Description

Technical Field

[0001] This utility model relates to the field of graphene processing technology, and in particular to a bonding tooling for the production of graphene heaters. Background Technology

[0002] In today's era of rapid technological advancement, graphene heaters are experiencing increasing market demand due to their superior heating performance and broad application prospects. However, the supporting production processes, especially the graphene film lamination process, face numerous technical challenges, severely restricting product quality improvement and large-scale production.

[0003] Traditional bonding methods often lack precise pressure control and angle adjustment mechanisms when bonding graphene films to heater substrates or other components. Due to the ultra-thin and highly flexible physical properties of graphene films, extremely high requirements are placed on the flatness and tightness of the bonding. However, existing simple bonding tools cannot flexibly adjust the rolling pressure and angle according to changes in film thickness and substrate shape, easily leading to uneven film bonding, wrinkles, bubbles, or localized poor bonding. This significantly affects the heating efficiency and stability of the graphene heater, reduces product yield, and increases production costs.

[0004] Meanwhile, traditional lamination processes are not very convenient to operate. On the production line, frequent loading and unloading of graphene films is time-consuming and labor-intensive. Furthermore, due to the lack of effective positioning and limiting methods, the film is prone to displacement during processing. This not only requires repeated calibration by operators but also risks introducing impurities due to operational errors, further affecting lamination quality. In addition, the entire lamination process has a low degree of automation, heavily relying on manual operation, making it difficult to achieve continuous and efficient production, and thus failing to meet the demands of modern large-scale industrial production.

[0005] Furthermore, from a production environment perspective, graphene films have stringent cleanliness requirements. In traditional lamination environments, the lack of effective cleaning aids allows dust, impurities, and other tiny particles in the air to easily adhere to the film surface. During the roll lamination process, these particles become embedded between the film and the substrate, creating defects that severely impair product performance. Moreover, once such problems occur, troubleshooting and repair are extremely difficult, resulting in significant resource waste. Utility Model Content

[0007] The objective of this utility model is achieved through the following technical solution:

The lifting cylinder can precisely adjust the distance between the rolling shaft and the film on the slide plate according to the thickness of the graphene film and the material characteristics of the substrate, thereby ensuring that the rolling pressure is just right and avoiding film bonding defects caused by uneven pressure. At the same time, the cooperation between the adjusting cylinder and the adjusting plate allows the rolling shaft to flexibly adjust the angle according to the irregular changes in the shape of the substrate, ensuring that the graphene film can be tightly and flatly bonded to the complex-shaped parts, significantly improving the uniformity and firmness of the bonding, laying the foundation for the stable and efficient heating performance of the graphene heater, and effectively solving the problem of the difficulty in accurately controlling the pressure and angle in traditional processes. The two rows of limit wheels and limit strips carefully arranged on the base plate provide two-dimensional precise positioning for the slide plate, ensuring that the graphene film placed on it is always in the correct position during the processing without displacement or shaking. On the other hand, the moving frame moves precisely along the slide rail under the drive of the sliding component, allowing the rolling shaft to accurately align with various parts of the film for rolling. This multi-dimensional precise positioning synergy greatly improves the bonding accuracy and reduces the scrap rate. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] In this embodiment, as Figures 1 to 3 As shown, a bonding fixture for the production of graphene heaters includes a base plate 1, a sliding assembly on the base plate 1, a movable frame on the sliding assembly, a bonding rolling assembly on the movable frame, and a sliding plate 2 on the lower side of the bonding rolling assembly for placing graphene films. The bonding rolling assembly includes a lifting cylinder 3 fixed to the movable frame, a lifting plate 4 fixed to the output end of the lifting cylinder 3, and opposing fixing bars 5 fixed to the lower ends of the lifting plate 4. An adjusting plate 6 is rotatably arranged between the two fixing bars 5, and two opposing fixing seats 7 are fixed to the extension end of the adjusting plate 6. A rolling shaft 8 is fixed between the two fixing seats 7 by bearings, and the rolling shaft 8 is located on the upper side of the sliding plate 2.

