Description

Technical Field

[0001] This application relates to the field of MLCC processing equipment technology, and in particular to a rapid cooling and transfer device for MLCCs. Background Technology

[0002] Multi-layer ceramic capacitors (MLCCs) are heated to high temperatures by a heating device and then discharged to a cooling device through a vibrating discharge pipe. Because the MLCCs are at a high temperature during discharge, they oxidize upon contact with air during the cooling process. Utility Model Content

[0003] Therefore, it is necessary to provide a rapid cooling transfer device for transferring and instantly cooling MLCCs by means of inert gas protection, which is located between the heating device and the cooling device of MLCC, in order to address the problems existing in the background technology.

[0004] This utility model provides a rapid cooling and transfer device for MLCCs, comprising: A receiving pipe, one end of which forms a receiving port and the other end forms a discharge port; The air blowing pipe extends into the receiving pipe from the discharge port, and the end of the air blowing pipe is closed. A discharge channel for MLCC movement is formed between the outer wall of the air blowing pipe and the inner wall of the receiving pipe. A plurality of air blowing holes are provided on the periphery of the air blowing pipe, and the air blowing holes are connected to an external air source and the discharge channel.

[0005] In one embodiment, the receiving port is formed into a funnel structure.

[0006] In one embodiment, a first notch is provided on one side of the funnel structure.

[0007] In one embodiment, the discharge port is provided with a second notch, and the orientation of the second notch is opposite to the orientation of the first notch.

[0008] In one embodiment, the receiving port is provided with a mounting plate that covers the adjacent area of ​​the first notch; the mounting plate is provided with a fixing hole, and the air blowing pipe passes through the fixing hole and extends into the receiving pipe.

[0009] In one embodiment, the receiving pipe is provided with a purging port near the discharge port, and the purging port is disposed opposite to the second notch.

[0010] In one embodiment, the axis of the air blowing pipe coincides with the axis of the receiving pipe.

[0011] In one embodiment, the cross-section of the receiving pipe and the blowing pipe is circular.

[0012] In one embodiment, the air blowing holes are distributed in at least two groups along the axial direction of the receiving pipe, and each group includes four air blowing holes evenly arranged circumferentially.

[0013] In one embodiment, the end of the air tube extends below the neck of the funnel structure.

[0014] The rapid cooling and transfer device for MLCCs described in the above embodiments is installed between the heating and cooling devices of the MLCC. One end of the receiving pipe forms a receiving port to receive the high-temperature MLCCs output from the heating device, while the other end forms a discharge port to input the MLCCs into the cooling device. An air blowing pipe is installed inside the receiving pipe, introducing low-temperature inert gas from an external air source into the discharge channel between the receiving pipe and the air blowing pipe. This prevents the high-temperature MLCCs in the discharge channel from contacting air and undergoing oxidation-reduction reactions, thus protecting the MLCC structure. Furthermore, the low-temperature inert gas ensures that the temperature of the discharge pipe remains low, allowing the high-temperature MLCCs output from the heating device to cool down rapidly, improving the performance of the processed MLCCs.

[0024] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the use scenario of a rapid cooling and transfer device for MLCCs according to an embodiment of this application. The rapid cooling and transfer device for MLCCs provided in an embodiment of this application includes a receiving pipe 1 and an air blowing pipe 2. One end of the receiving pipe 1 forms a receiving port 11, and the other end forms a discharge port 12.

[0025] exist Figure 1 In this example, the receiving pipe 1 is above a horizontally arranged furnace core tube and an inclined discharge pipe in the heating device. To accommodate the inclined discharge pipe, the receiving pipe 1 in this embodiment is also inclined during use. When the heating device discharges material, the furnace core tube drives the discharge pipe to vibrate downwards and discharge material into the receiving port 11. The discharge port at the bottom of the discharge pipe corresponds to the receiving port 11. Preferably, the diameter of the receiving port 11 is larger than the diameter of the discharge port at the bottom of the discharge pipe, so that the discharge port can extend into the receiving port 11 to ensure that material does not spill to the outside.

[0026] An air blowing pipe 2 extends into the receiving pipe 1 from the discharge port 12, and the end of the air blowing pipe 2 is closed. A discharge channel 3 for the movement of MLCCs is formed between the outer wall of the air blowing pipe 2 and the inner wall of the receiving pipe 1. Multiple air blowing holes 21 are provided around the periphery of the air blowing pipe 2, and the air blowing holes 21 connect an external air source to the discharge channel 3. The discharge pipe of this application can be applied to any MLCC heating device.

[0027] In one embodiment, the input end of the air blowing pipe 2 is used to connect to an external gas source, which is a low-temperature (including room temperature) inert gas. The inert gas includes one or more of helium, neon, argon, krypton, and xenon.

[0028] The rapid cooling and transfer device for MLCCs described in this application embodiment is installed between the heating and cooling devices of the MLCC. One end of the receiving pipe forms a receiving port to receive the high-temperature MLCCs output from the heating device, while the other end forms a discharge port to input the MLCCs into the cooling device. An air blowing pipe is installed inside the receiving pipe, introducing low-temperature inert gas from an external air source into the discharge channel between the receiving pipe and the air blowing pipe. This prevents the high-temperature MLCCs in the discharge channel from contacting air and undergoing oxidation-reduction reactions, thus protecting the MLCC structure. Furthermore, the low-temperature inert gas ensures that the temperature of the discharge pipe remains low, allowing the high-temperature MLCCs output from the heating device to cool down rapidly, improving the performance of the processed MLCCs.

