Description

Technical Field

[0001] This utility model relates to the field of ceramic slurry processing technology, specifically to a capacitor ceramic slurry processing equipment. Background Technology

[0002] Currently, ceramic capacitors have become indispensable components in electronic circuits due to their core advantages such as high stability, high-frequency characteristics, high voltage resistance, small size, and large capacitance. They are mainly used in various circuits such as DC blocking, bypass / decoupling, coupling, and filtering. In addition to basic functions, they can also cover high-voltage, high-frequency, and precision applications.

[0003] In some related technologies, ceramic capacitors are formed by casting and stacking. After sintering, the capacitors have the advantage of micro-size, which is very conducive to surface mount installation. Therefore, the ceramic paste required for the capacitor can be uniformly coated on the substrate. Therefore, in related technologies, due to the requirements of stacking thickness and capacitor performance, the preparation of ceramic capacitor paste needs to be uniform and fine.

[0004] In other related technologies, the preparation of ceramic capacitor slurry mainly involves fully mixing and stirring ball-milled ceramic powder with solvents and dispersants. Existing mixing operations are mainly based on mixing tanks, with materials being added in a centralized manner. This not only results in low mixing efficiency but also easily leads to uneven mixing.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5 This utility model provides an implementation scheme: First, regarding the capacitor ceramic slurry processing equipment disclosed in this application, its application scenario is explained: The processing equipment disclosed in this application is mainly used in the mixing process of ceramic slurry used in capacitors.

[0037] Specifically, in the modern ceramic capacitor production process, the ceramic slurry needs to be thoroughly stirred and mixed so that it can be evenly coated on the substrate. Then, it is stacked, cut, and shaped. In some related technologies, the mixing equipment for the slurry mainly uses an auger for mixing. This mixing method requires the material to be placed in a container. However, in the current mixing process, the material is usually directly added to the container and then stirred by a stirring device. However, this results in low material mixing efficiency and poor material mixing effect.

[0038] To address the aforementioned issues, this application discloses a capacitor ceramic slurry processing device, comprising a support 1, a mixing tank 2 placed on the support 1, and a mixing component 3 slidably assembled on the support 1. The support 1 serves as the main supporting structure of the device, supporting the mixing tank 2 and slidably assembling the mixing component 3.

[0039] First aspect: Please refer to Figure 1 The aforementioned mixing component 3 includes: a support base 31, a first drive motor 32, a mixer 33, a fabric spreader 34, and a transmission component 35.

[0040] Specifically, the support base 31 is slidably mounted on the bracket 1 and slides along a first direction, which is perpendicular to the horizontal and parallel to the axis of the mixing tank 2. The mixer 33 is inserted into the mixing tank 2 for mixing materials by sliding the support base 31 along the first direction. A first drive motor 32 is located on the support base 31, and the mixer 33 is connected to the first drive motor 32. The first drive motor 32 drives the mixer 33 to stir and mix the materials in the mixing tank 2.

[0041] The support base 31 serves as the main mounting body for the processing equipment. For example, the bracket 1 includes a base 11 and a guide rail 12. The mixing tank 2 is placed on the base 11, and a retainer 13 is provided on the base 11 to limit the mixing tank 2 and ensure the stability of the mixing tank 2. The guide rail 12 is assembled on the base 11, and the guide rail 12 can slide and cooperate with the support base 31 in a first direction, so that the guide rail 12 can limit and guide the support base 31.

[0042] Please see Figure 2 and Figure 3 A feeder 34, mounted on a support base 31, is used to add powder and liquid materials into the mixing tank 2. A transmission assembly 35 drives the mixer 33 and the feeder 34 to work together. For example, the feeder 34 adds materials into the mixing tank 2; some ceramic powder can be pre-added, while the rest is added via the feeder 34. The transmission assembly 35 transmits power from the mixer 33 to the feeder 34, ensuring that the feeder 34 works in sync with the mixer 33.

