Description

Technical Field

[0001] This utility model relates to the field of coating tooling technology, and in particular to a brush coating clamping mechanism. Background Technology

[0002] In the heat dissipation system of power electronic equipment such as inverters, ceramic insulating sheets are usually used as the heat conduction medium between the Insulated-Gate Bipolar Transistor (IGBT) module and the heat sink. By uniformly coating thermal grease on both sides of the ceramic sheet to fill the contact gap, efficient heat conduction is ensured.

[0003] Existing coating fixtures generally consist of a fixing component, a grease reservoir, and a scraping component. This fixture holds a ceramic sheet in the fixing component, exposing the area to be coated to the scraping area. During operation, the fixing component holding the ceramic sheet is immersed in the open container containing thermal grease, and then vertically lifted, allowing the ceramic sheet to pass through the limiting slit of the scraper at the top of the reservoir. Excess grease is scraped off using the edge of the scraper to form a uniform coating. However, this clamping mechanism has poor holding effect on the ceramic sheet, making it prone to displacement or detachment during coating; secondly, it can only process one ceramic sheet at a time, resulting in low processing efficiency. Utility Model Content

[0004] This utility model provides a brush coating clamping mechanism to solve the defects of easy displacement or detachment during the coating process in the prior art. Through the mechanical limiting of the limiting through groove and the synergistic effect of the clamping of the first hollow part and the second hollow part, the technical defect of easy displacement and detachment of ceramic pieces is solved. The limiting through groove adopts a multi-groove parallel layout, which can simultaneously clamp multiple ceramic pieces for batch coating, effectively improving the processing efficiency per unit time.

[0005] The brush-coating clamping mechanism provided by this utility model includes:

[0006] The first clamping component includes a first hollow portion, wherein the first hollow portion is provided with a plurality of through holes spaced apart;

[0007] A second clamping assembly, one end of which is rotatably connected to one end of the first clamping assembly, the second clamping assembly comprising:

[0008] The second hollow section has a position and shape that correspond to the position and shape of the first hollow section, and the second hollow section is provided with multiple through holes at intervals.

[0009] Multiple limiting slots are spaced apart on the clamping side of the second hollow part, and the limiting slots are used to limit the position of the part to be clamped.

[0010] According to the brushing clamping mechanism provided by this utility model, the hollow area of ​​the first hollow part is smaller than the hollow area of ​​the second hollow part.

[0011] According to the brushing clamping mechanism provided by this utility model, the first hollow part includes a plurality of first mesh units, the number, position and shape of the first mesh units are all corresponding to the number, position and shape of the limiting through grooves, and each first mesh unit includes a plurality of through holes arranged at intervals;

[0012] And / or, the second hollow portion includes a plurality of second mesh units, the number, position and shape of the second mesh units corresponding to the number, position and shape of the limiting through slots, and each second mesh unit includes a plurality of through holes spaced apart.

[0013] According to the brushing clamping mechanism provided by this utility model, the second clamping component further includes:

[0014] A second clamping plate, one end of which is rotatably connected to one end of the first clamping assembly, and the second hollow portion is provided on the second clamping plate;

[0015] A limiting plate is detachably disposed on the clamping side of the second clamping plate, and a plurality of the limiting through slots are spaced apart on the limiting plate.

[0016] According to the brushing clamping mechanism provided by this utility model, the second clamping component further includes a second clamping frame, the second clamping frame is rotatably connected to the first clamping component, and the second clamping plate is detachably disposed on the clamping side of the second clamping frame.

[0017] According to the brushing clamping mechanism provided by this utility model, the first clamping component further includes:

[0018] The first clamping frame is rotatably connected to the second clamping assembly;

[0019] The first clamping plate is detachably disposed on the clamping side of the first clamping frame, and the first hollow portion is disposed on the first clamping plate.

[0020] The brushing clamping mechanism provided by this utility model also includes a base, which is rotatably connected to the first clamping component or the second clamping component.

[0021] According to the brush-coating clamping mechanism provided by this utility model, the base includes:

[0022] The substrate has an area greater than the sum of the areas of the first cutout portion and the second cutout portion;

[0023] A boss is disposed on the substrate along the centerline of the substrate and is rotatably connected to one of the first clamping assembly and the second clamping assembly.

[0024] The brushing clamping mechanism provided by this utility model further includes a first support member, which is disposed on at least one of the first clamping assembly and the substrate. When the first clamping assembly and the second clamping assembly are in the unfolded state, the first support member is used to keep the first clamping assembly parallel to the substrate.

[0025] The brushing clamping mechanism provided by this utility model further includes a second support member, which is disposed in at least one of the second clamping assembly and the substrate. When the first clamping assembly and the second clamping assembly are in the unfolded state, the second support member is used to keep the second clamping assembly and the substrate parallel.

[0026] The brush coating clamping mechanism provided by this utility model effectively improves the stability and coating accuracy of the clamped part by using the through-hole design of the first and second hollow parts combined with the positioning function of the limiting groove. The limiting groove can directly constrain the edge of the clamped part through mechanical limiting, effectively solving the problem of displacement or detachment caused by insufficient clamping force. At the same time, the rotating connection design of the dual clamping components simplifies the clamping operation steps, and the through-hole array structure not only ensures uniform coverage of the silicone grease but also "seals" the opening of the limiting groove, preventing the clamped part from falling out of the limiting groove.

