Description

Technical Field

[0001] This utility model relates to the field of powder coating tooling technology, specifically, to a powder coating tooling for alumina ceramic blanks. Background Technology

[0002] In the preparation of alumina ceramic blanks, powder coating is a crucial step. Its purpose is to uniformly deposit a layer of alumina ceramic powder onto the substrate, laying the foundation for subsequent pressing, sintering, and other processes. Traditional powder coating fixtures have the following problems.

[0003] Existing powder coating fixtures mostly use manual or simple scraper application, making it difficult to precisely control the powder thickness. This can easily lead to localized accumulation or thinning, resulting in uneven density of the ceramic wafers and affecting the mechanical and dielectric properties of the ceramic products. Furthermore, the substrate is prone to displacement during the powder coating process, causing the powder coating area to deviate from the design position and affecting the dimensional accuracy and consistency of the wafers. Therefore, a powder coating fixture for alumina ceramic wafers is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a powder coating fixture for alumina ceramic blanks, which solves the problems in the prior art where powder coating is mostly done manually or with a simple scraper, making it difficult to accurately control the powder thickness, easily leading to local accumulation or thinning, resulting in uneven density of the blanks, affecting the mechanical and dielectric properties of the ceramic products, and the substrate is prone to displacement during the powder coating process, causing the powder coating area to deviate from the design position, affecting the dimensional accuracy and consistency of the blanks.

[0005] This utility model provides the following technical solution: a powder-coating fixture for alumina ceramic blanks, including a processing table, a support fixedly connected to the top of the processing table, a pressing component at the top of the support, a connecting component at the top of the processing table, four sets of clamping components for fixing the ceramic blanks around the connecting component, and a rotating component at the bottom of the processing table.

[0006] As a preferred embodiment of the above technical solution, the pressing component includes a cylinder, which is fixedly installed on the top of the bracket. A mounting plate is installed on the telescopic end of the cylinder, and a pressing plate is installed on the bottom end of the mounting plate by bolts.

[0007] As a preferred embodiment of the above technical solution, the connecting assembly includes a top plate, a support frame is fixedly connected to the bottom end of the top plate, a plurality of sliding grooves are provided at the bottom end of the support frame, and the bottom end of the support frame is fixedly connected to the top of the processing table.

[0008] As a preferred embodiment of the above technical solution, the support frame is cross-shaped and the slide groove is T-shaped.

[0009] As a preferred embodiment of the above technical solution, the clamping assembly includes a slider, the bottom end of which is fixedly connected to a plug rod, and the side end of the slider is fitted with a clamping plate by bolts.

[0010] As a preferred embodiment of the above technical solution, the slider is T-shaped and is slidably connected within the groove.

[0011] As a preferred embodiment of the above technical solution, the rotating assembly includes a motor, which is fixedly installed at the bottom of the processing table. A rotating rod is installed at the output end of the motor, and the rotating rod is inserted into the top of the processing table. A circular plate is fixedly connected to the top of the rotating rod, and a plurality of oblique arc-shaped grooves are formed on the circumference of the top of the circular plate. The rotating rod is inserted into the oblique arc-shaped grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a rotating component, a connecting component, and a clamping component to clamp the substrate. After a certain amount of alumina ceramic powder is placed on the top of the substrate, the ceramic powder is leveled by a scraper, and the ceramic powder on the top of the substrate is pressed flat by a pressing component. This ensures that the thickness of the ceramic powder on the substrate is uniform and precisely controlled, avoiding local accumulation or thinning of the ceramic powder on the top of the substrate.

Furthermore, by clamping the substrate around its perimeter, the invention prevents displacement of the substrate during the powder application process, thus preventing the powder application area from deviating from the designed position and affecting the dimensional accuracy and consistency of the ceramic sheet.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a powder-coating fixture for alumina ceramic blanks, including a processing table 1, a support 101 fixedly connected to the top of the processing table 1, a pressing component 2 at the top of the support 101, a connecting component 3 at the top of the processing table 1, four sets of clamping components 4 for fixing the ceramic blanks around the connecting component 3, and a rotating component 5 at the bottom of the processing table 1. The substrate is clamped by the cooperation of the rotating component 5, the connecting component 3, and the clamping components 4. After a certain amount of alumina ceramic powder is placed on the top of the substrate, the ceramic powder is scraped flat by a scraper, and the ceramic powder on the top of the substrate is squeezed and flattened by the pressing component 2, so that the thickness of the ceramic powder on the substrate is uniform and precisely controlled, avoiding local accumulation or thinning of the ceramic powder on the top of the substrate, thereby avoiding uneven density of the blanks and affecting the mechanical and dielectric properties of the ceramic products. Furthermore, after the substrate is clamped around the perimeter by the clamping components 4, the substrate is prevented from shifting during the powder coating process, thereby preventing the powder coating area from deviating from the design position and affecting the dimensional accuracy and consistency of the blanks.

