Abstract
Description
Technical Field
[0001] This application relates to the technical field of MLCC sorting and collection, and in particular to an MLCC collecting device. Background Technology
[0002] Multi-layer ceramic capacitors (MLCCs) are widely used in electronic communication equipment, home appliances, and new energy vehicles.
[0003] During the production of multilayer ceramic chip capacitors (MLCCs), a chamfering process is required to remove burrs and smooth the edges. After chamfering, the MLCC products are mixed with alumina balls used as the grinding medium, and a vibration separator is used to separate them by utilizing the difference in their motion characteristics under vibration.
[0004] In existing technology, the separated MLCC products slide down from the end of the ramp of the sorting machine track and fall directly into the receiving box for collection. To avoid damage to the ceramic of the fragile MLCC products due to impact, the conventional improvement method is to lay a layer of sponge or other soft cushioning pad at the bottom of the receiving box.
[0005] However, this method has significant drawbacks. Once a layer of products has accumulated in the receiving box, subsequent falling products will directly impact the earlier-falling products instead of the cushioning pad. At this point, the cushioning effect of the pad has failed, and the hard collision between products can easily cause ceramic damage, affecting product yield. If the ramp height is reduced to decrease the product descent speed, it will severely limit the product capacity of a single receiving box, leading to frequent box replacements and reduced production efficiency.
[0006] Therefore, there is an urgent need in this field for a receiving device that can effectively prevent collision damage to MLCC products during the collection process while ensuring the receiving capacity. Utility Model Content
[0007] Therefore, it is necessary to provide an MLCC receiving device to address the problems existing in the background technology.
[0008] This utility model provides an MLCC receiving device, which is installed below the discharge end of a vibrating separator for receiving falling MLCC products, including: The buffer box and the receiving box are arranged sequentially from top to bottom; Multi-layered buffer balls, housed within the buffer box, are used to buffer and decelerate the falling MLCC products. The bottom of the buffer box is a mesh plate with mesh openings for MLCC products to pass through. The size of the mesh openings is configured to prevent the buffer balls housed in the buffer box from passing through.
[0009] In one embodiment, a flexible filter cloth is also included, which is tautly covered at the top opening of the receiving box to receive MLCC products falling from the mesh of the screen.
[0010] In one embodiment, the bottom of the buffer box is detachably fixed to the top of the receiving box, and the edge of the flexible filter cloth is pressed tightly, so that the flexible filter cloth is in a taut and supported state in its natural state.
[0011] In one embodiment, the density of the buffer sphere is between 0.02 g / cm³ and 0.06 g / cm³.
[0012] In one embodiment, the diameter of the buffer ball ranges from 5 mm to 35 mm.
[0013] In one embodiment, the number of stacked layers of buffer balls in the buffer box is 3 to 4.
[0014] In one embodiment, the mesh is a nylon mesh, a metal mesh, or an engineering plastic mesh.
[0015] In one embodiment, the volume of the buffer box is less than or equal to the volume of the receiving box.
[0016] In one embodiment, the bottom of the receiving box is also provided with a cushioning pad, the cushioning pad being made of sponge, foam or rubber.
[0017] In one embodiment, the capacity of the receiving box is configured to match the number of MLCC products sorted by the vibratory sorter in a single pass.
[0018] This application discloses an MLCC (Multi-Layer Ceramic Capacitor) receiving device. Through a core structure of "buffer box + buffer balls + mesh plate," the MLCC products undergo effective initial buffering and deceleration during collection. Their falling kinetic energy is significantly absorbed and dispersed by the soft, porous buffer ball layer, resulting in a substantial reduction in the product's speed and impact energy before final stacking. This mechanism fundamentally reduces hard collisions between MLCC products and between products and containers, thereby significantly reducing the probability of ceramic damage. Simultaneously, the buffer ball layer's ability to allow product passage ensures that the buffering effect is continuous and does not fail due to partial product collection, achieving the technical objective of improving product yield while maintaining receiving capacity.

