Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The technical features designed in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that all terms used in this utility model (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains, and should not be construed as limiting this utility model; it should be further understood that the terms used in this utility model should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this utility model.

[0027] Please see Figures 1-6 This utility model provides an MLCC marking and spraying fixture, which includes at least a base plate 10 and a cover plate 20 located on the base plate 10.

[0028] The base plate 10 has several strip-shaped through slots 11, and several limiting slots 12 are spaced apart along the width direction of the strip-shaped through slots 11. The length of the limiting slots 12 is greater than the width of the strip-shaped through slots 11, and the limiting slots 12 do not penetrate the base plate 10, so as to support the MLCC across the strip-shaped through slots 11 and confine it within the limiting slots 12; the cover plate 20 has several guide slots 21, and the guide slots 21 are correspondingly arranged above the strip-shaped through slots 11, so that the working area of ​​the MLCC on the limiting slots 12 is exposed in the guide slots 21.

[0029] In practical implementation, the base plate 10 is the foundation of the fixture. The surface of the base plate 10 has several through-slots 11 extending through it, and these through-slots 11 are spaced parallel to each other along the length or width direction of the base plate 10. For example, in this embodiment, the through-slots 11 are evenly distributed along the length direction of the base plate 10. The through-slots 11 are used to accommodate and support MLCCs. Each through-slot 11 has several limiting grooves 12 spaced apart along its width direction. The limiting grooves 12 are evenly distributed within the through-slots 11. The length of the limiting grooves 12 is greater than the width of the through-slots 11, but they do not penetrate the base plate 10. This arrangement ensures that the MLCCs can be mounted across the through-slots 11 and effectively restrained in a predetermined position by the limiting grooves 12, preventing displacement during marking or spraying.

[0030] A cover plate 20 covers the base plate 10. The surface of the cover plate 20 has several guide grooves 21 penetrating the cover plate 20, each corresponding to a strip-shaped through groove 11 on the base plate 10. In this embodiment, the guide grooves 21 are preferably strip-shaped guide grooves with the same length as the strip-shaped through grooves 11. The design of the guide grooves 21 allows the area of ​​the MLCC to be worked on (such as the part requiring marking or spraying) in the limiting groove 12 to be exposed in the guide grooves 21 when the cover plate 20 is covering the base plate 10, facilitating subsequent marking or spraying. Specifically, the surface of the MLCC has a workable area and a non-workable area. By designing the shape and size of the guide grooves 21 of the cover plate 20, the non-workable area of ​​the MLCC can be covered by the cover plate 20 while the workable area of ​​the MLCC is exposed through the guide grooves 21, which is beneficial for subsequent personalized marking or spraying operations and expands the application range.

[0031] It should be noted that both ends of the MLCC are covered with metal layers for electrode connection. These metal layers should be avoided during marking and spraying to prevent affecting the electrode connection. Therefore, the width of the limiting groove 12 and the width of the strip-shaped through groove 11 should be designed so that when the MLCC is placed across the strip-shaped through groove 11, its metal layer is located within the limiting groove 12, but not within the strip-shaped through groove 11. Specifically, as follows... Figure 4As shown, the black area on the surface of a single MLCC50 is the area to be marked and coated, while the two sides of the surface are non-working areas covered by a metal layer. When the MLCC is placed horizontally across the strip groove 11, the non-working area of ​​the MLCC is located within the limiting groove 12, but not within the range of the strip groove 11. For details, please refer to... Figure 3 The limiting groove 12 includes a working part 12a within the strip-shaped through groove 11 and two bridging parts 12b extending from the strip-shaped through groove 11 to both sides of the width. The width of the working part 12a should be greater than or equal to the width of the area to be worked on, and the width of the bridging part 12b should be greater than the width of the non-working area (i.e., the width of the metal layer covering the surface of a single MLCC50). In other words, from a top view, the metal layer on the surface of a single MLCC50 is located within the projection range of the bridging part 12b, thereby effectively preventing the metal layer from being affected during marking and spraying.

[0032] Therefore, by using a design where the length of the limiting groove 12 is greater than the width of the strip groove 11, but does not penetrate the base plate 10, it is possible to easily place the MLCC across it, and also to reserve space for the metal layers at both ends of the MLCC, preventing paint from sticking to the metal layers during marking and spraying. Simultaneously, this embodiment incorporates a cover plate 20, utilizing a guide groove 21 with the same width as the strip groove 11, so that the guide groove 21 can completely cover the metal layers at both ends of the MLCC located within the limiting groove 12, further preventing paint from sticking to the metal layers during marking and spraying.

