Description

Technical Field

[0001] This utility model relates to a flexible material bonding device, belonging to the field of flexible material bonding technology. Background Technology

[0002] Flexible material lamination is a key process in modern industrial production, widely used in packaging, electronics, medical devices, new energy, and many other fields. Its lamination precision and stability directly determine the appearance quality, structural strength, and functional reliability of downstream products. For example, in the packaging industry, the lamination of film and paper requires a smooth, bubble-free interface to meet the sealing and display requirements of product packaging. In the electronics industry, the lamination of flexible printed circuit boards (FPCs) and protective films requires strict control of lamination deviations to avoid short circuits, signal interference, and other problems caused by lamination defects, which could affect the normal operation of electronic equipment. As downstream industries increasingly demand more refined and high-performance products, existing flexible material laminating equipment is gradually revealing its technological limitations. Currently, mainstream laminating equipment only has the function of layer-by-layer lamination along the X-axis (i.e., the material conveying direction), and its tension control system on the feeding shaft can only provide tension adjustment in a single dimension in the X-axis. However, flexible materials generally have high tensile properties. When relying solely on X-axis tension constraints during the lamination process, there is a lack of effective tension support and control in the Y-axis direction (i.e., the material width direction). This can easily lead to appearance defects such as wrinkles and wavy lines due to uneven stress in different areas of the material. Such defects not only seriously affect the visual effect of the product, but may also cause gaps at the lamination interface, reducing the overall performance of the composite material (such as the barrier properties of packaging and the insulation properties of circuit boards). In summary, the lack of multi-dimensional tension control capabilities in existing flexible material bonding equipment can no longer meet the requirements of current industrial production for bonding quality, material utilization, and production stability. There is an urgent need for a new bonding device that can achieve multi-directional tension coordinated control and effectively avoid material wrinkling to solve the pain points of existing technologies.

[0015] 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.