[0027] Compared to existing fixtures that can only process single ceramic sheets, the brush coating clamping mechanism provided by this invention solves the technical defect of easy displacement and detachment of ceramic sheets through the mechanical limiting of the limiting through groove and the synergistic effect of the clamping of the first and second hollow parts. Simultaneously, the double hollow structure simultaneously exposes the coating areas on both sides, breaking through the efficiency bottleneck of traditional single-sided sequential processing. Furthermore, the limiting through groove adopts a multi-groove parallel layout, which can simultaneously clamp multiple ceramic sheets for batch coating, effectively improving the processing efficiency per unit time compared to the limitation of existing technologies that process only a single ceramic sheet at a time.

[0043] See Figures 1 to 4 This utility model provides a brushing clamping mechanism for clamping and positioning ceramic insulating sheets when thermally conductive silicone grease is applied to both sides. It should be noted that the brushing clamping mechanism provided in this utility model embodiment is not limited to ceramic sheets, but can also be used for other components that require double-sided brushing, such as aluminum sheets, copper sheets, and other thermally conductive sheets. The specific application can be adapted according to actual needs. This utility model embodiment uses a ceramic sheet as an example for illustration and explanation.

[0044] The brush coating clamping mechanism includes a first clamping component 100 and a second clamping component 200. The main body of the first clamping component 100 is a plate-like structure, and its surface is provided with a first hollow portion 110. The first hollow portion 110 is composed of a plurality of spaced through holes, and the distribution area of ​​the through holes matches the coating area of ​​the workpiece to be clamped—the ceramic sheet. One end of the second clamping component 200 is rotatably connected to one end of the first clamping component 100. The two can rotate around a rotation axis to realize the opening and closing action. The rotatable connection can be achieved by a hinge or a pivot structure.

[0045] The surface of the second clamping component 200 is provided with a second hollow portion 210, the shape, size and distribution of through holes of which correspond to the first hollow portion 110 to ensure that the two hollow portions are aligned during clamping. On the clamping side of the second clamping component 200 (i.e. the side facing the first clamping component 100 when the second clamping component 200 and the first clamping component 100 are closed), a plurality of limiting through grooves 220 are provided at intervals. The depth of the limiting through grooves 220 is slightly greater than (or can be directly set to be equal to) the thickness of the ceramic sheet. For example, if the thickness of the ceramic sheet is 0.8 mm, a limiting through groove 220 with a depth of 0.8 mm can be selected. The limiting through grooves 220 are used to embed into the edge of the ceramic sheet to limit its lateral displacement. The second hollow portion 210 and the limiting through grooves 220 can be integrated on the same plate or can be set separately on the corresponding plate.

[0046] In one optional embodiment, the through holes in the first hollow portion 110 and the second hollow portion 210 are arranged in a rectangular array. The length and width of the bottom of the limiting through groove 220 match the length and width tolerance range of the ceramic sheet. For example, when the standard width of the ceramic sheet is 1mm, the width of the limiting through groove 220 is designed to be 1.05-1.1mm, which allows the ceramic sheet to be smoothly embedded and provides clamping force through slight elastic deformation. In another optional embodiment, a snap-fit ​​structure with a spring can be provided in the limiting through groove 220. The spring is made of flexible metal or plastic. The spring applies pressure to the side of the ceramic sheet to enhance the fixing effect. In this embodiment, the specific size of the limiting through groove 220 is not limited.

[0047] During operation, the second clamping assembly 200 is rotated open around the rotation axis, and the ceramic sheet is placed in the limiting groove of the second clamping assembly 200. Then, the first clamping assembly 100 and the second clamping assembly 200 are closed, so that the ceramic sheet is clamped between the two hollowed-out portions. At this time, the double-sided coated area of ​​the ceramic sheet is fully exposed through the through holes of the first hollowed-out portion 110 and the second hollowed-out portion 210.

[0048] Applying silicone grease to the outside of the first clamping component 100 and the outside of the second clamping component 200 with a scraper can achieve double-sided coating of the ceramic sheet. In another optional operation, the entire clamping mechanism can be immersed in the thermally conductive silicone grease container. The silicone grease penetrates to both sides of the ceramic sheet through the through holes. When the clamping mechanism is lifted upward, the excess silicone grease on both sides of the ceramic sheet is scraped off by the scraper at the top of the container, and finally a uniform coating is formed on the surface of the ceramic sheet.

[0049] It is understandable that the brush coating clamping mechanism provided by this utility model, through the through-hole design of the first hollow part 110 and the second hollow part 210, combined with the positioning function of the limiting groove, effectively improves the stability and coating accuracy of the clamped part. The limiting groove can directly constrain the edge of the clamped part through mechanical limiting, effectively solving the problem of displacement or detachment caused by insufficient clamping force. At the same time, the rotating connection design of the dual clamping components simplifies the clamping operation steps, and the through-hole array structure not only ensures uniform coverage of the silicone grease but also "seals" the opening of the limiting groove, preventing the clamped part from falling out of the limiting groove.

