Description

[Technical field]

[0001] The present application belongs to the technical field of thin film preparation, and in particular relates to a flattening component for scraping and a thin film preparation device. [Background technology]

[0002] Thin films are two-dimensional materials, usually prepared by solidifying specific materials on the surface of a substrate in various deposition methods. Their components include plastics, adhesives, rubber and other materials. As the thin film industry grows, its product types continue to expand, such as optical films, composite films and superconducting films. These films are widely used in industries such as electronics, machinery and printing. In order to meet the ever-increasing performance requirements of thin films, R&D personnel need to use sample preparation devices to prepare a small amount of thin film samples so that performance tests can be carried out in a timely manner to meet R&D needs.

[0003] During the research and development process, technicians need to perform multiple operations on film samples. Different curing temperatures need to be set and the film thickness needs to be within the preset range in order to accurately test its performance characteristics, such as curing speed and film reaction rate. In addition, the cured film samples need to be completely peeled off for other tests or sample preservation. In the prior art, most film sample preparation devices are not integrated designs and need to be processed in conjunction with other equipment such as ovens and cutting devices. In addition, since most substrate surfaces are not anti-stick treated, the operation is complicated when peeling off film samples, and it is difficult to obtain complete samples. In some cases, technicians even need to use a handheld scraper to gradually peel off from the corners of the sample. When technicians obtain film samples, the operation steps are often cumbersome, and it is difficult to obtain complete film samples.

[0004] Existing thin film sample preparation devices are difficult to flexibly prepare and peel off thin film samples that meet the processing parameters (such as curing temperature and film thickness) of technicians. Therefore, it is necessary to improve the thin film sample preparation equipment to meet the corresponding requirements. [Contents of the utility model]

[Specific implementation method]

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The present application aims to conveniently prepare thin film samples and to precisely control process parameters. In the process of thin film preparation, it is first necessary to ensure that the thin film is flat, and the uniform coating of the liquid material is achieved by combining a flat film-forming surface with a coating component that can perform uniform coating; secondly, after the uniform coating is completed on the flat film-forming surface, it is necessary to precisely control the curing process parameters to prepare the required thin film. From the thin film preparation process, it can be seen that in order to facilitate preparation and easy control of parameters, the main components of the thin film preparation device include a flat component and a film-forming surface. A flat film-forming surface can be easily obtained, so the structure of the flat component is the core of the thin film preparation device, which needs to ensure uniform coating, including adjustable thickness, accurate visualization of thickness, and simple structure.

[0031] This application first optimizes the design of the flattening components in the thin film preparation device, see Figure 1-Figure 3 , Figure 1 It is a schematic diagram of the overall structure of the leveling component of this application. Figure 2 is a schematic structural diagram of a thin film preparation device including a flattening component, Figure 3 yes Figure 2 In the partial enlarged view of the dotted frame part, the flattening component will cooperate with the film-forming base component 310, the base 330 and other components to form a complete thin film preparation device. The flattening component in a preferred embodiment of the present application adjusts the displacement of the scraping component 110 and the distance measuring component 130 through the position adjustment component 120 to achieve precise position adjustment, which is suitable for accurate control of the process parameters of thin film sample preparation.

[0032] The leveling assembly for scraping includes a scraping component 110, a position adjustment component 120, a distance measuring component 130, a mounting beam 140 and a carrier 150. The scraping component 110 and the distance measuring component 130 are arranged on the mounting beam 140; wherein, the scraping component 110 includes a scraping end and a fixed end, the scraping end is used for scraping liquid substances, and the scraping end can be selected as a scraper, a roller, etc., and the specific structure is not limited. In this embodiment, a scraper is selected; the scraping component 110 is detachably connected to the mounting beam 140 through the fixed end, and the specific method includes connecting to the mounting beam 140 through bolts, which is convenient for replacing the scraping component 110; the distance measuring component 130 is fixedly connected to the mounting beam 140, and the position of the distance measuring component 130 is fixed, which is used to accurately measure the position of the scraping component 110.

[0033] The position adjustment component 120 is disposed between the mounting beam 140 and the supporting frame 150 , and is used to adjust the position movement of the mounting beam 140 relative to the supporting frame 150 . The leveling component integrates the scraping component 110 and the distance measuring component 130 into the mounting beam 140, and ensures that the relative position between the mounting beam 140 and the supporting frame 150 is adjustable through the position adjustment component 120. When the supporting frame 150 is fixedly installed, the distance between the scraping component 110 and the target position can be accurately controlled. The scraping component 110 and the distance measuring component 130 are connected to the mounting beam 140. When used, adjusting the position of the mounting beam 140 can simultaneously adjust the distance between the scraping component 110 and the distance measuring component 130 relative to the target position, and accurate calculations are performed through the sizes of related components and specific settings. For example, the distance measuring component 130 selects a dial indicator, and sets a corresponding reference table 360. By measuring the data of the dial indicator and based on the size parameters of the scraping component 110, the gap size between the scraping end of the scraping component 110 and the film forming surface 320 is accurately calculated.