[0016] Please see Figure 1-6 The present invention provides a technical solution: a flexible material bonding device, including a machine base 1, a U-shaped frame 2 vertically installed on the top of the machine base 1, a first guide plate 11 horizontally installed inside the U-shaped frame 2, and a second guide plate 12 horizontally installed inside the U-shaped frame 2 at a position directly below the first guide plate 11, and leveling components are provided at the top of the first guide plate 11 and the bottom of the second guide plate 12. The outer wall of the U-shaped frame 2 is provided with unfolding components near the first guide plate 11 and the second guide plate 12. The top of the machine base 1 is symmetrically installed with mounting plates 22 along the vertical direction, and the mounting plates 22 are provided with conveying and bonding components. The leveling assembly includes a first lifting plate 3, a plastic push plate 4, and a first spring 5. The first lifting plate 3 is located directly above the first guide plate 11 inside the U-shaped frame 2, and the second lifting plate 13 is located directly below the second guide plate 12 inside the U-shaped frame 2. Plastic push plates 4 are rotatably installed at both ends of the bottom of the first lifting plate 3 and both ends of the top of the second lifting plate 13 in an inclined direction. The first spring 5 is installed vertically at both ends of the bottom of the first lifting plate 3 and both ends of the top of the second lifting plate 13, and the ends of the first spring 5 are fixedly connected to the outer wall of the plastic push plate 4. In the embodiment of the present utility model, after the device is started, the power system matched with the first lifting plate 3 drives the first driving rod 8 to rotate around its own axis, and the eccentric wheels 9 fixedly sleeved at both ends of the first driving rod 8 rotate synchronously with the first driving rod 8. When the protruding end of the eccentric wheel 9 comes into contact with the top of the first lifting plate 3, a vertical downward thrust is applied to the first lifting plate 3, causing the first lifting plate 3 to slide vertically downward along the inner side wall of the square frame 2. In this process, the plastic push plates 4 connected to the two ends of the bottom of the first lifting plate 3 through rotating shafts in an inclined and rotatable manner move downward together, until the bottoms of the plastic push plates 4 come into contact with the surface of the flexible material conveyed on the top of the first guide plate 11. Due to the reaction force of the material on the plastic push plates 4, the plastic push plates 4 will rotate around the rotating shafts, and simultaneously compress the first springs 5, one end of which is fixed to the bottom of the first lifting plate 3 and the other end of which is fixed to the outer wall of the plastic push plates 4. As the first lifting plate 3 continues to move downward, the rotation angle of the two plastic push plates 4 gradually increases, and finally they spread outward in a "figure-eight" shape, completing the stretching action in the width direction of the material. Similarly, the plastic push plates 4 mounted on the top of the second lifting plate 13 can perform a stretching action in the width direction on the flexible material passing through the bottom of the second guide plate 12; The active tension regulation of the "Y-axis" in the width direction of the flexible material is realized, which effectively eliminates defects such as wrinkles and wavy patterns caused by uneven Y-direction stress on the material, and provides a flat material base for the subsequent laminating process. The elastic buffering effect of the first spring 5 can prevent the plastic push plates 4 from applying excessive pressure to the material, prevent flexible materials such as films and flexible circuit boards from being damaged by extrusion, and at the same time adapt to flexible materials of different thicknesses, improving the universality of the device; Please refer to Figure 3 , further, first guide rods 6 are vertically installed at both ends of the top of the first lifting plate 3, the tops of the first guide rods 6 slidably penetrate through the inner top of the square frame 2, limit blocks are installed at the ends of the first guide rods 6 that penetrate through the square frame 2, second springs 7 are further sleeved on the ends of the first guide rods 6 that penetrate through the square frame 2, and the second springs 7 are located between the top of the square frame 2 and the limit blocks; In an embodiment of this utility model, when the first lifting plate 3 is pushed downward by the eccentric wheel 9, the first guide rod 6, which is vertically fixed at both ends of its top, will slide vertically downward synchronously along the guide hole preset at the top of the U-shaped frame 2, ensuring that the first lifting plate 3 only moves in the vertical direction and does not deviate horizontally. At this time, a limit block is installed at the end of the first guide rod 6 that passes through the top of the U-shaped frame 2, and the second spring 7 sleeved on the outside of the first guide rod 6 will be compressed by the limit block, converting kinetic energy into elastic potential energy for storage. When the protruding end of the eccentric wheel 9 rotates to disengage from the top of the first lifting plate 3, the downward thrust on the first lifting plate 3 disappears, the second spring 7 releases the stored elastic potential energy, and generates an upward elastic force on the limit block, pulling the first guide rod 6 to slide vertically upward along the guide hole, thereby driving the first lifting plate 3 back to the initial position and completing one up-and-down movement. This process is repeated cyclically with the continuous rotation of the eccentric wheel 9. The guiding function of the first guide rod 6 can strictly limit the movement trajectory of the first lifting plate 3, prevent it from shifting horizontally during up and down movement, ensure the accurate leveling position of the plastic push plate 4 on the material, and improve the stability of the leveling effect; the second spring 7 can realize the automatic reset of the first lifting plate 3 without an additional power source, simplifying the transmission structure of the device while ensuring the continuity of the movement of the first lifting plate 3, matching the leveling action with the material conveying rhythm, and improving production efficiency.