[0021] As one implementation method in this embodiment, such as Figure 1 As shown, the pressing component 2 includes a cylinder 201, which is fixedly installed on the top of the bracket 101. The telescopic end of the cylinder 201 is equipped with a mounting plate 202, and the bottom end of the mounting plate 202 is bolted with a pressing plate 203. In practice, the substrate is clamped by the cooperation of the rotating component 5, the connecting component 3, and the clamping component 4. After a certain amount of alumina ceramic powder is placed on the top of the substrate, the ceramic powder is scraped flat by a scraper. The cylinder 201 is started to drive the pressing plate 203 to move down. The pressing plate 203 enters the clamping plate 403 to press and flatten the ceramic powder on the top of the substrate, thereby making the thickness of the ceramic powder on the substrate uniform and precisely controlled, avoiding local accumulation or thinning of the ceramic powder on the top of the substrate, thus avoiding uneven density of the wafer and affecting the mechanical and dielectric properties of the ceramic product.

[0022] As one implementation method in this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting assembly 3 includes a top plate 301, with a support frame 302 fixedly connected to the bottom end of the top plate 301. The bottom end of the support frame 302 has several sliding grooves 303. The bottom end of the support frame 302 is fixedly connected to the top of the processing table 1. The support frame 302 has a cross-shaped shape, and the sliding grooves 303 have a T-shaped shape. The clamping assembly 4 includes a slider 401, with a rod 402 fixedly connected to the bottom end of the slider 401. The side end of the slider 401 is connected by bolts. The clamping plate 403 is installed, and the bolts facilitate the replacement of the clamping plate 403 with a suitable base plate size. The slider 401 has a T-shaped design and is slidably connected in the slide groove 303. The rotating assembly 5 includes a motor 501, which is fixedly installed at the bottom of the processing table 1. A rotating rod 502 is installed at the output end of the motor 501 and inserted into the top of the processing table 1. A circular plate 503 is fixedly connected to the top of the rotating rod 502. The top circumference of the circular plate 503 is... Several oblique arc-shaped grooves 504 are provided, and the insert rods 402 are inserted into the oblique arc-shaped grooves 504. In practice, after the substrate is placed on the top plate 301, the motor 501 is started to drive the rotating rod 502 and the circular plate 503 to rotate. Since each insert rod 402 is inserted into each oblique arc-shaped groove 504, when the circular plate 503 rotates, the oblique arc-shaped grooves 504 can change position due to the rotation of the circular plate 503. As the position of the oblique arc-shaped grooves 504 gradually changes due to rotation, it pushes the insert rods 402 inside to move. The insert rods 402 can drive the slider 401 to move horizontally in the slide groove 303. At this time, the slider 401 drives the clamping plate 403 to move towards the substrate until each clamping plate 403 clamps the substrate and stops the rotation of the circular plate 503. After the clamping plate 403 clamps the substrate around its perimeter, it prevents the substrate from shifting during the powder coating process, thereby preventing the powder coating area from deviating from the design position and affecting the dimensional accuracy and consistency of the wafer.

[0023] Working principle: After placing the substrate on the top plate 301, the clamping plates 403 of suitable substrate size are replaced and each clamping plate 403 is fixed to the side of each slider 401 with bolts. Then, the pressing plate 203 adapted to the substrate is replaced and fixed to the bottom of the mounting plate 202 with bolts. At this time, the motor 501 is started to drive the rotating rod 502 and the circular plate 503 to rotate. Since each inserting rod 402 is inserted into each inclined arc groove 504, when the circular plate 503 rotates, the position of the inclined arc groove 504 changes due to the rotation of the circular plate 503. As the position of the inclined arc groove 504 gradually changes due to the rotation, it pushes the inserting rod 402 inside to move. The inserting rod 402 can drive the slider 401 to move horizontally within the sliding groove 303. At this time, the slider 401 drives the clamping plate 403 to move towards the substrate (conversely, it can drive the clamping plate 403 away from the side of the substrate) until each clamping plate 403 clamps the substrate and the rotation of the circular plate 503 stops. Figure 1 and Figure 2 (This is a schematic diagram of clamping plate 403 holding the substrate close to it.) At this time, a certain amount of alumina ceramic powder is placed on the top of the clamped substrate. After the ceramic powder is leveled by a scraper, cylinder 201 is activated to drive extrusion plate 203 to move down. Extrusion plate 203 enters the clamping plate 403 to extrude and flatten the ceramic powder on the top of the substrate, thereby ensuring that the thickness of the ceramic powder on the substrate is uniform and precisely controlled. This avoids local accumulation or thinning of the ceramic powder on the top of the substrate, thus preventing uneven density of the preform and affecting the mechanical and dielectric properties of the ceramic product. Furthermore, by clamping the substrate around its perimeter with clamping plate 403, displacement of the substrate is prevented during the powder application process, thus preventing the powder application area from deviating from the design position and affecting the dimensional accuracy and consistency of the preform.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
