Description

Technical Field

[0001] This utility model relates to the field of copper foil adhesive application technology, specifically, to a high-precision copper foil adhesive application device. Background Technology

[0002] Copper foil, as an important metallic material, has been widely used in many fields such as electronics, electrical engineering, new energy, and aerospace due to its excellent electrical conductivity, thermal conductivity, corrosion resistance, and good machinability. In the electronics field, copper foil is a key basic material for manufacturing printed circuit boards (PCBs), providing a stable conductive path for electrical connections between electronic components. In the new energy field, copper foil in lithium-ion batteries serves as the negative electrode current collector, playing a crucial role in collecting and conducting current. Its performance directly affects key indicators such as battery energy density, charge and discharge efficiency, and lifespan.

[0003] In the production process of applying adhesive to copper foil, the winding roller collects the coated copper foil. Its installation and post-collection processing are crucial. However, existing technologies have many shortcomings. During installation, the lack of effective limiting mechanisms makes it difficult to ensure the stability of the winding roller during operation, leading to positional deviations and uneven copper foil winding, affecting subsequent processing and use. Furthermore, the transfer and replacement of the copper foil after collection is cumbersome. Existing support and movement methods are inefficient, requiring multiple people and consuming significant manpower and time. During transfer, the lack of suitable support and guiding structures makes the winding roller susceptible to collisions and vibrations, damaging the wound copper foil and reducing product quality. Therefore, those skilled in the art provide a high-precision copper foil adhesive application device to solve the problems mentioned in the background. Utility Model Content

[0013] This invention, by incorporating a limiting component and a support component, allows the internal support of the winding roller during installation, thus securing it. The user can install a rod on the outer wall of the extrusion plate and a hole inside the winding roller, effectively limiting its position. After the winding roller finishes collecting the copper foil, the support component is moved below it. A hydraulic push rod and a lifting frame then support the collected winding roller. A rotating unit drives the second support platform to rotate. Since the omnidirectional trolley is located below the winding roller, its wheels rotate with it, and the second support platform rotates 90 degrees. At this point, the user retracts the limiting component, freeing it from limiting the winding roller. The support component can then be pushed to move the winding roller away, completing the collection process. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a high-precision copper foil adhesive applicator, including a support plate 1, a take-up roller 4, and a copper foil roller 5. The upper top of the support plate 1 is provided with a processing mechanism 2 for processing copper foil. The upper top of the support plate 1 is located on one side of the processing mechanism 2 and is provided with a drying box 3 for heating the copper foil after adhesive application. The upper top of the support plate 1 is located on the side of the drying box 3 away from the processing mechanism 2 and is provided with a limiting component 6 for internal support of the take-up roller 4. The upper top of the support plate 1 is provided with a rotating unit 8 for driving the limiting component 6 to rotate. The upper top of the support plate 1 is located below the take-up roller 4 and is provided with a support component 7 for supporting the take-up roller 4.

[0023] It should be noted that the processing mechanism 2 is located at the top of the support plate 1, which can precisely process the copper foil, ensure the quality of the adhesive bonding, and improve product precision. The drying box 3 is located on one side of the processing mechanism 2, which can quickly heat and dry the copper foil after the adhesive has been applied, so that the adhesive is firmly attached to the copper foil, avoiding the problem of falling off during subsequent use and improving product stability. The limiting component 6 is located at the top of the support plate 1 and on the side of the drying box 3 away from the processing mechanism 2, which can reliably support the winding roller 4, ensuring the stability of the winding roller 4 during the winding process and preventing the copper foil from shifting or wrinkling during winding. The rotating unit 8 is located at the top of the support plate 1, which can drive the limiting component 6 to rotate, thereby realizing the rotation of the winding roller 4, which facilitates separation from the limiting component 6 and removes the winding roller 4 from the limiting component 6. The support component 7 is located below the winding roller 4, providing stable support for the winding roller 4 and enhancing the stability of the winding process.

