Description

Technical Field

[0001] The utility model relates to the field of electronic technology, in particular to a nozzle used for MLCC production. Background Art

[0002] In the production process of multilayer ceramic capacitors (MLCC, sometimes referred to as "chip capacitors"), a large amount of cutting debris is generated due to the need to cut the ceramic embryo. If these debris are not cleaned up in time, not only the life of the blade will be affected, but also the cutting quality. The existing chip removal solution is to spray water toward the cutting position through a nozzle to wash away the debris.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Utility Model Content

[0004] The inventors found that for cutting thinner products, such as products below 3 mm, using water flushing can basically achieve the desired effect. However, for cutting thicker products, such as products above 4 mm, due to the deep cutting depth, the water flow cannot completely and smoothly enter the cutting path, resulting in the inability to discharge debris in time, and the mixture of debris and water will adhere to the blade, increasing the resistance of the blade, resulting in a decrease in cutting force, seriously affecting the cutting quality of the product, and sometimes even causing the electrode of the capacitor to bend, resulting in product scrapping, reducing the product yield, and on the other hand, causing the blade to be consumed too quickly, thereby increasing production costs.

[0005] In order to solve at least one of the above problems or other similar problems, an embodiment of the utility model provides a nozzle for MLCC production, which can improve the yield and reduce the production cost.

[0006] According to an embodiment of the utility model, a nozzle for MLCC production is provided, the nozzle comprising:

[0007] A first joint part, comprising a first interface connected to a water pipe and a first body part connected to the first interface, wherein a water flow channel communicating with the first interface is provided in the first body part;

[0013] In addition, optionally, the first interface extends at one end of the first part in the same direction as the extending direction of the second part, and a threaded hole communicating with the water flow channel is provided in the first interface.

[0014] In addition, optionally, the first part is further provided with a fixing part for fixing the nozzle at a predetermined position.

[0035] An embodiment of the utility model provides a nozzle for MLCC production. Figure 1 It is a three-dimensional perspective view of an implementation method of the nozzle of the utility model embodiment. Figure 2 yes Figure 1 A side perspective view of the nozzle is shown, Figure 3 is along Figure 2 The cross-sectional view in the AA direction is shown. Figure 4 is along Figure 3 The cross-sectional view along the BB direction.

[0036] like Figure 1 As shown, the nozzle 1 includes a first joint portion 10, a second joint portion 20 and a nozzle portion 30. Figure 2As shown, the first joint part 10 includes a first interface 110 and a first body part 120 connected to the first interface 110. The first interface 110 is used to connect a water pipe, and a water flow channel 120a communicating with the first interface 110 is provided in the first body part 120. Figure 3 As shown, the second joint part 20 includes a second interface 210 and a second main body part 220 connected to the second interface 210, the second interface 210 is used to connect the air pipe, and the second main body part 220 is provided with an air flow channel 220a connected to the second interface 210, at least a portion of the end side of the second main body part 220 extends along the first direction x, and the nozzle part 30 is connected to the first main body part 120 and has a through hole 30a extending along the first direction x and connected to the water flow channel 120a.

[0037] like Figure 3 As shown, the end of the second body portion 220 is inserted into the first body portion 120 from the side of the first body portion 120 opposite to the nozzle portion 30 and extends into the nozzle portion 30, and there is a gap between the outer wall of the second body portion 220 and the inner wall of the nozzle portion 30 for the water flow w to pass through.

[0038] Combine the following Figure 3 and Figure 4 The working process of the nozzle 1 of the embodiment of the utility model is explained. It should be noted that the working process described below is to make the structure of the nozzle 1 of the embodiment of the utility model clearer and should not be understood as a limitation on the nozzle 1 of the embodiment of the utility model.

[0039] In actual use, Figure 4 As shown, the water pipe can be connected to the first interface 110, so that the water flow w can flow along the water flow channel 120a to the nozzle part 30, and because there is a gap between the outer wall of the second body part 220 and the inner wall of the nozzle part 30, as shown in FIG. Figure 3 As shown, the water flow w can enter the through hole 30a of the nozzle portion 30 through the gap; Figure 3 As shown, the air pipe can be connected to the second interface 210, so that the airflow g can flow into the through hole 30a of the nozzle part 30 along the airflow channel 220a, and the water flow w and the airflow g are mixed in the through hole 30a of the nozzle part 30 and then ejected from the nozzle part 30. When it is necessary to remove debris, the outlet of the nozzle part 30 is aligned with the blade cutting position, and the debris is removed by the mixed fluid of the water flow and the airflow ejected from the nozzle part 30. Therefore, by setting a double flow channel of the water flow w and the airflow g in the nozzle 1, the airflow g is added to the water flow w, and a siphon effect is formed to accelerate the flow of the water flow w, thereby improving the chip removal capacity, and the airflow forms cavities in the water flow to take away excess debris, further improving the chip removal capacity, thereby improving the product yield and reducing the production cost.

