Description

Technical Field

[0001] This utility model relates to the field of ceramic capacitor manufacturing technology, and in particular to an air blowing structure. Background Technology

[0002] In the manufacturing process of surface-mount ceramic capacitors, the firing process is a crucial step to ensure product performance. The firing process involves placing the end-capping ceramic particles into a high-temperature furnace and sintering them at high temperatures to form a metallurgical bond between the copper (or silver) end electrodes and the substrate, thereby ensuring the reliability of the electrode connection and the stability of electrical performance.

[0003] Currently, the industry generally uses manual feeding: operators need to manually lay the microcapacitor particles one batch at a time on the nickel grid and then transfer them to the sintering furnace.

[0004] In the process of laying microcapacitor particles, a blower box is commonly used to assist in dispersion to ensure product dispersion. This involves using a compressed air system to blow air onto the nickel mesh through air pipes. However, this method has the following drawbacks: First, uneven airflow. Traditional blower boxes use a compressed air system to blow air through air pipes. The characteristics of compressed air and air pipes are low volume and high pressure, making it difficult to create a uniform air field. This results in excessive airflow in the center of the blower nozzle and insufficient airflow at the sides. This not only fails to disperse the product but also disrupts the neatly arranged particles. Second, secondary accumulation occurs. The dispersed particles form a ring-shaped accumulation zone at the edge of the nickel mesh due to turbulence. Both of these defects can lead to regional electrode soldering problems due to uneven dispersion.

[0005] Based on the above, in the existing technology, the method of using a blower box below the nickel mesh to help disperse microcapacitor particles has the problem of uneven airflow causing the product to be blown around. Utility Model Content

[0006] This invention provides an air-blowing structure that can solve the problem of uneven airflow causing the product to be blown around in the existing method of using a blower box below the nickel mesh to help disperse microcapacitor particles.

[0007] An air-blowing structure, comprising:

[0008] Variable frequency blower;

[0009] A connecting pipe, wherein the air inlet end of the connecting pipe is located at the air outlet end of the variable frequency blower;

[0010] An air blowing box, wherein the air blowing box is a box structure with an internal cavity, and an air inlet is provided at the rear end of the air blowing box, and the air outlet of the connecting pipe is connected to the internal cavity of the air blowing box through the air inlet;

[0011] The air blowing box has at least one air blowing port on its top.

[0012] Furthermore, the cross-section of the air inlet is rectangular.

[0013] Furthermore, the width of the air inlet is 0.1mm-20mm.

[0014] Furthermore, the upper longitudinal section of the air-blowing box is triangular or trapezoidal.

[0015] Furthermore, the upper longitudinal section of the air-blowing box is in the shape of a right-angled trapezoid.

[0016] Furthermore, the front end of the air blowing box is provided with two oppositely arranged mounting adapters.

[0017] Furthermore, the mounting adapter is provided with a mounting card interface.

[0018] Furthermore, the connecting pipe is a rigid pipe or a flexible corrugated pipe.

[0019] Furthermore, the air inlet end of the connecting pipe is fixed to the air outlet end of the variable frequency blower by means of flange connection or clamp connection.

[0020] Furthermore, the outlet end of the connecting pipe is fixed to the air inlet at the rear end of the air blowing box via a flange connection.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model provides an air-blowing structure, which includes a variable frequency blower, a connecting pipe, and an air-blowing box. At least one air-blowing port is provided on the top of the air-blowing box. It has the following advantages: First, by using a variable frequency blower in conjunction with the connecting pipe to supply air to the air-blowing box, the blower can adjust the airflow. By optimizing the pipe connection and adjusting the airflow, a uniform and stable air field is formed at the air-blowing port of the air-blowing box, solving the problem of products not being able to be dispersed. Second, since the air-blowing box can be placed below the nickel mesh, its air-blowing method can provide a certain buoyancy for the scattered products, ensuring uniform dispersion while reducing the rebound of the products during the fall. Third, by setting an independent connecting pipe as the connection medium between the variable frequency blower and the air-blowing box, the two are physically separated. The air-blowing box can be independently installed above, to the side, or below any workstation to be air-blown, without being limited by the fixed position of the variable frequency blower, making it particularly suitable for scenarios with limited space or requiring simultaneous operation of multiple workstations.