[0024] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the processing mechanism 2 includes a placement platform 22 fixedly connected to the top of the support plate 1. Two first support frames 21 are symmetrically fixedly connected to the top of the support plate 1 below the placement platform 22. A copper foil roller 5 is rotatably sleeved on one side of the two first support frames 21. Two second support frames 221 are symmetrically fixedly connected to the top of the placement platform 22. A copper foil adhesive roller 222 for applying adhesive to the copper foil is rotatably sleeved on one side of the two second support frames 221. Two connecting frames 223 are symmetrically fixedly connected to the outer wall of the placement platform 22. A first extrusion roller 22 that abuts against the copper foil adhesive is rotatably sleeved on one side of the two connecting frames 223. 4. The top of the support plate 1 is symmetrically fixedly connected to two sets of third support frames 23 on one side of the first support frame 21. Each set of third support frames 23 has a second extrusion roller 24 rotatably sleeved inside. The two sets of third support frames 23 have different heights. The shorter third support frame 23 is closer to the first support frame 21. The top of the support plate 1 is symmetrically fixedly connected to two fourth support frames 25 on the side of the higher third support frame 23 away from the first support frame 21. The two fourth support frames 25 are symmetrically rotatably sleeved on the side of the two fourth support frames 25 that are close to each other. A gap is reserved between the two third extrusion rollers 26 for copper foil to pass through for adhesive to be applied to copper foil.

[0025] It should be noted that the placement platform 22 fixed to the top of the support plate 1 provides stable support for each component. Two first support frames 21 are symmetrically fixed below the placement platform 22, allowing the copper foil roller 5 to rotate and engage, ensuring the smoothness of copper foil conveying. The two second support frames 221 at the top of the placement platform 22 allow the copper foil adhesive roller 222 to rotate and engage, accurately adhering the adhesive to the copper foil. The first extrusion rollers 224 on the two connecting frames 223 can abut against the copper foil adhesive, further compacting the bonding effect and preventing air bubbles or gaps between the adhesive and the copper foil. The two sets of third support frames 23 at the top of the support plate 1 with different heights are as follows: the shorter one is closer to the first support frame 21, and its internal second extrusion roller 24 can perform preliminary extrusion and shaping of the copper foil; the taller third support frame 23 is further away from the first support frame 21, and together with the two fourth support frames 25 and the two third extrusion rollers 26, the gap between the two third extrusion rollers 26 allows the copper foil to pass smoothly with the copper foil adhesive, and the second extrusion ensures a tight bond.

[0026] As one implementation method in this embodiment, please refer to Figure 1 - Figure 6 As shown, the limiting assembly 6 includes a sliding frame 61 fixedly connected to the support plate 1 with its top end located on one side of the drying chamber 3. A first support platform 62 is slidably sleeved inside the sliding frame 61. A right-angle frame 64 is fixedly connected to the outer wall of the drying chamber 3. A first electric push rod 65 is fixedly connected to the side of the right-angle frame 64 near the first support platform 62. The telescopic end of the first electric push rod 65 is fixedly connected to the outer wall of the first support platform 62. A second support platform 63 is provided at the top of the support plate 1 on the side of the first support platform 62 away from the first electric push rod 65. A second electric push rod 66 is fixedly connected to the side of the second support platform 63 away from the first support platform 62. A camshaft 672 is rotatably sleeved on the side of the first support platform 62 near the second support platform 63 via a bearing. The bearing inside the second support platform 63 is inserted into the camshaft 672. The side of the camshaft 672 near the second electric push rod 66 is fixed. A second guide plate 671 is connected to a second support platform 63, which is rotatably sleeved on the side of the second support platform 62. A push rod 661 is slidably connected between the second guide plate 671 and the first guide plate 67. The telescopic end of the second electric push rod 66 passes through the second support platform 63, the first guide plate 67 and the push rod 661 and is rotatably sleeved. Several first protrusions 662 are fixedly connected to the outer wall of the push rod 661 in a ring array. Three extrusion plates 663 are slidably sleeved in a ring array on the side of the second guide plate 671 and the first guide plate 67 that are close to each other. Three second protrusions 664 are fixedly connected to the side of the three extrusion plates 663 that are close to the push rod 661. Each second protrusion 664 is slidably sleeved on the outer wall of each first protrusion 662. The first protrusions 662 and the second protrusions 664 are abutted together. The take-up roller 4 is sleeved on the outer wall of the three extrusion plates 663.