[0040] In the embodiment of the present utility model, Figure 2 As shown, the first body portion 120 is "L" shaped, including a first portion 121 connected to the first interface 110 and a second portion 122 connected to the nozzle portion 30. Thus, it is convenient to connect water pipes and gas pipes located at different configuration positions. Figure 1 As shown, the nozzle portion 30 extends along the first direction x toward the upper left shown in the figure. Optionally, the nozzle portion 30 may also extend along the first direction x toward the lower right shown in the figure to adapt to water pipes and air pipes in different configuration positions. The embodiment of the utility model does not limit this.

[0041] In addition, optional, such as Figure 1 and Figure 3 As shown, a fixing portion 121a may also be provided on the first portion 121, and the fixing portion 121a is used to fix the nozzle 1 at a predetermined position, for example, to fix the nozzle 1 at a position where the outlet of the nozzle portion 30 is aligned with the cutting position of the blade. The fixing portion 121a may be, for example, a threaded hole that passes through the first portion 121, but the embodiment of the utility model is not limited to this. In addition, whether to provide the fixing portion may be determined according to actual needs.

[0042] In addition, optional, such as Figure 3 As shown, a threaded hole 210a communicating with the air flow channel 220a is provided in the second interface 210, and the threaded hole 210a is, for example, an M3 threaded hole, thereby facilitating connection of the air pipe.

[0043] The channel between the end of the second main body 220 and the end of the nozzle part 30 is called the "water-gas common channel". The length of the water-gas common channel cannot be too long, otherwise it will easily slow down the water flow speed and affect the debris removal effect. The length of the water-gas common channel cannot be too short either, otherwise it will easily cause the mixed fluid of water flow and air flow to diverge, which will also affect the debris removal effect.

[0044] In the embodiment of the present utility model, Figure 3 As shown, the distance D between the end of the second body 220 and the end of the nozzle 30 (i.e., the length D of the water-gas common channel) is 2 to 4 times the inner diameter d of the end of the second body 220. Thus, it is possible to prevent the water-gas mixed fluid from diverging while ensuring the water flow speed, further improving the chip removal capability. The inner diameter d of the end of the second body 220 is, for example, 2 mm to 2.5 mm, and the length of the water-gas common channel is, for example, 6 mm to 8 mm.

[0045] Figure 5 It is a stereogram of another embodiment of the nozzle of the utility model. Figure 6 yes Figure 5 A front view of the nozzle shown, Figure 7 is along Figure 6The cross-sectional view along the CC direction is shown. Figure 8 is along Figure 6 The cross-sectional view in the FF direction.

[0046] Figure 5 The nozzle structure shown is similar to Figure 1 The structures of the nozzles shown have the same features. The same structures can be referred to in the aforementioned embodiments and will not be described in detail here. The following mainly describes the different structures.

[0047] In at least one embodiment, Figure 1 and Figure 2 As shown, the first interface 110 is a through hole formed in the first portion 121. Optionally, as Figure 5 As shown, the first interface 110 extends at one end of the first portion 121 in the same direction as the extending direction of the second portion 122. Figure 7 As shown, a threaded hole 110a communicating with the water flow channel 120a is provided in the first interface 110. Thus, different first interfaces 110 can be designed to adapt to water pipes of different configurations.

[0048] in addition, Figure 3 As shown, the extension direction of the nozzle portion 30 is not perpendicular to the extension direction of the first portion 121. Figure 6 As shown, the extension direction of the nozzle portion 30 is perpendicular to the extension direction of the first portion 121. The embodiment of the utility model does not limit the angle between the extension direction of the nozzle portion 30 and the extension direction of the first portion 121, and the angle can be any angle as long as the outlet of the nozzle portion 30 can be aligned with the cutting position of the blade after the nozzle 1 is fixed.

[0049] As described above, the nozzle provided by the utility model increases the airflow in the water flow through a simple structure, forming a siphon effect to accelerate the flow of water, thereby improving the chip removal capacity, and the airflow forms holes in the water flow to carry away excess debris, further improving the chip removal capacity, thereby improving the product yield and reducing production costs.

[0050] The present application is described above in conjunction with specific implementation methods, but it should be clear to those skilled in the art that these descriptions are exemplary and are not intended to limit the scope of protection of the present application. Those skilled in the art can make various modifications and variations to the present application based on the spirit and principles of the present application, and these modifications and variations are also within the scope of the present application.
