Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of graphene processing, especially to a graphene film heater with partition heating structure. BACKGROUND

[0002] In today's many fields, such as material preparation, electronic device processing, chemical experiment and daily goods heating, precise and efficient heating demand is growing. Traditional heating device exposes many technical problems when facing these complex and diverse needs, and it is difficult to meet the high standard requirements of modern industrial production and scientific research exploration.

[0003] Traditional heaters mostly adopt single heating mode, that is, the temperature of the whole heating area is uniformly distributed, and it is impossible to differentiate heating for different goods and different parts. In the process of graphene film preparation, from film growth to subsequent modification, annealing and other processes, each stage has completely different requirements for the accuracy, uniformity and distribution mode of temperature. For example, the growth stage may need a specific direction temperature gradient to promote atomic arrangement, while the modification link requires independent temperature regulation of different areas of the film to achieve precise chemical modification. Traditional heaters are difficult to achieve such fine temperature management, which easily leads to uneven quality of graphene films, low yield, and greatly limits the development of graphene industry.

[0004] At the same time, the structural design of traditional heating device lacks flexibility. The platform for placing goods is often fixed, which cannot adapt to the placement needs of goods of different sizes and shapes, not only reduces the heating efficiency, but also may cause safety hazards in the operation process due to improper placement of goods. Moreover, the distance between the heating device and the heated goods is usually not adjustable, and for materials with different heat conduction characteristics, the heating distance cannot be flexibly changed to achieve the best heat transfer effect, resulting in energy waste, prolonged heating time and increased cost.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] In the embodiment, as Figures 1 to 4As shown, a graphene film heater with a partition heating structure includes a frame 1, a placing rack 2 is arranged in the frame 1, a sliding plate 3 is arranged on the placing rack 2, and a placing table 4 is fixed on the sliding plate 3; a partition heating mechanism is further arranged in the frame 1, the partition heating mechanism is located on the upper side of the placing table 4, the partition heating mechanism is adjusted in height by a lifting mechanism, and the output end of the heating mechanism can cover the placing table.

[0022] In this embodiment, the core body is cooperatively constructed by key components such as the frame 1, the placing rack 2, the sliding plate 3, the placing table 4 and the partition heating mechanism. The frame 1 serves as a solid support foundation, providing a stable external framework for the entire device and ensuring the stability of internal components during operation. The placing rack 2 is ingeniously placed inside the frame 1, and it interacts with the frame 1 through a unique connection method, providing support for the installation and movement of subsequent components. The sliding plate 3 is flexibly arranged on the placing rack 2, and the cooperation between the two creates conditions for the flexible adjustment of the placing table 4. The placing table 4 is fixed on the sliding plate 3 and serves as a key platform for carrying heated objects, directly contacting the heated objects. What is particularly prominent is the partition heating mechanism carefully arranged in the frame 1, which is precisely positioned on the upper side of the placing table 4 and can perform partitioned fine heating on the objects on the placing table 4 according to requirements. Moreover, the partition heating mechanism, with the help of the ingeniously designed lifting mechanism, realizes high and free height adjustment, so that its heating output end can perfectly cover the placing table 4 as needed. Precise and uniform heating is crucial in the preparation and processing of graphene films. The frame 1 of the heater with the partition heating structure we use provides a stable foundation support framework for the entire heating system, ensuring that the device as a whole will not shake, displace or be unstable under long-term and high-intensity heating operations, providing a reliable premise for the fine processing of graphene films.

[0023] In one or more embodiments of the present application, two opposite fixed seats 5 are fixed in the frame 1, shaft seats 6 are fixed on the fixed seats 5, first rotating shafts 7 are fixed in the shaft seats 6, mounting seats 8 are fixed on the outer sides of the first rotating shafts, and the placing rack 2 is fixed on the two mounting seats 8; two hinged seats are also fixed in the frame 1, air cylinders 9 are fixed on the hinged seats, the output ends of the air cylinders extend upward and are fixed on the lower side of the placing rack 2, and the placing rack 2 is driven by the air cylinders 9 to adjust the angle.

[0024] In the embodiment, through the cooperation of the fixing seat 5, the shaft seat 6, the first rotating shaft 7 and the mounting seat 8, the placing rack 2 can flexibly change the angle. In the graphene film growth link, different growth stages may require different temperature gradients and heat distribution directions, the placing rack 2 can accurately adjust its own posture according to the process requirements, so that the graphene film substrate carried forms an optimal angle with the heat flow, promotes the uniform growth of graphene and improves the film quality. Meanwhile, the existence of the air cylinder 9 further enhances the accuracy of the adjustment, which can finely adjust the angle of the placing rack 2 at the micro level and meet the stringent setting of the researchers on the graphene film growth conditions.

[0025] In one or more embodiments of the utility model, two rows of limit wheels 10 are fixed on the placing rack 2 and oppositely arranged, the sliding plate 3 is arranged between the two rows of limit wheels 10, the front and rear sides of the sliding plate 3 are fixed through fixed blocks 11 and bolts, and a plurality of handles 12 are further fixed on the upper side of the sliding plate 3.