[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0022] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0023] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0024] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0025] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0026] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0027] In existing technology, when sorting and collecting MLCCs after chamfering, the buffer pad at the bottom of the receiving box will quickly fail due to being covered by the products, causing the products to collide with each other and cause ceramic damage. At the same time, in order to ensure the receiving capacity, it is difficult to reduce the product falling height, which increases the impact energy.
[0028] To solve the above problems, this application sets up a buffer box and a receiving box stacked on top of each other, and fills the buffer box with multiple layers of buffer balls, with the bottom sealed by a mesh plate. The solution of this application makes the falling MLCC product 6 first hit the soft and porous buffer ball layer, and the kinetic energy is effectively absorbed and dispersed; then, the product passes through the gaps between the buffer balls and the mesh plate under the action of gravity and continues to fall.
[0029] This process achieves initial buffering and deceleration of the product. Through this core concept, the falling speed and impact energy of the product before final stacking are significantly reduced, thereby fundamentally reducing the probability of ceramic damage, while ensuring that the receiving device can accommodate a sufficient number of products.
[0030] The MLCC receiving device according to embodiments of this application will be described in detail below with reference to the accompanying drawings. Figure 1-3 As shown, in one embodiment, the MLCC receiving device of this application includes a buffer box 1, a receiving box 2, a wire mesh plate 3, and multi-layer buffer balls 4. The dimensions shown in the accompanying drawings of this embodiment are for illustrative purposes only; the actual product dimensions may be much smaller than those shown.
[0031] The buffer box 1 and the receiving box 2 are arranged sequentially from top to bottom. The buffer box 1 is used to provide initial buffering for the MLCC product 6, and the receiving box 2 is used to collect the final MLCC product 6.
[0032] A mesh plate 3 is provided at the bottom of the buffer box 1. The mesh plate 3 is a structural component with uniform mesh openings 31. Its core function is to support the buffer ball 4 on it while allowing the MLCC product 6 to pass through. The specific shape of the mesh openings 31 can be square, rhomboid, or circular. The key dimensional requirements are: the aperture or equivalent diameter of the mesh openings 31 must be larger than the size of the MLCC product 6 to ensure that the MLCC product 6 can pass through smoothly; at the same time, it must be smaller than the diameter of the buffer ball 4 to effectively prevent the buffer ball 4 from falling. In this embodiment, the mesh plate 3 can be made of nylon mesh fabric because it is flexible, wear-resistant, and inexpensive. In other embodiments, the mesh plate 3 can also be a metal mesh or a high-strength engineering plastic mesh.
[0033] Multi-layered buffer balls 4 are housed within the buffer box 1 and placed directly on the mesh plate 3. The buffer balls 4 act as the first-stage energy absorbers. When the MLCC product 6 falls from the end of the sorting machine track, it first impacts these buffer balls 4. Because the buffer balls 4 are soft and elastic, they effectively absorb the impact kinetic energy of the MLCC product 6, significantly reducing its speed, thus achieving buffering and deceleration. The natural gaps between the buffer balls 4 provide a channel for the product to continue falling.
[0034] The working process of the MLCC collecting device in this embodiment is as follows: After the MLCC product 6 falls from the end of the track of the vibrating sorter, it first falls into the buffer ball 4 layer of the buffer box 1. Under the buffering effect of the buffer ball 4, the falling speed of the product is effectively controlled. Subsequently, under the action of gravity, the product passes through the gap between the buffer balls 4, and then through the mesh 31 of the screen plate 3, continuing to fall downwards, and finally enters the collecting box 2 to complete the collection.
[0035] The MLCC receiving device in this embodiment utilizes a core structure of "buffer box + buffer balls + mesh plate." During collection, the MLCC products undergo effective initial buffering and deceleration. Their falling kinetic energy is significantly absorbed and dispersed by the soft, porous buffer ball layer, resulting in a substantial reduction in the speed and impact energy of the MLCC products before final stacking. This mechanism fundamentally reduces hard collisions between products and between products and containers, thereby significantly lowering the probability of ceramic damage. Simultaneously, the buffer ball layer's ability to allow product passage ensures that the buffering effect is continuous and does not fail due to partial product collection, achieving the technical objective of improving product yield while maintaining receiving capacity.