[0034] Specifically, the position adjustment component 120 includes a first mounting end 210, a second mounting end 260 and a distance adjustment component 270. The first mounting end 210 is fixedly connected to the mounting beam 140, the second mounting end 260 is fixedly connected to the supporting frame 150, and the distance adjustment component 270 adjusts the distance between the first mounting end 210 and the second mounting end 260.

[0035] The specific form of the support frame 150 can be a door-shaped frame composed of a crossbeam and two columns, the lower end of the column can be mounted on the mounting end of the translation module (340) in the film preparation device, the second mounting end 260 in the position adjustment component 120 is fixedly connected to the column, and the specific form of the mounting end is not limited. A guide rail can also be included between the first mounting end 210 and the second mounting end 260, and the adjustment direction of the position adjustment component 120 is set along the height direction of the column through the guide rail.

[0036] See also Figure 4 , Figure 41 is a schematic diagram of the internal structure of the position adjustment component 120 in an embodiment of the present application. Specifically, the distance adjustment member 270 includes a support block 220, a matching slider 230 and a bolt adjuster 240. The ends of the support block 220 and the matching slider 230 that are close to each other are provided with inclined surfaces, and the support block 220 and the matching slider 230 abut against each other through the inclined surfaces; the support block 220 is slidably connected to the second mounting end 260, and the matching slider 230 is fixedly clamped to the first mounting end 210; the bolts in the bolt adjuster 240 are sequentially penetrated and spirally connected to the second mounting end 260. The second mounting end portion 260 and the support block 220 are connected by rotating the bolt to realize the movement of the support block 220 along the rotation axis direction of the bolt, and the support block 220 itself does not rotate, so that the inclined surface on the support block 220 produces a resistance effect on the inclined surface on the matching slider 230, further driving the position of the matching slider 230 to move, thereby indirectly realizing the relative displacement in the vertical direction between the first mounting end portion 210 and the second mounting end portion 260, so that the mounting beam 140 also moves in the vertical direction relative to the position of the support frame 150.

[0037] The distance measuring component 130 is a dial indicator. The dial indicator uses a rack gear or a lever gear transmission to convert the linear displacement of the measuring rod into the angular displacement of the pointer. The structure is relatively simple, and the transmission mechanism is a gear system, the transmission mechanism has low inertia, and has a large measurement range. When using the dial indicator, it is fixed on the mounting crossbeam 140, so that the measuring head at one end of the measuring rod is against the reference table 360. When adjusting the mounting crossbeam 140, the measuring head can be displaced to obtain the deflection of the pointer on the dial of the dial indicator. By obtaining relevant values, the distance of the scraping component 110 relative to the target position is accurately calculated. When setting, the axis of the measuring rod is perpendicular to the surface of the reference table 360 ​​to ensure measurement accuracy.

[0038] Specifically, the position adjustment components 120 include two, which are respectively arranged at the two ends of the length direction of the installation beam 140, and a linkage component 160 is included between the two position adjustment components 120, and synchronous adjustment is achieved through the linkage component 160. The scraping component 110 is used to spread the liquid material evenly on a plane. The uniform size helps to maintain a uniform spreading thickness. The scraping component 110 will move in a direction parallel to the scraping target plane, and the scraping end is usually set to be in a straight line shape and needs to be parallel to the surface to be scraped. Therefore, in a further solution, at both ends of the installation beam 140, the distances at both ends are accurately measured and confirmed to ensure that the thickness of the scraped film is the same. On this basis, the linkage component 160 can be further used to adjust the two position adjustment components 120 at the same time and in the same amount. For example, a common transmission shaft is used with the same transmission matching components. The movement of the transmission shaft can simultaneously make the same adjustment to the two position adjustment components 120, so that the two position adjustment components 120 produce the same movement. Specifically, the two ends can produce the same displacement in the vertical direction, so that the scraping component 110 always remains horizontal. In this way, it is easy to adjust the moving distance of the installation beam 140, simplify the operation process, and avoid errors such as human misjudgment.