[0043] In summary, this capacitor ceramic slurry processing equipment allows the mixer 33 to be precisely inserted into the mixing tank 2 via the sliding of the support base 31 along the first direction; the first drive motor 32 drives the mixer 33 to stir, and simultaneously adds powder and liquid materials through the transmission component 35 in conjunction with the distributor 34, ensuring uniform mixing of materials. This solves the problems of low mixing efficiency and poor material mixing effect of traditional screw conveyors, realizes simultaneous mixing and feeding, improves the uniformity of ceramic slurry, and optimizes the quality of capacitor production.

[0044] For some implementation methods of this statement, please refer to Figure 3 The material distributor 34 includes a support frame 341, a material trough 342, and a top cover 343. The support frame 341 is mounted on a support base 31. The material trough 342 is hollow and open at the top, and is rotatably mounted on the support frame 341. The support frame 341 moves synchronously with the support base 31, and the support frame 341 can sit on the mixing tank 2. The support frame 341 supports the material trough 342, and the material trough 342 can rotate on the support frame 341. Multiple material distribution holes 348 are evenly distributed on the material trough 342, allowing material entering the material distributor 34 to fall through the material distribution holes 348. For example, the material trough 342 is connected to the transmission assembly 35. Under the driving action of the mixer 33, the transmission assembly 35 drives the material trough 342 to rotate, and the material falls from the material hole 348 and is evenly sprinkled into the mixing tank 2 under the action of rotation.

[0045] The mixer 33 passes through the support frame 341 and the material trough 342. When the support frame 341 is placed on top of the mixing tank 2, the mixer 33 can stir the mixed materials in the mixing tank 2.

[0046] The top cover 343 is used to close the opening of the fabric trough 342. The top of the fabric trough 342 is used for feeding. For example, the top cover 343 and the fabric trough 342 are slidably engaged. When the fabric trough 342 rotates, the top cover 343 remains stationary and closes the fabric trough 342 to prevent the material in the fabric trough 342 from escaping.

[0047] In some embodiments of this application, the support frame 341 can close the top opening of the mixing tank 2, preventing the internal material from escaping and causing pollution when the mixing tank 2 is mixing.

[0048] For some implementation methods of this statement, please refer to Figure 4 The material distributor 34 also includes multiple air inlets 344 and an air pump 345. The multiple air inlets 344 are evenly distributed on the top cover 343. Each air inlet 344 is connected to the air pump 345 via a valve head. The air pump 345 injects air into the material distribution trough 342 through the air inlet 344. Powered by the air pump 345, the airflow is diverted by the valve head and injected into the material distribution trough 342 through a pipeline. This pressurization facilitates the flow of material out of the material distribution holes 348. For example, the multiple air inlets 344 are evenly arranged to improve the uniformity of air intake.

[0049] In some embodiments of this application, the distributor 34 further includes a liquid inlet 346 and a liquid inlet pipe 347 connected to the liquid inlet 346. The liquid inlet 346 is fixedly provided on the support frame 341, and the liquid inlet pipe 347 is used to pump liquid from the liquid inlet 346 into the mixing tank 2. The liquid inlet pipe 347 is connected to an external liquid supply pipeline for adding liquid.

[0050] In some embodiments of this application, a feeding tank 311 is provided on the support base 31, and a control material pipe 312 is provided between the feeding tank 311 and the top cover 343 to connect the feeding tank 311 and the material distribution trough 342. Material can be added into the feeding tank 311, so that the material falls from the control material pipe 312 into the material distribution trough 342 to supply material to the material distribution trough 342.

[0051] For some implementation methods of this statement, please refer to Figure 5The transmission assembly 35 includes a drive wheel 351, a gear set 352, and a follower wheel 353. The drive wheel 351 is annularly disposed around the mixer 33, the gear set 352 meshes with the drive wheel 351, and the follower wheel 353 is disposed in the fabric trough 342 and meshes with the gear set 352. During the operation of the mixer 33, the mixer 33 synchronously drives the drive wheel 351 to rotate, and the drive wheel 351 drives the follower wheel 353 to rotate through the gear set 352, so that the follower wheel 353 drives the fabric trough 342 to rotate. For example, the fabric trough 342 has an annular structure, and the inner side of the fabric trough 342 is fixedly connected to the follower wheel 353 so that the fabric trough 342 can rotate together with the mixer 33.

