placement platform 207 is provided above the fixed frame 1. Several limiting rollers 210 are fixedly connected to the upper surface of the placement platform 207. The support frame 201 has four limiting side plates 217 and two limiting baffles 218. A second servo motor 213 is fixedly connected to the outer surface of the support frame 201. A bidirectional screw 214 is fixedly connected to the output end of the second servo motor 213. Both ends of the bidirectional screw 214 are rotatably connected to the inner wall of the support frame 201. Two placement racks 215 are threadedly connected to the outer surface of the bidirectional screw 214. The outer surface of each placement rack 215 is slidably connected to the inner wall of the limiting side plates 217. Four multi-stage electric push rods 211 are fixedly connected to the inner top wall of the support frame 201. The telescopic ends of the four multi-stage electric push rods 211 are fixedly connected to a pressure plate 212. By setting the synchronous composite mechanism 2, multiple composite materials can be composited synchronously to improve the efficiency and stability of synchronous composite.

[0022] A support base 206 is fixedly connected to one side of the fixed frame 1 near the first servo motor 204. The upper surface of the support base 206 is fixedly connected to the bottom surface of the first servo motor 204. The support base 206 can provide stable support for the first servo motor 204, preventing it from shifting or tilting due to vibration during operation, ensuring the stability and reliability of the output power of the first servo motor 204, and thus ensuring the rotation accuracy and synchronization of the conveyor roller 203.

[0023] Two guide posts 216 are fixedly connected to the opposite sides of the two placement racks 215. The outer surface of each guide post 216 is slidably connected to the inner wall of the support frame 201. The guide posts 216 can guide and limit the placement rack 215 when it moves along the bidirectional screw 214, effectively preventing the placement rack 215 from rotating or deviating during the movement, ensuring that the placement rack 215 always moves smoothly along a straight line, and further improving the stability and positional accuracy of the placement rack 215 in supporting the multi-layer board.

[0024] Several conveying rollers 203 are fixedly connected to several pulleys 208 on their outer surfaces. Each set of pulleys 208 is rotatably connected to a synchronous belt 209 on its outer surface. Through the transmission cooperation between the pulleys 208 and the synchronous belt 209, when the first servo motor 204 drives one of the conveying rollers 203 to rotate, it can drive all the conveying rollers 203 to rotate synchronously with the same speed and direction. This ensures that the composite board can move forward smoothly and at a uniform speed during the conveying process, avoiding the board conveying deviation or jamming caused by the inconsistent speed of each conveying roller 203. This ensures the conveying stability and positional consistency of the multilayer board before synchronous composite.

[0025] The specific implementation method of this embodiment is as follows: In use, the first servo motor 204, the second servo motor 213, and the multi-stage electric push rod 211 are first connected to an external power supply. When it is necessary to perform multi-layer composite bonding of automotive muffler composite panels, the substrate is first placed on the surface of the placement platform 207, and the position of the substrate is limited by the limiting side plate 217 and the limiting baffle 218 to prevent the substrate from shifting in subsequent operations. Then, the composite panels are placed on each layer surface of the placement rack 215 for support. The placement rack 215 can ensure that there is a certain space between each layer of composite panels to facilitate the glue application work. Next, the adhesive is applied. After the adhesive is applied, the second servo motor 213 is turned on, driving the bidirectional screw 214 to rotate. Since the outer surface of the bidirectional screw 214 is threaded with two placement brackets 215, and the outer surface of the placement brackets 215 is slidably connected to the inner wall of the limiting side plate 217, while the guide post 216 fixedly connected to the opposite side of the placement brackets 215 is slidably connected to the inner wall of the support frame 201, under the rotation of the bidirectional screw 214, the two placement brackets 215 will move away from each other along the inner wall of the limiting side plate 217. As the placement brackets 215 move, the multi-layered support on their surfaces... The composite board loses its support and, under the limiting action of the limiting side plate 217 and the limiting baffle 218, gradually overlaps on top of the substrate, achieving initial alignment of the multi-layer boards. After the multi-layer boards are stacked, four multi-stage electric push rods 211 are activated. The telescopic ends of the multi-stage electric push rods 211 drive the pressure plate 212 to slowly descend. After the pressure plate 212 contacts the uppermost composite board, it continues to apply stable pressure, causing the multi-layer boards to fit tightly together under pressure, completing the synchronous composite process. Subsequently, the first servo motor 204 is started, driving the conveyor roller 203 fixedly connected to it to rotate. The conveyor roller 203 passes through its outer surface... The fixed pulley 208 and the synchronous belt 209 work together to drive all the other conveyor rollers 203 to rotate synchronously. The conveyor rollers 203 contact the composite board on the placement platform 207 and convey the composite board forward so that it enters the subsequent curing box 6 for curing treatment, thereby completing the entire multi-layer synchronous composite production process. During the movement, the limiting frame 205 and the limiting roller 210 can effectively limit the two sides of the board to prevent the board from shifting laterally due to inertia or external force during the conveying process. At the same time, they can also reduce the friction between the board and the inner wall of the fixed frame 1 and ensure the smooth conveying of the board.