[0017] Please see Figure 3 Furthermore, multiple reset springs 15 are vertically installed at both ends of the bottom of the second lifting plate 13. The bottom of each reset spring 15 is fixedly connected to the inner bottom of the U-shaped frame 2. Multiple second guide rods 14 are also vertically installed at both ends of the bottom of the second lifting plate 13, and the bottom of each second guide rod 14 slides through the inner bottom of the U-shaped frame 2. In this embodiment of the present invention, when the second drive rod 16 is driven by the power system to rotate around its own axis, the eccentric wheels 9 fixedly sleeved at both ends of the second drive rod 16 rotate synchronously with the second drive rod 16. When the protruding end of the eccentric wheel 9 contacts the bottom of the second lifting plate 13, it will apply a vertically upward thrust to the second lifting plate 13, causing the second lifting plate 13 to slide vertically upward along the inner sidewall of the U-shaped frame 2. During this process, the second guide rods 14, which are vertically fixed at both ends of the bottom of the second lifting plate 13, will synchronously move vertically along the guide holes preset at the bottom of the U-shaped frame 2. Slide upwards; at the same time, the reset spring 15 connecting the bottom ends of the second lifting plate 13 and the bottom of the U-shaped frame 2 is stretched, storing elastic potential energy; when the protruding end of the eccentric wheel 9 rotates to disengage from the bottom of the second lifting plate 13, the upward thrust on the second lifting plate 13 disappears, the reset spring 15 releases elastic potential energy, and generates a vertical downward pulling force on the second lifting plate 13, pulling the second lifting plate 13 to slide vertically downward along the inner wall, and the second guide rod 14 slides down to the initial position, completing the reset of the second lifting plate 13, forming a cyclic lifting action; The second guide rod 14 ensures that the second lifting plate 13 moves only in the vertical direction, preventing it from deviating and causing a leveling position deviation of the material at the bottom of the second guide plate 12. The reset spring 15 realizes the automatic reset of the second lifting plate 13, and works with the second drive rod 16 and the eccentric wheel 9 to form a stable transmission cycle. The tension of the reset spring 15 can be adjusted by replacing springs with different elastic coefficients to adapt to flexible materials of different thicknesses and hardnesses, thus avoiding material damage. At the same time, the lifting action of the second lifting plate 13 can be coordinated with the first lifting plate 3 to level the material at the top of the first guide plate 11 and the bottom of the second guide plate 12, respectively, improving the device's pre-processing capability for multi-layer materials.

[0018] Please see Figure 3 Furthermore, a first drive rod 8 is installed horizontally in the U-shaped frame 2, located directly above the first lifting plate 3. Both ends of the first drive rod 8 are fixedly fitted with eccentric wheels 9, which are used to push the first lifting plate 3 to move vertically up and down. A second drive rod 16 is installed horizontally in the U-shaped frame 2, located directly below the second lifting plate 13. Both ends of the second drive rod 16 are fixedly fitted with eccentric wheels 9, which are used to push the second lifting plate 13 to move vertically up and down. In this embodiment of the invention, the device is equipped with a first motor 10, which is driven by a chain. For example, the first sprocket 17 and the second sprocket 18 are connected to the first drive rod 8 and the second drive rod 16 respectively with the chain to achieve synchronous power transmission. When the first motor 10 starts, its output shaft drives the drive sprocket to rotate, which drives the sprocket at the end of the first drive rod 8 and the sprocket at the end of the second drive rod 16 to rotate synchronously through the chain, thereby driving the first drive rod 8 and the second drive rod 16 to rotate synchronously in the horizontal direction. The eccentric wheels 9 fixedly sleeved at both ends of the first drive rod 8 rotate with the first drive rod 8 and periodically apply a downward thrust to the first lifting plate 3. The eccentric wheels 9 fixedly sleeved at both ends of the second drive rod 16 rotate with the second drive rod 16 and periodically apply an upward thrust to the second lifting plate 13. Since the first drive rod 8 and the second drive rod 16 rotate in the same direction and at the same speed, the pushing rhythm of the eccentric wheels 9 on the lifting plates on the two drive rods is completely synchronized, ensuring that when the first lifting plate 3 moves downward, the second lifting plate 13 moves upward synchronously, forming a coordinated leveling action. The synchronous transmission of the first drive rod 8 and the second drive rod 16 enables the first lifting plate 3 and the second lifting plate 13 to move in coordination, which can simultaneously level the two layers of material and improve pretreatment efficiency; the periodic pushing of the eccentric wheel 9 can realize the reciprocating motion of the lifting plate without the need for an additional reversing mechanism, simplifying the device structure and reducing maintenance costs.