[0050] Compared to existing technologies, the brush coating clamping mechanism provided by this utility model solves the technical defect of easy displacement and detachment of ceramic sheets through the synergistic effect of the mechanical limiting groove 220 and the clamping of the first hollow part 110 and the second hollow part 210. At the same time, the double hollow part structure simultaneously exposes the double-sided coating area, breaking through the efficiency bottleneck of traditional single-sided sequential processing. In addition, the limiting groove 220 adopts a multi-groove parallel layout, which can simultaneously clamp multiple ceramic sheets for batch coating, effectively improving the processing efficiency per unit time compared to the limitation of existing technologies that can only process a single ceramic sheet at a time.

[0051] See Figure 2 and Figure 3 In an optional embodiment of this utility model, the hollow area of ​​the first hollow part 110 is smaller than the hollow area of ​​the second hollow part 210. Specifically, the hollow area can be differentiated by adjusting the number, spacing and diameter of the through holes on the first hollow part 110 and the number, spacing and diameter of the through holes on the second hollow part 210.

[0052] In one specific embodiment, the number and spacing of through holes in the first hollow portion 110 and the second hollow portion 210 are the same, except that the diameter of the through holes in the first hollow portion 110 is smaller than the diameter of the through holes in the second hollow portion 210; in another specific embodiment, the diameter of the through holes in the first hollow portion 110 and the second hollow portion 210 are the same, except that the number of through holes in the second hollow portion 210 is greater than that in the first hollow portion 110, and / or the spacing is smaller than that in the first hollow portion 110.

[0053] It is understood that in the coating clamping mechanism provided in this utility model embodiment, by setting the hollow area of ​​the first hollow part 110 to be smaller than the hollow area of ​​the second hollow part 210, for example by adjusting the number of through holes, the spacing or the difference in hole diameter, the first clamping component 100 and the second clamping component 200 can form a difference in the coating area when applying thermal conductive grease.

[0054] Specifically, when the second clamping component 200 adopts a small mesh window design, its through-holes are more densely distributed or have larger apertures, resulting in a relatively large contact area of ​​the silicone grease on the second clamping component 200 side during the coating process. When the first clamping component 100 adopts a large mesh window design, its through-holes are more sparsely distributed or have smaller apertures, resulting in a relatively small contact area of ​​the silicone grease.

[0055] Because silicone grease has adhesive properties, the difference in contact area will directly result in the second clamping component 200 having a significantly greater adhesion force to the ceramic sheet than the first clamping component 100. Therefore, when the clamping mechanism is opened, the ceramic sheet can automatically remain in the limiting groove 220 of the second clamping component 200 due to the difference in adhesion force, avoiding accidental detachment due to gravity or mechanical vibration, thereby ensuring the positioning stability of the ceramic sheet after coating.

[0056] Compared to prior art solutions that rely solely on mechanical clamping while neglecting the influence of adhesive force balance, this design actively adjusts the difference in the area of ​​the double-sided coating, utilizing the inherent viscosity of the silicone grease to create an asymmetrical adhesive force distribution. This cleverly solves the technical problem of the ceramic sheet easily detaching from the clamping assembly during the opening and closing of the clamping mechanism without adding any additional fixing structures. Simultaneously, since the second clamping assembly 200 already possesses the lateral constraint function of the limiting groove 220, combined with the longitudinal fixing effect formed by the adhesive force difference, the positioning reliability of the ceramic sheet during dynamic operation is further improved.

[0057] Continue reading Figures 2 to 4 In an optional embodiment of the present invention, the first hollow portion 110 includes a plurality of first mesh units 111. The number, position and shape of these first mesh units 111 correspond to the number, position and shape of the limiting through slots 220 on the second clamping component 200. Each first mesh unit 111 is composed of a plurality of spaced through holes.

[0058] Optionally, the second perforated portion 210 may also include a plurality of second mesh units 211, the number, position and shape of which also correspond to the limiting through groove 220. Each second mesh unit 211 is composed of a plurality of spaced through holes. For example, in an optional embodiment, the through holes of the first mesh unit 111 and the second mesh unit 211 are arranged in a rectangular array, and the area covered by each mesh unit is aligned with the ceramic sheet area defined by the limiting through groove 220, ensuring that the coated area of ​​the ceramic sheet is fully exposed through the through holes when clamped.

[0059] In another optional embodiment, the through-hole shape of the mesh unit can be designed as circular, rhomboid, or other geometric shapes, but its distribution density and coverage area still match the position of the limiting through-slot 220, thereby ensuring that the coating area on both sides of the ceramic sheet is uniformly covered after clamping. It should be noted that the spacing between the through-holes in the mesh unit can be adjusted according to the size of the ceramic sheet and the coating thickness requirements. For example, in scenarios requiring a thicker coating, the through-hole spacing can be appropriately reduced to increase the silicone grease contact area, while in thin coating applications, the through-hole spacing can be increased to reduce the amount of silicone grease used.