[0026] Example 2

[0027] Please see Figure 1-9The glue application mechanism 3 includes a movable plate 301. An L-shaped groove 303 is provided on the upper surface of the fixed frame 1. The outer surface of the movable plate 301 is slidably connected to the inner wall of the L-shaped groove 303. A multi-port pipe 302 is fixedly connected to the inner wall of the movable plate 301. A lifting frame 305 is provided on the outer side of the multi-port pipe 302. Several sealing columns 306 are fixedly connected to the bottom surface of the lifting frame 305. The outer surface of each sealing column 306 is slidably connected to the inner wall of the multi-port pipe 302. By setting up the glue application mechanism 3, glue application can be carried out synchronously, ensuring the uniformity and accuracy of glue application.

[0028] The bottom surface of the lifting frame 305 is fixedly connected with six springs 304. The bottom end of each spring 304 is fixedly connected to the upper surface of the moving plate 301. The springs 304 can provide a continuous downward pulling force to the lifting frame 305, so that the sealing column 306 always fits tightly against the inner wall of the multi-port pipe 302 when not coated with glue, thereby reliably sealing the glue outlet and effectively preventing glue from dripping when not in use, avoiding glue waste and pollution to equipment and working environment.

[0029] The bottom surface of the fixed frame 1 is fixedly connected to two support legs 4. Each support leg 4 has two mounting holes 5 on its upper surface. The support legs 4 can be fixedly connected to the ground or workbench through the mounting holes 5 with bolts, providing a stable support foundation for the entire equipment, effectively dispersing the vibration generated during equipment operation, avoiding the equipment from shaking and affecting the composite accuracy and glue application effect, while improving the overall structural stability and safety of the equipment.

[0030] A curing chamber 6 is fixedly connected to the upper surface of the fixed frame 1, and a controller 7 is fixedly connected to the outer surface of the curing chamber 6. The curing chamber 6 can provide a suitable curing environment for the composite board. The controller 7 can precisely control the temperature and curing time inside the curing chamber 6 to ensure that the adhesive layer in the composite board is fully cured, further improving the bonding strength and structural stability of the composite board, realizing an integrated production process from gluing, lamination to curing, and effectively shortening the production cycle.

[0031] A handle 8 is fixedly connected to the side of the lifting frame 305 away from the moving plate 301. An anti-slip pad 9 is fixedly connected to the outer surface of the handle 8. The handle 8 provides a convenient grip for the operator, making it easy to manually control the lifting operation of the lifting frame 305. The anti-slip pad 9 can effectively increase the friction between the hand and the handle 8, preventing the lifting frame 305 from going out of control due to slipping during operation, and ensuring the safety and stability of the glue application operation.

[0032] The specific implementation method of this embodiment is as follows: In use, firstly, the flange interface at one end of the multi-port pipe 302 is connected to an external glue supply device to ensure that the glue can be stably delivered to the inside of the multi-port pipe 302. When it is necessary to apply glue to the multi-layer composite board placed on the placement rack 215, the operator holds the handle 8 with anti-slip pad 9 and, in conjunction with the transverse groove of the L-shaped slide 303, pushes the moving plate 301 and the multi-port pipe 302 into the pre-reserved gap between multiple composite boards until the moving plate 301 is in place. Then, the operator pulls the moving plate 301 to move in the longitudinal groove of the L-shaped slide 303. At the same time, the operator pushes the handle 8 upward, causing the lifting frame 305 to move upward against the tension of the spring 304. At this time, the sealing column 306 fixedly connected to the bottom of the lifting frame 305 moves upward, causing its bottom to separate from the glue outlet on the inner wall of the multi-port pipe 302. The glue flows out evenly from each glue outlet of the multi-port pipe 302 and drips onto the corresponding layer of composite board. On the material surface, the operator keeps the handle 8 raised and slowly pushes the moving plate 301 along the longitudinal groove of the L-shaped slide 303 at a uniform speed. During this process, the glue outlet on the multi-port pipe 302 continuously applies glue to the surfaces that need to be bonded between the multi-layer composite boards, so that the contact surfaces between each two layers of composite boards can be coated with glue at the same time. When the glue application is completed, the operator releases the handle 8, and the lifting frame 305 moves down quickly under the elastic reset action of the spring 304, driving the sealing column 306 to re-close tightly against the inner wall of the multi-port pipe 302, completely sealing the glue outlet and stopping the glue flow. Then the moving plate 301 is pulled back to the initial position along the transverse groove of the L-shaped slide 303 to perform the next glue application operation or to avoid affecting the subsequent composite process. In this way, the glue application mechanism 3 can efficiently and accurately complete the synchronous glue application of multi-layer boards, providing a good bonding foundation for subsequent synchronous composite.