[0026] In the embodiment, the limit wheel 10 strictly restricts the moving path of the sliding plate 3, ensures that the placing table 4 is stable and smooth when carrying the graphene film sample in and out of the heating area, and will not damage the fragile graphene film due to slight deviation. The fixed block 11 and the bolt firmly fix the sliding plate 3 and provide a solid bearing basis for the placing table 4, which can ensure that the graphene film is in a stable state even if the sample is frequently loaded and unloaded. The setting of the handle 12 further simplifies the operation process, and the operator only needs to apply a little force to conveniently move the placing table 4 on which the graphene film is placed to the ideal heating position, which greatly improves the work efficiency and reduces the errors that may be introduced due to complicated operation.

[0027] In one or more embodiments of the utility model, the lifting mechanism comprises two groups of opposite and vertically arranged sliding rails 13 fixed on the left and right inner sides of the frame 1, the partition heating mechanism is arranged between the two groups of sliding rails 13, a lifting frame 14 is fixed on the upper side of the partition heating mechanism, a driving motor 15 is fixed on the lifting frame 14, a gear box 16 is fixed on the output end of the driving motor 15, two groups of fixed shaft seats 17 are fixed on the two sides of the lifting frame 14, a second rotating shaft 18 is fixed in the fixed shaft seat 17 through a bearing, the two output ends of the gear box 16 are respectively connected with the two sides of the second rotating shaft 18 through rotating arms 19, a gear 20 is fixed on the outer side of the second rotating shaft 18, two opposite toothed racks 21 are fixed on the front side of the frame 1, and the gear 20 is engaged with the toothed racks.

[0028] In this embodiment, the slide rail 13 provides a straight and accurate guide for the lifting of the partition heating mechanism, like laying a special lifting channel for a "temperature control master". After the driving motor 15 is started, the power is orderly distributed to the second rotating shafts 18 on both sides through the gear box 16, and then the gears 20 are stably rolled along the racks 21, so that the partition heating mechanism can accurately adjust the distance from the graphene film according to the thickness, heat conduction characteristics and other factors of the graphene film. When the graphene film is annealed, the appropriate heating distance can not only ensure efficient heat transfer, but also avoid local overheating damage to the film due to too close distance, or insufficient heat due to too far distance affecting the annealing effect. The limiting cylinder 27 and its matched components provide additional safety protection for the partition heating mechanism. When the heating process is over or needs to be paused, the limiting shaft quickly extends to lock the high position of the partition heating mechanism, preventing it from accidentally falling and colliding with the graphene film being processed, and ensuring the safety of precious experimental samples or industrial products.

[0029] In one or more embodiments of the present application, the lifting frame 14 is fixed with two oppositely arranged lifting seats 22, the lifting seat 22 is fixed with a limiting seat 23, the inside upper side of the frame 1 is fixed with two oppositely arranged top plates, the lower side of the top plate is fixed with an inverted seat, the inverted seat is fixed with a limiting cylinder 27, the output end of the limiting cylinder 27 is fixed with a limiting shaft, and when the limiting shaft extends into the through hole on the limiting seat 23, the lifting frame 14 and the partition heating mechanism are limited on the upper side.

[0030] In this embodiment, the lifting frame 14 is fixed with two oppositely arranged lifting seats 22, the lifting seat 22 is fixed with a limiting seat 23, the inside upper side of the frame 1 is fixed with two oppositely arranged top plates, the lower side of the top plate is fixed with an inverted seat, the inverted seat is fixed with a limiting cylinder 27, the output end of the limiting cylinder 27 is fixed with a limiting shaft. When the partition heating mechanism needs to be limited on the upper side, the limiting cylinder 27 is started, the limiting shaft extends into the through hole on the limiting seat 23, and the high position is stable to avoid accidental collision and shaking to cause damage to the components, providing double protection for long-term stable operation of the device.

[0031] In one or more embodiments of the present application, the partition heating mechanism includes a heating box 24 fixed to the lower side of the lifting frame 14, a plurality of heating fans 25 are fixed to the upper side of the heating box 24, a partition frame 26 is fixed in the heating box 24 through bolts, and each region of the partition frame 26 corresponds to each heating fan 25.

[0032] By continuously blowing air by the heating fan 25, heat is evenly blown to the entire heating area. The presence of the partition frame 26 further improves the precision of the heating. When functionalizing a large-area graphene film, different regions may require different temperature stimuli to achieve differentiation. The precisely divided regions of the partition frame 26, in combination with the corresponding heating fan 25, can independently and precisely regulate the temperature of each local part of the graphene film, ensuring that the modification effect of each part can reach the expected value, greatly improving the quality stability and performance consistency of the graphene film product, and laying a solid foundation for the wide application of graphene film in electronic, energy and many other high-end fields.