[0060] During operation, when the first clamping assembly 100 and the second clamping assembly 200 are closed, the through-hole distribution areas of the first mesh unit 111 and the second mesh unit 211 strictly correspond to the positions of the limiting through-hole 220. This allows the edge of the clamped ceramic sheet to be embedded in the limiting through-hole 220, while the coating area is fully exposed through the through-holes. At this time, if thermal grease is applied by scraping or dipping, the grease can evenly cover both sides of the ceramic sheet through the through-holes. For example, when using the scraping method, the scraper moves along the outer surface of the clamping assembly, and the grease penetrates into the surface of the ceramic sheet through the through-holes of the mesh unit. The spacing of the through-holes can prevent local accumulation or absence of grease, ensuring a consistent coating thickness.

[0061] If the dip coating method is used, after the clamping mechanism is fully immersed in the silicone grease container, the silicone grease penetrates to both sides of the ceramic sheet through the through holes. When the lifting mechanism is used, the scraper on the top of the container will scrape off the excess silicone grease. The regular arrangement of the through holes can reduce fluid resistance and avoid coating defects caused by uneven silicone grease flow.

[0062] It is understood that in the coating clamping mechanism provided in this utility model embodiment, by decomposing the first hollow part 110 and the second hollow part 210 into mesh units corresponding to the limiting through groove 220, and configuring each mesh unit to be composed of spaced through holes, the clamping mechanism can accurately limit the coating area of ​​the ceramic sheet when closed, and at the same time optimize the flow path and coverage uniformity of the silicone grease through the regular arrangement of the through holes.

[0063] Compared to designs using only a single hollow area, the coating clamping mechanism provided in this embodiment achieves coordinated matching between the coating area and the limiting structure through a modular layout of mesh units. This enhances both clamping and positioning accuracy and improves coating efficiency. Specifically, in batch processing scenarios, multiple ceramic sheets can be simultaneously embedded in the limiting slot 220, and the coating area of ​​each ceramic sheet is independently exposed through its corresponding mesh unit, avoiding mutual interference and thus solving the efficiency bottleneck of traditional single-sheet processing.

[0064] Continue reading Figure 1In an optional embodiment of this utility model, the second clamping assembly 200 includes a second clamping plate 230 and a limiting plate 240. One end of the second clamping plate 230 is rotatably connected to one end of the first clamping assembly 100 via a rotating shaft or hinge structure. A second hollow portion 210 is provided on the plate body of the second clamping plate 230, which is composed of an array of multiple through holes.

[0065] The limiting plate 240 is detachably fixed to the clamping side of the second clamping plate 230 (i.e., the side facing the first clamping assembly 100 when the second clamping assembly 200 and the first clamping assembly 100 are closed). Multiple limiting slots 220 are spaced apart on the surface of the limiting plate 240, and the dimensions of the limiting slots 220 match the thickness and width tolerances of the ceramic sheet edge. For example, in one optional embodiment, the limiting plate 240 is fixed to the second clamping plate 230 by screws or snap-fit ​​structures. In another optional embodiment, the limiting plate 240 can be designed as a multi-segment structure, with each segment independently installed in a different area of ​​the second clamping plate 230. The spacing or number of limiting slots 220 on each segment of the limiting plate 240 can be flexibly adjusted according to the size or arrangement requirements of the ceramic sheet.

[0066] During use, the operator first installs the limiting plate 240 on the clamping side of the second clamping plate 230 using screws or clips, ensuring that the position of the limiting through groove 220 corresponds to the through hole array of the second hollow portion 210. Subsequently, the second clamping assembly 200 is rotated open around the pivot, and the ceramic pieces are inserted one by one into the limiting through groove 220 of the limiting plate 240. After closing the first clamping assembly 100 and the second clamping assembly 200, the coated area of ​​the ceramic piece is fully exposed through the second hollow portion 210 of the second clamping plate 230 and the first hollow portion 110 of the first clamping assembly 100.

[0067] It is understood that in the coating clamping mechanism provided in this embodiment of the present invention, the modularity and scalability of the clamping mechanism are achieved by designing the limiting plate 240 as a detachable structure and separating it from the second clamping plate 230.

[0068] Compared to fixed clamping components, the independent replacement function of the limiting plate 240 allows the same clamping mechanism to quickly adapt to ceramic sheets of different sizes or quantities, effectively improving the versatility of the equipment. For example, when multiple small ceramic sheets need to be processed in batches, synchronous clamping can be achieved by replacing the limiting plate 240 with multiple rows of limiting slots 220, whereas traditional solutions are limited by fixed limiting structures and are difficult to adjust flexibly.

[0069] Furthermore, the separate design of the limiting plate 240 and the second clamping plate 230 avoids the problem of the entire component being scrapped due to wear of the limiting groove 220 in the integrated structure, thus reducing maintenance costs. At the same time, the second hollow part 210 on the second clamping plate 230 and the limiting groove 220 of the limiting plate 240 achieve functional decoupling through independent design. This ensures accurate exposure of the coating area while suppressing ceramic sheet displacement through the mechanical limiting function of the limiting plate 240, thereby simplifying the structure while taking into account clamping stability and operational flexibility.