[0030] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0031] like Figures 1 to 5 As shown, the present invention provides an air blowing structure, comprising:

[0032] Variable frequency blower 1;

[0033] Connecting pipe 2, the air inlet of connecting pipe 2 is located at the air outlet of variable frequency blower 1;

[0034] The air blowing box 3 is a box structure with an internal chamber. The rear end of the air blowing box 3 is provided with an air inlet 31. The air outlet of the connecting pipe 2 is connected to the internal chamber of the air blowing box 3 through the air inlet 31.

[0035] The top of the air blowing box 3 is provided with at least one air blowing port 4; the top of the air blowing box 3 is provided with one air blowing port 4;

[0036] This air-blowing structure includes a variable frequency blower 1, a connecting pipe 2, and an air-blowing box 3. At least one air-blowing port 4 is located on the top of the air-blowing box 3. It has the following advantages: First, by using a variable frequency blower 1 in conjunction with the connecting pipe 2 to supply air to the air-blowing box 3, the blower 1 can adjust the airflow. By optimizing the pipe connection and adjusting the airflow, a uniform and stable air field is formed at the air-blowing port 4 of the air-blowing box 3, solving the problem of products not being able to be dispersed. Second, since the air-blowing box 3 can be placed below the nickel mesh, its air-blowing method can provide a certain buoyancy for the scattered products, ensuring uniform dispersion while reducing the rebound of the products during the fall. Third, by setting an independent connecting pipe 2 as the connection medium between the variable frequency blower 1 and the air-blowing box 3, the two are physically separated. The air-blowing box 3 can be independently installed above, to the side, or below any workstation to be air-blown, without being limited by the fixed position of the variable frequency blower 1. This is especially suitable for scenarios with limited space or requiring simultaneous operation of multiple workstations.

[0037] In addition, the air blowing port 4 can be set according to the specifications of the nickel mesh. Specifically, the length of the air blowing port 4 can be adapted to the length of the nickel mesh. During the air blowing process, the nickel mesh is driven to move horizontally above the air blowing port 4, thereby effectively avoiding the problem of dead corners or uneven strength, thus greatly improving the quality, performance and batch consistency of the final product.

[0038] like Figures 1 to 5 As shown, in some embodiments of this utility model, a baffle is provided above the air inlet 4, and the baffle is located on the top of the air box 3;

[0039] Specifically, a sealing layer is provided on the bottom surface of the baffle, and the material of the sealing layer can be rubber; the baffle can be fixed to the top of the air blowing box 3 by bolt connection;

[0040] By incorporating a baffle, the area of ​​the air outlet 4 obstructed by the baffle can be precisely controlled by flexibly adjusting its position above the air outlet 4, thereby achieving continuous adjustment of the effective air outlet length. This allows the air blowing structure to easily adapt to nickel meshes of different widths, sizes, or process requirements, significantly improving its versatility and applicability.

[0041] In addition, a sealing layer is provided, which can be made of rubber. By utilizing the good elasticity and sealing performance of rubber, an effective air seal can be formed between the baffle and the top of the air box 3 or the edge of the air port 4 when the baffle is in different adjustment positions. This minimizes air leakage in non-target areas and allows the airflow to be accurately guided and concentrated through the unblocked air port 4 area, ensuring the accuracy and efficiency of airflow control.

[0042] Finally, this baffle design is simple and reliable in structure, easy to process, install and maintain, the adjustment process is intuitive, and the operation is convenient and quick, which helps to improve production efficiency and reduce the difficulty of operation.

