Description

Technical Field

[0001] The present invention relates to the field of common-mode inductor production, and in particular to a common-mode inductor packaging device. Background Art

[0002] Common-mode inductors, also called common-mode chokes, are commonly used in computer switching power supplies to filter common-mode electromagnetic interference signals. In board design, common-mode inductors also serve as EMI filters, suppressing the outward emission of electromagnetic waves generated by high-speed signal lines. Common-mode inductors are essentially two-way filters: on the one hand, they filter out common-mode electromagnetic interference on signal lines, while on the other hand, they suppress outward electromagnetic interference themselves, thereby preventing it from affecting the normal operation of other electronic devices in the same electromagnetic environment. In actual circuit design, multi-stage common-mode circuits can also be used to further filter out electromagnetic interference. Furthermore, surface-mount common-mode inductors can also be found on motherboards, and their structure and function are almost identical to upright common-mode inductors.

[0003] When producing common-mode inductors, they are typically encapsulated and coated with a layer of colloid to enhance their anti-interference capabilities. However, existing packaging jigs are prone to burrs and uneven surfaces, resulting in uneven and rough surfaces on the encapsulated common-mode inductors. Furthermore, existing packaging jigs make it difficult to remove the encapsulated common-mode inductors, reducing production efficiency. Summary of the Invention

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See also Figure 1 and Figure 2 A common-mode inductor packaging device includes: a plurality of packaging jigs 10 distributed in a matrix pattern, wherein in one of the packaging jigs 10, the packaging jig 10 includes a glue injection container 100, a connecting component 200, and a pressing component 300, wherein the glue injection container 100 is provided with a glue injection groove 110, and the connecting component 200 and the pressing component 300 are respectively arranged at the notch position of the glue injection groove 110. It should be noted that the glue injection container 100 is used to inject glue into the common-mode inductor, that is, the common-mode inductor is placed in the glue injection groove and then the glue injection operation is performed, and the glue injection groove can conveniently hold glue; the connecting component 200 is used to connect two packaging jigs and can also play a fixing role; the pressing component 300 is used to press the jig, which facilitates the degumming operation when degumming.

[0031] See also Figure 2 The connection assembly 200 includes a first connection piece 210, a second connection piece 220, and a third connection piece 230. The first, second, and third connection pieces are respectively disposed on the glue injection container and are respectively disposed on the three side edges of the notch of the glue injection tank. The first, second, and third connection pieces 210, 220, and 230 are respectively used to connect packaging jigs at different locations.

[0032] See also Figure 2 and Figure 3 The pressing assembly 300 includes a pressing sheet 310, a first anti-slip strip 320, and a second anti-slip strip 330. The pressing sheet is mounted on the glue injection container and has a first mounting area and a second mounting area. The first anti-slip strip is mounted on the first mounting area, and the second anti-slip strip is mounted on the second mounting area. It should be noted that the pressing sheet 310 facilitates the separation of the jig from the common-mode inductor after glue injection; the first and second anti-slip strips 320 and 330 provide anti-slip protection.

[0033] Furthermore, the glue potting groove is a square fixing groove, and the first connecting piece, the second connecting piece, and the third connecting piece are respectively arranged on the three side edges of the notch of the square fixing groove. It should also be noted that the inner sidewall of the square fixing groove is a smooth surface. In this way, the smooth glue potting groove can avoid the formation of burrs, making the surface of the common-mode inductor smooth and flat after glue potting. The provision of the pressing piece, the first anti-slip strip, and the second anti-slip strip can also facilitate the removal of the common-mode inductor after glue potting, thereby improving the production efficiency of the common-mode inductor.

[0034] Specifically, the pressing piece is located on the fourth side edge of the notch of the square fixing slot. By providing the pressing piece, when separating the common-mode inductor from the packaging jig, the entire packaging jig after the glue filling is turned over, that is, the notch of the glue filling slot is placed downward. The operator then holds the pressing piece with one hand and supports the packaging jig with the other hand. The operator then pulls the pressing piece upward with a certain amount of shaking, and the common-mode inductor and packaging jig are separated.

[0035] It should be noted that the first anti-slip strip is arranged at the middle position of the pressing piece, so that a more stable pulling force can be applied to the pressing piece, thereby improving the reliability during separation.

[0036] It should be noted that the first anti-slip strips are provided in plurality, with spaces provided between each of the first anti-slip strips. In this embodiment, three first anti-slip strips are provided, each of which is provided on the pressing plate. Thus, by providing multiple first anti-slip strips, stability can be improved.

[0037] It should be noted that the second anti-slip strip is provided in the middle of the pressing piece and on the side of the pressing piece away from the first anti-slip strip. In this way, a more stable pulling force can be applied to the pressing piece, improving the reliability during separation.