[0027] It should be noted that the sliding frame 61 is fixed to one side of the drying chamber 3 at the top of the support plate 1. The first support platform 62 can slide inside it. In conjunction with the first electric push rod 65, the position of the first support platform 62 can be flexibly adjusted to adapt to different specifications of winding requirements. The right-angle frame 64 provides stable support for the first electric push rod 65 to ensure accurate extension and retraction. The second support platform 63 works in conjunction with the first support platform 62. The second electric push rod 66 is fixed to one side of the second support platform 63. Through the linkage of the push rod 661, the first guide plate 67 and the second guide plate 671, power transmission is realized. When the second electric push rod 66 is driven, it can drive the three extrusion plates 663 to expand outward or contract inward simultaneously, accurately supporting or relaxing the outer winding roller 4, so that the winding roller 4 maintains high stability during the rotation and winding process, avoiding uneven winding of copper foil due to shaking or deviation. This effectively improves the quality and efficiency of copper foil winding. Since the second guide plate 671 and the first guide plate 67 are rotatably sleeved with the first support platform 62 and the second support platform 63 respectively, gears can be installed on the outer wall of the second guide plate 671 or the first guide plate 67, and motors and gears can be installed on the outer wall of the first support platform 62 or the second support platform 63. Thus, the meshing motion of the two gears drives the first guide plate 67 and the second guide plate 671 to rotate. The three extrusion plates 663 are slidably sleeved with the first guide plate 67 and the second guide plate 671, so the extrusion plates 663 can also rotate. Since the extrusion plates 663 are located inside the winding roller 4 and limit their movement, they can drive the winding roller 4 to rotate. The copper foil that has been glued is located on the outer wall of the winding roller 4. In this way, the winding purpose can be achieved.

[0028] As one implementation method in this embodiment, please refer to Figure 5 As shown, the support assembly 7 includes a universal movable trolley 71 that is slidably connected to the support plate 1 and located below the take-up roller 4. Auxiliary telescopic frames 72 are fixedly connected to the four corners of the top of the universal movable trolley 71. A hydraulic push rod 73 is fixedly connected between every two auxiliary telescopic frames 72 at the top of the universal movable trolley 71. The telescopic ends of the four auxiliary telescopic frames 72 and the telescopic ends of the two hydraulic push rods 73 are fixedly connected to a lifting frame 74 that abuts against the take-up roller 4.

[0029] It should be noted that the omnidirectional movable trolley 71 is slidably connected to the top of the take-up roller 4 on the support plate 1, and can move freely to facilitate quick adjustment of the support points according to the actual production situation, thus enhancing the flexibility of the equipment layout. The auxiliary telescopic frames 72 fixed at the four corners of its top end work in conjunction with the hydraulic push rods 73 located between every two auxiliary telescopic frames 72. The telescopic ends of the four auxiliary telescopic frames 72 and the two hydraulic push rods 73 work together to lift the frame 74, which can precisely control the height of the lift frame 74. When the take-up roller 4 needs to be installed or removed, the height of the lift frame 74 can be lowered for easy operation. During the winding process, the height of the lift frame 74 can be adjusted in real time according to the thickness and weight of the copper foil being wound, so that the take-up roller 4 is always in a suitable working position, ensuring the stability and neatness of the winding. Moreover, the combined design of the auxiliary telescopic frames 72 and the hydraulic push rods 73 provides strong support force, which can effectively bear the weight of the take-up roller 4 and the copper foil, avoiding the take-up roller 4 from falling or shaking due to insufficient support, thereby improving the quality and production efficiency of copper foil winding.