[0033] The specific steps for using the MLCC marking and spraying fixture of this embodiment are as follows:

[0034] 1. Prepare MLCCs: Place the MLCCs to be marked or sprayed in the strip groove 11 of the base plate 10 in a predetermined order, and ensure that the MLCCs are properly restricted by the limiting groove 12.

[0035] 2. Install cover plate 20: Cover the base plate 10 with cover plate 20, ensuring that guide groove 21 is accurately aligned with strip through groove 11, while exposing the MLCC's work area in guide groove 21.

[0036] 3. Marking or spraying operations: Using a marking machine or spraying equipment, the area to be marked on the MLCC is marked or sprayed through the guide groove 21. Since the MLCC is effectively restricted by the limiting groove 12, the accuracy and stability of the operation process can be ensured.

[0037] 4. Remove cover plate 20: After completing the work, remove cover plate 20 from base plate 10 and take out the marked or sprayed MLCC.

[0038] 5. Cleaning and Reuse: Clean the surface of the fixture to remove any residual marking or spraying materials for the next use.

[0039] The MLCC marking and spraying fixture provided in this embodiment has a simple structure, is easy to manufacture and assemble, and is convenient and quick to operate, greatly improving work efficiency. In addition, the design of the limiting groove 12 effectively prevents the displacement of MLCCs during the marking or spraying process, ensuring the accuracy and stability of the operation; and the number and size of the strip through groove 11 and the limiting groove 12 can be adjusted according to actual needs to accommodate MLCCs of different specifications and sizes.

[0040] In an alternative embodiment, please refer to Figure 5 , Figure 6 The guide groove 21 has a top opening 21a and a bottom opening 21b. The bottom opening 21b is located on the surface of the cover plate 20 near the base plate 10, and the top opening 21a is located on the surface of the cover plate 20 away from the base plate 10. The horizontal cross-sectional area of ​​the guide groove 21 gradually decreases from the top opening 21a towards the bottom opening 21b. That is, the guide groove 21 gradually narrows in the direction near the base plate 10, forming a funnel-shaped structure. This design helps guide the work tool (such as a nozzle or marking needle) during marking or spraying, allowing the paint to be sprayed more fully into the guide groove 21, increasing the marking or spraying angle and range of the work tool, enabling it to more accurately align with the area to be worked on the MLCC, while avoiding material waste and contamination due to insufficient marking or spraying angle.

[0041] Furthermore, the guide groove 21 also has a sidewall 21c that connects the top opening 21a and the bottom opening 21b respectively, and the sidewall 21c is an inclined plane. That is, compared with the design of the sidewall 21c being an inclined curved surface or multiple inclined surfaces, the design of the sidewall 21c being an inclined plane can make the spray liquid remaining on the guide groove 21 flow to the strip channel 11 more quickly, and is easier to clean and maintain.

[0042] It should be noted that the dimensions (including width, depth, and length) of the guide groove 21 can be adjusted according to the specifications of the MLCC and the operational requirements, and this embodiment does not impose any limitations on it. For example, for smaller MLCCs, a narrower guide groove 21 can be designed to ensure operational accuracy; while for larger MLCCs, the dimensions of the guide groove 21 can be increased accordingly to accommodate its size.

[0043] In some embodiments, the spacing between the top openings 21a of adjacent guide grooves 21 is less than or equal to the width of the bottom opening 21b. By limiting the spacing between the top openings 21a of adjacent guide grooves 21 to a smaller value, the amount of material remaining between the top openings 21a of adjacent guide grooves 21 can be reduced, allowing the material to flow through the guide grooves 21 into the strip channel 11 as much as possible. Preferably, the spacing between the top openings 21a of adjacent guide grooves 21 is less than or equal to 5 mm, for example, less than or equal to 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm, ensuring high-quality work results even in a compact layout and improving the space utilization of the fixture.

[0044] Furthermore, by setting the spacing between the top openings 21a of adjacent guide grooves 21 to be less than or equal to the width of the bottom opening 21b, and setting the width of the top opening 21a to be greater than the width of the bottom opening 21b, the guiding range can be expanded, and the adjacent MLCCs will not interfere with each other when the cover plate 20 covers the base plate 10, thereby reducing operational errors and material waste.