[0029] Combination Figure 2 As shown, Figure 2 A schematic diagram of a rapid cooling and transfer device for MLCCs according to an embodiment of this application is shown, wherein the receiving port 11 forms a funnel structure 111. When the MLCCs are discharged from the discharge port at the bottom of the discharge pipe of the MLCC heating device by vibration, the funnel structure 111 formed at the receiving port 11 allows the discharge port to fully extend into the funnel structure 111. The funnel structure 111 has a larger space to receive the discharged material, preventing the MLCCs from spilling out of the receiving port 11 and reducing processing losses. Moreover, the larger space of the funnel structure 111 makes it easier to adjust the positional relationship between the discharge port of the MLCC heating device and the discharge pipe, preventing the discharge port from hitting the receiving pipe 1 during vibration and improving stability during use.

[0030] In an optional embodiment, such as Figure 2 As shown, a first notch 112 is provided on one side of the funnel structure 111. By providing the first notch 112, the opening range of the receiving port 11 is increased, thereby improving the convenience of connecting the receiving port 11 to the outlet of the MLCC heating device. This makes it less likely for the outlet pipe to hit the receiving port 11 when it vibrates, which has the advantage of being easy to use. Moreover, when the receiving pipe 11 is tilted, the first notch 112 is set upwards, so even if the outlet vibrates to the outside of the notch 112, the material will not spill to the outside.

[0031] In an optional embodiment, such as Figure 2 As shown, the discharge port 12 is provided with a second notch 121, and the orientation of the second notch 121 is opposite to that of the first notch 112. By providing the second notch 121, the opening range of the discharge port 12 is increased, making the output of MLCCs from the discharge channel 3 smoother, preventing MLCCs from clogging the discharge port 12, and improving the stability of use. In particular, when the receiving pipe 11 is tilted, the first notch 112 is set upwards and the second notch 121 is set downwards, which facilitates the direct drop of MLCCs from the second notch 121, increases the opening range of the discharge port 12, and improves the discharge efficiency of the discharge pipe.

[0032] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the receiving port 11 is provided with a mounting plate 4, which covers the adjacent area of ​​the first notch 112. The mounting plate 4 is provided with a fixing hole 41, through which the air blowing pipe 2 passes and extends into the receiving pipe 1. The air blowing pipe 2 is connected to the mounting plate 4, so that the end of the air blowing pipe 2 near the receiving port 11 is installed through the mounting plate 4, ensuring that no fixing structure for the air blowing pipe 2 is required in the discharge channel 3 between the outer wall of the air blowing pipe 2 and the inner wall of the receiving pipe 1, allowing the MLCC to be discharged smoothly in the discharge channel 3.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the axis of the air blowing pipe 2 coincides with the axis of the receiving pipe 1, ensuring that the distance between the outer wall of the air blowing pipe 2 and the inner wall of the receiving pipe 1 is balanced, avoiding MLCC blockage in the discharge channel 3, and improving stability during use.

[0034] MLCCs may leave residue on mounting plate 4 during discharge. To address this issue, in an optional embodiment, such as... Figure 3 As shown, the receiving pipe 1 is provided with a purging port 14 near the discharge port 12, and the purging port 14 is arranged opposite to the second notch 121. By providing the purging port 14, an external air source can be connected to the purging port 14, thereby blowing off the MLCCs remaining on the mounting plate 4 with high-pressure gas, avoiding MLCC residue on the mounting plate 4 and improving the discharge efficiency of MLCCs.

[0035] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the receiving pipe 1 and the air blowing pipe 2 have circular cross-sections. In this embodiment, the receiving pipe 1 and the air blowing pipe 2 are configured as cylindrical structures, which makes it less likely for MLCCs to accumulate and remain inside the receiving pipe 1, and also reduces manufacturing costs. In other embodiments, the cross-sections of the receiving pipe 1 and the air blowing pipe 2 may also be elliptical, and this application is not limited thereto.

[0036] In an optional embodiment, such as Figure 1 and Figure 2 As shown, at least two sets of air blowing holes 21 are distributed along the axial direction of the receiving pipe 1, and each set includes four air blowing holes evenly arranged circumferentially. By setting multiple air blowing holes 21, the distribution of inert gas in the discharge channel 3 is made more uniform, avoiding the oxidation of the high-temperature MLCC caused by air in the discharge channel 3, and also allowing the MLCC to be cooled more timely and fully, thus improving the processing effect.

[0037] In an exemplary embodiment, the air blowing holes 21 are evenly distributed in 34 groups along the axial direction of the receiving pipe 1, with each group including 4 air blowing holes evenly arranged circumferentially.

[0038] Furthermore, the diameter of the air blowing hole 21 is smaller than the diagonal of the smallest end face of the MLCC. By limiting the diameter of the air blowing hole 21, the MLCC is prevented from falling into the air blowing pipe 2 through the air blowing hole 21 and becoming impossible to clean, thus reducing losses during processing.

[0039] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the end of the air blowing pipe 2 extends to the neck of the funnel structure 111, so that the air blowing pipe 2 is extended and set in the entire discharge channel 3. This allows the inert gas to be evenly distributed to the entire discharge channel 3 through the air blowing pipe 2, preventing the presence of air in the discharge channel 3 from causing oxidation of the high-temperature MLCC. It also allows the MLCC to be cooled more promptly and fully, improving the processing effect.

[0040] In an optional embodiment, the air blowing pipe 2 has a connecting thread on the inner wall of the input end, and the external air source and the air blowing pipe 2 can be connected by the thread to ensure the connection is sealed.

[0041] 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.

[0042] The embodiments described above are merely illustrative of 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.