[0033] The working principle of this invention is as follows: In use, firstly, the first servo motor 204, the second servo motor 213, and the multi-stage electric push rod 211 are connected to an external power source. The flange interface at one end of the multi-port pipe 302 is then connected to an external glue supply device to ensure stable glue delivery into the multi-port pipe 302. When multi-layer lamination of automotive sound-absorbing sheet composite panels is required, the substrate is first placed on the surface of the placement platform 207, and its position is limited by the limiting side plate 217 and the limiting baffle 218 to prevent displacement during subsequent operations. Then, the composite panels are sequentially placed onto each layer of the placement rack 215 for support. The placement rack 215 ensures sufficient space between each layer of composite panels for easy glue application. When applying adhesive to the multi-layer composite panels placed on the rack 215, the operator holds the handle 8 with the anti-slip pad 9 and, in conjunction with the transverse groove of the L-shaped slide 303, pushes the moving plate 301 and the multi-port pipe 302 into the pre-reserved gaps between the multiple composite panels until the moving plate 301 is in place. Then, the operator pulls the moving plate 301 along the longitudinal groove of the L-shaped slide 303 while simultaneously pushing the handle 8 upwards. This causes the lifting frame 305 to move upwards against the tension of the spring 304. At this time, the sealing column 306, fixedly connected to the bottom of the lifting frame 305, moves upwards, separating its bottom from the adhesive outlet on the inner wall of the multi-port pipe 302. Adhesive flows evenly from each outlet of the multi-port pipe 302, dripping onto the surface of the corresponding layer of composite panels. The operator maintains... Raise handle 8 upwards and slowly push moving plate 301 along the longitudinal groove of L-shaped slide 303 at a uniform speed. During this process, the glue outlet on multi-channel pipe 302 continuously applies glue to the surfaces that need to be bonded between the multi-layer composite boards, ensuring that the contact surfaces between each two layers of composite boards can be coated simultaneously. After the glue application is completed, the operator releases handle 8, and lifting frame 305 quickly moves downwards under the elastic reset action of spring 304, causing sealing column 306 to re-adhere tightly to the inner wall of multi-channel pipe 302, completely sealing the glue outlet and stopping the glue flow. Then, moving plate 301 is pulled back to its initial position along the transverse groove of L-shaped slide 303 to allow for the next glue application operation or to avoid affecting subsequent composite processes. The adhesive application mechanism 3 can efficiently and accurately complete the synchronous adhesive application of multi-layer boards, providing a good bonding foundation for subsequent synchronous lamination. After adhesive application, the second servo motor 213 is activated, driving the bidirectional screw 214 to rotate. Since the outer surface of the bidirectional screw 214 is threaded with two placement frames 215, and the outer surface of the placement frames 215 is slidably connected to the inner wall of the limiting side plate 217, and the guide post 216 fixedly connected to the opposite side of the placement frames 215 is slidably connected to the inner wall of the support frame 201, under the rotation of the bidirectional screw 214, the two placement frames 215 will move away from each other along the inner wall of the limiting side plate 217. As the placement frames 215 move, the multi-layer composite board supported on their surface loses support.Under the limiting action of the limiting side plate 217 and the limiting baffle 218, the multi-layer boards will gradually overlap on the substrate, achieving initial alignment and placement. After the multi-layer boards are stacked, four multi-stage electric push rods 211 are activated. The telescopic ends of the multi-stage electric push rods 211 drive the pressure plate 212 to slowly descend. After the pressure plate 212 contacts the uppermost composite board, it continues to apply stable pressure, so that the multi-layer boards are tightly bonded under pressure, completing the synchronous composite process. Subsequently, the first servo motor 204 is started, driving the conveyor roller 203 fixedly connected to it to rotate. The conveyor roller 203 is fixedly connected to its outer surface. The pulley 208 and the synchronous belt 209 work together to drive all the other conveyor rollers 203 to rotate synchronously. The conveyor rollers 203 contact the composite board on the placement platform 207, conveying the composite board forward so that it enters the subsequent curing box 6 for curing treatment, thus completing the entire multi-layer synchronous composite production process. During the movement, the limiting frame 205 and the limiting rollers 210 can effectively limit the sides of the board, preventing the board from shifting laterally due to inertia or external force during the conveying process. At the same time, they can also reduce the friction between the board and the inner wall of the fixed frame 1, ensuring the smooth conveying of the board.