[0036] To further optimize the buffering effect, a preferred embodiment of this application adds a flexible filter cloth 5 between the buffer box 1 and the receiving box 2.
[0037] The flexible filter cloth 5 is made of soft woven or non-woven material. The woven material is preferably nylon, polyester, cotton, or a blend thereof; the non-woven material is preferably PP (polypropylene) non-woven fabric or PET (polyester) non-woven fabric. The flexible filter cloth 5 is tautly positioned between the buffer box 1 and the receiving box 2, covering the bottom of the buffer box 1 and the top opening of the receiving box 2. The function of the flexible filter cloth 5 is to receive the MLCC products 6 falling from the mesh plate 3, forming a second buffer barrier. Its "flexibility" and "tension" are key characteristics. When the product falls onto the taut filter cloth, the filter cloth undergoes a slight deformation, further absorbing the remaining energy.
[0038] To ensure the flexible filter cloth 5 remains stably tensioned, the bottom of the buffer box 1 and the top of the receiving box 2 are detachably connected (e.g., with clips or screws). During installation, the edges of the flexible filter cloth 5 are tightly pressed between the mating surfaces of the buffer box 1 and the receiving box 2. This installation method ensures that, under initial no-load conditions, the flexible filter cloth 5 acts like a taut drumhead, providing stable support for the falling product and minimizing the height of the second fall.
[0039] like Figure 2 As shown, in this embodiment, the MLCC product 6 undergoes initial buffering within the buffer box 1 before falling onto the taut flexible filter cloth 5, achieving secondary buffering. Figure 3 As shown, as the number of MLCC products 6 on the filter cloth gradually increases, the flexible filter cloth 5 will slowly sag under the influence of gravity. This process is dynamic: it ensures that the initial drop height of the products is minimized while providing additional storage space for the collection box 2, ultimately achieving the technical effect of collecting a large number of MLCC products 6 under low-impact conditions throughout the process.
[0040] In this embodiment, the product does not need to be removed after it falls onto the flexible filter cloth 5. In the next sealing process, it can be directly fed through the flexible filter cloth 5.
[0041] In one embodiment, to obtain optimal cushioning performance, the parameters of the cushioning ball 4 have been optimized. First, the cushioning ball 4 is made of a lightweight, soft material with a density within a preferred range, for example, 0.02 g / cm³ to 0.06 g / cm³. Balls within this density range are lightweight, preventing pressure damage to the product, while possessing good elasticity and deformation recovery capabilities, enabling efficient absorption of impact energy.
[0042] Secondly, the diameter of the buffer ball 4 is designed to be between 5mm and 35mm. This size range ensures that a stable and appropriately sized gap can be formed between the balls, facilitating the smooth passage of the MLCC product 6 while also forming a sufficiently thick buffer layer. The specific diameter can be selected according to the size of the MLCC product 6; the smaller the product size, the smaller the diameter of the buffer ball that can be used.
[0043] Based on this, the number of stacked layers of buffer balls 4 inside the buffer box 1 is preferably 3 to 4. This range of layers has been verified in practice to achieve the best balance between ensuring sufficient cushioning effect and smooth product passage. Too few layers will result in insufficient cushioning; too many layers may hinder the product's descent or even reduce the effective cushioning stroke due to excessive stacking.
[0044] In other embodiments, a cushioning pad 7 may also be placed at the bottom of the receiving box 2. The cushioning pad 7 may be made of soft materials such as sponge, foam, or rubber. It forms a last line of defense to absorb the very few products that may fall with high energy and to cushion the vibrations of the products inside the receiving box 2 during movement and placement.
[0045] In addition, the volume of buffer box 1 is less than or equal to the volume of receiving box 2, which ensures that buffer box 1, as a buffer, has a compact structure, while receiving box 2, as the main container, has a large enough capacity to receive all products in a single sorting operation, reducing the frequency of replacement and improving production efficiency.
[0046] In one embodiment, the capacity of the receiving box 2 is specifically configured to match the number of MLCC products 6 sorted by the vibratory sorter in a single operation. This means that, under standard workflow conditions, after one sorting operation is completed, the receiving box 2 is filled to near full capacity, thereby maximizing equipment utilization and operational efficiency.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