[0070] Figure 5 This is a schematic diagram of the structure of the second clamping frame provided in an embodiment of the present invention.

[0071] See Figure 1 and Figure 5 In an optional embodiment of this utility model, the second clamping assembly 200 includes a second clamping frame 250. One end of the second clamping frame 250 is rotatably connected to the first clamping assembly 100 via a pivot or hinge structure, allowing the second clamping frame 250 to rotate and open relative to the first clamping assembly 100. A second clamping plate 230 is detachably mounted on the clamping side of the second clamping frame 250 (i.e., the side facing the first clamping assembly 100 when the second clamping assembly 200 and the first clamping assembly 100 are closed). The surface of the second clamping plate 230 is provided with a second hollow portion 210, the array of which corresponds to the coating area. In other words, one end of the second clamping plate 230 is indirectly rotatably connected to one end of the first clamping assembly 100 via the second clamping frame 250.

[0072] For example, in one alternative embodiment, the second clamping frame 250 is made of metal or high-strength plastic, and its clamping side is provided with a slide rail or slot structure. The second clamping plate 230 is connected to the second clamping frame 250 by sliding insertion or snap-fit ​​fixing. In another alternative embodiment, the second clamping plate 230 can be fixed to the second clamping frame 250 by screws or magnetic attraction, facilitating quick disassembly and replacement. Furthermore, the separate design of the second clamping frame 250 and the second clamping plate 230 allows for flexible configuration of the clamping plate type according to different coating requirements. For example, when different sized ceramic sheets need to be clamped, only the appropriate second clamping plate 230 needs to be replaced, without adjusting or replacing the entire second clamping frame 250.

[0073] During assembly, the operator first installs the second clamping plate 230 onto the clamping side of the second clamping frame 250, ensuring that the cutout portion of the second clamping plate 230 aligns with the cutout portion of the first clamping assembly 100 when closed. Then, the ceramic sheet is placed within the limiting slot 220 of the limiting plate 240, and the second clamping assembly 200 and the first clamping assembly 100 are closed, allowing the coated area of ​​the ceramic sheet to be fully exposed through the cutout portion. When processing ceramic sheets of different sizes, the operator can remove the current second clamping plate 230 and limiting plate 240 from the frame and replace them with a second clamping plate 230 and limiting plate 240 having matching cutout portions and limiting slots 220, while the main structure of the second clamping frame 250 remains unchanged.

[0074] During the coating process, whether the clamping mechanism is fully immersed in the silicone grease container or the silicone grease is applied by scraping, the rigid structure of the second clamping frame 250 provides stable support, preventing uneven coating caused by deformation of the clamping plate under stress. After coating, the second clamping plate 230 can be disassembled for separate cleaning or maintenance, reducing wear and tear on the frame body due to silicone grease residue. Furthermore, when applying silicone grease by scraping, the side of the second clamping frame 250 away from the second clamping plate 230 can form a cavity for containing silicone grease, allowing it to be directly introduced and scraped back and forth along the edge of the second clamping frame 250 with a scraper.

[0075] It is understood that the coating clamping mechanism provided in this embodiment of the present invention improves the modularity and maintainability of the clamping mechanism by introducing a split design of the second clamping frame 250 and the second clamping plate 230.

[0076] Compared to fixed clamping components, the second clamping frame 250, as a basic support structure, can accommodate various specifications of the second clamping plate 230, thereby expanding the equipment's compatibility with ceramic sheets of different sizes. For example, in production scenarios that require frequent switching of ceramic sheet types, configuration adjustments can be quickly completed simply by replacing the second clamping plate 230 and the limiting plate 240, without requiring downtime to modify the main frame, effectively reducing equipment changeover time.

[0077] Furthermore, the rigid structure of the second clamping frame 250 enhances overall clamping stability, preventing ceramic sheet displacement or coating defects caused by deformation of the second clamping plate 230 during the coating process. Simultaneously, the independent disassembly design of the second clamping plate 230 and the limiting plate 240 simplifies cleaning and maintenance procedures, extends the service life of the frame body, and reduces long-term operating costs.

[0079] See Figure 1 , Figure 6 and Figure 7 In an optional embodiment of this utility model, the first clamping assembly 100 includes a first clamping frame 120 and a first clamping plate 130. One end of the first clamping frame 120 is rotatably connected to the second clamping frame 250 in the second clamping assembly 200 via a pivot or hinge structure, so that the first clamping frame 120 can rotate around the pivot to open and close the clamping mechanism.

[0080] The first clamping plate 130 is detachably installed on the clamping side of the first clamping frame 120 (i.e., the side facing the second clamping assembly 200 when the first clamping assembly 100 and the second clamping assembly 200 are closed). The plate body of the first clamping plate 130 is provided with a first hollow portion 110, which is composed of an array of multiple through holes. The distribution of the through holes corresponds to the coating area of ​​the ceramic sheet.