[0039] On the basis of accurately controlling the thickness of the film, in order to accurately control the curing temperature and realize accurate control of the parameters of the film preparation process, the present application further provides a film preparation device using the above-mentioned flattening component, please refer to Figure 2 , Figure 2 It is a structural schematic diagram of the thin film preparation device of the present application. The thin film preparation device specifically includes the aforementioned leveling component, the film forming base component 310 and the base 330. The film forming base component 310 includes a flat film forming surface 320, and the length direction and width direction of the film forming surface 320 are both arranged along the horizontal direction. A translation module 340 is installed on the base 330, and the carrier frame 150 in the leveling component is installed on the mounting end of the translation module 340. The translation module 340 may include structures such as guide rails and mounting seats that cooperate with the guide rails. In addition, a translation module 340 with a drive motor may be used to realize automatic control of the translation process. In this embodiment, the specific method of the translation module 340 may include two sets of guide rails, which are respectively installed on the base 330 and are parallel to both sides of the length direction of the film forming surface 320, and the length direction of the guide rails is perpendicular to the length direction of the mounting beam 140. The guide rail includes a mounting seat, which can translate on the guide rail. The mounting seat serves as the mounting end of the carrier frame 150. The bottom ends of the two columns of the carrier frame 150 are respectively connected to the mounting seat. The controllable translation of the carrier frame 150 is achieved through the above structure, ultimately ensuring the controllable translation of the leveling component.

[0040] Specifically, a temperature control component is also installed in the film-forming base assembly 310, and the temperature control component includes a heating unit, a cooling unit and a controller, wherein the controller is electrically connected to the heating unit and the cooling unit. In order to obtain high-quality thin film products, the temperature during the film curing process must be strictly controlled. The existing film preparation will use additional other equipment for processing, such as controlling the curing temperature through an external oven. The film preparation device of the present application integrates the temperature control component into the film-forming base assembly 310. Since the film is formed on the film-forming surface 320 of the film-forming base assembly 310, by combining a controller including a temperature measuring component, the curing temperature of the film on the film-forming surface 320 can be more accurately controlled. In the specific use process, since it includes a heating unit and a cooling unit, different temperature demand scenarios can be realized, such as maintaining a fixed temperature, continuously heating up, continuously cooling down, heating up first and then cooling down, etc. Different temperature curves can be realized, so as to meet the temperature requirements in the preparation process of different materials.

[0041] The film-forming surface 320 is coated with an anti-sticking layer or installed with an anti-sticking plate. For the film that has been cured, it is necessary to be able to efficiently and completely remove the film from the film-forming surface 320. Coating an anti-sticking layer or installing an anti-sticking plate on the film-forming surface 320 can facilitate the peeling of the film material, and can avoid the film being difficult to remove due to sticking, or the film being damaged due to sticking. The anti-sticking layer or anti-sticking plate on the film-forming surface 320 can avoid problems related to sticking. In addition, the film-forming surface 320 can also be made directly of an anti-sticking material.

[0042] Specifically, the base 330 also includes a reference table 360, and the distance measuring component 130 in the leveling assembly uses the reference table 360 ​​as a reference for distance measurement. This application uses a dial indicator for measurement. Due to the characteristics of the dial indicator, a standard position needs to be set. By setting a reference table 360 ​​on the base 330, calibration and accurate measurement of position parameters can be achieved.

[0043] Specifically, the base 330 also includes a rotating device, which adjusts the horizontal tilt angle of the base 330. The base 330 can be connected to a main support column through a joint bearing at the geometric center of the base 330, and support components can be arranged around it. By moving the support components up and down, the base 330 can be at a certain angle with the horizontal plane in conjunction with the joint bearing. The specific scenarios of film formation are diverse, and it is impossible to ensure that the film is completely scraped and formed on the horizontal plane. There may be scenarios where the film is formed on the inclined surface. In order to study the properties of the film after solidification on the inclined surface, the inclined surface is simulated during the sample preparation process, and the horizontal tilt angle of the base 330 is adjusted by the rotating device. Since the film-forming base assembly 310 and the flattening assembly are arranged on the base 330, the film-forming surface 320 has the same horizontal tilt angle, and the scraping surface of the flattening assembly also has a horizontal tilt angle. In this state, scraping and curing are performed, and the properties of the film scraped and cured at different tilt angles can be studied, which expands the application scenarios of the film preparation device.

[0044] Specifically, the film-forming base assembly 310 also includes an overflow trough 350, which can be detachably installed in the film-forming base assembly 310. When the film is formed by scraping through the flattening assembly, the initial amount of glue is usually more than the required amount of glue in order to ensure the integrity of the film on the film-forming surface 320 and the convenience of production. In order to better collect the excess glue, the overflow trough 350 is arranged around the film-forming surface 320. The specific arrangement around the overflow trough 350 can be an integral structure, or a strip groove can be independently arranged at the corresponding position of each edge of the film-forming surface 320 to collect the excess glue at each edge. The excess glue from scraping is collected through the overflow trough 350. The overflow trough 350 can be manufactured in the form of an independent component, and a corresponding placement position is formed on the film-forming base assembly, such as opening a placement groove that matches the overflow trough 350, and the overflow trough 350 is inserted into a specific placement position, so that the overflow trough 350 can be replaced regularly and the excess glue can be further recycled. In addition, the inside of the overflow groove 350 is also treated with anti-sticking. Usually, after the scraping is completed, it will be heated and cured. During the heating and curing, the glue in the overflow groove 350 will also be cured. The anti-sticking treatment is helpful for cleaning.