[0025] In this embodiment, the bonding fixture uses a robust base plate 1 as its basic support platform, supporting all components of the fixture and ensuring stability during high-intensity production operations. A sliding assembly is cleverly designed on the base plate 1, acting like a set of precise "guide rails" to provide a smooth and accurate path for the movement of subsequent components. A movable frame mounted on the sliding assembly serves as a multi-functional support and operating platform, capable of flexible displacement along the sliding assembly to meet processing needs at different locations. The carefully arranged bonding and rolling assembly on the movable frame is the core "processing unit" of the entire fixture, responsible for the crucial bonding and rolling operations on the graphene film, ensuring a tight bond between the film and other components and guaranteeing the heating performance of the heater. Below the bonding and rolling assembly, a dedicated slide plate 2 for placing the graphene film is provided. This not only provides a stable support surface for the film but also, through cooperation with other components, enables convenient operation and precise positioning of the film during processing.

[0026] In one or more embodiments of this utility model, a lower hinge seat 9 is fixed to the upper side of the adjusting plate 6, an upper hinge seat 10 is fixed to the outer side of the lifting plate 4, and an adjusting cylinder 11 is hinged between the upper hinge seat 10 and the lower hinge seat 9.

[0027] In this embodiment, the main structure of the bonding and rolling assembly begins with a lifting cylinder 3 fixed on a moving frame. Like a "strongman," it controls the vertical lifting and lowering of the entire rolling assembly. The output end of the lifting cylinder 3 is stably fixed to the lifting plate 4. When the lifting cylinder 3 receives a command to start, it can precisely push the lifting plate 4 up or down, thereby adjusting the distance between the rolling assembly and the graphene film on the slide plate 2 to adapt to materials of different thicknesses or different processing stages. At the lower ends of the lifting plate 4, two opposing fixing strips 5 are firmly fixed. These two fixing strips 5 provide a stable mounting base for the adjusting plate 6, which is rotatably positioned between them via bearings, giving it flexible rotation capabilities and allowing for fine-tuning of the angle according to the actual processing conditions. The extended end of the adjusting plate 6 is further fixed with two opposing fixing seats 7. The rolling shaft 8 is then stably fixed between these two fixing seats 7 via bearings, ensuring stable rotation during high-speed rolling and accurately bonding the graphene film to the target component, guaranteeing the flatness and tightness of the bonding.

[0028] In one or more embodiments of this utility model, there is a gap between the lower end of the lifting plate 4 and the upper surface of the adjusting plate 6.

[0029] In this embodiment, to achieve more precise angle control, a lower hinge seat 9 is fixed to the upper side of the adjusting plate 6, and an upper hinge seat 10 is fixed to the outer side of the corresponding lifting plate 4. An adjusting cylinder 11 is hinged between the upper hinge seat 10 and the lower hinge seat 9. When the adjusting cylinder 11 extends or retracts, it can precisely apply a rotational torque to the adjusting plate 6, causing it to rotate around the connection point with the fixing strip 5, thereby driving the rolling shaft 8 to adjust the angle. This meets the bonding requirements of graphene films on some special-shaped components or components with high-precision bonding requirements, ensuring that the film can be perfectly bonded in all parts without gaps. At the same time, a gap is intentionally reserved between the lower end of the lifting plate 4 and the upper surface of the adjusting plate 6. This not only provides the necessary space for the rotation of the adjusting plate 6, but also effectively avoids wear or jamming caused by friction between components during movement, ensuring the smooth operation and stability of the entire rolling assembly.

[0030] In one or more embodiments of this utility model, an air blowing plate 12 is fixed to the lower side of the adjusting plate 6. A plurality of air channels are formed inside the air blowing plate 12. A plurality of air inlets are provided on the side of the air blowing plate 12. The air inlets are the inlet ends of the air channels. A plurality of air outlets are also provided on the lower side of the air blowing plate 12. The air outlets communicate with the air channels. The diameter of the air outlets is smaller than the diameter of the air channels. The rolling shaft 8 is located on the front side of the air blowing plate 12.

