Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic capacitor preparation, in particular to a ceramic piece supporting and firing fixture. Background Art

[0002] Multilayer ceramic capacitors are constructed by stacking multiple dielectric films with printed inner electrodes in an offset arrangement. The electrodes are then sealed at both ends, creating an inorganic dielectric capacitor. These capacitors feature non-polarity, high reliability, high precision, high integration, high frequency, intelligent operation, low power consumption, large capacity, miniaturization, and low cost, making them widely used in various electronics fields. During the assembly and soldering process for the ceramic capacitor's support sheet, solder paste and flux are applied to both ends. After the support sheet is attached, it is placed on the ceramic sheet and then soldered in a reflow oven. Under high temperatures, the solder paste and flux flow onto the ceramic sheet and solidify. Conventional cleaning methods, such as organic solvents and water, are inadequate for cleaning and are expensive. Currently, high-temperature furnaces are used to burn and evaporate pollutants. However, because the ceramic sheets are stacked in the furnace, most do not receive sufficient heat, resulting in poor cleaning results. Residual flux can also contaminate the product, and small batches of ceramic sheets do not efficiently utilize the furnace space. Therefore, a suitable ceramic sheet support fixture is needed.

[0003] Patent document CN114300282A discloses a welding fixture for manufacturing ceramic capacitors, including a lower mounting plate, an intermediate side plate, and an upper mounting plate. A limiting strip is fixedly installed on the side wall of the intermediate side plate, and a first fixing mechanism for auxiliary fixing of the capacitor is installed on the upper surface of the lower mounting plate. This invention applies pressure to the elastic plate through the end of the capacitor and fits tightly with the elastic plate, ensuring the fixation of the capacitor from the bottom end and improving the stability of the capacitor during welding. Rectangular grooves are provided between the limiting circular holes, making placement more convenient. A rectangular strip is provided on the upper surface of the partition to fix the placement of the ceramic capacitor. However, the number of fixtures fixed by this fixture is limited by the number of rectangular strips, and the way this fixture is inserted into the ceramic capacitor is different from that of this application.

[0004] The patent document with announcement number CN213352200U discloses a chip loading fixture for the production of ceramic capacitors, including a base plate, a movable plate, an adjustment assembly and a back plate. The movable plate is slidably connected to one side of the top of the base plate, the adjustment assembly is fixedly connected to the middle of the side of the base plate, and one end of the adjustment assembly is rotatably connected to the movable plate. The back plate is movably connected to the other side of the top of the base plate. The adjustment assembly includes a vertical plate, a threaded sleeve, a screw, a handwheel and a bearing. The vertical plate is fixedly connected to the middle of the side of the base plate, and the threaded sleeve is embedded in the top of the middle of the vertical plate. The utility model rotates the handwheel to make the screw rotate inside the threaded sleeve. Through the limitation of the threaded sleeve, the movable plate moves back and forth, and the distance between the movable plate and the back plate is adjusted, ensuring the stability of the ceramic capacitor fixation. However, the fixture does not have a structure for fixing the top area of ​​the clamped object, and is not suitable for clamping ceramic pieces with larger lengths or heights. Utility Model Content

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0022] Example:

[0023] like Figures 1 to 3 As shown, a ceramic wafer support fixture includes a base plate 1, a support plate 5, a cover plate 8, and a limit plate 12. The base plate 1 is connected to the lower portion of the support plate 5 on both sides, and the cover plate 8 is connected to the upper portion of the support plate 5 on both sides. One side of the base plate 1 is connected to the limit plate 12. The base plate 1 is provided with a groove a2 and a cavity a3, and the groove a2 is provided on both sides of the cavity a3. The base plate 1, the two support plates 5, and the cover plate 8 are made of a material that is not easily deformed at high temperatures, preferably alloy steel.

[0024] The groove a2 is disposed within the groove c13, and a plurality of grooves a2 are disposed parallel to each other within the groove c13. The grooves a2 correspond vertically to the grooves b9, one-to-one, to vertically clamp the ceramic sheet. The grooves a2 and the corresponding grooves b9 can hold multiple ceramic sheets, and the width of the grooves a2 and b9 is slightly greater than the thickness of the ceramic sheet, making it easier to insert the ceramic sheet.

[0025] The bottom plate 1 is provided with a groove d14, and a through hole a4 is provided in the groove d14, which facilitates the use of the threaded pair. The bottom plate 1 is fixed to the support plate 5 by the threaded pair through the through hole a4 and the through hole b6.

[0026] The support plate 5 is provided with a through hole b6 and an oblong hole 7, with the through hole b6 located at the bottom of the support plate 5 and the oblong hole 7 located at the top of the support plate 5. The support plate 5 is fixedly connected to the cover plate 8 via a threaded pair through the oblong hole 7 and the through hole c10. The spacing between the cover plate 8 and the base plate 1 can be adjusted by adjusting the position of the oblong hole 7 and the through hole c10 to accommodate ceramic pieces of different lengths.

[0027] The cover plate 8 is provided with a groove b9 and a cavity b11 , and the groove b9 is provided on both sides of the cavity b11 .

[0028] The groove b9 is arranged in the groove e15, and a plurality of grooves b9 are arranged in parallel in the groove e15.

[0029] A groove f16 is provided in the cover plate 8 , and a through hole c10 is provided in the groove f16 . The provision of the groove f16 facilitates the use of the threaded pair.

[0030] The height of the bottom plate 1 is less than that of the limiting plate 12 , and the length of the bottom plate 1 is less than or equal to the length of the limiting plate 12 . The limiting plate 12 is vertically arranged to the groove a2 to limit the ceramic piece placed therein.

[0031] When in use, adjust the oblong hole 7 to adjust the distance between the bottom plate 1 and the cover plate 8. After it is slightly larger than the height of the ceramic piece to be clamped, insert a ceramic piece between each groove a2 and groove b9 from the side away from the limiting plate 10. The limiting plate 10 blocks the ceramic piece to prevent it from falling. After each groove a2 and groove b9 are filled with ceramic pieces, put them into the high-temperature furnace, leaving cavity a3 and cavity b11 without isolating heat. At the same time, due to the restrictions of groove a2 and groove b9, there is a gap in each ceramic piece, which allows each ceramic piece to be effectively heated, improving the cleaning effect, and effectively utilizing the space of the high-temperature furnace.