[0045] Specifically, the base 330 also includes a film-lifting component, which is an air knife or a scraper component. The film-lifting component is used to assist in separating the film from the film-forming surface 320, thereby reducing the instability of manual operation and improving the film-making efficiency. In this embodiment, the film-lifting component is specifically selected as an air knife with two air outlets, one air knife is aligned with the gap between the film and the film-forming surface 320, and is kept parallel to the film-forming surface 320, and the other air knife is set at an angle to the film-forming surface 320. The air knife can help the film to roll up after peeling, so as to facilitate further and better separation of the film.

[0046] Specifically, it includes at least two film-forming surfaces 320, and the corresponding scraping components 110 are arranged on the flattening component, and each film-forming surface 320 is respectively configured with an independent temperature control component. The thin film preparation device of the present application can be used to prepare a small amount of thin film samples, so as to carry out relevant performance tests in a timely manner. In the research and development process, the preparation parameters, such as thickness, curing temperature, etc., are usually adjusted. By setting multiple film-forming surfaces 320, and correspondingly setting the scraping components 110 and the temperature control components, it is possible to obtain films prepared under multiple parameters in a single sample preparation process. For example, by adjusting the size of the corresponding scraping component 110, adjusting the installation position on the mounting beam 140, or adjusting the height of each film-forming surface 320, the distance between the scraping end and the film-forming surface 320 is different, so as to study the properties of films of different thicknesses, and by adjusting the temperature of each area, the properties of the film at different curing temperatures can be studied, so as to obtain films of multiple different parameters in a single preparation process.

[0047] Specifically, it also includes a cutting component, which cuts the film on the film-forming surface 320. In the above content, an excess amount of glue can be used to prepare a complete film on the film-forming surface 320, and the excess glue can be collected through the overflow trough 350. In this process, there is a possibility that the colloid on the film-forming surface 320 and the colloid in the overflow trough 350 are connected together. After drying, the film on the film-forming surface 320 may also be connected to the solidified material in the overflow trough 350, which may cause the film to be damaged or difficult to peel off when separating the film. The cutting component is used to cut the film on the film-forming surface 320 independently, thereby avoiding the above problems. A specific implementation method is laser cutting, which cuts the film on the film-forming surface 320 by laser, and controls the energy and position of the laser to accurately control the cutting process. In addition, according to the test needs, the film of the required shape or size can be directly cut out, and the cutting position can also be used as the starting position of the film assembly. For example, the air knife blows air to the cutting position to separate from the cutting position.

[0048] The specific method of using the film preparation device of the present application is introduced below. First, adjust the flattening component to the starting position, take 5-15mL of the prepared glue solution (confirm that the viscosity of the ingredients is 15-30″) and pour it to one side of the scraper. Adjust the bolt adjuster to move the mounting crossbeam to adjust the distance between the scraping component and the film-forming surface. Confirm that the film thickness is 10μm according to the dial indicator, and start automatic scraping. After the scraping is completed, adjust the temperature of the film-forming surface to 100℃ through the temperature control component, bake for 5 minutes to volatilize the solvent, and reduce the plate surface temperature to 50-60℃ after the solvent is completely evaporated, giving the glue layer aging time. After the glue layer reacts completely, complete the film sampling through the film-forming component to examine the flatness and strength of the film surface, or measure the reaction rate, etc. In addition, the aforementioned components and action modes can be extended and selected on the basis of the above methods.

[0049] As can be seen from the above, the present application sets the scraping component and the distance measuring component on the mounting beam, and realizes the relative position adjustment of the mounting beam and the carrier through the position adjustment component. After the carrier is fixed, the distance adjustment between the scraping component and the target position is realized. The distance measuring component can accurately measure the distance and accurately control the processing parameters in the film preparation process. The film preparation device including the flattening component has a flat film-forming surface, and the mobile stability of the flattening component is realized by the translation module; the temperature control component is set in the film-forming base assembly, which can accurately control the film curing temperature without the transfer of any components or devices, and the film preparation is completed in one device. By integrating multiple functions in related components and devices, the film preparation process is simple to operate and highly practical, and the preparation process parameters are accurately controllable through structural coordination.

[0050] The above is only a specific implementation of the present application, and any other improvements made based on the concept of the present application are deemed to be within the protection scope of the present application.