[0043] like Figures 1 to 5 As shown, in some embodiments of this utility model, the cross-section of the air inlet 4 is rectangular; the width of the air inlet 4 is 0.1mm-20mm;

[0044] An air inlet 4 is provided at the top of the air blowing box 3. The cross-section of the air inlet 4 is rectangular, with a width of 0.1mm-20mm. The length of the air inlet 4 is greater than its width. The rectangular cross-section of the air inlet 4 allows it to form a uniform and narrow airflow band. The length of the air inlet 4 can be precisely matched to the width of the nickel mesh, ensuring that the airflow can completely cover the entire working width of the nickel mesh without any omissions. This design of matching the width of the nickel mesh avoids the airflow blowing outside the mesh or onto the support structure, preventing waste or interference. The narrow width of the air inlet 4, combined with the rectangular cross-section, helps to maintain the uniformity of airflow speed and pressure distribution along the length of the air inlet, avoiding edge effects or the phenomenon of strong airflow in the middle and weak airflow at both sides. The uniform and stable airflow also reduces the risk of abnormal vibration or displacement of the nickel mesh or product due to uneven airflow impact.

[0045] In addition, the rectangular cross-section generates a stronger airflow directionality, which can be more vertical or concentrated on the product on the nickel mesh at a specific angle. The narrower width design limits the airflow diffusion range, making it more concentrated, which helps to form a stable and controllable blowing effect in specific areas (such as the product surface).

[0046] Finally, in actual use, by driving the nickel mesh to move above the air inlet 4, the uniform, stable and full-coverage airflow can ensure that the products on the mesh are consistently blown, which significantly reduces product quality fluctuations caused by uneven air blowing, improves product consistency and pass rate, and the concentrated and efficient use of airflow helps to reduce unnecessary gas consumption and achieve the purpose of energy saving and consumption reduction.

[0047] like Figures 1 to 5 As shown, in some embodiments of this utility model, the upper longitudinal section of the air blowing box 3 is triangular or trapezoidal.

[0048] In this utility model, the air blowing box 3 is a rectangular box structure. The section parallel to the front side of the air blowing box 3 is marked as the vertical section, the section parallel to the bottom surface of the air blowing box 3 is marked as the cross section, and the section parallel to the right side of the air blowing box is marked as the longitudinal section.

[0049] The upper longitudinal section of the air-blowing box 3 is triangular or trapezoidal. Since an air-blowing port 4 is provided at the top of the air-blowing box 3, the upper triangular or trapezoidal cross section forms a gradually narrowing flow channel. When the airflow flows from the lower part of the box to the upper part, the cross-sectional area of ​​the flow channel gradually decreases, and the airflow speed will increase steadily. This helps to obtain a more stable airflow before reaching the air-blowing port 4. The narrowing structure helps to guide the airflow to flow more smoothly and evenly along the entire length of the air-blowing port 4, reducing internal eddies and dead corners, providing the air-blowing port 4 with a more uniform pressure distribution, and ultimately improving the uniformity of air blowing.

[0050] like Figures 1 to 5 As shown, in some embodiments of this utility model, the upper longitudinal section of the air blowing box 3 is in the shape of a right trapezoid.

[0051] The upper longitudinal section of the air blowing box 3 is in the shape of a right trapezoid. With this design, the rectangular box at the bottom of the air blowing box 3 provides the main pressure stabilizing chamber, while the upper trapezoidal structure serves as an airflow acceleration and guidance channel. The functional zoning is clear and conducive to the optimization of airflow organization.

[0052] The trapezoidal structure converges at the top and naturally connects to the narrow rectangular air inlet 4. This design satisfies the needs for airflow acceleration and guidance while making compact and efficient use of space.

[0053] Trapezoidal structures greatly improve the manufacturability, ease of installation, and space utilization efficiency of structures.