[0031] In this embodiment, considering the characteristics of the graphene film during the lamination process, an air blowing plate 12 is fixed to the lower side of the adjusting plate 6. The air blowing plate 12 has several carefully constructed air channels, which act as "airflow channels" responsible for delivering a stable airflow. Several air inlets are provided on the side of the air blowing plate 12, serving as the inlets of the air channels. After connecting an external air source, the gas can smoothly enter the air channels. Several air outlets are evenly distributed on the lower side of the air blowing plate 12. The air outlets communicate with the air channels, and the diameter of the air outlets is smaller than the diameter of the air channels. This design allows the incoming gas to form a certain pressure within the air channels before being ejected at high speed from the air outlets. During the rolling operation of the rolling shaft 8, the airflow blown out by the air blowing plate 12 can promptly remove any dust, impurities, or other tiny particles that may be present on the film surface, ensuring the cleanliness of the graphene film. It also helps the film to adhere more smoothly during the rolling process, avoiding lamination defects caused by tiny foreign objects and improving the product yield. Moreover, the rolling shaft 8 is located in front of the air blowing plate 12. This layout allows the air blowing and rolling actions to be carried out in tandem. Air blowing is used for cleaning first, followed by rolling for bonding, which greatly optimizes the process and effect of the bonding process.

[0032] In one or more embodiments of this utility model, the sliding assembly includes two slide rails 13 fixed to the base plate 1 and arranged opposite to each other, a slider 14 is slidably disposed on the slide rails 13, and the moving frame is fixed on the slider; two mounting seats 15 are also fixed on the base plate 1 and arranged opposite to each other, a drive cylinder 16 is fixed on the mounting seat 15, a connecting plate 17 is fixed to one end of the moving frame, and the output end of the drive cylinder 16 is fixed to the side of the connecting plate 17.

[0033] In this embodiment, the sliding assembly mainly consists of two slide rails 13 fixed to the base plate 1 and arranged opposite each other. The slide rails 13 are high-precision linear guides with specially treated surfaces that have an extremely low coefficient of friction, ensuring that the slider 14 can slide quickly and smoothly on them. The slider 14 serves as a connecting component of the moving frame and is tightly fixed to the moving frame, allowing the moving frame to move precisely along the direction of the slide rails 13. To achieve automated driving, two oppositely arranged mounting seats 15 are also fixed on the base plate 1. A drive cylinder 16 is firmly fixed on the mounting seat 15, and the output end of the drive cylinder 16 is connected to one end of the moving frame through a connecting plate 17. When the drive cylinder 16 receives a command from the control system and starts, it can powerfully push the moving frame to reciprocate along the slide rails 13, realizing the rolling and bonding operation of different parts of the graphene film, greatly improving production efficiency and reducing the tediousness and labor intensity of manual operation.

[0034] In one or more embodiments of this utility model, two opposing stops 18 are also fixed on the base plate 1. Each stop 18 is fixed with a stop shaft 19 and a buffer post 20. One end of the stop shaft 19 and the buffer post 20 is in movable contact with both ends of the movable frame.

[0035] In this embodiment, to ensure the safety and stability of the moving frame during high-speed reciprocating motion, two opposing stops 18 are fixed on the base plate 1. Each stop 18 is equipped with a stop shaft 19 and a buffer column 20. The stop shaft 19 serves as a rigid limiting component for the moving frame, precisely preventing it from continuing forward when it reaches its limit position, thus preventing equipment damage due to loss of control. The buffer column 20 acts as a buffer, typically using elastic material or a hydraulic buffer device. When the moving frame approaches its limit position, the buffer column 20 gradually absorbs the kinetic energy of the moving frame, bringing it to a smooth stop. This avoids severe vibrations caused by hard collisions, which could adversely affect the equipment and the graphene film being processed, ensuring the stability and continuity of the production process.

[0036] In one or more embodiments of this utility model, the movable frame includes two sliding plates 21 arranged opposite to each other. The sliding plates 21 are fixed on corresponding sliders 14. A vertical plate 22 is fixed on the sliding plate 14. A horizontal plate 23 is fixed between the upper ends of the two vertical plates 22. The lifting cylinder 3 is fixed to the front side of the horizontal plate 23.