[0019] Please see Figure 4Furthermore, the leveling assembly also includes rubber positive and negative threaded rods 21. The rubber positive and negative threaded rods 21 are installed horizontally on the outer side of the U-shaped frame 2 at the top of the first guide plate 11 and the bottom of the second guide plate 12. The rubber positive and negative threaded rods 21 are used to level the material during the conveying process. In this embodiment of the invention, the rubber threaded rod 21 is horizontally mounted on the outside of the U-shaped frame 2 via bearings, corresponding to the top of the first guide plate 11 and the bottom of the second guide plate 12 respectively; a fourth sprocket 20 is fixedly sleeved on one end of the rubber threaded rod 21, and the fourth sprocket 20 is connected to the third sprocket 19 at the end of the first drive rod 8 or the third sprocket 19 at the end of the second drive rod 16 via a chain to achieve power transmission; when the first drive rod 8 or the second drive rod 16 rotates, power is transmitted through the third sprocket 19 and the chain. The fourth sprocket 20 rotates synchronously, thereby driving the rubber positive and negative threaded rod 21 to rotate along its own axis. Since the rubber positive and negative threaded rod 21 has leveling grooves that contact the material, when the rubber positive and negative threaded rod 21 rotates, the leveling grooves on the two threads will separate along the axial direction of the rod and apply outward pulling force to both sides of the material width direction. During the material conveying process, the rubber positive and negative threaded rod 21 rotates continuously and is always in contact with the material surface, performing continuous leveling treatment on the material in real time, forming a double leveling with the plastic push plate 4. The rubber positive and negative thread rod 21 is made of rubber, which can avoid scratching the material surface when in contact with the material and protect the integrity of the material; the positive and negative thread design realizes uniform stretching in the width direction of the material, further eliminating local wrinkles. Compared with the flattening of a single plastic push plate, the flatness of the material is greatly improved.

[0020] Please see Figure 1 Furthermore, a first sprocket 17 is installed at the end of the first drive rod 8. The first sprocket 17 is connected to the second sprocket 18 via a chain. The second sprocket 18 is fixedly installed at the end of the second drive rod 16. A third sprocket 19 is also installed at the ends of both the first drive rod 8 and the second drive rod 16. Both third sprockets 19 are connected to two fourth sprockets 20 via chains. The two fourth sprockets 20 are fixedly installed at the ends of the two rubber positive and negative threaded rods 21, respectively. In this embodiment of the invention, the first motor 10 serves as the single power source for the entire system. Its output shaft drives the active sprocket to rotate via a chain. The active sprocket is connected to the sprocket at the end of the first drive rod 8 via a chain. Simultaneously, the first sprocket 17 installed at the end of the first drive rod 8 is connected to the second sprocket 18 installed at the end of the second drive rod 16 via a chain, thereby achieving synchronous rotation of the first drive rod 8 and the second drive rod 16. In addition, a third sprocket 19 is also installed at the end of the first drive rod 8. This third sprocket 19 is connected to the fourth sprocket 20 of the corresponding rubber threaded rod 21 at the top of the first guide plate 11 via a chain. Similarly, a third sprocket 19 is installed at the end of the second drive rod 16. This third sprocket 19 is connected to the fourth sprocket 20 of the corresponding rubber threaded rod 21 at the bottom of the second guide plate 12 via a chain. Ultimately, a synchronous transmission path is formed for the entire system, in which the first motor 10 drives the first drive rod 8, the second drive rod 16, and the rubber positive and negative threaded rod 21. A single power source drives the entire system, avoiding the debugging difficulties of multi-motor coordination and reducing equipment manufacturing costs. The stability of chain drive ensures consistent speed of each component, small action delay, improved leveling and bonding accuracy, clear transmission path, fewer fault points, and quick problem location during later maintenance, reducing equipment downtime.