[0081] For example, in one optional embodiment, the clamping side of the first clamping frame 120 is provided with a snap-fit ​​or slide rail structure, and the first clamping plate 130 is fixed to the first clamping frame 120 by sliding insertion or snap-fit, facilitating quick assembly and disassembly. In another optional embodiment, the first clamping plate 130 can be connected to the first clamping frame 120 by screws or magnetic attraction to adapt to the requirements of clamping plates of different thicknesses or materials. In addition, the separate design of the first clamping frame 120 and the first clamping plate 130 allows for flexible replacement of the first clamping plate 130 according to the coating process requirements. For example, when it is necessary to adjust the density or distribution of through holes, only the first clamping plate 130 needs to be replaced without modifying the frame body.

[0082] During operation, the operator first installs the first clamping plate 130 onto the clamping side of the first clamping frame 120, ensuring that the cutout portion of the first clamping plate 130 is aligned with the cutout portion of the second clamping assembly 200 in the closed state. Then, the first clamping assembly 100 and the second clamping assembly 200 are closed, clamping the ceramic sheet between them, with its coated area fully exposed through the cutout portions on both sides. When processing ceramic sheets of different sizes, the operator can disassemble the current first clamping plate 130 and replace it with a new first clamping plate 130 with an adapted cutout portion, while the rotating connection structure of the first clamping frame 120 remains unchanged.

[0083] During the coating process, whether using a scraping or dipping method, the rigid structure of the first clamping frame 120 provides stable support for the first clamping plate 130, preventing deformation or displacement caused by external forces and ensuring that the coating area is always accurately exposed. After coating, the first clamping plate 130 can be removed to clean residual silicone grease or perform maintenance, reducing wear and tear on the frame body caused by prolonged contact with silicone grease. In addition, when applying silicone grease by scraping, the side of the first clamping frame 120 away from the first clamping plate 130 can form a cavity for containing silicone grease, where the silicone grease can be directly introduced and scraped back and forth along the edge of the first clamping frame 120 with a scraper.

[0084] It is understood that in the brushing clamping mechanism provided in this embodiment of the present invention, by decomposing the first clamping component 100 into a detachable first clamping plate 130 and a fixedly supported first clamping frame 120, the modularity and ease of maintenance of the clamping mechanism are enhanced.

[0085] Compared to the integrated clamping structure, the independent design of the first clamping plate 130 allows the through-hole layout of the coating area to be flexibly adjusted according to needs. For example, when it is necessary to adapt to different ceramic sheet sizes or coating thicknesses, only the first clamping plate 130 needs to be replaced to complete the configuration update, without the need to replace the entire first clamping assembly 100, which effectively reduces the equipment modification cost.

[0086] Meanwhile, the rigid structure of the first clamping frame 120 ensures stability during the clamping process, preventing ceramic sheet displacement or coating defects caused by uneven force on the first clamping plate 130. Furthermore, the quick-release function of the first clamping plate 130 simplifies the cleaning and maintenance process, extending the service life of the first clamping frame 120.

[0087] Continue reading Figure 1 , Figure 5 , Figure 6 and Figure 7 In an optional embodiment of the present invention, the brushing clamping mechanism further includes a base 300, which is rotatably connected to the first clamping component 100 or the second clamping component 200 via a rotating shaft or hinge structure.

[0088] For example, in one alternative embodiment, the base 300 is fixed to the workbench surface, and one side of it is connected to the bottom of the first clamping frame 120 via a hinge, allowing the first clamping assembly 100 to rotate and open around the base 300, while the second clamping assembly 200 moves synchronously with the rotation of the first clamping assembly 100. In another alternative embodiment, the base 300 is connected to the side of the second clamping frame 250 via a pivot, allowing the entire clamping mechanism to rotate relative to the base 300 to adjust its angle.

[0089] During operation, the base 300 serves as a fixed or adjustable reference for the clamping mechanism. Its rotatable connection with the first or second clamping assembly 200 enables controllable opening and closing of the clamping mechanism. For example, when the base 300 is fixed to the workbench and connected to the first clamping assembly 100, the operator can rotate the first clamping assembly 100 to open or close it relative to the base 300, thus facilitating the placement or removal of ceramic sheets. In the case of direct scraping with a scraper, the orientation of the first clamping assembly 100 and the second clamping assembly 200 relative to the base 300 can be sequentially flipped so that the side of the first clamping assembly 100 away from the second clamping assembly 200 or the side of the second clamping assembly 200 away from the first clamping assembly 100 is convenient for the operator to scrape.

[0090] It is understood that in the coating clamping mechanism provided in this embodiment of the present invention, by introducing a base 300 and rotating it with the first or second clamping component 200, a stable operating reference is provided for the clamping mechanism, which effectively suppresses the shaking of the mechanism caused by manual operation or external interference during the coating process.

[0091] Compared to hand-held solutions, the rigid support and angle adjustment of the base 300 effectively improve the operational stability and coating consistency of the clamping mechanism. For example, when directly coating with a scraper, the base 300 provides favorable support for the operator, allowing the operator to complete the coating of the ceramic sheet with only one hand, which improves the convenience of operation and the stability of the process.