[0030] As one implementation method in this embodiment, please refer to Figure 1 - Figure 3 As shown, the rotating unit 8 includes an inner groove 81 formed at the top of the support plate 1. The bottom of the inner groove 81 is rotatably connected to a first gear 84 and a second gear 85, which mesh and drive each other. A protective cover 82 is sleeved above the first gear 84 and the second gear 85, and the bottom of the protective cover 82 is fixedly connected to the bottom of the inner groove 81. A cover plate 83 is bolted to the end of the inner groove 81, and the top of the support plate 1 is flush with the top of the cover plate 83. A drive motor 86 is fixedly connected to the top of the cover plate 83. The output end of the drive motor 86 passes through the cover plate 83 and the protective cover 82 and is fixedly connected to the center of the second gear 85. The top of the first gear 84 passes through the protective cover 82 and the cover plate 83 and is fixedly connected to the center of the bottom of the second support platform 63.

[0031] It should be noted that the inner groove 81 is located at the top of the support plate 1, providing a concealed and safe installation space for the internal transmission components. This effectively avoids interference and damage to the transmission components from external factors, extending the service life of the equipment. The first gear 84 and the second gear 85 mesh at the bottom of the inner groove 81. This gear transmission method features accurate transmission ratio, smooth transmission, and high efficiency, ensuring the precision and stability of power transmission. The protective cover 82 is fitted over the first gear 84 and the second gear 85, and its lower end is fixedly connected to the bottom of the inner groove 81, preventing dust from entering. Dust and debris enter the gear transmission area, further protecting the gears and reducing wear. The cover plate 83 is bolted to the end of the inner groove 81, and the top of the support plate 1 is flush with the top of the cover plate 83. This ensures that the support plate is flat, facilitating the movement of personnel and equipment, and also makes it easy to inspect and maintain the internal gears. The drive motor 86 is fixed to the top of the cover plate 83, and its output end passes through the cover plate 83, the protective cover 82, and is fixedly connected to the center of the second gear 85, providing strong power for the gear transmission. The first gear 84 drives the second support platform 63 to rotate, thereby enabling the easy disassembly of the winding roller 4.

[0032] Working principle: When installing the take-up roller 4, the limiting component 6 plays a role. The first electric push rod 65 extends and retracts to push the first support platform 62 to slide in the sliding frame 61 to a suitable position. The second electric push rod 66 drives the push rod 661. The first protrusion 662 on the push rod 661 abuts and slides against the second protrusion 664 on the extrusion plate 663, so that the three extrusion plates 663 expand outward to internally support and restrain the inside of the take-up roller 4. The user can install the insertion rod on the outer wall of the extrusion plate 663 and set the insertion hole inside the take-up roller 4 to effectively limit the position of the take-up roller 4.

[0033] In the processing mechanism 2, the copper foil on the copper foil roller 5 is glued by the copper foil adhesive roller 222 on the placement table 22, and then squeezed multiple times by the first extrusion roller 224, the second extrusion roller 24 and the third extrusion roller 26 to ensure that the copper foil and the copper foil adhesive can be stable during the bonding process and to ensure the quality of the adhesive. After the bonding is completed, the copper foil enters the drying oven 3 to dry, so that the connection is tighter.

[0034] After the take-up roller 4 finishes collecting the copper foil, the omnidirectional movable trolley 71 of the support assembly 7 slides below the take-up roller 4. The hydraulic push rod 73 and the auxiliary telescopic frame 72 drive the lifting frame 74 to rise and support the take-up roller 4. The drive motor 86 of the rotating unit 8 drives the second gear 85, and the first gear 84 meshing with the second gear 85 rotates, thereby driving the second support platform 63 to rotate 90 degrees. Since the omnidirectional movable trolley 71 is located below the take-up roller 4, its bottom omnidirectional wheel rotates with the take-up roller 4. Finally, the limiting assembly 6 retracts, releasing the limitation on the take-up roller 4. Then, the first electric push rod 65 drives the first support platform 62 to move linearly. At this time, the bearing inside the first support platform 62 separates from the camshaft 672 and the second guide plate 671. Since the support assembly 7 supports the take-up roller 4, the take-up roller 4 can be taken away by pushing the support assembly 7 to complete the collection. The components work together in the whole process to achieve efficient and accurate copper foil backing and winding.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