[0021] Please see Figure 5 Furthermore, the conveying and bonding assembly includes a rubber extrusion roller 23, a gear 24, and a second motor 25. The rubber extrusion roller 23 is rotatably mounted between two mounting plates 22 in a symmetrical direction. The ends of the two rubber extrusion rollers 23 are each equipped with the same type of gear 24, and the two gears 24 mesh with each other. The second motor 25 is fixedly mounted on the outer wall of the mounting plate 22, and the output end of the second motor 25 is connected to the end of one of the rubber extrusion rollers 23 for driving the rubber extrusion roller 23 to rotate. In this embodiment of the invention, two rubber extrusion rollers 23 are rotatably mounted on the top of the machine base 1 between vertically symmetrical mounting plates 22 via bearings. The ends of both rubber extrusion rollers 23 are equipped with the same type of gear 24, which mesh with each other. A second motor 25 is fixedly mounted on the outer wall of the mounting plate 22, and the output end of the second motor 25 is connected to the end of one of the rubber extrusion rollers 23 via a coupling. When the second motor 25 starts, it drives the connected rubber extrusion roller 23 to rotate. The gear 24 at the end of the rubber extrusion roller 23 drives the gear 24 at the end of the other rubber extrusion roller 23 to rotate in the opposite direction, causing the two rubber extrusion rollers 23 to rotate synchronously in the opposite direction. The two layers of flexible material, after being processed by the leveling component, pass between the two rubber extrusion rollers 23 and are subjected to uniform pressure by the counter-rotating rubber extrusion rollers 23, completing the bonding and conveying to the next process. The meshing of two gears 24 ensures that the rotation speed of the two rubber extrusion rollers 23 is completely synchronized, avoiding misalignment or excessive stretching during material bonding and improving bonding consistency; the elastic extrusion of the rubber rollers can expel air bubbles at the bonding interface, improving bonding tightness and meeting the sealing requirements of the packaging industry and the insulation requirements of the electronics industry.

[0022] The workflow of this embodiment is as follows: 1. Place the two layers of flexible material to be bonded at the designated positions of the device. The first layer of flexible material is laid on the top of the first guide plate 11 inside the U-shaped frame 2, and the second layer of flexible material is laid on the bottom of the second guide plate 12. Ensure that the conveying paths of the two layers of material are aligned and that the edges are compatible with the working range of the rubber positive and negative thread rod 21 and the plastic push plate 4.

[0023] 2. Simultaneously start the first motor 10 and the second motor 25. The first motor 10 serves as the power source for the leveling system, driving the first drive rod 8 to rotate via chain transmission. The second motor 25 serves as the power source for the conveying and bonding system, directly driving one of the rubber extrusion rollers 23 on the mounting plate 22 to rotate. At the same time, the eccentric wheels 9 at both ends of the first drive rod 8 and the second drive rod 16 rotate synchronously: the protruding end of the eccentric wheel 9 pushes the first lifting plate 3 to move downward, the first guide rod 6 slides along the top guide hole inside the U-shaped frame 2, the second spring 7 is compressed, and the plastic push plate 4 at the bottom of the first lifting plate 3 contacts the first... The top material of the guide plate 11 opens in a figure-eight shape for one stretching and leveling. Similarly, the protruding end of the eccentric wheel 9 pushes the second lifting plate 13 upward, the second guide rod 14 slides along the bottom guide hole inside the U-shaped frame 2, the reset spring 15 is stretched, and the plastic push plate 4 at the top of the second lifting plate 13 contacts the bottom material of the second guide plate 12 and opens in a figure-eight shape, completing the synchronous leveling of the two layers of material. When the protruding end of the eccentric wheel 9 disengages from the lifting plate, the second spring 7 resets and pulls the first lifting plate 3 upward, and the reset spring 15 contracts and pulls the second lifting plate 13 downward, forming a cyclical leveling action. When the first drive rod 8 rotates, on the one hand, it drives the second drive rod 16 to rotate synchronously and at the same speed through the chain transmission between the first sprocket 17 and the second sprocket 18 at the end; on the other hand, it drives the two rubber positive and negative threaded rods 21 on the outside of the U-shaped frame 2 to rotate through the chain transmission between the third sprocket 19 and the fourth sprocket 20 at the end. The positive and negative threaded sections of the rods apply a continuous outward pulling force in the width direction of the two layers of material to eliminate material wrinkles for the second time.

[0024] 3. After being leveled, the two layers of flexible material enter the area of ​​the rubber extrusion rollers 23 between the mounting plates 22 according to the conveying rhythm. The rubber extrusion rollers 23 driven by the second motor 25 are engaged by the end gear 24, which drives the other rubber extrusion rollers 23 to rotate synchronously in the opposite direction. The two layers of material are subjected to uniform pressure by the two rubber extrusion rollers 23, so that the interface is tightly bonded. At the same time, they are conveyed to the outside of the device by the roller body, completing the single bonding process.