[0045] Preferably, a positioning structure 30 is provided between the base plate 10 and the cover plate 20; the positioning structure 30 is used to position the cover plate 20 on the base plate 10 to restrict the movement of the cover plate 20. Through the design of the positioning structure 30, on the one hand, accurate alignment of the guide groove 21 and the strip groove 11 can be ensured; on the other hand, during operation, accidental displacement between the base plate 10 and the cover plate 20 is avoided, which would affect the operation results, effectively improving the stability and operation accuracy of the fixture. The positioning structure 30 can be any irregular snap-fit ​​structure, threaded bolt structure, etc., that can restrict the displacement of the cover plate 20 and the base plate 10; this embodiment is not limited to this.

[0046] Please see Figure 1 In this embodiment, the positioning structure 30 preferably includes at least one positioning shaft 31 located on the base plate 10 and at least one positioning hole 32 located on the cover plate 20, wherein the positioning hole 32 can be sleeved on the positioning shaft 31; and / or, the positioning structure 30 includes at least one positioning shaft 31 located on the cover plate 20 and at least one positioning hole 32 located on the base plate 10, wherein the positioning hole 32 can be nested on the positioning shaft 31.

[0047] The positioning shaft 31 can be a cylindrical, near-cylindrical, conical, or near-conical structure protruding from the surface of the base plate 10 or cover plate 20. Its height and diameter should be designed to match the thickness of the base plate 10 or cover plate 20 and the size of the positioning hole 32. The shape and size of the positioning hole 32 match the positioning shaft 31 to ensure that the positioning hole 32 can accurately fit onto the positioning shaft 31. The depth of the positioning hole 32 should be sufficient to accommodate the head of the positioning shaft 31 to prevent the cover plate 20 from moving vertically.

[0048] Please see Figure 5 The height of the limiting groove 12 is greater than or equal to the thickness of the MLCC, so that the surface of the MLCC located within the limiting groove 12 is lower than or equal to the surface of the base plate 10 near the cover plate 20. Figure 5 The surface of a single MLCC 50 is lower than the surface of the base plate 10 near the cover plate 20. This arrangement prevents the base plate 10 from squeezing the MLCC when it contacts the cover plate 20, ensuring that the MLCC is not damaged during operation. In this embodiment, it is preferable that the surface of the MLCC within the limiting groove 12 is slightly lower than the surface of the base plate 10 near the cover plate 20.

[0049] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the strip-shaped channel 11 has opposing upper openings 11a and lower openings 11b. The upper opening 11a is located on the surface of the base plate 10 near the cover plate 20, and the lower opening 11b is located on the surface of the base plate 10 away from the cover plate 20. The horizontal cross-sectional area of ​​the strip-shaped channel 11 below the limiting groove 12 gradually increases from the upper opening 11a towards the lower opening 11b. That is, the strip-shaped channel 11 is relatively narrow near the limiting groove 12, and gradually widens near the lower side of the base plate 10. The strip-shaped channel 11 forms a trapezoidal slope structure below the limiting groove 12, specifically as shown below the limiting groove 12. Figure 3 , Figure 4 As shown.

[0050] By setting the strip groove 11 relatively narrow near the height of the limiting groove 12, the marking and spraying range can be effectively limited, preventing the marking and spraying area from being too wide and spraying onto the non-working areas covered by the metal layer at both ends of the MLCC. At the same time, the strip groove 11 gradually widens in the direction near the lower side of the base plate 10, allowing excess spray paint to flow out along the slope during the drying process.

[0051] In other alternative embodiments, please refer to Figure 2The cover plate 20 has a plurality of grooves 40 for assisting in the movement of the cover plate 20, and / or the base plate 10 has a plurality of grooves 40 for assisting in the movement of the base plate 10. The grooves 40 can be elongated, arc-shaped, or other shapes, and should be evenly distributed along the edges of the cover plate 20 or the base plate 10. The grooves 40 on the base plate 10 can be used to connect with other accessories to provide support.

[0052] This utility model also provides an MLCC marking and spraying device, which adopts the MLCC marking and spraying fixture as described in any of the above embodiments, and can effectively improve the marking and spraying efficiency and realize mass production.

[0053] In summary, the MLCC marking and spraying fixture and device provided by this utility model, through the structural design of the base plate and cover plate, has the advantages of simple structure, easy manufacturing, assembly and cleaning maintenance, convenient and quick operation, and can be effectively applied to the mass production of MLCCs, greatly improving the efficiency of marking and spraying operations.