[0092] Continue reading Figure 1 and Figure 5 In an optional embodiment of this utility model, the base 300 includes a substrate 310 and a boss 320. The area of ​​the substrate 310 is designed to be greater than the sum of the areas of the first cutout portion 110 and the second cutout portion 210, so as to provide a stable support reference. The boss 320 is disposed along the centerline region of the substrate 310 and is rotatably connected to the first clamping assembly 100 or the second clamping assembly 200 via a pivot or hinge structure.

[0093] For example, in one alternative embodiment, the substrate 310 is a rectangular metal plate, the length and width of which both exceed the projected size of the clamping assembly in the open state. The boss 320 is welded or bolted to the center line of the substrate 310, and its top is provided with a pivot hole for hinged connection with the end of the first clamping frame 120 or the second clamping frame 250.

[0094] In another alternative embodiment, the boss 320 is detachably mounted to the centerline of the substrate 310 by screws, facilitating adjustment of the boss 320's position according to the size of the clamping assembly. Furthermore, the boss 320 can be designed in a cylindrical, prismatic, or other geometric shape, with its height set according to the rotation radius requirements of the clamping assembly to ensure smooth movement trajectory during opening and closing of the clamping mechanism.

[0095] During assembly, the operator fixes the boss 320 to the centerline of the substrate 310 and connects the end of the clamping assembly (first clamping assembly 100 or second clamping assembly 200) to the boss 320 via a pivot. When the substrate 310 is fixed to the worktable, the clamping mechanism can rotate and open around the pivot on the boss 320. The large area design of the substrate 310 ensures that the mechanism remains stable during the coating process.

[0096] When applying coating directly with a scraper, the operator can flip the first clamping component 100 and the second clamping component 200 together to either side of the center line of the substrate 310. This allows the side of the first cutout portion 110 away from the second clamping component 200 or the side of the second cutout portion 210 away from the first clamping component 100 to face the operator, thus facilitating the operator's coating application.

[0097] It is understood that in the brushing clamping mechanism provided in this embodiment of the present invention, by decomposing the base 300 into a combination structure of a substrate 310 and a boss 320, and limiting the area of ​​the substrate 310 to be greater than the total area of ​​the first hollow part 110 and the second hollow part 210, the overall stability and anti-interference ability of the clamping mechanism are effectively improved.

[0098] Compared to handheld solutions, the large-area contact design of the substrate 310 disperses the force on the mechanism, preventing the table from sliding or tipping over due to localized pressure concentration. The structure of the boss 320, which is positioned along the centerline of the substrate 310, optimizes the rotation center position of the clamping assembly, resulting in a more balanced torque distribution during opening and closing, reducing operating resistance and extending the life of the pivot.

[0099] Continue reading Figure 1 In an optional embodiment of this utility model, the brushing clamping mechanism further includes a first support member 400, which is disposed in at least one of the first clamping assembly 100 and the substrate 310. When the first clamping assembly 100 and the second clamping assembly 200 are deployed to the working state, the first support member 400 is used to maintain the parallel relationship between the first clamping assembly 100 and the substrate 310.

[0100] For example, in one alternative embodiment, the first support member 400 is a telescopic rod structure, one end of which is hinged to the edge region of the substrate 310, and the other end is fixed to the side of the first clamping frame 120 by a snap fastener. When the clamping assembly is unfolded, the telescopic rod extends to a preset length to limit the rotation angle of the first clamping assembly 100, thereby ensuring that it is parallel to the substrate 310. The first support member 400 can also be a rod directly mounted on the substrate 310 or the first clamping assembly 100, which can be adapted according to actual needs.

[0101] In another alternative embodiment, the first support member 400 is a foldable support plate, which is mounted on the surface of the substrate 310 via a pivot. When the clamping assembly is unfolded, the support plate rotates to a vertical position and abuts against the back of the first clamping assembly 100, forcibly maintaining parallelism through mechanical limiting. It should be noted that the mounting position of the first support member 400 can be adjusted according to requirements. For example, when it is necessary to adapt to clamping assemblies of different sizes, the support member can be designed as a slide rail structure, sliding along the edge of the substrate 310 to the appropriate position and then locking.

[0102] During operation, when the first clamping assembly 100 and the second clamping assembly 200 are unfolded to the coating state, the first support member 400 restricts the rotational freedom of the first clamping assembly 100 through physical limiting or rigid support. For example, when a telescopic rod support member is used, after the operator unfolds the clamping assembly to a preset angle, the telescopic rod extends to a fixed length. At this time, the first clamping assembly 100 cannot continue to rotate due to the rod length limitation, thus remaining parallel to the substrate 310. If a folding support plate is used, the operator manually rotates the support plate to a vertical state, so that its top surface contacts the back of the first clamping assembly 100, and parallelism is maintained by friction or locking through a slot.

[0103] It is understood that in the brush coating clamping mechanism provided in this embodiment of the present invention, by introducing the first support member 400 and forcibly limiting the parallel relationship between the first clamping component 100 and the substrate 310, the stability of the clamping mechanism during the coating process is effectively improved.