[0037] In this embodiment, as described above, the structure facilitates the installation of other compatible components. For example, during subsequent process upgrades or equipment maintenance, if it is necessary to add new sensors, monitoring equipment, or adjust the parameters of the rolling assembly, the pre-reserved mounting points on components such as the horizontal plate 23 and the vertical plate 22 can be used for easy equipment integration without requiring large-scale modifications to the entire mobile frame structure. This reduces equipment maintenance costs and upgrade difficulty, improves the equipment's scalability and adaptability, and meets the ever-changing process requirements in the production of graphene heaters.

[0038] In one or more embodiments of this utility model, two rows of linearly arrayed limiting wheels 24 are fixed on the base plate 1. The limiting wheels 24 are located inside the two slide rails 13, and the slide plate 2 is slidably disposed between the two rows of limiting wheels. A limiting strip 25 is also fixed on the base plate 1. The limiting strip 25 is used to limit the position of the inner end of the slide plate 2, and the outer end of the slide plate 2 is limited and fixed by a positioning seat 25.

[0039] In one or more embodiments of this utility model, a plurality of handles 26 are fixed on the skateboard 2.

[0040] In this embodiment, two rows of linearly arrayed limiting wheels 24 are fixed on the base plate 1. The limiting wheels 24 are located inside the two slide rails 13, providing a precise sliding track for the slide plate 2. The slide plate 2 is slidably positioned between the two rows of limiting wheels, ensuring that it can only move smoothly along a predetermined direction during operation without deviation or shaking, thus guaranteeing the positional accuracy of the graphene film during processing. Simultaneously, a limiting strip 25 is also fixed on the base plate 1. The limiting strip 25 strictly restricts the position of the inner end of the slide plate 2 from one side, cooperating with the limiting wheels 24 to achieve precise two-dimensional positioning of the slide plate 2. The outer end of the slide plate 2 is fixed by a positioning seat 25. The positioning seat 25 is made of a robust material and can firmly lock one end of the slide plate 2, ensuring that the slide plate 2 will not move due to external force during the rolling and bonding process, providing a solid foundation for the stable processing of the graphene film.

[0041] To further enhance operational convenience, several handles 26 are fixed to the slide plate 2. These handles 26 are distributed in suitable positions on the slide plate 2, allowing operators to easily move the slide plate 2 back and forth by simply gripping the handles 26, enabling rapid loading, unloading, and position adjustment of the graphene film. During production, when it is necessary to replace a new graphene film or inspect the processed film, operators can quickly move the slide plate 2 out of or back to the processing area using the handles 26, greatly shortening operation time, improving production efficiency, and making the entire bonding fixture more user-friendly and efficient.

[0042] After the graphene film is laminated, the slide plate can be pulled out and placed on the heating device to heat the graphene film.

[0043] Working principle of this utility model:

[0044] First, the operator places the graphene film on the slide plate 2, and uses the handle 26 on the slide plate 2 in conjunction with the limiting wheels 24 and limiting strips 25 on the base plate 1 to precisely adjust and fix the position of the slide plate 2. Next, the drive cylinder 16 is activated, which pushes the moving frame to slide along the slide rail 13 via the slider 14, moving the bonding roller assembly to the initial position above the film. During this process, the stop shaft 19 and buffer column 20 on the stop seat 18 ensure the safe operation of the moving frame. Then, the lifting cylinder 3 is activated, driving the lifting plate 4 to rise and fall, adjusting the rolling shaft 8 to the appropriate height. If fine angle adjustment is required, the adjusting cylinder 11 is extended and retracted, causing the adjusting plate 6 to rotate and optimize the posture of the rolling shaft 8. After preparation, the rolling shaft 8 rotates to roll and bond the film. At this time, the air blowing plate 12 works simultaneously, taking in air from the air inlet, blowing air out through the air channel and air outlet to remove impurities from the film and assist in bonding. After the bonding of the current area is completed, the drive cylinder 16 drives the moving frame to move again, repeating the above operation until the entire graphene film is bonded. After lamination, the slide plate is pulled out and placed on the heating device to heat the graphene film.