[0038] It should be noted that there are multiple second anti-slip strips, each of which is spaced apart. In this embodiment, there are three second anti-slip strips, each of which is disposed on the pressing plate. Thus, by providing multiple second anti-slip strips, stability can be improved.

[0039] See also Figure 3 The packaging jig 10 also includes a pull-and-hold member 400, which is disposed on the glue injection container 100 and on a side of the container away from the bottom of the glue injection tank. It should be noted that the pull-and-hold member is used to facilitate pulling the jig and separating the common-mode inductor from the jig.

[0040] See also Figure 3 and Figure 4 The pulling positioning member 400 includes at least one positioning piece 410, which is provided on the injection container 100. It should be noted that when the positioning piece is pulled, the jig can be pulled up, separating the common-mode inductor and the jig. In this embodiment, two positioning pieces can also be provided, and the two positioning pieces are respectively arranged vertically. In this way, by providing two vertical positioning pieces, it is convenient for the operator to pull the jig.

[0041] It can be understood that since the common-mode inductor packaging device is made of plastic material, the entire injection-molded common-mode inductor needs to be taken out of the packaging device during the demolding process of the common-mode inductor. The existing demolding method is to directly take out the entire common-mode inductor manually. Since it is necessary to wait until the glue injected on the entire common-mode inductor cools down before taking it out, and the demolding process is not easy to separate the common-mode inductor and the packaging device, therefore, in order to facilitate the demolding of the common-mode inductor, improve the demolding efficiency of the common-mode inductor, and thus improve the production efficiency of the common-mode inductor; for example, in one embodiment, the The packaging device further includes a heating and demolding component, which includes a heating fixture, a connecting pipe and a heating flow pipe. The heating fixture is arranged on the outer wall of the packaging fixture, and the connecting pipe and the heating flow pipe are respectively arranged on the heating fixture; the heating fixture includes a first fixing plate, a second fixing plate and a bottom plate, the bottom plate is attached to the outer wall of the packaging fixture, the first fixing plate and the second fixing plate are respectively arranged on the bottom plate, and a heat pipe installation area is provided between the first fixing plate and the second fixing plate; the connecting pipe includes a first fixing plate, a second fixing plate and a bottom plate, the bottom plate is attached to the outer wall of the packaging fixture, the first fixing plate and the second fixing plate are respectively arranged on the bottom plate, and a heat pipe installation area is provided between the first fixing plate and the second fixing plate; the connecting pipe includes a heat pipe ... The invention comprises an inlet pipe body, an outflow pipe body, an inlet fixing block and an outflow fixing block, wherein the inlet fixing block is arranged on the bottom plate, and a first fixing groove is provided on the inlet fixing block, and the inlet pipe body is embedded in the first fixing groove, the outflow fixing block is arranged on the bottom plate, and a second fixing groove is provided on the outflow fixing block, and the outflow pipe body is embedded in the second fixing groove, an inlet flow hole is provided on the first fixing plate, one end of the inlet pipe body is communicated with the inlet flow hole on the first fixing plate, and the other end of the inlet pipe body is communicated with the inlet end of the heating flow pipe member , a reflux flow hole is provided on the second fixed plate, one end of the outflow pipe body is connected to the reflux flow hole on the second fixed plate, and the other end of the outflow pipe body is connected to the reflux end of the heating flow pipe fitting; the heating flow pipe fitting includes a disc-type heating pipe body and a plurality of third fixed blocks, each of the third fixed blocks is respectively arranged on the bottom plate, and a third fixed groove is provided on the third fixed block, and the disc-type heating pipe body is respectively embedded in the third fixed groove, the inlet end of the disc heating pipe body is connected to the access pipe body, and the reflux end of the disc heating pipe body is connected to the outflow pipe body. In this way, by setting up heating fixtures, connecting pipes and heating flow pipes, the principle of thermal expansion and contraction can be utilized. When demolding, hot water can be poured into the heating flow pipes, so that the hot water heats the surface of the packaging jig. Because the packaging jig is made of plastic material, after the outer surface is heated, it will expand to a certain extent, thereby expanding the size of the glue filling groove, and finally making it convenient to demold the common-mode inductor after glue injection, thereby facilitating the demolding of the common-mode inductor, improving the demolding efficiency of the common-mode inductor, and thus improving the production efficiency of the common-mode inductor.