[0104] Compared to solutions requiring manual adjustment or lacking a fixed reference, the rigid limiting function of the support member eliminates tilting of the clamping assembly caused by operational errors or external force interference, ensuring the repeatability and accuracy of the coating process. For example, in the case of direct scraping with a scraper, the first support member 400 ensures that the first cutout portion 110 is in a horizontal state, which facilitates scraping by the operator and ensures uniformity during the scraping process. In addition, in mass production, the parallel first clamping assembly 100 ensures consistent immersion depth each time, avoiding coating thickness fluctuations caused by angular deviations.

[0105] Continue reading Figure 1In an optional embodiment of this utility model, the brushing clamping mechanism further includes a second support member 500, which is disposed in at least one of the second clamping assembly 200 and the substrate 310. When the first clamping assembly 100 and the second clamping assembly 200 are deployed to the working state, the second support member 500 is used to maintain the parallel relationship between the second clamping assembly 200 and the substrate 310.

[0106] For example, in one alternative embodiment, the second support member 500 is a telescopic rod structure, one end of which is connected to the edge area of ​​the substrate 310 by a hinge, and the other end is fixed to the side of the second clamping frame 250 by a snap fastener. When the clamping assembly is unfolded, the telescopic rod extends to a preset length to limit the rotation angle of the second clamping assembly 200, thereby ensuring that it is parallel to the substrate 310.

[0107] In another alternative embodiment, the second support 500 is a foldable metal bracket mounted on the surface of the substrate 310 via a pivot. When the clamping assembly is unfolded, the bracket rotates to a vertical position and abuts against the back of the second clamping assembly 200, maintaining parallelism through rigid contact. It should be noted that the mounting position of the second support 500 can be adjusted as needed. For example, when it is necessary to adapt to clamping assemblies of different sizes, the support can be designed as a sliding rail structure, sliding along the edge of the substrate 310 to the appropriate position and then locking.

[0108] During operation, when the first clamping assembly 100 and the second clamping assembly 200 are unfolded to the coating state, the second support member 500 restricts the rotational freedom of the second clamping assembly 200 through physical limiting or rigid support. For example, when a telescopic rod support member is used, after the operator unfolds the clamping assembly to a preset angle, the telescopic rod extends to a fixed length. At this time, the second clamping assembly 200 cannot continue to rotate due to the rod length limitation, thus remaining parallel to the substrate 310. If a folding metal bracket is used, the operator manually rotates the metal bracket to a vertical state, so that its top surface contacts the back of the first clamping assembly 100, and parallelism is maintained by friction or locking through a slot.

[0109] It is understood that in the brush coating clamping mechanism provided in this embodiment of the present invention, by introducing the second support member 500 and forcibly limiting the parallel relationship between the second clamping component 200 and the substrate 310, the stability of the clamping mechanism during the coating process is effectively improved.

[0110] Compared to solutions requiring manual adjustment or lacking a fixed reference, the rigid limiting function of the second support 500 eliminates tilting of the clamping assembly caused by operational errors or external force interference, ensuring the repeatability of the coating process. For example, in the case of direct scraping with a scraper, the second support 500 ensures that the second cutout 210 is in a horizontal state, which facilitates scraping by the operator and ensures uniformity during the scraping process. Furthermore, in mass production, the parallel second clamping assembly 200 ensures consistent immersion depth each time, avoiding coating thickness fluctuations caused by angular deviations.

[0111] The following illustrates a specific optional implementation method of the brush clamping mechanism provided in this utility model embodiment.

[0112] Ceramic sheet positioning: The ceramic sheet is embedded in the limiting groove 220 of the limiting plate 240 of the second clamping assembly 200, and the lateral constraint is achieved by matching the dimensional tolerance between the limiting groove 220 and the edge of the ceramic sheet.

[0113] Clamping closure: Rotate the first clamping component 100 to close it with the second clamping component 200, and lock the position of both by the locking structure to ensure that the ceramic sheet is clamped between the first clamping plate 130 and the second clamping plate 230.

[0114] First flip and coating: Rotate the entire clamping mechanism 180 degrees around the base 300 pivot so that the outer side of the second clamping assembly 200 faces upward. At this time, the second cutout portion 210 of the second clamping plate 230 is fully exposed to the coating area on the lower surface of the ceramic sheet. Apply thermal grease to the lower surface of the ceramic sheet through the through hole of the second cutout portion 210 using a scraper.

[0115] Secondary flipping and coating: Rotate the clamping mechanism 180 degrees again to reset it, so that the outer side of the first clamping assembly 100 faces upward, and the first hollow part 110 of the first clamping plate 130 exposes the coating area on the upper surface of the ceramic sheet. Repeat the coating operation to complete the brushing of the upper surface with silicone grease.

[0116] Adhesion control: Based on the difference in the distribution of through holes between the first hollow part 110 and the second hollow part 210, the silicone grease contact area on the side of the second clamping component 200 is larger, forming an asymmetric adhesion force, ensuring that the ceramic sheet remains in the limiting through groove 220 of the second clamping component 200 when opening and closing.

[0117] Ceramic sheet removal: Unlock and rotate to open the first clamping assembly 100. Use a tool to remove the coated ceramic sheet from the limiting groove 220 of the second clamping assembly 200 and place it in the preset position.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
