Description

Technical Field

[0001] This utility model relates to the field of multilayer ceramic chip capacitor (MLCC) technology, and in particular to a rotary firing device. Background Technology

[0002] Currently, pusher-plate furnaces are used for sintering the ceramic bodies of multilayer ceramic capacitors (MLCCs). During operation, the ceramic bodies are laid in a single layer on a firing plate (a four-corner zirconia plate). These firing plates are then stacked layer by layer, forming a "building," arranged in a 2x2 pattern on a zirconia base. The zirconia base is then pushed into the furnace chamber by pusher plates for sintering. However, the sintering furnace heats the ceramic bodies through silicon molybdenum rods located on the upper and lower sides of the furnace chamber, transferring heat via radiation. This results in the upper and lower layers of a "building" receiving optimal heating, while the remaining layers are heated unevenly, leading to significant differences in the color, electrical properties, and mechanical properties of the sintered ceramic bodies. Utility Model Content

[0003] The purpose of this utility model is to provide a rotary firing device that allows the firing plate to rotate within the space of the sintering furnace, so that the ceramic body is heated evenly and avoids the problem of inconsistent sintering effect of the ceramic body caused by the setting position of the heating device in the sintering furnace.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, they should not be construed as limitations on this utility model. It should also be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0025] Please see Figures 1 to 5A preferred embodiment of this utility model provides a rotary firing device, which includes two supports 1, two turntables 2, multiple firing plates 3, and multiple connecting rods 4. The two supports 1 are arranged at intervals, and the upper end of each support 1 is rotatably connected to one of the turntables 2. The multiple connecting rods 4 are arranged between the two turntables 2 on both sides and are evenly spaced along the circumference of the turntables 2. The two ends of the connecting rods 4 are fixedly connected to the two turntables 2 on both sides respectively. The number of firing plates 3 corresponds one-to-one with the number of connecting rods 4. The firing plate 3 is fixedly provided with a swing rod 5, which is rotatably connected to the connecting rods 4. The firing plate 3 is provided with a placement groove 31 for placing porcelain. The firing plate 3 always remains horizontal when rotating.

[0026] According to the rotary firing device of this embodiment, the firing plate 3 can rotate under the drive of the turntable 2, so that the firing plate 3 rotates within the furnace space of the sintering furnace 8. Compared with the previous fixed arrangement of stacked firing plates, the ceramic body can be heated more evenly, avoiding the problem of inconsistent sintering effect of ceramic body caused by the setting position of the heating device in the sintering furnace 8.

[0027] For example, such as Figure 1 and Figure 4 As shown, in order to facilitate the movement of the device into or out of the sintering furnace 8, the rotary sintering device in this embodiment also includes a pusher plate 6. The lower ends of the supports 1 on both sides are fixedly connected to the pusher plate 6, and the pusher plate 6 is slidably disposed in the sintering furnace 8 via a slide rail 7.

[0028] For example, such as Figures 3 to 5 As shown, to increase the automation level of the turntable 2 during rotation and thus improve sintering efficiency, a drive mechanism 9 for driving the turntable 2 to rotate is provided on the outer side of the sintering furnace 8. In this embodiment, the drive mechanism 9 specifically comprises a motor 91, a driving wheel 92, a driven wheel 93, a belt 94, and a transmission shaft 95; a rotating shaft 10 is provided on the turntable 2, the rotating shaft 10 is rotatably connected to the support 1 through a first bearing 11, and the rotating shaft 10 passes through the support 1; the driving wheel 92 is coaxially connected to the output shaft 911 of the motor 91, the driving wheel 92 is drively connected to the driven wheel 93 through the belt 94, the driven wheel 93 is coaxially connected to the transmission shaft 95, and the transmission shaft 95 extends through the side wall of the sintering furnace 8 into the interior of the sintering furnace 8 and is connected to the rotating shaft 10.

[0029] The end of the rotating shaft 10 is provided with a connecting part 101, and the connecting part 101 is provided with a first connecting hole 102 for the drive shaft 95 to be inserted into. The wall of the first connecting hole 102 is provided with a first keyway 103. The side wall of the sintering furnace 8 is provided with a guide groove 81 for the connecting part 101 to slide. The end of the guide groove 81 near the door 83 of the sintering furnace 8 is provided with an inlet, and the end of the guide groove 81 away from the door 83 of the sintering furnace 8 is provided with a limiting part 82. The side wall of the sintering furnace 8 is provided with a through hole 84 near the limiting part 82. The driven wheel 93 is rotatably connected to the through hole 84 through a second bearing 12. The driven wheel 93 is provided with a second connecting hole 931 for the drive shaft 95 to be inserted into. The wall of the second connecting hole 931 is provided with a second keyway 932. The drive shaft 95 is fixedly connected with a key that matches the first keyway 103 and the second keyway 932. It should be noted that during use, the push plate 6 is slidably mounted in the sintering furnace 8 via the slide rail 7. At the same time, the connecting part 101 is slidably connected in the guide groove 81. When the connecting part 101 abuts against the limiting part 82, the first connecting hole 102 is aligned with the second connecting hole 931, the first keyway 103 is aligned with the second keyway 932, the drive shaft 95 passes through the second connecting hole 931 and is inserted into the first connecting hole 102, and the key passes through the second keyway 932 and is inserted into the first keyway 103. This enables the connection between the driven wheel 93 and the turntable 2 and allows for quick assembly and disassembly. Furthermore, the drive shaft 95 is equipped with a handle 951, which allows the operator to easily hold the drive shaft 95 when quickly connecting the driven wheel 93 and the turntable 2. At the same time, the engagement of the key and the keyway generates torque, ensuring that the torque output by the motor 91 can drive the turntable 2 to rotate.

[0030] For example, such as Figure 4 As shown, the door 83 of the sintering furnace 8 is fixedly connected to the push plate 6. When the connecting part 101 abuts against the limiting part 82, the door 83 can close the entrance of the sintering furnace 8, thereby achieving the effect of closing the door and improving work efficiency.

[0031] For example, such as Figure 2 As shown, the lower end of the swing rod 5 is fixedly connected to the side of the firing plate 3, and the center of gravity of the swing rod 5 is located above the vertical line of the center of the firing plate 3. This design makes the firing plate 3 more stable when rotating and prevents it from tipping over.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