[0052] In some embodiments of this application, the mixer 33 includes a mixing shaft 331 and a mixing element 332 annularly disposed around the mixing shaft 331. The mixing shaft 331 passes through a support frame 341, and a drive wheel 351 is connected to the side of the mixing shaft 331 away from the mixing element 332. Specifically, the mixing shaft 331 is rotatably engaged with the support frame 341, and the mixing shaft 331 is connected to a first drive motor 32, so that the first drive motor 32 drives the mixing shaft 331 to rotate the mixing element 332 along a second direction. The second direction is set at an angle to the first direction, and the second direction can be a horizontal direction, so that the mixing element 332 can stir and mix the materials. For example, the second direction is a horizontal direction and can be perpendicular to the first direction.

[0053] In some embodiments of this application, the processing equipment further includes a second drive motor 14, which is mounted on the bracket 1 and is used to drive the support base 31 to slide along the first direction.

[0054] In some embodiments of this application, the processing equipment further includes a second drive motor, which is mounted on a support and is used to drive the support base to slide along a first direction.

[0055] Secondly, for example, the application of the above-mentioned equipment for ceramic slurry mixing includes the following steps:

[0056] Step S100 Equipment Initialization and Inspection

[0057] Step S110: Check whether the support base, guide rail and card holder are stable, and confirm that the mixing tank limit device is not loose; check whether the sliding mechanism of the support seat is smooth, and ensure that there is no jamming in the first direction (vertical direction).

[0058] Step S120: Verify the meshing state of the transmission gear sets of the first drive motor, the second drive motor, and the transmission assembly, and confirm the synchronous rotation of the drive wheel and the follower wheel; check the sealing performance of the fabric spreader support frame and the top of the mixing tank to ensure that the top cover slides properly.

[0059] Step S130: Test the connection between the air pump and the air inlet to verify the stability of the airflow controlled by the valve head; check the sealing of the liquid inlet pipe and the external liquid supply pipe to confirm that there is no leakage during liquid filling.

[0060] Step S200: Installation and positioning of the mixing tank

[0061] Step S210: Place the mixing bucket in the bracket base holder and fix the bucket body by the holder limiting structure to ensure that the mixing bucket axis is parallel to the first direction and the attitude is stable.

[0062] Step S220: Adjust the support base to slide along the guide rail to the initial high position so that the mixer is completely separated from the mixing tank; calibrate the alignment marks of the support frame and the top of the mixing tank to ensure that the support frame is accurately positioned at the top opening of the mixing tank after the support base is lowered.

[0063] Step S300 Material pre-filling and distribution device configuration

[0064] Step S310: Pre-add some ceramic powder into the feeding trough through the feeding bucket, adjust and control the powder flow rate by adjusting the control pipe valve; connect the liquid inlet pipe to the external liquid supply system, and pre-add liquid to the liquid inlet for later use.

[0065] Step S320: Start the air pump and inject compressed air into the material distribution trough through the air inlet. Adjust the valve opening to maintain the pressure in the material distribution trough at 0.2-0.5MPa to ensure that the powder is evenly distributed through the material distribution holes.

[0066] Step S330: Close the sliding seal between the top cover and the fabric trough, check the flexibility of the fabric trough rotation mechanism, and confirm that the follower wheel and gear set are engaged without deviation.

[0067] Step S400 Mixing-Fabric Linkage Operation

[0068] Step S410: Start the second drive motor to drive the support base to descend along the first direction, so that the mixer is inserted into the mixing tank to the preset depth; simultaneously start the first drive motor to drive the mixing shaft to rotate, and stir the material in the horizontal direction (second direction) through the mixing component.

[0069] In step S420, the transmission assembly transmits power through the drive wheel, gear set, and follower wheel to drive the material distribution trough to rotate. When the material distribution trough rotates, the powder is sprinkled from the evenly distributed material distribution holes, and the liquid is continuously added through the liquid inlet pipe, so as to achieve mixing and feeding at the same time.

[0070] Step S430: Monitor the matching degree between the mixer speed (50-200 rpm recommended) and the material distribution trough speed (25-100 rpm recommended), and optimize the material mixing uniformity by adjusting the power of the first drive motor; observe the state of the slurry in the mixing tank, and adjust the air pump pressure or liquid inlet flow rate as appropriate.