[0042] In order to further understand the design concept of the heating and demoulding components and deepen our understanding of the heating and demoulding components, the following is a detailed description of the heating and demoulding components. Figure 5 and Figure 6 The packaging device further includes a heating and demolding assembly 500, which includes a heating fixture 510, a connecting pipe 520, and a heating flow pipe 530. The heating fixture is disposed on the outer wall of the packaging jig, and the connecting pipe and the heating flow pipe are respectively disposed on the heating fixture. In this way, by disposing the heating fixture, the connecting pipe, and the heating flow pipe, the principle of thermal expansion and contraction can be utilized. During demolding, hot water can be poured into the heating flow pipe, causing the hot water to heat the surface of the packaging jig. Since the packaging jig is made of plastic material, after the outer surface is heated, it will expand to a certain extent, thereby expanding the size of the glue injection groove. Ultimately, the common-mode inductor after glue injection can be easily demolded, thereby facilitating the demolding of the common-mode inductor, improving the demolding efficiency of the common-mode inductor, and further improving the production efficiency of the common-mode inductor.

[0043] For details, please refer again to Figure 6 The heating fixture 510 includes a first fixing plate 511, a second fixing plate 512 and a bottom plate 513. The bottom plate is attached to the outer wall of the packaging jig. The first fixing plate and the second fixing plate are respectively arranged on the bottom plate. A heat pipe installation area is provided between the first fixing plate and the second fixing plate. It should be noted that the bottom plate 513 is used to install the heating demolding assembly on the packaging jig. The first fixing plate 511 and the second fixing plate 512 are respectively used to connect the connecting pipes to facilitate the addition of hot water into the connecting pipes. By providing the first fixing plate 511, the second fixing plate 512 and the bottom plate 513, a fixing effect can be achieved, thereby improving the structural stability of the entire assembly.

[0044] See also Figure 6The connecting pipe fitting 520 is arranged in the heat pipe installation area, and the connecting pipe fitting 520 includes an inlet pipe body 521, an outflow pipe body 522, an inlet fixing block 523 and an outflow fixing block 524. The inlet fixing block is arranged on the base plate, and a first fixing groove is provided on the inlet fixing block. The inlet pipe body is embedded in the first fixing groove. The outflow fixing block is arranged on the base plate, and a second fixing groove is provided on the outflow fixing block. The outflow pipe body is embedded in the second fixing groove. An inlet flow hole is provided on the first fixing plate. One end of the inlet pipe body is connected to the inlet flow hole on the first fixing plate, and the other end of the inlet pipe body is connected to the inlet end of the heating flow pipe fitting. A return flow hole is provided on the second fixing plate. One end of the outflow pipe body is connected to the return flow hole on the second fixing plate, and the other end of the outflow pipe body is connected to the return end of the heating flow pipe fitting. It should be noted that the access pipe body 521 is used to access the external hot water pipe body so that hot water can enter the heating flow pipe; the outflow pipe body 522 is used to return the hot water in the heating flow pipe; the access fixing block 523 is used to fix the access pipe body 521; the outflow fixing block 524 is used to fix the outflow pipe body 522.

[0045] See also Figure 6 The heating flow pipe 530 includes a disc heating tube body 531 and a plurality of third fixing blocks 532. Each of the third fixing blocks is disposed on the bottom plate. A third fixing groove is formed on the third fixing block. The disc heating tube body is embedded in each of the third fixing grooves. The inlet end of the disc heating tube body is connected to the inlet tube body, and the return end of the disc heating tube body is connected to the outlet tube body. It should be noted that the disc heating tube body 531 is used to heat the packaging jig, thereby allowing the packaging jig to expand and facilitate the removal of the common-mode inductor from the packaging jig; the third fixing blocks are used to fix the disc heating tube body to the bottom plate. In this way, by allowing hot water to flow into the disc heating tube body, the packaging jig itself will expand to a certain extent, thereby expanding the size of the glue filling groove on the packaging jig. Ultimately, the common-mode inductor after glue injection can be easily demolded, thereby improving the demolding efficiency of the common-mode inductor.

[0046] In this way, by setting up heating fixtures, connecting pipes and heating flow pipes, the principle of thermal expansion and contraction can be utilized. When demolding, hot water can be poured into the heating flow pipes, so that the hot water heats the surface of the packaging jig. Because the packaging jig is made of plastic material, after the outer surface is heated, it will expand to a certain extent, thereby expanding the size of the glue filling groove, and finally making it convenient to demold the common-mode inductor after glue injection, thereby facilitating the demolding of the common-mode inductor, improving the demolding efficiency of the common-mode inductor, and thus improving the production efficiency of the common-mode inductor.

[0047] The advantages and beneficial effects of the present invention compared to the prior art are as follows:

[0048] The present invention relates to a common-mode inductor packaging device. By providing a plurality of packaging jigs distributed in a matrix, burrs can be avoided, so that the surface of the common-mode inductor after glue filling is flat and smooth. The common-mode inductor after glue filling can also be easily removed, thereby improving the production efficiency of the common-mode inductor.