[0054] like Figures 1 to 5 As shown, in some embodiments of this utility model, two oppositely arranged mounting adapters 32 are fixedly installed at the front end of the air blowing box 3; the mounting adapters 32 are provided with mounting card interfaces 33;

[0055] Two opposing mounting adapters 32 are fixedly installed at the front end of the air blowing box 3, forming a symmetrical force system. The air blowing box is simultaneously fixed from both sides through a snap-fit ​​structure, which facilitates the installation of the air blowing box to the relevant feeding equipment. Specifically, the air blowing box 3 can be installed below the nickel mesh, and the specific position is adjusted according to the actual position of the nickel mesh. The mounting adapters 32 can effectively prevent the air blowing box 3 from shifting or twisting laterally under equipment vibration or airflow reaction, ensuring that the air blowing port 4 and the nickel mesh above always maintain precise alignment.

[0056] like Figures 1 to 5 As shown, in some embodiments of this utility model, the connecting pipe 2 is a rigid pipe or a flexible corrugated pipe.

[0057] If the connecting pipe 2 is a rigid pipe, the stability of airflow transmission can be ensured and energy loss can be reduced. It is suitable for fixed workstations or scenarios that require high-precision airflow control.

[0058] If the connecting pipe 2 is made of flexible corrugated pipe, the pipe can be bent and deformed to adapt to complex spatial layouts or scenarios that require frequent adjustment of the air blowing direction, significantly improving the equipment's compatibility with diverse working conditions.

[0059] like Figures 1 to 5 As shown, in some embodiments of this utility model, the air inlet end of the connecting pipe 2 is fixed to the air outlet end of the variable frequency blower 1 by means of flange connection or clamp connection.

[0060] If the air inlet end of the connecting pipe 2 is fixed to the air outlet end of the variable frequency blower 1 by a flange connection: a flange connection is used in the connection between the connecting pipe 2 and the air outlet end of the variable frequency blower 1. High-strength sealing is achieved by bolt tightening to ensure the stability of airflow transmission. At the same time, the standardized design of the flange interface facilitates quick disassembly and reassembly, shortening equipment maintenance downtime.

[0061] If the air inlet end of the connecting pipe 2 is fixed to the air outlet end of the variable frequency blower 1 by means of a clamp connection: the connecting pipe 2 and the air outlet end of the variable frequency blower 1 are connected by a clamp, and the elastic clamping force of the clamp is used to achieve quick installation and disassembly without tools. This is especially suitable for scenarios that require frequent cleaning or replacement of filter components, and significantly improves the maintainability of the equipment.

[0062] like Figures 1 to 5 As shown, in some embodiments of this utility model, the air outlet of the connecting pipe 2 is fixed to the air inlet 31 at the rear end of the air blowing box 3 by means of a flange connection.

[0063] Flange connection is used in the connection between the connecting pipe 2 and the air inlet 31 of the air blowing box 3. High-strength sealing is achieved by bolt tightening to ensure the stability of airflow transmission. At the same time, the standardized design of the flange interface facilitates quick disassembly and reassembly, shortening equipment maintenance downtime.

[0064] This utility model provides an air-blowing structure, which includes a variable frequency blower 1, a connecting pipe 2, and an air-blowing box 3. At least one air-blowing port 4 is provided on the top of the air-blowing box 3. It has the following advantages: First, the variable frequency blower 1 can adjust the air volume. By optimizing the pipe connection and adjusting the air volume, a uniform and stable air field is formed at the air-blowing port 4 of the air-blowing box 3, solving the problem of products not being able to be blown away. Second, the air-blowing box 3 can provide a certain buoyancy for the scattered products, ensuring that the products are blown away evenly while reducing the rebound of the products during the fall. Third, by setting an independent connecting pipe 2 as the connection medium between the variable frequency blower 1 and the air-blowing box 3, the air-blowing box 3 can be installed independently according to actual production needs, which is suitable for scenarios with limited space or multiple workstations that need to operate simultaneously.

[0065] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
